Description

Technical Field

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

[0002] Prefabricated buildings are buildings formed by transporting components pre-produced in the workshop to the construction site and assembling them on site. The advantages of this construction method are fast construction speed, high efficiency, easy standardization, and relatively little impact from external conditions such as climate. Prefabricated walls are the main structure of prefabricated buildings. When they are fixed between columns and beams, the wing plates set on the edge of the wall panels and the column beams are connected by bolts, and the wing plates between the wall panels are connected to each other. The connection structure formed is a rigid connection structure. The overall rigidity of the prefabricated wall fixed between two columns and beams is relatively large, and the ability to resist natural disasters such as earthquakes and typhoons is relatively poor. It is easy to cause serious deformation or even fracture at the connection position between the wall panels and the wall panels and between the wall panels and the column beams, resulting in obvious tilting, collapse and other accidents of the wall. Moreover, the larger the area of ​​the prefabricated wall formed between the columns and beams, the weaker its ability to resist natural disasters such as earthquakes and typhoons. It is not suitable for the construction of large buildings, or if the wall area of ​​the building is large, the distribution 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, which overcomes the problem of poor ability of prefabricated walls to resist natural disasters such as earthquakes and typhoons by optimizing the wall panel structure of the prefabricated wall, helps to make the prefabricated wall have better damping and vibration resistance, and has a simple design structure, few accessories, and easy and quick installation.

[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 surfaces of the wall panel body, and the two side panels are matched with the left side and the right side surfaces of the wall panel body respectively. The first arm plate on each side includes two side arm plates 1 and a plurality of middle arm plates 1, and the middle 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 two side end surfaces of the middle arm plate 1 are formed into V-shaped convex surfaces. The connecting columns are distributed between adjacent side arm plates 1 and middle arm plates 1, and between two adjacent middle 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 a spring is sleeved on the stud section and a nut portion is matched therewith.

[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, and the intermediate arm plates 2 are alternately distributed between the two side arm plates 2. The outer end surface of the side arm plate 2 and one side end surface of the intermediate arm plate 2 are both formed into a V-shaped concave surface, that is, the outer end surface of the side arm plate 2 and the opposite end surfaces of the two relatively adjacent intermediate arm plates 2 are both formed into a V-shaped concave surface.

[0007] A plurality of multi-step through holes extending axially along the length direction of the second arm plate and corresponding to the connecting column are formed on the base. The stud section on the connecting column extends into the multi-step through hole, so that the spring and the nut part can be accommodated in the cavity of the multi-step through hole, and one end of the spring contacts the bottom surface of the multi-step through hole, and the other end contacts the end surface of the nut part.

[0008] The V-shaped concave surfaces on the two side arm plates 2 are matched one by one with the V-shaped convex surfaces on the two side arm plates 1 and form a profile fit relationship. The plurality of intermediate arm plates 1 are respectively inserted between the plurality of adjacent intermediate arm plates 2 whose opposite surfaces are formed as V-shaped concave surfaces, and the V-shaped convex surfaces on both sides of the intermediate arm plate 1 can be matched with the V-shaped concave surfaces on the two adjacent intermediate arm plates 2 and form a profile fit relationship. A gap is formed between the outer peripheral surface 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 part 1 is formed at the root of the connecting column. The elastic part 1 can cause the connecting column to elastically deform from its root, so that the column body of the connecting column is elastically offset relative to its axial extension direction. The elastic part 1 can be an annular groove, and the inner bottom surface of the groove is a curved 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, at least at the root of part of the second arm plate, such as only at the root of the second intermediate arm plate and on the other side opposite to the side with the V-shaped concave surface, a second elastic part is formed. The second elastic part can make the second arm plate or the plate body of the second intermediate arm plate elastically deflect from the root along the inner concave depth direction of the V-shaped concave surface, which helps to enhance the connection toughness of the interlocking structure formed between the first arm plate and the second arm plate and improve the detour deflection.

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

[0014] Optionally, a plurality of elastic convex strips are alternately distributed on the two 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 convex strips or elastic pads can be sandwiched in the middle.

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

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

[0017] The beneficial effects of the present invention are as follows: the present invention helps to overcome the problem of poor ability of the prefabricated wall to resist natural disasters such as earthquakes and typhoons by optimizing the wall panel structure of the prefabricated wall, and helps to promote the prefabricated wall to have better damping and vibration resistance, so that its vibration resistance and safety performance are significantly improved, so it is called a safe prefabricated wall. In addition, the prefabricated wall involved in the present invention has a simple design structure, contains fewer types of accessories, and is convenient and quick to install and disassemble.

[0024] The structures, proportions, sizes, etc. illustrated in the drawings of the specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "front", "back", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical contents.

[0025] like Figures 1 to 5 A safe assembled wall body shown in the figure comprises a wall panel 10 and a pair of side panels 20, wherein the two side panels 20 are arranged oppositely on the left and right sides of the wall panel 10. In specific implementation, a pair of side panels 20 can also be arranged on the upper and lower sides of the wall panel 10, so the present invention includes an implementation situation 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 opposite side surfaces (i.e., the left side surface and the right side surface of the wall panel body 11 shown in the figure) of the wall panel body 11. Two side panels 20 correspond to and match the two side surfaces of the wall panel body 11 on which the first arm panels 12 and the connecting columns 13 are provided. When the side panels 20 are correspondingly arranged on the upper side surface and the lower side surface of the wall panel body 11 at the same time, it is necessary to arrange a plurality of first arm panels 12 and a plurality of connecting columns 13 on both the upper side surface and the lower side surface of the wall panel body 11, that is, a plurality of first arm panels 12 and a plurality of connecting columns 13 are arranged on two pairs of opposite side surfaces of the wall panel body 11. It is preferred that the number of the first arm panels 12 and the number of the connecting columns 13 respectively arranged on the two opposite side surfaces are consistent.

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

[0028] The connecting column 13 is distributed between two adjacent first arm plates 12, that is, the connecting column 13 is distributed between the adjacent side arm plates 121 and the intermediate arm plates 122, and between two adjacent intermediate arm plates 122. One end of the connecting column 13 is fixedly matched with the wall panel body 11. The fixed matching here includes the situation where a fixed matching relationship is established by a fixed connection method, and includes the situation where a fixed matching relationship is formed by an integrally formed structure 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, and the stud section 131 is sleeved with a spring 14 and matched with a nut portion 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 into a V-shaped concave surface 23, that is, the outer end surface of the side arm plate 221 and the opposite end surfaces of the two relatively adjacent (i.e. partially adjacent) intermediate arm plates 222 are both formed into a V-shaped concave surface 23. The two V-shaped concave surfaces 23 located on the opposite surfaces of the two relatively adjacent intermediate arm plates 222 can be matched with the two V-shaped convex surfaces 123 on the intermediate arm plate 122 inserted between the two, forming a profile contact type plug-in connection structure, see Figure 2 , Figure 4 , Figure 5 .

[0031] A plurality of multi-step through holes 211 extending axially along the length direction of the second arm plate 22 and correspondingly matching with the connecting column 13 are formed on the base 21. The stud section 131 on the connecting column 13 extends into the multi-step through hole 211, so that the spring 14 and the nut portion 15 can be accommodated in the cavity of the multi-step through hole 211, and one end of the spring 14 contacts the inner bottom surface of the multi-step through hole 211, and the other end contacts the end surface of the nut portion 15. When the nut portion 15 is screwed to adjust the axial position of the nut portion 15 relative to the stud section 131, the compression degree of the spring 14 can be adjusted, and the connection tension applied by the spring 14 on the connecting column 13 can be adjusted, so that the opposite ends of the side plate 20 and the wall plate 10 can be tightly pressed and matched, and there is a certain (elastic) floating distance between the opposite surfaces.

[0032] An annular body is formed on the outer end surface of the nut portion 15, and the outer circumferential surface of the annular body is formed into a prism surface, and 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 with the V-shaped convex surfaces 123 on the two side arm plates 121 one by one and can form a contact and matching relationship. A plurality of intermediate arm plates 122 are correspondingly inserted between two intermediate arm plates 222 whose opposite surfaces are formed with V-shaped concave surfaces 23, and 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 can form a contact and matching 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] After the first arm plate 12 and the second arm plate 22 are cross-matched, a support structure can be formed, so that the two side plates 20 can fix the wall plate 10 disposed therebetween vertically relative to the column beam and maintain a stable state. When encountering natural disasters such as earthquakes, which cause the entire prefabricated building to shake / vibrate violently and cause the wall to collapse, the first arm plate 12 and the second arm plate 22 can slide between the relative matching surfaces, and the vibration energy can be absorbed by friction, and the force can be dispersed to suppress the tendency of the wall to break and tilt. 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 middle arm plate 122 and the V-shaped concave surface 23 on the middle 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 plate 20 and the wall plate 10, and achieving friction energy absorption by means 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 the length of the second arm plate 22 .

[0036] Preferably, an elastic part 132 is formed at the root of the connecting column 13, that is, near the side position of the wall panel body 11. The elastic part 132 can cause the connecting column 13 to produce elastic deformation, so that the column body of the connecting column 13 can be elastically offset relative to the extension direction of its axis, which helps to enhance the toughness and flexibility of the connection structure established between the side plate 20 and the wall panel 10. During construction, the side plate 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 encountering disasters such as earthquakes, strong winds or bad weather, causing the entire prefabricated building (especially the column beam as the main supporting structure) to vibrate violently, and the vibration causes the side plate 20 to pull the connecting column 13 to shake through the column beam, the column body of the connecting column 13 can form a buffer in the radial direction in the space, forming an elastic energy absorption structure, and can improve 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, the ability to suppress the tilting tendency of the wall can be improved, the earthquake resistance can be improved, and the safety can be further improved.

[0037] An elastic sleeve 16 is fixedly provided at the inner end of the multi-step through hole 211, and the stud section 131 is extended into the cavity of the multi-step through hole 211 after passing through the elastic sleeve 16. After the elastic sleeve 16 is provided, a (radial) elastic buffer zone can be formed between the contact surface between the near free end side of the connecting column 13 and the base 21 or the side plate 20, which can reduce the vibration energy transmitted from the side plate 20 to the wall plate 10, forming an elastic damping energy absorption structure. The same or similar effect can be achieved by forming an elastic part 132 at the root of the connecting column 13 as described above. Therefore, in a specific implementation scheme, the elastic part 132 and the elastic sleeve 16 can be used selectively or simultaneously. When the elastic part 132 and the elastic sleeve 16 are provided at the same time, the radial depth of the elastic part 132 can be appropriately reduced, and the mechanical strength at the root of the connecting column 13 can be appropriately increased to improve the bearing capacity.

[0038] In order to avoid the first arm plate 12 and the second arm plate 22 from sliding and shifting each other, generating an excessive relative thrust between the two, which may cause irreversible deformation of the first arm plate 12 and / or the second arm plate 22, it is preferred that an elastic part 24 is formed at the root of part of the second arm plate 22, such as the elastic part 24 is formed only at the root of the second intermediate arm plate 222 and on the other side wall surface away from the V-shaped concave surface 23. The elastic part 24 can cause the second arm plate 22 or the second intermediate arm plate 222 to generate elastic deformation, so that the plate body of the second arm plate 22 can be elastically offset in the inner concave depth direction of the V-shaped concave surface 23, which helps to enhance the connection toughness and mechanical deflection of the interlocking structure formed between the first arm plate 12 and the second arm plate 22, and helps to improve the vibration resistance of the wall.

[0039] The second elastic part 24 may be a linear groove part with a curved inner bottom surface, and the linear groove part may be a linear groove area formed by a plurality of linear grooves distributed alternately in the length direction of the second intermediate arm plate 222, or may be a single linear groove. When the second elastic part 24 is formed as a linear groove area, the groove depth of each linear groove can be appropriately reduced, that is, at this time, the mechanical strength, support rigidity and toughness of the second intermediate arm plate 222 can be better taken into account.

[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 size borne by the first arm plate 12 and the second arm plate 22 when relative displacement and sliding occur, avoid excessive load, and further improve the safety performance to 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 role 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 convex strips 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 convex strip 124 is fixedly embedded on the V-shaped convex surface 123 on the first arm plate 12. The radial section or cross section of the elastic convex strip 124 is cylindrical or elliptical. A wing plate 212 fixedly connected to the external main beam is formed on the base 21, and through holes for bolts to pass through are distributed on the wing plate 212.

[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, and those familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
