Prestressed truss plate for manufacturing building wall and building wall manufactured by the same

Abstract

The invention provides a prestressed truss plate for manufacturing a building wall. The prestressed truss plate for manufacturing the building wall comprises the prestressed truss plate, wherein the prestressed truss plate is a concrete plate in which prestressed steel is pre-embedded; multiple groups of trusses are arranged on the prestressed truss plate in parallel; each truss comprises a trussupper chord; truss web bars are arranged at the two sides of the truss upper chord; the lower parts of the truss web bars are pre-embedded in the prestressed truss plate; the prestressed steel is perpendicular to the truss upper chord and is located at the middle position of the thickness of the prestressed truss plate; the concrete plates with the trusses are spliced at a construction site to form a hollow wall plate prefabricated part; and the hollow wall plate prefabricated part can be used for forming a shear wall or a light partition wall by casting. The prestressed truss plate has low processing difficulty and high rate of finished products and is convenient to transport. The trusses which are mutually staggered between the concrete plates can ensure that the distance in the hollow wall is equal everywhere; the concrete plates serving as molds do not need to be dismantled after the casting is completed; a whole wall without joints is formed among various walls and embedded columns; and cracks on the wall do not appear.

Description

technical field [0001] The invention relates to a building prefabricated component, in particular to a prestressed truss plate for making a building wall and the building wall made therefrom. Background technique [0002] At present, the production of building walls is mostly to prefabricate two formworks in advance, insert steel bars or bolts to play a pre-tightening role between the two formworks, and then pour concrete between the two formworks. The distance cannot be guaranteed, and it is easy to make the poured wall skew, and after the wall is poured, the external formwork must be removed and the protruding pre-tightened steel bars or bolts on the wall must be removed, which is not only time-consuming and laborious, but also The overall quality of the body is still not guaranteed. At the same time, the concrete prefabricated wall panels used as formwork are limited by the thickness of the building wall. The thickness is relatively thin, and the rigidity and compressive ...

The thickness is relatively thin, and the rigidity and compressive strength are limited. easily broken
