Description

  The present invention relates to a rack cover that is attached to a bent connection portion of two linear racks bent and connected at an arbitrary angle in a horizontal plane.

For example, as shown in FIG. 10, a linear rack 1 for wiring and piping a long object such as a cable, a pipe, and a refrigerant pipe to the inside of a building or the like, or on the roof, outdoors, etc. .. Are connected to each other by a plurality of constant digits 3, 3,...
The linear rack 1 is installed with its ends connected to each other in the longitudinal direction with joints, and long objects such as cables, pipes, refrigerant pipes, etc. on the child beams 3, 3,. Wiring and piping (not shown).

  In order to prevent dust from entering the linear rack 1 and especially when the linear rack 1 is installed on a rooftop or outdoors, a linear roof shape as shown in FIG. A rack cover 10 is placed on the upper surface of the linear rack 1 and fixed with cover stoppers 11 and bolts 12 locked to the lower edge of the main beam 2.

By the way, the connection direction of the two linear racks 1 and 1 is not limited to the linear direction, and it is necessary to bend and connect the horizontal plane at an angle suitable for the situation of the construction site due to the presence of an obstacle.
When the two linear racks 1 and 1 are bent and connected at an angle in the horizontal plane as described above, a horizontal bend rack (not shown) having a structure in which two parent beams curved in an arc shape are connected by a plurality of child beams. The straight racks 1 and 1 are connected to both ends of the horizontal bend rack by straight joints.

The linear roof rack cover 10 shown in FIG. 10 is attached to the upper surface of the linear racks 1 and 1, and the horizontal bend roof cover (see FIG. 10) is curved on the upper surface of the horizontal bend rack in the same manner as the horizontal bend rack. (Not shown).
There are three types of horizontal bend racks and horizontal bend roof-shaped covers for 30 °, 45 °, and 60 °.

  However, in the construction site, it is often necessary to set the connection angle to an angle other than 30 °, 45 °, and 60 °. For such a case, the horizontal universal joint 20 (which can be an arbitrary connection angle) 11), two linear racks 1 and 1 are connected at a desired angle as shown in FIG.

  That is, as shown in FIG. 11, the horizontal universal joint 20 is formed by connecting two attachment plates 21, 21 to be attached to a longitudinal end portion of a main beam of a linear rack by a hinge 22. Then, as shown in FIG. 12, the mounting plate 21 is fixed to the end of each of the main girders 2 of the two linear racks 1 and 1 with bolts 23 and nuts 24, and is bent and connected at a desired angle.

  However, when two linear racks 1 and 1 are connected at an arbitrary angle according to the situation of the construction site in this way, the horizontal bend roof rack cover described above is for 30 °, 45 °, and 60 °. There are only three types, so that the two pieces 10a and 10b are made into two parts by cutting the linear roof rack cover 10 shown in FIG. 10 according to the connection angle as shown in FIG. As shown in FIG. 13, the surfaces 11a and 11b are attached to the upper surface of the bent connection portion of the two linear racks 1 and 1, respectively.

However, with this conventional method,
(A) Since the linear roof rack cover 10 must be cut in accordance with the connection angle of the linear racks 1 and 1 at the construction site, it is very complicated and time-consuming.

  (B) In addition, it is very difficult to make two cut products 10a and 10b obtained by cutting the linear roof rack cover 10 at an accurate angle, and there is a gap between the two cut surfaces 11a and 11b. Frequent need to redo cutting.

  (C) Further, it is very difficult to cut the straight roof rack cover 10 whose center swells in a triangle in a straight line, and it is usually uneven, and a gap is left at the joint. Therefore, the work of leveling the cut surfaces 11a and 11b straight is necessary, which is very complicated and takes time.

  (D) In order to shorten the delivery time, the connection angle between the two linear racks 1 and 1 is calculated in the design stage, the linear roof rack cover 10 is cut, and the cut products 10a and 10b are welded. Even if the cover is manufactured in advance, the connection angle often deviates slightly in the connection work between the two linear racks 1 and 1 at the construction site. However, it often occurred that it could not be used.

  The present invention solves such a problem, without cutting the linear roof-shaped rack cover according to the connection angle, without filing the cut surface, and without producing it in advance. An object of the present invention is to provide a rack cover for a bent connection part that can be adapted to any connection angle at a construction site.
