Problems solved by technology

When the concrete is poured, the anchor bolts are easy to shift and tilt under the interference of external force, which leads to the position deviation of the exposed screw on the top exceeding the specification requirements, which makes the installation of the steel structure column difficult and seriously affects the connection with the steel structure column. connection quality
Even if adjustments are made in the later stage, the bearing capacity requirements of the original design cannot be met, and the adjustment is time-consuming and laborious, which will also affect the construction period

Embodiment 1

[0068] A foundation prefabricated column such as figure 1 As shown, it includes a column body 1 and anchor bolts 2. The anchor bolts 2 are poured inside the column body 1, and include a vertically arranged rod part 21 and a leg 22 perpendicular to the rod part 21. The rod part 21 and the leg part 22 are integrated Formed structure, the upper end of the rod part 21 protrudes from the cylinder 1 and is placed above the cylinder 1, and the top part of the rod part 21 can be a bolt head. The rod portion 21 of the anchor bolt 2 protrudes downwards from the bottom surface of the column body 1 , and the leg 22 is located outside the column body 1 .

[0069] Such as figure 2 As shown, during installation, a cushion layer is poured at the bottom of the foundation pit 5 and a reinforcement mesh is arranged, and then the foundation prefabricated column is hoisted into the foundation pit 5. After adjusting the position and height, the feet 22 are connected and fixed with the reinforceme...

Embodiment 2

[0078] Reminisce figure 2 , the top of the foundation is threadedly connected with the steel plate 71 fixed on the bottom of the H-shaped steel 7 by the anchor bolt 2 to achieve the purpose of fixing the H-shaped steel 7. Because the anchor bolt 2 is prone to breakage under the condition of bearing a large shear stress, so if Figure 7 As shown, the lower end of the steel plate 71 fixed with the H-shaped steel 7 is welded with a shear pile 72 , and the shear pile 72 is arranged perpendicular to the steel plate 71 . In the prior art, when the foundation is poured, a mold will be placed at the center of the upper end to pour out the positioning holes 4 corresponding to the shear piles 72. When the H-shaped steel 7 is installed, the shear piles 72 will be inserted into the positioning holes 4, and finally the steel plate Concrete is poured in the gap between 71 and the foundation and in the positioning hole 4 to achieve the purpose of bearing shear stress.

[0079] Such as F...

Embodiment 3

[0083] The difference from Example 1 is that, if Figure 12 and Figure 13 As shown, it also includes a prefabricated ground beam 8 arranged on the side of the column body 1, and the prefabricated ground beam 8 connects two adjacent foundation prefabricated columns. The prefabricated ground beams 8 are pre-embedded with ground beam connecting ribs 81 in the horizontal direction, and the ground beam connecting ribs 81 are connected with the foundation prefabricated columns. A foundation post-cast belt is set between the end of the prefabricated ground beam 8 and the column body 1, and after the concrete is poured, the prefabricated ground beam 8 is connected to the foundation as a whole.

[0084] The ground beam connecting bars 81 and the column connecting bars 11 can be connected by conventional fixed connection methods such as binding connection, welding, straight thread sleeve 101 connection and the like.

[0085] Such as Figure 14 As shown, the end of the ground beam co...

Abstract

The invention discloses a foundation prefabricated column, characterized by comprising a column body and a foundation bolt, wherein the foundation bolt is vertically cast in the column body, and the foundation bolt comprises a rod part and a leg perpendicular to the rod part and integrally formed with the rod part; the upper part of the rod part extends out of the column body and is disposed abovethe column body; the invention also discloses an installation method of the foundation prefabricated column, and the installation method is characterized by comprising the following installation steps of step a, digging a foundation pit, pouring a concrete cushion layer at the bottom of the foundation pit and arranging a steel mesh on the cushion layer; step b, placing the foundation prefabricated column vertically in the foundation pit; step c, adjusting the position of the foundation prefabricated column to keep the rod part of the foundation bolt vertical; step d, pouring concrete at the bottom of the foundation pit, so that the concrete wraps the lower part of a main body; step e, backfilling the foundation pit after the concrete at the bottom of the foundation pit is solidified; theposition deviation of the foundation bolt in a foundation pouring process is avoided.

Description

technical field [0001] The invention relates to a building foundation, in particular to a foundation prefabricated column and its connecting structure and construction method. Background technique [0002] The foundation is the structural component that transfers the various actions the structure bears to the foundation. When the top of the foundation is connected to the steel structure column, it is necessary to pre-embed the anchor bolts in the foundation. In the common foundation construction process, it is necessary to vertically fix the anchor bolts in the foundation pit first, then bind the foundation steel bars, install the formwork, and finally pour concrete. When the concrete is poured, the anchor bolts are easy to shift and tilt under the interference of external force, which leads to the position deviation of the exposed screw on the top exceeding the specification requirements, which makes the installation of the steel structure column difficult and seriously af...
