Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction method and hardware for fixing a wooden base wall to a concrete wall in a reinforced concrete building. Conventional methods for fixing a timber base wall to a concrete wall include nailing the timber base to wooden pieces that have been embedded in the concrete in advance, and nailing the timber base directly to the concrete surface. Therefore, there was a method of hammering. However, this construction method was expensive because the nails were easy to pull out, the labor required to finish the wall flat, and the labor involved in embedding the wood chips in the concrete and processing the wood chips.

This invention has been made to eliminate these drawbacks, and will be explained with reference to the drawings as follows.

Concrete l) -) r<f Separators (2) embedded in ft1 for fastening the formwork are approximately 60 cm apart vertically and horizontally. This separator (2) protrudes about 2 cm from the surface of the concrete wall (1). The protruding part is threaded.

This invention utilizes this protruding separator (2), screws an L-shaped metal fitting (3) with a nail hole with a nut into the separator (2), and then attaches the L-shaped metal fitting (4) with nails to the wooden base. It is fixed to the hardware (3). Next, to explain the construction example, the materials for the woodwork base (4) are approximately 3.
It is a square piece of wood from centimeters to four centimeters. However, since the surface of concrete wall (1) is uneven, concrete wall (1)
It is necessary to maintain the distance between the wall (1) and the wooden base (4).

Therefore, the length of the nail hole of the L-shaped hardware (3) needs to be about 4 cm, and the length of the L-shaped hardware (3) and the separator 12) must be adjusted accordingly. By adjusting the installation of the wooden base (4), a flat wooden base (4) wall can be constructed. Sunda Concrete 1/Wall (1) and woodwork base (
4) can be firmly connected and fixed using the 17-inch metal fittings (3). However, since the separator (2) is used to fasten the formwork, the separator (2) may not be present at the required location. If there is any other need, it is a good idea to embed separators (2) or hardware with the same threads in the concrete wall (11) in advance, but normally, separators (2) placed at 60 cm intervals vertically and horizontally are used for wooden construction. F ground (4) can be constructed.
