Description

Technical Field

[0001] This invention relates to the field of prefabricated walls, and more particularly to a concealed assembly prefabricated wall panel structure. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] Precast wall panels are common components in prefabricated buildings. To facilitate their fabrication and construction, the width of precast wall panels is generally limited to a certain range. Since the width of the walls to be constructed varies, it is often necessary to splice and fix two or more precast wall panels together. Traditionally, this is achieved by butt-jointing with reinforcing bars. However, due to the large weight of precast wall panels, this method negatively impacts the splicing process, resulting in slower construction efficiency and higher risks.

[0004] Therefore, it is necessary to provide a new concealed assembly prefabricated wall panel structure to solve the above-mentioned technical problems. Summary of the Invention

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 ,in, Figure 1 A schematic diagram of a preferred embodiment of the concealed assembly prefabricated wall panel structure provided by the present invention; Figure 2 This is a schematic diagram of the internal structure of the wall panel provided by the present invention; Figure 3 This is one of the schematic diagrams of the docking mechanism provided by the present invention; Figure 4 This is the second schematic diagram of the docking mechanism structure provided by the present invention; Figure 5 This is a schematic diagram of the snap-fit ​​mechanism provided by the present invention; Figure 6 This is one of the schematic diagrams of the force-fixing mechanism provided by the present invention; Figure 7 This is the second schematic diagram of the force-fixing mechanism provided by the present invention; Figure 8 This is a schematic diagram of the connection mechanism provided by the present invention. It includes: a wall panel 1 and a steel mesh 11.

[0029] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a steel mesh 11 is laid inside the wall panel 1. A meshing and transmission limiting docking mechanism 2 is symmetrically installed at the top and bottom of the wall panel 1. A positioning and fastening fixing mechanism 3 is symmetrically installed on the side of the wall panel 1. A bonding plate 4 is provided on the side of the wall panel 1. A connecting mechanism 5 that can penetrate and tighten the wall panel 1 is installed on the surface of the bonding plate 4 between the fixing mechanisms 3.

[0030] The wall panel 1 and the steel mesh 11 together form a stable wall surface. Adjacent wall panels 1 are quickly connected by the docking mechanism 2. The strength of the connection of wall panels 1 is increased by the fixing mechanism 3. Then, the connection part of the wall panel 1 is sealed by the bonding plate 4 and the connecting mechanism 5, so that the wall panel 1 forms a flat and integrated appearance.

[0031] refer to Figure 3 and Figure 4 As shown, the docking mechanism 2 includes a snap-fit ​​mechanism 21, a docking post 22, a connecting plate 23, a docking cylinder 24, and a through hole 25. The docking post 22 and the docking cylinder 24 are respectively embedded and fixed on both sides of the wall panel 1. The snap-fit ​​mechanism 21 is connected and fixed to the inner end of the docking post 22. The connecting plate 23 is fixed between the snap-fit ​​mechanism 21 and the docking cylinder 24. The connecting plate 23 has through holes 25 equidistantly opened on its surface, and the top of the steel mesh 11 is inserted into the through hole 25.

[0032] By inserting the connecting column 22 and the connecting cylinder 24 at adjacent positions, the wall panel 1 can be quickly positioned. The connecting column 22 and the connecting cylinder 24 are locked by the fastening and locking mechanism 21, thus ensuring the first step of the fixed connection of the wall panel 1. The through hole 25 on the surface of the connecting plate 23 is connected to the steel mesh 11, which increases the installation strength of the connecting mechanism 2.

[0033] refer to Figure 5 As shown, the snap-fit ​​mechanism 21 includes a housing 211, a worm gear 212, a worm wheel 213, a transmission rod 214, a threaded cylinder 215, a connecting column 216, a ball groove 218, a connecting rod 219, a return spring 210, and a ball block 2101. The housing 211 is fixedly connected to the docking column 22. The transmission rod 214 is rotatably mounted inside the housing 211, and the worm wheel 213 is fixed outside the transmission rod 214. The worm gear 212 is rotatably mounted inside the housing 211, and the worm gear 212 is meshed with the worm wheel 213. The end of the transmission rod 214 is located at the docking column 210. 2. A threaded cylinder 215 is fixed inside. Ball blocks 2101 are symmetrically slidably inserted inside the docking post 22. A return spring 210 is fixed between the ball blocks 2101. A connecting rod 219 is rotatably connected to the inner surface of the ball blocks 2101. A connecting post 216 is provided inside the docking post 22. The connecting rod 219 is rotatably connected to the connecting post 216. An external thread is provided at the end of the connecting post 216 near the threaded cylinder 215. The connecting post 216 is meshed with the threaded cylinder 215 through the external thread. Ball grooves 218 that cooperate with the ball blocks 2101 are symmetrically provided on the inner wall of the docking cylinder 24.

[0034] After the docking post 22 and the docking cylinder 24 are inserted, use a wrench to rotate the worm gear 212. Through the meshing transmission of the worm wheel 213, the transmission rod 214 drives the threaded cylinder 215 to rotate. Through the threaded engagement of the threaded cylinder 215 with the connecting post 216, the connecting post 216 moves. Through the linkage of the connecting rod 219, the ball block 2101 expands outward and engages with the ball groove 218, thus completing the locking of the connection between the docking post 22 and the docking cylinder 24.

[0035] The inner wall of the docking post 22 is fixed with a collar 217, and the connecting post 216 is slidably inserted into the collar 217. The collar 217 limits the sliding movement of the docking post 22, thereby increasing the stability of the linear movement of the docking post 22.

[0036] In addition, the end of the worm gear 212 rotates out of the surface of the encapsulation shell 211, and the outer end of the worm gear 212 is provided with a hexagonal groove, which makes it convenient to use a wrench to turn the worm gear 212.

[0037] refer to Figure 6 and Figure 7As shown, the fixing mechanism 3 includes an installation groove 31, a positioning cylinder 32, a fixing plate 33, a positioning column 34, a block 35, a support plate 36, a slot 37, and fixing holes 38. The wall panel 1 has an installation groove 31 on its side. The positioning cylinder 32 is symmetrically embedded and fixed at the bottom of the installation groove 31. The fixing plate 33 is fixed on the side of the positioning cylinder 32. The fixing holes 38 are equidistantly opened on the surface of the fixing plate 33, and the steel mesh 11 is connected to the fixing holes 38. The block 35 is placed in the installation groove 31. The positioning column 34 is symmetrically fixed at the bottom of the block 35, and the positioning column 34 is inserted into the positioning cylinder 32. The top of the block 35 has a slot 37 symmetrically opened, and the support plate 36 is engaged in the slot 37.

[0038] Place block 35 inside mounting groove 31, and insert positioning post 34 into positioning cylinder 32 accordingly. When block 35 moves down to the bottom of mounting groove 31, insert support plate 36 into slot 37 to limit the top of block 35, preventing positioning post 34 from being pulled out of positioning cylinder 32, thus completing the reinforced connection of wall panel 1. Through the connection of reinforcement hole 38 and steel mesh 11, the positioning strength of positioning cylinder 32 is increased.

[0039] refer to Figure 8 As shown, the connecting mechanism 5 includes a through-hole 51, a screw 52, ​​a screw 53, and a countersunk groove 54. The through-hole 51 is provided on the edge of the wall panel 1. The screw 52 is fixed on the surface of the bonding plate 4 on one side of the wall panel 1, and the countersunk groove 54 is provided on the surface of the bonding plate 4 on the other side of the wall panel 1. The screw 53 is inserted into the countersunk groove 54. The screw 52 and the screw 53 are inserted into the through-hole 51 respectively, and the screw 52 and the screw 53 are engaged and connected.

[0040] Cover the two sides of the mating part of the wall panel 1 with the bonding plate 4, insert the screw spool 52 into the through hole 51, and pass the screw 53 through the countersunk groove 54 to engage with the screw spool 52 until the bonding plate 4 is locked onto the surface of the wall panel 1, forming a seal for the mating part of the wall panel 1.

[0041] refer to Figure 8 As shown, the side of the wall panel 1 is in a trapezoidal concave-convex fit, so that the wall panel 1 is neatly and stably joined together. The side of the surface of the wall panel 1 is provided with a fitting groove 12, and the fitting plate 4 is engaged with the fitting groove 12 to ensure that the outer surface of the fitting plate 4 is flush with the fitting groove 12, forming a neat surface.

[0042] The working principle of the concealed assembly prefabricated wall panel structure provided by this invention is as follows: When assembling the wall panel 1, the wall panel 1 can be quickly positioned by inserting the connecting columns 22 and connecting cylinders 24 at adjacent positions. The connecting columns 22 and connecting cylinders 24 are locked by the fastening and locking mechanism 21, thereby ensuring the first step of fixing and connecting the wall panel 1. The through holes 25 on the surface of the connecting plate 23 are connected to the steel mesh 11, increasing the installation strength of the connecting mechanism 2. Then, the block 35 is placed inside the installation groove 31, and the positioning column 34 is inserted into the positioning cylinder 32 accordingly. When the block 35... Move the support plate 36 to the bottom of the mounting groove 31 and insert it into the slot 37 to limit the top of the block 35, preventing the positioning post 34 from being pulled out of the positioning cylinder 32, thus completing the reinforced connection of the wall panel 1. The connection between the support plate 36 and the steel mesh 11 through the fixing hole 38 increases the strength of the positioning cylinder 32. Finally, cover the two sides of the mating part of the wall panel 1 with the bonding plate 4, insert the screw spool 52 into the through hole 51, and insert the screw 53 through the countersunk groove 54 to engage with the screw spool 52 until the bonding plate 4 is locked onto the surface of the wall panel 1, forming a seal for the mating part of the wall panel 1.
