Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention is suitable for constructing industrialized housing, such as prefabricated housing, where the framework of the building is formed by joining wooden panels as -1 mode. This is an anchor bolt positioning plate that is applied to an anchor bolt positioning plate that is installed at a protruding corner position of a foundation or at a position intersecting a T-shape, and positions and holds the anchor bolt in an upright state. .

``Conventional technology'' One of the methods of planning for industrialized housing is a method that mainly uses grid planning according to basic modules.

The purpose of this illegal method is to plan as freely as possible while keeping the dimensions and types of all parts, including the exterior walls and spare parts, as small as possible, but the basic modules vary depending on the system, and the grid Similarly, there are various ways of thinking about how to fit the parts into the space (for example, see Japanese Patent Publication No. 1-12890).

In the past, one of the housing construction methods that promoted industrialization based on this basic module was to create rectangular wooden panels made by attaching face plates to both sides of a square frame made of frame materials (core materials). There is a method of using it to assemble floors, walls, etc.

This construction method involves, for example, laying unitized wooden floor panels on a concrete foundation built on-site, and assembling wooden wall panels for the first and second floors (hereinafter referred to as wall panels) on top of them, and then This method involves constructing a building by assembling frames, timber, etc., and assembling roof panels.

Each of the panels (floor panel, wall panel, etc.) is integrated with adhesive and screw nails, and the floor panel is mounted on a mortar adjusted to the top surface of the foundation (fabric foundation in the illustrated example). At the same time, each wall panel on the first floor is integrated with the foundation by inserting the hole (bolt insertion hole) at the bottom end of the wall panel into the anchor bolt that protrudes from the top of the concrete foundation and tightening the bolt. It is now possible to do so.

By the way, in the construction method of such a house, in the construction of anchor bolts, conventionally, the anchor bolt embedding position is set with a certain interval between each module core based on the intersection position between the module cores. In some cases, workers manually push in anchor bolts to secure the concrete in place before the concrete poured into the foundation formwork hardens.

[Problem to be solved by the invention] However, in the construction of anchor bolts using such conventional technology, workers manually push the anchor bolts into place before the concrete cast in the foundation formwork hardens. Because the anchor bolt positioning accuracy is poor because of the method used, and because it is done manually, the anchor bolt cannot be installed due to the viscosity on the module core, which reduces the work efficiency when installing the anchor bolt. However, there were still issues to be resolved, such as the worsening of

The present invention has been proposed in view of the above circumstances, and its purpose is to improve the positioning accuracy of anchor bolts to be embedded in the foundation, and to facilitate the work of embedding anchor bolts. An object of the present invention is to provide an anchor bolt positioning plate that can achieve industrialization of foundation construction work.

[Means for Solving the Problems] In order to achieve the above object, the present invention allocates walls according to a grid according to a basic module, and uses wooden wall panels for the walls thus allocated.

It is characterized in that a plurality of tongue pieces are formed in line along the periphery of the insertion hole to elastically contact the outer periphery of the anchor bolt and hold the anchor bolt in an upright state.

"Action J: After pouring concrete into the formwork for forming the foundation, place an anchor bolt positioning plate on the top of the concrete of the L-shaped or T-shaped foundation, and insert the anchor bolts before the concrete hardens. Insert the anchor bolt into the foundation through the hole.

The anchor bolt inserted into the anchor bolt insertion hole of the positioning plate is elastically supported by a plurality of tongue pieces formed in the insertion hole of the plate body, and is supported without tilting on the foundation.

In addition, the plate body is formed in an L-shape or T-shape with the same width as the foundation, and the anchor bolt insertion holes formed in the plate body are formed along the module core. By simply installing the plate body into the formwork of the foundation and passing the anchor bolt through the insertion hole, it becomes possible to install the anchor bolt into the foundation with high precision.
