Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to houses, offices and other educational facilities (hereinafter referred to as houses, etc.). ], A wooden staircase (hereinafter, collectively referred to as a staircase) constructed as a straight staircase (including a staircase having a gently curved portion) excluding a spiral staircase or a folding staircase. In particular , the present invention relates to a staircase which is supplied as a precut product that can be assembled on site at the time of new construction and renovation construction, and has an improved structure so that fixed installation, temporary construction, or installation change can be easily performed. 2. Description of the Related Art Conventionally, when stairs are constructed inside a house or the like, as shown in FIG. 5, a side plate member (4) supports a plurality of treads (stepping) (8... 8). A stepped inclined passage (3) formed by arranging these in multiple stages is sandwiched. The means (method) for fixing the side plate member (4) to the upper floor and lower floor is generally a side plate member (method). Notches are provided at both ends in the longitudinal direction of 4), and they are mounted on an upstairs structural member (1) such as a spar and a downstairs structural member (2) such as a large-sized vehicle and simply nailed and fixed. . [0003] With this kind of fixing means (method), it is relatively stable because it is mounted on each structural material below the floor in the vertical direction against external force (load), but is fixed in the horizontal direction. In some cases, displacement (lateral displacement) occurred due to insufficient force (restraint). Here, it is necessary to fix and secure at least the upper structural member to the upper structural member. [0004] As described above, there is a concern that stairs by nailing may cause the following problems. [0005] When the building is subjected to deformation (external force) such that the building is at risk of collapse due to an earthquake or wind and flood damage, the building is likely to be laterally shifted,
No contribution to structural strength can be expected. In addition, there is a possibility that the stairs themselves may be disintegrated and the evacuation route may be disconnected, because the fixing to the structural members on the floor is released. Therefore, it must be said that it is defenseless especially in terms of earthquake resistance. [0006] Most of the conventional construction houses in Japan still use solid materials such as undried or naturally dried, and drying and shrinkage due to the drying progress several years after construction. However, loosening of the nails, rattling of the stairs and creaking are inevitable. [0007] The construction accuracy related to the installation of the stairs depends on the skill of so-called carpentry work, and an average improvement in accuracy cannot be expected. The present invention has been made in view of the above circumstances, and is supplied as a pre-cut product, can be easily constructed by assembling on site, can provide sufficient construction accuracy and installation strength, and can provide new construction and An object of the present invention is to provide a staircase whose structure has been improved so that it can be fixedly installed, temporarily installed, or its installation can be changed during renovation work. [0009] In order to solve the problems, the present invention relates to an upper structural member such as a girder, a lower structural member such as a large-scale pulley, or an intermediate structural member interposed and disposed below the upper floor. A staircase connected to a side plate member sandwiching a stepped inclined passage below the upper floor via a connection fitting, wherein a connection fitting having a flat plate element is provided on at least the upper structural member, and the side plate member is connected. The end is provided with a slit formed so as to divide the plate thickness into two, and the flat plate element of the connection fitting is inserted into the slit and detachably fixed. [0010] Here, stair passage forming member made of a fitting side plates member of stairs above configuration, the fitting plate member having a respective structural member and the flat plate element member end of the upstairs side in at least installed state has a possible separable joint structure attached via a connection metal fitting forms a flat plate angled, and those having a notched groove and the bolt holes in the one side of the flat plate element.

A slit (41) is formed at the connection end of the side plate member (4) sandwiching the stepped inclined passage (3) so as to cut the plate thickness in half.
The flat plate element (51) of the connection fitting (5) is inserted into the slit (41) and fixed detachably, so as to connect the stepped inclined passage (3) to the upper structural member (1). . Here, the side plate member (4), which is an element of the stair passage member, is connected to the upper structural member (1) at the end of the upper floor member and is separable from the upper structural member (1). In order to allow the flat plate element (51) of (5) to be inserted, a slit (41) is formed at the end of the member so as to divide the plate thickness into two parts, and the member (51) crosses the slit (41). It has a pin hole (42) and / or a bolt hole (43) penetrating on the front and back of 4). As shown in FIG. 3, the connection fitting (5), which is another element of the stairway passage component member, is formed by forming a flat plate into an angle shape, and is provided in one plane of the flat plate element (51).
