AI Technical Summary
The existing construction method of the corner nodes at the overlap of the tire frame I-beams requires measuring and cutting the I-beams, which prolongs the construction period and makes it difficult to control the quality, affecting the stability of the nodes.
Prefabricated steel plates are used to overlap the I-beams. The prefabricated steel plates are prefabricated in the factory and welded to the ends of the I-beams to avoid on-site cutting and ensure node stability.
There is no need to cut I-beams on site, which shortens the construction period, improves the stability and processing quality of the node, increases the welding area, and ensures the stability of the node.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of steel structures, and in particular relates to an angle node at a lap joint of an I-beam of a tire frame and a tire frame. Background Art
[0002] like Figure 1 As shown, the tire frame is generally made of I-beams, which are overlapped at different positions to form different nodes. For the corner nodes at the overlapped I-beams of the tire frame, the current construction method is: first measure the dimension L from the web of the I-beam to the edge of the flange, such as Figure 2 As shown, the upper and lower flanges of one I-beam's end area are then cut, leaving the web protruding forward by a length L. This protruding web is then inserted into the slot of another I-beam and welded. This construction method requires measuring and cutting the I-beam, a complex operation that delays construction and makes it difficult to control the cutting dimensions. This can easily lead to process acceptance failures or welding or cutting rework. In actual experience, excessive cutting often results in a small weld contact area and compromises joint stability. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] Example 1
[0020] This embodiment provides a corner node at the overlap of a tire frame I-beam, including an I-beam A, an I-beam B and a prefabricated steel plate 1; Figure 3 and Figure 4 As shown, I-beam A and I-beam B are arranged at right angles at the ends, and the upper flange plate 2 and lower flange plate 4 of I-beam A are aligned with the upper flange plate 2 and lower flange plate 4 of I-beam B respectively and welded; Figure 3 and Figure 4As shown, the prefabricated steel plate 1 is distributed on both sides of the web 3 of I-beam A. A portion of the prefabricated steel plate 1 is located in the groove of I-beam A and abuts the web 3 of I-beam A, while the other portion is located in the groove of I-beam B and its sides abut the web 3 of I-beam B. The two sides of the prefabricated steel plate 1 are welded to the webs 3 of I-beam A and I-beam B, respectively. The top side is welded to the upper flange plates 2 of I-beam A and I-beam B, and the bottom side is welded to the lower flange plates 4 of I-beam A and I-beam B. The prefabricated steel plate 1 can be designed and manufactured in advance, eliminating the need for on-site cutting of I-beams. This reduces construction difficulty and shortens construction time, while also ensuring processing quality and not affecting node stability. The prefabricated steel plate 1 is simultaneously located in the grooves of two I-beams and welded to both, increasing the welding area and contact area of the two I-beams and improving node stability.
[0021] The size of the prefabricated steel plate 1 must be reasonable. Since it is manufactured in the factory, the size can be well controlled. In this embodiment: the length of the prefabricated steel plate 1 exceeds the width of the groove of the I-beam B by 20-30 mm, ensuring that the prefabricated steel plate 1 is simultaneously located in the grooves of the two I-beams and has sufficient contact area with both; there is a gap between the prefabricated steel plate 1 and the grooves of the I-beam A and the I-beam B in the height direction, and the gap is preferably 2-5 mm. The existence of a certain gap can facilitate better placement and welding of the prefabricated steel plate 1.
[0022] In this embodiment, the welding positions between the I-beam A and the I-beam B, between the prefabricated steel plate 1 and the I-beam A, and between the prefabricated steel plate 1 and the I-beam B are all fully welded. The welding slag generated during the welding process needs to be cleaned in time, and the welding points need to be subjected to weld flaw detection.

During construction: first design the size of the prefabricated steel plate 1 according to the size of the I-beam and process it in the processing plant. The prefabricated steel plate 1 must pass the relevant quality inspection before the relevant overlap can be carried out; then on site, first align and weld the upper flange plate 2 and lower flange plate 4 of the I-beam A with the upper flange plate 2 and lower flange plate 4 of the I-beam B respectively, and then put the prefabricated steel plate 1 into the groove of the I-beam A and the I-beam B, so that it is attached to the web 3 of the I-beam A and against the web 3 of the I-beam B, and weld the two side edges of the prefabricated steel plate 1 to the web 3 of the I-beam A and the I-beam B respectively, weld the top edge to the upper flange 2 of the I-beam A and the I-beam B, and weld the bottom edge to the lower flange 4 of the I-beam A and the I-beam B. After the welding of the prefabricated steel plates 1 on both sides of the web 3 of the I-beam A is completed, the current angle node is completed; after the installation of part of the tire frame is completed, the relevant functionality and installation stability acceptance are carried out, and large-scale assembly is carried out after the acceptance is qualified.
