Description

TECHNICAL FIELD The present invention relates to a wooden panel assembling apparatus, and more particularly to a rectangular panel body in which face plates are attached to both sides of a square frame body. The present invention relates to a hydraulic system that supplies pressure oil from a hydraulic supply means of a circulation mechanism that circulates the support frame to a hydraulically driven movable ruler of the support frame that is joined and compressed in the direction.

"Prior art" One of the methods for constructing a detached prefabricated house is to use a rectangular wooden panel (panel body) made by attaching face plates to both sides of a frame body in which a frame material (core material) is assembled in a square frame shape. make use of,
There are ways to assemble floors, walls, etc.

This construction method is, for example, the method shown in FIGS. 22 to 25. That is, as shown in FIG.
The unitized floor panel 2 is laid on the concrete foundation 1 constructed on site, and the wall panels 3 on the first and second floors are assembled on it as shown in FIGS. 23 and 24.
Furthermore, a method of constructing a building by assembling a roof panel 4 as shown in FIG. 25 by forming a frame, a tree, etc.

The above-mentioned panels (floor panel 2, wall panel 3, etc.) are
The floor panel 2 is integrated with an adhesive and a screw nail, and the floor panel 2 is laid on the adjustment mortar adjusted on the upper surface of the foundation 1 (a cloth foundation in the illustrated example) via a base wheel, and the floor panel 2 Each wall panel 3 is integrated with the foundation by dropping a hole at the lower end of the wall panel into an anchor bolt protruding from the upper surface of the concrete foundation and tightening the bolt.

By the way, in such a method of constructing a house, the work of joining the wall panels is usually performed by a work of firmly joining the wall panels using a panel tightening device called a shimerer. This work involves sandwiching a plurality of wall panels raised on the floor with a pair of left and right support members connected by a single wire, and operating a wire winding device attached to one of the support members, Although it is carried out by winding a wire, in recent years, with the progress of industrialization in the construction work, a construction work of previously assembling a wall panel or the like with a large wooden panel has been required.

"Problems to be solved by the invention" However, at present, it is difficult to improve the quality of a large wooden panel because it is a manual work even if it is carried out in a factory. There was a problem to be solved.

Therefore, the inventors of the present invention have conducted diligent research to solve such problems, and as a result, mount a plurality of rectangular panel bodies each having a face plate attached to both sides of a rectangular frame body. In the base part to be joined in the plane direction, sandwiching these panel bodies between the fixed ruler and the movable ruler of the base part, the entire panel body is subjected to a constant curing period (adhesive by a pressure applied by the movable ruler). It came to the idea that it is possible to easily manufacture a large wooden panel in a factory or the like by using a support frame that is compressed.

Further, in order to promote automation, such a movable ruler of the support frame is hydraulically driven, and the movable ruler is circulated on a clamping and decompression line for clamping or decompressing the movable ruler with the supporting frame lying down. Then, they came to the idea that wooden panels could be manufactured more easily.

However, at present, an effective and appropriate device for assembling such a wooden panel has not been developed, and when joining a plurality of panel bodies with such a device, the following is performed. There are still some issues to be solved.

That is, when the hydraulic pressure supply means for supplying the pressure oil to the hydraulically driven movable ruler is provided outside the support frame, the support frame circulates through the clamping and depressurizing lines, so that wiring, piping, etc. are provided on the support frame. Is difficult to connect,

It is difficult to use the hydraulic coupling device, and there is a problem that the piping must be manually connected.

In addition, it is difficult to provide the support frame with the hydraulic pressure supply means, the power source thereof, and the like, which leads to an increase in the size of the support frame and an increase in the cost of circulating the support frame on the compression and decompression line. It is a point.
