Abstract

The utility model relates to an improved screw connection free angle steel frame combining structure, which comprises upright rods and transverse rods which can be combined mutually. A plurality of buckle sheets are convexly arranged in an extending way at equal intervals on the inner sides of the rod bodies of the upright rods along the longitudinal axis direction, the buckle sheets are in a plurality of changing folded shapes, outward changing arc fastening parts are arranged on the top ends of the buckle sheets, fastening holes are arranged on the positions of the transverse rods corresponding to the buckle sheets of the upright rods in a carving way, the fastening holes are used for being penetrated through by the buckle sheets of the upright rods, positioning grooves are arranged concavely between the fastening holes on the inner sides of the transverse rods and on the suitable places of the upmost parts and the lowest parts of the transverse rods at equal intervals, and the positioning grooves are used for clamping and positioning the fastening parts which are penetrated through and striden in with the buckle sheets correspondingly. The utility model is a structure that can be tightened and positioned quickly, and the thing that the buckle sheets are abutted when a plurality of adjacent angle steel frames are assembled can not happen.

Description

Improvement exempt from the slotted-angle shelving composite construction that is spirally connected

The utility model relates to a kind of angle steel composite construction of exempting to be spirally connected, and refers to that especially a kind of upright, cross bar clip is combined in its side, not hinder several slotted-angle shelvings engineering construction of establishing of adjacent set simultaneously.

The composite construction of known slotted-angle shelving (or claiming combined bay) as the combining structure improvement of combined bay and the improvement structure of angle steel rack, is the vertical rod and the bar structure that can make up mutually, wherein:

Vertical rod is engraved in the suitable spacing of the y direction of cross bar and to be provided with several fastening holes, and between the adjacent fastening hole and the top and below locate respectively to have engraved locating slot, and the structurally improved locating slot of angle steel rack does not have and penetrated the body of rod, only establishes for the low-lying area.

Cross bar is provided with the cramp of curved arc shape extension down in the position of the corresponding fastening hole in the body of rod outside, and the lower edge of cramp outwards sticks up tool one guide card.

When implementing, vertical rod is positioned at side outside the cross bar, treats that the cramp of cross bar wears respectively, strides into the fastening hole of vertical rod, makes the guide card of cramp arrive locating slot and the packing location through the fastening hole place; This practises the formula combination function, though be quick and easy, but it is some disappearance and wait to improve still, wherein the most the sick place of dirt see shown in Figure 1, at the cramp 201 of cross bar 20 after making up with vertical rod 10, expose at the cramp 201 in the outside and must conflict mutually after its combination, so that closing fully, increase inconvenience in the operation on foot and increase the space, again when if wherein a cross bar 20 must taking-ups, the cramp 201 that often is subject to its outside cramp 201 and adjacency inconsistent and can't on carry, cause in the operation and very perplex.

The purpose of this utility model is to provide a kind of slotted-angle shelving composite construction that is spirally connected of exempting from of improvement, the structure of packing location fast, in addition because the cramp of vertical rod inboard wears to the fastening hole of cross bar, strides into and locatees, do not influence outside the vertical rod lateral surface fully and see, thereby, when number slotted-angle shelving adjacent set was established, no cramp supported the facts of pulling.

The purpose of this utility model is to realize like this, the position of fastening hole on vertical rod and the cross bar and cramp is exchanged, make vertical rod establish cramp, and cross bar is established fastening hole, in addition the cramp position of vertical rod must be within cross-bar body the side place, then the inside buckle of its combination back cramp, protrude from fastening hole, the side also is a flat outside its vertical rod, so, just do not hinder carrying out that several slotted-angle shelving adjacent set establish, and do not have clip and be easy to take out arbitrary cross bar because of lateral surface.

Structure of the present utility model mainly comprises the vertical rod and the cross bar that can make up mutually; Vertical rod is at the y direction of body of rod inboard, and the equi-spaced apart extension is convexly equipped with the cramp that several tools are counted bending, and the cramp top end is the blocking part of tool one outside curved arc shape; Cross bar is engraved in corresponding vertical rod cramp position, the body of rod outside and is provided with fastening hole, cramp for vertical rod wears, strides into, in addition between inboard each fastening hole of cross bar and upper and lower appropriate location equidistantly be provided with locating slot, the blocking part that wears, strides into cramp for correspondence is received card, location.

The utility model has the advantages that one can chase after the structure of tightening position fast, with maximum different being of the formula of habit clip position upright, cross bar is gone to inboard place by the outside, overcome the situation that the visible cramp of the formula of habit outward appearance protrudes fastening hole, shape still can remain flat outside its vertical rod, and when array slotted-angle shelving group is established, the disappearance of conflicting mutually as both sides cramp as the habit formula also will can not take place in two adjacent vertical rods, cause the inconvenience and the flaw of engineering.

1-vertical rod, 11-cramp

111-blocking part, 2-cross bar

21-fastening piece, 22-locating slot

Embodiment:

See also shown in Fig. 2,3, the utility model improvement exempt from the slotted-angle shelving composite construction that is spirally connected, comprising: the vertical rod 1 that can make up mutually and cross bar 2, wherein:

Vertical rod 1, the y direction in body of rod inboard, the equi-spaced apart extension upwards is convexly equipped with several cramps 11, and cramp 11 is several bendings, and its top end is the blocking part 111 of tool one outside curved arc shape.

Cross bar 2, engrave in corresponding vertical rod 1 cramp 11 positions and to be provided with fastening hole 21, cramp 11 for vertical rod 1 wears, strides into, in addition be provided with locating slot 22 at cross bar 2 21 of inboard each fastening holes and the equidistant low-lying area of upper and lower appropriate location thereof, the blocking part 111 that wears, strides into cramp 11 for correspondence chases after tightly, locatees; Wherein locating slot 22 also can be through hole, is not also establishing locating slot 22 below the fastening hole 21 above the top fastening hole 21 or, and the utility model serves as to implement illustration with the locating slot 22 that wears in graphic.
