Abstract
Description
Technical Field
[0001] The invention relates to the technical field of construction tools, in particular to a hole sealing component for tension bolts in a wall. Background Art
[0002] In the construction of cast-in-place concrete shear walls, tension bolts are commonly used as key reinforcement components to ensure the stability of the formwork system during concrete pouring and prevent deformation due to expansion. Tension bolts are installed and tightened between the opposing formwork to provide lateral restraint during pouring. Once the concrete reaches the desired strength, the tension bolts are removed as a whole, and the formwork on both sides is dismantled, leaving through holes in the wall along the bolt path. To avoid compromising the structural integrity and waterproofing performance of the shear wall, the tension bolt holes left in the wall after construction need to be sealed. After cleaning the holes, they are densely filled with a specific waterproof mortar (such as cement-based waterproof mortar, polymer cement waterproof mortar, etc.), and the wall surface is smoothed to achieve the fundamental purpose of sealing and stopping water.
[0003] Currently, cement cones are commonly used to seal tension bolt holes. Specifically, a specially prepared cement cone is coated with a certain thickness of waterproof mortar and then inserted into a specific location in the hole. During this sealing process, the waterproof mortar on the surface of the cement cone can overflow from the hole, causing waste and staining the wall surface, potentially reducing the tightness of the waterproof mortar filling in the hole.

[0030] like Figures 1 to 8As shown, an embodiment of the present invention provides a wall tension bolt hole sealing assembly, including a cement cone 100 and an end cap 201. The cement cone 100 has a first end and a second end. The diameter of the cement cone 100 gradually decreases from the first end to the second end. The end cap 201 is arranged at the first end. A spiral groove 202 is formed on the outer surface of the cement cone 100. A through hole 102 is formed inside the wall 101. A first connecting member 203 is provided at the second end. A second connecting member 204 is provided on the inner side of the hole 102 near the wall 101. An exhaust hole 205 is opened on the second connecting member 204. The cement cone 100 with waterproof mortar adhered thereto is inserted into the wall. The outer side of 101 is gradually inserted into the hole 102 until the first end is located in the hole 102 near the outer side of the wall 101, and the second end is located in the hole 102 near the inner side of the wall 101; when the cement cone 100 rotates in the first rotation direction, the spiral groove 202 transports the waterproof mortar to the inner side near the wall 101; when the cement cone 100 rotates in the second rotation direction, the spiral groove 202 transports the waterproof mortar to the outer side near the wall 101, and connects the first connecting piece 203 with the second connecting piece 204, and the end cover 201 is in contact with the outer side of the wall 101. The first rotation direction and the second rotation direction are both circumferential directions of the cement cone 100 and opposite to each other.
[0031] A certain thickness of waterproof mortar is adhered to the surface of the cement cone 100, and the cement cone 100 is gradually inserted into the hole 102 from the outside of the wall 101. The air in the hole 102 is gradually discharged through the exhaust hole 205. When the waterproof mortar is observed to overflow, the cement cone 100 is rotated in the first direction, and the spiral groove 202 transports the waterproof mortar to the inner side of the wall 101, preventing the waterproof mortar from moving to the outside of the wall 101 and causing overflow, thereby avoiding waste and staining the wall surface; and then the cement cone 100 is rotated in the second direction. The cement cone 100 is rotated, and the spiral groove 202 transports the waterproof mortar to the outside of the wall 101 to fill the entire hole 102. At the same time, the first connecting piece 203 is connected to the second connecting piece 204 to insert the cement cone 100 more tightly into the hole 102. The waterproof mortar is sealed in the hole 102 through the end cover 201 on the outside of the wall 101 and the second connecting piece 204 on the inside of the wall 101, thereby ensuring that the waterproof mortar in the hole 102 is filled tightly.
[0032] The vent holes 205 have a relatively small diameter. When the waterproof mortar enters the hole 102 but does not contact the second connector 204, the vent holes 205 are used to discharge gas from the hole 102. After the waterproof mortar contacts the second connector 204, a small amount of the waterproof mortar enters and remains in the vent holes 205 due to its viscosity, thereby effectively blocking the vent holes 205 and preventing the waterproof mortar from further flowing from the vent holes 205 to the inside of the wall 101. Multiple vent holes 205 may be provided.
[0033] In the process of inserting the cement cone 100 into the hole 102 from the outside of the wall 101, the spiral groove 202 can push and stir the waterproof mortar to make the texture of the waterproof mortar more uniform.
[0034] Before inserting the cement cone 100 more tightly into the hole 102, the cement cone 100 is directly inserted into the hole 102 without adhering waterproof mortar to its surface. The cement cone 100 is then rotated in a first rotational direction, and the spiral groove 202 can transport debris remaining in the hole 102 to the outside of the wall 101. Of course, after directly inserting the cement cone 100 into the hole 102, the first end of the cement cone 100 can be lifted upward, the second end can be tilted downward, and this position can be maintained while pulling the end cap 201 and the cement cone 100. This can also remove debris remaining in the hole 102 to the outside of the wall 101, thereby pre-cleaning the hole 102.
[0035] A connecting rod 206 is fixed to the end of the first connecting member 203 near the outside of the wall 101. The connecting rod 206 is secured to the end cap 201. The cement cone 100 can be cast and molded outside the connecting rod 206, securing the cement cone 100 to the end cap 201, the connecting rod 206, and the first connecting member 203. The end cap 201, the connecting rod 206, the first connecting member 203, and the second connecting member 204 can all be made of metal to enhance the tightness and stability of the cement cone 100 when inserted into the hole 102. Furthermore, the closer the spiral groove 202 is to the outside of the wall 101, the closer its edge dimensions are to the diameter of the hole 102. As the cement cone 100 is gradually inserted from the outside of the wall 101 into the hole 102, the cement cone 100 itself can provide a certain sealing effect on the hole 102.
[0036] In one embodiment, the first connecting member 203 is a bolt, and the second connecting member 204 is a nut with an open end and a closed end respectively. The open end of the second connecting member 204 faces the first connecting member 203, and the exhaust hole 205 is opened at the closed end of the second connecting member 204.
[0037] First, the cement cone 100 is rotated in a first rotation direction, and the spiral groove 202 is used to transport the waterproof mortar toward the inner side of the hole 102 near the wall 101 until the first connecting piece 203 abuts the second connecting piece 204. Then, the cement cone 100 is rotated in a second rotation direction, and the spiral groove 202 transports the waterproof mortar toward the outer side of the wall 101. At the same time, the first connecting piece 203 is screwed into the second connecting piece 204, so that the cement cone 100 is inserted more tightly into the hole 102. Therefore, the above actions are successively achieved by rotating the cement cone 100 forward and backward, thereby more tightly inserting the cement cone 100 into a specific position of the hole 102. No other operations are required, that is, there is no need to press hard or hit the cement cone 100 with a hammer, which is convenient to operate.
[0038] The diameter of the first connecting member 203 is less than or equal to the diameter of the second end of the cement cone 100. Optionally, the threads of the first connecting member 203 and the second connecting member 204 that cooperate with each other may be tapered, such as Figure 3 In the figure, the external thread of the first connecting member 203 gradually decreases from left to right, and the internal thread of the second connecting member 204 gradually decreases from left to right.
[0039] In one embodiment, see Figure 5 A first notch 207 is formed on the outer surface of the first connecting member 203 , and the first notch 207 is arranged along the axial direction of the cement cone 100 .
[0040] During the process of inserting the cement cone 100 from the outside of the wall 101 into the hole 102, the air in the hole 102 is gradually discharged from the exhaust hole 205, and part of the waterproof mortar enters the second connecting piece 204, thereby preventing external air from entering the hole 102 through the exhaust hole 205; during the process of rotating the cement cone 100 in the second rotation direction and transporting the waterproof mortar toward the outside of the wall 101 by the spiral groove 202, the first connecting piece 203 and the second connecting piece 204 are gradually connected, and the waterproof mortar in the second connecting piece 204 is squeezed out of the first notch 207 by the first connecting piece 203. At the same time, the waterproof mortar near the first notch 207 in the hole 102 is transported toward the outside of the wall 101, which generates a suction effect on the waterproof mortar in the second connecting piece 204, thereby causing the waterproof mortar in the second connecting piece 204 to re-enter the hole 102.
[0041] The cement cone 100 is rotated in the second rotation direction, and the spiral groove 202 transports the waterproof mortar to the outside close to the wall 101. At the same time, the cement cone 100 moves toward the inside close to the wall 101 to squeeze the waterproof mortar to the outside close to the wall 101.
[0042] Multiple first notches 207 can be provided at equal intervals along the circumference of the cement cone 100. A plane parallel to the axis of the cement cone 100 is referred to as a first plane. The distance between the first plane and the axis of the cement cone 100 is less than the radius of the first connector 203. The first notches 207 are formed by sectioning the first connector 203 along the first plane. After sectioning, the first connector 203 can still be threadedly connected to the second connector 204.
[0043] In one embodiment, the end cap 201 is capable of deforming in the axial direction of the cement cone 100, and has a first state and a second state before and after the deformation. In the first state, the open ends of the first connecting member 203 and the second connecting member 204 abut against each other, and in the second state, the first connecting member 203 and the second connecting member 204 are connected.
[0044] The cement cone 100 is rotated in the first direction, and the end cover 201 is in the first state. Figure 3 , i.e., the undeformed state, until the open ends of the first connecting member 203 and the second connecting member 204 abut against each other, and the end cap 201 fits against the outer side of the wall 101 to seal the hole 102; then the cement cone 100 is rotated in the second direction, and the end cap 201 gradually deforms from the first state to the second state, see Figure 6 During this process, the end cover 201 always fits against the outside of the wall 101 to keep the hole 102 sealed, preventing the spiral groove 202 from overflowing when transporting the waterproof mortar to the outside of the wall 101.
[0045] The end cap 201 is cap-shaped and has a bottom wall and side walls. The first end of the cement cone 100 is fixed to the center of the bottom wall of the end cap 201. The side wall of the end cap 201 can deform in the axial direction of the cement cone 100 and has a tendency to return to its original shape. Furthermore, the diameter of the end cap 201 remains unchanged before and after the axial deformation of the cement cone 100.
[0046] In one embodiment, see Figure 6 A sink groove 208 is provided on the outer side of the wall 101 . When the end cover 201 is in contact with the outer side of the wall 101 , the end cover 201 is in contact with the bottom of the sink groove 208 .
[0047] The height of the trough 208 is equal to the thickness of the end cap 201. After the cement cone 100 is more tightly inserted into the hole 102, the end cap 201 fits with the bottom of the trough 208, and the end cap 201 is flush with the surface of the wall 101, which is more beautiful.
[0048] In one embodiment, see Figure 5 The end cover 201 and the sink 208 are both circular in shape and are coaxially arranged with the cement cone 100. The edge of the end cover 201 is provided with a plurality of second notches 209 at equal intervals along its circumference.
[0049] Insert a finger into the second notch 209 to rotate the end cap 201 , thereby driving the cement cone 100 to rotate. Of course, a tool that cooperates with the second notch 209 can also be provided to facilitate the rotation of the end cap 201 .
[0050] In one embodiment, the length direction of the second notch 209 is arranged at an angle to the radial direction of the end cover 201 , and the edge of the end cover 201 is made of elastic material.
[0051] The portion of the end cap 201 between the two second notches 209 forms a rotary vane 210. The diameter of the end cap 201 is the same as that of the sink 208. When the end cap 201 is in contact with the bottom of the sink 208, the edge of the rotary vane 210 abuts against the edge of the sink 208. Under normal conditions, each rotary vane 210 maintains a constant tilt angle. Rotating in the direction of the rotary vane 210 allows the end cap 201 to rotate, while rotating against the direction of the rotary vane 210 prevents the end cap 201 from rotating. This acts as a ratchet, limiting the rotational direction of the end cap 201. Specifically, when the end cap 201 is in contact with the bottom of the sink 208, the end cap 201 can only rotate in the second rotational direction, not the first rotational direction, to prevent erroneous operation.
[0052] In one embodiment, see Figure 5 The outer surface of the second connecting member 204 is provided with a plurality of spring clips 211 at equal intervals along the circumference of the cement cone 100. The spring clips 211 include an integrally formed first section 212 and a second section 213. The first section 212 is fixed to the second connecting member 204 along the axial direction of the cement cone 100. The second section 213 is arranged along the radial direction of the cement cone 100 and can elastically swing around the first section 212. The second section 213 has a third state and a fourth state before and after the swing. When the second section 213 is in the third state, the second section 213 is in contact with the first section 212. When the second section 213 is in the fourth state, the second section 213 is arranged at an angle to the first section 212, and the second section 213 tends to be in the fourth state.
[0053] During installation, the second connector 204 is pushed from the outside of the wall 101 into the hole 102. During this process, the second section 213 is in the third state, that is, the second section 213 is restricted by the hole 102 and abuts against the first section 212. Until a portion of the second connector 204 is outside the hole 102, the second section 213 swings to the fourth state under the action of its own elasticity, and the second section 213 abuts against the inside of the wall 101, thereby restricting the second connector 204 from moving along the hole 102 toward the outside of the wall 101. Of course, when convenient, the second connector 204 can also be pushed directly from the inside of the wall 101 into the hole 102, so that the second section 213 abuts against the inside of the wall 101.
[0054] The spring piece 211 is made of elastic material, such as metal.
[0055] As a structural variant, see Figure 8 The outer surface of the second connecting member 204 is provided with a plurality of inverted teeth 214 at equal intervals along the circumference of the cement cone 100. The inverted teeth 214 are used to limit the second connecting member 204 from moving along the hole 102 toward the outside of the wall 101. During installation, the second connecting member 204 can only be pushed into the hole 102 from the outside of the wall 101.
[0056] The inverted teeth 214 are arranged obliquely from the outside of the wall 101 to the inside of the wall 101 and from the outside to the inside of the second connecting member 204. Figure 8 In the embodiment, the outer end of the inverted tooth 214 is tilted to the left. The outer surface of the second connecting member 204 can be sleeved with a mounting ring 215, and the inverted tooth 214 is arranged on the mounting ring 215.
[0057] In one embodiment, a plurality of inverted teeth 214 are arranged at equal intervals along the axial direction of the cement cone 100 to enhance the restraining capability of the second connecting member 204 .
[0058] When using the present invention, after removing the tension bolts and removing the formwork, first, without allowing the waterproof mortar to adhere to the surface of the cement cone 100, insert a finger into the second notch 209 to control the movement of the end cap 201 and the cement cone 100. The cement cone 100 is directly inserted into the hole 102 and rotated in the first direction. The spiral groove 202 can transport debris remaining in the hole 102 to the outside of the wall 101. Of course, after directly inserting the cement cone 100 into the hole 102, the first end of the cement cone 100 can be lifted upward, the second end can be tilted downward, and the end cap 201 and the cement cone 100 can be pulled to remove debris remaining in the hole 102 to the outside of the wall 101, thereby pre-cleaning the hole 102.
[0059] A certain thickness of waterproof mortar is adhered to the surface of the cement cone 100, and the cement cone 100 is gradually inserted into the hole 102 from the outside of the wall 101. Figure 6 As shown, the air in the hole 102 is gradually discharged from the exhaust hole 205; when it is observed that the waterproof mortar is about to overflow, the end cover 201 and the cement cone 100 are rotated in the first rotation direction, and the spiral groove 202 transports the waterproof mortar to the inner side close to the wall 101, preventing the waterproof mortar from moving to the outer side close to the wall 101 and causing overflow, thereby avoiding waste and staining the wall surface, until the open ends of the first connecting member 203 and the second connecting member 204 abut against each other, as shown in FIG. Figure 3 As shown; the cement cone 100 is rotated in the second rotation direction, and the spiral groove 202 transports the waterproof mortar to the outside close to the wall 101 to fill the entire hole 102. The end cover 201 is fitted with the bottom of the sink 208 to seal the hole 102 to prevent the waterproof mortar from overflowing. At the same time, the first connecting piece 203 is screwed into the second connecting piece 204 to insert the cement cone 100 more tightly into the hole 102, and the waterproof mortar is sealed in the hole 102 through the end cover 201 on the outside of the wall 101 and the second connecting piece 204 on the inside of the wall 101, thereby ensuring the waterproof mortar in the hole 102 is filled tightly, as shown Figure 7 shown.
[0060] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
