Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a stiffened box-shaped steel column. Background Art

[0002] As is well known, the construction method of crossing steel bars through a box-shaped steel column and a concrete structural beam is widely used in the construction of large factories, especially in factories with large live loads such as logistics and warehousing and public construction projects. In the process of traditional construction, holes are drilled in the steel column, and then the beam steel bars are installed one by one. The beam steel bars are welded through sleeves. The pre-welded sleeves are difficult to cope with the cumulative deviation within the allowable range that may occur during the on-site steel bar penetration. In addition, the on-site beam steel bars are often heavy. Since the sleeves are pre-welded, only the steel bars can be screwed for connection, and it is extremely difficult to construct the steel bars with an anchorage section. Moreover, the method of piercing holes one by one has extremely low fault tolerance, often resulting in re-milling holes on site, and the difficulty of continuously piercing holes on both sides of the box-shaped column is also extremely high. Content of the Utility Model

[0003] In order to overcome the deficiencies in the background art, the utility model discloses a stiffened box-shaped steel column. By providing a base and a reducing pipe on the lower column body, and arranging an upper column body on the reducing pipe, and studs are arranged on the lower column body and the reducing pipe, the purpose of reducing the construction difficulty, improving the work efficiency and construction quality is achieved.

[0004] In order to achieve the purpose of the utility model, the following technical scheme is adopted:

[0005] A stiffened box-shaped steel column includes a lower column body, a base, a reducing pipe, an upper column body and studs. A base is provided at the lower end of the lower column body, a reducing pipe is provided at the upper end of the lower column body, an upper column body is provided at the upper end of the reducing pipe, studs are distributed on the side surfaces of the lower column body and the reducing pipe, and inner perforations are distributed on the side surface at the upper end of the lower column body. The transverse beam steel bars pass through the corresponding inner perforations.

[0006] The upper surface of the base is connected to the lower surface of the lower column body, and the base is fixedly installed on the ground cement platform through bolts.

[0007] The lower column body is of a hollow rectangular structure, and studs are distributed at equal intervals on the side surface of the lower column body. The inner perforations on the opposite side surfaces of the lower column body are correspondingly arranged.

[0008] Reinforcing plates are distributed on the side surface of the lower column body, the reinforcing plates cover the inner perforations, and outer perforations are provided on each reinforcing plate. The outer perforations are correspondingly arranged and communicated with the adjacent inner perforations.

[0009] Limit wires are distributed in the outer perforations, the limit wires are arranged in a staggered manner, and the beam steel bars pass through the gaps between the limit wires.

[0010] Reinforcing ribs are distributed on the inner wall of the lower column body, and the reinforcing ribs are arranged in an equidistant array from top to bottom.

[0011] The reduced-diameter pipe is a hollow frustum-shaped structure. The lower surface of the reduced-diameter pipe is connected to the upper surface of the lower column body, and the area of the lower surface of the reduced-diameter pipe is smaller than that of the upper surface.

[0012] The upper column body is a hollow rectangular structure. The lower surface of the upper column body is connected to the upper surface of the reduced-diameter pipe, and ear plates are distributed on the side surface of the upper column body.

[0013] A stiffened box-shaped steel column according to the present utility model has strong practicability and is very convenient to use.

[0018] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model.

[0019] Combined with the attached Figures 1 to 3 A stiffened box-shaped steel column includes a lower column body 1, a base 2, a reduced-diameter pipe 3, an upper column body 4 and studs 5. A base 2 is provided at the lower end of the lower column body 1, a reduced-diameter pipe 3 is provided at the upper end of the lower column body 1, an upper column body 4 is provided at the upper end of the reduced-diameter pipe 3, studs 5 are distributed on the side surfaces of the lower column body 1 and the reduced-diameter pipe 3, and inner perforations 11 are distributed on the side surface at the upper end of the lower column body 1. The transverse beam steel bars pass through the corresponding inner perforations 11, avoiding drilling holes on both sides of the box-shaped column in the later stage, reducing the construction difficulty and improving the work efficiency and construction quality.

[0020] The upper surface of the base 2 is connected to the lower surface of the lower column body 1, and the base 2 is fixedly installed on the ground cement platform by bolts 6.

[0021] The lower column body 1 is of a hollow rectangular structure. Studs 5 are evenly distributed in an array on the side surface of the lower column body 1. The inner through holes 11 on the opposite side surfaces of the lower column body 1 are correspondingly arranged, and the transverse beam steel bars pass through the corresponding inner through holes 11.

[0022] Reinforcing plates 7 are distributed on the side surface of the lower column body 1. The reinforcing plates 7 cover the inner through holes 11. Outer through holes 8 are provided on each of the reinforcing plates 7. The outer through holes 8 are correspondingly arranged and communicated with the adjacent inner through holes 11. The reinforcing plates 7 enhance the structural strength at the joint of the lower column body 1 and the transverse beam steel bars.

[0023] Limit wires 12 are distributed in the outer through holes 8. The limit wires 12 are arranged in a staggered manner. The beam steel bars pass through the gaps between the limit wires 12, which facilitates the orderly arrangement of the beam steel bars and subsequent construction.

[0024] Reinforcing ribs 10 are distributed on the inner wall of the lower column body 1. The reinforcing ribs 10 are evenly distributed in an array from top to bottom, reducing the deformation of the lower column body 1 caused by the extrusion during concrete pouring.

[0025] The reducing pipe 3 is of a hollow frustum structure. The lower surface of the reducing pipe 3 is connected to the upper surface of the lower column body 1. The area of the lower surface of the reducing pipe 3 is smaller than that of the upper surface.

[0026] The upper column body 4 is of a hollow rectangular structure. The lower surface of the upper column body 4 is connected to the upper surface of the reducing pipe 3. Ear plates 9 are distributed on the side surface of the upper column body 4.

[0027] For the stiffened box-shaped steel column described in the embodiment, during use, first hoist the steel column onto the pre-set cement platform on the ground, and use bolts 6 to fix the base 2 on the cement platform. After fixation, install each beam steel bar on the lower column body 1 according to the design requirements. The transverse beam steel bars pass through the corresponding inner through holes 11 and through the gaps between the limit wires 12, which facilitates the orderly arrangement of the beam steel bars and subsequent construction, thus avoiding drilling holes on both sides of the box column later, reducing the construction difficulty, and improving the work efficiency and construction quality. After building a steel reinforcement cage and formwork around the steel column, concrete is poured. The reinforcing ribs 10 in the lower column body 1 reduce the deformation of the lower column body 1 caused by the extrusion during concrete pouring.
