Definitions
- the present invention relates to a device for connection of two parts of a boiler.
- connection area is reinforced between the hearth and the flue, that is to say the conduit. This is however difficult in the case of large boilers cut.
- the present invention provides a connecting device simple and reliable mechanism for transferring static or dynamic forces of part of the boiler to the other.
- the invention comprises at least one link articulated at its two ends, one of its joints, called the first joint, being connected by fixed way to the first wall at a first point thereof and the other joint, called the second end, being slidingly connected vertically to the second wall, the connecting rod being more permanently connected vertically to the first wall at a second point of this one.
- the distance between the first point and the second point is determined so that the resulting horizontal displacement vertical displacement due to differential expansion and the inclination of the link is compatible with the permissible horizontal relative displacement of the second part compared to the first part.
- the second articulation is connected by sliding vertically to the second wall by via an upright slidably mounted on the wall.
- the link is fixedly connected vertically to the first wall in one second point thereof via a cross integral with said upright and fixed to the first wall of vertically fixed at this second point.
- the link is fixedly connected vertically to the first wall in one second point of it via a second rod whose first end is articulated on the connecting rod and whose second end is articulated in said second fixed point of the first wall.
- the first end of the second rod can be articulated on the second articulation.
- the first articulation is fixed on an upright secured to the first wall in said first point.
- the device for connecting two parts of a boiler generally includes several devices such as specified above divided between the first and the second wall.
- Figure 1 is a front view of a boiler in two parts.
- Figure 2 is a front view of a first mode of realization of the connection device according to the invention.
- Figure 3 is an enlarged view of a part of figure 2.
- Figure 4 is a front view of a second mode of realization of the connection device according to the invention.
- Figure 5 is a similar view of a variant of production.
- a two-part boiler as shown in figure 1 has a main focus 1 and a flue rear 2 connected by a conduit 3 disposed at their part superior. Focus 1 is guided by links sliding doors not shown and in known manner on a support building and the flue 2 is therefore cantilevered on the hearth 1.
- a connection device is installed in zone 4 and connects wall 1A of fireplace 1 and the wall 2A of the flue 2 which are opposite.
- this connecting device comprises at least one link 10 articulated at both ends and inclined at an angle ⁇ to the horizontal plane.
- first articulation 10A One of its joints 10A, called the first articulation, is fixedly connected to the first wall 1A at a first point P thereof.
- first articulation 10A is fixed on an upright 11 secured to the first wall 1A at this first point P.
- This upright 11 is, apart from this point P, mounted sliding vertically on slides 12A, 12B. It rests by elsewhere on sections 13A, 13B for reinforcing the wall 1A.
- the other joint 10B is slidingly connected vertically to the second wall 2A. To do this, it is integral with an upright 14 mounted sliding on the wall 2A by means of profiles 15A, 15B and supported on profiles 16 for reinforcing the second wall 2A.
- the rod 10 is moreover fixedly connected vertically to the first wall 1A at a second point Q of this one.
- a cross member 17 secured to the upright 14 is fixed to the first wall 1A in a fixed manner vertically in Q.
- the uprights 11, 14 are connected by several similar rods 10, 20 in order to ensure a better stability of the structure thus produced and connect the walls 1A, 2A over a major part of their area.
- FIG. 3 represents in more detail the link 10.
- the link 10 turns on its articulation 10A and its second joint is displaced by a displacement vertical ⁇ y and a horizontal displacement ⁇ x less than ⁇ y.
- the upright 14 slides vertically on the wall 2A of the displacement ⁇ y and therefore it suffices to choose the angle ⁇ and the distance between the first point P and the second point Q such that the wall 1A between these points expands by the value ⁇ y allowing to obtain a displacement ⁇ x compatible with the horizontal expansion of the duct 3.
- the rod 10 therefore rigidly connects the two walls 1A, 2A while allowing differential expansions of these walls, the resulting horizontal displacements being kinematically compatible with these expansions.
- FIG. 4 represents another embodiment of the connecting device.
- This connection device comprises at least one link 10 articulated at both ends and inclined at an angle ⁇ .
- One of its joints 10A is fixedly connected to the first wall 1A at a first point P thereof.
- the first articulation 10A is fixed for example on a section 13A for reinforcing the wall 1A.
- the other joint 10B is slidingly connected vertically to the second wall 2A. To do this, it is slidably connected to an upright 14 secured to the wall 2A at a point 15C and sliding on the latter at the level of the sections 15A and 15B.
- the rod 10 is moreover fixedly connected vertically to the first wall 1A at a second point Q of this one.
- a second link 30 has its first end 30A articulated on the second articulation 10B of the rod 10 and its second end hinged in this second fixed point Q of the first wall 1A by through profile 13B.
- the joints 10B and 30A are cylindrical connections in vertical lights integral with the upright 14.
- the walls 1A, 2A are connected by several sets of links 10, 20, 30, 40 similar or symmetrical.
- the variant shown in Figure 5 does not differ from the previous embodiment only by the fact that the second rod 30 has its first end 30A articulated on the rod 10 at a point thereof different from its joint 10B. So, by a multiplier effect, we obtain a distance between points P and Q lower and therefore a less bulky device.
