In recent years, some new slip construction practices have been created in engineering practice to avoid the problem of overlong the longitudinal direction of the structure, as shown in fig. 1, for such problems.
However, the structure has the problem that when the temperature deformation is large, especially when the temperature shrinks, due to the randomness of the positions of the bolts in the long round bolt holes, the bolts are possibly deviated from the original positions during the original installation, so that the actual placing points of the secondary beams are far away from the central axis position of the main beam, the main beam is greatly deviated, the main beam is excessively twisted, and the stress safety of the main beam is seriously adversely affected. Therefore, for the structure with the longitudinal length of the roof exceeding the specification limit value, a more appropriate construction node is needed to avoid the safety problem possibly brought by the common node.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 2-3, the present invention provides a technical solution: a main beam anti-slip connection structure suitable for a large-temperature deformation roof comprises a main beam 1, a convex surface support plate 2, a convex surface support plate and a convex surface support plate; convex support plates 2 mounted on the main beams 1 are used to bear the pressure from the secondary beams 3.
Furthermore, the main beam 1 and the secondary beam 3 are connected through an oblong bolt hole 5 and a common bolt 4.
Further, the convex support plate 2 is mounted as follows: the main beam 1 is installed firstly, then the secondary beam 3 is installed, the web plate of the secondary beam 3 is supported on the convex surface support plate 2 during installation, and finally the common bolt 4 is installed in the long round bolt hole 5.
Furthermore, the convex surface bearing plate 2 comprises a rectangular lower part with a rectangular cross section and an arc-shaped upper part with an arc-shaped cross section, the rectangular lower part is arranged on the main beam 1, and the convex surface on the arc-shaped upper part is connected with the secondary beam 3.
Further, the relative positions of the convex supporting plates 2 and the main beams 1 are fixed.
Further, convex support plates 2 are welded to the main beams 1.
Further, the secondary beam 3 is supported on the primary beam 1 by means of convex support plates 2.
Further, when the secondary beam 3 longitudinally expands and contracts, the action point of the reaction force transmitted to the main beam 1 by the secondary beam 3 is fixed.
Further, a horizontal supporting plate 6 is arranged between the main beam 1 and the convex supporting plate 2, and the horizontal supporting plate 6 is fixedly connected with the main beam 1 and the convex supporting plate 2.
The working principle is as follows: when the temperature of the secondary beam 3 changes, the secondary beam 3 contracts or extends, deformation occurs along the long round bolt hole 5, and the convex surface bearing plate 2 is arranged on the main beam 1, so that the secondary beam 3 is supported on the main beam 1 through the convex surface bearing plate 2, the convex surface bearing plate 2 is welded on the main beam 1, and the relative position between the main beam 1 and the secondary beam 3 is fixed, therefore, when the secondary beam 3 longitudinally extends and retracts, the action point of the reaction force transmitted to the main beam 1 is fixed, thereby avoiding the action point transmitted to the main beam 1 by the secondary beam 3 from changing due to the deformation of the secondary beam 3, and further avoiding the occurrence of the situations that the main beam 1 additionally bears the torque action and the like caused by the change.
