Description

Technical Field

[0001] This invention relates to concrete construction equipment, and more particularly to a concrete plastering construction device. Background Technology

[0002] In recent years, with the continuous development of tunnel construction technology in my country, new understandings have emerged regarding the requirements for invert construction in order to effectively improve the stability and durability of the invert structure. The formwork for invert construction has evolved from simple single-piece small formwork to integral low-sidewall invert formwork driven by trestle bridges, and further optimized to full-width invert formwork covering the entire invert cross-section. Using full-width invert formwork for the tunnel invert layer increases formwork costs and further compresses the construction space. During pouring, the invert layer is below the formwork, making full vibration impossible. In practical construction, air bubbles easily form on the final invert concrete surface. The presence of full-width invert formwork also prevents the application of slurry finishing and timely secondary cleaning of the invert layer surface. These air bubbles affect the appearance of the invert layer and also pose certain safety risks. Therefore, existing technology proposes a sliding invert formwork, also known as a drag formwork. The invert formwork is divided into left and right parts and equipped with arc-shaped tracks with the same shape as the invert surface. The left and right parts of the formwork can slide left and right along the arc-shaped tracks. Sliding formwork overcomes the above defects to some extent, but it still cannot guarantee the smoothness of the invert arch surface. Especially for water diversion culverts, the continuous scouring action of water flow will produce pits of various sizes, which will spread rapidly and seriously affect the service life of the project. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a concrete plastering construction device that is simple in structure, reliable, easy to use and has high construction efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A concrete plastering construction device includes a longitudinal track, a transverse track movable along the longitudinal track, and a movable seat movable along the transverse track, wherein a plastering roller is provided on the movable seat.

[0006] As a further improvement to the above technical solution: the smearing roller is provided with multiple rollers along the length direction of the transverse track.

[0007] As a further improvement to the above technical solution: the smearing roller is provided with multiple rollers along the length direction of the longitudinal track.

[0008] As a further improvement to the above technical solution: the finishing roller includes a rotating body, a top-arched roller, and / or a cantilevered roller. The top-arched roller includes a rotating body and multiple top-arched pieces arranged along the circumference of the rotating body. One end of the top-arched piece is fixedly connected to the rotating body, and the other end overlaps with the rotating body, or both ends of the top-arched piece are fixedly connected to the rotating body. The cantilevered roller includes a rotating body and multiple arc-shaped cantilevered pieces arranged along the circumference of the rotating body. One end of the cantilevered piece is fixedly connected to the rotating body.

[0009] As a further improvement to the above technical solution: the longitudinal track has two columns, the transverse track is located between the two columns of the longitudinal track, the transverse track has two columns, and the moving seat and the smearing roller are located between the two columns of the transverse track.

[0010] Compared with the prior art, the advantages of the present invention are as follows: The concrete plastering construction device disclosed in the present invention allows the transverse track to move along the longitudinal track, and the moving seat and plastering roller to move longitudinally along the transverse track. At the same time, the moving seat can move along the transverse track, and the plastering roller can move laterally along the moving seat. Therefore, the moving range of the plastering roller can cover the entire concrete surface. The rolling of the plastering roller makes the uneven concrete surface smooth and flat. By setting the shape of the corresponding longitudinal and transverse tracks, the plastering path can be controlled, realizing the forming and plastering of concrete surfaces of any shape, such as plane, unidirectional curved surface, bidirectional or multidirectional curved surface. Moreover, the structure is simple, reliable, and easy to use. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Figures 1 to 7 An embodiment of the concrete plastering construction device of the present invention is shown. This embodiment of the concrete plastering construction device includes a longitudinal track 1, a transverse track 2 movable along the longitudinal track 1, and a movable seat 3 movable along the transverse track 2. A plastering roller 4 is mounted on the movable seat 3. A power wheel can be installed on the transverse track 2, allowing the transverse track 2 to move actively along the longitudinal track 1. Alternatively, a drive mechanism can be installed on the longitudinal track 1, driving the transverse track 2 to move along the longitudinal track 1. The drive mechanism can be, for example, a sprocket and chain, with a corresponding transmission sprocket or hydraulic cylinder on the transverse track 2. Similarly, the movable seat 3 can move actively along the transverse track 2, or a drive mechanism can be installed on the transverse track 2, driving the movable seat 3 to move along the transverse track 2. The plastering roller 4 can be driven by a rotational force to achieve active rotation, or it can passively rotate after contacting the concrete surface during movement. See details below. Figure 1 and Figure 3 The longitudinal track 1 and the transverse track 2 can be, for example, straight tracks or curved tracks, and conform to the concrete forming surface.

[0021] This concrete plastering construction device has a transverse track 2 that can move along the longitudinal track 1. The moving seat 3 and the plastering roller 4 can move longitudinally along the transverse track 2. At the same time, the moving seat 3 can move along the transverse track 2, and the plastering roller 4 can move laterally along the moving seat 3. Therefore, the moving range of the plastering roller 4 can cover the entire concrete surface. The rolling of the plastering roller 4 makes the uneven concrete surface smooth and flat. By setting the shape of the corresponding longitudinal and transverse tracks 2, the plastering path can be controlled to realize the forming and plastering of any shape of concrete surface, such as plane, unidirectional curved surface, bidirectional or multidirectional curved surface. Moreover, this concrete plastering construction device has a simple and reliable structure and is easy to use.

[0022] See details Figure 4 As a preferred technical solution, multiple finishing rollers 4 are provided along the length of the transverse track 2 and along the length of the longitudinal track 1. During the longitudinal and transverse movement of the moving seat 3, multiple finishing rollers 4 can perform finishing successively, which helps to ensure the smoothness of the concrete surface.

[0023] See details Figure 6 and Figure 7 The finishing roller 4 can consist only of a rotating body, a top-arched roller, and / or a cantilevered roller. The top-arched roller includes a rotating body and multiple top-arched sections 42 arranged along the circumference of the rotating body. One end of each top-arched section 42 is fixedly connected to the rotating body, and the other end overlaps with the rotating body; alternatively, both ends of each top-arched section 42 may be fixedly connected to the rotating body. The cantilevered roller includes a rotating body and multiple arc-shaped cantilevered sections 41 arranged along the circumference of the rotating body. One end of each cantilevered section 41 is fixedly connected to the rotating body. During rolling, the top-arched and cantilevered rollers facilitate passing over and pressing down protruding aggregates on the concrete surface, preventing the protruding aggregates from moving and creating indentations on the concrete surface. The generatrix of the finishing roller 4 can be a straight line, an arc, a multi-segment line with a stepped structure, etc., specifically determined according to the requirements for concrete surface shaping.

[0024] As a preferred technical solution, the longitudinal track 1 has two rows, the transverse track 2 is located between the two rows of longitudinal tracks 1, and the transverse track 2 has two rows. The moving seat 3 and the finishing roller 4 are located between the two rows of transverse tracks 2, which ensures good overall balance and stability of the concrete finishing construction device. See details. Figure 5 Of course, in other embodiments, the longitudinal track 1 and the transverse track 2 may also have other structural forms, as long as the moving range of the troweling roller 4 can cover the entire concrete surface.

[0025] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
