Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, specifically relating to a testing structure for non-expanding gypsum coatings. Background Technology

[0002] This is a coating specifically designed to improve the fire resistance of steel structures, primarily used for surface protection of load-bearing columns and beams in indoor steel structures. Thanks to its non-combustibility, low thermal conductivity, and excellent insulation properties, this coating effectively prevents fire from reaching steel structures, significantly extending their fire resistance time.

[0003] After non-intumescent fire retardant coatings are produced, they need to be tested to determine their expansion after spraying, so that a device can be produced to test them. Utility Model Content

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a test structure for non-expanding gypsum coating, including a base plate and side rails on both sides, wherein the side rails are fixedly arranged on the left and right sides of the base plate, characterized in that: side slide rails are provided on the front and rear sides of the base plate, and top slide rails are provided on the front and rear sides of the top of the base plate, and multiple material feeding structures are slidably arranged on the front and rear sides of the base plate corresponding to the side slide rails and top slide rails, respectively; a rotating shaft is rotatably arranged in the middle of the opposite side of the two side rails, and a sliding rod is inserted between the two rotating shafts; a scale is embedded in the surface of the sliding rod, and a first test plate and a second test plate are respectively arranged on the surface of the sliding rod corresponding to the material feeding structure; and a storage seat is provided on one side of the top of the base plate.

[0006] Preferably, the side guard is provided with lugs on both the left and right sides for storing the slide rod.

[0007] Preferably, the feeding structure includes a slide block, a side slide rail, a fixed clamping plate, a sliding clamping plate, and a slide frame. The bottom of the slide frame has a first slide groove corresponding to the top slide rail, and the side slide rail has a second slide groove corresponding to the side slide rail. The side slide rail is arranged on the front and rear sides of the slide block. The fixed clamping plate is fixedly arranged on one side of the top of the slide block, and the sliding clamping plate is arranged on the top of the slide block.

[0008] Preferably, the slide is disposed on one side of the bottom of the sliding clamp, and the left and right sides of the slide extend downward and are slidably connected to the side slide rail.

[0009] The beneficial effects of this utility model are as follows: By setting multiple material feeding structures on the front and back of the base plate respectively, and the material feeding structures are symmetrically arranged left and right, it can be used to place the plate to be sprayed, which is convenient for spraying. At the same time, multiple sets of material feeding structures are set to facilitate multiple sets of tests. The material feeding structure is achieved by the cooperation of fixed clamping plates and sliding clamping plates. The sliding clamping plates are slidably set by the sliding frame and the side sliding groove on the sliding base. The sliding frame limits the sliding clamping plates and facilitates sliding installation according to the thickness of the plate. By setting a rotating shaft between the two side blocks and a sliding rod between the two rotating shafts, a first test plate and a second test plate are slidably set on the sliding rod. The two test plates, together with the scale on the sliding rod, are used to test the thickness of the plate before and after the test, which is used to test the expansion of non-expanding gypsum coating after spraying. At the same time, by setting a storage seat on one side of the base plate, the plate can be stored after the test or before the test. Attached Figure Description
