Problems solved by technology

However, there will be gaps between two adjacent sections of film, causing water in the concrete to easily overflow from the gaps to the outside air after evaporation, which is not good for the health and maintenance of concrete.

Embodiment 1

[0037] like Figure 1-6 As shown, a bridge deck concrete curing device for highway engineering and bridge construction proposed by the present invention includes a membrane cylinder 200, an installation structure, a heating roller 1, a roller shaft 2, a glue barrel 3, a fixing frame 10 and a walking device.

[0038]The heating roller 1 is located behind the film drum 200. The heating roller 1 includes a roller body 101, a ring pressing portion 102 and a boss portion 103 that are integrally formed. The roller body 101 is a drum-shaped structure, and the ring pressing portion 102 is a disc-shaped structure. There are two ring pressing parts 102 in total, and the two ring pressing parts 102 are coaxially arranged at both ends of the roller body part 101 in the axial direction; On the peripheral surface, the side surface of the boss portion 103 away from the roller body portion 101 is a convex arc-shaped surface, and a plurality of boss portions 103 are evenly arranged around the ...

Embodiment 2

[0051] like Image 6 As shown in the figure, compared with the first embodiment, the width of the boss portion 103 gradually decreases along the radial direction of the roller body portion 101 in the present invention, which is compared with the first embodiment. Both sides of the boss portion 103 are inclined surfaces, which can smoothly separate from the film after rolling the film.

[0052] Chamfers are provided at both axial ends of the ring pressing portion 102, and the end of the boss portion 103 is connected to a chamfered corner in the ring pressing portion 102, so that the entire heating roller 1 can be more smoothly separated from the connected portion of the two films .

Embodiment 3

[0054] like image 3 As shown, the present invention proposes a bridge deck concrete curing device for highway engineering bridge construction. Compared with the first embodiment, in this embodiment, the switching mechanism includes a baffle plate 4, a fixed plate 5, an electric push rod 6, a plastic bucket 3 The lower part is provided with a channel for the baffle 4 to pass through, the baffle 4 is sealed with the inner wall of the channel, the glue will not overflow, the output end of the electric push rod 6 is connected with the baffle 4, and the electric push rod 6 is arranged on the fixed plate 5, fixed The plate 5 is arranged on the glue barrel 3 . The baffle 4 can be driven to move by the electric push rod 6, and the blocking and unblocking of the glue outlet channel can be realized by the sliding of the baffle 4 at the channel.

Abstract

The invention relates to the field of concrete curing, in particular to a bridge deck concrete curing device for highway engineering bridge construction. The device comprises a film cylinder, a mounting structure, a heating roller, a roller shaft, a glue barrel, a fixing frame and a walking device, the heating roller is located behind the film cylinder and comprises a roller body part, two annular pressing parts and a boss part which are integrally formed, the roller body part is of a drum-shaped structure, the annular pressing parts are of a disc-shaped structure, the two annular pressing parts are coaxially arranged at the two axial ends of the roller body part, and the boss part is arranged on the circumferential face of the roller body part in the direction from one end of the roller body part to the other end of the roller body part; the surface of the side, away from the roller body part, of each boss part is an outwards-protruding arc-shaped surface, the multiple boss parts are evenly arranged around the roller body part, and a groove is formed between every two adjacent boss parts and the roller body part; the heating roller is arranged on the roller shaft, the roller shaft is rotationally arranged on the walking device, and a glue outlet channel is formed in the lower portion of the glue barrel. According to the invention, films at any two adjacent ends can be connected when the films are laid so as to reduce water evaporation loss.

Description

technical field [0001] The invention relates to the field of concrete maintenance, in particular to a bridge deck concrete maintenance device for highway engineering bridge construction. Background technique [0002] Concrete curing is to artificially create certain humidity and temperature conditions, so that the freshly poured concrete can be normalized or accelerated its hardening and strength growth. The reason why concrete can gradually harden and increase its strength is the result of cement hydration, and the hydration of cement requires certain temperature and humidity conditions. If this condition does not exist in the surrounding environment, the concrete needs to be cured manually. The health and maintenance of concrete can be realized by laying plastic film, so that the water in the concrete is not easily evaporated, and the film can ensure that the humidity and temperature of the concrete meet the conditions of cement hydration.
