Description

Technical Field

[0001] The invention relates to the technical field of stair anti-skid groove construction between buildings, and more particularly to a groove pressing tool for forming cement mortar step anti-skid grooves. Background Art

[0002] With the rapid development of the construction industry, stairs, as an important connecting part inside buildings, have received more and more attention for their safety and aesthetics. Especially in public buildings or high-rise residential buildings, the safety of underground stairwells is particularly important. Therefore, anti-slip measures are usually required for each step during design. Traditional cement mortar stair treads are very easy to cause slip accidents in humid environments due to their smooth surface. Therefore, anti-slip grooves need to be made on the steps to increase friction and improve safety.

[0003] However, there are no standardized tools on the market specifically for making anti-skid grooves for cement mortar stair treads at this stage. Construction units usually use simple homemade tools for operation. These tools often lack precision, resulting in problems such as uneven straightness and uneven depth in the constructed anti-skid grooves, which not only affects the overall appearance of the stairs, but more importantly, reduces the anti-skid effect and cannot meet the requirements of quality standards. In addition, since the anti-skid grooves are grooves made during the one-time molding process of the cement mortar surface layer, once quality problems occur, such as the anti-skid grooves are not straight or the depth is not enough, it will be difficult to solve them with simple repairs. It is often necessary to chisel the entire structure and re-construct it, which not only increases the project cost, but also prolongs the construction period.

[0004] Therefore, how to propose a new type of simple, high-quality grooving tool for forming anti-slip grooves of cement mortar steps is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] Therefore, the object of the present invention is to provide a groove pressing tool for forming a cement mortar step anti-skid groove in a simple and high-quality manner, so as to overcome the defects in the background technology.

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Since there are currently no standardized tools specifically for making anti-slip grooves for cement mortar stair treads, construction units usually use homemade simple tools for the operation. These tools often lack precision, resulting in problems such as uneven straightness and depth in the constructed anti-slip grooves, which not only affects the overall appearance of the stairs, but more importantly, reduces the anti-slip effect and fails to meet the requirements of quality standards.

[0030] In view of this, the present invention provides a groove pressing tool for forming a cement mortar step anti-skid groove, see the attached Figure 1-3 , including: a main body 1, a limiting portion 3 and a positioning construction portion 4, the limiting portion 3 is located at one end of the main body 1 and extends downward; the positioning construction portion 4 is located at the bottom of the main body 1 and close to the limiting portion 3.

[0031] When the technical solution of the present invention processes the anti-skid grooves on the newly built stair treads, it is processed by the positioning construction part 4 under the guidance of the main body 1. This changes the problems of inconvenient construction operation when the existing workers rely on the means to arbitrarily press the anti-skid grooves, the anti-skid grooves made are not uniform and standardized, the production is time-consuming and labor-intensive, and the production effect cannot be guaranteed. When the production tool provided by the present invention is used to make the anti-skid grooves of the stair treads, since the positioning construction part 4 for making the anti-skid grooves is completed under the guidance of the main body 1, the uniform standards of the anti-skid grooves made in different parts can be guaranteed. With the guidance, the operation method can also be guaranteed, the difficulty of operation is reduced, and the purpose of saving time and effort is achieved. The limiting part 3 ensures that the anti-skid grooves formed by the positioning construction part 4 on each stair tread are consistent.

[0032] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] Advantageously, in the embodiment of the present invention, the main body 1 is a rectangular structure. The main body 1 can be a hollow structure or a solid structure, and the main body 1 serves as a guide for machining the anti-slip groove.

[0034] A handle 2 is installed on the top of the main body 1 , and the handle 2 has the same width as the main body 1 .

[0035] Advantageously, in the embodiment of the present invention, the limiting portion 3 is a limiting plate, which is perpendicular to the end of the main body 1 and at least part of the structure extends downward to form a stair end stop surface, thereby ensuring that each anti-slip groove is positioned consistently on the stair tread.

[0036] More advantageously, the embodiment of the present invention further comprises an extension plate arranged perpendicularly to the limiting portion 3 and located at the end of the main body 1. The extension plate is convenient for use with the handle 2 when processing the anti-slip groove, ensuring that the main body 1 can be stably placed on the stair step and the pressing depth of the anti-slip groove is consistent.

[0037] Specifically, the bottom of the main body 1 is provided with a pressing groove, the number of which is consistent with the number of anti-slip grooves of the stair treads, and the positioning construction part 4 is strip-shaped or column-shaped, fixed in the corresponding pressing groove, and protrudes 4-6 mm from the bottom end of the main body 1. The positioning construction part 4 can be a metal processing strip.

[0038] In the present invention, the main body 1, the limiting portion 3 and the positioning construction portion 4 are all in the same width direction.

[0039] When the tool provided by the present invention is used to make the anti-skid groove of the stair treads, the main body 1 is made of the existing channel steel, and the anti-skid groove is processed according to the groove depth. Two grooves are cut at the bottom of the main body using the channel steel (the number of grooves is consistent with the number of anti-skid grooves of the stair treads), and two φ8 round steels (metal processing strips) are laid in. The round steel protrudes about 5mm from the bottom plane of the main body. When applying the groove, the round steel can hook an anti-skid groove with basically the same depth on the mortar surface. The two ends of the round steel are polished into rounded corners to prevent the edges and corners from scratching the mortar surface and generating burrs during the grooving operation. The surface of the main body is polished smooth with sandpaper. When applying the groove, the smooth surface plays the role of the iron trowel to close the surface, and the closing surface and the groove applying are formed at one time.

[0040] In this way, the uniform specifications of the anti-skid grooves made in different parts can be ensured. With the main body guide, the difficulty of the operation method is reduced, and the purpose of saving time and labor is achieved. In the above implementation, combined with the characteristics that the operation space is usually limited in on-site construction and basically all operations are performed by personnel, in order to reduce the labor intensity of the operators and ensure the production quality of the anti-skid grooves, the structure of the main body 1 is simplified, and the processing and production of the main body 1 is convenient.

[0041] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" 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. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The method for manufacturing the anti-skid groove of stair treads of the present invention comprises the following steps:

[0043] S1. The cement mortar surface layer was leveled and compacted, and the first pass was smoothed and smoothed before initial setting;

[0044] S2, controlling the main body 1 in a fixed position by using a metal processing strip;

[0045] S3. When applying the groove, lift the main body 1 slightly along the stair step, press the metal processing strip at one end, and apply the anti-skid groove once; if the anti-skid groove is not straight, the anti-skid groove must be filled with mortar, and the entire step surface must be re-polished before applying the groove again. It is strictly forbidden to use the main body to apply the groove in the opposite direction.

[0046] S4. Carefully remove the main body, perform secondary calendering and smoothing on the step, and clean the excess mortar around the anti-slip groove, paying attention to keeping the shape of the positive and negative corners of the step square.

[0047] The process is repeated for processing a plurality of stair tread anti-skid grooves. The high-quality cement mortar tread anti-skid grooves formed by the tool of the present invention can effectively prevent the problems of the anti-skid grooves being not straight and having uneven depth, and improve the quality of the cement mortar tread anti-skid grooves.
