Description

Technical Field

[0001] This utility model relates to the technical field of steel structures, and in particular to a steel structure footing. Background Technology

[0002] Steel structure engineering is becoming increasingly widespread. In the installation of the foundation of a steel structure, a column pier is usually set on the ground, and bolts are installed on the column pier. A flat steel plate is used as the foundation at the bottom of the steel column. The flat steel plate has through holes that are compatible with the bolts. After the bolts pass through the through holes, nuts are used to lock the flat steel plate to the column pier, thus completing the installation and fixing of the foundation of the steel structure.

[0003] However, during an earthquake, existing steel structure footings suffer severe deformation or even breakage under horizontal seismic forces. Therefore, it is necessary to design a steel structure footing with earthquake-resistant capabilities. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a steel structure anchor that can utilize the relative sliding between the base plate and the steel column to absorb the force of earthquakes, thereby improving the overall seismic resistance of the anchor.

[0005] A steel structure foot according to an embodiment of the present invention includes: a steel column with a foot formed at its bottom; a base plate with a supporting surface on its top surface for supporting the bottom of the steel column; a slot extending vertically through the base plate, through which the foot can pass; in the horizontal direction, the width of the slot is greater than the width of the foot, and the length of the slot is greater than the length of the foot; and a limiting structure including an upper limiting member and a lower limiting member disposed on the foot, the upper limiting member being located above the base plate, and the lower limiting member being located below the base plate, the upper limiting member and the lower limiting member abutting against the base plate vertically.

[0006] A steel structure foundation anchor according to an embodiment of the present utility model has at least the following beneficial effects:

[0007] This utility model, by setting up a steel column, a base plate, a slot, an upper limit member, and a lower limit member, addresses the installation of the foundation foot by inserting the steel column's prongs into the slot, allowing the upper limit member to abut against the top surface of the base plate for limitation. The lower limit member can be fixed to the prongs by welding, allowing it to abut against the bottom surface of the base plate for limitation. The upper and lower limit members abut against the base plate vertically, connecting the base plate and the steel column. The base plate is then fixed to the infrastructure, ensuring the steel column remains upright. Thus, the foundation foot structure is simple, has low manufacturing costs, and is easy to install. Functionally, the gap between the slot and the prongs allows the steel column to slide back and forth or left and right on the base plate in the horizontal direction during an earthquake, absorbing the seismic force and improving the overall earthquake resistance of the foundation foot, preventing deformation or breakage.

[0008] According to an embodiment of the present utility model, a steel structure foot is provided, wherein the steel column is an H-beam, the H-beam includes two vertical strips and an intermediate strip located between the two vertical strips, the intermediate strip connects the two vertical strips, and the bottom of the two vertical strips is respectively connected to the pin.

[0009] According to an embodiment of the present utility model, a steel structure foot is provided with two slots, which are arranged opposite to each other, and each slot allows a pin at the bottom of the upright strip to pass through.

[0010] According to an embodiment of the present utility model, the upper limit member is a first plate, which is located on the side of the insert near the middle strip, and the first plate connects the two vertical strips and the middle strip.

[0011] According to an embodiment of the present utility model, a steel structure foot is provided, wherein the lower limiting member is a second plate, and the second plate is connected to the pins at the bottom of the two upright plates.

[0023] The following describes a steel structure footing according to an embodiment of the present invention, with reference to the accompanying drawings.

[0024] Reference Figure 1 The present invention aims to provide an embodiment of a steel structure footing.

[0025] A steel structure footing according to an embodiment of this utility model, referring to... Figure 1 and Figure 2 The system includes a steel column 100, a base plate 120, a slot 130, and a limiting structure. The bottom of the steel column 100 has a pin 110. The top surface of the base plate 120 has a support surface for supporting the bottom of the steel column 100. The slot 130 is vertically disposed through the base plate 120, and the pin 110 can pass through the slot 130. In the horizontal direction, the width of the slot 130 is greater than the width of the pin 110, and the length of the slot 130 is greater than the length of the pin 110. The limiting structure includes an upper limit member 140 and a lower limit member 150 disposed on the pin 110. The upper limit member 140 is located above the base plate 120, and the lower limit member 150 is located below the base plate 120. The upper limit member 140 and the lower limit member 150 abut against the base plate 120 vertically.

[0026] In terms of installation, the pins 110 of the steel column 100 are passed through the slots 130, so that the upper limit member 140 abuts against the top surface of the base plate 120 for limitation. The lower limit member 150 can be fixed to the pins 110 by welding, so that the lower limit member 150 abuts against the bottom surface of the base plate 120 for limitation. The upper limit member 140 and the lower limit member 150 can abut against the base plate 120 from top to bottom, connecting the base plate 120 and the steel column 100. Then the base plate 120 is fixed to the infrastructure to ensure that the steel column 100 is in an upright state. Thus, the base structure is simple, the manufacturing cost is low, and the installation is convenient.

[0027] In terms of functionality, there is a gap between the slot 130 and the pin 110. In the event of an earthquake, the steel column 100 can slide back and forth or left and right on the base plate 120 in the horizontal direction to absorb the force of the earthquake, thereby improving the overall earthquake resistance of the base and preventing the base from deforming or breaking.

The intermediate strip 170 connects the two vertical strips 160, and the bottom of the two vertical strips 160 is respectively connected to a pin 110.

[0029] Understandably, H-beams are existing technology, readily available on the market, easy to manufacture, resulting in low production costs for foundations and improved production efficiency.

[0030] In addition, the H-beam is composed of a middle strip 170 and two vertical strips 160, which makes its structure stable, which helps to improve the strength of the steel column 100 and reduce the deformation of the steel column 100.

[0031] In some embodiments of this utility model, two slots 130 are provided, and the two slots 130 are arranged opposite to each other. Each of the two slots 130 allows a pin 110 at the bottom of a vertical plate to pass through.

[0032] Therefore, both slots 130 are fitted with pins 110, making the steel column 100 more stable when erected on the base plate 120 and improving the bending strength of the pins 110.

[0033] In some embodiments of this utility model, the upper limit member 140 is a first plate, which is located on the side of the pin 110 near the middle strip 170. The first plate connects the two vertical strips 160 and the middle strip 170.

[0034] Preferably, a first plate is used as the upper limit member 140. The first plate has a simple structure and is easy to manufacture. Furthermore, the first plate is fixed between the upright strip 160 and the intermediate strip 170, so that the first plate can firmly restrict the steel column 100 and ensure that the steel column 100 is in an upright state.

[0035] It should be noted that, depending on the design requirements, the shape of the upper limit component 140 can also be in other forms.

[0036] In some embodiments of this utility model, the lower limiting member 150 is a second plate, and the second plate is connected to the pins 110 at the bottom of the two vertical strips 160.

[0037] Preferably, a second plate is used as the lower limit member 150. The second plate has a simple structure and is easy to manufacture. Furthermore, the second plate is fixed between the two pins 110, so that the second plate can firmly restrict the steel column 100 and ensure that the steel column 100 is in an upright state.

[0038] It should be noted that, depending on the design requirements, the shape of the lower limit component 150 can also be in other forms.

[0039] In some embodiments of this utility model, reference is made to Figure 3 The substrate 120 is provided with a through hole 180, and a locking bolt 190 is provided in the through hole 180.

[0040] Therefore, during the installation of the base plate, the locking bolt 190 is inserted into the through hole 180, so that the locking bolt 190 and the nut fix the base plate 120 to the infrastructure.
