[0002] Precast exterior walls are exterior wall components that are prefabricated in a factory and then transported to the construction site for installation. They are an important part of prefabricated buildings and can be in the form of entire walls or precast components such as exterior wall panels.

[0003] Before the existing prefabricated exterior wall edge joint connection process, it is necessary to determine the relative position of the two walls. If the alignment angle is off, it may cause the overall wall structure to be unstable. Moreover, the alignment is completed by external device, which requires the installation of a connection structure between the walls, which is time-consuming and labor-intensive.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] The following describes, with reference to the accompanying drawings, a combined connection structure for exterior wall joint locations according to an embodiment of the present invention.

[0028] like Figures 1-2 As shown, the combined connection structure for the joint of the exterior wall in this embodiment of the utility model may include: the exterior wall 1 and the connection structure 2 are integrally formed by concrete and steel reinforcement. The exterior wall 1 is columnar and its internal structure is hollow. The hollow structure of the exterior wall 1 can play a role in heat insulation. The internal hollow structure can be filled with different materials according to the site location.

[0029] Connection structure 2 includes:

[0030] Side connecting blocks 3 are installed on both sides of the exterior wall 1. Multiple sets of mortise grooves 4 and multiple sets of mortise blocks 5 are provided on the sides of the side connecting blocks 3. The shape of the mortise blocks 5 matches the shape of the mortise grooves 4.

[0031] The side connecting blocks 3 on both sides of the exterior wall 1 are symmetrically arranged around the axis. The side connecting blocks 3 can be connected together, allowing construction workers to quickly complete the connection at the joint of the exterior wall 1 during the construction of the precast wall.

[0032] Alignment blocks 6: Four sets of alignment blocks 6 are provided on the inner wall of the hollow structure. Two sets of alignment blocks 6 are located above the inner wall of the hollow structure, and the other two sets of alignment blocks 6 are located below the inner wall of the hollow structure. The hollow structure is the hollow structure of the outer wall 1, as mentioned earlier.

[0033] The positions of the upper two groups of alignment blocks 6 are staggeredly arranged with respect to the positions of the lower two groups of alignment blocks 6. When the two outer walls 1 are butt-jointed up and down, the side edges of the alignment blocks 6 are fitted to the inner walls of the outer walls 1. With the staggeredly arranged alignment blocks 6, during the process of the up-and-down butt-joint of the outer walls 1, the outer walls 1 can achieve rapid alignment.

[0034] In an embodiment of the present utility model, as Figure 2 shown, the above-mentioned combined connection structure for the position of the outer wall joint further includes a docking plate 7. The side connection block 3 has a "C" - shaped structure, and the docking plate 7 is arranged on the inner wall of the side connection block 3, and the alignment plate and the "C" - shaped structure form a cavity.

[0035] As a possible situation, the inner wall of the outer wall 1 is a plane, and the shape of the alignment block 6 is a right - angled triangle. When the upper and lower outer walls 1 are butt - jointed, the alignment block 6 is fitted to the inner wall of the outer wall 1, so that the upper and lower outer walls 1 are aligned.

[0036] As another possible situation, the inner wall of the outer wall 1 is a first inclined plane, and the fitting surface of the alignment block 6 is a second inclined plane. The sum of the angles of the first inclined plane and the second inclined plane is 90 degrees. When the upper and lower outer walls 1 are butt - jointed, the inner wall of the outer wall 1 and the fitting block of the alignment block 6 can be inclined in, so that the upper and lower outer walls 1 are rapidly aligned.

[0037] In an embodiment of the present utility model, as Figure 4 shown, the above - mentioned combined connection structure for the position of the outer wall joint further includes two groups of hollow plates 8. The hollow plates 8 and the "C" - shaped structure form three cavities. Among them, a steel bar bundle 9 is fixed in the middle cavity. The steel bar bundle 9 can achieve the up - and - down butt - joint of the outer wall 1 and can also complete the connection of the two - side outer walls 1. The steel bar bundles 9 are tied with wires, and through the pouring of the steel bar bundle 9 in the middle cavity, the fixation between the outer walls 1 is completed.

[0038] In an embodiment of the present utility model, as Figure 3 shown, the above - mentioned combined connection structure for the position of the outer wall joint further includes a connection and fixation device 10. The connection and fixation device 10 includes a connection block 11, a bolt member and a nut. The connection block 11 is in an "L" shape. At least one group of connection grooves 12 adapted to the end of the connection block 11 is opened on the surface of the docking plate 7. A threaded hole for the bolt member to pass through is penetrated on the surface of the connection block 11. To ensure the further accuracy of the connection position of the outer wall 1, the connection and fixation device 10 is provided. The end of the connection block 11 is inserted into the inner wall of the connection groove 12, and then the two connection blocks 11 are fixed by bolts and nuts, so that the alignment plate is fitted, and the rapid positioning of the two - side outer walls 1 is completed.

[0039] In summary, when the joint of the exterior wall 1 is completed, the connection position on both sides of the exterior wall 1 can be quickly determined by the connection of the side connecting block 3. Furthermore, the connection position on both sides of the exterior wall 1 can be made more accurate by the connection fixing device 10. When the exterior wall 1 is aligned vertically, the alignment block 6 and the inner wall of the exterior wall 1 can be quickly fitted together.
