The steel column positioning device can be used for accurately positioning the steel column.

Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a cup-mouth foundation steel column positioning device. Background Art

[0002] The cup-shaped foundation is a form of independent foundation. A cup-shaped opening is opened on the top of the concrete foundation for installing prefabricated column components. After the column is installed, fine stone concrete is poured to connect the cup-shaped foundation and the column. During the on-site construction process, the steel column installation deviation and the substandard verticality of the steel column can easily lead to insufficient thickness of the steel column concrete protective layer, cracking at the column root, and poor column forming quality, which will seriously affect the safety and stability of the frame structure. Therefore, it is necessary to accurately position the steel column on the cup-shaped foundation. The traditional positioning method is to weld steel bars for positioning and workers manually operate the installation and placement, which has poor accuracy. Summary of the invention

[0003] The utility model aims to overcome the defects in the prior art and provide a cup mouth base steel column positioning device.

[0004] The technical solution adopted by the utility model is as follows: a cup-mouth foundation steel column positioning device, characterized in that it is composed of two parallel fixing bars and two parallel connecting bars, the thickness of the fixing bars is greater than the connecting bars; the fixing bars and the connecting bars each have a plurality of vertical pin holes, each fixing bar and each connecting bar are connected with pins to form a quadrilateral; the outer side of the connecting bar has at least one fixing rod parallel to the connecting bar, and the fixing rod is connected and fixed to the two fixing bars.

[0005] The fixing bar is also provided with screw holes in the horizontal direction, and the fixing rod is passed through the screw holes of the two fixing bars; the outer side of the screw hole is connected with a bolt through a thread, and the tail of the bolt is a sheet-shaped object.

[0006] In the utility model, there is a quadrilateral composed of a fixing strip and a connecting strip, and the direction toward the inside of the quadrilateral is called inside, and the opposite direction is called outside.

[0007] Since the quadrilateral has unstable characteristics, the utility model is equipped with a fixing rod, so that the fixing strip and the connecting strip can form a stable rectangle. By selecting different screw holes for connection and assembly, the internal size of the rectangle can be adjusted to adapt to the size requirements of the steel column section; the cross section of the cup mouth foundation itself is also a rectangle, with two dimensions of length and width. By selecting and cutting the length of the fixing strip, one of the dimensions can be met, and the other dimension can be met by adjusting the bolt so that the tail sheet hits the inner wall of the cup mouth foundation, so that the utility model can also adapt to the cross-sectional size of the cup mouth foundation.

[0008] It can be seen that the steel column can be accurately positioned by using the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the utility model.

[0010] Figure 2 It is an application schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] See the attached drawings. The utility model includes a thicker fixing strip 1 and a thinner connecting strip 2, each with a plurality of pin holes 4. Four pins 5 pass through the pin holes to connect the fixing strips and the connecting strips in pairs to form a rectangle. There is also a fixing rod 3 on the outside of the two connecting strips, which is parallel to the connecting strips and is also connected to the two fixing strips 1. The extension lines of the two ends of the fixing rod 3 are respectively provided with bolts 6, the head of the bolt 6 is threadedly connected to the fixing strip, and the tail is a sheet-shaped fixing sheet 7.

[0012] In the embodiment, the upper radius of the pin is 20mm and the height is 15mm, the lower end radius is 1mm and the height is 10mm, the connecting bar is 50mm wide and 10mm thick, the connecting bar mounting hole is an opening with a radius of 20mm every 100mm, the fixing bar is 60mm wide and 30mm thick, the fixing hole of the fixing bar is a pit with a radius of 20mm and a depth of 5mm set every 100mm, and a pit with a radius of 1mm and a depth of 10mm is set in the center of the pit, the fixing rod is an M10 screw, and the size of the fixing plate is 10mmX10mmX4mm.

[0013] When in use, the cup mouth foundation 10 has been laid, with a specific rectangular cross-section; assemble the utility model as described in the previous paragraph, cut a fixing strip that matches the length of the cup mouth foundation, connect the two fixing strips with a connecting strip, and select a suitable pin hole position according to the designed cross-sectional size of the steel column, so that the rectangle formed after the fixing strip and the connecting strip are assembled matches the cross-section of the steel column 20; adjust the bolt 6, so that the fixing plate 7 is in contact with the width direction of the cup mouth foundation, and then install the steel column 20.
