The pin comprises an expansion body (2) and, around the body, an expandable tubular sleeve (3) made from a flexible material, with a stop collar (12) and an end (10) forming a nut. With the pin extending through an orifice pierced in the wall with the sleeve collar (12) bearing against the front face of the wall, the nut (10) interacts with an end part of the body, is driven towards the collar (12) and brings about the expansion of the sleeve (3) and its squashing against the rear face of the wall. The body (2) is tubular, in order to receive a screw for fixing a piece upon the wall, and has, unlike the end part, a collar (7) for bearing against the one (12) on the sleeve (3). The sleeve (3) is plastically deformable and means (42) are provided for preventing the rotation of the body (2) with respect to the sleeve (3) in the opposite direction to the direction of expansion. The end of the body (2) is provided with a piercing bit (4).The pin of the invention can be applied well to bricks.

A pin for fixing a panel to a support material is provided, having a shank (1) and a head (4), and a narrowed anchorage portion (5), a washer (2) for pressing the panel to be fixed against the support material and a guide (3) for limiting the penetration depth the shank (1). The pin, to be anchored within a material supporting the panel by means of a powder actuated tool does not damage the panel and ensures fixing of the pin with very good quality The guide (3) comprises a cylindrical tube which forms a hole within the panel, within which the cylindrical tube guide (3) is disposed so as to serve as a guide for the shank (1) of the pin as the same is being driven therethrough and into the support material.

Method and assembly for fixing a surfacing stabilising mesh and a piece for holding the fixing assembly. According to the method for fixing a mesh formed by interlaced strands (5) to a supporting material (3) after laying the mesh on the supporting material (3), the first wings (4) of the holding pieces with two wings (4, 6) are passed underneath the strands (5) of the mesh, the pieces being closed around the strands (5) and secured to the supporting material (3) by anchoring in the material (3), by means of an anchoring appliance, a single fixing component (2) for forming holding lugs (7) from the pieces (1) and securing the assembly to the supporting material (3).

The bolt assembly comprises a traction shaft 1 with an anchoring extremity 13, an expansion ring 2 formed by means of expansible leg elements 18,19, and a brace 3 disposed around the shaft 1 and supported against a shoulder 24 provided upon the expansion elements 18, 19 in order to provoke expansion of leg portions 22, 23 with an undercut portion of an anchoring hole. The expansion elements 18, 19 extend between the shaft 1 and the brace 3 so as to give the latter a bearing surface of the same length as the legs 22, 23. The shoulder zone 24 defines an articulation region for the legs 22, 23.The bolt assembly is used for the fixing of pieces within a zone subject to tensile forces within a building material.

The present invention relates to a self-closing propellant charge package adapted for use with a gravity operated loading device of a power-actuated tool. The package comprises a tubular body having one end at least partially closed, the other end being open. A portion of the body adjacent the open end is deformed for holding the charges, it being possible to cancel the deformation of this portion to allow passage for the charges. More specifically, at least one cut-out is provided in the deformable portion, the portion being maintained in a deformed state by a resilient ring or other means.

The indirect-firing apparatus includes a combustion chamber for a cartridge (62), a trigger for igniting the cartridge, a barrel, an inertia block in the barrel, an anchor guide (7) designed to receive an anchor, a shuttle (34) in the anchor guide (7) mounted for movement from an anchor loading position to a position for firing and driving of the anchor, mechanisms (63, 11, 46) for displacement of the shuttle from one position to the other, and a barrel holder (61) for concomitantly controlling the closure of the combustion chamber (3) and means for displacement of the shuttle (34). The mechanisms (63, 11, 46) for displacement of the shuttle (34) are arranged so as to drive the shuttle (34) beyond the firing position (25). Damping components (33, 38), when the shuttle (34) has reached its firing position (25), absorb the action of the displacement mechanisms (63, 11, 46).

A cartridge has a multiple casing comprising an outer casing (1) with a front end piece (2) for receiving an application nozzle and an annular rear thrust wall (4) mounted slidingly in the outer casing (1), and at least one inner casing (5) with a front end piece (6) extending inside the end piece (2) of the outer casing (1) and a disc-shaped rear thrust wall. Shoulders and rib (8, 14, 16) for connecting the two outer (1) and inner (5) casings together ensures their mutual locking in axial and radial positions. A drive assembly is structured like the cartridge. The invention is well suited to the application of sealing resins.

An explosive tool driving apparatus is provided having an improved extractor mounted upon its barrel holder, and the claw of which is meant to retain the case of a propulsive charge during opening of the apparatus. A groove for passage of the claw of the extractor is formed within the barrel of the apparatus. In the firing position, the claw is disposed in front of an abutment shoulder for the collar of the case, so as to provide an initial axial clearance, the extractor is freely movable in translation between two axial stops and, during opening, is moved forwardly by the means of collar of the case the improvement thereby avoiding the hard point during opening of the apparatus
摘要:
The apparatus comprises along the riser (10) a return chamber with a front space (30) and a rear space (22) adapted to communicate with the combustion chamber (15) following a first displacement of the riser (10). Once the two spaces (30, 22) have been brought into communication with one another, they are separated from one another and the riser (10) is returned towards the rear in the barrel (9). The two spaces (30) and (22) communicate with one another during the displacement of the riser (10) and the rear space (22) is separated from, the front space (30) following a second forward displacement of the riser (10). As the rear space (22) communicates with the exterior of the apparatus, the expansion of the combustion gases trapped in the front space (30) then returns the riser (10) towards the rear into the firing position. The apparatus serves to fix components to a support material.
