Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant fire protection, in particular to an earthquake-resistant support for building fire protection. Background Art

[0002] Building fire protection refers to the fire prevention, fire extinguishing, evacuation and emergency rescue measures taken during the design, construction, use and management of a building. It aims to minimize the possibility of fire and quickly control the fire when it occurs to ensure the safety of personnel, property and the integrity of the building structure. If the fire-fighting facilities are damaged during an earthquake, they will not be able to work normally when a fire occurs and will lose their proper fire-fighting, evacuation and other functions. Therefore, fire-fighting earthquake-resistant supports are needed.

[0003] In existing building fire protection systems, fire protection pipe supports typically utilize traditional rigid connections, bolting or welding the supports directly to walls or other building structures. This simple structure is relatively easy to install, relying on a direct, rigid connection between the pipe and the support to support the weight and ensure stability. The support structure typically connects to the pipe using a crossbar, and installation often requires the coordinated efforts of multiple operators to ensure accurate positioning of the support and pipe.

[0004] However, there are some problems in the installation process of the fire protection pipe bracket in the existing technology. Since the bracket and the pipe need to be fixed at the same time during the installation process, multiple operators are usually required to hold different parts of the bracket respectively and then perform the installation. The operation is relatively cumbersome, especially in some scenarios with narrow space or high operation difficulty, which easily increases the difficulty of installation. In addition, the traditional hard-connected bracket lacks an effective buffering and adjustment mechanism when encountering external force impact or pipe vibration, which easily causes the pipe to be damaged or loosened due to uneven force, increasing the difficulty of maintenance and repair. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a building fire-fighting earthquake-resistant bracket, which aims to improve and solve the problem that one operator needs to hold one side of the bracket and another operator needs to install the other side of the bracket on the cross bar, which is a cumbersome operation.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a building fire-fighting and earthquake-resistant bracket, comprising a cross bar, a tooth block 1 arranged in a straight line fixedly connected to the inside of the cross bar, a slider slidably connected to the inside of the cross bar, a limit assembly is provided inside the cross bar, and the limit assembly is used to drive the slider to reset, a limit groove is provided inside the slider, a limit plate 1 is slidably connected to the inside of the slider, a tooth block 2 is fixedly connected to the bottom of the limit plate 1, the tooth block 2 is engaged with the tooth block 1, a telescopic rod is provided inside the slider, a first spring is sleeved on the outer wall of the telescopic rod, one end of the telescopic rod and the first spring are fixedly connected to the inside of the slider, and the other end of the telescopic rod and the first spring are fixedly connected to the top of the limit plate 1, a bracket is provided on the top of the slider, a bolt is threadedly connected to the inside of the slider, and the bracket is connected to the slider through the bolt.

[0008] The limiting assembly includes a limiting block, which is fixedly connected to the inside of the cross bar, and the sliding block is slidably connected to the outer wall of the limiting block through a limiting groove.

[0009] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:

[0014] One end of the connecting column is fixedly connected to a connecting plate, and the top of the connecting plate is fixedly connected to a connecting block 1.

[0015] As a further description of the above technical solution:

[0016] A second spring is sleeved on the outer wall of the connecting column, and the connecting column is slidably connected to the inside of the supporting rod.

[0017] As a further description of the above technical solution:

[0018] A second spring is sleeved on the outer wall of the connecting column, one end of the second spring is fixedly connected to the inside of the supporting rod, and the other end of the second spring is fixedly connected to the top of the second limiting plate.

[0019] As a further description of the above technical solution:

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, first, the slider is limited by sliding on the outer wall of the limit block through the limit groove, and the tooth block 2 is limited in the slider through the limit plate 1, thereby achieving the effect of pre-positioning the pipe bracket. This solves the problem that when installing the fire pipe on the building fire-fighting and earthquake-resistant bracket, one operator needs to hold one side of the bracket, and then another operator needs to install the other side of the bracket on the cross bar, which is a relatively cumbersome operation. This improves the convenience of the building fire-fighting and earthquake-resistant bracket.

[0023] 2. In the utility model, the connecting column is pulled out from the supporting rod, and the tension of the second spring pushes the limiting plate 2 and then drives the connecting column to reset. At the same time, the output end of the spring damper absorbs the vibration through the squeeze between the limiting plate 2 and the supporting rod, thereby achieving the effect of buffering the pipeline. It solves the problem that the traditional bracket is only directly connected to the wall, resulting in the inability to release stress when the pipeline vibrates, and improves the practicality of the building fire-fighting and earthquake-resistant bracket.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3 When the cam 1 is in the state of being moved, the cam 11 is moved along the track 12 and the track 13 is moved along the track 14 so that the track 13 can be moved in a predetermined manner. The first spring 11 is used to provide tension so that the slider 4 and the limit plate 8 can be reset to the initial position, ensuring that they do not loosen or move during use. The telescopic rod 10 and the first spring 11 are fixedly connected to the inside of the slider 4 at one end and the other end are fixedly connected to the top of the limit plate 8, thereby providing a stable supporting force for the limit plate 8. A bracket 6 is provided on the top of the slider 4, and the bracket 6 is connected to the slider 4 by a bolt 7. The bolt 7 is connected to the inside of the slider 4 by a threaded connection, ensuring that the bracket 6 and the slider 4 are tightly combined to prevent loosening during use. The limit assembly includes a limit block 2, which is fixedly connected to the inside of the cross bar 1. The limit block 2 is used to provide a sliding guide for the slider 4. The slider 4 is slidably connected to the outer wall of the limit block 2 through the limit groove 5, thereby ensuring the direction and position accuracy of the slider 4 when sliding inside the cross bar 1, achieving the effect of installation and adjustment;

[0032] Specifically, when the cross bar 1 is connected to the fire pipe, it is first necessary to adjust the position of the slider 4 inside the cross bar 1. The slider 4 slides and limits along the outer wall of the limit block 2 through the limit groove 5 to ensure that the movement path of the slider 4 is controlled and will not deviate. At the same time, the tooth block 2 9 inside the slider 4 is engaged with the tooth block 1 3, so as to achieve accurate pre-positioning of the slider 4. The tooth block 2 9 is limited inside the slider 4 by the limit plate 1 8, and under the tension support of the first spring 11, it is ensured that the tooth block 2 9 is firmly embedded in the tooth block 1 3, providing a stable support structure. Then, the fire pipe is firmly placed on the cross bar 1, and the bracket 6 is fastened and fixed above the pipe. Finally, the slider 4 is reliably connected to the cross bar 1 by the bolt 7. The whole process ensures that the bracket 6 can be effectively pre-positioned during the installation process, thereby achieving a safe and stable pipe support effect.

[0033] Reference Figure 4, both ends of the crossbar 1 are fixedly connected with a connecting block 2 19, which is used to firmly connect the crossbar 1 to other components to ensure that both ends of the crossbar 1 are firm and stable. One side of the connecting block 2 19 is fixedly connected with a support rod 12, which is used to support the entire structure and provide support and sliding space for internal components. The internal sliding connection of the support rod 12 is connected to a limit plate 2 13, which can slide inside the support rod 12 to play a limiting and buffering role to ensure the stability of the connection structure. One side of the limit plate 2 13 is fixedly connected with a connecting column 15, and the connecting column 1 By connecting with the second limiting plate 13, the flexible sliding of the support assembly is achieved, and the stability of the entire structure is provided. One end of the connecting column 15 is fixedly connected to a connecting plate 17. The function of the connecting plate 17 is to provide a connection interface for other structures to ensure the mutual cooperation and stable connection between the components. The top of the connecting plate 17 is fixedly connected to a connecting block 18. The connecting block 18 further ensures the firmness and overall stability of the connection structure. The outer wall of the connecting column 15 is provided with a second spring 16. The second spring 16 is used to provide elastic support. When the connecting column 15 is on the support rod 12 When sliding inside, the tension of the second spring 16 can ensure that the connecting column 15 automatically resets, and the connecting column 15 is slidably connected to the inside of the support rod 12, ensuring that it can slide smoothly in the support rod 12 when subjected to external force, thereby achieving elastic adjustment and limiting effects. The outer wall of the connecting column 15 is sleeved with a second spring 16, and one end of the second spring 16 is fixedly connected to the inside of the support rod 12 to ensure that one end of the spring is always fixed, and the other end is fixedly connected to the top of the limit plate 2 13, so that the elasticity of the spring can provide stable support for the limit plate 2 13, and the support rod 12 is provided inside. There is a spring damper 14, which is used to provide additional buffering when the connecting column 15 slides, thereby effectively absorbing vibration and reducing the impact of external forces on the connection structure. The top of the spring damper 14 is fixedly connected to the bottom of the second limit plate 13 to ensure that the spring damper 14 can effectively transmit the vibration force and absorb excess energy through the damping effect. The support rod 12 is connected to the output end of the spring damper 14 to ensure that the entire system can remain stable when the pipeline vibrates. The buffering effect of the spring damper 14 effectively protects the pipeline system and extends its service life.

[0034] Specifically, when the cross bar 1 is connected to the wall, the cross bar 1 is first firmly connected to the wall through the support rod 12 to ensure the stability of the entire structure. At this time, the pipeline pulls the support rod 12 through the action of the cross bar 1, and the connecting plate 17 is tightly connected to the limit plate 2 13 through the connecting column 15. The limit plate 2 13 and the support bar 12 are connected by a spring damper 14, thereby increasing the seismic stability of the system. In addition, a second spring 16 is provided on the outer wall of the connecting column 15, and its tension continuously acts on the limit plate 2 13. When subjected to external force, it pushes the connecting column 15 to retract into the support Inside the rod 12, the connection is tightened and protected. When the pipeline vibrates during use, the connecting column 15 will be pulled out from the inside of the support rod 12 under the action of the vibration, and then the tension of the second spring 16 immediately pushes the limit plate 2 13, so that the connecting column 15 is quickly reset. At the same time, during the reset process of the connecting column 15, the spring damper 14 effectively absorbs the vibration energy through the mutual compression between the limit plate 2 13 and the support rod 12, reduces the impact of the pipeline vibration on the overall structure, thereby achieving the effect of effectively buffering the pipeline vibration and improving the stability and durability of the system.

[0035] Working principle: When using the fire-fighting and earthquake-resistant bracket of the building, first connect the crossbar 1 with the fire-fighting pipe, adjust the position of the slider 4 in the crossbar 1, and the slider 4 slides and limits on the outer wall of the limit block 2 through the limit groove 5, and the tooth block 2 9 in the slider 4 is embedded between the tooth block 1 3 to pre-position it. The tooth block 2 9 is limited in the slider 4 by the limit plate 1 8 and supported by the tension of the first spring 11, so that the tooth block 2 9 can be embedded in the tooth block 3 stably. Then place the pipe on the crossbar 1, buckle the bracket 6 with the pipe, and connect the slider 4 with the bolt 7 to achieve the effect of pre-positioning the bracket 6. Then, when connecting the crossbar 1 to the wall, the crossbar 1 is connected through the support rod 12 is connected to the wall, the pipe pulls the support rod 12 through the cross bar 1, the connecting plate 17 is connected to the limit plate 2 13 through the connecting column 15, the limit plate 2 13 and the support rod 12 are connected through the spring damper 14, and the tension of the second spring 16 sleeved on the outer wall of the connecting column 15 pushes the limit plate 2 13 to retract the connecting column 15 into the support rod 12. When the pipe vibrates, the connecting column 15 is pulled out from the support rod 12, and the tension of the second spring 16 pushes the limit plate 2 13 to drive the connecting column 15 to reset. At the same time, the output end of the spring damper 14 absorbs the vibration by squeezing between the limit plate 2 13 and the support rod 12, thereby achieving the effect of buffering the pipe.
