Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall waterproofing, in particular to an exterior wall bolt hole sealing device. Background Art

[0002] During the construction process, when constructing the wall structure, the formwork on both sides of the reinforced concrete exterior wall is generally connected with ordinary tension screws.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] See Figure 1-Figure 7 .

[0025] In response to the problems mentioned in the above background technology, the embodiment of the present invention provides an external wall bolt hole sealing device to solve the above technical problems. The technical solution is as follows:

[0026] A device for sealing an exterior wall bolt hole includes: a sealing fixed shell 110, an expansion shell 120, a sealing body 130, and a sealing plug 140; specifically, the sealing fixed shell 110, the expansion shell 120, and the sealing plug 140 are all made of metal;

[0027] The blocking and fixing shell 110 and the expansion shell 120 are integrally formed and fixedly connected; the outer diameter of the blocking and fixing shell 110 is larger than the outer diameter of the expansion shell 120; a through channel 111 is provided on the blocking and fixing shell 110 along its axial direction;

[0028] Figure 5-Figure 6 As shown; the expansion shell 120 includes a plurality of expansion plates arranged in a circular array, with gaps between adjacent expansion plates; the expansion plates are connected to the blocking and fixing shell 110 at a point where an arc-shaped transition is made through a thin metal plate;

[0029] A plurality of expansion plates arranged in a circular array enclose a second channel 122 ; the second channel 122 is connected to the first channel 111 , and the aperture of the second channel 122 is smaller than the aperture of the first channel 111 ;

[0030] The sealing body 130 is annular and is sleeved on the outside of the expansion shell 120. Preferably, the sealing body 130 and the expansion shell 120 have the same length.

[0031] The sealing plug 140 includes an integrally formed cylindrical striking head 141 and a frustum-shaped sealing head 142; the diameter of the cylindrical striking head 141 is the same as the aperture of channel one 111, the diameter of the head 142a of the frustum-shaped sealing head 142 is smaller than the aperture of channel two 122, and the diameter of the tail 142b of the frustum-shaped sealing head 142 is larger than the aperture of channel two 122.

[0032] The working method of the external wall bolt hole sealing device provided by the embodiment of the utility model is as follows:

[0033] 1. Before plugging the bolt hole, the size of the hole plugging device needs to be specifically designed according to the size of the bolt hole in the exterior wall. Generally, the outer diameter of the plugging fixed shell 110 in the hole plugging device is equal to the diameter of the bolt hole.

[0034] 2. Figure 7 As shown; when the external wall bolt hole sealing device is performing the sealing operation, a sealing material such as a polyurethane foaming agent 200 is filled in the bolt hole in advance; then the hole sealing device is inserted into the bolt hole, and a nail is hammered into the gap between the sealing fixing shell 110 and the bolt hole to fix it, and the relative displacement between the sealing fixing shell 110 and the bolt hole is limited as much as possible;

[0035] 3. Install the sealing plug 140 according to Figure 4 The sealing plug 140 is inserted into the channel 1 111 on the fixed shell 110 in the direction shown, and the sealing plug 140 is struck with a hammer, causing the frustum-shaped sealing head 142 in the sealing plug 140 to move forward and enter the channel 2 122 of the expansion shell 120. The expansion plates arranged in a circular array expand outward under the pressure of the sealing plug 140, and the sealing body 130 is propped up outward to press against the wall of the bolt hole to seal, thereby sealing the gap between the hole sealing device and the bolt hole. At the same time, due to the expansion and compression of the sealing body 130 by the expansion plates, the outer side of the expansion shell 120 and the inner side of the sealing body 130 are also sealed.

[0036] 4. During the forward movement of the sealing plug 140, the cylindrical striking head 141 in the sealing plug 140 is stuck in the channel 111 of the sealing fixed shell 110 to seal, and the channel 111 in the hole sealing device itself is sealed and blocked; thus, the above operation completes the sealing operation of the bolt hole position.

[0037] In this embodiment, the outer wall of the sealing body 130 is provided with a plurality of ridges at intervals along the axial direction of the sealing body 130; the ridges are provided to increase the friction between the sealing body 130 and the wall of the bolt hole; the sealing body 130 and the ridges are both made of rubber; rubber is used as the material for the sealing body and the ridges mainly because of its excellent elasticity and sealing performance. Rubber can effectively resist the penetration of water, gas and chemicals, ensuring a good sealing effect; in addition, rubber has excellent wear resistance and anti-aging properties, adapts to different temperatures and environmental conditions, and ensures long-term use.

[0038] In this embodiment, a plurality of annular sealing rings 141 a are provided at intervals along the circumference of the cylindrical striking head 141 ; the annular sealing rings 141 a are provided to increase the sealing performance between the sealing plug 140 and the channel 1 111 .

[0039] In this embodiment, the expansion plate of the expansion shell 120 is provided with holes. Providing the holes on the expansion plate reduces the weight of the expansion shell 120 and reduces the production cost.

[0040] An external wall bolt hole sealing device provided by an embodiment of the utility model has the following beneficial effects: The utility model designs an external wall bolt hole sealing device, which can seal the bolt hole at the hole position of the external wall bolt hole, and can effectively prevent rainwater from penetrating into the wall through the bolt hole on the external wall, thereby improving the sealing effect.
