A type of jig for positioning and installing reinforcing bars

Abstract

A rebar installation and positioning formwork fixture, belonging to the construction field, addresses the problem of multiple holes being designed to accommodate rebars with different spacings. This results in some holes being unprotected during rebar insertion, allowing concrete to flow into and block the holes, necessitating subsequent cleaning – a very troublesome issue. The rebar installation and positioning formwork fixture includes a base, rollers positioned below the base, a first steel template hinged to one side of the base, and a hydraulic cylinder fixedly connected to the center of the base. A rotating mechanism drives limiting cylinders back and forth, moving the desired limiting cylinders to the inside of the second steel template and the unwanted limiting cylinders to the outside, thereby reducing the likelihood of concrete blocking the limiting cylinders.

Description

Technical Field

[0001] This invention relates to the field of construction, and in particular to a formwork fixture for positioning and installing reinforcing bars. Background Technology

[0002] The rebar installation positioning jig is a casting model used to position the rebar during the pouring of concrete for wall hangings. Its main purpose is to limit the position of the concrete and rebar.

[0003] The announcement number CN206383282U discloses a precast T-beam ribbed steel reinforcement skeleton formwork, which effectively solves the problems of uneven horizontal and vertical spacing of steel reinforcement and poor steel reinforcement positioning. The ribbed steel reinforcement skeleton formwork of this utility model includes a ribbed steel reinforcement binding platform. Existing formwork mainly uses holes set in the crossbeam to fix the steel reinforcement, through which the steel reinforcement is passed. To accommodate steel reinforcement with different spacing, multiple holes are set. This results in some holes having no reinforcement to block the inside when the steel reinforcement is inserted, allowing concrete to flow into and block the holes, requiring cleaning later, which is very troublesome.

The first guide rod 506 does not rotate when moving inside the first guide groove 505. The lower end of the first guide rod 506 is fixedly connected to the second guide rod 507. The guide hole 504 has an inclined straight-line shape, and the inner side of the guide hole 504 is in contact with the outer surface of the second guide rod 507. The second guide rod 507 has a cylindrical shape, so that when the guide hole 504 moves up and down, it can drive the second guide rod 507 and the first guide rod 506 to move along the trajectory of the first guide groove 505.

The lower surface of the second steel template 509 is in contact with the upper surface of the first steel template 3, so that the second steel template 509 blocks the unfilled concrete.

[0022] The sliding assembly 61 includes a second fixed plate 6101 fixedly connected to one end of the first steel template 3. A second threaded rod 6102 is threadedly connected to the inner side of the second fixed plate 6101, and a first connecting plate 6103 is rotatably connected to the outer side of the second threaded rod 6102.

A second guide groove 61 is provided on the inner side of the second push plate 6107. 08. A third guide rod 6109 is provided on the inner side of the second guide groove 6108. A support cylinder 6110 is fixedly connected to the outer side of the second steel template 509. A first hole 6111 is provided inside the second steel template 509. A second hole 6112 is provided on the inner side of the support cylinder 6110. A limiting cylinder 6113 is provided on the inner side of the second hole 6112. The limiting cylinder 6113 is connected to the third guide rod 6109 by rotation. A second recess is provided on the inner side of the limiting cylinder 6113. The central axis of the groove 6114, the second hole 6112 and the first hole 6111 are on the same central axis, and the inner side of the second hole 6112 fits against the outer side of the limiting cylinder 6113, so that the limiting cylinder 6113 can rotate inside the second hole 6112. The second guide groove 6108 is composed of a horizontal straight groove and an inclined straight groove, and they are interconnected, so that the third guide rod 6109 can move back and forth along the trajectory of the second guide groove 6108.

[0023] A third guide groove 7 is provided on the inner wall of the first hole 6111 near the second push plate 6107. The guide assembly 62 includes a fourth guide rod 6201 disposed inside the third guide groove 7. A third groove 6202 is provided on the inner wall of the first hole 6111 away from the second push plate 6107. An elastic rubber pad 6203 is disposed inside the third groove 6202. A baffle 6204 is fixedly connected to the lower end of the elastic rubber pad 6203. The outer side of the baffle 6204 fits against the inner side of the third groove 6202, and the lower end face of the baffle 6204 is an inclined surface. The appearance structure of the third guide groove 7 is spiral. The third guide groove 7 and the fourth guide rod 6201 are fitted with a clearance fit. The fourth guide rod 6201 and the limiting cylinder 6113 are fixedly connected, so that when the fourth guide rod 6201 moves inside the third guide groove 7, it can drive the limiting cylinder 6113 to rotate along the trajectory of the third guide groove 7.

[0024] When fixing the reinforcing bars, the unnecessary limiting cylinder 6113 needs to be moved to the outside of the second steel formwork 509 to reduce the possibility of concrete blocking the limiting cylinder 6113. The specific operation is as follows: Rotating the second threaded rod 6102 causes the first connecting plate 6103 to move upward, which in turn causes the second connecting plate 6105, located inside the first groove 6104, to move upward, and the third connecting plate 6106 and the second push plate 6107 to move upward. This, in turn, causes the second guide groove 6108, located inside the second push plate 6107, to move upward. Since the second guide groove 6108 consists of horizontal and inclined straight grooves that are interconnected, when the third guide rod 6109 moves inside the inclined straight groove of the second guide groove 6108, it causes the third guide rod 6109 to move back and forth, thus causing the limiting cylinder 6113 to move back and forth along the trajectory of the second hole 6112. When the limiting cylinder 6113 moves towards the inside of the second steel template 509, it pushes the baffle 6204 along the inclined side of the baffle 6204 towards the inside of the third groove 6202, thus opening the first hole 6111. When the limiting cylinder 6113 moves out of the inside of the first hole 6111, the baffle 6204 is limited by the elastic rubber pad 6203, preventing the elastic rubber pad 6203 from flowing outward. The second guide grooves 6108 on the multiple second push plates 6107 are designed according to the required gap of the limiting cylinder 6113. When the unnecessary limiting cylinder 6113 moves to the outside of the second steel template 509, the concrete is blocked, reducing the outflow of concrete and reducing the possibility of concrete blocking the limiting cylinder 6113.

[0025] After adjusting the spacing, place the reinforcing bars inside the corresponding limiting cylinder 6113. Rotate the first threaded rod 502 to drive the first push plate 503 downward, which in turn drives the guide hole 504 downward, pushing the first guide rod 506 and the second guide rod 507 along the trajectory of the first guide groove 505 towards the center. This causes the first connecting rod 508 and the second steel template 509 to move towards the center, thus limiting the reinforcing bars that need to be limited when the limiting cylinder 6113 moves towards the center. Activate the hydraulic cylinder 4 to rotate the first steel template 3 and the second steel template 509 to fit against the wall of the foundation pit, pushing the inner side of the first steel template 3 and the second steel template 509 to pour concrete. The concrete will be guided along the reinforcing bars into the inner side of the limiting cylinder 6113. After the concrete dries, the inner side of the limiting cylinder 6113 will be fixedly connected to the concrete and difficult to disassemble. To reduce the degree of connection, the specific operation is as follows: The second threaded rod 6102 is manually rotated at regular intervals, causing the first connecting plate 6103 to move left and right. This causes the second connecting plate 6105 and the third connecting plate 6106 to move left and right, which in turn causes the second push plate 6107 to move left and right, and the second guide groove 6108 to move left and right. This pushes the third guide rod 6109 and the limiting cylinder 6113, which is rotatably connected to the third guide rod 6109, to move back and forth. Since the fourth guide rod 6201 is fixedly connected to the limiting cylinder 6113, the fourth guide rod 6201 drives the limiting cylinder 6113 to rotate along the trajectory of the third guide groove 7. This allows the limiting cylinder 6113 to rotate and move back and forth, reducing the need to clean the concrete stuck together inside the limiting cylinder 6113.

[0026] When fixing the reinforcing bars, the ends of the reinforcing bars need to be exposed on the outside for easy fixing. However, after the reinforcing bars are fixed, they cannot remain exposed on the outside. The mold needs to be used again for pouring. When the limiting cylinder 6113 is rotated and pulled to prevent it from sticking to the concrete, the concrete is in a semi-solid state. The limiting cylinder 6113 will drive part of the concrete to rotate and rub against the undriven concrete to create grooves. This will increase the contact area when pouring next time, making the pouring more solid.
