Abstract
The utility model discloses stretching rope constructing devices in a kind of prestressed steel structure, it includes steel strand wires, it further include the fixed plate being fixedly connected on girder steel, through-hole is opened up in the middle part of the fixed plate, cored screw passes through the through-hole and can move along the axis direction of the through-hole, nut and the cored screw threaded engagement in the fixed plate side, the cored screw are clamped intermediate plate close to one end of the nut, and the steel strand wires pass through the cored screw and the intermediate plate.The utility model structure is simple, easy to install and use, is highly suitable for locally applying prestressing force to steel beam structure.
Description
Technical field
The utility model belongs to prestressed steel structure technology field, in particular to stretching rope is applied in a kind of prestressed steel structure
Tooling is set.
Background technique
Prestressed steel structure is exactly to apply pressure to it in advance before structure bearing load, makes it in outer load action
When tensile region internal force generate compression, to offset or reduce external load generation tensile stress, make structure in normal use
In the case of be not deformed or brittle break.Apply prestressed purpose in steel construction except the rigidity of structure is improved, improves structure
Performance.In the prior art, steel construction apply prestressed method first is that tensioning cable method, such mode are in stretching rope
Hydraulic-pressure anchor head is arranged in both ends, but it installs and uses inconvenience, especially when locally applying prestressing force to steel construction, such as to steel
Beam applies prestressing force, and operation installation is more inconvenient.
Utility model content
Stretching rope is applied in a kind of the purpose of this utility model is to provide structures prestressed steel structure simple, easy for installation
Tooling is set.
To achieve the above object, the technical solution of the utility model is as follows:
Stretching rope constructing device in a kind of prestressed steel structure, including steel strand wires, further include being fixedly connected on girder steel
Fixed plate, the fixed plate middle part open up through-hole, and cored screw passes through the through-hole and can be along the axis direction of the through-hole
Mobile, in the fixed plate side nut and the cored screw threaded engagement, the cored screw is close to the nut
One end is clamped intermediate plate, and the steel strand wires pass through the cored screw and the intermediate plate.
The intermediate plate is pyramidal structure, and the narrow end of the intermediate plate protrudes into the cavity of the cored screw, and wide end diameter is big
In the cavity diameter of the cored screw.
The intermediate plate is made of symmetrical two parts, and the intermediate plate is for steel strand wires described in clamping.
Gasket is equipped between the nut and the fixed plate.
Compared with prior art, the technical effect of the utility model are as follows:
1. hollow spiral shell may be implemented by rotary nut in the nut of fixed plate side and the cored screw threaded engagement
The axial movement of bar realizes the stretching of steel strand wires to drive the axial movement of steel strand wires.
2. intermediate plate is pyramidal structure, the narrow end of the intermediate plate is protruded into the cavity of the cored screw, and wide end diameter is greater than
The cavity diameter of the cored screw, steel strand wires pass through the cavity of intermediate plate, it is ensured that intermediate plate prevents the clamped condition of steel strand wires
Only steel strand wires pine is sliding.
3. being equipped with gasket between the nut and the fixed plate, avoids nut from directly contacting fixed plate and cause to wear.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view structural representation of Fig. 1.
Specific embodiment
Stretching rope constructing device in a kind of prestressed steel structure shown in -2 referring to Fig.1, including steel strand wires 1, further include weldering
It connects on girder steel and middle part is provided with the fixed plate 2 of through-hole, cored screw 3 passes through through-hole and can be along the axis direction of the through-hole
Mobile, in 2 left side of fixed plate nut 4 and 1 threaded engagement of cored screw, the left end of the cored screw 1 is clamped
There is pyramidal structure intermediate plate 6, the narrow end of the intermediate plate 6 protrudes into the cavity of the cored screw 3, and wide end diameter is greater than described hollow
The cavity diameter of screw rod 3, the intermediate plate 6 are made of symmetrical two parts, and the intermediate plate 6 is used for steel strand wires 1 described in clamping,
The steel strand wires 1 pass through the cored screw 3 and the intermediate plate 6, and circular pad is equipped between the nut 4 and the fixed plate 2
Piece 5.
In use, two fixed plates are respectively welded needing to apply prestressed girder steel, then divide in every piece of fixed plate
Not Zu Zhuan cored screw, gasket and nut, then the both ends of steel strand wires are each passed through the cored screw at both ends, last installation folder
Piece, then a hand blocks cored screw with clamp, and another hand turns nut with clamp, since nut is withstood on admittedly by gasket
The side of fixed board cannot axially move, and the cored screw will axially move, and the drawing of steel strand wires thus may be implemented
It stretches.
Claims (4)
1. stretching rope constructing device in a kind of prestressed steel structure, including steel strand wires, which is characterized in that it includes being fixedly connected on
Fixed plate on girder steel, the fixed plate middle part open up through-hole, and cored screw passes through the through-hole and can be along the through-hole
