Referring to fig. 2-4, the embodiment of the utility model provides an anti-leakage device for an outer wall construction joint, which comprises a tongue-and-groove piece 1 and a locking piece 2. The tongue-and-groove member 1 is used for being fixed with the outer wall outer side template 10, one side of the tongue-and-groove member 1 facing the outer wall is provided with an inclined plane 121, the inclined plane 121 is used for being matched with the top of the outer wall when the outer wall is poured so as to form an inclined tongue-and-groove on the outer wall, and the locking member 2 is used for fixing the tongue-and-groove member 1 with the outer wall outer side template 10.

Before the exterior wall is poured, the tongue-and-groove member 1 is fixed on the exterior wall outside template 10 by fixing the tongue-and-groove member 1 on the exterior wall outside template 10 by adopting the locking member 2. When the outer wall is poured, the top concrete of the outer wall can be changed in shape by the inclined plane 121 of the tongue-and-groove member 1 to form an inclined tongue-and-groove, and when another layer of outer wall (which can be called as an i-th layer shear wall 20, see fig. 1 and 4 for details) is poured on the current outer wall (which can be called as an i-1 th layer shear wall 30, see fig. 1 and 4 for details), an outer wall construction joint a between the i-th layer shear wall 20 and the i-1 th layer shear wall 30 forms a fold line shape instead of a construction joint a of a traditional horizontal shape, so that water is difficult to permeate from the construction joint a of the fold line shape, and the safety performance of the structure can be improved.

According to the anti-leakage device for the outer wall construction joint, the structure of the outer wall construction joint a is changed, so that water leakage of the outer wall construction joint can be avoided, and the safety performance of a building structure is improved.

Referring to fig. 3, further, the tongue-and-groove member 1 is provided with a fixing portion 11, the fixing portion 11 is provided with a groove 111 adapted to the top of the outer wall outside template 10, the top of the outer wall outside template 10 is clamped into the groove 111, and the locking member 2 sequentially penetrates through the fixing portion 11 and the outer wall outside template 10 to fix the tongue-and-groove member 1. In this way, the mounting structure of matching the groove 111 with the top of the outer wall outer side template 10 is adopted, so that on one hand, the mounting difficulty of the tongue-and-groove piece 1 and the outer wall outer side template 10 is reduced, and on the other hand, the connection stability of the tongue-and-groove piece 1 and the outer wall outer side template 10 can be improved.

Referring to fig. 2-3, further, the tongue-and-groove member 1 further includes a tongue-and-groove portion 12, the tongue-and-groove portion 12 is located on a side of the fixing portion 11 facing away from the outer wall outside formwork 10, the tongue-and-groove portion 12 has a triangular structure, and the inclined surface 121 is a plane of the triangular structure. Therefore, the tongue-and-groove part 12 with the triangular structure is adopted, so that on one hand, the stability of the joint of the inclined plane 121 and the outer wall of the tongue-and-groove part 1 in the construction process is ensured, and on the basis, the material utilization rate of the tongue-and-groove part 1 can be effectively improved, thereby reducing the material cost.

In this embodiment, the distance from the highest point to the lowest point of the inclined surface 121 is 15mm-35mm, specifically 20mm can be adopted, so that the inclined rabbet left on the outer wall can be ensured to be moderate, and the leakage-proof effect is not achieved even though the inclined rabbet is not narrow, and the building structure of the shear wall is not affected due to the fact that the inclined rabbet is too wide.

Further, the inclined surface 121 is provided with a U-shaped groove (not shown) for avoiding the reinforcing steel bar of the outer wall, so that the reinforcing steel bar can be avoided during construction, and the problem that the tongue-and-groove member 1 cannot be installed due to the existence of the reinforcing steel bar, and the final forming effect a is affected is avoided

Referring to fig. 2, further, the locking member 2 has a cylindrical structure, and opposite sides of the recess 111 are provided with circular holes (not shown) through which the locking member 2 passes. Therefore, the tongue-and-groove piece 1 and the outer wall outer side template 10 can be fixed only by inserting the locking piece 2 into the round hole. When in installation, the locking piece 2 can be directly inserted into the round hole to realize fixation; when the locking piece 2 is dismounted, the dismounting can be realized by directly drawing out the locking piece 2, so that the dismounting efficiency of the tongue-and-groove piece 1 is improved.

It should be noted that, the round hole on one side of the groove 111 facing the outer side of the outer wall outside template 10 is a through hole, so that the locking member 2 can penetrate through the round hole on the opposite side of the groove 111, the round hole on one side of the groove 111 facing the inner side of the outer wall outside template 10 can be a through hole or a blind hole, when the blind hole is adopted, the locking member 2 can be inserted and positioned, and the condition that the locking member 2 is inserted too deeply to leave marks on the outer wall is avoided, so that the appearance of the outer wall is affected.

Referring to fig. 2, further, one end of the locking member 2 extends out of the outer wall outside form 10, so as to facilitate rapid extraction of the locking member 2, and further improve the disassembly efficiency of the tongue-and-groove member 1.

In this embodiment, the locking member 2 may be, but not limited to, a latch.

In this embodiment, the tongue-and-groove member 1 is made of PCV material or metal material.
