Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to an expansion reinforcement strip structure for concrete crack construction. Background Technology

[0002] With the rapid development of the national economy, the demand for the construction of a large number of extra-long concrete buildings and structures is constantly increasing. In recent years, extensive engineering practice has proven that using expansion reinforcement strips in extra-long concrete structures allows for continuous construction without joints or cracks, reducing the hassle of joint treatment, significantly shortening the construction period, and achieving remarkable economic benefits. Expansion reinforcement strips are an engineering technique that involves pouring a higher grade of shrinkage-compensating concrete at the pre-designed post-cast strip location, reducing or eliminating post-cast strips and expansion joints, and extending the continuous casting length of the component. Existing expansion reinforcement strip structures use dense wire mesh to separate the inner and outer sides of the reinforcement strip. However, the wire mesh area is relatively large, making it prone to deformation under the impact of concrete, and severe damage can occur. Furthermore, the maintenance and replacement of the wire mesh is quite troublesome.

[0003] For example, patent document CN220848091U discloses an expansion reinforcement strip structure for concrete crack construction, including top reinforcement bars, bottom reinforcement bars, and a fixing frame. Two top reinforcement bars, two bottom reinforcement bars, and two fixing frames are provided, with the two top reinforcement bars located above the two bottom reinforcement bars. An adjustment mechanism is provided between the fixing frame and the top and bottom reinforcement bars. The fixing frame has a through hole inside and an insertion hole at its top. Multiple mounting brackets are slidably connected inside the insertion hole. A wire mesh is provided inside each mounting bracket. A positioning block is fixedly connected to the bottom of each mounting bracket. A positioning hole is provided at the bottom of the through hole, and the mounting bracket is engaged with the fixing frame through the positioning block and the positioning hole.

[0004] Although the aforementioned expansion reinforcement strip structure divides a large area of ​​wire mesh into smaller pieces, avoiding the problem of deformation and damage to a large area of ​​wire mesh under pressure, the above expansion reinforcement strip structure still has the following problems during use:

[0005] (1) During the use of the above-mentioned expansion reinforcement strip structure, the transverse reinforcing bars (top and bottom bars of the slab) cannot be adjusted in height, resulting in a dimensional deviation between them and the placement area. When the size of the transverse reinforcing bars is larger than the size of the placement area, the transverse reinforcing bars cannot be used.

[0006] (2) When the wire mesh is divided into small pieces, it is used in conjunction with a fixed frame and multiple fixed frames are spliced ​​together. However, no reinforcement structure is set for the use of multiple fixed frames, which makes it easy to disperse under the impact of concrete when pouring concrete, which is not conducive to use.

[0007] Therefore, there is an urgent need to design an expansion reinforcement strip structure for concrete crack construction to solve the above problems. Summary of the Invention

[0008] To address the problems of existing expansion reinforcement strip structures, such as the inability to adjust the transverse reinforcing bars during use, leading to dimensional deviations between the existing structure and the placement area, rendering the transverse reinforcing bars unusable, and the lack of a reinforcing structure causing the fixed frames to easily disperse under the impact of concrete, this utility model provides an expansion reinforcement strip structure for concrete crack construction, including an upper support frame and a lower support frame, with an adjustment mechanism, a reinforcing mechanism, and several wire frames provided between the upper and lower support frames. The adjustment mechanism is used to adjust the relative distance between the upper and lower support frames, and the reinforcing mechanism is used to reinforce the several wire frames inserted in the upper and lower support frames.

[0009] By using the above-mentioned multiple structures in combination, the relative distance between the two horizontal support plates and the two vertical support plates can be easily and synchronously adjusted to adapt to different sizes of the placement area and avoid unusable situations. At the same time, the reinforcing mechanism strengthens multiple wire frames to prevent them from dispersing under the large impact of concrete.

[0010] The core technical concept of this utility model is as follows: on the basis of achieving convenient and efficient adjustment, the reinforcing belt structure is set up as an upper and lower support structure composed of two upper and lower support frames. Then, the steel wire frame, the adjustment mechanism and the reinforcing mechanism are set together between the upper and lower support frames to adjust the distance between the upper and lower support frames to adapt to different placement areas, and to reinforce the steel wire frame to prevent multiple steel wire frames from being unable to withstand the impact force and thus becoming scattered.

[0047] Example:

[0048] See attached document Figure 1-6 The expansion reinforcement strip structure for concrete crack construction shown includes an upper support frame 1, a lower support frame 2, several wire frames 3, an adjustment mechanism 4, and a reinforcement mechanism 5. The lower support frame 2 is arranged parallel to the upper support frame 1 and is not on the same horizontal plane. It is used to place the expansion reinforcement strip in the placement area. Several wire frames 3 are movably inserted on both sides of the upper support frame 1 and the lower support frame 2 to splice them into an integral mesh wall, which facilitates the pouring of concrete and expansion concrete. The adjustment mechanism 4 is symmetrically arranged on the other two sides of the upper support frame 1 and the lower support frame 2. For example, there are two adjustment mechanisms 4, which are used to adjust the relative distance between the support frame 1 and the lower support frame 2 so that they can adapt to different depths of the placement area. The reinforcement mechanism 5 is arranged on both sides of the upper support frame 1 and the lower support frame 2 and is adapted to the wire frames 3 to further reinforce them and prevent damage and deformation.

[0049] For details, please refer to the attached document. Figure 2 As shown, the upper support frame 1 and the lower support frame 2 have the same structure, both being rectangular structures, including an upper support rod 101 and a support rod 2 102 that are connected to each other. For example, the adjustment mechanism 4 is provided on the support rod 2 102, and the reinforcing mechanism 5 is provided on the support rod 101.

[0050] For details, please refer to the attached document. Figure 3As shown, the adjustment mechanism 4 includes two sliders 401, two slide rods 402, and a drive assembly 403. The two sliders 401 are slidably locked in the transverse support top plate 1, that is, on the support rod 102 in the support top plate 1. The two slide rods 402 are respectively hinged to the sliders 401 and the movable sleeve 403 through hinge seats. The drive assembly 403 is set in the lower support frame 2 and is hinged to the slide rods 402.

[0051] The specific structure of the two sliders 401 set on the support rod 102 in the support top plate 1 is as follows: the support rod 102 has a slot 102-1. For example, the slot 102-1 can be set as a T-shaped slot. The slider 401 is locked in the slot 102-1 and can slide freely back and forth. For example, the slider 401 can be set as a T-shaped structure to cooperate with the T-shaped slot.

[0052] Furthermore, the drive assembly 403 includes a drive screw 403-1 and two movable sleeves 403-2.

[0053] The drive screw 403-1 is movably inserted into the support rod 102 in the lower support frame 2 and is rotatably connected to it; the two movable sleeves 403-2 are movably sleeved on the drive screw 403-1 and are hinged to the slide rod 402 through the hinge seat.

[0054] Specifically, a rotating groove is provided in the support rod 102 in the lower support frame 2. The drive screw 403-1 is movably inserted into the rotating groove from one side of the support rod 102 and is rotatably connected to the bottom of the rotating groove. A knob is provided at the free end of the drive screw 403-1. By rotating the knob, the drive screw 403-1 can be driven to rotate in the rotating groove. The drive screw 403-1 has two sets of external threads symmetrically provided, and the thread directions of the two sets of external threads are opposite. The movable sleeve 403-2 is used in conjunction with the two opposite external threads. When the drive screw 403-1 rotates, the movable sleeve 403-2 will move towards the opposite direction under the action of the opposite external threads.

[0055] For details, please refer to the attached document. Figure 4-5 As shown, the reinforcing mechanism 5 includes two sliders 501, a reinforcing rod 502, and a T-shaped positioning member 503. The two sliders 501 are slidably locked on the lower side of the support rod 101 of the upper support frame 1. The connection method between the sliders 501 and the support rod 101 is the same as the specific structure of the support rod 102 in the support top plate 1, which will not be described in detail here. The reinforcing rod 502 is hinged to the sliders 501 and the T-shaped positioning member 503 through hinge seats respectively. The T-shaped positioning member 503 is connected to the support rod 101 of the lower support frame 2.

[0056] Furthermore, the T-shaped positioning component 503 is provided with several threaded holes 503-1, and bolts are fitted into the threaded holes 503-1. The bolts are fitted into several threaded holes 202 on the support rod 101 of the lower support frame 2. In use, the bolts can be fixed to the support rod 101 of the support frame 2 by cooperating with the threaded holes 503-1 and the threaded holes 202, which is used to strengthen the fixing effect of the wire frame 3. There are multiple threaded holes 202, and the fixing position of the T-shaped positioning component 503 can be adjusted according to the number of wire frames 3, so as to better support the wire frame 3.

[0057] For details, please refer to the attached document. Figure 6 As shown, a limiting block 301 is provided at the bottom of the wire frame 3. The limiting block 301 is adapted to the limiting groove 201 opened on the lower support frame 2. The wire frame 3 moves through the through groove 103 opened on the upper support frame 1. In use, the wire frame 3 is inserted through the through groove 103 on the support frame 1, so that it moves down and the limiting block 301 enters the limiting groove 201, thereby completing the installation of a wire frame 3.

[0058] The usage process of the expansion reinforcement strip structure for concrete crack construction in this embodiment is as follows: First, adjust the relative distance between the upper support frame 1 and the lower support frame 2 according to the depth of the placement area. Specifically, turn the knob, which drives the drive screw 403-1 to rotate. The rotation of the drive screw 403-1 causes the moving sleeve 403-2 to move towards each other, thereby driving the slide rod 402 to move. At the same time, the included angle between it and the lower support frame 2 also changes.

[0059] Subsequently, the wire frames 3 are inserted sequentially through the through slots 103 on the support frame 1, causing them to move downwards and the limiting block 301 to enter the limiting slot 201, thereby completing the installation of one or more wire frames 3. Based on the installed wire frames 3, the position of the T-shaped positioning piece 503 on the support rod 101 of the support frame 2 is adjusted, thereby adjusting the support position of the reinforcing rod 502 on the wire frames 3 to maximize its support effect.

[0060] Finally, the adjusted upper support frame 1 and lower support frame 2 are placed in the placement area, concrete is poured on the outside of the wire frame 3, and expansive concrete is poured on the inside of the wire frame 3, thus completing the construction.
