Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated steel structure buildings, and in particular to a connection system between walls and steel columns. Background Technology

[0002] In prefabricated steel structure buildings, the outer surface of the masonry exterior wall of the embedded exterior wall needs to be flush with the outer surface of the steel column. During construction, tie bars are welded to the side of the steel column, and the wall is stacked on the side of the steel column with tie bars so that the tie bars are embedded in the wall, avoiding large gaps between the steel column and the wall.

[0003] However, since steel columns and walls are made of different materials, vertical through-cracks are prone to appear under the influence of temperature differences, and water leakage is likely to occur at the connection between steel columns and walls. Moreover, when installing existing steel columns, tie bars need to be welded to the side of the steel column on site. Welding will damage the surface coating of the steel column and pose a fire safety hazard. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a connection system between a wall and a steel column, which can solve the problem of rainwater leakage at the contact surface between the steel column and the wall, avoid welding damage to the coating on the surface of the steel column, and improve construction quality.

[0005] A connection system between a wall and a steel column according to an embodiment of the present invention includes: a connecting surface disposed on two horizontally opposite sides of the steel column; a water-stop plate located on the side of the steel column near the connecting surface, the water-stop plate having a water-retaining surface; a water-stop strip disposed between the steel column and the water-stop plate; a receiving groove disposed on the steel column and / or the water-stop plate, the receiving groove being used to receive the water-stop strip, the receiving groove being disposed near the water-retaining surface; and a locking assembly including a connecting body and a bolt group, the connecting body being disposed on the side of the water-stop plate away from the water-retaining surface, the bolt group being used to connect the connecting body and the steel column so that the water-stop strip is tightly attached to the connecting surface.

[0006] A connection system between a wall and a steel column according to an embodiment of the present invention has at least the following beneficial effects:

[0007] 1. This utility model, by setting a water-stop vertical plate, has a water-blocking surface that blocks the direction of water seepage and movement. Furthermore, the horizontal length of the water-blocking surface is relatively large, resulting in a large contact area between the water-blocking surface and the wall. When water enters the gap between the wall and the steel column, the water-blocking surface extends the path of the water through the joint between the wall and the steel column, forcing the water to detour along a longer path during seepage. This greatly reduces the risk of water seepage between the wall and the steel column.

[0008] 2. This utility model uses a water-stop strip located between the water-stop vertical plate and the vertical steel column. When the water-stop strip comes into contact with water, it expands on its own, filling the gap between the wall and the vertical steel column, forcing water to flow around the water-stopping surface, thereby effectively preventing water from penetrating through the gap between the wall and the vertical steel column.

[0009] 3. By setting up a receiving groove, this utility model can accommodate the water-stop strip, thus confining the water-stop strip between the water-stop vertical plate and the vertical steel column. This ensures that the water-stop vertical plate presses the water-stop strip tightly against the vertical steel column, preventing the water-stop strip from failing to waterproof.

[0010] 4. This utility model, by setting up a connecting body and a bolt group, connects the connecting body and the upright steel column, thereby fixing the water-stop plate and the upright steel column. This avoids damage to the surface of the upright steel column caused by welding operations, eliminates fire safety hazards, and allows on-site operations to be transferred to the factory for centralized production. The standardization of joint methods and materials is high, improving construction efficiency.

[0011] According to an embodiment of the present invention, a connection system between a wall and a steel column is provided on the side of the steel column near the water-retaining surface, and a receiving groove is formed between the pressure strip and the water-retaining surface.

[0012] According to an embodiment of the present invention, a connection system between a wall and a steel column is provided, wherein the pressure strip is provided with an arc-shaped portion that matches the water-stopping strip, and the arc-shaped portion is disposed away from the water-blocking surface.

[0013] According to an embodiment of the present invention, a connection system between a wall and a steel column is provided, wherein the water-stop plate, the connecting body, and the pressure strip are welded together as a single unit.

[0014] According to an embodiment of the present invention, a connection system between a wall and a steel column is provided, wherein the connection body has a plurality of connection plates, the plurality of connection plates are arranged in the vertical direction along the water-stop vertical plate, and the bolt group is connected between the connection plates and the steel column.

[0015] According to an embodiment of the present invention, a connection system between a wall and a steel column includes a bolt group comprising a locking bolt and a locking nut. The steel column is provided with a first through hole, and the connecting plate is provided with a second through hole. The locking bolt passes through the first through hole and the second through hole in sequence and is then locked with the locking nut.

[0016] According to an embodiment of the present invention, a connection system between a wall and a steel column is provided, wherein the first through hole is a rectangular hole, and the length of the rectangular hole is arranged along the vertical direction of the steel column.

[0017] According to an embodiment of the present utility model, a connection system between a wall and a steel column further includes tie bars connected to the waterstop plate. Multiple tie bars are provided, and the multiple tie bars are arranged along the vertical direction of the waterstop plate.

[0018] According to an embodiment of the present utility model, a connection system between a wall and a steel column is provided, wherein the water-stop plate is provided with a third through hole, and the tie bar passes through the third through hole and is arranged in a V shape.

[0019] According to an embodiment of the present invention, a connection system between a wall and a steel column is provided, wherein the surface of the steel column is coated with a fireproof and corrosion-resistant coating.

[0031] The following description, in conjunction with the accompanying drawings, describes a connection system between a wall and a steel column according to an embodiment of the present invention.

[0032] In prefabricated steel structure buildings, the outer surface of the masonry exterior wall with embedded exterior walls needs to be flush with the outer surface of the 100mm steel column, referring to... Figure 1 During construction, the steel column 100 is installed and fixed. Then, the foundation beam 260 under the wall is constructed. Tie bars 240 are welded to the side of the steel column 100. The wall 110 is built on the side of the steel column with tie bars 240 so that the tie bars 240 are embedded in the wall 110.

[0033] However, since the steel column 100 and the wall 110 are made of different materials, vertical through-seams are prone to appear under the influence of temperature differences, and water leakage is likely to occur at the connection between the steel column 100 and the wall 110. Moreover, during the installation of the existing steel column, the tie steel bar 240 needs to be welded to the side of the steel column on site. The welding process will damage the surface coating of the steel column 100 and pose a fire safety hazard.

[0034] Based on this, the present invention aims to provide an embodiment of a connection system between a wall and a steel column.

[0035] This utility model provides a connection system between a wall and a steel column, referring to... Figure 2 and Figure 3 It includes a connecting surface 120 and a water-stopping plate 130. The connecting surface 120 is located on the horizontal opposite sides of the vertical steel column 100, and the water-stopping plate 130 is located on the side of the vertical steel column 100 near the connecting surface 120. The water-stopping plate 130 has a water-blocking surface 140.

[0036] Understandably, the water-stop vertical plate 130 has a water-blocking surface 140, which blocks the direction of water penetration and movement. Furthermore, the horizontal length of the water-blocking surface 140 is relatively large, resulting in a large contact area between the water-blocking surface 140 and the wall 110. When water enters the gap between the wall 110 and the vertical steel column 100, the water-blocking surface 140 extends the path of water through the joint between the wall 110 and the vertical steel column 100, forcing water to detour along a longer path during penetration. This significantly reduces the risk of water seepage between the wall 110 and the vertical steel column 100.

[0037] This utility model provides a connection system between a wall and a steel column, referring to... Figure 2 and Figure 3 It also includes a water-stopping strip 150, which is disposed between the steel column 100 and the water-stopping plate 130.

[0038] Understandably, the water-stop strip 150 is located between the water-stop vertical plate 130 and the vertical steel column 100. When the water-stop strip 150 comes into contact with water, it expands on its own, filling the gap between the wall 110 and the vertical steel column 100, forcing water to flow around the water-blocking surface 140, thereby effectively preventing water from penetrating through the gap between the wall 110 and the vertical steel column 100.

[0039] This utility model provides a connection system between a wall and a steel column, referring to... Figure 2 and Figure 3 It also includes a receiving groove 160, which is provided on the upright steel column 100 and / or the water-stop plate 130. The receiving groove 160 is used to receive the water-stop rubber strip 150 and is located near the water-blocking surface 140.

[0040] In the specific design, the water-stop vertical plate 130 can be provided with a receiving groove 160, or the side of the vertical steel column 100 can be provided with a receiving groove 160, or even both the water-stop vertical plate 130 and the vertical steel column 100 can be provided with a receiving groove 160.

[0041] Understandably, the receiving groove 160 can accommodate the water-stop strip 150, so that the water-stop strip 150 is confined between the water-stop vertical plate 130 and the vertical steel column 100, ensuring that the water-stop vertical plate 130 presses the water-stop strip 150 tightly against the vertical steel column 100, thus avoiding the water-stop strip 150 from failing to waterproof.

[0042] This utility model provides a connection system between a wall and a steel column, referring to... Figure 2 and Figure 3 It also includes a locking assembly, which includes a connecting body and a bolt assembly. The connecting body is located on the side of the water-stop vertical plate 130 away from the water-blocking surface 140. The bolt assembly is used to connect the connecting body and the vertical steel column 100 so that the water-stop rubber strip 150 is tightly attached to the connecting surface 120.

[0043] Understandably, the bolt group connects the main body and the steel column 100, thus fixing the water-stop plate 130 and the steel column 100 together. This avoids damage to the surface of the steel column 100 caused by welding operations, eliminates fire safety hazards, and allows on-site operations to be transferred to centralized production in the factory. The materials are highly standardized, which improves construction efficiency.

[0044] In some embodiments of this utility model, reference is made to Figure 4 A pressure strip 170 is provided on the side of the steel column 100 near the water-retaining surface 140, and a receiving groove 160 is formed between the pressure strip 170 and the water-retaining surface 140.

[0045] Understandably, the pressure strip 170 is connected to the water-blocking surface 140, so that the receiving groove 160 is located on the water-blocking surface 140. When water seeps into the space between the wall 110 and the steel column 100, the water-stop strip 150 can immediately block the water seepage and movement, so that the water flows around the water-blocking surface 140, preventing water from passing through the gap between the wall 110 and the steel column 100, and avoiding water accumulation between the water-stop plate 130 and the steel column 100.

[0046] In some embodiments of this utility model, the pressure strip 170 is provided with an arc-shaped portion 180 that matches the water-stopping strip 150, and the arc-shaped portion 180 is disposed away from the water-blocking surface 140.

[0047] Therefore, by providing the arc-shaped portion 180, the arc-shaped portion 180 can confine the water-stop strip 150 within the receiving groove 160, preventing the water-stop strip 150 from falling out of the receiving groove 160.

[0048] In some embodiments of this utility model, reference is made to Figure 4The water-stop vertical plate 130, the connecting body and the pressure strip 170 are welded together as a whole.

[0049] Therefore, after manufacturing the water-stop vertical plate 130, the connecting body and the pressure strip 170 respectively, the water-stop vertical plate 130, the connecting body and the pressure strip 170 are welded together to form a system, which reduces the manufacturing cost of the connection system.

[0050] In some embodiments of this utility model, the connecting body has a plurality of connecting plates 190, which are arranged vertically along the waterstop vertical plate 130, and bolt groups are connected between the connecting plates 190 and the vertical steel column 100.

[0051] Therefore, the connecting body is composed of multiple connecting plates 190, which reduces the amount of material used and helps to reduce manufacturing costs.

[0052] In some embodiments of this utility model, the bolt assembly includes a locking bolt 200 and a locking nut 210. The upright steel column 100 is provided with a first through hole 220, and the connecting plate 190 is provided with a second through hole 230. The locking bolt 200 passes through the first through hole 220 and the second through hole 230 in sequence and is locked with the locking nut 210, thereby facilitating the use of tools to tighten the locking nut 210.

[0053] In some embodiments of this utility model, the first through hole 220 is a rectangular hole, and the length of the rectangular hole is arranged along the vertical direction of the upright steel column 100.

[0054] Understandably, the locking bolt 200 can be adjusted in position within the rectangular hole, allowing the locking bolt 200 to quickly pass through the second through hole 230, making the assembly of the waterstop plate 130 more convenient.

[0055] In some embodiments of this utility model, a tie bar 240 connected to the waterstop plate 130 is also included. Multiple tie bars 240 are provided and arranged in the vertical direction along the waterstop plate 130. Therefore, the tie bars 240 can improve the connection strength between the wall 110 and the steel column 100.

[0056] In some embodiments of this utility model, the water-stop vertical plate 130 is provided with a third through hole 250, and the tie bar 240 is arranged in a V-shape after passing through the third through hole 250, thereby making it more convenient to install the tie bar 240 on the water-stop vertical plate 130.

[0057] In some embodiments of this utility model, the surface of the steel column 100 is coated with a fireproof and anti-corrosion coating, thereby improving the service life of the steel column 100.
