Abstract
The utility model discloses a joint sealing structure for construction prefabricating structure assembling steel bundle pipeline, comprising a construction prefabricating structure (1) and a construction prefabricating structure (2). The construction prefabricating structure (1) and the construction prefabricating structure (2) are respectively provided with a prefabricating pipe (5) and a prefabricating pipe (6) used to draw the pre-stress steel bundle. The opening of the prefabricating pipe (5) and the opening of the prefabricating pipe (6) are closed together, which is characterized in that the closing openings of the prefabricating pipe (5) and the prefabricating pipe (6) are respectively provided with a seal ring (3) and a seal ring (4) in different flexibility. The utility model can seal well the prefabricating pipe so as to ensure the quality of grout injection construction in vacuum grouting construction.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction of building prefabrication structure "assembling steel bundle pipelin seam crossing.
Background technology
The building prefabrication structure is by reserving pipeline in precast construction, during assembly unit the steel bundle is passed this reservation pipeline and stretch-draw prestressing force, making precast construction be linked to be integral body when adopting assembling technique to connect.For making steel bundle and member form one and preventing that the steel bundle in the pipeline is corroded in daily use, behind steel Shu Jinhang stretch-draw prestressing force, need in reserving pipeline, to make grouting treatment in the work progress.When being in the milk, for guaranteeing that grouting can be full of whole pipe, generally adopt vacuum grouting technology to carry out, so just require adjacent two precast constructions to seal at the seam crossing of pipeline splicing place, to reach the technological requirement of vacuum grouting, generally be to add a sealing ring therefore at seam crossing.
The sealing ring that uses is a rubber ring or foamed plastics circle at present, though can play certain sealing function, because its sealing performance is relatively poor, in the work progress of construction site, still can not reach the better seal effect, influences the vacuum grouting quality.
Summary of the invention
The utility model provides a kind of sealing performance quality hermetically-sealed construction fabulous, that can guarantee vacuum grouting at above-mentioned building prefabrication structure existing foregoing problems in the steel beam tube road seal process when the assembly unit.Described hermetically-sealed construction is made up of two sealing rings, described two sealing rings are made by different materials, have different degree of flexibility, stick on respectively on the pipeline opening of two relative reservation pipelines of adjacent two precast constructions, like this, when assembly unit, two sealing rings abut against together, to being through after wherein steel bundle adds prestressing force, the reservation pipeline that assembly unit is connected can reach fabulous sealing effectiveness.
Description of drawings
Below, the joint seal structure to building prefabrication structure "assembling steel bundle pipelin of the present utility model is described further in conjunction with the accompanying drawings.In the accompanying drawing:
Fig. 1 is the joint seal structure section figure of the utility model building prefabrication structure "assembling steel bundle pipelin.
The specific embodiment
Accompanying drawing 1 has disclosed a kind of embodiment of the present utility model.As shown in Figure 1, precast construction 1 and precast construction 2 are two adjacent building prefabrication structures, be useful on respectively in the described building prefabrication structure 1 and 2 and wear the reservation pipeline 5 and 6 that draws the steel bundle, described two adjacent building prefabrication structures 1 and 2 are in the butt joint of A place, and the opening of the described reservation pipeline 6 of the opening of described reservation pipeline 5 is relative at this moment.At the opening part of described reservation pipeline 5 and the opening part of described reservation pipeline 6 sealing ring 3 and 4 are set respectively, described two sealing rings 3 and 4 are made by different materials, have different degree of flexibility, can stick on each self-corresponding pipeline tapping place, also can be placed on each self-corresponding pipeline tapping place and push down by two the building prefabrication structures 1 and 2 that are close together.Then the steel bundle that is through is wherein added prestressing force, described building prefabrication structure 1 and 2 is pressed together by described sealing ring 3 and 4, the reservation pipeline that assembly unit is connected plays fabulous sealing effectiveness, thereby guarantees the grouting construction quality in the vacuum grouting construction.Described sealing ring 3 and 4 can be made by rubber and foamed plastics respectively.
Abovely just the joint seal structure of the utility model building prefabrication structure "assembling steel bundle pipelin is described in detail in conjunction with preferable enforcement.But for the those of ordinary skill of present technique field; obviously can understand foregoing description without limits to protection domain of the present utility model; for example; in connotation scope of the present utility model, can adopt the sealing ring of different materials system according to the actual conditions of job site, and these adopt the hermetically-sealed construction of different materials sealing ring all will fall in the protection domain of the present utility model.
Claims (3)
1. the joint seal structure of a building prefabrication structure "assembling steel bundle pipelin, comprise building prefabrication structure (1) and building prefabrication structure (2), be respectively equipped with in described building prefabrication structure (1) and the described building prefabrication structure (2) and be used to wear the reservation pipeline (5) that draws prestressed strand and reserve pipeline (6), relative the fitting together of opening of the opening of described reservation pipeline (5) and described reservation pipeline (6), it is characterized in that the opening part of fitting relatively at described reservation pipeline (5) and described reservation pipeline (6) is respectively arranged with two sealing ring (3) and sealing rings (4) with different degree of flexibility.
2. the joint seal structure of a kind of building prefabrication structure "assembling steel bundle pipelin as claimed in claim 1, it is characterized in that described sealing ring (3) and described sealing ring (4) are to paste the opening part that is arranged on described reservation pipeline (5) and described reservation pipeline (6) respectively.
3. the joint seal structure of a kind of building prefabrication structure "assembling steel bundle pipelin as claimed in claim 1 is characterized in that, described sealing ring (3) and described sealing ring (4) are made by rubber and foamed plastics respectively.
