Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and specifically refers to a freely adjustable and steerable prefabricated frame. Background Technology

[0002] As the complexity of steel structure designs increases, installation becomes significantly more challenging, especially for large-span and irregularly shaped structures. These often require assembly on ground-based jigs before high-altitude hoisting. During construction, adjustments to the dimensions of individual sections are necessary based on the building's appearance and site conditions, necessitating changes to the jig dimensions. Traditional jigs, with their fixed dimensions, offer limited adjustability, involve complex assembly processes, and struggle to control installation accuracy, failing to meet turnaround requirements and resulting in substantial material waste. Therefore, there is an urgent need to design a freely adjustable and easily assembled jig. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a freely adjustable and steerable prefabricated jig that can flexibly adjust its geometric dimensions according to site conditions, allowing for quick, convenient, and efficient assembly, and meeting the requirements for splicing and installation accuracy.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A freely adjustable and steerable prefabricated jig includes: jig column splicing unit, column end plate, column, first high-strength bolt, extended high-strength screw, column base plate, support assembly, second high-strength bolt, support column, support base, support bracket, jig crossbeam, and crossbeam adjustment hole.

[0006] Furthermore, the freely adjustable and steerable prefabricated frame column is composed of column splicing units, which consist of column end plates, columns, and first high-strength bolts. The column end plates are welded to both sides of the column, and two column splicing units are connected to the column end plates by the first high-strength bolts. Bolt holes are opened on the column end plates, and a column base plate is welded on the bottom column.

[0007] Furthermore, the height adjustment of the freely adjustable and steerable assembled jig is achieved through an extended high-strength screw and an adjusting nut. The extended high-strength screw has threads, and its upper end passes through the column end plate, and its lower end also passes through the column end plate. The adjusting nut is then connected to the extended high-strength screw and pressed against the column end plate. When height adjustment is required, the adjusting nut is twisted up and down to change the height of the jig column.

[0008] Furthermore, the freely adjustable and steerable prefabricated frame is equipped with a frame crossbeam, wherein a number of crossbeam adjustment holes are equally spaced on the frame crossbeam, the number of which is determined according to the block size of the project.

[0009] Furthermore, each crossbeam of the freely adjustable and steerable assembly frame is provided with a support assembly, which is connected and fixed to the crossbeam of the frame by a second high-strength bolt.

[0010] Furthermore, the support assembly consists of a support column, a support base, and a support bracket, wherein the support brackets are symmetrically welded to the support column, the support base is welded to the bottom of the support column, and the support base has holes for fixing to the frame beam with a second high-strength bolt.

[0011] Furthermore, the support assembly can move on the crossbeam of the jig by aligning with the crossbeam adjustment holes at different positions. The support assembly can also be rotated 90 degrees according to the needs of the actual engineering project block size, and then connected and fixed to the crossbeam of the jig by a second high-strength bolt.

[0012] The freely adjustable and steerable assembled jig provided by this utility model has at least the following advantages compared to existing systems:

[0013] (1) The height of the frame column can be adjusted by lengthening the high-strength screw and adjusting the nut to meet the assembly requirements of steel structures of different heights and dimensions.

[0014] (2) The support components provided by this utility model can move and turn freely on the crossbeam of the frame, which can meet the requirements of steel structure assembly of different widths when splicing the frame.

[0015] (3) This utility model is simple and quick to assemble, easy to disassemble, and can be reused. It can be used for the assembly of trusses and irregular steel structures. Attached Figure Description
