Description

[Detailed explanation of the invention] This invention relates to a structure for draining water leakage from the back of the stone cladding on the exterior wall, and is intended to prevent damage by making the stone cladding on the wall earthquake resistant. It's about structure.

In general, the exterior wall stone cladding structure is constructed using the dry method in order to improve earthquake resistance and streamline construction, but the lower part of the exterior wall is lined with backing to prevent damage to the stone due to vibrations and impacts from cars and other objects. It was hoped that wet construction methods such as concrete mortar would be used.

However, according to the above-mentioned wet construction method, if water leaks between the concrete wall and the back surface of the stone wall and a puddle forms on the upper surface of the mortar at the bottom, or if the mortar becomes wet, the stone wall may leak. Dirt on the adhesive surface,
There were problems with staining, discoloration, and cracks and damage to the stone plastering due to winter freezing.

This idea was made to solve the above-mentioned problems in the wet construction method, including solving the difficulty of handling the water gradient on the top surface of back-filling mortar for long walls. To provide a drainage structure on the back side of an exterior wall stone cladding, which naturally and easily drains water between the claddings.

Hereinafter, one embodiment of this invention will be described in detail based on the attached drawings. In Figure 1, 1
The outer wall is covered with stone, and is installed with a predetermined gap 3 between it and the concrete wall 2. The upper part of the concrete wall 2 is constructed by a dry construction method, and the lower part by a wet construction method in order to prevent cracks and damage to the outer wall masonry 1.

When pouring mortar 4 to a predetermined height in the gap 3 between the exterior wall masonry 1 and the concrete wall 2, the mortar 4 is placed at regular intervals in the longitudinal direction along the concrete wall 2. , a drainage pipe 5 is buried that reaches the upper surface of the mortar 4 from the ground surface. The drainage pipe 5 has a pipe body 5a made of a perforated vinyl chloride pipe, and a permeable paper 5b such as Japanese paper that prevents mortar from entering and absorbs only water through capillary action is wrapped around the outer periphery of the pipe body 5a. The protective material 5c is formed by winding a thread in a net shape or by wrapping a mesh cloth in order to protect the protective material 5c.

Therefore, a drainage pipe 5 was installed in the gap 3 between the exterior wall stone cladding 1 and the concrete wall 2, and a backing mortar 4 was placed, so that rainwater could see through the joints of the exterior wall stone cladding 1 and enter the gap 3. The seeping water is discharged from the backing mortar 4 to the lower ground through the hole of the drainage pipe 5.

As explained in detail above, the drainage structure on the back of the exterior wall stone wall according to this invention is extremely easy to construct, and also allows leakage water that seeps through the stone to be absorbed into the drainage pipe within the mortar. Because it can be drained, there will be no stains, dirt, or discoloration on the surface of the exterior stone wall due to water leakage.
Additionally, there are no longer any cracks or damage to the stone walls on the exterior walls due to winter freezing.

In addition, there is no need to install special processing or parts such as a drain port on the top end of the pipe, unlike conventional drain pipes that are buried in mortar. Since it can be drained naturally, the practical effects are extremely significant, such as ease of wastewater treatment due to differences in water gradients.

Claims (1)

[Scope of utility model registration request] Drainage pipes reaching from the ground to the upper surface of the mortar are buried at approximately regular intervals in the longitudinal direction of the back mortar in the back mortar cast in the lower part of the gap between the outer wall stone paving and the concrete wall that make up the wall. ,
The drainage pipe is characterized in that a permeable paper such as Japanese paper is wrapped around the outer periphery of the perforated vinyl chloride pipe body, and a thread is further wrapped around the outer periphery of the permeable paper in a net shape, or a mesh cloth is wrapped around it as a protective material. Drainage structure on the back of the stone-clad exterior wall.
