Description

Gable pin.

 The present invention relates to a device making it possible to establish the measurements that a gable wall must make before its construction, taking as a reference base, the upper part of one of the walls of a building under construction.

 Traditionally, before the implementation of a murpignon, site personnel use makeshift materials, such as bastings, rafters, battens, etc ... with which a nail is planted to hang the cord which will profile in the space, the crawlers of the future gable wall.

 These makeshift elements are generally fixed in their lower part by transverse clamps for maintenance, and by their weight or their flexibility, depending on the cases used, their uncertain and painful handling, does not guarantee any precision as to the dimensions to which the future murpignon will have to correspond, because of the instability of these so-called measuring devices generally made of wood and subjected to the vagaries of bad weather, such as rain, wind, cold, or heat, making work these materials, and moreover, the time spent for their installation and disassembly, after completion of the gable wall, cannot be predicted, the duration of which often greatly exceeds the planning forecasts.

 The present invention proposes to remedy these drawbacks, and to do this, it has for its object, a device which can define the measures which the future gable wall will have to do, in a rational and rigorous manner, carried out in one time. record; characterized by a telescopic system comprising several rectilinear tubular elements A, B and C sliding one inside the other, allowing height adjustment. At the top of the present device, ie at the head of the rectilinear tubular element C, there is provided a hook I0, intended for the cord V, responsible for profiling in space the crawlers of the future gable wall; a metric graduation I3 with direct reading, also appears on one of the faces of said element C, over the entire length of the latter.

 In the lower part, the rectilinear tubular element A or sheath, comprises various pieces of equipment allowing the rapid installation and fixing of the device according to the invention, on the upper part of one of the walls of a frame is in construction ; thanks to VII through-type clamps, called retaining clips, commonly used in the building industry.

The gable walls can therefore now be built in a safe and rapid manner, due to the new design of the device according to the invention and its installation. This is easily achievable, since it will be enough to adjust the height of the straight and telescopic tubular elements
B and C sliding one inside the other, in order to adapt the future gable wall to be produced, to the particular dimensions defined by this device, thanks to its direct metric reading I3.

The embodiment of this invention, described below by way of example, is in no way limiting, with reference to the drawings appended hereto, in which
On board I / 3; Figure I is a schematic perspective view showing the device in its closed and locked phase, before or after its use.

 On board 2/3, Figure 2 is a schematic perspective view, showing the device deployed and put in place for use, on the building under construction.

 On board 3/3, Figure 3 is a detailed view, showing the exploded view of the device in perspective, with the numbered presentation from I to I5 of each of its components.

 The building under construction which can be seen on plate 2/3, in FIG. 2, comprises two parallel walls I and II, interconnected, at one of their ends, by a transverse wall III for connection, support of the future gable wall to be implemented, which will be triangular in shape.

 The different walls I, II and III, constituting this building, are produced in a conventional manner, for example, from bricks or concrete blocks, or even stone, surrounded by a chain of reinforced concrete IV, resting on said walls I , II and III, which conventionally constitutes the upper belt of this battisse. It is the same, when the structure includes a wooden or concrete floor.

In the example shown in the drawing in FIG. 2 on board 2/3, the device has been put in place to determine the height of the future gable wall, as well as the creeping profiles of the latter, using the cord V, stretched thanks to two weights VI, pieces of concrete blocks or others, forming ballast, attached to the ends of this said line V, and hanging on each side either at the right of the angles forming the junction of the walls
I and II with wall III.

It will also be noted that the device is securely held at the head of the connecting wall 111 thanks to the through joint clamps VII, for holding; the verticality of the assembly of the present device being ensured by a spirit level
I4, placed for this purpose in the holding handles 3, forming part of the apparatus.

 The material of which the device according to the invention is made, is mainly metallic, but could possibly be made of any other sufficiently resistant material such as resins, fiberglass and the like, of appropriate sections, including the profiles constituting the main structure of the device whose is question, can be other than tubular.

 In accordance with the invention, the device comprises several rectilinear tubular elements A, B and C, sliding one inside the other, each equipped with various accessories described below.

The straight tubular element A: or sheath A, has several pieces of equipment such as
Two UI-shaped seat elements, each welded in the lower part on each of the side faces, with a sufficient offset to receive the head or the valet of the through-clamps VII, giving all the efficiency of the holding and tightening of these on wall III.

A seat or rest plate 2, welded horizontally on one of the faces contiguous to those on which the seat elements t appear in the shape of a U, this so-called rest plate 2, makes it possible to seat the whole of the device, on the upper part of the connecting wall III, of the building under construction, during the time of fixing the said through clamps
VII, thus relieving the effort of the user.

 Two grip or holding handles 3, in one piece welded to the face opposite to that on which the rest plate 2 appears, on the mounting side of the future masonry of the gable wall. These said handles 3 having the purpose, on the one hand, of keeping the device in the vertical position during its installation and its fixing, and of transporting it in its closed phase, on the other hand.

 A spirit level I4, ensuring perfect verticality of the device, this spirit level I4, is fixed horizontally by gluing or screwing, on a plate 4 forming a base, and protected by a round iron 5 folded at right angles, the whole welded inside the holding handle 3, in the upper part of the latter, being integral with the lateral face of the present rectilinear tubular element A or sheath A.

 At the head of this sheath A, a needle screw 6 appears, having to ensure tightening or loosening on demand, by virtue of a threaded washer or nut 7 welded to the right of a hole 8, this assembly having the purpose of assuming the blocking or unblocking of the straight tubular element B, the latter sliding directly in this said sheath A.

 The rectilinear tubular element B; directly sliding in the rectilinear tubular element or sheath A, is provided in its upper part bordering its waxing, with a needle screw 6, screwing or unscrewing in a washer or threaded nut 7, welded in line with a hole ô, this assembly being quite similar to that existing on the sheath A, and having the same functions, namely blocking or unblocking on request the third and last straight tubular element C, directly sliding in the present rectilinear tubular element B, which has approximately 2/3 of its height a small stop block 9, welded on the face opposite to that on the side where the implementation of the future gable wall will be built. the base of this element B in question, is fixed by screwing, a stud or bolt II assembly with head and washer or threaded nut I2, of which said bolt II passes right through the lower part of said tubula element ire rectilinear B, through the holes 8 provided for this purpose.

 Note that the purpose of the stop block 9, located approximately 2/3 the height of this element B, is to automatically stop the straight tubular element or sheath A, the latter abutting it, at the time of neutralization of the entire device, when it is in its retracted phase, as it occurs before or after its use, on the board I / 3, in Figure I. The said wedge stop 9 located just at the precise point of balance of the device with respect to the holding handle 3, thus avoiding a plunging movement towards the ground, from one or the other of its ends, during its transport carried out like that of a suitcase, offering more convenience to the user.

 As for the bolt II and nut I2 assembly, appearing at the base of the present rectilinear tubular element B; it aims, and in all cases, to avoid the sheath A, to go out, but has the appreciable advantage of a possibility of dismantling the entire device according to the invention, namely, releasing the said sheath A, and as regards the last straight tubular element C, it can slide out of said element B, and this, from the top of the latter.

 The rectilinear tubular element C: directly sliding in the rectilinear tubular element B, has at its extreme upper part, a stop block 9, similar to that existing at 2/3 the height of the element B, also welded on the face opposite to that which is on the side where the masonry of the future gable wall will be mounted, this so-called stop block 9 having the aim of preventing the present element C from sinking further into said element B, at the time of the total closure of the device after its use, and also protecting the hook IO, which could undergo an impact caused by the upper end piece of this element B. This so-called IO hook, cord grip V, is welded to the fact of this rectilinear tubular element C, on the side facing the future masonry which will constitute the said gable wall.

Metric graduations appear over the entire length of said straight tubular element C, and on the side face contiguous to that on the masonry side of the future gable wall
I3, directly entered using a self-adhesive or riveted tape measure, as the case may be; possibly these so-called metric graduations I3, could be engraved by the sandblasting process.

 The ridge of this element C is equipped with a plastic plug I5, of protection, pressed in, having the purpose of preventing the introduction of foreign bodies inside the device according to the invention, such as cement , plaster, earth or others.

 Process for setting up, adjusting and fixing the device for measuring the dimensions of a gable wall, such as a gable rod: to determine the measurements of a future gable wall, of triangular shape, at the Using the device according to the invention, the procedure is as follows: using the grip or holding handles 3, the whole of the device is presented in its closed and locked phase, in a position vertical, so as to rest the rest plate 2 on the waxing of the connecting wall III, exterior side, in order to relieve the user for the various handling operations to come.

 This first maneuver accomplished, the entire device will be oriented as vertically as possible, which will be easily obtained, thanks to the assistance of the bubble level I4, a precious aid for the search for optimum verticality. During these preliminary installation operations, the present device will be attached, on the extramural side and to the upper part of the connecting wall III, of the building under construction, using the through-clamps VII, support, whose head or valet will be received on the one hand, in the U-shaped seat elements, and on the other hand on wooden wedges VIII, placed intra-muros side of said connecting wall III these so-called wedges VIII, which must, of course, receive the head or the valet of these retaining clamps VII, according to the direction chosen by the user. This being, the final fixing of the entire device, by means of the said clamps VII, can be carried out using the hammer, which will have the effect of ensuring a very high clamping efficiency of the assembly, it will have been well taken care of beforehand, of the perfect verticality of the device, obtained by the spirit level I4, housed in the holding handles 3. Once all these simultaneous combinations of vertical positioning and fixing have been carried out, the cord V will be hung on the hook IO existing at the head of the straight tubular element C, this hook IO is finding it within easy reach of the user, as long as the device in accordance with the invention is not in its deployed phase in order to be operational, the design of this device being that '. all the height adjustment operations are carried out as easily as possible, the tightening or loosening apparatus represented by the needle screws 6 being directly accessible to the user, in order to avoid the latter having to resort to which conch utensil or auxiliary tool.

 From now on, the device can be adjusted in height, and to do this, it is sufficient to loosen the needle screw 6, namely, that which is at the head of the rectilinear tubular element B, thus releasing the tubular element rectilinear C directly sliding in said element B, then we pull vertically upwards, this element C by bringing it to the desired metric gradation I3, thanks to its direct reading, this corresponding to the dimension of the future gable wall Once this has been achieved, the present straight tubular element C can be blocked, by means of this needle screw 6.

As for the complete completion of the height adjustment of the device, it suffices to loosen the second needle screw 6 quite similar to the previous one, this second needle screw 6 appearing at the head of the straight tubular element or sheath A, the latter totally neutralized on the connecting wall
III; this last loosening operation consists in releasing the straight tubular element B, sliding directly in this said sheath A, and pulling it vertically upwards until the assembly of bolt II and threaded nut I2, fixed to its base , abuts against the lower end of the present sheath A; this last result obtained, we can tighten this second needle screw 6; let us not forget to specify that in this last maneuver, the rectilinear tubular element B, pulled vertically upwards, systematically carries with it, the rectilinear tubular element C, the latter being integral with this said element B, given the blocking of the first needle screw 6, joining all of these two sliding elements
B and C. This has the resulting effect of infallibly obtaining the real and final height of the future gable wall to be produced.

These various operations completed, after a final verification of principle, we will tension the cord
V, corresponding to the profile of the crawlers of the future gable wall to be implemented, having attached to each end of said line V, the ballast or weight VI, necessary to ensure the permanent tension of the present line V, each end piece mu
nor of its weight VI, will hang at each end of the wall of
link III of the building under construction, ie to the right of each
one of the angles' of walls I and II linked with said connecting wall
III.

 As regards the removal of the device according to the invention, from the gable wall when the latter is completed, it will suffice simply to loosen the through retaining clamps VII, which will suddenly release the elements of sitting in the shape of a U t, during this task, another companion, that is the one who will be on the scaffolding, at the level of the waxing of the present gable, will seize the device by its extreme upper part, in other words the top of the element rectilinear tubular C, in order to slowly bring back to the ground, the monolithic assembly of the present device, since each of its main rectilinear tubular elements A; B and C, are always neutralized by the needle screws 6.

 Once the device has been carefully placed on the ground, we will then loosen the needle screws 6, in order to be able to slide the straight tubular elements B and C to bring them back to their closed phase, the sheath A itself brought back by sliding until 'to the stopper 9 located at 2/3 of the height of the element B. Then, after a final tightening of the said needle screws 6, the device will again be in its closed and locked phase as it is presented on Plate I / 3, in Figure I.
