Embodiment 1

[0046] refer to figure 1 , Embodiment 1 of the present application discloses a prefabricated component connection device, including a clamping part 1 and a locking part 2, and the prefabricated component connection device is mainly used for vertical connection of prefabricated components.

[0047] refer to figure 2 , the lower surface of the clamping piece 1 abuts against the upper surface of the locking piece 2, and the clamping piece 1 is used to clamp the overhanging steel bar of the upper component, so that the connecting device is fixedly connected with the upper component; the locking piece 2 can pass through The outstretched steel bars of the lower component are locked in a thread fit manner, so that the connecting device is fixedly connected with the lower component.

[0048] refer to figure 1 , in this embodiment, the lower part of the locking member 2 is a regular hexagonal prism, which is convenient for screwing operation during screw connection. In other embodim...

Embodiment 2

[0057] refer to Figure 5 and Image 6 The difference between this embodiment and Embodiment 1 is that the upper surface area of ​​the accommodating groove 11 is larger than the lower surface area, the inclination direction of the side wall of the accommodating groove 11 changes, and the surface of the clamping block 12 matched with the side wall of the accommodating groove 11 The direction of inclination also changes accordingly; and the upper part of the fixed column 231 is uniformly inclined to the direction away from the axis of the mounting hole 21. Correspondingly, the inclination direction and angle of inclination of the oblique hole 121 need to be consistent with the fixed column 231, so it also follows the direction of the fixed column. 231 is changed; and in this embodiment, the initial position of the clamping block 12 is at the upper part of the accommodating groove 11 , and the upper surface of the clamping block 12 is flush with the upper surface of the clamping ...

Embodiment 3

[0060] refer to Figure 7 and Figure 8 , The difference between this embodiment and Embodiment 1 is that the depth of the locking groove 22 gradually increases along the direction approaching the mounting hole 21 . The design of the locking groove 22 in this embodiment can reduce the contact area between the locking member 2 and the positioning portion 13 compared with the first embodiment, and the frictional force is correspondingly reduced, which is beneficial to the rotation of the clamping member 1 .

[0061] refer to Figure 9 , the present application discloses a prefabricated component assembly, including a first component 3, a second component 4, and the prefabricated component connecting device as in Embodiment 1. The first component 3 is located on the upper part of the entire assembly, and the bottom of the first component 3 has a partially protruding first steel bar 31. The integrity with the first member 3 is strong, and the force is continuous. The first ste...

Abstract

The invention relates to the technical field of prefabricated buildings, and particularly relates to a prefabricated part connecting device, a prefabricated part assembly and an assembling method. The prefabricated part connecting device comprises a locking piece and a clamping piece; the locking piece is provided with a mounting hole with an internal thread, a locking groove is formed in the side face of the locking piece in a surrounding mode, and the clamping piece is provided with a positioning part which is in rotary fit with the locking groove; the clamping piece is provided with a containing groove, the side wall of the containing groove is an inclined arc surface, two or more clamping blocks are arranged in the containing groove, and the clamping blocks are arranged in the circumferential direction of the inner wall of the containing groove and are in threaded fit with the inner wall of the containing groove; and limiting pieces which are in one-to-one correspondence with the clamping blocks are fixedly connected to the locking piece, and the limiting pieces are in sliding fit with the clamping blocks so that the clamping blocks and the side wall of the containing groove can do relative spiral movement. According to the prefabricated part connecting device, dry type connection of prefabricated parts can be realized, the operation is simple and convenient, the influence of weather on installation is small, the efficiency can be improved, and the construction period can be shortened.

Description

technical field [0001] The present application relates to the technical field of prefabricated buildings, in particular to a prefabricated component connecting device, a prefabricated component assembly and an assembly method. Background technique [0002] The prefabricated building refers to the construction method in which the building components are prefabricated in the factory and transported to the site for installation and assembly. Prefabricated buildings meet the requirements of building industrialization and green environmental protection, and the construction speed is fast, less affected by the weather, and the demand for on-site labor is small. It is a convenient and environmentally friendly construction method. [0003] In order to ensure the structural strength and connection strength of prefabricated components, steel bars are usually used as the stress tendons of its internal skeleton. Prefabricated component steel bars are usually connected by sleeve connect...
