Stair steel framework for building

Abstract

The invention discloses a stair steel framework for a building. The stair steel framework for the building comprises two stair main beams, stair cross beams and a stair bottom slab; the stair cross beams are arranged between the two stair main beams, the stair beams are welded to the stair main beams, step vertical ribs are arranged on the stair main beams and are welded to the stair main beams, and reinforcing plates are arranged on the stair main beams and are welded to the stair main beams. The stair steel framework for the architecture fully solves the disadvantages of previous wooden frameworks and is flexible and convenient in installation and disassembly and height adjustment, labor and materials are saved, so that the construction quality is improved effectively and the construction cost is reduced, and the work efficiency is improved; and the quality of concrete forming is good, the stair steel framework is novel and attractive and low in cost and is not prone to being corroding, and can shorten the construction period and bring high efficiency to construction units when the stair steel framework for the building is used, and demoulding of the framework does not need to beworried about during construction.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a steel formwork for stairs used in buildings. Background technique [0002] At present, wooden formwork is mostly used in the process of pouring concrete. It takes a long time for workers to set up the formwork and the efficiency is low. There are many unsafe factors in the construction process. The quality of the components is poor and unsightly. After use, most of the wooden formwork has been deformed and the reuse rate is low. If the number of turnovers exceeds 4 times, it is easy to warp. If it is used improperly, the turnover will not exceed 10 times. It needs joists and corrugated facilities. And it is easy to degumming, drumming, shelling, and cracking. When reassembling, it is difficult to handle the seam of the board, and the thickness tolerance is not easy to grasp, resulting in the deviation of the interface size of the building structure and poor cutting quality. ...

[0002] At present, wooden formwork is mostly used in the process of pouring concrete. It takes a long time for workers to set up the formwork and the efficiency is low. There are many unsafe factors in the construction process. The quality of the components is poor and unsightly. After use, most of the wooden formwork has been deformed and the reuse rate is low. If the number of turnover exceeds 4 times, it is easy to warp. If it is used improperly, the turnover will not exceed 10 times. It requires a lot of joists and corrugated facilities. And it is easy to degumming, drumming, shelling, and cracking. When reassembling, it is difficult to handle the seams of the boards, and the thickness tolerance is not easy to grasp, resulting in deviations in the size of the building structure interface and poor cutting quality. It is necessary to use alloy small-tooth saw blades for cutting. Release agent, and the board surface needs to be treated, the wooden formwork cannot withstand water immersion, especially afraid of being exposed to the sun after soaking in water, the wooden formwork is easy to deform, resulting in uneven concrete surface

[0003] On the construction site, the most difficult thing to control is the operation process of woodworkers using wooden formwork. If the material management of wooden formwork is not strengthened, and the materials are cut and assembled strictly according to the assembly drawing of wooden formwork, it is easy to cause waste of wood formwork materials and increase project costs.
