Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction devices, in particular to a cement mortar arc forming device for multiple diameters. Background Art
[0002] Waterproofing is a crucial construction step for any building with anti-seepage design requirements. Its quality directly impacts the function and lifespan of the building, and is crucial for the smooth functioning of people's lives and production. However, pre-waterproofing requires high standards for the base layer. Applying waterproofing coatings to corners is challenging, as is laying the membrane at right angles, which can easily lead to hollowing. According to engineering practice and relevant waterproofing regulations, rounded corners (commonly known as "R-angles") should be mortared to effectively ensure the waterproofing quality of these areas. Traditionally, rounded R-angles are typically created using small plastering tools or a section of PVC pipe. This is cumbersome, time-consuming, and labor-intensive, resulting in mediocre quality. The resulting rounded shape is poor, resulting in uneven interfaces with vertical and horizontal surfaces, prone to misalignment and burrs. Furthermore, the required R-angle radius varies depending on the location, making it difficult to ensure effective waterproofing quality. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 are within the scope of protection of the present invention.
[0021] like Figure 1-5As shown, according to the utility model, a multi-diameter cement mortar arc forming device is disclosed, including a base plate 1, a rotating shaft 2 is provided on both sides of the upper surface of the base plate 1, the base plate 1 is connected to a linkage rod 3 through the rotating shaft 2, a slide rail 4 is provided at the top of the linkage rod 3, the center of the upper surface of the base plate 1 is connected to a connector 6 through a screw 5, a mounting hole is provided in the center of the connector 6, a screw hole is provided in the center of the slide rail 4, an adjusting rod 8 is installed on the connector 6 through the mounting hole, a knob 9 is installed on the upper part of the adjusting rod 8, and a handle 7 is provided at the end of the connector 6.
[0022] In one embodiment of the present invention, a slot is provided at the bottom end of the slide rail 4, and the linkage rod 3 is slidably connected to the slot; an adjustment thread is provided on the side of the adjustment rod 8, and an adjustment screw hole is provided in the knob 9, and the adjustment screw hole matches the adjustment thread on the side of the adjustment rod 8. The base plate 1 is made of stainless steel. The adjustment rod 8 with a thread that can be turned through the knob 9 is used to change the distance between the slide rail 4 and the base plate 1. The linkage rods 3 on both sides drive the edges of the base plate 1, causing the base plate 1 to bend and deform, forming a base plate 1 with a curvature. Different distances between the slide rail 4 and the base plate 1 cause different deformations of the base plate 1, thereby forming different curvatures.
[0023] During specific use, by turning the knob clockwise or counterclockwise, the linkage rod slides inward on the slide rail and drives the edges on both sides of the base plate to move upward, and the arc diameter changes from large to small as the clockwise rotation is performed; adjust the arc diameter to the required size, spread the mortar evenly on the inner corner of the wall root, hold the handle and press the mortar back and forth against the vertical and horizontal wall surfaces to achieve the ideal molding effect; after the construction is completed, the knob should be rotated counterclockwise to restore the base plate to its original state, and the residual mortar and dirt should be cleaned. The linkage shafts, slide rails and adjustment rods should be regularly greased to prevent rust from affecting normal use.
[0024] The device can be adjusted to different diameters by adjusting the screw rod, achieving the purpose of forming different diameters of cement mortar arcs. It can also be used in other plastering constructions with arc shapes. It is fast and convenient, with standard forming and good results. The arc size can be adjusted as required.
[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
