Abstract
The utility model discloses a burying structure with a bolt in a concrete component, which comprises the concrete component and the bolt. One end of the bolt is exposed from the concrete component; a casing pipe is fixedly installed inside the concrete component; inner threads are arranged on the inner wall of the casing pipe; and the other end of the bolt is inserted into the casing pipe and in thread fit with the casing pipe. By means of matching the bolt with the threaded casing pipe, the exposed length of the bolt can be adjusted. The burying structure can be applied to the occasions of steel rail bases and the like possibly having settlement; as the length of the bolt can be adjusted, the bolt needs not to be embedded again when settlement is compensated; and the burying structure greatly improves convenience for construction, and is simple in use and convenient in installation and maintenance.
Description
Technical field
The utility model relates to a kind of structure of burying underground of bolt, particularly a kind of structure of burying bolt in concrete component underground.
Background technology
The pre-embedded bolt that uses in the prior art all is directly bolt to be embedded in the concrete component, perhaps the mode by chemical anchoring with bolt anchoring in concrete component, in case after burying underground, the exposed length of bolt just can't have been regulated.
At present, many port workss are all built on the deep soft foundation, adopt bucket wheel machine or carloader to carry out production operation as needing in the port works bulk storage yard.Adopt sleeper ballast aggregate structure during bucket wheel machine basis or carloader basis general design, and anchor ingot basis, jacking basis, car bumper basis because to bear bigger horizontal force, to upper pulling force or vertical force, generally adopt bigger single footing.Because the silt depth that the basis exists down is inhomogeneous, the ground treatment effect is inconsistent, soft or hard junction and single footing and sleeper basis subsidiary stress are different, thereby cause sleeper basis and single footing to exist sedimentation inconsistent, the sleeper basis can reset sleeper by filling out ballast aggregate, and the single footing is because deadweight is excessive, be difficult to its lifting or raise, thereby it is discontinuous to make that rail occurs herein.
In order to make rail between single footing and the sleeper along connecing, way commonly used is the top of single footing to be carried out cast-in-place, and then, on the basis of newly building, expandable implant bolt or reinforcing bar are last again, again fastener for installing or built-in fitting.This method can only solve disposable settlement issues, if but sedimentation is continued on the basis, and then need once more expandable implant bolt or reinforcing bar again, and may need for the third time even the 4th bar planting, thereby increase construction investment, influence normal production operation.In addition,, once more when expandable implant bolt or reinforcing bar, can exist with the expansion bolt of original implantation or reinforcing bar and conflict, also have certain problem in the construction because the relative position of built-in fitting fixes.
The utility model content
The technical problems to be solved in the utility model provides the adjustable bolt of a kind of exposed length and buries structure underground, to overcome the above-mentioned defective of prior art.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bolt is buried structure underground in concrete component, comprise concrete component and bolt, one end of bolt exposes from concrete component, be installed with sleeve pipe in the described concrete component, the inwall of sleeve pipe is provided with internal thread, and the other end of described bolt is inserted in the sleeve pipe and with casing threads and cooperates.
Preferably, described concrete component is a concrete foundation.
Preferably, described sleeve pipe is embedded in the concrete component, and the outer wall of sleeve pipe is provided with outstanding floor.
Preferably, described sleeve pipe chemical anchoring is in concrete component.
The beneficial effects of the utility model are, are provided with threaded sleeve in concrete component, by cooperating of bolt and threaded sleeve, the exposed length of bolt can be regulated.Can be applied in the occasions such as rail basis that sedimentation can take place,, improve the convenience of construction greatly because the adjustable length of bolt when sedimentation is compensated, can be implanted bolt again.The utility model uses simply, installation and maintenance are convenient.
Description of drawings
Fig. 1 is that the utility model bolt is buried structural representation underground in concrete component.
Fig. 2 is the schematic diagram when highly compensating.
The specific embodiment
As shown in Figure 1, be installed with sleeve pipe 3 in concrete component 1, the inwall of sleeve pipe 3 is provided with internal thread, and bolt 2 is that an overall length all has externally threaded screw rod, one end of screw rod be inserted in the sleeve pipe 3 and with sleeve pipe 3 threaded engagement, the other end of screw rod exposes from concrete component 1.Like this, bolt 2 just can spinning in and out freely in sleeve pipe 3, thereby the length that makes bolt 2 expose concrete foundation 1 can be regulated.
Bolt and sleeve pipe adopt Q235 steel or other to satisfy the material of function of use, need relative settlement amount and resistance to plucking or tension technical requirements according to the basis in design, determine the length of sleeve pipe and bolt.
Obviously, the utility model is not limited to the installation of rail, by bolt various device is installed on concrete component, if in use need the setting height(from bottom) of equipment is adjusted, can adopt structure of the present utility model.Therefore, the utility model can use in fields such as harbour, railway and building.
