2, Installation of concrete runway beam.

The assembly method has not obstacles so we can choose the Jib which slide (sin 75=0.966, cos75=0.259, tan75=3.732) as geometrical method, we can choose the parameters as below.a, inside runway beam. The required height of jib: Hyc= Hmc +hcab= HL+a +hel+heq +hcabIn which: HL= the height of erection (8.6m)a= 0.5m the gap from the ground to bottom of member.Hel : the height of element. (0.6m)Heq: the height of lifting equipment. (2.4m)Hcab : the height of cable.(1.5m) Hyc=8.6+0.5+0.6+2.4+1.5=13.1m

5, Installation of roof panel. Roof panel is light weight, but it also has a obstacle in front of which is a roof truss. Therefore , we should choose the distance between the cable and the panel in safety , choose e = 1 (m) Choose parameters at the place where the panel is the highest with 2 situations : jibs and without jibs. Due to geometric method we have the diagram to choose the parameters for crane :

a) Erect the panel for the center span : The situation without jib : H = 15.7 (m)

0.00 The situation with jib :

=750 => = 3.732 l = 3.7 (m)

=> Lyc = +

=> Lmin = + =16.8 m.

S = *Cos750 = 4.05 m.=> Ryc = 4.05 + 1.5 + 1+3 =9.55 m. Q = Pck + qtb = 1.55T

0.00b) Erect the panel for the outside span The situation without jib : H = 9.2 m

The situation with jib :

=750 => = 3.732 l = 3.8 (m)

=> Lyc = +

=> Lmin = + =9.7 m.

S = *Cos750 = 2.3 m.=> Ryc = 2.3 + 1.5 + 1+3 =7.8 m. Q = Pck + qtb = 1.55T

CHAPTER III: TECHNICAL METHODS.Base on the parameters of crane that is chose above and the present condition construction of plan to determine the position of crane for erection.1.Column installation.Use the crane that name is KX-5363(L=20m) to assembly the both inside column and outside column with parameters which is mentioned above.1.1. The position and transportation of diagram of crane.+ From the zone of action of crane corresponds each member (the area allows the crane that stands and acts). We identify the zone of erection for all elements. + The crane goes straight between the both rows of column. And each the place, it can assembly two side as shown in figure.+ The minimum boom outreach of crane is Rmin = 7m; the weight of column Q = 5.88 (ton) The maximum boom outreach of crane is Rmax = 9mTherefore, It is shown in figure : 1.2 Construction methods. Preparation.+) Transport columns from the factory to the site by truck or lorry. Using crane to lift and arrange these columns on the site as shown in figure+) On the surface of foundation where marked exactly the position of columns and there were wood pad, timber and guy wire.+) Marking all the central lines of columns and marking the level at the determined point in the column.+) Checking the dimension of columns : the width, the height, the section. Checking bolts which link the columns to the run-way beams such as : the position of joint; the quality of bolt and the screw of all column. All of them need to satisfy the quality and the quantity.+) Checking lifting equipments such as : the wires ( no break) , friction belt, temporary fixed equipments ( wedge, turn buckle, jack lift and brace ) +) Preparing the aggregate of hearting concrete to link to the foundation as design. ERECTION.+) Set up the friction belt into the body of system , pour a concrete layer into the socket foundation. +) Connecting the lifting system to the hook of crane, the crane lift the column to the position where is 0,5m from the surface of foundation. We use wagons and some special equipments to drag the column and we can reduce the friction.+) The labour use rope system to set up the column into the centroid of foundation and then lower the crane gradually to install the column into foundation.+) Using 5 wood wedges and 4 turn buckles to fix temporarily, and then using theodolite to adjust the position of column and using gradienter to adjust the level of column, contortion the turn buckle and install the wedge in appropriate way. If the level still does not satisfy , we will change the thickness of concrete layer in the foundation.+) In conclusion, cleaning the base of column and using cement mortar with high strength to link the column , mortar grade > 20% the concrete grade of foundation and columns. Fixing the masonry hollow joint into 2 processes : The first process : pour concrete to the bottom of the wedge The second process : when the mortar grade reaches to 80% we can get the wedge out and pour concrete fully to the foundation.

1. Erecting the crane runway beam.Using crane MKG-16 ( L = 18,5 m )1.1. The diagram of moving craneThe minimum boom outreach of crane is Rmin = 6m ; the weight of crane runway beam Q = 3.31 (ton) The maximum boom outreach of crane is Rmax = 8.7mTherefore, we can erect them by the way that the crane may run along the edge of range column. As shown in figure: 1.2. The standing position of crane.The standing position of crane must ensure that the crane can assemble 2 crane runway beam ( in one bay column ) in the central span. The number of standing position of crane is 2 in outside span , 3 in inside span.1.3. Construction method. Preparation+) Using truck to transport crane runway beams to gather at site and put along the range of column.+) Checking the dimension of crane runway beam ( length, width, ..) , bolts and the steel pad for connecting of crane runway beam ( quantity and position )+) Checking hanging and tie equipments, fasten or replace if necessary.+) Checking the level of console by level theodolite , mark the centroid of beam, checking the distance of column+) Preparing steel pads, connected equipments such as : bolts, spike driver , welding rod and band saw brazing machine+) Hanging and tie equipments must be putted in the right position. Lifting+) Installing the hook of crane in hanging and tie equipments of crane runway beam, lifting crane runway beam up, labours use wire to control the position of beam.+) 2 labours will stand in 2 working platform where are on the top of column to control the beam in right connection and position. If there are any backlash we will use steel pads.+) In conclusion , we weld and drive bolts permanently.3. STEEL TRUSS AND OPENING WINDOW INSTALLATION.Use the crane that name is XKG-30/35m to erect the steel truss and opening window.3.1. position of crane and diagram of transportation.- Diagram of transportation: crane goes between the inside span.- determine the place of crane: the location of crane is determined following the minimum radius and maximum radius of crane that must be corresponded with the weight of truss, position of truss.+ install the truss.-Maximum radius: Rmax=16m- The crane must lift the truss that has weight equal P=3.65 (ton)All the things are illustrated in the figure bottom.+ install the concrete beam -maximum radius: Rmax=16mThe crane must lift the truss that has weight equal P=4.63(ton)3.2 Technical installation.+ Preparation: after labor had fixed permanent the column into the foundation, we determine the center line to erect another member. + Adjustment and strengthening for truss before erecting it on the column.+ When truss is erected, truss is fixed temporary at three points and we use the brace bar and tuner buckle. Each truss is fixed temporary at 2 head points and a center point.+ Check and adjust the vertical plan of truss compared with vertical plan.+ fix permanent the truss after the all technical requirement is ensured as design.4. Roof panel installation.4.1 Diagram of transportation.Use the crane XKG-30/35m that go inside span.4.2 Position of crane.- determine the place of crane: the location of crane is determined following the minimum radius and maximum radius of crane that must be corresponded with the weight of panel, position of panel.+ install the roof panel.-maximum radius: Rmax=16m- The crane must lift the truss that has weight equal P=1.55 And critical height H=15.7m4.3 Technical installation.+ Preparation: the truss is pined on the column. After that, we lift the panel at four points and also use the automatic-balance pulley.+ The panel is erected from border to opening window. It is also noticeable that we have to determine the location of panel on the roof to avoid the accumulation on the roof. On the opening window, the panel is erected from one head to other head.+ check and adjust the location of panel as design.+ The panel is fixed permanent after the all technical requirement is ensured as design. 5. Wall panel installation.5.1 Diagram of transportation.Use the crane KX-3461/25m that go straight outside wall.5.2 Position of crane.- determine the place of crane: the location of crane is determined following the minimum radius and maximum radius of crane that must be corresponded with the weight of panel, position of panel.+ install the panel.- Minimum radius: Rmin=7.5m-Maximum radius: Rmax=15m- The crane must lift the wall panel that has weight equal P=0.78(ton) And critical height H=15.1m5.3. Technical installation.+ Preparation: after pouring the concrete into the bracing foundation, we use truck to prepare the wall panel. The panel is hung by lifting cable and automatic-balance pulley with two points.+ Assembly and temporary fixation: erect the wall from bottom to top+ Check and adjust location of panel as design.+ Fixation permanent: The panel is fixed permanent after the all technical requirement is ensured as design IV. Safety technique in assembling. Assembling often proceed at high level so labours need to have a good healthy ( no vertigo, no headache) . When giving new jobs to labours at the high level , engineer must inform some technical requirements and safety methods in a detail way. Giving to labours who work at high level some special clothes such as : tidy, not sliny shoes, protection gloves and safety belt. These belts must stand static forces which reach to 300 kg. Forbid strictly connecting these safety belt to unreliable structure. When lifting structural element up to 0.5m we must stop and wait for 1-2 minutes to check the safety of hooks. No standing under elements which are lifting and installing. Labours must stand outside the rotated radius. There must be barriers and warning light at night (or guards ) to prohibit traffic at the site. Electric wire must not run over lifting and assembling areas , if not they must run underground. Prohibit labours to stand on the lifting elements. Hooks must have safety equipments to avoid slipping. No pull these components in horizontal because the crane can be turned over. Not hanging any weight into the jib in break time. Only remove hooks when the components is stable. Platform working must be stable , there should be balcony with 1m in height. The chink between the inside edge of deck and elements must be less than 10cm. Checking regularly, fixing decks and platform working. Prohibit traffic on the upper side of jack rafter, beam and braces. Only walk on the downside of frame when cables lift elements up 1m. There should be temporary lightning resistant for high rise building . The popular method is that using temporary conductor, lighting rod made by metal and it connects to the ground.
