Abstract
The utility model provides a prestress steel strand rack beam which comprises a rack beam body, an elastic body and a beam body. The rack beam body comprises a base and a beam frame, one end of the elastic body is fixed to the base, and the other end of the elastic body is fixed to the beam frame. The beam body is provided with wire penetrating holes, and the beam body is fixed to the rack beam body. The prestress steel strand rack beam has the advantages that it is ensured that a steel strand can be stably stretched in the stretching process, buffering adjustment is achieved through the design of the elastic body on the rack beam body, the stress of a product is further ensured, and the quality of the product is ensured.
Description
Technical field
The invention belongs to building prefabricated components field, especially relates to a kind of prestress wire body of setting a roof beam in place.
Background technology
At present in actual production because of the arrangement stable mechanical property of fish belly sill, rigidity is large etc., and advantage is widely used.But the fixing stability of fish belly sill is unsatisfactory, when Method of Steel Strand Stretching, is difficult to guarantee stable pulling, affects product stress.
Summary of the invention
The problem that the invention will solve is a kind of prestress wire of proof stress steel strand wires stable pulling body of setting a roof beam in place.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of prestress wire body of setting a roof beam in place, comprises the body of setting a roof beam in place, elastomer and beam body; The described body of setting a roof beam in place comprises base and roof beam structure, and described elastomeric one end is fixed on base, and the other end is fixed on roof beam structure; Described beam body is provided with through wires hole and described beam body and is fixed on and sets a roof beam in place on body.
Preferably, described roof beam structure is inverted trapezoidal and trapezoidal upper bottom opening.
Preferably, base and the roof beam structure of body of setting a roof beam in place described in is one-body molded.
Preferably, described beam body is trapezoidal.
Preferably, described elastomer is provided with at least two and symmetrical.
Preferably, the through wires hole that described beam body is provided with is at least provided with 3.
Advantage and good effect that the invention has are: guarantee that steel strand wires can stable pulling in drawing process, the elastomer design of simultaneously setting a roof beam in place on body realizes slow-readjustment joint, further guarantees product stress, guarantees product quality.
Accompanying drawing explanation
Fig. 1 is the invention structural representation;
In figure: the 1-frame of setting a roof beam in place, 11-base, 12-roof beam structure, 13-elastomer, 2-beam body, 3-through wires hole, 4-prestress wire
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is elaborated.
The prestress wire body of setting a roof beam in place, comprises the body 1 of setting a roof beam in place, elastomer 13 and beam body 2; The described body 1 of setting a roof beam in place comprises base 11 and roof beam structure 12, and one end of described elastomer 13 is fixed on base 11, and the other end is fixed on roof beam structure 12; Described beam body 2 is provided with through wires hole 3 and described beam body 2 and is fixed on and sets a roof beam in place on body 1.Described roof beam structure 12 is inverted trapezoidal and trapezoidal upper bottom opening.Base 11 and the roof beam structure 12 of the described body 1 of setting a roof beam in place are one-body molded.Described beam body 2 is trapezoidal.Described elastomer 13 is provided with at least two and symmetrical.The through wires hole 3 that described beam body 2 is provided with is at least provided with 3.
When actual production, prestress wire 4 is passed to through wires hole 3 and is fixedly connected with by ground tackle, on prestress wire 4, stress application stretches, and finally carries out concreting.
Above the invention embodiment is had been described in detail, but described content is only the preferred embodiment of the invention, can not be considered to for limiting the practical range of the invention.All equalization variations of doing according to the invention application range and improvement etc., within all should still belonging to the patent covering scope of the invention.
