Abstract
Description
Technical Field
[0001] This invention belongs to the field of building construction technology, and specifically relates to a reinforcement device and method for cracks in building construction. Background Technology
[0002] During the long-term use of buildings, various factors can lead to a decrease in their load-bearing capacity and the gradual formation of cracks. These cracks deepen over time, threatening the structural strength of the building and posing safety hazards. Traditional crack reinforcement methods mainly involve cleaning the cracks and then filling them with specific repair materials. Although this method can improve the crack problem to some extent, the repair effect is poor. Over time, even if the walls at both ends shift slightly, fine gaps will still form between the repair material and the walls on both sides. Therefore, we propose a reinforcement device and method for cracks in building construction to solve the above problems. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides a reinforcement device and method for cracks in building construction, which solves the problem of poor repair effect of traditional crack reinforcement methods.
[0004] This invention is achieved through the following solution: a reinforcement device for cracks in building construction, comprising: Two frames are used to fix the crack to the wall on both sides. Two fixed shaft groups are fixed on two frames respectively. Each fixed shaft group includes multiple fixed shafts, and the multiple fixed shafts are spaced apart along the height direction of the corresponding frame. The tightening rope, crisscrossed and wound around multiple fixed shafts in two fixed shaft groups, is used to continuously apply opposing preload to the two frames; and An adhesive is formed by pouring repair material into the crack and allowing it to cure, and the formed adhesive is anchored to the walls on both sides.
[0005] A further improvement of the reinforcement device for building construction cracks of the present invention is that the two frames are arranged opposite to each other, and a pouring cavity for pouring repair material into the crack is formed between the two frames.
[0006] A further improvement of the reinforcement device for building construction cracks of the present invention is that the reinforcement device further includes two templates, which are respectively connected to opposite sides of two frames, and each of the two templates has a notch at the end away from the corresponding frame. When the two frames are fixed to the walls on both sides of the crack, the two templates are attached to each other so that the two gaps are combined to form the pouring cavity that communicates with the crack and covers the crack in the wall, and a pouring port is formed at the upper end of the pouring cavity.
[0007] A further improvement of the reinforcement device for building construction cracks of the present invention is that the reinforcement device further includes a reinforcement body, which is formed by pouring repair material into the casting cavity and then curing it. The reinforcement body, the adhesive body, the walls on both sides of the crack, and the two templates are anchored into a whole.
[0008] A further improvement of the reinforcement device for building construction cracks of the present invention is that the reinforcement device further includes a seepage-proof structure set on two templates to prevent leakage of the pouring cavity at the joint of the two templates.
[0009] A further improvement of the reinforcement device for building construction cracks of the present invention is that the seepage prevention structure includes a slot and a block respectively disposed on one side of two templates that are in contact with each other. The slot and the block are disposed along the height direction of the templates. The block is used to be embedded in the slot when the two templates are in contact with each other to seal the contact point of the two templates.
[0010] A further improvement of the reinforcement device for building construction cracks of the present invention is that the two templates can be slidably connected to the corresponding frame in opposite directions or in opposite directions, and the reinforcement device further includes a fixing component for locking the relative sliding between the two templates.
[0011] A further improvement of the reinforcement device for building construction cracks of the present invention is that the reinforcement device further includes a reinforcement component for fixing two templates together.
[0012] A reinforcement method, implemented using the reinforcement device for building construction cracks as described above, includes the following steps: S1. Fix the two frames to the walls on both sides of the crack respectively; S2. Cross-wrap the tightening rope around multiple fixed shafts in the two fixed shaft groups and tighten it; S3. Pour repair material into the crack, allowing it to harden and form an adhesive bond that anchors to the walls on both sides.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention applies opposing pre-tightening forces to the walls on both sides of the crack by fixing two frames to the walls on both sides of the crack, and then tightening the tightening ropes by crisscrossing and wrapping them around multiple fixed shafts in the two fixed shaft groups. Finally, the crack is repaired by pouring repair material into it, which greatly improves the stability of the repair and results in a good repair effect. Attached Figure Description

[0021] To address the problem of poor repair effects of traditional crack reinforcement methods, this invention provides a reinforcement device and method for cracks in building construction. The following detailed description, in conjunction with the accompanying drawings, further illustrates this reinforcement device and method for cracks in building construction.
[0022] See Figures 1-6 As shown, a reinforcement device for cracks in building construction includes: Two frames 1 are used to fix them to the walls on both sides of the crack, respectively; Two fixed shaft groups 2 are fixed on two frames 1 respectively. Each fixed shaft group 2 includes multiple fixed shafts 2, and the multiple fixed shafts 2 are arranged at intervals along the height direction of the corresponding frame 1. The tightening rope 3 is crisscrossed and wound around multiple fixed shafts 2 in the two fixed shaft groups 2, used to continuously apply opposing preload to the two frames 1; and The adhesive is formed by pouring repair material into the crack and allowing it to cure, and the resulting adhesive is anchored to the walls on both sides.
[0023] Specifically, in this embodiment, refer to Figure 2 and 4As shown, frame 1 includes two vertical plates 101, three horizontal plates 102, two stiffening rods 103, two sets of screw holes 105, and two sets of bolts 104. The two vertical plates 101 are vertically arranged and opposite to each other. The three horizontal plates 102 are all fixedly connected between the two vertical plates 101, and the three horizontal plates 102 are spaced apart along the length of the area between the two vertical plates 101, forming as shown in the attached figure. Figure 2 The two openings shown are provided. The two stiffening rods 103 are X-shaped and fixed in the two openings respectively. The two sets of screw holes 105 are respectively set on the two vertical plates 101. Each set of screw holes 105 includes multiple screw holes 105, and the multiple screw holes 105 are spaced apart along the height direction of the corresponding vertical plate 101. The two sets of bolts 104 are respectively set corresponding to the two sets of screw holes 105, and each set of bolts 104 includes multiple bolts 104. The multiple bolts 104 pass through the corresponding multiple screw holes 105 and are fixed to the wall, so that the frame 1 can be firmly fixed to the wall. Furthermore, each fixed shaft group has five fixed shafts 2, and the five fixed shafts 2 are respectively fixedly connected to three horizontal plates 102 and two stiffening rods 103; By fixing two frames 1 to the walls on both sides of the crack, and then using tightening ropes 3 to cross-wrap around multiple fixed shafts 2 in the two fixed shaft groups and tighten them, opposing pre-tightening forces can be applied to the walls on both sides of the crack. Then, by pouring repair material into the crack for repair, the stability of the repair can be greatly improved and the repair effect is good.
[0024] The two frames 1 are arranged opposite each other, and a pouring cavity for pouring repair material into the crack is formed between the two frames 1.
[0025] See Figure 2 and 3 As shown, the reinforcement device also includes two templates 4, which are respectively connected to the opposite side of the two frames 1, and each of the two templates 4 has a notch 8 at the end away from the corresponding frame 1. When the two frames 1 are fixed to the walls on both sides of the crack, the two templates 4 are attached to each other so that the two gaps 8 are combined to form a pouring cavity that communicates with the crack and covers the crack in the wall, and a pouring port is formed at the upper end of the pouring cavity.
[0026] The cracks on the wall surface are covered by the casting cavity formed by the template 4. Then, the repair material (which can be concrete) is poured into the casting cavity through the upper casting port, so that the repair material flows into the crack for repair, which facilitates the casting and repair construction and avoids material waste.
[0027] The reinforcement device also includes a reinforcement body, which is formed by pouring repair material into the casting cavity and then curing it. The reinforcement body, the adhesive body, the walls on both sides of the crack, and the two templates 4 are anchored into a whole.
[0028] By adopting the above design, when the repair material is poured into the pouring cavity, the repair material in the pouring cavity will flow into the crack, and the remaining repair material in the pouring cavity will seal the crack, which can avoid the phenomenon of uncured repair material flowing back into the crack, thereby ensuring a good repair effect. Moreover, after the repair material in the pouring cavity is cured, the solidified body and adhesive body formed, the walls on both sides of the crack, and the two templates 4 are anchored into a whole, which can greatly improve the reinforcement effect of the wall.
[0029] Among them, see Figure 2 and 3 As shown, the reinforcement device also includes a seepage-proof structure installed on the two templates 4 to prevent leakage from the pouring cavity at the point where the two templates 4 are in contact.
[0030] The seepage prevention structure includes a slot 7 and a block respectively set on one side of the two templates 4 that are attached. The slot 7 and the block are set along the height direction of the template 4. The block is used to be embedded in the slot 7 when the two templates 4 are attached to seal the attachment point of the two templates 4.
[0031] By adopting the above design, the joint between the slot 7 and the block can be sealed at the connection between the two templates 4, thus preventing leakage when pouring repair material into the pouring cavity.
[0032] The two templates 4 can be slidably connected to the corresponding frame 1 in opposite directions or in opposite directions. The reinforcement device also includes a fixing component for locking the relative sliding between the two templates 4.
[0033] For details, please refer to Figure 3 , 4 As shown in Figure 6, in this embodiment, there is a gap between the three horizontal plates 102 on the frame 1 and the wall. The vertical plate 101 of the frame 1 near the crack has three openings 402 that communicate with the gap. The template 4 is fixedly connected to three connecting plates 401 that are slidably connected in the three openings 402 on the side away from the notch 8. The fixing component includes six concrete blocks 6, which are divided into groups of three and formed in the three gaps on the two frames 1 respectively. They can block the connecting plates 401, so that the two templates 4 are tightly attached together to achieve fixing. Further, see Figure 6 As shown, when the screw hole 105 on the frame 1 is connected to the through opening 402, the movable opening 403 can be passed through the connecting plate 401, so that the bolt 104 can pass through the screw hole 105 and the movable opening 403 and be fixed to the wall without affecting the normal sliding adjustment of the connecting plate 401. By adopting the above design, the ease of use and robustness of template 4 in this application are greatly improved.
[0034] The reinforcement device also includes a reinforcement component 5 for fixing the two templates 4 together.
[0035] Further, see Figure 1 and 5 As shown, the reinforcement component 5 includes two fixing plates 501, multiple screws 502, multiple pairs of nuts 503, and multiple pairs of through holes. The two fixing plates 501 are arranged opposite each other and are fixed to the side of the template 4 away from the wall. The longitudinal direction of the two fixing plates 501 is consistent with the longitudinal direction of the template 4. Each pair of through holes is opened on the two fixing plates 501. Multiple pairs of through holes are arranged at intervals along the longitudinal direction of the fixing plates 501. Multiple screws 502 are inserted into multiple pairs of through holes. Multiple pairs of nuts 503 are screwed to the two ends of multiple screws 502. By tightening the nuts 503 on both sides to press against the fixing plate 501, the two templates 4 can be firmly fixed together.
[0036] A reinforcement method, implemented using a reinforcement device for building construction cracks as described above, includes the following steps: S1. Fix the two frames 1 to the walls on both sides of the crack respectively; S2. Cross-wrap the tightening rope 3 around multiple fixed shafts 2 in the two fixed shaft groups 2 and tighten it; S3. Pour repair material into the crack, allowing it to harden and form an adhesive bond that anchors to the walls on both sides.
