Description

Technical Field

[0001] The invention belongs to the technical field of construction equipment, and specifically provides a steel bar template positioning construction structure in a reinforced concrete component. Background Art

[0002] Rebar formwork refers to the formwork used to form newly poured concrete and the formwork that supports the steel bars inside the poured concrete. The structural part that contacts the concrete and controls the predetermined size, shape, and position is called the mold. The rods, trusses, connectors, metal accessories, working trestles, etc. that support and fix the formwork constitute the supporting system.

[0003] When using existing steel formwork, the concrete is easily adhered to the steel formwork after pouring, which makes it inconvenient to remove the concrete component from the steel formwork, reducing its practicality; at the same time, the existing steel formwork cannot effectively fix the steel bars inside the concrete, making it easy to knock down the steel bars when pouring concrete, which in turn leads to a low bearing capacity of the formed reinforced concrete component, seriously affecting its stability after use.

[0004] Accordingly, the art requires a steel bar formwork positioning construction structure in reinforced concrete components to solve the above problems. Summary of the Invention

[0005] The present invention proposes a steel bar template positioning construction structure in a reinforced concrete component, which solves the problems in the prior art that the steel bar template is difficult to demould from the concrete component and the steel bar template cannot fix the steel bars inside the concrete component.

[0006] The technical solution of the present invention is achieved as follows: a steel bar formwork positioning construction structure in a reinforced concrete member comprises a bottom plate and a first support plate and a second support plate vertically arranged on the bottom plate, a mold and a mounting plate are arranged between the first support plate and the second support plate, the mold is fixedly connected to the first support plate through a first connecting plate and fixedly connected to the second support plate through a second connecting plate, a top formwork and a bottom formwork are respectively arranged on the top and bottom of the mold, a pouring port is arranged on the top formwork, the top formwork is vertically slidably connected to the first support plate, the bottom formwork is vertically slidably connected to the second support plate, and the mounting plate is located at the top formwork. The top of the first slide bar passes through the second connecting plate and is fixedly connected to the second gear plate, and the bottom passes through the bottom template and is fixedly connected to the first stopper. The first gear plate and the second gear plate are located on both sides of the gear and mesh with each other. A first spring is sleeved on the first slide bar, and the first spring is located between the second connecting plate and the bottom template and is fixedly connected to the two. When the bottom template contacts the mold, the first spring is in a compressed state.

[0007] The technical effect of this solution is that the driving motor drives the gear to rotate, and the gear drives the top template and the bottom template to cooperate with each other through the first tooth plate and the second tooth plate, which can effectively clamp the steel bars in the concrete component up and down, and prevent the steel bars from being knocked down during concrete pouring and affecting the molding quality of the concrete component; after pouring is completed, the top template moves upward and leaves the concrete component through the driving motor, and the first tooth plate and the second tooth plate cooperate to operate, so that the first slide bar moves downward to separate the first stopper at its bottom end from the restriction on the bottom template, and the bottom template has a tendency to separate from the concrete component under the elastic force of the first spring, and then the bottom template can be separated from the concrete component by simply knocking or shaking the bottom template downward. The arrangement of this device not only fixes the steel bars in the concrete component, but also makes it easy for the formed concrete component to separate from the top template and the bottom template, effectively avoiding damage to the concrete component, and also making it convenient for the device to be quickly put into next use.

[0008] The top of the second stop is fixedly provided with a third tooth plate extending along the vertical direction, and the top of the second stop is fixedly provided with a third tooth plate extending along the vertical direction, and a sliding hole is opened in the cross plate, and the second slide rod passes through the sliding hole and is fixedly connected to the baffle at the upper and lower sides of the cross plate respectively. A second spring is sleeved on the second slide rod, and the two ends of the second spring are fixedly connected to the bottom formwork and the cross plate respectively. A knocking block is provided on the upper surface of the cross plate, and the bottom of the top formwork is fixedly connected to the third slide rod, the third slide rod passes through the first connecting plate and is connected to the third stop, and the side of the third stop close to the cross plate is fixedly connected to the third tooth plate extending along the vertical direction, and a protrusion is provided on the cross plate, and the protrusion cooperates with the teeth on the third tooth plate.

[0009] The technical effect of this solution is that when the concrete component is dried and formed and needs to be demolded, the drive motor is started, and the first tooth plate and the second tooth plate cooperate to move the first tooth plate and the first slide rod in opposite directions. At this time, under the action of the third tooth plate, the protrusion, the sliding hole and the second spring, the knocking block on the horizontal plate repeatedly knocks and vibrates the bottom surface of the bottom template, effectively breaking the bonding between the bottom template and the bottom surface of the concrete component. Then, under the force of the first spring, the bottom template slowly breaks away from contact with the concrete component and the mold, which facilitates demolding and further avoids damage to the concrete component.

[0010] In the preferred technical solution of the steel bar formwork positioning construction structure in the above-mentioned reinforced concrete components, the mold includes a side formwork, a card slot is provided at the bottom of the side formwork, and a card strip adapted to the card slot is provided on the upper surface of the bottom formwork. When the bottom formwork and the side formwork are fitted together, the card strip is inserted into the card slot.

[0011] The technical effect of this solution is that the card strips and the card slots cooperate to prevent concrete from overflowing from the gap between the bottom formwork and the side formwork during concrete pouring, thereby ensuring the molding quality of the concrete components.

[0012] In the preferred technical solution of the steel bar formwork positioning construction structure in the above-mentioned reinforced concrete member, a flexible cushion layer is provided on the lower surface of the top formwork.

[0013] The technical effect of this solution is: by setting up a flexible cushion layer, when the top formwork moves downward to squeeze the steel bars in the concrete component, the top of the steel bars can squeeze the flexible cushion layer to cause it to deform, so that the steel bars are fixed more firmly and avoid being knocked down when pouring concrete.

[0014] In the preferred technical solution of the steel formwork positioning construction structure in the above-mentioned reinforced concrete components, the pouring port of the top formwork is provided with a pouring funnel, which includes a cylindrical portion and a reducing portion connected to each other, the cylindrical portion is located above the reducing portion, and the diameter of the reducing portion close to the cylindrical portion is greater than its diameter away from the cylindrical portion.

[0015] The technical effect of this solution is: by setting a pouring funnel, it is convenient to pour concrete into the mold and avoid concrete splashing.

[0016] In the preferred technical solution of the steel bar formwork positioning construction structure in the above-mentioned reinforced concrete components, a fixing plate arranged in the horizontal direction is fixedly connected to one side of the mounting plate, the driving motor is fixed on the fixing plate, the output shaft of the driving motor passes through the mounting plate and is fixedly connected to the gear, and the output shaft of the driving motor is fixedly connected to retaining rings on both sides of the mounting plate.

[0028] The mounting plate 3 is located above the top template 4 and is fixedly connected to the first support plate 11 and the second support plate 12. The rear side of the mounting plate 3 is fixedly connected to a fixing plate 31 arranged in a horizontal direction. A driving motor 32 is installed on the fixing plate 31. The output shaft of the driving motor 32 passes through the mounting plate 3 and is connected to a gear 33. The output shaft of the driving motor 32 is fixedly connected to retaining rings 34 on both sides of the mounting plate 3.

[0029] A first toothed plate 42, extending vertically, is fixedly connected to the right end of the top plate 4. A first slide bar 51, extending vertically, is inserted through the right side of the mold 2 through the bottom plate 5. The top of the first slide bar 51 passes through the second connecting plate 22 and is fixedly connected to the second toothed plate 52, extending vertically. The bottom of the first slide bar 51 passes through the bottom plate 5 and is fixedly connected to the first stopper 53. The first and second toothed plates 42, 52 are located on either side of the gear 33 and mesh with it. A first spring 54 is sleeved on the first slide bar 51. The first spring 54 is located between the second connecting plate 22 and the bottom plate 5 and is fixedly connected to both. When the bottom plate 5 contacts the mold 2, the first spring 54 is compressed, and the first stopper 53 abuts against the lower surface of the bottom plate 5.

[0030] like Figure 3 and Figure 4As shown, a horizontal plate 6 is provided below the bottom template 5, and two second slide bars 61 extending vertically are passed through the horizontal plate 6. The tops of the two second slide bars 61 pass through the bottom template 5 and are fixedly connected to the second stopper 62. The two second slide bars 61 are located on the left and right sides of the mold 2. A sliding hole 63 is provided on the horizontal plate 6. The sliding hole 63 is a long hole in the left and right directions. The second slide bar 61 passes through the sliding hole 63 and is fixedly connected to a baffle 64 on the upper and lower sides of the horizontal plate 6 respectively. The size of the baffle 64 is larger than the size of the sliding hole 63. A second spring 65 is sleeved on the second slide bar 61. The two ends of the second spring 65 are fixedly connected to the bottom template 5 and the horizontal plate 6 respectively. A plurality of knocking blocks 66 are evenly distributed on the upper surface of the horizontal plate 6.

[0031] The bottom of the top template 4 is fixedly connected to a third slide rod 43, the third slide rod 43 passes through the first connecting plate 21 and is connected to a third stopper 44, and the third stopper 44 is fixedly connected to a third tooth plate 45 extending vertically on one side close to the horizontal plate 6, and a protrusion 67 is provided on the horizontal plate 6, which cooperates with the teeth on the third tooth plate 45, and a through hole is opened on the second connecting plate 22 for the third tooth plate 45 to pass through.

[0032] In this embodiment, the mold 2 includes a side template, a card slot is provided at the bottom of the side template, and a card strip adapted to the card slot is provided on the upper surface of the bottom template 5. When the bottom template 5 is fitted with the side template, the card strip is inserted into the card slot to prevent concrete from overflowing from the gap between the bottom template 5 and the side template during concrete pouring, thereby ensuring the molding quality of the concrete component.

[0033] In this embodiment, a flexible cushion layer 46 is provided on the lower surface of the top formwork 4. When the top formwork 4 moves downward to squeeze the steel bars in the concrete member, the tops of the steel bars can squeeze the flexible cushion layer 46, causing it to deform, thereby more firmly fixing the steel bars and preventing them from being knocked over during concrete pouring. As an example, the flexible cushion layer 46 is a rubber cushion layer.

[0034] When in use, the drive motor 32 is started to drive the gear 33 to rotate counterclockwise. The gear 33 drives the top template 4 and the bottom template 5 to move downward and upward respectively through the first tooth plate 42 and the second tooth plate 52, until the top template 4 presses the steel bars in the concrete component and the upper surface of the bottom template 5 is tightly fitted with the side template of the mold 2, effectively clamping and fixing the steel bars in the concrete component up and down, avoiding the steel bars being knocked down during concrete pouring and affecting the molding quality of the concrete component; pour the mixed concrete into the pouring funnel 41 on the top template 4, and the concrete enters the mold 2 for pouring.

[0035] After pouring is completed and the concrete is dried and formed and needs to be demoulded, the driving motor 32 is started to make the driving gear 33 rotate clockwise, and the gear 33 drives the top template 4 to move upward through the first tooth plate 42 and the second tooth plate 52 to break away from the extrusion of the concrete member steel bars, and drives the first sliding rod 51 to move downward so that the first stopper 53 at its bottom end breaks away from the extrusion of the bottom template 5. At this time, since the bottom template 5 and the bottom surface of the concrete member are in a bonded state, the bottom template 5 remains stationary after breaking away from the extrusion of the first stopper 53; as the top template 4 moves upward, the third sliding rod 43 at the bottom of the top template 4 drives the third tooth plate 45 to move upward, and the teeth on the third tooth plate 45 drive the cross plate 6 to move upward by the upward extrusion protrusion 67, so that the knocking block 66 on the upper surface of the cross plate 6 knocks the lower surface of the bottom template 5, and the knocking block on the cross plate 6 After the block 66 contacts the bottom template 5, the cross plate 6 can no longer rise, and the teeth on the third tooth plate 45 push the protrusion 67 and the cross plate 6 to slide to the right. After the teeth on the third tooth plate 45 slide over the protrusion 67, under the elastic force of the second spring 65, the protrusion 67 and the cross plate 6 are reset, so that the protrusion 67 contacts the next tooth on the third tooth plate 45. As the third tooth plate 45 continues to rise, the knocking block 66 repeatedly knocks and vibrates the bottom template 5, so that the bonding between the bottom template 5 and the concrete component is broken; after the bonding between the bottom template 5 and the concrete component is broken, under the elastic force of the first spring 54, it moves downward to break away from the contact with the concrete component and the side template of the mold 2; after the bottom template 5 moves downward to a certain distance, the operation of the drive motor 32 is stopped, and the concrete component can be demoulded from the mold 2 by the existing technology.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
