According to the base type crown beam provided by the embodiment, the two adjacent crown beams 21 are detachably connected, and when one supporting pile 1 collapses under the action of external force, the crown beam 21 on the collapsed supporting pile 1 can be separated from the adjacent crown beam 21, so that after the supporting pile 1 collapses, only the crown beam 21 on the supporting pile 1 is driven to collapse simultaneously, the phenomenon that other supporting piles 1 collapse synchronously is avoided, and the maintenance cost is reduced; by arranging the hanging ring 22 on each crown beam 21, the crane can drive the crown beam 21 to lift through the hanging ring 22, so that when the crown beam 21 is installed on the support pile 1, the crane can be used for installing the crown beam, the working strength of workers is reduced, and the labor cost is reduced.
Preferably, the height h of the crown beam 21 is 800mm or more, so that the crown beam 21 has sufficient strength.
Further, as shown in fig. 1-2, in the present embodiment, the cross-sectional shape of the cast-in-place hole 211 is a rectangular structure. Of course, the cross-sectional shape of the cast-in-place hole 211 may also be a circular structure or other irregular structures, which is not limited herein.
Further, the connecting piece is made of concrete. Specifically, after the crown beam 21 is placed on the support pile 1, concrete is poured into the cast-in-place hole 211, and the connector is formed after the concrete is solidified.
Further, the top of the support pile 1 is provided with a receiving hole 11, and the receiving hole 11 is communicated with the cast-in-place hole 211 on the corresponding crown beam 21. When concrete is poured into the cast-in-place hole 211, the concrete also flows into the accommodation hole 11 at the same time. By arranging the accommodating holes 11 communicated with the cast-in-place holes 211 on the support piles 1, the contact area between the connecting piece and the support piles 1 can be increased, and the connection stability between the support piles 1 and the crown beam 21 is improved.

In order to ensure the integrity of the crown beam assembly 2, the cross-sectional shape of the convex part 212 and the cross-sectional shape of the groove 213 are both in a T shape, so that the adjacent two crown beams 21 are stably connected, and the connection effect is good.
With reference to fig. 1 to 3, the construction method of the base-type crown beam provided in this embodiment is as follows:
(1) the crane lifts one of the crown beams 21 and places the crown beam 21 on the support pile 1;
(2) fixing the crown beam 21 on the support pile 1 by using a connecting piece;
(3) the crane lifts another crown beam 21, places the crown beam 21 on the support pile 1, and enables the crown beam 21 to be clamped on the adjacent crown beam 21;
(4) and (3) repeating the steps (2) and (3) in sequence until all the crown beams 21 are fixed on the corresponding support piles 1.
According to the base type crown beam provided by the embodiment, the crown beam 21 is hoisted by the hoisting ring 22 on the crown beam 21 through the crane and is placed on the corresponding support pile 1, so that the construction method is simplified, the working strength of workers is reduced, the labor cost is reduced, and the stability is better.
