Description

MOBILE FORMWORK FOR MAKING Paving Slabs DIRECTLY IN PLACE

The utility model relates to the construction industry, in particular, to formwork for forming paving slabs.

Paving slabs is an important element in creating the landscape of the city and contributes to its ennoblement. However, laying or replacing tiles usually leads to the fact that part of the pedestrian road is blocked for a long time, thereby creating inconvenience to the population.

Known designs of forms (formwork) for laying paving slabs imply the remote production of paving slabs from the place of its laying, loading and unloading operations and laying the tiles on a pre-prepared base, which leads to a significant increase in the cost of coverage (RU 2122058, 11/20/1998). In this case, it is necessary to accurately calculate the amount of tile used, taking into account that part of the batch of tiles during transportation can be damaged or, in the case of recalculation, part of the material used can be wasted, which is generally disadvantageous. In addition, the beauty and longevity of the pavement largely depends on the quality of the laying of the finished tile, compliance with all stages and the nuances of laying, which requires a certain skill and is generally laborious (http://www.strbaza.ru/rekomendatsii-po-ukladke -trotuarnoj-plitki-bruschatki.php)

A known design of a mold with several compartments (RU 2081745, 06/20/1997), including a pallet with racks, longitudinal and end walls, dividing walls, made of two sheets, United between non-molding surfaces and on the sides using plates, the side of which is opposite the end board, beveled from the base of the dividing wall to the end of the plate, while at the ends of the plate towards each other under the pallet and with a gap of relative fingers are installed. For the manufacture of tiles using this form, various additional equipment is used: brackets, clips, screws, hoses.

This form allows you to produce tiles by injection technology and does not require highly qualified personnel. However, when using this form, paving slabs are made in advance, which leads to the above disadvantages. The design of the mold is complex, while for the manufacture of tiles it is necessary to use additional equipment, which creates inconvenience in use and increases the complexity. In addition, when using this design, it is possible to obtain paving slabs with one type of pattern, which limits the possibility of using the form.

A known design of a tooling for the manufacture of tiles (RU 101668, 01/27/2011, RU 2452619, 06/10/2012), which contains a mold with side walls and a bottom, a template that can be installed inside the mold, having dimensions corresponding to internal dimensions side walls of the mold, at least one partition between them to form compartments.

The design of the form is simple and at the same time allows you to make tiles of different colors and with a different pattern specified by the location of the internal partitions. However, in this case, it is possible to produce tiles only remotely from the installation site, which leads to costs for loading and unloading, wasteful use of time and possible waste.

To eliminate these shortcomings, it is possible to use form designs (formwork), which allow the production of paving slabs directly at the place of its laying.

The construction of the formwork is known (RF patent No. 2122058, 11/20/1998), adopted as the closest solution to the claimed one, containing a rectangular frame of metal profile, the cross section of which is divided by vertical partitions from sheet steel into cells, the cross-sectional shape of which corresponds to the shape of the cross cross-sections of cobblestone elements, while the partitions should intersect at right angles, the permissible placement of transverse compression joints can be at an angle of 78-80 ° to the longitudinal axis of the pavement.

This design of the formwork allows you to produce paving elements directly at the place where replacement of worn or destroyed sections of pavement is necessary, which is convenient, saves money, reduces labor intensity due to the lack of the need for loading and unloading operations. However, this formwork design is a prefabricated metal product, the shape of which cannot be changed during operation. That is, using this formwork, it is possible to obtain block-shaped elements having the shape of a prism, the basis of which is one of the figures: a square, or a rectangle, or a rhombus. If it is necessary to obtain block-shaped elements of different shapes, it is necessary to use several types of this formwork with different shapes of cells inside it. In addition, the formwork frame is a rigid structure of a rectangular shape, which remains unchanged when the shape of the cells inside it changes. Thus, the considered formwork design has limited functionality.

The technical result of the utility model is the ability to obtain different types of patterns of paving slabs using only one tool - the expansion of functionality when using formwork.

The technical result is achieved by using formwork for the manufacture of paving slabs directly at the site, which contains plates forming the outer formwork frame and connected to the polygon by means of connecting elements that allow axial displacement of the plates forming the external formwork frame, additional partition walls with protrusions that are installed into incisions made in the plates forming the outer frame of the formwork, with the cells inside the polygon.

The presence of individual plates forming the outer casing of the formwork and connected to a polygon, the use of connecting elements with the possibility of axial displacement of these individual plates, the presence of additional inserts with protrusions that are installed in the cuts in these plates to obtain cells inside the polygon, allow disassembly-assembly of the structure formwork into parts to obtain the necessary type of polygon and fixing the plates and inserts in the desired position. Thus, due to the displacement of individual plates in any direction and the use of additional inserts, several different types of formwork polygons can be obtained from one type of formwork polygon at will. As a result, it is possible to obtain a simple and universal design of formwork for the manufacture of paving slabs directly at the place of its laying, which allows you to get different types of patterns of paving slabs and thereby expand its functionality. At the same time, the ongoing operations for the production of paving slabs do not require high accuracy and skill, so the quality of work can be obtained with the involvement of low-skilled personnel.

The plates forming the external formwork frame, and additional insert-partitions can be made of metal, wood, plastic and other material.

The cells inside the polygon formed by using additional inserts can be, for example, an equilateral triangle, square, rhombus, rectangle and other more complex shapes, which also contributes to the receipt of different types of patterns of paving slabs.

As elements of the connection of the plates, allowing them to produce axial displacement, canopies can be used.

The individual plates forming the outer formwork frame can be assembled into a polygon, which is, for example, a square, a rectangle, a parallelogram, a rhombus.

The polygon defining the outer frame of the formwork structure can be duplicated in any direction using similar additional blocks.

The plates forming the outer formwork frame have plates with a point pointed downwards, which during assembly allow fixing the structure at the installation site. Plates with a tip can be made of metal, wood, plastic and other material.

In FIG. 1 shows a general view of the movable formwork without displacement, in FIG. 2 shows a view of a movable formwork after axial displacement.

The movable formwork for the manufacture of paving slabs directly in place contains plates 1 forming an external formwork frame and joined into a polygon by means of connection elements 2 (for example, door canopies), which allow axial displacement of the plates 1 forming the external formwork frame, additional partition walls 3 s protrusions that are installed in the incisions 4 made in the plates 1, forming the outer frame of the formwork, with obtaining sectors within the polygon. Also, the plates forming the outer frame of the formwork, have plates with a pointed tip 5, which allow fixing the formwork at the place of its installation.

The manufacture of paving slabs using the claimed design is as follows. Directly at the installation site, the site is initially prepared: a sand cushion is prepared, which is abundantly watered with water. Further (see Fig. 1), the plates 1 forming the outer frame of the formwork are laid in the shape of a polygon (for example, a square, a rectangle, a rhombus, a parallelepiped) and fastened to each other by means of, for example, door canopies 2. By means of plates with a tip pointed downwards 5, the outer frame is fixed on a sand cushion. In the plates 1 forming the outer formwork frame, notches 4 can be made in advance or directly in place, into which additional insert-partitions 3 having protrusions are inserted in different directions. The protrusions of the additional insertion partitions 3 can be made in advance so that two such insertion partitions 3 are placed in one incision. For example, it is possible to perform protrusions with different indents from the edges of the additional insertion partitions 3.

If necessary, changes in the external shape or obtaining a different shape of the cells make the following changes to the same formwork design: by means of connection elements 2, for example, door canopies, the axis of the plates 1 forming the outer formwork frame is adjusted, shifting them to the desired side, and a new necessary type of polygon is obtained (Fig. 2). In the cuts 4 of the plates 1, additional insert-partitions 3 are installed to obtain a new original type of formwork. For example, to obtain equilateral triangles inside the polygon, the original polygon is shifted until a parallelogram is obtained, additional insert-partitions 3 are used, the length of which is equal to the short side of the parallelogram, along the long side of the parallelogram at a distance equal to the length of the additional insert-partition 3, cuts 4 are made into which with the formation of triangles, additional insert-partitions are installed 3. The formed frame of the formwork design can be duplicated in any m direction by the addition of similar units. Further, after installing the formwork in the required position, the structure is poured with concrete or other similar material. Then, after the concrete has hardened, the elements of compound 2, for example, door canopies, are removed from the structural parts, additional insert-partitions 3 are removed. The outer surface of the resulting tile is decorated, for example, with natural stone, broken glass, prints on the surface of the formwork aggregate, followed by concrete filling using a color caller, and is also decorated with mosaic patterns from suitable materials that can withstand outdoor operating conditions and loads. Also, some household waste can be used to finish the surface of paving slabs, for example, broken or cut glass, plastic, which indicates an increase in the environmental friendliness of the solution and additional economic benefit when using it.

Partition inserts can be metal plates with a thickness of 3 mm, a length of 60 cm (without protrusions) and a height of 7 cm, which are installed in cuts 3.5 cm deep, made in plates 180 cm long, 7 cm high, 3 mm thick. Moreover, the height of the protrusions of the additional insert-partitions is 17 mm.

Using the construction of the formwork allows you to bypass the third-party process of production of paving slabs, its transportation to the destination, which allows you to save up to 50 percent of the costs and reduce the complexity. Also in this case, there is no need to make initial calculations of the required amount of finished tile, after which waste may remain. Concrete or other pouring material at any time, if necessary, can be made in the required quantity. Moreover, the construction of the formwork is simple and reliable, its use does not require the use of highly qualified personnel, it can significantly save time on laying paving slabs and carrying out repair work.

Thus, the design of the claimed formwork is universal - due to the displacement and fixing of individual plates of the same design in any position, it is possible to obtain several types of formwork with a different pattern, which extends the functionality of its use.

As a result, the decoration of the landscape of the city and its ennobling become more convenient and economical.
