Production device and construction method for two-way core drawing prefabricated hollow seismic wall panel

Abstract

The invention discloses a production device and a construction method for a two-way core drawing prefabricated hollow seismic wall panel. The production device and the construction method are used forproducing the prefabricated seismic hollow wall panel; and core pipe platforms, a mold platform and an auxiliary device are included; the mold platform comprises a molding mold and a work table, thecore pipe platforms are symmetrically arranged on the two sides of the mold platform, and each core pipe platform includes a core pipe frame, a core pipe rail and a core drawing oil cylinder, whereinthe core drawing oil cylinder pulls the core pipe frame to move on the core pipe rail, the core pipe frame comprises a fixed core pipe set, a movable core pipe set and a moving frame, the fixed core pipe set is fixedly connected to the moving frame, and the movable core pipe set is movably connected to the moving frame. A two-way core pulling process is adopted, the core drawing stroke is reduced,the concrete adhesion force during core drawing is reduced, and the hole forming quality of a hollow hole is ensured; the relative movement of the fixed core pipe set and the movable core pipe set during core drawing ensures the hole forming quality, and hole wall collapses during wire drawing are prevented; and the production device and the construction method have the advantages of mechanization, the high automation degree and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of assembly-type wallboard production, in particular to a production device and construction method of a bidirectional core-pulling prefabricated hollow anti-seismic wallboard. Background technique [0002] At present, domestic prefabricated building components are mostly floor slabs, exterior wall panels, stairs, balconies, air-conditioning panels, etc., while load-bearing walls, including shear walls and load-bearing exterior walls, are mostly cast-in-situ, and some buildings use solid prefabricated shear wall technology. . This kind of prefabricated building based on the traditional cast-in-place concrete structure thinking design results in a low overall building assembly rate. With the advancement of construction technology and the requirements for construction progress, more and more prefabricated concrete wall panels are used as building components during construction. Assembling directly during cons...

Problems solved by technology

In the production process, the production process is complex, the degree of mechanization is low, it basically relies on manual work, the efficiency is low, and the energy consumption during maintenance is high. In addition, the hollow slab is only used as a template for the shear wall. In actual use, it needs to be inserted into the core hole. Pouring concrete, neither saves concrete consumption nor improves efficiency

[0005] Existing technology 3: Hollow wall panels are processed on the production line, that is, the two sides are prefabricated concrete thin slabs connected by a steel skeleton in the middle, and the hollow part is filled with concrete after installation in place, which is actually quite a solid cast-in-place panel; This solution has a high degree of automation, but the transportation cost of the hol
