Description

Technical Field

[0001] The present application relates to the technical field of building components, and in particular to a prestressed steel strand bundle braiding platform. Background Art

[0002] In the existing technology, in order to increase the bearing capacity and durability of the cap beam, prestressed steel strands are usually passed through a corrugated tube embedded in the cap beam. Since there are multiple steel strands passed through, anchor plates are provided to fix several steel strands, and the two ends are tensioned to generate the required prestress. Finally, grouting is performed to fix the position of the steel bars to complete the construction.

[0003] Since they are usually passed through the corrugated tube one by one, as the number of steel strands increases, the difficulty of subsequent passing through the corrugated tube increases, which is relatively time-consuming, affecting the threading efficiency and the construction progress, and therefore needs further improvement. Utility Model Content

[0004] In order to reduce the impact on the construction progress of subsequent steel strands passing through corrugated pipes, the present application provides a prestressed steel strand bundle bundling platform.

[0005] This application provides a prestressed steel strand bundle bundling platform, which adopts the following technical solutions:

[0006] A prestressed steel strand bundle braiding platform includes several support frames, support rollers rotatably connected to the support frames, and limit rods arranged on both sides of the support frames. Several support rollers are arranged at intervals along the length direction of the support frames, and several limit rods are arranged at intervals along the length direction of the support frames. The length direction of the limit rods is parallel to the height direction of the support frames.

[0007] By adopting the above technical solution, since the length of the steel strand is relatively long, a number of support frames are provided so that relatively small support frames can be made for transportation to the site. It is also convenient to select a corresponding number of support frames according to the length of the steel strand and arrange them to form a relatively long placement platform, which reduces the wear of the steel strand when it is placed on the ground. It also has a certain height so that the on-site staff can bundle several steel strands on the platform. After bundling, they are lifted by a crane to carry out other subsequent construction work, thereby reducing the difficulty of passing the steel strands one by one through the corrugated tube and the corresponding time spent. Among them, the support roller is provided to pull the steel strand to reduce damage to the outer surface of the steel strand. The limit rod is provided to limit the movement range of the steel strand, and because it has a certain width, it is convenient for arrangement and combing.

[0008] Preferably, the support frame includes two first cross bars arranged in parallel, two second cross bars respectively arranged between the two ends of two adjacent first cross bars, and four vertical bars respectively arranged at the ends of the two first cross bars, the length of the first cross bar is longer than the length of the second cross bar, the two ends of the support roller are respectively rotatably connected to the two first cross bars, and the limit rod is set on the first cross bar.

[0009] By adopting the above technical solution and the above structure, a support frame is assembled, and the overall weight is relatively light and relatively easy to carry.

[0010] Preferably, the support frame further includes two first reinforcing rods respectively parallel to the two first cross rods and two second reinforcing rods respectively parallel to the two second cross rods, and both ends of the first reinforcing rod and the second reinforcing rod are respectively connected to the vertical rod.

[0011] By adopting the above technical solution and providing the first reinforcing rod and the second reinforcing rod, the supporting effect of the overall support frame is improved, thereby improving the support for the steel strands and thereby extending the service life of the support frame.

[0012] Preferably, the length of the first cross bar is more than twice the length of the second cross bar, and two limiting rods are provided on the first cross bar, and the two limiting rods are respectively provided close to the ends of the first cross bar.

[0013] By adopting the above technical solution, the bundling platform is usually used multiple times. Therefore, during transportation, in order to reduce the transportation cost caused by the installation of multiple support frames, the length of the first crossbar is twice or more than the length of the second crossbar, so that the lengths of the two support frames are perpendicular and staggered together for transportation, that is, four support frames are stacked, thereby reducing the space occupied and increasing the number of support frames on one side. The limit rods are provided to facilitate stacking, and the limit rods are sequentially arranged near the ends of the first crossbar to reduce the difficulty of stacking.

[0014] Preferably, the first cross bar includes two hinged connecting rods and a fixing member for fixing the two connecting rods, and the ends of the two connecting rods away from each other are hinged to the first vertical rods on both sides respectively, and the fixing member includes a fixing plate fixedly connected to the lower surface of one of the connecting rods and a fixing bolt passing through the fixing plate, and the fixing bolt is threadedly connected to the other connecting rod.

[0015] By adopting the above technical solution, the first crossbar includes two hinged connecting rods and a fixing member, so that the support frame can be folded, stored and carried, thereby further reducing the space occupied during transportation.

[0016] Preferably, the fixing member further includes an abutting plate abutting against the fixing plate and a support rod fixedly connected to the lower surface of the abutting plate, and the bolt is passed through the abutting plate.

[0017] By adopting the above technical solution, since the first cross bar is hinged, its supporting strength will be reduced. For this purpose, a support rod is provided. After the two connecting rods are unfolded and arranged at the same level, the abutment plate is abutted against the fixed plate, and bolts are passed through the abutment plate and the fixed plate to be threadedly connected to the connecting rod. At this time, the support rod abuts against the ground to support the support frame.

[0018] Preferably, the lower end of the limiting rod is rotatably connected to the first cross bar, and the first cross bar is provided with a limiting member for limiting the rotation of the limiting rod.

[0019] By adopting the above technical solution, the lower end of the limit rod is rotated and connected to the first cross bar. When limiting is required, the limit rod is rotated to be parallel to the height direction of the support frame, and then limited by the limit piece. When transporting, in order to reduce the possibility of damage caused by pressure when the limit rod is exposed to the cross bar, the limit rod is rotated to be parallel to the length direction of the first cross bar, and then limited by the limit piece.

[0020] Preferably, the lower end of the limit rod is rotatably connected to a rotating rod, and the rotating rod is rotatably connected to the first cross bar. The limit member includes a limit bolt threaded through the rotating rod, and the first cross bar is provided with a second through-hole for the limit bolt to pass through. There are two second through-holes and they are respectively arranged close to the upper and lower surfaces of the first cross bar.

[0021] By adopting the above technical solution, the rotating rod is used to install the limit rod on the first cross bar. After the limit rod is rotated to the required position according to needs, the limit bolt is passed through and threadedly connected to the corresponding second through-hole to limit the rotation of the limit rod.

[0022] Preferably, the limiting member also includes a spring coaxially sleeved on the limiting bolt and a force block fixedly connected to the lower limiting bolt, the two ends of the spring are respectively fixedly connected to the surfaces of the force block and the limiting rod close to each other, and the second through-hole is a limiting hole for the limiting bolt to be slidably inserted.

[0023] By adopting the above technical solution and providing a spring, the limiting of the limiting rod can be accelerated.

[0024] Preferably, the limiting rod is arranged on the inner surface of the first cross bar close to the second cross bar.

[0025] By adopting the above technical solution, the limiting rod is arranged on the inner surface of the first cross bar close to the second cross bar, which can reduce the possibility of falling or being damaged after a collision when it is placed outside the first cross bar.

[0026] In summary, the present invention has the following beneficial effects:

[0027] Since the length of the steel strand is relatively long, several support frames are provided so that relatively small support frames can be made for transportation to the site. It is also convenient to select a corresponding number of support frames according to the length of the steel strand and arrange them to form a relatively long placement platform to reduce the wear of the steel strand when it is placed on the ground. It also has a certain height so that the on-site staff can bundle several steel strands on the platform. After bundling, they are lifted by a crane for subsequent other construction work, thereby reducing the difficulty of passing the steel strands one by one through the corrugated tube and the corresponding time spent. Among them, the setting of the support roller is to pull the steel strand to reduce damage to the outer surface of the steel strand. The setting of the limit rod is to limit the movement range of the steel strand. Since it has a certain width, it is convenient for arrangement and combing. BRIEF DESCRIPTION OF THE DRAWINGS
