METHOD AND APPARATUS FOR MAKING A SENSOR MOLD

FÖRFARANDE OOH ANORDNING FÖR UTFORMNING AV FORM FÖR GRUNDPLATTA 5

TECHNICAL FIELD OF THE INVENTION

The invention relates to a method and apparatus for forming a probe mold as disclosed in the preamble of the independent claims below.

BACKGROUND OF THE INVENTION

The antura is usually the lowest part of the foundation, which distributes the weight of the building over a wide area.

15

The sensors are generally made of reinforced reinforced concrete. Sensor molds are made of, for example, wood, especially boards. Building molds from boards is slow and it is difficult to recycle boards as they are difficult to clean after use. It is also difficult to dismantle the mold without breaking the boards and sawing and dimensioning the used boards in new use.

The Finnish utility model publication U20060265 discloses a casting mold with a wall made of metal sheet. The wall piece comprises holes for securing the bonding structures. According to the figures disclosed in the publication and another main idea of the invention, it appears that the wall pieces are intended to be left in the molded part of the structure, and therefore new molds are required for each casting.

US Patent No. 2,661,517 discloses a concrete mold comprising telescopically arranged inner and outer parts for forming a mold wall. Each part has a vertical wall and a top and bottom edge perpendicular to it. There are holes and gaps in the upper and lower edges through which vertical bars are provided for securing the parts to each other and securing them to the ground. The two different walls of the mold are joined together by means of wire or rod-shaped cross-members which are attached to vertical bars. Using the solution can be problematic if the soil is hard or for some reason it is difficult to fix a vertical bar. It should be possible to determine an appropriate distance between the vertical bars 5 and thus the walls before fixing the bar to the ground. This requires the aforementioned crossbar or other distance aid.

Also, in the solution disclosed in US 4,121,804, the casting mold parts are telescopically arranged and fixed to the ground by means of vertical bars. The solution is similar to that of US 2,661,517, but US 4,121,804 does not disclose the attachment of two parallel mold walls.

15 One problem with the disclosed solutions is that the finished holes or gaps used therein can be easily blocked and the pins, rods or similar fastening means provided therein may be twisted or lost, or easily adhered to the concrete mass, after which they will be difficult to remove from the holes or re-fit the holes. The distances between the holes are predetermined, so that the length adjustment possibilities of the mold 20 to be formed are stepwise.

PURPOSE AND DESCRIPTION OF THE INVENTION

The object of the present invention is to reduce or even eliminate the above-mentioned problems of the prior art.

? In particular, it is an object of the present invention to provide a solution in which the mounting of the side walls of the sensor mold is easier than in known solutions.

C/O

It is an object of the present invention to provide a solution in which the side walls are ........

can be securely fixed without having to be fixed to the ground by means of a rod or similar fastening device.

The object of the present invention is to provide a solution in which the two side wall pieces intended for the side mold walls of the probe mold can be placed at a proper distance from one another without having to measure or determine the distance between them during installation.

It is also an object of the present invention to provide a solution in which the length of the probe mold wall can be infinitely adjusted.

Among other things, to accomplish the above purposes, the method and apparatus for forming a probe mold according to the invention is characterized in what is stated in the characterizing parts of the appended independent claims.

The application examples mentioned in this text apply, mutatis mutandis, to the inventive method as well as to the apparatus, although not always specifically mentioned.

In a typical method of forming a probe mold according to the invention, 20 - positioning the lower connecting pieces to the ground, - placing the first side wall pieces in contact with the lower connecting pieces so that the inner surface of the first side wall pieces adjusting the length of the first wall of the transducer and thereby forming the first wall of the transducer mold, one side o defining, and the majority of the other side wall pieces being telescopically inserted within each other and The second wall of the probe mold thus formed is adjusted to a suitable length.

4

In the method, the first side wall pieces are fitted to a first support shape in the lower connecting pieces, and the second side wall pieces are fitted to the second support form at a distance from the first support form so that the first and second side wall pieces are secured

A typical apparatus for forming a transducer mold according to the invention comprises at least 10 - first side wall portions whose inner surface can be arranged substantially vertical and delimiting the first side of the moldable transducer, and the first side wall portions second side wall pieces having an inner surface that can be arranged substantially vertical and defining one side of the die cast, and the other side wall pieces being telescopically adjustable to one another extending so that the second wall of the probe mold to be formed is adjustable;

The lower connecting pieces comprise: - a first support shape to which the first sidewall member is adaptable and? distance between them.

° 30

O

The apparatus according to the invention may also be referred to as means for forming a mold.

5

An advantage of the invention is that the sidewalls can be easily fixed in place in connection with the support form of the lower connecting pieces without the need to attach the sidewalls to the ground or to other parts of the sensor mold, for example. The support forms, without the need for any other support or fastening means 5, are arranged to hold the wall pieces firmly upright.

An advantage of the invention is that the two side wall pieces intended for the side mold walls of the probe mold can be easily and quickly placed at the correct distance from one another without having to measure or determine the distance between them during installation. The distance between the lower connecting piece and the distance between the support forms determines the distance between the side wall pieces.

According to one embodiment of the invention, the sidewall members are substantially C-shaped, comprising 15 - a vertical wall portion, the inner surface of which is intended to be arranged against a detachable transducer, - a continuation of the vertical wall portion extending vertically 90 degrees and vertically intended to be directed perpendicularly away from the molded mandrel, and - vertical limbs bent at an angle of substantially 90 degrees to each other, extending from and to the upper and lower portions.

Molded transducer means a transverse transverse transverse transverse transverse transverse transverse transverse transverse transducer, e.g.

O

^ The C profile profile of the side wall pieces is intended to be open to the sides and away from the sensor to be selected.

LO

According to one embodiment of the invention, the support forms of the connecting pieces are substantially U-shaped, comprising two vertical leg portions and a horizontal base portion connecting them.

6

According to one embodiment of the invention, upper connecting pieces are positioned adjacent to the top of the side wall pieces so that the top of the first side wall piece is seated in the first support shape in the top connector and the top of the second side wall member in the top connector.

According to one embodiment of the invention, the upper and lower connecting pieces are identical. The same connecting piece can then be used either as a lower connecting piece, whereby the U-profile shaped supports are arranged upwards 10, or as an upper connecting piece, where the U-profile shaped supports are arranged downwards. The identical top and bottom connecting pieces are thus arranged upside-down relative to one another when forming the sensor mold.

By telescopically inserting the side wall pieces into one another is meant extending part of one another into one another and the longitudinal extension of the wall formed therefrom. In one preferred embodiment, the side wall pieces are of two different sizes such that each other piece is telescopically arranged outside the former and every other piece inside the former.

20

According to one embodiment of the invention, the end, and preferably the corners, of the outer, i.e. larger C-shaped, side wall piece are removed so that the inner side wall portion is more readily positioned against the vertical wall portion of the outer side wall portion and then telescopically . For the same purpose, the ends of the side wall piece may be cut obliquely, e.g. at an angle of about 45 degrees, with respect to the vertical wall portion. For the same purpose, in one embodiment, the light top and bottom portions of the sidewall piece and the vertical leg portions bent therewith toward each other are removed, e.g., at a distance of 1 to 5 cm from the end edges of the sidewall piece.

7

The first and second side wall pieces may be identical to each other. The height of the side wall pieces can be, for example, 200 - 500 mm.

In the method, the inner surfaces of the side wall pieces are generally arranged at a distance of about 200 mm to about 5,600 mm. This distance corresponds to the width of the probe to be cast. The distance can also be e.g. 200 - 1000 mm or 200 - 3000 mm.

According to one embodiment of the invention, the method further provides central connecting pieces between the inner surfaces of the side wall pieces. Generally, the mid-10 acceleration pieces are arranged at a height between the lower and upper connecting pieces. Preferably, the central connecting piece is similar to an upper and / or lower connecting piece, but has, at its ends, e.g.

According to one embodiment of the invention, the side wall pieces and the connecting pieces 15 are formed of a thin sheet having a thickness of not more than 4 mm, preferably 0.4 to 3 mm, very preferably 1 to 1.5 mm. In this application, thin sheet refers to a sheet of metal having a thickness of up to 4 mm.

The sheet metal material may be, for example, galvanized steel or aluminum. Other metals or materials may also be used. The sidewalls and connecting pieces may also be e.g. plastic, carbon fiber or fiberglass.

The top and bottom link is commonly referred to as the link, unless you want to explicitly mention which one.

Preferably, in the method, the connecting pieces are used as a rack for reinforcement. The connecting pieces may have notches to hold the reinforcement in place. Holes may be provided in the frame between the support forms of the connecting pieces.

Already, Reiki can be used to bind reinforcement. Preferably, the holes are also left free so that the concrete mass of the cast can fill the hole, whereby

O

«M is firmly attached to the concrete mass and the casting strengthens considerably. This can even replace some of the steel reinforcements.

8

The connecting pieces may have an edge between the support forms, which makes the connecting piece more rigid. The first edge of the body portion of the connecting piece can be provided with an upward edge and the second edge with an edge downward. In this case, a similar connecting piece is well suited for use as either an upper 5 or a lower connecting piece.

According to one embodiment, the length of the connecting pieces is adjustable. This can be accomplished, for example, by a telescopic or other sliding structure of the connecting piece.

10

One simple top connecting piece is U-shaped such that its first leg is disposed outside the first side wall piece and the second leg is disposed outside the second side wall piece. The base of the U-profile connecting the first and second legs extends from the first en-15 side wall piece to the other and thus joins them.

According to one embodiment of the invention, the length of the sensor mold walls is infinitely adjustable. In this embodiment, according to known solutions, telescopically arranged side wall pieces do not require pre-formed staggered holes, which should be aligned and through which a pin or rod member should be provided to lock the length of the wall. Preferably, therefore, the apparatus lacks means for stepwise adjusting the length of the walls.

In addition to being easy to assemble, the sensor mold of the invention is also very easy to disassemble and clean, and therefore its parts, especially the side wall pieces, can be reused tens, even hundreds of times. Advantageously, the side walls of the sensor mold according to the invention are to be removed from the finished mold 5, but they can also be left in the mold. Usually, the connecting pieces remain inside the casting.

Preferably, the edges and corners of the connecting pieces and side wall pieces are rounded to remove sharpness so that they do not cause cuts in hands or gloves when processed.

According to a preferred embodiment of the invention, the connecting pieces can be attached to the side wall pieces by means of drill screws. If necessary, the first side wall pieces can also be attached to one another, and the second to each other, respectively, by means of drill screws. The advantage of drill screws is e.g. cheap price and easy attachment and removal. Also pop rivets, welding, press fittings can be used.
