Abstract
Disclosed is a seaming corrugated steel pipe which relates to corrugated steel pipes and resolves the problems of large welding workload and requirement of antiseptic treatment of welded seams of conventional corrugated steel pipes. The seaming corrugated steel pipe is formed by rolling a corrugated steel plate (1), wherein a first folded edge (1-1) of the corrugated steel plate (1) is bent downwards to form a hook shape, a second folded edge (1-2) of the corrugated steel plate (1) is bent upwards to form a hook shape, and the first folded edge (1-1) and the second folded edge (1-2) are mutually tightly pressed in a snap-fit manner. The seaming corrugated steel pipe omits antiseptic treatment of the welded seams by adopting snap-fit technique without welding needs, a snap-fit position formed by four steel plate layers instead of original one steel plate layer increases rigidity and strength of the corrugated steel pipe, and additionally the corrugated steel pipe has the advantages of convenient processing, work efficiency improvement and lowered cost.
Description
Technical field
The utility model relates to a kind of corrugated steel tube.
Background technique
Existing corrugated steel tube is to be pressed by a plurality of Corrugated Steels to justify into pipe, is welded into the corrugated steel tube of Len req.The welding job amount of corrugated steel tube is big, and weld bond is arranged, and corrugated steel tube is had burn part, and anticorrosion zinc-plated destroyed around the corrugated steel tube weld seam is so also need the coating anti-corrosion material to guarantee antiseptic property.
The model utility content
The purpose of this utility model is need carry out antiseptic problem in order to solve the big and weld seam of existing corrugated steel tube welding job amount, and then a kind of seaming corrugated steel tube is provided.
The technical solution of the utility model is: the seaming corrugated steel tube is rolled into by Corrugated Steel, and first flanging of Corrugated Steel is bent into downwards and colludes shape, and second flanging of Corrugated Steel upwards is bent into and colludes shape, and first flanging and the mutual interlock of second flanging compress.
The utility model compared with prior art has following beneficial effect: the utility model adopts seaming technology, need not welding, thereby has also eliminated the preservative treatment of weld seam; Seaming of the present utility model place becomes four layers of steel plate by original one deck steel plate, thereby has increased the rigidity and the intensity of corrugated steel tube; In addition, corrugated steel tube of the present utility model is convenient to processing, thereby has improved working efficiency, has reduced cost.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model, and Fig. 2 is that partial enlarged drawing is looked on the right side of Fig. 1.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1～Fig. 2, the seaming corrugated steel tube of present embodiment is rolled into by Corrugated Steel 1, the first flanging 1-1 of Corrugated Steel 1 is bent into downwards and colludes shape, the second flanging 1-2 of Corrugated Steel 1 upwards is bent into and colludes shape, and the first flanging 1-1 and the mutual interlock of the second flanging 1-2 compress.
Embodiment two: in conjunction with Fig. 2 present embodiment is described, the thickness of the Corrugated Steel 1 of present embodiment is 1mm～3mm.So be provided with, be convenient to moulding.Other composition is identical with embodiment one with annexation.
Claims (2)
1. seaming corrugated steel tube, it is rolled into by Corrugated Steel (1), it is characterized in that: first flanging (1-1) of Corrugated Steel (1) is bent into downwards and colludes shape, second flanging (1-2) of Corrugated Steel (1) upwards is bent into and colludes shape, and first flanging (1-1) compresses with the mutual interlock of second flanging (1-2).
2. according to the described seaming corrugated steel tube of claim 1, it is characterized in that: the thickness of described Corrugated Steel (1) is 1mm～3mm.
