Abstract
The utility model discloses an embedded thread fastener positioning sleeve pipe; the sleeve pipe is in a shape of a cylinder with an opening at the top end; a ring-shaped lug boss disposed in the axial direction is formed at the periphery of the sleeve pipe; internal threads matched with a fastener are formed in a central hole of the sleeve pipe; a fixed point is arranged at the bottom end of the sleeve pipe; and fixed points are arranged at the periphery of the top end of the sleeve pipe and at the periphery of the bottom end of the sleeve pipe. The utility model has the advantages that the installation is simple and convenient; when the sleeve pipe is pre-embedded into a concrete component, the fixed point at the bottom end of the sleeve pipe is bolted with the steel reinforcement to fix the axial position of the sleeve pipe, thereby preventing the top end of the sleeve pipe from being exposed outside the wall body due to axial moving of the sleeve pipe, particularly, when the sleeve pipe is pre-embedded into the wall body on the top surface, the top end of the sleeve pipe is prevented from sagging outside the wall surface under the self-gravity action of the sleeve pipe, so that the fixation and installation of various devices are convenient.
Description
Technical field
The utility model relates to the locating sleeve of threaded fastener, particularly a kind of locating sleeve that can be embedded in the concrete component.
Background technology
Locating sleeve can be used on the relevant work items of concrete widely, as railway, highway, bridge and house etc., has very high mechanical strength and pulling force.Owing to be provided with long thread segment in the sleeve pipe, prevent that bolt is drawn out thereby can produce very big resistance to the bolt that is spirally connected with it.Chinese patent ZL200620007706.1 has proposed a kind of pre-buried type threaded fastener locating sleeve, the main body of this sleeve pipe is the cylindrical shape that there is opening on the top, described casing main body periphery is connected with a plurality of annular boss, described annular boss axially-aligned, the centre bore of described casing main body has the internal thread that cooperates with securing member, and the top periphery of described casing main body is embedded with a quoit., this locating sleeve pulled out by bolt though thereby can preventing locating sleeve to the bigger resistance of bolt generation that is spirally connected with it; but it is comparatively difficult to the accurate location of this locating sleeve in concrete; because concrete can produce certain pressure in process of setting; make the position of sleeve pipe that skew or rotation take place through regular meeting; especially when sleeve pipe is embedded in the end face body of wall; because the action of gravity of sleeve pipe self; regular meeting hangs down to beyond the metope top of sleeve pipe, thereby to the pre-buried certain difficulty that causes in the location of sleeve pipe.
The utility model content
The purpose of this utility model is to overcome the defective that axial location can't be fixed when locating sleeve was embedded in the concrete component in the prior art, thereby provides a kind of sleeve pipe that can accurately fix its axial location to avoid the top of sleeve pipe to be exposed to outside the body of wall.
The utility model is achieved by the following technical programs.
A kind of pre-buried type threaded fastener locating sleeve, described sleeve pipe is the cylindrical shape that there is opening on the top, and the periphery of described sleeve pipe is provided with the annular boss of arranging vertically, and the centre bore of described sleeve pipe is provided with the internal thread that matches with securing member, wherein, the bottom of described sleeve pipe is provided with fixed point.
Above-mentioned a kind of pre-buried type threaded fastener locating sleeve, wherein, periphery, bottom peripheral and sleeve pipe, the top of described sleeve pipe is provided with fixed point.
Above-mentioned a kind of pre-buried type threaded fastener locating sleeve, wherein, the fixed point of the periphery, bottom of periphery, the top of described sleeve pipe and sleeve pipe respectively is 2 pairs, the angle between the described fixed point becomes 90 degree.
Above-mentioned a kind of pre-buried type threaded fastener locating sleeve, wherein, described fixed point can be button-shape member or the middle semi-circular member that is provided with the hole.
The utility model simple installation, when in the concrete component that sleeve pipe is nuzzled in advance, with the fixed point of casing shoe and reinforcing bar mutually bolt can fix the axial location of sleeve pipe, thereby prevent that sleeve pipe from be exposed to outside the metope its top because of moving axially, especially when sleeve pipe is embedded in the end face body of wall in advance, can prevent that the action of gravity owing to sleeve pipe self from making the top of sleeve pipe hang down to beyond the metope, thereby the fixed installation of various device is brought inconvenience; The fixed point of peripheral and periphery, bottom, the top of sleeve pipe and reinforcing bar can guarantee that sleeve pipe and metope are perpendicular after with the galvanized wire bolt.Owing to each fixed point on the sleeve pipe is fixed on the reinforcing bar with the galvanized wire bolt, thereby pipe box is constituted certain pulling force, can increase the resistance that sleeve pipe is pulled out from concrete by bolt.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of pre-buried type threaded fastener of the utility model locating sleeve, described sleeve pipe 1 has the cylindrical shape of opening for the top, the periphery of described sleeve pipe 1 is provided with the annular boss of arranging vertically 2, the centre bore of described sleeve pipe 1 is provided with the internal thread that matches with securing member, the bottom of described sleeve pipe 1 is provided with fixed point 3, periphery, bottom peripheral and sleeve pipe 1, the top of described sleeve pipe 1 also is provided with fixed point 3, the top of described sleeve pipe 1 the fixed point 3 peripheral and periphery, bottom respectively is 2 pairs, and the angle between described each fixed point 3 becomes 90 degree.Described fixed point 3 can be button-shape member or the middle semi-circular member that is provided with the hole.When in the concrete component of body of wall that sleeve pipe 1 is nuzzled in advance, on each fixed point 3 of at first that galvanized wire 4 bolts are peripheral on the top of sleeve pipe 1 and periphery, bottom, the position of adjusting sleeve pipe 1 makes itself and metope perpendicular, and then the galvanized wire 4 on each fixed point 3 of the top of sleeve pipe 1 is peripheral and periphery, bottom and reinforcing bar 5 bolt mutually, the position of adjusting sleeve pipe 1 again makes its top and metope tangent, thereby last reusable lead silk 4 with the fixed point 3 of sleeve pipe 1 bottom and reinforcing bar 5 mutually bolt the axial location of sleeve pipe 1 is fixed, thereby avoided the top of sleeve pipe 1 to be exposed to outside the metope, and the fixed installation of various device has been brought inconvenience.In order to prevent that sealing and foreign material enter the centre bore inside of sleeve pipe 1, can be provided with serum cap 6 on the top of sleeve pipe 1.During erection equipment, take off serum cap 6, inserting bolt and tightening gets final product.Described sleeve pipe 1 can adopt the high-strength nylon material, makes its insulating properties with height, thereby prevents to corrode underground pipeline and hardware because of the conduction of weak current.
Here description of the present utility model and application are illustrative; be not to want in the above-described embodiments with scope restriction of the present utility model; therefore, the utility model is not subjected to the restriction of present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the scope of the utility model protection.
