Problems solved by technology
[0002] C-shaped steel is processed by hot coil and cold-bending. The bearing capacity is often selected too large, which increases the construction cost and causes corresponding waste, while the use of double-joint steel can effectively increase the bearing capacity
[0006] 1) Double welding increases the content of the process, the progress of manual welding is slow, and the supply exceeds the demand
Moreover, the gas and sparks generated during the welding process will cause serious harm to the human body and easily cause a fire;
[0007] 2) Double welding needs to be preset in the factory and shipped to the site

Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0025] Such as Figure 1-3 As shown, a kind of welding-free double steel, including the first steel 10 and the second steel 20, the first steel 10 and the second steel 20 back-to-back contact splicing (the first steel 10 and the second steel 20 are C-shaped steel, back-to-back setting), a number of round holes 12, 22 are formed on the corresponding positions on the contact surface, and bolt holes 11, 21 are set on the corresponding positions on the contact surfaces of the first profiled steel 10 and the second profiled steel 20 (can be mass-produced and customized ); there are at least two bolt holes 11,21, which are arranged at both ends of the bracket, and the number of bolts 30 is appropriately increased according to the length of the bracket; the first section steel 10 and the second section steel 20 are connected with the nut 40 with a fl...

The invention relates to solderless duplex section steel which comprises a first section steel body and a second section steel body. The first section steel body and the second section steel body arein back-to-back contact splicing, multiple oval holes are formed in the corresponding positions on the contact faces, bolt holes are formed in the corresponding positions on the contact faces of the first section steel body and the second section steel body, and the first section steel body and the second section steel body are in cooperative connection with nuts through bolts. Accordingly, the duplex section steel welding-free purpose is achieved, the production efficiency is improved through movable connection, and the product yield is guaranteed.
Description
technical field [0001] The invention relates to a welding-free double-combined section steel. Background technique [0002] C-shaped steel is processed by hot coil and cold-bending. The bearing capacity is often selected too large, which increases the construction cost and causes corresponding waste, and the use of double-joint steel can effectively increase the bearing capacity. [0003] Existing double-spin steel: [0004] 1) The double-assembled steel is assembled by welding technology. [0005] There are the following disadvantages: [0006] 1) Double welding increases the content of the process, the progress of manual welding is slow, and the supply is in short supply. Moreover, the gas and sparks generated during the welding process will cause serious harm to the human body and easily cause a fire; [0007] 2) Double stitch welding needs to be preset in the factory and shipped to the site. Contents of the invention [0008] The object of the present invention i...
