Mold for constructing sandwich structure prefabricated wall panel and molding method

Abstract

The invention relates to a mold for constructing a sandwich structure prefabricated wall panel. The mold comprises inner sheet edge baffles and first outer sheet edge baffles detachably fixed to the tops of the inner sheet edge baffles. First accommodating slots for allowing steel bars to penetrate through are formed in the bar outlet positions of the inner sheet edge baffles correspondingly. Thetop of each first accommodating slot is open. The open end of each first accommodating slot is through in the top of the corresponding inner sheet edge baffle. The mold provided by the invention is reasonable in structure. On the premise of not increasing the cost basically, the demolding process is greatly simplified, and the production efficiency is improved. Moreover, through cooperation of flexible molding films and the edge baffles, the mold can achieve the effect of preventing grout leakage and saving concrete materials while the demolding process is simplified.

Description

technical field [0001] The invention relates to a mold and a forming method for constructing a sandwich structure prefabricated wallboard, in particular to a mold and a forming method for constructing a sandwich structure prefabricated wallboard, belonging to the technical field of construction. Background technique [0002] Prefabricated concrete components are building components prefabricated in factories with concrete as the basic material, including prefabricated building components such as walls, beams, panels, and columns. Since prefabricated components need to be connected with other components to form strength, protruding steel bars are often reserved on the outer surface of prefabricated components. These reserved steel bars are called ribs because they protrude on the outer surface of the prefabricated components. When the ends of the two ribs of the prefabricated part are connected by steel bars to form a closed structure, the ribs at this time are called stirru...

AI Technical Summary

Problems solved by technology

When demoulding, it is necessary to pull the mold for a certain distance along the length of the ribs before demoulding, so the work intensity of the workers is very high, and the template is easy to be damaged

[0005] The existing prefabricated wall panels are generally sandwich structures, including inner wall panels and outer wall panels. The outer wall panels are generally composed of insulation layers and surface layers, and the three structural layers can be connected by glass fiber bars; the existing In the production of prefabricated wall panels, the reinforcements are generally placed on the corresponding molds first, and the concrete is poured for curing and forming. After the forming is completed, all the surrounding ribs need to be removed one by one to complete the demoulding, which requires long hours and low work efficiency. low
