Description

Technical Field

[0001] The utility model relates to the technical field of detecting the bonding strength of facing bricks, and more specifically, to a device for detecting the bonding strength of facing bricks. Background Technique

[0002] Detecting the bonding strength of facing bricks is a process of evaluating the bonding strength between the facing bricks used in a building and the substrate. This process is crucial for ensuring the appearance integrity and safety of the building, because the detachment of facing bricks may cause injuries and property losses.

[0003] Currently, when detecting the bonding strength of facing bricks, the traditional detection method generally involves connecting a standard part through a pulling structure, cutting a test piece on the facing brick that is adapted to the shape of the standard part, then aligning and pasting the standard part on the test piece, and then connecting the standard part through the pulling structure for pulling, so as to obtain the bonding strength data of the facing brick. The connection method between the traditional pulling structure and the standard part is that a connecting block is arranged at the center position on one side of the standard part, a circular groove is opened at the center position on the outer edge surface top of the connecting block, and a hole communicating with the circular groove is opened at the center of one end of the connecting block. The end of the pulling structure is provided with a clamping block, and the clamping block is clamped in the circular groove and the end of the pulling structure passes through the hole. This results in that when in use, if the clamping block is to be put into and taken out of the circular groove, the clamping block and the circular groove need to be in clearance fit, which causes a gap between the clamping block and the circular groove. It is not convenient to maintain the coaxiality between the clamping block and the circular groove during the pulling process, and thus the measured data has a certain error. In view of this, we propose a device for detecting the bonding strength of facing bricks. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a device for detecting the bonding strength of facing bricks, so as to solve the technical problem that the connection between the current traditional detection device and the test piece is a coaxial single connection, and the coaxiality is easily affected by the gap, resulting in errors in the measured data.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A device for detecting the bonding strength of facing bricks, comprising a support component with a connection component movably installed inside and a standard part component detachably connected to the connection component;

[0006] The support component includes a U-shaped seat with a lead screw component rotatably installed inside;

[0007] The connection component includes a connection block with a through hole centrally opened inside. The connection block is movably connected to the lead screw component, and convex blocks are arranged in an annular array structure on the outer edge surface of the connection block. A shaft hole is opened inside the convex block, and a connection component is movably installed in the shaft hole;

[0008] The connecting component includes a round block with connecting arms constructed at both ends. Both ends of the connecting arms are constructed with pulling blocks. A connecting structure that is movably connected to the shaft hole is detachably installed in the middle of the connecting arm, and a torsion spring is arranged between the connecting arm and the connecting structure;

[0009] The standard part assembly includes a standard part body with a pulling block constructed in the middle on one side. On the outer edge surface of one end of the pulling block facing the standard part body, pulling grooves adapted for the pulling blocks to be snap-fitted are arranged in an annular array.

[0010] Preferably, an embedded card slot is recessed inward from one side of the inner wall of the pulling groove towards the pulling block. At the end of the pulling block away from the connecting arm, an embedded hook part is constructed for bending inward and adapting to the embedded card slot to form an embedded snap connection.

[0011] Preferably, a round hole is centrally opened inside the round block. The connecting structure includes connecting plates that are symmetrically and detachably arranged on the upper and lower end surfaces of the round block at one end, and the other ends of the connecting plates are detachably connected to the upper and lower end surfaces of the convex block.

[0012] Preferably, bolts are inserted into both the shaft hole and the round hole. The end of the bolt extends out of the connecting plate, and nuts for limiting the connecting plate are detachably arranged at both ends of the bolt.

[0013] Preferably, expansion guiding grooves for expanding and guiding the embedded hook parts so that they can be snapped into the embedded card slots are arranged in an annular array on the outer edge surface of the end of the pulling block away from the standard part body.

[0014] Preferably, an installation hole is centrally opened inside the U-shaped seat. The lead screw component includes a lead screw body with both ends respectively passing through the installation hole and the through hole. A sliding seat is movably engaged on the outer edge surface of the lead screw body. The sliding seat is fixedly installed in the through hole. A bearing is detachably arranged on the outer edge surface of one end of the lead screw body. The bearing is rotatably installed in the installation hole. The end of the lead screw body extending out of the U-shaped seat is constructed with a hexagonal prism block, and a grip rod is detachably inserted and installed inside the hexagonal prism block. A limiting ball head is constructed at one end of the grip rod.

[0015] Preferably, sector-shaped abutting plates are constructed at both ends of the U-shaped seat, and arc-shaped abutting strips are constructed on the outer edge surfaces of the sector-shaped abutting plates.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. The utility model designs a lead screw component, a connection component and a connection part. By arranging bumps in an annular array on the outer edge surface of the connection block, and movably installing the connection part in the shaft hole of the bump, the multi-claw clamping and pulling of the standard part body can be realized through the connection part by means of the clamping fit between the pulling block and the pulling groove. This is beneficial to ensuring that the pulling force is consistent with the axis of the bearing block and vertically points to the standard part body and the test piece, so that the standard part body and the test piece can be uniformly stressed, reducing the error of measurement data, and achieving the effect of improving the detection accuracy of the bonding strength of facing bricks. It solves the problem that the connection between the traditional detection device and the test piece is a coaxial single connection, and the coaxiality is easily affected by the gap, resulting in errors in the measurement data.

[0018] 2. The utility model also forms an embedded hook claw part at the end of the pulling block. An embedded clamping and grabbing structure can be formed by the embedded hook claw part and the embedded clamping groove. Cooperating with the multi-claw structure is beneficial to further ensuring the grabbing effect on the bearing block, realizing the uniform stress of the bearing block, thereby ensuring the accuracy of the measurement data, and further solving the problem that the connection between the traditional detection device and the test piece is a coaxial single connection, and the coaxiality is easily affected by the gap, resulting in errors in the measurement data.

[0028] As Figures 4 - 6 shown, in the embodiment of the present utility model, an embedded card slot 405 is opened by invading inward from one side of the inner wall of the tensile groove 404 towards the tensile bearing block 402.

[0031] Working principle: This embodiment provides a device for detecting the bonding strength of facing bricks. When in use, first, a corresponding test piece is cut on the facing brick according to the size of the standard part body 401. Then, an adhesive is coated on one side of the standard part body 401. Then, the standard part body 401 is bonded to the test piece. Then, the support assembly 1 is pushed to drive the connecting assembly 2 to move towards the tensile block 402, so that the embedded claw part 303 abuts against the expansion guide groove 403, and under the expansion guiding action of the expansion guide groove 403, the connecting arm 301 deflects, and at the same time, the torsion spring deforms. As the connecting assembly 2 moves, when the pulling block 302 and the embedded claw part 303 move to appropriate positions, under the elastic force of the torsion spring, the pulling block 302 and the embedded claw part 303 are respectively clamped into the pulling groove 404 and the embedded card slot 405, so that the connecting assembly 2 and the tensile block 402 complete coaxial grasping. Then, by holding the grip rod 108 and rotating, the lead screw body 105 rotates, so that the sliding seat 106 drives the connecting assembly 2 to move, so that the connecting member 3 applies a tensile force to the standard part assembly 4, forming a pulling effect, and realizing the detection of the bonding strength of the test piece.
