Description
Technical Field
The utility model relates to a precast beam prestressing force stretch-draw platform.
Background
Along with the development of bridge construction in China, the prestressed precast beam is adapted to the development trend of bridge construction and is rapidly developed, a safe and firm tensioning platform cannot be erected due to the limitation of construction conditions, different tensioning platforms need to be erected at different positions, so that the erecting and dismantling workload is large, the construction period is long, and the requirements of safe and reliable construction, convenience and quickness in construction and high construction speed cannot be met. Meanwhile, due to the limitation of construction space, after the tensioning platform is erected, the danger is often great, and the safety of constructors cannot be guaranteed.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a precast beam prestressing force stretch-draw platform that simple structure, work efficiency are high.
The utility model provides a technical scheme of above-mentioned problem is: the utility model provides a precast beam prestressing force stretch-draw platform, hangs the mechanism including braced frame, jack suspension mechanism includes couple, chain block, horizon bar, jack, the horizon bar sets up on braced frame, and the couple is hung on the horizon bar, and chain block hangs on the couple, the braced frame is improved level and is equipped with construction platform, is equipped with the jack on the construction platform, and the jack is connected with the chain block lower extreme.
Above-mentioned precast beam prestressing force stretch-draw platform, braced frame includes four stands, two horizontal beam, two horizontal longerons, and four vertical settings of stand just are square putting, and two horizontal beam, two horizontal longerons are square putting at four stand tops and constitute a box frame construction jointly with four stands, four angles of construction platform are fixed respectively in four stand lower parts.
The bottom of each of the four stand columns is provided with a roller.
According to the precast beam prestress tensioning platform, the baffle is welded on one side of the supporting frame.
The beneficial effects of the utility model reside in that: the utility model provides a portable, simple structure, convenient operation's precast beam prestressing force stretch-draw platform can remove by arbitrary direction all around, for the construction provides nimble convenient construction position, has simplified the construction greatly, has shortened the time limit for a project. The jack can also move horizontally and vertically, and can move in combination with the tensioning platform, so that the prestress tensioning at any position can be realized. In addition, potential safety hazards are prevented to a certain extent by the arranged baffle, and the safety of constructors is guaranteed to a certain extent.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the precast beam prestress tensioning platform comprises a support frame and a jack suspension mechanism, wherein the jack suspension mechanism comprises a hook 5, a chain block 6, a horizontal rod 4 and a jack 8, the horizontal rod 4 is arranged on the support frame, and the hook 5 is hung on the horizontal rod 4 and can be freely moved; the chain block 6 is hung on the hook 5, the support frame is horizontally provided with a construction platform 10, the construction platform 10 is provided with a jack 8, and the jack 8 is connected with the lower end of the chain block 6. A baffle plate 9 is welded on one side of the supporting frame, so that potential safety hazards can be prevented.
The supporting frame comprises four stand columns 2, two horizontal cross beams 3 and two horizontal longitudinal beams 11, wherein the four stand columns 2 are vertically arranged and are placed in a square mode, rollers 1 are arranged at the bottoms of the four stand columns 2, the two horizontal cross beams 3 and the two horizontal longitudinal beams 11 are placed at the tops of the four stand columns 2 in a square mode and form a box-type frame structure together with the four stand columns 2, the four corners of the construction platform 10 are fixed to the lower portions of the four stand columns 2 respectively, and constructors can operate on the construction platform 10 in a standing mode.
The utility model is simple in operation, convenient to use. Only need with the utility model discloses remove to the assigned position, can remove wantonly on the level land, and control easily. After the steel bar tensioning jack is moved to a specified position, the jack 8 can be lifted at will and adjusted in the horizontal and vertical directions, a constructor fixes the steel bar to be tensioned on a tensioning platform, and then a machine switch is turned on for operation.
