Constructional lightgage steel joist and fitting one-piece test apparatus

Abstract

The invention discloses a constructional lightgage steel joist and fitting one-piece test apparatus. The apparatus comprises a plurality of support legs, the top portions of the support legs are provided with a rectangular frame, a first hoisting motor, a load-carrying hoisting motor, a second hoisting motor and a third hoisting motor are successively arranged above the rectangular frame, the rectangular frame is provided with one side-edge beam parallel with the first short edge of the rectangular frame, the first short edge and the side-edge beam are provided with a plurality of locking holes, the side-edge beam is connected with the long edge of the rectangular frame through an adjustment fixation hole, the adjustment fixation hole comprises a first long circular hole, a second long circular hole and a third long circular hole which are successively arranged at the long edge, the rectangular frame is also provided with at least two bearing crossbeams in parallel arrangement, one side surface of each bearing crossbeam is also provided with a hanging plate, and an erection hole is arranged in the middle of each hanging plate. The apparatus provided by the invention is simple in structure and convenient to operate, and has quite accurate detection data.

Description

technical field [0001] The invention relates to the field of building detection, in particular to an integrated test device for light steel keels and accessories for buildings. Background technique [0002] With the rapid development of the construction industry, new building materials are constantly emerging. As a new building material, light steel keel has the characteristics of high standardization, flexible space layout, good seismic performance, industrial production, short construction period, environmental protection and energy saving. , more and more widely used in various architectural structures. [0003] The light steel keel is a cold-formed thin-walled metal skeleton for construction, which is made of high-quality continuous hot-dip galvanized sheet and rolled by cold-bending process. It is used to make paper gypsum board, decorative gypsum board and other light boards. Facing of non-load-bearing walls and molding decoration of building roofs. Since the light s...

Problems solved by technology

[0004] Although the national standard "Light steel keel for construction" GB / T11981 gives the assembly schematic diagram of the mechanical performance test of the wall keel and the assembly diagram of the mechanical performance test of various ceiling keels, the industry standard "Light steel keel accessories for construction" JC / T558 gives the assembly schematic diagram of the mechanical performance test of light steel keel fittings. Some testing institutions have also made simple test devices according to the above schematic diagram, but there are the following deficiencies: First, the existing wall keel mechanical performance test device is simple. The quadrilateral frame is equipped with four short legs. Due to the low height of the overall test device, after the wall keel is installed in place, the dial indicator needs to be installed on the bottom of the wall keel by lying on the ground manually. The readings bring a lot of inconvenience; second, when carrying out the impact resistance test of the wall keel, it is necessary to manually carry a 60 kg sandbag and lower it at 30cm above the wall keel, and manual operation cannot guarantee the distance. The error is large, the accuracy of the test result is poor, and because the sandbag needs to be placed manually, the height of the workbench cannot be raised, and the operation is time-consuming and laborious; third, the mechanical performance test of the wall keel, the mechanical performance test of the ceiling keel and the mechanical performance of accessories are currently being carried out. The three devices in the test are independent, and the three devices need to be operated separately during the test, and the three devices occupy a large area
