Fabricated prestressed hollow slab floor construction supporting system and construction method

Abstract

The invention provides a fabricated prestressed hollow slab floor construction supporting system and a construction method. The supporting system comprises a plurality of supporting units, and the plurality of supporting units are connected to form one supporting system; and two gate-type scaffolds of each supporting unit are oppositely arranged, steel supports are fixed to the two sides of each gate-type scaffold through rotating buckles, and supporting beams are installed in U-shaped grooves in the tops of the steel supports on the two sides, a prestressed hollow slab is placed on the two supporting beams, and the two sides of the prestressed hollow slab are supported through ring beam formwork angle steel. The technical problems of how to provide support for a prefabricated slab in the construction of a fabricated prestressed continuous hollow slab floor, how to reflect the advantages of the fabricated construction and how to simplify a support system are solved. According to the system and the method, a repartition bar of a connecting portion, post-cast concrete and the like are provided with the support, and thus horizontal load and vertical load generated in construction of the fabricated prestressed hollow slab can be resisted, and the system is not attached to other components and is an independent system.

Description

technical field [0001] The invention relates to an assembled prestressed hollow slab floor construction support system, which belongs to the technical field of prefabricated slab construction support systems. Background technique [0002] Assembled prestressed continuous hollow slab floor technology is a new type of floor assembly technology. At present, the prefabricated construction technology of floor slabs is dominated by laminated slabs, but there are problems of high cost and low efficiency. In order to reduce the amount of cast-in-place concrete for reinforced concrete laminated slabs, reduce the production cost of laminated slabs, simplify the construction process and construction measures, and tap the existing prefabricated slab production capacity, based on the current large-scale and wide-area prestressed concrete hollow slabs, through reasonable construction Structural measures, a new type of laminated floor slab that is simple to manufacture, low in cost, less ...

AI Technical Summary

Problems solved by technology

[0009] In order to resist the horizontal load, a support method similar to that of a full house of scaffolders is generally adopted, relying on numerous rod systems to ensure the lateral stiffness. However, from the perspective of the difference between cast-in-place slabs and prefabricated slabs, this scheme is obviously too conservative. It is unreasonable to increase the lateral stiffness by means of methods, and the support has not been changed from cast-in-place to prefabricated to reduce the amount of engineering
