Description

Technical Field

[0001] This utility model relates to the technical field of construction equipment, specifically a concrete pouring formwork reinforcement device. Background Technology

[0002] Construction formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components in the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the formwork and the external loads acting on it, thus achieving the purpose of formwork engineering.

[0003] To prevent formwork deformation during concrete pouring, it is necessary to reinforce it. For example, a formwork fixing device for building engineering disclosed in Chinese Patent Publication No. CN217581240U uses two fixing plates to clamp the pouring formwork on opposite sides of the concrete structure to reinforce the formwork.

[0004] However, this technical solution cannot detect whether the concrete structure has completely cured after pouring. Detecting the curing of concrete structures usually requires workers to make a visual judgment, which will produce a certain degree of error. Therefore, it is impossible to determine whether the pouring formwork can be removed from the concrete structure.

[0005] Therefore, this application proposes a concrete pouring formwork reinforcement device. Utility Model Content

[0006] The purpose of this utility model is to provide a concrete pouring formwork reinforcement device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A concrete pouring formwork reinforcement device includes:

[0009] A connecting seat, wherein the connecting seat has a slot that penetrates the outer walls of its opposite sides;

[0010] The sliding block is provided in two parts and is respectively engaged with both sides of the slot, and the sliding block slides freely within the slot;

[0011] A clamping arm is fixed to the bottom of the sliding block, and the connecting seat has a clearance groove for the clamping arm to pass freely.

[0012] A driving component is disposed on the connecting base and is used to drive the two sliding blocks to move relative to each other;

[0013] A detection slider is engaged in the mounting hole of the clamping arm. The clamping arm is provided with a detection component, which is used to detect the movement of the detection slider relative to the clamping arm.

[0014] Furthermore, the driving component includes:

[0015] A rotating rod is mounted on the connecting seat and can rotate freely. The two ends of the rotating rod along its length are respectively provided with a first lead screw section and a second lead screw section, and the threads of the first lead screw section and the second lead screw section have opposite directions.

[0016] A threaded nut sleeve is inserted onto the sliding block, and two threaded nut sleeves are respectively threaded onto the first lead screw section and the second lead screw section.

[0017] Furthermore, a rotating handle is fixedly connected to one end of the rotating rod.

[0018] Furthermore, the detection component includes:

[0019] A fixed base is fixedly connected to the outer wall of the clamping arm. The fixed base has a sliding cavity for engaging the detection slider, and the detection slider slides freely horizontally within the sliding cavity.

[0020] A sliding rod is horizontally fixed to the detection slider, and the sliding rod extends out of the fixed base and slides freely;

[0021] An elastic element is disposed within the sliding cavity and elastically abuts against the detection slider in the direction of the outer side of the clamping arm;

[0022] A swing indicator is provided on the fixed base and is used to detect the horizontal movement of the sliding rod.

[0023] Furthermore, the elastic element is a spring wrapped around the sliding rod, with both ends of the spring elastically abutting against the detection slider and the inner wall of the sliding cavity, respectively.

[0024] Furthermore, the longitudinal section of the sliding rod is rectangular.

[0025] Furthermore, a guide sleeve is fixedly connected to one end of the fixed base away from the clamping arm. The guide sleeve has a through hole for the sliding rod to pass freely. A limiting pin is vertically inserted through the guide sleeve. The sliding rod has an oblong hole for the limiting pin to be inserted into the through hole.

[0026] Furthermore, the swing indicator includes:

[0027] A swinging part is rotatably connected to the fixed base, and the fixed base has a mounting cavity for mounting the swinging part;

[0028] A swaying piece, the swaying piece being fixed to the periphery of the swaying part;

[0029] A transmission unit is provided on the sliding rod and is used to drive the swing part to rotate when the sliding rod moves horizontally.

[0030] Furthermore, the transmission unit includes a rack portion disposed on the upper surface of the sliding rod, and the swing portion is provided with a gear portion that meshes with the rack portion.

[0031] Furthermore, the outer wall of the fixed base is provided with scale lines that cooperate with the swing plate.

[0032] Compared with the prior art, the beneficial effects of this utility model are:

[0033] This invention uses a drive assembly to drive two sliding blocks to move closer together, allowing two clamping arms to grip the external casting template, thus reinforcing the concrete structure and preventing edge collapse after pouring. Additionally, by incorporating a detection slider and detection assembly, after the concrete structure solidifies, internal air is expelled and the volume shrinks, creating a gap between the clamping arms and the template surface. The detection slider is then pushed towards this gap by the elastic resistance of the detection assembly. During this movement, the detection assembly detects the slider's motion, allowing workers to determine whether the concrete structure has solidified.

[0034] This utility model, by setting up a rack, a gear and a swinging part, allows the detection slider to move so that the rack and gear mesh and drive each other, which in turn drives the swinging part to rotate, causing the swinging part to drive the swinging plate to swing, thereby causing the swinging plate to swing with a large amplitude, which makes it easier for the staff to observe.

[0035] This invention uses scale lines to indicate the position of the oscillating plate after it swings, thus making it easier for workers to determine whether the concrete structure has cured. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please see Figures 1-5 This utility model provides a technical solution: a concrete pouring formwork reinforcement device, including a connecting seat 8 whose length is much larger than its width. The connecting seat 8 has slots 13 penetrating its opposite outer walls. Two sliding blocks 10, capable of horizontal free sliding, are engaged within the slots 13, located on opposite sides of the slots 13. A clamping arm 4 is welded to the bottom of each sliding block 10. The upper end of the clamping arm 4 is narrower than its lower end. The bottom of the connecting seat 8 has a section for the upper end of the clamping arm 4 to pass freely. The clearance groove 11 has two sliding blocks 10 each with a threaded nut 5. A rotating rod 7 is horizontally inserted on the connecting seat 8 and can rotate freely on the connecting seat 8. The two ends of the rotating rod 7 in the length direction are respectively provided with a first threaded rod section 6 and a second threaded rod section 9. The threads of the first threaded rod section 6 and the second threaded rod section 9 have opposite directions. The two threaded nut 5 are respectively threaded onto the first threaded rod section 6 and the second threaded rod section 9. In addition, a rotating handle is fixedly connected to one end of the rotating rod 7. The rotating rod 7 can be rotated by the operator manually rotating the handle.

[0044] Immediately after pouring, the concrete structure is relatively soft and prone to collapse at the edges. Workers place formwork at the edges of the concrete structure to limit edge collapse. After these standard procedures, the connecting seat 8 is placed across the top of the concrete structure, with its length aligned with the width. The two clamping arms 4 are positioned on either side of the concrete structure and are in contact with the formwork surface. The worker then manually rotates the handle, which in turn rotates the rotating rod 7. As the rod 7 rotates, it drives the first screw... The rod segment 6 and the second lead screw segment 9 rotate, and then engage with the two threaded sleeves 5. When the threads are engaged, the two sliding blocks 10 will move closer to each other, and the two clamping arms 4 will move towards each other, clamping the template and squeezing it, making the edge of the concrete structure less prone to collapse. When the edge of the concrete structure is reinforced, the concrete structure begins to solidify, and its volume changes from the original soft state to a shrinking state (with a small degree of shrinkage). Since the threaded connection has self-locking properties, the threaded sleeve 5 will be in a locked state after the threads of the first lead screw segment 6 and the second lead screw segment 9 are engaged.

[0045] A cylindrical fixing seat 2 is welded to the outer wall of the clamping arm 4 on the side facing away from the concrete structure. The axial direction of the fixing seat 2 is parallel to the thickness direction of the clamping arm 4. A sliding cavity 20 is formed inside the fixing seat 20, and a freely sliding detection slider 1 is engaged in the sliding cavity 20. An installation hole is formed on the outer wall of the clamping arm 4 to allow the detection slider 1 to pass freely. A sliding rod 22 is horizontally welded to the end face of the detection slider 1 away from the concrete structure. The longitudinal section of the sliding rod 22 is rectangular. The sliding rod 22 extends out of the fixing seat 2 and can slide freely on the fixing seat 2. A spring 21 is wound around the sliding rod 22. The spring 21 is located inside the sliding cavity 20, and the two ends of the spring 21 elastically abut against the detection slider 1 and the sliding cavity, respectively. The inner wall of the sliding rod 22 has a rack portion 19 on its upper surface. The fixed seat 2 has a mounting cavity 14 that communicates with the sliding cavity 20. The fixed seat 2 is rotatably connected to a swing portion 16 located in the mounting cavity 14. The swing portion 16 has a gear portion on its periphery, which meshes with the rack portion 19. In addition, a swing plate 15 is welded on the periphery of the swing portion 16. The upper end of the swing plate 15 extends out of the mounting cavity 14. In addition, the fixed seat 2 has multiple scale lines on its periphery. The scale lines are equally spaced along the axial direction of the fixed seat 2. The swing plate 15 works in conjunction with the scale lines. That is, if the scale lines corresponding to the positions where the swing plate 15 stops before and after swinging do not overlap, it can be determined that the swing plate 15 has swung.

[0046] When the concrete structure is cured, its volume will shrink to a certain extent, and the template will adhere to the surface of the concrete structure. Since the clamping arm 4 is in a fixed state, the distance between the clamping arm 4 and the template will change, resulting in a gap between the surface of the clamping arm 4 and the surface of the template. Under the elastic resistance of the spring 21, the detection slider 1 moves into the gap. When the detection slider 1 moves, the sliding rod 22 moves synchronously, so that the rack part 19 meshes with the gear part, thereby driving the swing part 16 to swing. In this way, the swing plate 15 swings synchronously, and the swing angle of the swing plate 15 is large, so that even when the movement stroke of the detection slider 1 is small, the swing plate 15 can also produce a certain degree of swing. The staff records the scale line corresponding to the stopping position of the swing plate 15 before and after reinforcement. When the span between the scale lines of the two states is large, it can be determined that the concrete has been cured in place.

[0047] In addition, a guide sleeve 3 is fixedly connected to the end of the fixed base 2 away from the clamping arm 4. The guide sleeve 3 has a through hole for the sliding rod 22 to pass through freely. A limiting pin 17 is vertically inserted through the guide sleeve 3. The sliding rod 22 has an oblong hole 18 for the end of the limiting pin 17 to be inserted into the through hole. By inserting the limiting pin 17 into the oblong hole 18, when the template is not reinforced, after the detection slider 1 moves into place, the swing plate 15 is exactly in the middle of multiple scale lines. This makes it convenient to observe the scale lines of the swing plate 15 before and after the concrete structure is cured.

[0048] The working principle of this utility model is as follows: The connecting seat 8 is placed horizontally above the concrete structure, with the length direction of the connecting seat 8 consistent with the width direction of the concrete structure. The two clamping arms 4 are located on both sides of the concrete structure, and the clamping arms 4 are in contact with the template surface on the concrete structure. Then, the worker manually rotates the handle, which drives the rotating rod 7 to rotate. When the rotating rod 7 rotates, it drives the first lead screw section 6 and the second lead screw section 9 to rotate, and then engages with the two threaded nuts 5. When the threads are engaged, the two sliding blocks 10 will move closer to each other, and the two clamping arms 4 will move towards each other, clamping the template and squeezing it. This makes the edge of the concrete structure less prone to collapse. When the edge of the concrete structure is reinforced, the concrete structure begins to solidify, and its volume changes from the original soft state to a shrinking state (with a small degree of shrinkage). Since the threaded connection has self-locking properties, the threaded nuts 5 will be in a locked state after being threaded with the first lead screw section 6 and the second lead screw section 9.

[0049] When the concrete structure is cured, its volume will shrink to a certain extent, and the template will adhere to the surface of the concrete structure. Since the clamping arm 4 is in a fixed state, the distance between the clamping arm 4 and the template will change, resulting in a gap between the surface of the clamping arm 4 and the surface of the template. Under the elastic resistance of the spring 21, the detection slider 1 moves into the gap. When the detection slider 1 moves, the sliding rod 22 moves synchronously, causing the rack part 19 to mesh with the gear part, thereby driving the swing part 16 to swing. In this way, the swing plate 15 swings synchronously, and the swing angle of the swing plate 15 is large, so that even when the movement stroke of the detection slider 1 is small, the swing plate 15 can also produce a certain degree of swing. The staff records the scale line corresponding to the stopping position of the swing plate 15 before and after reinforcement. When the span between the scale lines of the two states is large, it can be determined that the concrete has been cured in place.
