Embodiment 1

[0029] Embodiment 1: This embodiment aims to provide a prefabricated lightweight partition wall strip connection device using double dovetail connections, which is mainly used for the combined assembly and installation of lightweight partitions. In view of the defects existing in the existing structure, As a result, after the installation of the lightweight partition is completed, it is easy to generate a gap between the two panels, which is troublesome to use and cannot be replaced twice. Based on this, this embodiment connects two or more sets of lightweight partitions through double dovetail connectors. The effective and reliable connection of the wall battens increases the necessary constraints to form an integral wall. Because the relative deformation between the two lightweight partition wall slabs is limited, it can effectively avoid the decrease of connection durability and overall stability caused by mortar cracking, and the construction of the connection is simple, av...

Embodiment 2

[0034]Embodiment 2: This embodiment is basically the same as Embodiment 1, and the difference is that this embodiment further limits the structure of the connector.

[0035] This example Figure 3-4 As shown in , wherein the connector 2 includes a driving arm 4 and a driving structure, the middle parts of the two driving arms 4 are hinged together through the main hinge shaft 5, and a driving structure that forces them to expand is arranged between the two driving arms 4; specifically for the above purpose , the moving structure includes a baffle and an air bag; the baffle is correspondingly arranged inside the driving arm, and an air bag cavity is formed between the driving arm, and the air bag is arranged in the air bag cavity, and when the air bag is filled with gas, it can expand to drive the arms spread out.

[0036] Specifically, the inner side of the baffle is set as an inclined plane. In order to further improve the driving effect of the airbag, the airbag has a figur...

Embodiment 3

[0038] Embodiment 3: This embodiment is basically the same as Embodiment 2, the difference is that this embodiment provides a second implementation of the driving structure.

[0039] Such as Figure 5-6 As shown, the second embodiment is: the drive structure includes a power arm 8 and a drive rod; the outer ends of the two power arms 8 are hinged at the outer ends of the drive arm 4, and the inner ends of the two power arms 8 are hinged together through the auxiliary hinge shaft 9 , the driving rod comprises a driving sleeve 10, a left connecting rod 13 and a right connecting rod 12, the two ends of the driving sleeve 10 are threadedly connected to the inner ends of the left connecting rod 13 and the right connecting rod 12, and the left connecting rod 13 and the Right connecting rod 12 threads are arranged in the opposite direction; the outer ends of left connecting rod 13 and right connecting rod 12 are respectively fixed on the main hinge shaft 5 and the auxiliary hinge sha...

Abstract

The invention belongs to the technical field of building technology, and specifically discloses an assembled light-weight partition wall panel connecting device adopting double dovetail connection. A connecting piece for connecting lightweight partitions; the outer end of the connecting groove is open, and the inner diameter is smaller than the inner end, thereby forming a dovetail structure with two pressing slopes; the connecting piece is matched and sleeved in the connecting groove, And it can compress the pressing inclined surface, so that the lightweight partitions are close to each other; it greatly reduces the difficulty of operation, and the installation can basically be completed by 1-2 people. The construction difficulty coefficient is low, and the construction time and construction workload can be greatly reduced. Improve construction efficiency, and can easily realize secondary demolition at the same time.

Description

technical field [0001] The invention belongs to the technical field of building technology, and in particular relates to an assembled light-weight partition wall strip connection device adopting double dovetail connection. Background technique [0002] The prefabricated structure refers to the architectural structure in which various components of the house are manufactured through factory mass production, and the components are transported to the construction site for assembly. Prefabricated buildings have unique advantages such as reducing labor intensity, reducing the amount of on-site concrete pouring, reducing construction waste, reducing construction noise, improving the construction environment, and reducing construction costs. It is in line with the green, energy-saving, and environmentally friendly building development policies advocated by the state. It greatly improves the construction efficiency and realizes the sustainable development of the building structure. ...
