Abstract

PURPOSE:To facilitate execution by forming a steel foundation beam from a pair of flanges which set oppositely vertically and a web connecting the part between the flanges and fixing the frame assembly of a structure to an upper side flange. CONSTITUTION:A foundation beam 4 is formed with H-shaped steel consisting of a pair of flanges 5 and 6 which are opposed vertically and a web 7 connecting the center parts of a pair of flanges 5 and 6. A number of U-figure- shaped reinforcing steel 8 are previously welded, keeping intervals, between the flanges 5 and 6, and installed oppositely on both the sides, having the web 7 interposed. A trench is excavated on the ground, and after broken stones and gravel 2 are laid, an installation base 3 is installed. Then, after the concrete of the installation base 3 is solidified, the foundation beam 4 is installed on the installation base 3. Then, the stiffener plate 9 of one foundation beam 4 and the edge part of the other foundation beam 4 are joined by bolts 14 through a joint plate 13 through both bolt holes 10 and 11.

BACKGROUND OF THE INVENTION Conventionally, concrete has been generally used for the foundations of prefabricated houses. This type of concrete foundation is divided into two types: one in which the foundation concrete is cast on site, and the other in which a prefabricated precast concrete foundation is transported to the site and installed.

Problems to be Solved by the Invention In the above-mentioned conventional foundations, when concrete is poured in-situ, the steps are performed in the order of foundation reinforcement, assembly of formwork, pouring of concrete, and leveling of the top of the concrete. Each process requires skill, and it has the disadvantage of requiring a large number of skilled craftsmen of various types. In addition, the foundation concrete and the building frame are connected using anchor bolts buried in the concrete in advance, but in order to ensure the positional accuracy of the anchor bolts, the position of the anchor bolts must be corrected before installation to the frame. There are cases where so-called re-setting is required, which is inconvenient in that it requires complicated work and takes a long time.

Effects of the Invention As described above, according to the present invention, pre-formed steel foundation beams are transported to the site and joined, and therefore, compared to the case of construction using conventional cast-in-place concrete. This has the advantage that no special skill is required and the construction period can be significantly shortened. Further, since the anchor bolt holes or anchor bolts for attaching building frame members can be formed in advance at a factory, the accuracy is greatly improved, and there is no need to rebuild the structure after installation. In this case, as shown in the example, concrete is poured to cover the foundation beams, but since this concrete is only used to cover the foundation beams, complicated work such as leveling the top is required. There is no need for this method, and the work is much simpler than the conventional method. On the other hand, since the foundation beam uses an H-shaped steel material consisting of upper and lower flanges and a web, it is much lighter in weight than a concrete foundation using so-called flexible cast concrete, and is easy to handle on site. Since there is no need to shorten the length to reduce weight, and relatively long lengths can be manufactured in advance, there are fewer joints on site, which has the effect of reducing unevenness and irregularities in the road. It will be done. Furthermore, as mentioned above, by covering the foundation beams with poured concrete, it is possible to prevent the foundation beams from rusting, increase the weight of the entire foundation, and obtain a highly stable foundation. Effects can be obtained.
