Abstract
Description
Technical Field
[0001] The utility model relates to a building component, in particular to an assembled steel frame column cap and a building for a cylindrical flat plate beamless floor. Background Art
[0002] Reinforced concrete beamless floor systems are widely used in the floors of industrial and civil buildings at home and abroad. They can significantly save the net height and usable space of the floors, but column caps need to be set at the junction of the column top and the bottom of the slab. At present, column caps are in various forms, such as one-step or multi-step rectangular column caps, circular flat column caps, inverted cone column caps, and four-corner inverted cone prism column caps. The above column caps all expand from the bottom of the slab to the top of the column, which not only causes a large loss of reinforced concrete materials, but also makes the formwork construction quite inconvenient.

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0014] Embodiment 1
[0015] This embodiment discloses an assembled steel frame column cap for a cylindrical flat-plate beamless floor, comprising a plurality of steel splicing units; wherein: Figure 1 As shown, the splicing unit includes an upper arc segment 3, a lower arc segment 4, a support frame 5 and a support plate 6. The upper arc segment 3 and the lower arc segment 4 are distributed up and down and the inner concave surfaces of the two are matched with the outer surface of the cylinder 1. The upper arc segment 3 and the lower arc segment 4 are provided with mounting holes 7 for matching the embedded screws on the cylinder 1. The support frame 5 is distributed and connected between the upper arc segment 3 and the lower arc segment 4, and the support plate 6 is arranged on the upper side of the support frame 5 and the upper arc segment 3; after each splicing unit is installed through the mounting holes 7 and the embedded screws, each upper arc segment 3 and each lower arc segment 4 form a whole circle to surround the cylinder, and each support plate 6 surrounds the whole plate and supports the lower side of the floor panel 2.
[0016] During installation: first calculate the size of each component in the splicing unit according to the stress conditions, and prefabricate the splicing unit, then construct the column 1 and the floor panel 2, set the embedded screws when supporting the formwork, and after the construction is completed, use the embedded screws and the installation holes 7 to install the splicing unit, so that the floor panel 2, the column 1 and each splicing unit form an integral force.
[0017] In this embodiment, preferably: Figure 1 As shown, the support frame 5 is a right triangle, one of which is a right-angled side as a support for the lower part of the support plate 6, the other right-angled side is fixedly connected to the upper arc segment 3 and the lower arc segment 4, and the hypotenuse is used as a diagonal support under the support plate 6; the embedded screw is connected to the internal steel bars of the column 1.
[0018] The number of splicing units is set according to actual conditions. When the size of the cylinder 1 is larger, more splicing units are used.
[0019] The column cap adopts an assembled steel frame structure, which does not require formwork and pouring, is easy to install and simple to construct, saves material usage and project cost, and avoids shear damage to the floor panel 2 caused by the column 1 when the load is large.
