Description

  The present invention relates to a fence structure or a handrail structure installed on a passage, a roof, a staircase, a balcony, or the like that partitions partition boundaries or site boundaries, or is installed as a fall prevention facility in a structure such as an apartment or building.

  Conventionally, various fence structures have been proposed as, for example, a fence that partitions a partition boundary or a site boundary, or a fall prevention fence in a structure such as a condominium or a building.

  For example, Patent Document 1 below proposes a fence structure including a pillar material standing from the ground and a fence unit supported by the pillar material. The fence unit is configured to include a frame body in which four upper and lower horizontal frame members and left and right vertical frame members are framed, and a punching metal as a face material on one side surface of the frame body. Are installed at predetermined intervals, and the fence units are sequentially fixed to one side of the column member.

Further, in Patent Document 2 below, the divided strut materials that become one strut by being engaged with each other by the engaging portion are arranged at a predetermined interval in a direction in which the engaging portion is engaged with the mating engaging portion. The horizontal members are placed between the upper and lower parts of both divided struts, and a stand or panel is attached in the space enclosed thereby to constitute one unit. Assembling and connecting so that one strut is formed with split strut materials to be combined, a cap structure is put on the assembled strut, or a fence structure in which the strut is built on the construction surface while tightening from around with a band is proposed Has been.

  However, in the case of the fence structure according to Patent Document 1, since the fence unit is sequentially fixed to one side of the pillar material, the appearance and design are poor, and the width (thickness) dimension of the fence is large. turn into. In addition, there is a problem that much work and time are required for fixing the fence unit to the pillar material.

  On the other hand, in the case of the fence structure described in Patent Document 2, the strut material is configured by combining the divided strut materials provided on both sides of the unit, and is excellent in appearance and design properties. This has the advantage that the width (thickness) can be reduced. However, in construction, if you assemble multiple units in the longitudinal direction while lying on the ground or floor, etc., to prevent the split strut material from splitting, after covering with a cap or tightening with a band, Since it is necessary to build in the construction surface, there are problems such as a lot of labor and time for the assembling work and the construction work requiring a plurality of workers.

  In addition, because the structure is such that the divided strut members are joined together in the horizontal direction, if one unit is damaged and must be replaced, it is practical to replace only one unit. There are also problems such as being difficult or large construction.

  Therefore, a main problem of the present invention is to provide a fence or a handrail structure that is easy to assemble and construct (build), is excellent in appearance and design, and can be easily replaced in units. .

In order to solve the above-mentioned problem, as the present invention according to claim 1, the pillar core material erected in advance at a predetermined interval on the construction surface, the divided strut material arranged on both sides, and the upper and lower parts. A fence or handrail structure consisting of a unit material in which four sides are framed by a cross member and a panel or a plurality of crosspieces are arranged inside the frame,
The unit material split strut member has a half frame portion that encloses substantially one half of the pillar core member in a cross-sectional view, and an engagement portion for the pillar core member at each end of the half frame portion. The column core material has an engaged portion at a portion corresponding to the engagement portion, and the half-frame portion of the unit material is dropped into the column core material from above, whereby the divided strut material Is attached to the core material for the column, and the unit material is attached. The column is constituted by a combination of a pair of divided support materials surrounding the core material for the column. A fence or handrail structure is provided which is characterized by not being engaged.

  In the first aspect of the present invention, the four circumferences are framed by the pillar core members that are erected on the construction surface at predetermined intervals in advance, the divided strut members disposed on both sides, and the cross members disposed on the upper and lower portions. In addition, a unit material in which a panel or a plurality of crosspieces are arranged inside the frame, the divided support material of the unit material has a half frame part that surrounds a substantially half on one side of the pillar core material in a sectional view, Each half frame portion has an engaging portion with respect to the pillar core member, and the pillar core member has an engaged portion at a portion corresponding to the engaging portion in the installed state. . In construction, the half-frame portion of the unit material is dropped into the pillar core material from above, so that the divided pillar material is engaged with the pillar core material and the unit material is attached. In the installation completion state, the strut is configured by a combination of a pair of split strut members surrounding the pillar core member, and the split strut members are not directly engaged with each other.

  Therefore, the divided strut members provided on both sides of the unit are combined with each other to form the strut material, and it has advantages such as excellent appearance and design and reducing the width (thickness) dimension of the fence. In addition, since the column core is erected on the construction surface at a predetermined interval in advance and the unit material is installed by dropping it as a support material, the assembly and construction become very easy. The split strut members are not directly engaged with each other, and a single strut member is formed via a pillar core member. Therefore, if one unit is damaged, it must be replaced. Even in such a case, only the damaged unit can be lifted upward and removed easily, and a new unit material can be easily installed by dropping. Furthermore, since the divided strut members of the unit are combined so as to surround the core material for pillars to constitute a single strut material, it can be easily replaced even when the strut material is damaged.

  On the other hand, this fence or handrail structure incorporates a panel or a plurality of crosspieces (vertical crosspieces, horizontal crosspieces, louvers, etc.) inside the frame of the unit material so that various types can be adopted. A panel format, a vertical grid format, a horizontal grid format, a louver format, and the like can be arbitrarily selected, and a combination of these formats is also possible. In addition, it is possible to easily cope with format changes after aging.

  According to a second aspect of the present invention, there is provided a fence or a handrail structure according to the first aspect, wherein a longitudinal through-head member is disposed on the upper surface of the upper side cross member.

  According to the second aspect of the present invention, in order to improve the appearance and design, or as a handrail material, a longitudinal through-head member is disposed on the upper surface of the upper side cross member.

  A fence or a handrail structure according to any one of claims 1 and 2, wherein a solid sealing material is interposed between vertical joints of a pair of divided support columns surrounding the pillar core material as the present invention according to claim 3. Is provided.

  The invention described in claim 3 is configured such that a solid sealing material is inserted between a pair of divided strut members surrounding a column core material in order to seal a gap in a vertical joint between the divided strut members. is there.
