Description

TECHNICAL FIELD The present invention relates to a stairway device capable of increasing the mounting strength and improving the appearance.

[Conventional technology]

For example, as shown in FIG. 3, an apartment house in which a stair S is provided in a recess C formed on an outer wall surface W of a house H is being adopted.

The stairs S in such an apartment house has a landing D projecting from the outer wall surface W, and the outer edge of the landing D is simply supported by the pillar B.

[Problems to be Solved by the Invention]

However, such a pillar B is sometimes inferior in rigidity, and when a resident such as a plurality of children or the like particularly jumps at the landing D, vibration due to the impact load and noise due to the vibration are generated, and the residence of the house is generated. In addition to impairing the property, such a pillar B tends to impair the appearance of the house.

The present invention is based on the fact that the outer edge of the landing is supported by a support panel having a steel rectangular frame, and the supporting strength of the stairs is increased to improve the yield strength of the stairs, and the appearance of the stairway device is also improved. It is intended to be provided.

[Means for Solving the Problems]

The present invention provides a staircase structure having a landing frame projecting outward from an outer wall surface of a house and extending inwardly toward the house at an inner edge of the house, and forming a staircase structure in the recess of the house recessed from the outer wall surface. A staircase device in which a pair of support panels, in which steel and rectangular frameworks are provided with face materials on the outer surface, are erected upright with an entrance left in the middle, and the support panels support both sides of the outer edge of the landing frame. Is.

[Action]

The outer edge of the landing frame of the staircase structure projecting outward from the outer wall of the house is supported by a support panel with steel and a rectangular frame on which the face material is arranged. Therefore, the holding strength of the landing frame can be increased, and a strong landing can be formed. In addition, the support panel has a surface shape and can be easily decorated such as by providing lighting to enhance the appearance of the house, and since the support panel is erected while leaving the doorway in the middle, the support panels are placed on the left and right of the doorway. As it is located, the appearance of the doorway makes it more profound and at the same time becomes a blindfold in the recess of the house.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, a staircase device 1 arranges a staircase structure 2 having a landing frame 3 for forming a landing D projecting from an outer wall surface W of a house H in a recess C of the house recessed from the outer wall surface W. At the same time, the outer edge of the landing frame 3 is supported by a support panel 5, and the staircase structure 2 faces the recess C of the house and surrounds the recess C. The recess wall Wc of the house. The inner part is held by the recessed frame body 7 which forms the.

As shown schematically in FIG. 1, the recessed skeleton structure 7 has a projecting corner post 10, 10 located at the intersection of the outer wall surface W and the recess C.
And the corner corner posts 11 and 11 located at the innermost corner of the recess C are erected on the cloth foundation 12, respectively, and between the exit corner pillar 10 and the entrance corner pillar 11 and between the entrance corner pillars 11 and 11. Lattice beams for upper floors 13,
It bridges 13 and 14. Also, above and below the lattice beams 13 and 14,
By arranging an appropriate wall panel (not shown), the recess wall Wc of the house facing the recess D is formed.

Further, the projecting corner post 10 and the entering corner post 11 are provided with appropriate beam members (not shown) that form floors, walls, etc. of the house H, and frame members including braces, so that the house frame structure of the house W (not shown). ) Is formed.

Further, a joint beam 15 straddling the lattice beams 13 and 13 is installed on the recessed frame body 7 in parallel with the lattice beam 14 and apart from the lattice beam 14. In addition, between the connecting beam 15 and the lattice beam 14, reinforcing beams 19, 19 connected on both sides by connecting beams 17, 17 are provided.
Are handed over.

The staircase structure 2 is composed of the landing frame 3 and upward and downward stairway portions 8 and 9 that are juxtaposed to the inner edge thereof and extend toward the interior of the house.

The landing frame 3 has a vertical member 23, inside the rectangular frame in which both ends of horizontal members 21 and 22 are joined by vertical members 23 and 23, in addition to a length that can be fitted into the recess C of the house. A reinforcing material 24 connecting 23 is bridged. The horizontal members 21 and 22 are made of grooved steel in which the groove portions are arranged outward, and the grooved steel in which the groove portions of the vertical member 23 are opposed to each other is used.

Further, the upward staircase portion 8 has an inclined portion 26 extending diagonally upward.
And a side girder 29 that has a horizontal portion 27 at its upper end and bends in a V shape,
A footboard or the like is bridged over the inclined portion 26 of 29, and a spindle connecting the horizontal portions 27 is fixed to a vertical connecting plate 30 of the lattice beam 13. Further, in the upward stair portion 8, the side girders 29, 29 are integrated into the inner edge of the landing frame 3, that is, in the horizontal member 22 by bolting or welding. Further, the inner end of the horizontal portion 27 of the side girder 29 is connected to the joint beam 15 of the recessed frame 7.

Further, the downward staircase portion 9 is composed of a linear staircase in which a footboard or the like is bridged between linear side girders 31 extending to the surface of the earth, and the upper end of the side girder 31 is attached to the inner cross member 22 and the upward staircase. It is fixed side by side with the part 8, and the lower end is fixed on a suitable pedestal 32.

Further, the side girders 29, 31 of the stairway portion facing downward and facing the projecting corner post 10, 10 are appropriately fixed to the projecting corner post 10, and thus the staircase structure 2 is recessed from the outer wall surface W of the house. It is arranged in the recess C.

The supporting panel 5 is an outer edge of the landing frame 3, that is, an outer cross member 21.
Support the lower surface. Also, in this example, the support panels 5 are arranged on both sides of the cross member 21 leaving an entrance in the middle.

The support panel 5 is, for example, a vertical member 34 made of channel steel,
A steel and rectangular peripheral frame that connects the upper and lower parts of 34 with upper member 35 and lower member 36 is provided with a frame 39 in which reinforcing lattices 37, 37 are bridged in a V shape, and on the outer surface thereof, A face material 40 is attached. Also, by applying an appropriate makeup to this face material 40, and by attaching an illuminator 41 and the like as shown in FIG. 2,
By improving the appearance of the house and having the steel frame 39, the landing frame 3 can be firmly supported.

The support panel 5 has the upper end of the frame 39 bolted to the lower surface of the cross member 22, and the lower end is erected on the surface of the earth via an appropriate foundation 42.

By providing a floor slab, a handrail, etc., the staircase structure 2 forms a folded staircase provided in a recess C of a house as schematically shown in FIG.

〔The invention's effect〕

In this way, the outer edge of the landing frame of the staircase structure protruding outward from the outer wall surface of the house is supported by the support panel having the surface material arranged on the outer surface of the rectangular frame made of steel, and thus the conventional support pillar is used. Compared to the one used, the holding strength of the landing frame can be increased, a strong landing can be formed, and the support panel can be made decorative such as providing a planar surface and lighting, and can enhance the appearance of the house. Since the support panels are erected while leaving the doorway in the middle, the support panels are located on the left and right of the doorway, increasing the appearance of the doorway and making it a blindfold in the house recess.
