Description

Technical Field

[0001] This invention relates to the field of steel structure beam-column connection technology, specifically to prefabricated steel structure beam-column connection components. Background Technology

[0002] Steel structure beams and columns are beams and columns made of steel materials and are one of the main types of building structures. They are mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Steel structure beams and columns are typically connected at joints using welds, bolts, or rivets, requiring splicing treatment before connection. Steel structure beams and columns are lightweight and easy to construct, making them widely used in large factories, stadiums, and high-rise buildings. In current steel structure building construction, to accelerate the construction process on the construction site and reduce construction waste and time waste, prefabrication and assembly methods are adopted. Large-scale prefabrication and on-site assembly reduce the number of personnel required on the construction site and enable rapid and efficient connection of various building components to form a complete and usable modular building structure, thereby accelerating the construction progress.

[0003] The existing steel structure beams and columns are usually connected by two methods: angle steel bolts for positioning and welding for reinforcement. However, this method is cumbersome to use. When working at heights, the small size of the bolts and nuts makes them easy to slip out of the workers' hands. The falling bolts and nuts pose a safety hazard. The existing steel structure beam and column connection components are not conducive to safe installation work at heights. Summary of the Invention

[0004] The purpose of this invention is to provide prefabricated steel structure beam-column connection components for prefabricated buildings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The prefabricated steel structure beam-column connection components for assembled buildings include two symmetrically arranged sets of steel column clamping frames, and also include:

[0007] A spring-loaded side clamp structure connected to a steel column clamping frame, the spring-loaded side clamp structure including side clamping parts symmetrically installed on the steel column clamping frame, the side clamping parts being used to clamp the steel column, the side clamping parts being connected to a central control part connected to the steel column clamping frame, the central control part being used to adjust the position of the side clamping parts;

[0011] As a further improvement of the present invention: the snap-fit ​​seat is provided with a longitudinal groove, and the snap-fit ​​seat is provided with a plurality of transverse grooves connected to the longitudinal groove. The longitudinal groove and the transverse groove are both movably connected to the steel beam end connection mechanism.

[0012] As a further improvement of the present invention: the steel beam end connection mechanism includes a snap-fit ​​block movably connected to the snap-fit ​​seat, the longitudinal groove and the transverse groove are both movably connected to the snap-fit ​​block, the snap-fit ​​block is movably connected to the pressing mechanism, the snap-fit ​​block is fixedly connected to an end sleeve, the end sleeve is equipped with a bolt, and the bolt is equipped with a nut.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In use, the steel beam end connection mechanism is installed on both ends of the steel beam to be hoisted on the ground. Personnel first clamp the steel column clamping frame into the steel column, ensuring the protruding end of the frame engages. Then, personnel adjust the side clamping parts via the central control unit, causing them to engage with the steel column. This allows the spring-loaded side clamping structure to engage with the steel column, thus restricting the relative position of the steel column clamping frame on the column. The clamping seat is then engaged with the side clamping part. The hoisting equipment at the construction site lifts the steel beam into the air, engaging the steel beam end connection mechanisms at both ends into the clamping seats. Personnel then use a pressing mechanism to limit the position of the steel beam end connection mechanisms installed in the clamping seats, completing the connection of the steel beam and steel column. This invention, through the cooperation between the steel column clamping frame, the spring-loaded side clamping structure, and the steel beam connection mechanism, avoids the need for bolts and nuts during high-altitude operations by using a component splicing method, thus protecting the safety of personnel on the ground.

[0026] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0027] Example 1, see Figures 1 to 8 As shown, the prefabricated steel structure beam-column connection component includes two symmetrically arranged sets of steel column clamping frames 1. Each steel column clamping frame 1 has multiple sets of protruding ends 101. The diameter of each protruding end 101 is slightly smaller than the diameter of the hole opened on the steel column 4, and the protruding end 101 and the hole on the steel column 4 are fitted with a clearance fit, thus facilitating the removal of the steel column clamping frame 1 from the steel column 4. A handle 102 is fixedly installed on each steel column clamping frame 1, facilitating the movement of the steel column clamping frame 1 by personnel. The component also includes:

[0028] The spring-loaded side clamping structure 2 is connected to the steel column clamping frame 1. The spring-loaded side clamping structure 2 includes side clamping parts 201 symmetrically installed on the steel column clamping frame 1. The side clamping parts 201 are used to clamp the steel column 4. The side clamping parts 201 are connected to a central control part 202 connected to the steel column clamping frame 1. The central control part 202 is used to adjust the position of the side clamping parts 201.

[0029] A steel beam connecting mechanism 3 is connected to the side locking part 201. The steel beam connecting mechanism 3 includes a locking seat 301 movably connected to the side locking part 201. The locking seat 301 is movably connected to a pressing mechanism 302 connected to the side locking part 201. A steel beam end connecting mechanism 303 is installed between the pressing mechanism 302 and the locking seat 301. Through the mutual cooperation between the pressing mechanism 302 and the locking seat 301, the pressing mechanism 302 and the locking seat 301 jointly limit the steel beam end connecting mechanism 303. The steel beam end connecting mechanism 303 is used to connect the end of the steel beam 5.

[0030] In use, the steel beam end connection mechanism 303 is installed on both ends of the steel beam 5 to be hoisted on the ground. First, the personnel clamp the steel column clamping frame 1 into the steel column 4, so that the protruding end 101 of the steel column clamping frame 1 is clamped into the steel column 4. Then, the personnel adjust the side clamping part 201 through the central control part 202, so that the side clamping part 201 clamps the steel column 4, thereby making the elastic side clamping structure 2 clamp into the steel column 4, thus restricting the relative position of the steel column clamping frame 1 on the steel column 4. The clamping seat 301 is clamped with the side clamping part 201. The hoisting equipment at the construction site hoists the steel beam 5 into the air and makes the steel beam end connection mechanism 303 at both ends of the steel beam 5 clamp into the clamping seat 301. Then, the personnel use the pressing mechanism 302 to limit the steel beam end connection mechanism 303 installed in the clamping seat 301, thereby completing the connection operation between the steel beam 5 and the steel column 4. This invention utilizes the cooperation between the steel column clamping frame 1, the spring-loaded side clamping structure 2, and the steel beam connecting mechanism 3 to avoid installing bolts and nuts during high-altitude operations by splicing the components together, thus protecting the safety of personnel on the ground.

[0031] In one embodiment, the side locking part 201 includes a guide rail 2011 fixedly connected to the steel column locking frame 1. The guide rail 2011 has a dovetail groove, and a sliding frame 2012 is slidably connected to the dovetail groove. Multiple sets of pin blocks 2013 are fixedly installed on the sliding frame 2012. The sliding frame 2012 has a slot 2014 movably connected to the locking seat 301. The sliding frame 2012 is connected to the central control part 202. Personnel move the sliding frame 2012 via the central control part 202, causing the sliding frame 2012 to drive the pin blocks 2013 into the steel column 4, thereby connecting the side locking part 201 to the steel column 4.

[0032] In one embodiment, the central control unit 202 includes a central rail frame 2021 fixedly connected to the steel column clamping frame 1. A linkage block 2022 is slidably mounted on the central rail frame 2021, and a handle 2027 is fixedly mounted on the linkage block 2022. When the personnel adjust the linkage block 2022, the handle 2027 provides a force application position for the personnel. A limiting post 2023 adapted to the linkage block 2022 is mounted on the central rail frame 2021. The limiting post 2023 is used to restrict the movement of the linkage block 2022. A first hinge frame 2024 is hinged to the linkage block 2022. The first hinge frame 2024 is slidably connected to a second hinge frame 2025 hinged to the sliding frame 2012. A first spring is installed between the first hinge frame 2024 and the second hinge frame 2025. A first threaded part 2026 adapted to the linkage block 2022 is mounted on the central rail frame 2021. The operator moves the linkage block 2022 by turning the handle 2027, which in turn drives the first hinge frame 2024. The first hinge frame 2024 then drives the second hinge frame 2025 to rotate. Under the push of the first spring, the second hinge frame 2025 drives the sliding frame 2012 to move, thereby adjusting the position of the sliding frame 2012. The operator restricts the movement of the linkage block 2022 by rotating the first threaded part 2026 into the linkage block 2022.

[0033] In one embodiment, the locking seat 301 has a longitudinal groove 3011 and multiple transverse grooves 3012 connected to the longitudinal groove 3011. Both the longitudinal groove 3011 and the transverse grooves 3012 are movably connected to the steel beam end connection mechanism 303. Both the longitudinal groove 3011 and the transverse grooves 3012 are used to engage the steel beam end connection mechanism 303.

[0034] In one embodiment, the steel beam end connection mechanism 303 includes a snap-fit ​​block 3031 movably connected to a snap-fit ​​seat 301. Both the longitudinal groove 3011 and the transverse groove 3012 are movably connected to the snap-fit ​​block 3031. The snap-fit ​​block 3031 is movably connected to a pressing mechanism 302. An end sleeve 3032 is fixedly connected to the snap-fit ​​block 3031. A bolt is installed on the end sleeve 3032, and a nut is installed on the bolt. The steel beam 5 is inserted into the end sleeve 3032, and the bolt passes through the connecting nut of the steel beam 5, thereby connecting the steel beam 5 and the end sleeve 3032 together. Then, through the misaligned connection between the snap-fit ​​block 3031 and the transverse groove 3012, i.e., part of the transverse groove 3012 is not snapped with the snap-fit ​​block 3031, the positional deviation of the steel column 4 is compensated, facilitating the misaligned installation of the steel beam 5.

[0035] In one embodiment, the crimping mechanism 302 includes a threaded seat 3021 fixedly connected to the sliding frame 2012. The threaded seat 3021 is threadedly connected to a second threaded member 3022, and the second threaded member 3022 is threadedly connected to a pressure frame 3023. The pressure frame 3023 is movably connected to the threaded seat 3021 and to the snap-fit ​​seat 301. When the pressure frame 3023 is pressed into the threaded seat 3021, the second threaded member 3022 is rotated, causing it to be threadedly connected to the pressure frame 3023. At this time, the pressure frame 3023 presses against the snap-fit ​​seat 301, thereby restricting the position of the snap-fit ​​block 3031 and the snap-fit ​​seat 301.

[0036] Example 2, based on Example 1, see [link / reference] Figure 1 and Figure 2 The locking seat 301 is fixedly connected to a pressure-increasing anti-slip structure 6. The pressure-increasing anti-slip structure 6 includes an oil pipe 601 fixedly connected to the locking seat 301. A friction frame 604 is slidably connected to the oil pipe 601. A top frame 602 is slidably connected to the oil pipe 601 and movably connected to the locking block 3031. A second spring is installed between the top frame 602 and the locking seat 301. As the locking block 3031 presses against the top frame 602, the top frame 602 presses the oil in the oil pipe 601. The oil pushes the friction frame 604, causing the friction frame 604 to press against the outer wall of the steel column 4, thereby increasing the maximum friction between the friction frame 604 and the steel column 4, thus improving the stability of the connection between the present invention and the steel column 4.

[0037] Working process: During use, the steel beam end connecting mechanism 303 is installed on both ends of the steel beam 5 to be hoisted on the ground. Personnel first clamp the steel column clamping frame 1 into the steel column 4, so that the protruding end 101 of the steel column clamping frame 1 is inserted into the steel column 4. Personnel then move the linkage block 2022 by turning the handle 2027, causing the linkage block 2022 to drive the first hinge frame 2024. The first hinge frame 2024 then drives the second hinge frame 2025 to rotate. Under the push of the first spring, the second hinge frame 2025 drives the sliding frame 2012 to move, thereby adjusting the position of the sliding frame 2012. Personnel then restrict the movement of the linkage block 2022 by screwing the first threaded part 2026 into the linkage block 2022. The sliding frame 2012 then drives the pin block 2013 to insert into the steel beam 4, thereby connecting the side clamping part 201 to the steel column 4. This restricts the relative position of the steel column clamping bracket 1 on the steel column 4. The clamping seat 301 is clamped with the side clamping part 201. The hoisting equipment at the construction site hoists the steel beam 5 into the air and makes the steel beam end connecting mechanism 303 at both ends of the steel beam 5 clamp into the clamping seat 301. The pressure frame 3023 is pressed into the threaded seat 3021. The second threaded part 3022 is rotated so that the second threaded part 3022 is threadedly connected to the pressure frame 3023. At this time, the pressure frame 3023 presses on the clamping seat 301, thereby restricting the position of the clamping block 3031 and the clamping seat 301, thus completing the connection operation between the steel beam 5 and the steel column 4. As the clamping block 3031 presses on the top frame 602, the top frame 602 presses the oil in the oil pipe 601. The oil pushes the friction frame 604, causing the friction frame 604 to squeeze the outer wall of the steel column 4, thereby increasing the maximum friction between the friction frame 604 and the steel column 4.
