Description

TECHNICAL FIELD The present invention relates to a stone curtain wall unit used for a building exterior.

[Prior Art] When a stone panel such as granite is used for the exterior of a building, the construction period is shortened and the construction is shortened in place of the conventional curtain wall construction method in which it is individually stretched at the building site. For ease of use, a method has been proposed in which a curtain wall unit that has been unitized in a factory is configured in advance and is installed on a building.

In this case, a plurality of stone exterior panels are stretched on the front side of a steel frame having appropriate dimensions, as in the case of using panels made of other materials.

[Problems to be Solved by the Invention] However, an actual example of this type of stone unit, Shokai 63
The device disclosed in Japanese Patent No. 62520 has the following problems.

Since the weight of stone and cement mortar attached to the curtain wall unit is supported only by the reinforcing base frame, careful handling is required so that the unit is not deformed during transportation or suspension.

The amount of water impregnated into the stone itself with rainwater and leaching to the back through the interior of the stone, and the amount of direct infiltration from between the stone and stone, respectively infiltrate the body and leak water, resulting in an indoor board This may cause stains and rust on metal parts such as fasteners for fixing the stone curtain wall unit.

Further, since the cement mortar is filled and solidified on the back surface side of the stone material, the time required for manufacturing is extra due to the hardening time.

Further, since the cement mortar adheres the reinforcing base frame to the stone material, it is almost impossible to replace the stone material.

Further, since the coefficient of thermal expansion of cement mortar is smaller than the coefficient of thermal expansion of the reinforcing base frame, stress is generated between the reinforcing base frame and the cement mortar, and the bond becomes weaker with time.

The present invention has been made in view of the problems in such a conventional stone curtain wall unit, and in addition to the advantages of unitization, for example, labor saving on site construction or the need for scaffolding, etc., An object of the present invention is to provide a stone curtain wall unit capable of adopting a dry method in order to surely prevent site troubles such as dirt and deformation of a stone panel.

[Means for Solving the Problems] In accordance with the above-mentioned object, the present invention includes a high-breaking-strength insulating panel located inside and outside itself and a stone exterior panel. The panel shall have air-tightness and water-tightness and surface strength, and the stone exterior panel made of stone shall be attached to and retained by this barrier high-strength panel in a superposed manner with a gap between them. While solving the problems found in the stone curtain wall of No. 1, while at the same time realizing the above-mentioned object by preventing expected troubles, the present invention is a reinforcement made of square steel. A steel high barrier is integrally stretched over the entire surface of the base frame to retain airtightness and watertightness and surface strength, and a barrier high-strength panel that is attached and fixed to a building frame via a fastener, and the barrier high-strength panel. Fixed to the position of the reinforcing base frame, and the tip Reinforcing holders each having a pair of upper and lower portions with locking portions, and receiving and locking the leading end locking portions of the reinforcing holders in the engraving structure of the upper and lower edges, and separating from each other on the front side of the breaking high-strength panel. A stone curtain characterized in that a plurality of stone exterior panels are provided so as to be superposed in a superposed manner through a gap, and a sealing means is applied to a side facing a stone curtain wall unit adjacent to a reinforcing base frame. Relating to the wall unit (claim 1),
And each of these is the gist.

[Operation] In the present invention, since the steel shielding wall has surface strength, it is difficult to deform during transportation and installation of the curtain wall.

Due to the watertightness of the steel barrier, it is difficult for the stone itself or rainwater that has entered between stones to enter the body.

Since cement, mortar, etc. are not used to fix the stone material to the reinforcing base frame, the manufacturing time of the curtain wall unit is shortened by the hardening time.

Further, since the stone material is fixed to the reinforcement base frame by the reinforcement holder, the stone material can be replaced.

Further, since the stone material is attached to the high-strength panel by the flexible structure by the reinforcing holder, it is flexible against the displacement of the relative position due to the difference in thermal expansion, and can withstand long-term use.

Further, since the back surface of the steel shielding wall is smooth, a fireproof material or the like can be easily attached.

[Examples] The present invention will be further described below with reference to the drawings illustrating examples.

By the way, the stone exterior panels 16 supported by the reinforcing holders 9, 10 and 11 and additionally attached to and held on the front side of the barrier high-strength panel 2 are attached to the barrier high-strength panel 2, respectively.
While a spaced gap 19 of 30 mm is provided and overlapped with this, a lateral groove space 20 is provided between each stone exterior panel 16 ...

That is, the separation gap 19 is formed by the reinforcement holders 9, 10,
The tip locking portions 13 of 11 are secured by being installed separately from the mounting base 12, respectively, and the groove space 20 is
Each tip locking portion 13 is secured by being provided in the vertical direction.

The groove space 20 is opened as it is except that it is partially closed by the packing 21 attached to the reinforcing holders 9, 10 and 11 at the longitudinal ends thereof. With the groove space 35 between the curtain wall units 1 which will be described later, the separation space 19 is communicated with the outside, and the separation space 19 is a space of equal pressure to the outside.

Each curtain wall unit 1 configured in this way
Are attached and fixed to the building frame at each of four locations via fasteners 26 as shown in FIGS. 3 and 4.

That is, the fastener 26 includes upper and lower L-shaped metal fittings 27 and 28 welded to the blocking inner panel 2, a base metal fitting 29 fixed to a building frame 39 by an embedded bolt 30, and a building side L welded to the base metal fitting 29. The L-shaped metal fitting 31 is provided, and the lower L-shaped metal fitting 28 of the blocking high-strength panel 2 is fastened with a bolt nut 32 so as to be vertically and horizontally adjustable with respect to the L-shaped metal fitting 31 on the building side.

The attachment and fixation are made. Reference numeral 33 in the figure denotes a bolt nut for positioning and temporarily fixing the L-shaped building side 31 before welding.

By the way, as shown in FIGS. 4 and 5, in the space between the curtain wall units 1 and 1, the space between the edges of the stone exterior panels 16 ... The caulking material 36 is filled in the space on the left and right, and the caulking material 36 is closed over the entire length in the vertical direction where rainwater is relatively easy to enter, and the curtain wall units 1, 1 The packings 38, 38 attached to the space member 37 between them make it continuous, while the upper and lower spaces are in the form of an open seal that can be left as it is as a groove space 35 as shown in FIG. Similar to the groove space 20 between the stone exterior panels 16 of the one curtain wall unit 1, the separated space 19 serves as a ventilation path for making a constant pressure space.

Since the separated space 19 and the groove spaces 20 and 35 are provided in this manner, each curtain wall unit 1,
Hollow packings 38, 38 pressed against each other are interposed between the high-strength insulating panel 2 and the high-strength insulating panel 2 to shut off the high-strength insulating panel 2 and the concrete on the building frame side. , Airtightness Watertightness is secured.

In the longitudinal direction of the reinforcing base frame 3, the packings 38, 38 are fixed to the vertical frames 6, 6 and are continuously mounted in the longitudinal direction of the spacing members 37, 37 interposed therebetween. Thus, the upper and lower curtain wall units 1 and 1 are penetrated through, and in the lateral direction, the upper and lower frames 4 and 5 are directly attached and fixed to the entire length in the longitudinal direction.

On the other hand, 22 in the figure is the upper curtain wall unit 1

At this time, a nut 24 welded to receive the bolt 22 is provided on the lower surface of the lower frame 5 so as to face the receiving metal fitting 23, and these are mutually attached when the curtain wall unit 1 is fixedly attached. Although it is said that they may come into contact with each other, when the nut 24 and the receiving metal fitting 23 come into contact with each other, the groove space 35 between the upper and lower units 1 and 1 still remains so that the stone exterior panels 16 ... The positional and dimensional relationship is regulated so as to prevent collision.

In addition, reference numeral 25 in the figure denotes a heat insulating material filled in each blocking high-strength panel 2 for preventing dew condensation on the steel shielding wall 8, and the stone exterior panel 16 ... It is provided with a certain degree of certainty so as not to cause water absorption stains.

FIG. 6 shows another embodiment as a representative at the position of the middle frame 7, and in this example, the reinforcing holder 40,
41 is made of aluminum alloy mold material having a thickness of about 7 to 8 mm, and 38 mm stone exterior panel 16 is used.

The reinforcing holders 40 and 41 are both long in the lateral direction, while the engraved groove 45 provided on the edge of the stone exterior panel 16 ... It is assumed that the tip locking portion 42 of the reinforcement holder 40, 41 is
By receiving and engaging the outer panel 16 ...
Are respectively supported in the lateral direction.

At this time, the reinforcing holders 40 and 41 are separated and the inner frame 7
The lower reinforcing holder 40 is fitted to the U-shaped bearing groove 44, while the upper reinforcing holder 41 is mounted on the upper supporting holder 41. Is adapted to be screwed onto the mounting substrate 43 by screws.

The reinforcing holders 40 and 41 are separated from the mounting board 43 because the reinforcing holders 40 and 41 are removed from the mounting board 43 even after the curtain wall unit 1 is mounted and any stone exterior panel 16 is replaced. This can be done individually as needed.

Further, in this example, the reinforcing holders 40, 41 and the elongated packing 21 are provided with intermittent notched portions 46, and the separated voids 19 and the outside are inserted therethrough to form an isobaric space. There is.

Since the remainder is basically the same as the above example, the same reference numerals are given and the description is omitted.

On the other hand, FIG. 7 shows an embodiment, and in this example, the reinforcing holder at the upper end of the stone curtain wall unit 1 is directly below the lower frame 47 of the sash frame, and the reinforcing holder at the lower end is directly below. It replaces the upper frame of the sash frame 48 of.

That is, the sash lower frame, which is a window sash frame, is provided at the position of the reinforcing base frame 3 on the window side of the blocking high-strength panel 2 configured as described above.
The sash lower frame 47 and the sash upper frame 48 are integrally fixed to the sash lower frame 47 and the sash upper frame 48, respectively, in a vertical direction in the opposite direction by a screw while the sash lower frame 47 and the sash upper frame 48 are attached and fixed by screws via the electro-tack preventing material 50. Portions 49 are provided in a protruding manner, and the stone exterior panel 16 ... Is provided with engraved grooves 45 over its entire length at the opposite edges thereof in the same manner as in FIG. Each of the sash lower frame 47 or the upper frame 48 is configured to receive and lock the protrusion locking portion 49 and to support each of the stone exterior panels 16 ...

Note that, also in this example, the protrusion locking portion 49 is provided with an intermittent cutout portion 51 to externally communicate with the separated space 19 to form the above-mentioned equal pressure space. Since the remainder does not change, the same reference numerals are given and the description thereof will be omitted.

By the way, in the embodiment shown in FIG. 7, irrespective of the above example, for example, when the stone exterior panel has a single upper and lower stage, both of the reinforcing holders are replaced by the window sash frame, and one of the upper and lower sides is replaced. Whether to substitute or to substitute both depends on the installation mode of the stone exterior panel.

When using this window sash frame, if it is generally made of an aluminum alloy, it may be desirable to thicken its cross-sectional shape or insert or attach a reinforcing iron core. As with the one in FIG. 6, this can be done by appropriate selection.

In addition, the liner for entrance / exit adjustment of the embodiment shown in FIG. 7 may be added as necessary in each case. Therefore, in FIG. 7 as well, instead of the anti-electrostatic material (made of stainless steel, It is also used as an anti-electrostatic material) or together with this liner. When a liner is used, it is convenient to use it as thinly as possible and stack as many sheets as necessary.

On the other hand, the reinforcing base frame in the present invention is made of square steel, but it is arbitrary whether or not a vertical or horizontal middle frame is used for this, and therefore, for example, the outer shape is square and the inner side is a grid. It may also be a shape or the like.

Further, in the present invention, since a separation space is provided and is made an isobaric space communicating with the outside, it is desirable to seal between the high-strength blocking panels and between the window sash and the like. As shown in the above embodiment, it is convenient to select the proper position for the packing and interpose it, but it is also possible to use other sealing means such as a sealing material, while the blocking high-strength panel is used together. Alternatively, this and the window sash frame may be directly fitted and brought into contact with each other.

Further, in the present invention, the stone exterior panel is supported by the reinforcement holder or the window sash instead of the reinforcement holder, but it is not obstructed to add additional auxiliary support or fixing means by metal fittings or the like as necessary. Since the engraved groove provided in the stone exterior panel may receive and lock the tip locking portion of the reinforcing holder and the ridge locking portion of the window sash frame, it may be determined according to their length and shape. Therefore, for example, it may be formed into a rectangular thick groove.

As described above, the present invention provides a high-strength barrier panel or a part thereof,
Including the stone exterior panel and its engraved groove, reinforcing holder and tip locking part, window sash frame and ridge locking part, each specific material, shape, size, structure, fixing means of these or other things Additions to these and the like can be appropriately modified and implemented without departing from the spirit of the invention, and the invention is not limited to the above examples and explanations.

[Effects of the Invention] The present invention has the following effects because it has the configuration described in the summary of the invention.

Since the steel barrier has surface strength, it is difficult to deform during transportation of the curtain wall, installation, and after installation.

Since the steel shielding wall is watertight and the sealing base is provided on the side facing the adjacent stone curtain wall unit of the reinforcing base frame, rainwater that has invaded from the stone itself or between the stones is unlikely to enter the body.

Since cement, mortar, etc. are not used to fix the stone material to the reinforcing base frame, the manufacturing time of the curtain wall unit is shortened by the hardening time.

Further, since the stone material is fixed to the reinforcement base frame by the reinforcement holder, the stone material can be replaced.

Further, since the stone material is attached to the high-strength panel in a flexible structure by the reinforcing holder, the stone material is flexible with respect to the displacement of the relative position due to the difference in thermal expansion, and can withstand long-term use.

Further, since the back surface of the steel shielding wall is smooth, a fireproof material or the like can be easily attached.
