Abstract

The utility model relates to a kind of string girder tensioning frock, this string girder tensioning frock comprises: bracing frame, be arranged at two jack on support frame as described above, described two jack are connected with by reinforcing bar the end reinforced mantle fiber being fixedly connected with for the stretching end steel plate with a string beam respectively.The beneficial effects of the utility model are: by two jack that are fixed in gripper shoe, can by opening string beam, stretch very easily, improve the stretching construction of a string beam pretightning force.

Description

A kind of string girder tensioning frock
Technical field
The utility model relates to the technical field of building trade, refers more particularly to a kind of string girder tensioning frock.
Background technology
In building trade, open string beam and need when mounted have certain pretightning force, conventional prestressed stretch-draw adopts jack to stretch, but due to of the prior art string beam fixing jack when the stretch-draw, causes and can not utilize jack to carry out direct stretching construction.
Utility model content
The purpose of this utility model is to provide a kind of string girder tensioning frock, to solve the above-mentioned deficiency of prior art.
The purpose of this utility model is to be achieved through the following technical solutions:
The utility model provides a kind of string girder tensioning frock, this string girder tensioning frock comprises: bracing frame, be arranged at two jack on support frame as described above, described two jack are connected with by reinforcing bar the end reinforced mantle fiber being fixedly connected with for the stretching end steel plate with a string beam respectively.
Preferably, described reinforcing bar is the reinforcing bar of diameter 32mm.
Preferably, described end reinforced mantle fiber is fixedly connected with the stretching end steel plate of a string beam by least two bolts.
Preferably, described reinforcing bar slidable fit is in support frame as described above.
The beneficial effects of the utility model are: by two jack that are fixed in gripper shoe, can by opening string beam, stretch very easily, improve the stretching construction of a string beam pretightning force.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the use state reference map of the string girder tensioning frock described in the utility model embodiment.
In figure:
1, jack; 2, bracing frame; 3, steel cable rope head; 4, end reinforced mantle fiber; 5, stretching end steel plate; 6, reinforcing bar.
The specific embodiment
As shown in Figure 1, a kind of string girder tensioning frock described in the utility model embodiment, this string girder tensioning frock comprises: bracing frame 2, be arranged at two jack 1 on support frame as described above 2, described two jack 1 are connected with by reinforcing bar 6 the end reinforced mantle fiber 4 being fixedly connected with for the stretching end steel plate 5 with a string beam respectively.
Concrete, described reinforcing bar 6 is the reinforcing bar 6 of diameter 32mm, and end reinforced mantle fiber 4 is wherein fixedly connected with the stretching end steel plate 5 of a string beam by least two bolts, and described reinforcing bar 6 slidable fit are in support frame as described above 2.
When work, bracing frame 2 is fixed, meanwhile, unclamp jack 1, make end reinforced mantle fiber 4 be positioned at the outside of stretching end steel plate 5, and make end reinforced mantle fiber 4 fixing with stretching end steel plate 5 by bolt.After fixing, jack 1 is started working, by reinforcing bar 6, pull end reinforced mantle fiber 4 motions, realize the stretching of stretching end steel plate 5, when stretching end steel plate 5 arrives desired position, the fixing steel cable rope head 6 being fixedly connected with stretching end steel plate 5, thus make stretching end steel plate 5 remain on the position of stretching.
By foregoing description, can find out, by two jack 1 that are fixed in gripper shoe, can by opening string beam, stretch very easily, improve the stretching construction of a string beam pretightning force.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
