Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1-4, the splicing structure for preventing stress deflection provided by the utility model comprises a main beam 10, a stand column 20 and a column top connecting piece 30, wherein the main beam 10 and the stand column 20 are all C-shaped sections, the directions of the notch of the main beam 10 and the notch of the stand column 20 are the same, two ends of the column top connecting piece 30 are respectively connected with the main beam 10 and the stand column 20 through fastening bolts 31, the vertical projection of the stand column 20 coincides with the vertical projection of the main beam 10, namely, in the connection state, the vertical projection of the stand column 20 coincides with the vertical projection of the main beam 10, the line centers of the two main members of the stand column 20 and the main beam 10 are closer, and the notch of the main beam 10 and the notch of the stand column 20 face the same direction.

Specifically, compared with the prior art, through adopting the post top connecting piece 30 as the intermediate connection spare for the perpendicular direction projection of stand 20 and the perpendicular direction projection of girder 10 can coincide each other, and girder 10 and stand 20's notch orientation same direction, girder 10 can the vertical support on stand 20 promptly, compare in the past girder 10 and stand 20 back-to-back's connected mode, can avoid the line heart of girder 10 and the line heart of stand 20 excessively deviate, lead to the connected node because atress skew, lead to the damage, improve connected node's structural strength.

Further, the column top connecting piece 30 adopts a C-shaped section, and the notch direction of the column top connecting piece 30 is opposite to the notch directions of the main beam 10 and the upright column 20, so that the structural strength of a connecting node can be further improved by matching the main beam 10 with the upright column 20, and the stress on the upper part can be effectively transferred to the upright column 20.

Further, the cross section of the column top connecting piece 30 is smaller than that of the column 20, the column top connecting piece 30 is made of aluminum-plated magnesium-zinc steel plates, the thickness is not smaller than 3mm, the yield strength is not smaller than 450mpa, the structural strength of the column top connecting piece 30 is ensured, the material consumption of the column top connecting piece 30 is reduced, the overall cost is reduced, and the corrosion resistance of the column top connecting piece 30 is improved.
