Description

Technical Field

[0001] The utility model relates to the field of bridge engineering, and particularly relates to a telescopic shed for steam curing of precast T-beams. Background Art

[0002] Steam curing of precast T-beams is a method for curing concrete components, which is mainly applied in the production process of precast T-beams. This method cures the concrete by using steam to accelerate its hardening process, improve the strength and durability of the concrete. Most of the curing sheds adopt steel structure skeletons, and ordinary canvas is laid outside and fixed on the steel structure skeletons.

[0003] In the prior art, when curing precast T-beams, due to the different lengths of precast T-beams, and the length of the existing curing shed is usually not adjustable, it is impossible to adapt to the curing of precast T-beams of different specifications. At the same time, the sealing performance of the general curing shed is not good, and steam is easy to escape from the openings at both ends of the curing shed and the bottom gaps around the curing shed, which greatly affects the curing effect, resulting in poor quality of the finished precast T-beams and affecting the overall bearing capacity of the bridge.

[0004] Therefore, a telescopic shed for steam curing of precast T-beams is proposed to solve the above technical problems. Content of the Utility Model

[0005] The utility model provides a telescopic shed for steam curing of precast T-beams to solve the problems that the length of the curing shed in the prior art is not adjustable and the steam is easy to escape, resulting in poor quality of the finished T-beams.

Detailed Implementation Modes

[0022] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems to be solved, the technical features constituting the technical solutions, and the technical effects brought.

[0023] AsFigures 1 to 3 As shown in the figure, a telescopic shed for steam curing of precast T-beams includes:

[0024] The shed frame 1 is in a portal shape and is provided with sliding wheels at the bottom; several shed frames 1 are provided, and all are provided with vertical sliding grooves 2;

[0025] The cross strut is two support rods 3 hinged at the midpoint. The tops of the two support rods 3 are respectively rotatably connected to the shed frames 1 on both sides, and the bottoms respectively slide in the sliding grooves 2 of the shed frames 1 on both sides to connect two adjacent shed frames 1;

[0026] The side tarpaulin 4 is longer than the height of the shed frame 1, covers the shed frame 1 and is fixedly connected to the shed frame 1. A first magic sticker 5 is provided at the bottom, and the first magic sticker 5 is pasted on the second magic sticker 6 in the middle and lower part of the side tarpaulin 4;

[0027] The driving motor 7 is horizontally arranged on the shed frames 1 at both ends, and the output shaft is connected with a winding roller 8;

[0028] The first end tarpaulin 9 is fixedly connected to the winding roller 8 at one end and is provided with a counterweight rod 11 at the other end;

[0029] The second end tarpaulin 10 is sewn to the upper part of the side tarpaulin 4 and covers the end face of the shed frame 1 above the driving motor 7.

[0030] The curing shed of the device of the present utility model adopts a telescopic structure. By moving the shed frame 1 to drive the cross strut to unfold or contract, the length of the curing shed can be adjusted to meet the steam curing requirements of precast T-beams of different lengths. The side tarpaulin 4 is arranged on the shed frame 1, covering the side and top of the shed frame 1. When the curing shed is in the contracted state, the side tarpaulin 4 is folded, and when the curing shed is unfolded, the side tarpaulin 4 is stretched to meet the requirement of preventing steam from overflowing from the side, and at the same time, it is also convenient for the transportation of the device of the present utility model. When moving or adjusting the length of the curing shed, the first magic sticker 5 is pasted on the second magic sticker 6 to prevent the side tarpaulin 4 from dragging on the ground. When the shed frame 1 moves to the place, the first magic sticker 5 is removed from the second magic sticker 6, so that the bottom end of the side tarpaulin 4 is lowered to the ground, avoiding steam overflow caused by the gap between the side tarpaulin 4 and the ground and ensuring the curing effect. In addition, by driving the winding roller 8 to rotate through the driving motor 7, the first end tarpaulin 9 is raised or lowered at the end of the shed frame 1, so that the first end tarpaulin 9 can avoid dragging on the ground during movement and can completely cover the end face of the entire shed frame 1 after the length or position of the curing shed is adjusted, further avoiding the gap caused by steam overflow and ensuring the curing effect. The counterweight rod 11 can also ensure that the whole first end tarpaulin 9 can be in a natural drooping state.

[0031] As a preferred embodiment, the top end of the support rod 3 is rotatably connected to the shed frame 1 through a first pin shaft 12. A pin shaft groove is formed at the bottom end. One end of a second pin shaft 13 passes through the support rod 3 and the sliding groove 2 and is provided with a limiting block, and the other end is provided with a locking nut.

[0032] In this embodiment, a specific connection method between the support rod 3 and the shed frame 1 is provided. Among them, the top of the support rod 3 is rotatably connected to the shed frame 1 through the first pin shaft 12, so that the overall position of the support rod 3 on the shed frame 1 will not change. And at the bottom end, after the second pin shaft 13 passes through the two support rods 3 and the sliding groove 2, the two ends of the second pin shaft 13 are respectively limited by the limiting block and the locking nut, so as to realize the free up and down movement of the second pin shaft 13 in the sliding groove 2, so as to realize the mutual approach or separation of the shed frames 1, so as to achieve the purpose of adjusting the length of the maintenance shed.

[0033] As a preferred embodiment, a sliding track is provided on the ground, and the shed frame 1 moves within the sliding track.

[0034] In this embodiment, by providing a sliding track on the ground, it is avoided that during the process of moving the maintenance shed from one precast T-beam to another precast T-beam position after the maintenance of one precast T-beam is completed, the maintenance shed is offset, resulting in too close a distance between the beam body of the precast T-beam and the maintenance shed, affecting the maintenance effect.

[0035] As a preferred embodiment, a door is also opened on the first-end tarpaulin 9.

[0036] In this embodiment, by opening a door on the first-end tarpaulin 9, when the staff needs to enter and exit the maintenance shed, it is not necessary to lift the entire first-end tarpaulin 4, thereby effectively reducing the steam overflow and ensuring the maintenance effect.
