Description

The invention relates to a metal gantry hock, in particular

  gantry in aluminum profiles arranged between the head of a pole and a half-firm and ensuring the connection between these two elements consisting of a

identical profile.

  Many events or public or private exhibitions take place under marquees. Due to the large number of people participating in these events or to bring together the greatest number

  of people, the tents have been replaced by metal structures

  covered with tarpaulins constituting the roof of said capitals. These structures

  metal rests are made of metal frames more or less

  important, each portico consisting of vertical poles and trusses.

  These porticoes, arranged at regular intervals, are connected to each other by

connecting beams.

  Frequently these events are punctual or

  It is therefore necessary to provide removable capitals. To facilitate the transport and / or handling of gantries,

  these are made of hollow aluminum profiles.

  However, said capitals must satisfy two essential conditions

  tial: on the one hand, to comply with safety standards, and, on the other hand, to be quickly dismountable and / or easily trained. To satisfy these

  two conditions, it turns out that the said capitals are subject to problems

  assembly, especially at the level of the connections between the head of the poles and the ends of the farms or half-farms. Often, we benefit

  a condition of security, an essential condition, but this to the detriment of the

  pity and ease of assembly of poles and trusses. Despite

  that these are made of light metal, but because of their

  they have a certain weight which is all the more difficult to handle when the range is large, that is to say when the transverse distance

  separating the two poles is important.

  The present invention aims to provide a connection between the pole

  and the half farm simultaneously fulfilling the two conditions set out above.

above.

  For this purpose, the invention relates to a metal gantry hock, in particular

  gantry of aluminum profiles disposed between the head of a pole and a half-firm and ensuring the connection between these two elements constituted

  of identical profile, characterized in that it comprises a first solid core

  lidaire of the head of the post and provided with teeth meshing with a - 2 teeth fixed to a second core itself integral with the half, these

  teeth being traversed by locked connection means.

  According to another characteristic of the invention, each core comprises a body conforming to the internal faces of the walls of the section of the head of the post and the profile of the half-firm. The advantages obtained by this invention consist essentially in that at the location of the hock, the aluminum profile of the column head and the aluminum profile of the half-farm are consolidated, which makes it possible to satisfy the conditions of the safety and that, moreover, because of the meshing of the two teeth, it is easier to assemble the post and the

  half-closed or firm. Thus, this hock simultaneously satisfies both conditions.

  essential requirements, namely the safety condition and the condition of assembly.

  ge and / or easy dissolution of the bond.

  An advantageous embodiment of the invention provides that the axis

  median of the teeth is parallel to the longitudinal median axis of the half-tooth.

  As a result, said teeth can be given a relatively large length and thus increase the cooperation between the teeth. It results

  a consolidation to the right of assembly of the post and the half-farm.

  Another application of the invention is obtained by a pre-conceived design.

  seeing that the teeth of the two toothings include means of autocenter-

  ge, which facilitates the interpenetration of the teeth of the two teeth and, by

  way of consequence, the establishment of the half-farm on the head of the pole.

  The invention will be better understood with reference to the following description

  made by way of non-limiting example and in the attached drawing in which:

  FIG. 1 is a partial view in elevation of a gantry showing the em-

  placement of the hock according to the invention.

  FIG. 2 is a sectional view along section line I1-II of FIG. 3.

  FIG. 4 is a section of the teeth of the second integral core of the

spun from the half-farm.

  FIG. 5 is a section of the toothing of the first integral core of the

head of the pole.

Reference is made to FIG.

  The capital is formed of metal gantries 1 arranged at intervals

  regular and interconnected by connecting beams 2, 3.

  metal products 1 are composed of farms and / or half-farms 4

  the lower end 5 is connected to the head 6 of posts 7 via the

  re of a link constituted, in accordance with the invention, by a hock 8.

  - Both the farm and / or the half-farm 4 that the post 7 are made of metal profiles and more particularly aluminum profiles or other light metals. To reduce the weight of the frames 1, these aluminum profiles are hollow tubular sections and for reasons of normalization, the hollow aluminum tubular sections of the farms and / or half-farms 4

  are the same as hollow aluminum tubular sections of columns 7.

  When seen in plan, the profile of the post 7 is arranged perpendicularly with respect to

  port to the profile of the farm and / or half-farm 4.

  The present invention relates more particularly to the hock 8 allowing

  both the assembly of the farm and / or the two half-farms 4 and the head 6

poles 7.

Referring to Figures 2 and 3.

  According to the invention, the hock 8 comprises a first core 9 engaged in the open end 10 of the head 6 of the post 7. This core 9 has a body 11 conforming to the inner faces 12, 13 of the walls 14, 15 of the profile 16

  of which post 7 is formed. Because said body 11 matches the faces

  12, 13 of the walls 14, 15 of the section 16, it consolidates the latter. Indeed, it can be considered that the thickness 17 of the profile 16 of the thickness 18 of the walls 19, 20 of the core 9 is increased. However, in order to lighten the hock 8, the core 9 comprises a hollow central portion 21. To make said core 9 integral with the head 6 of the post 7, it is made in the walls

  14, 15 of the profile 16 and in the walls 19, 20 of the core 9 a plurality of ori-

  22, 23, 24, 25 through which is engaged a fastener 26

  such as bolt or equivalent. Of course, the number of these

  fasteners 26 is determined by the safety standards. The singing

  upper 27 of the core 9 protrudes slightly with respect to the upper edge

28 of the head 6 of the post 7.

  On said upper edge 27 of the core 9 is fixed by any means

  that a base 29 of a toothing 30 whose teeth 31, 32 are directed towards the

  above. According to the invention, the median axis 33 is parallel to the longitudinal median axis.

of the half-farm 4.

  Moreover, the shank 8 comprises a second core 34 threaded in the end.

  The core 34 also has a body 35 conforming to the inner faces 36, 37, 38, 39 of the walls 40, 41, 42, 43 of the profile 44 of which the half-firm 4 is formed. Because the profile 44 of the half-firm 4 is the same as the profile 16 of the post 7, the two cores

  9 and 34 are of identical section. The length 45 of the core 34 is relative to

  4 and greater than the length 46 of the toothing 30. It is practiced in the walls 47, 48 of the core 34 and in the walls 40, 41 of the profile 44 a plurality of orifices 49, 50, 51, 52 to through which passes an element of

  fixation 53, 54, 55 such as bolt or equivalent element.

  To avoid deformation of the core 34, in particular by a closer

  lateral walls 47, 48, said core 34 is consolidated by means of

  strong 56, 57 forming spacer and annihilating any risk of said approximation.

  The toothing 30 meshes with a toothing 58 disposed against the outer face.

  dull 59 of the lower wall 42 of the profile 44. The teeth 60, 61, 62 of this-

  Teeth 58 are directed downwards and the teeth 31, 32 of the toothing 30 of the core 9 housed in the head 6 of the post 7 are interposed between the teeth 60, 61, 62. The teeth 31, 32 of the toothing 30 and the teeth 60, 61, 62 of the toothing 58 are parallel to the central axis 33. The toothing 58 is rendered

  secured to the core 34 by fixing elements 63, 64. These latter

  pour an orifice 65 formed in the lower wall 42 and an orifice 66 formed in the toothing 58 and are screwed into threaded holes 67, 68

  made in the lower wall 69 of the core 34. The heads 70, 71 of these ele-

  fasteners 63, 64 are embedded in the recesses 72, 73 between the teeth -61 and 61-62. At the location of these heads 70, 71, the teeth 31, 32 of the toothing 30 comprise a recess 74, 75 in which can be housed

said heads 70, 71.

  Because the farm or the half-farm 4 has a certain length and thus is difficult to handle, the tops 76, 77, 78 are given teeth 60, 61, 62 of the toothing 58 and the tops 79, 80 of the teeth 31. , 32 of the toothing 30 of the self-centering means, which facilitates the interpenetration

  teeth 31, 32, 60, 61, 62 of the teeth 30 and 58. These means of self-cleaning

  trage are guide ramps 81, 82, 83, 84, 85, 86, 87, 88 made in the flanks 89, 90, 91, 92, 93, 94, 95, 96 of the teeth 31, 32, 60, 61, 62

(see Figures 4 and 5).

  To hold the two sets of teeth 30 and 58 together after the interpéné-

  tration of their teeth 31, 32, 60, 61, 62, the hock 8 comprises means

  locked link. These means are arranged perpendicularly with respect to

  port to the central axis 33 of the teeth 30 and 58 and pass through orifices 98,

  99, 100, 101, 102 made in the teeth 31, 32, 60, 61, 62. According to one example,

  non-limiting embodiment, the connecting means are pins 103

  one of whose ends 104 is frustoconical to facilitate the introduction of

  said pins 103 in the successive orifices 98 to 102. At the other end

- 5 -

  , the pins 103 comprise an operating handle 106. However, to prevent the pins 103 inadvertently exit said orifices 98 to 102, said pins 103 have a locking element 107. This is constituted for example by a washer, integral in rotation with the pins 103, and having a flat part 108. In the locking phase, the locking element 107 clings behind the active face 109

  at least one striker 110 secured to the outer flanks of the toothing 58.

  The height 111 of this active face 109 is such that after rotation of one hundred and eighty degrees of the pin 103, the cooperation between the

  keeper 110 and the locking element 107.

  Although the invention has been described with respect to a particular embodiment, it is understood that it is not limited thereto and that

  can make various modifications of shapes, materials and combinations

  of these various elements, without departing from the framework and

the spirit of the invention.
