Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a sponge trowel. In addition, the utility model also relates to a wall painting device comprising the sponge trowel. Background Art

[0002] In the field of concrete wall construction technology, slipform projects are generally plain concrete walls. However, after the slipform is lifted, the concrete wall layer out of the mold has very obvious template marks, a large number of pores and sand holes, and further slurry and finishing treatment is required. The amount of work required to smooth and finish the slipform wall is large, and special tools are needed to improve the efficiency of smoothing and ensure the quality of construction. For example, a brush-type wall texture tool disclosed in a Chinese patent with patent publication number CN217759837U fixes the bristles through a limit assembly, and the limit assembly is driven by a moving assembly to operate, and different bristles can be replaced to meet the needs of wall construction. However, the above scheme has a relatively complex structure and a high production cost.

[0003] A simpler method is to use cement slurry filtered from the same concrete, apply it to the new concrete wall layer with a brush, repeatedly smooth it with a wooden or plastic trowel, and then smooth it with a steel trowel. Since the brush takes less slurry each time, it needs to be dipped multiple times for repeated brushing. However, there are the following problems: the brush takes less slurry each time, so it needs to be dipped multiple times for repeated brushing. Frequent operations can easily fatigue the operator, and the brush is easy to slip out of the hand; the slurry applied by the brush drips and stains the handle, and even the operator's hands and clothes; the slurry applied by the brush drips onto the wall below, which needs to be cleaned; the slurry applied by the brush cannot effectively cover all the pores and sand holes on the concrete wall at once. Utility Model Content

[0029] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0030] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of a sponge trowel provided by the utility model.

[0031] A sponge trowel, comprising:

[0032] The grout dipping body 5 is used to dip cement slurry and apply it to the wall surface;

[0033] The handle 3 is arranged on the dipping body 5, and a first mounting hole 2 is opened on the handle 3. A first hanging rope 1 is passed through the first mounting hole 2. The first hanging rope 1 is used to be tied to the operator's hand to prevent the operator from slipping out of the hand.

[0034] The "grouting body 5" herein means the main part of the sponge trowel that contacts with the cement slurry and absorbs the cement slurry to paint the wall. The structure of the grouting body 5 can be circular or polygonal. In reality, the grouting body 5 may also be irregular in shape due to cutting and forming by the sponge block. Of course, the present invention does not exclude the situation that the handle 3 and the grouting body 5 are regarded as one body and collectively referred to as the "grouting body".

[0035] The utility model uses a grouting body 5 to dip cement slurry to paint the wall, and the grouting body 5 is provided with a hand 3, and the handle 3 is provided with a first hanging rope 1, and the first hanging rope 1 can be used to tie the operator's hand to prevent the grouting body 5 from slipping out of the hand, which can effectively enhance the stability of the tool when painting the wall. Compared with a brush, a sponge trowel can dip more slurry at one time, which can reduce the number of times of dipping slurry and the dripping of slurry. At the same time, compared with a brush, the sponge trowel has a larger coverage area and can cover more pores and sand holes, effectively improving the efficiency and quality of construction.

[0036] Preferably, the dipping body 5 and the handle 3 are integrally cut and formed from a sponge block. It should be noted that the hardness grade of the sponge block is 45° to 55°.

[0037] It is understandable that the sponge trowel can be easily manufactured by integrally cutting a hard sponge with a higher Shore hardness, which is conducive to reducing costs.

[0038] Of course, the utility model does not exclude the technical solution of cutting out the dipping body 5 through the sponge and then using an additional plate to add to the dipping body 5 as the handle 3. Wooden boards or steel plates can be fixed to the dipping body 5 by screws or nails.

[0039] In some preferred embodiments, the dipping body 5 is a circular or square structure, and the handle 3 is an arc-shaped structure protruding away from the dipping body 5 .

[0040] It is understandable that the handle 3 of the arc structure is convenient to hold, which improves the comfort of the operator for holding for a long time. The round or square grouting body 5 has a larger contact area with the wall than the brush, and can cover a wider range of wall pores or sand holes. Since the grouting body 5 is made of hard sponge material, it can better absorb the slurry and reduce the dripping of the slurry.

[0041] In some preferred embodiments, the dipping surface 4 of the dipping body 5 is a spherical structure protruding outward.

[0042] It can be understood that the arc-shaped dipping surface 4 can improve the smoothness of the dipping body 5 during brushing, reduce the resistance of the dipping body 5 during brushing, and also reduce the bump damage on the edge of the dipping surface 4, which is beneficial to increase the service life of the dipping body 5.

[0043] Preferably, please refer to Figure 3 As shown, the sponge trowel further includes a handle cover 6 , which is detachably mounted on the handle 3 .

[0044] It is understandable that the connection between the handle 3 and the dipping body 5 is a frequently stressed point and needs better anti-bending ability. At the same time, the handle 3 itself also has the problem of bending, so the overall strength can be enhanced by adding the handle cover 6. At the same time, the handle cover 6 can be reused. By adding the handle cover 6, the height of the handle 3 can be reduced, so that the handle 3 only provides installation function, which is also conducive to reducing material costs.

[0045] In some embodiments, a skirt is provided at the bottom end of the handle cover 6, and the skirt serves to strengthen and support the dipping body 5.

[0046] The "skirt" here refers to the platform extending outward from the bottom end of the side plate 9 of the handle cover 6. The handle cover 6 can also be connected and fixed to the dipping body 5 by setting screw holes on the skirt to cooperate with bolts.

[0047] Preferably, please refer to Figure 4 As shown, the handle cover 6 includes a first clamping plate and a second clamping plate that are relatively arranged, and a connecting plate that connects the first clamping plate and the second clamping plate into a whole, and the gap between the first clamping plate and the second clamping plate forms a clamping groove for clamping the handle 3, and the clamping groove is provided with openings for the handle 3 to pass through at both ends along the length direction of the handle 3, and the width of one of the openings is greater than the thickness of the handle 3, and the width of the other opening is less than the thickness of the handle 3.

[0048] It can be understood that the strip-shaped slot between the two baffles 12 is the installation and removal hole 11. The installation and removal hole 11 is used to loosen and push out the handle 3 through a shovel or other tool when the handle cover 6 needs to be removed from the handle 3. When the handle 3 is installed, the position of the handle 3 can also be observed through the installation and removal hole 11.

[0049] Preferably, please refer to Figure 3 As shown, a plurality of third mounting holes 10 are spaced apart on the side panels 9 on both sides of the handle cover 6, and locking members are provided through the third mounting holes 10, which are used to sequentially penetrate the third mounting holes 10 and the handle 3 and fasten the handle cover 6 to the handle 3.

[0050] Specifically, the locking member is a bolt, a wire rope or a first hanging rope 1. When the locking member is the first hanging rope 1, the first hanging rope 1 is used to sequentially pass through the third mounting hole 10 and the first mounting hole 2 on the handle 3 and connect end to end to form a hanging ring.

[0051] It is understandable that the handle cover 6 can be quickly fixed on the handle 3 by the locking member. When the locking member is the first hanging rope 1, the handle cover 6 and the handle 3 can be connected by the first hanging rope 1, and the two ends of the first hanging rope 1 are connected to form a hanging ring, and the first hanging rope 1 is tied to the operator's hand to prevent the operator from slipping out of the hand. Of course, the handle cover 6 can also be fixedly connected to the handle 3 by bolts or steel wire ropes in combination with the first hanging rope 1 to improve the stability of the connection.

[0052] Of course, the present invention does not exclude that the side panels 9 of the handle cover 6 are structures that can be telescopically moved relative to each other. Specifically, the side panels 9 on both sides are connected by telescopic components such as telescopic rods or telescopic cylinders to achieve adjustable spacing between the side panels 9 on both sides to meet the installation requirements of handles 3 of more sizes and thicknesses, and the handle 3 can be clamped by the side panels 9 on both sides to achieve enhanced and stable installation.

[0053] In another preferred embodiment, the handle cover 6 includes a second hanging rope 7, a second mounting hole 8 is opened on the side panel 9, the second hanging rope 7 is inserted into the second mounting hole 8, and the second hanging rope 7 is used to be tied to the operator's hand to prevent it from slipping out of the hand.

[0054] It is understandable that when the handle cover 6 is installed on the handle 3, the first hanging rope 1 on the handle 3 can be removed, and the second hanging rope 7 on the handle cover 6 plays the role of tying the operator's hand to prevent it from falling off. It should be noted that if the first hanging rope 1 is used to connect the handle cover 6 to the handle 3, the second hanging rope 7 may not be provided.

[0055] Optionally, the first suspension rope 1 and the second suspension rope 7 are both elastic ropes or elastic belts.

[0056] According to another aspect of the utility model, a wall painting device is also provided, which includes the above-mentioned sponge trowel and a painting drive device, and the sponge trowel is installed on the painting drive device.

[0057] It should be noted that the painting drive device here can adopt a telescopic rod or a mechanical arm. The sponge trowel can be installed through the painting drive device to achieve efficient painting of walls of different heights, which can reduce the workers' frequent climbing of escalators, minimize dangers and reduce labor intensity.

[0058] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0059] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the utility model, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the protection of the utility model.
