Column frame structure for prefabricated house

Abstract

An object is to provide a column frame structure for a prefabricated house which enhances the efficiency of transportation, which maintains waterproof performance, and which achieve a satisfactory appearance in terms of appearance. A column frame 20 is foldably fitted onto a floor panel 40. A prefabricated house P in which a roof panel 10 is stacked on the column frame 20 is provided. When the prefabricated house is assembled, a gable end portion in the roof panel 10 is formed so as to be prevented from being protruded beyond the outside surface of the column frame 20. An eaves gutter 50 is installed so as to extend downward from the gable end portion in the roof panel 10. The eaves gutter 50 is formed so as to be prevented from being protruded outward beyond the outside surface of the column frame 20 on the gable.

DESCRIPTION OF EMBODIMENTS

(10) An embodiment of the present invention will be described below. The present invention is a prefabricated house P which is produced in a factory and is assembled locally (see FIG. 1).

(11) The prefabricated house P is transported in a state where a column frame 20 is folded so as to be stacked on a floor panel 40 and where a roof panel 10 is further stacked on the column frame 20 (see FIG. 2). Then, when the roof panel 10 is lifted locally (see FIG. 3), the column frame 20 is gradually developed, and when the prefabricated house P is assembled, the column frame 20 is arranged to stand between the roof panel 10 and the floor panel 40 (see FIG. 4).

(12) In the present invention, when the prefabricated house P is assembled, the outside surface 10A of a gable end portion in the roof panel 10 is prevented from protruding beyond the outside surface 20A of the column frame 20 on a gable which is arranged to stand (see FIG. 7). Furthermore, an eaves gutter 50 is installed so as to extend downward from the gable end portion of the roof panel 10, and the eaves gutter 50 is formed so as not to be protruded outward beyond the outside surface 20A of the column frame 20 on the gable 80 (see FIG. 1).

(13) On the upper end portion 20B of the column frame 20, a top plate 21 is provided. The top plate 21 is a portion which makes contact with the lower surface 10B of the gable end portion in the roof panel 10, and in particular, a concave portion 21A is formed in a part of the top plate 21 which makes contact with the eaves gutter 50. The concave portion 21A is formed such that the eaves gutter 50 fitted to the gable end portion of the roof panel 10 is overlaid on the concave portion 21A. Specifically, when the eaves gutter 50 is wound so as to be overlaid on the concave portion 21A of the top plate 21, the outside surface 50A of the eaves gutter 50 coincides with the outside surface 20A of the column frame 20 on the gable 80 (see FIG. 1).

(14) In the illustrated column frame 20, a gable beam 22 is provided which is arranged along the gable 80 of the roof panel 10, and the gable beam 22 swings together with the column frame 20 (see FIG. 6). When the prefabricated house P is assembled, the gable lower surface 11A of a roof beam 11 which supports the roof panel 10 is overlaid on the upper end portion of the gable beam 22 (see FIG. 9).

(15) The column frame 20 is swingably coupled through a coupling tool 60 to the roof beam 11 (see FIG. 5). The coupling tool 60 is formed with a coupling fixed member 61 and a swing fixed member 62. Specifically, the coupling fixed member 61 is a member which is fixed to the gable 80 of the roof beam 11, and includes a coupling pin 61A. On the other hand, the swing fixed member 62 is a member which is swingably coupled to the coupling fixed member 61, and is fixed to the side surface of the column frame 20 on the side of the upper end portion 20B (see FIG. 6).

(16) In the swing fixed member 62, an insertion hole 62A is formed through which the coupling pin 61A of the coupling fixed member 61 is inserted, in which the insertion hole 62A is formed in the shape of a long hole and thus the column frame 20 is moved in two steps, that is, a swinging movement and a slide movement (see FIGS. 6 and 7).

(17) Specifically, in order for the column frame 20 in a folded state to be arranged to stand, the column frame 20 is moved to swing about the coupling fixed member 61 of the coupling tool 60 (see FIG. 6). Then, the upper end portion 20B of the column frame 20 which is arranged to stand is moved to slide in a longitudinal direction (see FIGS. 7 and 8). In the illustrated example, the insertion hole 62A is formed in the shape of a long hole along the longitudinal direction of the column frame 20, and is provided such that the column frame 20 is moved to slide along the insertion hole 62A in the longitudinal direction (see FIG. 7).

(18) In an actual procedure, when the prefabricated house P is assembled, the roof panel 10 which is lifted is lowered, and thus the position of the column frame 20 is relatively moved to slide. When as described above, the column frame 20 is move to slide along the insertion hole 62A in the longitudinal direction, the gable lower surface of the roof panel 10 is overlaid on the top plate 21 of the column frame 20 (see FIG. 8). At the same time, the gable beam 22 is stored in the roof beam 11, and thus it is possible to enhance waterproof performance.

(19) When the column frame 20 is in the folded state, the position of the column frame 20 can be moved to slide horizontally along the insertion hole 62A, and thus it is possible to perform compact storage (see FIG. 5).

(20) The configuration of the prefabricated house P in the present invention is not limited to the illustrated example, and the configurations and the shapes of the roof panel 10, the column frame 20, the eaves gutter 50 and the like can be arbitrarily changed. The design can freely be changed without departing from the spirit of the present invention.
