Embodiment Construction

[0036] Examples see Figure 1-3 As shown, a support structure for foundation floor steel column installation, including cushion layer 1, waterproof layer 2, waterproof protection layer 3, embedded components, support frame, support plate 10, embedded steel column 12 and embedded shear member 11 .

[0037] The cushion layer 1 is located at the bottom, the waterproof layer 2 is fully spread on the upper surface of the cushion layer 1 , and the waterproof protective layer 3 is fully spread on the upper surface of the waterproof layer 2 .

[0038] The pre-embedded assembly includes a horizontal pre-embedded connection plate 4 , the upper surface of the pre-embedded connection plate 4 is flush with the upper surface of the waterproof protection layer 3 .

[0039] The support frame includes a set of support columns 7, the number of the embedded connecting plates 4 is the same as that of the supporting columns 7, and the bottom of the supporting columns 7 is connected to the upper s...

Abstract

The invention discloses a foundation bottom plate steel column installation supporting structure and a construction method. The structure comprises a cushion layer, a water-proof layer, a water-proofprotecting layer, a pre-buried assembly, a supporting frame, a supporting plate, a pre-buried steel column and a pre-buried shear-resisting part. The pre-buried assembly comprises horizontal pre-buried connecting plates; the supporting frame comprises a set of supporting columns; the bottom ends of the supporting columns are connected with the upper side surfaces of the pre-buried connecting plates; the pre-buried assembly further comprises pre-buried supporting legs; and a pi shape is formed between each row of pre-buried supporting legs and the corresponding pre-buried connecting plate. Theproblem that the pre-buried steel columns in an existing bottom plate cannot be fixedly installed can be effectively solved by means of a supporting device of installation of a foundation bottom platesteel column, the position of the angle iron supporting frame is adjusted by adjusting the positions of the pre-buried connecting plates, the buried elevation of the pre-buried steel column is met byadjusting the specification and size of the angle iron supporting frame and replacing different supporting plates, thus the accuracy of the pre-buried steel column is effectively improved, meanwhilethe supporting demand of installation of the pre-buried steel column can be met, and the safety and the stability of installation of the pre-buried steel column are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a support structure for installation of foundation floor steel columns and a construction method thereof. Background technique [0002] With the rapid development of high-rise buildings in our country, the application of steel reinforced concrete structures will become more and more extensive. Stiff steel reinforced concrete has the advantages of high strength, small cross-sectional size of components, strong binding force with concrete, saving concrete, increasing use space, and reducing project cost. [0003] In buildings such as high-rise residences and apartments, H-shaped steel is placed in columns or shear walls to enhance the bearing capacity and reduce the axial compression ratio of components while saving area and compressing the section of vertically stressed components. When installing H-shaped steel columns, there are high requirements for size position...
