Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure workshop or high-rise steel structure installation, and specifically relates to a positioning device for steel beam installation. Background Art

[0002] In the installation of steel structure workshops or high-rise steel structures, beam-column connections and primary and secondary beam connections are mainly connected by high-strength bolts or high-strength bolts + welding. Since the bolt holes and high-strength bolts are matched with a slight gap, a slight deviation during high-altitude operations will make it difficult to penetrate the bolts, resulting in failure of beam-column connections and primary and secondary beam connections. Therefore, ensuring that the steel beams are quickly and accurately positioned and smoothly penetrated by high-strength bolts during steel beam installation is the key to steel structure construction.

[0003] At present, the method of installing steel beams is to use lifting equipment to lift the steel beams to the installation height, and then the installers use steel crowbars to forcibly pry the steel beams to be installed to the same joint surface height of the column connecting plate. At this time, the bolt holes of the web of the steel beam and the bolt holes of the column connecting plate are basically aligned, and the steel beam is basically positioned. At this time, another installer is required to insert high-strength bolts into the bolt holes for installation. This traditional installation method is difficult to center the bolt holes, has high operation intensity, is risky for high-altitude installation, requires multiple people to cooperate, and has low work efficiency. Summary of the invention

[0004] The utility model aims to solve the deficiencies of the prior art and provide a steel beam installation and positioning device that can accurately and quickly position the steel beam during the steel beam installation process, so as to solve the problems of difficulty in bolt penetration and low installation efficiency.

[0005] To achieve the above purpose, the solution adopted by the utility model is as follows:

[0006] A positioning device for steel beam installation, comprising a group of first bolt holes respectively opened at both ends of the steel beam web, a connecting rib plate respectively fixed to the inner sides of two steel beam connecting columns, a group of second bolt holes opened on the connecting rib plate, an eye punch, high-strength bolts and nuts;

[0007] The distance between the first bolt holes is equal to the distance between the second bolt holes;

[0008] The eye punch comprises a handle and a frustum-shaped working surface fixed at the front end of the handle, wherein the upper bottom diameter of the working surface is smaller than the hole diameter of the first bolt hole, and the lower bottom diameter is larger than the hole diameter of the first bolt hole.

[0009] Furthermore, the taper of the working surface is 2°.

[0010] Furthermore, the transition surface where the handle is connected to the working surface is connected via a rounded transition.

[0011] Furthermore, the eye punch also includes a hanging ring fixed on the handle.

[0012] Furthermore, the eye punch is processed by hot-rolled round steel bar machine.

[0013] Beneficial effects of the utility model:

[0014] The utility model has the advantages of simple structure, convenient and fast operation, safety and reliability. Construction personnel can quickly and accurately install the steel beam in place, and high-strength bolts can be quickly and smoothly inserted, thereby improving the installation quality and efficiency of the steel beam. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 This is a schematic diagram of the structure of the eye punch of the utility model;

[0017] Figure 3 This is a schematic diagram of the utility model in use. DETAILED DESCRIPTION

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings of the specification.

[0019] See also Figures 1 to 3 A positioning device for steel beam installation, comprising a group of first bolt holes 1 respectively opened at both ends of the web plate B of the steel beam A, a connecting rib plate 2 respectively welded to the inner side of two steel beam connecting columns C, a group of second bolt holes 3 opened on the connecting rib plate, a through-eye punch 4, a high-strength bolt 5 and a nut; the upper bottom diameter of the working surface is smaller than the hole diameter of the first bolt hole, and the lower bottom diameter is larger than the hole diameter of the first bolt hole, so that the bolts can be smoothly inserted into the bolt holes when aligned;

[0020] The through-eye punch includes a handle 41 and a frustum-shaped working surface 42 fixed at the front end of the handle. The aperture of the first bolt hole is between the upper and lower bottom diameters of the working surface. The through-eye punch and the bolt hole are transitionally matched. At the actual installation site, according to the specific size of the bolt hole, the through-eye punch can be adjusted to achieve transitional matching with the bolt hole by adjusting the length of the other side of the inserted bolt hole, so that one through-eye punch can be applied to bolt holes of different specifications; a hanging ring 43 can also be fixed on the handle of the through-eye punch for easy hanging, ensuring that it is easy to carry at high places to prevent falling from high altitudes. In order to reduce the friction between the through-eye punch and the bolt hole, the taper between the working surface and the surface and the axis is 2°, and the transition surface 44 connecting the handle and the working surface is connected by a rounded transition. The through-eye punch can be processed by a hot-rolled round steel bar machine. Its working surface surface is smooth and has low friction, which facilitates smooth insertion into the bolt hole during positioning.

[0021] The method of using the utility model is as follows:

[0022] like Figure 3As shown, a connecting rib plate is welded on the inner side of two steel beam connecting columns C, and a group of first bolt holes of the web plate B of the steel beam A are preliminarily aligned with a group of first bolts on the connecting rib plate. A through-eye punch is knocked into a bolt hole from one side of the steel beam using a hand hammer. Depending on the size of the cross-section of the steel beam, two or more through-eye punches can be knocked into each end of the steel beam when the cross-section is large. At this time, the bolt holes on the web plate of the steel beam and the connecting rib plate are basically aligned, and the steel beam is already in the actual installation position. Then, the matching high-strength bolts are inserted into the remaining bolt holes and fixed. Then, the through-eye punch is knocked out using a hand hammer, and then the position is supplemented with high-strength bolts and fixed with nuts. The installation of the steel beam is completed. The utility model can also be used in installation fields such as electromechanical equipment, process pipelines, etc. involving flange bolt connections.
