A steel frame skeleton prefabricated formwork assembly integrated RC pipe gallery and its construction method

Abstract

The invention discloses a steel frame skeleton prefabricated formwork assembled integral RC pipe gallery and a construction method thereof. The steel frame skeleton prefabricated formwork assembled integral RC pipe gallery is characterized in that several sections of steel frame skeleton prefabricated formwork are segment by section The integral formwork formed by connection and the concrete poured in the integral formwork, the prefabricated formwork of the steel frame skeleton is composed of a steel frame and a reinforced concrete slab, and the reinforced concrete slab is assembled on the steel frame by bolts On both sides, the prefabricated formwork of the steel frame skeleton is composed of the bottom plate of the pipe gallery, several side walls of the pipe gallery and the prefabricated formwork of the steel frame skeleton of the roof. The prefabricated formwork of the inter-steel frame skeleton forms an integral formwork through the connection between the steel frames in it. The present invention also provides a specific construction method for the above assembled integrated RC pipe gallery, which is characterized by simple procedures and easy construction quality assurance.

Description

technical field [0001] The invention belongs to the technical field of comprehensive pipe gallery, and in particular relates to a steel frame skeleton prefabricated formwork assembled integral RC pipe gallery and a construction method. Background technique [0002] With the determination of pilot provinces and cities for comprehensive pipe corridors in my country, the construction of comprehensive pipe corridors has entered a period of rapid development. At present, the structural forms of comprehensive pipe corridors in my country mainly include cast-in-place structures and prefabricated structures. The cast-in-place structure has the advantages of good structural integrity, good safety, and good water resistance. However, the cast-in-place structure has complex construction procedures, long construction periods, difficult construction quality assurance, high cost, large resource consumption, and is affected by weather and site conditions. Large, large pollution to the sur...

Problems solved by technology

Prefabricated structures are commonly divided into two methods: integral prefabrication and prefabricated prefabrication. Integral prefabrication is to divide the pipe gallery into sections, and prefabricate several integral pipe gallery sections by centrifugal or vibrating pouring in the factory, and then transport them to the site for construction. Assembling, the disadvantage of this method is that the size and weight of the components are large, and the specifications are restricted by production conditions. It is difficult to have production equipment and cannot manufacture super-large components. The investment in production equipment and hoisting equipment is huge, and transportation and hoisting are difficult. At the same time, assembly There are many joints, the on-site assembly process is difficult, and the waterproof treatment process at the joints is complicated, and the construction quality is difficult to guarantee; prefabricated prefabrication means that the bottom plate, side wall, and roof of the pipe gallery are prefabricated separately in the factory and assembled on site.

Although this method overcomes a series of technical problems caused by the large volume and weight of the integral prefabrication, there are too many assembled components, poor structural integrity, poor stability, poor force transmission effect, and too many joints, resulting in The pipe gallery is difficult to waterproof and other defects, so that there are hidden dangers in the structural safety and durability of the pipe gallery during use
