The base plate 6, baffle 7 and pad 8 adopt a detachable design, which is convenient for replacement and maintenance, and reduces the cost of use.

[0040] The construction steel structure cutting device provided by the utility model has the following working process when in use:

[0041] According to the on-site construction environment, the size and structure of the steel to be cut, and the length and position to be cut, select a limit assembly 5 of appropriate size, install and connect the limit assembly 5 to the gun body 1, and when installing the limit assembly 5, sleeve the connecting portion 61 of the base plate 6 of the limit assembly 5 on the threaded joint 32, then install the gun barrel 2 at the front end of the threaded joint 32, and tighten the tail end of the gun barrel 2 to the threaded joint 32, so as to press and fix the connecting portion 61 of the base plate 6.

[0042] Example 1

[0043] like Figure 3As shown: if there is a supporting position outside the cut steel, the baffle plate 7 in the limit assembly 5 can be selected as the supporting position, and the notch 71 at the rear end of the baffle plate 7 can be slidably sleeved onto the front end of the base plate 6 (the end away from the connecting portion 61), and a screw rod 72 is vertically inserted at the position corresponding to the notch 71 at the rear end of the baffle plate 7, and then the lower end of the screw rod 72 passes through the through groove 62 of the base plate 6, and the lower end of the screw rod 72 is connected to the corresponding screw hole below the rear end of the baffle plate 7, and the screw 72 is tightened to clamp the notch 71 at the rear end of the baffle plate 7 on the upper and lower sides of the front end of the base plate 6, and then contact the supporting position outside the steel through the outer side or inner side of the baffle plate 7, and then the construction personnel hold the device to cut the steel.

[0044] Example 2

[0045] like Figure 4 As shown; if there is no supporting position outside the cut steel, the side of the steel cutting position opposite to the operator is used as the supporting position, so the baffle 7 is not installed, and the pad 8 is installed instead. The pad 8 and the front end of the base plate 6 are connected by the plug block 81 and the pin hole 63, which can quickly complete the connection combination of the pad 8 and the front end of the base plate 6. During use, the gun body 1 is vertically placed so that the bottom of the pad 8 is pressed onto the supporting surface of the steel, and then the gun body 1 is moved to cut the steel.

[0046] Example 3

[0047] like Figure 3-4 As shown, since the limiting component 5 of the device is a detachable and replaceable structure, when the cutting position of the steel is not ideal and the stability during the cutting process cannot be maintained by the single baffle plate 7 and the pad block 8 structure, the baffle plate 7 and the pad block 8 can be combined, that is, the pad block 8 is normally installed on the front side of the base plate 6, and the baffle plate 7 is fixedly installed at the rear end position of the base plate 6. By using the combination of the two at the same time, the purpose of double limiting is achieved, thereby ensuring the stability during the cutting process.

[0048] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
