Description

The present invention relates to a heat insulating frame body having fireproof and rust-proofing functions, in which notches and heat insulating material fasteners are used in the frame body on the outdoor surface of a rectangular steel frame.

The window frame of a typical sash is composed of an upper frame, a lower frame, and a vertical frame made of metal such as aluminum that has high thermal conductivity. Since the frames of such windows and doors are made of metal, heat is easily transferred between indoors and outdoors, and when there is a large temperature difference between indoors and outdoors, condensation and heat loss occur on the indoor surfaces of the windows and door frames. For this reason, the exposed indoor surfaces of window and door frames that are exposed to the indoor side when the shoji and doors are closed are coated with insulating materials with low thermal conductivity such as inorganic materials and resin, and metal windows, There is a demand for an insulating frame that prevents the door frame from coming into direct contact with the indoor air or lowers the heat conductivity of the metal frame, thereby suppressing condensation and heat loss on doors and windows.

On the other hand, metal materials are used for the door frames of entrances and exits in apartment buildings in cold or high-temperature regions, as well as in coastal areas. is expected. Particularly in cold or high-temperature regions, outside temperature is transmitted indoors, resulting in large energy losses during cooling and heating, and it is desirable to prevent heat loss at entrances and exits or openings and closings as a measure against global warming. Various measures have been taken to prevent condensation on aluminum sashes, but aluminum is not used for large doors due to its strength, and steel is not used for entrances and exits in apartment buildings. A manufactured door and frame is desired. At present, no heat insulation measures have been taken for steel doors, large-area entrances and exits, or opening/closing devices.

Conventionally, in window frames for general living rooms, when the indoor side of the vertical frame (inside the nail fin of the column) is made of resin profile, when attaching the blind end to the angle part of the resin profile of the vertical frame. , it is necessary to cut out the angle portion until it remains in the form of a plate, which makes it weak in strength and easily damaged. For this reason, there was a risk of damage within the packaging during storage or damage during transportation. Frames made of resin or wood are preferable in terms of heat insulation, but they still have problems with fire resistance, and frames made of metal have problems with rust or heat insulation.

In general, in order to simplify the installation of fittings in houses, door frame structures are designed to increase rigidity, prevent deformation caused by interstory displacement of buildings during earthquakes, and provide door frame structures that are easy to install. It consists of an inner frame and an outer frame. A first reinforcing member is slidably installed in a first groove formed on the outer periphery of the inner frame, and a first reinforcing member is slidably installed in a second groove formed on the outer periphery of the outer frame. Two reinforcing members are installed. The door frame structure is indirectly attached to the wall surface via an attachment angle fixed to the first reinforcing member. The door frame structure does not follow the interstory displacement of the wall surface caused by lateral shaking during an earthquake. There have been reports of a device that minimizes deformation of the door frame structure and makes it possible to open and close the door even in an emergency. (See Patent Document 1)

In addition, the door is not only non-combustible and flame retardant, but also has heat insulation and heat retention properties, ensures sound insulation, and is light in weight. The surface plate is made of a steel plate with a thickness of 0.6 to 1.0 mm, and the steel plate that holds the surface plate around it is composed of a steel plate with a thickness of 1.4 to 1.8 mm. A lightweight, soundproof, and fireproof door has been proposed that has a structure in which the face plate is attached to each other and the inside is filled with inorganic rock wool 35 to 45 mm thick in a sandwich shape. (See Patent Document 2)

Furthermore, in order to prevent the strength of the angle portion of the resin frame that makes up the vertical frame from decreasing, we are providing a heat insulating frame for invisible mounting that can be supplied at low cost without using a complicated component structure. A vertical frame made of an aluminum profile and a resin profile on the indoor side, and a blind made of an aluminum profile and a resin profile are formed. The interference portion of the resin profile at the blind contact portion of the vertical frame is formed as a plurality of cut portions. It has been proposed to form a notch in the resin profile on the blind side at a portion where it interferes with the resin profile on the vertical frame side. (See Patent Document 3)

In addition, by preventing co-rotation when frame members are connected, it is possible to prevent misalignment between the frame members, and also to prevent gaps between the frame members from being exposed. As a timber joint structure, in a frame material joint structure that interconnects an upper stile, which is a first frame material, and a vertical stile, which is a second frame material, the connection portion between the upper stile and the vertical stile is It has been proposed to provide a joint cover that is fixed to either the upper stile or the vertical stile and substantially abuts at least the other side surface. (See Patent Document 4)

When insulating windows and doors, the members connecting the indoor frame material and the outdoor frame material are difficult to melt even when heated. A frame body in which an outdoor frame material disposed on the outside is connected by a heat insulating material, a cover member provided on the frame body to cover the heat insulating material, and a space between the frame body and the cover member when heated. It has been proposed to have a heated foaming material that foams. (See Patent Document 5)

Aluminum sashes, aluminum windows, etc. are being widely considered as insulation frame materials, but we are considering materials that are fireproof and rust-proof, including strength, and have enhanced insulation effects using steel frame materials. There are almost no suggestions.

Metal materials are used for large entrances and exits in housing complexes in cold or high-temperature regions, as well as in coastal areas, and for the doors and frames of openings.In addition to being fire-resistant and rust-proof, metal materials are also heat-insulating. is expected. Particularly in Hokkaido, other cold regions, Okinawa, and other high-temperature regions in Japan, the outside temperature is transmitted indoors, resulting in large energy losses in cooling and heating, and it is important to prevent heat loss at entrances, exits, and openings. This is also desirable for global warming countermeasures. Various measures have been taken to prevent condensation on aluminum sashes, but aluminum is not used for large doors due to their strength, and instead steel doors and frames are used. Currently, no heat insulation measures are taken for large-area entrances and exits or opening/closing devices that are made of steel doors and frames.

However, when it comes to heat-insulating covers, parts that are in close contact with the metal window frame and the mounting pieces of the window frame may be damaged during winter nights or when there is a large temperature difference between indoors and outdoors. Since the insulating cover is cooled by the frame, there is a risk that warm air from inside the room may come into contact with the cooled insulating cover and cause condensation. On the other hand, if the mounting piece that tightly contacts the insulating cover is removed from the frame of a window or door, the insulating cover cannot be reinforced with the mounting piece, and the insulating cover may bend, making it difficult to place it accurately. There was a problem. It is expected that the material will be made only of metal, especially steel, which has strong and fire-resistant properties, and will have improved insulation and rust prevention effects. An object of the present invention is to provide a heat insulating frame that can improve fire resistance and rust prevention performance using stainless steel material, steel material plated with Zn, AL, and Mg components, and has a method for improving heat insulation performance. .

A hole is formed in the plate-like surface of the closing plate material, and serves as a reinforcing material for the joining frame of the first frame and the second frame, and the first frame on the outdoor surface is connected to the upper frame, and The groove structure has two rows of cutouts on the outer peripheral surface of a substantially S-shape along the left and right vertical frames, and a recess into which an airtight gasket material can be inserted is located at the center of the groove structure. On one side of the side surface and on the bottom surface, slotted slot-like cutouts of rectangular surfaces are provided in a phase-differential manner, and the frame is composed of a first frame body and a second frame body. This is a heat-insulating frame body with fireproof and rust-proofing functions, in which a reinforcing material shaped to close the body is firmly fixed, and a heat insulating material is fitted between the closing plates. The heat insulating material used is an inorganic material or a heat-resistant resin material, preferably calcium silicate, glass wool, silica, or resin/rubber containing fluorine.

The elongated hole-shaped cutouts on the rectangular surface are arranged in two rows with a phase difference pairing along the upper frame of the first frame on the outdoor surface and the approximately S-shaped outer peripheral surfaces of the left and right vertical frames. The missing part is a notch, and the width is less than half the width of one side of the door stop recess and the bottom, and rectangular slots with a length of 100 to 500 mm are arranged at equal intervals. The length ratio of the slotted elongated hole and the uncut part is set to 10:1 to 10:5, and the arrangement of the notches on one side of the side and the bottom is such that each uncut part is aligned with the opposite notch. They are arranged in opposite rows at the center to prevent linear heat conduction, and the doorstop groove structure can be filled with an airtight gasket.

In the doorstop part of the groove structure, which has a missing part in the form of two rows of notches along the longitudinal direction of the doorstop length in the approximately S-shaped outer peripheral upper frame of the rectangular steel fittings frame and the left and right vertical frames, The first frame on the outdoor surface having a substantially U-shaped joint is made of plated steel containing zinc, aluminum, and magnesium, or stainless steel, with a thickness of 1 to 3 mm, and includes an upper frame and a left and right frame. It has a notch in the doorstop recess that exists on three sides of the vertical frame, and the length and area on one side and the bottom are 50 to 100 mm width x 4900 to 5400 mm length, 2450 to 5400 cm2 area, and 15 to 20 mm width x 4900 mm. The first frame has a length of ~5400mm and an area of 735~1080cm2, and the area ratio of the notch on the side surface is 3~30%, and the area ratio of the notch on the bottom side is 30~60%. Insulation according to JIS standards can be achieved by fitting insulating plates made of inorganic material or heat-resistant resin between the reinforcing materials used to secure the frame body and the second frame body. Thermal conductivity of heat grade H-3 is set to 3.49 W/m2·K or less.

The connecting reinforcing material, which is a closing plate in the form of a U-shaped plate, is smaller and has the same shape as the cross section of the joining frame constituted by the first frame and the second frame. It has a U-shape in cross section, and is a member that can be reinforced so as to close the entire component frame, and a heat insulating material is fixed to the contact surface with the back of the frame on the outdoor side. In order to prevent heat conduction, the plate-shaped surface has a structure in which several holes are formed on the surface, and the first frame and the second frame are connected to the frame and the closing material. It has a frame structure for attaching to a door, in which the joint frame is tightly reinforced and the joint frame is strongly reinforced. In addition, the number of reinforcing materials in the form of plugging material is fixed in a number that can compensate for the weakening of the frame due to the loss of the cross section of the first frame, and a filler is provided between the reinforcing materials to improve heat insulation performance and fire resistance performance. is attached.

A baking-painted steel material with a thickness of 1 to 3 mm is used, a locking device installation opening is opened on the locking side of one vertical frame on the outdoor side, a hinge is provided on the other vertical frame on the outdoor side, and the above-mentioned An airtight gasket is attached to the surface where the door stop of the first frame comes into contact with the door, and the surface material of the fire-resistant and heat-insulating door and the heat-insulating first frame door stop are brought into close contact with each other. There is

For resin doors used in hotels, condominiums, and large public facilities, it has become difficult to obtain fire protection performance for 60 minutes in combustion tests based on ISO standards at an average temperature of about 900°C. In order to improve the fire protection performance of thermosetting resin doors, as mentioned above, materials such as phenol and melamine thermosetting foams, unsaturated polyester resins, inorganic materials, calcium carbonate, glass fiber boards, etc. Carbonizes and prevents flame from penetrating. In addition, it is possible to provide a steel frame resin door that is lightweight and has increased decorativeness, and if stainless steel is used for the frame, weather resistance is also increased. If this can be confirmed through a 60-minute fire resistance test of a steel frame resin door at a public institution, it will be possible to provide a steel frame resin door that has the same fire resistance as fireproof/fireproof doors made of steel. To provide a fire-resistant heat insulating material other than a steel door that is as light as possible, has simple decoration, exhibits extremely excellent fire prevention performance, and can be significantly reduced in cost.

As a result of conducting a 60-minute fire resistance test using a test piece with a combination of a stainless steel frame and a resin door, it passed both the indoor heating test and the outdoor heating test, confirming that it had the performance of specified fire prevention equipment. Ta. In the fire resistance test, which reached a maximum temperature of 945 degrees, no deformation of the metal parts on the non-heated side or a large amount of radiant heat from the resin door was detected, indicating that the door had the insulation performance of a resin door. Furthermore, we were able to confirm the thermal insulation performance of the steel frame resin door through a thermal insulation performance test.

Metal materials are used for the frames of large entrances and opening doors in apartment buildings in cold or high temperature regions, as well as in coastal areas, and due to environmental concerns, metal materials are not only fire-resistant but also rust-proof. There is a demand for materials with high thermal insulation properties. In regions such as Hokkaido and Okinawa, in cold weather in the middle of winter or hot weather in the middle of summer, it is difficult for outside temperature to be transmitted indoors, reducing energy loss in cooling and heating, and reducing heat loss at entrances, exits, and openings. It was possible to prevent loss and became an effective measure against global warming. In addition, by combining this heat-insulating stainless steel or plated steel frame with a heat-insulating resin door or wooden door, heat management becomes easier through heat insulation measures around large-area entrances and exits.

By using a heat insulating frame with fire and rust prevention functions, we can achieve the required fire and rust prevention performance of metal doors, allowing entrance and exit fittings to operate stably and effectively for long periods of time in regions with harsh climates. It had excellent fireproofing performance, was easy to construct, and could also be used as a rust-proof door. It can also be used for fire-resistant resin doors and fire-resistant wooden doors other than steel doors, making it possible to effectively control indoor temperature. In the case of heat-resistant resin doors, they are manufactured using materials that are highly decorative and can prevent salt damage, and an insulating frame with fire and rust prevention functions can be effectively used.
