Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for pre-attaching glass to a curtain wall panel.

[0002]

2. Description of the Related Art In a building having an outer wall curtain wall structure, two methods have been conventionally used for attaching glass for an outer wall to a curtain wall panel (hereinafter abbreviated as a panel). One of them is to attach the panel to the outer wall first, and then use the gondola etc. to fit the glass into the panel from the outside. This is a method of fitting it to the panel and then lifting it using a hoist crane or the like and mounting it on the outer wall. The latter is called the glass pre-attachment method.

The work procedure of the conventional glass pre-attachment method will be described with reference to FIG. Panel, glass, fireproof board,
Each of them is hoisted and stocked to an appropriate floor, and work such as installing glass is performed on this floor. Each member differs depending on the installation location, but the panel weighs 140 kg.
~ 215 kg, glass 50 kg-75 kg, fireproof board 32 kg-40 kg, assembled curtain wall unit (hereinafter abbreviated as unit)
The total weight is 450 kg to 600 kg. Therefore, a forklift is used to move each member from the stock position to the assembly position.

The assembly of the unit starts with the work of carrying the panel to the position of the workbench by a forklift and placing it on the workbench in a horizontal state. Next, the glass is carried in, and the work of fitting it from the upper surface side of the panel is performed. Incidentally, in the construction method in which the glass and the fireproof board are simultaneously attached to the panel at the site, the fireproof board is attached prior to the glass attachment. In the conventional method described above, the glass mounting surface of the panel on the gantry is located on the upper side (side facing the ceiling).

In the above-mentioned work, the back side of the glass is hidden while the glass is placed on the panel. Therefore, it is necessary to perform a cleaning operation such as wiping the back side of the glass before the work of attaching to the panel. There is.

After the glass is attached, the unit is transferred to a curing stand and once stored in the stockyard for curing the pitch seal. After the curing period has passed, it is moved to the window side when the panel is hung, lifted using a hoist crane, etc., and pulled out to the outdoors. In the conventional construction method, since the glass surface of the lifted unit is located on the building side, it is necessary to invert the unit prior to mounting it on the outer wall. As mentioned above, the reversing work of the suspended unit is 450K for the entire unit.
It is very dangerous because it weighs as much as g to 600 kg.

[0007]

In the conventional glass pre-attachment method described above, the glass is fitted from above into the panel placed horizontally on the workbench, so that the forklift carries it from the stock position. It is necessary to lift the broken glass horizontally above the panel. This work involves lifting and moving a heavy and fragile glass and setting it on the panel, which requires skillful techniques and is also inefficient in work. Moreover, in this conventional glass pre-attachment construction method, since the glass is on the upper side in the state of being attached to the panel, there is a high risk of damage to the panel after the glass is attached while the panel is stocked for curing the seal. Further, as described above, in the state where the glass is set on the panel, the back side of the glass is hidden, so the cleaning work on the back side of the glass must be performed before it is hung on the panel to fit the glass, It is necessary to perform the cleaning work as an independent process before the glass mounting work, and it is necessary to take care not to stain it until the glass is fitted after starting the mounting work, so that the working efficiency is extremely poor.

Furthermore, since the unit assembled by the conventional construction method has the glass on the upper side, when the unit is pulled out to the outside of the building, the glass surface is facing the side of the building, and hence the outer wall. It is necessary to invert the hoisted unit so that the glass side faces outward to attach the unit. Therefore, in a narrow space, the unit may hit the surrounding area or the neighboring building and damage it.In addition, since it is a work at a high place, it is dangerous and requires careful work, resulting in reduced work efficiency. It is a big factor to make. In some cases, since the building is not sufficiently separated from the neighboring building, the reversing work itself may be difficult, which may be a hindrance.

As is clear from the above, the present invention is a glass that enables the work of attaching glass to the panel and the work of attaching the unit to the outer wall of the building with high work efficiency and safety. The purpose is to clarify the pre-construction method.

[0010]

In order to achieve the above object, a method of pre-attaching glass to a curtain wall panel according to the present invention is a glass moving carriage for a curtain wall panel placed horizontally on the upper surface of an assembly frame. The glass placed in a substantially horizontal state is slid in a horizontal direction from the glass moving carriage, and is inserted and attached.
In addition, in this construction method, the glass was attached to the curtain wall panel at the building construction site, and the curtain wall panel on which the fireproof board had already been attached was placed horizontally on the glass moving carriage. Slide the glass horizontally from the glass moving trolley to the lower position of the fireproof board, insert the glass into the panel with the glass surface side facing down, and attach the glass to the periphery of the frame. A curtain wall panel provided with an insertion part for inserting glass is used, a movable assembly frame is used, and movement and height adjustment are possible, and glass is horizontally slid on the upper surface thereof. Each is characterized in that a glass moving carriage provided with a mechanism for making it work is used.

[0011]

DETAILED DESCRIPTION OF THE INVENTION The glass pre-attachment method of the present invention will be described in detail below. Incidentally, the present invention is not limited to a panel of a type in which a plate glass is incorporated in a metal frame body, a panel of a type in which all or a part of the frame body is made of synthetic resin, instead of the plate glass, all or a part thereof is used. It is also applied to a panel made of synthetic resin.

A: On-site loading of materials such as panels and glass The curtain wall in this embodiment is a unit having glass on the outside and a fireproof board on the inside. In a preferred embodiment, the curtainboard Although the panel mounting is done in the factory and only the glass is installed in the field, the present invention also includes a mode in which the refractory board is installed in the field.

B: Carrying in and setting the panel 20 (see FIG. 1) The panel 20 placed on the stock mount (pallet) 10 is
It is carried in by using a forklift and set in a horizontal state on the assembly stand 11. In this state, the refractory board 21 is located on the upper side, and the part to which the glass 22 is attached is located on the lower side.

C: Carrying in the glass 22 (see FIG. 1) The glass 22 is placed on the glass moving carriage 12 with the back side facing up and carried to the side of the assembly frame 11. The glass moving carriage 12 is provided with a mechanism for sliding glass on the upper surface, for example, a plurality of rollers, is movable by the casters of the legs, and has a structure in which the height can be adjusted.

D: Adjustment of Position / Height of Glass Moving Carriage 12 The position / height of the glass moving carriage 12 is adjusted so that the glass 22 faces the panel 20 at a right angle in a substantially horizontal state. The height may be adjusted only once at the beginning.

E: Cleaning of the glass 22 The back side of the glass 22 is cleaned. The cleaning work should be performed at any time from the time when the glass 22 is placed on the glass moving carriage 12 to the time when it is inserted into the panel 20, since the indoor surface of the glass faces upward and is horizontal on the moving carriage. However, it is preferable to perform it immediately before inserting it into the panel 20 because it is less likely to become dirty after cleaning. In a particularly preferred embodiment, the fireproof board is attached before the glass is attached, and since the back surface of the glass (inside surface of the room) cannot be operated after the glass is inserted into the panel, cleaning can be performed immediately before the glass is inserted. This is very effective in preventing dirt.

As described above, in the conventional glass pre-attachment method, since the back surface of the glass 22 is located on the lower side, the back surface cannot be cleaned after the glass 22 is attached to the panel 20, 1 only for this work
It requires steps, and it is necessary to take care not to stain the cleaned surface during the glass mounting work, and these points also cause a reduction in work efficiency.

F: Insertion / temporary fixing / curing of the glass 22 The glass 22 is slid in a substantially horizontal state by using a roller provided on the upper surface of the glass moving carriage 12 and inserted into the panel 20, and the opcell backer is inserted.・ Set the glass weight receiving neoprene rubber, glass fixing neoprene rubber, glass edge curing material, pitch seal, etc. to temporarily fix the glass.

In order to enable the above-mentioned glass 22 to be inserted into the panel 20, the structure of the panel 20 is such that an insertion opening (opening) for inserting the glass is formed in the peripheral portion of the frame body of the panel 20.
Is prepared. In the conventional construction method, since the glass is attached from the front side (back side) of the panel, there is no restriction on the glass insertion in the peripheral portion of the frame body of the panel 20.

At the time of inserting the glass into the panel, at the contact portion between the panel and the glass so that the glass can be smoothly inserted,
Place a sliding material such as a Teflon sheet. This slip material is
It can also be used as an auxiliary material to easily and finely adjust the glass during image adjustment at the final stage of construction. It should be noted that in a preferred embodiment, the refractory board 21 has already been attached to the panel 20 at the factory and the glass 2
2 is below the refractory board 21 and means for protecting the glass in particular during the curing period of the pitch seal can be omitted.

In the conventional glass pre-attachment method, the glass 22 is used.
Since the method of fitting from the upper surface side of the panel 20 is used for attaching the glass 22 to the panel 20, it is necessary to lift the glass 22 up to the upper side of the panel 20. This is a method in which the glass 22 is inserted through this opening and the glass 22 is inserted through this opening. Therefore, it is not necessary to lift the glass 22 simply by sliding the glass 22 on the glass carriage 12 in the lateral direction.

Therefore, while the conventional glass pre-attachment construction method requires 3 man-crafts including the forklift operator, the method of the present invention allows work with 1 man-craft, which is not only highly efficient. However, there is an advantage that work safety is extremely high. Panel 2 with the glass temporarily fixed
The second one uses a forklift to carry it to a curing space for curing.

G: Preparation for Mounting Unit 23 (See FIG. 2) The cured unit 23 is carried to the mounting position (outer wall side) using a forklift. The unit 23 assembled on the assembly frame 11 may be cured while being mounted on the assembly frame 11 and carried to the mounting position.

H: Lifting / fixing of the unit 23 (see FIG. 3) The unit 23 is hung outside using a hoist crane or the like, the panel is set from the outside to a predetermined position, and fixed inside the building. When lifting the unit 23, the unit 23 may be lifted slowly while the forklift is being loaded, or the unit 23 may be placed on a moving carriage. When using a forklift, an intermediary jig is used to protect the lower end corners of the unit 23. Further, in a mode in which the unit 23 is carried to the assembly position while being placed on the assembly frame 11, the unit 23 is directly lifted from the assembly frame 11.

In the conventional glass fronting method, the unit 23 is assembled with the glass positioned on the upper surface and carried to the mounting position. Therefore, when the unit 23 is hung outside, the glass surface faces the outer wall of the building. . Therefore, in order to fix the unit 23 to the outer wall, it is necessary to rotate the unit 23 in a suspended state and direct the glass surface to the outside. This work is performed by the unit 23
Is very heavy and easily affected by wind,
Not only is it extremely dangerous, but panel 2 when it hits the surroundings
Not only 0, but also the glass 22 may be damaged, and the work must be performed carefully, which causes a decrease in work efficiency.

According to the construction method of the present invention, the suspended unit 2 is used.
No. 3 has an advantage that the fixing work can be performed immediately without performing the above-mentioned reversing work, and therefore the work can be performed safely and with high efficiency.

I: Image adjustment / main fixing of glass / cleaning Image adjustment is performed to correct the glass position, then main fixing is performed, and the outer wall surface is cleaned.

[0028]

The glass pre-attachment method according to the present invention has the following advantages over the conventional method.

Since the glass 22 can be inserted from the lateral direction into the panel 20 placed horizontally on the assembly stand 11, the glass 22 can be assembled as in the conventional method.
It is possible to perform work safely and efficiently without the need to lift.

As a result of the above, when the glass 22 is attached, it is possible to perform the attaching work while the glass is being placed on the glass moving carriage 12, which can greatly contribute to the safety and efficiency of the work.

At the working stage, since the glass 22 is horizontal on the dolly and the back side is facing upward, the back side of the glass 22 can be easily cleaned immediately before mounting, and the cleaning is properly performed. It is possible. The conventional construction method requires one special working step for cleaning the back surface of the glass 22, and according to the present invention, this step can be omitted, so that the working efficiency is improved.

Since the fireproof board 21 is preliminarily attached to the indoor side of the panel 20, the glass 22 is located below the fireproof board 21 when the glass 22 is incorporated into the unit 23, and the glass 22 is located in the conventional construction method. As described above, since it is not exposed to the upper side, there is little risk of damaging the glass 22 in the steps after curing, and no special measure for protecting the glass 22 is required.

When the unit 23 is hung and attached to the outer wall portion, the glass 22 is prepared in a state of being positioned on the lower side in the construction method of the present invention. Since it is hung in a state facing the front, it is not necessary to invert the unit as in the conventional construction method, but the fixing work can be performed immediately, which is beneficial for the safety and efficiency of the work.
