Description

[Detailed explanation of the invention] (A) Industrial field of application This invention is a workpiece for the cutting of control panel (plywood veneer), which is often used for the foundation concrete of architectural houses and concrete formwork related to civil engineering and construction.
(It is also possible to discount building materials when constructing general houses) and is extremely practical and economical, having been devised and developed with the aim of making it easier to carry out work with far greater precision and efficiency than before. It is a unique utility model.

(B) Conventional technology Conventionally, panel cutting work has been carried out using a special, relatively large circular saw, but because this circular saw is large, it can easily be used on passenger cars, etc. Considering that they cannot be loaded and transported and are relatively expensive, they are not suitable for small and medium-sized construction companies, carpenter shops, etc.

Therefore, there has been a strong demand within the industry for a new product that is lightweight, compact, and reasonably priced to replace this product, which is not commonly used and is not commonly used.

Currently, at construction sites, when cutting a control panel, both sides are measured using a scale, marked and drawn with an ink pot, and the formwork is assembled by cutting along the line with a circular saw. However, this method was very time consuming and inefficient, making it difficult for even trained professionals to cut the pieces neatly in a straight line.

(C) Problems that the invention attempts to solve However, in order to eliminate the drawbacks of the conventional work methods as explained above, the invention was developed through various trial and error experiments based on many years of practical experience at construction sites. Through repeated improvements, we succeeded in developing it based on a lightweight and compact design policy that allows anyone to easily handle it and easily load it onto a passenger car or other vehicle and bring it to the site.We are now offering this inexpensive and convenient product to the market. It's something you get.

(D) Means to solve the problem Now, the configuration will be explained with reference to the attached drawings.
First of all, in order to implement this proposal at the work site, the first step is to install the talukis 17, 18, 19, 20, etc. as the lower base of the control panel perpendicular to the control panel, and then install the Taruki 1 mentioned above
7, 18, 19, 20, etc., are installed in positions perpendicular to them. As shown in the detailed drawings in FIG. 7, an arm support base 1 is provided on one side of the talukis 17 and 20, and the arm support base 1 is shaped like a mold.
An arm support leg 25' having a stopper 25 is provided on the upper surface of the arm support base 1, and the end of the arm 2 is attached from the upper part of the arm support leg 25' in a hakama state. With the arm connecting portion 4 formed in
5', the arm 2 can freely rotate due to the support pin 26. Therefore, the arm 2 is connected to the support pin 26.
It becomes a movable mechanism centered around the fulcrum part of.

Further, the other end of the arm 2 is configured with a circular saw ruler gripping tool 3 having a shape.

Furthermore, a spring hanging piece 8 is attached to the intermediate position of the arm 2.
A stopper 4' is formed inside the arm connecting portion 4. Further, a spring hook 7 is provided on the upper edge of the arm support base 1, and a tension spring 9 is used to interpose and connect the spring hook 8 and the spring hook 7. Next, the arm support base 1 mentioned above
Female screws 5' and 6' are provided protruding from the side surfaces of the screws, and the tips of the tightening screws 5 and 6 that are screwed into these have central small holes 23' in their centers, as shown in the example in Figure 3. A rounded presser washer 23 is attached to the tip of each tightening screw 5, 6 inside the arm support base 1. In this way, attach the taluki presser washer 23 to the tip of each tightening screw.
The same applies to the tightening screws 12 and 13 that are screwed into female screws 12' and 13' that protrude from the side surface of the circular saw ruler gripper 3. Next, control panel stopper 1 determines the cutting width of the control panel.
Let me explain about 0. The form is shaped like a control panel 10' is formed in the center of the end face, female threads 11' are provided protruding from each side, and the tip 24 of the tightening screw 11 screwed into the female thread 11' is for the control panel. It is fitted inside the stopper 10 into the center small hole 23' of the diaphragm presser washer 23.

(E) Effects of the invention Next, we will explain how to use this invention in the field and its effects. First of all, as shown in Figure 2, use the taruki 17, 18, and 1 as the base of the control panel to be cut out as shown in the illustration.
9, 20 and the brackets 16, 16', etc., are appropriately positioned and arranged on the lower part thereof, and the arm support base 1 is set and fixed as a set of two on one part of the brackets 17, 20, respectively.

Of course, in this case, the circular saw ruler holder 3 at the tip of each arm 2 is used to grip and secure the circular saw ruler 14, which is accurately straight and has no bends. Once the above setup is completed, the arm 2 is lowered once as shown in FIG. 1, and the circular saw ruler 14 is set on the upper surface of the control panel 15 in a pattern. However, when looking at the surface plate 22 of the circular saw 21 in contact with the outer edge line of the circular saw ruler 14,
The control panel is positioned so that the rotary blade of the circular saw 21 is aligned with the desired cutting line of the control panel. Once the positioning is determined, as shown in FIG.
Each control panel stopper 10 is fixed by tightening the screws 11 onto the dials 17 and 20 so that they are in contact with each other. By carrying out the work setup as described above, the control panel 15 will be fixed and stably set on the taruki, and the position of the control panel will be completely prevented even during the cutting operation with the circular saw 21. Next, it is finally time to set the circular saw 21. By pushing the energized circular saw 21 at a constant speed while pressing the board 22 against the outer edge line of the circular saw ruler 14, the desired beautiful straight line cut is made and the desired purpose is achieved. When operating the circular saw 21, special attention should be paid to the fact that the cutting depth of the rotary blade must be adjusted so that the rotary blade cuts only the thickness of the control panel 15 and does not cut into the taluki material. The manner in which the arm 2 moves up and down through the free rotation of the arm 2 due to the mutual connection between the connecting portion 4 of the arm 2 and the arm support leg 25', which is a feature of the present invention, will now be analyzed and explained as follows. Now, if the arm 2 is pushed down from the horizontal level, the circular saw ruler gripping tool 3 will come into strong contact with the control panel due to the tension effect of the tension spring 9. Conversely, if the arm 2 is lifted above the horizontal level, the circular saw ruler gripping tool 3 will come into strong contact with the control panel. , Similarly, due to the tension effect of the tension spring 9, the arm 2 moves up in a light manner into the state shown in FIG.
The structure is such that the upward movement of the arm 2 is completely blocked as it comes into contact with the .

As explained above in detail, although the purpose and effect of this project are extremely large, the structure of the aircraft is light and compact to the minimum, so it can be easily transported to any site and is simple. Because it is an economical product that can be assembled and carried out quickly and is not found in other products, it is a highly needed utility model product that can fully meet the strong expectations and wide-ranging needs of not only the construction industry but also site workers. be.
