Description

Technical Field

[0001] The utility model belongs to the technical field of bridge maintenance construction, and particularly relates to a simple concrete pouring device for T-beam reinforcement. Background Technique

[0002] With the passage of time and the continuous increase of traffic load, many bridges have gradually shown signs of aging and damage, including a large number of bridges with T-beam structures. The existence of dangerous and old bridges poses a serious hidden danger to traffic safety. On the one hand, the aging of the structure may lead to a decrease in the bearing capacity of the bridge, unable to meet the growing traffic demand. For example, the concrete of the T-beam may show cracks, spalling, etc., and the steel bars may also lose their original strength due to corrosion, thus affecting the overall stability of the bridge. On the other hand, the durability of dangerous and old bridges is reduced, and it is easily affected by natural environmental factors such as rain erosion and freeze-thaw cycles, further accelerating the damage process of the bridge.

[0003] One of the repair and reinforcement methods for T-beams is to set U-shaped steel plates at the bottom of the T-beams and pour concrete between the steel plates and the T-beams. For example, in the Chinese invention patent (CN118207808A) a strengthening structure for the web and bottom plate of an old concrete T-beam, including an outer steel plate, a UHPC (ultra-high performance concrete) thin layer, screws implanted into the old concrete T-beam, and firm nuts. After roughening and drilling the old concrete T-beam, the old concrete T-beam is wrapped with a steel plate, special glue for implanting steel bars is poured into the drilled holes of the old concrete T-beam, then screws are implanted through the old concrete T-beam and the steel plate, and then a UHPC thin layer is poured between the steel plate and the old concrete T-beam, and finally nuts are used to apply a tightening force to the screws.

[0004] When pouring concrete into the gap between the T-beam and the U-shaped steel plate, a chute is generally used. The existing chutes are mainly made temporarily on the construction site. The chute is not convenient to be quickly fixed to the U-shaped steel plate. After the chute is fixed, the angle of the chute cannot be adjusted, and it is not convenient to quickly adjust the position of the chute after it is fixed, resulting in low concrete pouring efficiency.

Specifically, partition plates 4183 are respectively arranged horizontally on both sides of the second sliding sleeve 418. The partition plates 4183 are arranged in parallel and at intervals above the extension plate 416. The partition plates 4183 are penetrated by second positioning bolts 4184 threadedly connected therewith. When it is necessary to fix the position of the second sliding sleeve 418, rotate the second positioning bolt 4184 so that its end abuts tightly against the top surface of the extension plate 416.

[0040] In one embodiment, a connecting rod 425 is provided between adjacent first sliding sleeves 423, which is convenient for synchronously adjusting multiple first support rods 421 and is beneficial to improving the convenience of adjusting the inclination of the chute 3.

[0041] When the simple concrete pouring device for T-shaped beam reinforcement is used, the first support plate 411 is inserted into the gap between the U-shaped steel plate 2 and the T-shaped beam 1, and the first support plate 411 is attached to the inner surface of the U-shaped steel plate 2. The threaded rod 419 is rotated through the hand-held part 415, driving the clamping plate 414 to move towards the outer surface of the U-shaped steel plate 2 and abut against it. The first support plate 411 and the clamping plate 414 cooperate to fix the clamping and fixing member 41 to the U-shaped steel plate 2. The height of the second end 6 of the chute 3 is adjusted by the first support rod 421, that is, the inclination of the chute 3 is adjusted. The positioning plate 4232 is lifted to separate the positioning plate 4232 from the positioning groove 4221. The second support rod 422 is slid, so that the baffle 424 abuts against the outer surface of the U-shaped steel plate 2. Under the action of the limit spring 4235, the lower part of the positioning plate 4232 is inserted into the corresponding positioning groove 4221. The first positioning bolt 4182 is rotated to fix the position of the second sliding sleeve 418 relative to the first support rod 421. At the same time, the second positioning bolt 4184 is rotated to fix the position of the second sliding sleeve 418 in the chute 4161. Through the cooperation of the clamping and fixing member 41 and the auxiliary support member 42, a stable support is formed for the chute 3, which is convenient for pouring concrete into the gap between the U-shaped steel plate 2 and the T-shaped beam 1 through the chute 3.
