CN211597620U - Ceramic tile leveling tool bag - Google Patents

Abstract

The application relates to a tile leveling tool bag, which consists of a separating element, a wedge and a pair of pliers. The pliers comprise two jaws: an upper jaw and a lower jaw. The upper jaw is disposed between the tip and the handle and has an elongated opening through which a through bolt passes through the lower jaw. The distance between the two clamping jaws is adjusted through the convex grains and the grooves which are respectively arranged on the clamping jaws. The pliers are intended to press a wedge inserted into an arch opening belonging to the separating element. In addition to the existing types, the separating element can have a cross-shaped seat or a T-shaped seat, depending on the number of tiles placed at the separating element. The reinforcing element placed between the wedge and the tile to be leveled comprises a plate body that increases the pressure on the surface of the tile to be leveled.

Description

Ceramic tile leveling tool bag

Technical Field

The present application relates to construction tools, and in particular to tools for leveling tiles and cladding on floors and wallboards.

Background

The application or covering of wall panels and floors with tiles requires the constructor to perfectly level the edge lines and corners, which is not completely achieved despite hours of hard work and extra effort. In general, it is an advance to use manual levelers meter by meter. However, this is a task that the constructor must check several times, since the weight of the tile will eventually press the glue to one side, resulting in that this work can only be done by the most experienced construction constructor and requires a lot of effort and time.

Today, the application of tiles to wall and floor panels no longer requires that we spend so much time and much effort, since an arched door and wedge self-leveling device has been developed which, when properly placed between the tiles, can fix the tiles in line, without squeezing the glue due to uneven weight and preventing the corners of the tiles from sinking, thus achieving an even leveling of all the corners of the tiles.

This arch and chock self-leveling system comprises three important parts: a pair of pliers for connecting the parts; an arch (2A) with the widest base; and a wedge (6B) passing through the middle of the arch; when mated to each other, the parallel bases are caused to closely and securely overlap so that the tile surfaces are perfectly aligned with each other at the top and bottom.

In order to connect the parts, such a self-levelling system requires a force of more than 20 kg and is therefore inconvenient to operate by bare hands, it being necessary to use special pliers to press the two parts mentioned against each other in order for the wedges to press against the arched door.

In this arch and chock levelling system we have used a flat transverse arch (2A) only for jacking up tiles from bottom to top and a chock to push tiles in parallel from top to bottom, so that each time the arch acts on the junction of two parts, the two parts are placed in line. The special pliers developed for connecting the self-levelling instrument are complex and require continuous adjustment of the first opening by screwing and unscrewing the adjusting bolt, respectively, thus wasting valuable working time. Since they are manufactured on the basis of the need for this new arch and chock arrangement, during operation they first adjust the jaws from a small distance of less than 1 cm to a distance of 8 cm, keeping the gripping portion of the upper jaw with a shape similar to the arch post of the arch, to grip them. The lower jaw is adjusted to the rear of the wedge by attaching an extension handle, pushing the wedge into the arched door to generate a pressure in excess of 20 kilograms.

However, these pliers require a lot of time to do this. This work can be easily improved by our proposal, which is based on a dual pressure system and does not require separate bolts to lock or unlock as with other pliers.

The arch not only enables the leveling tiles to be lifted to the same level, but also enables the tiles to be aligned with the top wall four (7A) or three (3B) at a time, thus better aligning and separating all the leveling tiles; finally we have also noticed that in the case of joining three or four top walls, the wedges can exert a wider range of pressure on the levelling tiles, using means acting underneath them, when inserting the arch (6ABC), so as to optimize the jacking and pressing of the tiles.

An example of a prior leveling system is disclosed in AU patent No. 2016100036 entitled "tile spacer and leveler", published 2016, 8, 18, which discloses a tile leveling device that includes a spacer having a horizontal base that supports a vertical rod. Such a rod has an opening to accommodate a wedge inserted parallel to the base and one or more holes at the junction of the bases. The opening is rectangular and corresponds to the largest rectangular cross-section of a wedge having a V-shaped top edge, and the top surface of the wedge has a mating wave shape.

As part of the prior art, we can also refer to patent WO 2008118418 entitled "apparatus and method for leveling and aligning tiles" published on 10.2.2008, which provides a tile leveling device. The apparatus includes a main section, a first portion extending laterally from the main section to receive a first tile, and a second portion extending laterally from the main section in a direction opposite the first portion to receive a second tile. It also provides a means of passing through the main part and exerting a force on the tiles to flatten them against each other. It also provides a method for levelling a tile.

The prior art of AU patent No. 2014100597 entitled "tile levelling device", granted 7/10/2014, describes a tile levelling device provided with a base having an upper surface and an opposite lower surface. The device includes one or more apertures formed in the top surface. The rod connects the upper surface at a lower point of the cavity or an attachment thereto in a frangible manner. The rod includes a generally rectangular aperture adapted to receive a wedge.

Disclosure of Invention

To solve the problems and limitations of the prior art, we propose a kit for levelling tiles on floors and wallboards, comprising five elements:

the first element is a pulling pliers, the upper jaw of which has a double beak to grip the arch post of the levelling arch when the lower jaw is closed or retracted, the wedge is inserted into the arch from the thinnest part to the thickest part and presses the levelling wedge inside the levelling arch, forming a self-levelling part of the overlapping connection of the arch and the wedge system, so that, when passing through its centre, the crossbar (cross bar) of the arch is lifted and the bases of both are connected to the same horizontal line on which the tile is placed.

The second element is an arch with a flat base, the upper part of which is cruciform, due to the raised ridge (crest) at the centre between the arches of the arch being 1 mm thick and 6 mm high.

The third element is an arch with a flat base and the upper part of the base is a half top ridge of a T1 mm thick and 6 mm high.

The fourth element comprises a wedge reinforcement of larger diameter than the arch with a flat base, with a threaded groove slightly larger than the top of the arch or the top of the crossbar, so that it can be inserted through the threaded groove and work under the wedge by pressing the top wall of most tiles.

The fifth element is an elongated block wedge, which has a flat base that can be pressed down and a stepped top ranging from 1 mm to more than 15 mm, according to the internal dimensions of the arched door and also according to the thickness of the tile to be leveled.

A new tool has been developed relating to the first element, comprising a pulling pliers called "double beak pliers for levelling tiles" (fig. 1), comprising the following elements:

a) the upper clamping jaw comprises three parts:

-the first part comprises, as a double beak, a double tip (1AB) in the shape of an arch provided with two parallel elongated operating columns (1E) to rest against the two arch columns of the arch

-a second part having a threaded groove opening (1D) and a curved embossing groove (1C) so that the lower jaw (1F) reciprocates radially precisely

-an elongated ergonomic third portion with smooth-surfaced extension, to be used as a first portion of the pliers handle, to generate comfortable and quick pressure (1E)

b) The lower jaw comprises three parts:

the first part comprises a toothed tip with a slight curvature (1G) to better grip the rear part of the wedge during retraction

-the second part is provided with radial embossments, movable between the radial embossments of the upper jaw, provided with holes (1J)

To insert the pivoting bolt (1H) so that the two jaws are held together and enable the movement and adjustment of the pressure exerted by the chock on the arch, as well as determining the retracted starting position of the chock with respect to the arch.

-the third part in the elongated ergonomic smooth surface extension acts as a forceps handle (1I)

In order to provide more effective pressure.

c) Through bolt, the head is half square structure for move when the clamping jaw opens to fix when the clamping jaw is closed and avoid moving, and the tip is provided with chamfer and screw thread, with the gasket that cooperates the nut and be located between head and the nut. The bolt can be easily turned without loosening when passing through the nipper parts a and b.

In addition, as noted above, improvements have been made to existing arched doors (2A) which typically have a flat surface on top of the base. When these arches are jacked up for the insertion of the wedges, the tiles are jacked up and held in line, while the improved base is provided with a crest (crest) at its centre (4C) in the shape of a cross for equally separating and holding the top walls (verticals) (7B) of four tiles at a time, while the top (3B) of the arch with a half crest in the middle of the base is in the shape of a T, facilitating equally separating holding three tiles at a time, which greatly reduces the need for the existing arch (2A); finally, a cleat reinforcement (6A) has been developed, which is a rigid flat device with a thread groove of a larger diameter than the arch bar and the base of the arch, in order to distribute the cleat pressure over a larger diameter range for better levelling of the tile from top to bottom.

To make more detailed improvements to arches, arches have been perfected to provide further benefits and to improve the utility of these devices. For example, the base of these arches, which is 3 mm thick, not only lifts the tiles, but also ensures a minimum clearance between the tiles and the floor or wall panel to which they are applied, and a minimum thickness of the base of the arch and a minimum amount of glue or mixture, so that the use of these arches makes it possible to reduce the amount of glue between (floor and tiles). Likewise, we have observed that with the existing arch and chock system, the constructor almost has to use up to eight arches (7A) for every four tiles, which are discarded after levelling, and therefore will place the arches in the corners to save the number of arches, and therefore when the glue is quick-drying or before it dries, remove the levelling instrument without damaging the arches, thus saving one of them. This application will be equipped with middle part horizontal pole (3B) and the arched door (4C) of T shape and apply in arched door and the wedge system, it configures to 6 millimeters height and 1 millimeter thick, not only can be used for jacking the arched door (as jacking and flat ceramic tile corner until the ceramic tile by the horizontal arched door that levels), and in parquet veneer design, to the cross base, be fit for fixing the calibrator at the top center of every four ceramic tiles, to T font base, it is suitable to fix the calibrator at the roof center of every three ceramic tiles, in order to keep four and three roof on a line, prevent that weight from making the corner unevenness, thereby avoid using more levelling instruments through placing the levelling instrument of this application, and set up the wedge reinforcement and improve the function of center arched door and T shape arched door.

Effects of the present application

The technical result is that a new arch and chock device has been developed to improve the work of the constructors around the world, making the alignment of the tiles faster and the results obtained better, which comprises an effective improvement to new tools to lock the chocks against the arch under the action of traction in a faster, simpler and more cost-effective way. A new type of arched door has also been developed, improved in terms of dimensions, main set-up, base thickness, with the aim of better aligning the four tiles when they are joined, in order to apply tiles with a thickness above 3 mm to the floor, and to be able to concentrate the elements separated by a top ridge greater than 6 mm.

The advantages of the proposed invention are even more evident when installing tiles on a flat floor or tiles, since the height of the base of the archway, as a minimum base, is set at each of the four corners of each tile, with a minimum base of the same height of three millimeters and more, allowing anyone to stand on the base when pouring the mixture, all four edges will rest evenly on the height provided by the archway, whatever the weight. Thus, the proposed invention will use less material (i.e., less leveling arches and less glue required) to facilitate and improve work efficiency.

The proposed improvements are fully applicable to previously leveled floor surfaces; it is better if the floor is perfectly aligned before being applied, a new base thickened by 3 mm from the levelling arch will be used as an accurate reference for optimizing the use of glue and the levelling of the tiles, while also eliminating the use of the same levelling devices.

Finally, applying two main changes of applying the middle cross bar and the raised base to the arch makes the top wall of each tile easier to level, thus reducing the use of leveling devices to adequately align the floor and wall panels.

Thus, the present application includes a kit of elements that work together to level tiles placed on floor and wall panels.

The kit includes:

1. a pair of traction pliers for the wedges and arches for levelling tiles

2. Ceramic tile levelling arch

3. Ceramic tile leveling wedge

4. Middle arched door with cross-shaped base

5-middle arch with T-shaped base

6. -cleat reinforcement

The new pulling pliers for levelling tiles have the advantage of relying on a similar working system that is long-standing, such as the parrot beak pliers. With this tool, the opening and closing system of the jaws is powerful and precise; furthermore, it is also possible to make quick adjustments to move the jaws away from or close to the point of connection without having to resort to bolts or other toothed surfaces (many other models of doors built to retract wedges relative to arches).

In addition, ergonomic changes have been made to achieve the desired results in a simpler and faster manner. A new improvement has been proposed for the arched doors of levelling floor and wall panels and the arched doors of cleat kits, where the change is based on three relevant aspects:

first, the tiles are lifted and aligned at the bottom by means of the base of the arch, so as to form a uniform base of thickness 3 mm and above. This new height helps to optimise the amount of glue required for each tile.

Second, the cross-shaped configuration of the central crossbar, separating the four top walls and the T-shaped configuration, facilitates better alignment and fixing of the three top walls, thus facilitating perfect alignment of the corners of the tiles located in the arch. That is to say that eight levelling devices are not required for every four tiles, only five levelling devices are now used, or the need for levelling devices can be reduced by up to 50%.

Third, the wedge reinforcement of the rigid flat device, which has a larger diameter than the base of the archway, wherein the base has threaded grooves or openings slightly larger than the crosspieces of the archway, facilitating the insertion between the archway above the tiles and below the wedges, exerting a uniform pressure over a larger area than that normally occupied by the wedges.

The use or application of the kit is very simple, so that the attachment or covering of floor and wall panels is done twice as well:

traction pliers for rapid and ergonomic clamping of arches and wedges

The arched door has two fins on a base, above which is an arched structure with 1 mm thick studs and rails of uniform thickness to allow the wedge to be inserted between the studs from their smaller side to their larger side, which when in contact with the rails of the arched door cause it to lift the fins upwards during insertion, perfectly aligned with the bottom of the tile.

Block wedges with grooves along the whole top, which can be used as locking means, preventing the wedges from sliding backwards on a crossbar that passes through and is inserted into the arch, and when the downward pressure increases, they will align the tiles as much as possible, so that the tops of the tiles are perfectly aligned.

In order to better understand the working principle of the proposed kit, it is necessary to first understand the limitations of the tile levelling devices leading to the previous prior art; then, the method for solving the leveling problem of the existing tile leveling device is known; finally, it is known how the proposed invention improves the way of use, efficiency and results.

When laying floors and wallboards and when the tiles are too heavy or the poured mix is too much or too little, the laying of the tiles always has the disadvantage of uneven settling. Therefore, it is necessary to always fix the levelling device in position to ensure that each tile laid is subjected to a proper levelling treatment; after one meter, the tile was again inspected. By doing so, we find that where one side of the tile is lower than the other, uneven tiles will have to be repositioned.

When such arch and wedge solutions are developed and used with special pressure applying pulling tongs, and in the case of pressure applied by a particular pulling tong, the parallel forces applied by the wedges from top to bottom and by the arch from bottom to top.

These systems work as follows:

first, the planar arrangement of each tile is placed in the area of the floor or wall panel finish to be applied, and the placement of the first tile is determined.

Secondly, pouring the glue mixture and placing the first ceramic tile. Under each tile, two arches are placed near the corners of each side. At the moment, the leveling instrument is used for manually leveling the glue, and the glue is matched with the existing leveling instrument by 100 percent.

Thirdly, after the arch door is correctly placed on the first ceramic tile, glue mixture is continuously poured into the two ceramic tiles on each side, the second ceramic tile is placed, the corresponding wedge penetrates through the arch door, and when the two ceramic tiles are mutually extruded, the two ceramic tiles are completely aligned at the top and the bottom due to the weight, the gravity or the consistency of the mixture, and any subsequent sinking is avoided.

Fourthly, the next tile is placed together with the corresponding mix, and the wedges are pressed against the arch as each tile has a new mix placed.

Fifthly, removing the arch by striking the arch laterally in the connecting direction with a toe or a rubber mallet after the application or the next day when the glue mixture has dried, so that the arch pillar of the arch is broken at the bottom thereof; they are then removed and the broken arch is discarded while the wedges are retained for later use.

With the new leveler, the constructor will have the advantage of working faster and the floor and wall panels are aligned as flat as a mirror or billiard table.

However, it should be noted that this new method of effectively using the new levelling instrument requires two levelling instruments per side, and eight arches and eight wedges must be used for every four tiles when the arch with the cross bar is not used. Arches correctly using crossbars supported only by one side levelling instrument will obviously require fewer levelling devices and the improved pliers will be simpler and more cost-effective and have fewer parts than the existing pliers, saving money and making the work easier and cheaper.
