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:

[0011] The connector comprises a piston rod portion and two sleeve portions, and the two ends of the piston rod portion are respectively sleeved and slidably matched with the two sleeve portions;

[0012] Two decomposition ends are formed between the ends of the beams and the corresponding columns, and two decomposition ends are formed between two adjacent wall units. Several connectors are provided between any two of the decomposition ends, and the connectors are arranged horizontally. The two sleeve parts of the connectors are respectively connected to the two matching decomposition ends. Before explosion relief, the two adjacent wall units are abutted against each other, the columns are abutted against the corresponding ends of the beams, and the two sleeve parts of all connectors are abutted against each other. When an explosion occurs, the four wall components are impacted by the explosion, and drive several columns and four corner columns to slide in a direction away from the interior of the factory building at the same time.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0048] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection is a non-detachable connection including but not limited to conventional fixed connection methods such as folding connection, rivet connection, bonding connection and welding connection. The detachable connection includes but not limited to conventional detachable methods such as bolt connection, snap connection, pin connection and hinge connection.

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 in conjunction with the accompanying drawings. The following embodiments are provided to explain the present invention, but the present invention is not limited to the following embodiments.

[0050] Example: Figures 1 to 19 As shown, an integral explosion-proof assembled frame structure factory building includes a plurality of connectors 6, a plurality of supporting devices 1, four explosion-proof wall components 2, four corner columns 3, frame beams 5 and a roof plate 4;

[0051] The support device 1 includes an independent foundation 11, a stopper 12 and a sliding base 14. The stopper 12 is connected to a plurality of pre-buried anchor bars cast in the independent foundation 11. A plurality of mutually parallel slide grooves are provided on the upper end surface of the stopper 12. A plurality of convex strips are provided on the lower end surface of the sliding base 14. The plurality of convex strips are slidably matched with the plurality of slide grooves in a one-to-one correspondence.

[0052] Four of the plurality of support devices 1 are defined as corner supports, and the remaining support devices 1 are defined as side supports. The plurality of side supports are divided into four groups, and the four corner supports are arranged one by one at the four corners of the rectangular planning edge of the plant building, and the four groups of side supports are arranged one by one along the four sides of the rectangular planning edge of the plant building, and the plurality of slide grooves of the upper limit stopper 12 of the side support are arranged perpendicular to the sides of the rectangular planning edge, and the angle between the plurality of slide grooves of the upper limit stopper 12 of the corner support and the plurality of slide grooves on the adjacent side support is 45°, and the four corner columns 3 are arranged one by one on the four sliding bases 14;

[0053] The explosion relief wall assembly 2 includes a plurality of columns 23 arranged at intervals, the tops of the plurality of columns 23 are respectively connected to the wall fixtures 22, the bottoms of the plurality of columns 23 are respectively connected to another wall fixture 22, the wall fixtures 22 are arranged horizontally, the upper and lower sides of the wall assembly slide along the length direction of the two wall fixtures 22 respectively, and the wall assembly is composed of a plurality of wall units 21 arranged in sequence;

[0054] The four groups of explosion relief wall components 2 correspond to the four groups of side supports one by one, and a plurality of columns 23 are arranged on the sliding bases 14 of the plurality of side supports one by one. The horizontal sides of the wall components are respectively connected to the corresponding corner columns 3 on both sides. The four wall components are surrounded to form a rectangular wall of the factory building, and an entrance and exit door can be opened on any wall unit 21 as needed;

[0055] The frame beam 5 is composed of a plurality of horizontal beams arranged transversely and a plurality of horizontal beams arranged longitudinally, and both ends of the longitudinally arranged horizontal beams protrude from the horizontal beams arranged transversely on both sides, and both ends of the transversely arranged horizontal beams protrude from the horizontal beams arranged longitudinally on both sides, so that a plurality of beam ends are formed around the frame beam 5. The frame beam 5 is located between a plurality of columns 23, and the plurality of beam ends correspond to the top ends of the plurality of columns 23 one by one. A roof board 4 is laid on the frame beam 5;

[0056] The connector 6 includes a piston rod portion 62 and two sleeve portions 61, and the two ends of the piston rod portion 62 are respectively sleeved and slidably matched with the two sleeve portions 61;

[0057] Two decomposition ends are formed between the ends of the beams and the corresponding columns 23, and two decomposition ends are formed between two adjacent wall units 21. A number of connectors 6 are provided between any two of the decomposition ends. The connectors 6 are arranged horizontally, and the two sleeve parts 61 of the connectors 6 are respectively connected to the two matching decomposition ends. Before explosion relief, the two adjacent wall units 21 are abutted against each other, the columns 23 are abutted against the corresponding ends of the beams, and the two sleeve parts 61 of all connectors 6 are abutted against each other. When an explosion occurs, the four wall components are impacted by the explosion, and drive a number of columns 23 and four corner columns 3 to slide in a direction away from the interior of the factory building at the same time. The four corner columns 3 simultaneously pull the corresponding eight wall units 21 to separate the two sleeve parts 61 of the corresponding connectors 6, and the two decomposition ends matched by the connectors 6 are separated to form an explosion relief port.

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

[0059] The number of the supporting device 1, the column 23 and the wall unit 21 is set according to the needs. The functions of the connector 6 are mainly: a. connecting the two decomposition ends to improve the overall stability of the structure; b. adopting the form of sliding cooperation between the piston rod part 62 and the two sleeve parts 61 respectively. After the piston rod part 62 and the sleeve part 61 are successfully combined, the structural glue is injected into the sleeve part 61, which can absorb part of the energy when the 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, the matching sleeve part 61 and the piston rod part 62 slide relative to each other, the connector 6 is elongated, and the decomposition ends are separated to form an explosion vent, thereby releasing energy. The structure of the connector 6 is shown in FIG. Fig. 9 A limiting structure is added between the piston rod portion 62 and the sleeve portion 61, so that the piston rod portion 62 and the sleeve portion 61 always remain connected and do not separate. When the corner column 3 pulls the corresponding wall unit 21, the wall unit 21 at the end can transmit the pulling force through the connector 6, so that the other wall units 21 are separated in sequence.

[0060] When an explosion occurs in the factory building of the present invention, the four wall components are displaced to form a plurality of explosion vents, thereby releasing energy. Fig.13 The design explosion cloud diagram of ordinary factory buildings is given. Fig.14 The impact stress diagram of the rectangular wall when an ordinary factory building explodes is given. Fig.15 The design explosion cloud diagram of the plant building of the present invention is given. Fig.16 The impact stress diagram of the rectangular wall when the factory building of the present invention explodes is given. Fig.17 A comparison chart of the impact pressure at the center of the wall of an ordinary factory building and the factory building of the present invention when an explosion occurs is given. The explosion-proof capability of the overall explosion-proof factory building is verified based on ABAQUS, and a 1 / 4 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., it is impossible to give a general numerical value. Therefore, this embodiment aims to verify the difference between the overall explosion-proof design and the ordinary design. Figure 13 to Figure 17 It can be seen that the maximum stress values ​​of the factory building of the present invention and the ordinary factory building during an explosion are relatively close. The explosion shock pressure borne by the wall unit 21 of the present invention before decomposing to produce the explosion vent reaches a peak value of 400MPa, but this peak value is much smaller than the explosion shock pressure of 700MPa borne by the ordinary factory building during an explosion. Releasing the explosion energy through the explosion vent can effectively reduce the damage to the factory building caused by the explosion, 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. The second filling beam block 27 is connected to the corresponding column 23, and the corner column 3 is abutted against or away from the second filling beam block 27. 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 clamp 22 is L-shaped, and includes a horizontal portion and a vertical portion. The horizontal portion of the wall clamp 22 located on the upper side is connected to the upper end surface of the corresponding first inter-column connecting beams 24, and a slide groove is formed between the vertical portion of the upper wall clamp 22 and the corresponding first inter-column connecting beams 24. The horizontal portion of the wall clamp 22 located on the lower side is connected to the lower end surface of the corresponding first inter-column connecting beams 24, and a slide groove is formed between the vertical portion of the lower wall clamp 22 and the corresponding first inter-column connecting beams 24. The upper and lower sides of the wall assembly are respectively slidably matched with the corresponding slide grooves. In order to improve the reliable connection of the wall clamp 22, the horizontal portion of the wall clamp 22 is fixed to the end surface of the corresponding first inter-column connecting beam 24, and a plurality of notches can be opened on the horizontal portion of the wall clamp 22 to avoid the corresponding columns 23. The wall clamp 22 can also be cast on the columns 23 in advance as needed, and the slide groove is set according to the thickness of the wall unit.

[0066] The limiter 12 is provided with a safety rod 13, which vertically penetrates the plurality of slide grooves. Before explosion relief, the sliding base 14 is located at the end of the limiter 12 close to the interior of the plant, and the outer periphery of the safety rod 13 blocks the end of the plurality of convex strips away from the interior of the plant. When an explosion occurs, the explosion impact drives the sliding base 14 to cut off the damaged safety rod 13, so that the sliding base 14 slides toward the end of the limiter 12 away from the interior of the plant. The safety rod 13 is used to ensure that the sliding base 14 does not slide before explosion relief, thereby improving the structural stability of the plant. The safety rod 13 is a destructible component. When an explosion occurs, the wall assembly is subjected to the impact of the explosion, so that the sliding base 14 and the corresponding limiter 12 cut off the safety rod 13, and then the sliding base 14 can slide smoothly.

[0067] Shear resistance of the bumper 13 Satisfy the following formula:

[0068]

[0069] Where: n v is the number of the chutes;

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

[0071] It is the design value of the shear strength of the bumper 13.

[0072] The present invention provides a calculation formula for the shear bearing capacity of the safety rod 13. The safety rod 13 designed and calculated by the formula can ensure that the sliding base 14 is prevented from sliding before explosion relief, and can also ensure that the safety rod 13 can be sheared smoothly when an explosion occurs, so that the sliding base 14 can slide smoothly.

[0073] The test results show that in the overall explosion relief-assembled frame structure factory building design 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 slide as a whole to release energy and complete the explosion relief work.

[0074] Fig.19 The construction, explosion relief and repair process of the factory building of the present invention is given, and the steps of building the factory building are as follows:

[0075] The first step is to cast a number of independent foundations 11, arrange the limiters 12 and the sliding base 14;

[0076] The second step is to install several columns 23 and four corner columns 3;

[0077] The third step is to install a plurality of first inter-column connecting beams 24, a plurality of second inter-column connecting beams 28, four wall components, frame beams 5 and roof panels 4;

[0078] The fourth step is to complete the assembly of the factory building and put it into use.

[0079] When an explosion occurs, the steps for venting and repairing the plant are as follows:

[0080] In the first step, the four explosion relief wall components 2 and the four corner columns 3 are slid as a whole in a direction away from the interior of the factory building, and the corner columns 3 pull the corresponding wall units 21, and the two decomposition ends matched by the connector 6 are separated to form an explosion relief port, and the impact force of the explosion releases energy through the explosion relief port;

[0081] The second step is to repair the broken parts of the factory building;

[0082] The third step is to determine whether the repaired factory building can continue to be used. If it can continue to be used, it will continue to be put into use. If it cannot continue to be used, it will be abandoned.

[0083] The factory building of the present invention can form a number of explosion vents when an explosion occurs, release the energy generated by the explosion, and reduce the damage to the factory building caused by the explosion. Therefore, the repair work for the factory building after the explosion is less, the repair cost is low, and it is easy to continue to use after repair.

[0084] The present invention proposes an explosion relief structure for industrial plant structures. The structure adopts an assembled design concept and can achieve the following functions:

[0085] 1. Each component can be assembled, and the types of components can be adjusted to build different industrial buildings, which improves the application scope and flexibility of the explosion-proof structure. The components can be prefabricated in the factory and assembled on site, which is green and environmentally friendly, and has higher construction efficiency;

[0086] 2. The wall and some nodes are connected by connector 6, which gives the structure an overall explosion-proof capability and enhances the explosion-proof performance of the structure under explosion load;

[0087] 3. The factory building responds quickly when an explosion occurs, and the overall explosion relief will not produce large-sized building debris, significantly reducing secondary damage;

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

[0089] The above embodiments are merely exemplary descriptions of the present invention and do not limit its protection scope. Those skilled in the art may also make partial changes thereto, which are within the protection scope of the present invention as long as they do not exceed the spirit of the present invention.
