Description
Technical field
The utility model relates to a kind of Demountable assemble type back cords for dies plate tap, belong to Building technology neck
Domain.
Background technique
Back cord, usually group welding piece, as shown in Figure 1, 2, it is mainly by two long rectangular steel pipes parallel, spacing is certain
11, it is linked together in a welding manner by multiple short rectangular steel pipes 12.The spacing of each short rectangular steel pipe 12 is larger, and in rule
Rule property.Since the operating condition in engineering is complicated and changeable, the case where short rectangular steel pipe 12 is with conflicting to wire drawing bar frequent occurrence, lead to mould
The process of plate installation is affected.When welding capacity is big, back cord deforms frequent occurrence, needs to increase trimming.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide that a kind of structure is simple, and installation makes
With convenient, easy to assembly quick, high-efficient, back cord high yield rate, can Reusability, reduce the Demountable assemble type of use cost
Back cord.
The purpose of this utility model is completed by following technical solution, a kind of detachable assembled back cord, it is wrapped
Two spaced apart, parallel arrangement long rectangular steel pipes are included, spacing certain distance is symmetrical on the long rectangular steel pipe
It is provided with through bolt hole, wears corresponding to described Dui and is equipped with a short round tube between two long rectangular steel pipes of bolt hole, described two
Long rectangular steel pipe is secured with nuts after passing through the through bolt hole and the short round tube of centre by corresponding bolt.
As preferred: the two root longs rectangular steel pipe middle ware is equipped with the short round tube, and the distance at interval is short circle
The length of pipe, the bolt penetrates from the bolt hole on the outside of a wherein root long rectangular steel pipe, after the short round tube from
Another through bolt hole of root long rectangular steel pipe is pierced by, and is secured with nuts；According to 600-on the two root longs rectangular steel pipe
Multiple uniformly distributed, through bolts hole are arranged in the gap length of 1000mm.
The utility model has structure simple, easy to install and use, easy to assembly quick, high-efficient, back cord high yield rate,
Can Reusability, reduce use cost the features such as.
Detailed description of the invention
Fig. 1 is existing back cord structural schematic diagram.
Fig. 2 is the A direction view of Fig. 1.
Fig. 3 is the structural schematic diagram of the utility model.
Fig. 4 is the B direction view of Fig. 3.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: Fig. 3, shown in 4, one kind described in the utility model
Detachable assembled back cord, it includes two spaced apart, parallel arrangement long rectangular steel pipes 21, the long rectangle
Spacing certain distance is symmetrically arranged with through bolt hole 22 on steel pipe 21, and two long rectangles of bolt hole 22 are worn corresponding to described pair
A short round tube 23 is equipped between steel pipe 21, the two long rectangular steel pipe 21 passes through the through bolt by corresponding bolt 24
It is fixed with nut 25 after the short round tube 23 of hole 22 and centre.
As shown in the figure, two root longs rectangular steel pipe, 21 middle ware is equipped with the short round tube 23, and the distance at interval is
The length of short round tube 23, the bolt 24 penetrate, from the bolt hole 22 in wherein 21 outside of a root long rectangular steel pipe by described
Short round tube 23 after be pierced by from the through bolt hole 22 of another root long rectangular steel pipe 21, and it is fixed with nut 25；Two root long
Multiple uniformly distributed, through bolts hole 22 are set according to the gap length of 600-1000mm on rectangular steel pipe 21, preferably
800mm gap length.
The utility model during the installation process, if interfering to wire drawing bar and short round tube, can remove bolt and nut immediately
With short round tube, the hole location on side is changed to；Welding is eliminated, the possibility of welding deformation is also just reduced；Assembling does not need very high
Technology content, it is convenient and efficient, it is high-efficient；Back cord high yield rate and can Reusability.
