Description

  The present invention relates to the production of steel doors such as hinged doors and sliding doors. More specifically, the present invention is composed of front and rear surface plates made by bending a metal plate and a door core material. This invention relates to a metal door with a small face screw assembled type of a steel door attached to the door.

  For example, as a steel door for buildings, panels made of metal plates are joined to both the front and rear surfaces of a metal core that is vertically and horizontally braided. Metal doors are widely known. The set of metal doors described above can be assembled relatively easily by welding. However, it takes time to finish the sanding process, putty processing, etc. Have problems such as outbreaks.

Therefore, in order to increase rigidity with light weight with respect to the door, a flash door is proposed in which a metal reinforcing material is combined with a wooden core on both left and right edges.
The metal reinforcing material is, for example, formed in a cross-sectional groove shape and fitted inside a wooden core material, and a horizontal core material, a crosspiece, or the like is joined to the metal reinforcing material ( See Patent Documents 1 and 2 below).

  However, in the case of this flush door, the combination of a wooden core material and a metal reinforcing material increases the number of parts, which leads to increased costs, takes time for assembly, and makes it difficult to separate the two at the time of disposal. There was a problem that there was. Further, in the case of a conventional flash door, since a single panel is attached to each of the front and rear surfaces of the core material, the surface form of the door is uniform and there is a tendency that the design is lacking.

In order to provide a door with a small number of parts, high rigidity against warping and twisting, and easy separation by dissimilar materials during assembly work or disposal, the door is made up of two panels made of wood board A left and right pair of vertical frames made of a metal shape or a resin shape and holding the front and rear panels, and the left frame includes a core portion interposed between the left edges of the inner surfaces of the front and rear panels; And two panel receiving portions each having a groove shape that is provided on both the front and rear sides of the front and rear panels and into which the left edge portions of the front and rear panels are respectively fitted. The right frame is interposed between the right edge portions of the inner surfaces of the front and rear panels. There has been proposed a core portion and two panel receiving portions that are provided on both the front and rear sides of the core portion and into which the right edge of the front and rear panel is respectively fitted (Patent Literature). 3).

In order to improve the deflection rigidity of the wall plate and door plate against the load in the vertical direction of the wall surface, a reinforcing member is joined to the wall surface at a straight line connecting two diagonal lines of the wall surface and door surface, and a central member is provided at the intersection In addition, it has been proposed to improve the deflection rigidity of the wall surface by joining the central member to both the reinforcing member and the wall surface of the straight portion (see Patent Document 4).

In assembling the door frame, it is possible to provide a door frame that enables the use of a metal plate whose surface has been pre-decorated as well as cost reduction without performing welding work. The door frame is composed of one lower frame, the both ends of the upper frame are coupled to the upper ends of the left and right vertical frames, and the both ends of the lower frame are coupled to the lower ends of the left and right vertical frames. In the door frame in which the door is accommodated in the door frame, a locking tongue piece is formed on any one end surface portion in each coupling portion, and the other side surface portion in each coupling portion Alternatively, a locking hole is formed in the upper surface, and this locking tongue piece is fitted into the locking hole and bent, and a fixing screw as a fixing member is inserted from the mounting hole side, and further fixed by screwing into the mounting hole. A door frame is proposed (see Patent Document 5).

It is a joining method in which a groove is formed on the side of a bar-shaped metal building material, and the building material with a claw is fitted and welded. A construction method that eliminates the process of polishing dirt from welding on the assumption that it is covered with a decorative plate is proposed. (See Patent Document 6).

Conventionally, joining of metal building materials is often performed by welding, and in that case, the welding beat remains as it is, but when it becomes a joinery, it is not possible to finish paint with the weld bead portion as it is. For this reason, the welded part is finished with a sander or the like until it has the same unevenness as the unwelded part, and it takes a lot of time to finish, which is the biggest bottleneck in shortening the time to complete the door. Therefore, there is a demand for a fast fixing method that has the same rigidity as the welding assembly and changes to welding.

Adopting a method to fix the front and rear surface plate butt joints with screws, and this method does not join the two front and rear surface plates, so it is necessary to increase the rigidity of the door Become. By changing the arrangement and joining position of the core material of the door, the core material suitable for the hanging bracket used is assembled to increase the rigidity.

Japanese Patent Laid-Open No. 5-1492 JP-A-9-203278 JP 2007-186892 A JP 2003-176088 A JP 2002-174083 A JP 11-239873 A

  In general, the door is assembled by using a predetermined number of strength bones and central bones on one surface plate and a structural adhesive tape at a predetermined position. In many cases, the other face plate is covered and the small edge butt portion of the face plate is welded. However, this method requires a sander finish over the entire length of the assembled door, and also requires putty treatment before the rust-prevention coating process, leaving the problem that the door assembly time cannot be shortened. . Specifically, on the small edge of the door, it is necessary to polish to flatten the deformation of the surface shape, such as deviation of the butt part due to bending error, bead convex part due to welding joint, and plating layer depending on polishing There is also a problem that the shaving off of the steel deteriorates the weather resistance.

The present invention is a door manufactured by assembling two face plates and a core material, and the assembly work is performed by using a screw member to join the three or four door facets. The purpose is to maintain the rust prevention performance of the steel plate. Because there is a concern about the reduction in the rigidity of the door due to the fact that the surface plate is not integrated, the position of the center of the door and the fixing method of the abutting part should be considered in consideration of the position of the center of gravity of the door and the hanging bracket used. New challenges will emerge. The object is to provide a door that simplifies the work process, maintains rigidity against warping and twisting, and facilitates separation work for different materials during assembly work and disposal. Another object is to easily assemble a set of doors such as a door that can be diversified in surface form and has excellent design.

  Made of a metal plate consisting of two front and rear plate members bent into an L shape at the four sides of the metal plate, a metal frame core material bent into a U shape to form a door, a rivet or screw member, and a structural adhesive tape In the door, the metal door has a thickness of 40 to 100 mm, a width of 600 to 1500 mm, a length of 1800 to 3000 mm, and the two surface plate members have a width of 7 to 50 mm at the upper and lower and left and right ends of the door. It is a panel plate material that is bent in four directions into a letter shape, and the door core is made of a predetermined number of metal frames bent into a U-shape with a plate thickness of 1.6 to 3.2 mm, a width of 36 to 96 mm, and a height of 15 to 30 mm. This is a door-end-face screw-assembled metal door that is constructed by placing it at a predetermined position, butting it with a rivet or screw member and a structural adhesive tape, butting the face plate of the face plate bent in four directions. That.

The panel plate used for the metal surface plate is a surface-treated steel plate with a thickness of 1.2 to 1.6 mm. In order to obtain accurate diagonal dimensions, the plate material is cut on four sides and the cutting blade side is the outer surface. L-shaped bending is performed, and the surface plate dimensions after processing are 600 to 1000 mm in width and 1800 to 2350 mm in length,
A metal frame core material that gives rigidity to the door is sandwiched from both sides, the L-shaped bending tip is abutted, and the back surface of the surface plate and the core material are bonded with a structural adhesive tape. Adhere with and join.

In joining the small edge butt portion of the metal surface plate, the blade side of the cut surface is brought out to the surface side, the cut surface is made into a uniform thread surface state, and the error in the L-shaped bending process is eliminated. Prior to correcting the misalignment of the two faceplate butt face by using a double roller, they are fixed by rivets or screw members.

The metal frame core material that gives the metal door rigidity has a metal frame bent into a U-shape with a plate thickness of 1.6 to 3.2 mm, a width of 36 to 96 mm, and a height of 15 to 30 mm. The butt portion is bonded and fixed after being arranged as a force bone located at the edge of the surface plate periphery of the door, and the central bone located in the center portion of the surface plate has an interval width of 150 to 250 mm and is equally spaced In the case of a large door having a width of 950 to 1500 mm and a length of 2100 to 3000 mm, a round steel rib is inserted to assist the rigidity of the door.

  The metal fittings used for the metal doors are hinges or hibot hinges, and in accordance with the change of the suspension fulcrum, considering the transition of stress concentration parts of the core material that supports the weight of the door, The joint leg length of the butting part is changed with the hinge or hibot hinge suspension. Specifically, in the case of hinge suspension, the joint leg length of the four corners of the door and the butting part is extended, and in the case of the pivot hinge suspension, the lower part The joint leg length of the buttocks of the ribs and middle bones is extended, and the L-shaped bent portion of the lower surface plate of the door is fixed to the lower ribs with rivets or screw members.

The present invention can simplify the door assembly process and the painting process by using screw assembly as the method of joining the two face plates constituting the door and the facet of the core material. Cost reduction can be realized and the rust prevention performance of the plated steel sheet can be maintained. Specifically, the simplification of the sanding process of the small face of the door of steel fittings has been said as an eternal issue in this industry. It has become possible to provide a door that allows the use of a metal plate whose surface is previously decorated. In addition, it is a door that simplifies the work process, maintains rigidity against warping and twisting, and is easy to separate by dissimilar materials during assembly work and disposal, and can be diversified in surface form. We were able to provide an excellent door.
