Description

Technical Field

[0001] The present invention relates to the technical field of assembled wall panels, and in particular to an assembled building wall panel and a production method thereof. Background Art

[0002] With the rising labor costs and the rapid development of the construction market, higher requirements are put forward for the industrialized production, standardized construction and recyclability of buildings. Therefore, prefabricated buildings have emerged as a new type of construction method and have gradually become a hot spot and trend in the construction industry. Prefabricated buildings refer to the transfer of a large number of on-site operations in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated buildings require partition walls to separate the building space into different rooms. Prefabricated wall panels are important partition components for separating rooms in prefabricated buildings. This type of wall panel not only has the characteristics of stable structure, good decorative effect, and excellent thermal insulation performance, but also greatly improves construction efficiency and reduces construction costs, which is in line with the concept of green buildings and energy conservation and emission reduction.

[0003] When the assembled wall panels on the market are currently connected, the adjacent wall panels are connected by tongue-and-groove connection. The tongue-and-groove connection is not fixed after being snapped together, which makes the connection strength between the adjacent wall panels low and prone to cracks. For example, in the prior art, Chinese patent announcement No. CN110469049A discloses a building wall, in which the adjacent wall panels are fixed by plug-in pieces during installation, which makes it difficult to ensure the connection strength. Moreover, there is a gap between the butt surfaces of the adjacent wall panels after they are spliced. The existing method of applying a coating on the wall surface cannot ensure the sealing effect between the gaps. Therefore, it is very necessary to improve the existing wall panels.

[0034] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0037] like Figure 1-Figure 6 As shown, a building assembled wall panel comprises a wall panel body 1 made of concrete, both ends of the wall panel body 1 are provided with connecting plates 11 integrally formed with the wall panel body 1, the connecting plates 11 at both ends of the wall panel body 1 are respectively close to the front and rear surfaces of the wall panel body 1, and the connecting plate 11 at one end of the wall panel body 1 is rotated 180° to be consistent with the connecting plate 11 at the other end so that when adjacent wall panel bodies 1 are connected, the connecting plates 11 on adjacent wall panel bodies 1 are butted against each other and buckled into a flat plate of the same thickness as the wall panel body 1;

[0038] A locking plate 2 is arranged in the connecting plate 11, a threaded hole 21 is opened on the locking plate 2, a first through hole 111 coaxial with the threaded hole 21 is opened on the connecting plate 11, and a second through hole 112 is opened on the connecting plate 11. The second through hole 112 is matched with the first through hole 111 in position so that when the wall panel bodies 1 are spliced, the first through hole 111 on the wall panel body 1 is coaxial with the second through hole 112 on the connecting plate 11 of the adjacent wall panel body 1, so that the connecting bolt 7 passes through the second through hole 112, and the first through hole 111 is threadedly connected with the locking plate 2 to lock the connecting plates 11 on the adjacent wall panel bodies 1 to each other.

[0039] By adopting the above technical solution, by setting the connecting plate 11, the wall panel body 1 can be spliced ​​and connected together through the connecting plate 11 when splicing, and the connecting bolt 7 passes through the second through hole 112 and the first through hole 111 and cooperates with the locking plate 2 threadedly, so that the connecting plates 11 on adjacent wall panel bodies 1 are locked to each other, so that the adjacent wall panel bodies 1 are locked to each other, thereby improving the connection strength and avoiding cracking of the splicing seams due to deformation of the adjacent wall bodies.

[0040] Specifically, the connecting plate 11 is provided with a butt joint surface and a flush surface 12, the flush surface 12 is coplanar with the surface of the wall panel body 1, the butt joint surface is provided with a concave groove 13, a convex joint 14 and an inclined surface 15 connecting the concave groove 13 and the convex joint 14, the open side width of the concave groove 13 is greater than the bottom width, the concave groove 13 is located on the side of the convex joint 14 close to the center of the wall panel body 1, and the convex joint 14 is rotated 180° to be consistent with the concave groove 13 so that when adjacent wall panel bodies 1 are spliced, the convex joint 14 is clamped in the concave groove 13 of the wall panel body 1 to form a complete plate structure. The connecting plates 11 on adjacent wall panel bodies 1 are mutually fitted and engaged through the concave groove 13 and the convex joint 14, and the mutually fitted structure is not easy to be misaligned, thereby maintaining a more stable connection.

[0041] Specifically, a fixing box 3 is fixed in the connecting plate 11, and the fixing box 3 is a hollow structure. The fixing box 3 is located in the convex joint 14, and the second through-hole 112 is located in the concave groove 13 and passes through the connecting plate 11; the locking plate 2 is located in the fixing box 3 and slidably cooperates with the fixing box 3 so that the locking plate 2 can be axially translated along the first through-hole 111, thereby ensuring that the locking plate 2 cannot rotate during the rotation and tightening process of the connecting bolt 7 and the locking plate 2; a compression spring 31 is arranged in the fixing box 3, and the compression spring 31 is located on the side of the locking plate 2 close to the first through-hole 111, the inner diameter of the compression spring 31 is larger than the aperture of the first through-hole 111 and is coaxial with the first through-hole 111, one end of the compression spring 31 is fixedly connected to the locking plate 2, and the other end of the compression spring 31 is fixedly connected to the inner wall of the fixing box 3, and the first through-hole 111 passes through the inner wall of the fixing box 3 so that the connecting bolt 7 passes through the first through-hole 111 and is threadedly connected to the locking plate 2 in the fixing box 3 during splicing. The elastic force provided by the compression spring 31 is used as a pre-tightening force, so that the tension between the locking plate 2 and the connecting bolt 7 remains after being locked, thereby preventing the locking plate 2 and the connecting bolt 7 from loosening and causing locking failure.

[0042] Specifically, the locking plate 2 is provided with an annular mounting groove 22, and one end of the compression spring 31 close to the locking plate 2 is located in the annular mounting groove 22. The annular mounting groove 22 is provided, and the locking plate 2 moves toward the first through hole 111 in the locked state so that the compression spring 31 can be accommodated in the annular mounting groove 22 when compressed.

[0043] Specifically, the connecting plate 11 is provided with a countersunk hole 113, which is located at the end of the second through hole 112 away from the concave groove 13. The countersunk hole 113 can avoid the nut of the connecting bolt 7, so that the outer end of the connecting bolt 7 does not protrude from the plate surface of the connecting plate 11, so that the outer plate surface remains flat.

[0044] Specifically, a partition 32 is fixedly connected in the fixed box 3, a receiving bag 4 is arranged between the isolation plate in the fixed box 3 and the inner wall of the fixed box 3, the receiving bag 4 is filled with adhesive, an extrusion plate 23 is fixedly connected to the locking plate 2, the extrusion plate 23 is located on the side of the receiving bag 4 away from the first perforation 111, a glue injection tube 33 is fixedly connected to the side wall of the fixed box 3, one end of the glue injection tube 33 extends to the outside of the connecting plate 11, and the other end of the glue injection tube 33 extends into the fixed box 3 and toward the receiving bag 4, when locked, the locking plate 2 moves toward the first perforation 111 to squeeze the receiving bag 4 so that the internal adhesive is squeezed out and injected from the glue injection tube 33 into the splicing gap between adjacent wall panel bodies 1. By arranging a receiving bag 4 filled with adhesive in the fixed box 3 and fixedly connecting it to the locking plate 2 through the extrusion plate 23, the locking plate 2 can squeeze the adhesive into the splicing gap during the locking process, so that the splicing seam is injected and bonded during the assembly process, making the splicing more firm, and the adhesive is directly injected into the splicing gap, and the adhesive spreads in the gap to fill and bond the inside of the gap, thereby maintaining firm bonding and better sealing. Specifically, a piercing needle is fixedly connected to one end of the injection tube 33 close to the fixed box 3 to break the receiving bag 4 during the squeezing, so that the receiving bag 4 can be ruptured after squeezing.

[0045] Specifically, the connecting plate 11 is provided with a steel pipe 5, the steel pipe 5 is fixedly connected to the fixing box 3 and the inner cavity of the steel pipe 5 is communicated with the inner cavity of the fixing box 3, the steel pipe 5 extends to the inclined surface 15, the steel pipe 5 is provided with an ejector pin 51 that slides with the steel pipe 5, one end of the ejector pin 51 extends into the fixing box 3 and is fixedly connected with an ejector ball 52; the side of the locking plate 2 is provided with an inclined pressing surface 24, when the locking plate 2 moves toward the first through hole 111, the pressing surface 24 contacts the ejector ball 52 and ejects the ejector pin 51 toward the concave groove 13. When the locking plate 2 is locked, it moves toward the first through hole 111, and the pressing surface 24 moves toward the first through hole 111, so that the ejector pin 51 is inserted into the adjacent connecting plate 11, thereby making the connection between the adjacent wall panel bodies 1 more firm.

[0046] Specifically, the ejector pin 51 is sleeved with a second spring 53, one end of which is fixed on the ejector ball 52, and one end of which is fixed on the inner wall of the fixing box 3. The second spring 53 keeps the ejector pin 51 in a relatively stable position when the ejector ball 52 is not under pressure, so as to prevent the ejector pin 51 from extending or retracting into the fixing box 3. When the ejector ball 52 is under pressure during the splicing and installation process, the second spring 53 contracts, so that the ejector pin 51 extends from the steel pipe 5 and penetrates into the connecting plate 11 of the adjacent wall panel body 1 in the concave groove 13, thereby fixing the connecting plate 11.

[0047] Specifically, the wall panel body 1 is further provided with a steel frame skeleton 6, the fixing box 3 is fixedly connected to the steel frame skeleton 6, the steel frame skeleton 6 is fixedly connected with a first sleeve 61, the countersunk hole 113 and the second through hole 112 are arranged in the sleeve; the fixing box 3 is fixedly connected with a second sleeve 62, and the first through hole 111 is arranged in the first sleeve 61. The sleeve is provided to facilitate the formation of the countersunk hole 113, the second through hole 112, and the first through hole 111 during casting, so as to avoid clogging the countersunk hole 113, the second through hole 112, and the first through hole 111.

[0048] Specifically, the steel frame skeleton 6 is fixedly connected with foam blocks 63, which are made of thermal insulation material polystyrene foam, and are arranged at intervals. By providing the foam blocks 63, the wall panel body 1 is made light and thermally insulating. At the same time, due to the interval arrangement of the foam blocks 63, the concrete pouring layers on both sides of the steel frame skeleton 6 in the wall panel body 1 are connected to form a box beam structure, thereby reducing the pouring materials, achieving lightness, and improving the overall strength; it also avoids the use of a complete thermal insulation layer, which causes the upper and lower layers of the wall panel body 1 on both sides of the steel frame skeleton 6 to be disconnected, resulting in weak overall strength.

[0049] On the other hand, an embodiment of the present invention further provides a method for producing a building assembled wall panel, which is used to produce the above-mentioned building assembled wall panel. The production method comprises the following steps:

[0050] 1. Apply butter to the countersunk hole 113 and the second through hole 112 in the first sleeve 61 and the first through hole 111 in the second sleeve 62 to seal the outer ends of the holes; by applying butter to the outer ends of the holes, it is prevented that the casting material enters the holes and blocks the holes during casting, and the applied butter can lubricate and rust the holes and the connecting bolts 7 during installation and splicing;

[0051] 2. Place the steel frame skeleton 6 and the accessories fixedly connected to the steel frame skeleton 6 on the mold bottom plate 8, on which the mold bottom plate 8 is provided a core template 81 for molding the connecting plate 11 at one end of the wall panel body 1;

[0052] 3. A mold side plate 82 is provided on the mold bottom plate 8, and a limiting column 83 is provided on the mold side plate 82. The mold side plate 82 is pushed so that the mold side plate 82 is close to the steel frame 6, and the limiting column 83 is inserted into the tube hole of the injection tube 33, as shown in FIG. Figure 7 , 8As shown, the end of the glue injection tube 33 is blocked, and the steel frame skeleton 6 is supported to be lifted and in a suspended state; the limit column 83 is inserted into the glue injection tube 33 to block the end of the glue injection tube 33, thereby preventing the pouring concrete from entering the glue injection tube 33 and causing blockage, and at the same time supporting the steel frame skeleton 6, thereby preventing the steel frame skeleton 6 from falling on the mold bottom plate 8, ensuring the casting and forming below the steel frame skeleton 6, and at the same time limiting the upper and lower positions of the steel frame skeleton 6, preventing the steel frame skeleton 6 from being dislocated and floating during the casting process, and ensuring the stability of the position of the steel frame skeleton 6 buried in the wall panel body 1;

[0053] 4. Cover the core template 81 formed by the connecting plate 11 at the other end of the wall panel body 1 on the top of the mold bottom plate 8, and enclose the mold bottom plate 8 around the casting cavity for forming the wall panel body 1;

[0054] 5. Fill the casting cavity with concrete, drive the mold bottom plate 8 to vibrate to fill the inside, and scrape the upper surface of the wall panel body 1 flat;

[0055] 6. After pouring, let it stand until the cement has initially set and take shape. After the initial setting, remove the mold and let it stand until the cement has finally set to complete the production.
