The present invention relates to a height-adjustable ondol floor structure, and more particularly, by raising the floor plate by a predetermined height using a height-adjustable hardware, inducing weight reduction and minimizing the effect on the weight of the building. It's about structure.

The height of the adjacent floors is often different due to design or construction problems, and jaws are often formed. To achieve the same height, it is necessary to raise the lower floor. In addition, even if it is necessary to introduce an adjacent outdoor space into the room for remodeling an aging building or to expand the indoor space, it is required to raise the floor of the outdoor space to be equal to the floor height of the indoor space. In particular, in the case where the space where the floor is raised is converted into a living space, it is necessary to form an ondol floor structure by installing insulation and heating pipes. In this case, if a new floor layer having a thickness as high as the raised floor height is formed, the self-weight of the building may increase, resulting in structural problems in the building or an uneconomical problem due to an increase in the amount of materials required. The structural and economic aspects need to be reviewed sufficiently.

Accordingly, the present inventors have developed an ondol floor structure having a load capacity enough to absorb the load and impact loads of the upper part while reducing the weight of the ondol floor structure to increase the floor height.

The above embodiments are distinguished according to the material forming the thermal insulation bottom layer 60. That is, in the embodiments of FIGS. 1A, 1B and 2, the insulating bottom layer 60 is formed using lightweight foam concrete, and FIGS. 3A, 3B and 4 illustrate the insulating bottom layer 60 as a reinforcing material having a honeycomb structure. 610 and the filler 620 are formed.

The fixed angle 10 is divided into wing portions 11 at both ends and a central portion 12 protruded and bent into the center, and the wing portions 11 are fixed to the slab 1 and the coupling holes are formed in the center portion 12. It is formed, as in the embodiment wing portion 11 of the fixed angle can be fixed to the slab 1 using the Hiltifin 15 for concrete. Under the wing 11 of the fixed angle, a shock absorbing rubber pad 100 may be further installed, which is designed to cushion the impact load applied on the bottom of the slab 1 after the completion of the ondol floor structure of the present invention. This is to minimize the impact on the system.

The height adjustment bolt 20 is inserted into the coupling hole of the center portion 12 of the fixed angle to be fixed and coupled, and fastening means for fastening while adjusting the engagement position between the height adjustment bolt 20 and the fixed angle 10. Equipped. That is, how much the height adjustable floor structure of the present invention rises in the slab 1 is controlled by the degree of coupling between the height adjustment bolt 20 and the fixed angle (10).
