Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of joining frame members constituting a flash panel structure and an improvement of the frame members used for the method.

[0002]

2. Description of the Related Art A flash panel structure used for doors, partition panels, side panels of furniture, and the like is made up of front and back surfaces of frame members such as frames, frame edges or crosspieces. The skeleton member is generally made of wood. To join the wooden skeleton members, either a T-shaped joint, an L-shaped joint, or a parallel joint can be used. A method of joining in a form is adopted. Since the driven staples sink into the surface of the skeleton member, the surface board of the flash panel structure does not become inconsistent.

However, in order to provide rigidity against warping and twisting, when steel frame members are used for the inner core material of the vertical frame of the flush door, for example, the steel frame members are connected to each other or the steel frame members are used. And the wooden frame members cannot be joined by a tenon type, and when a staple or the like is driven in, as shown in FIG. 9, the wooden frame members D are made of steel but have the staples B as described above. The staple B floats on the surface of the material A, and the surface board C is raised. An L-shaped bracket may be attached to the side surfaces of the steel frame member and the wooden frame member to be joined so as to join the two, but not only the number of parts increases, but also the assembling of the door becomes complicated.

It is an object of the present invention to simply and economically produce a flat portion on a surface board when joining frame members of metal square pipes of a flash panel structure or a frame member of the same to a wooden frame member. It is intended to provide a joining method capable of joining both frame members and a frame member used for the joining method.

[0005]

According to the present invention, in order to achieve the above object, a frame member of a flash panel structure is formed by a metal square pipe having shoulders extending in the longitudinal direction at both shoulders in the width direction. To do. This metal square pipe is positioned so that the surface provided with the stepped portion comes to the front and back of the flash panel structure. Then, after the end portion of the other frame member is abutted in a T-shape with the side face in the thickness direction of one frame member of the two frame members to be joined in a T-shape, the abutting side face of the one frame member is the above step. The steel members are joined by striking the fixing members so as to straddle each of the other frame members to the left and right steps of the other frame member end.

Further, according to the present invention, in the case of joining in an L shape, the end portion of the other framing material to be joined is formed into an L shape on one end face of the framing material of the metal square pipe. Butting is performed by striking a fixing member so as to straddle both widthwise step portions of the one frame member to the step portions of the other frame member ends to join the two frame members.

Further, according to the present invention, by arranging the frame members of the above-mentioned metal square pipe so that the side surfaces thereof are almost in contact with each other, and driving them so that the side surfaces straddle the fixing member on the stepped portions of both sides, both steels are joined. Join the frame members in parallel.

In the present invention, the metal frame members are L-shaped.
Butt in a letter or T shape, attach a wooden receiving piece to the corner of this butt joint, and striking the wooden receiving piece from the step of each of the above-mentioned skeleton members. It is designed to join the frame materials.

Further, in the present invention, the frame member of the metal square pipe and the wooden frame member are driven so as to straddle the fixing member from the step portion of the frame member of the metal square pipe to a desired position of the wooden frame member. The two frame members are joined together.

[0010]

According to the present invention, since the fixing member is driven into the step of the metal square pipe, the fixing member does not cause swelling when the surface board is attached. Also, T-shaped,
Each of the L-shaped and parallel connections can be easily and easily performed by driving the fixing member.

Since the frame member is not a single square pipe but has step portions formed on both sides in the width direction along the longitudinal direction, even if a fixing member is driven into this step portion, each pipe does not sag.

Further, according to the present invention, when the surface boards are attached to each other, the inside of the structure is partitioned by the frame members, but at the T-shaped or L-shaped joint portion, the stepped portion of the metal frame member is formed in the in-plane adjacent space. The flow path of the air flow is formed by.

[0013]

The present invention will be described below in detail with reference to the illustrated embodiments. FIG. 1 is a view showing a frame structure of a flash door to which the present invention is applied. In the figure, reference numerals 1 and 1 are left and right vertical frames,
Each of these vertical rods 1 and 1 is made of a wooden outer vertical rod 2 and an inner vertical rod 3 having a required distance from the outer vertical rod 2.
With. The inner vertical frame member 3 is preferably made of a thin-walled steel square pipe, and step portions 3a, 3a are formed along the longitudinal direction on both shoulders in the width direction of the front and rear surfaces, as will be seen in detail from FIG. ing. Then, these inward vertical rods 3 are assembled such that the front and rear surfaces are located on the front and rear surfaces of the door.

Reference numeral 4 denotes an upper rail, and 5 denotes a lower rail, both of which are steel square pipes having the same structure as the above-mentioned inner vertical rod 3 and having step portions 4a, 4 thereof.
a and 5a, 5a are located on the front and rear surfaces of the door, and are joined to the left and right inner vertical rail members 3, 3 in a T-shape. 6 and 6 are upper and lower wooden horizontal frames.

The inner vertical frame member 3 and the upper rail 4 are joined together as specifically shown in FIG. That is, the end portion of the upper rail 4 is abutted against the inner side surface 3b of the inner rail member 3 at a predetermined position, and the inner side surface of the inner rail member 3 is moved from the step portion 3a of the waving to the joining end portion of the upper rail 4. The staples 7, 7 are driven so as to straddle the side step portions 4a, 4a, respectively. The driving of the staples 7 is performed on both the front and rear surfaces of the inner frame member 3 and the upper rail 4. The surface of the driven staple 7 is exposed to the surface of both frame members 3 and 4 made of square steel pipes, and this portion is absorbed by the step between the stepped portions 3a and 4a (see FIG. 3). Therefore, the supporting surfaces 3 before and after these frame members 3 and 4
Even if the front surface board 8 is attached to the c and 4c, the front surface board 8 is not raised by the staples 7.

The other joint end of the upper rail 4 and the left and right joint ends of the lower rail 5 are also stapled in the same manner.

FIG. 4 shows a case where the frame members 11 and 12 made of steel square pipes having the above structure are joined in an L shape. In this case, the joint end of one of the frame members 11 should be L so that the joint end of the other frame member 12 is substantially orthogonal to one side surface of the joint end.
The skeletons 17 are butt-shaped, and the staples 17 are driven from the step portions 11a, 11a on both sides in the front-rear surface width direction of the one skeleton member 11 to the step portions 12a of the other skeleton member 12 having the abutting side surfaces thereof to form a double skeleton member. 11 and 12 are joined. If the end faces of both frame members 21 and 22 are cut diagonally, the staple 27 is driven so as to straddle the outer step portion and the inner step portion, so that FIG.
The L-shaped joining seen in is possible.

FIG. 6 shows a step 31 of the frame members 31, 32 at the corners of the two frame members 31, 32 when the L-shaped joint is performed.
A receiving piece 39 having a thickness substantially equal to the thickness between a and 32a is attached, and staples 37 are driven from the step portions 31a and 32a of the frame members 31 and 32 to the front and back surfaces of the receiving piece 39, respectively. Can be done more reliably. The idea of interposing the receiving piece 39 can be similarly applied to the above-described T-shaped joining.

FIG. 7 shows an example in which a plurality of frame members 41 and 42 made of steel square pipes having the above structure are joined in parallel. In this case, the side surface to be joined is the stepped portion 41a,
Similarly, the staple 47 is driven so as to straddle 42a to join the two frame members 41 and 42 together. Staple 47
How to strike is orthogonal to the length direction of the frame members 41, 42,
Alternatively, it may be slanted.

In the T-shaped joint joined by using the metal square pipe with the stepped portion as described above, the T-shaped joint formed by the conventional method is used as a space portion in which the inside of the door is closed in the surface direction. While partitioning and blocking the flow of air flow, as shown in FIG. 8, the stepped portion surrounds the space in the center of the door with the upper and lower crosspieces 4, 15 and the inner vertical frame member 3 and the horizontal frame 5. It will communicate with the open space, improving the ventilation performance inside the door.

The frame member made of the square steel pipe having the above structure can be directly joined to the wooden frame member. For example, in the door of FIG. 1, the upper and lower ends of the inner vertical frame member 3 are joined to the wooden horizontal frames 6 and 6 in a T-shape. Therefore, when the staples are driven into the front and back surfaces of the wooden horizontal frame 6 from the stepped portions on both sides of the joint end of the inward vertical rod 3 of the steel square pipe, the staples fit into the steps on the steel square pipe side and Since the skeleton side bites into the wood, it does not project from the surface board supporting surfaces of both skeletons 6 and 3.

In the case of joining the above-mentioned framed member with the stepped portion to the wooden framed member in an L-shape, or in the case of connecting both in parallel, the same procedure as in the above-mentioned embodiment may be performed.

In these embodiments, various joints of the frame members of the door were mainly described, but the present invention is not limited to this, and can be directly applied to the joint of the frame members in other flash panel structures. is there.

Further, the frame member made of a metal square pipe may be made of not only steel but also other metal material such as aluminum.

Further, as a fixing member for joining the frame members together, a tacker, a stapler, or the like may be used as long as it has a length necessary for joining across the step portions of the frame member other than staples. It is also possible to use the above member.

[0026]

As described above, according to the present invention, the skeleton member is formed by a metal square pipe member having step portions extending in the longitudinal direction at both shoulders in the width direction. It is possible to join a frame member of this kind easily and economically without causing a fixed portion to be formed on the surface board by the fixing member that is joined by striking the fixing member between the step portions.

Further, according to the present invention, since the fixing member is driven into the stepped portion of the metal square pipe material, the settling does not occur as compared with the case where a single square pipe is used.

Further, according to the present invention, since a flow path of air passing through the step of the metal square pipe is formed in the T-shaped joint, the ventilation performance in the flash panel structure can be improved, The structure can last longer.
