Abstract
The utility model provides a compound section of jurisdiction of modified structure, including concrete layer, steel deck, pre -buried steel sheet, dowel, first screw, second screw, fixing bolt, all being equipped with the steel deck on section of jurisdiction concrete layer's interior cambered surface, extrados and the concatenation face, being equipped with pre -buried steel sheet in the concrete layer, the surface of pre -buried steel sheet and concrete layer's exterior facial features flush, pre -buried steel sheet is connected in the inside dowel anchor of concrete layer with setting up, be equipped with first screw on the pre -buried steel sheet, be equipped with the second screw on the steel deck, fixing bolt can pass the second screw in proper order, first screw is fixed the steel deck on concrete layer. The beneficial effects of the utility model are that the rigidity of section of jurisdiction is big, and tunnel construction stability is high.
Description
Technical field
This utility model belongs to section of jurisdiction technical field, especially relates to the multiple tube chip architecture of a kind of improvement.
Background technology
Existing section of jurisdiction is mostly xoncrete structure, transport transport process is susceptible to collide with, damages the original shape in section of jurisdiction and structure so that it is field of load reduces, and the section of jurisdiction rigidity of concrete is low, the multiple tube chip architecture that a kind of stability is high needs to research and develop further.
Utility model content
The multiple tube chip architecture of the improvement that the purpose of this utility model is to provide a kind of simple in construction, simple to operate, stability is high.
The technical solution of the utility model is: the multiple tube chip architecture of a kind of improvement of the present utility model, including concrete layer, steel plate layer, pre-embedded steel slab, dowel, the first screw, the second screw, fixing bolt；
It is equipped with steel plate layer on intrados, extrados and the Mosaic face of described section of jurisdiction concrete layer, pre-embedded steel slab it is provided with in concrete layer, the outer surface of pre-embedded steel slab and the outer surface of concrete layer flush, described pre-embedded steel slab and be arranged on the dowel anchor connection within concrete layer；
Described pre-embedded steel slab is provided with the first screw, and described steel plate layer is provided with the second screw, and described fixing bolt can sequentially pass through the second screw, steel plate layer is fixed on concrete layer by the first screw.
Preferably, described concrete layer, steel plate layer are provided with the slip casting passage communicated, and the end of described slip casting passage is provided with dismountable sealing-plug.
This utility model has the advantage that with good effect: 1, owing to using technique scheme, and the transport construction of section of jurisdiction is convenient；Having simple in construction, simple to operate, rigidity is big, prevents advantages such as colliding with.
2, pre-embedded steel slab and the dowel anchor connection that is arranged in concrete layer, improve the fix tightly stability of pre-embedded steel slab, can effectively prevent from coming off.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-concrete layer, 2-steel plate layer, 3-pre-embedded steel slab, 4-dowel, 5-the first screw, 6-the second screw, 7-fixes bolt, 8-slip casting passage, 9-sealing-plug.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is elaborated.
As it is shown in figure 1, the multiple tube chip architecture of a kind of improvement of the present utility model, including concrete layer 1, steel plate layer 2, pre-embedded steel slab 3, dowel the 4, first screw the 5, second screw 6, fixing bolt 7；
It is equipped with steel plate layer 2 on intrados, extrados and the Mosaic face of described section of jurisdiction concrete layer 1, pre-embedded steel slab 3 it is provided with in concrete layer 1, the outer surface of pre-embedded steel slab 3 and the outer surface of concrete layer 1 flush, described pre-embedded steel slab 3 and be arranged on dowel 4 anchor connection within concrete layer 1；
Described pre-embedded steel slab 3 is provided with the first screw 5, and described steel plate layer 2 is provided with the second screw 6, and described fixing bolt 7 can sequentially pass through second screw the 6, first screw 5 and steel plate layer 2 is fixed on concrete layer 1.
Described concrete layer 1, steel plate layer 2 are provided with the slip casting passage 8 communicated, and the end of described slip casting passage 8 is provided with dismountable sealing-plug 9.
The work process of this example: the steel plate layer 2 arranged on the intrados of section of jurisdiction concrete layer 1, extrados and Mosaic face can be effectively improved the rigidity of tunnel segment structure, it is simple to constructing in section of jurisdiction, can effectively reduce construction costs, reduction of erection time.
With the setting of the pre-embedded steel slab 3 of screw, relative to the set-up mode of embedded nut, it is to avoid appearance caducous problem, pre-embedded steel slab 3 is anchored by dowel 4, fixing more stable.
The setting of slip casting passage 8, can improve, to carrying out high-pressure slip-casting between section of jurisdiction and lithosphere, the safety coefficient that tunnel construction runs.
The setting of sealing-plug 9, has waterproof effect.
Above an embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All impartial changes made according to this utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
