[0002] In the processing of the cap beam of the lower structure of a large bridge project, according to the requirements of the design drawings, a cap beam is composed of multiple cap beam frame pieces. Since the cap beam is too large (the dimensions of length, width and height are 15.1m×2.2m×1.8m), it is difficult to bind it on the plane and errors are prone to occur. In this construction method, the distance between the cap beam frame pieces is inconsistent, which affects the overall construction quality of the cap beam. Summary of the invention

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A steel frame for integrally assembling and binding a cap beam comprises a bottom frame, on which a plurality of groups of inner facade support columns are fixed along the left and right sides of the bottom frame in the length direction, the outer facade support columns and the inner facade support columns are arranged side by side and spaced apart and connected by longitudinal braces and transverse braces, on which a passage platform is laid; a transverse positioning device, a supporting device and a vertical positioning device are provided on the passage platform, wherein the transverse positioning device positions one side of a cap beam skeleton piece in the width direction, the supporting device hangs the cap beam skeleton piece, and the vertical positioning device positions one side of the cap beam skeleton piece in the length direction.

[0006] The transverse positioning devices are arranged in multiple groups at intervals, and each transverse positioning device includes a mounting seat, on which an adjusting bolt is threadedly connected. The adjusting bolt is in contact with a positioning plate, and the positioning plate is tightened against the width end of the cap beam frame piece.

[0007] The vertical positioning device is arranged in multiple groups. The vertical positioning device includes a pin hole fixed on the facade support column. One end of the positioning rod is inserted into the pin hole, and the other end positions the length end of the cap beam frame piece.

[0008] The utility model provides a steel frame for integrally assembling and tying a cap beam, which has the following technical effects:

[0009] 1) By using various sizes of steel and steel plates to weld to form a frame, multiple sets of cap beam skeleton pieces can be hung on the device in a three-dimensional manner using a supporting device; through the use of a horizontal positioning device, a vertical positioning device, and a positioning comb plate, the overall forming size of the cap beam and the spacing between the skeleton pieces can be accurately adjusted, thereby improving construction efficiency and ensuring construction quality.

[0010] 2) Through the lateral positioning device, installation and removal are completed by rotating the adjustable bolts, which is easy to operate and enables the steel frame for the overall assembly and binding of the cap beam to adapt to different cap beam sizes, helping to save labor and material costs.

[0011] 3) The vertical positioning device and the positioning comb plate can avoid the problem of uneven spacing between the cap beam frame pieces during the cap beam binding installation process, which helps to improve the installation accuracy and ensure the molding quality.

A plurality of vertically arranged inner facade support columns 2 are welded to the left and right sides of the bottom cross bars 6 along the length direction, and a plurality of outer facade support columns 1 are arranged side by side and at intervals outside the inner facade support columns 2. The outer facade support columns 1 and the inner facade support columns 2 on each side are connected by longitudinal braces 7 and transverse braces 8. The longitudinal braces 7 and transverse braces 8 are arranged in two layers, and a channel platform 11 is laid. The channel platform 11 is convenient for manual operations on both layers.

[0026] Here, the lower channel platforms 11 are arranged side by side, and the upper channel platform 11 is U-shaped.

[0027] like Figure 2 As shown, a lateral positioning device 13 is provided at one end of the upper channel platform 11, and the lateral positioning device 13 is arranged at the width end ( Fig.10 A vertical positioning device 15 is provided on one side of the channel platform 11. The vertical positioning device 15 is arranged on one side of the length direction of the cap beam skeleton piece ( Fig.10 b side) positioning.

[0028] like Figure 6-7 As shown, the lateral positioning device 13 is arranged in parallel in multiple pieces. Each lateral positioning device 13 includes a mounting seat 13.1, and the mounting seat 13.1 is welded from a steel plate into a rectangular notch, and the corresponding positioning plate 13.2 can be placed in the mounting seat 13.1 of the two lateral positioning devices 13 on the left and right outer sides. An adjusting bolt 13.3 is threadedly connected to the mounting seat 13.1, and the outer side of the adjusting bolt 13.3 is in contact with the positioning plate 13.2. During installation, the positioning plate 13.2 is placed at a determined position in the mounting seat 13.1, and then the adjusting bolt 13.3 is screwed in and tightened against the positioning plate 13.2. One end of all the cap beam skeleton pieces 4 hoisted in later is in contact with the positioning plate 13.2, so that one end of the cap beam skeleton piece 4 is positioned.

[0029] like Figure 2 , Fig. 9As shown, the vertical positioning device 15 includes a plurality of latch holes 15.1 arranged at intervals along the length direction, and each latch hole 15.1 is fixed to the corresponding facade support column 1. The latch holes 15.1 are welded from steel plates, and the positioning rods 15.2 are inserted into the corresponding latch holes 15.1 to prevent the cap beam frame sheet from deflecting.

[0030] In addition, a plurality of support devices 14 are placed on the channel platform 11. The support devices 14 are welded by two channel steels and one angle steel. Round steels are welded at both ends of the support devices 14 as pull rings 14.1.

[0034] like Fig.11 As shown, in addition, the device is equipped with a positioning comb plate 16 for positioning control.

[0035] Working principle and process: After the cap beam skeleton piece 4 is processed, the required cap beam skeleton piece 4 is hoisted into the interval between the left and right channel platforms 11 of this device by a bridge / gantry crane, and the length direction of the cap beam skeleton piece 4 is consistent with the length direction of this device. Multiple sets of support devices 14 are passed horizontally through the cap beam skeleton piece 4, and the support devices 14 are placed on the upper channel platform 11. In this way, when the subsequent crane is separated from the cap beam skeleton piece 4, the support device 14 can support the cap beam skeleton piece 4. In the process of lowering the cap beam skeleton piece 4 into place, the vertical positioning device 15 is used to position one side of the cap beam skeleton piece 4 (in the length direction), and the positioning comb plate 16 is used to further adjust the distance between the cap beam skeleton pieces 4; then the adjusting bolts 13.3 on the horizontal positioning device 13 are used to limit the end of the entire cap beam skeleton to determine the forming size of the cap beam. After being lowered into place, stirrups of different specifications are inserted in turn, and the installation position and spacing of the stirrups are controlled by the positioning comb plate 16. The operators then tie the stirrups on the first and second floor channel platforms and at the bottom of the cap beam. After the initial tying of the cap beam is completed, the supporting square steel pipes for lifting are inserted, the supporting device 14 is pulled out, and the whole is lifted out to the secondary tying platform using a bridge / gantry crane. The remaining horizontal bars around the cap beam skeleton piece 4 are tied. After completion, the finished product is stored in a fixed storage area.
