Description
Technical field
The utility model belongs to building material technical field, especially relates to the prefabricated inflated rubber core of a kind of highway bridge Hollow screws.
Background technology
In existing highway bridge construction, pre-cast hollow slab is the main upper structural shape of small bridge, and in practice of construction, pre-cast hollow slab area of section is less, people is difficult to enter core inside and carries out template assemblies, formwork and form removal, inflated rubber core Yin Qizhi tears open conveniently, and construction technology is simply widely used in the precast plate girder core of highway small bridge.And in the middle of the construction of inflated rubber core as bridge prefabrication plate, because its volume is very light, because its air has flowing and plasticity, be difficult to fix, usually need a large amount of spacer bars to fix, very uneconomical.Even if like this, also frequent because of in cast concrete process, the very large buoyancy of generation makes inflating rubber core float, and causes precast plate girder top plate thickness not enough, even causes quality accidents.
In order to improve prior art, people have carried out long-term exploration, propose various solution.Such as, Chinese patent literature discloses a kind of precast plate girder inflated rubber core [application number: CN201220247328.X], described inflated rubber core comprises an outer and internal layer, between described outer field inner surface and the outer surface of described internal layer, sandwiched forms a plenum space, the inner surfaces enclose of described internal layer forms a filler space, one end of described plenum space forms a charging valve, the other end of described plenum space forms a venting valve, the two ends in described filler space are closed respectively by a steel flange, one solid-section is formed on the bottom of described plenum space.
Although such scheme to some extent solves the deficiencies in the prior art, difficulty or ease find out gas leakage point, and global design is reasonable not enough.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, the prefabricated inflated rubber core of structure simple highway bridge Hollow screws.
For achieving the above object, the utility model have employed following technical proposal: the prefabricated inflated rubber core of this highway bridge Hollow screws, comprise oval air bag, described oval gasbag ektexine is provided with six around the equally distributed ballonet of oval air bag, described ballonet wrap up by overcoat, it is characterized in that, be connected by flexibly connecting cloth between described ballonet, inflatable chamber is formed between the described outer surface flexibly connecting cloth and oval air bag, be provided with in described inflatable chamber even partition can be become some points of cavitys every cloth, described has the passage that can be communicated with adjacent point of cavity on cloth, described oval air bag is provided with the first inflation inlet be connected with inflatable chamber, described ballonet is provided with the second inflation inlet be connected with inflatable chamber, described flexibly connecting on cloth has air inlet, described flexibly connecting between cloth and overcoat is provided with cotton layer.Inflate just can to inflatable chamber, oval air bag and ballonet by an air inlet; easy to use; flexibly connect cloth and be beneficial to the support force improving this inflated rubber core; avoid sinking between ballonet, cotton layer has protective effect to flexibly connecting cloth, is beneficial to simultaneously and checks gas leakage point; namely when leaking air; fluctuating by cotton layer judges the point that leaks gas, and simple to operate, global design is comparatively reasonable.
In the above-mentioned prefabricated inflated rubber core of highway bridge Hollow screws, described comprises the first partition cloth and the second partition cloth every cloth, the first described partition cloth is all connected with the middle part flexibly connecting cloth with the upper end of the second partition cloth, the other end of the first described partition cloth is connected with the side of oval air bag, and the second described partition cloth is connected with the opposite side of oval air bag.This kind of setting of the first partition cloth and the second partition cloth is beneficial to the support force improving and flexibly connect cloth, avoids excessive convergence.
In the above-mentioned prefabricated inflated rubber core of highway bridge Hollow screws, the other end of the first described partition cloth is also connected with the ballonet of the side being positioned at oval air bag, and the other end of the second described partition cloth is also connected with the ballonet of the opposite side being positioned at oval air bag.This kind of setting of the first partition cloth and the second partition cloth is beneficial to the support force improving and flexibly connect cloth, avoids excessive convergence.
In the above-mentioned prefabricated inflated rubber core of highway bridge Hollow screws, described cotton layer is covered in and flexibly connects cloth outer surface and the surface of cotton layer be stained with the floccule be easy to by blowing afloat.Floccule is beneficial to and checks gas leakage point.
Compared with prior art; the advantage of the prefabricated inflated rubber core of this highway bridge Hollow screws is: one; inflate just can to inflatable chamber, oval air bag and ballonet by an air inlet; easy to use; flexibly connect cloth and be beneficial to the support force improving this inflated rubber core; avoid sinking between ballonet; cotton layer has protective effect to flexibly connecting cloth; be beneficial to simultaneously and check gas leakage point; namely when leaking air; fluctuating by cotton layer judges the point that leaks gas, and simple to operate, global design is comparatively reasonable.This kind of setting of its two, first partition cloth and the second partition cloth is beneficial to the support force improving and flexibly connect cloth, avoids excessive convergence.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides.
In figure, oval air bag 1, ballonet 2, overcoat 3, flexibly connect cloth 4, point cavity 5, cotton layer 6, first partition cloth 7, second partition cloth 8.
Detailed description of the invention
As shown in Figure 1, the prefabricated inflated rubber core of this highway bridge Hollow screws comprises oval air bag 1, oval air bag 1 outer wall is provided with six around the equally distributed ballonet 2 of oval air bag 1, ballonet 2 wrap up by overcoat 3, it is characterized in that, be connected by flexibly connecting cloth 4 between ballonet 2, inflatable chamber is formed between the outer surface flexibly connecting cloth 4 and oval air bag 1, be provided with in inflatable chamber even partition can be become some points of cavitys 5 every cloth, the passage that can be communicated with adjacent point of cavity 5 is had on cloth, oval air bag 1 is provided with the first inflation inlet be connected with inflatable chamber, ballonet 2 is provided with the second inflation inlet be connected with inflatable chamber, flexibly connect on cloth 4 and have air inlet, flexibly connect between cloth 4 and overcoat 3 and be provided with cotton layer 6.Inflate just can to inflatable chamber, oval air bag 1 and ballonet 2 by an air inlet; easy to use; flexibly connect cloth 4 and be beneficial to the support force improving this inflated rubber core; avoid sinking between ballonet 2, cotton layer 6 has protective effect to flexibly connecting cloth 4, is beneficial to simultaneously and checks gas leakage point; namely when leaking air; fluctuating by cotton layer 6 judges the point that leaks gas, and simple to operate, global design is comparatively reasonable.
