Description

  The present invention relates to a frame having a joint structure not based on welding. It is related with the flame | frame used for the opening panel which attached the opening part apparatus especially.

  An opening device such as a window of a building such as a house is attached to a steel frame which is a main structural element of the building by an opening panel 700 which is a steel frame 710 provided with an opening device 780, as shown in FIG. There is building technology.

  Thus, by attaching an opening part apparatus to a building with an opening panel, the said opening panel can be combined with an outer wall material and the wind-resistant performance of a building can be improved. Furthermore, the opening panel can be produced in advance at another place in advance, and only the opening panel can be provided at the construction place, so that the work efficiency can be improved.

  Until now, in the steel frame of the opening panel, the joining of the frame members constituting the steel frame has been progressed from non-welding to non-welding from the previous welding. This is because the welded portion requires rust prevention treatment, has quality problems, distortion and bending due to heat, and training of excellent welding engineers. Therefore, conventionally, the frame material of the steel frame is in a state where a part joined by welding and a part joined by a method other than welding are mixed. Although there is no particular document disclosed about this, it is a matter performed by those skilled in the art.

  However, although the non-welding of the steel frame has been promoted, there is still a part that cannot be effectively joined unless it is welded. For example, as shown in FIG. 8 in which the joining portion is enlarged, the end surface of one frame member 840 is linear, and the end surface is joined so as to abut against the side surface of the other frame member 820. Is mentioned. In this case, since the line and the surface are joined, effective joining is difficult unless welding is used. Also, in order to solve this problem, if any method is used to create a surface at the edge of the frame material and join it, the opening panel will have strength that takes into account the load that supports the opening device and outer wall. There was also a problem that it was difficult. Moreover, there existed a problem that a junction shape etc. could not be changed greatly from the relationship of the accommodation of the opening panel in a construction site, and a steel frame or a hardware. In addition, production facilities and tools that can be applied to the shape of the joint portion are thereby limited, and joining other than welding is difficult.

  Therefore, the present invention maintains the strength as a structure by joining the end of one frame member and the side surface of another frame member by a method that does not involve welding without greatly changing the shape of the conventional joint portion. It is an object to provide a frame that can be used.

  As a result of intensive studies, the inventor has developed a frame capable of maintaining the strength with a structure that joins the joining portions of the frame without welding. The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

The part shown by A in FIG. 1 is a joint portion between the vertical frame 120 which is a joint frame material and the horizontal frame 140 which is a joint frame material. The said site | part is expanded and shown in FIG. In FIG. 2, the upper left side of the vertical frame 120 and the horizontal frame 140 indicates the outdoor side, and the lower right side of the paper indicates the indoor side. 2 shows a cross section of the vertical frame 120 in a portion indicated by B, and shows a cross section of the horizontal frame 140 in a portion indicated by C. As described above, the vertical frame 120 is a substantially L-shaped member, and the horizontal frame 140 is a U-shape having an opening on the lower side, and has a cross section in which one side of the indoor side extends. The vertical frame 120 and the cross member 140 are joined at a portion indicated by D in FIG. Here, the end of the horizontal frame 140 is in contact with and joined to one surface of the vertical frame 120 facing the horizontal frame 140.

  3 is a perspective view showing the vertical frame 120 and the horizontal frame 140 in an exploded manner in order to explain the structure of the joint portion. The vertical frame 120 has a slit 121 at a lower portion of a portion 120 a on the side facing the horizontal frame 140 of the vertical frame 120. The width of the slit 121 is set to be slightly larger than the thickness of the horizontal frame 140. The height of the slit 121 is substantially the same as the height in the vertical direction of the second mounting portion 143 described later. Further, a notch 122 is provided at the indoor side end portion below the portion 120a. The notch 122 is cut out in the indoor / outdoor direction with the same size as the thickness of the horizontal frame 140 and in the vertical direction with the same height as the height in the vertical direction of a first mounting portion 142 described later.

  The horizontal frame 140 includes a base portion 141, a first attachment portion 142 disposed at an end portion of the base portion 141, and a second attachment portion 143. As described above, the base 141 is integrally formed with the vertical part 141a on the indoor side, the horizontal part 141b on the upper part, and the vertical part 141c on the outdoor side. The first mounting portion 142 extends from the upper end portion of the portion 141a in the outdoor direction. Therefore, the 1st attaching part 142 becomes the attitude | position arrange | positioned in the outdoor direction at right angles from the upper end part of the site | part 141a. The vertical size of the first mounting portion 142 is substantially the same as the vertical height of the portion 141c. The size in the indoor / outdoor direction is approximately 2/3 of the distance between the portion 141a and the portion 141c. Further, the distance between the first mounting portion 142 and the end portion of the base portion 141 is slightly larger than the thickness of the vertical frame 120. On the other hand, the 2nd attachment part 143 is extended in the room direction from the lower end part of the site | part 141c. Accordingly, the second mounting portion 143 is in a posture arranged in the room direction at a right angle from the lower end portion of the portion 141c. The size in the vertical direction of the second mounting portion 143 is substantially half of the height in the vertical direction of the portion 141c. The size in the indoor / outdoor direction is approximately 1/3 of the interval between the portion 141a and the portion 141c. The second mounting portion 143 is disposed on the same plane as the first mounting portion 142 in the indoor / outdoor direction. Therefore, the first mounting portion 142 and the second mounting portion 143 are configured to block part of the end opening of the base body 141.

  In addition, rivets 175 and 175 are provided at the joining portion.

  Next, returning to FIG. 2, the joining state of the vertical frame 120 and the horizontal frame 140 will be described. As described above, the vertical frame 120 and the horizontal frame 140 are joined at the portion indicated by D in FIG. As can be seen from FIG. 2, the first attachment portion 142 is disposed so as to hold the lower end portion of the vertical frame 120 from the indoor side. Therefore, the indoor side lower end portion of the vertical frame 120 is sandwiched between the end portion of the base portion 141 and the first mounting portion 142, and the indoor side lower end portion of the vertical frame 120 and the first mounting portion 142 are in contact with each other on the surface. Can do. Thereby, the parts which contact on the said surface are joined by the rivets 175 and 175, and the vertical frame 120 and the horizontal frame 140 are joined. At this time, since the first attachment portion 142 is arranged through the notch 122 of the vertical frame 120 shown in FIG. 3, the upper surface of the notch 122 and the upper surface of the first attachment portion 142 are in contact with each other. Therefore, the load from the vertical frame 120 can be received at the hooked portion. As a result, the load applied to the rivets 175 and 175 can be reduced, and durability and reliability can be improved.

  Furthermore, the second attachment portion 143 is disposed so as to hold the vertical frame 120 from the outdoor side through the slit 121 shown in FIG. Therefore, the vertical frame 120 is sandwiched between the end portion of the base 140 and the second attachment portion 143. At this time, since the second attachment portion 143 is passed through the slit 121, the upper surface of the slit 121 and the upper surface of the second attachment portion 143 are arranged in contact with each other. Therefore, the load from the vertical frame 120 can be received at the contacted portion. As a result, the load applied to the rivets 175 and 175 can be further reduced, and the durability and reliability can be improved. Furthermore, the positional relationship between the slit 121 and the second mounting portion 143 can facilitate the positioning of the vertical frame 120 and the horizontal frame 140 during joining.

  By joining using the 1st attachment part 142 and the 2nd attachment part 143 as mentioned above, a junction part can be joined with rivets 175 and 175, and it is made non-welding which was difficult until now Can do. In addition, the frame 110 can be made without greatly changing the shape of the conventional joint portion. Here, the joining of the vertical frame 120 and the first attachment portion 142 need not be limited to joining by rivets. For example, it is possible to join with bolts and nuts. Any joining method other than welding that can obtain sufficient strength by joining the surfaces can be applied.

  In addition, by using the first attachment portion 142 and the second attachment portion 143 to join the vertical frame 120 from two directions, the directions indicated by E and F in FIG. Sufficient bonding strength can be obtained even for the force on the cross member 140 from such a direction. In addition, since the lower portion of the vertical frame 120 is disposed between the end surface of the base 141 of the horizontal frame 140 and the first and second mounting portions 142 and 143, the vertical frame 120 and the horizontal frame 140 are connected to each other indoors. The vertical frame 120 acts on the first and second attachment portions 142 and 143 even when the force is separated in the direction orthogonal to the outer direction. Thereby, the load concerning the rivets 175 and 175 can be reduced, and sufficient strength and bonding reliability can be obtained.

  Furthermore, by placing the slit 121 and the second attachment portion 143 and the notch 122 and the first attachment portion 142 in contact with each other, the load from the vertical frame 120 or the like can be dispersed in the contacted portion. . As a result, it is possible to reduce the load applied to the rivets 175 and 175 and improve the durability and reliability of the frame 110, particularly at the joining portion.

  Here, although the joining about the site | part shown by A of FIG. 1 was demonstrated, especially in the other end side of the horizontal frame 140, etc., it can join similarly also in every other site | part.
