Description

Technical Field

[0001] This application belongs to the field of precast wall panel production technology, and in particular relates to a support fixture for precast wall panel production. Background Technology

[0002] The production process of precast wall panels mainly includes preparing casting molds, erecting steel reinforcement frames, concrete pouring, curing, and demolding. The structure of the casting mold (6) is as follows: Figure 2 and Figure 3 As shown, the formwork includes two end templates 61 and two side templates 62. In application, the two end templates 61 and two side templates 62 form a rectangular frame structure and are installed on a bottom template. Both the end templates 61 and side templates 62 have multiple placement slots 63. The reinforcing bars include horizontal bars 64 and vertical bars 65. After the formwork is installed, the operator needs to place the ends of the multiple horizontal bars 64 sequentially into the corresponding placement slots 63 of the end templates 61, and the ends of the multiple vertical bars 65 sequentially into the corresponding placement slots 63 of the side templates 61. Figure 2 As shown, a mesh-like steel reinforcement skeleton is formed; then the operators will use wire to tie the intersection of the horizontal bars 64 and the vertical bars 65. The core purpose is to ensure that the mesh-like steel reinforcement skeleton maintains the precise design position and geometry during concrete pouring and vibration.

[0003] In actual operation, since most of the intersection points of the horizontal bars 64 and the vertical bars 65 are located in the middle of the mold, and the bottom mold is generally coated with a release agent and cannot be stepped on directly, and in order to ensure the geometric shape of the steel bars, the operators cannot step directly on the steel bars for binding. This makes the steel bar binding operation more cumbersome and less efficient, which is not conducive to improving the production efficiency of precast wall panels. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides a support fixture for the production of precast wall panels, which can effectively simplify the rebar tying operation and improve the production efficiency of precast wall panels.

[0005] To achieve the above objectives, the present invention employs the following technology:

[0006] A support fixture for precast wall panel production, used to support reinforcing bars installed in the wall panel casting mold, comprising:

[0007] Two strip panels are set parallel to each other and facing the same direction;

[0008] Two baffles are connected at both ends to two strip plates respectively; the two baffles are set perpendicular to the direction of the strip plates and are set at a predetermined distance apart;

[0009] Two mounting rods are positioned above the corresponding stop bars with the same orientation and are movable along the length of the stop bars; multiple mounting frames are arranged in an array along the length of each mounting rod on the opposite side of the two mounting rods, and the distance between two adjacent mounting frames matches the distribution of the reinforcing bars in the wall panel casting mold.

[0010] A fixing mechanism, located on the strip plate, is used to fix the baffle strip onto the casting mold;

[0011] The number of spacers is the same as that of the mounting brackets, and each spacer is placed on the mounting bracket. Each spacer is located below the stop bar and is used to vertically enter between the reinforcing bars and to support the reinforcing bars as the mounting rod moves.

[0012] Furthermore, the mounting bracket is configured with an L-shaped plate structure, with its horizontal part connected to the opposite side of the mounting rod along the length of the strip plate, and the vertical part of the mounting bracket extending below the stop bar; one side of the pad is connected to one side of the vertical part of the mounting bracket.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up the baffle, fixing mechanism, mounting rod, and mounting frame, and coordinating the movement of the mounting rod, the pad can be directly inserted between the horizontal reinforcement and the bottom formwork to support the horizontal reinforcement. This allows the operator to directly enter the casting mold to tie the mesh steel reinforcement skeleton, which greatly simplifies the tying operation and helps to improve the production efficiency of precast wall panels. At the same time, it can also maintain the geometric shape of the mesh steel reinforcement skeleton to improve the load-bearing capacity and rigidity of the produced precast wall panels.

[0015] 2. The L-shaped plate structure design of the mounting frame can leave the operating space required for operators to tie the intersection points, further simplifying the tying operation and improving tying efficiency. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0022] This application provides a support fixture for the production of precast wall panels, such as... Figures 1-4 As shown, it includes: two strip plates 1, two baffles 2, two mounting rods 3, a fixing mechanism 4, and a pad 5. In this embodiment, a mesh steel reinforcement skeleton composed of five horizontal bars 64 and five or more vertical bars 65 is used as an example for illustration.

[0023] like Figure 1 As shown, two strip plates 1 are arranged parallel to each other and facing the same direction, with one side of the two strip plates 1 facing each other; the distance between the two strip plates 1 is greater than the distance between the two side templates 62; the two ends of the two baffles 2 are respectively connected to one side of the two strip plates 1, and the orientation of the two baffles 2 is perpendicular to the orientation of the strip plates 1, with the baffles 2 located between the two sides of the strip plates 1; the distance between the two baffles 2 is greater than the distance between the two outermost vertical ribs 65 among the three adjacent vertical ribs 65.

[0024] like Figures 1-4 As shown, two mounting rods 3 are respectively positioned above the corresponding baffle 2 with the same orientation and are moved along the length of the baffle 2; five mounting brackets 31 are respectively arranged in an array along their length on the opposite side of the two mounting rods 3, and the distance between two adjacent mounting brackets 31 is equal to the distance between two adjacent horizontal ribs 64.

[0025] like Figures 1-4 As shown, a threaded hole 11 is provided in the middle of one of the strip plates 1 below the baffle 2 along the length of the baffle 2. The fixing mechanism 4 includes a screw 41 threaded into the threaded hole 11. The number of pads 5 is the same as the number of mounting brackets 31, and they are respectively set on the mounting brackets 31. Each pad 5 is located below the baffle 2, and the thickness of the pad 5 is equal to the distance between the bottom template and the horizontal rib 64.

[0026] During application, after the operator correctly installs the horizontal ribs 64 and vertical ribs 65, the horizontal ribs 64 are arranged along the length of the side template 62 and in an array along the length of the end template 61; the vertical ribs 65 are arranged along the length of the end template 61 and in an array along the length of the side template 62; the horizontal ribs 64 and vertical ribs 65 form a mesh-like skeleton structure.

[0027] like Figures 1-3 As shown, the installation rod 3 is first moved along the length of the stop bar 2 to adjust the position of the installation frame 31 and the pad 5, so that when the operator sets up the two stop bars 2 along the length of the end template 61 on the side template 62 on both sides of the three adjacent vertical bars 65, each pad 5 can pass through the grid formed by the three vertical bars 65 and the five horizontal bars 64 and abut against the bottom template.

[0028] like Figures 1-4 As shown, after the baffle 2 is erected, the two side templates 62 are located between the two strip plates 1. At this time, rotate the screw 41 so that one end of the screw 41 moves toward one of the side templates 62 until the screw 41 abuts against the outside of one of the side templates 62. At the same time, the other strip plate 1 abuts against the outside of the other side template 62 under the pressing action of the screw 41, thereby fixing the two baffles 2 on the casting mold.

[0029] After the stop bar 2 is fixed, the mounting rod 3 is moved to move each pad 5 directly below the corresponding horizontal reinforcement 64. At this time, the bottom surface of the pad 5 abuts against the bottom template, and the top surface supports the horizontal reinforcement 64. The operator can directly step on the horizontal reinforcement 64 with the pad 5 underneath to tie the intersection of the horizontal reinforcement 64 and the vertical reinforcement 65 in the middle of the casting mold. With the action of the pad 5, the operator can directly enter the casting mold to tie the mesh steel reinforcement skeleton, which greatly simplifies the tying operation and helps to improve the production efficiency of precast wall panels. At the same time, it can also maintain the geometric shape of the mesh steel reinforcement skeleton to improve the load-bearing capacity and rigidity of the produced precast wall panels.

[0030] After binding the intersection points corresponding to the three vertical ribs 65 and the horizontal ribs 64, the tooling can be removed, and the above operation can be repeated to continue binding the subsequent intersection points.

[0031] Specifically, Figures 1-4As shown, the mounting frame 31 is configured with an L-shaped plate structure. Its horizontal part is connected to the opposite side of the mounting rod 3 along the length of the strip plate 1. The vertical part of the mounting frame 31 extends below the stop strip 2, and one side of the pad 4 is connected to one side of the vertical part of the mounting frame 31. When the two stop strips 2 are fixedly erected on the side templates 62 on both sides of the three adjacent vertical ribs 65 along the length of the end template 61, the vertical part of each mounting frame 31 can pass through the grid formed by the three vertical ribs 65 and the five horizontal ribs 64 with the pad 5. The pad 5 abuts against the bottom template and enters between the horizontal ribs 64 and the bottom template as the mounting rod 5 moves. At this time, since the mounting frame 31 is configured with an L-shaped plate structure, the intersection points of the vertical ribs 65 and the horizontal ribs 64 on both sides of the three vertical ribs 65 are all located below the horizontal part of the corresponding mounting frame 31. The L-shaped plate structure design of the mounting frame 31 can leave the operating space required for the operator to tie the intersection points, further simplifying the tying operation and improving the tying efficiency.

[0032] Specifically, such as Figures 1-4 As shown, two guide rods 21 are provided above each of the two baffles 2 in the same direction. The two ends of the guide rods 21 are respectively connected to the two strip plates 1. Two mounting rods 3 are slidably passed through the corresponding guide rods 21. A rotating rod 32 is rotatably connected to the opposite side of one end of each of the two mounting rods 3. Its rotation axis is set along the width direction of the strip plate 1. A folding plate 33 is provided perpendicularly at the end of the rotating rod 32. A spring 22 is sleeved on each guide rod 21. The spring 22 is connected between one end of the mounting rod 3 and the opposite strip plate 1. When the spring 22 is compressed to a predetermined length, the folding plate 33 is used to fasten the outside of the strip plate 1. Before using the tooling, the mounting rod 3 can be moved to compress the spring 22 to a predetermined length. Then, the rotating rod 32 is turned to the corresponding strip plate 1, so that the folding plate 33 at the end of the rotating rod 32 latches onto the outside of the strip plate 1 to fix the mounting rod 3. At this time, the position of the mounting rod 3 allows each pad 5 to pass through the grid formed by the three vertical ribs 65 and the five horizontal ribs 64 when the stop strip 2 is erected. Through the setting of the spring 22, the rotating rod 32, and the folding plate 33, the operator can quickly adjust and position the mounting rod 3 to the installation position, further improving the production efficiency of the precast wall panel. After the stop strip 2 is fixed, the folding plate 33 is moved away from the outside of the strip plate 1, the spring 22 extends, and the pad 5 can be pushed between the corresponding horizontal rib 64 and the bottom template, thereby realizing the rapid installation of the pad 5 and further improving the binding efficiency.

[0033] Preferred, such as Figure 4 As shown, a pulley 51 is rotatably provided at the bottom of the pad 5, with its rotation axis arranged along the length of the strip plate 1. When the pulley 51 abuts against the bottom template, the pad 5 can move under the horizontal rib 64 for support. Under the action of the pulley 51, the friction between the pad 5 and the bottom template can be reduced, ensuring that the pad 5 can stably move under the horizontal rib 64, thereby improving the reliability of the tooling.

[0034] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
