Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building construction, specifically relates to a positioning device for the bottom of steel pipe frame on shaped steel. BACKGROUND

[0002] In the field of building construction, industrial equipment installation, etc., steel pipe frames are often set up for high-altitude operations or to support other structures. Currently, the method of fixing the steel pipe frame on the top of I-shaped steel or C-shaped purlin is relatively complex, and the fixing effect is not ideal. The traditional fixing method may require permanent connections such as welding, which not only makes installation and removal troublesome, but also may cause damage to the I-shaped steel or C-shaped purlin. In addition, the existing fixing device is difficult to adapt to steel pipe frames and I-shaped steel or C-shaped purlin of different sizes, and has poor universality. In scenarios where temporary work platforms need to be quickly set up and removed, the existing fixing method is inefficient and cannot meet actual needs. SUMMARY

[0003] The utility model provides a kind of positioning device for the bottom of steel pipe frame on shaped steel, which can conveniently and quickly fix the steel pipe frame on the top of I-shaped steel or C-shaped purlin, and is removable and has strong universality.

[0004] A positioning device for the bottom of steel pipe frame on shaped steel includes replaceable sockets, C-shaped steel and angle steel. The replaceable sockets are connected to the C-shaped steel through threads, and the C-shaped steel is welded to the angle steel. The replaceable sockets are composed of steel pipes, backing plates and threaded rods. The backing plates are welded to the lower surface of the steel pipes, and the threaded rods are welded to the lower surface of the backing plates. The C-shaped steel has connecting holes and coaxially welded nuts below the connecting holes.

[0005] One of the angle steel's edges has two bolt holes, and nuts are welded to the upper surface of the bolt holes. The bolt holes and nuts are coaxial, and bolt rods are arranged on the nuts.

[0006] According to the steel pipe support position and pipe diameter of the upper frame body of the steel structure, the utility model is installed at the corresponding position. The replaceable sockets of the utility model are adjusted according to the pipe diameter of the steel pipes of the upper frame body, and the stability and safety of the frame support end of the steel pipe with different pipe diameters in the steel structure are realized.

[0007] The actual application results show that the utility model has high installation precision and stability, and has important practical application value.

[0008] The precise structural design and efficient installation method ensure the stability and safety of the device.

[0009] The replaceable pipe diameter socket is easy to install on the shaped steel to adapt to steel pipe frames with different sizes and pipe diameters.

[0010] The utility model discloses have the advantages that convenient installation and dismounting, construction personnel can accurately, quickly install the utility model in the specified position of the shaped steel according to the actual situation on site.

[0011] The replaceable property of the replaceable socket greatly improves flexibility and applicability. Steel pipe frames of different specifications can realize stable butt joint by replacing steel pipe sockets matched therewith.

[0012] The steel pipe of the upper frame body can be directly inserted into the replaceable socket, and a close and stable fitting relationship is formed between the steel pipe and the socket. BRIEF DESCRIPTION OF DRAWINGS

[0019] Figure 1 , Figure 2 , Figure 3 As shown in the figure, a positioning device for the bottom of a steel pipe frame on a shaped steel includes a replaceable socket 1, a C-shaped steel 21, and an angle steel 22. The replaceable socket 1 is connected to the C-shaped steel 21, and one end of the C-shaped steel 21 is welded to one edge of the angle steel 22.

[0020] Figure 4 As shown in the figure, the replaceable socket 1 is composed of a steel pipe 11, a base plate 12, and a threaded rod 13. The base plate 12 is welded to the lower surface of the steel pipe 11, and the threaded rod 13 is welded to the lower surface of the base plate 12.

[0021] The base plate is a circular steel plate with a diameter equal to that of the steel pipe.

[0022] The C-shaped steel 21 has a connecting hole in the center of its surface, and a nut 211 is welded to the lower surface of the C-shaped steel 21 coaxially with the connecting hole.

[0023] The threaded rod 13 is connected to the nut 211 by thread.

[0024] Angle steel 22 has two bolt holes on one corner, and nuts 221 are welded to both bolt holes. The bolt holes and nuts 221 are coaxial, and two bolt rods 23 are respectively set on the two nuts 221.

[0025] How to use this utility model:

[0026] Select a replaceable bearing with an appropriate pipe diameter based on the diameter of the steel pipe used in the upper frame.

[0027] Figure 5 As shown, place this utility model on the double-segment C-shaped purlin 3, align the center of force of this utility model with the central axis of the double-segment C-shaped purlin, and tighten both screws 23 tightly against the inner side of the wing plate of the double-segment C-shaped purlin 3 to confirm that this utility model is securely installed.
