Description

Technical Field

[0001] This utility model belongs to the field of building formwork technology, and in particular relates to a reinforcement device for arc-shaped beam formwork. Background Technology

[0002] Curved beam formwork is a type of formwork used to shape curved beams. It can be made into a semi-circle or semi-arc shape according to the needs of the project. This type of formwork plays a key role in the construction process because it can ensure that the concrete forms the required curved structure after pouring. Curved beam formwork is usually composed of multiple parts, including plywood on the beam sides, angle steel, reinforcing plywood, vertical back ribs, horizontal back ribs, and tie rods, etc.

[0003] Chinese Patent Publication No. CN218715100U discloses a reinforcing device for an arc-shaped beam template, including a template base plate, two template side plates on the top of the template base plate, and positioning inserts fixedly connected to the bottom of each of the two template side plates. Two positioning slots are opened inside the template base plate. The device has a limiting insert that can be movably inserted into the interior of the positioning insert. The arc-shaped beam template reinforcing device clamps and fixes the arc-shaped beam in one piece. Thus, the entire arc-shaped beam can be clamped and fixed through multiple reinforcing devices, and elastic support can be achieved for the sleeve rod to prevent it from falling off during the hanging of the sleeve plate.

[0004] However, the above structure still has shortcomings. The structure uses a positioning plate fixed at the bottom of the side plate to be inserted into a positioning groove opened on the bottom plate. Therefore, when removing the side plate from the bottom plate, the positioning plate needs to be pulled out of the positioning groove first. However, after the concrete of the arc beam formwork composed of the bottom plate and the side plate is poured and solidified, the concrete and the side plate are directly and firmly bonded together, resulting in high frictional resistance. This makes it impossible to remove the positioning plate from the positioning groove. When using tools to pry the side plate off the side of the arc beam, it will be limited by the positioning plate, making the formwork disassembly inconvenient.

[0005] Therefore, it is necessary to provide a new type of curved beam formwork reinforcement device to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a curved beam formwork reinforcement device that can effectively reinforce and connect the bottom plate and side plate of the formwork and is easy to disassemble.

[0007] To solve the above technical problems, the arc beam formwork reinforcement device provided by this utility model includes: a support plate, two side plates are provided on the support plate, two reinforcing rods are installed on the side plates, a fixing block is fixedly installed on the reinforcing rod, and a reinforcement mechanism and a pin mechanism are provided on the support plate;

[0008] The reinforcement mechanism includes four first connecting blocks, which are fixedly installed on the bottom of the support plate. A support rod is fixedly connected between two first connecting blocks. A support slider is slidably installed on the support rod. An adjusting block is fixedly connected between two support sliders. A positioning block is fixedly installed on the support slider. Four second connecting blocks are fixedly installed on the bottom of the support plate. A bidirectional screw is rotatably installed on the second connecting blocks. The bidirectional screw passes through the adjusting block and is threadedly connected to the adjusting block. A first conical wheel is fixedly installed at one end of the bidirectional screw.

[0009] As a further embodiment of this utility model, the pin mechanism includes four mounting blocks, which are fixedly mounted on a support plate. A hollow tube is fixedly mounted on the mounting block, and a rod is slidably mounted inside the hollow tube. An annular baffle is fixedly sleeved on the rod, and a spring is sleeved on the rod. Both the spring and the annular baffle are located inside the hollow tube. A limiting hole is provided on the fixing block, and the rod is adapted to the limiting hole.

[0010] As a further embodiment of this utility model, one end of the insertion rod is provided with a bend.

[0011] As a further embodiment of this utility model, a rotating shaft is rotatably mounted on the bottom of the support plate, and a second conical wheel is fixedly sleeved on the rotating shaft. The second conical wheel meshes with the first conical wheel, and a handwheel is fixedly mounted on one end of the rotating shaft.

[0012] As a further embodiment of this utility model, a plurality of circular protrusions are fixedly installed on the handwheel, and the plurality of circular protrusions are distributed in a circumferential manner around the handwheel.

[0013] As a further embodiment of this utility model, two fixing screws are threadedly installed on the reinforcing rod, and one end of the fixing screw extends into the side plate and is threadedly connected to the side plate.

[0014] Compared with related technologies, the arc-shaped beam formwork reinforcement device provided by this utility model has the following beneficial effects:

[0015] 1. This utility model, by providing a reinforcement mechanism, allows two adjusting blocks to move toward each other via a bidirectional screw. The adjusting blocks then drive the support slider and positioning block to move. After the two positioning blocks merge together, a positioning insertion hole is formed in the middle. The reinforcement rod is then inserted into the positioning insertion hole and then into the limiting hole on the fixing block to achieve positioning and locking of the reinforcement rod. Therefore, the connection between the support plate and the side plate is effectively reinforced.

[0016] 2. After concrete is poured and formed by setting up a template consisting of a support plate and a side plate, the two positioning blocks can be adjusted to move in opposite directions, and one end of the insertion rod can be moved out of the limiting hole. This releases the limiting and obstruction of the reinforcing rod, making it easier to pry the side plate open from one side of the arc beam, effectively improving the disassembly effect of the template after use.

[0023] Please refer to the following: Figures 1 to 4 ,in, Figure 1 This is a first three-dimensional structural schematic diagram of the arc-shaped beam formwork reinforcement device of this utility model; Figure 2 A second three-dimensional structural schematic diagram of the arc-shaped beam template reinforcement device provided by this utility model; Figure 3 A schematic diagram of the bidirectional screw, first conical wheel, second conical wheel, and handwheel structure of the arc beam template reinforcement device provided by this utility model;

[0024] Figure 4A schematic diagram of the pin mechanism structure of the arc beam formwork reinforcement device provided by this utility model. The arc beam formwork reinforcement device includes: a support plate 1, two side plates 2 are provided on the support plate 1, two reinforcing rods 201 are installed on the side plates 2, and a fixing block 202 is fixedly installed on the reinforcing rods 201. The support plate 1 is provided with a reinforcement mechanism and a pin mechanism.

[0025] The reinforcement mechanism includes four first connecting blocks 3, which are fixedly installed on the bottom of the support plate 1. A support rod 301 is fixedly connected between two first connecting blocks 3. A support slider 302 is slidably installed on the support rod 301. An adjusting block 303 is fixedly connected between two support sliders 302. A positioning block 304 is fixedly installed on the support slider 302. Four second connecting blocks 4 are fixedly installed at the bottom of the support plate 1. A bidirectional screw 401 is rotatably installed on the second connecting block 4. The bidirectional screw 401 passes through the adjusting block 303 and is threadedly connected to the adjusting block 303. A first conical wheel 402 is fixedly installed at one end of the bidirectional screw 401.

[0026] like Figure 4 As shown, the pin mechanism includes four mounting blocks 5, which are fixedly mounted on the support plate 1. A hollow tube 501 is fixedly mounted on the mounting block 5, and a plug rod 502 is slidably mounted inside the hollow tube 501. An annular baffle 503 is fixedly sleeved on the plug rod 502, and a spring 504 is sleeved on the plug rod 502. Both the spring 504 and the annular baffle 503 are located inside the hollow tube 501. A limiting hole is provided on the fixing block 202, and the plug rod 502 is adapted to the limiting hole.

[0027] After the insertion rod 502 is moved, one end of the insertion rod 502 can be inserted into the limiting hole on the fixing block 202. Then, the spring force of the spring 504 pushes against the annular baffle 503, and the annular baffle 503 pushes against the insertion rod 502 to prevent it from loosening. Therefore, one end of the insertion rod 502 is limited in the limiting hole, which improves the fixing effect on the reinforcing rod 201.

[0028] like Figure 4 As shown, one end of the insertion rod 502 is bent;

[0029] Because one end of the insertion rod 502 is bent, the bent part can be held by hand when the insertion rod 502 is moved, making the operation more convenient.

[0030] like Figure 2 and Figure 3As shown, a rotating shaft 403 is rotatably mounted on the bottom of the support plate 1, and a second conical wheel 404 is fixedly sleeved on the rotating shaft 403. The second conical wheel 404 meshes with the first conical wheel 402, and a handwheel 405 is fixedly mounted on one end of the rotating shaft 403.

[0031] By turning the handwheel 405, the handwheel 405 can control the rotation of the shaft 403, which in turn drives the second conical wheel 404 to rotate. The first conical wheel 402, which meshes with the second conical wheel 404, is then driven to rotate, thereby achieving the transmission of kinetic energy.

[0032] like Figure 3 As shown, a plurality of circular protrusions are fixedly installed on the handwheel 405, and the plurality of circular protrusions are distributed in a circumferential manner around the handwheel 405;

[0033] The handwheel 405 has a circular protrusion, which increases the frictional resistance between the hand and the palm when the hand rotates the handwheel 405, thereby improving the rotation efficiency of the handwheel 405.

[0034] like Figure 1 As shown, two fixing screws 203 are threadedly installed on the reinforcing rod 201, and one end of the fixing screw 203 extends into the side plate 2 and is threadedly connected to the side plate 2.

[0035] By providing a fixing screw 203, the reinforcing rod 201 can be fixedly connected to the side plate 2, which facilitates the assembly and fixing of the side plate 2 and the support plate 1. At the same time, if the reinforcing rod 201 is damaged, the reinforcing rod 201 can be disassembled and replaced.

[0036] The working principle of the arc-shaped beam formwork reinforcement device provided by this utility model is as follows:

[0037] First step: First, fix the reinforcing rod 201 on the side of the side plate 2. Then, rotate the handwheel 405 to drive the rotating shaft 403 to rotate. The rotating shaft 403 then drives the second conical wheel 404 to rotate. The first conical wheel 402, which meshes with the second conical wheel 404, can be driven to rotate. Then, the first conical wheel 402 drives the double screw 401 to rotate. Then, the double screw 401 drives the two adjusting blocks 303 to move towards each other. Then, the adjusting blocks 303 drive the support slider 302 to move. The support slider 302 then drives the positioning block 304 to move. Thus, the two positioning blocks 304 move closer to each other and merge, forming a positioning hole between the two positioning blocks 304. Then, the reinforcing rod 201 is vertically inserted into the positioning hole. Then, one end of the insertion rod 502 is horizontally inserted into the limiting hole on the fixing block 202. Thus, the vertical and horizontal movement of the reinforcing rod 201 is limited, so that the support plate 1 and the side plate 2 are effectively reinforced and connected.

[0038] The second step: After the concrete is poured and formed on the arc beam formwork composed of the support plate 1 and the side plate 2, when the formwork needs to be disassembled, first adjust the two adjusting blocks 303 to move in opposite directions by rotating the double screw 401. Then, the adjusting block 303 drives the positioning block 304 to move away from one side of the reinforcing rod 201. At the same time, one end of the insertion rod 502 is moved out of the limiting hole on the fixing block 202, thereby releasing the limiting effect on the reinforcing rod 201. Then, when disassembling the side plate 2, it will not be blocked by the positioning block 304, making it easy to pry open the side plate 2 and making the formwork disassembly convenient.
