Description

Technical Field

[0001] The invention relates to the technical field of construction tools, in particular to a quick and easy tool for cutting grooves and forming anti-slip strips for stair treads. Background Art

[0002] There are many construction measures and tools for anti-skid grooves in stair treads of construction projects, and the construction quality and efficiency are also different. How to ensure that the anti-skid grooves of stair treads are efficiently formed in one time and have a good anti-skid effect is particularly critical. The traditional cement mortar plastering stair tread anti-skid groove construction method usually uses a metal strip to measure and align the initial setting mortar surface with the groove. During the groove pressing process, the volume of the groove pressing metal strip invades the initial setting mortar, and the mortar surface of the grooved part is squeezed and deformed. While the groove is formed, the mortar surface near the anti-skid groove is destroyed. It is also necessary to repeatedly use a trowel to water-polish the affected deformation range. Not only is the work efficiency low and the molding effect unsatisfactory, but the anti-skid grooves of the steps are often missing.

[0003] In order to solve the above technical problems, workers used waste materials from the construction site to make simple tools, such as Figure 3 As shown, it includes an integrally formed stainless steel folding plate structure, the outer corners of the folding plate structure are rounded, two integrally formed anti-skid grooves are provided on the horizontal section of the folding plate structure, and a handle is provided at the top of the folding plate structure. When in use, the anti-skid groove is cut through the groove, and the outer corners of the stair treads are processed through the rounded corners of the folding plate structure. Although the device greatly improves the efficiency of construction and reduces the difficulty of construction, it still has the following defects:

[0004] 1. The stainless steel folding plate structure is prone to deformation. Once deformed, it is difficult to repair, which will cause the stair treads to be uneven and the anti-slip groove size to not meet the requirements, and can only be discarded.

[0005] 2. When the inner diameter of the anti-slip groove and the radius of the rounded corner of the stair tread change, new tools have to be prepared, resulting in poor versatility of the tool. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in this new type in conjunction with the drawings in the embodiments of this new type. Obviously, the described embodiments are only a part of the embodiments of this new type, rather than all of the embodiments. Based on the embodiments in this new type, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of this new type.

[0026] The following embodiments can be understood as separately explaining the local structure of this new type, or can be understood as explaining the structure of a larger range of this new type through the combination of multiple embodiments.

[0027] In this embodiment, a quick and easy tool for grooving and forming anti-slip strips on stair treads is as follows Figure 1 , 2 shown, including a first plate body 2 for fitting the horizontal plane of the stair tread 14 and a second plate body 1 for fitting the vertical plane of the stair tread 14. The first plate body 2 is composed of a plurality of plate body segments 201 spliced together, and an anti-slip groove forming plate 3 is detachably and fixedly connected between adjacent plate body segments 201. A stair tread external corner forming plate 6 is detachably and fixedly connected between the upper end of the second plate body 1 and one end of the first plate body 2. An anti-slip groove width control mechanism is provided at the upper end of the first plate body 2.

[0028] In a further embodiment, as Figure 1 , 2 shown, the first plate body 2 is composed of 3 plate body segments 201 spliced together. The anti-slip groove forming plate 3 includes a first arc-shaped plate structure, and connecting plates 7 are provided longitudinally at both ends of the first arc-shaped plate structure. The connecting plates 7 are detachably and fixedly connected to the ends of adjacent plate body segments 201.

[0029] In a further embodiment, as Figure 1 , 2 shown, the external corner forming plate 6 includes a second arc-shaped plate structure. The inner surface of the second arc-shaped plate structure and the inner surfaces of the first plate body 2 and the second plate body 1 form a continuous surface. Both ends of the second arc-shaped plate structure are detachably and fixedly connected to the end of the first plate body 2 and the top end of the second plate body 1.

[0030] In a further embodiment, as Figure 1 , 2 shown, the thickness of the first arc-shaped plate structure is less than the thickness of the second arc-shaped plate structure. The first arc-shaped plate structure can directly cut and form the anti-slip groove.

[0031] In a further embodiment, as Figure 1 , 2 shown, the second arc-shaped plate structure, the first plate body 2, and the second plate body 1 have the same thickness, and cutting edges 15 are provided at both ends of the second arc-shaped plate structure. The cutting edges are used to cut the external corners of the stair treads.

[0032] In a further embodiment, as Figure 1 , 2 shown, dovetail grooves 4 are respectively provided at the top end of the second plate body 1 and both ends of the plate body segment 201. The outer ends of the connecting plates 7 and both ends of the second arc-shaped plate structure are respectively tightly fitted with the corresponding dovetail grooves 4 through dovetail blocks 5.

[0033] In a further embodiment, as Figure 1 , 2As shown, the first arc-shaped plate structure and the second arc-shaped plate structure are provided with several models according to the difference in inner diameter and can be quickly replaced according to construction needs.

[0034] In a further embodiment, as Figure 1 , 2 shown, the anti-slip groove width control mechanism includes mounting plates 8 longitudinally arranged at the upper ends of several plate segments 201. The several mounting plates 8 are parallel to each other and perpendicular to the length direction of the first plate body 2. Two screw rods 10 arranged side by side are horizontally connected between the several mounting plates 8. One end of the screw rod 10 is fixedly connected to the outer surface of the mounting plate 8 close to one end of the second plate body 1. Threaded segments 11 are provided on the rod bodies at the positions where the screw rods 10 are connected to the other mounting plates 8. Scaled segments 12 are formed on the rod bodies except for the threaded segments 11 with scale lines for measuring length. The screw rods can slidably penetrate the other mounting plates. Nuts 9 are screwed on the threaded segments 11 on both sides of the other mounting plates. The two nuts 9 are in close fit with the outer surfaces of the corresponding mounting plates. In this embodiment, when it is necessary to replace the anti-slip groove forming plate 3 with a different inner diameter, only the original anti-slip groove forming plate 3 needs to be pulled out. Then, the nuts are loosened, the plate segments are moved so that the distance between adjacent plate segments matches the size of the anti-slip groove forming plate 3 to be installed, the nuts are tightened, and then the anti-slip groove forming plate 3 is inserted. When the size of the anti-slip groove forming plate 3 does not match, it indicates that the model may be incorrect or the anti-slip groove forming plate 3 has undergone a large deformation, and a qualified anti-slip groove forming plate 3 needs to be replaced, thereby effectively controlling the size of the anti-slip groove. The replacement principle of the outer corner forming plate 6 is the same as this.

[0035] In a further embodiment, as Figure 1 , 2 shown, indicating plates 13 are longitudinally and fixedly provided at the top edges of the opposite ends of adjacent plate segments 201. The indicating plates are used in cooperation with the scale lines. The scale corresponding to the edge of the plate segment can be quickly identified through the indicating plates, and thus the width of the anti-slip groove forming plate 3 can be quickly detected.

[0036] When this new type is in use, while the first plate body and the second plate body are attached to the surface of the not yet fully solidified concrete of the stair treads, the mutually connected first plate body and second plate body are inserted along the direction of the anti-slip groove. The anti-slip groove is cut and formed by the anti-slip groove forming plate 3, and the outer corner surface of the stair tread is cut and formed by the outer corner forming plate 6.
