Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated buildings, and in particular relates to an integral explosion-proof prefabricated frame structure factory building. Background Art

[0002] In recent years, explosion accidents have occurred frequently at home and abroad, posing a huge threat to people's lives, health and property safety. There are many reasons for explosion accidents. Among industrial explosion accidents, dust explosions and chemical raw material explosions are the most common causes of accidents, and are usually the types of explosion accidents that cause the most casualties and property losses. In view of the serious destructiveness of industrial explosion accidents, how to enhance the explosion-proof performance of structures under explosion loads and minimize the loss of people's lives and property has become a top priority in industrial building research. Explosion impact loads have many characteristics such as short duration, strong load, easy to break out, difficult to warn, and large damage, which leads to the dynamic behavior of explosion relief structures when they are subjected to explosion loads. It is very complex. At present, under the action of explosion impact loads, there are two main methods to improve the safety performance of structures: explosion resistance and explosion relief. The most widely used and effective explosion-proof means is explosion relief design.

[0003] There are various types of industrial plant structures. According to the type of engineering materials, they can be divided into brick-concrete structure, reinforced concrete structure, steel structure and other plant structures; according to different systems, they can be divided into rigid frame structure, bent frame structure, arch structure, etc.; the roof truss of the plant can also be divided into reinforced concrete roof truss, steel roof truss, wooden roof truss and other forms. When an explosion occurs, the energy is mostly released through the explosion vents on the structure. The explosion venting capacity is limited, and it is easy to produce building debris during the explosion venting process, causing secondary damage. In addition, most buildings after the explosion cannot be reused and can only be demolished and rebuilt, exacerbating the loss of economic property. Therefore, it is necessary to establish a universal and diverse explosion venting structure to meet the actual needs of explosion venting protection for industrial plant structures. Summary of the invention

[0004] The purpose of the present invention is to provide an integral explosion-proof assembled frame structure factory building to solve the problem that the existing factory building is severely damaged when subjected to explosion. The technical solution adopted by the present invention is as follows:

[0005] An integral explosion-proof assembled frame structure factory building, comprising a plurality of connectors, a plurality of supporting devices, four sets of explosion-proof wall components, four corner columns, frame beams and a roof plate;

[0006] The support device includes an independent foundation, a stopper and a sliding base, the stopper is connected to a plurality of pre-buried anchor bars cast in the independent foundation, a plurality of mutually parallel slide grooves are provided on the upper end surface of the stopper, a plurality of convex strips are provided on the lower end surface of the sliding base, and the plurality of convex strips are slidably matched with the plurality of slide grooves in a one-to-one correspondence;

[0007] Define four of several support devices as corner supports, and define the remaining support devices as side supports. Divide the several side supports into four groups. The four corner supports are correspondingly arranged at the four corners of the rectangular planning edge of the factory building. The four groups of side supports are correspondingly arranged along the four side lines of the rectangular planning edge of the factory building. The several chutes of the upper limiters on the side supports are arranged perpendicular to the side lines of the corresponding rectangular planning edge. The included angle between the several chutes of the upper limiters on the corner supports and the several chutes on the adjacent side supports is 45°. The four corner columns are correspondingly arranged on the four sliding bases;

[0008] The explosion venting wall assembly includes several upright columns arranged at intervals. The tops of the several upright columns are respectively connected to the wall clamps, and the bottoms of the several upright columns are respectively connected to another wall clamp. The wall clamps are arranged horizontally. The upper and lower sides of the wall surface assembly slide along the longitudinal directions of the two wall clamps respectively. The wall surface assembly is formed by splicing several sequentially arranged wall surface units;

[0009] The four groups of explosion venting wall assemblies correspond to the four groups of side supports one by one. The several upright columns are correspondingly arranged on the sliding bases of the several side supports. The horizontal two sides of the wall surface assembly are respectively connected to the corresponding corner columns on both sides. The four wall surface assemblies enclose to form the rectangular wall of the factory building. An access door can be opened on any wall surface unit as needed;

[0010] The frame beam is composed of several horizontally arranged horizontal beams and several vertically arranged horizontal beams intersecting with each other. The two ends of the horizontally arranged horizontal beams protrude from the horizontal beams arranged horizontally on both sides, and the two ends of the vertically arranged horizontal beams protrude from the horizontal beams arranged vertically on both sides, so that several beam ends are formed around the frame beam. The frame beam is located between several upright columns. The several beam ends correspond to the tops of the several upright columns one by one. The roof slab is laid on the frame beam;

[0011] The connector includes a piston rod part and two sleeve parts. The two ends of the piston rod part are respectively sleeved and slidably matched with the two sleeve parts;

[0012] Two decomposition ends are formed between the beam end and the corresponding upright column, and two decomposition ends are formed between adjacent two wall surface units. Several connectors are arranged between any two decomposition ends. The connectors are arranged horizontally. The two sleeve parts of the connector are respectively connected to the two decomposition ends that are matched with each other. Before the explosion venting, the adjacent two wall surface units are in contact with each other, the upright column is in contact with the corresponding beam end, and the two sleeve parts of all connectors are in contact with each other. When an explosion occurs, the four wall surface assemblies are impacted by the explosion, and drive several upright columns and the four corner columns to slide in the direction away from the interior of the factory building at the same time. The four corner columns pull the corresponding eight wall surface units at the same time, so that the two sleeve parts of the corresponding connectors are separated, and explosion venting openings are formed by the separation between the two decomposition ends that are matched by the connectors.

[0013] Further, two upper and lower first inter-column connecting beams are provided between adjacent two columns. The upper wall fixture is connected to the upper first inter-column connecting beam, and the lower wall fixture is connected to the lower first inter-column connecting beam.

[0014] Further, two second inter-column connecting beams are provided between the corner column and the adjacent column, one above the other. The second inter-column connecting beam is fixedly connected to the corresponding column. A plurality of connectors are provided between the second inter-column connecting beam and the corresponding corner column. The two sleeve parts of the connector are respectively connected to the corresponding corner column and the second inter-column connecting beam in a matching manner, so that the corner column abuts against or moves away from the corresponding second inter-column connecting beam.

[0015] Further, a bracket structure protruding toward the inner side of the workshop is provided at the top end of the column. The beam end of the frame beam slides on the upper end surface of the bracket structure of the corresponding column.

[0016] Further, the upper wall fixture is located below the bracket structure. A first supplementary beam block is provided between adjacent two columns. The first supplementary beam block is located on the upper wall fixture. The upper end surface of the first supplementary beam block is flush with the upper end surface of the column. A second supplementary beam block is provided between the corner column and the adjacent column. The second supplementary beam block is connected to the corresponding column. The corner column abuts against or moves away from the second supplementary beam block. The upper end surfaces of the second supplementary beam block, the column and the corner column are flush.

[0017] Further, the wall fixture is L-shaped. The wall fixture includes a horizontal portion and a vertical portion. The horizontal portion of the upper wall fixture is connected to the upper end surfaces of the corresponding plurality of first inter-column connecting beams. A chute is formed between the vertical portion of the upper wall fixture and the corresponding plurality of first inter-column connecting beams. The horizontal portion of the lower wall fixture is connected to the lower end surfaces of the corresponding plurality of first inter-column connecting beams. A chute is formed between the vertical portion of the lower wall fixture and the corresponding plurality of first inter-column connecting beams. The upper and lower sides of the wall component are respectively slidably engaged with the corresponding chutes.

[0018] Further, a safety rod is provided on the stopper. The safety rod vertically penetrates through a plurality of the chutes. Before explosion, the sliding base is located at the end of the stopper close to the inner side of the workshop. The outer periphery of the safety rod blocks the end of the plurality of convex strips away from the inner side of the workshop. When an explosion occurs, the explosion shock drives the sliding base to cut and damage the safety rod, so that the sliding base slides toward the end of the stopper away from the inner side of the workshop.

[0019] Further, the shear resistance bearing capacity of the safety rod satisfies the following formula:

[0020]

[0021] where: n v is the number of the chutes;

[0022] d is the radius of the safety rod;

[0023] is the design value of the shear strength of the bumper.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. When an explosion occurs in the invented factory building, the four wall components displace to form a number of explosion relief openings, thereby playing the role of releasing energy. Releasing the explosion energy through the explosion relief openings can effectively reduce the damage caused by the explosion to the factory building and can also greatly reduce the impact on the personnel inside the factory building.

[0026] 2. Since the invented factory building can release the explosion energy when an explosion occurs and reduce the damage caused by the explosion to the factory building, the repair work on the factory building after the explosion is less, the repair cost is low, and it is easy to continue using after repair.

However, it should be understood that these descriptions are only exemplary and do not intend to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

The fixed connections, namely non-detachable connections, include but are not limited to conventional fixed connection methods such as hemming connection, rivet connection, bonding connection, and welding connection. The detachable connections include but are not limited to conventional disassembly methods such as bolt connection, snap connection, pin connection, and hinge connection. When the specific connection method is not clearly defined, it is defaulted that at least one connection method can be found among the existing connection methods to achieve this function, and those skilled in the art can choose according to their needs. For example: welding connection is selected for fixed connection, and bolt connection is selected for detachable connection.

[0049] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are explanations of the present invention, and the present invention is not limited to the following embodiments.

[0050] Embodiment: As Figures 1 to 19 shown, an integrally explosion-relieved prefabricated frame structure factory building includes a number of connectors 6, a number of support devices 1, four groups of explosion-relieved wall assemblies 2, four corner columns 3, frame beams 5, and roof panels 4;

[0051] The support device 1 includes an independent foundation 11, a limiter 12, and a sliding base 14. The limiter 12 is connected to a number of embedded anchor bars poured in the independent foundation 11. A number of mutually parallel chutes are provided on the upper end surface of the limiter 12. A number of protrusions are provided on the lower end surface of the sliding base 14, and the number of the protrusions is in one-to-one sliding fit with the number of the chutes;

[0052] Four of the number of support devices 1 are defined as corner supports, and the remaining support devices 1 are defined as side supports. The number of the side supports is divided into four groups. The four corner supports are arranged at the four corners of the rectangular plan edge of the factory building in one-to-one correspondence. The four groups of side supports are arranged along the four side lines of the rectangular plan edge of the factory building in one-to-one correspondence. The number of chutes of the limiter 12 on the side supports is arranged perpendicular to the side lines of the corresponding rectangular plan edge. The included angle between the number of chutes of the limiter 12 on the corner supports and the number of chutes on the adjacent side supports is 45°. The four corner columns 3 are arranged on the four sliding bases 14 in one-to-one correspondence;

[0053] The explosion-relieved wall assembly 2 includes a number of upright columns 23 arranged at intervals. The tops of the number of upright columns 23 are respectively connected to wall clamps 22, and the bottoms of the number of upright columns 23 are respectively connected to another wall clamp 22. The wall clamps 22 are arranged horizontally. The upper and lower sides of the wall surface assembly slide along the long directions of the two wall clamps 22 respectively. The wall surface assembly is composed of a number of wall surface units 21 arranged in sequence;

[0054] Four groups of explosion relief wall assemblies 2 correspond to the four groups of the side supports one by one. A number of columns 23 are arranged on the sliding bases 14 of the corresponding side supports one by one. The two horizontal sides of the wall assembly are respectively connected to the corresponding corner columns 3 on both sides. The four wall assemblies enclose to form a rectangular wall of the workshop. An access door can be opened on any wall unit 21 as required.

[0055] The frame beam 5 is composed of a number of horizontally arranged horizontal beams and a number of vertically arranged horizontal beams intersecting with each other. The two ends of the horizontally arranged horizontal beams protrude from the horizontally arranged horizontal beams on both sides. The two ends of the vertically arranged horizontal beams protrude from the vertically arranged horizontal beams on both sides, so that a number of beam ends are formed around the frame beam 5. The frame beam 5 is located between a number of columns 23. A number of the beam ends correspond to the tops of a number of columns 23 one by one. The roof slab 4 is laid on the frame beam 5.

[0056] The connector 6 includes a piston rod part 62 and two sleeve parts 61. The two ends of the piston rod part 62 are respectively sleeved and slidably matched with the two sleeve parts 61.

[0057] Two decomposition ends are formed between the beam end and the corresponding column 23. Two decomposition ends are formed between adjacent two wall units 21. A number of connectors 6 are arranged between any two of the decomposition ends. The connectors 6 are arranged horizontally. The two sleeve parts 61 of the connector 6 are respectively connected to the two decomposition ends that are matched with each other. Before the explosion relief, adjacent two wall units 21 are in contact with each other, the column 23 is in contact with the corresponding beam end, and the two sleeve parts 61 of all the connectors 6 are in contact with each other. When an explosion occurs, the four wall assemblies are impacted by the explosion and drive a number of columns 23 and the four corner columns 3 to slide in the direction away from the interior of the workshop at the same time. The four corner columns 3 pull the corresponding eight wall units 21 at the same time, so that the two sleeve parts 61 of the corresponding connectors 6 are separated, and explosion relief openings are formed by the separation between the two decomposition ends that are matched by the connectors 6.

[0058] The main function of the support device 1 is to provide support for the overall workshop structure and provide a platform for the overall sliding of the main structure during an explosion, as Figure 2 shown. Among them: The independent foundation 11 is a cast-in-site concrete foundation, which provides support for the overall workshop. Its area should meet the relevant requirements. After the independent foundation 11 is poured, a limiter 12 with a T-shaped chute is installed on it. The limiter 12 is a thick steel plate member and is connected to the independent foundation 11 through anchor bolts.

[0059] The number of the support device 1, the column 23 and the wall unit 21 is set as required. The main functions of the connector 6 are as follows: a. Connecting the two disassembly ends to improve the overall stability of the structure; b. Adopting the form that the piston rod part 62 is slidably matched with the two sleeve parts 61 respectively. After the piston rod part 62 and the sleeve part 61 are combined successfully, structural glue is injected into the sleeve part 61, which can absorb part of the energy when an explosion occurs, thereby reducing the pressure caused by the explosion load on the structure and the internal personnel, reducing or avoiding structural damage and casualties. When the explosion impact force reaches the threshold value, relative sliding occurs between the matching sleeve part 61 and the piston rod part 62, and the connector 6 is stretched, and the disassembly ends are separated from each other to form a blast vent, thereby releasing energy. The structure of the connector 6 is shown in Figure 9 A limiting structure is added between the piston rod part 62 and the sleeve part 61, so that the piston rod part 62 and the sleeve part 61 are always connected and do not separate. When the corner column 3 pulls the corresponding wall unit 21, the wall unit 21 at the end can transfer the pulling force through the connector 6, so that the other wall units 21 are separated in turn.

[0060] When an explosion occurs in the factory building of the present invention, the four wall assemblies are displaced, and a number of blast vents can be formed, so as to play the role of releasing energy. Figure 13 The design explosion cloud diagram of a general factory building is given. Figure 14 The impact stress diagram of the rectangular wall of a general factory building when an explosion occurs is given. Figure 15 The design explosion cloud diagram of the factory building of the present invention is given. Figure 16 The impact stress diagram of the rectangular wall of the factory building of the present invention when an explosion occurs is given. Figure 17 The comparison diagram of the change curves of the impact pressure received by the center of the wall during the explosion of a general factory building and the factory building of the present invention is given. Based on ABAQUS, the blast venting ability of the overall blast venting factory building is verified, and 1 / 4 of the structure is selected for simulation. Since the final structure of the explosion simulation is greatly affected by the size of the structure, the material properties of the components, etc., general numerical values cannot be given. Therefore, this embodiment aims to verify the difference between the overall blast venting design and the general design. Through Figures 13 to 17 It can be seen that the maximum stress values during the explosion of the factory building of the present invention and the general factory building are relatively close. The explosion impact pressure borne by the wall unit 21 of the present invention reaches the peak value of 400 MPa before the blast vent is generated by decomposition, but this peak value is much smaller than the explosion impact pressure of 700 MPa borne by the general factory building during the explosion. Releasing the explosion energy through the blast vent can effectively reduce the damage caused by the explosion to the factory building and can also greatly reduce the impact of the explosion on the personnel in the factory building.

[0061] Two adjacent columns 23 are connected by two first inter-column connecting beams 24 arranged above and below, the upper wall fixture 22 is connected to the upper first inter-column connecting beam 24, and the lower wall fixture 22 is connected to the lower first inter-column connecting beam 24. Providing two first inter-column connecting beams 24 between two adjacent columns 23 can effectively improve the connection strength between the two columns 23, and connecting the wall fixture 22 to the corresponding first inter-column connecting beams 24 can ensure the reliable fixation of the wall fixture 22.

[0062] Two second inter-column connecting beams 28 are arranged above and below between the corner column 3 and the adjacent column 23. The second inter-column connecting beams 28 are fixedly connected to the corresponding column 23. A plurality of connectors 6 are arranged between the second inter-column connecting beams 28 and the corresponding corner column 3. Two sleeve portions 61 of the connector 6 are respectively connected to the matching corner column 3 and the second inter-column connecting beams 28, so that the corner column 3 and the corresponding second inter-column connecting beams 28 are abutted against or away from each other. The two second inter-column connecting beams 28 are arranged between the corner column 3 and the adjacent column 23, which can effectively improve the connection strength between the corner column 3 and the adjacent column 23.

[0063] The top of the column 23 is provided with a corbel structure 26 protruding toward the inside of the plant, and the beam end of the frame beam 5 slides on the upper end surface of the corbel structure 26 of the corresponding column 23. The corbel structure 26 supports the corresponding beam end, so that when an explosion occurs, the column 23 can slide in a direction away from the inside of the plant, and still support the corresponding beam end, thereby improving the stability of the plant structure.

[0064] The upper wall clamp 22 is located below the corbel structure 26, and two adjacent columns 23 are connected by a first filling beam block 25. The first filling beam block 25 is located on the upper wall clamp 22, and the upper end surface of the first filling beam block 25 is flush with the upper end surface of the column 23. A second filling beam block 27 is provided between the corner column 3 and the adjacent column 23, and the second filling beam block 27 is connected to the corresponding column 23. The corner column 3 is abutted against or away from the second filling beam block 27, and the upper end surface of the second filling beam block 27, the upper end surface of the column 23 and the upper end surface of the corner column 3 are flush. In order to ensure the smooth sliding of the wall assembly and enable the wall unit 21 to smoothly form an explosion vent when an explosion occurs, it is necessary to ensure that the corbel structure 26 does not block the wall assembly. Therefore, the upper wall clamp 22 needs to be arranged below the corbel structure 26. Therefore, a gap will be formed on the upper side between two adjacent columns 23, and the gap will be filled by the first gap-filling beam block 25.

[0065] The wall fixture 22 is L-shaped. The wall fixture 22 includes a horizontal part and a vertical part. The horizontal part of the upper wall fixture 22 is connected to the upper end faces of a corresponding number of first column-to-column connecting beams 24. A chute is formed between the vertical part of the upper wall fixture 22 and a corresponding number of first column-to-column connecting beams 24. The horizontal part of the lower wall fixture 22 is connected to the lower end faces of a corresponding number of first column-to-column connecting beams 24. A chute is formed between the vertical part of the lower wall fixture 22 and a corresponding number of first column-to-column connecting beams 24. The upper and lower sides of the wall surface assembly are respectively in sliding fit with the corresponding chutes. To improve the reliable connection of the wall fixture 22, the horizontal part of the wall fixture 22 can be fixed to the end face of the corresponding first column-to-column connecting beam 24. A number of notches can be opened on the horizontal part of the wall fixture 22 to avoid the corresponding columns 23. Or, according to needs, the wall fixture 22 can be pre-cast on the columns 23 in advance. The chute is set according to the thickness of the wall surface unit.

[0066] The limiter 12 is provided with a safety rod 13. The safety rod 13 vertically penetrates through a number of the chutes. Before explosion relief, the sliding base 14 is located at the end of the limiter 12 close to the interior of the factory building. The outer periphery of the safety rod 13 blocks the end away from the interior of the factory building of a number of the convex strips. When an explosion occurs, the explosion shock drives the sliding base 14 to cut and damage the safety rod 13, causing the sliding base 14 to slide towards the end of the limiter 12 away from the interior of the factory building. The safety rod 13 is used to ensure that the sliding base 14 does not slide before explosion relief, improving the structural stability of the factory building. The safety rod 13 is a damaged component. When an explosion occurs, the wall surface assembly is subjected to the explosion impact force, causing the sliding base 14 and the corresponding limiter 12 to cut the safety rod 13, and then the sliding base 14 can slide smoothly.

[0067] The shear resistance bearing capacity of the safety rod 13 Satisfies the following formula:

[0068]

[0069] In the formula: n v Is the number of the chutes;

[0070] d is the radius of the safety rod 13;

[0071] Is the shear strength design value of the safety rod 13.

[0072] The present invention provides a calculation formula for the shear resistance bearing capacity of the safety rod 13. The safety rod 13 designed through formula calculation can ensure that the sliding base 14 is blocked from sliding before explosion relief, and can also ensure that the safety rod 13 can be smoothly cut when an explosion occurs, enabling the sliding base 14 to slide smoothly.

[0073] The test results show that in the design of the overall explosion venting - prefabricated frame structure workshop proposed in this patent, the sliding device can play a role, its control device can be used normally, and when an explosion occurs, the structure can undergo overall sliding, release energy, and complete the explosion venting work.

[0074] Figure 19 The construction, explosion venting and repair processes of the workshop of the present invention are given, and the steps for constructing the workshop are as follows:

[0075] First step, pour a number of independent foundations 11, and arrange limiters 12 and sliding bases 14;

[0076] Second step, install a number of columns 23 and four corner columns 3;

[0077] Third step, install a number of first inter - column connecting beams 24, a number of second inter - column connecting beams 28, install four - sided wall components, install frame beams 5 and roof slabs 4;

[0078] Fourth step, the assembly of the workshop is completed and put into use.

[0079] When an explosion occurs, the explosion venting and repair steps of the workshop are as follows:

[0080] First step, four groups of explosion - venting wall components 2 and four corner columns 3 slide as a whole in the direction away from the interior of the workshop. The corner columns 3 pull the corresponding wall units 21, and explosion venting openings are formed by the separation between the two decomposition ends cooperated by the connectors 6. The impact force of the explosion releases energy through the explosion venting openings;

[0081] Second step, repair the damaged parts of the workshop;

[0082] Third step, determine whether the repaired workshop can continue to be used. If it can continue to be used, then continue to be put into use. If it cannot continue to be used, then abandon its use.

[0083] The workshop of the present invention can form a number of explosion venting openings when an explosion occurs, release the energy generated by the explosion, reduce the damage caused by the explosion to the workshop. Therefore, the repair work for the workshop after withstanding an explosion is less, the repair cost is low, and it is easy to continue to be used after repair.

[0084] The present invention proposes an explosion venting structure form for industrial workshop structures. This structure adopts the prefabricated design concept and can achieve the following functions:

[0085] 1. Each component can be assembled, and different industrial buildings can be established by adjusting the types of components, improving the application scope and flexibility of the explosion venting structure. Moreover, the components can be pre - fabricated in the factory and assembled on - site, which is green and environmentally friendly and has higher construction efficiency;

[0086] 2. The walls and some joints are connected by connectors 6, endowing the structure with the overall explosion venting ability and enhancing the explosion - proof performance of the structure under explosion loads;

[0087] 3. When an explosion occurs in the factory building, the response speed is fast. Under overall explosion venting, no large-sized building debris will be generated, significantly reducing secondary injuries.

[0088] 4. The columns 23 and corner columns 3 are both installed on the sliding device 1 and can be reused after repair after an explosion, greatly reducing property losses.

[0089] The above embodiments are only illustrative descriptions of the present invention and do not limit its protection scope. Those skilled in the art can also make partial changes to it. As long as they do not exceed the spiritual essence of the present invention, they are within the protection scope of the present invention.
