Description

Technical Field

[0001] The invention relates to the field of explosion-resistant and penetration-resistant assembled steel structures, and in particular to an assembled wall structure and an assembled explosion-resistant building with embedded low-yield point corrugated steel plates for deep-sea islands and reefs. Background Art

[0002] The walls of conventional prefabricated buildings have certain explosion resistance and corrosion resistance, but the environment of deep-sea islands and reefs is harsh and the region is sensitive, so prefabricated walls need to have higher explosion resistance, penetration resistance, corrosion resistance and other properties to cope with the harsh environment. The general prefabricated steel structure wall structure has only one layer, and the explosion resistance and corrosion resistance can only cope with the mainland environment. When facing some long-term tasks in deep-sea islands and reefs, ordinary prefabricated steel structure buildings cannot meet them. The prefabricated walls combined with multiple layers of steel plates improve their convenience and high load-bearing capacity. According to the above conditions and environment required for prefabricated walls in deep-sea islands and reefs, in order to ensure the living force in wartime and provide long-term and stable protection to better meet various combat requirements, it is imperative to study the combination and improvement of the explosion resistance, penetration resistance, rapidity and corrosion resistance of prefabricated walls. Summary of the invention

[0003] In view of the shortcomings of the prior art, the main purpose of the present invention is to provide an assembled wall structure with embedded low-yield point corrugated steel plates for deep-sea islands and reefs, so as to solve the problem that conventional walls in the prior art have poor performance in explosion resistance, penetration resistance, corrosion resistance, etc., and are difficult to cope with the harsh environment on deep-sea islands and reefs.

[0004] The technical solution of the present invention is as follows:

[0006] The outer wall panel is formed by butt welding at least two first stiffening steel plates along the height direction thereof;

[0019] A plurality of bolts, evenly mounted on the support plate, adapted to pass through the inner wall plate and be fixed by nuts;

[0020] The connecting rod has one end which is welded and fixed to the support plate, and the other end which is welded and fixed to the tail of one of the special-shaped fixed ends.

[0021] Preferably, the assembled wall structure further includes a first weld reinforcement device, which is arranged at the weld position of two adjacent first stiffening steel plates, and the first weld reinforcement device includes:

[0022] L-shaped steel members, each two forming a group, are transversely symmetrically arranged on both sides of the weld, and the multiple groups of L-shaped steel members are evenly arranged along the height direction of the first stiffening steel plate;

[0023] A plurality of steel sleeves are provided, each of which is sleeved and fixed on each group of L-shaped steel components;

[0024] The vertical steel bars are vertically symmetrically arranged on both sides of the plurality of steel sleeves and are respectively welded and fixed to the adjacent steel sleeves.

[0029] The present invention also proposes an assembled explosion-proof building for deep-sea islands and reefs, comprising at least two layers of wall frames, each layer of wall frames being formed by enclosing and connecting a plurality of the above-mentioned assembled wall structures.

[0030] Preferably, the top of the inner side of each prefabricated wall of one layer of the two wall frames is welded with a shear groove, and the bottom of the inner side of each prefabricated wall of the other layer of the wall frames is welded with a shear key, and the two layers of the wall frames are fixed by inserting the shear keys into the shear grooves.

[0031] The beneficial effect of the present invention compared with the prior art is that the present invention proposes an assembled wall structure with embedded low-yield point corrugated steel plates for deep-sea islands and reefs. The wall has the advantages of fast assembly speed, strong explosion resistance, anti-penetration and marine corrosion resistance, and is suitable for deep-sea islands and reefs.

[0032] The outer wall panels and inner wall panels of the present invention are both composed of stiffened steel plates, which are connected by butt welding along the height direction, thereby enhancing the overall rigidity and stability of the wall. At the same time, the wall can maintain the integrity and stability of the structure when subjected to the complex environmental pressure of deep-sea islands and reefs, thereby improving the bearing capacity of the wall.

[0033] The outer wall panels and the inner wall panels of the present invention are welded on site using divided stiffening steel plates, which are convenient for installation of components such as internal interlayer corrugated steel plates, transportation, and replacement of wall components after damage.

[0034] The outer wall panels of the present invention adopt corrosion-resistant high-strength weathering steel plates, ensuring that the outer wall panels can withstand both large external loads and corrosion and weathering caused by long-term exposure to the external environment, and are not prone to cracks and breaks.

[0035] The inner wall panel of the present invention adopts a high-strength steel plate, which can provide further support for the outer wall panel, thereby preventing the wall from being deformed or damaged under the action of load.

[0036] The present invention arranges two interlayer corrugated steel plates between the outer wallboard and the inner wallboard. The corrugated steel plates have a high out-of-plane stiffness due to their unique wave structure. When the two interlayer corrugated steel plates are arranged between the outer wallboard and the inner wallboard with their crests facing each other and their troughs facing each other, they together form a more stable structural system. This design can significantly improve the lateral stiffness of the wall, enabling it to better resist wind loads and earthquake loads.

[0037] The corrugated structure of the sandwich corrugated steel plate of the present invention can deform when subjected to force, thereby absorbing and dissipating energy. The energy dissipation cavity formed between the two sandwich corrugated steel plates and the energy absorbing and shock absorbing material filled therein further enhance the energy dissipation capacity of the wall. In extreme cases such as earthquakes, this energy dissipation mechanism can effectively reduce the damage to the wall and improve the seismic performance of the wall.

[0038] In the present invention, the energy-absorbing cavity composed of the wave structure and the double-layer corrugated steel plate and the energy-absorbing and shock-absorbing material filled with gaps can absorb the noise transmitted by the explosion and absorb the structural vibration caused by the explosion.

[0039] The invention can arrange pipeline facilities such as strong and weak current pipes and water pipes in the horizontal gaps between the sandwich corrugated steel plate and the outer wall plate and the inner wall plate.

[0040] The present invention can conveniently clamp and fix two interlayer corrugated steel plates by arranging multiple corrugated steel plate fixing devices, and at the same time, the clamps of the corrugated steel plate fixing devices are tightly attached to the interlayer corrugated steel plates. When the explosion shock wave acts on the wall, the sliding friction generated after the deformation of the clamps and the interlayer corrugated steel plates will dissipate energy, thereby reducing the impact damage of the explosion on the wall, and further improving the explosion resistance of the wall.

[0041] The present invention adopts an assembled design, and the clamps and the interlayer corrugated steel plates can be easily installed and disassembled, which reduces the construction difficulty and cost, and also improves the maintainability and replaceability of the wall.

[0069] The implementation of the present invention is described in detail below in conjunction with preferred embodiments.

[0070] like Figures 1 to 7 As shown, the present invention proposes an assembled wall structure with embedded low-yield point corrugated steel plates for deep-sea islands and reefs. The assembled wall structure 100 includes an outer wall panel 1, an inner wall panel 2, a sandwich corrugated steel plate 3, an energy-absorbing and shock-absorbing material (not shown in the figure), and a corrugated steel plate fixing device 4.

[0071] See also Figure 1 , Figure 2 The outer wall panel 1 is located at the outermost layer of the assembled wall structure 100, and is formed by butting and splicing at least two first stiffening steel plates 101 along the outermost edges in the height direction, and then welding them together. It is easy to understand that each outer wall panel 1 can be welded by two, three or more first stiffening steel plates 101 according to the length requirements. The present invention is preferably two.

[0072] In the present invention, the first stiffening steel plate 101 is a corrosion-resistant high-strength weathering steel plate, that is, weathering steel. Weathering steel is a low-alloy high-strength steel made by adding a small amount of alloy elements (such as copper, nickel, chromium, phosphorus, etc.) to ordinary carbon steel. This type of steel is between ordinary steel and stainless steel. It has the strength and toughness of ordinary steel and some corrosion resistance of stainless steel. The first stiffening steel plate 101 is made of corrosion-resistant high-strength weathering steel plate to ensure that the outer wall panel 1 can withstand large external loads while being able to withstand corrosion and weathering in the external environment for a long time, and is not prone to cracks and fractures.

[0073] Furthermore, the first stiffening steel plate 101 is a corrosion-resistant Q420 high-strength weathering steel plate. The yield strength of the first stiffening steel plate reaches 420MPa, which belongs to the category of high-strength steel plates and has high bearing capacity and deformation resistance. This enables the steel plate to maintain the integrity and stability of the structure when subjected to a large load, thereby ensuring the safety and reliability of the structure. Of course, the first stiffening steel plate can also increase the yield strength according to specific building needs, and select other materials such as corrosion-resistant Q460 high-strength weathering steel plates or corrosion-resistant Q500 high-strength weathering steel plates.

[0074] In some embodiments, an I-shaped steel rib 7 (or an L-shaped steel rib or the like) is provided on the first stiffening steel plate 101, and the I-shaped steel rib 7 is uniformly welded on the inner side of the first stiffening steel plate 101. The I-shaped steel rib 7 can significantly improve the rigidity of the outer wall panel 1, making the structure more stable when subjected to external forces, and less prone to deformation or instability.

[0075] In some embodiments, the weld positions of the two first stiffening steel plates 101 of the outer wall panel 1 are provided with first weld reinforcement devices 5. By adding the first weld reinforcement device 5, the outer wall panel 1 can significantly enhance the strength, toughness and shear resistance of the weld position, optimize the stress distribution in the wall panel structure, avoid cracking or damage of the weld caused by stress concentration, and make the outer wall panel 1 more able to withstand external loads and deformation pressure, thereby improving the bearing capacity of the entire wall panel structure.

[0076] Continue to see Figure 2 The first weld reinforcement device 5 includes an L-shaped steel member 501, a steel sleeve 502 and a vertical steel bar 503. The L-shaped steel member 501 is provided with multiple groups, and the multiple groups of L-shaped steel members 501 are evenly arranged along the height direction of the first stiffening steel plate 101. Each group includes two L-shaped steel members 501, and the two L-shaped steel members 501 are transversely symmetrically arranged on both sides of the weld position of the two first stiffening steel plates 101. Each L-shaped steel member 501 is welded by a transverse steel plate and a vertical steel plate, and the transverse steel plates of the two L-shaped steel members 501 are vertically welded and fixed to the first stiffening steel plate 101, and the vertical steel plates are arranged opposite to the first stiffening steel plate 101. There are multiple steel sleeves 502, and each sleeve 502 is suitable for being sleeved and fixed on the vertical steel plates of the two L-shaped steel members 501 of each group of L-shaped steel members 501. Two vertical steel bars 503 are provided, which are vertically symmetrically arranged on both sides of the plurality of steel sleeves 502 and are respectively welded and fixed to adjacent steel sleeves 502 .

[0077] The vertical steel bar 503 can also be spot welded to the edge of the first stiffening steel plate 101 after the steel sleeve 502 is installed, so as to fix the steel sleeve 502 .

[0078] In the present invention, the L-shaped steel member 501 is prefabricated and installed, and then directly nested by the steel sleeve 502, which is convenient for installation and improves the construction speed; after the outer wall panel 1 is slightly damaged and deformed, the outer wall panel 1 can be restored by a certain repair method, and can be continued to be used by replacing the steel sleeve 502 and the L-shaped steel member 501. In addition, according to the needs of different building use environments, the yield strength of the steel sleeve 502 can be replaced to further meet the required bearing capacity of the building. In addition, the installed vertical steel bar 503 can play a certain vertical stiffening rib effect, assisting the wall panel to resist the load and improving the overall bearing capacity of the building.

[0079] In some embodiments, the sleeve 502 is a rectangular sleeve with a strip hole in the middle thereof, suitable for being fixed on the vertical steel plate of the L-shaped steel member 501 through the strip hole.

[0080] In the present invention, the vertical steel bar 503 is a rectangular steel bar having the same height as the first stiffening steel plate 101 .

[0081] See also Figure 1 , Figure 3 The inner wall panel 2 is located on the inner side of the assembled wall structure 100, and is formed by butting and splicing at least two second stiffening steel plates 201 along the outermost edges in the height direction, and then welding them together. Each inner wall panel 2 can be welded by two, three or more second stiffening steel plates according to the length requirements. The present invention is preferably two.

[0082] In the present invention, the second stiffening steel plate 201 is a high-strength steel plate. The high-strength steel plate is obtained through a special production process and alloying treatment, and its yield point and tensile strength are significantly higher than those of ordinary steel. The second stiffening steel plate 201 is a high-strength steel plate, which can provide further support for the outer wall panel 1, thereby preventing the wall panel from being deformed or damaged under load.

[0083] Furthermore, the second stiffening steel plate 201 is a Q420 high-strength steel plate. The yield strength of the second stiffening steel plate 201 reaches 420MPa, which belongs to the category of high-strength steel plate and has high bearing capacity and anti-deformation ability. This enables the steel plate to maintain the integrity and stability of the structure when subjected to a large load, thereby ensuring the safety and reliability of the structure.

[0084] In some embodiments, an I-shaped steel rib 7 (or an L-shaped steel rib or the like) is provided on the second stiffening steel plate 201, and the I-shaped steel rib 7 is uniformly welded on the inner side of the second stiffening steel plate 201. The I-shaped steel rib 7 can significantly improve the rigidity of the inner wall panel 2, making the structure more stable when subjected to external forces, and less prone to deformation or instability.

[0085] In some embodiments, the weld positions of the two second stiffening steel plates 201 of the inner wall panel 2 are provided with second weld reinforcement devices 6. By adding the second weld reinforcement device 6, the inner wall panel 2 can significantly enhance the strength, toughness and shear resistance of the weld position, optimize the stress distribution in the wall panel structure, avoid cracking or damage of the weld caused by stress concentration, and enable the inner wall panel 2 to assist the outer wall panel 1 in bearing external loads and deformation pressure, thereby improving the bearing capacity of the entire wall panel structure.

[0086] Continue to see Figure 3 The second weld reinforcement device 6 includes an L-shaped rib 601 and a connecting steel plate 602. There are two L-shaped ribs 601, and their length is the same as the height of the second stiffening steel plate 201. The two L-shaped ribs 601 are symmetrically arranged on both sides of the weld positions of the two second stiffening steel plates 201, and the web (vertical steel plate) of each L-shaped rib 601 is vertically welded and fixed to the second stiffening steel plate 201, and the flange plate (transverse steel plate) of each L-shaped rib 601 is arranged toward one side of the weld. There are multiple connecting steel plates 602, and the multiple connecting steel plates 602 are evenly arranged on the outside of the flange plates of the two L-shaped ribs 601 along the height direction of the second stiffening steel plate 201, and are bolted and fixed to the flange plates of the two L-shaped ribs 601.

[0087] In the present invention, the connecting steel plate 602 is connected to the L-shaped rib 601 by bolts, which is convenient for installation, reinforcement and replacement after damage; at the same time, the vertically arranged L-shaped rib 601 and the horizontally arranged connecting steel plate 602 can better withstand the load in all directions, and the L-shaped rib 601 can improve the bearing capacity of the wall panel. And the connecting steel plates 602 with different yield strengths can be replaced according to the building bearing requirements.

[0088] Specifically, each connecting steel plate 602 is provided with two groups of bolt holes on the flange plates corresponding to the two L-shaped ribs 601 on both sides of the weld, and the flange plates of the two L-shaped ribs 601 are provided with the same holes corresponding to one group of bolt holes, which are suitable for connecting the connecting steel plate 602 and the two L-shaped ribs 601 on both sides of the weld by means of bolt groups passing through the corresponding holes.

[0089] See also Figure 1 There are two interlayer corrugated steel plates 3, which are arranged between the outer wallboard 1 and the inner wallboard 2, and the crests are opposite to each other, and the troughs are opposite to each other. The wave structure of the interlayer corrugated steel plate 3 of the present invention can be deformed when subjected to force, thereby absorbing and dissipating energy.

[0090] An energy-absorbing cavity 301 is formed between the troughs of the two interlayer corrugated steel plates 3, and the energy-absorbing and shock-absorbing material is filled in the energy-absorbing cavity 301. The design of the energy-absorbing cavity 301 and the energy-absorbing and shock-absorbing material can absorb and disperse the shock wave energy generated by the explosion. When an explosion occurs, the shock wave will impact the wall, and the energy-absorbing and shock-absorbing material in the energy-absorbing cavity 301 can effectively absorb this energy, reduce its direct impact on the wall, and improve the explosion-proof performance of the building. At the same time, the cavity structure and the energy-absorbing and shock-absorbing material can effectively absorb the noise generated by the explosion and reduce the damage caused by the noise.

[0091] In the present invention, the energy absorbing and shock absorbing material can be foamed aluminum, or other energy absorbing materials with cavities, which can be combined with the energy dissipation cavity to achieve the effect of sound absorption and shock reduction.

[0092] The corrugation direction of the two interlayer corrugated steel plates 3 is consistent with the height direction of the assembled wall, that is, the interlayer corrugated steel plates 3 are placed in a horizontal manner. Since the corrugated steel plate has a wavy cross-section, this shape can more effectively resist horizontal forces (such as wind force, earthquake force, etc.). When the corrugation direction is arranged along the height direction of the wall, it is like a series of springs or dampers, which can absorb and disperse horizontal forces, thereby improving the building's lateral resistance. At the same time, the horizontal arrangement of the corrugated steel plates can increase the rigidity of the structure, thereby reducing the natural vibration period and making the structure more stable when subjected to external forces.

[0093] The sandwich corrugated steel plate 3 is a low yield strength corrugated steel plate. The low yield point can ensure that the sandwich corrugated steel plate 3 deforms and consumes energy before the outer wallboard 1 and the inner wallboard 2 reach yield.

[0094] In some embodiments, the interlayer corrugated steel plate 3 is a Q345 low yield strength corrugated steel plate.

[0095] In the present invention, the yield strength of the sandwich corrugated steel plate 3 is lower than the yield strength of the outer wallboard 1 and the inner wallboard 2. The yield strength lower than the inner and outer wallboards can ensure that the corrugated steel plate can reach the working condition of energy consumption before the inner and outer wallboards are damaged, which has the advantage of being easier to deform and having better energy absorption and energy consumption effects. Steels with other yield points can be replaced according to the needs of the building to better adapt to explosion-proof work.

[0096] It is easy to understand that high strength and low yield are relative terms. High strength means that compared with traditional steel, high-strength steel plates have higher yield strength and tensile strength, and the inner and outer wall panels can better withstand larger explosion impacts; the purpose of low yield is to stagger the yield points of the inner and outer wall panels and the corrugated steel plates, and to ensure that the corrugated steel plates deform before the inner and outer wall panels, so as to absorb and consume energy.

[0097] In some embodiments, the gaps between each interlayer corrugated steel plate 3 and the outer wall panel 1 and the inner wall panel 2 are filled with thermal insulation materials to cope with the changeable weather of deep-sea islands and reefs.

[0098] Continue to see Figure 1 There are multiple corrugated steel plate fixing devices 4, and the multiple corrugated steel plate fixing devices 4 are evenly arranged on the two interlayer corrugated steel plates 3, which are used to clamp and fix the two interlayer corrugated steel plates 3.

[0099] Each corrugated steel plate fixing device 4 includes a set of clamps, which are symmetrically arranged on both sides of the positions where the wave crests of the two interlayer corrugated steel plates 3 are in close contact with each other. One side of the set of clamps is in close contact with the wave crest of one of the layer corrugated steel plates 3, and the other side is respectively connected to the outer wallboard 1 and the inner wallboard 2. The present invention makes the clamps of the corrugated steel plate fixing device 4 close to the interlayer corrugated steel plate 3. When the explosion shock wave acts on the wall, the sliding friction generated after the deformation of the clamp and the interlayer corrugated steel plate 3 and the sliding friction between the two interlayer corrugated steel plates will dissipate energy, thereby reducing the impact damage of the explosion on the wall, and then improving the explosion resistance of the wall.

[0100] In some embodiments, see Figure 4 , Figure 5 The set of clamps includes two special-shaped fixed end heads 401, and the heads of the two special-shaped fixed end heads 401 are arc-shaped surfaces, which match the crest shape of the interlayer corrugated steel plate 3 and are suitable for tightly fitting with the crest of the interlayer corrugated steel plate 3.

[0101] Continue to see Figure 4 , Figure 5 , each corrugated steel plate fixing device 4 also includes a fixed support 402, a bolt connecting rod 403 and an adjusting nut 404. The fixed support 402 is arranged on the side of one of the special-shaped fixed ends 401 close to the inner wall panel 2, and is fixed to the inner wall panel 2 by bolts. Specifically, the fixed support 402 is composed of a support plate 4021, a bolt 4022 and a connecting rod 4023. The support plate 4021 is a rectangular steel plate, suitable for abutting against the inner wall panel 2; there are multiple bolts 4022, for example, four, evenly installed on the support plate 4021, suitable for passing through the inner wall panel 2 and fixed by nuts; one end of the connecting rod 4023 is welded and fixed to the side of the support plate 4021 away from the bolt 4022, and the other end is welded and fixed to the tail of one of the special-shaped fixed ends 401.

[0102] The bolt connecting rod 403 is arranged on one side of the other special-shaped fixing end 402 close to the outer wall panel 1 . One end of the bolt connecting rod 403 is rotatably connected to the tail of the other special-shaped fixing end 401 , and the other end is suitable for passing through the outer wall panel 1 .

[0103] There is at least one adjusting nut 404 , which is sleeved on the bolt connecting rod 403 and fixed to the outer wall panel 1 by welding.

[0104] In the present invention, most of the length of the bolt connecting rod 403 is set on the outside of the outer wall panel 1. By rotating the bolt connecting rod 403, the bolt connecting rod 403 can be moved along the thread direction of the adjusting nut 404 to extend or shorten the length of the bolt connecting rod 403 on the inside of the outer wall panel 1, thereby achieving the clamping or loosening of the interlayer corrugated steel plate 3 by the special-shaped fixed end 402.

[0105] In some embodiments, the connecting rod 4023 is a round steel rod.

[0106] In some embodiments, two adjusting nuts 404 may be provided, one is welded and fixed along the inner side of the outer wall panel 1, and the other is welded and fixed along the outer side of the outer wall panel 1, so that the bolt connecting rod 403 passes through the two adjusting nuts 404 at the same time. This has the following advantages: first, the moment bearing capacity of the bolt connecting rod 403 is improved. If there is only one adjusting nut 404 on the inner side of the outer wall, the bolt connecting rod 403 is easy to shake when it is subjected to periodic bending moment (bending moment of the bending rod); second, after tightening the bolt connecting rod 403, the spiral range is doubled, the force transmission range of the connecting rod is increased, and the bearing capacity of the bolt connecting rod 403 along the rod direction is improved; third, the contact area between the bolt connecting rod 403 and the air is reduced, and the rust of the connecting rod is slowed down.

[0107] It is easy to understand that the rotational connection between one end of the bolt connecting rod 403 and the tail of the other special-shaped fixed end 401 can be achieved by providing a groove at the end of one end of the bolt connecting rod 403, and providing a protrusion at the tail of the special-shaped fixed end 401, wherein the cross-sectional size of the protrusion is larger than the notch size of the groove, so that the protrusion cannot slide out of the notch of the groove when installed in the groove, that is, the bolt connecting rod 403 can only rotate along the special-shaped fixed end 401, and cannot be separated from the special-shaped fixed end 401. Of course, the rotational connection between the bolt connecting rod 403 and the special-shaped fixed end 401 is not limited to the above-mentioned groove and protrusion design. In practical applications, a variety of other effective mechanical connection means can also be used to achieve the same purpose.

[0108] Before the corrugated steel plate fixing device 4 of the present invention is used to clamp two interlayer corrugated steel plates 3, the fixing support 402 and one of the special-shaped fixing ends 401 have been welded and fixed, and the bolt connecting rod 403 and the other special-shaped fixing end 401 have also been connected. When the corrugated steel plate fixing device 4 is in use, the head of the special-shaped fixed end head 401 with the fixed support 402 is first pressed against the wave crest of one of the sandwich corrugated steel plates 3, and then the fixed support 402 is bolted and fixed to the inner wall panel 2, and then the adjusting nut 404 is correspondingly welded to the outer wall panel 1, and then the special-shaped fixed end head 401 with the bolt connecting rod 403 is passed through the outer wall panel 1 and bolted to the adjusting nut 404 through the bolt connecting rod 403, and then the head of the special-shaped fixed end head 401 with the bolt connecting rod 403 is placed directly against the wave crest of another sandwich corrugated steel plate 3, and finally the bolt connecting rod 403 is rotated to make the head of the special-shaped fixed end head 401 with the bolt connecting rod 403 move to press against the wave crest of another sandwich corrugated steel plate 3, and work together with the head of the special-shaped fixed end head 401 with the fixed support 402 to clamp the two sandwich corrugated steel plates 3.

[0109] In the present invention, the wall (outer wall panel and inner wall panel) on which the corrugated steel plate fixing device is installed is assembled from the inside to the outside, and the wall steel plate is disconnected, so when the special-shaped fixing end of the inner wall is installed, the two sandwich corrugated steel plates can be fixed together through the window hole, and then the sandwich corrugated steel plate is embedded in the special-shaped fixing end of the inner wall by manual operation, and then the outer wall panel is installed in blocks (for example, half of the outer steel plate is installed first, and the corrugated steel plate is temporarily fixed at the notch of the other half by manual operation, and after half of the outer wall panel is installed, the corrugated steel plate is clamped by the special-shaped fixing end of the outer wall, and then the other outer wall panel is installed at this time, to ensure that the corrugated plates will not shift relative to each other during installation), to ensure that the wall is installed tightly and accurately enough.

[0110] See also Figures 6 to 9 The present invention also proposes an assembled explosion-proof building for deep-sea islands and reefs. The building is composed of at least two layers of wall frames 100a overlapped and connected, and each layer of wall frames 100a is enclosed and connected by four pieces of the above-mentioned assembled wall structures 100. In the present invention, this building structure is unique, has excellent explosion-proof performance and convenient assembly, and is very suitable for rapid construction on remote and harsh deep-sea islands and reefs.

[0111] In some embodiments, the upper and lower wall frames 100a are connected by shear-resistant connecting members to improve the shear resistance.

[0112] In some embodiments, see Figure 6 , Figure 8The upper wall frame is located at the top of the two wall frames 100a, and the lower wall frame is located at the bottom. The inner bottom of the upper wall frame is welded with a shear key 8, that is, at least one shear key 8 is welded at the inner bottom of each assembled wall structure 100 constituting the upper wall frame; the inner top of the lower wall frame is welded with a shear groove 9, that is, at least one shear groove 9 is welded at the inner top of each assembled wall structure 100 constituting the lower wall frame. The upper and lower adjacent wall frames 100a are fixed by inserting the shear key 8 into the shear groove 9. The connecting key 8 is inserted into the shear groove 9 to form a bolt structure, which strengthens the connection between the upper and lower wall frames 100a, improves the shear resistance of the overall building, and facilitates the installation of the assembled wall.

[0113] It is easy to understand that after the upper and lower adjacent wall frames 100a are fixed by inserting the shear keys 8 into the shear grooves 9, welding connections are still required between the upper and lower adjacent wall frames 100a to improve the overall stability of the building.

[0114] In some embodiments, the shear key 8 is a vertical steel plate, the shear groove 9 is a hollow groove steel plate, and the width of the vertical steel plate is adapted to the groove width of the hollow groove steel plate and is suitable for being inserted into the groove.

[0115] In some embodiments, a vertical seam of a certain length is provided at the vertical middle position of the outer wallboard 1 and the inner wallboard 2 of each assembled wall structure 100 to reduce temperature stress. Round holes are cut at the four corners of each assembled wall structure 100 and at the joints of adjacent walls to reduce stress concentration.

[0116] In the present invention, the welding seam positions of the outer wall panel 1 and the inner wall panel 2 of each prefabricated wall structure 100, the welding seam positions of the outer wall panels 1 and the outer wall panels 1 of the upper and lower prefabricated wall structures 100, and the welding seam positions of the inner wall panels 2 and the inner wall panels 2 are staggered with each other to improve the bearing capacity of the building.

[0117] See also Figures 6 to 9 At least one assembled wall structure 100 of each layer of the wall frame 100a is provided with a window hole 10, and each of the four corners of the window hole 10 is provided with a crack stop hole 11. The crack stop hole 11 is a small hole provided at a place where stress is easily concentrated (such as the four corners of the window hole 10), which is intended to prevent cracks from extending and expanding from these high stress areas. By destroying the continuity of crack expansion, the crack stop hole 11 can significantly improve the overall crack resistance of the wall.

[0118] See also Figure 6 , Fig. 9 At least one assembled wall structure 100 of the first layer wall frame 100a of the first floor is provided with a door opening 12. The door opening 12 is partially reinforced around to reduce stress concentration.

[0119] In the present invention, the window opening 10 is installed with explosion-proof glass, and the door opening 12 is installed with an explosion-proof door.

[0120] In some embodiments, see Figure 6 , Figure 7 The building further includes a hollow steel column 200 and a hollow square steel beam 300. The hollow steel column 200 is arranged at the corners of two adjacent assembled wall structures 100, and the hollow square steel beam 300 is arranged between two adjacent hollow steel columns 200 to form a stable frame system with the hollow steel column 200.

[0121] In some embodiments, see Figure 1 , Figure 3 The building further comprises a fishtail steel plate 400, which is welded to the edge of the inner wall panel 2 of the adjacent prefabricated wall structure 100 corresponding to each hollow steel column 200, and is suitable for being welded and fixed to the inner wall panel 2. And / or, the fishtail steel plate 400 is welded to the edge of the inner wall panel 2 of the adjacent prefabricated wall structure 100 corresponding to each hollow square steel beam 300, and is suitable for being welded and fixed to the inner wall panel 2.

[0122] The setting of the fishtail steel plate 400 can expand the contact area between the inner wall panel 2 and the hollow steel column 200 and / or the hollow square steel beam 300, increase the force transmission path of the inner wall panel 2; at the same time, make the connection between the prefabricated wall structure 100 and the hollow steel column 200 and / or the hollow square steel beam 300 more secure.

[0123] In the present invention, the outer wall panel 1 is connected to the hollow steel column 200 by welding, and the inner wall panel 2 is connected to the hollow steel column 200 and the fishtail steel plate 400 by welding.

[0124] In some embodiments, the building also includes strong and weak current pipes and water pipes. The pipelines such as strong and weak current pipes and water pipes are arranged vertically at the joints of the assembled wall structure 100, and the horizontal pipelines are arranged along the crests or troughs of the sandwich corrugated steel plate 3, and circular holes are opened at the joints of the upper and lower layers of the inner wall panel 2, which are used as internal pipeline inspection holes.

[0125] In a specific embodiment, the assembly sequence of the assembled wall structure 100 from the inside to the outside is: first, the inner wall panel 2 is placed on the fishtail steel plate 400 for welding, then the I-shaped steel rib 7 and the L-shaped rib 601 are welded, and the connecting steel plate 602 is connected to the two L-shaped ribs 601 with bolts, such as Figure 3As shown, the fixed support 402 of the corrugated steel plate fixing device 4 is connected to the inner wall panel 2 by bolts, and the two butt-jointed low-yield point sandwich corrugated steel plates 3 are initially fixed on the special-shaped fixed end head 401 with the fixed support 402, and then the adjusting nut 4 is welded to the corresponding positions inside and outside the outer wall panel 1, and the special-shaped fixed end head 401 with the bolt connecting rod 403 is passed through the adjusting nut 4, and then the outer wall panel 1 is welded at the corresponding position, and the bolt connecting rod 403 is rotated to make the two special-shaped fixed end heads 401 clamp the two sandwich corrugated steel plates 3.

[0126] The present invention also provides a construction method for the above-mentioned assembled explosion-proof building, comprising the following steps:

[0127] S10: The hollow steel column 200 and the hollow square steel beam 300 are symmetrically arranged according to the building requirements, and fishtail steel plates 400 are welded inside the hollow steel column 200 and the hollow square steel beam 300 respectively;

[0128] S20: Weld the inner wall panel 2 to the fishtail steel plate 400, arrange strong and weak current pipes and water pipes at appropriate positions as needed, and install a second weld reinforcement device 6 at the weld positions of the two second stiffening steel plates 201;

[0129] S30: The fixing support 402 of the corrugated steel plate fixing device 4 is connected to the inner wall panel 2 by bolts, the two butted sandwich corrugated steel plates 3 are initially fixed by the special-shaped fixing end 401 with the fixing support 402, and the energy absorbing and shock absorbing material is filled in the energy dissipation cavity 301 of the two sandwich corrugated steel plates 3;

[0130] S40: L-shaped steel members 501 are symmetrically welded on both sides of the weld seams of the two first stiffening steel plates 101 of the outer wall panel 1, a shear groove 9 is welded on the top of the outer wall panel 1, a shear key 8 is welded on the bottom of the outer wall panel 1, an adjusting nut 404 is welded on the outer wall panel 1, and then a special-shaped fixing end 401 with a bolt connecting rod 403 is passed through the adjusting nut 4, and then the outer wall panel 1 is connected to the hollow steel column 200 by welding, and the two sandwich corrugated plates 3 are clamped by rotating the bolt connecting rod 403, and then the steel sleeve 502 is sleeved on the L-shaped steel member 501 through the vertical steel bar 503;

[0131] In this step, a new method for reinforcing wall welds is provided, which is easy to install and replace, and cooperates with the segmented wall (two first stiffening steel plates) to improve the integrity and bearing capacity of the segmented wall. In addition, this type of weld reinforcement device can also be used to reinforce wall cracks of different shapes.

[0132] S50: welding is performed at the intersection of the assembled wall structure 100, the hollow steel column 200, and the hollow square steel beam 300, and then welding a steel floor slab;

[0133] S60: inserting the shear key 8 at the bottom of the outer wall panel 1 of the second-layer wall frame 100a into the shear groove 9 at the top of the outer wall panel 1 of the first-layer wall frame 100a, and welding the first-layer wall frame 100a and the second-layer wall frame 100a at their intersection;

[0134] S70: Repeat steps S20, S30, S40, S50, and S60 to lay the top plate to form an overall assembled explosion-proof building.

[0135] In this step, since the outer wall panel is divided into blocks, the connection between the sandwich corrugated plate and the inner wall panel can be temporarily fixed by manual operation before the outer wall panel is completely installed. For example, the sandwich corrugated steel plate is temporarily fixed by manual operation, and then half of the outer wall panel (i.e., a first stiffening steel plate) is installed, and the sandwich corrugated steel plate is fixed by the special-shaped fixing end of the outer wall panel. At this time, the temporary fixation by manual operation can be removed, and finally the other half of the outer wall steel plate (i.e., another first stiffening steel plate) is installed, the special-shaped fixing end is tightened, and a weld is added at the connection between the two first stiffening steel plates.
