Description

Technical Field

[0001] This utility model relates to an auxiliary frame, and more particularly to a novel auxiliary device for ground assembly of steel space frames, belonging to the field of steel space frame installation technology. Background Technology

[0002] Steel space frames, as a common form of spatial structure, are widely used in modern construction engineering due to their advantages such as lightweight structure, reasonable stress distribution, and convenient construction. Among these methods, the high-altitude assembly method is a common construction technique for steel space frame installation. This method involves hoisting the initial space frame in sections to form stable structural units, followed by assembling smaller triangular units on the ground and installing them using the high-altitude assembly method. Each small unit typically consists of a sphere and three to four members. Despite the widespread use of the high-altitude assembly method in engineering, the ground assembly phase of steel space frames still presents numerous challenges in actual construction. Traditional assembly methods, such as using cranes or manually assembling members, are prone to damage during hoisting due to improper operation or equipment malfunction. These methods are not only complex but also time-consuming, severely impacting the overall installation progress of the steel space frame. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a new type of auxiliary device for ground assembly of steel grid frame, which avoids damage to the members due to improper operation or equipment failure when using lifting devices for assembly, thereby improving work efficiency and reducing construction difficulty.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A novel auxiliary device for ground assembly of steel space frame includes a round steel U-shaped fork and a round steel support rod. The round steel U-shaped fork has a round steel support rod at its bottom. Rubber sleeves are respectively provided on the outside of the round steel U-shaped fork and the round steel support rod. A displacement sleeve is fitted on the round steel support rod. Positioning plates are respectively provided on both sides of the displacement sleeve. A disc is provided at the right end of the positioning plate, and a guide cylinder is rotatably connected between the two discs. A support column is provided inside the guide cylinder. A limit frame is provided at the right end of the support column. The guide cylinder is fixedly connected to the disc by bolts.

[0006] The support column is fixedly connected to the guide cylinder by bolts.

[0007] Bolt holes are evenly distributed around the perimeter of the disc, and matching nuts are installed in the bolt holes to fix the guide cylinder to the disc.

[0008] The displacement sleeve is fixedly connected to the round steel support rod by bolts.

[0009] The bottom of the round steel support rod is provided with a footrest, which is distributed in a U-shape, and the inner end of the footrest is rotatably connected to the outer wall of the bottom of the round steel support rod.

[0010] The rubber sleeve is made of polyethylene tubing.

[0011] The limiting frame is distributed in a V-shape.

[0012] The positive and beneficial effects of this utility model are:

[0013] 1. This utility model, by setting a round steel U-shaped fork at the top of the round steel support rod, can assist workers in quickly assembling the steel space frame without using lifting equipment, reducing the burden on workers, and is convenient and easy to use.

[0014] 2. This utility model provides rubber sleeves on the round steel U-shaped fork and the round steel support rod to prevent wear on the paint on the surface of the rod. At the same time, holding the rubber sleeve on the outside of the round steel support rod increases friction, ensuring the stability of the rod and preventing damage caused by misoperation.

[0015] 3. This utility model has a guide cylinder rotatably connected between two discs, and a support column and a limiting frame are set inside the guide cylinder. The tilt angle of the limiting frame can be adjusted according to the construction situation, so as to better support the rod and ensure the stability of the rod during the assembly process.

[0016] 4. This utility model features a footrest that is rotatably connected to the bottom of the round steel support rod. When in use, the worker steps on the footrest, which enhances the stability of the device on the ground and ensures a smoother assembly process. Attached Figure Description

[0021] The present invention will be further explained and described below with reference to the accompanying drawings:

[0022] See the example. Figures 1-3 A novel auxiliary device for ground assembly of steel space frame includes a round steel U-shaped fork 1 and a round steel support rod 3. The round steel support rod 3 is set at the bottom of the round steel U-shaped fork 1. Rubber sleeves 2 are respectively set on the outside of the round steel U-shaped fork 1 and the round steel support rod 3. Specifically, the lower middle part of the round steel U-shaped fork is set with a matching rubber sleeve, and the middle part of the round steel support rod is set with a rubber sleeve. A displacement sleeve 4 is fitted on the round steel support rod 3. Positioning plates 5 are respectively set on both sides of the displacement sleeve 4. A disc 6 is set at the right end of the positioning plate 5. A guide cylinder 7 is rotatably connected between the two discs 6. A support column 8 is set inside the guide cylinder 7. A limit frame 9 is set at the right end of the support column 8. The guide cylinder 7 is fixedly connected to the disc 6 by bolts.

[0023] The support column 8 is fixedly connected to the guide cylinder 7 by bolts.

[0024] Bolt holes 601 are evenly arranged around the perimeter of the disc 6, and matching nuts are installed in the bolt holes 601 to fix the guide cylinder 7 to the disc 6.

[0025] The displacement sleeve 4 is fixedly connected to the round steel support rod 3 by bolts.

[0026] The bottom of the round steel support rod 3 is provided with a footrest 10, which is distributed in a U-shape. The inner end of the footrest 10 is rotatably connected to the outer wall of the bottom of the round steel support rod 3.

[0027] Rubber sleeve 2 is made of polyethylene tubing.

[0028] The limit frame 9 is distributed in a V-shape.

[0029] In the above description, the support rod 8 is telescopic. When in use, the telescopic degree of the support rod is adjusted according to the distance between the round steel support rod and the rod, and the support rod is fixed by bolts on the outer wall of the guide cylinder.

[0030] In the above description, bolt holes are evenly arranged on the outer edge of the disc. When the angle of the guide cylinder changes, bolts are installed in the corresponding bolt holes to fix the guide cylinder and the disc together.

[0031] In the above description, the outer wall of the guide cylinder is provided with a positioning groove corresponding to the bolt hole position for fixing the bolt.

[0032] When using this device, two people work together to assemble the small unit rods. One person holds the device vertically while the other person places the middle part of the rod on the U-shaped steel fork of the device. At the same time, the position of the limiting frame is adjusted to tighten the middle part of the rod. Meanwhile, after the worker steps on the foot pedal, the end of the rod is aligned with the bolt ball and screwed into the bolt hole. Then, the bolt is tightened with a wrench to fix it. This device mainly serves to support the rods. Using this device instead of a lifting device reduces construction costs, is flexible, convenient, and quick to move, effectively reduces the assembly time of small unit rods, and avoids damage to the rods caused by misoperation when using lifting machinery.

[0033] This invention, by setting a round steel U-shaped fork at the top of the round steel support rod, can assist workers in quickly assembling the steel space frame without using lifting equipment, reducing the burden on workers, lowering the construction difficulty, and making it convenient and easy to use.
