The color board house is believed to be unfamiliar to everyone. It belongs to the construction site and is reusable due to its quality characteristics. After the project is completed, the dismantled color board room will be transferred to a new construction site for assembly and reuse. However, the safety issue has also gradually attracted people's attention. Especially when the weather is hot, the color plate house fires are more frequent and require special attention. Next, Xiao Bian introduced the construction method of the color board house and the removal steps of the color board room.
Color board house construction method
1, materials approach
(1) Materials entering the market, manufacturers should attach the original factory material inspection certificate.
(2) Check the specifications, dimensions, and thickness of the molding plate and purlins.
(3) Check the specifications, dimensions, and thickness of various blanking materials.
(4) Inspection of spare parts (self-tapping screws, gaskets, sealing glue, etc.).
(5) The appearance of the color steel plate must not be dragging, scratches, stains, surface film wear, distortion, pollution, color, warping and so on.
(6) Materials entering the site should be stacked in the designated area of ​​Party A. At the same time, Party B shall be responsible for the safety measures for this part of the materials. The materials shall be properly packaged to avoid damage.
2, lifting
(1) Before the material enters the site to set up a designated place, it must be batched, classified, and placed separately. When it cannot be used immediately, it should be stacked neatly and covered with canvas or tape.
(2) When laying materials on the ground, sleepers must be laid to keep them dry (more than 6 cm above the sleepers). The materials must not touch the ground. The spacing between the sleepers should not exceed 3 meters.
(3)Before the material is hoisted to the truss, it should be strapped tightly with steel straps.
3, material hoisting truss construction points
(1) Placing the truss of the steel plate and setting the baffle plate to prevent the steel plate from slipping before the steel plate is lifted.
(2) When the material is hoisted to the truss, the distance between the vertical straps tied to the colored steel plate on the suspender shall be no more than 6 meters, and diagonal slings shall be added at both ends to prevent slippage. (The weight of each bundle must not exceed 2 tons)
(3) Keep lifting smoothly and slowly, within the scope of crane operation, non-lifting personnel shall not approach.
(4) During the lifting process, if there is looseness in the vertical strap of the colored steel plate, it shall be put down and re-adjusted and then hoisted.
(5) The colored steel plate slowly descends, and is to be laid down in order after the crane operator controls the positioning (kneading gate).
(6) After the material is hung to the truss, all the leather ribs shall face upward, the surface of the plate shall face in the same direction (easy to install, except for the sinuous ribs), and shall be fixed on the steel main frame with a nylon rope (not to be placed in the skein central).
4, color steel plate laying and fixing
The order of laying color steel plates is, in principle, from top to bottom, starting from the end of the year.
(1) Roofing
a. Take the gable side as a starting point, laying from left to right (or right and left) in order.
b. After the first sheet is set up, pull the line along the lower edge of the plate. Each sheet is installed on the guideline. Check at any time to avoid deviation.
c. Laying the surface with self-tapping screws and fix it on the rib along the center of each rib.
(2) Edge
a, roof (including awning) edge material overlap, must be fixed with aluminum rivets and waterproof glue.
b. Self-tapping screw heads and aluminum pull nail heads on the side of the roof shall be prevented by water stop glue.
c. Roof cover and cornices (including gutters) shall be covered with mountain foam PE sealing strips.
d. When the edge board construction method is fixed and the change is required at the site measurement, the post-acquisition drawing shall prevail.
(3) The construction principle is the same as the self-tapping screw construction method. Only the board fixing method is changed (fixed seat). The fixing method is as follows:
a. The first row of the first fixed seat is fixed to the leftmost side of the purlin with a self-tapping screw, and then it is used as a reference line in the purlin ball line, and then the same row of the fixed seat is fixed.
b. The ribs of the first plate are aligned with the ribs of the holder and pressed into the bag to check if the snap-fit ​​is correct.
c. Fasten the short arm of the fixing seat to the first panel of ribs that have been laid. Construct according to the method described above and adjust it flush.
d, laying in the above order, the last remaining room in the air is less than half the width of the board, only the fixed seat short arm fixed plate, and the rest of the space to take the water.
e. If the last remaining space is greater than half the width of the board, the board is fixed with a fixed seat and the excess part is cut off.
(4) Cleaning and waste disposal
a. When laying steel plate area, when cutting iron work and fixing screws, the generated metal shavings should be cleaned before daily work.
b. The debris (such as PVC cloth, steel tape, etc.) on the roof, floor and gutter needs to be cleaned before daily work.
c. The remaining scraps to be cut during construction should be sent and collected by people every day.
d. All waste materials must be cleaned and disposed before completion.
e. The surface of the colored steel plate should be inspected after completion. The contaminated part should be cleaned.
(5) Precautions
a. When the color steel plate is cut, its exposed surface should face down to avoid the swarf generated when cutting is attached to the coating surface, causing the swarf to gasify.
b. When the construction workers walk on the roof, they should step on the valley along the drainage direction. They should step on the purlins in the direction of the purlins and wear soft flat shoes.
c. When the roof is to be longitudinally (rowwise) overlapped, the overlapping length should be more than 15cm. The sealing glue should be applied according to the design drawings. The overlapping position should be in the position of the sliver (the wall overlaps the length In more than 10 centimeters, place it on the yoke.)
d. Self-tapping screws are fixed on the ribs. The depressions are based on the principle of self-tapping screws and the center line of the ribs. The ±1.5mm is acceptable. The over-tight portions should be filled with waterproof glue. The loose parts should be re-locked.
e. When the daily work is to be done, the color steel plate material on which the roof trusses and the ground are placed should be firmly tied with nylon rope or twine.
f. The self-tapping screws must support the surface vertically, and the washer must be tight.
Choi board room removal steps
1. The demolition of color board houses shall be in accordance with the correct demolition order, ie starting from the wall panels, and successively demolishing the roof panels, purlins, high-strength bolts, steel beams, steel columns, embedded bolts, and embedded steel plates;
2. Dismantling operations shall be performed from top to bottom and in accordance with the sequence of operations. Operators shall cooperate with each other; and shall prevent simultaneous dismantlement at high and low levels, and shall not dismantle the partition boards first;
3. Infrared and warning signs shall be installed in the dismantling area to prevent unrelated personnel from entering the dismantling site;
4. In case of unfavorable weather such as strong winds, heavy fog, and heavy rain above Class 5, the demolition work shall not be carried out;
5, before the demolition should first remove or cut off the power within the steel structure;
6, the demolition personnel is best professionals, and the operation of the insurance must be fastened.
Editor's summary: The construction method of the color board house and the removal procedure of the color board room are introduced here. I hope to help everyone. If you want to know more related information, you can pay attention to this website information.

Monel alloy 400 has excellent mechanical properties at subzero temperatures. Strength and hardness increase with only slight impairment of ductility or impact resistance. The alloy does not undergo a ductile-to-brittle transition even when cooled to the temperature of liquid hydrogen. This is in marked contrast to many ferrous materials which are brittle at low temperatures despite their increased strength.
