Description

Technical Field

[0001] This utility model belongs to the field of purlin installation technology, specifically relating to a precision measuring device for purlin installation. Background Technology

[0002] Purlins are the core horizontal components of a building's roof structure, installed perpendicular to the roof trusses or rafters. Their primary function is to support the roof material and transfer loads to the main structure. As lateral bending members, they are typically designed as single-span simply supported members to simplify the stress model. Based on their construction, they can be divided into solid-web and truss types. In modern engineering, the main purlins connect to columns and beams to bear the main loads, while secondary purlins assist in enhancing stability, together forming the "skeleton" of the roof system.

[0003] When installing purlins, it is necessary to determine the angle between the purlin and the roof beam. To ensure quality, this angle needs to be highly accurate. A common measurement method is to use a spirit level. However, the spirit level is too short to measure the purlin angle completely in one go. A common high-precision measurement and adjustment method is to use a total station on the ground. However, this requires at least two people to operate: one to measure with the total station and the other to adjust the purlin angle. Once the purlin angle meets the standard, it is fixed. This installation requires communication between two people, which reduces installation efficiency. Utility Model Content

It employs an angle adjustment structure to indicate the installation angle of the purlin, and the overall length of the measuring contact structure is adjustable, thus providing a more complete reflection of the angle of the entire purlin.

[0019] As a preferred embodiment, the four fixing structures further include: a fixing frame 9, a horizontal fixing bolt 10, a vertical fixing block 11, and a vertical fixing bolt 12; the fixing frame 9 is installed on the lower wall of the measuring binding base 1, the horizontal fixing bolt 10 is installed inside the fixing frame 9 by means of threads, the vertical fixing block 11 is installed at the tail of the horizontal fixing bolt 10 by means of a rotating seat, the vertical fixing bolt 12 is installed inside the vertical fixing block 11 by means of threads, and a vertical fixing plate 14 is installed on the upper wall of the vertical fixing bolt 12.

[0020] Working Principle: Purlins need to be installed on the upper wall of the roof steel frame beam. There are two installation methods for purlins: one is to keep them parallel to the upper wall of the roof steel frame beam, and the other is to have a certain angle with the upper wall of the roof steel frame beam. The operator first places the measuring and binding base 1 on the upper wall of the roof steel frame beam, and the roof steel frame beam and the measuring and binding base 1 are directly equipped with four anti-slip feet 13. The operator first rotates the four horizontal fixing bolts 10 respectively, so that the vertical fixing bolts 12 are located on the lower wall of the roof steel frame beam. Then, the operator rotates the vertical fixing bolts 12, and under the action of the threads, the vertical fixing bolts 12 move upward inside the vertical fixing block 11 until the vertical fixing plate 14 contacts the lower wall of the roof steel frame beam, and the measuring and binding base 1 is fixed to the upper wall of the roof steel frame beam. Next, the operator adjusts the purlin installation angle. For horizontal installation, the operator positions the angle adjustment seat 3 at the two angle adjustment rings 2 and secures it with bolts. The outer walls of the two angle adjustment rings 2 have angle scale lines, directly reflecting the angle of the angle adjustment seat 3. Since the two angle adjustment rings 2 are fixedly mounted on the upper wall of the measuring and binding base 1, the angle between the angle adjustment rings 2 and the measuring and binding base 1 is fixed. The operator can determine the angle of the angle adjustment seat 3 by comparing the scale lines on the shaft of the angle adjustment seat 3 with the angle scale lines on the angle adjustment rings 2. Finally, the angle adjustment seat 3 and the two angle adjustment rings 2 are relatively fixed with bolts. At this point, the angle between the measuring beam 6 and the roof steel frame beam is the purlin installation angle. The operator then pulls out the two measuring movable seats 7 and secures the measuring beam 6 and the two measuring movable seats 7 relatively with bolts. At this point, the operator places the purlin on the upper wall of the roof steel frame beam and initially fixes it. Then, the operator rotates the height adjustment screw 4, which, under the action of the thread, moves the measuring beam 6 up and down until the measuring contact plate 8 can contact the purlin. The operator adjusts the purlin so that both measuring contact plates 8 can contact the purlin simultaneously. At this point, the angle of the purlin reaches the installation angle, and welding or other methods of fixing can be carried out.
