Preferably, the wall panels are made of plastic.

The application of the plastic wallboard is improved: in the early stage of use, due to the lack of experience in using plastic templates, in summer, the temperature difference is large, and after being spliced in a high-temperature period of morning or afternoon, the spliced seam is 1 to 2mm due to the characteristics of the plastic when the temperature is low, and the seam gradually becomes small until the spliced seam is tightly sealed when the temperature is high.

Therefore, when the temperature is lower, a proper expansion space of 0.5 mm-1mm is required for separating the joint, and when the temperature is higher, the joint needs to be tightly jointed.

Actually measuring actual measurement after the first layer of concrete is poured and demolded, and generating two large deviation items, wherein due to the fact that plastic deformation of a plastic mold is large, the positions of secondary ridges are separated from two sides of the positions of the screws, the positions of the screws bulge outwards, and the distances are as much as 3mm to 6 mm; and forming an arc ridge between the vertical secondary ridge and the middle of two secondary ridges of the concrete wallboard, and measuring a flatness difference value of 2mm to 6mm by using a clearance gauge.

During deviation analysis, the tightness of the screw and the distance between secondary ridges are two main reasons, so that workers are required to control the bolt tightening torque to be 40 to 45N.M when tightening the screw, the secondary ridges are arranged on two sides of the screw, and the clear distance between the rest secondary ridges is controlled to be 140mm to 160mm.

The complete integral construction scheme is as follows:

the construction process comprises the following steps: paying off → checking and accepting of reinforcing steel bar binding of wall board → positioning → opening, splicing board → vertical secondary ridge → combination of steel back ridge → reinforcement → correction → pouring mold viewing → dismantling after maintenance → arrangement.

Opening a hole: according to the template construction scheme trompil, the plate is according to horizontal setting (transversely be favorable to improving the roughness of bottom), for making the plate no matter direction, face, so the trompil all adopts symmetrical arrangement, controls 460mm, and the margin distance 225mm, upper and lower 460mm, margin distance 225mm. And (5) putting plastic pipes and wall thickness stays into the splicing plates. The jointed boards are vertical 40mm 60mm square wood, and the nail pitch is controlled to be about 250 mm.

Vertical secondary corrugation: after the screw rod is placed in the secondary ridge, a back ridge is placed at the middle upper part, the gap between the back ridge and the template ranges from 60mm to 80mm, and the back ridge can be easily discharged into the secondary ridge. The corner adopts 40mm 60mm square timber "L" shape concatenation, fixes with the nail, guarantees among the reinforcement process vertical direction concatenation not to walk the shape, not the opening.

Steel backing and corrugation combination: and (4) combining the steel backing edges after the steel backing edges are completely placed, sleeving the double-beam main rod into the screw, placing the screw into the internal corner, and inserting the pin. The end sockets are special locks, and small wall stacks of 50mm to 200mm optimized by some drawings are combined by special-shaped rods (Z-shaped or L-shaped customized parts).

Reinforcing: after all the components are combined, firstly reinforcing the long wallboard to fix the position of the long wallboard, basically enabling the flatness and the verticality to be matched with the axis, then fixing the position of the internal corner, and using the internal corner to fix the position and square the internal corner when controlling the axis and the verticality; the external corner part adopts 60mm 4.75mm angle steel and the special shaping lockset for the external corner of the small steel plate, a split bolt is penetrated to split and fasten the external corner by 45 degrees, the seal head is reinforced by adopting a hook inward locking mode, and the corner part of the seal head is completely closed and compacted in the longitudinal and transverse directions.

And (3) correction: and (3) correcting after all reinforcement is finished, firstly correcting the main wall board, checking the verticality every 2m, ensuring that the verticality is within the range of 0-2mm, then checking the section size of the wall pile and the short limb, checking the verticality after the size is accurate, basically meeting the requirement of template acceptance by the verticality and the flatness in the other direction after the verticality adjustment in one direction is finished, and then checking whether the screwing degree of each screw is consistent.

Pouring and observing a mold: the special condition is basically not existed during pouring, and bolt looseness caused by excessive vibration is avoided during observation of wallboard vibration.

Maintenance and dismantling: when the square wood is dismantled, the square wood is dismantled by two persons, and the plastic mold is removed and then lightly placed on the ground.

And (3) finishing: and cleaning and oiling concrete bonded on the steel back edge assembly, and lightly scratching away the concrete crackles on the side surface of the plastic mould.

This combination formwork system of steel construction building concrete wallboard adopts the composite wall mould effective control concrete quality defect, improves reinforced concrete shear force wall shaping quality, reduces on-the-spot coping work, according to the standard operation procedure of working as one's office, improves the actual measurement of major structure and repair work, satisfies the requirement of owner to the engineering quality, promotes the satisfaction of builder to the engineering quality.
