The lower surface of the bottom plate 7 is also provided with supporting feet 9.
Because the load that meets when the construction differs, provide two kinds of proposals of adjusting the overall height of split heads muscle here:
the first scheme is as follows: when the plate thickness is thin and the side load is small, the height of the main supporting leg 1 at the uppermost part of the horse stool bar or the height of the supporting leg 9 can be adjusted to adjust the whole height.
Scheme II: when the plate is thick, the height of the main supporting leg 1 at the uppermost part of the split heads rib or the height of the supporting leg 9 cannot be well supported, because the split heads rib is subjected to a large lateral load, if the method adopts the first scheme to adjust the height, the overall stability is reduced, and when the large lateral load (such as concrete pouring) is met, a large bending moment is generated at the joint of the main supporting leg 1 and the upper reinforcing steel bar, so that the stress is unreasonable. Therefore, when the plate thickness is thick, the problem of the plate thickness can be solved by enlarging the whole proportion of the split heads. Therefore, the stability of the whole body can be ensured, and the large lateral load brought by concrete pouring can be borne.
Installation process:
And 2, after the sizes of the components are determined, manufacturing a mold in a factory, and pouring out the components through the mold.
And 3, prefabricating all the components of the horse stool rib with the tree structure in a factory. Wherein the diameters of the respective connecting rods are set to the same value for the convenience of manufacture. Make the unified stock of an organic whole with each connecting rod, according to the length needs of difference, cut the stock in order to acquire second branch supporting leg 6 and first branch supporting leg 4.
And 4, digging out the middle solid parts on the branch connector 5 and the main connector 2 poured out of the mold, and manufacturing a hollow sleeve for inserting the main supporting leg 1, the first branch supporting leg 4 and the second branch supporting leg 6.
And 6, assembling the manufactured parts. And the parts are tightly connected and cannot slide out or fall off in the assembling process.
And 7, transporting the assembled completely-assembled split heads to a construction site.
And 8, fixing the main support leg 1 at the top of the split heads with a certain single steel bar of the upper steel bar mesh. The split heads are placed on the lower steel mesh sheet. And whether the connection between each component is firm or not is checked, and the component is prevented from falling off.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
