A T-beam construction device for road bridges

Abstract

The present invention relates to the technical field of T-beam forming for road bridges, and more particularly to a T-beam construction device for road bridges, comprising a base formwork and two stripper frames located on either side of the base formwork and arranged along the length of the T-beam. The two stripper frames respectively comprise a fixed formwork, a movable formwork, and an auxiliary formwork. The movable formwork and the fixed formwork are connected by an adjustment device, which drives the movable formwork to move along the length of the fixed formwork, thereby adjusting the length of the stripper frame. Auxiliary formwork frames can then be added or removed between the movable formwork and the fixed formwork. The auxiliary formwork frames have various length specifications. This device solves the problem of the unadjustable formwork length in existing T-beam construction, making it difficult to adapt to the construction requirements of T-beams of different lengths. By means of the adjustment device, the movable formwork can move relative to the fixed formwork, quickly adjusting the length of the stripper frame, and improving construction efficiency and flexibility.

[0002] At present, the existing patent announcement number is CN209339001U, which is a T-shaped prefabricated bridge formwork, including a side formwork, a bottom formwork and an end formwork. The side formwork includes two side frames, and the two side frames are installed on both sides of the bottom formwork, and the end formwork is arranged at both ends of the bottom formwork and connected to the two side formworks. The side frame includes a locking frame and a side pressure plate. The side pressure plate is adapted to the side of the T-shaped prefabricated bridge, and the locking frame is multiple and evenly arranged along the length direction of the side pressure plate, and the locking frame includes a support and a locking plate, the support is connected to the side pressure plate, and a card slot is provided on the top of the support, the locking plate is inserted in the card slot and is hingedly connected to the support, and a locking hole is provided on the top of the locking plate. The side frame is formed by combining the side pressure plate with the locking frame, the locking frame is formed by using the support and the locking plate, and a slot is set on the support. The locking plate and the support are hingedly connected through a rotating shaft. Therefore, during use, the problem of interference between the high density of the reinforcement ribs and the locking plate can be effectively avoided, making it more convenient and quick to use and avoiding the problem of strength reduction of the T-shaped prefabricated bridge caused by cutting the reinforcement ribs.

[0003] However, the above-mentioned prefabricated T-beam formwork also has some problems. The above-mentioned prefabricated T-beam formwork lacks an adjustment device, that is, it is difficult to cast bridge prefabricated parts of different lengths with one prefabricated T-beam formwork. That is, when bridge prefabricated parts of different lengths need to be cast, a new prefabricated T-beam formwork needs to be replaced, which not only increases construction costs but also reduces construction efficiency.

[0018] 6. The setting of the support rod plays a role in positioning and supporting the movement of the movable mold frame to a certain extent;

[0019] 7. Multiple nuts are used to secure the fixed and auxiliary formwork, as well as the movable and auxiliary formwork. This connection facilitates assembly and disassembly of the formwork, improving construction convenience and efficiency. Furthermore, the nut-secured connection offers high strength and stability, ensuring the overall performance of the stripper during the pouring process. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Among them, the fixed formwork 21, the movable formwork 22 and the auxiliary formwork 23 all include a plurality of channel steels 201 spaced apart and arranged in parallel, a column assembly 202 arranged on one side of the channel steel 201 for fixing each channel steel 201, and a template 203 arranged on the other side of the channel steel 201. The adjusting device 3 is arranged on the column assembly 202 of the movable formwork 22 and the fixed formwork 21.

[0033] In this embodiment, the adjusting device 3 includes a plurality of holders 31, at least two parallel fixed rods 32 and a driving mechanism 33.
