Abstract
The utility model relates to the segment fastening and connection technology in construction of arched buildings, such as subways, culverts, tunnels and the like, in particular to a circumferential and longitudinal segment fastener, which comprises bolts, nuts and gaskets, wherein the bolts take the shapes of circular arcs, the radius of each circular arc is 260mm to 560mm, and the radian is 60 degrees to 100 degrees. Compared with the traditional connection method of segments, the circumferential and longitudinal segment fastener with simple structure, practicability, high strength, and strong corrosion resistance has the advantages that the labor and material can be saved, and the installation can be carried out conveniently at a high speed, so that the construction period can be greatly shortened, the work intensity can be reduced for workers, the efficiency can be improved, and the construction cost can be lowered for enterprises.
Description
Technical field:
The utility model relates to the technology that is fastenedly connected of the section of jurisdiction in the construction of arcuated constructions such as subway, culvert, tunnel, is specifically related to the vertical section of jurisdiction of a kind of ring fastening piece.
Background technique:
At present, in the construction of arcuated constructions such as subway, culvert, tunnel, generally adopt the method for pipe sheet assembling, quality of connection between the section of jurisdiction, directly the service property (quality) in tunnel, back is built up in influence, and the main dependence that is fastenedly connected between present stage such as working life section of jurisdiction is welded and is finished, but this kind Placement, construct very inconvenient, time-consuming, take material, installation rate is slow, long in time limit, the construction cost height, and its intensity is also unsatisfactory, corrosion-resistant.
The model utility content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides the vertical section of jurisdiction of a kind of ring fastening piece, it is simple in structure, and is practical, and intensity height, corrosion resistance are strong, compare with the connecting means of section of jurisdiction in the past have the saving of labor, material-saving, easy for installation, advantage such as installation rate is fast, thereby the reduction of erection time is reduced working strength of workers, reduces the cost of enterprise.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The vertical section of jurisdiction of a kind of ring fastening piece, it comprises bolt 3, nut 5 and packing ring 4, wherein: described bolt 3 is circular-arc.
Further, the radius of described circular-arc bolt 3 is 260mm～560mm, and its radian is 60 degree～100 degree.
The beneficial effects of the utility model are:
The utility model is simple in structure, and is practical, and intensity height, corrosion resistance are strong, compare with the connecting means of section of jurisdiction in the past have the saving of labor, material-saving, easy for installation, advantage such as installation rate is fast, thereby the reduction of erection time is reduced working strength of workers, reduces the construction cost of enterprise.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 be the utility model with the section of jurisdiction outside the structural representation that is connected;
Fig. 3 be the utility model with the section of jurisdiction in the structural representation that is connected;
Fig. 4 is the partial enlarged drawing of A among the utility model Fig. 3.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model comprises bolt 3, nut 5 and packing ring 4, described bolt 3 is circular-arc, its radius of arc is 260mm～560mm, and its radian is 60 degree～100 degree, in the present embodiment, the strength grade of bolt 3 is 10.9 grades, zinc-plated processing is carried out on its surface, and its radius is 380mm, and its radian is 94 degree.
As shown in Figure 2, when outside adopt section of jurisdiction 1, connecting, bolt block 2 is set respectively on the outer surface of two adjacent sections of jurisdiction 1, bolt 3 is passed bolt block 2, load onto packing ring 4 and nut 5 then, fastening nut 5, thus the ring of having realized section of jurisdiction 1 vertically connects.
As shown in Figure 3, Figure 4, when in adopt section of jurisdiction 1, connecting, bolt hole 7 and hand hole 6 are set respectively on the internal surface of two adjacent sections of jurisdiction 1, bolt 3 is passed bolt hole 7, load onto packing ring 4 and nut 5 then, fastening nut 5, thus the ring of having realized section of jurisdiction 1 vertically connects.
