Steel erect column concrete pedestal

The present invention relates to a steel erect column concrete pedestal, in particular to a concrete (or cement mortar) and reinforced concrete forming a transportable moving unit for quick and easy installation of a steel erect column Concrete foundation for (for example: H-beam, I-steel, etc.).

At present, the construction of metal factories, scaffoldings, houses, street lamps or the like is usually erected on the ground by erecting the vertical columns according to the design coordinates determined by the design plan. If a strong support strength is required, the upright column can generally be formed as an upright column made of H-beam, I-beam or the like. The steel vertical column is generally welded at its lower end to a bottom end plate, and a plurality of through-holes are formed in the bottom end plate.

It is known that the mounting brackets of such steel straight columns are usually placed on the ground of the designed coordinate point, and the pits or slots for constructing the foundation are first dug, and the four welded joints of the steel bars are vertically spaced apart from each other. The high-pull screw (shown in Figure 1) is erected upright in the pre-excavated pit or trough, and then poured into the pit or trough with cement mortar or concrete slurry to make the threaded section of the upper end of the high-pull screw protrude. Exposed to the cement mortar or concrete upper surface (as shown in Figure 2). When the cement mortar or concrete poured into the pit or the tank is stably solidified, the high-tilt screw is stably fixed to the solidified cement mortar or concrete; The steel vertical column can be erected on the surface of the stabilized solidified cement mortar or concrete, so that the protruding portion of the high tensile screw exposed on the upper surface of the poured cement mortar or concrete penetrates the threaded section The through-mounting hole of the bottom end plate of the type steel straight column is fixed to the threaded section of the upper end of the vertical high-pull screw by a nut, and the steel vertical column can be installed and erected.

The installation of the steel straight column is carried out in the above-mentioned conventional manner. Because the high-pull screw needs to be buried in the excavated pit or trough and then the cement mortar or concrete is poured on the site, the rain or soil loosening makes the construction operation more complicated. It is cumbersome and the quality of construction is reduced. In addition, because cement mortar or concrete takes a long time to maintain, it can increase the strength and bear the heavy pressure. Therefore, the steel vertical column must wait until the cement mortar or concrete fixed with the high-drawing screw is strong enough to withstand the heavy pressure. To the extent that the installation can be combined with a high-pull screw, otherwise the weight of the steel vertical column may cause the cement mortar or concrete underneath to be deformed or cracked under the pressure, or the high-drawing screw may be in the cement mortar. Or loose displacement in the concrete, resulting in a serious lack of installation results of the steel vertical column.

Furthermore, the steel vertical column constructed and installed in the above-mentioned conventional manner, if the high-pull screw has been embedded in the cement mortar or concrete, it is found that the installation position of the high-pull screw has a large error, and it is necessary to knock It is time-consuming and labor-intensive to dismantle the cement mortar or concrete used to fix the high-drawing screw, and then perform correction positioning and re-grouting and solidification.

Therefore, it is necessary to provide a means or means for the steel vertical column to be easily and quickly completed on the construction site, and the installation position of the steel vertical column can be adjusted after installation.

The present invention depicts a steel erect column concrete pedestal for mounting a steel erect column having a bottom end plate at the bottom end, wherein the bottom end plate is formed with at least four through mounting holes. The cast concrete base comprises: a flat concrete base, an upright concrete pier, and at least four upright high pull screws; characterized in that: the flat concrete The base, the upright concrete pier and the at least four upright high-slapping screws are integrally formed to form a transportable unit; wherein the upright concrete pier is integrally formed on a central portion of the flat concrete base, and the upright concrete The pier column has an upright column body and a top horizontal surface; the four upright high tension screw systems are embedded in the upright column of the upright concrete pier column and the flat concrete base, and extend upwardly and upwardly to protrude from the upright concrete pier column The top horizontal surface; the four upright high-drawing screws extending upwardly from the top horizontal surface of the upright concrete pier are spaced apart from each other so as to be able to penetrate through the bottom end plate of the steel vertical column A mounting hole is provided for mounting the steel upright column to the concrete base.

The crucible pedestal is formed by the crucible, and the steel erect column can be quickly and easily installed and fixed on the concrete pedestal on the site, and the steel erect column can be installed on the slab. After casting the concrete pedestal, the installation position of the steel erect column can still be adjusted.
