Description

Technical Field

[0001] The utility model relates to the technical field of wall finishing layer testing, in particular to a wall finishing layer tensile strength standard block connecting device. Background Art

[0002] The main functions of the wall finishing layer are to beautify the appearance of the building, protect the wall base from damage and waterproof, etc. The finishing layer can be divided into a variety of materials, including but not limited to facing stone, facing bricks, wall mortar, etc. These materials need a common characteristic, that is, they are not easy to fall off. In order to test this characteristic, the tensile strength test needs to be carried out after the wall finishing layer is completed.

[0003] For example, the utility model with application number CN201520189488.7 discloses a standard plastic test block for the tensile strength of exterior wall facing tiles, comprising a bonding base, a puller screw connection seat, screw holes, and stiffening ribs. The bonding base, the puller screw connection seat, screw holes, and stiffening ribs are made of high-strength plastic by one-time injection molding. The bottom of the bonding base is provided with a bonding surface. The puller screw connection seat is arranged at the top center of the bonding base. The puller screw connection seat is a cylinder protruding from the top plane of the bonding base. One end of the puller screw connection seat is connected to the bonding base by an arc transition. The screw hole is radially arranged in the middle of the puller screw connection seat. The product has a simple structure and ingenious design. Since the test block now uses improved plastic as raw material, the whole is formed in one time and no additional processing is required.

[0004] Similar to the above application, there are still the following deficiencies:

[0005] The connection method of the existing wall tensile strength standard blocks is a single-point threaded connection. The threaded connection process is cumbersome and time-consuming. The threaded connection is usually a nut welded on the standard block, and the stress point is only the position of the nut. During the welding process, the nut is prone to tilt, resulting in uneven force during the tensile process, which has a great impact on the test results.

[0006] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a sample cabinet structure is proposed. Utility Model Content

[0010] By providing the clamping connection between the convex groove and the concave groove, the preparation time before the detection can be shortened and the accuracy can be improved.
