Construction structure for blocking shear wall bolt holes through rubber materials

Abstract

The utility model discloses a construction structure for plugging a bolt hole of a shear wall by using a rubber material. The construction structure comprises the shear wall with the bolt hole; the middle part of the bolt hole of the shear wall is filled with the micro-expansive cement mortar; the conical filling rubber cone can generate elastic deformation, and the conical filling rubber cone is arranged in the micro-expansive cement mortar. When the micro-expansive cement mortar expands or contracts in the solidification stage, the conical filling rubber cones capable of generating elastic deformation generate elastic deformation for space supplement, and the conical filling rubber cones abut against the micro-expansive cement mortar to be tightly attached to the inner wall of a bolt hole of a shear wall all the time. The problem that in the prior art, an expansive cement mortar layer cannot be tightly attached to the inner wall of a bolt hole all the time when solidified and shrunk is solved.

Description

Technical Field

[0001] The utility model relates to a construction structure for sealing shear wall bolt holes by utilizing rubber materials, and belongs to the technical field of construction. Background Art

[0002] At present, during the construction of shear walls, large bolt holes are left when fixing the concrete formwork, and the bolt holes need to be waterproofed and sealed.

[0003] The existing technology for plugging bolt holes is disclosed in Chinese Patent Publication No. CN208996452U. The disclosed technology is: an expansive cement mortar layer is filled in the middle of the bolt hole, and both ends of the expansive cement mortar layer are plugged by installing rubber plugs and sealing adhesive layers; although the bolt hole can be plugged, the expansive cement mortar layer cannot always be tightly attached to the inner wall of the bolt hole when it solidifies and shrinks. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a construction structure for sealing the bolt holes of shear walls by using rubber materials.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a construction structure for sealing shear wall bolt holes by using rubber material, comprising:

[0007] Shear walls with bolt holes;

[0008] Micro-expansion cement mortar, which is filled into the middle of the bolt hole of the shear wall;

[0009] The conical filling rubber cone can undergo elastic deformation, and the conical filling rubber cone is in the micro-expansive cement mortar.

[0010] The conical filling rubber cone is a cone-shaped body.

[0011] The conical filling rubber cone is elastic rubber.

[0012] The two ends of the conical filling rubber cone correspond to the two ends of the micro-expansion cement mortar and are flush in the bolt holes of the shear wall.

[0013] The bolt holes at both ends of the conical filling rubber cone are respectively installed with water-swellable rubber plugs A and water-swellable rubber plugs B.

[0014] The shear wall located at the water-swellable rubber plug A and the water-swellable rubber plug B is coated with a waterproof layer.

[0015] The beneficial effect of the utility model is that when the micro-expanding cement mortar expands or contracts during the solidification stage, the conical filling rubber cone that can undergo elastic deformation can elastically deform to supplement the space, and the conical filling rubber cone presses against the micro-expanding cement mortar to always adhere to the inner wall of the bolt hole of the shear wall, thereby solving the problem in the prior art that the expansive cement mortar layer cannot always adhere to the inner wall of the bolt hole when solidifying and shrinking.

[0017] In the figure: 1-conical filling rubber cone; 21-water-swelling rubber plug A; 22-water-swelling rubber plug B; 3-micro-expanding cement mortar; 4-shear wall. DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0019] like Figure 1 shown.

[0020] The present application discloses a construction structure for sealing shear wall bolt holes using rubber material, comprising:

[0021] A shear wall 4 supporting the building body has bolt holes on the shear wall 4, and the bolt holes are filled with a micro-expansive cement mortar 3; the micro-expansive cement mortar 3 is composed of anti-cracking mortar, two-component JS polymer cement-based waterproof coating, expansion agent, and cement components, and the mass ratio thereof is anti-cracking mortar: two-component JS polymer cement-based waterproof coating: expansion agent: cement = 100:10:9:1.

[0022] A conical filling rubber cone 1 capable of elastic deformation is installed in the micro-expansive cement mortar 3. The conical filling rubber cone 1 is a cone and is made of elastic rubber. The two ends of the conical filling rubber cone 1 correspond to the two ends of the micro-expansive cement mortar 3 and are flush with the bolt holes of the shear wall 4.

[0023] The bolt holes at both ends of the conical filling rubber cone 1 are respectively installed with water-swellable rubber plugs A21 and B22. The water-swellable rubber plugs A21 and B22 seal the bolt holes at both ends of the conical filling rubber cone 1.

[0024] The specific steps of construction and installation are as follows: prepare the micro-expanding cement mortar 3 according to the mass ratio, dip the conical rubber cone 1 into the micro-expanding cement mortar 3 and keep the dwelling time at 3s to 5s, and then steadily insert it into the bolt hole of the shear wall 4 after being moistened by sprinkling water, and ensure that the micro-expanding cement mortar 3 overflows after insertion; when the micro-expanding cement mortar 3 expands or contracts during the solidification stage, the conical filling rubber cone 1 that can undergo elastic deformation undergoes elastic deformation to supplement the space, and the conical filling rubber cone 1 presses against the micro-expanding cement mortar 3 to always be close to the inner wall of the bolt hole of the shear wall 4, thereby solving the problem that the expansive cement mortar layer in the prior art cannot always be close to the inner wall of the bolt hole when solidifying and shrinking.

[0025] After the conical rubber cone 1 is installed, the micro-expanding cement mortar 3 overflowing from the surface is cleaned, and water-expanding rubber plugs A21 and B22 are inserted into the two sides accordingly;

[0026] Apply twice, with the bolt hole of shear wall 4 as the center and a waterproof layer of square or circle with a radius of not less than 50mm, and the thickness of the waterproof layer is not less than 1.5mm. After the waterproof layer is applied to form a film, it should be maintained, and the maintenance process is the same as the maintenance of concrete.
