FR2965285A1 - Tile supporting equipment for use during construction of building, has shoe that is constituted of angle bracket and fitted on fixation system, and adjusting system adjusting height of equipment - Google Patents

Abstract

The equipment has a shoe (7) that is constituted of an angle bracket and fitted on a fixation system, where the fixation system fixes the equipment on a bearing wall. A lateral face of the equipment is pierced with a hole for passing a clamping axis of a parallelepiped head of a fixation screw (8) with the shoe. The parallelepiped head of the screw is mechanically welded for being inserted in a housing arranged under a horizontal face of the shoe. An adjusting system e.g. jack, adjusts height of the equipment.

Description

When building a building, it is more and more common to use prefabricated concrete slabs to make the floors. These slabs can be prefabricated to the desired length, they are simply keyed at each end on the load-bearing walls, as shown in Figure 1, where are symbolized the load-bearing walls (2) with their recess and the prefabricated slab (1). During these keying operations, the bearing surface of the receiving wall must be temporarily increased for safety reasons. This is usually done with wooden or aluminum beams, these beams are leveled with respect to the bearing wall bearing and supported along it either with simple props or with shoring towers. FIG. 2 represents a beam (4) supporting the slab (1) with props (3) along the recesses of the walls (2) on which the ends of the slab are keyed;

This type of solution has a certain number of drawbacks: - heavy set-up, in particular during high-altitude operations, particularly in corridors and angles. - Important safety issues for support by struts. - Heavy dismantling and moving equipment at the same level and even higher level. the height adjustment is difficult and imprecise.

The present invention relates to a fixture in the wall for supporting with other identical equipment a concrete slab during the keying of its ends on the load-bearing walls. This invention eliminates the previously mentioned disadvantages.

The equipment is presented symbolically in FIG. 13. It comprises according to a first characteristic5 - a wedge-shaped shoe (40) providing partial support for the end of the slab via the beam - a system of fastening (44) of the load-bearing equipment on the load-bearing wall - a jack system (41) for adjusting the height - a turntable (42) - an accessory for adjusting the beam to the turntable (45)

This equipment, according to a first embodiment, is shown in position in Figure 3. In addition to the slab (1), the beams (4), the walls (2) the equipment is shown in (6). FIG. 5 details the various parts of this embodiment: - shoe (7) - fastening screw (8) of the equipment on the wall - support washer (9) - tightening nut (10) - adjusting cylinder in height (16) '- plate (4) - adaptation accessory (11) - clamping screw (15) - clamping nut (12) - clamping pin (13) Figure 4 in exploded view shows the relative mounting of these different pieces.

The shoe (7) and Figure 7 consists of a bracket (24) obtained from a square tube of large thickness slanted cut and delicately. This shoe is welded to a thick sheet metal support plate, in this plate is made an opening through which the head of the fixing screw passes and on the edges of this opening bears this head. In the upper part of the shoe is welded a handling handle (17) made from a bar of circular section curved V-shaped. The horizontal portion is pierced with a circular hole (21) for the passage of the cylinder and d an oblong opening (18) for manual gripping of the equipment.

A side face is pierced with a hole (19) for the passage of the clamping axis (13) of the head of the fastening screw (26) with the shoe.

The fixing screw (8) and Figure 8 of the equipment on the wall consists of a threaded rod (25) capable of withstanding shear and bending forces of several deca Newton, the head (26) of this screw is a mechanically welded parallelepiped sized to fit into a specially designed housing under the horizontal face of the hoof. The lateral faces are traversed by a bore (27) for the passage of the clamping pin (13).

The bearing washer (9) is a square plate of sufficient size to reduce the punching force of the nut on the wall, it pierced with a hole for the passage of the threaded rod.

The clamping nut (10) and FIG. 12 consists of a rectangular plate with 45 ° folded ends (38). This sheet is pierced with a hole in its center, a hexagonal nut (39) is welded above this hole.

The height adjustment cylinder (16) consists of a screw (28) capable of supporting loads of several tons in its axis, this hexagonal screw (31) has at its other end a bearing washer (29). for the recovery of the load. The nut (30) is supported to bear on the edge of the practical hole on the upper face of the shoe.

The plate (4) is a folded thick plate (32) pierced with a central hole (33) for the cylinder and two lateral holes (34) for attaching accessories.

The adaptation accessory (11) is a mechanically welded part in the form of a fork provided with two housings (37) offset downwards and pierced with a hole for clamping on the plate.

The clamping screw (15) is a commercial screw type "hammerhead". The clamping nut (12) is a standard butterfly type nut.

The clamping pin (13) of the head of the fastening screw with the shoe body is made from a curved circular section bar (45) on which is welded a slotted washer (46) for locking. 5
