Description

The present invention relates to overhang panel units and overhang panel structures.

Between the floors of the building, a plurality of brackets supported by girder and inter-story beams are extended to the outside through the vertical joints of the outer wall panels, etc., and are arranged at intervals. A panel unit (overhanging panel unit) that constitutes a balcony or eaves is arranged between the two arms, and is supported by bolting or the like to both arms. This overhang panel unit consists of, for example, two support beams (or joists) and a plurality of joists that are spaced apart in the longitudinal direction of the two support beams and connect the two support beams. , is equipped with

Here, a balcony has been proposed in which even if the width between the left and right sides of the balcony is large, the strength of the base portion of the balcony can be obtained simply by providing brackets only at the left and right ends of the balcony. Specifically, a floor frame composed of a front joist, a rear joist, and a plurality of joists is positioned between left and right brackets, one end of which is supported on the building side so as to protrude from the wall of the building. Then, the joists located at both ends in the length direction of the front and rear joists are fixed to the bracket with bolts and nuts. Further, an X-shaped horizontal brace is provided on the lower side of the floor frame, and turnbuckles are interposed at appropriate positions in the length direction of the two brace members crossing the X-shaped horizontal brace. The balcony is configured so that the length between both ends of each brace member is shortened by operating a turnbuckle between the front side pull and the vicinity of the rear end of each bracket (see, for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 2001-279807

By the way, when the width of the balcony is long, or when the width of the eaves is long like a continuous eaves, the structure in which the left and right ends of the overhang panel unit are fixed to two adjacent brackets with an interval is not suitable for the outer wall panel. Two or more are formed continuously in the width direction. For example, a long balcony or eaves can be exemplified in which four overhang panel units are arranged between five arms and each overhang panel unit is fixed to the corresponding left and right arms.

When attaching a plurality of overhanging panel units constituting a long balcony or eaves to a plurality of arms, it takes a lot of work to sequentially attach the overhanging panel units to each pair of arms. In addition, waterproofing is applied to the mounting points of the brackets and overhang panel units, but as the number of mounting points increases, the number of waterproofing points (or waterproofing joints) increases, resulting in an increase in the number of waterproofing points. Additional challenges may arise, such as increased risk of water leakage.

The present invention has been made in view of the above-mentioned problems, and when attaching an overhang panel unit that constitutes a balcony or eaves to three or more brackets, the overhang has good workability and can reduce the number of parts to be waterproofed. To provide a panel unit and an overhang panel structure in which the overhang panel unit is attached to three or more brackets.

In order to achieve the above object, one aspect of the overhang panel unit according to the present invention includes:
An overhanging panel unit that is integrally erected with respect to three or more brackets overhanging to the outside at intervals in the width direction of the outer wall from the structural framework between the floors of the building,
a plurality of support frames;
a connecting member that connects the support frames arranged with a gap;
a panel surface member fixed to the plurality of support frames;
The support frame includes two parallel support beams spaced apart from each other, and joists spaced apart in the longitudinal direction of the two support beams and connecting the two support beams. prepared,
It is characterized in that the arm is arranged in the gap.

According to this aspect, a plurality of support frames are connected by connecting members so that two or more support frames are continuous in the width direction of the outer wall, and the brackets are inserted into the gaps of the adjacent support frames to construct, Overhang panel units can be installed on three or more brackets at once. Therefore, the mountability (constructability) of the overhang panel unit to three or more arms is improved, and the number of waterproofing treatment points can be reduced, so that the possibility of water leakage from the waterproofing treatment points can be reduced.

The projecting panel unit of this aspect is a panel unit that constitutes a long balcony or a long eaves such as a continuous eaves on the outside of an outer wall between floors of a building. The support frame that forms the overhang panel unit includes two support beams made of shaped steel such as channel steel, angle steel, H-shaped steel, square steel pipes, etc., and also made of shaped steel, square steel pipes, etc. and a plurality of joists connecting two support beams. Adjacent panel units are connected to each other by connecting members formed of shaped steel materials such as channel steel or angle steel, or steel plates bent into channel shapes or the like. Furthermore, a panel face member is arranged and fixed above the adjacent support frames so as to straddle them. For example, there is a form in which one or two panel face members are arranged with respect to three support frames adjacent to each other. Adjacent support frames are connected to each other by connecting members, but the connection of adjacent support frames can also be contributed by arranging the panel surface members so as to straddle the adjacent support frames.

Another aspect of the overhang panel unit according to the present invention is characterized in that the connecting member connects the ends of the support beams of the adjacent support frames.

According to this aspect, by connecting the end portions of the support beams with the connection member, the plurality of support beams are integrated by the connection member to resist the bending moment generated by the dead weight or the surcharge load, and the bending resistance is increased. A superior overhang panel unit can be formed.

Another aspect of the overhang panel unit according to the present invention is characterized in that temporary hanging jigs are attached to at least two locations on the side surface of the support beam located on the outdoor side.

According to this aspect, the temporary lifting jigs are attached to at least two locations on the side surface of the support beam located on the outdoor side, and the lifting members (such as shackles) at the ends of the lifting wires are engaged with the temporary lifting jigs. For example, by installing the overhang panel unit while being suspended at two points, the overhang panel unit can be brought close to the outer wall while being suspended in a posture in which the support beam on the indoor side is inclined downward. Then, the overhanging panel units are dropped into the multiple brackets in order from the downwardly sloping indoor side support beam, and finally the outdoor side support beam that is directly suspended by the hanging wire is dropped, thereby damaging the exterior wall panel. The projecting panel unit can be smoothly installed on a plurality of brackets.

Also, by providing two temporary hanging jigs corresponding to, for example, two-point suspension, the number of temporary hanging jigs to be applied can be minimized. Furthermore, by suspending at two locations on the outdoor support beam, the temporary hanging jigs at the two locations on the outdoor support beam do not interfere with the installation. If temporary hanging jigs are installed at a total of four locations, the outdoor side support beam, the indoor side support beam, and both ends in the longitudinal direction of the overhang panel unit, and four-point suspension is performed, the indoor side support beam should be equipped with temporary hanging jigs. Temporary hanging jigs that are attached must be removed prior to installation because they interfere with the outer wall. Also, when installing an overhang panel unit in the inside corner of an outer wall, be sure to install a temporary hanging jig provided at either end of the overhang panel unit in the longitudinal direction, as it will interfere with the inside corner. must be removed prior to

Furthermore, for example, in the case of two-point suspension, the position where the deflection of the two-point-suspended overhang panel unit is the smallest is specified in advance, and a temporary suspension jig is attached to the two specified positions to perform the two-point suspension. It is desirable to As a result, breakage or the like of the panel surface material such as a waterproof steel plate can be suppressed or suppressed.

In addition, "At least two temporary lifting jigs are attached to the side surface of the support beam located on the outdoor side" means that temporary lifting jigs are attached to two or three or more points on the side surface of the support beam located on the outdoor side. It mainly means a form in which a jig is attached (a temporary lifting jig is not attached to the side of the support beam located inside the room), but the side of the support beam located inside the room is also used for temporary suspension. It does not exclude the form in which a jig is attached.

Further, in another aspect of the overhang panel unit according to the present invention, the panel surface member projects to the outdoor side from the support beam located on the outdoor side,

an overhang piece fixed to the joint piece and extending to the outdoor side and longer than the overhang of the panel surface material;
and a rising piece that is fixed to the overhanging piece and engages with the hanging member.

According to this aspect, when the panel surface material protrudes to the outdoor side from the support beam located on the outdoor side, the temporary lifting jig includes the joint piece bolted to the side surface of the support beam and the panel surface. The provision of the projecting piece longer than the projection of the material and the rising piece with which the hanging member is engaged eliminates the interference between the temporary hanging jig and the panel surface material, thereby providing a temporary hanging jig. The overhang panel unit can be hung with a hanging wire or the like through the In addition, the joint piece of the temporary hanging jig is bolted to the side surface of the support beam on the outdoor side, so that the temporary hanging jig can be easily joined to the support beam and can be easily removed from the support beam. It can be removed, and the workability of the overhang panel unit can be further improved.

In addition, one aspect of the overhang panel structure according to the present invention is
The gaps of the projecting panel unit are positioned with respect to three or more brackets projecting outward from the structural skeleton between the floors of the building at intervals in the width direction of the outer wall, and are dropped into the brackets. It is characterized in that the connecting member is engaged with the arm.

According to this aspect, the gap below each connecting member is dropped into the corresponding arm, and the connecting member is engaged with the arm, whereby the overhang panel unit is stably mounted on the plurality of arms. be able to. Here, the structural framework includes beams, columns, and the like that constitute a building, and examples thereof include girder spans and inter-floor beams.

A second bolt hole corresponding to the first bolt hole is opened in the lower surface of the support beam or the joist,
A part of the support frame is supported by the locking piece, and a bolt is inserted through the first bolt hole and the second bolt hole to bolt the arm and the overhang panel unit.

According to this aspect, a part of the support frame is supported by the locking piece projecting laterally below the arm, and the bolt is inserted through the first bolt hole of the locking piece and the second bolt hole of the support frame. By connecting the arms and the overhang panel unit with bolts, the overhang panel unit can be placed on the plurality of arms with greater stability.

Also, another aspect of the overhang panel structure according to the present invention is:
Under the arm, a locking piece projecting sideways and having a first bolt hole is attached,
A second bolt hole corresponding to the first bolt hole is opened in the lower surface of the support beam or the joist,
The gaps of the projecting panel unit are positioned with respect to three or more brackets projecting outward from the structural skeleton between the floors of the building at intervals in the width direction of the outer wall, and are dropped into the brackets. A part of the support frame is supported by the locking piece, and a bolt is inserted through the first bolt hole and the second bolt hole to bolt the arm and the overhang panel unit.

According to this aspect, the connection member is not locked to the arm and bolted in a state in which a part of the support frame is placed on the locking piece below the arm.
