Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a joint covering structure for interior walls and steel columns. Background Technology

[0002] Steel structures, a major structural type in the construction field, are primarily composed of steel materials. These structures typically consist of steel beams, columns, trusses, and other components made of materials such as shaped steel and steel plates, which are connected by welds, bolts, or rivets. Due to their lightweight and ease of construction, steel structures are widely used in large factories, stadiums, and high-rise buildings.

[0003] Steel structure columns and building interior walls are generally connected by rigid connections, including welding, bolting, and grooved connections. Traditional rigid connections, such as welding or bolting, usually transfer loads rigidly and have high structural stiffness, but may lead to stress concentration, especially at the junction of brick walls and steel columns, where cracking is prone to occur.

[0004] A search revealed that utility model publication CN205502236U proposed a connection node between an interior wall and a steel column. However, this node only uses self-tapping screws and sealant for connection, and the problem of easy cracking at the junction of the brick wall and the steel column still exists. Summary of the Invention

[0005] To address the problem of stress concentration caused by rigid connections between existing steel structure columns and building interiors, leading to cracking at the junction of brick walls and steel columns, this invention proposes a joint covering structure between the interior wall and the steel column to solve the aforementioned problem.

[0006] A joint covering structure for an interior wall and a steel column includes a steel column and an interior wall. The interior wall is a precast component. A positioning column is installed on the surface of the steel column. At least one buffer is installed on the surface of the interior wall. The positioning column and the buffer cooperate to connect the steel column and the interior wall. The surfaces of the steel column and the interior wall are covered with a mortar layer.

[0007] Furthermore, the positioning columns and buffer components work together to replace the traditional rigid connection, allowing for slight displacement between the steel columns and the inner walls, avoiding stress concentration, absorbing load and deformation energy through flexible connections, reducing the risk of cracking at the junction, and further improving the seismic performance of the structure.

[0008] Furthermore, the buffer includes a mounting base, which is fixedly connected to the inner wall. The mounting base includes a first plate-shaped portion and a second plate-shaped portion, and a fixing groove is formed on the surface of the first plate-shaped portion.

[0009] Furthermore, a corrugated stainless steel mesh belt mounting groove is provided on the lateral surface of the second plate-shaped portion, and a connecting groove is provided at the bottom of the stainless steel mesh belt mounting groove, the connecting groove penetrating the bottom of the stainless steel mesh belt mounting groove. A first positioning groove is provided on the surface of the second plate-shaped portion, the first positioning groove penetrating the second plate-shaped portion and communicating with the corrugated stainless steel mesh belt mounting groove.

[0010] Furthermore, the connecting grooves help the mortar or foaming agent penetrate better, further enhancing the adhesion of the mortar or foaming agent.

[0011] Furthermore, it also includes an installation block and a corrugated stainless steel mesh belt. The surface of the installation block is provided with a second positioning groove, which penetrates the installation block. The installation block extends into the installation groove of the stainless steel mesh belt until the first positioning groove and the second positioning groove are aligned. The installation block moves linearly along the installation groove of the stainless steel mesh belt.

[0012] Furthermore, the mounting base is divided into a first plate-shaped part and a second plate-shaped part, which are respectively equipped with a fixing groove and a corrugated stainless steel mesh belt installation groove to facilitate subsequent modular installation. At the same time, the fixing groove ensures a stable connection between the buffer and the inner wall, and the corrugated stainless steel mesh belt installation groove provides a precise installation path for the mesh belt, further improving construction efficiency.

[0013] Furthermore, at least one corrugated stainless steel mesh belt is connected to the lateral surface of the mounting block, and a mounting block is connected to both ends of the corrugated stainless steel mesh belt. The surface of the corrugated stainless steel mesh belt is uniformly provided with through holes.

[0014] Furthermore, the mounting block aligns with the first positioning groove via the second positioning groove, enabling adjustable linear movement; the corrugated stainless steel mesh belt is elastic, and the surface through holes enhance the adhesion of mortar or foaming agent, connecting the steel column and the inner wall into a whole.

[0015] Furthermore, during installation, the positioning column is inserted into the first and second positioning grooves by moving the inner wall to position the corrugated stainless steel mesh belt. Then, foaming agent or mortar is filled into the connection between the inner wall and the steel column, and sealant is used on the outside to seal the connection, forming the inner wall and the steel column into a whole.

[0016] Furthermore, the elasticity of the corrugated stainless steel mesh belt can adapt to structural deformation, and the through holes improve the adhesion between the mortar layer and the steel column, reducing the risk of hollowing and falling off.

[0017] Furthermore, a mortar leveling layer is provided on the surface of the steel column, which extends into the inner wall surface until it completely covers the surface of the steel column.

[0018] Furthermore, a fire-retardant coating is applied between the mortar leveling layer and the steel column surface. The fire-retardant coating is applied to the steel column surface, and the outer layer is covered by the mortar leveling layer, forming double protection.

[0019] Furthermore, the fire-retardant coating delays the softening of steel columns at high temperatures, and the mortar layer isolates oxygen and fire sources, significantly improving the fire resistance limit.

[0020] Furthermore, the mortar leveling layer is covered with galvanized steel wire mesh.

[0021] Furthermore, the galvanized steel wire mesh surface is covered with fiberglass mesh, which extends into the inner wall surface until it completely covers the inner wall and steel column surfaces, and is then compacted with mortar. The galvanized steel wire mesh embedded in the mortar layer enhances crack resistance, while the fiberglass mesh covering the surface disperses stress.

[0022] Furthermore, galvanized steel wire mesh inhibits mortar shrinkage cracks, and fiberglass mesh prevents surface cracking, extending the service life of the cladding structure.

[0023] Compared to existing technologies, the structure in this application utilizes positioning columns on the surface of the steel columns to form a flexible connection with the buffer components of the inner walls, allowing for minor displacement to absorb dynamic loads. The mounting bases of the buffer components achieve modular installation through fixing grooves and corrugated stainless steel mesh installation grooves. The corrugated stainless steel mesh, with its adjustable design of the mounting blocks, elastically adapts to structural deformation, and its surface perforations enhance mortar adhesion, reducing the risk of hollow areas. The multi-layer protection system includes fire-retardant coatings to delay the high-temperature softening of the steel columns, a mortar leveling layer to isolate fire sources, galvanized steel wire mesh to inhibit shrinkage cracks, and fiberglass mesh to disperse surface stress.

[0024] Compared to traditional welding or bolted connections, this structure significantly reduces the risk of cracking through flexible buffering and layered protection, improving seismic and fire resistance. At the same time, the modular design simplifies the construction process, balancing efficiency and economy, and is suitable for high-safety scenarios such as high-rise buildings and earthquake-prone areas.
