Abstract

The protection barrier comprises a long block (2) with male (10) and female (11) connecting parts on the front (3) and rear (4) faces. These connections enable connecting to similar blocks to form the barrier.

Description

The present invention relates to a protective element

  tion for site, comprising a block of general shape al-

  along and, at a front face and a rear face of the block, male and female connecting members combined to connect said element to other similar elements and

  thus form a protective barrier.

  The invention applies in particular to the elements

  protection whose block is made of concrete.

  Document FR-B-2 632 671 describes such a protective element in which the front face is provided with a male interlocking member and the rear face is provided with a female interlocking member. The male interlocking member is formed by an I-shaped metal section partially embedded in the concrete block. The female interlocking member is formed by a C-shaped metal profile completely embedded in the concrete block. To form a protective barrier along a site bordered by vehicles, several of these elements are assembled end to end by relative vertical sliding

  front and rear faces of successive elements.

  To fulfill its protective role, such a bar-

  rière must be relatively impassable for vehicles

  cules along the site, and legislation tends to impose

  increasingly severe constraints on resistance

  shock resistance of such barriers.

  To meet these constraints, the protective elements must each have a relatively large weight and stability. In addition,

  connections between the successive elements of a barrier must

  wind limit the possibilities of deformation of the barrier in a horizontal plane in the event of an impact, while allowing

  sufficient deformation of the barrier in a green plane

  tical to allow the barrier to adapt to gradient

tees of the ground on which it rests.

  It can be seen that the protective element described in

  the aforementioned document does not meet the new

  the constraints imposed by legislation.

  The invention aims to solve this problem by providing a protective element for forming

  barriers of increased impact resistance, but which can

  wind, however, satisfactorily embrace the

tees of the ground on which it rests.

  To this end, the subject of the invention is an element of

  protection for construction sites, comprising a block of general form

  elongated rail and, at the level of a front face and a face

  rear of the block, male and female connecting members

  judged to link said element to other analogous elements

  gues and thus form a protective barrier, characterized in that the element comprises, respectively at the level of the

  front and rear side of the block, a connecting member

  its male and a female connecting member.

  According to particular embodiments, the protective element may include one or more of the following characteristics, taken in isolation or in any technically possible combination: - the male and female connecting members of the front face have a reverse relative position that of the male and female connecting members of the rear face; the male connecting members each comprise a T-shaped part, at least part of which is in

  protruding from the corresponding face of the block, and the

  female connection nes each include a profi-

  lée in C located inside the block relative to the corresponding face of the block; - The protective element comprises for at least one connecting member, a reinforcing lining integral with this connecting member and the block, and this lining extends transversely said connecting member; - Said or each reinforcement lining extends the corresponding connecting member transversely on both sides; - Said or each reinforcement lining has at least one transverse dimension practically equal to the minimum transverse dimension of the block;

  - said or each reinforcement lining is a gar-

  protection of the block which covers at least partially-

  the corresponding face of the block; the protective element comprises a reinforcement lining for each connecting member of at least one face of the

  block and these reinforcing linings of this face are solid

  daires; and - said or each reinforcement lining comprises at

  at least one plate extending transversely to said block.

  The invention further relates to a site protection barrier, characterized in that it comprises several protection elements as defined above connected to each other by the male connecting members

  and females of the front and rear faces of the pro-

successive tection.

  The invention will be better understood on reading the

  description which follows, given only as

  example, and made with reference to the accompanying drawings, in which: FIG. 1 is a schematic perspective view of a protective element according to the invention,

  - Figure 2 is a schematic perspective view

  the protective element of figure 1.

  Figure 1 shows a protective element 1

  for building sites which rests on the ground.

  In all that follows the terms "lower" "upper", "up", "down", "vertical" and "horizontal" ... are understood with respect to this position

protection element 1.

  The protective element 1 comprises a block 2 of baby

  tone, which is generally prismatic in shape with an elongated axis

  horizontal, and which is equipped with connecting members which

will be described later.

  Block 2 has a front face 3 and a rear face

  rier 4 opposite, a base 5, and a top 6 of width 1

  significantly less than the width L of the base 5.

  Block 2 also has lateral faces 7

opposite concave profiles.

  The transverse profile of block 2 is converging towards

  the top and symmetrical about a vertical median plane.

  This transverse profile successively comprises a rectangle of width L = 60 cm and height 10 cm corresponding to the base 5, a first isosceles trapezium of 30 cm in height and the small base of which measures approximately 30 cm, and a second isosceles trapezium of 40 cm high and whose small base measures 1 = 20 cm. Thus, the total height H of block 2 is

  about 80 cm and its total length is about 350 cm.

  In variants not described, the dimensions of the

block are different.

  The base 5 preferably includes notches 8

  transverse formed in the underside 80 of the block 2.

  The protective element 1 comprises at the level of the

  front face 3 and rear face 4 of block 2 of the assemblies

connecting tubes 9 by interlocking.

  These connection assemblies 9 each comprise an or-

  male gane 10 for interlocking connection and a female member 11 for interlocking connection arranged one above the other. Male 10 and female 11 organs of sets 9

  front and rear are identical.

  As illustrated by Figures 2 to 4 which represent

  tent the connection assembly 9 of the front face 3 before the block 2 has been poured, the male interlocking members 10 are formed by metal T-profiles oriented vertically. These male members 10 each comprise a vertical core 12, oriented parallel to the axis of the block 2, and a vertical wing 13 orthogonal to the core 12. The wing 13 is

  generally rectangular in shape with its upper ends

  lower and bevelled as indicated by the arrows

ches 14 in Figures 1 and 2.

  The female nesting members 11 are formed

  by vertically oriented C-shaped metal profiles.

  These female organs 11 each comprise a vertical core

  15 and two vertical branches 16 separated by a slot 17.

  The male 10 and female 11 organs of the sets of

link 9 are conjugated.

  Thus, the dimensions of the nesting members fe-

  11 are adapted so that each female organ 11

  can receive, with a certain clearance, a wing 13 of a gold-

  male gane 10 between its branches 16 to its core 15, and to allow the passage of the core 12 from this male member 10 to

  through the slot 17 of the female member 11.

  The connection assemblies 9 of the front face and the rear face are symmetrical with respect to each other

  a median horizontal plane P shown in FIG. 5.

  Thus, the two connection assemblies 9 are distinguished

  essentially because the interlocking member

  male 10 is disposed above the female interlocking member

  11 for the connecting assembly 9 before, while the female interlocking member 11 is disposed above the male interlocking member 10 for the connecting assembly 9

rear 4.

  Due to the aforementioned symmetry, only the whole

  9 of the front face 3 will be described in detail below.

  below opposite Figures 2 to 4.

  This connection assembly 9 comprises a reinforcement lining 20 of the male member 10 itself consisting of two

  vertical metal plates 21, substantially rectangular

  res and which extend on either side of the end 22 of the core 12 opposite the wing 13. The lining 20 is orthogonal to the core 12 of the member 10 and each plate 21 East

  welded to the core 12 by a vertical weld bead 23.

  The lining 20 transversely extends the male member 10. It is understood by this that the largest transverse dimension of the lining 20 is greater than the most

  large transverse dimension of the male organ 10, and in particular

  ment of its active part, namely the wing 13. Thus, as can be seen in FIG. 3, the width Lm of the lining 20

  is clearly greater than the width lm of wing 13. -

  As seen in Figure 1, the width Lm of

  the reinforcement lining 20 and substantially equal to the width

gor 1 of the top 6 of block 2.

  The connection assembly 9 further comprises a lining

  vertical structure 25 for reinforcing the female member 11. This lining 25 is coplanar with the lining 20 and it is

  formed of two vertical plates 26 rectangular and identical

  ticks. These two plates 26 are welded by vertical cords 27 on the external face of the branches 16 of the female member 11 without closing or limiting the dimensions of the slot 17. Thus, the plates 26 are arranged edge to edge.

  edge with the branches 16 at the level of the slot 17.

  On the other hand, these plates 26 extend transversely-

  ment outwards beyond the edges of the branches 26. The total width Lf of the lining 25 is then greater than the width if of the core 15 of the female member 11. Thus, the plates 26 extend transversely the female organ 11

from either side.

  The reinforcement linings 20 and 25 are welded to each other by a horizontal weld bead 28 so that the lining 25 extends the lining 20. The two linings 20 and 25 are substantially of the same height being worth approximately H / 2 and of substantially the same width which is approximately 1. The two linings 20 and 25 therefore form a substantially rectangular plate which extends practically over the entire height of the block 2.

  The connection assembly 9 also includes a plate

  that 30 closing the upper end of the female member 11. This plate 30 is connected to the plates 20 and 25 by the

weld bead 28.

  An upper central fixing lug 32 is provided at the upper end of the lining 20 and a lower central fixing lug 33 is provided at

  the lower end of the core 15 of the female member 11.

  Finally, a fixing hole 34 is formed in the plate

30.

  The two tabs 32 and 33 are arranged on the side of the face 35 of the connection assembly 9 which is located at

inside block 2.

  Corrugated vertical concrete irons 36 are welded on each side of the inner face 35 of the assembly of

liaison 9.

  As can be seen in Figures 1 and 5, the linings

  tures 20 and 25 are flush with the front face 3 of the

  block 2 by partially covering it.

  The male interlocking member 10 is protruding by

  relative to this front face 3 and the nesting member fe-

  melle 11 is located inside the block 2. The female member 11 opens into the underside 80 of the block 2 and, by the

  slot 17, in the front face 3 of block 2.

  To form the block 2, the connection assemblies 9 as described above are made, for example of steel. Then, there are three longitudinal concrete irons 37, as shown in FIG. 5, between the legs 32,

  33 and the orifice 34 of the connection assemblies 9 front and rear

  laugh. Finally, we introduce all of these metal elements -

  liques in a mold where we pour the concrete to form the

  block 2 and thus obtain the protective element 1.

  To form a protective barrier against a change

  tier, we just successively fit elements 1 as described by relative vertical sliding of the face

  front 3 and rear side 4 of successive elements 1.

  It can be seen that the impact resistance of such a barrier is much higher than that of a barrier.

  formed from protective elements such as that

  written in document FR-B-2 632 671.

  Indeed, we note that the possibilities of movement-

  relative elements, and in particular of pivoting, in a homo plane

  rice of two successive protection elements 1 are limited. In addition, for each protective element 1, the linings 20 and 25 reduce the risk of displacement of the

  male 10 and female 11 organs relative to block 2 cor-

  respondent, and in particular the risks of uprooting.

  In addition, the linings 20 and 25 play the role of protective lining preventing damage to the front and rear faces 3 and 4 of the concrete block during an impact with an adjacent protective element 1. The linings 20 and 25 therefore limit the risks of loosening the connection assemblies 9 of a block 2 during impacts against the barrier.

protection.

  Furthermore, elements 1 according to the invention em-

  boxed to form a barrier each have a behavior

  more symmetrical impact resistance than the elements

  the above document, each front and rear side pre-

  sensing a male organ 10 and a female organ 11.

  We can see that the possibilities of relative movements

  tifs, and in particular pivoting, in a vertical plane are relatively good and allow the barrier thus formed to adapt correctly to the profile of the ground on which it

rests.

  According to a variant not shown, the linings

  and 25 are not integral with each other. This va-

  laughing increases the relative freedom of movement of the male member 10 and the female member 11 of the front faces 3

and rear 4.
