Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of attaching a drainage collection device installed on a rooftop or the like of a building to collect and drain rainwater accumulated on the rooftop of a building or the like.

Conventionally, the method of installing a drainage collection device on a rooftop to drain rainwater that collects on the roof of a building, etc. is to mark the installation location of the drainage equipment on the concrete floor of the rooftop using a chisel, hammer, etc. Four funnel-shaped parts slightly larger than the external shape of the drainage tool were carved, and the drainage collection equipment was housed in the recesses, and cement mortar was filled around the recess to install it.

However, carving a recess in a concrete floor is not only an extremely difficult task, but also prevents the correct installation of drainage equipment, and can lead to unnecessary floor damage or cracks. Such damage may occur, and repair work is required to repair these damages, which is a disadvantage in that time and labor are inevitably wasted.

In order to eliminate these drawbacks, the present invention provides a drainage and draining device that is easy to work with, can be installed accurately, and can be installed quickly and efficiently without causing unnecessary damage to the floor. The purpose of this method is to provide a method for installing the drainage and drainage equipment, using a substitute mold with a shape slightly larger than the external shape of the main body of the drainage and drainage equipment. Appropriate recesses are formed using the substitute mold at the locations where the water collection device is to be installed, and the main body of the drainage device is accommodated in the four parts.
This installation method is characterized by filling the surrounding area with cement mortar.

Next, one embodiment of the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes the main body of the water collection device, which is formed of a thin metal plate into an almost funnel shape, with a cup-shaped receiver formed on the upper part and a pipe section 6 connected to the lower part of S2. ing.

Reference numeral 4 denotes a substitute mold formed in a shape similar to that of the main body 1, which is made of wood or plastic and is shaped like a toy top. A cylindrical lower body 6 is vertically provided.

Note that a plurality of scale lines 7 are written on the peripheral side of the lower body 6, and the scale lines 7 written at positions where the height H from the top surface reaches, for example, 100 mm IJ are marked with the number 100, Also, the scale line 7 written at the position reaching 110 mm has 11
A number 0 is written on each scale line 7, and a number representing its height is written on each scale line 7.

The shape of the upper body 5 of the substitute type 4 is almost similar to the shape of the receiving part 2 of the main body 1 of the water collection device, but its outer shape is slightly larger, and the diameter of the lower body 6 is , is approximately the same diameter as the tube part B of the main body 1, but its length is formed slightly longer. Therefore, the height of the substitute mold 4 is formed to be slightly higher than the height of the main body 1. Note that FIG. 2 is a drawing comparing the external sizes of the main body 1 and the proxy mold 4, and as shown by diagonal lines, the proxy mold 4 is formed larger around the upper part and at the lower end. Note that the difference 1:6 in the upper half is an appropriate volume for filling with cement mortar.

Reference numeral 8 indicates a bolt insertion hole extending vertically through the center of the substitute mold 4, 9 indicates a concrete floor wall on the roof of the building, and 10 indicates a hole for inserting a bolt when pouring the floor wall 9. The frame plate used is shown. Furthermore, 11 indicates a bolt for attaching the substitute type 4, 12 indicates a nut, and 16 indicates a washer.

Next, a method of installing the water collection and drainage device of this example will be explained. When pouring the floor wall 9 on the roof of the building where the drainage and drainage equipment is to be installed, first set the substitute mold 4 so that the height of the substitute mold 4 is approximately equal to the thickness of the floor wall 9 to be installed. Cut the bottom edge. In this case, the height of the lower body 6 of the surrogate mold 4 can be judged from the scale [7] and the cutting position can be known. Next, as shown in FIG. 4, a hole for inserting the port 11 is made through the frame plate 10 corresponding to the lower surface of the floor wall 9 at the position where the main body 1 of the water collection device is attached, and the substitute mold 4 is inserted at that position. Then, a mounting bolt 11 is inserted through the hole in the frame plate 10 into the center hole 8 of the substitute mold 4, a washer 13 is inserted into the bolt 11 projecting upward, and the nut 12 is used to tighten the bolt 11.

In this state, concrete is poured onto the frame board 10 and the floor wall 9 is poured, but since the height of the substitute mold 4 is approximately equal to the thickness of the floor wall 9 to be poured, The horizontal positions of the upper surface of the installed floor wall 9 and the upper surface of the substitute mold 4 are approximately equal. After the poured floor wall 9 is almost dry, bolt 11
And when the frame plate 10 is removed and the substitute mold 4 is removed,
Four parts 14 having the same shape as the surrogate mold 4 are recessed in the floor wall 9, and a circular hole 15 is penetrated through the lower center of the four parts 14.

Next, the pipe portion 6 of the main body 1 of the water collection device is inserted into the circular hole 15 provided through the floor wall 9, and the main body 1 is installed so that the upper surface of the main body 1 is approximately equal to the upper surface of the floor wall 9. In this case, since the inner diameter of the circular hole 15 is approximately equal to the outer diameter of the tube portion 3, the surrogate mold 4 is fixed upright and will not fall or fall. In this case, the parts to be attached to the main body 1 may remain attached. Therefore, if the gap formed between the main body 1 and the floor wall 9 is filled with cement mortar, the main body 1
can be installed. In this case, since the pipe portion 6 of the main body 1 is tightly inserted into the circular hole 15, the cement mortar can be properly filled without flowing downward. Further, the main body 1 can also be mounted while maintaining an accurate vertical position.

By attaching parts such as the dustproof cap 16 to the main body 1 mounted in this manner, the water collection and drainage device can be completed.

Note that the surface of the floor wall 9 may be treated with waterproof mortar or the like.

Furthermore, the surrogate mold used in the present invention may be made of an appropriate material such as wood, plastic, or plaster.

As described above, according to the mounting method of the present invention, [! By inserting the lower part of the water collection device into the hole at the bottom of the cap, the main body can be fixed upright, and a gap suitable for filling with cement mortar is created around the upper part of the main body. The main body can be mounted by filling the @ part with cement mortar, which makes the work simple and allows quick and accurate mounting. Another advantage is that the floor and walls are not damaged or damaged, and therefore no repair work is required.

In addition, the substitute mold used in the method of the present invention is formed longer than the main body, and the lower part is cut according to the thickness of the floor wall, so the same substitute mold can be used. It has the advantage that it can be used on floor walls of various thicknesses.
