[0004] However, the above technical solution still has the following defects: by clamping the fixing strip on the right side of the panel, overlapping the card plates on both sides of the fixing strip, and overlapping the main positioning rods, card blocks, etc., the installation of the panel on site becomes complicated, and the panels are indirectly connected, thereby reducing the splicing rate of the wall on the construction site and affecting the construction efficiency of the wall. Summary of the invention

[0005] The utility model aims to provide a connection structure for assembled building walls, aiming to solve the problem in general technology that the process of splicing wall panels into walls at the construction site is relatively complicated, which affects the construction efficiency.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the connection structure of an assembled building comprises a wall panel, and a plurality of mounting columns are arranged on both adjacent end surfaces of the wall panel, and the plurality of mounting columns are evenly distributed on the end surfaces of the wall panel, and a plurality of the mounting columns are vertically arranged on the wall panel, and a plurality of mounting grooves are provided on the two end surfaces of the wall panel opposite to the two end surfaces provided with the mounting columns, and the number of the mounting grooves is the same as the number of the mounting columns, and the mounting columns of the adjacent wall panels are inserted into the mounting grooves, and a threaded hole is provided on the end surface of the wall panel perpendicular to the end surface provided with the mounting groove, and one end of the threaded hole in the length direction passes through the end surface of the wall panel, and the threaded hole passes through the mounting groove, and the mounting column is provided with a connecting hole, and the direction of the connecting hole is perpendicular to the height direction of the connecting column, and a connecting bolt is installed in the threaded hole.

[0014] A further technical solution of the utility model is that the inner wall of the connecting hole is provided with a thread, and the size of the thread is the same as the size of the threaded hole.

[0015] The beneficial effect is that the setting of the inner thread of the connecting hole enables the connecting bolt to fix the installation column during installation, reduces the slippage of the installation column in the installation groove, and improves the stability of the wall formed by splicing wall panels.

[0016] A further technical solution of the utility model is that a countersunk hole is opened at one end of the wallboard where the threaded hole passes through the end face of the wallboard, the size of the countersunk hole is larger than the size of the threaded hole, and the center of the countersunk hole and the threaded hole are on the same straight line.

[0026] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0027] like Figure 1-3 As shown, a connection structure of an assembled building includes a wall panel 1. In this embodiment, the wall panel 1 is a prefabricated rectangular wall panel 1 with a certain thickness; a plurality of mounting columns 2 are fixedly installed on both adjacent end surfaces of the wall panel 1, and the plurality of mounting columns 2 are evenly distributed on the end surfaces of the wall panel 1. A plurality of mounting grooves 3 are opened on the two end surfaces of the wall panel 1 opposite to the end surfaces on which the mounting columns 2 are installed. The number of the mounting grooves 3 is the same as the number of the mounting columns 2. When the wall is spliced, the mounting columns 2 are inserted into the mounting grooves 3 to connect the adjacent wall panels 1; a threaded hole 4 is opened on the wall panel 1, and the length direction of the threaded hole 4 is perpendicular to the mounting groove 3 and penetrates through the wall panel 1. The length direction of the threaded hole 4 in the mounting groove 3 passes through the end face of the wall panel 1, and the mounting column 2 is provided with a connecting hole 5, the direction of the connecting hole 5 is perpendicular to the height direction of the mounting column 2, and a connecting bolt 6 is installed in the threaded hole 4. The connecting bolt 6 passes through the threaded hole 4 and the connecting hole 5, so that the connection between the mounting column 2 and the mounting groove 3 is tighter, and the connection strength between the adjacent wall panels 1 is further improved; and by inserting the mounting column 2 in the mounting groove 3, the connecting bolt 6 passes through the mounting column 2 and the mounting groove 3, so that the splicing between the adjacent wall panels 1 becomes quick, reducing the complexity of the construction personnel in the splicing, thereby improving the construction efficiency of the spliced ​​wall panels 1.

[0028] Reference Figure 2 The size of the end of the installation groove 3 away from the end face of the wall panel 1 is smaller than the size of the end of the installation groove 3 facing the end face of the wall panel 1. The setting of the large and small heads of the installation groove 3 makes the installation of the installation column 2 faster; the size of the end of the installation column 2 away from the end face of the wall panel 1 is smaller than the size of the end of the installation column 2 facing the end face of the wall panel 1. The setting of the large and small heads of the installation column 2 makes it possible for the construction personnel to align the small head of the installation column 2 with the large head of the installation groove 3 when inserting the installation column 2 into the installation groove 3, so as to facilitate the rapid installation of the installation column 2 into the installation groove 3, thereby further improving the splicing efficiency.

[0029] Reference Figure 2 and Figure 3The mounting groove 3 includes a first mounting groove 31 and a second mounting groove 32. The first mounting groove 31 is opened in the longitudinal direction of the wall panel 1, and the second mounting groove 32 is opened in the transverse direction of the wall panel 1. The size of the first mounting groove 31 matches the size of the mounting column 2 to facilitate the fixation of the mounting column 2 after installation; the cross-section of the second mounting groove 32 is trapezoidal, and the length of the second mounting groove 32 away from the end face of the wall panel 1 is greater than the height of the mounting column 2. When the wall panel 1 is longitudinally and transversely spliced ​​with the adjacent wall panel 1, the mounting column 2 is inserted into the second mounting groove 32 and then slid toward the first mounting groove 31 so that the longitudinally installed mounting column 2 is inserted into the first mounting groove 31, thereby realizing the longitudinal and transverse splicing of the wall panel 1.

[0030] Reference Figure 2 A thread is provided on the inner wall of the connecting hole 5, and the size of the thread is the same as the size of the threaded hole 4, so that when the connecting bolt 6 is inserted into the threaded hole 4, the thread provided on the inner wall of the connecting hole 5 cooperates with the thread on the connecting bolt 6, making the connection between the mounting column 2 and the mounting groove 3 tighter.

[0031] Reference Figure 2 A countersunk hole 7 is provided at one end of the wall panel 1 where the threaded hole 4 extends out of the end face of the wall panel 1. The size of the countersunk hole 7 is larger than that of the threaded hole 4. The center of the threaded hole 4 is on the same straight line. The connecting bolt 6 is a hexagon socket bolt. The setting of the countersunk hole 7 allows the connecting bolt 6 to keep the end face of the wall panel 1 flat after installation. The use of a hexagon socket bolt for the connecting bolt 6 makes it easy to disassemble the connecting bolt 6.

[0032] Reference Figure 1 A sealing strip 8 is installed circumferentially on the wall panel 1. The sealing strip 8 is made of EPDM rubber, which has good elasticity, resistance to compression deformation, and aging resistance. The sealing strip 8 is fixedly connected to the end face of the wall panel 1 and covers the end face of the wall panel 1. When the mounting column 2 is inserted into the mounting groove 3, the end faces of the adjacent wall panels 1 squeeze the sealing strip 8. Due to its own properties, the sealing strip 8 fills the gap between the wall panels 1, thereby improving the sealing of the spliced ​​wall.

[0033] In the present invention, after the wall panel 1 is pulled from the prefabrication factory to the construction site, the construction personnel need to check the following conditions of the wall panel 1, whether the sealing strip 8 fixedly installed on the end face of the wall panel 1 is intact, whether the thread in the connection hole 5 is intact, and whether the threaded hole 4 is blocked, and then proceed to splice the wall after confirming that there is no problem; first, fix the wall panel 1 according to the preset reference on the ground, then lift the wall panel 1 by a crane for longitudinal splicing, insert the installation column 2 into the second installation groove 32 and slide the installation column 2 in the second installation groove 32 until the longitudinally spliced ​​wall panels 1 are aligned in length, and then proceed to the threaded hole 4. Install the connecting bolts 6 to strengthen the connection between the wall panels 1; after the longitudinal splicing is completed, perform the lengthwise splicing, lift the wall panel 1 by a crane, and then insert the mounting column 2 into the second mounting groove 32, so that the mounting column 2 slides in the second mounting groove 32, and then insert the mounting column 2 into the first mounting groove 31 until the mounting column 2 can no longer slide in the second mounting groove 32. At this time, the connection between the mounting column 2 and the first mounting groove 31 is completed, and the longitudinal and transverse connecting bolts 6 are concealed in the threaded holes 4 opened in the wall panel 1 to strengthen the connection between the adjacent wall panels 1; repeat the above actions to complete the splicing of the entire wall.
