JP3002015U - Ramen Beam-to-column strain adjustment bolt - Google Patents

Abstract

(57) [Summary] [Purpose] Adjusting the strain between the columns of the rigid frame beam by combining the right screw left screw of the inner screw on the upper part of the bolt and the right screw left screw on both ends and combining the bolts with holes for turning the bolts. By using the bolts to correct the distortion of the building where the steel frame is being built, the inter-column dimensions of the building can be kept to the design dimensions, and the tiger wire is attached diagonally to the inside of the columns and the tension is adjusted to create the building. You can correct the erection of the building and build an accurate steel building that fits the design dimensions. [Structure] A bolt (1) with an internal right screw (2) on the top and a bolt (3) with an internal left screw (4) on the top, and (5) a right screw and a left screw. It is a ramen beam post-column distortion adjusting bolt that combines two holes for turning bolts in the middle with bolts, and a washer and nut in combination.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a ramen beam post-column distortion adjusting bolt that is a combination of bolts that are provided with right-handed and left-handed internal threads at the top of the bolts, and have right-handed and left-handed screws at both ends and holes for turning bolts .

[0002]

[Prior art]

 Conventionally, when repairing the distortion in steel frame construction, when adjusting the clearance of the rigid joint, a ball thin is hammered into the hole into which the bolt is inserted, or an iron wedge is inserted into the clearance to adjust the clearance. Since the wire was diagonally attached to the inside of the column to correct the strain, it lacked dimensional accuracy.

[0003]

[Issues to be solved by the device]

 This had the following drawbacks. (B) After the steel frame was erected and re-deformed, the dimensional accuracy between columns on each floor where the beams were installed was lacking. (B) During the re-distortion work, the tiger wire is stretched diagonally inside the pillar, so the connecting bolts and holes have a clearness of 1 mm to 1.5 mm. It is difficult to store accurately. (C) It is difficult to accurately control the building construction. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems]

 When assembling the steel frame, use the (2) and (4) (5) assembled ramen beam inter-column distortion adjustment bolt to the wave hole at the end of the ramen beam installed between the columns (1 ), Tighten the washer and tighten the nut, and at the same time, insert the bolt (3) into the beam at the end of the beam with the column and tighten the washer and tighten the nut. By adjusting the clearance with the beam, the dimension between columns can be reduced to the design size, and by adjusting the trawlers inside the column diagonally, the building can be accurately erected. The present invention is a ramen beam post-column strain adjustment bolt that allows the steel frame erection and assembly work to be carried out with the above configuration so that the dimensions without distortion can be reduced to the design dimensions.

[0005]

[Action]

 Insert the bolt (5) into the upper screw of the bolt (1) and the bolt (3), insert the bolt (1) into the wave hole at the end of the rigid frame beam, and insert the bolt (1) into the wave hole at the end of the beam with columns. By inserting the bolt (3) into it, tightening the washer and tightening it with the nut, and turning the bolt (5), the dimensions of the joints and columns of the ramen beam can be reduced to the design dimensions, and the distortion of the building can be accurately achieved. A bolt for adjusting the distortion between the columns and columns of the ramen that can be repaired.

[0006]

【Example】

 Hereinafter, examples of the present invention will be described. (A) Assemble the bolts (5) into the bolts (1), (3) upper inner screws (2), (4). (B) Insert the bolt (1) into the wave hole at the end of the rigid frame beam, similarly insert the bolt (3) into the wave hole at the end of the rigid frame beam with a column, insert a washer and tighten the nut. (C) Turn the bolts (5) to adjust the dimensions of the joints and columns of the rigid frame beam to the design dimensions. (D) The strain of the building can be corrected accurately by the way the tiger wire is stretched between the pillars. This plan has the structure as described above. When using it, when correcting the distortion of the building in the steel frame building assembly work, bolts (1), (3) upper internal screws (2), (4) Insert (5), insert bolt (1) into the end wave hole of the assembled rigid frame beam, insert bolt (3) into the end wave hole of the frame beam with columns, tighten the washer and tighten the nut, and then tighten the bolt (5). The distortion of the building can be corrected accurately by keeping the joint size of the rotating rigid frame beam and the dimensions between the columns to the design dimensions, and how to stretch the tiger wire between the columns.

[0007]

[Effect of device]

 In the steel frame assembling work, by using the ramen beam inter-column strain adjustment bolts to correct the distortion of the building, the inter-column dimensions of the building can be reduced to the design dimensions, and the distortion of the columns can be corrected accurately. There is no trouble with the construction, the fittings that will be attached later can be easily attached, and an accurate steel-framed building that meets the design dimensions can be created.
