Abstract

The utility model discloses a butt joint structure of a pipe truss or a circular pipe pillar. The butt joint structure of the pipe truss or the circular pipe pillar comprises circular pipes and lining pipes. A 45-degree inclined face is formed between an abutting end of each circular pipe and the axis of the circular pipe. The lining pipes are arranged inside the circular pipes, and the upper end of each lining pipe is arranged at a half length position of one inclined face. When an upper pillar and a lower pillar are connected in a butting mode, the upper pillar is pasted in from one side. The pasted-in portion has an angle smaller than the angle of a semi-circle, so that the construction difficulty is small. If the situation that 1-2 circular pipes in the 4 circular pipes are poor in size is encountered, and the 4 circular pipes cannot be normally pasted in completely, lifting lug clamping plates for aligning the circular pipes can be first fixed completely by bolts, external force or heat correction is applied to the circular pipes which cannot be pasted in so as to finish butt joint of the upper pillar and the lower pillar finally. The lining pipes of the upper column and the lower column are combined after installation is finished to enable the lining pipes to be arranged inside all welded seams, and welding of the welded seams can be smoothly finished equally. Simultaneous butt joint of a single circular pipe and even two ends of the pipe truss can be further achieved easily.

Description

Pipe truss or tubular pillar banjo fixing butt jointing structure

Technical field

The utility model belongs to the steel work processing technique field, is specifically related to manage truss or tubular pillar banjo fixing butt jointing structure.

Background technology

Relate to pipe truss or tubular pillar through regular meeting in steel work processing, less pipe truss can integral manufacturing, transportation, installation, and does not have too big difficulty.If it is bigger to run into scantling, perhaps weight is too big, after transportation, lifting are restricted, just need carry out segmentation to member, carries out assembly unit, welding to the job site.

Large-scale pipe truss leg field joint in the past, general upper prop is by the crane wire rope hanging, and member is sagging by the gravity freedom, and during butt joint, 4 pipes needs of last lower prop are aligning simultaneously, has one can not normally insert, and just can't finish the butt joint of lower prop.Because deviation is arranged was unavoidable to size during reality was produced, and in transportation distortion in various degree can take place also, so the field joint difficulty is bigger.

When single pipe or pipe truss needed two ends to dock simultaneously, the space that is not along the longitudinal movement was because general docking calculation need vertically move just along pipe and can finish butt joint, so can't finish the butt joint at two ends.

Summary of the invention

In order to overcome the above-mentioned defective that the prior art field exists, the purpose of this utility model is, a kind of pipe truss or tubular pillar banjo fixing butt jointing structure are provided, it is big to solve the pipe truss butt joint difficulty that prior art is big at connection dimension or weight is bigger, can't finish the problem that dock simultaneously at the pipe two ends in addition.

The pipe truss that the utility model provides or tubular pillar banjo fixing butt jointing structure, it comprises pipe and bushing pipe, and it is the inclined-plane of 45 that described pipe butt end is with the pipe axial line, and described bushing pipe is arranged on pipe inside, and its upper end is half extension position place on the inclined-plane.

Adopt the docking calculation of described pipe truss or tubular pillar banjo fixing butt jointing structure: adopt upper prop to be arranged on lower prop one side for the butt joint of pipe truss, and make the upper prop inclined-plane relative with the lower prop inclined-plane, upper prop moves horizontally the method for pasting lower prop then; Adopt upper prop to be arranged on two lower prop upsides for the butt joint of single pipe, and make the upper prop inclined-plane relative with two lower prop inclined-planes, upper prop vertically moves down the method for pasting two lower props then.

The pipe truss that the utility model provides or tubular pillar banjo fixing butt jointing structure, its beneficial effect be, during last lower prop butt joint, upper prop from a side paste into owing to paste all not enough semicircles of part, difficulty of construction is less; There is 1-2 to prop up the bad situation of size if run into 4 pipes, 4 pipes can not all normally paste into, after can be earlier all fixing with bolt the hanger clamping plate of alignment pipe, to can not paste into pipe apply external force or hot school, finally finish the butt joint of lower prop; The bushing pipe of going up lower prop after the installation combines, and makes whole weld seams inside that bushing pipe be arranged, and equally can finish the welding of weld seam smoothly; Butt joint when the utility model can also easily be realized single Zhi Yuanguan even pipe truss two ends.

Fig. 2 is the utility model pipe truss butt joint schematic diagram;

Fig. 3 is that schematic diagram is docked at the utility model tubular pillar two ends simultaneously.

Mark among the figure:

1. pipe; 2. bushing pipe; 3. upper prop; 4. lower prop; 5. upper prop; 6. lower prop.

The specific embodiment

With reference to the accompanying drawings, in conjunction with an embodiment, pipe truss or tubular pillar banjo fixing butt jointing structure that the utility model is provided are described in detail.

Embodiment

With reference to Fig. 1-Fig. 3, the pipe truss of present embodiment or tubular pillar banjo fixing butt jointing structure, it comprises pipe 1 and bushing pipe 2, it is the inclined-plane of 45 that described pipe 1 butt end is with pipe 1 axial line, described bushing pipe 2 is arranged on pipe 1 inside, and its upper end is half extension position place on the inclined-plane.

Adopt the docking calculation of described pipe truss or tubular pillar banjo fixing butt jointing structure: adopt upper prop 3 to be arranged on lower prop 4 one sides for the butt joint of pipe truss, and make upper prop 3 inclined-planes relative with lower prop 4 inclined-planes, upper prop 3 moves horizontally the method for pasting lower prop 4 then; Adopt upper prop 5 to be arranged on two lower prop 6 upsides for the butt joint of single pipe, and make upper prop 5 inclined-planes relative with two lower prop 6 inclined-planes, upper prop 5 vertically moves down the method for pasting two lower props 6 then.

Claims

1. a pipe truss or tubular pillar banjo fixing butt jointing structure, it comprises pipe and bushing pipe, it is characterized in that: it is the inclined-plane of 45 that described pipe butt end is with the pipe axial line, and described bushing pipe is arranged on pipe inside, its upper end is half extension position place on the inclined-plane.
