Assembly type building external wall PC component top reinforcing component and reinforcing method thereof

Abstract

The invention relates to an assembly type building external wall PC component top cast-in-place portion side mold detachable reinforcing component. The assembly type building external wall PC component top cast-in-place portion side mold detachable reinforcing component comprises a superimposition plate, an external wall PC component and a connection steel bar, wherein the external wall PC component is located on one side of the superimposition plate and is connected with the superimposition plate, the connection steel bar is located inside the external wall PC component, the assembly type building external wall PC component top cast-in-place portion side mold detachable reinforcing component further comprises a side mold and a side mold reinforcing device, the side mold is arranged on theexternal wall PC component through the side mold reinforcing device, the side mold reinforcing device comprises a connection sleeve, reinforcing back ribs, a connection plate, a pad block, a reinforcing nut and a screw rod, the connection sleeve is fixedly arranged on the external wall PC component and is provided with a threaded hole corresponding to the screw rod, the number of the reinforcingback ribs is two, the two reinforcing back ribs are connected through the connection plate, and the separation distance between the two reinforcing back ribs is a gap capable of allowing the screw rodto penetrate through. According to the assembly type building external wall PC component top cast-in-place portion side mold detachable reinforcing component, by means of the manner that the outer side of the side mold is designed and configurated with a reinforcing device component, an opposite-pulling reinforcing principle is utilized, and external wall PC component top cast-in-place portion side mold single-side effective reinforcing is realized.

Description

technical field [0001] The invention relates to a reinforcement assembly for the top of a PC component of an exterior wall, in particular to a detachable reinforcement assembly and a reinforcement method for the top cast-in-place part of a PC component of an assembled building exterior wall. Background technique [0002] At present, the country vigorously advocates green and energy-saving buildings, prefabricated buildings, and PC components in the construction industry have been more and more widely used. In the PC structure of prefabricated buildings, there is a joint form: the external wall is a PC component, and cast-in-place concrete is required at the connection between the PC component of the external wall and the laminated slab, and the side formwork of the cast-in-place concrete on the upper part of the PC component of the external wall has no reinforced tension joints. There are often gaps between the side formwork and the PC component at the top of the PC componen...

Problems solved by technology

In the PC structure of prefabricated buildings, there is a joint form: the external wall is a PC component, and cast-in-place concrete is required at the connection between the PC component of the external wall and the laminated slab, and the side formwork of the cast-in-place concrete on the upper part of the PC component of the external wall has no reinforced tension joints. There are often gaps between the side formwork and the PC component at the top of the PC component of the external wall. During the process of concrete pouring, mold expansion and grout leakage occur, resulting in unqualified concrete components. The expansion mold and grout leakage position need to be drilled later.
