Description
Technical field
The utility model relates to mechanical engineering field, is 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, very strict for the requirement that laminating is fixing.There is multiple fixed form in prior art, but does not also have at present a kind ofly can solve the conduit fixing method of fitting completely on segment die, and for example, existing laminating fixed form exists following problem:
The first, adopts reinforcing bar welding manner to exist difficulty of construction large, and easily unnecessary damage is caused in conduit surface; And while building in section of jurisdiction, because the existence of external vibrator makes conduit and die surface, depart from, cannot reach the pre-buried effect of expectation.
The second, adopts in spot welding conduit fixed form, and 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 like this tunnel segment demoulding difficulty.
In addition, while being fixed by above-mentioned method, conduit is covered by section of jurisdiction cement, while fitting fixedly, can not effectively fit, make after the moulding of section of jurisdiction, the conduit being embedded in section of jurisdiction is covered by cement, removes covering conduit wash cement time-consuming, and not attractive in appearance, 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; In Template Location precision, need repeated examinations, and also easily produce displacement in concreting process.
Utility model content
The purpose of this utility model is to provide a kind of pre-buried channel flow assembly, the fixing problem that can not meet the demands of laminating existing to solve prior art.
For achieving the above object, the utility model provides a kind of pre-buried channel flow fixation kit, for pre-buried channel flow and segment die are fixed to laminating, on described segment die, there is 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 connecting rod and the stubborn cap that one is cast, described connecting rod below is hollow, 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 of described connecting thread bar and described alignment pin 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 utility model embodiment, the top of described stubborn cap is horizontal stripe shape.
According to the pre-buried channel flow fixation kit described in the utility model embodiment, 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 utility model embodiment provides, because conduit adopts the laminating of alignment pin fixture fixing on mould, conduit and segment die laminating degree are good, and demoulding rear slot track is concordant with concrete surface, simple and direct attractive in appearance, has improved pre-buried quality.
Accompanying drawing explanation
The assembled state figure of the pre-buried channel flow fixation kit that Fig. 1 provides for the utility model;
Fig. 2 A is a side sectional view of clamping cap in the utility model;
Fig. 2 B is another side sectional view of clamping cap in the utility model.
The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the utility model provides a kind of pre-buried channel flow fixation kit, for pre-buried channel flow 10 is fitted with segment die 20 is fixing, on described segment die 20, there is 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 backs have 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 rims arrange screw thread;
As shown in Figure 2 A and 2B, described clamping cap 33 comprises connecting rod 331 and the stubborn cap 332 that one is cast, and described connecting rod 331 belows are hollow, and inside has screw thread..For the ease of fixing, horizontal stripe shape is arranged in the top of described stubborn cap 332, so that tighten.
With further reference to Fig. 1, described alignment pin 31 lower ends are 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 of described connecting thread bar 32 and described alignment pin 31 are spirally connected, because the size of described stubborn cap 332 is greater than the size of the described datum hole 11 at described pre-buried channel flow 10 backs, described stubborn cap 332 is stuck in described pre-buried channel flow 10 outsides.
