Embodiment 1

[0031] The structure of the on-site multi-directional force detection device of this embodiment is as follows: figure 1 As shown, the detection device includes an auxiliary supporting tool 1, two loading devices, two controllers, a specimen fixing device 5 and two displacement measuring devices.

[0032] The auxiliary support tooling 1 includes three frames, the frames are rectangular, made of steel, and have the strength to meet the testing requirements. Both the first frame 101 and the second frame 102 are perpendicular to the horizontal ground, the third frame 103 is parallel to the horizontal ground, and the third frame 103 is arranged above the second frame 102 . The second frame 102 is used to support the first loading device 2, and the third frame 103 is used to support the second loading device 201, so that the two loading devices can apply forces in both vertical and horizontal directions to the test piece simultaneously or step by step, At the same time, the first f...

Embodiment 2

[0043] The structure of the on-site multi-directional force detection device of this embodiment is as follows: figure 2 As shown, the main building structure of this embodiment is placed horizontally and the test piece is located on the side of the main building structure, the first frame 101 and the second frame 102 are respectively stuck on the upper and lower sides of the main building structure, and the third frame 103 is mounted on the building main structure. side of the main structure. The test piece fixing device 5 is placed vertically, the pendant 502 is upward, and the fixed bracket 501 is downward. The pendant 502 can be connected to the test piece on the side of the building main structure, and the second loading device 201 on the third frame 103 applies a vertical load. The first loading device 2 on the second frame 102 applies a load in the horizontal direction. The lower part of the fixing frame 104 is completely retracted into the first frame 101 .

Abstract

The invention provides an on-site multi-directional force detection device of a prefabricated building envelope connection system. Displacement measurement device, the auxiliary supporting tool has at least two mutually perpendicular frames, each frame is provided with a loading device, each loading device is connected to a controller, and each loading device is connected to the specimen fixing device through a dowel bar One end of the test piece fixing device is connected to the tested piece; the frame of the auxiliary support tooling is installed on the building main structure of the tested piece, and the test piece fixing device is arranged inside the frame of the auxiliary supporting tooling, The displacement measuring device is connected to the tested piece and the controller, quantitatively detects the displacement data of the tested piece and sends it to the controller, and the controller analyzes and draws the load-displacement curve.

Description

technical field [0001] The invention belongs to the technical field of on-site detection equipment for construction engineering, and in particular relates to an on-site multi-directional force detection device for a connection system of an assembled building envelope. Background technique [0002] With the development of my country's construction technology, unitized curtain walls and prefabricated buildings have gradually become the development trend of new modern buildings. They are the building systems with the highest technical content and relatively short construction period in my country and even the world, and their usage is increasing. For unitized curtain walls, the connection between its load-bearing structure system and the main structure of the building is usually achieved through prefabricated embedded parts or post-installed anchors. In addition to bearing the load of its own weight, the curtain wall also bears the influence of loads such as wind force and eart...
