Description

Technical Field

[0001] The utility model relates to the technical field of tunnel steel arch frame installation, and more specifically, to a simple adjustment device for a tunnel steel arch frame connecting plate. Background Art

[0002] During the assembly of the tunnel steel arch frame, the deformation often causes the connection plate of the next section of the steel arch frame to not fit closely with the connection plate of the previous section of the steel arch frame, and even to be staggered or open, which seriously affects the quality of the on-site steel arch frame assembly. In this case, the individual bolt holes on the steel arch frame connection plate are generally aligned first, and the bolts are inserted, and then the steel frame is twisted to align the other bolt holes to insert the bolts. However, this method cannot completely guarantee its alignment and close fit, and the quality of the steel arch frame connection is poor. In order to ensure the quality of the steel arch frame connection and the stiffness of the joint, a simple adjustment device for the tunnel steel arch frame connection plate is needed to adjust the steel arch frame connection plate.

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0016] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0017] like Figures 1 to 3 As shown, the utility model provides a simple adjustment device for a tunnel steel arch frame connecting plate, comprising: an adjustment bracket, which includes two S-shaped bracket steel pipes 5, the middle parts of the two bracket steel pipes 5 are hinged to form a scissor-type structure; the ends of the two bracket steel pipes 5 on the same side are fixedly connected with clamps 3, and grooves are provided on the opposite sides of the two clamps 3, and the grooves extend from one end where the clamps 3 are connected to the bracket steel pipe 5 to the other end, and an opening is formed at the other end; the grooves of the two clamps 3 jointly clamp the two sides of the steel arch frame connecting plate 2.

[0018] In this technical solution, the tunnel steel arch assembly process requires that the steel arch connecting plates 2 at one end of the two steel arches 1 be aligned and pressed together. One end of the clamp 3 is fixedly connected to the support steel pipe 5, and the other opposite end is set as an opening, which is connected to the groove so that one side of the steel arch connecting plate 2 can be clamped through the groove, and the other end of the groove opposite to the opening can be abutted against the end of the steel arch connecting plate 2. The two sides of the steel arch connecting plate 2 are clamped together by the grooves of the two clamps 3, so that the two steel arch connecting plates 2 are aligned and pressed together, and then the position of the two steel arch connecting plates 2 is adjusted at the same time by holding the end of the adjustment bracket away from the steel arch connecting plate 2.

[0019] In another technical solution, the support steel pipe 5 includes a clamping portion 51, a connecting portion 52 and an operating portion 53 which are fixedly connected in sequence to form an S-shaped shape. The clamping portion 51 and the operating portion 53 are steel pipes, the connecting portion 52 is a steel plate, and a hinge hole is provided at the center of the connecting portion 52. One end of the clamping portion 51 away from the connecting portion 52 is fixedly connected to the clamping hand 3, and the operating portion 53 is used for hand-held operation by a staff. In actual use, the clamping portion 51, the connecting portion 52 and the operating portion 53 are fully welded in sequence, and the clamping portion 51 and the clamping hand 3 are also fully welded.

[0020] Furthermore, the hinge holes on the two support steel pipes 5 are connected by a pin 4 to form a scissor-type structure. At this time, the two clamping parts 51 are parallel to each other. The staff can control the two clamping hands 3 to clamp the steel arch connecting plate 2 by controlling the two operating parts 53. Preferably, the diameter of the pin 4 is smaller than the diameter of the hinge hole, so that the two support steel pipes 5 can be adjusted up and down in a small range.

[0021] In another technical solution, the height of the groove is greater than the sum of the thicknesses of the two steel arch connecting plates 2. Preferably, the height of the groove is slightly greater than the thickness of the two steel arch connecting plates 2. When in use, the openings of the two clamps 3 are aligned with the two sides of the steel arch connecting plates 2, and the two clamps are pushed forward in the longitudinal direction of the steel arch connecting plates 2, so that the grooves of the two clamps 2 are clamped on the two sides of the steel arch connecting plates 2, and then the adjustment bracket is manually controlled to adjust left and right and up and down, and the steel arch connecting plates 2 are squeezed through the four inner walls of the clamps, so that the two steel arch connecting plates 2 are aligned and close.

[0022] In another technical solution, a plurality of vertically penetrating through grooves are spaced apart on two opposite side walls of the groove, and the number and spacing of the through grooves are adjusted according to the site conditions to minimize the deadweight of the entire structure.

[0023] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
