Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air wall crack reinforcement, in particular to a building construction crack reinforcement device. Background Art
[0002] After long-term use, the bearing capacity of buildings will decrease due to various reasons. This is mainly manifested in cracks in the walls of old buildings due to settlement and other reasons. In order to prevent the cracks from continuing to deteriorate or increase, it is necessary to reinforce the walls of the buildings with cracks in time. Generally, the width of the cracks will be fixed through crack reinforcement devices to reinforce the walls.
[0003] The existing crack reinforcement device relies on two pull ropes to tighten two reinforcement splints to limit the cracks. The pull ropes are prone to breakage when subjected to the tension of the two walls. A further improved design uses screws to fix the two reinforcement splints to reinforce the cracks, but the degree of adjustability is low.
[0004] The Chinese patent with the authorization announcement number CN219732865U discloses a construction crack reinforcement device, including a horizontal plate, guide columns are symmetrically embedded in the horizontal plate at both ends, the guide columns are slidably sleeved with a slide seat, the bottom of the slide seat is detachably connected to a reinforcement splint, the top of the horizontal plate is symmetrically rotatably connected to a plurality of screw rods, the slide seat is threadedly sleeved on the screw rods, both sides of the horizontal plate are detachably connected to positioning studs, both sides of the top of the reinforcement splint are connected to connecting seats, and the connecting seats are slidably sleeved on the positioning studs. The distance between the two reinforcement splints is changed by sliding the slide seat horizontally along the guide column, thereby adapting to cracks of different widths. The rotation of the screw rod can drive the slide seat to slide horizontally along the guide column to change the position of the reinforcement splint, and can also fix the position of the reinforcement splint, or can fix the connecting seat at any position on the positioning stud. When reinforcing cracks at a specified position, the position of the reinforcement splint can be locked together by fixing the position of the slide seat and the position of the connecting seat.
[0005] However, some buildings have curved walls. When cracks appear on the curved walls, the above-mentioned patent is difficult to be stably and firmly installed on the walls, and the curved walls cannot be tightened and reinforced. Utility Model Content
[0006] In order to overcome the deficiencies of the prior art, the utility model solves the technical problem of providing a rotatable rotating plate, and changing the inclination angle of the two rotating plates by rotating the screw, so that the two reinforcing bolts can be fixed perpendicular to the curved wall, thereby improving the fixing stability when pulling and reinforcing the gap, and improving the reinforcement effect, by rotating the two bidirectional lead screws, so that the two sliders carry the two reinforcing bolts to tighten the two sides of the wall crack, thereby reinforcing the wall crack, and by providing a support block, it rests on the curved wall during the tightening process, providing a better reinforcement effect, and by providing a first gear and a second gear meshing transmission, and since the diameter of the first gear is smaller than that of the second gear, it has a labor-saving effect, thereby facilitating the workers to carry out the crack reinforcement work conveniently and labor-savingly, thereby improving work efficiency.
[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction crack reinforcement device, comprising a slide rail, two sliders symmetrically distributed and slidably connected between two of the slide rails, two mutually symmetrical first axle seats fixedly connected on one side of the two sliders, two mutually symmetrical rotating plates rotatably connected to the two first axle seats respectively, and a reinforcement bolt connected to the end of each rotating plate.

[0009] Two end covers are fixedly connected to the two ends of the two slide rails, two bidirectional lead screws are rotatably connected between the two end covers, and both ends of each bidirectional lead screw are threadedly connected to the slider.
[0010] A support block is fixedly connected in the middle of the two slide rails, and the support block is rotatably connected to the two bidirectional lead screws.
[0011] The ends of the two bidirectional lead screws extending out of the end covers are respectively fixedly connected to the first gears, and a pressure plate is fixedly connected to the end covers at the corresponding positions of the first gears. A rotating shaft is rotatably connected at the center of the pressure plate, and a second gear with a smaller diameter than the first gear is fixedly connected to the end of the rotating shaft passing through the pressure plate, and the second gear is meshed and transmission-connected with the two first gears.
[0012] In summary, compared with the prior art, the beneficial effects of the present invention are:
[0013] By providing a rotatable rotating plate and changing the inclination angle of the two rotating plates by rotating the screw rod, the two reinforcing bolts can be fixed perpendicularly to the curved wall, thereby improving the fixing stability when pulling the reinforced gap and improving the reinforcement effect.
[0014] By setting support blocks, they rest against the curved wall during the tensioning process, providing better reinforcement effect.
[0015] By setting the first gear and the second gear to mesh and transmit, and because the diameter of the first gear is smaller than that of the second gear, it saves effort, making it convenient for workers to carry out crack reinforcement work with less effort, thereby improving work efficiency.

[0020] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.
[0021] refer to Figure 1-4 A construction crack reinforcement device comprises a slide rail 10, two slide rails 10 are symmetrically distributed and slidably connected with two sliders 11, one side of the two sliders 11 is fixedly connected with two mutually symmetrical first shaft seats 12, the two first shaft seats 12 are respectively rotatably connected with two mutually symmetrical rotating plates 13, the end of each rotating plate 13 is connected with a reinforcement bolt 14, a group of second shaft seats 15 are fixedly connected to each rotating plate 13, a rotating head 16 is rotatably connected in each group of second shaft seats 15, a rotating seat 17 is rotatably connected at the end of each slide rail 11, a screw 18 is internally threadedly connected to each rotating seat 17, an end of each screw 18 is rotatably connected to the corresponding rotating head 16, and a hand wheel 19 is fixedly connected to the end of each rotating seat 17 away from the rotating head 16.
[0022] By providing a rotatable rotating plate 13 and changing the inclination angle of the two rotating plates 13 by rotating the screw rod 18, the two reinforcing bolts 14 can be fixed perpendicularly to the curved wall, thereby improving the fixing stability when pulling the reinforcing gap and improving the reinforcement effect.
[0023] refer to Figure 2 Two end covers 26 are fixedly connected at both ends of the two slide rails 10, and two bidirectional lead screws 20 are rotatably connected between the two end covers 26. Both ends of each bidirectional lead screw 20 are threadedly connected to the slider 11. A support block 21 is fixedly connected in the middle of the two slide rails 10, and the support block 21 is rotatably connected to the two bidirectional lead screws 20.
[0024] By rotating the two bidirectional lead screws 20, the two sliders 11 carry the two reinforcement bolts 14 to tighten the two sides of the wall crack, thereby reinforcing the wall crack. By setting the support block 21, it rests on the curved wall during the tightening process, providing a better reinforcement effect.
[0025] refer to Figure 2-3 The ends of the two bidirectional lead screws 20 extending out of the end covers 26 are respectively fixedly connected to the first gears 24, and a pressure plate 22 is fixedly connected to the end covers 26 at the corresponding positions of the first gears 24. A rotating shaft 23 is rotatably connected to the center of the pressure plate 22. The rotating shaft 23 passes through the end of the pressure plate 22 and is fixedly connected to a second gear 25 with a diameter smaller than the first gear 24. The second gear 25 is meshed and transmission-connected with the two first gears 24.
[0026] By setting the first gear 24 and the second gear 25 to mesh and transmit, and because the diameter of the first gear 24 is smaller than that of the second gear 25, it saves effort, thereby making it convenient for workers to carry out crack reinforcement work with less effort, thereby improving work efficiency.
[0027] In this embodiment, initially, the rotating plates 13 on both sides are in a straight state, the reinforcing bolts 14 are not yet connected to the two rotating plates 13 , and the two first shaft seats 12 are respectively located at the two ends of the slide rail 28 .
[0028] When the cracks in the wall need to be reinforced, the workers first use tools such as drill bits to drill holes on both sides of the cracks in the curved wall, and then the workers put the device at the drilling position, and then respectively turn the hand wheel 19 to rotate the screw 18, and the screw 18 is threadedly connected to the rotating seat 17. During the rotation of the screw 18, the rotating plate 13 is continuously pushed to make the rotating plate 13 gradually tilted until the end of the rotating plate 13 corresponds to the drilling position of the curved wall.
[0029] Subsequently, the worker installs the reinforcing bolts 14 on the two rotating plates 13 and inserts them into the drilled holes on the wall, and uses tools such as pneumatic wrenches to firmly screw the reinforcing bolts 14 into the curved wall, so that the device can be firmly installed on the wall in accordance with the curvature of the curved wall.
[0030] Afterwards, the worker uses the pneumatic wrench to rotate the rotating shaft 23 again, and drives the two bidirectional screws 20 to rotate through the meshing transmission of the second gear 25 and the first gear 24, so that the two sliders 11 drive the two reinforcing bolts 14 to approach each other, pulling the walls on both sides of the crack, thereby reinforcing the crack and preventing the wall from further cracking.
[0031] At this time, the support block 21 is firmly against the curved wall, and cooperates with the tightening of the two reinforcement bolts 14 to provide a more stable and firm support for the curved wall, thereby improving the reinforcement effect.
[0032] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
[0033] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system.
