Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall construction, in particular to an exterior wall screw hole plugging device. Background Technique

[0002] At present, a large number of wall-through screws are used in the construction of the exterior walls of shear walls and frame structures. The plugging of wall-through screw holes involves the risk of exterior wall leakage. In cases of exterior wall leakage, a large part of them are caused by the imperfect plugging of screw holes.

[0003] Traditional plugging of exterior wall screw holes mainly involves punching out PVC pipes and cleaning them thoroughly; first filling the interior wall with cement mortar; filling the expansion cement mortar from the outside to the inside, inserting it solidly with a steel bar, leveling the surface, and then applying a cement-based waterproof coating. This method has poor operability, the insertion depth of the cement mortar cannot be controlled, and the sealing performance does not meet the requirements. Content of the Utility Model

[0004] The purpose of the utility model is to provide an exterior wall screw hole plugging device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An exterior wall screw hole plugging device includes a plugging member. A number of anti-detachment structures are rotatably sleeved on the side surface of the plugging member. The plugging member is inserted and installed inside the screw hole structure. The plugging member includes a connecting rod. A spacing rubber ring is fixedly sleeved in the middle of the side surface of the connecting rod. An opening plugging end is fixedly installed at one end of the connecting rod. A grouting channel is penetrated and opened inside the connecting rod and the opening plugging end. An slurry outlet is penetrated and opened on the side surface of the grouting channel. A grouting interface is opened at one end of the grouting channel. A sealing plug is clamped at the grouting interface.

[0007] Furthermore: The number of the connecting rods is two. A screw sleeve is fixedly installed at one end of one connecting rod. A threaded end is fixedly installed at one end of the other connecting rod. The two connecting rods are connected by screwing the screw sleeve and the threaded end together. A pipe sleeve sliding groove is opened on the side surface of the connecting rod.

[0008] Furthermore: An inner groove is opened at the conical surface of the opening plugging end. A compensation rubber ring is fixedly sleeved at the edge of the opening plugging end.

[0009] Furthermore, the anti-slip structure includes a rotating tube sleeve, a base ring is fixedly sleeved on the edge of one end of the outer wall of the rotating tube sleeve, a claw is hinged at an equal angle in a ring shape on the edge of the base ring, the inner surface of the claw is hinged to one end of the support rod, a slider is hinged to the other end of the support rod, a sliding groove is opened on the outer wall of the rotating tube sleeve at an equal angle in a ring shape, the slider and the sliding groove are slidably engaged with each other, and a return spring is engaged inside the sliding groove.

[0010] Furthermore, the screw hole structure includes a wall, and through holes are interspersed on both sides of the wall.

[0011] Furthermore, the rotating pipe sleeve is rotatably sleeved on the pipe sleeve sliding groove.

[0012] Furthermore, the two connecting rods are inserted and installed in the through hole, the opening blocking end and the openings at both ends of the through hole are abutted against each other, and the outer surface of the opening blocking end is coated with waterproof sealing glue.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Open the sealing plug to expose the grouting interface, insert the grouting equipment into the grouting interface, inject the sealing material into the grouting channel, and fill the internal gap of the screw hole structure from the slurry outlet. The internal space of the screw hole structure is divided into multiple sections by the spacer rubber ring. First, each spacer rubber ring provides multi-layer sealing inside the screw hole structure for sealing and waterproofing. Second, the solidified sealing material is divided into multiple blocks to achieve the effect of risk separation. When a sealing block has a gap, damage, or defects in the filler, other blocks can continue to maintain the sealing and waterproofing effect, greatly improving the sealing quality and service life.

[0015] 2. In some special screw holes, for example, when the screw hole is seriously damaged by the extraction of the screw, a more expensive plugging piece with an anti-slip structure can be selected. During reverse rotation, the reverse trend causes the tips of the expanded claws to press against the inner wall of the through hole, and the pushing structure of each claw is relatively independent and can adapt to the irregular inner wall of the through hole. First, it cooperates with the spacer rubber ring to provide auxiliary support for the plugging piece, and second, it serves as the internal skeleton of the solidified plugging material to balance the strength of the irregular solidified plugging material block to avoid inconsistent strength of the irregular material block and affect the plugging effect.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, an external wall screw hole plugging device includes a plugging member 1. A plurality of groups of anti-disengagement structures 2 are rotatably sleeved on the side surface of the plugging member 1. The plugging member 1 is inserted and installed inside the screw hole structure 3. The plugging member 1 includes a connecting rod 101. A spacing rubber ring 104 is fixedly sleeved in the middle of the side surface of the connecting rod 101. One end of the connecting rod 101 is fixedly installed with an open plugging end 106. A grouting channel 109 is formed by inserting through the connecting rod 101 and the open plugging end 106. A grout outlet 110 is formed by inserting through the side surface of the grouting channel 109. A grouting interface 111 is formed at one end of the grouting channel 109. A sealing plug 112 is clamped at the grouting interface 111.

[0023] Specifically, open the sealing plug 112 to expose the grouting interface 111. Insert the grouting equipment into the grouting interface 111, inject the plugging material into the interior of the grouting channel 109, and fill the internal voids of the screw hole structure 3 from the slurry outlet 110. The internal space of the screw hole structure 3 is divided into multiple segments by the spacer rubber rings 104. Firstly, multiple layers of sealing are provided inside the screw hole structure 3 by each spacer rubber ring 104 for waterproof sealing. Secondly, the solidified plugging material is divided into multiple segments, achieving the effect of risk separation.

[0024] Embodiment 1

[0025] As Figures 1 - 3 shown, in this embodiment, the number of connecting rods 101 is two. One end of one connecting rod 101 is fixedly installed with a screw sleeve 102, and one end of the other connecting rod 101 is fixedly installed with a threaded end 103. The two connecting rods 101 are connected by screwing the screw sleeve 102 and the threaded end 103 together; the screw hole structure 3 includes a wall body 301, and through holes 302 are formed by inserting through the two sides of the wall body 301.

[0026] In this embodiment, insert the two connecting rods 101 into the through holes 302 from both ends respectively, use the card slot at the grouting interface 111 as the force application basis, rotate the two connecting rods 101 relatively, so that the screw sleeve 102 and the threaded end 103 are screwed together for connection, and stuff the open end plug 106 at the two openings on both sides of the through hole 302 for installation.

[0027] As Figures 1 - 3 shown, in this embodiment, an inner groove 107 is formed on the conical surface of the open end plug 106, and a compensation rubber ring 108 is fixedly sleeved on the edge of the open end plug 106; the two connecting rods 101 are inserted and installed in the through hole 302, the open end plug 106 abuts against the two openings at both ends of the through hole 302, and a waterproof sealant 303 is coated on the outer surface of the open end plug 106.

[0028] In the specific implementation, before grouting, the two connecting rods 101 are slightly rotated in the opposite direction so that the two connecting rods 101 tend to protrude from the openings on both sides of the through hole 302, and this tendency is used to make the side surface of the arched spacer rubber ring 104 fit more closely with the inner wall of the through hole 302, and at the same time, a certain gap is left between the fitting surface of the opening sealing end 106 and the opening of the through hole 302, and the compensating rubber ring 108 and the spacer rubber ring 104 are used to temporarily assist in supporting the sealing member 1, and grouting is performed, and the sealing material is filled into the internal space of the through hole 302, and the gap between the opening sealing end 106 and the opening of the through hole 302 is filled, and an inner concave structure is formed at the inner groove 107 to strengthen the connection tightness between the opening of the through hole 302 and the opening sealing end 106. After filling, a waterproof sealing glue 303 with a thickness equal to that of the surface of the wall 301 is applied to the exposed surface of the opening sealing end 106, and finally the surface of the wall 301 and the waterproof sealing glue 303 are painted and decorated normally.

[0029] Embodiment 2

[0030] On the basis of Example 1, in order to compensate for the fact that the plugging member 1 proposed in Example 1 is used to deal with some special screw holes that are damaged, the injected plugging material is molded into irregular plugging material blocks by the special screw holes, and its mechanical strength is uneven in different places, affecting the plugging effect.

[0031] like Figures 1 - 4 As shown, in this embodiment, a sleeve groove 105 is provided on the side surface of the connecting rod 101; the anti-slip structure 2 includes a rotating sleeve 201, and a base ring 202 is fixedly sleeved on the edge of one end of the outer wall of the rotating sleeve 201, and a claw 203 is hingedly connected to the edge of the base ring 202 in a circular shape with equal angles, and the inner surface of the claw 203 is hinged to one end of the support rod 204, and a slider 205 is hinged to the other end of the support rod 204, and a slide groove 206 is provided on the outer wall of the rotating sleeve 201 in a circular shape with equal angles, and the slider 205 and the slide groove 206 are slidably engaged with each other, and a return spring 207 is engaged inside the slide groove 206; the rotating sleeve 201 is rotatably sleeved on the sleeve groove 105.

[0032] During specific implementation, in some special screw holes, for example, when the screw hole is seriously damaged by the extraction of the screw, a more costly sealing member 1 with an anti-slip structure 2 may be selected. During reverse rotation, the tip of each expanded claw 203 is pressed against the inner wall of the through hole 302 through the reverse trend, and the pushing structure of each claw 203 is relatively independent and can adapt to the irregular inner wall of the through hole 302. Firstly, it cooperates with the spacer rubber ring 104 to provide auxiliary support for the sealing member 1, and secondly, it serves as the internal skeleton of the solidified sealing material to balance the strength of the irregular solidified sealing material blocks, so as to avoid inconsistent strength of the irregular material blocks and affect the sealing effect.
