Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a building structure reinforcement device and method. Background Art

[0002] Building reinforcement is a branch of civil engineering. To save costs, the use of older structures and buildings is increasing, and the number of projects requiring reinforcement is increasing. To improve the overall quality of building reinforcement, it is crucial to prioritize building reinforcement design.

[0003] There are multiple ways to reinforce building structures, one of which is steel cladding. This involves attaching steel angles to the corners of columns using latex cement or epoxy resin chemical grouting, and then welding the angles together with tie plates. Under load, the angle hoops provide lateral restraint on the core concrete, increasing the concrete's axial compressive strength.

[0004] However, during the actual construction process, it was found that the use of external steel reinforcement method to reinforce column components has high requirements on the surface of column components. Once floating dust and powder appear on the surface of column components, it will directly affect the bonding performance and construction quality between the angle steel and the surface of the column components, resulting in a reduction in the reinforcement performance of the reinforcement device. Summary of the Invention

[0005] The object of the present invention is to provide a building structure reinforcement device and method, which can at least solve some of the defects in the prior art.

[0006] To achieve the above-mentioned purpose, an embodiment of the present invention provides the following technical solutions: a building structure reinforcement device, comprising a plurality of angle steel pieces, each of which encloses a reinforcement interval for the placement of the building structure, and the inner angle of each angle steel piece is arranged toward the reinforcement interval; the reinforcement device also includes a cleaning mechanism for removing dust from the surface of the building structure, the cleaning mechanism is arranged at the inner angle of the angle steel piece, there are multiple cleaning mechanisms, each of which is arranged at intervals along the length direction of the angle steel piece to form multiple cleaning layers, and each cleaning layer has at least one cleaning mechanism.

[0007] Furthermore, two adjacent angle steel pieces are connected by a connecting plate, and the cleaning mechanism is arranged on the connecting plate.

[0008] Furthermore, the cleaning mechanism includes two inclined blocks respectively arranged at both ends of the fixing plate; the distance between the inclined surfaces of the two inclined blocks gradually increases from inside the reinforcement interval to outside the reinforcement interval; in the two inclined blocks at the same angle steel piece, the inclined surfaces of the two inclined blocks are an angle space for the building structure to squeeze into; the angle steel piece has a slide groove for the two inclined blocks to slide thereon, and each of the inclined blocks has a dust removal surface that can contact the surface of the building structure.

[0009] Furthermore, a rough area is provided on the dust removal surface.

[0010] Furthermore, each of the inclined blocks is provided with a sliding block which can slide in the sliding groove.

[0011] Furthermore, the sliding groove is an L-shaped groove, and the L-shaped groove is arranged along the bending direction of the inner angle of the angle steel piece.

[0012] Furthermore, the inclined block has a convex structure that can be inserted into the U-shaped notch of the fixing plate.

[0013] Furthermore, there are multiple cleaning mechanisms and multiple fixing plates, and they are arranged in a one-to-one correspondence.

[0014] Furthermore, the side of the patch plate close to the reinforcement space is a textured surface, and the side away from the reinforcement space is a smooth surface.

[0015] The embodiment of the present invention also provides the following technical solution: a building structure reinforcement method, comprising the following steps:

[0016] S1, fitting the angle steel piece to the corner of the building structure;

[0017] S2, the cleaning mechanism on the angle steel piece removes dust from the surface of the building structure during the movement of the building structure;

[0018] S3, after the action is in place, filling the gap between the cleaning mechanism and the building structure with glue.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Cleaning mechanisms are evenly spaced on the angle steel pieces. During the installation of the angle steel pieces, the cleaning mechanisms are forced to first contact the surface of the building structure and slide relative to it, thereby clearing the bonding area between the angle steel pieces and the building structure. This ensures the subsequent bonding performance between the angle steel pieces and the building structure and improves the construction quality of the reinforcement device.

[0021] 2. By pushing the angle steel pieces to fit into the corners of the building structure, an angle space is formed between the two oblique dust removal surfaces to accommodate the corners of the columns. Then the corners are forced in between the two oblique surfaces and gradually expand, pushing the two oblique blocks to move back to back, thereby forming a relative movement between the oblique dust removal surface and the fitted column surface, rubbing the dust on the column surface, achieving the purpose of improving the cleanliness of the column bonding area, thereby enhancing the bonding performance of subsequent bonding operations.

[0022] 3. When the protrusion on the bevel block moves to the head along the L-shaped groove, the bevel block is disengaged from the inner side of the angle steel and displaced to the side of the angle steel. The dust removal surface of the bevel block is always flush with the side of the column, which can remove the obstruction when the angle steel is bonded to the column. At the same time, a gap is formed between the bevel of the bevel block and the side of the inner steel and the surface of the column. On the one hand, glue can be added between the side of the angle steel and the column in the later reinforcement stage. On the other hand, the presence of the bevel block makes the end of the gusset plate be at a distance from the bonding area of ​​the angle steel during welding. Compared with the situation of direct welding to the surface of the angle steel in the prior art, the existence of the spacing can, to a certain extent, weaken the damage to the bonding area caused by high temperature generated by the subsequent gusset plate during the welding and fixing process, thereby enhancing the performance and quality of the bonding area.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 4An embodiment of the present invention provides a building structure reinforcement device, comprising a plurality of angle steel members 1, each of which encloses a reinforcement interval 10 for placement of a building structure, and the inner angle of each angle steel member 1 is arranged toward the reinforcement interval 10; the reinforcement device also comprises a cleaning mechanism for removing dust from the surface of the building structure, the cleaning mechanism being arranged at the inner angle of the angle steel member 1. There are a plurality of cleaning mechanisms, each of which is arranged at intervals along the length direction of the angle steel member 1 to form a multi-layer cleaning layer, and each cleaning layer has at least one cleaning mechanism. Two adjacent angle steel members 1 are connected by a tie plate 3, and the cleaning mechanism is arranged on the tie plate 3. In this embodiment, a plurality of cleaning mechanisms 2 equidistantly distributed above and below are installed at the inner angle of the angle steel member 1, and the cleaning mechanism 2 is used to remove dust from the surface of the building structure, and a tie plate 3 is fixed between two connected angle steel members 1. In order to alleviate the construction quality problem of reduced bonding performance between the angle steel piece 1 and the building structure due to floating dust on the surface of the building structure, the present invention distributes cleaning mechanisms 2 at equal intervals on the angle steel piece 1. During the installation of the angle steel piece 1, the cleaning mechanism 2 is forced to first contact the surface of the building structure and slide relative to it, thereby achieving the cleaning work of the bonding area between the angle steel piece 1 and the building structure, ensuring the subsequent bonding performance between the angle steel piece 1 and the building structure, and also improving the construction quality of the reinforcement device.

[0029] As an optimization solution of the embodiment of the present invention, please refer to Figures 1 to 4 The cleaning mechanism includes two inclined blocks 21, one at each end of the gusset plate 3. The distance between the inclined surfaces of the two inclined blocks 21 gradually increases from the inside of the reinforcement section 10 to the outside of the reinforcement section 10. The inclined surfaces of the two inclined blocks 21 on the same angle steel member 1 form an angled space for the building structure to squeeze into. The angle steel member 1 has a sliding groove 213 for the two inclined blocks 21 to slide on, and each inclined block 21 has a dust removal surface 214 that can contact the surface of the building structure. The dust removal surface 214 is provided with a rough area 4. Each inclined block 21 is provided with a slider 212 that can slide in the sliding groove 213. The sliding groove 213 is an L-shaped groove, which is arranged along the bending direction of the inner angle of the angle steel member 1. The inclined block 21 has a convex structure 6 that can be inserted into the U-shaped notch 5 of the gusset plate 3. There are multiple cleaning mechanisms and a one-to-one correspondence between each gusset plate 3. The side of the patch plate 3 close to the reinforcement space is a textured surface 31 , and the side away from the reinforcement space is a smooth surface 32 .

[0030] Specifically, the two inclined blocks 21 are symmetrically distributed, with their inclined surfaces 211 close to each other. A slider 212 is fixed to the bottom end of the inclined block 21. A slide 213 is provided on the inner side of the angle steel 1, and the slider 212 cooperates with the slide 213. The inclined block 21 is arranged in a trapezoidal shape, and the slide 213 is arranged in an L-shaped groove. When the slider 212 moves from one end of the L-shaped groove to the other, the side of the inclined block 21 closest to the building structure is flush with the inner side of the angle steel 1. The number of the gusset plates 3 corresponds to the number of the cleaning mechanisms 2, and the two ends of the gusset plates 3 are respectively welded and fixed to the inclined blocks 21 on the same side of two adjacent angle steels 1. Specifically, the inclined block 21 is pre-assembled into the slide groove 213, and then the angle steel piece 1 is fitted to the corner of the building structure, such as the column A. In the two inclined blocks at the same angle steel, the surface between the two inclined blocks 21 facing the reinforcement section 10 is the dust removal surface 214, so that an angle space is formed between the two dust removal surfaces 214, which is convenient for accommodating the entry of the corner of the column A. Then, its corner edges are forcibly squeezed between the two inclined surfaces 211 and gradually expanded, thereby pushing the two inclined blocks 21 to move back to back, thereby forming a relative movement between the dust removal surface 214 of the inclined block 21 and the fitted surface of the column A, rubbing the dust on the surface of the column A, achieving the purpose of improving the cleanliness of the bonding area of ​​the column A, thereby enhancing the bonding performance of the subsequent bonding operation; and when the protrusion on the inclined block 21 moves along the L-shaped groove to the head, At this time, the bevel block 21 is disengaged from the inner side of the angle steel 1 and displaced to the side of the angle steel 1. The dust removal surface 214 of the bevel block 21 is always flush with the side of the column A, which can eliminate the obstruction when the angle steel 1 is bonded to the column A. At the same time, a gap is formed between the bevel 211 of the bevel block 21 and the side of the inner steel and the surface of the column A. On the one hand, glue can be added between the side of the angle steel 1 and the column A in the later stage of reinforcement. On the other hand, the presence of the bevel block 21 makes the end of the gusset plate 3 have a distance from the bonding area of ​​the angle steel 1 during welding. Compared with the situation of directly welding to the surface of the angle steel 1 in the prior art, the existence of the distance can, to a certain extent, weaken the damage to the bonding area caused by the high temperature generated by the subsequent gusset plate 3 during the welding and fixing process, thereby enhancing the performance and quality of the bonding area. The dust removal surface 214 of the bevel block 21 is set as a rough area 4 to rub the surface of the building structure. The present invention sets the surface of the inclined block 21 that contacts the side of the column A as a rough area 4, so that when the inclined block 21 is passively displaced, a stronger scraping effect can be formed, thereby enhancing the cleaning effect of the inclined block 21 on the surface of the building structure during its movement, and further removing the floating layer, thereby reducing the bonding performance problems caused by the floating layer during bonding. Furthermore, one side of the gusset plate 3 is set as a textured surface 31, and the other side is set as a smooth surface 32. The different sides of the gusset plate 3 can easily distinguish the installation surface and speed up the assembly and welding efficiency; and the textured surface 31 is fitted with the surface of the column A, so that the surface roughness and the surface of the column A have a relatively larger active area during bonding, and the bonding effect is better.A U-shaped notch 5 is provided on the straight side surface of the inclined block 21, and the end surface of the gusset plate 3 is configured as a convex structure 6 that matches the U-shaped notch 5. The provision of the U-shaped notch 5 and the convex structure 6 in the present invention takes into account both the convenience of assembling the gusset plate 3 and the need to prevent the effects of welding heat on the bonding area. Specifically, the convex structure 6 on the end surface of the gusset plate 3 is inserted into the matching U-shaped notch 5, and the end surface of the inclined block 21 forms a covering for the convex structure 6. The coordination of the concave and convex structures makes assembly of the gusset plate 3 more convenient, the welding position more prominent, and welding more convenient. Convenient welding can shorten the welding time, and the release time of welding heat is also shortened, thereby further reducing the thermal impact on the bonding area.

[0031] See also Figures 1 to 4 An embodiment of the present invention provides a building structure reinforcement method using the aforementioned building structure reinforcement device. The method comprises the following steps: S1, attaching an angle steel member 1 to a corner of a building structure; S2, removing dust from the surface of the building structure while the cleaning mechanism on the angle steel member 1 is in motion; S3, after the cleaning mechanism has been fully activated, filling the gap between the cleaning mechanism and the building structure with glue. Specifically, the inclined block 21 is pre-assembled into the slide groove 213, and then the angle steel piece 1 is fitted to the corner of the building structure, such as the column A. In the two inclined blocks at the same angle steel, the surface between the two inclined blocks 21 facing the reinforcement section 10 is the dust removal surface 214, so that an angle space is formed between the two dust removal surfaces 214, which is convenient for accommodating the entry of the corner of the column A. Then, its corner edges are forcibly squeezed between the two inclined surfaces 211 and gradually expanded, thereby pushing the two inclined blocks 21 to move back to back, thereby forming a relative movement between the dust removal surface 214 of the inclined block 21 and the fitted surface of the column A, rubbing the dust on the surface of the column A, achieving the purpose of improving the cleanliness of the bonding area of ​​the column A, thereby enhancing the bonding performance of the subsequent bonding operation; and when the protrusion on the inclined block 21 moves along the L-shaped groove to the head, At this time, the bevel block 21 is disengaged from the inner side of the angle steel member 1 and moved to the side of the angle steel member 1. The dust removal surface 214 of the bevel block 21 is always flush with the side of the column A, which can remove the obstruction when the angle steel member 1 is bonded to the column A. At the same time, a gap is formed between the bevel 211 of the bevel block 21 and the side of the inner steel member and the surface of the column A. On the one hand, glue can be added between the side of the angle steel member 1 and the column A in the later reinforcement stage. On the other hand, the presence of the bevel block 21 makes the end of the gusset plate 3 have a distance from the bonding area of ​​the angle steel member 1 during welding. Compared with the situation of directly welding to the surface of the angle steel member 1 in the prior art, the existence of the spacing can, to a certain extent, weaken the damage to the bonding area caused by high temperature generated by the subsequent gusset plate 3 during the welding and fixing process, thereby enhancing the performance and quality of the bonding area.
