Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge decoration, in particular to an inverted triangular truss hanging basket for bridge appearance decoration. Background Technique
[0002] The pier mainly consists of a top cap and a pier body. The abutment mainly consists of a top cap and a abutment body. The function of the top cap is to disperse and evenly transmit the large and concentrated force transmitted by the bridge span support to the pier body and the abutment body. Therefore, the top cap should be built with materials of higher strength, generally built with reinforced concrete not less than grade 200, and the thickness is not less than 40 cm. In addition, the top cap must also have a relatively large plane size to provide a necessary working surface for beam erection during construction and maintenance. The pier body and the abutment body are the main structures supporting the bridge span. They not only bear all the loads transmitted by the bridge span structure, but also directly bear various loads such as earth pressure, water flow impact force, ice pressure, ship impact force, etc. Therefore, the pier body and the abutment body both have sufficient strength, stiffness and stability.
[0003] Currently, when decorating a relatively wide pier, the truss hanging basket required has a large span. Due to the load-bearing, the longitudinal main beam is prone to deformation, and at the same time, the two ends are prone to shaking, which has a great impact on the safety of construction. Content of the Utility Model
[0004] The utility model aims to solve the problems of the prior art and provides an inverted triangular truss hanging basket for bridge appearance decoration.
[0005] To solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

A plurality of second inclined rods are welded at equal intervals on the front and rear sides of the frame body. A triangular truss is welded at the bottom of the frame body, and the tip of the triangular truss faces downward. The frame body and the triangular truss are both welded by hollow steel pipes. Rectangular steel pipes are welded near the front and rear sides of the top of the frame body. An anti-slip plate is laid on the inner bottom surface of the frame body.
[0007] Optionally, openings are provided at the tops of the two rectangular steel pipes, side openings are provided on the front and rear sides of the two rectangular steel pipes, and a plurality of guides are arranged inside the two rectangular steel pipes.
[0008] Optionally, the guide includes a slider, and guide rods are fixed on both sides of the slider. One ends of the two guide rods respectively extend into the side openings correspondingly.
[0009] Optionally, locking nuts are threadedly connected to the outer surfaces of both of the guide rods, and one sides of both of the locking nuts are respectively in contact with the outer surface of the rectangular steel pipe.
[0010] Optionally, a cavity is formed inside the slider, a buffer seat is arranged inside the cavity, and the top of the buffer seat slidably extends above the slider.
[0011] Optionally, a roller is rotatably connected to the top of the buffer seat, and a spring is fixed between the inner bottom surface of the cavity and the bottom of the buffer seat.
[0012] Optionally, limiting grooves are formed in both inner side walls of the cavity, and limiting plates which are slidably engaged inside the limiting grooves are fixed to both sides of the buffer seat.
[0013] Optionally, two suspension ropes are arranged at the top of the frame body, and supports are arranged at both sides of the bottom of the frame body close to the edges.
[0014] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below:
[0015] 1. In the utility model, a triangular truss is welded to the bottom of the frame body, and the bottom of the triangular truss faces downward, so that the bending resistance strength of the frame body can be enhanced, and the situation that the longitudinal main beam is prone to deformation due to load bearing during large-span distances can be avoided. At the same time, both the frame body and the triangular truss are welded by hollow steel pipes, which can reduce the overall weight.
[0016] 2. In the utility model, a rectangular steel pipe is welded to the top of the frame body, and the top of the rectangular steel pipe is provided with an opening for facilitating the installation of a guide. When the frame body is moved after the top of the frame body comes into contact with the bottom of the pier, since the bottom of the pier is uneven, it is easy to scratch the bottom of the pier during the movement. At this time, the roller on the guide can prevent the top of the frame body from coming into contact with the bottom of the pier, and at the same time, when passing through the uneven part at the bottom of the pier, the spring can buffer to avoid rigid impact at the contact part and damage the contact part.
