AI Technical Summary
In existing prefabricated building walls, bolts are prone to damage during assembly, resulting in insufficient strength.
The structure employs a combination of mating grooves and mating protrusions. Initial positioning and further fixation are achieved through the snap-fit grooves and snap-fit protrusions, followed by the pouring of concrete to enhance the overall strength.
This avoids the need for bolts and hardware for fixing, thus improving the overall strength and stability of the wall.

Description
TECHNICAL FIELD
[0001] The utility model relates to wall technology field, concretely is a wall splicing structure for prefabricated building. BACKGROUND
[0002] The building assembled by the prefabricated parts at the site is called prefabricated building, has the advantages of being able to prefabricate in advance in factory, directly assembling in construction site, reducing operation time and building speed.
[0003] The prefabricated building wall in prior art is mostly fixed by bolt and hardware when being spliced, when the bolt bears too large force, is easy to cause damage.
[0004] Therefore, a wall splicing structure for prefabricated building is provided. SUMMARY
[0005] The utility model discloses a wall splicing structure for prefabricated building to solve the problem in the above background technology.
[0006] To achieve the above object, the utility model provides the following technical scheme: a wall splicing structure for prefabricated building, including wall, the wall one side evenly installs a plurality of butt protrusions, the butt protrusion bottom is equipped with the clamping groove,
[0007] The other side of the wall is evenly provided with a butt groove, and the bottom of the butt groove is provided with a clamping protrusion.
[0008] Preferably, the length of the butt groove is greater than the sum of the lengths of the butt protrusion and the clamping protrusion.
[0009] Preferably, the clamping groove is matched with the clamping protrusion.
[0010] Preferably, the first feeding hole is formed in the butt protrusion.
[0011] Preferably, the second feeding hole is formed in the clamping protrusion.
[0012] Preferably, the first feeding hole and the second feeding hole are communicated.
[0013] Preferably, the first feeding hole, the second feeding hole and the butt groove are filled with concrete.
[0014] Compared with the prior art, the wall splicing structure has the beneficial effects that: the two walls are preliminarily positioned through the butt joint groove and the butt joint protrusion, then the position of the walls is further limited and fixed through the clamping groove and the clamping protrusion, and then the concrete is poured in the gap between the walls to enhance the overall strength, the device avoids the use of bolts and hardware for fixing, and the insufficient strength is avoided.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model.
[0021] Please refer to Figures 1-4 , the utility model provides a technical scheme: a wall splicing structure applied to fabricated building, including wall 1, the one side of wall 1 is evenly installed with multiple butt joint protrusions 2, the bottom of butt joint protrusion 2 is provided with clamping groove 5;
[0022] The other side of wall 1 is evenly provided with butt joint groove 3, and the bottom of butt joint groove 3 is provided with clamping protrusion 6.
[0023] As Figure 4 Shown: the length of butt joint groove 3 is greater than the sum of the length of butt joint protrusion 2 and clamping protrusion 6; through the above setting, after butt joint protrusion 2 is inserted into the inside of butt joint groove 3, it can be located above clamping protrusion 6, then clamping protrusion 6 and clamping groove 5 can be mutually butted together in the process that butt joint protrusion 2 moves downwards.
[0024] As Figure 2 , Figure 3 and Figure 4 Shown: clamping groove 5 is matched with clamping protrusion 6; through the above setting, clamping groove 5 and clamping protrusion 6 can limit the two walls 1 by mutual cooperation, and the case that wall 1 moves randomly is avoided.
[0025] As Figure 2 And Figure 3 As shown: the first feeding hole 4 is opened on the butt protrusion 2, the second feeding hole 7 is opened on the clamping protrusion 6, and the first feeding hole 4 and the second feeding hole 7 are communicated; through the above setting, the first feeding hole 4 and the second feeding hole 7 communicated can make the inside full of concrete when pouring concrete, and guarantee the overall strength.
[0026] As Figure 4 As shown: the first feeding hole 4, the second feeding hole 7 and the butt groove 3 are poured with concrete; through the above setting, pouring concrete ensures the overall strength.
[0027] Working principle: firstly, the two wall bodies are butted together through the butt groove 3 and the butt protrusion 2, then the wall body 1 on one side is moved downward, then the clamping groove 5 and the clamping protrusion 6 are matched together, the wall body 1 on both sides is limited, and the first feeding hole 4 and the second feeding hole 7 are aligned, then after the two wall bodies 1 are spliced, the concrete is poured in the gap between the two wall bodies 1 through the first feeding hole 4 and the second feeding hole 7, and the overall strength is increased.
[0028] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
