Description

Technical Field

[0001] The utility model relates to the technical field of shear walls, in particular to a reinforced concrete shear wall replacement reinforcement device. Background Art

[0002] Shear walls can be divided into reinforced concrete shear walls, steel plate shear walls, steel concrete shear walls and reinforced block shear walls according to their structural materials. Among them, reinforced concrete shear walls are the most commonly used. Reinforced concrete shear walls refer to a series of reinforced concrete walls set in the building structure with the main purpose of bearing horizontal loads (and also bearing vertical loads within the corresponding range).

[0003] Publication number "CN219365526U" provides a reinforced concrete shear wall replacement reinforcement device, including templates arranged on both sides of the replacement area of ​​the shear wall to be reinforced and a permanent support system supported between the top and bottom of the replacement area of ​​the shear wall to be reinforced. In the replacement area of ​​the shear wall to be reinforced, newly added horizontal distribution bars are arranged at the original horizontal distribution bar positions, and newly added vertical distribution bars are arranged at the original vertical distribution bar positions. The newly added horizontal distribution bars are welded to the original horizontal distribution bars reserved in the replacement area of ​​the shear wall to be reinforced, and the newly added vertical distribution bars are welded to the original vertical distribution bars reserved in the replacement area of ​​the shear wall to be reinforced. The utility model can improve the structural bearing capacity, and the cross-section of the shear wall after reinforcement is the same as the original design, and the use area is not lost in any way; the permanent support system has simple and clear force transmission, which can ensure construction safety, and does not need to set up a large number of scaffolding temporary support systems layer by layer; the self-compacting concrete has good fluidity, high strength, slight expansion, is conducive to vibration, and does not seep water.

[0004] However, the above device still has the following problems during implementation:

[0005] The strength of reinforced concrete shear walls may not meet the construction standards due to improper materials and construction. In this case, the replacement concrete reinforcement method is often used to replace the concrete in the shear wall. The shear wall is then restricted by formwork and reinforced by a keel frame. A large amount of temporary scaffolding support is then required. The process is very cumbersome and inconvenient for users. Utility Model Content

[0006] The utility model aims to provide a reinforced concrete shear wall replacement reinforcement device to solve the problems raised in the above-mentioned background technology.

[0009] The pinning mechanism is movably arranged on the longitudinal template, and can position the transverse keel and the longitudinal keel to improve the supporting effect.

[0010] Preferably, the pinning mechanism includes embedded grooves opened on both sides of the longitudinal keel for use with the transverse keel, two pulling rings are provided on the top of the longitudinal keel, and the bottom of the pulling ring is fixedly connected with a pin rod, and the top and bottom of the longitudinal keel are both provided with a first pin hole for use with the pin rod, and the top of the transverse keel is provided with a second pin hole for use with the pin rod.

[0012] The adjustment mechanism includes an adjustment frame fixedly connected to one side of the support frame, an adjustment disk is provided on one side of the adjustment frame, an adjustment rod is fixedly connected to one side of the adjustment disk, one end of the adjustment rod passes through one side of the adjustment frame and is fixedly connected to a first bevel gear, the top and bottom of the first bevel gear are meshed and connected to the second bevel gear, the side of the second bevel gear away from the first bevel gear is fixedly connected to a threaded rod, the surface of the threaded rod is transmission-connected to a connecting block, and one side of the connecting block is fixedly connected to one side of the transverse keel.

[0013] Preferably, one side of the connecting block is fixedly connected to a limiting block, and an inner wall of the adjusting frame is provided with a limiting groove used in conjunction with the limiting block.

[0014] Preferably, a first bearing seat is sleeved on the surface of the adjusting rod, the first bevel gear is rotatably connected to the inner wall of the adjusting frame through the first bearing seat, and a second bearing seat is provided at one end of the threaded rod, and is rotatably connected to the inner wall of the adjusting frame through the second bearing seat.

[0016] Preferably, the number of the first pin holes and the number of the second pin holes are both plural, the first pin holes are distributed longitudinally, and the second pin holes are distributed transversely.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model takes into account that after the concrete in the shear wall is replaced, the shear wall needs to be restricted by the template, and then reinforced by the keel frame. After that, a large number of temporary scaffolding supports need to be erected, and the process is very cumbersome and not conducive to the use of users. Therefore, by setting a support frame, a universal wheel and a pin tightening mechanism, after the concrete in the shear wall is replaced, the two longitudinal templates and the two transverse templates can be attached to the corresponding positions of the wall. Then, when the support frame is moved, the support frame, with the cooperation of the universal wheel, drives the transverse keel to be in close contact with the transverse template to achieve the role of transverse support. Then, the embedded groove on the longitudinal keel is aligned with the transverse keel, and the plugs are connected together, so that the longitudinal keel supports the longitudinal template.

[0019] 2. The utility model takes into account that the height of the wall is different, and the position of the optimal support point will also be different. If the support position cannot be adjusted, the support effect will also be affected. Therefore, by setting an adjustment mechanism, the adjustment plate can be turned, and the adjustment plate will drive the adjustment rod and the first bevel gear to rotate around the first bearing seat. Since the first bevel gear and the second bevel gear are meshed, the second bevel gear and the threaded rod will be driven to rotate around the second bearing seat. During the rotation of the threaded rod, the external thread on its surface will squeeze the internal thread in the threaded hole, thereby adjusting the height of the connecting block and the horizontal keel, so as to achieve the effect of adjusting the support position;

[0020] In the present invention, by setting a support frame, a universal wheel and a pin tightening mechanism, it is possible to facilitate the support and reinforcement of the wall. At the same time, considering that the wall height is different, the optimal support point position will also be different. If the support position cannot be adjusted, it will also affect the support effect. Therefore, by setting an adjustment mechanism, the support position can be adjusted, which solves the problem that after the concrete in the shear wall is replaced, the shear wall needs to be restricted by a template and then reinforced by a keel frame. After that, a large number of temporary scaffolding supports need to be erected, and the process is very cumbersome and not conducive to user use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0029] Embodiment 1:

[0030] A reinforced concrete shear wall replacement reinforcement device comprises a wall body 1, two longitudinal formworks 2 and two transverse formworks 3, the two longitudinal formworks 2 and the two transverse formworks 3 are respectively arranged around the wall body 1, a longitudinal keel 4 is arranged on the side of the longitudinal formwork 2 away from the wall body 1, a transverse keel 5 is arranged on the side of the transverse formwork 3 away from the wall body 1, a support frame 6 for support is arranged on one side of the transverse keel 5, and four universal wheels 7 are fixedly installed on the bottom of the support frame 6;

[0031] The pinning mechanism is movably arranged on the longitudinal template 2, and can position the transverse keel 5 and the longitudinal keel 4 to improve the supporting effect;

[0032] One implementation method of the first embodiment is: the pinning mechanism includes an embedding groove 8 provided on both sides of the longitudinal keel 4 and used in conjunction with the transverse keel 5, two pulling rings 9 are provided on the top of the longitudinal keel 4, and a pin rod 10 is fixedly connected to the bottom of the pulling ring 9, a first pin hole 11 used in conjunction with the pin rod 10 is provided on the top and bottom of the longitudinal keel 4, and a second pin hole 12 used in conjunction with the pin rod 10 is provided on the top of the transverse keel 5;

[0033] In this embodiment, it is considered that after the concrete in the shear wall is replaced, the shear wall needs to be restricted by the template, and then reinforced by the keel frame. After that, a large number of temporary scaffolding supports need to be erected, and the process is very cumbersome and inconvenient for users to use. Therefore, by setting the support frame 6, the universal wheel 7 and the pin tightening mechanism, after the concrete in the shear wall is replaced, the two longitudinal templates 2 and the two transverse templates 3 can be attached to the corresponding positions of the wall body 1. Then, when the support frame 6 is moved, the support frame 6, with the cooperation of the universal wheel 7, drives the transverse keel 5 to be in close contact with the transverse template 3 to achieve the role of transverse support. Then, the embedded groove 8 opened on the longitudinal keel 4 is aligned with the transverse keel 5, and the plugs are matched together, so that the longitudinal keel 4 supports the longitudinal template 2. Then, the pulling ring 9 and the pin rod 10 are picked up and passed through the corresponding first pin hole 11 and the second pin hole 12 to complete the positioning between the transverse keel 5 and the longitudinal keel 4.

[0034] It solves the problem that after the concrete in the shear wall is replaced, the shear wall needs to be restricted by the formwork, and then reinforced by the keel frame, and then a large number of temporary scaffolding supports need to be set up, which is a very cumbersome process and not conducive to user use;

[0035] It should be noted that the universal wheel 7 is a fixable caster, and this technical means is well known to those skilled in the art, so it will not be described in detail.

[0036] Preferably, the number of the first pin holes 11 and the number of the second pin holes 12 are both multiple, the first pin holes 11 are distributed longitudinally, and the second pin holes 12 are distributed transversely;

[0037] By setting the first pin hole 11 and the second pin hole 12, the present embodiment can improve the adaptability of the transverse keel 5 and the longitudinal keel 4 by setting a plurality of first pin holes 11 and second pin holes 12, which are respectively distributed longitudinally and transversely, and can make appropriate adjustments according to the wall 1 of different lengths and thicknesses.

[0038] Embodiment 2:

[0039] On the basis of the first embodiment, the support frame 6, the universal wheel 7 and the pin tightening mechanism in this embodiment can facilitate the support and reinforcement of the wall 1, but considering that the height of the wall 1 is different, the position of the optimal support point will also be different. If the support position cannot be adjusted, the support effect will also be affected. In this application, an adjustment mechanism is provided on one side of the support frame 6, which can adjust the support position and improve the support effect;

[0040] The adjustment mechanism includes an adjustment frame 13 fixedly connected to one side of the support frame 6, an adjustment disk 14 is provided on one side of the adjustment frame 13, an adjustment rod 15 is fixedly connected to one side of the adjustment disk 14, one end of the adjustment rod 15 passes through one side of the adjustment frame 13, and is fixedly connected to a first bevel gear 16, the top and bottom of the first bevel gear 16 are meshed and connected to a second bevel gear 17, a threaded rod 18 is fixedly connected to one side of the second bevel gear 17 away from the first bevel gear 16, a connection block 19 is transmission-connected to the surface of the threaded rod 18, and one side of the connection block 19 is fixedly connected to one side of the transverse keel 5;

[0041] This embodiment takes into account that the height of the wall 1 is different, and the position of the optimal support point will also be different. If the support position cannot be adjusted, the support effect will also be affected. Therefore, by setting an adjustment mechanism, the adjustment plate 14 can be turned, and the adjustment plate 14 will drive the adjustment rod 15 and the first bevel gear 16 to rotate around the first bearing seat 22. Since the first bevel gear 16 and the second bevel gear 17 are meshed, the second bevel gear 17 and the threaded rod 18 will be driven to rotate around the second bearing seat 23. During the rotation of the threaded rod 18, the external thread on its surface will squeeze the internal thread in the threaded hole 24, thereby adjusting the height of the connecting block 19 and the horizontal keel 5, so as to achieve the effect of adjusting the support position;

[0042] Solved the problem that the optimal support point position will be different if the height of wall 1 is different, and if the support position cannot be adjusted, it will also affect the support effect;

[0043] It should be noted that the adjustment mechanism for adjusting the support position needs to be operated before the pinning mechanism positions the transverse keel 5 and the longitudinal keel 4 .

[0044] Preferably, one side of the connecting block 19 is fixedly connected to a limiting block 20, and the inner wall of the adjusting frame 13 is provided with a limiting groove 21 used in conjunction with the limiting block 20;

[0045] In this embodiment, by setting the limit block 20 and the limit groove 21, when the threaded rod 18 rotates, the external thread squeezes the internal thread to transmit the connecting block 19, thereby limiting the connecting block 19 and other structures to slide only along the trajectory of the limit block 20 and the limit groove 21.

[0046] Preferably, a first bearing seat 22 is sleeved on the surface of the adjusting rod 15, and the first bevel gear 16 is rotatably connected to the inner wall of the adjusting frame 13 through the first bearing seat 22. A second bearing seat 23 is provided at one end of the threaded rod 18, and is rotatably connected to the inner wall of the adjusting frame 13 through the second bearing seat 23.

[0047] This embodiment provides the first bearing seat 22 and the second bearing seat 23 to support the first bevel gear 16 and the second bevel gear 17, thereby ensuring that the first bevel gear 16 and the second bevel gear 17 are always in meshing state and making the rotation process smoother.

[0048] Preferably, a threaded hole 24 for use with the threaded rod 18 is provided at the top of the connecting block 19, and the threads inside the two threaded holes 24 are opposite threads to each other;

[0049] In this embodiment, by setting the threaded holes 24, the internal threads of the two threaded holes 24 can be set as reverse threads. At this time, the two connecting blocks 19 drive the lateral keels 5 to move in opposite or relative trajectories, which can increase the adjustment rate.

[0050] Working principle: By twisting the adjustment disk 14, the adjustment disk 14 will drive the adjustment rod 15 and the first bevel gear 16 to rotate around the first bearing seat 22. Since the first bevel gear 16 and the second bevel gear 17 are meshed, the second bevel gear 17 and the threaded rod 18 will be driven to rotate around the second bearing seat 23. During the rotation of the threaded rod 18, the external thread on its surface will squeeze the internal thread in the threaded hole 24, thereby adjusting the height of the connecting block 19 and the transverse keel 5, so as to adjust the support position;

[0051] After the concrete in the shear wall is replaced, the two longitudinal formworks 2 and the two transverse formworks 3 are attached to the corresponding positions of the wall 1. When the support frame 6 is moved, the support frame 6, with the cooperation of the universal wheel 7, drives the transverse keel 5 to be in close contact with the transverse formwork 3 to achieve the role of transverse support. Then, the embedded groove 8 on the longitudinal keel 4 is aligned with the transverse keel 5, and they are plugged together so that the longitudinal keel 4 supports the longitudinal formwork 2. Then, the pulling ring 9 and the pin rod 10 are picked up and passed through the corresponding first pin hole 11 and the second pin hole 12 to complete the positioning between the transverse keel 5 and the longitudinal keel 4.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
