Description

Technical Field

[0001] This utility model relates to the technical field of steel beam and concrete shear wall connection joint structure, specifically a steel beam and concrete shear wall connection node structure. Background Technology

[0002] According to the patent application CN205742539U, "This utility model relates to a connection node, particularly a connection node between a steel beam with anchor bar units and a multi-cavity steel plate shear wall, belonging to the field of steel structures. It includes a steel plate shear wall and a steel beam, with the steel beam located on the outer wall of the end unit of the steel plate shear wall. An anchor bar unit is provided in the end unit of the steel plate shear wall, and concrete is provided within the steel plate shear wall. The connection node between the steel beam with anchor bar units and the multi-cavity steel plate shear wall has a reasonable structure, is easy to process, and improves overall integrity and ductility."

[0003] Regarding the aforementioned related technologies, the inventors believe that there are inconveniences in fixed installation and the lack of pre-reserved expansion joints. Furthermore, the concrete structure may undergo natural deformation under conditions such as temperature and humidity changes, seismic forces, and uneven foundation settlement, potentially leading to damage to the shear wall. Therefore, there is an urgent need to improve the connection node structure between the steel beam and the concrete shear wall to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a connection node structure between a steel beam and a concrete shear wall to solve the problems of inconvenient installation and lack of expansion joints mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection node structure between a steel beam and a concrete shear wall, comprising a shear wall, a grouting groove provided in the middle of the shear wall for subsequent concrete pouring, a steel beam provided on the side of the shear wall, a support plate fixedly provided below the steel beam, the support plate being supported by a support member, and the connection node structure between the steel beam and the concrete shear wall including a positioning mechanism and an expansion joint extension mechanism.

[0006] Preferably, the shear wall is formed by binding steel bars to form a frame, and steel templates are installed on both sides of the frame. The grouting groove is designed with a convex opening.

[0007] Preferably, the pallet and support are made of high-strength steel, the steel beam is hollow to facilitate the installation of bolts and nuts, and the steel beam is made of lightweight steel.

[0008] Preferably, the positioning mechanism includes a locking block, which is fixedly installed on the right side of the shear wall. The locking block is designed in the shape of a snap-fit. The left side of the steel beam is designed with a locking groove, which is used in conjunction with the locking block. The locking block is provided with a through hole.

[0009] Preferably, a limiting groove is provided on the right side of the shear wall, the limiting groove is located below the locking block, a baffle is provided in the limiting groove, and a through hole is provided on the baffle.

[0010] Preferably, a spring is provided below the baffle. Two sets of springs are provided. The two ends of the springs are fixedly installed between the baffle and the shear wall. Before the steel beam is installed, the springs are in a natural state. At this time, the through holes on the locking block do not match the through holes provided on the baffle.

[0011] Preferably, the expansion joint extension mechanism includes a partition plate, with screws at both the upper and lower ends of the partition plate. A bolt is movably installed between the partition plate and the inner wall of the grouting groove. A second spring is movably installed on the bolt, and the second spring is fixed between the shear wall bolts. A nut groove is provided on the inner wall of the grouting groove, with the nut groove positioned directly opposite the end of the bolt, allowing the end of the bolt to fully engage with the nut groove. Before the steel beam is installed, it is in a stretched state with the end of the bolt abutting against the baffle. When the steel beam is installed on the shear wall, the through hole on the locking block is aligned with the through hole on the baffle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The connection node structure between the steel beam and the concrete shear wall features a locking block design at the installation position of the shear wall and the steel beam. This design helps to prevent the steel beam from shaking during installation. At the same time, the support plate provides auxiliary support for the steel beam. The baffle design allows the bolts to be directly locked in the nut groove after the steel beam is installed, preventing the bolts from rotating and facilitating subsequent fixing.

[0014] 2. The connection node structure between the steel beam and the concrete shear wall uses a partition design to leave a certain expansion joint between the concrete and the shear wall. This prevents the subsequent concrete structure from deforming naturally under conditions such as temperature changes, humidity changes, seismic action, and uneven foundation settlement, which could damage the overall structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figures 1-4 This utility model provides a technical solution: a connection node structure between a steel beam and a concrete shear wall, including a shear wall 1, a grouting groove 5 in the middle of the shear wall 1 for later concrete pouring, a steel beam 2 on the side of the shear wall 1, a support plate 3 fixedly installed below the steel beam 2, and the support plate 3 and the shear wall 1 supported by a support member 4. The connection node structure between the steel beam and the concrete shear wall includes a positioning mechanism and an expansion joint extension mechanism.

[0023] Shear wall 1 is formed by binding steel bars to form a frame, and steel formwork is installed on both sides of the frame. The grouting groove 5 is designed with a convex groove.

[0024] The pallet 3 and the support 4 are both made of high-strength steel. The steel beam 2 is hollow inside, which facilitates the installation of bolts and nuts. The steel beam 2 is made of lightweight steel.

[0025] The positioning mechanism includes a locking block 201, which is fixedly installed on the right side of the shear wall 1. The locking block 201 is designed in the shape of a snap-fit. The left side of the steel beam 2 is designed with a slot 202, which works in conjunction with the locking block 201. The locking block 201 is provided with a through hole 209.

[0026] A limiting groove 207 is provided on the right side of the shear wall 1. The limiting groove 207 is located below the locking block 201. A baffle 206 is provided inside the limiting groove 207, and a through hole is provided on the baffle 206.

[0027] A spring 208 is installed below the baffle 206. There are two sets of springs 208. The two ends of the springs 208 are fixedly installed between the baffle 206 and the shear wall 1. Before the steel beam 2 is installed, the springs 208 are in their natural state. At this time, the through hole 209 on the locking block 201 does not match the through hole on the baffle 206.

[0028] When installing shear wall 1 and steel beam 2, auxiliary positioning is required first to facilitate the subsequent installation of bolts 205. This allows the slot 202 on steel beam 2 to engage with the fixed block 201 on shear wall 1. Steel beam 2 is then installed along the block 201 on shear wall 1. When steel beam 2 rests on support plate 3, baffle 206 located below block 201 moves downward under the action of steel beam 2, causing the through hole on block 201 to engage with the through hole on baffle 206. At this time, bolt 205, which is pressed against baffle 206, is ejected outward by spring 303 and engages with mounting hole 203. Meanwhile, nut groove 304 designed on the inner wall of grouting groove 5 prevents bolt 205 from rotating, facilitating the subsequent installation of nuts. Example

[0029] Please see Figure 5 This utility model provides a technical solution: a connection node structure between a steel beam and a concrete shear wall, wherein the expansion joint extension mechanism includes a partition plate 301, and screws 302 are provided at the upper and lower ends of the partition plate 301. Bolts 205 are movably installed between the partition plate 301 and the inner wall of the grouting groove 5. A second spring 303 is movably installed on the bolt 205. The second spring 303 fixes the bolts 205 between the shear wall 1. A nut groove 304 is provided on the inner wall of the grouting groove 5. The nut groove 304 is positioned directly opposite the end of the bolt 205, and the end of the bolt 205 can be fully engaged with the nut groove 304. Before the steel beam 2 is installed, it is in a stretched state and the end of the bolt 205 abuts against the baffle 206. When the steel beam 2 is installed on the shear wall 1, the through hole 209 on the locking block 201 is aligned with the through hole on the baffle 206.

[0030] After the steel beam 2 is installed, concrete is poured into the grouting groove 5. The distance between the partition plate 301 and the shear wall 1 is 5mm. After the concrete in the grouting groove 5 has solidified, the nut on the screw rod 302 is tightened to separate the partition plate 301 from the concrete, leaving a 5mm expansion joint between the concrete and the partition plate 301.
