Technical Field

[0001] The utility model belongs to the technical field of engineering construction equipment, and particularly relates to an operation platform for positioning and installing U-shaped support bars. Background Art

[0002] There are a large number of U-shaped embedded bars on the bridge deck pavement. The deviation of their plane position and height directly affects the construction difficulty of the subsequent bridge deck concrete pavement and the control of the protective layer thickness. The traditional construction method is time-consuming and laborious, and the qualified rate of the construction plane position and height is low. Taking a 9.96m slab beam as an example, 40 U-shaped bars need to be embedded on the beam slab. When constructing by the traditional method, a worker needs to weld for more than 3 hours. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an operation platform for positioning and installing U-shaped support bars, which mainly solves the problem of low efficiency of manually laying U-shaped steel bars on the bridge deck.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The operation platform for positioning and installing U-shaped support bars includes a steel frame. The steel frame is a plate structure, rectangular. Rollers are installed corresponding to both sides at the bottom of the steel frame. Wheel rails are arranged at the bottom of both sides of the steel frame for the rollers to support and move.

[0006] A plurality of positioning frames are installed on the side of the steel frame. The side projection of the positioning frame is an L-shaped structure. The positioning frames are arranged along the length direction of the steel frame and are detachably installed and fixed on the steel frame.

[0007] Further, the steel frame is composed of upper and lower side support plates and square tubes. The upper and lower side support plates are parallel to each other, and both sides between the upper and lower side support plates are welded and fixed by square tubes.

[0008] Further, the lower side of the steel frame has a wheel frame corresponding to a single-side roller. The wheel frame is in a U shape. There are two rollers in the front and back of the single-side wheel frame. The corresponding wheel surface of the roller has a wheel groove. The wheel rail is an angle steel part, and the corresponding cross section of the wheel rail is L-shaped.

[0009] Further, the positioning frame has a hanging plate and a horizontal plate. The horizontal plate is used to support the arc part of the U-shaped bar. The hanging plate has a hanging buckle plate. A hanging groove is fixed on the side of the steel frame for the hanging buckle plate to be snapped into and detachably install the positioning frame.

[0010] The utility model has the following beneficial effects:

[0011] The U-shaped support rib positioning and installation operation platform is used to replace manual walking and positioning on the steel frame mesh, improving construction efficiency and quality. The platform is easy to manufacture, convenient to move, has good reliability, and can save labor. The construction efficiency is high. It is estimated that one beam and slab U-shaped rib can be constructed in one hour, with obvious cost reduction and efficiency improvement value. In addition, this platform can be slightly modified and applied to the construction sites of precast slabs and building floors, with a wide range of applications.

[0012] Through the activities of the project team, not only has the quality of the U-shaped ribs for bridge deck paving been significantly improved, but also the construction efficiency has been enhanced, achieving good economic benefits. Calculated based on the 60 beams that have been constructed so far, each beam saves 65 minutes, and a total of 60 beams save 65 / 60×90 = 65 hours of construction time. Calculated at 300 yuan per working day for a welder and 8 hours per working day, the economic benefits generated through improved efficiency are 65 / 8×300 = 2437.5 yuan.

[0015] Figure 2 : Schematic enlarged partial structural diagram of the present invention.

[0016] Figure 3 : Schematic working diagram corresponding to the upper side of the steel bars of the present invention.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] As Figures 1-3 shown: The U-shaped support rib positioning and installation operation platform includes a steel frame 1. The steel frame 1 is a plate structure, rectangular. Rollers 51 are installed corresponding to both sides at the bottom of the steel frame 1, and wheel rails 2 are provided at the bottom of both sides of the steel frame 1 for the rollers 51 to support and move;

[0020] A plurality of positioning frames 4 are installed on the side of the steel frame 1. The side projection of the positioning frame 4 is an L-shaped structure. The positioning frames 4 are arranged along the length direction of the steel frame 1 and are detachably installed and fixed on the steel frame 1.

[0021] The steel frame spans across the bridge deck in the length direction and is installed on the upper side of the embedded steel bars. The two sides of the wheel rails correspond to the structural frame for support. The wheel rails are used for the rollers to roll, and the length direction is perpendicular to the length direction of the steel frame, which is used for the steel frame to move longitudinally on the bridge deck to adjust the processing position.

[0022] The U-shaped bars are installed on the upper side of the bridge deck steel mesh. The U-shaped bars are supported at the corresponding circular positions by the positioning frame for support and positioning at the same time. The two side rod parts corresponding to the U-shaped bars are welded and fixed to the intersection points of the steel mesh. The upper side of the steel frame is for workers to walk on to switch the installation position of the U-shaped bars.

[0023] As Figure 2 shown: The steel frame 1 is composed of upper and lower side support plates 11 and square tubes 12. The upper and lower side support plates 11 are parallel to each other, and both sides between the upper and lower side support plates 11 are welded and fixed by square tubes 12 to improve the support performance of the steel frame. The lower side of the steel frame 1 corresponds to a single-sided roller 51 with a wheel frame 5. The wheel frame 5 is in a C shape, and there are two rollers 51 in the front and back of the single-sided wheel frame 5. The wheel shaft corresponding to the roller is installed on the wheel frame, and the wheel frame has a shaft hole for the wheel shaft to pass through.

[0024] The roller 51 has a wheel groove 52 on the corresponding wheel surface. The wheel rail 2 is an angle steel part, and the corresponding cross-section of the wheel rail 2 is L-shaped. Using the angle steel part as the wheel rail has low cost and convenient material selection, and the corresponding right-angle position exactly matches the wheel groove, making the roller walk stably. The positioning frame 4 has a suspension plate and a horizontal plate. The horizontal plate is used to support the arc part of the U-shaped bar 6. The suspension plate has a hanging buckle plate. A hanging groove 13 is fixed on the side of the steel frame 1 for the hanging buckle plate to be snapped into and detachably install the positioning frame 4. The hanging buckle plate is parallel to the suspension plate, and a groove body is formed between them for cooperation with the hanging groove, which is convenient for disassembly and position adjustment, and is used for precise adjustment of the steel mesh spacing and true determination of the welding points.

[0025] Use 10# channel steel as the support frame, A5 angle iron as the positioning frame, and set rollers at the lower part as the walking system. Lay A5 angle iron under the rollers as the walking track.

[0026] Fully cover the channel steel positioning frame with bamboo plywood, which is convenient for taking U-shaped bars and welding rods during construction and improves work efficiency. Considering the needs of rust prevention and aesthetics, paint is sprayed on the surface of the positioning frame.

[0027] This specification selects and specifically describes these embodiments to better explain the principle and practical application of the present invention, so that those skilled in the relevant technical field can well understand and utilize the present invention.
