. On-site installation
1) Measure whether the axis dimensions of each wall foundation meet the requirements of the drawings, and the deviation of the axis dimensions should not exceed plus or minus
25mm. The deviation of the wall foundation height measurement should not be greater than plus or minus 10mm.
2) When the materials arrive at the site, unload them first and reasonably transport the materials to each construction point. Handle the materials with care during transportation to avoid damage. After the materials are properly positioned, check the shape and size of the steel components and the welding quality before construction.
3) According to the drawing dimensions, bury the chassis iron and fix it to the foundation with expansion screws.
4) Assemble the steel components. Assemble the square tube columns and steel beams one by one with screws. Tighten all the screws during assembly. Check whether the steel beams are vertical and in the same plane, and whether the component dimensions meet the specified requirements until fully satisfied.
5) Install the assembled steel components one by one. Prop up the first steel beam. After the steel beam is propped up, support it firmly with square tube columns. Adjust the first steel beam with a plumb line to make it vertical to the ground. Measure the dimensions accurately with a steel tape measure, then prop up the second beam. The installation method is the same as above. Then install the sheet beams and fix them to the main beams with screws. The remaining main beams and sheet beams can be installed in place according to the above steps, and check again whether the position of the steel beams is accurate. If there is a deviation, adjustment is still required.
6) After confirming that there are no errors, weld the horizontal supports and the through frames inside the steel beams with angle irons, and then weld the square tube columns and the chassis iron. 7) After the installation of columns and beams is completed, install the floor slabs. The joints between the floor slabs should be tight.
8) After the floor slabs are laid, start installing the wall panels. When installing the wall panels, reserve the positions for doors and windows. After all the exterior walls are installed, start installing the roof panels. After covering the roof panels, complete all the work on the roof panels first, including installing the fascia boards, conducting waterproof treatment, and installing the roof covers, etc.
9) After the overall installation of the house is completed, install the doors and windows. Pay attention to making the installation of the windows airtight, and there should be no gaps between the windows and the wall panels. After the windows are installed, conduct waterproof treatment. The doors should be installed flat and straight.
10) Install the floor slabs and railings. The railings should be straight and firmly connected to the railing posts. The stair steps are made of checkered steel plates or angle irons. The floor slabs should not shake. The stairs should be fixed to the gable walls. The railing plates should be fixed to the stairs with 75mm self-drilling self-tapping screws.
11) Notify the user to pour the upper floor. After the wires are installed, install the lower PVC ceiling panels. After the ceiling panels are installed, notify Party A to pour the lower floor.
12) Conduct a self-inspection after the project is completed.
13) Conduct an overall acceptance of the house together with the user.
6. Erection and reinforcement measures
1) On the upper floor of the second - story movable house. The 80×80 square tube columns reach the top. 4# angle irons (or 4×6 flat tubes) are used between the columns and are fixed with screws (or by electric welding). From the top of the roof downwards, 125mm self - drilling self - tapping screws are used to fix the 4# angle irons (or 4×6 flat tubes).
2) Add 125mm self - drilling self - tapping screws to fix the balcony to the angle irons.
3) In order to prevent the load of snow in winter, install cross - beams in the middle of the movable house. Use 4×6 flat tubes (or color steel plate beams) to prevent the roof from being crushed by heavy snow. According to the user's requirements, snow - resistance reinforcement is generally only considered for large open - plan rooms.
