Description

Technical Field

[0001] This utility model belongs to the field of construction sites, and specifically relates to a movable support for H-shaped steel guidance and positioning. Background Technology

[0002] During SMW (Sequencing Mixing Method) pile construction, H-beams are inserted primarily by their own weight using cranes. However, in strata containing gravel and pebbles, the hardness of the gravel and pebbles prevents the mixing piles from completely breaking them down. This causes resistance during H-beam insertion, leading to insufficient insertion depth or vertical displacement. While some insertion positioning devices exist, most only provide initial positioning and cannot continuously guide and position the H-beam during insertion, resulting in insufficient verticality. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a movable bracket for H-beam steel guiding and positioning.

[0004] This invention is achieved through the following technical solution:

[0005] A movable support for guiding and positioning H-beams includes guide rails fixed on both sides of a trench. Four rollers are symmetrically arranged inside the guide rails on both sides. The rollers have a braking function. The rollers are connected to the support upwards. The support includes several layers of grid frames. The upper and lower grid frames are fixedly connected together by vertical rods. The grid frames include two lateral limiting rods and two longitudinal limiting rods. The space enclosed by the two lateral limiting rods and the two longitudinal limiting rods matches the dimensions of the H-beams. The lateral limiting rods are perpendicular to the guide rails. The lowest lateral positioning rod is connected to the rollers downwards.

[0006] Preferably, the grid frame has three layers, with a spacing of 1-2m between each layer.

[0007] Preferably, the guide rail is made of channel steel.

[0008] Preferably, the roller is an electric roller.

[0009] Preferably, the guide rail is 20m long.

[0010] The movable bracket for guiding and positioning H-beams of the present invention can continuously guide and position H-beams, effectively improving the verticality of H-beam insertion; the bracket can move quickly along the guide rail, making it convenient to move the bracket position, improving construction efficiency, and avoiding the problem of difficult insertion due to hardening of cement slurry caused by slow construction.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0017] This embodiment includes guide rails 1 fixed on both sides of the trench. The guide rails 1 can be simple guide rails made of channel steel commonly used on construction sites, or they can be heavy-duty professional guide rails commonly used in industry. The guide rails 1 are symmetrically fixed on both sides of the trench. In this embodiment, the total length of the guide rails 1 is 20m, and the length can be selected according to the actual situation. Two rollers 2 are provided in each side of the guide rail 1. The rollers 2 are symmetrically arranged in both sides of the guide rail 1, resulting in a total of four rollers 2 symmetrically arranged in both sides of the guide rail 1. The rollers 2 can slide along the guide rail 1, and they also have a braking function, stopping on the guide rail 1. Preferably, the rollers 2 are electric wheels, with electric control of the rolling and stopping of the rollers 2.

[0018] Roller 2 connects upward to the bracket, and roller 2 drives the bracket to move along guide rail 1. The bracket includes several layers of grid frame 3, and the upper and lower grid frames 3 are fixedly connected together by vertical rods 4. In this embodiment, the grid frame 3 has three layers, with a spacing of 1.5m between each layer, and the total height of the bracket is approximately 3m. The number of layers of grid frame 3 can be selected as needed, or the grid frame 3 can be set to two layers. The grid frame 3 includes two transverse limiting rods 5 and two longitudinal limiting rods 6, which form a grid shape. Among them, the transverse limiting rods 5 are perpendicular to the guide rail 1, and the lowest transverse positioning rod is connected downward to roller 2. Each of the lowest transverse positioning rods is connected to a roller 2 in the guide rail 1 on both sides. The space enclosed by the two transverse limiting rods 5 and the two longitudinal limiting rods 6 matches the size of the H-beam. The H-beam can be inserted into the internal space enclosed by the two transverse limiting rods 5 and the two longitudinal limiting rods 6, thereby guiding and limiting the H-beam.

[0019] During construction, guide rails 1 are fixed on both sides of the trench. Rollers 2 and brackets are placed on guide rails 1. The brackets are moved to the position where the H-beam needs to be inserted. The brake rollers 2 are stopped. A crane is used to lift the H-beam and slowly place it layer by layer into the space enclosed by the horizontal limiting rods 5 and the vertical limiting rods 6 of the bracket. The space enclosed by the horizontal limiting rods 5 and the vertical limiting rods 6 of each layer will limit the H-beam, so that the H-beam always remains vertical. During the downward insertion of the H-beam, the device of this invention can continuously position and guide the H-beam, which effectively improves the verticality of the H-beam insertion compared to existing devices that only position the H-beam.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
