Description

Technical Field

[0001] The invention belongs to the technical field of concrete pouring, and in particular relates to a cast-in-place concrete finishing and grouting tool. Background Art

[0002] In cast-in-place concrete pouring projects, after the concrete is vibrated, the surface must be processed according to the project requirements. The method is to use a finishing grouting tool to repeatedly press and smear the concrete surface until the surface smoothness requirements required by the project are met. This process is called concrete finishing, which is closely related to the initial setting time of concrete. The key to the quality of finishing lies in time, which brings great uncertainty to the quality of concrete forming.

Although the cast-in-place concrete finishing and grouting tool adopts a cast-in-place concrete finishing panel made of plastic material, it is beneficial to improve the flatness of the concrete surface. In addition, the drainage holes on the cast-in-place concrete finishing panel are conducive to the overflow of cement slurry, so that the flatness of the concrete surface is further improved and the color is consistent. However, the structure of the cast-in-place concrete finishing grouting tool is relatively simple and has the following shortcomings: (1) there is only one working area to perform finishing grouting on the cast-in-place concrete surface by pushing, so the operator needs to grout repeatedly during the finishing grouting process, which reduces the operator's work efficiency; (2) it does not have an adjustment structure and a disassembly structure, and has poor flexibility. During use, the overall length of the device cannot be adjusted and the finishing panel cannot be replaced according to on-site needs.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features.

[0027] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0028] In the present invention, the "rear end" refers to the end that the operator holds in hand during use, and the "front end" refers to the end in the opposite direction.

[0029] See also Figures 1 to 4 In order to solve the above technical problems, the present invention provides a technical solution: a cast-in-place concrete surface grouting tool, the surface grouting tool comprising: a connecting support 1, a telescopic rod 2, a grouting block 3 and a rolling rod 4; the front end of the connecting support 1 is connected to the grouting block 3 through a first connecting frame 5, the rear end is movably connected to the telescopic rod 2, and the lower end is connected to an inverted U-shaped frame 7 through a second connecting frame 6, and the rolling rod 4 is rotatably connected between the two end legs of the inverted U-shaped frame 7.

[0030] In some embodiments, the first connecting frame 5 is bent at an obtuse angle or a right angle.

[0031] The bottom surface of the grouting block 3 and the surface of the rolling rod 4 are both flat and smooth, ensuring the flatness of the final concrete surface. The rolling rod 4 provided in the present invention is a cylinder, and the contact surface with the concrete is always a tangent line. Compared with the pressing panel whose contact surface is a surface, the surface grouting effect is better; and because the contact surface is small, it is conducive to squeezing out the bubbles in the concrete during the repeated surface recovery process. Compared with the setting of a single pressing panel in the prior art, the present invention simultaneously sets the grouting block 3 and the rolling rod 4 in front and behind, combines the surface line, and doubles the surface grouting, which significantly improves the surface grouting effect and work efficiency.

[0032] The front and rear sides of the bottom of the grouting block 3 described in the present invention are connected with arc-shaped baffles 31, and partitions 32 are respectively arranged between the left and right sides of each arc-shaped baffle 31 and the left and right sides of the grouting block 3 to achieve a sealing effect. The arrangement of the arc-shaped baffles 31 and the partitions 32 can prevent the concrete from contaminating the top of the grouting block 3 during the grouting process of the grouting block 3, which, on the one hand, avoids the waste of materials caused by contamination, and on the other hand, facilitates the subsequent cleaning of the grouting tool.

[0033] In some embodiments, a protective shell 8 is further provided between the rolling rod 4 and the inverted U-shaped frame 7. The protective shell 8 is fixedly connected to the two end legs of the inverted U-shaped frame 7. The protective shell 8 is used to prevent mud from splashing when the rolling rod 4 is working.

[0034] In some embodiments, the telescopic rod 2 includes an inner rod 21, an outer rod 22 and a tightening knob 23. The outer rod 22 is an internal hollow structure. The rear end of the inner rod 21 is movably sleeved in the outer rod 22. The bottom end of the outer rod 22 is threadedly sleeved with the tightening knob 23. In the specific use process, the tightening knob 23 can be loosened, and the length of the inner rod 21 in the outer rod 22 can be adjusted to the required length, and then the tightening knob 23 can be tightened to achieve the fixing effect. Figures 1 to 3 As shown, in this embodiment, the inner rod 21 is a threaded rod.

[0035] In some embodiments, the connection between the first connecting frame 5 and the grouting block 3 and the connecting support 1, and the connection between the second connecting frame 6 and the inverted U-shaped frame 7 and the connecting support 1 are: at least one end is a detachable connection. The setting of the detachable connection is, on the one hand, conducive to timely replacement of the grouting block 3 or the rolling rod 4 according to the usage or actual needs during use; on the other hand, it is conducive to the subsequent cleaning of the finishing grouting tool.

[0036] Furthermore, if Figure 1 and Figure 4 As shown, in this embodiment, the second connecting frame 6 and the connecting support member 1 are connected via a clamping ring 61 .

[0037] In some embodiments, the connection between the connecting support 1 and the telescopic rod 2 is hinged, which is used to flexibly adjust the angle between the telescopic rod 2 and the grouting block 3 and the rolling rod 4 to facilitate the use requirements of workers of different heights or different working conditions.

[0038] Furthermore, in some embodiments, the specific structure of the hinge is: the rear end of the connecting support 1 is provided with a groove 11 that passes through from top to bottom, the front end of the inner rod 21 is matched and inserted with the groove 11, the front end of the inner rod 21 and the side of the groove 11 are provided with through holes that pass through after insertion, and a fastening bolt 9 is provided that passes through the through hole to realize the movable connection between the connecting support 1 and the telescopic rod 2, so as to achieve the adjustment of different angles between the connecting support 1 and the telescopic rod 2.

[0039] In some embodiments, an outer surface of the outer rod 22 is clamped with an adjustable movable frame 10 , and an inner wall of the movable frame 10 is fixedly connected with a supportable cross bar 101 .

[0040] Specifically, when using the grouting tool of the present invention to work, the operation is as follows: first, the grouting block 3 and the rolling rod 4 are connected and installed with the connecting support 1 as required; then, according to the actual work requirements, the angle between the telescopic rod 2 and the connecting support 1 is adjusted by tightening the bolt 9, and the length of the telescopic rod 2 is adjusted by tightening the knob 23, which is convenient for the operator to work; the operator holds the outer rod 22 with one hand and the cross bar 101 with the other hand, and operates the connecting support 1, so that the connecting support 1 drives the grouting block 3 and the rolling rod 4 to move, thereby performing a double grouting treatment on the concrete. During operation, if it is found that the length of the telescopic rod 2 still does not meet the requirements, the length of the telescopic rod 2 can be adjusted by tightening the knob 23 until the requirements are met.

[0041] In summary, the present invention provides a cast-in-place concrete surface grouting tool, which includes a connecting support, a telescopic rod, a grouting block and a rolling rod. Compared with the single grouting panel setting in the prior art, the present invention simultaneously arranges a grouting block and a rolling rod in front and behind, combines the surface and line, and performs double surface grouting, which significantly improves the surface grouting effect and work efficiency; the tool of the present invention can adjust the working angle and length of the grouting tool according to the on-site work requirements, which is convenient for the operator to use and is conducive to improving work efficiency; in addition, the grouting block and rolling rod of the tool of the present invention are detachable structures, which is convenient for the operator to replace during use and clean after use, and has good market application prospects.
