Abstract
The utility model discloses a kind of high ferro prefabricated case beam end-blocking rubber sleeve, comprise the annular rubber ring be sleeved on case beam anchor recess template preformed hole pipe, the external surface of described annular rubber ring is arc-shaped structure, and inner surface is in the bell-mouth structure of air tilted.The utility model has the advantage of that structure is simple, easy to use, remarkably productive.Be sleeved on each preformed hole pipe of anchor recess template before cast and (be fixed in 1/3 place of hole pipe with binding), after cast after concrete setting, case beam-ends mould are removed, with crowbar, the rubber sleeve be retained in case beam end anchor recess is pried open, easily shut down and can again continue to use.Now, owing to forming an annular groove on shaping anchor recess inside wall, only need by anchor recess wall dabbing during construction, pour into a mould and can embed in the annular groove of anchor recess after the end-blocking concrete setting of anchor recess, ensure that end-blocking quality, effectively improve the globality between case beam end sealing off and covering anchorage concrete and case beam.
Description
Technical field
The utility model relates to high ferro prefabricated case beam, especially relates to a kind of high ferro prefabricated case beam end-blocking rubber sleeve.
Background technology
Along with the develop rapidly of railway construction in China, high ferro engineering design and construction technical level is improving constantly, Bridge Types is also more complicated various, prefabricated case beam is slim and graceful with its structure, building height is little, arrangement of reinforcement is few, compare the advantages such as construction of cast-in-situ box-beam speed is quick, generally uses in high-speed rail bridge.Simultaneously, along with the quickening of China Express Railway and PDL Construction speed and scale expand gradually, to introducing new technology in work progress, the demand of new technology also increases day by day, make great efforts to seek the technical measures that various reduction consumes, the new technology, new technology, new material etc. of raising work efficiency reduce costs, amplification input and output price scissors, accelerating construction progress become each construction enterprises' urgent problem.Be adopt anchor recess concrete dabbing technology during the anchor recess end-blocking of existing prefabricated case beam prestressing force end, namely after dismounting end mould, first by the inner side dabbing of anchor recess, and then pour into a mould sealing off and covering anchorage concrete.
Prefabricated case beam through the method process is erected at after on high ferro railway, because operating vibration very easily causes anchor recess sealing off and covering anchorage concrete to ftracture in case beam end, serious even can drop out, and sealing off and covering anchorage concrete is once cracking, namely steam can enter case beam internal corrosion reinforcing bar from cracking, cannot ensure the service life of high ferro prefabricated case beam.
Summary of the invention
The purpose of this utility model is to provide a kind of high ferro prefabricated case beam end-blocking rubber sleeve, effectively can improve the globality between case beam end sealing off and covering anchorage concrete and case beam.
For achieving the above object, the utility model can take following technical proposals:
High ferro prefabricated case beam end-blocking rubber sleeve described in the utility model, comprise the annular rubber ring be sleeved on case beam anchor recess template preformed hole pipe, the external surface of described annular rubber ring is arc-shaped structure, and inner surface is in the bell-mouth structure of air tilted.
Preformed hole pipe due to case beam-ends mould avris is the arrangement of single order, and annular rubber ring used is cirque structure.
Because the preformed hole pipe in the middle part of case beam-ends mould is the arrangement of triplets order, annular rubber ring used is the long loop configuration that three circles are horizontally connected.
According to the designing requirement of case beam end, the gradient of prestress pipe is different, so the inner surface gradient of annular rubber ring can adjust between 2 ° ~ 6.5 °.
The utility model has the advantage of that structure is simple, easy to use, remarkably productive.Be sleeved on each preformed hole pipe of anchor recess template before cast and (be fixed in 1/3 place of hole pipe with binding), after cast after concrete setting, case beam-ends mould are removed, with crowbar, the rubber sleeve be retained in case beam end anchor recess is pried open, easily shut down and can again continue to use.Now, owing to forming an annular groove on shaping anchor recess inside wall, only need by anchor recess wall dabbing during construction, pour into a mould and can embed in the annular groove of anchor recess after the end-blocking concrete setting of anchor recess, ensure that end-blocking quality, effectively improve the globality between case beam end sealing off and covering anchorage concrete and case beam.

Detailed description of the invention
Embodiment 1
As shown in Figure 1, 2, high ferro prefabricated case beam end-blocking rubber sleeve described in the utility model, comprise the annular rubber circle 2 be sleeved on case beam anchor cavity mold edges of boards side preformed hole pipe 1, the external surface of this annular rubber circle 2 is arc-shaped structure, and inner surface is in the bell-mouth structure of air tilted; According to the gradient of prestress pipe design, the inner surface gradient of annular rubber circle 2 adjusts between 2 ° ~ 6.5 °.
Embodiment 2
As shown in Figure 1,3, high ferro prefabricated case beam end-blocking rubber sleeve described in the utility model, comprises the long loop configuration being sleeved on three circles below case beam anchor recess template on one group of three the preformed hole pipe 1 in middle part and being horizontally connected.
This use Novel complete set uses, as shown in Figure 4, the dual-side rule of case beam anchor recess template 3 be disposed with preformed hole pipe 1, lower horizontal is arranged with ternary preformed hole pipe group, for convenience of the dismounting of cast rear cabinet beam anchor recess template 3, preformed hole pipe is interior thick outer thin conical structure.
Before the anchor recess cast of case beam end, annular rubber circle 2 is sleeved on the preformed hole pipe 1 of case beam anchor recess template 3 both sides, the rubber ring 2 of long loop configuration is sleeved in the preformed hole pipe group of case beam-ends mould 3 bottom and (binding or additive method can be adopted to be fixed in 1/3 place of hole pipe).Case beam anchor recess template 3 is removed by anchor recess casting complete after concrete initial set, now rubber ring 2 can be retained in the anchor recess of case beam end, at this moment adopt crowbar to be pried open, easily shut down, an annular groove will be formed like this on shaping anchor recess inside wall.During cast end-blocking concrete construction, only need by anchor recess wall dabbing, pour into a mould and will embed in the annular groove of anchor recess after the end-blocking concrete setting of anchor recess, even if high ferro is run and is vibrated in the future, also there will not be the phenomenon that sealing off and covering anchorage concrete ftractures in case beam end, drops out, ensure that the end-blocking quality of case beam, effectively improve the globality between case beam end sealing off and covering anchorage concrete and case beam.
During actual manufacture, annular rubber ring 2 can adopt ethylene propylene diene rubber manufacture, make it have good ageing-resistant, ozone resistance, weatherability, heat resistance and chemical resistance, so hardness is high, toughness by force and not yielding, can Reusability 100 ~ 200 times, cost is low and economical and practical, can bundledly stack at ordinary times, transport, preserve all very convenient.
