[Detailed Description of the Invention] (Field of Industrial Application) The present invention is directed to the construction of concrete slabs using a combination of supports, beams, and formwork sheathing plates, in which the beams and sheathing plates are removed while leaving the supports in place during demolding. This article relates to shoring and shoring methods for slab concrete formwork that make it possible to do this.

(Conventional technology) Conventionally, when constructing slab concrete,
We erected the daihiki, joists, and support beams between the erected pillars,
A plywood shelving board is placed on top of it to create the formwork. However, this construction method has the disadvantage that it is troublesome to assemble and dismantle the formwork, and the rotation rate of the formwork is low. Therefore, as shown in Fig. 1O, a support blade 28 is provided on a support column 26 having a top plate 27 at its upper end so that it can be raised and lowered, and this support blade 28 is made to support a large drawer 29, a joist 30, or a support beam. Formwork shoring has come into use.

(Problems to be Solved by the Invention) The above-mentioned shoring system has the advantage of being able to quickly remove the main drawers 29 and joists 30 while keeping the pillars 26 upright, improving the rotation rate of members. , the weir plate 31 on the column 26 cannot be removed until the column 26 is removed, and the column 26 cannot be removed until the column 26 is removed.
There is a problem in that when removing the weir plate 6, a scaffold is required to remove the weir plate 31 thereon.

Recently, as described in Japanese Patent Application Laid-Open No. 61-78958, it has been proposed to support a beam on a drop jack (support for the head of the column) provided on the column, and to erect a stile panel on the beam. =3- However, in the case of using frame panels as in this invention, not only are they very expensive, but the frame panels are formed to a fixed length, so there is a possibility that there will be excess or deficiency in the fitting. There are many cases where this is the case, and the problem is that it becomes extremely troublesome to create a framework for the excess or deficiency.

(Effects of the Invention) As explained above, according to the present invention, a large pull beam is constructed between the drop jacks provided on the columns arranged in a row, and a supporting beam is installed between the opposing large pull beams. , erect support beams with beams attached to the upper surface between the drop jacks of opposing supports, and lay sheir plates on these support beams separately from the top plate of the support support and the top surface of the main rod of the main beam. Because of this structure, it is possible to dismantle and remove the sheir plates, large draw beams, and shoring beams while the pillars remain erected, and to reuse them, increasing the reusability of the formwork. Formwork and shoring can be assembled and dismantled easily and efficiently. In addition, since we use plywood and other widely used weir boards as formwork boards, not only is the formwork cost low, but it can be applied to a wide range of construction projects without being restricted by the shape or area of the slab. It has many excellent effects such as:
