Construction joint profile

Abstract

The invention relates to a device for carrying out concrete repairs on reinforced concrete slabs or walls. This device consists of a trapezoidal profile 1 made of folded sheet steel, which makes it reusable. On its small base, the profile 1 has one or more rectangular rebates 2 designed to receive the reinforcement bars 8, which are held in place by steel wire clamps 4, manually positioned in holes 5 located in the upper part of the profile 1 and on the inner side of the rebate(s) 2.

Description

The addendum to patent No. 88 15490 relates to an improvement in the design of the concrete transfer profile, initially described. This device is also intended to ensure the resumption of concreting of slabs or reinforced concrete walls. The device will be better understood with the help of the following figures: Fig 1 is the front view of the concrete transfer profile (1), (scale 1). Fig. 2 defines a cross-section of the concrete construction joint profile (1), (scale 1). Fig 3 defines the mounting of the profile (1 > on a WOOD formwork. The concrete pouring joint profile (i) is characterized by a preferably trapezoidal shape. The mat-rl u constituting the concrete transfer profile (1) is made of folded steel sheet; the material thickness can be between 10 / 10ths and 20 / 10ths. This characteristic gives this equipment the specific feature of being reusable. The dimensional characteristics of the concrete transfer profile (1), (length and width) are a function of the dimensions, (height and thickness of the elements to be assembled. The thickness of the concrete transfer profile (l) is preferably 4 cm. On its small base, the profile (l) has one or more rebates (2), preferably rectangular in shape1 intended to receive the sewing frames (8). The placement, center-to-center spacing, width and depth of the rebates (2) are defined, originally, for each type of profile, according to the dimensions of the reinforced concrete elements to be assembled and the diameter of the stitching reinforcement (8). The sewing frames (8) are held in their housing by clips (4), preferably made of 30 / 10th diameter steel wire, positioned manually in holes (5) located in the upper part and on the inner side of the rebate(s) (2). Between the rebates (2), one or more notches (3), rather triangular in shape, were made in order to improve adhesion at the location of the concrete pouring resumption. On the large base of the concrete pouring profile (1), one or more stiffeners (7), preferably made of flat iron, connect the two wings of the latter, to avoid possible deformation of the steel sheet, during demolding. In the middle of the small base of the concrete transfer profile (I) and the inner side, spacers (6) are welded, intended to improve its fixing on the formwork elements. The connection between the concrete pouring joint profile (1) and the formwork (9) is ensured by steel nails (in), on a formwork WOOD, or by a system of magnets on a METAL formwork. At each end of the concrete pouring profile (1), a chamfered part is provided to facilitate formwork removal. The device thus defined allows for all concrete pouring joints to be made. Furthermore, due to its composition, the concrete pouring joint profile (I) is reusable after formwork removal. Indeed, it is enough to nail or fix the profile (I) on the panel at the location of the concrete pour, and to put in place the stitching reinforcements (8). After the concrete has set, the profile (1) is removed from the formwork, then cleaned
