Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to an ultra-thick raft slab reinforced steel support structure. Background Technology

[0002] In super high-rise buildings and large-scale infrastructure projects, ultra-thick raft slabs (often exceeding 3 meters in thickness) require multiple layers of dense steel mesh as the foundation load-bearing structure. Traditional support methods using welded steel supports have significant drawbacks: these supports are susceptible to deformation under construction loads, affecting structural stress; the impact of concrete pouring can easily cause instability, leading to displacement of the steel mesh or even collapse. For example, patent number 202420358598.0 discloses "a modular multi-layer steel support for ultra-thick raft slabs," which has poor stability and cannot effectively support the intermediate layers of steel reinforcement. Utility Model Content

[0003] The purpose of this utility model is to provide an ultra-thick raft slab reinforced steel support structure.

[0004] This utility model is achieved through the following measures: an ultra-thick raft slab reinforced steel support structure, characterized in that it includes a number of matrix-distributed I-beam columns, angle steel set on the wing plates of two horizontally adjacent columns, and T-beams set in the grooves of two vertically adjacent columns. The T-shaped steel is located above the angle steel, and both the vertical part of the T-shaped steel and the vertical part of the angle steel are provided with grooves that cooperate with the reinforcing bars. When the longitudinal reinforcement of the raft foundation is placed in the groove of the angle steel and the transverse reinforcement is placed in the groove of the T-shaped steel, the transverse reinforcement and the longitudinal reinforcement are in contact. Several angle steels and T-shaped steels are provided along the height direction of the column.

[0005] Furthermore, both ends of the angle steel are fixed with end plates, and each end plate is fixed with a right-angled steel plate that slides along the outer edge of the flange. The lower end face of the horizontal part of the T-shaped steel contacts the upper end face of the right-angled steel plate. (Generally, welding is used for fixing.) Furthermore, a threaded sleeve is fixedly provided on the end plate, and a stud is provided inside the threaded sleeve through a threaded connection. A through hole is opened on the end plate to cooperate with the stud.

[0006] Furthermore, a bottom steel plate is fixedly installed at the lower end of the column.

[0007] Furthermore, a diagonal brace is fixedly installed between two horizontally adjacent columns, with the upper end of the diagonal brace located above the T-shaped steel and the lower end of the diagonal brace located below the angle steel.

[0008] Furthermore, the diagonal braces have two layers of reinforcing bars. These two layers of reinforcing bars are not the top and bottom layers of the raft foundation. Usage: After the raft foundation is accepted, mark the column matrix according to the design spacing; the longitudinal and transverse spacing depends on the construction requirements. Vertically weld the I-beam columns to the bottom steel plate (the bottom steel plate is generally welded to the bottom plate); install angle steel between the transverse adjacent column flanges, sliding the right-angle steel plate to reach the design elevation, and temporarily fix the angle steel with rotating studs. Insert T-shaped steel into the grooves of the longitudinal adjacent columns, ensuring the lower surface of its horizontal part abuts against the upper surface of the right-angle steel plate; install the angle steel and T-shaped steel layer by layer according to the floor height requirements. After installation, check the position of the angle steel and T-shaped steel in each layer; loosen the studs and adjust any that are not up to standard. Weld diagonal braces between the column matrix, ensuring the diagonal braces are located between the two layers of reinforcing bars. Embed the longitudinal reinforcing bars into the angle steel grooves, and the transverse reinforcing bars into the T-shaped steel grooves; adjust the reinforcing bars so that the longitudinal / transverse reinforcing bars are in direct contact at the intersection points.

[0009] The beneficial effects of the technical solution provided by this utility model embodiment are: the overall stability can be increased by the matrix arrangement of I-beam columns; the angle steel and T-beams can effectively support the multi-layer steel bars; the spacing between each layer can be checked and fine-tuned, thus improving the construction quality.
