Abstract
The utility model relates to an anti-loose self anchor connector, which comprises a connecting body and a clamping piece. The anti-loose self anchor connector is characterized in that the connector is at least provided with two taper through roles in adverse direction, the clamping piece is arranged in the taper through roles, an anti-loose pressing plate is arranged on the connector through the adapting piece, a spring is arrange between the anti-loose pressing plate and the clamping piece, the spring is located a major diameter end of the taper through roles, and a hole corresponding to the taper through roles is respectively arranged on the anti-loose pressing plate. The anti-loose self anchor connector has the advantages of being simple in structure, easy to manufacture, and convenient to use.
Description
Technical field
The utility model belongs to the prestressed anchor technical field, particularly relates to a kind of locking from anchor connector.
Background technology
Prestressed anchor is the ground tackle that is applicable to that the concrete pre-stress stretch-draw in the engineering construction process is used.In the prestressed reinforced concrete construction; When the engineering of prestressed concrete is long; Can cause bigger loss of prestress at concrete end stretch-draw steel strand, need to adopt prestress steel twist wiring connector subsection tension prestress wire, to reduce the loss of prestress in the prestressed concrete.
The structure of common steel strand connector is in the prior art: comprise connector, intermediate plate and protective cover; Connector is provided with tapered hole; Intermediate plate is positioned at the tapered hole of connector, and the excircle of connector is provided with wire casing, and an end of one steel strand is locked in the taper hole of connector through intermediate plate; One end of another strand steel strand is installed extrusion head and is clamped on the connector through wire casing, and connector is inserted in the connection that both can realize two strands of steel strand in the protective cover.Above-mentioned connector is complex structure not only, and production and processing is not easy, and the connection process very complicated of steel strand, uses inconvenient.
Summary of the invention
The utility model provides a kind of simple in structure, handling ease, easy to use locking from anchor connector for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of locking from anchor connector; Comprise connector and intermediate plate; It is characterized in that: be provided with the opposite taper through hole of both direction on the said connector at least; Be provided with intermediate plate in the said taper through hole, through connector locking pressing plate be installed on the said connector, between said locking pressing plate and said intermediate plate, spring is set; Said spring is positioned at the bigger diameter end of taper through hole, and said locking pressing plate is provided with and the corresponding hole of taper through hole.
The utility model can also adopt following technical scheme:
Said connector is a bolt.
The advantage that the utlity model has with good effect is: compare with steel strand connector of the prior art, the utility model simple in structure made handling ease.In addition, when steel strand were installed, operating personnel only needed the end miner diameter end of the taper through hole insertion on the connector from this is novel with steel strand, and afterwards steel strand being applied an outside pulling force can be locked at steel strand on the connector, extremely easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of connector in the utility model.
Among the figure: 1, connector; 1-1, taper through hole; 2, steel strand; 3, intermediate plate; 4, locking pressing plate; 5, spring.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2, locking from anchor connector, comprise connector 1, be provided with the opposite taper through hole 1-1 of both direction on the connector 1 at least, make connector to connect two strands of steel strand 2 at least.Be provided with intermediate plate 3 in the taper through hole 1-1 of connector 1; Through connector locking pressing plate 4 is installed on the connector 1; Between locking pressing plate 4 and the intermediate plate 3 spring 5 is set; Spring 5 is positioned at the bigger diameter end of taper through hole 1-1, and promptly locking pressing plate 4 of the two ends of spring 5 difference roof pressure and intermediate plate 3 cause intermediate plate 3 to be pressed and put in the taper through hole 1-1 of connector 1.Locking pressing plate 4 is provided with the corresponding hole with taper through hole 1-1.In the present embodiment, connector 1 is a disc, is uniformly distributed with 3 taper through hole 1-1 at the middle part of connector 1, around above-mentioned 3 taper through holes on connector near its excircle to being uniformly distributed with 33 taper through holes in the opposite direction with above-mentioned taper through hole; Locking pressing plate is installed on the connector through bolt.
Concrete method for using
At first an end of one steel strand is passed the hole of locking pressing plate and insert the miner diameter end of taper through hole on the connector; The top roof pressure of steel strand is positioned at the inner intermediate plate of taper through hole; The intermediate plate extrusion spring also moves to the bigger diameter end of taper through hole, and intermediate plate expands to open until Working-Clip sleeve gradually in the process that the bigger diameter end to the taper through hole moves and is contained on the steel strand, and steel strand are about to steel strand to pulling back after stretching out intermediate plate one segment length; Under the effect on spring and taper through hole inclined-plane; The intermediate plate frictionally is locked at steel strand on the connector, reliably locks in order to make steel strand, must when steel strand are pulled back, apply certain pulling force to steel strand.With the method the steel strand of the connector other end are installed, realized the link of connector two ends steel strand with this.The installation process of above-mentioned steel strand can simplified summary be " one inserts one draws ", operates very simple, and easy to use.
Claims (2)
- One kind locking from anchor connector; Comprise connector and intermediate plate, it is characterized in that: be provided with the opposite taper through hole of both direction on the said connector at least, be provided with intermediate plate in the said taper through hole; Through connector locking pressing plate is installed on the said connector; Between said locking pressing plate and said intermediate plate, spring is set, said spring is positioned at the bigger diameter end of taper through hole, and said locking pressing plate is provided with and the corresponding hole of taper through hole.
- 2. according to claim 1 locking from anchor connector, it is characterized in that: said connector is a bolt.
