Description

Technical Field

[0001] The present invention relates to the technical field of building structural structures, and in particular to a safe assembled wall and an assembled building. Background Art

[0002] Prefabricated buildings are constructed by transporting components prefabricated in a workshop to the construction site for on-site assembly. The advantages of this construction method include fast construction, high efficiency, easy standardization, and relatively low impact from external conditions such as climate. Prefabricated walls, the primary structural element of prefabricated buildings, are secured between columns and beams by bolting flanges along the edges of the wall panels to the columns and beams, as well as bolting the flanges between the panels. This creates a rigid connection. Prefabricated walls secured between two columns and beams exhibit high overall rigidity, making them less resilient to natural disasters such as earthquakes and typhoons. These walls are prone to severe deformation and even fracture at the connections between the wall panels and between the wall panels and the columns and beams, leading to significant tilting or collapse. Furthermore, the larger the area of ​​the prefabricated wall between the columns and beams, the less resilient it is to natural disasters such as earthquakes and typhoons. This makes it unsuitable for large buildings, or if the building's walls are large, the density of the columns and beams needs to be increased. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a safe prefabricated wall and prefabricated building. It overcomes the problem of the poor ability of prefabricated walls to resist natural disasters such as earthquakes and typhoons by optimizing the wall panel structure of the prefabricated wall, which helps to make the prefabricated wall have better damping and vibration resistance. In addition, it has a simple design structure, few accessories, and is easy and quick to install.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a safe assembled wall, including a wall panel and at least a pair of side panels.

[0005] The wall panel includes a wall panel body and a plurality of first arm plates and a plurality of connecting columns distributed on at least one pair of opposite side surfaces of the wall panel body, and the two side panels are matched with the two side surfaces respectively. For example, a plurality of first arm plates and a plurality of connecting columns can be respectively arranged on the left side and the right side of the wall panel body, and the two side panels are matched with the left side and the right side of the wall panel body respectively. The first arm plate on each side includes two side arm plates 1 and a plurality of intermediate arm plates 1, and the intermediate arm plates 1 are distributed alternately between the two side arm plates 1. The inner end surface of the side arm plate 1 and the side end surfaces of the intermediate arm plate 1 are formed into V-shaped convex surfaces. The connecting columns are distributed between adjacent side arm plates 1 and intermediate arm plates 1, as well as between two adjacent intermediate arm plates 1. One end of the connecting column is fixedly matched with the wall panel body, and the other end is formed with a stud section, and the stud section is provided with a spring and a matching nut portion.

[0006] The side plate includes a base and a second arm plate, and the second arm plate includes a pair of side arm plates 2 and a plurality of intermediate arm plates 2, with the intermediate arm plates 2 being alternately arranged between the two side arm plates 2. The outer end surfaces of the side arm plates 2 and one end surface of the intermediate arm plates 2 are both formed into V-shaped concave surfaces, that is, the outer end surfaces of the side arm plates 2 and the opposing end surfaces of two adjacent intermediate arm plates 2 are both formed into V-shaped concave surfaces.

[0007] The base body is provided with a plurality of multi-step through-holes extending axially along the length of the second arm plate and corresponding one-to-one with the connecting posts. The stud sections on the connecting posts extend into the multi-step through-holes, allowing the spring and nut to be accommodated within the cavities of the multi-step through-holes, with one end of the spring contacting the bottom surface of the multi-step through-hole and the other end contacting the end surface of the nut.

[0008] The V-shaped concave surfaces on the two side arm plates (II) match the V-shaped convex surfaces on the two side arm plates (I) in a one-to-one correspondence, forming a positive fit. Multiple intermediate arm plates (I) are inserted between adjacent intermediate arm plates (II) with V-shaped concave surfaces on their opposing surfaces, ensuring that the V-shaped convex surfaces on both sides of the intermediate arm plates (I) match the V-shaped concave surfaces on the adjacent two intermediate arm plates (II) in a positive fit. A gap is formed between the outer circumference of the connecting column and the side surface of the second arm plate.

[0009] Optionally, after the first arm plate is matched and connected with the second arm plate, a gap is formed between the end surface of the second arm plate and the side surface of the wall plate body, that is, the length of the first arm plate is greater than the length of the second arm plate.

[0010] Optionally, an elastic portion 1 is formed at the base of the connecting column. The elastic portion 1 can cause the connecting column to elastically deform from its base, thereby causing the column body of the connecting column to elastically deflect relative to its axial extension direction. The elastic portion 1 can be an annular groove with a curved inner bottom surface.

[0011] Optionally, an elastic sleeve is fixedly provided at the inner end of the multi-step through hole, and the stud section passes through the elastic sleeve and then extends into the cavity of the multi-step through hole.

[0012] Optionally, a second elastic portion is formed at the root of at least a portion of the second arm plate, such as only at the root of the second intermediate arm plate and on the side opposite to the side with the V-shaped concave surface. The second elastic portion enables the second arm plate, or in other words, the plate body of the second intermediate arm plate, to elastically deflect from the root along the inner depth direction of the V-shaped concave surface, thereby helping to enhance the connection toughness of the interlocking structure formed between the first arm plate and the second arm plate and improve the deflection resistance.

[0013] Optionally, the second elastic portion is a linear groove portion with a curved inner bottom surface, which is either a single linear groove or a linear groove region formed by a plurality of linear grooves alternately distributed along the length direction of the second intermediate arm plate.

[0014] Optionally, a plurality of elastic ridges are alternately distributed on both inclined surfaces of the V-shaped convex surface or elastic pads are fixedly arranged. After the V-shaped convex surface matches the V-shaped concave surface, the elastic ridges or elastic pads can be sandwiched in the middle.

[0015] Optionally, the elastic convex strip is fixedly embedded in the V-shaped convex surface. The radial cross section of the elastic convex strip is cylindrical or elliptical.

[0016] An assembled building comprises the above-mentioned safe assembled wall.

[0017] The present invention has the following beneficial effects: by optimizing the wall panel structure of prefabricated walls, it helps overcome the problem of prefabricated walls' poor resistance to natural disasters such as earthquakes and typhoons, and helps improve the prefabricated walls' damping and vibration resistance, significantly enhancing their anti-vibration safety performance, hence the name "safe prefabricated wall." Furthermore, the prefabricated wall of the present invention has a simple design structure, requires a limited number of accessories, and is quick and easy to install and disassemble.

They are not used to limit the conditions for implementation of the present invention and therefore have no substantial technical significance.

At the same time, terms such as "upper", "lower", "front", "back", and "middle" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0025] like Figures 1 to 5 The illustrated safety assembled wall comprises a wall panel 10 and a pair of side panels 20, with the two side panels 20 being disposed oppositely on the left and right sides of the wall panel 10. In practice, a pair of side panels 20 may also be disposed on the upper and lower sides of the wall panel 10, so the present invention encompasses embodiments including two pairs of side panels 20.

[0026] The wall panel 10 includes a wall panel body 11 and a plurality of first arm panels 12 and a plurality of connecting columns 13 distributed on a pair of opposing side surfaces of the wall panel body 11 (i.e., the left and right sides of the wall panel body 11 shown in the figure). Two side panels 20 correspond to the two side surfaces of the wall panel body 11 on which the first arm panels 12 and connecting columns 13 are provided. When the side panels 20 are disposed on both the upper and lower sides of the wall panel body 11, it is necessary to dispose a plurality of first arm panels 12 and a plurality of connecting columns 13 on both the upper and lower sides of the wall panel body 11. In this case, a plurality of first arm panels 12 and a plurality of connecting columns 13 are disposed on two pairs of opposing side surfaces of the wall panel body 11. Preferably, the number of the first arm panels 12 and the number of the connecting columns 13 disposed on the two opposing side surfaces are the same.

[0027] The first arm plate 12 provided on each side includes two side arm plates 121 and a plurality of intermediate arm plates 122, with the intermediate arm plates 122 being alternately arranged between the two side arm plates 121. The inner end surfaces of the side arm plates 121 and the side end surfaces of the intermediate arm plates 122 are formed into V-shaped convex surfaces 123. The V-shaped convex surfaces 123 extend along the length direction of the first arm plate 12 and cross the entire width direction of the first arm plate 12. Figure 2 、 Figure 4 shown.

[0028] The connecting column 13 is disposed between two adjacent first arm plates 12, specifically, between adjacent side arm plates 121 and intermediate arm plates 122, and between two adjacent intermediate arm plates 122. One end of the connecting column 13 is fixedly mated with the wall panel body 11. This term "fixed mating" encompasses both a fixed connection and an integrally formed fixed mating relationship with the wall panel body 11. The other end (i.e., the free end) of the connecting column 13 is formed with a stud section 131, which is fitted with a spring 14 and a mating nut 15.

[0029] The side plate 20 includes a base 21 and a second arm plate 22 , and the second arm plate 22 includes a pair of side arm plates 221 and a plurality of middle arm plates 222 , and the middle arm plates 222 are alternately distributed between the two side arm plates 221 .

[0030] The outer end surface of the side arm plate 221 and the opposite end surface between the two adjacent intermediate arm plates 222 are both formed as V-shaped concave surfaces 23. That is, the outer end surface of the side arm plate 221 and the opposite end surfaces of the two adjacent (i.e., partially adjacent) intermediate arm plates 222 are both formed as V-shaped concave surfaces 23. The two V-shaped concave surfaces 23 located on the opposite surfaces of the two adjacent intermediate arm plates 222 can be matched with the two V-shaped convex surfaces 123 on the intermediate arm plate 122 inserted therebetween, forming a contact-type plug-in connection structure. Figure 2 、 Figure 4 、 Figure 5 .

[0031] The base 21 is formed with a plurality of multi-step through-holes 211 extending axially along the length of the second arm plate 22 and corresponding one-to-one with the connecting posts 13. The stud segments 131 on the connecting posts 13 extend into the multi-step through-holes 211, allowing the spring 14 and the nut portion 15 to be accommodated within the multi-step through-holes 211. One end of the spring 14 contacts the inner bottom surface of the multi-step through-hole 211, while the other end contacts the end surface of the nut portion 15. By turning the nut portion 15 to adjust its axial position relative to the stud segments 131, the degree of compression of the spring 14 can be adjusted, thereby adjusting the connecting tension exerted by the spring 14 on the connecting post 13. This ensures that the ends of the side panels 20 and wall panels 10 are tightly pressed together, while maintaining a certain (elastic) play between their opposing surfaces.

[0032] An annular body is formed on the outer end surface of the nut portion 15, and the outer circumference of the annular body is formed into a prismatic surface. The maximum outer diameter of the annular body is smaller than the inner diameter of the outer end of the multi-step through hole 211, so as to facilitate the operation of screwing the nut portion 15. The threaded through hole on the nut portion 15 can be extended to the annular body, or the inner diameter of the annular body can be larger than the inner diameter of the threaded through hole.

[0033] The V-shaped concave surfaces 23 on the two side arm plates 221 are matched one-to-one with the V-shaped convex surfaces 123 on the two side arm plates 121, and both can form a positive contact relationship. Multiple intermediate arm plates 122 are correspondingly inserted between two intermediate arm plates 222 with V-shaped concave surfaces 23 formed on the opposing surfaces, so that the V-shaped convex surfaces 123 on both sides of the intermediate arm plate 122 can be matched with the V-shaped concave surfaces 23 on the two adjacent intermediate arm plates 222, and both can form a positive contact relationship. A gap is formed between the outer peripheral surface of the connecting column 13 and the side surface of the second arm plate 22, see Figures 1 to 3 shown.

[0034] The first arm plate 12 and the second arm plate 22 interlock to form a support structure, enabling the two side plates 20 to secure the wall panel 10 positioned therebetween in an upright position relative to the columns and beams, maintaining a stable state. In the event of a natural disaster such as an earthquake, which causes the entire prefabricated building to shake violently or vibrate, potentially causing the wall to collapse, the mating surfaces of the first arm plate 12 and the second arm plate 22 can slide and shift, absorbing vibration energy through friction and distributing the force, thereby preventing the wall from breaking or tilting. In other words, a chimeric connection structure can be formed between the V-shaped convex surface 123 on the side arm plate 121 and the V-shaped concave surface 23 on the side arm plate 221, as well as between the V-shaped convex surface 123 on the intermediate arm plate 122 and the V-shaped concave surface 23 on the intermediate arm plate 222, and at the same time, offset sliding can occur between the chimeric surfaces, thereby ensuring the stability and reliability of the connection structure between the side panel 20 and the wall panel 10, and achieving frictional energy absorption with the help of the offset sliding action, improving the stress condition of the wall at the connection node, reducing the vibration intensity of the wall, and suppressing the wall from breaking, deforming, tilting, and overturning at the connection node.

[0035] After the first arm plate 12 is matched with the second arm plate 22 , a gap is formed between the end surface of the second arm plate 22 and the side surface of the wall panel body 11 , that is, the length of the first arm plate 12 is greater than that of the second arm plate 22 .

[0036] Preferably, an elastic portion 132 is formed at the root of the connecting column 13, i.e., near the side of the wall panel body 11. The elastic portion 132 can cause the connecting column 13 to undergo elastic deformation, allowing the column body of the connecting column 13 to elastically deflect relative to the direction of its axial extension, thereby helping to enhance the toughness and flexibility of the connection structure established between the side panel 20 and the wall panel 10. During construction, the side panel 20 is fixedly connected to the column beam (a common structure in existing prefabricated buildings, which will not be described in detail) as a whole. When disasters such as earthquakes and strong winds or severe weather cause the entire prefabricated building (especially the column beam as the main supporting structure) to vibrate violently, and the vibration causes the side panel 20 to shake the connecting column 13 through the column beam, the column body of the connecting column 13 can form a radial buffer in the space, forming an elastic energy-absorbing structure, thereby improving the vibration resistance of the wall. At the same time, the supporting and fixing effect of the side panels 20 on the wall panels 10 can be improved, thereby improving the ability to suppress the tilting tendency of the wall, improving the earthquake resistance, and further improving safety.

[0037] An elastic sleeve 16 is fixedly mounted at the inner end of the multi-step through-hole 211, and the stud section 131 extends into the cavity of the multi-step through-hole 211 after passing through the elastic sleeve 16. The installation of the elastic sleeve 16 creates a (radial) elastic buffer zone between the contact surface between the near-free end of the connecting post 13 and the base 21, or in other words, the side panel 20. This reduces vibration energy transmitted from the side panel 20 to the wall panel 10, forming an elastic damping and energy-absorbing structure. This achieves the same or similar effects as the elastic portion 132 formed at the base of the connecting post 13 described above. Therefore, in specific embodiments, either the elastic portion 132 or the elastic sleeve 16 can be used separately or simultaneously. When both the elastic portion 132 and the elastic sleeve 16 are provided, the radial depth of the elastic portion 132 can be appropriately reduced, while the mechanical strength at the base of the connecting post 13 is appropriately increased, thereby enhancing load-bearing capacity.

[0038] To prevent the first arm plate 12 and the second arm plate 22 from sliding and shifting, thereby preventing excessive relative thrust from being generated therebetween, which could cause irreversible deformation of the first arm plate 12 and / or the second arm plate 22, a second elastic portion 24 is preferably formed at the root of a portion of the second arm plate 22, such as only at the root of the second intermediate arm plate 222 and on the side wall opposite the V-shaped concave surface 23. The second elastic portion 24 enables the second arm plate 22, or the second intermediate arm plate 222, to elastically deform, allowing the plate body of the second arm plate 22 to elastically deflect in the direction of the inner concave depth of the V-shaped concave surface 23. This helps enhance the connection toughness and mechanical flexibility of the interlocking structure formed between the first arm plate 12 and the second arm plate 22, thereby improving the vibration resistance of the wall.

[0039] The second elastic portion 24 may be a linear groove with a curved inner bottom surface. This linear groove may be a linear groove region formed by a plurality of linear grooves spaced apart along the length of the second intermediate arm plate 222, or a single linear groove. When the second elastic portion 24 is formed as a linear groove region, the depth of each linear groove can be appropriately reduced, thereby better balancing the mechanical strength, support rigidity, and toughness of the second intermediate arm plate 222.

[0040] A plurality of elastic ridges 124 are alternately distributed on the two inclined surfaces of the V-shaped convex surface 123. After the V-shaped convex surface 123 is matched with the V-shaped concave surface 23, the elastic ridges 124 can be sandwiched in the middle. After the elastic ridges 124 are distributed, an elastic buffer space can be formed between the V-shaped convex surface 123 and the V-shaped concave surface 23, that is, an elastic buffer space is formed between the first arm plate 12 and the second arm plate 22. On the one hand, it can reduce the load borne by the first arm plate 12 and the second arm plate 22 when relative displacement and sliding occur, avoid excessive load, further improve safety performance, and ensure the reliability, stability and stability of the support and fixation of the side plate 20 to the wall plate 10; on the other hand, it can form an elastic damping energy absorption structure, which has the same or similar effect as the elastic part 24 formed on the second arm plate 22; in addition, after the elastic ridges 124 are provided between the V-shaped convex surface 123 and the V-shaped concave surface 23, the first arm plate 12 and the second arm plate 22 can be increased. The connection viscosity between the interlocking contact surfaces of the two arm plates 22 can improve the firmness and stability of the connection structure; it can also easily cause misalignment and sliding with the help of the elastic deformation of the elastic protrusion 124, and the elastic blocking force will be converted into an elastic pulling force that forces the first arm plate 12 to return to the second arm plate 22 after the misalignment and sliding amount reaches a certain extent, and oscillation energy absorption is generated between the first arm plate 12 and the second arm plate 22, so that its damping and vibration absorption capacity is improved, and it can better suppress the (assembled) wall from tilting, overturning and other accidents, thereby improving safety.

[0041] The elastic ridge 124 is fixedly mounted on the V-shaped convex surface 123 of the first arm plate 12. The radial or cross-sectional shape of the elastic ridge 124 is cylindrical or elliptical. The base 21 is formed with a wing plate 212 fixedly connected to the external main beam. The wing plate 212 is provided with through holes for bolts to pass through.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. The present invention can be improved in many aspects without violating the overall concept. Those skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed by the present invention shall be covered by the claims of the present invention.
