Abstract
The utility model is related to architectural engineering water-tight devices, are specially a kind of concrete exterior wall bolt hole water-tight device, there is easily infiltration after solving the problems, such as the closure of existing concrete exterior wall bolt hole.Concrete exterior wall bolt hole water-tight device, including the watertight conduit being arranged on the inside of bolt hole, and the inner end of watertight conduit is located at the outside of bolt hole inner end, several inwardly protruded annular grooves are provided on the lateral wall of watertight conduit, the rubber O-ring seal with bolt hole interference fit is cased in annular groove.It is reliable that the structure design of the utility model is reasonable, while bolt hole closure operation is not influenced, is effectively improved waterproof effect, has thoroughly prevented the generation that infiltration gets in phenomenon, had the advantages that simple in structure, easy to process and at low cost.
Description
Technical field
The utility model is related to architectural engineering water-tight devices, are specially a kind of concrete exterior wall bolt hole water-tight device.
Background technology
In building engineering construction, to ensure template strength and rigidity during concrete outer wall template installs, prevent from pouring
The generation for the quality accidents such as mould, spillage, template deformation that occur rising in Concrete is built, is necessary using split bolt reinforcing
Means and measure, so as to which concrete exterior wall split bolt position be caused to generate artificial bolt hole.
After being blocked to concrete exterior wall bolt hole, due to forming gap, exterior wall between the contraction of plugging material and bolt hole wall
Infiltration can penetrate into indoor along bolt hole wall.
The content of the invention
The utility model provides one to solve the problems, such as that existing concrete exterior wall bolt hole has easily infiltration after blocking
Kind concrete exterior wall bolt hole water-tight device.
The utility model adopts the following technical scheme that realization：Concrete exterior wall bolt hole water-tight device, including setting
Watertight conduit on the inside of bolt hole, and the inner end of watertight conduit is located at the outside of bolt hole inner end, the lateral wall of watertight conduit
On be provided with several inwardly protruded annular grooves, be cased in annular groove with bolt hole interference fit rubber O-ring seal.
When carrying out closure operation, closure pipe is built in through watertight conduit on the outside of bolt hole, and ecto-entad is blocked, and is sealed
After the completion of stifled, after external wall seepage penetrates into bolt hole, penetrating passage, while watertight conduit are blocked under the action of rubber O-ring seal
The bulge-structure of madial wall places infiltration through penetrating into interior on the inside of watertight conduit, overcomes the closure of existing concrete exterior wall bolt hole
There are problems that easily infiltration afterwards.
The ring-shaped baffle with bolt hole minor diameter fit is both provided on the inside and outside end wall of watertight conduit.
By the way that ring-shaped baffle is set to separate plugging material with rubber O-ring seal, the same of infiltration effect is further improved
When, extend the service life of rubber O-ring seal.
It is reliable that the structure design of the utility model is reasonable, while bolt hole closure operation is not influenced, is effectively improved
Waterproof effect has thoroughly prevented infiltration and has got in the generation of phenomenon, has simple in structure, easy to process and at low cost excellent
Point.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：1- bolts hole, 2- watertight conduits, 3- annular grooves, 4- rubber O-ring seals, 5- ring-shaped baffles.
Specific embodiment
Concrete exterior wall bolt hole water-tight device, the watertight conduit 2 including being arranged on 1 inside of bolt hole, and watertight conduit 2
