Technical Field

This patent relates to template equipment that uses on the building engineering.

Background

In a high-rise building of a building construction project, the inclined wall part of the skirt building is special, the beam slab of the lower floor is positioned in a high formwork supporting area, the upper opening of the wall body is inclined outwards, and the high-altitude large-size inclined wall is difficult to support and stabilize and is overlapped with the lower high formwork supporting area, so that the construction difficulty is greatly increased. Generally, the construction sequence is adjusted reasonably by means of sectional layering, a lower high formwork system corresponding to the inclined wall is constructed in advance to stabilize the base, and when the concrete of the lower high formwork beam plate reaches the designed strength, the concrete of the inclined wall is poured. The common method is as follows: and a high formwork bent is erected outside the inclined wall and bears outward horizontal thrust generated by the inclined wall. The high formwork bent has complex construction measures, difficult connection with a cast-in-place structure, complex process (a plurality of holes need to be reserved in the inclined wall so as to be convenient for a bent cross rod to pass through), high safety risk, more accidental factors, and difficult calculation and quantization of the horizontal force resisting of the high formwork bent.

Embedding a phi 12mm drag hook according to a corresponding position when pouring floor concrete, and anchoring the drag hook into a plate; the draw hooks correspond to the diagonal draw steel bars one by one and are connected by adopting turnbuckle bolts to adjust the length of the draw bars and correct the position of the wall formwork. The turnbuckle bolt is OO type, the number of the turnbuckle is 1.7, and the allowable load force is 17 kN. The beams at the lower part of the inclined wall and the corresponding beam plates belong to the category of high formwork, and after the strength of the beam plates reaches the design requirement, a stable base is formed. The bent frame at the upward part of the floor is used as a protective working plane for operators and is not used as a stress framework of the inclined wall.

And the tie bar and the upper threaded steel bar are connected by welding → the embedded steel bar at the root part of the tie bar and the turnbuckle are connected → the tie bar passes through the wall template, and the outer side surface is fixed with a node by double nuts → the construction of the inclined wall template → the template removal.

When the top beam plate is poured, firstly pouring the inner shaft frame column of the inclined wall in advance by more than 2 d; the frame columns and the inclined wall template are in effective rigid connection by adopting steel pipe fasteners, so that the safety storage of the inclined wall plate is increased; arranging technical and safety personnel to carry out real-time monitoring when the inclined wall is poured according to the requirement of a high formwork; before the strength of the beam slab concrete of the floor at the top of the inclined wall reaches 70 percent, inclined wall templates cannot be loosened and dismantled, and inclined pull steel bars and turn-buckle bolts cannot be loosened.
