Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a non-connected magnetic repulsion type deformation joint cover plate. Background Technique

[0002] During the construction of building engineering, due to the influence of temperature change, uneven settlement of the foundation and seismic factors, the building is prone to deformation or damage. Therefore, during design, the building is generally divided into several independent parts to enable each part to change freely and independently. This reserved joint that vertically separates the building is called a deformation joint. A deformation joint is a structural joint reserved for the situation where the building deforms under the action of external factors, resulting in cracking or even damage. A deformation joint is the general term for an expansion joint, a settlement joint, and a seismic joint. Under the action of external factors, the building often deforms, leading to cracking or even damage, and the deformation joint is exactly a structural joint reserved for such a situation to avoid the influence caused by deformation.

[0003] The building deformation joint must be connected and protected, and generally must also meet certain waterproof, heat preservation or decoration conditions. Therefore, a building deformation joint connection and protection device is required to cover and connect and protect the deformation joint. The treatment of the deformation joint of the concrete structure usually sets a deformation joint cover plate structure on the upper part of the structure. At present, most of the cover plate structures adopt rigid structures. When the deformation joint deforms, the cover plate structure is prone to deformation and damage, resulting in a gap between the cover plate structure and the deformation joint, and it is easy to出现 problems such as unstable connection or even damage, causing water seepage hazards. In addition, most of the existing building expansion joint structures do not have fireproof and flame-retardant properties, and these problems need to be improved urgently. Content of the Utility Model

[0004] In view of the above problems existing in the prior art, the main purpose of the present utility model is to provide a non-connected magnetic repulsion type deformation joint cover plate with fireproof and flame-retardant properties and waterproof and heat preservation properties.

[0005] To achieve the above purpose, the technical solution adopted by the present utility model is: a non-connected magnetic repulsion type deformation joint cover plate, comprising a base and a cover body;

[0006] The base includes Z-shaped stainless steel plates symmetrically embedded in the concrete on both sides of the deformation joint gap. A card slot is provided on one side of the vertical wall of the Z-shaped stainless steel plate near the top; a first permanent magnet is provided in the card slot, and the cross arm of the Z-shaped stainless steel plate close to the cover body is higher than the concrete plane on both sides of the deformation joint gap;

[0007] The cover body includes an inverted U-shaped plate and a rubber bearing seat. The rubber bearing seat and the inverted U-shaped plate are fixedly connected through a fastening structure. A card slot is provided on the side of the rubber bearing seat away from the inverted U-shaped plate and close to the Z-shaped stainless steel plate, and a second permanent magnet is provided in the card slot, and the magnetic pole direction of the second permanent magnet is the same as that of the first permanent magnet.

[0008] Furthermore, the fastening structure includes at least one inner screw hole arranged on the top of the rubber load-bearing seat, corresponding to a through hole arranged on the inverted U-shaped plate, and a bolt passing through the through hole and screwed into the inner screw hole.

[0009] Preferably, the inner threaded hole is a non-through threaded hole.

[0010] Furthermore, the slot is a C-shaped slot or a rectangular slot arranged along the length direction of the Z-shaped stainless steel plate.

[0011] Furthermore, a fire barrier strip is provided at the deformation joint between two relatively arranged Z-shaped stainless steel plates.

[0012] Furthermore, the width of the inverted U-shaped plate is greater than the sum of the widths of the two Z-shaped stainless steel plates, and the inverted U-shaped plate is buckled on the tops of the two Z-shaped stainless steel plates to prevent rainwater from penetrating.

[0013] Furthermore, the inverted U-shaped plate is made of stainless steel.

[0014] Compared with the prior art, the beneficial effect of the utility model is that the permanent magnet on the rubber load-bearing seat has the same magnetic pole direction as the permanent magnet on the Z-shaped stainless steel plate, and the permanent magnet on the rubber load-bearing seat and the permanent magnet on the Z-shaped stainless steel plate are staggered in height. Since like poles repel each other, when the cover is installed between the two Z-shaped stainless steel plates, the rubber load-bearing seat will be squeezed by the repulsive force of the permanent magnets on both sides, and can be placed on the base in a non-connected manner and remain stable. After the deformation joint is deformed, it is automatically adjusted to a balanced state under the action of the repulsive force of the permanent magnet, and can be both fire-retardant and waterproof and heat-insulating.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Example

[0019] As Figure 1 , 2 shown, a non-connected magnetic repulsion type deformation joint cover plate includes a base 1 and a cover body 2;

[0020] The base 1 includes Z-shaped stainless steel plates 1001 symmetrically embedded in the concrete on both sides of the deformation joint gap. On one side of the vertical wall of the Z-shaped stainless steel plate 1001 near the top, there is a card slot 3, and the card slot 3 is a C-shaped groove arranged along the length direction of the Z-shaped stainless steel plate 1001; a first permanent magnet 4 is arranged in the card slot 3. The cross arm of the Z-shaped stainless steel plate 1001 close to the cover body 2 is higher than the concrete plane on both sides of the deformation joint gap, which can prevent rainwater or accumulated water from seeping into the deformation joint from the top of the Z-shaped stainless steel plate 1001;

[0021] The cover body 2 includes an inverted U-shaped plate 2002 and a rubber bearing seat 2003. The rubber bearing seat 2003 and the inverted U-shaped plate 2002 are fixedly connected through a fastening structure 2001. On the side of the rubber bearing seat 2003 away from the inverted U-shaped plate 2002 and close to the side of the Z-shaped stainless steel plate 1001, there is a card slot 3, and a second permanent magnet 5 is arranged in the card slot 3, and the magnetic pole direction of the second permanent magnet 5 is the same as that of the first permanent magnet 4;

[0022] Since the magnetic pole direction of the second permanent magnet 5 on the rubber bearing seat 2003 is the same as that of the first permanent magnet 4 on the Z-shaped stainless steel plate 1001, and the second permanent magnet 5 on the rubber bearing seat 2003 is height-displaced from the first permanent magnet 4 on the Z-shaped stainless steel plate 1001. According to the principle of like poles repelling and opposite poles attracting, it can be determined that when the cover body 2 is installed between two Z-shaped stainless steel plates 1001, the rubber bearing seat 2003 will be repelled and squeezed by the permanent magnets on both sides, and can be placed on the base 1 in a non-connected manner and remain stable. After the deformation joint deforms, the distance between the permanent magnet on the Z-shaped stainless steel plate 1001 and the permanent magnet on the rubber bearing seat 2003 changes. Affected by the repulsive force of the permanent magnet, the rubber bearing seat 2003 can automatically adjust to a balanced state under the action of the repulsive force of the permanent magnet.

[0023] The fastening structure 2001 includes an internal thread hole arranged at the center of the top of the rubber bearing seat 2003, a through hole arranged at the center of the inverted U-shaped plate 2002, a bolt screwed through the through hole and into the internal thread hole, and a rainproof cap is arranged on the bolt.

[0024] The internal thread hole on the rubber bearing seat 2003 is a non-through threaded hole.

[0025] A fireproof belt 6 is arranged at the deformation joint between two relatively arranged Z-shaped stainless steel plates 1001.

[0026] The width of the inverted U-shaped plate 2002 is greater than the sum of the widths of the two Z-shaped stainless steel plates 1001 . The inverted U-shaped plate 2002 is buckled on the tops of the two Z-shaped stainless steel plates 1001 to prevent rainwater from penetrating.

[0027] The material of the inverted U-shaped plate 2002 is stainless steel.

[0028] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the utility model.
