Construction method of prefabricated staircase installation structure

Abstract

The invention relates to a construction method of a prefabricated stair mounting structure. The construction method comprises the following steps that (1), fabricated ladder beams and fabricated ladder plates are prepared; (2), ladder column cast-in-place is conducted; (3), a sizing frame is installed; (4), bench placing body is arranged; (5), the fabricated ladder beams are installed; (6), fabricated ladder benches are installed; (7), fastening and grouting construction is conducted; and (8), an anti-cracking screed is arranged. The construction method of the prefabricated stair mounting structure has the beneficial effects that the cross section of each fabricated ladder beam is an inverted T shape, beam top connection screws and shear resistant bodies are arranged on the top face of thefabricated ladder beams, connection strength of the fabricated ladder beams and the fabricated ladder plates can be efficiently improved; the fabricated ladder beams are internally provided with first build-in anchor plates, prestressing force is exerted on a first fasten anchor rod and a second fasten anchor rod through screwing anchor bolts; reinforcing angle bar is synchronously arranged in the reinforcing angle reinforcement embedding slot, interstitial filler is injected at the junction of the fabricated ladder beam and the ladder column, so that the connection strength of the fabricatedladder beam and the ladder column is enhanced from many angles.

Description

technical field [0001] The invention relates to a construction method of a prefabricated staircase installation structure, belongs to the field of building construction engineering, and is suitable for the installation engineering of prefabricated staircases. Background technique [0002] Compared with cast-in-place structures, prefabricated building structures have the advantages of less environmental impact, high construction efficiency, and reliable component quality, and are more and more widely used in housing construction projects. At the same time, as an important part of the building components, the prefabricated installation construction of the stairs has a more obvious impact on the proportion of the building assembly rate. Engineering practice shows that there is still room for further improvement in the quality of prefabricated staircase hoisting and connection construction in the current project, mainly reflected in: the construction efficiency of on-site erecti...

Problems solved by technology

Although this construction method solves the problem of poor reliability of the traditional staircase formwork and improves the construction efficiency to a certain extent, there are still some improvements in improving the integrity of the connection between the ladder plate and the ladder beam and reducing the difficulty of transportation of the prefabricated staircase structure.

[0004] To sum up, although the existing construction methods have achieved good construction results under suitable working conditions, they can enhance the integrity of the connection between the ladder slab and the ladder beam, reduce the difficulty of connection positioning and transportation of the prefabricated staircase structure, and improve the efficiency of on-site construction. There is room for further improvement
