DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a structure of a building, and more particularly to a structure of a mesh-like roof surface of a building, and mainly relates to a steel building having an insulated roof.

[0002]

BACKGROUND OF THE INVENTION In recent years, widely stretched metal and metal screens and other different types of mesh-like members have been proposed for use in constructing building walls and ceilings. . In some examples, US Pat.
No. 4, a cement material or a plastic material is used for a mesh-like member. In addition, as in the technology disclosed in U.S. Pat. No. 2,148,281, a mesh-like member is used to reinforce and hold a heat insulating material, and in U.S. Pat.
No. 47,436 has proposed a wire mesh member reinforcing material.

[0003] In US Pat. No. 3,506,746, a net supported by pillars attaches plaster or the like to reinforce a door or window portion when building a structure to be made later. It is used as a support material. U.S. Pat. No. 545,301 discloses a method of constructing an arched roof by adding concrete or cement to a braided member of corrugated wire supported by beams.

Further, US Pat. No. 4,557,092 discloses a blanket-like heat insulating material having a high-strength cotton cloth layer fixed to a fibrous protective material for preventing an object from falling. ing. However, it has been difficult to impart sufficient rigidity to a member that prevents a heavy object from falling. Finally, as in the technique disclosed in U.S. Pat. No. 3,791,089, a flexible material is used to support the ceiling insulation when the ceiling structure falls. There is something like that.

[0005]

However, in each of the above-mentioned conventional examples, there is a problem that a worker working at the site cannot take a sufficiently safe action when an accident occurs. Also, there has been no simple, durable and groundbreaking way to hold glass fiber blanket-like insulation on the roof of a steel building.

When constructing a roof, accidents sometimes occur when workers fall off the roof under construction or when objects fall on workers under the roof. Therefore, it is standard practice to provide safety nets or other types of sheet metal beneath the roof mounting to protect workers, or to connect workers to the foundations of the building. And a mandatory measure.

Another problem is that of dropped tools.
Safety nets that are designed to catch fallen workers usually have small tools, bolts, fasteners,
A mesh large enough to allow other building materials to pass through; for example, 15.24 cm (6 inches)
It has a mesh on all sides. Conventional measures for hooking such a tool include providing another smaller mesh net below the safety net.

The method of keeping the workers connected is temporary but effective. However, when one worker is neglecting to use the safety strap or moving the safety strap, workers on the roof and below are exposed to dangerous conditions. . It is a good idea to tie tightly so that it does not come off, or not to move hard. A binding method similar to an airbag system in a vehicle, such as the former case, is preferred over one similar to a seatbelt. However, the latter case cannot be avoided.

We have shown that a very simple, effective and durable insulated roof is constructed of strong mesh fibers which avoid serious accidents caused by falling tools and structures. Discovered and also found to form a durable part of the roof. Accordingly, the present invention has been made in view of the above-described problems, and has as its object the purpose of a worker falling down from a roof under construction or a tool or structure falling to a worker under the roof. Therefore, it is an object of the present invention to provide a mesh-like roof surface structure for preventing the occurrence of an accident caused by the accident.

[0010]

In order to solve the above-mentioned problems and achieve the object, the structure of the mesh-like roof surface of the present invention is as follows.
A roof structure comprising a plurality of lateral beams, a plurality of hazes extending perpendicularly to the beams, maintaining a constant interval, and a plurality of hazes parallel to each other, and laying horizontally on the haze. And a supported waterproof uppermost layer, and a non-metal mesh member supported and spread over the haze at a lower portion of the waterproof uppermost layer. .

In addition, at both edges of the edge of the roof and the mesh-like member reinforced by a pillar supporting the edge of the roof, the pillars spread in parallel to the haze. It is characterized by having. Also, at the edge of the building,
At both ends of the mesh-like member reinforced by the gables along the edge of the roof, the gazes are vertically provided to the haze.

[0012] Further, a heat insulating material layer is provided in a portion above the mesh-like member. The heat insulating material layer is mainly made of wood.
Further, the heat insulation material layer is a hard plate material. Further, the heat insulating material layer is a blanket-like member that is compressible in terms of material.

[0013] The mesh member is characterized in that it is loose in material from the haze.
Further, the mesh-like member is characterized by being bent at least about 15.24 cm (6 inches) between the mesh and the haze. In addition, a rigid sheet metal deck is provided above the mesh member and below the heat insulating material layer.

[0014] The mesh member can withstand a drop from a height of 0.9 meters (3 feet) and have sufficient strength to withstand a weight of 227 kilograms (500 pounds). It is characterized by having. A method for safely constructing an insulated roof, comprising vertically erecting a roof base support member including a haze arrangement, and relaxing the haze with a rigid non-metallic mesh material. Laying the rigid non-metallic mesh-like member around the roof base support member around the periphery of the rigid non-metallic mesh-like member. The method is characterized by comprising a step of protecting with a layer and a step of protecting the heat insulating material with a waterproof panel.

[0015] The laying and protecting step may include drawing the mesh member laterally from the roll on the ground surface onto the roof, and ending the mesh member with one end of the roof. It is characterized in that it reinforces the part and its own end of the other mushroom. Further, the mesh-like member is inserted with a slack portion having a sufficient length to make a slack of at least about 15.24 cm (6 inches) between the hazes.

Further, before the step of laying the waterproofing material,
Arranging a corrugated metal panel layer above the mesh member and reinforcing the panel with the haze.

[0017]

As described above, since the structure of the mesh-like roof surface according to the present invention is constituted, a plurality of lateral beams and a beam extending perpendicularly to the beams are maintained at a constant interval. A plurality of parallel hazes, laid laterally on the haze, and a supported waterproof top layer, and at the lower part of the waterproof top layer, the haze spreads over the entire surface and is supported. The non-metallic mesh members provided provide excellent safety, preventing workers from falling off the roof under construction or accidents caused by tools or structures falling to workers under the roof. A reticulated roof surface structure can be configured.

[0018]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIGS. 1 and 2 show a frame 1 composed of a plurality of sets of vertical components 12.

The lateral component beam 14 is a metal member having a Z-shaped cross section. The ends seen at both ends of the building are closed by an angled gable 18. Saw column 20 at the edge of the roof
Each extend parallel to the haze 16. Noki support 2
Numeral 0 is a member having a U-shaped cross section whose side surface is preferably open toward the center of the roof.

FIG. 2 is a perspective view showing the mesh-like member 22 directly covered on the roof directly above the haze 16. Preferably, the reticulated member 22 is a net woven of a polyester open fabric forming a 0.5 inch square open space, made of fire retarded polyvinyl chloride. Surface treatment. The reticulated member 22 has a height of 0.9 meters (3 feet) above the haze 16 from 91 kilograms (200 pounds) to 1 inch.
It is long enough to accept a person weighing 36 kilograms (300 pounds) if it falls. Furthermore,
To improve safety, the net must have passed a 227 kilogram (500 pound) drop test and passed.

The mesh member 22 weighs 74 grams (2.6 ounces) per square centimeter (yard) and satisfies the required strength described above. Also, the mesh member 22 is sold by Bay Mills Limited, Ontario, Canada,
Rolls of 2.2 meters (7 feet) to 3 meters (10 feet) wide are available. The product number is
"Bayex Product QX-2220 / V"
It is.

The spacing between the standard buildings (at a distance from the beams) is 30 feet (9 meters) wide. The ends are stitched together in two rows, using some width of the member, to cover such an area and to be overlapped on both sides of about 0.3 meters (1 foot). They are connected by a hooking member having an end-to-end hooking strength equal to its own strength. The edges of the member, when received from the manufacturer, have a woven end 30
(See FIG. 4). In addition, the end portion where the member reaches is reinforced by being sewn with the fiber tape 32 in a ball shape. The newly constructed end is
Similarly, in the field, it is reinforced with selectable reinforcing ropes.

As shown in FIG. 5, the rolls 40 of the mesh member 22 are previously joined together from thin rolls.
Then, before being rolled up, they are superimposed several times the size of an easy-to-use area, and are placed side by side on the building. The overlapping edges of the superimposed mesh are raised above each of the sawing struts so as to lie in the distant strut haze.
The mesh-like member 22 is in an unfolded state.
If the blanket-like heat insulating material 50 is put on the mesh-like member 22, there is a slack (see FIG. 8) so as to bend by about 15.24 cm (6 inches) with the haze. Will be. Otherwise, the slack must be removed.

As shown in FIG. 3, the mesh-shaped member 22
The tip and the base are sandwiched between one of the support pillars and each of the metal straps 34 having a slightly raised angle. The strap 34 is pulled against the component by a pointed screw 36 provided every 0.3 meter (one foot). The lateral edges of the uncovered members are connected to the gable angles in the same manner as described above or by plastic fasteners 38 (see FIG. 4) extending through the holes at equally spaced angles 18. Have been.

If a rigid heat insulating material is used, the sheet-like metal with the corrugated panel 42 is joined by screws, rivets or spot welding. The panels 42 are then overlaid by a rigid insulation layer, such as a "Thermax" panel 44 from Serotex Corporation (see FIG. 6) or a thermal insulation 46 "CMR-24" from Butler Manufacturing (see FIG. 7). . The insulation is finally covered by a waterproofed top layer. If an insulation board called "Thermax" is used, for the top layer,
It is desirable to use felt pieces or saturated bitumen. Another is the "CMR-2", which has a top layer (sheet-like metal layer) for all weather, already assembled in rigid insulation.
4 "insulation panel, reinforced by special clips that allow the roof to be wider than it should be. Details of this clip can be found in U.S. Pat.
3,760.

When the blanket-like heat insulating material 50 is in the inserted state as shown in FIG.
It is placed loose. By being placed loose, the fibrous material can be from 2.54 centimeters (1 inch) to 15.24 centimeters (6 inches) when placing the insulation, depending on the thickness of the insulation below the haze thickness. It forms a rain gutter with a depth of about inches. Mesh member 2
Numeral 2 supports a blanket-like heat insulating material from below. Finally,
An all-weather metal roof panel 48 is placed on the insulation and sewn together to connect the haze length laterally.

In the present invention, the safety of the worker can be obtained with a minimum effort, and it is not necessary to move the mesh member. The service life of the roof will be prolonged and, in the future, it will prevent workers from falling out of the skylight (windows on the ceiling) or holes in the roof.
Furthermore, the mesh-like member is designed to spread below the skylight without obstructing its function, to be less noticeable, and to transmit light.

The advantage of the mesh member is that it protects the thermal insulation layer from moisture as well as the thermal insulation support member. In addition, the mesh member is behind the glass fiber insulation,
It is invisible from outside. Therefore, it is harmless to the heat insulating material and the appearance is improved. By inserting the mesh-like member, safety is ensured even if the heat-insulating material is not inserted on a blanket-like heat insulating material, a hard heat insulating plate or plywood, or even a mesh-like member.

The present invention cannot be protected, of course, if an operator falls off the edge of the building. And at this stage, The Occupation Safety and Health Administrat
ion; abbreviated to OSHA (Occupational Safety and Health Agency) approved parts and is being treated to protect it from falling even in the center of the building. Needless to say, the above-mentioned matters have been improved as compared with the conventional case. Where OSH
A is an organization that approves all industrial safety components.

In the description of the present embodiment, only the two model embodiments are used. However, when the present invention is considered again, for example, a metal roof cover panel is made of plastic, wood, or other material. Can be replaced with a panel. For this reason, the claims refer to the panels as all-weather only. Further, a heat insulating material other than glass fiber may be used. The member described above as a haze may be a timber beam or a member having a truss structure such as “DeltaJoist” of Butler Manufacturing. The term "haze" in the following claims is intended to protect against any variations.

Another variant of the invention relates to a metal plate supported by a haze in which a mesh-like member has been placed beforehand. The dressing is covered by a rigid insulation board, which is then top covered with felt and bitumen coated waterproofing. As described above, according to the structure of the mesh-like roof surface shown in each of the above embodiments, the worker falls down from the roof under construction, or the tools or structures fall on the worker under the roof. It is possible to realize a structure of a mesh-like roof surface with excellent safety for preventing occurrence of an accident.

The present invention can be applied to a modification or a modification of each of the above embodiments without departing from the spirit thereof.
