Description
Technical Field
The utility model relates to a control flange dish straightness device that hangs down.
Background
During the assembly of the traditional steel structure with the flange plate, the pipe column is placed on the horizontal jig frame firstly, then the flange plate is lifted, the verticality of the flange plate and the pipe column is ensured through a plumb line, the position of the pipe column is adjusted simultaneously, the pipe column is positioned in the center of the flange plate, spot welding and reinforcing plate installation are carried out, and 2 and 3 persons are required to be matched and constructed simultaneously in the assembly process to complete the assembly. The vertical verticality of the flange joint is the key for ensuring the overall construction quality.
Disclosure of Invention
The utility model aims at overcoming prior art's defect, provide a control flange dish straightness device that hangs down, straightness that hangs down between control flange dish that can be very convenient and tubular column improves the assembly accuracy.
In order to solve the technical problem, the utility model discloses a realize like this:
the utility model provides a control flange dish straightness device that hangs down which characterized in that: the device comprises a first support arm, a second support arm, a third support arm and a connecting arm; the lower end of the first support arm is vertically attached to the pipe wall of the circular pipe, the lower end of the second support arm is vertically attached to the pipe wall of the circular pipe and the inner wall of the flange plate on one side of the pipe wall of the circular pipe, one side of the third support arm is vertically attached to the outer side of the flange plate, and the connecting arm is connected with the upper ends of the first support arm, the second support arm and the third support arm to connect the first support arm, the second support.
The device for controlling the perpendicularity of the flange plate is characterized in that: the length of the third support arm is not less than the diameter of the flange.
The utility model has the advantages that: the labor is saved; the working efficiency is improved; the assembly precision is improved, and the problem that the perpendicularity between the drawing disc and the circular tube cannot be guaranteed once in the construction process is solved; the material is saved, and the secondary utilization of corner predictions is realized.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
fig. 1 is a schematic structural diagram of the present application.
Detailed Description
As shown in fig. 1: a device for controlling the perpendicularity of a flange plate comprises a first support arm 1, a second support arm 2, a third support arm 3 and a connecting arm 4; the lower end of the first support arm is vertically attached to the pipe wall of the round pipe 5, the lower end of the second support arm is vertically attached to the pipe wall of the round pipe and one side of the second support arm is attached to the inner wall of the flange 6, one side of the third support arm is vertically attached to the outer side of the flange, and the connecting arm is connected with the upper ends of the first support arm, the second support arm and the third support arm to connect the first support arm, the second support arm and the third support arm into a whole.
The length of the third support arm is not less than the diameter of the flange, the length of the third support arm for attaching the flange is preferably the length of the flange covering the diameter of the flange, and the third support arm passes through the circle center of the flange to ensure that the third support arm is on the diameter of the flange, so that the device is prevented from tilting left and right;
the material used for manufacturing the device requires:
the device should be made of a material with high strength, so that a large use error caused by deformation in use is avoided;
the rigidity of the material is required to meet the requirements that in the actual use process, the first support arm 1 is horizontally attached to the outer wall of the circular tube, the second support arm 2 is attached to the wall of the circular tube and the flange, and the third support arm is attached to the flange (the perpendicularity of the flange and the circular tube body is tested), so that the whole device cannot deform and the actual precision is influenced in the actual operation process;
the weight of the device meets the requirement that each operator can take the device and if the device is placed improperly, the device slides to the ground without hurting the foot surface.
In order to ensure the accuracy of the device, software programming numerical control cutting blanking is adopted, and for the contact surfaces of the third support arm, the connecting arm and the flange plate, the contact surfaces of the first support arm, the second support arm and the pipe wall adopt an end milling process, so that the verticality and the planeness of the contact surfaces of the third support arm, the connecting arm and the flange plate and the error ranges of the contact surfaces of the first support arm, the second support arm and the pipe wall meet the requirements of GB50205-2020 acceptance Standard for construction quality of Steel structures.
The first support arm 1 and the second support arm 2 are attached to the pipe wall of a round pipe horizontally placed on the jig frame, and the third support arm 3 and the second support arm 2 clamp a flange plate needing to test verticality. The verticality of the circular tube and the flange plate is ensured by the fitting degree of the third support arm 3 and the outer wall of the flange plate.
In the in-service use process, fix ring flange and post body through first support arm 1, second support arm 2, third support arm 3, ensured that ring flange and tubular column can not take place the skew of position in carrying out welding process to guarantee the straightness that hangs down of ring flange and post body, simultaneously because the shape characteristics of this device, still and have the inspection effect to the ring flange straightness that hangs down when the welding is accomplished concurrently.
In use, the following steps may be followed:
horizontally placing a circular tube to be assembled with a flange plate on a jig frame;
positioning the flange plate in a spot welding mode according to the assembly size of the construction drawing;
avoiding the positioning points, and clamping the flange plate on the round pipe according to the work management of the book at the bottom of the book, so as to ensure the perpendicularity of the flange plate and the round pipe;
finishing final welding according to a construction drawing;
taking down the device;
use this application device, carry out the retest of secondary to the pipe fitting that the dress has welded.
