Description

[Detailed Description of the Invention] The present invention relates to an improvement in the insulation structure of the floor portion of a small unit house constructed of steel frame assembly.

As is well known, in the case of a small unit house, four pillars made of steel frame materials, a framed ceiling frame, a floor frame, and left and right gable frames are used, and four pillars are welded and fixed to the four corners of the floor frame. A ceiling frame is installed at the top of the main pillar, and gable frames are installed on both left and right sides of the ceiling frame and floor frame to form the framework of the small unit house.In this case, the floor frame has an insulating structure. It is customary to have the following.

As for the heat insulation structure of such a floor, as is known, a heat insulating material of the same shape and size (polystyrene foam Alternatively, the floor panel material may be a two-layer structure consisting of a front panel board and a back panel board made of plywood, etc., and a heat insulating material may be placed in the space between the two panel materials. Either one is used.

In the former type, which combines a single panel material and insulation material, the thickness of the insulation material must be considerably thick in order to achieve the desired insulation effect, and in the latter case, the thickness of the insulation material must be considerably thick. In the case where the floor panel is filled with a heat insulating material, the structure of the floor panel is complicated and the manufacturing cost increases accordingly, which are disadvantageous.

Furthermore, during the assembly and construction of this small unit house, the steel columns and floor frames are usually welded, and spatter from the welding process can cause damage.
Another problem is that the heat insulating material may be burnt out.

The present invention eliminates the drawbacks and problems of these conventional methods, making it easier to install, effectively improving insulation, and eliminating burnout during welding. A heat insulating structure for the floor frame in a unit small house consisting of a ceiling, floor, and both gable frames made of steel frame materials, and pillars connecting the frames, the girder side being arranged around four circumferences of the floor frame. Floor panels are stretched across the upper surfaces of the girders and the small beams installed between the girders, and the lower surfaces of the buckling prevention beams installed perpendicularly to the lower surfaces of the girders are placed on the gable side girder side. At the same time, between this insulation material and the girder girder, a gable side insulation material is stretched in communication with the insulation material, and between the lower surface of the floor panel and both of the insulation materials. There is an independent air layer between them.

The invention will be described in detail with reference to the drawings below. Fig. 1 is a plan view of an embodiment of the invention, Fig. 2 is a partially cutaway slope view of the main structure, Fig. 3 is a longitudinal sectional front view of the same, and Fig. 4 is a plan view of an embodiment of the invention. Explanatory drawings of examples of unit small house frame assembly are shown, but in Fig. 4,
A is a ceiling frame made of steel frame materials, B is a floor frame, and C9C is a gable frame, and each of these frames A, B, C, and C has a gable frame C9C erected at the four corners of the floor frame B. By attaching the ceiling frame A to its upper end, a small unit house frame is completed.

A small unit house is constructed by attaching necessary exterior materials and other materials to this structure.

In such a small unit house, the present invention is a heat insulating structure in the floor frame B, and as shown in Fig. 1.2.3, the floor frame B has a pair of corresponding beams 2 and 2. , girder side girders 3, 3 connected between the pillars at both ends of both girders 2, 2, and small beams installed at regular intervals between girder side girder girders 2, 2 in parallel with these girders 3, 3. 4, and pillars 10 (same as the pillars shown in Figure 4) are erected in a fixed manner by welding or other means, as will be described later, at the four corner positions where the large beams 2 and 3 meet. be done.

In this invention, each girder 2 in such a floor frame B,
A floor panel 1 is stretched over the entire upper surfaces of the beams 3 and 4.

At this time, the small beams 4 are made of C-shaped steel materials as shown in the figure, and are arranged in parallel so that their C-shaped opening faces face each other, and both ends of the small beams 4 are welded to the inner surfaces of the girder girders 2, 2. For the purpose of preventing buckling of the small beams 4, a buckling prevention beam material 5 (made of wood or other ), and a heat insulating material (made of polystyrene foam or the like) 7 is stretched using a fastener such as a peg, using the lower surface of the buckling prevention beam 5 as a mounting surface.

At this time, the size of the insulation material 7 is
, 2-ken has a length spanning the entire length, but the girder side girder 3
, 3, as is clear from Figures 2 and 3, the buckling prevention beams 5, 5 are stopped at a length that does not reach the girders 3, 3, and are stopped at a distance from the girders 3, 3. The length is such that both ends of the heat insulating material 7 slightly protrude from both ends, thereby leaving a gap between both ends of the heat insulating material 7 and the inner surfaces of the girders 3, 3.

The heat insulating material 7 installed over the lower surface of the beam 5 in this way
Between the two ends of the girder and the girder girders 3, 3, gable side connecting insulation materials (same as the insulation material 7) 8, 8 are connected and constructed in a closed manner.

That is, one end of this insulating material 8 is fixed to the gable base material (made of wood or the like) 6 attached to the inner surface of the gable beam 3, and the other end is fixed to one end of the insulating material 7 stretched on the lower surface of the girder 5. As shown in the third figure, by polymerizing and bonding and integrating with the adhesive 11, the insulation materials 7, 8.8 completely cover the lower surface of the floor frame B corresponding to the floor panel 1, and thus An independent air layer 9 is defined between the floor panel 1 and the heat insulating materials 7, 8, 8, which shuts off the inside and outside.

When assembling the floor frame B, the buckling prevention beam material 5 is attached to the lower surface of the small beam 4, and the work of extending the heat insulating material 7 to the lower surface of the beam material 5 is performed by inverting the floor frame B. This is done in advance by facing downward, and the installation of the gable side connecting insulation materials 8, 8 will be done after the unit frame assembly and welding work.

According to the floor insulation structure of the present invention, in the floor frame B,
Between the floor panel 1 on the top surface and the insulation materials 7, 8.8 on the bottom surface, there is an independent air layer 9 that is completely blocked, so the air layer 9 has a heat insulating effect and the heat insulation material 7,8
．． This means that the heat insulating effect can be further increased compared to the case where only 8 is used.

In other words, if the insulation effect is the same as that without this air layer 9 and where the insulation material is laid directly on the back side of the floor panel 1,
The thickness of the heat insulating materials 7, 8.8 in this invention is the thickness of the floor panel 1.
5 mm from the case where insulation material is laid directly on the back side of
Furthermore, in the present invention, in order to obtain a synergistic effect between the air layer 9 and the heat insulating material 7°8.8, the structure of the floor frame B is utilized, and the small beam 4 is
It is only necessary to extend the heat insulating materials 7, 8.8 through the buckling prevention beams 5 on the side, which is more effective than the conventional floor panel having a double panel structure and filling the middle with heat insulating material. It is clear that a simple structure is sufficient and that it can be obtained economically at low cost.

Furthermore, when installing the insulation material away from the floor panel 1, on the side of the girder beams 3 and 3 where the welding work of the pillars 10 will be performed, the girder beams 3 and 3 should be installed so as not to burn out the insulation material due to welding spatter. , 3, a heat insulating material 7 is stretched apart from the
By connecting the gable side insulation materials 8 and 8 after welding, it is possible to cover the entire lower surface and create an independent air layer 9 between it and the floor panel 1, ensuring the insulation effect of the air layer 9. There is no heat generation or burnout of the heat insulating material, which is particularly advantageous as a floor heat insulating structure in small unit houses.
