Abstract
The utility model discloses a pre-embedded casing. The pre-embedded casing comprises a casing body, wherein bosses are fixedly arranged at the periphery of the casing body. The pre-embedded casing is simple and convenient to mount, when the casing is pre-embedded into a concrete component, the bosses at the periphery of the bottom of the casing prop against concrete to realize a barbing function, so that the casing can be prevented from sliding out of the concrete and the connection of the casing is firm; and moreover, because the bosses are provided with through holes, the bosses can be in pin connection with steel bars so as to fix the casing, and the resistance of pulling the casing out of the concrete is increased.
Description
Technical field
The utility model relates to a kind of sleeve pipe, and particularly a kind of sleeve pipe that is embedded in the concrete belongs to the technical field of connector.
Background technology
Along with the development of society, the use of service sleeve more and more widely.Because service sleeve has intensity and easy to connect preferably, and is widely used on the relevant project of concrete, like railway, highway, bridge and house etc.Traditional service sleeve comprises being provided with the axial thread hole in sleeve body, the sleeve body that the sleeve body periphery is provided with annular boss, the annular boss axially-aligned; During use, sleeve body is embedded in the concrete, is connected with bolt through screwed hole again; The service sleeve of this structure is easy to use, but the location of sleeve pipe in concrete is inconvenient, and being connected in sleeve pipe and the concrete is insecure.
Recently, the Chinese patent document discloses a kind of service sleeve, publication number " CN201574338U "; Patent name is " a kind of pre-buried type threaded fastener locating sleeve "; The periphery that comprises sleeve body, sleeve body bottom and bottom, top is provided with button, is used for being connected with the steelframe of concrete, and sleeve pipe can be located easily; But the sleeve pipe of this structure is relatively poor with the concrete fastness that is connected, and skids off concrete easily.
The utility model content
The utility model technical problem to be solved provides a kind of being connected firmly, and is not easy to skid off concrete and service sleeve simple in structure.
In order to solve the problems of the technologies described above, a kind of service sleeve of the utility model comprises sleeve body, and wherein, said sleeve body periphery is fixedly established boss.
Above-mentioned a kind of service sleeve, wherein, said boss is a back taper.
Above-mentioned a kind of service sleeve, wherein, said boss is provided with perforation.
Above-mentioned a kind of service sleeve, wherein, the periphery of said sleeve body top and bottom is respectively equipped with horizontal projection, and said horizontal projection and said boss are staggered.
Above-mentioned a kind of service sleeve, wherein, said horizontal projection is provided with perforation.
The utility model simple installation, when sleeve pipe is pre-buried when advancing in the concrete component, the boss of periphery is against on the concrete at the bottom of the sleeve pipe, plays the effect of hangnail, can avoid sleeve pipe to skid off concrete, makes the connection of sleeve pipe more firm; In addition because boss is provided with perforation, can with reinforcing bar mutually bolt sleeve pipe is fixed, increased the resistance that sleeve pipe is pulled out from concrete; And the periphery of sleeve body top and bottom is provided with horizontal projection, and horizontal projection and boss are staggered, and it is more firm that sleeve pipe is connected in concrete; And horizontal projection is provided with perforation, during use, can be connected on the concrete reinforcement through wire, can make sleeve pipe guarantee vertical with metope.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in the figure, in order to solve the problems of the technologies described above, a kind of service sleeve of the utility model comprises sleeve body 1, and the sleeve body periphery is provided with annular boss 2, annular boss 2 axially-aligned; Be provided with axial hole in the sleeve body 1, establish screw thread on the hole wall of axial hole, be used for cooperating with bolt; Sleeve body 1 periphery is fixed with boss 3, and boss 3 can be arranged on sleeve body 1 two ends, also can be located at the middle part, and the position is unrestricted, and boss 3 can form resistance in concrete, prevent the sleeve pipe slippage, and it is more firm that sleeve pipe is connected, and uses safer.The shape of boss is unrestricted, can be squarely, also can be other shapes, and in the present embodiment, preferred boss is a back taper, because boss is a back taper, not only can increases the resistance of sleeve pipe, and make the easier for installation of sleeve pipe.More accurate for the location that makes sleeve pipe, connect more firmly, can on said boss 3, be provided with perforation, perforation is used for the bolt steel bars in concrete, and it is more firm that sleeve pipe is connected, and avoids producing displacement.
Further perfect as the present technique scheme can be done following improvement;
Can be respectively equipped with horizontal projection 5 in the periphery of sleeve body 1 top and bottom, said horizontal projection 5 and said boss 3 are staggered, can become the staggered of 90 degree angles; Also can become 60 degree; Or other angles is staggered, makes sleeve pipe laterally and vertically all form resistance, makes the connection of sleeve pipe more firm; In order further to improve the accurate positioning property of sleeve pipe, can on horizontal projection 5, be provided with perforation.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the object of the invention; And be not with opposing qualification of the present invention; As long as in essential scope of the present invention, all will drop in the scope of claim of the present invention variation, the modification of the above embodiment.
Claims (3)
1. a service sleeve comprises sleeve body, it is characterized in that, said sleeve body periphery is fixedly established boss.
2. a kind of according to claim 1 service sleeve is characterized in that said boss is a back taper.
