Abstract
Description
Technical Field
[0001] This utility model relates to the field of precast concrete components, and in particular to an auxiliary shaping device for internal reinforcing bars in precast concrete components. Background Technology
[0002] Precast concrete components are building components made in a factory using concrete as the basic material. They include beams, slabs, columns, and architectural finishing accessories.
[0003] The utility model disclosed in the existing announcement number CN213412427U is an auxiliary shaping device for internal steel bars of precast concrete components, belonging to the technical field of precast concrete components. It includes a baffle and two sets of baffles. Two sets of baffles are integrally provided on one side of the baffle. The surface openings of the two sets of baffles are provided with grooves. Sliding grooves are embedded in the inside of the grooves. The lower end of the grooves is provided with a groove bottom plate. Limiting blocks are provided in mutual fitting inside the grooves. The surface openings of the baffles are provided with two sets of grooves A. The lower end of the two sets of grooves A is provided with a connecting plate.
[0004] In actual use, the groove and the limiting block move in a straight up-down motion. This causes a lot of friction between the groove and the limiting block. When fine sand enters the groove, it further increases the friction between the groove and the limiting block, making demolding difficult and inconvenient.
[0005] Therefore, we propose an auxiliary shaping device for the internal reinforcing bars of precast concrete components. Utility Model Content
[0006] In view of the shortcomings of the prior art, this utility model provides an auxiliary shaping device for the internal steel bars of precast concrete components, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary shaping device for internal reinforcing bars of precast concrete components, comprising a mold, wherein groove 1 and groove 2 are respectively formed around the outer wall of the mold, both groove 1 and groove 2 being trapezoidal in shape, and groove 2 being deeper than groove 1; a shaping component is provided inside each groove 1 and groove 2, the shaping component including limiting block 1, limiting block 2 and limiting block 3, all of which are installed inside groove 1; sliders are fixedly connected to both sides of the outer wall of limiting block 1, limiting block 2 and limiting block 3; and a groove for cooperating with the slider is formed inside each groove. The upper surface of the limiting block three is provided with an arc-shaped groove one, the lower surface of the limiting block two is provided with an arc-shaped groove two that works with the arc-shaped groove one, the upper surface of the limiting block two is provided with an arc-shaped groove three, and the lower surface of the limiting block one is provided with an arc-shaped groove four that works with the arc-shaped groove three. Each of the limiting blocks one, two, and three has a longitudinally formed circular hole inside. A circular rod is installed inside each of the circular holes. A hexagonal head is fixedly connected to the top of the circular rod. A downward thread is formed in the lower middle part of the outer wall of the circular rod. The diameter of the hole formed between the arc-shaped grooves one, two, three, and four is adapted to the thickness of the reinforcing bar. A demolding assembly is provided on the outer wall of the circular rod.
[0008] Place limiting block one, limiting block two, and limiting block three into groove one and groove two. The arc groove between the multiple limiting blocks forms a round hole that matches the diameter of the reinforcing bar. Insert the reinforcing bar horizontally and vertically into the round hole. At this time, insert the round rod into the round hole opened inside the multiple limiting blocks. Rotate the round rod. Since the lower thread on the outer wall of the round rod matches the inner thread of the round of limiting block three, the hexagonal head locks the multiple limiting blocks together, preventing cement from flowing out along the gap. By designing the groove on the side of the mold as a trapezoid, the friction between the limiting block and the mold is effectively reduced, making the mold easier and more convenient to demold in the future.
[0009] As a preferred embodiment of this utility model, the demolding assembly includes an upper thread, which is formed in the upper middle part of the outer wall of the circular rod, and a nut is threadedly connected to the outer wall of the upper thread.
[0010] By threading the outer wall of the circular rod and using nuts to lock multiple limit blocks, the circular rod and hexagonal head have a certain amount of room to move. When the circular rod is turned, the end of the circular rod contacts the mold surface, generating a thrust that pushes the multiple limit blocks upward. At this time, the solidified concrete component also moves, thus achieving the demolding effect.
[0011] The beneficial effects of this utility model are as follows: by designing the grooves one and two on the side of the mold and multiple limiting blocks into trapezoidal shapes, the friction between the limiting blocks and the mold is effectively reduced. Furthermore, the trapezoidal blocks disengage from the grooves during movement, making subsequent demolding of the mold easier and more convenient. At the same time, the upper and lower threads on the outer wall of the circular rod can reduce the rotation time of the screw and improve the efficiency of the device during use.
[0012] This invention uses threads on the outer wall of a circular rod, which, together with a nut, locks multiple limiting blocks in place. At this point, the circular rod and the hexagonal head have some room to move. As the circular rod is turned, the end of the rod contacts the surface of the mold, generating a thrust that pushes the multiple limiting blocks upward. The solidified concrete component also moves accordingly, thus achieving the demolding effect. Attached Figure Description

[0018] 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.
[0019] Example 1
[0020] Please see Figures 1 to 4A device for auxiliary shaping of internal reinforcing bars in precast concrete components includes a mold 1. The outer wall of the mold 1 has two grooves, a first groove 2 and a second groove 3, respectively. Both grooves are trapezoidal in shape, with the second groove 3 being deeper than the first groove 2. Each groove 2 and groove 3 has a shaping component 4 inside. The shaping component 4 includes a limiting block 401, a limiting block 402, and a limiting block 403. These three blocks are installed inside the first groove 2. Slider blocks 7 are fixedly connected to both sides of the outer wall of each limiting block 401, 402, and 403. Each groove 2 has a groove 8 that cooperates with the slider 7 inside. The upper surface of the limiting block 403 has an arc-shaped groove 4. 04. The lower surface of the limiting block 2 402 is provided with an arc groove 2 405 that matches the arc groove 1 404. The upper surface of the limiting block 2 402 is provided with an arc groove 3 406. The lower surface of the limiting block 1 401 is provided with an arc groove 407 that matches the arc groove 3 406. The interiors of the limiting blocks 1 401, 2 402 and 3 403 are all provided with circular holes in the longitudinal direction. A circular rod 408 is installed inside the multiple circular holes. A hexagonal head 6 is fixedly connected to the top of the circular rod 408. The lower part of the outer wall of the circular rod 408 is provided with a thread 409. The diameter of the hole formed between the arc groove 1 404, arc groove 2 405, arc groove 3 406 and arc groove 407 is adapted to the thickness of the steel bar. The outer wall of the circular rod 408 is provided with a demolding component 5.
[0021] Limiting blocks 1 (401), 2 (402), and 3 (403) are placed in grooves 1 (2) and 2 (3). The arc-shaped grooves between the multiple limiting blocks form round holes that match the diameter of the reinforcing bars. The reinforcing bars are inserted horizontally and vertically into the round holes. At this time, a circular rod 408 is inserted into the round holes opened inside the multiple limiting blocks. The circular rod 408 is rotated. Since the lower thread 409 on the outer wall of the circular rod 408 matches the inner thread of the round hole of limiting block 3 (403), the hexagonal head 6 locks the multiple limiting blocks together, preventing cement from flowing out along the gaps. By designing grooves 1 (2) and 2 (3) on the side of mold 1 and the limiting blocks as trapezoids, the friction between the limiting blocks and mold 1 is effectively reduced, making it easier and more convenient to demold mold 1 in the future.
[0022] Please see Figure 1 and Figure 4 In this embodiment, the demolding component 5 includes an upper thread 501, which is formed in the upper middle part of the outer wall of the circular rod 408, and a nut 502 is threadedly connected to the outer wall of the upper thread 501.
[0023] By opening a thread 501 on the outer wall of the circular rod 408 and cooperating with the nut 502, multiple limiting blocks are locked. At this time, the circular rod 408 and the hexagonal head 6 have a certain amount of room to move. Continue to turn the circular rod 408, and the end of the circular rod 408 contacts the surface of the mold 1, generating a thrust to push the multiple limiting blocks upward. At this time, the solidified concrete component also moves, thereby achieving the demolding effect.
[0024] Working principle: Multiple limiting blocks are installed inside mold 1. The reinforcing bars are inserted horizontally and vertically into the circular holes formed between the limiting blocks and the arc-shaped grooves. At this time, the circular rod 408 is inserted into the circular holes opened inside the multiple limiting blocks. Rotating the circular rod 408, since the lower thread 409 on the outer wall of the circular rod 408 matches the inner thread of the circular hole 403 of the limiting block, and with the help of the hexagonal head 6, the multiple limiting blocks are locked together, preventing cement from flowing out along the gaps. By designing the groove on the side of mold 1 and the limiting blocks into a trapezoidal shape, the friction between the limiting blocks and mold 1 is effectively reduced, making it easier and more convenient to demold mold 1 in the future. The upper thread 501 is opened on the outer wall of the circular rod 408, and with the help of the nut 502, the multiple limiting blocks are locked. At this time, the circular rod 408 and the hexagonal head 6 have a certain amount of room for movement. Continue to turn the circular rod 408, and the end of the circular rod 408 contacts the surface of mold 1, generating a thrust to push the multiple limiting blocks upward. At this time, the solidified concrete component also moves, thereby achieving the demolding effect.
