Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering machinery, and in particular relates to a reinforcement production line for a prefabricated bottom plate of a large-span composite plate. Background Art

[0002] Composite slabs (i.e. composite floor slabs) are assembled integral slabs made of precast slabs and cast-in-place reinforced concrete layers. Composite slabs have good integrity, and the upper and lower surfaces of the slabs are flat, which is convenient for finishing layer decoration. They are suitable for high-rise buildings and large-span buildings that require high overall rigidity. Precast slabs are both one of the components of the floor structure and the permanent formwork of the cast-in-place reinforced concrete composite layer. Horizontal equipment pipelines can be laid in the cast-in-place composite layer.

[0003] However, due to the lack of corresponding steel bar bending equipment when making the cast-in-place prefabricated panels, workers can only use simple tools to perform the bending process. On the one hand, only a small part of the steel bar can be bent each time, which is extremely inefficient and increases labor costs. On the other hand, because it is not a one-time processing, the bending degree and size of each component are not uniform. When tying the cage later, it cannot be tied together or is very difficult, which is bound to delay some working hours. Therefore, in order to adapt to the current good trend of the development of prefabricated buildings, it is necessary to develop a relatively efficient reinforcement production line. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems and provide a reinforcement production line for prefabricated base plates of large-span composite slabs. The reinforcement production line can bend the steel bars into a continuous V-shape at one time with good consistency, which is convenient for subsequent reinforcement cage making and greatly improves efficiency.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a reinforcement production line for prefabricated base plates of large-span composite plates, including reinforcement making equipment, reinforcement welding device, and reinforcement tying platform, the reinforcement making equipment includes a machine body, movable splints are horizontally arranged on the machine body, the splints include a first splint and a second splint that are parallel to each other, and tie rods are arranged on the relatively close side walls of the first splint and the second splint, and the other side is connected to the machine body through a horizontally movable telescopic mechanism, one end of the tie rod is movably connected to the inner walls of the first splint and the second splint, respectively, and a locking mechanism is arranged at the other end; multiple tie rods on the first splint and multiple tie rods on the second splint are staggered and spaced, and one end of the two adjacent tie rods with the locking mechanism is hinged by a connecting rod of equal length; the cross-section of the reinforcement welding device is an inverted V-shaped welding frame; the reinforcement tying platform is square, and limit grooves are equidistantly arranged on the upper end of its periphery.

[0006] Furthermore, a sliding block is provided through each of the pull rods. The sliding block can move along the extension direction of the clamping plate, and a V-shaped groove is provided on one side of the sliding block close to the locking mechanism.

[0007] Furthermore, the slide block is provided with a latching tooth, and the body is provided with a sliding groove matching the latching tooth along the extending direction of the clamping plate.

[0008] Furthermore, the engaging mechanism is two vertically arranged limiting columns.

[0009] Furthermore, relatively close side walls of the first clamping plate and the second clamping plate are both provided with guide rail grooves along their extension direction, and one end of the pull rod away from the locking mechanism is provided with a roller matched with the guide rail groove.

[0010] Furthermore, the telescopic mechanism is an oil cylinder.

[0011] Furthermore, a guide assembly in the same direction as the oil cylinder is provided between the first clamping plate, the second clamping plate and the machine body.

[0012] Furthermore, both sides of the welding frame are provided with ribs.

[0013] Furthermore, a U-shaped holder is provided at the upper end of the welding frame.

[0014] Furthermore, the upper end opening of the limiting groove is arranged in a V shape.

[0015] The beneficial effects of the present invention are as follows: the reinforcement production line can bend the reinforcement into a continuous V-shape at one time, with good consistency, which is convenient for subsequent reinforcement cage making and greatly improves efficiency.

[0016] 1. In the present invention, when the pull rod shakes the steel bar, force is applied through the V-shaped groove to force the steel bar to form a relatively standard V-shape, thereby ensuring the consistency of the final product.

[0017] 2. The two limit columns in the present invention are cylindrical, the distance between them is slightly larger than the outer circle of the steel bar, the upper end is open, and the opening can be set in a V-shape, which is convenient for quickly placing the steel bar in the locking mechanism and convenient for taking out and putting in.

[0018] 3. In the present invention, the cooperation between the roller and the guide rail groove limits the movement of one end of the pull rod along the extension direction of the clamp plate, and the middle end of the pull rod on the second clamp plate is fixedly connected to limit the overall deviation.

[0019] 4. The reinforcement cage prepared by the present invention has good consistency, which is very convenient for workers to perform operations such as welding and tying, without the need for extra effort for correction, and the efficiency is significantly improved.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0033] like Figure 1-11As shown, the specific structure of the present invention is: a reinforcement production line for a prefabricated bottom plate of a large-span composite plate, including a reinforcement making equipment, a reinforcement welding device, and a reinforcement tying platform. The reinforcement making equipment includes a machine body 1, and the machine body 1 is horizontally provided with movable clamps 2, and the clamps 2 include a first clamp 21 and a second clamp 22 that are parallel to each other. The first clamp 21 and the second clamp 22 move toward and away from each other at the same speed at the same time; a pull rod 3 is provided on the side wall (i.e., the inner wall) that is relatively close to the first clamp 21 and the second clamp 22, and the other side is connected to the machine body 1 through a horizontally movable telescopic mechanism. The movement direction of the telescopic mechanism is the same as the movement direction of the clamp 2, and one end of the pull rod 3 is movably connected to the inner wall of the first clamp 21 and the second clamp 22, that is, the first clamp 21 and the second clamp 22 are respectively connected to each other. The inner wall of the plate 22 is connected with a movable tie rod 3, which can move along the length extension direction of the clamp plate 2 and rotate around the vertical axis. The other end is provided with a clamping mechanism, which is used to clamp the outer circle of the steel bar; the multiple tie rods 3 on the first clamp plate 21 and the multiple tie rods 3 on the second clamp plate 22 are staggered and arranged at intervals, that is, they are arranged in a staggered comb-like manner, and one end of the two adjacent tie rods 3 with the clamping mechanism is hinged through an equal-length connecting rod 4, that is, one end of the connecting rod 4 is hinged to the tie rod 3, and the other end is hinged to another adjacent tie rod 3; the cross-section of the welding bar device is an inverted V-shaped welding frame 9, and the top edge and two side edges of the V-shape are used to place long steel bars (three in total); the reinforcing bar platform is square, and the upper end of the periphery is equidistantly provided with limit grooves 10, which are used to clamp the outer circle of the steel bar. The material transfer between the reinforcing bar making equipment, the welding bar device, and the reinforcing bar platform is achieved by an electric hoist or a gantry truck.

[0034] Preferably, each of the pull rods 3 is provided with a slider 5, which can move along the extension direction of the clamping plate 2, and a V-shaped groove is provided on the side close to the locking mechanism. When the pull rod 3 shakes the steel bar, the force is applied through the V-shaped groove to force the steel bar to form a more standard V shape, thereby ensuring the consistency of the final product. If the V shape is not standard enough, a force can be applied to the slider 5 along the length extension direction of the clamping plate 2 at both ends of the clamping plate 2 (not shown in the figure), so that each slider 5 moves closer to the middle to ensure that a more standard V shape is formed.

[0035] Preferably, the slider 5 is provided with a latching tooth 51, and the body 1 is provided with a sliding groove 52 matching with the extending direction of the clamping plate 2. The latching tooth 51 cooperates with the sliding groove 52 to limit the slider 5 from reciprocating along the extending direction of the clamping plate 2.

[0036] Preferably, the clamping mechanism is two vertically arranged limit posts 6. The two limit posts 6 are cylindrical, the distance between them is slightly larger than the outer circle of the steel bar, the upper ends are open, and the opening can be set in a V-shaped opening, which is convenient for quickly placing the steel bar in the clamping mechanism and convenient for taking out and putting in.

[0037] Preferably, the side walls of the first clamping plate 21 and the second clamping plate 22 that are relatively close to each other are both provided with a guide groove 31 along the extension direction thereof, and the end of the pull rod 3 that is away from the engaging mechanism is provided with a roller 32 that cooperates with the guide groove 31. The cooperation between the roller 32 and the guide groove 31 limits the movement of one end of the pull rod 3 along the extension direction of the clamping plate 2. And the end of the pull rod 3 located in the middle of the second clamping plate 22 is fixedly connected to limit the overall deviation.

[0038] Preferably, the telescopic mechanism is an oil cylinder 7. The oil cylinder 7 enables the first clamping plate 21 and the second clamping plate 22 to move closer and farther at the same time.

[0039] Preferably, a guide assembly 8 in the same direction as the oil cylinder 7 is provided between the first clamping plate 21 , the second clamping plate 22 and the machine body 1 to guide the oil cylinder 7 .

[0040] Preferably, both sides of the welding frame 9 are provided with retaining edges 91. The retaining edges 91 are used to block the steel bars to prevent the steel bars on both sides of the welding frame 9 from falling.

[0041] Preferably, a U-shaped holder 92 is provided at the upper end of the welding frame 9. The U-shaped holder 92 is arranged at intervals and is used to limit the position of the steel bars placed on the top of the welding frame 9.

[0042] Preferably, the upper end of the limiting groove 10 is opened in a V-shape, which is convenient for workers to quickly lay each steel bar on the reinforcement platform and improve efficiency.

[0043] During specific use, the steel bars are placed in the locking mechanism through a lifting tool, and the telescopic mechanism drives the first clamping plate 21 and the second clamping plate 22 to move away at the same speed. Due to the limiting effect of the connecting rod 4, the steel bars are then pulled into a continuous and equal-sized V-shape. After being pulled into place, the continuous V-shaped frame is removed, the telescopic mechanism is reset, and the next drawing is carried out.

[0044] The two above-mentioned continuous V-shaped frames are installed in sequence by a lifting tool and placed on the two side walls of the welding frame 9 respectively. Then, three straight steel bars are lifted by the lifting tool and placed on the top and both sides of the welding frame 9 respectively, and close to the continuous V-shaped frame. Workers hold welding guns to weld each vertex of the continuous V-shaped frame, and finally form an isosceles trapezoidal reinforcement cage for strengthening the tensile strength of the prefabricated bottom plate.

[0045] A long straight steel bar is placed in each limit groove 10 of the reinforcement platform by using lifting tools to form the bottom layer. The second layer is then placed perpendicular to the lower layer with steel bars, and a reinforcement cage made as described above is placed at a certain distance. Next, workers manually tighten each cross node formed between the second layer and the lower layer with steel wire. At this point, the prefabricated bottom plate of the large-span composite slab is completed with the reinforcement plate, and finally only mold installation and slurry pouring are required.
