Abstract

PROBLEM TO BE SOLVED: To provide a method for curing concrete in which a concrete curing sheet can be laid by one member without touching an anchor bolt projected from the top end face of forms in foundation works for dwelling construction. SOLUTION: Both ends of the curvedly formed member are formed in an approximately U shape that the approximately U-shaped section of the top end face of the forms can be held as a method for fixing and holding the concrete curing sheet on the member to the forms, and the sheet and the member can be held simultaneously to the forms by the elastic force of the member.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for curing concrete after placing concrete in a foundation work for a residential building.

[0002]

2. Description of the Related Art Generally, anchor bolts are simultaneously installed on a foundation for a house when concrete is poured.
At this time, since the anchor bolts protrude from the top end surface of the formwork, when laying a curing sheet, this becomes an obstacle. For this reason, a pedestal is provided to display the curing sheet, a method of making a hole in the curing sheet, and the like are employed.

[0003]

However, in such a method, when a pedestal for mounting a curing sheet is installed, a related member of the pedestal configuration is required, and when a hole is made in the sheet to clear an anchor bolt. Rainwater enters through this hole. And once a hole is made in a sheet, it is rare that the hole can be used again. Moreover, in these methods, it is necessary to fix the curing sheet after laying it.
In order to solve this problem, the present invention provides a concrete curing method that can simultaneously raise and clamp a curing sheet with one member.

[0004]

Means for Solving the Problems In order to achieve the above object, according to the first aspect of the present invention, in order to clear the anchor bolt, the curing sheet post portion is curved to form both ends of the member. The end face has a substantially U-shaped shape that can be clamped, and the curing sheet is sandwiched inside the substantially U-shape,
It is intended to be fixed on the top end surface of the mold frame at the same time as the curing sheet by elastic force.

[0005]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an overall view of a curing sheet raising member 1, and 10 shows a curved portion of the member. In addition, shaft leg 1
Reference numeral 1 denotes an elastic force, which opens to the left and right, and fixes the curing sheet with a shaft foot 14 having a substantially U-shaped portion. Next, in order to hold the substantially U-shaped portion 15 of the mold frame, 12 and 13 are formed in a substantially U-shape.

FIG. 2 shows a view in which the member 1 is mounted on a residential basic form. The end face 17 of the anchor bolt 16 is protected by the curved portion 10 of the member 1.

FIG. 3 shows a view in which a curing sheet is laid. The curing sheet 18 placed on the end face 17 of the anchor bolt has a curved portion of the member 1 at the substantially U-shaped portion 15 of the mold 21. It is pressed and fixed to the surface of the mold 21 by the shaft foot 14 with an elastic force of 10. Next, the member 1 is fixed up and down by the shaft foot 20 of the substantially U-shaped portion 15 of the mold 21 and the shaft foot 13 of the member 1.

FIG. 4 is a view showing an example of the curing sheet raising member 2. As shown in FIG.

FIG. 5 shows a state in which the curing sheet 18 is fixed by the member 2. That is, even if the shaft foot 20 of the substantially U-shaped portion 15 of the formwork 21 and the shaft foot 24 of the member 2 are separated, the shaft foot surface 25 of the member 2 can be lengthened and the curing sheet can be fixed by surface pressure. .

FIG. 6 shows a conventional method. Curing sheet 18
In this method, the members 28 and 29 are assembled with screws 30 or the like, the curing sheet 18 is put on the sheet, and then the sheet is fixed with a magnet 26 or the like.

FIG. 7 shows a view in which holes 27 are formed in the sheet 18 and the concrete is cured with the curing sheet 18 in order to clear the anchor bolts 16. In this case, rainwater may infiltrate through the hole 27, and there is a problem in reusing the curing sheet. The curing sheet is fixed with 26 magnets.

[0013]

As described above, even if the anchor bolts become obstacles when laying the curing sheet of the basic concrete, the member of the present invention can reduce the damage of the curing sheet and increase the recycling rate. Cost can be reduced.
