Description

Technical Field

[0001] This utility model belongs to the field of building engineering, specifically a seismic and blast-resistant steel structure wall frame and a seismic and blast-resistant wall that can accommodate pipes. Background Technology

[0002] In some modern buildings, especially in facilities requiring high earthquake and blast resistance, a double-wall structure with a steel frame and longitudinal steel chords is often used. The spacing of the longitudinal steel chords is usually designed to be 30 to 40 centimeters to form a stable skeletal structure, ensuring the wall's earthquake and blast resistance. However, when various pipes within the building (such as ventilation ducts, fire-fighting pipes, cable trays, etc.) need to pass through these walls, a thorny technical problem often arises.

[0003] Because the diameter or cross-sectional dimensions of these pipes are often larger than the spacing of the steel chords, the original longitudinal steel chords at the pipe installation locations will inevitably be cut or removed during construction. If no remedial measures are taken, this damage will severely weaken the seismic and blast resistance of the wall in that area.

[0004] Traditional methods typically involve simply plastering around the opening after pipe installation or adding basic angle steel supports at the edge. These methods only repair the surface and do not effectively compensate for or strengthen the structural strength lost due to the broken steel wires, failing to restore the original design strength of the wall and posing potential safety hazards. Therefore, there is an urgent need for a technical solution that can both meet the pipe installation requirements and effectively maintain the wall's seismic and blast resistance during pipe penetration construction. Utility Model Content

[0005] The present invention aims to solve the defects in the prior art that cause a decrease in seismic and blast-resistant strength when the steel wire is cut when the pipe passes through the wall, and provides a seismic and blast-resistant steel structure wall frame and a seismic and blast-resistant wall that can be used for pipe passage.

[0006] The technical solution of this utility model is: The seismic and blast-resistant steel structure wall frame that can accommodate pipes includes a steel frame fixed between the top and bottom surfaces of the building space, and vertical steel chords passing through the steel frame and fixedly connected to the top and bottom surfaces of the building space. Its special feature is that it also includes a pipe fixing frame, which is formed by an upper frame, a left frame, a lower frame, and a right frame. The upper frame is fixedly connected to the top surface of the building space through vertical steel chords, and the lower frame is fixedly connected to the bottom surface of the building space through vertical steel chords.

[0007] Since the relative position of the vertical steel chord and the pipe fixing bracket is not fixed, in order to facilitate the installation of the vertical steel chord at any position of the pipe fixing bracket, specifically, the upper frame and / or lower frame are made of hollow square steel, and the side of the hollow square steel facing the top or bottom surface has a groove along its length; at least one convex block is slidably arranged inside the hollow square steel, the convex block has a protruding part that can extend out of the groove, and a connector for connecting the vertical steel chord is fixed on the protruding part; the overall size of the convex block is larger than the width of the groove to prevent it from coming out of the groove.

[0008] Specifically, the upper and / or lower borders contain at least two convex blocks.

[0011] Preferably, the number of vertical steel frames between the horizontal steel frame and the bottom surface of the building space is greater than the number of vertical steel frames between the top and bottom surfaces of the building space.

[0012] Preferably, a vertical steel chord is also separately fixed between the horizontal steel frame and the top surface within the building space; Preferably, the earthquake-resistant and blast-resistant steel structure wall frame also includes horizontal steel cables perpendicular to the vertical steel cables.

[0013] Preferably, the vertical steel cable is fixedly connected to the top and bottom surfaces of the building space by expansion hooks and turnbuckles.

[0014] This utility model also provides an earthquake-resistant and blast-resistant wall that includes the above-mentioned earthquake-resistant and blast-resistant steel structure wall frame with pipe penetration capability. The earthquake-resistant and blast-resistant wall also includes a keel bonded to a vertical steel wire, a wall surface bonded to the keel, and the keel is perpendicular to the wall surface and vertically arranged.

[0015] Preferably, the keel is bonded to the vertical steel wire using a flame-retardant adhesive, and the wall surface is bonded to the keel using a flame-retardant adhesive. Each keel is bonded to the vertical steel wire using at least two adhesive blocks, with the vertical steel wire sandwiched between the keel and the adhesive blocks. The keel material is preferably the same as the wall material.

[0016] Preferably, the wall surface is formed by splicing and bonding pumice cement board or fiber cement board, and the joints of each splicing board of the wall surface are provided with caulking mesh; and / or the outer surface of the wall surface is fixed with wire mesh; and / or concrete cement or foamed concrete or concrete with added perlite or thermal insulation material or sound insulation material are poured between the wall surfaces; and / or a layer of wire mesh is built into the wall surface, and a layer of alkali-resistant glass fiber mesh is provided on both sides of the wire mesh, and the wire mesh and alkali-resistant glass fiber mesh are parallel to the wall surface; and / or, the keel (3) and the adhesive block are also fixedly connected by flat-head screws.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Example 1

[0027] The seismic and blast-resistant steel frame for pipe penetration is suitable for interior partitions and exterior walls, especially for walls exceeding 3 meters in height.

[0028] like Figure 1 As shown, the seismic and blast-resistant steel structure wall frame that can accommodate pipes in this embodiment is mainly composed of three parts: a steel frame, vertical steel chords 2, and pipe fixing brackets 6.

[0029] The steel frame serves as the main load-bearing skeleton, securely fixed between the top surface 5 and the bottom surface 7 of the building space via embedded parts. The steel frame comprises multiple vertically arranged vertical steel frames 11 and horizontally arranged horizontal steel frames 12, which are connected together by welding or other methods to form a stable grid-like support structure. Preferably, to enhance overall stability, the number of vertical steel frames 11 near the bottom surface 7 may be greater than the number between the top surface 5 and the bottom surface 7, forming a denser bottom support.

[0030] Multiple vertical steel wires 2 pass through the grid of the steel frame and are tensioned and fixed to the top surface 5 and bottom surface 7 by expansion hooks and turnbuckles. The spacing of the vertical steel wires 2 is usually designed to be 30-40 cm. They work together with the steel frame to greatly improve the wall frame's resistance to lateral displacement and blasting.

[0031] Preferably, a vertical steel chord 2 is also separately fixed between the horizontal steel frame 12 and the top surface 5 in the building space.

[0032] Preferably, the earthquake-resistant and blast-resistant steel structure wall frame also includes horizontal steel cables perpendicular to the vertical steel cables.

[0033] The pipe fixing bracket 6 consists of a rectangular steel frame, which is welded together by the top, bottom, left, and right side frames. Its size is determined according to the diameter of the pipe to be passed through, and is usually 10-20 cm larger than the outer diameter of the pipe to allow for operation and filling space.

[0034] See Figure 2 The upper and / or lower frame is made of hollow square steel 61. A continuous groove 64 is formed along the length of the hollow square steel 61 on the side facing the top surface 5 or bottom surface 7. One or more convex blocks 62 are accommodated within the cavity of the hollow square steel 61 and can slide along its length. The top of each convex block 62 has a protrusion sized to extend out of the groove 64, but the overall size of the convex block 62 is larger than the groove width to prevent it from dislodging from the groove 64. A connector 63 is fixed to this protrusion for connecting the end of the vertical steel string 2; the connector 63 is a ring or a U-shaped ring.

[0035] Installation process: 1. Pre-installation: First, according to the design drawings, install and tension the steel frame and conventional vertical steel chord 2.

[0036] 2. Positioning and Cutting: Determine the location where the pipe needs to cross, cut the vertical steel wire 2 at the crossing location, and slide the convex blocks 62 in the upper and lower frames of the pipe fixing bracket 6 so that the position of the connector 63 is roughly aligned with the direction of the nearest original design vertical steel wire 2.

[0037] 3. Install the pipe fixing bracket: Temporarily position the pipe fixing bracket 6. Connect one end of the cut vertical steel wire 2 to the connector 63 of the convex block 62, and the other end to the top surface 5 or bottom surface 7 via turnbuckles and expansion hooks. By tightening the turnbuckles, firmly fix the pipe fixing bracket 6 in the predetermined position and give it a preload force equivalent to that of the original vertical steel wire 2. At this point, the pipe fixing bracket 6 becomes a new and strong component of the wall frame.

[0038] 4. Pipe Installation: Finally, pass the pipe through the hollow portion of pipe bracket 6. Since the pipe bracket is pre-reinforced, there is no need to cut its own structure, thus perfectly avoiding the problem of weakening the wall strength. Example 2

[0039] This embodiment provides a complete wall structure including the above-mentioned steel frame: an earthquake-resistant and blast-resistant wall.

[0040] On the installed steel wall frame, firstly, adhesive blocks 4 and keels 3 are bonded to the vertical steel wires 2 using flame-retardant adhesive. Each keel 3 is fixed by at least two adhesive blocks 4 to ensure reliable connection. The keels 3 are vertically bonded to the adhesive blocks 4, perpendicular to the wall surface. The vertical steel wires 2 are sandwiched between the keels 3 and the adhesive blocks 4, and the keels 3 and adhesive blocks 4 are also fixedly connected by flat-head screws.

[0041] Subsequently, wall panels (such as fiber cement board, pumice cement board, etc.) are bonded to the keel 3 using flame-retardant adhesive, forming the two sides of the wall. The wall is formed by splicing and bonding pumice cement board or fiber cement board. To further improve the overall integrity, a jointing mesh can be pasted at the joints of each spliced ​​panel to improve the crack resistance at the joints. Preferably, a wire mesh is fixed to the outer surface of the wall. Preferably, a layer of wire mesh is embedded in the wall panel during production, and a layer of alkali-resistant glass fiber mesh is set on both sides, thereby forming a high-strength, high-toughness composite wall. The wire mesh and alkali-resistant glass fiber mesh are parallel to the surface of the pumice cement board. Preferably, the earthquake-resistant and blast-resistant wall also includes a fiber mesh that completely wraps the two wall surfaces. On this basis, white paint can be directly applied for easy subsequent construction.

[0042] The cavity between the two walls can be filled with concrete, cement, foamed concrete, or lightweight concrete with added perlite to further enhance the wall's sound insulation, fire resistance, and explosion resistance. It can be used as an interior wall or an exterior wall. When used as an exterior wall, insulation materials such as rock wool boards can be filled between the two walls; when used as an interior wall, sound insulation materials can be filled in.

[0043] During construction, the steel frame is first fixed in the building space, the vertical steel chords are fixed on the steel frame or in the building space, the keel 3 is glued to the vertical steel chord 2, and the wall is glued to the keel 3. The keel and the wall are installed by climbing each other, and the combined wall is installed.
