Description

Technical Field

[0001] This utility model relates to the field of wall repair technology, specifically to a structure for repairing and reinforcing brick exterior walls. Background Technology

[0002] In the field of construction, brick exterior walls refer to wall structures that use bricks as the main facade material, serving multiple functions including load-bearing, enclosure, and decoration. Over time, brick exterior walls will also suffer damage from wind and rain erosion, thus requiring repair.

[0003] The common method of repairing brick exterior walls is to first cut off the damaged part and then lay new bricks. Although the whole process is simple, the damaged wall is smaller in area than the original wall surface and is separated from the surrounding walls, resulting in a serious lack of adhesion to the concrete. The repaired bricks are not stable enough. If the wall is directly chiseled to form a rugged wall surface, it is difficult for high-altitude operations and will cause serious damage to the wall.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a structure for repairing and reinforcing building brick exterior walls. Utility Model Content

[0005] The purpose of this utility model is to provide a structure for repairing and reinforcing building brick exterior walls to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The structure for repairing and reinforcing the exterior brick wall includes a repair and reinforcement auxiliary panel. The auxiliary panel is the same shape as the exterior wall bricks but larger in area than the bricks to be repaired. One side of the auxiliary panel has a positioning groove for a supporting reinforcement mesh, inside which the mesh is placed. Suction cups are installed at the four corners of the auxiliary panel's sidewall on the same side as the mesh groove, allowing the panel to be attached to the exterior of the building wall to be repaired. Multiple through-holes are evenly distributed on the mesh groove, with mesh positioning pins inserted into each hole. On the side of the positioning pin facing the mesh, a pin cap, a conical end, and a circular pressure ring are sequentially arranged, with the conical end having a diameter larger than the mesh openings of the mesh. The circular pressure ring, with a diameter of [diameter missing], is embedded into the wall under pressure. During installation, the positioning pin is placed inside the positioning hole, and pressure is applied to the pin cap. The circular pressure ring passes through the mesh of the support reinforcement net and embeds into the wall. Then, under the limiting effect of the conical end, the support reinforcement net at the conical end is tightly adhered to the outer surface of the wall, thus stably positioning the support reinforcement net on the wall to be repaired. The distribution of the positioned support reinforcement net is as follows: the conical end is attached to the wall, while the remaining parts have a certain gap with the wall. Therefore, when pouring concrete, the bricks can be stably and fully bonded to the wall surface. This process is simple to operate, and the embedded positioning pin also provides some stability for the concrete pouring.

[0008] Compared with the prior art, the beneficial effects of this utility model are: through the pressing action of the conical end and the supporting reinforcement mesh, multi-level anchoring points are formed, which enhances the interlocking strength between the new and old bricks and the concrete.

[0009] By using modular repair and reinforcement auxiliary plates in conjunction with suction cups, rapid high-altitude positioning can be achieved, avoiding large-area excavation.

[0010] The auxiliary plate can be removed without damage after the mesh positioning pins are embedded, and the supporting reinforcement mesh is left on the wall as a permanent reinforcement layer.

[0011] The corrugated suction cup adapts to irregular wall surfaces, enhancing the stability of negative pressure adsorption. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4The structure for repairing and reinforcing the exterior brick wall includes a repair and reinforcement auxiliary plate 10. The auxiliary plate 10 is shaped like the exterior brick wall but has a larger area than the brick wall to be repaired. A support reinforcement mesh positioning groove is provided on one side of the auxiliary plate 10, and a support reinforcement mesh is placed inside the groove. Suction cups 11 are installed at the four corners of the side wall of the auxiliary plate 10 on the same side as the support reinforcement mesh groove. The suction cups 11 are used to attach the auxiliary plate 10 to the outside of the exterior wall to be repaired. Multiple through-holes 15 are evenly distributed on the support reinforcement mesh groove. A mesh positioning pin 13 is movably inserted into each through-hole 15. On the side of the mesh positioning pin 13 facing the support reinforcement mesh 16, a pin cap 14, a conical end 18, and a circular pressure ring 19 are sequentially arranged. The diameter of the conical end 18 is larger than that of the support reinforcement mesh. With a mesh diameter of 16, the circular pressure ring 19 is forcefully embedded into the wall. During installation, the mesh positioning pin 13 is placed in the positioning through hole 15, and pressure is applied to the pin cap 14. The circular pressure ring 19 passes through the mesh of the support reinforcement mesh 16 and is embedded into the wall. Then, under the limitation of the conical end 18, the support reinforcement mesh 16 at the conical end 18 is tightly attached to the outer surface of the wall, thus stably positioning the support reinforcement mesh 16 on the wall to be repaired. The distribution of the positioned support reinforcement mesh 16 is as follows: the part at the conical end 18 is attached to the wall, and the rest has a certain gap with the wall. Therefore, when pouring concrete, the bricks can be stably and fully bonded to the wall surface. This process is simple to operate, and the embedded mesh positioning pin 13 can also provide some stability for the concrete pouring.

[0022] In this embodiment of the invention, a mesh inlet / outlet 17 is provided on one side of the support reinforcement mesh groove. The support reinforcement mesh is placed in the support reinforcement mesh groove through the mesh inlet / outlet 17. A positioning groove is provided inside the side wall of the support reinforcement mesh groove. That is, the edge of the support reinforcement mesh that enters through the mesh inlet / outlet 17 is placed in the positioning groove, which can be simply positioned without affecting the rapid detachment when subjected to subsequent force.

[0023] A U-shaped hand ring 12 is installed in the middle of the side of the repair and reinforcement auxiliary plate 10 away from the wall, which facilitates manual operation.

[0024] The suction cup 11 is a corrugated rubber suction cup, which is a rubber suction cup with a corrugated (pleated) structure. It achieves the adsorption function by generating negative pressure through deformation. The edge or the whole of the suction cup 11 has a wavy pleat. When pressed, the wavy pleats unfold, increasing the internal volume and forming a stronger negative pressure (vacuum effect).

[0025] Material: Mostly silicone rubber or NBR (nitrile rubber), which combines flexibility, wear resistance and air tightness.

[0026] In one embodiment of the present invention, the diameters of the pin cap 14, the tapered end 18, and the circular pressure ring 19 on the mesh positioning pin 13 are all smaller than the positioning through hole 15. That is, after the mesh positioning pin 13 is positioned, the repair and reinforcement auxiliary plate 10 can be directly removed, and the support reinforcement mesh placed in the support reinforcement mesh groove will also be released from the support reinforcement mesh groove under the pressure of the tapered end 18.

[0027] Support and reinforcement mesh is generally made of galvanized steel wire mesh or fiberglass mesh, which has a certain degree of toughness and good extensibility, making it easy to remove from the support and reinforcement mesh groove.

[0028] The working principle of this utility model is as follows: Install auxiliary plate: Attach the repair and reinforcement auxiliary plate 10 to the area to be repaired through the hand ring 12, and press the suction cup 11 to adsorb and fix it.

[0029] Inserting the support net: Insert the support reinforcement net 16 into the support reinforcement net groove through the net inlet and outlet 17, and pre-position the edge into the positioning groove;

[0030] Install the positioning pin: Insert the mesh positioning pin 13 into the positioning through hole 15 and apply pressure to make the circular pressure ring 19 embed into the wall;

[0031] The tapered end 18 expands and supports the reinforcing mesh 16 and presses it in place to form a locally fitted and gap-distributed structure.

[0032] Remove auxiliary board: Remove the repair and reinforcement auxiliary board 10, and retain the support reinforcement mesh 16 on the wall through the mesh positioning pin 13;

[0033] Concrete pouring: Fill the gap layer with concrete and support the reinforcing mesh 16 as a strengthening skeleton to improve the overall integrity.

[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
