Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a visual adjustment device for the installation position of a prestressed concrete beam corrugated pipe. Background Art

[0002] During the construction of the adhesive structure, the corrugated pipes need to be installed and fixed according to the prestressed curve design drawing, and the overall installation is parabolic. During the installation of the corrugated pipe, in order to ensure the accurate installation position of the corrugated pipe, the curve position of the corrugated pipe is usually marked on the beam stirrups with paint according to the curve design drawing, and the node in the middle of the corrugated pipe is installed on the bracket, so that the corrugated pipe is curved as a whole.

[0003] Traditional brackets use steel bars welded to the beam waist bars or stirrups, and then use wire to fix the middle part of the corrugated pipe to the bracket bars. Since the height of the bracket is difficult to control, the height node position of the middle part of the corrugated pipe is inaccurate, and the corrugated pipe is easy to fall off the bracket during the bracket construction and fixing process. Utility Model Content

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] Provided is a visual adjustment device for the installation position of a prestressed concrete beam corrugated pipe, comprising an I-shaped pipe fixed on an external prestressed concrete beam structure, wherein an angle steel is sleeved on the belly pipe of the I-shaped pipe, the belly pipe is provided with an external thread, and the belly pipe is threadedly connected with two nuts respectively located on the upper and lower sides of the angle steel; the angle steel is fixedly connected to the middle node of the corrugated pipe, and a scale steel bar is vertically provided on the angle steel.

[0007] In this solution, the height of the angle steel is adjusted by adjusting the positions of the two nuts on the belly tube of the I-tube, thereby facilitating the adjustment of the installation height of the corrugated pipe on the angle steel, and the installation position accuracy of the corrugated pipe is improved by observing the scale on the scale steel bar.

[0008] Furthermore, the two wing tubes of the I-shaped tube are round steel tubes, and the belly tube of the I-shaped tube is threaded steel. Round steel tubes and threaded steel tubes are easy to obtain and process.

[0009] Furthermore, the diameters of the two wing tubes and the belly tube are both 22 mm.

[0010] Furthermore, the angle steel is an L-shaped plate structure, and the angle steel includes a vertically connected horizontal plate and a vertical plate, a through hole is provided in the middle of the horizontal plate, a scale steel bar is fixed on the end of the horizontal plate away from the vertical plate, and a corrugated pipe is fixed on the end of the horizontal plate close to the vertical plate. The outer wall of the corrugated pipe contacts the vertical plate, so that the vertical plate can play a limiting role.

[0011] Furthermore, the bellows is welded to the transverse plate of the angle steel, and the welding ensures the connection strength.

[0012] Furthermore, the scale steel bar is welded to the transverse plate of the angle steel.

[0013] Furthermore, two washers are sleeved on the web of the I-shaped tube, and both washers are located between the two nuts and respectively on the upper and lower sides of the angle steel. The arrangement of the washers can prevent the nuts from directly contacting the angle steel, thereby providing a contact area and reducing wear.

[0014] Furthermore, the length of the scale steel bar is equal to the height of the I-tube.

[0015] The utility model discloses a visual adjustment device for the installation position of a prestressed concrete beam corrugated pipe, and its beneficial effects are:
