Abstract

PURPOSE: To simplify structure and enhance safety by fixing the lower end of a vertical board, which is provided with a bracing notched area on the upper end, with the central area of a base board and fixing a reinforcing board with both sides of he vertical board and the base board. CONSTITUTION: The lower end of a vertical board 12 provided with a bracing notched area 11 on the upper end is welded and fixed with the center of a square-shaped base board 10 where a reinforcing board 13 formed in the shape of a right angled triangle with a cut head is welded and fixed with both sides on the center of the vertical board 12 and the base board 10. Then, a spacer is placed on permanent concrete 2 with a specified spacing. A lower reinforcing bar 14 is fitted into the notched area 11 where a middle reinforcing bar 15 and an upper reinforcing bar 16 are placed thereon so that the reinforcing bars may be placed into a mat slab 1.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a spacer for mat slab reinforcement.

[0002]

2. Description of the Related Art Conventionally, to arrange the mat slab 1,
As shown in FIG. 6, a plurality of V-shaped streaks 3 and a horizontal streak 4 for connecting the V-shaped streaks 3 on the soil or waste 2 constitute a spacer for mat slab reinforcement, or FIG. As shown in Fig. 2, an L-shaped angle 5 is placed on the soil or waste container 2 and fixed by anchor bolts 6, and a second L-shaped angle 7 is vertically welded to the L-shaped angle 5, and a third L-shaped angle is formed thereon. The angle 8 was horizontally welded to form a spacer for the mat slab reinforcement.

[0003]

However, in that case, the structure is complicated, and labor such as welding is required, resulting in an increase in cost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, in which the lower end of a vertical plate 12 having a notch 11 for receiving a line 14 at the upper end at the center of a base plate 10 is provided. This is a spacer for reinforcing the mat slab, which is fixed and the reinforcing plates 13 are fixed on both sides of the vertical plate 12 and the base plate 10. In addition, a plurality of streaks 14 are provided in the cutout portion 11a.
It was intended to receive.

[0005]

A plurality of spacers are placed at a predetermined interval on the soil or the waste container 2, the lower streak 14 is fitted in the notch 11, and the mat slab 1 is further formed thereon.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 4, the lower end of a vertical plate 12 made of an iron plate having a notch 11 for receiving a streak at the upper end is welded to the center of a base plate 10 made of a square iron plate. After fixing, the reinforcing plate 13 made of an iron plate in the shape of a right-angled triangle is fixed by welding on both sides of the center of the vertical plate 12 and the base plate 10. Since the present invention has such a configuration, in order to reinforce the mat slab 1, as shown in FIG. 1, a plurality of mat slabs are placed at a predetermined interval on the soil or the waste container 2,
The lower reinforcement 14 of 38 mm which constitutes the mat slab 1 is fitted in the notch 11, and the middle reinforcement 15 and the upper reinforcement 16 of 25 mm or 38 mm which constitute the mat slab 1 are further placed thereon to arrange the mat slab 1. The thickness of the middle and upper muscles may be arbitrary.

Thus, when concrete is driven into these mat slabs 1, the concrete flows into the through holes formed in the head of the reinforcing plate 13 of the spacer, and is firmly fixed to the concrete. FIG. 5 shows another embodiment of the present invention in which a plurality of (two) streaks are received in the notch 11a of the vertical plate 12.

[0008]

As described above, according to the present invention, since a plurality of spacers are simply placed on the soil or the waste container 2 at a predetermined interval, the work is simple, the labor cost can be reduced, the cost is low, and the mat is Since the lower streak 14 constituting the slab 1 is fitted into the cutout portion 11, the lower streak 14 is stable and can sufficiently withstand a mat slab having a large-diameter heavier weight.
