Description

Technical Field

[0001] The present invention relates to the technical field of steel structure beams and columns, in particular to auxiliary reinforcement equipment for large-scale steel structure nodes. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welding, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields.

[0003] When assembling steel structures, steel beams and steel columns need to be spliced ​​together (such as Figure 8 The traditional splicing method requires the use of clamping equipment to clamp the steel beams and steel columns separately, and the clamping position needs to be adjusted according to the splicing position. Then, the position of the clamped steel beams and steel columns is adjusted to adjust the position of the spliced ​​nodes again. Multiple adjustment steps are required to make the steel beams and steel columns in the center position. However, this multiple adjustment method is very likely to result in inaccurate node positions after splicing. In addition, since the steel beams and steel columns are only slightly in contact at the junction, it is easy to cause the nodes to loosen during subsequent welding or bolt connection, affecting the firmness of the steel structure nodes. Summary of the Invention

[0004] The present invention provides an auxiliary reinforcement device for large-scale steel structure nodes, which solves the technical problems that the existing steel structure needs to adjust its position multiple times before assembly, is very prone to inaccurate splicing, and the steel beams and steel columns are only in slight contact, which affects the firmness of the steel structure nodes during subsequent welding or bolt connection.

[0008] In one possible implementation, the tightening assembly includes a folding plate that is symmetrically fixedly connected to the upper end face of the support in the front and rear directions, the folding plate consists of a vertical section and an inclined section fixedly connected to the upper part of the vertical section, the front end face of the folding plate is provided with a strip-shaped through groove for the mounting rod to extend into, the outside of the mounting rod is symmetrically slidably connected to the front and rear directions with a circular ring corresponding to the folding plate, and a top spring is provided on the outside of the mounting rod and located between the circular ring and the semicircular clamping column.

[0009] In one possible implementation, rectangular frames are embedded in opposite sides of the two adjacent semicircular clamping columns in the front and rear, and a number of longitudinal grooves are equidistantly provided on the upper and lower opposite sides of the rectangular frame. The upper and lower opposite longitudinal grooves are connected to each other by a wheel column through a sliding block, and a limiting spring is fixedly connected between the longitudinal groove wall and the sliding block.

[0010] In a possible implementation, a positioning strip is fixedly connected to the outside of the mounting rod along its axial direction, and the semicircular clamping column is penetrated by the mounting rod and has an inner wall provided with a positioning groove for cooperating with the positioning strip.

[0014] In the present invention, the folding plate and the circular ring in the tightening assembly cooperate with each other to drive the semicircular clamping columns to move closer to each other, so that the steel beam can be quickly clamped, and then the L-shaped top plate and the inclined pressure plate in the tightening assembly cooperate with each other to push the steel beam against the steel column, so that the steel beam and the steel column can be tightly spliced ​​together, thereby strengthening the stability of the joint between the steel beam and the steel column.

[0027] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] See also Figure 1 The present invention provides a technical solution: an auxiliary reinforcement device for a large steel structure node, comprising a support 1, a longitudinal positioning mechanism 2 for positioning a steel column installed in the middle of the upper end surface of the support 1, and a transverse positioning mechanism 3 for positioning a steel beam installed symmetrically on the left and right upper end surface of the support 1.

[0030] The two ends of the steel column are respectively sleeved on the outside of the two load-bearing rods 22.

During the downward movement of the push frame 24, it moves on the inclined surface of the right-angle plate 25, and then moves towards the steel column under the extrusion of the inclined surface of the right-angle plate 25 until the two push frames 24 in the front and rear positions both hit the ends of the steel column, thereby clamping the steel column and adjusting its position at the same time, so that the steel column is in a centered position, which is convenient for the accuracy of the node when it is subsequently connected to the steel beam.

The outside of the mounting rod 32 is symmetrically slidably connected with a circular ring 342 corresponding to the folding plate 341. A top spring 343 is sleeved on the outside of the mounting rod 32 and located between the circular ring 342 and the semicircular clamping column 33.

[0032] See also Figure 4 、 Figure 5 and Figure 6 The two adjacent semicircular clamping columns 33 in the front and rear are embedded with rectangular frames 4 on the opposite sides, and a number of longitudinal grooves 5 are equidistantly provided on the upper and lower opposite sides of the rectangular frame 4.

[0034] During operation, the steel column is first placed in the longitudinal positioning mechanism 2 by the external clamping equipment, and the two ends of the steel column are respectively sleeved on the outside of the two load-bearing rods 22, and then the load-bearing rod 22 is pressed down under the dead weight of the steel column. During the descending process of the load-bearing rod 22, the push frame 24 and the inclined surface of the right-angle plate 25 cooperate with each other to push the steel column to the center position, and at the same time, the steel column can be clamped.
