Description

Technical Field

[0001] The present invention mainly relates to the technical field of building structures, and specifically is a construction reinforcement device for a roof steel structure support node. Background Technique

[0002] A steel structure building is a building with a load-bearing structure composed of building steel. Generally, load-bearing structures are composed of components such as beams, columns, and trusses made of sections and steel plates. It forms an integral building together with enclosure structures such as roofs, floors, and walls.

[0003] Compared with traditional concrete buildings, steel structure buildings replace reinforced concrete with steel plates or sections, with higher strength and better seismic resistance. And because components can be fabricated in factories and installed on-site, the construction period is greatly reduced. Due to the recyclability of steel, construction waste can be greatly reduced, making it more environmentally friendly and thus widely adopted by countries around the world and applied in industrial and civil buildings. In steel structures, steel beams serve as the main load-bearing structures. During use, steel beams are subject to large forces, especially the angular stress at the connection between the support beam and the top beam is relatively concentrated, which easily causes fatigue of the steel beam, reduces the connection strength and compressive resistance, and affects the service life of the steel beam.

[0004] The existing Chinese patent application with the publication number CN215670149U discloses an enhanced node for connecting beams and columns of a prefabricated high-rise steel structure residence, including an upper beam-column, an installation cylinder, and a reserved hole. A lower beam-column is provided at the bottom end of the upper beam-column, transverse steel beams are provided on both sides of the upper beam-column, and a reinforcement structure is fixed inside the transverse steel beams. Installation structures are installed at the top and bottom ends of the transverse steel beams. The installation structure includes a fixing member, a fastening bolt, and an installation hole. The fixing member is provided at the top and bottom ends of the transverse steel beam, and both sides of the transverse bolt extend to the outside of the lower beam-column. In the present invention, through the setting of the installation structure, during installation, the upper beam-column and the lower beam-column are taken in sequence, the upper beam-column and the lower beam-column are sleeved outside the installation cylinder, the fixing members are installed on both sides of the upper beam-column and the lower beam-column through the transverse bolts in sequence, and then the transverse steel beam is inserted into the middle position between adjacent fixing members, and the transverse steel beam and the fixing member are fixed through the fastening bolt, improving the fastening of the installation interface.

[0005] However, the steel beam support node reinforcement device has the following defects during specific use: In the steel beam support and reinforcement device in the prior art, multiple groups of fixing parts are added and corresponding fastening bolts are used for locking and reinforcement. The fixing parts are fixed to the steel beam by a rigid connection method. When the steel beam is under pressure or deformed due to vibration during construction, the fixing parts cannot adjust autonomously according to the stress condition of the steel beam connection point, and cannot effectively release the stress of the steel beam. Although it can support and reinforce the steel beam connection point, however, the acting force generated by the extrusion or vibration of the steel beam will act on the structural beam at the bottom of the building and apply a vibration force to the reinforcement device supporting the structural beam. At this time, this vibration force will directly affect the reinforcement device. When the vibration force is too large, it is easy to cause damage to the reinforcement device and it is not safe enough. Summary of the Invention

[0006] To solve the deficiencies of the prior art, the present invention provides a construction reinforcement device for the support node of a roof steel structure. This device aims to achieve multi-point support through the mutual cooperation of a buffer component and an elastic reinforcement component, improving the stability and seismic performance of the support node of the roof steel structure.

[0007] To achieve the above object, the present invention is realized through the following technical solutions: A construction reinforcement device for the support node of a roof steel structure, comprising a building structural beam, a fixed seat, a buffer component, and an elastic reinforcement component. The building structural beam is composed of a bottom steel beam, columns, and a top support beam. Pillars are fixedly installed at both ends of the bottom steel beam, and inclined top support beams are fixedly installed at the upper ends of the pillars. The upper ends of the two top support beams are fixedly connected. Buffer components are installed at the angles between the pillars and the top support beams through corresponding fixed seats, and the elastic reinforcement component supports and reinforces the connection points between the pillars and the top support beams; among them, the buffer component includes: A two-way spring telescopic component, which is installed at the angle between the pillar and the top support beam, and the two-way spring telescopic component simultaneously supports and reinforces the pillar and the top support beam, and the elastic reinforcement component is movably connected to the two-way spring telescopic component; A first hydraulic damper, first hydraulic dampers are fixedly installed at both ends of the two-way spring telescopic component, and the outer ends of the first hydraulic dampers are respectively hinged with fixed seats. One of the fixed seats is fixedly connected to the inner side of the pillar, and the other fixed seat is fixedly connected to the bottom of the top support beam. Furthermore, the two-way spring telescopic component includes: A support rod, which is located between the two first hydraulic dampers; A sleeve, sleeves are slidably fitted at both ends of the support rod; A shock-absorbing spring is fixedly arranged inside the sleeve. One end of the shock-absorbing spring is fixedly connected to the opposite side of the corresponding sleeve, and the other end of the shock-absorbing spring is fixedly connected to the opposite ends of the support rod respectively; The elastic reinforcement assembly is movably installed between the included angle between the pillar and the top support beam and the support rod.

[0008] Furthermore, the elastic reinforcement assembly includes: A second hydraulic damper, which is movably installed between the included angle between the pillar and the top support beam and the support rod; A sliding sleeve, one end of the second hydraulic damper is fixedly installed with a sliding sleeve, and the sliding sleeve is sleeved on the support rod and is in sliding fit with it; A sector-shaped support plate, a sector-shaped support plate is integrally and fixedly installed at the included angle between the pillar and the top support beam, and two arc-shaped through grooves concentric with it are opened on the front surface of the sector-shaped support plate; A U-shaped connecting seat, the other end of the second hydraulic damper is fixedly installed with a U-shaped connecting seat, and the sector-shaped support plate is located inside the opening of the U-shaped connecting seat and is in sliding fit with it; Guide columns, two guide columns corresponding to the arc-shaped through grooves are fixedly installed inside the U-shaped connecting seat, and the two guide columns respectively penetrate through the corresponding arc-shaped through grooves and are in sliding fit with them.

[0009] Furthermore, through holes are opened at the opposite ends of the sleeve and the support rod. The two ends of the support rod respectively pass through the corresponding through holes and extend into the two sleeves, and limiting plates are respectively fixedly installed at the two ends of the support rod. The limiting plates are respectively in sliding fit with the inner walls of the corresponding sleeves, and the sleeve and the sliding sleeve are connected through a shock-absorbing assembly.

[0010] Furthermore, the shock-absorbing assembly includes a boss. Bosses are respectively fixedly installed at the two ends of the sliding sleeve, compression springs are respectively fixedly installed at the two ends of the boss, one end of the compression spring is respectively fixedly connected to the opposite ends of the corresponding sleeve, and the compression springs are all sleeved outside the support rod.

[0011] Furthermore, the fixed seat includes a bottom plate and side wings. The bottom plate is directly and firmly connected to the corresponding part of the building structural beam by bolts or welding to ensure that the fixed seat will not loosen or fall off due to force.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. The reinforcement device forms a multi-level support and reinforcement system by setting up a fixed seat, a buffer component, and an elastic reinforcement component.

At the same time, the setting of the elastic reinforcement component, such as the second hydraulic damper, the fan-shaped support plate, and the guide column, can further enhance the structural stability and seismic performance, ensuring that the building structure can maintain integrity and safety during construction or use.

[0013] 2. When the device effectively supports the building structure beam, it can also effectively release the stress of the building structure beam. When the building structure is subjected to external forces, the shock-absorbing spring deforms, absorbs energy, and reduces the impact on the structure. This design not only improves the elasticity of the structure but also can extend the service life of the building structure to a certain extent. At the same time, the combined action of the first hydraulic damper and the second hydraulic damper can further absorb and disperse the impact force, reduce structural vibration, and improve the durability of the structure.

[0014] 3. The design of the elastic reinforcement component allows it to automatically adapt to different angles between the pillar and the top support beam, enabling the reinforcement device to be applied to a variety of different building structures. The fan-shaped support plate and the U-shaped connection seat cooperate with the guide column to slide in the arc-shaped through groove, ensuring flexible adjustment during installation and maintaining the structural stability.

It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0018] Embodiment: A construction reinforcement device for a roof steel structure support node As Figure 1 shown in - 6, a construction reinforcement device for a roof steel structure support node, its specific structure includes: A building structure beam 10, a fixing seat 20, a buffer assembly 30, and an elastic reinforcement assembly 40. The building structure beam 10 is composed of a bottom steel beam 101, support columns 102, and a top support beam 103. The two ends of the bottom steel beam 101 are respectively fixedly installed with support columns 102. The upper ends of the support columns 102 are respectively fixedly installed with an inclined top support beam 103. The upper ends of the two top support beams 103 are fixedly connected. The two top support beams 103 form a triangular structure with the horizontal plane. It is characterized in that buffer assemblies 30 are installed at the angles between the support columns 102 and the top support beam 103 through corresponding fixing seats 20, and the elastic reinforcement assembly 40 supports and reinforces the connection points between the support columns 102 and the top support beam 103. Among them, the buffer assembly 30 includes: A bi-directional spring telescopic assembly 50. The bi-directional spring telescopic assembly 50 is installed at the angle between the support column 102 and the top support beam 103, and the bi-directional spring telescopic assembly 50 simultaneously supports and reinforces the support column 102 and the top support beam 103. The elastic reinforcement assembly 40 is movably connected to the bi-directional spring telescopic assembly 50; The first hydraulic damper 60, both ends of the bidirectional spring telescopic assembly 50 are fixedly installed with the first hydraulic damper 60, and fixed seats 20 are respectively hinged and installed at the outer ends of the first hydraulic damper 60. One of the fixed seats 20 is fixedly connected to the inner side of the support column 102, and the other fixed seat 20 is fixedly connected to the bottom of the top support beam 103. The above working principle: When the device reinforces the building structural beam 10, a triangular support structure is formed among the support column 102, the top support beam 103 and the bidirectional spring telescopic assembly 50. According to the stability principle of the triangle, the external forces received by the support column 102 and the top support beam 103 can be evenly dispersed to each component of the buffer assembly 30, thus avoiding structural damage caused by excessive single-point force. When the bidirectional spring telescopic assembly 50 is squeezed, the pressure received by the bidirectional spring telescopic assembly 50 can be transmitted to the first hydraulic damper 60 connected thereto. The first hydraulic damper 60 cancels the pressure or vibration force received by the arrowhead structural beam 10. The elastic reinforcement assembly 40 can further divide the triangle formed among the support column 102, the top support beam 103 and the bidirectional spring telescopic assembly 50 into several triangular support structures, and the elastic reinforcement assembly 40 can elastically support the connection points of the support column 102 and the top support beam 103, further improving the stability and safety of the overall structure of the building structural beam 10.

[0019] According to Figure 5 As shown, the bidirectional spring telescopic assembly 50 includes: a support rod 501, the support rod 501 is located between the two first hydraulic dampers 60; a sleeve 70, both ends of the support rod 501 are slidably fitted with the sleeve 70, both ends of the support rod 501 are inserted into the corresponding sleeve 70 and slidably cooperate with it; a shock-absorbing spring 502, the shock-absorbing spring 502 is fixedly arranged in the sleeve 70, one end of the shock-absorbing spring 502 is fixedly connected to the opposite side of the corresponding sleeve 502, and the other end of the shock-absorbing spring 502 is respectively fixedly connected to the opposite end of the support rod 501; the elastic reinforcement assembly 40 is movably installed between the included angle of the support column 102 and the top support beam 103 and the support rod 501.

[0020] When the bidirectional spring telescopic assembly 50 supports and reinforces the building structure beam 10, the overall length of the vertical spring telescopic assembly 50 can be adjusted through the mutual cooperation between the support rod 501 and the sleeve 70. And through the corresponding shock-absorbing spring 50, the bidirectional spring telescopic assembly 50 can provide additional elastic support for the first hydraulic damper 60. When the building structure beam 10 is subjected to an external force, the first hydraulic damper 60 squeezes the sleeve 70. At this time, the shock-absorbing spring 502 deforms and absorbs energy, reducing the impact on the structure. It can play a good shock-absorbing and buffering effect when the support rod 501 is affected by the vibration force, reducing the influence of the vibration force on the bidirectional spring telescopic assembly 50, enhancing the elasticity and seismic resistance of the structure, and improving safety; when an external force acts on the building structure beam 10, the bidirectional spring telescopic assembly 50 and the first hydraulic damper 60 act together to absorb and disperse the impact force, reduce the structural vibration, improve the seismic performance and durability of the structure, and extend the service life.

[0021] As shown in Figure 6 The elastic reinforcement assembly 40 includes: a second hydraulic damper 401, which is movably installed between the included angle between the column 102 and the top support beam 103 and the support rod 501; a sliding sleeve 402, one end of the second hydraulic damper 401 is fixedly installed with a sliding sleeve 402, and the sliding sleeve 402 is sleeved on the support rod 501 and is slidably matched with it; a sector-shaped support plate 403, a sector-shaped support plate 403 is integrally and fixedly installed at the included angle between the column 102 and the top support beam 103, and two arc-shaped through grooves 404 concentric with it are opened on the front surface of the sector-shaped support plate 403; a U-shaped connecting seat 405, the other end of the second hydraulic damper 401 is fixedly installed with a U-shaped connecting seat 405, and the sector-shaped support plate 403 is located inside the opening of the U-shaped connecting seat 405 and is slidably matched with it; a guide post 406, two guide posts 406 corresponding to the arc-shaped through grooves 404 are fixedly installed in the U-shaped connecting seat 405, and the two guide posts 406 respectively penetrate the corresponding arc-shaped through grooves 404 and are slidably matched with them, and the two guide posts 406 can move along the trajectories of the corresponding arc-shaped through grooves 404 simultaneously.

[0022] When an external force acts, the second hydraulic damper 401 can absorb and disperse the impact force received by the support rod 501. The sliding sleeve 402 can slide on the support rod 501. At the same time, the sector-shaped support plate 403 and the U-shaped connecting seat 405 can slide in the arc-shaped through groove 404 through the guide post 406, and can automatically adapt to the included angle between the support column 102 and the top support beam 103 during installation. Moreover, stable triangular support structures can be formed between the support column 102, the second hydraulic damper 401 and the support rod 501, and between the top support beam 103, the second hydraulic damper 401 and the support rod 501, further improving the structural stability and seismic performance and enhancing the overall safety.

[0023] A through hole 503 is provided at one end of the sleeve 70 opposite to the support rod 501. Both ends of the support rod 501 pass through the corresponding through holes 503 and extend into the two sleeves 70 respectively. And limit plates 504 are fixedly installed at both ends of the support rod 501 respectively. The limit plates 504 are respectively in sliding fit with the inner walls of the corresponding sleeves 70, and the sleeve 70 and the sliding sleeve 402 are connected by a shock-absorbing assembly 80. The limit plate 504 can prevent the support rod 501 from slipping out of the sleeve 70, can form corresponding limits between the support rod 501 and the sleeve 70, and improves the reliability of the device.

[0024] The shock-absorbing assembly 80 includes a boss 801. Bosses 801 are fixedly installed at both ends of the sliding sleeve 402 respectively. Compression springs 802 are fixedly installed at both ends of the boss 801 respectively. One end of each compression spring 802 is fixedly connected to the opposite end of the corresponding sleeve 70 respectively, and the compression springs 802 are all sleeved outside the support rod 501. The shock-absorbing assembly 80 connects the sleeve 70 and the sliding sleeve 402 through the boss 801 and the compression spring 802, further absorbs and disperses the impact force, improves the overall elasticity and seismic performance of the structure, and ensures the stability and safety of the structure when stressed.

[0025] The fixed seat 20 includes a bottom plate 201 and side wings 202. The bottom plate 201 is directly and firmly connected to the corresponding part of the building structure beam 10 (such as the inner side of the support column 102 or the bottom of the top support beam 103) by bolts or welding, ensuring that the fixed seat 20 will not loosen or fall off due to stress.
