Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building construction crack reinforcement structure. Background Art

[0002] After long-term use, the bearing capacity of buildings (such as bridges, houses, etc.) will decrease due to various reasons. This is mainly manifested in cracks in the walls of old buildings (or bridges) due to settlement and other reasons. In order to reinforce the walls of buildings with cracks, crack reinforcement devices are usually used to fix the width of the cracks to reinforce the walls.

[0003] A Chinese patent application (CN217480884U) discloses a device for reinforcing cracks in construction. The device for reinforcing cracks in construction disclosed in the specification includes a reinforcing plate and an expansion bolt, wherein a plurality of winding rods are fixed equidistantly on the front side of each reinforcing plate; a clamping plate is arranged on the side of each winding rod, and a connecting sleeve rod is fixed on the side of the clamping plate, and the front end of the connecting sleeve rod is slidably connected with the front end of the winding rod, an adjusting groove is arranged inside each connecting sleeve rod, and a fixing screw is slidably sleeved inside the adjusting groove, and the rear end of each fixing screw is fixed at the center position of the front side of the winding rod, and a first pressure block is threadedly sleeved on the adjusting groove on the front side of each connecting sleeve rod, and each group of two reinforcing plates are connected front and back by an auxiliary structure, and each group of two reinforcing plates are connected on the sides by a connecting structure. The auxiliary structure includes a reinforcing support plate and a connecting screw. Each reinforcing plate on the side of the rod is rotatably connected to a reinforcing support plate. Each group of upper and lower reinforcing support plates are slidably sleeved with a connecting screw. Each reinforcing support plate is provided with a movable groove that cooperates with the connecting screw. A second pressure block is threadedly sleeved on the connecting screw on the front side of each front reinforcing support plate.

[0004] As can be seen from the above, the reinforcement plates on both sides of the crack are connected by two reinforcement support plates. However, a movable groove is provided on the reinforcement support plate in the length direction, and the connecting screw passes through the two reinforcement support plates and is threadedly connected to the second pressure block. Therefore, the two reinforcement support plates are clamped and fixed by the connecting screw and the second pressure block. However, in actual use, the two reinforcement support plates are fixed by the cooperation of the connecting screw and the second pressure block, and the reinforcement support plates do not support the connecting screw. The friction force between the two reinforcement support plates is solely relied on, which is not stable enough and the two reinforcement support plates are easily separated from each other, so that the two reinforcement plates move relative to each other, which cannot meet the reinforcement effect of the crack.

DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] See also Figure 1-4As shown, the utility model is a building construction crack reinforcement structure, including a reinforcement plate, a fixing plate 10 and a fixing assembly. The reinforcement plate includes a first reinforcement plate 1 and a second reinforcement plate 2. The first reinforcement plate 1 is provided with a connecting plate 5, and a plurality of adjustment holes 15 are provided on the connecting plate 5 at intervals along the length direction. The second reinforcement plate 2 is installed with a connecting strip 6, and the connecting strip 6 is provided with a limiting screw 11, and the limiting screw 11 is threadedly connected with a limiting nut 13; a limiting rod 14 is provided on the fixing plate 10, and a limiting screw hole 12 is provided on the fixing plate 10 corresponding to the limiting screw 11; wherein, the connecting plate 5 and the connecting strip 6 are connected through the fixing plate 10, the limiting rod 14 is movably inserted into the adjustment hole 15, and the limiting screw 11 passes through the limiting screw hole 12 and is threadedly connected with the limiting nut 13; the first reinforcement plate 1 and the second reinforcement plate 2 are fixedly installed on the building through the fixing assembly.

[0023] The fixing assembly includes a first fixing assembly 3 and a second fixing assembly 4. The first fixing assembly 3 is used to fix the first reinforcement plate 1 on the building. The second fixing assembly 4 is used to fix the second reinforcement plate 2 on the building.

[0024] It should be noted that the first reinforcement plate 1 and the second reinforcement plate 2 can be extended and installed according to the extension direction of the cracks on the building. The number of connecting plates installed on the first reinforcement plate can be 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10, etc. The number of connecting strips 6 installed on the second reinforcement plate can also be 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10, etc. During installation, the limiting rod 14 on the fixing plate 10 is inserted into the adjustment hole 15 to achieve the connection and fixation between the fixing plate and the connecting plate; the limiting screw 11 passes through the limiting screw hole 12 on the fixing plate and is threadedly connected with the limiting nut 13, and the limiting nut 13 is tightened, so that the fixing plate and the connecting strip are fixedly connected.

[0025] The number of the adjustment holes 15 can be 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10, etc. The plurality of adjustment holes are linearly spaced and distributed on the connecting plate 5. It is understandable that the connecting plate can be provided with one or two rows of adjustment holes.

[0026] like Figure 4 As shown, a limiting rod 14 adapted to the adjustment hole 15 is fixedly connected to the fixing plate 10. When the fixing plate 10 and the connecting strip 6 are fixed, the limiting rod 14 is inserted into the corresponding adjustment hole 15, so that the fixing plate 10 and the connecting plate 5 are fixed, and then the connecting plate 5 and the connecting strip 6 are fixed, so that the first reinforcement plate 1 and the second reinforcement plate 2 will not be relatively far away from or close to each other, so that the cracks in the building can be stably reinforced to ensure the reinforcement effect.

[0027] In some embodiments, a structure of a fixing assembly is provided, wherein the fixing assembly includes expansion bolts 303 . The first reinforcement plate 1 and the second reinforcement plate 2 can be fixedly installed on the building by the expansion bolts 303 .

[0028] In some embodiments, a mounting structure of expansion bolts and reinforcement plates is provided. Figure 1-4 As shown, a groove 301 is provided on the first reinforcement plate 1 and the second reinforcement plate 2, and a fixing hole 302 is provided at the bottom of the groove 301; the expansion bolt 303 includes a countersunk bolt and a nut; during installation, one end of the countersunk bolt passes through the fixing hole 302 and is threadedly connected with the nut placed in the groove 301.

[0029] It is understandable that the expansion bolt 303 also includes an expansion tube, a washer and a spring washer. When in use, the countersunk bolt is threadedly connected with a fixing hole, a washer, a spring washer and a nut.

[0030] During installation, holes matching the expansion bolts 303 are first drilled on both sides of the cracks of the building, and the end of the expansion bolt 303 with the expansion tube is inserted into the hole, and the nut, spring washer and washer are removed. Then, the first reinforcement plate and the second reinforcement plate are sleeved on the corresponding expansion bolts, and the countersunk bolts penetrate the fixing holes 302, and the washers, spring washers and nuts are threadedly connected. The nuts are tightened, and the nuts sink into the fixing holes, which can prevent the countersunk bolts and nuts from protruding from the surface of the reinforcement plates. The reinforcement plates can be firmly installed on the buildings through the expansion bolts.

[0031] In some embodiments, in order to strengthen the connection support force between the connecting plate, the connecting strip and the reinforcing plate, reinforcing ribs 17 are additionally installed. Figure 1-3 As shown, at least one reinforcing rib 17 is installed at the intersections of the connecting plate 5 and the first reinforcing plate 1 , and at the intersections of the connecting strip 6 and the second reinforcing plate 2 .

[0032] It is understandable that the number of reinforcing ribs installed at each intersection can be 1, 2 or 3. The reinforcing ribs can improve the connection strength between the connecting plate, the connecting strip and the reinforcement plate.

[0033] In some embodiments, a connection structure between a connection block and a connection strip is provided. Figure 1-3 As shown, the connecting block 8 is installed on the connecting strip 6, and the limiting screw 11 is installed on the connecting block 8; an open connecting groove 7 is opened on the top surface of the connecting plate 5 along the length direction, and an open connecting hole 9 is opened on the side; when the connecting block 8 is inserted into the connecting hole 9, the limiting screw 11 is driven to be inserted into the connecting groove 7.

[0034] A connecting groove 7 adapted to the connecting strip 6 is provided on the connecting plate 5 along the length direction, and the connecting strip 6 is movably inserted into the connecting groove 7 along the horizontal direction. A connecting block 8 is fixedly connected to one end of the connecting strip 6 away from the second reinforcing plate 2, and connecting holes 9 adapted to the connecting blocks 8 are provided on both sides along the length direction of the connecting plate 5. Through the mutual cooperation between the connecting groove 7 and the limiting screw 11, the connecting block 8 and the connecting holes 9, the connecting strip 6 and the connecting plate 5 can be guided, so that the connecting strip 6 can only move along the length direction of the connecting plate 5, thereby adjusting the distance between the first reinforcing plate 1 and the second reinforcing plate 2.

[0035] Furthermore, in this embodiment, a limiting hole 16 is formed on the connection block 8 corresponding to the adjustment hole 15 , and the limiting rod 14 passes through the adjustment hole 15 and the limiting hole 16 in sequence.

[0036] The limiting rod 14 passes through the adjustment hole 15 and the limiting hole 16 in sequence, which can increase the connection strength between the connecting plate 5, the connecting strip 6 and the fixing plate 10, making it difficult for the three to separate from each other, thereby stably reinforcing the cracks in the building.

[0037] According to the above embodiments, the usage of the utility model is:

[0038] First, the distance between the first reinforcement plate 1 and the second reinforcement plate 2 is adjusted according to the width of the building crack; during the adjustment, the connection block 8 is slid in the connection hole 9, and after the adjustment is in place, the limit hole 16 is aligned with the adjustment hole 15, and then the fixing plate 10 is placed, so that the limit screw 11 passes through the limit screw hole 12, and the limit rod 14 passes through the adjustment hole 15 and the limit hole 16. Then the limit nut 13 is screwed on to fix the distance between the first reinforcement plate 1 and the second reinforcement plate 2.

[0039] Then place the first reinforcement plate 1 and the second reinforcement plate 2 on both sides of the crack of the building, and mark the positions of the fixing holes 302 on the first reinforcement plate 1 and the second reinforcement plate 2 on the building, and then drill holes corresponding to the fixing holes 302 at the marked positions, and install expansion bolts 303 in each hole. Then install the first reinforcement plate 1 and the second reinforcement plate 2 on the corresponding expansion bolts, respectively, and the countersunk bolts of the expansion bolts 303 pass through the fixing holes 302, the washers, the spring washers and the nuts are threadedly connected, and the nuts are tightened, and the nuts sink into the fixing holes, so that the first reinforcement plate 1 and the second reinforcement plate 2 are fixedly installed on the building through the expansion bolts, and the cracks in the building can be reinforced.

[0040] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
