取付用に使用可能な係止具に関するものである。[Detailed explanation of the invention] (Industrial application field) This invention was developed by assembling reinforcing reinforcing reinforcing bars into a cage shape and placing them inside the formwork when manufacturing plates for steam-cured lightweight aerated concrete (hereinafter referred to as ALC). The present invention relates to a support that doubles as a spacer for reinforcing reinforcing bar mats used for horizontal and accurate placement, and also to a locking tool that can be used to attach ALC plates.

ている。(Prior art) Generally, when manufacturing thick ALC plates, two or more lattice-shaped reinforcing bars are welded with auxiliary bars orthogonal to the longitudinal main bars, and two or more reinforcing bars are separately made. Using spacers welded in the shape of a grid, weld them into a cage shape so as to maintain the desired spacing, or assemble them into a cage shape by attaching them with plastic spacers. When the reinforcing bar mats are arranged vertically within the ALC manufacturing formwork, they are set in predetermined positions using set pins or the like. Next, a raw material prepared by adding additives such as metal aluminum powder to a slurry mainly composed of siliceous raw materials and calcareous raw materials is injected into the mold and foamed. Then, when it is allowed to stand still for an appropriate period of time to reach a semi-hardened state, the set pin and mold are removed, and the rectangular semi-plastic molded product is cut into a predetermined size. The product is then cured with high-temperature, high-pressure steam in an autoclave.

The structure is such that it is supported by the bottom plate of the formwork 14 via a spacer 13 attached to it, and is set in a predetermined position by regulating horizontal displacement with set bolts (not shown). Note that 15 indicates a bridge and 16 indicates a reinforcing bar.

ーサとは別個に使用されるものである。 In addition, there are structures in which a locking device is buried and fixed after the ALC plate material is commercialized as a locking device for attaching the ALC plate material, and a structure in which the locking device is fixed to reinforcing bars during the manufacture of the plate material and then the ALC manufacturing raw material is used. Various structures have been proposed in which the reinforcing rods are buried in a cage. It is used separately from the spacer that is assembled.

余分にかゝる等の欠点があつた。(Problem that the invention aims to solve) However, the conventional spacer for forming the reinforcing bar mat into a cage shape is used exclusively for forming the cage shape, and after it becomes an ALC plate material, it is used specially. However, it was difficult to attach the spacer. Furthermore, in order to lift and attach the ALC plate material, it is necessary to attach an embedded metal fitting separately from the spacer as necessary, which has disadvantages such as additional cost and labor.

や移動用吊金具としても使用できるものである。 Therefore, this idea can be applied to the production of wide ALC plates that cannot be obtained by vertical casting, in which the reinforcing bars are arranged horizontally within the formwork, and the reinforcing bars are arranged vertically. It provides a locking device for reinforcing reinforcing bars inside the formwork that doubles as an effective spacer, and can also be used as a locking device for attaching the ALC plate material that has become a product, and a hanging device for moving it. be.

The reinforcing bar mats can be easily assembled into a cage shape within the formwork without having to assemble multiple reinforcing bar mats arranged in the same plate into a cage shape using spacers in advance, and then the upper formwork can be assembled into a cage shape. The reinforcing bar mat can be tensioned horizontally using a fastener from the outside through the through hole provided in the frame, allowing the reinforcing bar mat to be placed inside the formwork with high dimensional accuracy. There is no hole left for removing the set pin that was used for this purpose.
