Description

Technical Field

[0001] This utility model relates to the field of prefabricated component technology, and in particular to a jig suitable for prefabricating bridge deck steel cages. Background Technology

[0002] Currently, in the precast concrete bridge deck component manufacturing process at the beam yard, the traditional rebar tying process requires workers to tie the rebar cages onto molds. Due to the high requirements for the horizontal and vertical spacing of the rebars, this process occupies bridge deck molds and takes a long time, significantly affecting the turnaround speed of bridge deck molds and reducing the efficiency of precast bridge deck production. For large precast components, molds for precast components are purchased according to the rebar cages. The molds themselves are costly, and an excessive number of molds will increase production costs. Utility Model Content

[0003] The purpose of this utility model is to provide a jig suitable for prefabricated bridge deck steel cage production, so as to solve the problems encountered in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A jig suitable for prefabricating bridge deck steel cages includes an upper frame, a lower frame, and a support frame. The top of the support frame is fixedly connected to the lower frame, and the top of the support frame also contacts the upper frame via a bracket. The lower frame has inclined sides on both sides, and positioning grooves are provided at equal intervals on the top of the upper frame, the top of the lower frame, and the top of the inclined sides.

[0006] In the above scheme, the upper frame includes several first vertical plates and several first horizontal plates, which are arranged perpendicularly to each other, and the positioning groove is located on the top of the first vertical plates and the first horizontal plates.

[0007] In the above scheme, the lower frame includes several second horizontal plates and several second vertical plates, which are arranged perpendicularly to each other. The inclined sides are arranged on both sides of each second vertical plate, and the positioning grooves are arranged on the top of the second vertical plates and the second horizontal plates.

[0008] As a preferred embodiment, the two ends of the lower frame are fixed with first suspended edges, and the top of the first suspended edges is also provided with positioning grooves at equal intervals. The first suspended edge includes a square steel pipe and a side edge. The bottom of the square steel pipe is fixedly connected to the two ends of the lower frame, and the top of the square steel pipe is fixedly connected to the side edge. The positioning groove is located on the top of the side edge.

[0009] As an additional technical solution, in one embodiment, a second overhead side is placed on top of the first overhead side, and the second overhead side is held in the middle by two front and rear second longitudinal plates. Furthermore, for ease of manufacturing, the structure of the second overhead side is the same as that of the first overhead side, with a vertical orientation, and whether or not to include a second overhead side can be determined as needed.

[0010] In the above scheme, the support frame includes support legs, which are evenly fixed to the bottom of the lower frame, and the bottom of the inclined side is provided with a reinforcing tube to fix two adjacent support legs. In addition, the bracket includes a square tube column and an I-beam block. The square tube column is vertically fixed to the top of the lower frame, the top of the square tube column is fixedly connected to the I-beam block, and the top of the I-beam block is engaged with the plate of the upper frame.

[0011] Compared with existing technologies, the advantages of this invention are as follows: First, reinforcing bars are placed in the positioning groove, and then the intersections of the reinforcing bars in the horizontal and vertical directions are tied according to their positions. Furthermore, the reinforcing bars can be tied along the diagonal sides to form a reinforcing cage with a sloping surface. After the reinforcing bars on the lower frame are tied, the reinforcing bars on the upper frame are tied separately, and finally, they are assembled to form a complete reinforcing cage. Placing the reinforcing cage into a mold forms the jig for the bridge deck component mold, and the precast bridge deck component can be obtained by pouring concrete. Because the reinforcing cage is tied directly on-site, there is no need to customize molds of different specifications, which greatly saves on mold ordering costs and shortens the production cycle of the precast bridge deck component.

These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0024] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0025] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1, such as Figures 1 to 7 As shown, a jig suitable for prefabricating bridge deck reinforcement cages includes an upper frame 1, a lower frame 2, and a support frame 3. The top of the support frame 3 is fixedly connected to the lower frame 2, raising the lower frame 2 to facilitate workers binding the reinforcement cage on it. The top of the support frame 3 also contacts the upper frame 1 via a bracket 31, meaning the upper frame 1, lower frame 2, and support frame 3 are movably connected and separable. The lower frame 2 has inclined sides 25 on both sides for prefabricating reinforcement cages with inclined sides. Positioning grooves 13 are provided at equal intervals on the top of the upper frame 1, the top of the lower frame 2, and the top of the inclined sides 25. These positioning grooves 13 are used to install reinforcement bars for workers to bind them.

[0027] In this scheme, reinforcing bars are first placed on the positioning groove 13, and then the intersections of the reinforcing bars in the horizontal and vertical directions are tied according to their positions. The reinforcing bars can be tied along the inclined side 25 to form a reinforcing cage with a slope. After the reinforcing bars on the lower frame 2 are tied, the reinforcing bars on the upper frame 1 are tied separately, and finally, they are assembled to form a complete reinforcing cage. Placing the reinforcing cage into the mold forms the jig for the bridge deck component mold, and the precast bridge deck component is obtained by pouring concrete. Because the reinforcing cage is tied directly on site, there is no need to customize molds of different specifications, which greatly saves the ordering cost of molds and shortens the production cycle of the precast bridge deck component.

[0028] Example 2, based on the solution of Example 1, please refer to... Figure 5 The upper frame 1 includes several first longitudinal plates 11 and several first transverse plates 12, which are arranged perpendicularly to each other. The positioning grooves 13 are semi-circular slots and are formed at the top of the first longitudinal plates 11 and the first transverse plates 12. After the reinforcing bars are placed according to the positioning grooves 13 at the top of the first longitudinal plates 11 and the first transverse plates 12, the workers then tie them together with steel wire.

[0029] Please see Figure 8 The lower frame 2 includes several second horizontal plates 21 and several second vertical plates 22, which are arranged perpendicularly to each other. Inclined edges 25 are provided on both sides of each second vertical plate 22, and positioning grooves 13 are provided on the top of the second vertical plates 22 and the second horizontal plates 21. Similar to the implementation of the upper frame 1, after the reinforcing bars are placed according to the positioning grooves 13 on the top of the second horizontal plates 21 and the second vertical plates 22, workers then bind them with steel wire. The reinforcing bars placed at the inclined edges 25 are also placed at an angle to form the inclined surface of the reinforcing cage.

[0030] Please see Figure 8 and Figure 9 The support frame 3 includes support legs, which are evenly fixed to the bottom of the lower frame 2. The bottom of the inclined side 25 is provided with a reinforcing tube 32 for welding and fixing two adjacent support legs, which is used to stabilize the inclined surface of the frame.

[0031] Because the top of the support frame 3 is in contact with the upper frame 1 through the bracket 31, the bracket 31 specifically includes a square tube column and an I-beam block. The square tube column is vertically fixed to the top of the lower frame 2, and the top of the square tube column is fixedly connected to the I-beam block. The top of the I-beam block is engaged with the plate of the upper frame 1. The top of the I-beam block has a U-shaped structure, specifically, it is engaged with the first longitudinal plate 11 at equal distances.

[0032] The reason for designing the upper frame 1 and lower frame 2, which can be disassembled, is that the rebar cage is also divided into upper and lower parts. Only by operating the two parts separately can it be easy to tie them together. Furthermore, since the model of the rebar cage is determined by the position of the positioning slots 13, several positioning slots 13 are set at equal intervals on the upper frame 1 and lower frame 2, which can be used to tie rebar cages of different specifications. In normal operation, to prevent the upper frame 1 from occupying space, it is placed on the lower frame 2 by snapping it together, thus saving production space.

[0033] In Example 3, based on Example 2, a first suspended edge 23 is fixed to both ends of the lower frame 2, and positioning grooves 13 are also provided at equal intervals on the top of the first suspended edge 23. Specifically, the first suspended edge 23 includes a square steel pipe and a side. The bottom of the square steel pipe is welded and fixedly connected to both ends of the lower frame 2, and the top of the square steel pipe is welded and fixedly connected to the side. The positioning grooves 13 are located on the top of the side. By separately setting the first suspended edge 23 to suspend both ends of the lower frame 2, steel cages with different slopes are made according to the slope of the steel cage, and then placed in a mold to form the jig for the precast bridge deck component.

[0034] As a preferred embodiment, a second hollow edge 24 is placed on top of the first hollow edge 23. The second hollow edge 24 is held in the middle by two second longitudinal plates 22 at the front and rear, and the two are detachably connected. Furthermore, for ease of manufacturing, the structure of the second hollow edge 24 is the same as that of the first hollow edge 23, and it has a vertical orientation. Whether or not to include the second hollow edge 24 can be determined as needed.

[0035] By setting the second overhead side 24, it is also possible to tie out steel cages with smaller slope angles at both ends of the overhead frame 2, which is suitable for different precast component mold needs.
