Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
Referring to fig. 1 to 3, the present invention discloses a top connection structure of an existing building, including:
an original cylinder 100 having a first joint surface on an upper surface of the original cylinder 100, the original cylinder 100 including a plurality of original main ribs 110, the original main ribs 110 protruding from the first joint surface, the first joint surface being fixed with a water-swelling sealing-up strip 300;
the newly-built column body 200 is provided with a second joint surface positioned on the lower surface of the newly-built column body 200, and the second joint surface is fixedly attached to the first joint surface; the newly-built column body 200 comprises a section steel column 230 and a plurality of newly-added main ribs 210, wherein the plurality of newly-added main ribs 210 are uniformly distributed on the periphery of the section steel column 230, and each newly-added main rib 210 is connected with one original main rib 110.
In this embodiment, the section steel column 230 is added to realize the up connection of the existing building, and the traditional method of realizing the up connection by means of increasing the cross section and the like is abandoned, that is, the construction cost is saved, the appearance is not damaged, and the stability is improved.
At least one positioning rib 220 is fixed between each new main rib 210 and the section steel column 230, one end of each positioning rib 220 is fixedly connected with the new main rib 210, and the other end of each positioning rib 220 is fixedly connected with the outer side wall of the section steel column 230.
In this embodiment, four newly-added main ribs 210 are uniformly distributed on the periphery of the section steel column 230, that is, the four newly-added main ribs 210 are fixed to the periphery of the section steel column 230 at the same time, so that the section steel column 230 is prevented from shaking or skewing before being poured.
One end of the positioning rib 220 is bent upwards along the outer side wall of the section steel column 230 to form a bent portion, and the bent portion is attached to the outer side wall of the section steel column 230 and is welded and fixed.
Specifically, one end of the positioning rib 220 is fixed to the newly added main rib 210, and the other end of the positioning rib is bent to a shape fitting the outer periphery of the section steel column 230 and then welded and fixed thereto, so that the contact area between the positioning rib 220 and the section steel column 230 is increased, and the connection strength is further improved.
The section steel column 230 includes an i-steel 231 and a stiffening plate 232 fixed to one end of the i-steel 231, and the stiffening plate 232 is provided with a through hole for fixing the section steel column 230 to the original column 100.
