[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diagonal measuring device and a diagonal measuring method for a frame particularly suitable for panels such as a wall panel and a floor panel of a two-by-four building.

[0002]

2. Description of the Related Art A two-by-four building is disclosed in
In general, as in the invention described in Japanese Patent No. 260942, a wall panel is erected and fixed on a floor panel. A panel such as a floor panel or a wall panel has a frame formed by joining a pair of vertical frame members and a pair of horizontal frame members.

[0003] By the way, since the frame used for such a panel is required to have accuracy in dimensions and shape, the dimensions and shape are measured and corrected before use.
By the way, if a pair of corners at diagonal positions of a rectangle are both right angles, it is possible to prove that the remaining pair of corners are also right angles, and that the rectangle is a rectangle or a square. Taking advantage of this, conventionally, the shape of the framework has been measured by the following method.

That is, first, a frame is placed horizontally on a table, and one vertical frame member of the frame is brought into contact with a vertical member support plate, and the other horizontal frame member is brought into contact with a horizontal member support plate. Contact
A pair of vertical frame member pressing means provided at a position facing the vertical frame member supporting plate presses the frame set against the vertical frame member supporting plate, and is provided at a position facing the horizontal frame member supporting plate. The pair of horizontal frame material pressing means presses the frame against the horizontal frame material support plate, and the corners of the frame disposed at the contact points between the vertical frame material support plate and the horizontal frame material support plate are maintained at a right angle. Then, the driving amount of the horizontal frame material pressing means is detected by a sensor provided in each horizontal frame material pressing means. The vertical frame material pressing means is provided at positions corresponding to both ends of the vertical frame material, and the horizontal frame material pressing means is provided at positions corresponding to both ends of the horizontal frame material. Is provided on each pressing member. Then, based on the driving amount, the corners of the framework at the contact position of the vertical frame material support plate and the horizontal frame material support plate, and calculate the diagonal length between the corners at the opposing positions, The error (diagonal difference) is calculated by comparing the length of the diagonal with the theoretical value.

Hereinafter, a method of calculating the diagonal difference of the framework will be described with reference to FIG. In the drawing, reference numeral 10 denotes a theoretical framework having a diagonal difference of 0, reference numeral 20 denotes a defective framework having a diagonal difference, reference numeral 30 denotes a vertical frame support plate, reference numeral 40 denotes a horizontal frame support plate, and reference numeral 50 denotes a pressing means. That is, the length of the vertical frame material provided along the vertical frame material support plate 30 is A, the length of the horizontal frame material provided along the horizontal frame material support plate 40 is B, and the driving of the pressing means is performed. Quantity C ₁
(In the case of a theoretical framework) and C ₂ (in the case of a defective framework), the lengths α, β ₁ , and β ₂ of the diagonal lines can be calculated by the following equation according to the Pythagorean theorem.

In the case of the theoretical framework: (A ² + B ² ) ^1/2 = α = β _{1 In} the case of the defective framework: ((A + C ₁ -C ₂ ) ² + B ² ) ^1/2
= Β ₂ That is, β ₂ -α is the diagonal difference X.

[0007]

However, in such a conventional frame diagonal measuring device, as shown in FIG. 5, a pressing means is provided for each type of the framework so as to be able to handle a plurality of types of frameworks. Since they were provided at corresponding positions, assuming that the number of varieties of the framework is n, the number of necessary pressing means (the same as the number of sensors) y was 3n + 1. In other words, every time one kind of product can be increased, the number of pressing means and sensors must be increased by three each, and a large number of pressing means and sensors are required in order to correspond to a framework of many kinds. There has been a problem that the cost of the apparatus itself becomes very high. In FIG. 5, the position where the pressing means and the sensor are provided is indicated by 〇, and the pressing direction of the pressing means is indicated by an arrow in 〇. The relationship between the number y of the pressing means and the number n of the types of the framework (y = 3n + 1) is as follows.
FIG. 3 shows a graph.

An object of the present invention is to provide a framework diagonal measuring apparatus which can reduce the number of parts and reduce the cost, focusing on the above problems.
