Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) This invention relates to construction drainage panel pieces and construction drainage panels.

(Prior art) External wall materials such as cement boards, stones, metal plates, tiles, blocks, etc. are arranged on the external walls of structures and buildings in a flat manner, and joints are provided in adjacent gaps to close the gaps. At the same time, it connects them. The gaps between the joints are filled with a resin-based sealant or a waterproof cement mixture, and the inside of the membrane prevents water from leaking into the interior of the building through the gaps. Therefore, among the conventional exterior wall materials, there is no known exterior wall material that has a drainage function in itself.

(Problems to be Solved by the Invention) In the conventional technology described above, that is, the structure of a simple exterior wall material and joints, ■ In the case of resin-based sealing materials, durability is poor and maintenance costs are high. It takes.

■ Due to aging of the sealing material, some joint breaks may occur,
This makes it extremely difficult to discover even if there is a water leak inside. Therefore, the steel frames and other materials used in the internal structure of the building will quickly corrode, resulting in a large loss in maintenance costs.

■ Cement-based sealants have no elasticity, so
When a building shakes due to an earthquake or other vibrations, cracks and cracks easily form in the joints, and water leakage from the core and weathering process accelerate the corrosion of the steel frame and other materials used in the internal structure of the building. The economic loss is large.

There were problems such as.

When this invention is used as an exterior wall material, the joints are filled, but by providing the building material (exterior wall material) itself with a drainage function, even if the joints are damaged, the interior of the building will be drained. This is a completely new development that corrects the problems of the prior art and at the same time aims to prevent water from flooding.

(Means for Solving the Problems) Next, the present invention will be explained using reference numerals in the drawings corresponding to the embodiments.

That is, in this invention, a horizontal groove frame 3 is recessed in the upper surface 2 of a rectangular base material 1, and holes 8.9.10 are formed that communicate from the bottom part 4 of the horizontal groove frame 3 to the front surface 5 and side surface 6.7 of the base material 1. A construction drainage panel piece 13 with vertical grooves 11.12 perforated on the side surfaces 6.7, and two opposing horizontal plates 15. which stand upright from the bottom plate 14.
Frontage 18.1 on both sides of long groove plate 17 with concave cross section consisting of 16
9, two opposing vertical plates 20.2 stand upright from the bottom plate 14.
1, which is inserted into the horizontal groove frame 3 of the horizontally adjacent construction drainage panel pieces 13 by straddling the opposing vertical plates 20 and 21 of the engaging tool 22, and which are adjacent in the upper direction. This is a drainage panel for construction, in which the construction drainage panel piece 13 is in contact with the upper end of the opposite horizontal plate 15,16.

(Function) The drainage panel for construction according to the present invention is constructed by filling joints into gaps that are arranged adjacent to each other in four directions: top, bottom, left, and right. At this time, the side hole ends are constructed so as to be located outside the filled joints so as not to be buried in the joints.

Joints become brittle over time in natural environments such as wind, rain, and drought, and are also damaged by earthquakes, vibrations from moving vehicles, and the like. If the damaged part is a horizontal joint, rainwater enters through the horizontal joint, flows down into the horizontal groove frame which is lowered in steps, and flows down to the front and side surfaces of the base material through the hole in the bottom. In addition, rainwater that enters through the vertical joints descends along the vertical grooves and fireproof plates, and flows down to the bottom plate of the engagement tool.Since the opposing vertical plate is inserted into the horizontal groove frame, It flows down into the interior and flows out from the front and sides of the base material along the pores.

Therefore, even if damage such as cracks or cracks occurs in the joints, rainwater will always flow out to the outside and will not enter the interior of the structure. Traces of the 111i water flow remain on the front and side surfaces, and by discovering these flow traces, damaged parts of the joints can be found. As a result, damaged parts of the joints can be quickly repaired and repaired. Furthermore, the holes act as ventilation holes, allowing moisture to be removed from the inside of the structure and allowing fresh air to be taken in from the outside, thus functioning as natural ventilation holes.

(Example 1) In the figure, 1 is a rectangular base material, which is a rectangular cement panel piece, with horizontal groove frames 3.24 recessed on its upper surface 2 and lower surface 23, and , vertical grooves 11.12 are provided on both side surfaces 6.7. In the horizontal groove frame 3 recessed in the upper surface 2, a hole 8 communicating from the bottom portion 4 to the front surface 5 below the bottom portion 4 and a hole 9.10 communicating to a portion close to the outer surface of the side surface 6.7 are bored. Ta. This hole 8
．． 9.10, it is also possible to insert a tube all the way through.

The horizontal connection of the construction drainage panel pieces constructed in this way is achieved by passing the fireproof plate 25 into the longitudinal grooves 11 and 12 of the adjacent panel pieces, as shown in FIGS. 6 to 8. At the same time, a back-up material 26 such as a synthetic resin material or a foam material is brought into contact with the fireproof board 25, and a caulking material 27 is embedded into the gap from the outside to form a joint 28. The fireproof board 25 is made of back-up material 26 and caulking material 27.
functions as a stopper. At this time, the side hole 9.
10 is located close to the outer surface, so it is not blocked by the joint 28.

In addition, the vertical connection of construction drainage panel pieces is as shown in Figures 6 to 9.
A fireproof board 29 was placed between the horizontal groove frames 3 and 3, and a back-up material 30 was placed in contact with the fireproof board 29 in the same manner as described above, and a caulking material 31 was embedded to form joints 32.

In addition, when this joint 28.32 was damaged and water was sprayed on the damaged part, the hole 8 on the front face 5 and the hole 9.1 on the side face 6.7 were found.
Although water was flowing down from 0, no water droplets were observed on the inner surface of the panel.

(Effect of the invention) According to this invention, even if the joints are damaged, rainwater from the outside will flow down to the outside again along the holes, so no rainwater will enter the back side of the panel or the inside of the building. do not. In addition, since the holes also perform the function of intake and exhaust inside the building, the useful life of the building itself is extended.

Furthermore, damage to the joints can be quickly discovered by the traces of rainwater flowing from the holes, allowing for early maintenance, and this synergistic effect with the above effects further improves the durability of the building. Note that the holes from the front of the panel have a smooth air intake and exhaust function, and also have a decorative function.
