Embodiment 1

[0034] Such as Figure 4 As shown, it is a slab-slab splicing structure within a span, and the splicing objects are prefabricated floor 1-1 spliced ​​within a span and prefabricated floor 2 spliced ​​within a span 2-1, prefabricated floor 1-1 spliced ​​within a span and prefabricated floor spliced ​​within a span The floor plate two 2-1 is respectively provided with a plurality of smooth and curved first rope-through holes 3 and second rope-through holes 4 inwardly from the splicing edge (see details). figure 1). Since the slabs are spliced ​​across the span, the first rope-threading hole 3 and the second rope-threading hole 4 are respectively located below the midplane of the spliced ​​prefabricated floor 1-1 within the span and the prefabricated floor 2 2-1 spliced ​​across the span. This ensures that the first steel wire rope 7 and the second steel wire rope 8 inserted later can effectively resist the action of the downward bending moment at the splicing part.

Embodiment 2

[0037] Such as Figure 5 As shown, it is a splicing structure at the slab support, and the splicing objects are splicing prefabricated floor 1-2 at the support and prefabricated floor 2 2-2 at the support, splicing prefabricated floor 1-2 and Splicing the prefabricated floor 2 2-2 at the support is respectively provided with several smooth curve-shaped first stringing holes 3 and second stringing holes 4 inwardly from the splicing edge (see details). figure 1 ). Due to the splicing connection at the slab support, the first stringing hole 3 and the second stringing hole 4 are above the middle planes of the spliced ​​prefabricated floor 1-2 at the support and the spliced ​​prefabricated floor 2 2-2 at the support respectively position, so as to ensure that the first steel wire rope 7 and the second steel wire rope 8 that are inserted later can effectively resist the downward bending moment of the splicing position.

Embodiment 3

[0040] Such as Figure 6 As shown, it is a wall vertical splicing structure, and the splicing objects are vertically splicing prefabricated wall panels 1-3 and vertically splicing prefabricated wall panels 2-3, vertically splicing prefabricated wall panels 1-3 and vertical To the splicing prefabricated wall panel two 2-3, be respectively provided with the first threading hole 3 of several smooth curves and the second threading hole 4 (see details) inwardly from the splicing edge figure 1 ). Preferably, the first stringing hole 3 and the second stringing hole 4 are respectively located at the midplanes of the vertically spliced ​​prefabricated wall panel one 1-3 and the vertically spliced ​​prefabricated wall panel two 2-3.

[0041] Before splicing and assembling, first go around and pass through the first wire rope 7 in the first stringing hole 3 and the second stringing hole 4 of the vertical splicing prefabricated wall panel 1-3 and the vertical splicing prefabricated wall ...

Abstract

The invention discloses a steel wire rope hooking-splicing structure and method for prefabricated concrete wallboard-type components. A first prefabricated component and a second prefabricated component which are in a wallboard shape are spliced; the first prefabricated component is perpendicular to a splicing surface and inwards provided with a set of smooth-curve-shaped first rope threading holes formed at intervals, and the second prefabricated component is perpendicular to a splicing surface and inwards provided with a set of smooth-curve-shaped second rope threading holes formed at intervals; and the positions of the first rope threading holes and the second rope threading holes are symmetrical in the transverse direction and the heights of the first rope threading holes and the second rope threading holes are the same in the longitudinal direction relative to the slicing surface. According to the steel wire rope hooking-splicing structure and method for the prefabricated concrete wallboard-type components, the problems that steel bar exposure occurs to the periphery of an existing wallboard-type splicing prefabricated component, and therefore the prefabricated component is complex in side formwork, low in production efficiency, difficult to transport and hoist and the like are solved; the problems that overlapping pouring of an existing prefabricated assembly floor structure is conducted, therefore a large amount of on-site wet construction occurs, and decorative layer construction cannot be completed in a prefabricated plant are solved; and the problem that the construction quality and efficiency are low due to connecting of grouting sleeves of an existing prefabricated assembly wallboard structure is solved.

Description

technical field [0001] The invention relates to a splicing connection structure and method of prefabricated concrete wall panel components, belonging to construction engineering technology. Background technique [0002] In recent years, with the continuous improvement of people's requirements for living conditions and living environment, the construction industry has developed rapidly. However, the development of the construction industry has caused serious resource consumption and environmental pollution, forcing people to seek a new way out of the construction industry. At present, the industrialization of buildings characterized by prefabricated buildings is one of the key ways to achieve low-carbon and sustainable development in the construction industry. [0003] In prefabricated buildings, the connection mode between structural components has a crucial influence on the efficiency of prefabricated and assembled construction and the mechanical properties of service.
