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 connection system and a connection method of a prefabricated composite foundation and a fully prefabricated shear wall, belonging to the field of prefabricated buildings. The prefabricated concrete composite foundation includes an outer wall panel and at least one inner partition arranged in the outer wall panel. The inner partition divides the interior of the outer wall panel into several cavities. Groove; the bottom of the fully prefabricated shear wall is provided with reserved longitudinal reinforcement, the bottom edge of the fully prefabricated shear wall is stuck in the positioning groove, the reserved longitudinal reinforcement is inserted into the cavity, and concrete is poured in the cavity, so that the precast concrete The composite foundation is connected with the fully prefabricated shear wall as a whole. The invention solves the problems of the prefabricated concrete foundation in the process of transportation, hoisting and connection due to the excessive self-weight and the difficulty in positioning the lapped steel bars reserved for the foundation and high precision requirements; the concrete construction does not need to support formwork, scaffolding, etc., and the efficiency is high and the 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...
