Abstract

The spacing tool consists of a cylindrical body (1A) with a notch (1B) at its lower end to engage with a nailed batten, and an adjacent threaded section (1C) for a locking ring (2) to hold it in place. The upper end of the body has a recess (1E) with a shoulder (1E1) to give the position of the next batten to be fixed. The notch measures 50 mm long by 17,5 mm deep, and the recess is 40 mm long by 17.5 mm deep. A hole near the upper end recess receives the end (3A) of a bar (3) used on roofs with valleys and forming a right angle with the body.

Description

The present invention is a manual device intended for

  roofers for the realization or repair of roofs.

  This tool is specifically made for the installation of steel tiles whose particularity of this type of tile concerns its fixing which is carried out by its upper and lower ends and below the slats as opposed to the other tiles which are installed are fixed in part high and above

slats.

  This steel tile requires very precise preparation of

  tracks to ensure its correct positioning on the battens.

  This device is a tool whose dimensions are adapted to the gauge of the steel tile to be laid, in the present case and by way of example the prototype produced corresponds to a tile

with a gauge of 36.8 cm.

  This type of tile requires a regular interval taken from below to below the battens and strictly observed for

  secure the tiles on these battens.

  Currently the means used and available to carry out this operation of tragging the battens are the pencil,

the meter, the compass and the line.

  However despite these tools and all the vigilance of the operator there inevitably occurs during the tragedies a variation of a few millimeters of these traces which results in a bad positioning of the battens which no longer allows the placement of steel tiles which require precise spaces to be positioned and fixed correctly. The causes of these bad traces are various for example: _ a line of cord deviated from its axis due to a bad positioning of the roofer's hand relative to the horizontal axis represented by the wire _ an imprecision of the pencil line from to improper positioning of the meter _ structural deformation of the frame which causes larger spaces in the area concerned

  _ a lack of attention from the roofer.

  Failure to comply with this implementation will quickly reveal after the installation of some rows of tiles that disassembly of the badly fixed battens is essential, which induces

  a waste of time and extra work.

  To date, apart from the aforementioned equipment, there is no device or tool allowing precise positioning of the battens (measurement below / below the battens) for the

  placement of steel tiles on the roof.

  In this context, the invention provides a solution to this type of problem which is on the one hand the suppression of the tragedy of the roof with the exception of the first batten which is the starting batten and on the other hand the suppression of all the consequences due to poor stage fright, age (loss of time, etc.) The present invention is a tool calibrated to the dimensions of each steel tile (by way of example but not limiting,

  in this case the gauge is 36.8 cm).

  It guarantees regular intervals between the battens.

  This invention has other advantages which are: the simplicity of use an installation as well as a rapid withdrawal of the device on the battens an ergonomics adapted to the use of the roofers (its advantages will be explained in the chapter relating to the use of the tool) _ Improved security; (suppression of displacements on the roof which proved essential to carry out the tragedy of the positioning of the battens) The tool, in this case is machined from aluminum but it can also be manufactured with other materials such as

  plastics either injected or machined for example.

  According to a preferred form, this tool has a cylindrical and tubular shape, the advantage of which is that it has no projecting edges, which limits any risk of injury to the user. The invention and the advantages which it brings will be better understood thanks to the example of embodiment given below by way of indication but not limitation which is illustrated by the appended drawings: _ Figure N 1 represents in front view the assembly of the device in the rest position with its angle transfer rod _ figure N 2 represents the tool body in profile view _ figure N 3 represents the clamping ring of the cylinder body _ figure N 4 represents the angle transfer rod in front view and in vertical position _ figure n 5 represents the tool in working position positioned on the battens _ figure n 6 represents the tool provided with its angle transfer rod positioned on the battens of a roof with a valley Valley = meeting of 2 sections of the roof)

DESCRIPTION OF THE DEVICE

  This device is made specifically to facilitate and

ensure the laying of steel tiles.

  I1 consists of a body (1) of cylindrical and tubular shape, a clamping ring (2) and a rod (3)

removable angle transfer.

  THE BODY OF THE APPARATUS (1) (see drawing N 2 I1 consists of a cylindrical tube (1A) whose dimensions by way of example but not limitation are of

  420 mm in length and an outside diameter of 35 mm.

  The length of this body corresponds to a tile-steel model

with a gauge of 368 mm.

  Its lower part was the subject of 2 machining operations represented by a notch (1B) and a thread (1C) with a length of 135 mm with a step to the left made on the external face ending at a centimeter from the edge of the device to prevent the clamping ring from coming out of the device body. Its upper part was also the subject of 2 machining operations represented by a hole (1D) with a diameter of 6 mm passing through the tube to allow the positioning of the angle transfer rod (3) and a notch (1E) with a length

  40 mm and a depth of 17.5 mm.

  The lower part of the body: The notch (1B): It has a length of 50 mm, a depth of 17.5 mm and

  located 10 mm from the end of the body.

  This notch has the functions of positioning and fixing the device on the strip already nailed after tightening the ring which allows to obtain the calibration of the

  device for placing the next strip.

The filetane (1C):

  It has a length of 135 mm and its pitch is on the left.

  It consists of 8 threads, the advantage of which is to allow rapid movement of the clamping ring on the body of the device. In addition, this choice of left-hand thread allows during the installation of the device on the batten an easy movement of the rotation of the hand from the outside towards the inside at the time of the tightening of the ring until its locking while exerting, ant on the device a pressure in order to correctly position

this one on its support.

  The upper part of the body: The piercing (1D): With a diameter of 6 mm, passing right through the tube slightly offset (machining side) relative to the horizontal axis of the body, it is positioned so as to align the underside of the shoulder (1 E1) with the outer face of the angle transfer rod (3) when it is placed either on the right side or on the

  left side of the camera body.

  The shoulder 1 E): The machining of this shoulder is positioned according to the

length of tile-steel to be laid.

  In the present case by way of example, the lower face (1 E 1) thereof is located at a distance of 368 mm from the lower face of the notch (lB1) situated in part

bottom of the camera body.

THE RING (2)

  Its dimensions are 80 mm in length and an outside diameter of 40 mm. Its internal face (2A) has a thread whose characteristics are identical to those produced on the body of the device.

( 1 C).

  Its external face (2B) is knurled to ensure good grip of the device during the tightening and

loosening of said ring.

THE ANGLE ROD (3)

  Cylindrical in shape, for example it has a length

  total of 180 mm and a diameter of 12 mm.

  One of its ends has a shoulder (3 A) of 30 mm in length and a diameter which is logically less than the hole made on the body of the device (1 D) to allow its

  positioning on the tool body.

ARRANGEMENT OF THE DEVICE

  This tool is arranged as follows: The clamping ring (2) is placed on the body of the tool and held in place by means of the threads.

the appliance (1 C / 2 A).

  During work to be carried out on roofs with a valley: This device is temporarily equipped with its transfer rod

corner (3).

  USE OF THE DEVICE (See drawing N 5) 1st case: Realization of a roof without valley At the beginning of the works it is necessary to trace only the positioning of the starting batten with traditional means, the stage, age finished and said batten nailed, only this device will be used during the work. After nailing the first strip, the device is positioned on the strip at the lower notch (1B) of the body of the device, then the opening of the ring is adjusted according to the section of the strips used in order to '' block it on the batten with a quarter-turn rotational movement of the hand, which allows placement

device.

  Once the ring has been adjusted, the device is fixed to the batten after blocking the ring, then the nailed batten is taken, which is brought into abutment in the shoulder (1 E1) of the upper part of the tool by holding it manually during the nailing operation, this being completed, the clamping ring of the device is released by performing a reverse rotation movement of

  hand to free the device from the batten.

  These operations must be repeated at each crossing of

  chevron for all battens to be laid until the ridge.

  This tool is calibrated to the dimensions of the steel tile to be laid. I1 guarantees regular and precise intervals as well

  that an easy installation of these materials without loss of time.

  2nd case: Realization of a roof with valley (See drawing N 6) Regarding the start of works this is identical to the previous chapter (tracing of the positioning

  of the starting strip with traditional methods).

  The installation of the starting batten being finished, the angle transfer rod (3) should be placed on the device to determine the correct positioning of the batting to be placed on the valley of the valley because it is not on the same alignment as the lower batten must be from the start parallel to the previous batten in order to maintain a regular interval over its entire length and dimension

  corresponding to the gauge of the tile to be laid.

  The device blocked on the first batten and adjoining the valley constitutes with its angle transfer rod a 90 ° angle which allows to align and guide the batten to be nailed on the chevron of the valley while maintaining a parallelism

with the lower strip.

  Apart from the nailing operations to be carried out in the valley, it is not necessary to leave the angle transfer rod

on the body of the device.

  INDUSTRIAL APPLICATION OF THE DEVICE

  This tool is intended for roofers allowing them to install

easily the steel tiles.

  It will be distributed through a network of specialized stores.
