Description

Technical Field

[0001] This invention relates to the field of building safety protection, specifically to a movable and detachable modular explosion-proof wall. Background Technology

[0002] In the field of industrial production and protection of critical facilities, blast-resistant walls are key facilities for resisting explosive impacts and ensuring the safety of personnel and equipment, and their performance and ease of construction have attracted much attention.

[0003] Currently, fixed blast-resistant walls have significant limitations in application. Taking the fixed blast-resistant wall in standard drawing 14SG938-KBQ1 as an example, its installation requires welding or pouring foundations, a process that damages the original building structure. Furthermore, once installed, the wall cannot be reused, resulting in extremely poor flexibility. At the same time, the construction period for this type of fixed blast-resistant wall typically exceeds 8 hours, making it difficult to meet the rapid protection needs in emergency situations.

[0004] Traditional mobile blast-resistant walls also have technical shortcomings. For example, the mobile wall disclosed in patent CN112854668A relies on overall hoisting for relocation and installation, which results in poor flexibility and makes it difficult to adapt to rapid deployment in complex scenarios. More importantly, traditional mobile walls have failed to solve the problem of weldless installation in areas with dense equipment, limiting their application in areas with precision equipment.

[0005] Therefore, in areas with a high concentration of precision equipment, such as computer rooms, existing technologies cannot simultaneously meet the three core requirements: (1) weld-free construction to avoid additional damage to equipment and the site; (2) modular and quick assembly and disassembly to adapt to flexible deployment and emergency protection scenarios; and (3) explosion-proof pressure ≥100kPa to ensure sufficient protection capabilities. This technological bottleneck poses a severe challenge to explosion-proof protection in areas with high precision equipment, and a new type of explosion-proof wall technology is urgently needed to overcome the above limitations. Summary of the Invention

[0006] To address the problem that existing blast-resistant walls require welding or pouring foundations for installation, a process that damages the original building structure and results in the wall being unusable once installed, thus exhibiting extremely poor flexibility, this invention provides a modular blast-resistant wall that can be moved and disassembled.

[0007] The technical solution of this invention is:

[0008] A movable and detachable modular blast-resistant wall includes a main keel frame, a base frame, and a blast-resistant panel. The main keel frame and the base frame are connected by a horizontal insertion. A set of main keel frames and a set of base frames are connected by a modular connection to form a blast-resistant wall.

[0009] The front and rear ends of the main keel frame are respectively connected to explosion-proof panels, which cover both the front and rear ends of the main keel frame. The bottom of the main keel frame is connected to casters, and the main keel frame moves to the entrance of the base frame through the casters. The base frame is fixedly connected to the ground, and guide pulleys are installed on the base frame. The casters of the main keel frame and the guide pulleys of the base frame jointly bear the vertical load.

[0010] Furthermore, the main keel frame includes vertical keels, horizontal keels, horizontal connectors, and bolt assemblies;

[0011] A set of vertical keels are arranged in parallel longitudinal direction, and the top, middle half and bottom of each vertical keel are perpendicularly connected to the horizontal connector. The horizontal connector is used to fix the horizontal keel vertically to the vertical keel by bolt assembly to form a rectangular grid-like skeleton.

[0012] Furthermore, a rock wool layer is provided in the grid cavity formed by a set of horizontal keels and a set of vertical keels on the main keel frame. The rock wool layer is placed between the inner explosion-proof panel and the outer explosion-proof panel, so that the rock wool layer is tightly attached between the horizontal keels and the vertical keels.

[0013] The density of the rock wool layer is not less than 100 kg / m³, and the thickness of the rock wool layer is 40 mm.

[0014] Furthermore, the main keel frame also includes connecting bolts and sealing strips;

[0015] Bolt holes are reserved at the lateral edge of the main keel frame in the width direction, and after two adjacent main keel frame units are spliced ​​together, the two adjacent main keel frame units are locked and fixed by connecting bolts.

[0016] A sealing strip is embedded in the lateral edge of the main keel frame in the width direction. After two adjacent main keel frame units are locked together by connecting bolts, the sealing strip is pressed tightly. The sealing strip is installed continuously without any breaks.

[0017] Furthermore, the vertical and horizontal keels of the main keel frame are made of 40×40×3.0mm galvanized square tubes, the distance between two adjacent vertical keels is set between 4000mm and 600mm, the length of the main keel frame is 3000mm, and the height is 1800mm.

[0018] The transverse connector adopts an L-shaped corner bracket, which is made of Q235 steel and has a thickness of ≥5mm. The longitudinal wing plate of the L-shaped corner bracket is fixed to the vertical keel (101) by bolt assembly, and the horizontal wing plate of the L-shaped corner bracket is fixed to the transverse keel by bolt assembly.

[0019] Furthermore, the explosion-proof panel is made of 9.5mm thick fiber cement explosion-proof board;

[0020] The explosion-proof panel is directly fixed to both sides of the long side of the vertical and horizontal keels of the main keel frame by self-tapping screws. The distance between two adjacent self-tapping screws is less than 200mm, and the screw head of the self-tapping screw is equipped with a washer to embed the screw head of the self-tapping screw into the surface of the explosion-proof panel.

[0021] The vertical joints of two adjacent explosion-proof panels on the same side are staggered by more than 300mm, meaning that the explosion-proof panels on two adjacent main keel frames are not on the same straight line, and the gaps between two adjacent explosion-proof panels are filled with fireproof sealant.

[0022] Furthermore, the base frame includes a vertical base keel, a horizontal base keel, an upper edge keel, a lower edge keel, a vertical connector, and a grounding angle steel;

[0023] The horizontal keels of the base are arranged in parallel, and the edges and middle spacing of the horizontal keels of the base are vertically connected to the vertical keels of the base through vertical connectors. The two horizontal keels of the upper front and rear ends of the base are vertically connected to the upper edge keel through vertical connectors. The two horizontal keels of the lower front and rear ends of the base are vertically connected to the lower edge keel through vertical connectors to form the main frame. The height of the main frame is one-fifth of the height of the blast-resistant wall.

[0024] Furthermore, the base frame also includes guide pulleys;

[0025] Two guide pulleys are connected to the vertical keel of the base along the direction of the vertical keel of the base. The guide pulleys are for the movement direction of the blast-resistant wall into the base frame.

[0026] The two guide pulleys are set at the height of the horizontal keel at the bottom of the main keel frame of the blast-resistant wall and the second to last horizontal keel at the bottom. The guide pulleys are made of polyurethane and the single wheel load capacity of the guide pulleys is greater than 500 kg.

[0027] Furthermore, the lower side of the base frame has a horizontal keel with a base edge, and grounding angle steel is pre-welded to the four sides along the inner side of the horizontal keel. The horizontal surface of the grounding angle steel is fixed to the ground by expansion bolts, thereby fixing the base frame to the ground.

[0028] Furthermore, the horizontal keel of the base is made of 50×50×3.0mm galvanized square tubing;

[0029] The vertical connector adopts an L-shaped corner bracket, which is made of Q235 steel and has a thickness of ≥5mm. The longitudinal wing plate of the L-shaped corner bracket is fixed to the vertical keel of the base by bolt assembly, and the horizontal wing plate of the L-shaped corner bracket is fixed to the transverse keel of the base by bolt assembly.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] When an explosive shockwave acts on the blast-resistant panel, the impact force is transmitted to the main keel frame via self-tapping screws. The robust galvanized square tube main keel frame (especially the dense grid formed by the vertical keels and horizontal connectors) is the primary load-bearing and bending-resistant structure. The bolted angle bracket nodes primarily bear shear force under load. The high-density rock wool filling absorbs some of the impact energy and suppresses internal wall vibration. The connection and locking devices between the main keel frame modules ensure the wall maintains its integrity under impact, preventing secondary damage caused by individual modules flying out. Sealing strips ensure airtightness under non-explosive conditions.

[0032] In this invention, the vertical and horizontal keels, the base of the base frame and the keel, the explosion-proof panel and the main keel frame, and the modules are all locked together by bolts, self-tapping screws and other locking methods, which completely avoids on-site welding operations.

[0033] The main keel frame of this invention adopts a modular design. The main keel frame and the base frame are used together. The standard units are prefabricated in the factory and can be assembled on site with only simple bolt connections. It can be disassembled and assembled within 2 hours, and can be quickly deployed and flexibly configured. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0055] Specific implementation method one: Combining Figure 1 — Figure 16This embodiment describes a movable and detachable modular blast-resistant wall, which includes a main keel frame 1, a base frame 2, and a blast-resistant panel 3. The main keel frame 1 and the base frame 2 are connected by a horizontal insertion type, and a set of main keel frames 1 and a set of base frames 2 are connected by a modular type to form a blast-resistant wall.

[0056] The front and rear ends of the main keel frame 1 are respectively connected to explosion-proof panels 3, which cover both the front and rear ends of the main keel frame. The bottom of the main keel frame 1 is connected to casters 4. The main keel frame 1 moves to the entrance of the base frame 2 through the casters 4. The base frame 2 is fixedly connected to the ground. The base frame 2 is equipped with guide pulleys 5. The casters 4 of the main keel frame 1 and the guide pulleys 5 of the base frame 2 jointly bear the vertical load.

[0057] Guide pulleys 5 are fixed to the side of the vertical keel 201 of the base frame 2, with the axis of the guide pulleys 5 perpendicular to the ground; permanent casters 4 are installed at the bottom of the main keel frame 1. During construction, the main keel frame 1 moves to the base entrance via the casters 4, and the guide pulleys 5 guide it into the designed position. During service, the casters 4 and guide pulleys 5 jointly bear the vertical load, and the pulleys participate in resisting horizontal slippage during explosive impacts.

[0058] Among them, the load transfer follows a dual path:

[0059] Vertical load: from caster wheel 4 to the ground;

[0060] The horizontal load of the explosion is: from the main keel frame 1 to the guide pulley 5 shearing to the base vertical keel 201 to the ground angle steel 206 to the ground;

[0061] Each blast wall is equipped with at least three heavy-duty casters at its base. The casters have polyurethane wheels with a single wheel load capacity of more than 500 kg. The wheels of the heavy-duty casters are fixed to the base plate of the blast wall by detachable axles or bolts.

[0062] Specific Implementation Method Two: Combining Figure 1 — Figure 16 This embodiment describes a movable and detachable modular explosion-proof wall, wherein the main keel frame 1 includes vertical keels 101, horizontal keels 102, horizontal connectors 103, and bolt assemblies 104.

[0063] A set of vertical keels 101 are arranged in parallel along the longitudinal direction, and the top, middle half and bottom of each vertical keel 101 are perpendicularly connected to the horizontal connector 103. The horizontal connector is used to fix the horizontal keel 102 vertically to the vertical keel 101 by bolt assembly 104 to form a rectangular grid-like skeleton.

[0064] The vertical keel 101 is arranged in parallel in the longitudinal (height direction) direction, with a standard spacing of less than 600mm. The specific spacing can be 400mm or 500mm to determine the basic height of the blast-resistant wall.

[0065] At the top, middle, and bottom of the vertical keel 101, there are usually 1-2 horizontal connectors. The horizontal connectors 103 are usually galvanized square tubes or angle steel of the same or smaller specifications that are perpendicularly connected to the vertical keel 101.

[0066] The bolt assembly 104 uses high-strength bolts (such as M10 or M12 grade) in conjunction with the transverse connector 103 to fix the transverse keel 102 to the vertical keel 101, which forms a sturdy rectangular grid-like skeleton.

[0067] Specific implementation method three: Combining Figure 1 — Figure 16 This embodiment describes a movable and detachable modular blast-resistant wall. A rock wool layer 6 is provided in the grid cavity formed by a set of horizontal keels 102 and a set of vertical keels 101 on the main keel frame 1. The rock wool layer 6 is disposed between the inner blast-resistant panel 3 and the outer blast-resistant panel 3, so that the rock wool layer 6 is tightly attached between the horizontal keels 102 and the vertical keels 101.

[0068] The density of the rock wool layer 6 is not less than 100 kg / m³, and the thickness of the rock wool layer 6 is 40 mm.

[0069] When sound insulation, heat insulation or improved explosion resistance is required, rock wool layer 6 is filled into the grid cavity formed by the main keel frame 1. Rock wool layer 6 must be tightly filled without voids. Rock wool layer 6 is located between the inner explosion-proof panel and the outer explosion-proof panel, and is closely attached to the keel.

[0070] Specific implementation method four: Combination Figure 1 — Figure 16 This embodiment describes a movable and detachable modular explosion-proof wall, wherein the main keel frame 1 further includes connecting bolts 105 and sealing strips 106;

[0071] Bolt holes are reserved at the lateral edge of the main keel frame in the width direction, and after two adjacent main keel frame 1 units are spliced ​​together, the two adjacent main keel frame 1 units are locked and fixed by connecting bolts 105.

[0072] A sealing strip 106 is embedded in the lateral edge of the main keel frame 1 in the width direction. After two adjacent main keel frame 1 units are locked together by connecting bolts 105, the sealing strip 106 is pressed together. The sealing strip 106 is installed continuously without any breaks.

[0073] Connecting bolts 105 are installed on the lateral edge (width direction) of the unit module for quick connection of two adjacent main keel frame 1 modules. Bolt holes are usually reserved on the lateral edge (width direction) of the main keel frame 1 unit module. After the main keel frame 1 unit modules are spliced ​​in place, they are finally locked and fixed with bolts to prevent them from coming apart.

[0074] An EPDM rubber sealing strip 106 is embedded in the lateral edge (width direction) of the unit module. When the connecting bolts 105 are tightened, the sealing strip 106 is compressed to form an effective airtight barrier, so that the joints between units meet the airtightness standards such as EN12153.

[0075] Specific Implementation Method Five: Combining Figure 1 — Figure 16 This embodiment describes a movable and detachable modular explosion-proof wall. The vertical keel 101 and horizontal keel 102 of the main keel frame 1 are made of 40×40×3.0mm galvanized square tube structure. The distance between two adjacent vertical keels 101 is set between 4000mm and 600mm. The main keel frame 1 has a length of 3000mm and a height of 1800mm.

[0076] The transverse connector 103 adopts an L-shaped corner bracket, which is made of Q235 steel and has a thickness of ≥5mm. The longitudinal wing plate of the L-shaped corner bracket is fixed to the vertical keel (101) by bolt assembly 104, and the horizontal wing plate of the L-shaped corner bracket is fixed to the transverse keel 102 by bolt assembly 104.

[0077] Specific Implementation Method Six: Combination Figure 1 — Figure 16 This embodiment describes a movable and detachable modular explosion-proof wall, wherein the explosion-proof panel 3 is made of 9.5mm thick fiber cement explosion-proof board;

[0078] The explosion-proof panel 3 is directly fixed to the long sides of the vertical keel 101 and the horizontal keel 102 of the main keel frame 1 by self-tapping screws 301. The distance between two adjacent self-tapping screws 301 is less than 200mm, and the screw head of the self-tapping screw 301 is equipped with a washer, so that the screw head of the self-tapping screw 301 is embedded in the surface of the explosion-proof panel 3.

[0079] The vertical joints of two adjacent explosion-proof panels 3 on the same side are staggered by more than 300mm, meaning that the explosion-proof panels 3 on two adjacent main keel frames 1 are not on the same straight line, and the gaps between two adjacent explosion-proof panels 3 are filled with fireproof sealant.

[0080] The explosion-proof panels adopt a double-sided covering form, that is, explosion-proof panels 3 are installed on both the inner and outer sides of the main keel frame 1. The explosion-proof panels 3 are 9.5mm thick fiber cement explosion-proof boards, and the explosion-proof panels 3 meet the relevant explosion-proof standards.

[0081] The explosion-proof panel 3 is fixed by using self-tapping screws 301 (rust-proofed, such as galvanized or stainless steel) to directly fix the panel 3 to the vertical keel 101 and the horizontal keel 102. The spacing of the self-tapping screws 301 is strictly less than 200mm (usually denser at the edges and evenly distributed in the middle), and the screw heads need to be recessed into the panel surface or a washer needs to be added.

[0082] For the joint treatment of explosion-proof panels 3, the vertical joints of adjacent explosion-proof panels 3 must be staggered by more than 300mm (i.e., the panel joints on adjacent keels are not on the same straight line) to avoid forming a continuous weak line. The gaps between panels can be filled with fireproof sealant.

[0083] Specific implementation method seven: Combination Figure 1 — Figure 16 This embodiment describes a movable and detachable modular explosion-proof wall. The base frame 2 includes a base vertical keel 201, a base horizontal keel 202, an upper edge keel 203, a lower edge keel 204, a vertical connector 205, and a grounding angle steel 206.

[0084] The horizontal keels 202 of the base are arranged in parallel, and the edges and middle spacing of the horizontal keels 202 of the base are vertically connected to the vertical keels 201 of the base through vertical connectors 205. The two horizontal keels 202 of the upper front and rear are vertically connected to the upper edge keel 203 through vertical connectors 205. The two horizontal keels 202 of the lower front and rear are vertically connected to the lower edge keel 203 through vertical connectors 205 to form the main frame, and the height of the main frame is one-fifth of the height of the blast-resistant wall.

[0085] At the edges and middle (spacing not exceeding 800mm) of the horizontal keel 202 of the base, vertical connectors 205 (usually galvanized square tubes or angle steel of the same or smaller specification) are perpendicularly connected to the horizontal keel 202 of the base. The connection method is to use high-strength bolts (such as M10 or M12 grade) to fix the vertical connectors 205 to the horizontal keel 202 of the base, which forms a sturdy rectangular grid-like skeleton.

[0086] Multiple base frames 2 can be extended by means of I-type brackets 8. Bolts are passed through the holes of the I-type brackets 8 and fixed in the vertical direction on the side connecting edge of the horizontal keel 202 of the base of the base frame 2, thereby realizing the extension of multiple base frames 2.

[0087] Specific implementation method eight: Combination Figure 1 — Figure 16 This embodiment describes a movable and detachable modular explosion-proof wall, wherein the base frame 2 further includes guide pulleys 5;

[0088] Two guide pulleys 5 are connected to the vertical keel 201 of the base along the direction of the vertical keel 201 of the base. The guide pulleys 5 are the direction of movement of the explosion-proof wall into the base frame 2.

[0089] The two guide pulleys 5 are set at the same height as the horizontal keel 102 at the bottom of the main keel frame 1 on the blast-resistant wall body and the second to last horizontal keel 102 at the bottom. The guide pulleys 5 are made of polyurethane and the single wheel load capacity of the guide pulleys 5 is greater than 500kg.

[0090] Specific Implementation Method Nine: Combining Figure 1 — Figure 16 This embodiment describes a movable and detachable modular explosion-proof wall. The lower side of the base frame 2 has a base horizontal keel 202, and grounding angle steel 206 is pre-welded to the four sides along the inner side of the base horizontal keel 202. The horizontal surface of the grounding angle steel 206 is fixed to the ground by expansion bolts 7, thereby fixing the base frame 2 to the ground.

[0091] Specific Implementation Method Ten: Combining Figure 1 — Figure 16 This embodiment describes a movable and detachable modular explosion-proof wall, wherein the base horizontal keel 202 is made of 50×50×3.0mm galvanized square tubing;

[0092] The vertical connector 205 adopts an L-shaped angle bracket, which is made of Q235 steel and has a thickness of ≥5mm. The longitudinal flange of the L-shaped angle bracket is fixed to the vertical keel 201 of the base by bolt assembly 104, and the horizontal flange of the L-shaped angle bracket is fixed to the transverse keel 202 of the base by bolt assembly 104.

[0093] Key steps in the construction method:

[0094] (1) Base frame installation:

[0095] Lay the base frame 2 according to the positioning line. The vertical keel 201 of the base frame is pre-installed with guide pulleys 5 (height 200mm from the top surface of the base, spacing ≤800mm).

[0096] Expansion bolt 7 is used to pre-fix the grounding angle steel 206, and 20mm adjustment allowance is reserved for expansion bolt 7.

[0097] (2) The main keel frame is pushed into place:

[0098] Keep the casters (4) in place, push the main keel frame 1 to the entrance of the base frame 2, and manually push the main keel frame 1 along the guide pulley 5 (thrust ≤ 400N) until the positioning block is reached;

[0099] (3) Base closure and collaborative load bearing:

[0100] The horizontal keel 202 of the base of the enclosed base frame 2 is installed, and the vertical connector 205 is finally tightened to 80Nm by bolts;

[0101] Caster 4 on the ground: Adjust the leveling bolts on the base of caster 4 so that caster 4 and guide pulley 5 are in contact with the ground together (load distribution ratio 1:1).

[0102] Finally, tighten the grounding angle steel (206) and expansion bolts to 7 to 80 Nm.

[0103] (4) Module assembly and testing:

[0104] The bolts of the lateral connectors of the adjacent main keel frame 1 modules are simultaneously tightened to 100 Nm;

[0105] With the 4 casters braked and locked, a static load of 600 kg / wheel was applied to test the settlement (≤1 mm).
