Description
Technical field
The present invention relates to mechanical engineering field, be specifically related to a kind of pre-buried channel flow fixation kit.
Background technology
Pre-buried channel flow can be applied in the occasions such as track traffic, high ferro, building.Pre-buried channel flow in track traffic in Shield-bored tunnels section of jurisdiction is on mould, and the requirement fixing for laminating is very strict.There is multiple fixed form in prior art, but does not also have at present a kind of conduit that can solve completely to fit on segment die fixing method, and such as, existing laminating fixed form exists following problem:
The first, adopt reinforcement welding mode to there is difficulty of construction large, and easily cause unnecessary damage to conduit surface; And when section of jurisdiction is built, the existence due to external vibrator makes conduit and die surface depart from, and cannot reach the pre-buried effect of expectation.
The second, adopt in spot welding conduit fixed form, spot welding all causes certain damage to conduit and segment die; In addition, need first on mould, to carry out conduit location before spot welding, also will polish to mould before by the time next time pre-buried, construction is complicated, cannot efficiently construct.In addition, the position of spot welding and size are manual controls, may cause tunnel segment demoulding difficulty like this.
In addition, when being fixed by above-mentioned method, conduit is covered by section of jurisdiction cement, can not effectively fit when laminating is fixing, after making section of jurisdiction shaping, the conduit be embedded in section of jurisdiction is covered by cement, removes covering conduit wash cement time-consuming, and unsightly, also affect the installation of later stage standing finish; Conduit is fitted fixing on mould, and working space is little, and easily pollutes template face; Template Location precision needs repeated examinations, and also easily produce displacement in concreting process.
Utility model content
The object of this invention is to provide a kind of pre-buried channel flow assembly, the problem that can not meet the demands is fixed in the laminating existed to solve prior art.
For achieving the above object, the invention provides a kind of pre-buried channel flow fixation kit, fit for pre-buried channel flow and segment die are fixed, described segment die has locating hole, described pre-buried channel flow bottom has longitudinal opening, described pre-buried channel flow back has datum hole, described locating hole inwall is provided with screw thread, described fixation kit comprises alignment pin, connecting thread bar and clamping cap, described alignment pin is hollow structure, internal edge is provided with screw thread, described clamping cap comprises the connecting rod and stubborn cap integrally cast, hollow below described connecting rod, and inside has screw thread, described connecting thread bar outer rim arranges screw thread, described alignment pin lower end is screwed onto in the locating hole of described segment die, the described connecting rod of described clamping cap penetrates from the datum hole at the back of institute's pre-buried channel flow, be spirally connected with one end of described connecting thread bar, the other end and the described alignment pin of described connecting thread bar are spirally connected, and it is outside that described stubborn cap is stuck in described pre-buried channel flow.
According to the pre-buried channel flow fixation kit described in the embodiment of the present invention, the top of described stubborn cap is horizontal stripe shape.
According to the pre-buried channel flow fixation kit described in the embodiment of the present invention, the size of described stubborn cap is greater than the size of the described datum hole at described pre-buried channel flow back.
The fixation kit that the embodiment of the present invention provides, due to conduit, on mould, adopt alignment pin fixture to fit fixing, conduit and segment die laminating degree good, demoulding rear slot track is concordant with concrete surface, simple and direct attractive in appearance, improves pre-buried quality.

Fig. 1 is the assembled state figure of pre-buried channel flow fixation kit provided by the invention;
Fig. 2 A is a side sectional view of clamping cap in the present invention;
Fig. 2 B is another side sectional view of clamping cap in the present invention.
Detailed description of the invention
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
As shown in Figure 1, the invention provides a kind of pre-buried channel flow fixation kit, for pre-buried channel flow 10 is fitted with segment die 20 is fixing, described segment die 20 has locating hole 21, the inwall of locating hole 21 is provided with screw thread, described pre-buried channel flow bottom has longitudinal opening 12, described pre-buried channel flow 10 back has datum hole 11, described fixation kit comprises alignment pin 31, connecting thread bar 32 and clamping cap 33, described alignment pin 31 is hollow structure, and internal edge is provided with screw thread, and described connecting thread bar 32 outer rim arranges screw thread;
As shown in Figure 2 A and 2B, described clamping cap 33 comprises the connecting rod 331 and stubborn cap 332 integrally cast, hollow below described connecting rod 331, and inside has screw thread.For the ease of fixing, horizontal stripe shape is arranged to, so that tighten in the top of described stubborn cap 332.
With further reference to Fig. 1, described alignment pin 31 lower end is screwed onto in the locating hole 21 of described segment die 20, the described connecting rod 331 of described clamping cap 33 penetrates from the datum hole 11 at the back of institute's pre-buried channel flow 10, be spirally connected with one end of described connecting thread bar 32, the other end and the described alignment pin 31 of described connecting thread bar 32 are spirally connected, size due to described stubborn cap 332 is greater than the size of the described datum hole 11 at described pre-buried channel flow 10 back, and it is outside that described stubborn cap 332 is stuck in described pre-buried channel flow 10.
