Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipe positioning for precast beam slabs, and particularly relates to a corrugated pipe positioning frame. Background Technique

[0002] The corrugated pipe in the precast beam slab is mainly used to form a reserved hole for threading prestressed tendons to enhance the bearing capacity of the precast beam slab. The corrugated pipe plays a role of reserving a hole in the concrete. Through prestress technology, the bridge load can be shared, enabling the bridge to exhibit good deformation and seismic resistance capabilities, thereby extending its service life. In addition, due to its good plasticity and ductility, the corrugated pipe can effectively improve the bearing capacity and reduce the construction cost. When installing the corrugated pipe in the precast beam slab, a positioning frame is needed to position and install the corrugated pipe.

[0003] Currently, the corrugated pipe positioning frame used in precast beam slabs mainly consists of two vertical rods, a cross rod welded between the two vertical rods, and fastening rods installed on each cross rod. Although the corrugated pipe positioning frame with the above structure can achieve reliable positioning of the corrugated pipe in the precast beam slab during use, on the one hand, since the fastening rods in the corrugated pipe positioning frame with the above structure are fixed to the cross rod by welding, the fastening process is rather cumbersome, resulting in relatively low positioning and fastening efficiency after the corrugated pipe is placed. On the other hand, since the vertical distance between the cross rods in the corrugated pipe positioning frame with the above structure is fixed and cannot be flexibly adjusted according to the actual installation requirements of the corrugated pipe, the flexibility of the positioning frame in use is poor.

[0016] Furthermore, the fixed part of the spring rod is bolted to the groove, and the telescopic part of the spring rod is welded to the T-shaped plug board.

[0017] By adopting the above technical solution, the spring rod is mainly used to realize the automatic reset of the T-shaped plug board after being toggled.

[0018] Furthermore, the T-shaped plug board is slidably connected to the groove, and the size of the slot matches the size of the T-shaped plug board.

[0019] By adopting the above technical solution, after the T-shaped plug board is inserted into the corresponding slot on the fastening rod, rapid fastening and limiting of the fastening rod can be achieved.

[0020] Furthermore, the clamping wall of the fastening rod and the middle part of the upper end of the cross bar are both concave structures, and the fastening rod penetrates through the sliding hole.
