Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel structure connecting structure in an industrialized house and a panel structure connecting metal piece suitable for use in this connecting structure, and more particularly to connecting a unit room with a foundation or unit rooms. The present invention relates to a panel structure connecting structure and a connecting metal article suitable for the above.

[0002]

2. Description of the Related Art In recent years, industrialization has progressed in buildings and the like.

[0003] In particular, for example, a unit construction method has been adopted in order to shorten the construction period and to facilitate on-site construction. In this unit construction method, a box-shaped unit room preassembled and produced in a factory is transported to the site, and a plurality of unit rooms are assembled at the site to build a house or the like.

[0004] Conventionally, when fixing such unit rooms on a foundation, or stacking unit rooms and connecting and fixing them vertically, an anchor bolt mounted on the foundation or a wall of a unit room downstairs. The bolts attached to the panel are pierced through the floor panel of the unit room, nuts are attached to these anchor bolts or bolts from the indoor side of the unit room, and the nuts are tightened for connection and fixing.

[0005]

In the above-mentioned conventional example, an anchor bolt arranged on a foundation or a bolt protruding from a wall panel of a unit room downstairs penetrates a floor panel of a unit room to be directly attached. Since the nut was tightened and fixed from the indoor side, the unit room to be mounted was placed and positioned on the foundation or on the unit room and projected from the anchor bolt or the wall panel of the unit room below. After inserting the bolts through the through holes formed in the floor panel, the worker must enter the unit room and perform the nut tightening work.The mounting and positioning work of the unit room and the nut tightening work must be performed. Since it has to be performed in different stages, the work is troublesome and the work time is extended accordingly. There has been a problem to say.

In order to tighten the bolts and nuts from the inside of the unit room, it is necessary to form an opening for tightening work inside the wall panel. And
The work of covering the opening and mounting the interior finishing material such as a cloth must be performed after the tightening work of the bolts and nuts is completed, and the interior finishing work on site is required. Such interior finishing work at the site was one of the obstacles to the industrialization of the panel construction method or the unit construction method.

The present invention has been made in view of the above problems, and an object thereof is to install an anchor bolt from the outside of a panel structure such as a unit room or a wall panel when installing a foundation or a unit room downstairs. Another object of the present invention is to provide a panel structure connecting structure that can be connected easily and in a short time by tightening and fixing bolts protruding from the wall panel and a connecting fitting that is preferably used for this connection.

[0008]

In order to achieve the above object, the connecting structure of the panel structure according to claim 1 is a plurality of connecting structures of a foundation or wall panel and a floor panel on the outer end face side of the floor panel. The connection hardware is fixed, and the foundation and the floor panel or the floor panel and the wall panel are connected via the connection hardware, and the connection operation is performed from the outside of the wall panel.

Further, the panel structure connecting metal article according to a second aspect has a side portion having a mounting hole for fixing to an outer end surface of the floor panel and a connecting hole for vertically inserting a bolt. It is characterized by including an upper portion and a lower portion, and a bolt tightening operation portion formed by opening at least the front surface.

[0010]

The connecting hardware is attached to a mounting member such as a floor panel with a screw or the like through a mounting hole formed in a side portion thereof.

Next, anchor bolts or bolts protruding from the wall panel are inserted into the bolt insertion connecting holes formed in the upper and lower portions.

The bolt can be easily connected by screwing a nut to the anchor bolt or the bolt by the bolt tightening operation portion formed by opening the front surface at least. Moreover, since the connecting hardware can be placed in advance at the factory shipment stage and attached to the attachment member, the work fixing at the site is omitted, and the work time can be shortened accordingly.

Further, in case of connecting the panel structure such as each panel or unit room used in the panel construction method by using the connecting hardware, the case of the unit room will be explained as an example. A plurality of connecting metal parts are fixed to predetermined positions on the outer end surface of the floor panel of the room through the mounting holes on the side parts thereof.

Next, the bolts protruding from the wall panel of the unit room are inserted into the upper connecting holes of the connecting metal article and tightened, and the bolts are conveyed to the construction site in this state.

Next, a bolt protruding from the wall panel of the foundation or another unit room to be connected is inserted into the lower connecting hole of the connecting metal fitting in alignment, and a nut is inserted into the bolt tightening operation portion from the outside of the unit room. If it is inserted, screwed into the bolt and tightened, the unit room can be aligned and connected and fixed at the same time, and the construction time can be shortened.

Further, as described above, since the panels can be connected to each other from the outside of the wall panel, the inner wall surface of the wall panel can be preliminarily subjected to interior finishing such as cloth at the factory. Efficiency can be improved.
