Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a beam for supporting concrete slab forms.

The beams that support the slab formwork are deflected by the load of the concrete when concrete is placed on the floor, so in order to account for this deflection, the beams that support the slab formwork are designed to be raised in the shape of a mountain at the center. .

The present invention provides a beam for supporting slab formwork, which allows the above-mentioned bulge to be easily adjusted.

Hereinafter, embodiments of the present invention will be described based on the drawings. 1 is a beam for supporting slab formwork, and both ends are attached between the beam form side plates B and B with support A or mounting brackets, and slab formwork C is placed on top of it, and the floor concrete A beam 1 for driving D is composed of a main body 2 and side beams 3 which are extendable and retractable at both ends of the main body 2.

The main body 2 includes an upper member 4 and a lower member 5 having a rectangular cross section.
are arranged in parallel and are integrated by a reinforcing member 6, and a gap 7 is provided in the center of the lower surface of the upper member 4 in the length direction.

The side beams 3 are arranged at both ends of the main body 2 and expand and contract to adjust the length of the beam 1.
a horizontal member 10 parallel to the elastic member 8 and integrated by a reinforcing member 9;
When the elastic member 8 is loosely fitted into the upper member 4 of the main body 2, the reinforcing member 9 passes through the gap 7 of the upper member 4, and the horizontal member 10 is inserted into the lower member of the main body 2. 5, and a distance such that there is a slight gap is maintained between the horizontal member 10 and the lower member 5. Pin insertion holes 11 are drilled at appropriate intervals in the elastic material 8, and the beam 1 is aligned with the pin insertion holes 12 drilled in the upper member 4 of the main body 2 and pinned with pins 13. length.

Reference numeral 14 denotes a peeling amount adjustment part fixed to the tip of the horizontal member 10 of the side beam 3, and the metal fitting 15, which has a U-shaped cross section slightly wider than the lower member 5 of the main body 2 and is open at the bottom, is attached to the horizontal member 10 of the side beam 3. A threaded rod 15 having a head 17 is screwed into a nut 16 which is fixed to the metal fitting 10 and fixed to the upper surface of the metal fitting 15. A snap ring 21 is engaged with the peripheral edge of the hole in the plate 20, and a snap ring 21 is fitted to the tip thereof, and the stopper 19 is brought into contact with the lower member 5 of the main body 2, and the threaded rod 18 is rotated in the screwing direction. The horizontal member 10 and the lower member 5
Since there is a slight gap between them, an upward force acts on the end of the horizontal member 10, and this force acts on the elastic member 8 through the reinforcing member 9a of the horizontal member 10, and the upper member 4 and the elastic member 8 are pinned together. side beam 3 with the part as the fulcrum
is tilted, giving beam 1 a bulge.

Reference numeral 22 denotes a connecting fitting for preventing steady rest, which is fitted to the lower member 5 of the main body 2 and the horizontal member 10 to connect the lower member 5.
It is pinned to the end of the

The method of using the beam 1 of the present invention is to expand and contract the side beams 3 at both ends of the main body 2 to adjust it to the width of the floor concrete D to be poured, and to connect the pin insertion hole 12 of the upper member 4 of the main body 2 to the side The pin 13 is inserted in alignment with the pin insertion hole 11 of the elastic member 8 of the beam 3. Next, the threaded rod 18 of the peeling amount adjustment part 13 is rotated to tilt the side beam 3 using the pin 13 that pivots the upper member 4 of the main body 2 and the elastic member 8 of the side beam 3 as a fulcrum to adjust the peeling. After doing this, it is erected between the pillars A and A.

As described above, the beam 1 of the present invention has the practical advantage of being able to easily adjust the tilt because the inclination of the side beam 3 can be adjusted by rotating the threaded rod 18 of the tilt adjustment section 14.

Claims (1)

[Scope of utility model registration request] A main body in which an upper member and a lower member are parallel to each other and a reinforcing material is disposed between both members to form an integral body; A side beam is formed by a horizontal member positioned above the lower member with a slight gap, and a side beam is fitted to the lower member and the horizontal member at both ends of the lower member of the main body to pivot the steady rest metal fitting. At the same time, a metal fitting with a U-shaped cross section and an open bottom is fixed to the tip of the horizontal member, and a metal fitting pivoted to the tip of a threaded rod screwed into a nut fixed to the top surface of the metal fitting is attached to the bottom of the main body. When the threaded rod is brought into contact with the member and rotated in the screwing direction, an upward force will be applied to the reinforcing member fixed to the horizontal member, and this force will cause the pinned part that pivots the upper member of the main body and the elastic member to A beam for supporting slab formwork, characterized in that the side beam is configured to be inclined as a fulcrum.
