Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention involves fixing a special rim vertically or horizontally on an existing exterior wall, and attaching a dry exterior wall material with a male and female connection structure to this rim using nails. Instead, it relates to an outer wall structure that can be used both horizontally and vertically, is elastically held by the body rim, and is repaired using a special slideable clip.

[Conventional technology]

To renovate the exterior walls of an existing building or house, there are two methods: ■ A structure in which the entire exterior wall is removed and a new wall is formed; ■ A structure in which the existing exterior wall is used as a base and dry exterior wall materials are directly fixed to it with nails; ■The structure was one in which a wooden rim, consisting of a C-shaped channel, was fixed to the existing exterior wall using nails and anchor bolts, and dry exterior wall materials were fixed to this using nails, screws, etc.

[Problem that the invention seeks to solve]

However, with the structure (■), the cost is enormous, the renovation period is long, and the residence must be stopped. There were drawbacks such as. In addition, the structure (2) not only cannot be applied to concrete or the like and has poor workability, but also has the disadvantages of waterproofing, dew condensation, corrosion of fixings due to impermeability, and lack of heat insulation.

Furthermore, since the structure (2) usually uses a C-shaped channel, it is costly and requires many construction sites. Moreover, the parts of the dry exterior wall materials that came in contact with the rim were fixed using tufting screws. As a result, there were disadvantages such as poor work efficiency and the need to drill large holes, especially in cases where aluminum expands significantly due to heat.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention forms the flange from an inverted gutter-like engagement part and an L-shaped mounting leg, which is elastically engaged and slid to attach to the dry exterior wall. The fixed part of the timber is supported with clips made of elastic material without detachment, and the support structure by driving nails etc. is easy to install, and the support structure is based on lips, which significantly shortens the construction period and reduces costs. It can be installed on an existing exterior wall in half the number of places required before, and requires no skill (it can be installed), and even if it is significantly deformed by heat, like metal siding made of aluminum, there will be no change in the decorative surface. This project proposes a renovated exterior wall structure that can be installed vertically or horizontally to avoid problems.

〔Example〕

An embodiment of the repaired outer wall structure according to the present invention will be described in detail below with reference to the drawings. FIG. 1(a) is a perspective view showing a case where the repaired wall according to the present invention is constructed on a concrete wall, and 1 is an existing external wall, which may be a concrete wall, or a mortar wall (not shown), a tile wall, an ALC wall, a block wall, etc. It consists of one type of wall, such as a wall made of ceramic-based exterior wall material or a curtain oar wall. The main part is the rim, which is attached to the existing external wall 1 at a predetermined pitch P vertically or horizontally with fixing devices 2 such as nails, anchor bolts, etc.
3, and is formed in a straight line from an engaging part 6 with a reverse gutter-like cross section and a mounting leg part 7 with an L-shaped cross section, with a clip engaging part to be described later at the top. It is.

The rule is to support dry exterior wall material 15 with a male and female connection structure on the trunk rim 1 with clips instead of nails, etc. 21 is a new exterior wall, 22 is a ventilation layer between the existing exterior wall 1 and the new exterior wall 21. It is a space that is formed, has an effective effect on the air cycle, and
3 is a fixing device consisting of nails, anchor bolts, etc. To explain further, as shown in FIGS. 2(a) and 2(bl), the rim 1 consists of a guide 3 that slidably engages the clip, a stopper 4, and a mounting surface 5 that abuts the back surface of the dry exterior wall material 15. The mounting leg part 7 is formed with a vertical rising part 8, a horizontal flange part 9 and, if necessary, a mounting hole 1o in a cross-sectional shape. If the thickness of the furrow I is 0.5 mm or more, mounting holes 10 are bored at an appropriate pitch.Furthermore, the furrow 1 is roll-formed. It is formed by injection molding, extrusion, etc., and its material is one of metal plates (Fe, AI!, stainless steel, Galfan, Galvalume steel plates), synthetic resin, and the plate thickness is 0.
It is 3rd to 5th dragon rank. In addition, as specific examples of the body rim 1, the length is about 600 to 7000 mm, the width W+ is about 10 to 80, W2 is about 1 to lOs, and Vh is about 1 to 10 m.

! So, H4 = 10~5D fin level, θ2 is zero or acute angle,
It has a shape that makes it easy to engage and disengage. In addition, as shown in FIG. 1(b) and FIG. 1(C), the clip holder has a shape that corresponds to the engaging portion 6 of the rim 1, and the clip holder is elastically attached to the rim 1 without detaching. It is formed from a locking part 13 having a locking pawl 12 shaped to sandwich the latching part 13, and a fixing part 15a of the dry exterior wall material 15, for example, an insertion pawl 14 that is inserted into and supported in an insertion groove. To explain further, the clip has a shape as shown in Figure 3 (a) and (bl), and requires the same support force as a nail or screw, so it is made of spring steel, stainless steel, or surface-treated steel plate. (0,5～
1 mm), structural steel plate, other well-known steel plate, aluminum, etc., and is formed by one or more processes such as roll forming, press working, extrusion, and integrating two parts with welding, rivets, and screws. This is what I did. To give a specific example of the dimensions, width W5≦W@, Wi≧W+ SW?

Note that Δh is determined by the shape and thickness of the fixed portion 15a. In addition, the dry type exterior wall material 15 is shown in FIGS. 4(a) to (hl
, and one of metal siding materials 16 and ceramic siding materials 17 as shown in FIGS. 5(a) to Fg+. In particular, the metal siding material 16 is formed by integrally forming a surface material 18, a core material 19 made of plastic foam, and a back material 20.

Next, the construction method will be explained.

First, it is assumed that a repaired exterior wall structure as shown in Figure 1(C) is to be formed, and a fourth
Assume that a metal siding material 16 as shown in Figure 2 (al) is to be constructed.Then, scaffolding is assembled around the existing outer wall 1, and then the siding 16 as shown in Figure 2 (aJ) is installed using the fixtures (
It is fixed to the existing outer wall 1 via anchor bolts) 23 at a predetermined pitch P=450 mm. Next, a starter material (not shown) is fixed to the base side of the first stage metal siding material 16, and the female connecting portion of the first stage metal siding material 16 is engaged with the starter material. This metal siding material 16
The fixing part 15a of the clip plate shown in FIG. While rotating and pressing in the direction of the arrow with force, the insertion claw 14 is inserted into the engagement groove 15b of the metal siding material 16 in the engagement groove 15b of the metal siding material 16 as shown in FIG. The fixing portion 15a of the metal siding material 16 is fixed to the rim I. Therefore, in order to form the new outer wall 2I, it is sufficient to repeat these steps sequentially from the base to the eaves. In addition, either install well-known accessories (not shown) around the foundation, exits, inside corners, and around windows, or install them last if they can be done after the metal siding material 16 is installed, and fill in caulking material where necessary. It is something. Additionally, starting materials are no longer required to form vertical exterior walls. The only thing to do is to provide the body trim horizontally and in parallel at some pitches.

[Other Examples]

What has been described above is only one embodiment of the repaired outer wall structure according to the present invention, and the main rim can also be formed as shown in Fig. 7 (al to (0)). ~(
0) is a modification of the engaging portion 6. Moreover, the clip part can also be formed as shown in FIG. This is explained by taking the circular gutter-shaped locking part I3 as an example. In other words, Fig. , fb1 shows a clip with a tongue piece 13a that serves as a pressing surface when sliding the clip, and +01 shows a clip with the locking part 13 and insertion claw 14 flush with each other (d1 shows an insert) Once the clip is formed by bending the tongue piece 14a that serves as a guide and reinforcing the end portion at the tip of the claw 14 in the opposite direction, the insertion claw 14 is shown in FIG.
When the clip is formed narrower than the locking part 13, (fl~(
hl is a case where the shape matches the waist plexus engaging portion 6.

〔Effect of the invention〕

As mentioned above, according to the repaired exterior wall structure according to the present invention,
Since dry exterior wall materials are fixed using sliding, resilient clips that are easy to install and remove without the use of nails, construction time can be significantly shortened and costs can be reduced. ■Since the clip elastically locks onto the body rim, it simply presses and engages, and does not come off. ■The rim is shaped like a straight bar, and the clip that holds it there is locked, so it can be installed regardless of whether it is stretched vertically or horizontally. ■A ventilation layer can be formed between the existing exterior wall and the new exterior wall, providing insulation and preventing condensation. ■The rim is fixed to the existing outer wall with a single mounting leg, and the overall cross section is almost L-shaped, making it easy to form, reducing costs, and increasing construction efficiency. It has the following characteristics.
