Description

Technical Field

[0001] The present invention relates to the field of steel structure connectors, and in particular to a combined steel frame angle locking connector. Background Art

[0002] Prefabricated steel structure buildings have inherent prefabrication advantages. Steel components are prefabricated in factories and installed on-site, which can increase construction speed. For large-span steel structure buildings, temporary support frames are required for steel trusses, extra-long and extra-heavy steel beams and other steel components that are hoisted in sections during the steel structure construction process to meet the requirements of high-altitude butt jointing.

[0003] The supporting structure generally adopts scaffolding, steel support frame and lattice support frame. This type of supporting structure is relatively scattered and needs to be spliced ​​and fixed one by one on site. In order to save construction time, prefabricated supporting structure has gradually been maturely applied. The prefabricated supporting structure is composed of multiple superimposed standard sections, and each standard section is composed of multiple standard parts. To build the supporting structure on site, you only need to enclose and fix the standard parts of each standard section, and then stack and fix each standard section.

[0004] The enclosure and fixation of standard parts of the prefabricated support structure, as well as the overlapping and fixing of each standard section, are all connected by bolts. The enclosure and fixation positions of the standard parts and the overlapping and fixation positions of the standard sections are converged into the same top angle area. This area requires a large number of holes for assembling bolts to be set on the surface of the standard parts, resulting in a sharp decrease in the structural strength of the support structure and prone to assembly errors, affecting assembly efficiency and stability. Summary of the Invention

[0005] In order to make up for the deficiencies of the existing technical problems, the purpose of the present invention is to provide a combined steel frame locking angle connector, which is used to solve the problem that the holes for assembly bolts provided in the connection area of ​​the prefabricated steel support structure are densely packed, resulting in reduced structural strength of the support structure and prone to assembly errors.

[0006] In order to solve the problems of the prior art, the technical solutions of the present invention are as follows:

[0007] A combined steel frame locking angle connector includes a backing plate with four inserting handles symmetrically distributed on the upper and lower surfaces of the backing plate. The backing plate is placed between the top corners of the upper and lower standard sections, and the inserting handles are respectively inserted into the vertical pole cavities of the standard parts.

The inner flat pressing part is flat against the inner side of the standard part. The upper and lower parts of the edge of the inner flat pressing part are provided with inner vertical folding ears, which clamp the inner side of the vertical pole of the standard part.

[0010] The outer plywood is arranged outside the standard section top angle. The two sides of the outer plywood are bent in a V shape to form an outer flat pressing part. The outer flat pressing part is flat against the outer sides of the two clamping plates. The inner plywood and the outer plywood are tightened by diagonal bolts.

[0011] Preferably, one side of the clamping plate has an outer vertical folding ear, which is clamped on the outer side of the vertical pole of the standard component, and the outer vertical folding ear and the inner vertical folding ear form a counter-pressure on the vertical pole of the standard component.

[0019] Preferably, the V-shaped angle of the inner flat pressing portion is 1-3° greater than the enclosed angle of the standard part, and the V-shaped angle of the outer flat pressing portion is 1-3° less than the enclosed angle of the standard part.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Combined steel frame locking angle connector, used for locking angle connection and fixing of steel support structure, such as Figure 1 As shown, the steel support structure is composed of multiple superimposed standard sections, each of which is enclosed by four standard parts. The standard parts are pre-welded together in the factory by vertical poles, horizontal poles, and diagonal webs. The locking angle connection part of the support structure is located at the converging top corner of the standard parts, which is the converging area of ​​the top corners of the four standard parts.

[0032] like Figure 4 As shown, the corner locking connector includes a backing plate 1, a clamping plate 2, an inner clamping plate 3, an outer clamping plate 4, and a diagonal bolt 5.

[0033] like Figure 4 As shown, the backing plate 1 is a flat plate with two ends extending perpendicularly to each other. Four plug handles 11 are fixedly welded to the upper and lower surfaces of the backing plate 1. The plug handles 11 are flat and have chamfered ends.

[0034] like Figure 4 、 Figure 6 As shown, two card plates 2 are provided, the main body of the card plate 2 is convex, the upper and lower parts of one side of the card plate 2 are bent to the same side to form a flat folding ear 22, the flat folding ear 22 extends horizontally, and the other side of the card plate 2 is bent 90° to form an outer vertical folding ear 21, and a cut is provided in the middle position of the outer vertical folding ear 21.

[0035] like Figure 4 、 Figure 7 As shown, both sides of the inner panel 3 are stamped and bent to form a V-shaped symmetrical inner flat-pressed portion 31, and the top and bottom edges of the inner flat-pressed portion 31 are bent to form inner vertical folding ears 32. The bending directions of the inner vertical folding ears 32 on the edges of the two inner flat-pressed portions 31 are perpendicular, and the surface of the inner panel 3 has two vertically extending waist-shaped holes.

[0036] like Figure 4 As shown, both sides of the outer cladding plate 4 are punched and bent to form a V-shaped symmetrical outer flat-pressed portion 41 , and the surface of the outer cladding plate 4 has two waist-shaped holes extending vertically.

[0037] The process of locking the angle of the steel frame support is as follows:

[0038] like Figure 2 、 Figure 3 、 Figure 5 As shown, the four standard parts of the lower standard section are enclosed, and a set of connecting parts is set at each top corner. The backing plate 1 is covered on the top corner surface of the standard part. The lower plug handle 11 is inserted into the cavity of the two adjacent standard part vertical poles. The plug handle 11 is inserted along the diagonal line of the standard part vertical pole cavity so that the plug handle 11 can stably position each standard part. Then, the bottom of the standard part of the upper standard section is inserted into the plug handle 11 on the top of the backing plate 1. At this time, the top corners of the four standard parts are gathered into one corner.

[0039] Place the two clamping plates 2 symmetrically and flatly on the surfaces of the standard parts on both sides, with the flat folding ears 22 clamping the horizontal bars of the upper and lower standard parts, and the outer vertical folding ears 21 clamping the sides of the upper and lower standard parts. Place the inner plywood 3 on the inner side of the top angle of the standard section, and the inner flat pressing part 31 is flat against the inner side of the standard part. The four inner vertical folding ears 32 are respectively clamped with the sides of the four standard parts. The inner vertical folding ears 32 and the outer vertical folding ears 21 form a counter-pressure on the standard parts.

[0040] The outer plywood 4 is set on the outside of the top angle of the standard section, and the outer flat pressing part 41 is flat against the outside of the two clamping plates 2. The two diagonal bolts 5 are passed through the waist-shaped holes on the surface of the inner plywood 3 and the outer plywood 4, and the inner plywood 3 and the outer plywood 4 are tightened. At this time, the inner flat pressing part 31 and the outer flat pressing part 41 press against the two sides of the standard part vertical pole, and the inner vertical folding ear 32 and the outer vertical folding ear 21 press against the other two sides of the vertical pole, so that the plane of the vertical pole is tightened and aligned, and the horizontal position of the standard part is locked by holding the horizontal bar with the flat folding ear 22, so that the top angle positions of the four standard parts are automatically aligned and locked.

[0041] like Figure 3 As shown, the end of the inner vertical folding ear 32 is bent outward in a circuitous manner, so that the end surface of the inner vertical folding ear 32 forms a frame surface. When the inner vertical folding ear 32 is laterally flat against the column, its frame surface is pressed against the outer side of the flat folding ear 22, applying a shaping force to the flat folding ear 22, thereby improving the stability of locking the standard part in the vertical direction.

[0042] The V-shaped angle of the inner flat pressing part 31 is 1-3° greater than the enclosed angle of the standard part, and the V-shaped angle of the outer flat pressing part 41 is 1-3° less than the enclosed angle of the standard part. When the inner and outer clamping plates 3 and 4 are tightened by the diagonal bolts 5, the inner and outer flat pressing parts 31 and 41 resist micro-deformation, thereby increasing the clamping force on the standard part and improving the locking stability effect of the standard part.

[0043] The ends of the outer vertical folding ears 21 and the flat folding ears 22 have rounded corners, which facilitate the outer vertical folding ears 21 and the flat folding ears 22 to be clamped on the outside of the horizontal rod and the vertical rod.

[0044] like Figure 2 、 Figure 3 、 Figure 4 As shown, the two sides of the end of the pad 1 have protruding buckling parts 12, the buckling part 12 on the inner side of the pad 1 is clamped on the edge of the inner flat pressing part 31, the surface of the clamping plate 2 has a bite opening 23, and the buckling part 12 on the outer side of the pad 1 clamps the bite opening 23, thereby improving the bonding strength between the pad 1 and the clamping plate 2 and the inner clamping plate 3, and maintaining good restraining force between the various components.

[0045] If the weight of the steel structure carried by the steel frame support is large or the supporting structure extends too high, it is necessary to increase the fixing strength of the connection point. Reinforcement bolts 6 can be set through the outer flat pressing part 41, the clamping plate 2, the standard part vertical pole, and the inner flat pressing part 31. Four reinforcement bolts 6 are set for the four standard parts, which can effectively improve the locking strength of the assembly node.

[0046] like Figure 3 As shown, the reinforcing bolts 6 and the diagonal bolts 5 are located on two vertical planes. Both the reinforcing bolts 6 and the diagonal bolts 5 are penetrated from the inside of the standard section to the outside and then the nuts are tightened. The hexagonal ends of the reinforcing bolts 6 and the diagonal bolts 5 on the inside are in contact with each other, which can reduce the loosening range of the reinforcing bolts 6 and the diagonal bolts 5 and improve the connection stability.

[0047] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
