Abstract
The utility model relates to a prestressed reinforcement fixed end anchorage, comprising: a connecting screw, a connecting sleeve and a clip anchorage. External thread is arranged on two terminals of the connecting screw. A via hole is arranged in the middle part of the connecting sleeve. Left end of the via hole is provided with left internal thread and right end of the via hole is provided with right internal thread. Rotation directions of the left internal thread and the right internal thread are opposite. The connecting sleeve is bolt jointed with the connecting screw via the left internal thread. The clip anchorage is consisted of an anchor ring provided with a taper hole and two clips arranged in the anchor ring. Two clips are assembled into a cylinder whose outer surface is conical surface. Outer surface of the anchor ring is provided with the external thread which is bolt jointed with the right internal thread of the connecting sleeve. The prestressed reinforcement fixed end anchorage of the utility model can satisfy a requirement that concrete column or wall is constructed precede beam or plate.
Description
Technical field
The utility model relates to a kind of presstressed reinforcing steel fixed end ground tackle.
Background technology
Known construction of prestressed concrete is in proper order: a template, lay plain bars, lay the fixed end ground tackle of presstressed reinforcing steel and presstressed reinforcing steel, the fixed end ground tackle of presstressed reinforcing steel comprises sleeve and backing plate, sleeve adopts fashion of extrusion to be connected with the end of presstressed reinforcing steel, fixedlys connected in the inner end of backing plate and sleeve.The fixed end ground tackle of presstressed reinforcing steel generally is placed on concrete wall or post the inside, so concrete wall or post must be built together with prestressed girder or plate, but because the requirement of construction technology, often require concrete column or wall prior to beam or plate construction earlier, so original prestressing force fixed end ground tackle is not suitable for this sequence of construction.
The utility model content
The purpose of this utility model provides a kind of presstressed reinforcing steel fixed end ground tackle that satisfies concrete column or wall prior to beam or plate construction.
For achieving the above object, the utility model is taked following design scheme:
A kind of presstressed reinforcing steel fixed end ground tackle is characterized in that it comprises: connecting screw rod, branch sleeve and intermediate plate ground tackle;
The two ends of described connecting screw rod are provided with external screw thread;
Described branch sleeve middle part has a through hole, and the left end of described through hole has left internal thread, and the right-hand member of described through hole has right internal thread, and the rotation direction of described left internal thread and right internal thread is opposite; Described branch sleeve is by left internal thread and connecting screw rod bolt;
Described intermediate plate ground tackle is by the anchor ring with taper hole and place two intermediate plates in the described anchor ring to form, and two described intermediate plates are combined into the cylinder that external surface is the conical surface, and described anchor ring external surface has the external screw thread with the right internal thread bolt of described branch sleeve.
The utility model has the advantages that:
The utility model presstressed reinforcing steel fixed end ground tackle is owing to adopt above design scheme, during use, in advance an end anchor of connecting screw rod in concrete wall or post, when spreading presstressed reinforcing steel by the time, presstressed reinforcing steel is fixedlyed connected branch sleeve and connecting screw rod bolt by the intermediate plate ground tackle with branch sleeve.Because branch sleeve and connecting screw rod be connected and branch sleeve was threaded with being connected all of intermediate plate ground tackle, so can satisfy the requirement of concrete column or wall prior to beam or plate construction, very easy to use.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
As shown in Figure 1, a kind of presstressed reinforcing steel fixed end of the utility model ground tackle is characterized in that it comprises: connecting screw rod 1, branch sleeve 2 and intermediate plate ground tackle 3;
The two ends of connecting screw rod 1 are provided with external screw thread;
Intermediate plate ground tackle 3 is by the anchor ring 6 with taper hole and place two intermediate plates 7 in the anchor ring 6 to form, and two intermediate plates 7 are combined into the cylinder that external surface is the conical surface, and anchor ring 6 external surfaces have the external screw thread with branch sleeve 2 right internal thread 5 bolts.
During use, in advance an end anchor of connecting screw rod 1 in concrete wall or post, end in concrete wall or the post has external screw thread so bonding strength is better because connecting screw rod 1 is anchored in, when spreading presstressed reinforcing steel 8 by the time, presstressed reinforcing steel 8 is fixedlyed connected with branch sleeve 2 by intermediate plate ground tackle 3, branch sleeve 2 and connecting screw rod 1 bolt.Because branch sleeve 2 and connecting screw rod 1 be connected and branch sleeve 2 was threaded with being connected all of intermediate plate ground tackle 3, so can satisfy the requirement of concrete column or wall prior to beam or plate construction, very easy to use.
