Description

  The present invention relates to a large-sized outer wall panel used as an outer wall material for a steel-based building or the like such as a logistics facility.

  Some of the outer walls of buildings such as logistics facilities and convenience stores are constructed by arranging a plurality of outer wall panels with a metal sandwich structure in which non-combustible heat insulating materials such as rock wool are sandwiched between steel plates. In order to construct such an outer wall, conventionally, as shown in FIG. 19, a base frame 43 is attached in advance to a building frame made of slabs, columns, beams, etc., and the plurality of sheets are attached to the main frame 43. The outer wall panel 42 is attached. In order to sew the outer wall panel 42 to the trunk edge 43 attached in advance, a scaffold that can be directly operated from the outside is installed on the panel mounting surface of the building frame.

Japanese Patent No. 3029789 Japanese Patent No. 4007757 Japanese Patent No. 2916675 Japanese Patent Laid-Open No. 06-316984 JP-A-11-256736

  In the conventional outer wall structure described above, it is necessary to install a scaffold (not shown) for mounting the outer wall panel 42. For this reason, there has been a problem in that construction that affects the scaffolding for panel mounting construction, for example, exterior construction, etc. stays. Moreover, since the outer wall panels 42 are lifted one by one and attached to the body edge 43 of the building frame, there is a problem that it takes time and this also increases the construction period.

  An object of the present invention is to provide a large-sized outer wall panel that does not require installation of a scaffold for installation work of an outer wall panel on a building frame, and that can save labor and shorten the construction period.

  The large-sized outer wall panel according to the present invention includes an outer peripheral frame portion in which left and right vertical frame members and upper and lower end horizontal frame members are assembled in a rectangular shape, and upper and lower ends arranged on the outer peripheral frame portion at intervals in the width direction. Includes a panel frame composed of a plurality of vertical body edges joined to the upper and lower horizontal frame members, and a plurality of horizontally long outer wall materials including a heat insulating material attached to the panel frame.

  According to this configuration, since it is composed of a panel frame composed of an outer peripheral frame portion and a plurality of vertical body edges and a plurality of horizontally long outer wall materials attached to the panel frame, the plurality of outer wall surfaces are formed. Materials can be collected and attached to the building frame. Therefore, it is possible to save labor and shorten the construction period compared to a conventional outer wall panel mounting structure in which individual outer wall panels are mounted one by one on the building frame. Since the work of attaching the panel frame of the large-sized outer wall panel to the building frame can be performed from the floor slab in the building frame or on the steel beam, the scaffold that was conventionally necessary on the outer periphery of the building frame is also from this point. It becomes unnecessary.

  In this invention, the outer wall surface material may be a metal sandwich panel in which a heat insulating material is sandwiched between front and back metal plates. When it is a metal sandwich panel, it is lightweight and has excellent heat insulation properties. When it is made large, the weight does not become too heavy and the workability is excellent.

  In the present invention, the joint between the vertical frame member, the horizontal frame member, and the vertical trunk edge may be a pin joint. “Pin joint” as used in this specification refers to a joint structure that can be regarded as a pin joint when the nodes between members are classified into a rigid joint and a pin joint in terms of structural mechanics. , Welding may be used. With pin bonding, even when an interlayer displacement occurs in the housing due to an earthquake or the like, the deformation can be absorbed by the panel frame, and excessive stress and deformation can be avoided in the large-sized outer wall panel.

  In the present invention, a frame mounting fastener for mounting the large-sized outer wall panel to a building frame may be provided on the horizontal frame member at the upper end. In the case of this configuration, the large-sized outer wall panel can be attached to the building frame without welding, and attachment work becomes easier.

In the present invention, the upper-side inter-panel upper joint portion that joins the upper-side and lower-side wide frame panels arranged on the upper and lower sides of the large-sized outer wall panel to each other in an allowable state. In addition, a lower joint between the panels may be provided.
When the upper and lower large-sized outer wall panels are installed in a state in which mutual vertical movement is permitted, interlayer displacement occurs in the housing, and even if the height of the panel frame fluctuates due to deformation, it can be absorbed. An unreasonable load is prevented from acting on the panel frame.

  As described above, when the large-sized outer wall panels are configured to join each other in an allowable state of mutual vertical movement, the lower joint portion between the panels is a dowel pin protruding from the upper surface of the upper side horizontal frame member, The inter-panel upper joint portion may be a pin fitting hole into which the dowel pin of the large-sized outer wall panel arranged on the lower side is fitted. If the dowel pin is used, the vertical displacement can be absorbed with a simple configuration.

  The large-sized outer wall panel according to the present invention includes an outer peripheral frame portion in which left and right vertical frame members and upper and lower end horizontal frame members are assembled in a rectangular shape, and upper and lower ends arranged on the outer peripheral frame portion at intervals in the width direction. Is provided with a panel frame composed of a plurality of vertical trunk edges joined to the upper and lower horizontal frame members, and a plurality of horizontally long outer wall materials including a heat insulating material attached to the panel frame. In addition, it is not necessary to install a scaffold for mounting the outer wall panel on the building frame, which makes it possible to save labor and shorten the construction period.
