Description

Technical Field

[0001] The utility model relates to the technical field of floor construction, and in particular to a wear-resistant floor modular expansion joint. Background Art

[0002] The floor materials of modular wear-resistant flooring are easily affected by natural factors (such as temperature and humidity changes) and frequency of use, and are prone to cracking, cracking and warping due to internal stress in the floor materials. In order to prevent floor cracking and deformation, enhance the looseness of construction and transportation, adapt to ground settlement and vibration, and improve the aesthetics of floor construction, modular wear-resistant flooring components need to be expanded and contracted through expansion joints. The expansion joints allow the floor materials to have a certain amount of expansion and contraction space when heated and contracted, thereby preventing the occurrence of floor cracks and deformation.

[0003] Wear-resistant floor modular expansion joints, also known as split strips, crack strips or isolation strips, are rectangular strip components made of an elastic material (such as rubber or polyurethane).

[0004] However, the rectangular strip components in the existing expansion joints are complicated to install. When placed between two floors, both sides need to be bonded. Moreover, when the gap of the expansion joint is not uniform, the rectangular strip components may become loose between the two floors. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the rectangular strip components in the existing expansion joints are complicated to install and need to be bonded on both sides when placed between two floors. In addition, when the gap of the expansion joint is not uniform, the rectangular strip components may become loose between the two floors.

[0006] Therefore, based on the above-mentioned problem, the present invention proposes a wear-resistant floor modular expansion joint, including a buffer assembly provided between the floors, the buffer assembly consisting of an upper block at the top, a buffer cylinder in the middle, and a lower block connected at the bottom.

[0007] Preferably, a pressure relief groove is provided in the middle of the upper block, and R angles are provided on the left and right sides of the upper block respectively.

[0008] Preferably, a second pressure relief groove is provided in the middle of the buffer cylinder, the first pressure relief groove and the second pressure relief groove are interconnected, the buffer cylinder as a whole is circular, its diameter is the same as the R angle of the upper block, and the second pressure relief groove is also circular.

[0009] Preferably, an inserting block is fixedly bonded to the bottom of the lower block, the inserting block is arranged in a triangular shape, and the lower part of the inserting block is conical.

[0010] Preferably, the buffer component is made of polyurethane material, the insert block is made of rubber material, and the hardness of the buffer component is higher than that of the insert block.

[0011] Beneficial effect: Place the buffer assembly between two modular floors, then use force to embed the buffer assembly from top to bottom into the gap between the two floors. The insert will be deformed by pressure and placed at the bottom of the two floors. At the same time, the buffer cylinder in the middle of the buffer assembly will contact between the two floors. The combination of the deformable buffer cylinder and the insert will achieve a self-locking effect and adapt to the size of the floor expansion joint, allowing for rapid installation between the two floors. Moreover, since the interior of the buffer cylinder is circular and is provided with a second pressure relief groove, the buffer cylinder can perform a buffering effect on the floor through deformation, thereby preventing the occurrence of cracks and deformation of the floor due to thermal expansion and contraction. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a schematic diagram of the structure of the buffer component of the utility model;

[0014] Figures 1 to 2 The reference numerals are: floor 1, buffer assembly 2, upper block 201, buffer cylinder 202, lower block 203, insert block 3, pressure relief groove 1 4, pressure relief groove 2 401. DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Reference Figures 1 to 2 , a wear-resistant floor modular expansion joint, including a buffer component 2 provided between the floor 1 and the floor 1, the buffer component 2 prevents the floor material from cracking, cracking and warping due to changes in internal stress in winter and summer, the buffer component 2 is composed of an upper block 201, a buffer cylinder 202 in the middle, and a lower block 203 connected at the bottom. The buffer component 2 is placed between the two modular floors 1, and the width of the buffer cylinder 202 of the buffer component 2 is larger than the gap between the floors 1. Then, the buffer component 2 is forcefully embedded in the gap between the two floors 1 from top to bottom, and then the buffer component 2 is pressed. The rubber insert 3 at the bottom of the buffer component 2 will be deformed by pressure and placed at the bottom of the two floors 1. Then, as the buffer component 2 continues to be pressed downward, the buffer cylinder 202 in the middle of the buffer component 2 will contact between the two floors 1, first deform, flatten and support outward. Since a pressure relief groove 2 401 is opened in the middle of the buffer cylinder 202 and it is made of polyurethane material, partial deformation will occur, causing it to be stuck between the floors 1.

[0017] Preferably, a pressure relief groove 4 is provided in the middle of the upper block 201, and R angles are provided on the left and right sides of the upper block 201. Since the R angles of the upper block 201 are extended outward, a self-locking effect can be achieved by cooperating with the outward-deformable buffer cylinder 202 and the insert block 3.

[0018] Preferably: a pressure relief groove 2 401 is opened in the middle of the buffer cylinder 202, and the pressure relief groove 1 4 is connected to the pressure relief groove 2 401. The buffer cylinder 202 is designed as a circle as a whole, and its diameter is the same as the R angle of the upper block 201. The pressure relief groove 2 401 is also designed as a circle. When the floor 1 causes cracks and deformation due to thermal expansion and contraction, the gap between the buffer cylinder 202 and the upper block 201 can be expanded and contracted between the pressure relief groove 1 4 and the pressure relief groove 2 401, thereby playing a buffering role and adapting to the size of the expansion joint.

[0019] Preferably, an insert block 3 is fixedly bonded to the bottom of the lower block 203. The insert block 3 is triangular in shape, and the lower portion of the insert block 3 is tapered. When the insert block 3 reaches the bottom of the two floor plates 1, the tapered bottom portion of the insert block 2 facilitates intermittent insertion between the floor plates 1, and the triangular shape of the insert block 3 can effectively prevent the buffer assembly 2 from being lifted up due to the internal stress between the two floor plates 1.

[0020] Preferably, the buffer component 2 is made of polyurethane material, the insert block 3 is made of rubber material, and the material hardness of the buffer component 2 is higher than the material hardness of the insert block 3.

[0021] Working principle:

[0022] When in use, place the buffer component 2 between the two modular floors 1, then use force to insert the buffer component 2 from top to bottom into the gap between the two floors 1, and then press the buffer component 2. The rubber material plug 3 at the bottom of the buffer component 2 will be deformed by pressure and placed at the bottom of the two floors 1. Then, as the buffer component 2 continues to press down, the buffer cylinder 202 in the middle of the buffer component 2 will contact between the two floors 1, and will first deform, become flat and stretch outward. Since the middle of the buffer cylinder 202 is provided with a pressure relief groove 2 401 and is made of polyurethane material, a partial The deformation causes it to be stuck between the floor 1. At the same time, the upper block 201 on the top of the buffer component 2 will also fit together with the R angle of the upper part of the floor 1. Since the R angle of the upper block 201 is extended outward, the combination of the deformable buffer cylinder 202 and the plug block 3 will achieve a self-locking effect and adapt to the size of the floor expansion joint, thereby achieving rapid installation. Moreover, since the interior of the buffer cylinder 202 is set to be circular and is provided with a pressure relief groove 401, the buffer cylinder 202 can buffer the floor 1 through deformation, thereby preventing the floor 1 from cracking and deformation due to thermal expansion and contraction.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
