Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to construction auxiliary members used in the construction of houses, etc., and construction methods using the same. When placing a wooden base on the
The present invention relates to a construction auxiliary material that is effective in preventing corrosion of wooden parts when constructing a mortar exterior wall on wooden columns, and a construction method using the same.

[Conventional technology]

Traditionally, when installing a wooden base on a concrete foundation, a durable wood such as cypress or cypress was used and a preservative was applied on top of it, or a preservative was injected under pressure in advance. Wood was used.

Also, when constructing an exterior wall outside the wooden pillars, e.g.
When constructing a mortar exterior wall, each company creates a base of wood lath, then asphalt felt or waterproof paper is spread on top of it, held in place with wire lath, and mortar is applied.

[Problem that the invention seeks to solve]

These conventional construction methods for construction have the following drawbacks.

Due to moisture from the ground and rainwater blowing in from outside,
Wooden foundations and pillars corrode or flake in a relatively short period of time. This is because moisture tends to accumulate at the boundary between the foundation and the foundation, and the higher the degree of adhesion, the more easily moisture can penetrate through capillary action and become difficult to escape. Moreover, since there are no gaps, there is no air circulation and there is almost no chance of drying.

This humidity and water content makes it more susceptible to corrosion and damage from pests such as termites. These traces are often discovered during renovations and additions.

To counter this, we use durable cypress and Japanese cypress,
A preservative is coated on top of it, but the antiseptic effect of the preservative has a limit, and the more moisture and moisture it contains, the shorter the lifespan will be. In any case, it is much shorter than the lifespan of the building. Moreover, once a building is constructed on a foundation, it is almost impossible to apply preservatives to the entire foundation again, unless it is demolished and applied when remodeling or expanding. Even when preservatives are injected under pressure, the difference is the same.

Furthermore, durable wood such as cypress is difficult to obtain and is expensive.

The same thing can be said about architectural exterior walls. That is,
Between the wooden base or pillar and the mortar, asphalt felt or waterproof paper is placed on top of the wood siding as a base member to prevent water and moisture from penetrating the surface of the mortar outer wall and rotting the base or pillar. I try not to let it happen. However, since most of the wooden members are in close contact with the asphalt felt or waterproof paper, ventilation is poor and dew condensation is likely to occur. In this case as well, water gradually penetrates into the gaps due to capillary action, accelerating the corrosion of the wooden parts. Corrosion accelerates as the waterproofing effect deteriorates.

This invention eliminates the drawbacks of these conventional construction methods,
Moreover, it is an object of the present invention to provide a construction auxiliary member and a construction method using the same that can be provided at low cost.

[Embodiments of the invention]

Examples of the present invention will be described below.

FIG. 1 is an external perspective view showing the construction auxiliary member according to the present invention. (10) indicates the entire construction auxiliary member, which is an integrally molded product made of a weather-resistant and durable material such as epoxy resin. This longitudinal construction auxiliary member (10) is composed of the following parts. (1) is a flat connecting part D, (2a, 2b) is a predetermined interval (for example, 1 cm)
) are provided on the front surface (1a) and the back surface (1b) of the connecting portion (1), respectively, in order to communicate between one side end surface (1x) and the other side end surface (1y) of the connecting portion (1). There are multiple grooves. These grooves (2a, 2b) form the connecting part (1)
A plurality of protrusions (3a, 3b) are provided so that a plurality of protrusions are formed on each of the front surface (Ia) and back surface (lb). The dimensions of the protrusions (3a, 3b) are approximately the same as the grooves (2a, 2b) (for example, 1 cm)
A suitable ratio between the two is 1:1. Groove (2a, 2
b) is provided on one side end surface (I
The construction auxiliary member (
10) to have an air layer on both sides.

Furthermore, a plurality of protrusions (3a) protruding from the surface (1a)
The surface formed by connecting the tips of each, and the back surface (1b
) The respective tips (4a, 4b) are formed so that the surfaces formed by connecting the tips of each of the plurality of protrusions (3b) protruding from ) form two planes parallel to each other. , the thickness is constant. Therefore, the existing foundations and foundations can be used as they are.

Note that when the foundation (6) side is relatively dry, forming holes (5) in the grooves (2a, 2b) will improve the flow of air between the front surface (1a) and the back surface (lb). It gets even better. The width of the grooves (2a, 2b) and the tips (4a, 4)
The width ratio of b) is approximately 1:l in the figure, but
The ratio may be changed as appropriate. Furthermore, grooves (2a, 2
The cross-sectional shape of b) does not necessarily have to be rectangular, and may be semicircular, triangular, or the like. As shown in FIG. 2, the protrusions (3a, 3b) may also have a plurality of rectangular parallelepiped or cubic shapes in the width direction. While supporting both end faces (1
x, 1 y) may be connected to form a ventilation hole.

Next, a construction method for constructing a foundation and an outer wall using this construction auxiliary member (10) will be explained using FIGS. 3(a), (b) and FIG. 4.

Front side (1a) and back side (1b) of construction auxiliary member (10)
The tips (4a, 4b) form two planes parallel to each other in advance and have a constant thickness, so only the length and width dimensions are adjusted to match the dimensions of the wooden base (8). disconnect. At this time, it is easier to cut by using the boundary between the protrusion and the groove as a guide. Once cut, fix it using nails or the like so that the surface of the construction auxiliary member 10) is in contact with the back side of the base (8).

On the other hand, the anchor bolt (
Since the position of 7) varies considerably depending on the foundation work, a so-called core relief mark is placed on the top surface of the foundation (6) and the position of the anchor bolt (7) is measured using this as a reference line. After measuring the position of the anchor bolt (7),
Based on this measurement value D, the hole position for passing the anchor bolt (7) is determined based on the center line (so-called 8 ink) of the surface of the base (8) to which the construction auxiliary member (10) is attached, Holes are simultaneously drilled into the foundation (8) and the construction auxiliary member (10) from the surface side of the foundation (8). The work up to this point will be more efficient if it is done all at once in a factory or the like.

Next, the anchor bolt (7) is passed through the hole (5) provided in the foundation (8) and the construction auxiliary member (10), so that the back side of the construction support member (10) is in contact with the top surface of the foundation (6). and fix it. Anchor bolt (7) is Nando (9)
) etc. to tighten the screws. In this way, the base (
8) can be firmly fixed on the foundation (6).

After the foundation is completed, the exterior walls will be constructed. First, the pillar (11) is erected on the foundation (8). Next, grooves are placed so that the tip (4b) of the back surface (lb) of the construction auxiliary member (10) cut to a predetermined size is in close contact with the outside of the foundation (8) and the outside of the erected pillar (11). Attach from (2a) to the pillar (11) by driving nails, etc. After installing the construction auxiliary member (10), its surface (1a) may be coated with a base member (such as lath base, asphalt felt, waterproof paper, etc.) as necessary.
12), then apply wire lath (13), etc., and then apply mortar (14). In this way, between the foundation (6) and the foundation (8), between the foundation (8) and the base member (12), and between the column (11) and the base member (12), Attach the auxiliary member (10).

Incidentally, when constructing the outer wall, the lumber base may be eliminated and the construction auxiliary member (10) may play that role.

〔Effect of the invention〕

As explained above, according to the present invention, the plurality of grooves (2a, 2b) provided on the front and back surfaces of the construction auxiliary member are provided between the foundation and the base member or between the base member and the column. The holes act as ventilation holes, and air layers are formed on both the front and back sides, which allows for good air flow and prevents moisture build-up. This layer of air provides insulation and a barrier to moisture transfer, helping to prevent condensation from forming, and also prevents moisture from penetrating through the concrete or mortar, preventing moisture from penetrating through concrete or mortar. Therefore, corrosion and dandruff of the foundation and pillars can be prevented for a long period of time, and the material used does not need to be expensive wood such as cypress, but it can be put to practical use.

Furthermore, when using the construction auxiliary member, it is possible to freely cut long or short pieces using the boundaries between the protrusions and grooves formed at predetermined intervals as a guide. This construction auxiliary member can be used in common, whether it is used between a foundation and a foundation, or between an external wall such as mortar and a pillar or foundation, as long as it is cut to match the dimensions. In addition to being a molded product, it is suitable for mass production and is economical.

Furthermore, when constructing a foundation using the construction auxiliary member according to the present invention, the construction auxiliary member is attached to the foundation in advance, and when drilling a hole for penetrating the anchor bolt, the hole is drilled from the top side of the foundation, and the construction auxiliary member Since the holes are drilled at the same time, the subsequent steps are almost the same as the conventional construction method, which has the advantage of requiring less time and effort.
