Embodiment 1

[0037] Embodiments of the present invention provide a connection system between prefabricated laminated foundations and fully prefabricated shear walls, such as Figure 1-5 As shown, it includes a prefabricated concrete composite foundation 100 and a fully prefabricated shear wall 200, wherein:

[0038] The precast concrete composite foundation 100 includes an outer wall panel 101 and at least one inner partition 102 arranged in the outer wall panel 101. The inner partition 102 divides the interior of the outer wall panel 101 into several cavities 103. Each inner partition A positioning groove 104 is formed on the top of the 102 .

[0039] The bottom of the fully prefabricated shear wall 200 is provided with reserved longitudinal reinforcement 201, the bottom edge of the fully prefabricated shear wall 200 is stuck in the positioning groove 104, the reserved longitudinal reinforcement 201 is inserted into the cavity 103, and concrete is poured in the cavity 103 , so that the p...

Embodiment 2

[0057] The embodiment of the present invention provides the connection method of the connection system between the prefabricated laminated foundation and the fully prefabricated shear wall described in embodiment 1, such as Figure 1-2 As shown, the connection methods include:

[0058] S1: hoisting and positioning the precast concrete composite foundation 100 on a flat ground.

[0059] The prefabricated concrete composite foundation is transported, hoisted and positioned after being prefabricated in the factory. Before the foundation is installed, the ground at the bottom of the prefabricated foundation should be ensured to be flat. Because the precast concrete composite foundation has a cavity, it can greatly reduce its own weight, which is beneficial to the transportation, installation and positioning of the precast concrete composite foundation, and has lower requirements for hoisting equipment, which is convenient for construction.

[0060] S2: Hoist the fully prefabricat...

Abstract

The invention discloses a connecting system and a connecting method for a prefabricated composite foundation and a full-prefabricated shear wall, and belongs to the field of prefabricated buildings. The prefabricated concrete composite foundation comprises a peripheral wall protecting plate and at least one inner partition plate arranged in the peripheral wall protecting plate, wherein the inner partition plate divides the inner part of the peripheral wall protecting plate into a plurality of cavities; a positioning groove is formed in the top of each inner partition plate; reserved longitudinal ribs are arranged on the bottom of the full-prefabricated shear wall; the bottom edge of the full-prefabricated shear wall is blocked into the positioning grooves; the reserved longitudinal ribs are inserted into the cavities; and concrete is poured into the cavities, so that the prefabricated concrete composite foundation and the full-prefabricated shear wall are connected into an integer. Theconnecting system solves the problems that the prefabricated concrete foundation is too great in dead weight, foundation reserved lap joint reinforcing steel bars are difficult to position, precisionrequirements are high and the like in transportation, hoisting and connecting processes; and concrete construction does not need to support a template, a scaffold and the like, so that efficiency ishigh, and quality is guaranteed.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a connection system and method for a prefabricated laminated foundation and a fully prefabricated shear wall. Background technique [0002] In the traditional construction method, the cast-in-place concrete foundation and the cast-in-place shear wall are connected by the method of on-site wet pouring. This method has many wet operations on site, requires formwork support and demolition, serious pollution, long construction period and high cost. [0003] In order to reduce on-site wet work and reduce the use of on-site formwork as much as possible, prefabricated buildings came into being. The concrete foundation and shear wall are prefabricated in the factory, and then transported to the construction site for hoisting and installation, which can greatly reduce the use of on-site formwork or even omit the on-site formwork. The prefabricated concrete foundation of the existi...
