Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a structure of a vertical frame portion in a prefabricated shelf constituted by a metal vertical frame and a metal shelf plate.

<< Prior Art >> A metal shelf formed by attaching a metal shelf plate to a metal vertical frame so that the supporting height can be adjusted is well known.

In this conventional device, a large number of engaging holes are punched or punched through a support member such as an angle member so as to be transparent at a constant pitch.

<Problems to be Solved> However, in the conventional metal shelf, since the side plate portion is punched or punched to form the engaging portion of the shelf plate, there is a problem that the strength of the column is deteriorated.

The present invention has been made paying attention to such a point, and an object thereof is to provide a column having a simple structure and high supporting strength.

<< Means for Solving the Problem >> In order to achieve the above object, the present invention comprises a pair of front and rear vertical frames and a plurality of connecting rods arranged between the vertical frames to form a gate frame. Vertical rib-shaped shelf board supports integrally projecting at regular intervals in the vertical direction on the opposite side surfaces of each strut, and by engraving a pair of upper and lower slits horizontally on some shelf board supports, It is characterized in that a shelf supporting body portion sandwiched by the both slits is formed with a connecting rod fitting projection, and the connecting rod formed by a square tube is press-fitted and fixed to the fitting projection.

<Operation> In the present invention, when forming a gate form frame with a pair of front and rear vertical frames and a plurality of connecting rods arranged between the vertical frames, vertical rib-shaped shelf boards are formed on the side surfaces of the columns facing each other. Supports are integrally projected at regular intervals in the vertical direction, and a pair of upper and lower slits are horizontally engraved on a part of the shelf support to connect the shelf support parts sandwiched by both slits. Since the fitting projection is formed and the connecting rod formed of a square tube is press-fitted and fixed to the fitting projection, it is not necessary to form a shelf plate that causes a decrease in strength on the column forming the vertical frame. , The upper and lower wall portions of the connecting rod that are mounted between both columns are fitted into the slits formed in the shelf support, and are firmly sandwiched between the upper and lower slits of the shelf support. Since the assembly strength of the metal shelf will increase, the load bearing strength of the metal shelf will be kept large. You can

<< Embodiment >> The drawings show an embodiment of the present invention. FIG. 1 is an exploded perspective view of a main part taken out, and FIG. 2 is a perspective view of an assembly shelf.

This assembly shelf (1) consists of a pair of vertical columns (2) arranged on the left and right.
(2) and a plurality of shelves (3) that are vertically bridged between this vertical frame (2) and (2), and a cross brace that is bridged between a pair of vertical columns (2) and (2) It is composed of (4) and.

Each gate type vertical frame (2) is a pair of front and rear aluminum alloy columns
(5) and an aluminum connecting rod (6) for connecting the front and rear columns (5, 5) are formed in a ladder shape. The strut (5) is composed of a strip material in which a rib (7) along the longitudinal direction is integrally erected on one side surface of the square pipe, and by cutting the rib (7) intermittently, it is made constant. The ribs (7) are left at intervals, and the remaining ribs (7) serve as a support for the shelf plate (3).
Then, two horizontal slits (8) are formed in the vertical middle portion of the ribs (7) at the appropriate positions of the uppermost position, the lowermost position and the middle of the remaining ribs (7), and the slits (8) are formed. ) Is formed on the fitting projection (9) of the connecting rod (6). Further, the connecting rod (6) is composed of a narrow square pipe, and the end face opening of the connecting rod (6) is press-fitted into the fitting protrusion (9) formed on the rib (7) of the column (5). By doing so, the vertical frame (2) is formed into a ladder-shaped frame body. The fitting protrusion (9) formed on the rib (7) is provided with a guide hole (10) for crimping, and after the connecting rod (6) is press-fitted into the fitting protrusion (9), the connecting rod ( By plastically deforming 6), in addition to press-fitting and fixing, fixing by crimping is performed to strengthen the structure of the vertical frame (2).

Further, the shelf plate (3) mounted between the left and right gate-shaped vertical frames (2) and (2) is arranged in the left-right direction between the pair of front and rear aluminum alloy side frame members (11) and front and rear side frame members (11). Crosspieces installed at appropriate intervals (1
With 2) and, it is constructed like a slat. This cross member (12) is made of a flat aluminum alloy square pipe,
The pair of front and rear side frame parts (11) is separated by press-fitting the square pipe crosspiece member (12) into the protrusions integrally projecting from the opposite side surface parts of the side frame member (11). It is installed improperly. Further, engaging hooks (13) that engage with the ribs (7) formed on the column (5) are formed at both left and right ends of the side frame member (11).

<Effect> In the present invention, in forming a gate form frame with a pair of front and rear vertical frames and a plurality of connecting rods arranged between the vertical frames, vertical rib-shaped shelf boards are provided on the side surfaces facing each other. Supports are integrally projected at regular intervals in the vertical direction, and a pair of upper and lower slits are horizontally engraved on a part of the shelf support to connect the shelf support parts sandwiched by both slits. Since the fitting projection is formed and the connecting rod formed of a square tube is press-fitted and fixed to the fitting projection, it is not necessary to form a shelf plate that causes a decrease in strength on the column forming the vertical frame. , The upper and lower wall portions of the connecting rod that are mounted between both columns are fitted into the slits formed in the shelf support, and are firmly sandwiched between the upper and lower slits of the shelf support. Since the assembly strength of the metal shelf will increase, the load bearing strength of the metal shelf will be kept large. You can
