Description

Technical Field

[0001] The utility model belongs to the technical field of building construction accessories, in particular to an anti-seismic beam clamp and a connection structure. Background Art

[0002] Beam clamps are tools that are usually used to clamp and fix the flanges of beams and columns to facilitate subsequent processing, assembly, transportation and other operations. In the construction industry, beam clamps are used to clamp and fix various beams and columns, such as beams of buildings such as houses, bridges, and buildings. The use of beam clamps can make the installation of beams more convenient and stable, and improve the stability and safety of buildings.

[0003] In the prior art, for example, in steel structures in the construction industry, a U-shaped beam clamp is commonly used. When in use, the U-shaped beam clamp bites the flange of the steel section by the friction between the edge and the surface, or bites and fixes with the flange of the steel column. However, when the U-shaped beam clamp vibrates back and forth in a certain horizontal direction, the bite point is prone to loosening, so the seismic performance of the U-shaped beam clamp is poor.

[0004] In addition, in the steel structure of the construction industry, the more common casting triangular beam clamps are also called triangular beam clamps for short. Triangular beam clamps are mostly used in environments with high requirements for seismic performance, but triangular beam clamps are mostly castings. In the production process, furnace casting is usually used for batch production to reduce production costs, but this will lead to inventory backlogs due to too many production quantities and increase product costs. In addition, some businesses use individual production methods for casting, but this will greatly increase production costs, and whether it is batch production or individual production, the production efficiency is relatively low.

[0005] Therefore, it is necessary to improve the above defects, and thus it is necessary to propose a seismic beam clamp and a connection structure thereof. Utility Model Content

[0006] The utility model provides an anti-seismic beam clamp and a connection structure to solve the problem that the anti-seismic performance of the beam clamp is poor during use.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model discloses an anti-seismic beam clamp, comprising an outer clamp and an inner clamp arranged in a U shape;

[0009] The inner clamp is arranged on the inner side of the outer clamp and abuts against the inner side surface of the outer clamp;

[0010] The inner clamp and the outer clamp are provided with through-type clamping grooves for placing the clamped objects on both side arms; a through-type pressure block is installed at the lower part of the clamping groove, and a fixing piece is threadedly installed on the surface of the pressure block for applying pressure to the clamped object in the clamping groove upward for movable adjustment, and the longitudinal direction of the fixing piece is set at an acute angle to the opening direction of the clamping groove.

[0011] Furthermore, the inner clamp and the outer clamp are both provided with through holes, and the through holes are adapted to the pressing blocks.

[0012] Furthermore, the fixing member adopts a pointed torsion shear bolt, and when the required torque is reached during installation, the hexagonal head will be twisted off and fall off.

[0013] Furthermore, the pressing block is provided with an adjustment hole, and the fixing piece is arranged through the adjustment hole.

[0014] Furthermore, an anti-slip pattern is provided on the inner wall of the clamping groove on the side away from the fixing member, which is used to increase the friction between the clamped object and the clamping groove; the anti-slip pattern is an isosceles trapezoidal convex point or sharp point, and the anti-slip pattern is used to increase the friction between the clamped object and the clamping groove.

[0015] Furthermore, the opening width of the clamping groove is 6-31 mm, which is divided into two models: 6-19 mm and 16-31 mm.

[0016] Furthermore, the outer clamp includes an outer connecting plate and outer clamps arranged on both sides of the outer connecting plate, and the outer connecting plate is integrally connected to the outer clamp; the inner clamp includes an inner connecting plate and inner clamps arranged on both sides of the inner connecting plate, and the inner connecting plate is integrally connected to the inner clamp.

[0017] Furthermore, both the outer connecting plate and the inner clamping plate are provided with connecting square holes, and the connecting square holes are provided with connecting pieces, and the connecting pieces are used to be connected to the seismic-resistant connecting pieces.

[0018] A connection structure includes the above-mentioned anti-seismic beam clamp, and the connection structure also includes a steel beam, the flange of the steel beam is adapted to the clamping groove, and the fixing piece abuts and bites against the flange of the steel beam.

[0019] Furthermore, the connection structure also includes a seismic connector and a channel steel; one end of the seismic connector is provided with a connecting hole, and the connecting hole is used for connecting the seismic beam clamp and the seismic connector; the other end of the seismic connector is fixedly connected to one end of the channel steel, and the other end of the channel steel is used to connect to a power source.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] The seismic beam clamp and connection structure of the present technical solution include a pressure block, a fixing member, an inner clamp and an outer clamp, and clamping grooves arranged on the inner clamp and the outer clamp. By adjusting the placement angle of the pressure block, the lateral direction of the pressure block is set at an acute angle with the opening direction of the clamping groove for placing the clamped object. At the same time, the longitudinal direction of the fixing member intersects with the opening direction of the clamping groove at an acute angle. Therefore, when the fixing member bites and fixes the clamped object in the clamping groove, the clamped object is subjected to a force opposite to the opening of the clamping groove, thereby increasing the bite stability of the utility model on the clamped object, thereby improving the earthquake resistance of the utility model, and greatly improving the seismic performance of the beam clamp during use.

[0033] like Figures 1 to 5 As shown, the utility model discloses an anti-seismic beam clamp, including an outer clamp 10 and an inner clamp 20, both of which are formed by bending 6mm thick Q235B or above grade plates and are both arranged in a U shape, wherein the inner clamp 20 is arranged on the inner side of the outer clamp 10 and abuts against the outer clamp 10, and the outer clamp 10 and the inner clamp 20 are provided with a clamping groove 21 for placing a clamped object, and the inner wall width of the clamping groove 21 is 6 to 31mm, which is divided into two models of 6 to 19mm and 16 to 31mm.

[0034] The utility model can clamp a steel beam 60 with a flange thickness not greater than 31 mm, and the materials of the outer clamp 10 and the inner clamp 20 are easy to obtain and the manufacturing process is simple, thereby reducing production costs and improving production efficiency.

[0035] In addition, refer to Figure 1 and Figure 2 A pressure block 30 is arranged below the clamping groove 21. The pressure block 30 is made of a Q355B plate with a thickness of 8 mm. The pressure block 30 passes through the inner clamp 20 and the outer clamp 10 at the same time. A fixing part 40 which can be movably adjusted and pressurized toward the clamping groove 21 is provided on the pressure block 30, wherein the fixing part 40 is used to bite and fix the clamped object in the clamping groove 21, and the longitudinal direction of the fixing object is set at an acute angle to the opening direction of the clamping groove 21.

[0036] It is understandable that reference 1 and Figure 3The inner clamp 20 and the outer clamp 10 are provided with a clamping groove 21 for placing the clamped object, and a pressing block 30 is provided below the clamping groove 21, which penetrates both the inner clamp 20 and the outer clamp 10, and can effectively limit and fix the inner clamp 20 and the outer clamp 10, thereby preventing the inner clamp 20 and the outer clamp 10 from sliding or loosening when clamping the clamped object. The placement angle of the pressing block 30 is adjusted so that the lateral direction of the pressing block 30 and the opening direction of the clamping groove 21 intersect at an acute angle, presenting a pressing block 30. 0 line, the fixing member 40 passes through the pressure block 30 and is connected by a threaded adjustment and is arranged perpendicular to the pressure block 30, and the clamping end of the fixing member 40 is arranged toward the clamping groove 21, and the longitudinal direction of the fixing member 40 and the opening direction of the clamping groove 21 are also arranged at an acute angle, so that when the fixing member 40 clamps the clamped object in the clamping groove 21, the clamped object is subjected to a force opposite to the opening direction of the clamping groove 21, thereby increasing the bite stability of the utility model on the clamped object, and further improving the earthquake resistance effect of the utility model.

[0037] Among them, reference Figure 3 The outer clamp 10 and the inner clamp 20 are both provided with a through hole 22, and the through hole 22 is adapted to the pressure block 30, thereby ensuring that the lateral direction of the pressure block 30 is set at an acute angle with the opening direction of the clamping groove 21, thereby ensuring that the fixing member 40 of the utility model generates a force opposite to the opening of the clamping groove 21 on the clamped object, thereby increasing the bite stability of the utility model on the clamped object.

[0038] Among them, reference Figure 1 and Figure 2 The fixing member 40 is a pointed torsion shear bolt. When the required torque is reached during installation, the hexagonal head will be twisted off and fall off. In this embodiment, two fixing members 40 are arranged through the pressure block 30. The arrow ends of the fixing members 40 are arranged toward the clamping groove 21. By setting the arrows, the stability of the clamping structure between the fixing members 40 and the clamped object can be increased. The pressure block 30 is provided with an adjustment hole (not marked in the figure), so as to adjust the height of the fixing member 40 on the adjustment hole (not marked in the figure), thereby adjusting the bite force of the fixing member 40 on the clamped object, thereby ensuring the clamping force of the fixing member 40 of the utility model on the clamped object.

[0039] Among them, reference Figure 1 and Figure 3 An anti-slip pattern 211 is provided on the inner wall of the clamping groove 21 away from the fixing member 40 , and the anti-slip pattern 211 is used to increase the friction between the clamped object and the clamping groove 21 .

[0040] Specifically, refer to Figure 3The fixing member 40 squeezes and presses the clamped object in the clamping groove 21, so that the side of the clamped object away from the fixing member 40 abuts against the clamping groove 21. The anti-slip pattern 211 can be used in conjunction with the fixing member 40 to increase the clamping force of the fixing member 40 and the clamping groove 21 on the clamped object, and increase the friction between the clamped object and the clamping groove 21, thereby avoiding the problem of the clamped object loosening or falling off.

[0041] Among them, reference Figure 1 The opening width of the clamping groove 21 is 32 mm, so that the utility model can clamp the steel beam 60 with a flange less than or equal to 31 mm. Combined with the anti-slip pattern 211 and the adjustable setting of the fixing piece 40 on the pressing block 30, the clamping types of the steel beam 60 of the utility model are increased, and the practicality of the utility model is improved to a certain extent.

[0042] Among them, reference Figure 1-Figure 5 The outer clamp 10 includes an outer connecting plate 11 and an outer clamping plate 12, and the outer connecting plate 11 is integrally connected to the outer clamping plate 12. In addition, the inner clamp 20 includes an inner connecting plate 23 and an inner clamping plate 24, and the inner connecting plate 23 is integrally connected to the inner clamping plate 24. In this embodiment, an outer clamping plate 12 is provided on both sides of the outer connecting plate 11, and the outer connecting plate 11 and the outer clamping plate 12 are perpendicular to each other to form a U-shaped structure. Similarly, an inner clamping plate 24 is provided on both sides of the inner connecting plate 23, and the inner clamping plate 24 and the inner connecting plate 23 are perpendicular to each other. Among them, the inner connecting plate 23 is located on the inner side of the outer connecting plate 11 and is connected to the inner side of the outer connecting plate 11. The outer and inner connecting plates 11 and 23 are abutted against each other, and the outer and inner connecting plates 11 and 23 are arranged parallel to each other, and the outer and inner plates 12 and 24 are arranged parallel to each other. Both the outer and inner plates 12 and 24 are provided with through holes 22 for the pressure block 30 to pass through. In addition, both the outer and outer plates 12 and 12 are provided with matching clamping grooves 21 for placing the clamped object. The structural arrangement of the inner clamp 20, the outer clamp 10, the pressure block 30 and the clamping groove 21 ensures that the inner and outer plates 24 and 12 used to clamp the clamped object will not loosen during the clamping process, which improves the structural stability of the utility model for biting and fixing the clamped object to a certain extent.

[0043] Among them, reference Figure 4 and Figure 5 The outer connecting plate 11 and the inner connecting plate 23 are both provided with connecting square holes 111, and the connecting square holes 111 are provided with connecting members 50, and the connecting members 50 are used for connecting structures. In this embodiment, the connecting member 50 is arranged through the connecting square holes 111, and the connecting member 50 is a semicircular head square neck bolt. Through the structural arrangement of the connecting member 50 and the connecting square holes 111, the outer connecting plate 11 and the inner connecting plate 23 can be effectively fixed.

[0044] The utility model also provides a connection structure, referring to 1- Figure 5 The connection structure includes the above-mentioned earthquake-resistant beam clamp, and also includes a steel beam 60, the flange of the steel beam 60 is adapted to the clamping groove 21, and the fixing member 40 abuts and bites with the flange of the steel beam 60, wherein the flange thickness of the steel beam 60 is less than or equal to 31 mm, so that the flange of the steel beam 60 placed in the clamping groove 21 is clamped and bitten by the fixing member 40, and the bite stability between the steel beam 60 and the beam clamp is improved through the structural setting of the pressure block 30, thereby improving the earthquake resistance of the connection structure.

[0045] For further reference, Figure 3-Figure 5 The connection structure also includes a seismic connector 70 and a channel steel 80. One end of the seismic connector 70 is provided with a connection hole 71, and the connection hole 71 is used to connect the beam clamp and the seismic connector 70, wherein the other end of the seismic connector 70 is fixedly connected to one end of the channel steel 80, and the other end of the channel steel 80 is used to connect to the power source.

[0046] Specifically, refer to Figure 4 and Figure 5 The connecting member 50 is arranged by passing through the connecting square holes 111 on the inner connecting plate 23 and the outer connecting plate 11 and the connecting hole 71 on the seismic connecting member 70, wherein the connecting member 50 is a semi-circular head square neck bolt, which is arranged in the connecting square hole 111 through the connecting member 50, so that the connecting member 50 can be conveniently installed at one end of the seismic connecting member 70, reducing the need for multiple tools to fix the two ends of the connecting member 50 before installing the beam clamp and the seismic connecting member 70, thereby improving the installation efficiency, and further reducing the influence of the power source on the steel beam 60 through the beam clamp, thereby increasing the stability of the connection structure between the steel beam 60 and the channel steel 80.

[0047] The product of this technical solution is composed of an outer beam clamp and an inner beam clamp as the main body, which is penetrated by a pressing block, and then a complete set of products is composed of bolts, nuts and other accessories. Among them, the inner beam clamp and the outer beam clamp are both bent from Q235B and above grade plates, and the pressing block is Q355B material; the materials are simple and easy to obtain, and the manufacturing only requires simple stamping and bending, and can be produced continuously and automatically;

[0048] Compared with the general bending beam clamps on the market, this technical solution uses pointed twist-off bolts to bite steel beams. While ensuring sufficient torque, the direction of the pressure block is tilted inward, ensuring that there is an inward buckling force when the pointed bolts bite the steel beams and column flanges, which is more conducive to maintaining the bite stability, thereby better resisting earthquake effects, especially in the direction perpendicular to the steel beam. The mechanical properties of the beam clamp have been greatly improved, thereby ensuring the short board limit of the force value in the project application;

[0049] The back of the beam clamp adopts a square hole design and uses a semi-circular head square neck bolt. When installing the seismic connector, you only need to screw the nut when installing it at high altitude on the project site. In the traditional hexagonal bolt installation, you need to screw the hexagonal head of the hexagonal bolt with one hand and the hexagonal nut with the other hand. At the same time, the square hole and the square neck of the bolt are matched to limit the rotation of the bolt, so it can be operated with one hand, which is convenient for installation and ensures the safety of the installer.

[0050] The inner beam clamp, outer beam clamp and pressure block in the product of this technical solution are all made by cutting and processing the plate materials, with low material cost, and can all be produced by automation with high production efficiency.

Obviously, many modifications and changes can be made according to the content of this specification.
