[0002] When a house is being built, it needs to be reinforced with steel structures. The steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Since the steel structure determines the quality of the house, the steel structure needs to be pressure tested by a strength testing device before use.

[0003] Patent document CN218725236U discloses a device for detecting the connection strength of a steel structure of a house. When the strength detection device in the patent document is in use, the bracket can rotate along the deformation direction of the detection part through the rotating component, thereby avoiding affecting the detection result of the detection part and improving the accuracy of the steel structure strength detection. However, the strength detection device cannot adjust the distance between the supporting structures of the steel structure when in use, which makes it inconvenient to detect the steel structure under different reserved spaces. Utility Model Content

[0004] One purpose of the present application is to provide a device for detecting the connection strength of steel structures of a house, so as to solve the technical problem that the strength detection device proposed in the prior art cannot adjust the distance between the supporting structures of the steel structure during use, thereby making it inconvenient to detect the steel structure under different reserved spaces.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for detecting the connection strength of a steel structure of a house, comprising a detection box, a base frame installed at the bottom of the detection box, a support assembly symmetrically installed on the top of the base frame, the support assembly being used to support the steel structure, the support assembly comprising a support block, a slider and a positioning groove, the slider being installed at the bottom of the support block, a positioning groove being provided at the top of the support block, threaded sleeves being installed through both sides of the detection box, a threaded rod being installed on the internal threads of the threaded sleeve, and a rotating handle being installed at one end of the threaded rod.

[0010] Preferably, a mounting plate is installed at the detection end of the pressure detector, and a detection pressure plate is installed at the bottom of the mounting plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the present invention, the steel pipe is supported by the support block during testing. The distance between the support blocks is different, and the pressure value borne by the steel pipe is also different. In order to make the strength test data of the steel pipe connection more comprehensive, the support blocks can be slid so that the distance between them can be adjusted. When pushing and adjusting, the threaded rod is rotated by turning the handle to limit the support blocks at different distances, so that the support blocks can stably support the steel structure being tested. The scale line makes it easy to understand the distance between the support blocks.

A base frame 6 is installed at the bottom of the detection box 1, and a support assembly is symmetrically installed on the top of the base frame 6.

[0024] The inspection box 1 provides a location for installing the inspection structure of the steel structure, and the base frame 6 provides a location for installing the support assembly. The utility model is used to detect the connection strength of the steel pipe of the steel structure. The steel pipe is supported by the support block 9 during the inspection, and the distance between the support blocks 9 is different, and the pressure value borne by the steel pipe is also different. In order to make the data of the strength detection of the steel pipe connection more comprehensive, the support block 9 can slide so that the distance between them can be adjusted. When pushing and adjusting, the threaded rod 4 is rotated by turning the handle 5, so that the threaded rod 4 limits the support blocks 9 at different distances, so that the support block 9 can stably support the inspected steel structure. The scale line 8 makes it convenient to understand the distance between the support blocks 9.
