  The present invention will be described in more detail below with reference to the example of the drawings. A is, for example, an aluminum screen designed to decorate a gate frame by being attached to a part of a gate frame or a sleeve portion. The screen A has one end fixed to the horizontal member 11 supported by the support column 1 and the other end fixed to the wall surface so that the upper horizontal frame member 2 is arranged in a erected shape and a large number of the horizontal frame member 2 is attached to the horizontal frame member 2. The grid bar 3 is cross-fixed. At this time, the grid bar 3 is formed as a long cylindrical pipe. The grid bar 3 of the cylindrical pipe is smaller in diameter than the grid bar 3 and has a screw through hole in the hollow portion. 41, a short cylindrical mounting bracket 4 and a wall thickness corresponding to the difference between the inner diameter of the cylindrical pipe and the outer diameter of the cylindrical mounting bracket 4, or the inner circumference of the cylindrical rail 3 of the cylindrical pipe or the cylindrical mounting bracket 4 By providing the elastic member 5 arranged on the outer periphery of the The cylindrical mounting bracket 4 is fixed to the horizontal frame member 2 for mounting the lattice beam by screws 6 which pass through the screw through holes 41 and are screwed into the frame member 2, and the elastic member is attached to the cylindrical mounting bracket 4. The grid bar 3 is fitted through 5 and the elastic bar 5 is elastically held by the elastic member 5 so as to be cross-fixed to the horizontal frame member 2.

  In this example, the horizontal frame member 2 for attaching the lattice beam includes a frame base body 21 having a hollow base 22 and front and rear ridges 23 forming an opening groove on the bottom surface thereof, and the frame base body. 21 by a split-type aluminum extrusion material provided with a groove cover 25 snapped in or slidably engaged with the front and rear ridges 23 so as to close the opening groove 21, and by a screw 6 of the cylindrical mounting bracket 4. The cylindrical mounting bracket 4 is partially protruded from the groove cover 25 by screwing the screw 6 into the bottom surface of the hollow base portion 22 through the through hole 29 of the groove cover 25 to be fixed to the frame member 2. It is assumed that the cross-fixing of the grid bars 3 to the horizontal frame member 2 is performed on the groove cover 25.

  The horizontal frame member 2 of this example, in particular its frame member main body 21, is snapped to each lower end portion of a hollow base portion 22 having a rectangular cross section and a pair of parallel ridges 23 protruding in the same length from both front and rear ends thereof. One of the locking protrusions 24 of the in-locking is disposed, and using an aluminum extruded material provided with a thick portion for receiving a screw on the bottom plate of the hollow base 22, this is subjected to processing such as cutting, The frame body 21 has a hollow base portion 22 with a front-rear width of 7 to 8 cm, a height of several tens of centimeters, and a parallel pair of protrusions 23 with a width of several centimeters, for example, about 3 cm.

  The groove cover 25 that closes the opening groove of the frame body 21 of the horizontal frame member 2 includes a cover base portion 26 having substantially the same width as the front and rear width of the hollow base portion 22, and a snap-in lock on the front and rear ends thereof. The aluminum extruded material in which the grooves 28 are arranged is used, and the same is cut and processed. At this time, the locking grooves 28 are formed by the leg 27 protruding from the front and rear ends of the cover base 26. This is formed by recessing in the intermediate direction in the protruding direction toward the front and rear and outward. At this time, the groove cover 25 is provided with the above-mentioned through holes 29 at the grid beam installation location in the middle in the front-rear direction of the cover base 26, particularly in the center, and the through holes 29 are formed on the outside of the cylindrical mounting bracket 4. Depending on the diameter, the diameter is approximately the same, for example, about 2 cm so that it can be inserted.

  The grid bar 3 of this example is a cylindrical pipe having a circular cross-section having an outer diameter of, for example, about 4 cm, which is obtained by processing an aluminum extruded material and cutting it. On the surface, an interval regulating ridge 31 that regulates the interval between the cylindrical pipe and the cylindrical mounting bracket 4 is arranged. In this example, the interval regulating ridge 31 connects the lattice beam 3 to the cylindrical mounting bracket 4. A pair of protrusions projecting toward the center of the grid bar 3 so that the tip contacts the outer periphery of the cylindrical mounting bracket 4 when being fitted to the outer periphery of the cylindrical mounting bracket 4, for example, has a protrusion width of about 1 cm.

  The cylindrical mounting bracket 4 of the present example was formed by arranging a plurality of screw through holes 41 in the hollow portion by using an aluminum extruded material or a synthetic resin extruded material, particularly an aluminum extruded material subjected to processing such as cutting. For example, the cylindrical pipe member has a circular cross section having an outer diameter of about 2 cm, which is 1/2 of the inner diameter of the lattice material 3 of the cylindrical pipe, and has a short dimension, for example, a length of about 6 cm. The two threaded through holes 41 are arranged so as to face each other at this position. At this time, the threaded through holes 41 in this example are provided with slits in a part of the circumference thereof, such as a tapping hole. However, the inner diameter is slightly larger than the screw diameter of the screw 6 so that the screw shaft of the screw 6 can be inserted.

  The elastic member 5 of this example is a synthetic rubber-based member. In this example, the elastic member 5 has a preferable form having a certain degree of elasticity and friction resistance, such as EPDM. In this example, the elastic member 5 has a thickness of about ½ of the difference between the inner diameter of the lattice beam 3 of the cylindrical pipe and the outer diameter of the cylindrical mounting bracket 4, for example, the lattice beam 3. It is assumed that the extruded material extruded by opening the width of the pair of spacing regulating protrusions 31 arranged on the inner peripheral surface of the inner surface and cutting it into a C-shaped cross section is cut.

  Cross-fixation of the lattice beam 3 using the cylindrical mounting bracket 4 and the elastic member 5 to the horizontal frame member 2 formed in this way is performed through the through hole 29 of the groove cover 25 of the horizontal frame member 2. The cylindrical mounting bracket 4 is partially protruded from the groove cover 25 by screwing a screw 6 into the bottom surface of the hollow base portion 22, and the cross fixing of the cylindrical pipe 3 to the horizontal frame member 2 is fixed to the groove cover 25.

From the outside, a cylindrical hole is provided in the through hole 29 at the grid bar position provided in the groove cover 25 that is snap-in-locked to the horizontal frame member 2 and closes the opening groove. The mounting bracket 4 is inserted into the opening groove of the frame body 21 and the tip thereof is brought into contact with the lower surface of the hollow base 22 so that the cylindrical mounting bracket 4 partially protrudes from the groove cover 25. The screw 6 is inserted into the two threaded through-holes 29 from the protruding portion side, and the screw 6 is disposed in the hollow base portion 22 in this example. By screwing into the bottom plate, the cylindrical mounting bracket 4 is fixed to the horizontal frame member 2 at two locations in the circumferential direction, and the protruding portion protruding from the groove cover 25 is received. The cylindrical mounting bracket 4 is fitted by the lattice bar 3 so as to be in contact with each other. Well, thereby crossing the fixed grid bars 3 in the transverse frame member 2, in the present embodiment can be orthogonal fixed.

  At this time, the elastic member 5 can be fixed in advance to the outer peripheral surface of the cylindrical mounting bracket 4 by, for example, bonding, but in this example, the opening of the elastic member 5 having the C-shaped cross section is used. In order to receive the above-mentioned spacing regulating protrusion 31 in the groove, it is integrated with the inner peripheral surface of the grid bar 3 by, for example, bonding and fixing in advance, and the grid bar 3 is fixed in a state where the elastic member 5 is fixed. And the cylindrical mounting bracket 4 are attached to each other. For this mounting, for example, the grid bar 3 is slightly inclined to the cylindrical mounting bracket 4 and the spacing regulating protrusion 31 is directed to the outer peripheral surface of the cylindrical mounting bracket 4. As described above, the lattice beam 3 is pressed onto the cylindrical mounting bracket 4 while being slightly compressed while the elastic member 5 is slightly compressed, so that the cross fixation of the lattice beam 3 to the horizontal frame member 2 can be performed easily and reliably.

  In this way, the lattice beam 3 cross-fixed to the horizontal frame member 2 has a simple structure using the cylindrical mounting bracket 4 and the elastic member 5, and the end of the horizontal frame member 3 is exposed without the screws 6 being exposed to the outer peripheral surface thereof. 2, especially in contact with the groove cover 25 and integrated with the horizontal frame material 2 to provide a beautiful appearance with a good fit, and the lattice beam 3 is fixed to the frame having this type of frame material 2 Therefore, it can be set as a suitable structure.

  In the figure, reference numeral 7 denotes a lower horizontal frame member. In this example, the lower horizontal frame member 7 is formed by attaching the lattice beam 3 to the upper horizontal frame member 2 using the cylindrical mounting bracket 4 and the elastic member 5. After the cross-fixation, the same cylindrical mounting bracket 4 as described above is used, and this is fixed to the horizontal frame member 7 with the screws 6, and the cylindrical mounting bracket 4 is inserted into the lattice beam 3 and from the lattice beam 3. The screen A is assembled by disposing the screws 71 so as to be fixed. At this time, the horizontal frame member 7 is embedded in the ground together with the lower portion of the lattice beam 3.

  Although the illustrated example is as described above, the circular pipe is used as a support, the frame material is a vertical frame material, the circular pipe is cross-fixed to this, and the horizontal frame material or the vertical frame material is a single frame material. The frame material is made of an integral extruded material, the circular pipe and the circular mounting bracket are inclined at the tip of the circular pipe, the circular pipe is fixed to the horizontal frame material at an inclination, The circular pipe is cross-fixed to the frame material, and the frame material that closes the other end of the circular pipe is arranged in accordance with the usual method, or the other end is embedded in the ground or on the wall surface to Perform additional cross-fixation, make the cylindrical mounting bracket processed by cutting synthetic resin extruded material, make the elastic member made of foamed synthetic resin, Including the case where it is placed on the outer peripheral surface of the cylindrical mounting bracket.
