Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to buildings having exterior walls made of concrete, tiles, concrete blocks, ceramic siding, etc.
In houses, etc., the exterior walls may crack due to aging, including freezing and thawing, alkali reactions in aggregates, and salt damage, or can be used as a base material for new exterior walls without destroying existing exterior walls that are heavily contaminated with mold, etc. This relates to a structure in which existing concrete walls, etc., were repaired by constructing.

[Conventional technology]

The exterior walls of buildings of this type are cranked every 5 to 10 years, and in order to stop this progression and to make the exterior look impressive, for example, Japanese Patent Laid-Open No. 58-164857, Utility Model Laid-Open No. 59
-1) Publication No. 7752 is known. In other words, in the former case, an asbestos seat plate is interposed between the existing exterior wall and the L-shaped new exterior material mounting bracket in the curtain oar, so that the unevenness of the existing exterior wall does not adversely affect the installation of the mounting bracket. The latter is a method for renovating the exterior wall of a building, in which a notch is provided in the existing exterior wall, and a steel liner is interposed in this cavity to fix the mounting material for installing the new exterior wall material.

[Problem that the invention seeks to solve]

However, the former new exterior wall material mounting brackets lack stability because they are arranged and supported at regular intervals only from one side of the C-shaped steel, and the joint metal fittings must be fixed to the C-shaped steel to install the new exterior wall material. Moreover, there was a drawback that the outer wall had no added heat insulation properties at all. Furthermore, in the latter case, forming a notch in an existing wall is a very difficult task and is therefore impractical.

[Means for solving problems]

In order to eliminate these drawbacks, the present invention has a C-shaped channel shape that is lighter in weight than the cross-section of a square vibrator, so that it can be easily and stably attached to an existing wall without reducing strength, and can be fixed in fewer places. We created a structure with staggered mounting force, fixed it to the existing exterior wall using fixing devices, and installed metal siding material on the ring edge to form a new exterior wall that is beautiful and does not cause cracks. This project proposes a repair structure for existing concrete walls, etc.

〔Example〕

EMBODIMENT OF THE INVENTION Below, one Example of the repair structure of existing concrete walls etc. which concerns on this invention is demonstrated in detail using drawing. 1st
The figure is a perspective view showing a case where the repair structure of an existing concrete wall, etc. according to the present invention is applied to a building, where 1 is an existing building, 2 is an existing rosette, 3 is an existing outer wall, 4 is a Kasagi fixture, and 5 is a Kasagi , 6 is a trunk edge, 7 is a mounting leg, 8 is a mounting hole, 9 is an anchor bolt, 10 is a nut, 1) to 15 are accessories, 16 is a metal siding material, and 17 is a fixing tool such as a nail.

To explain further, existing building 1 is made of concrete and ALC.
It consists of square, gable, flat roofs, etc. made of blocks, tiles, and ceramic siding materials. The existing loose bed 2 is provided as needed, and although it is present in most buildings, it is often not formed in -II houses. In addition, the existing exterior walls 3 are mainly made of concrete frames coated with cement mortar, concrete concrete exterior walls, ALC board-clad exterior walls, etc., and the exterior walls of buildings that were thought to be permanent have been cracked or partially destroyed. This targets exterior walls contaminated with moss, mold, etc. As shown in Fig. 2, the Kasagi mount 4 is attached with springback and screws, and varies depending on the shape of the jaw, knee, and knee Kasagi 5, and the cross section of the top of the existing rose vent 2.
For example, it is formed as shown in FIGS. 2 and 3, and is fixed to the flange 6 by adhesive bonding, welding, screws, or bolts 9a. The rim 6 is the fourth
As shown in Figure (a), the cross section is C-shaped channel-shaped, and the mounting legs 7 are mounted on opposite sides in a staggered manner to facilitate stability with a minimum number, and the bent portions of the body rim 6 are formed. 6a and the contact surface 78 of the mounting leg 7 having an L-shaped cross section, a gap of ΔG is formed as shown in FIG. so that you can get
Moreover, it is configured to reduce vibrations from the existing outer wall 3. As shown in FIGS. 1 and 6, the furring 6 is horizontally and vertically arranged in the form of a rod, and the necessary parts are integrated with adhesive or welding, and the existing outer wall 3 is attached to the existing outer wall 3 with anchor bolts 9. It is fixed integrally with the Of course, when the metal siding material 16 is vertically stretched, the furring 6 needs to be a horizontal furring. The attachment hole 8 is for attaching the attachment leg 7 to the anchor bolt 9, and is bored in a circular, oval, oval, etc. shape to accommodate displacement of the attachment position. As shown in FIG. 7, accessory 1) is a toe cover, accessory 12 is a board-shaped fixture for the toe edge cover 1), and accessory 13.13a is a window frame cover as shown in FIG. The accessory 14 is a protruding corner cover, accessory 1 as shown in FIG.
5 is a protruding corner cover attachment. Furthermore, the metal siding material 16 is a member having a shape as shown in FIGS. 10(a) to 10(1) and is attached as shown in FIG. 1, FIG. 1). In particular, the metal siding material 16 is easy to construct and has a synthetic resin foam 16c integrally interposed between a thin metal sheet molded body 16a and a backing material 16b, which have excellent heat insulation properties.

Next, the construction method will be explained.

First, scaffolding is assembled along the existing outer wall 3 of the existing building construction as shown in Figure 1. Next, the fuselage 6 as shown in FIG. 4(a) is formed to a predetermined length, and anchor bolts 9 are driven into the mounting legs 7 at positions corresponding to the mounting holes 8. The rim 6 is fixed to the anchor bolt 9 as shown in FIG.

A cap holder 4 shown in FIG. 3 is welded to the horizontal rim 6' constructed on the existing rosette 2 of this rim 6, and then a cap 5 is attached. In addition, at the counter there are accessories 13.13a shown in Figure 8.
Then, using a starter (not shown), install the metal siding material 16 shown in FIG. , near the Kasagi attachment 4 of the existing parabet 2 (
As shown in FIG. 7, a board-shaped fixture 12 is installed in advance. Next, after the construction of the metal siding material 16, the accessory 1). 14.15. The joints and the like are covered with a joiner (not shown), and then caulking material (not shown) is filled in the necessary places to complete the construction.

What has been described above is only one example of the repair structure of an existing concrete wall, etc. according to the present invention, and as shown in FIG. It can also be formed as shown in (1).

〔Effect of the invention〕

As described above, according to the structure for repairing an existing concrete wall or the like according to the present invention, (1) the outer wall can be repaired in a short period of time without stopping the occupancy of the existing building. ■By adding insulation to the exterior walls and dehumidifying properties through ventilation, livability can be improved and the lifespan of the building can be extended. ■New exterior walls are easy to construct, and beautiful and durable exterior walls can be formed at low cost. ■Metal siding materials do not require maintenance after construction, and maintenance costs are low.

■Since the mounting legs are arranged in a staggered manner on the body rim, the number of fixings to the existing exterior wall is minimal and stable, and the new exterior wall will not be destroyed or detached even by external forces (earthquakes, etc.). ■The body has a C-shaped channel cross section, making it lightweight and cost-effective. It has the following characteristics.
