Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a rigid column-type steel frame splicing structure. Background Art

[0002] The rigid column is a steel rigid column, which uses the internal structure of the steel as a supporting force frame, welds bolts on the outer surface, ties the steel bars and pours concrete to form a tightly integrated structure. The steel rigid concrete structure has the advantages of high strength, small cross-sectional dimensions of the components, strong bond strength with concrete, space saving, reduced cost, improved engineering quality, and significantly improved seismic performance of the structure. It is currently widely used in super-high-rise buildings and buildings with seismic requirements.

[0003] Steel rigid columns are generally set in the core tube of a single building. To meet the requirements of earthquake-resistant design, they all run through the top of the structure. Considering the hoisting conditions of the steel structure construction on site, the steel frame is processed and hoisted in sections, assembled and welded section by section to meet the mechanical lifting and step-by-step layered construction of the main structure.

[0004] The installation accuracy of the upper and lower sections of the steel skeleton directly affects the quality and safety of the upper building structure. Generally, before the upper and lower sections of the steel skeleton are welded and connected on site, it is necessary to use a measuring instrument to detect the verticality and correct the tilt state; in the prior art, such as Chinese patent CN106150105A, a method for installing a rigid column is disclosed, in which an adjustment plate is welded on the outer wall of the upper and lower sections of the steel skeleton, and a jack is placed between the upper and lower adjustment plates. By operating the jacks on each side to lift, the vertical state of the upper section of the steel skeleton is adjusted to achieve tilt correction.

[0005] This operation plan requires the use of multiple jacks for operation, which need to be dismantled after use, and the operation is cumbersome. Moreover, during the actual correction operation, due to the large dead weight of the steel frame itself, it is difficult to accurately push the jack back a small amount, making the operation difficult.

[0024] See also Figures 1 to 5 A rigid column steel frame splicing structure comprises a lower steel frame 2 fixed on a foundation plane 6 and an upper steel frame 1 installed above the lower steel frame 2. An installation groove is provided on the top of the lower steel frame 2, and a correction connection component 3 is arranged in the installation groove; the upper steel frame 1 is fixedly connected to the lower steel frame 2 after correction positioning by the correction connection component 3.

[0027] Furthermore, threaded holes are provided on the bottom surfaces of the four directions of the cross positioning groove 311 located at the top longitudinally, and the adjusting screws 320 are respectively screwed inside the threaded holes, and the screw ends of the adjusting screws 320 face the inside of the cross positioning groove 311 .

[0028] Furthermore, a nut seat 312 is fixedly provided on the cross base 313 for threadedly connecting the double-headed screw 330 .

[0029] Furthermore, the upper section steel frame 1 and the lower section steel frame 2 are both cross-shaped steels, and the ends of the cross-shaped steels are also provided with side panels, and bolts 4 are evenly provided on the outer walls of the side panels.

[0030] Furthermore, longitudinal steel bars 5 are distributed circumferentially around the outer periphery of the upper section steel frame 1 and the lower section steel frame 2, and concrete is poured around the upper section steel frame 1, the lower section steel frame 2 and the longitudinal steel bars 5 to form a rigid column.

[0031] The working principle of this utility model:

[0032] In the utility model, the rigid steel column is formed by adding a steel frame in the middle of the vertical steel bars of the conventional reinforced concrete column, and welding nails on the periphery of the steel frame to increase the bond strength between the steel column and concrete to form a vertical member that bears the force together. The steel column with a rigid column steel core is called a rigid steel column, i.e., a steel frame. The first section of the steel column that is first hoisted and fixed on the foundation plane is the first section of the rigid steel column, i.e., the lower section of the steel frame 2. The structure comprises a lower section of the steel frame 2 fixed on the foundation plane 6 and an upper section of the steel frame 1 installed above the lower section of the steel frame 2. A mounting groove is provided on the top of the lower section of the steel frame 2, in which a deviation correction connection component 3 is arranged. The upper section of the steel frame 1 is fixedly connected to the lower section of the steel frame 2 after being corrected and positioned by the deviation correction connection component 3. At the same time, longitudinal steel bars 5 are circumferentially distributed around the outer periphery of the upper section of the steel frame 1 and the lower section of the steel frame 2. Concrete is poured around the upper section of the steel frame 1, the lower section of the steel frame 2 and the longitudinal steel bars 5 to form a rigid column. The upper section of the steel frame 1 and the lower section of the steel frame 2 are both cross-shaped steels, and the ends of the cross-shaped steels also have side panels, and bolts 4 are evenly arranged on the outer walls of the side panels for fastening.

[0033] In this structure, in order to refine the verticality of the first frame, the height of the first frame is generally not set too high. Therefore, longitudinal steel bars 5 are distributed circumferentially around the outer periphery of the upper steel frame 1 and the lower steel frame 2, and concrete is poured around the upper steel frame 1, the lower steel frame 2 and the longitudinal steel bars 5 to form a rigid column.

[0034] According to the construction method of connecting the rigid columns section by section, the upper section of the steel frame 1 and the lower section of the steel frame 2 can be fixedly connected by welding; since the accuracy of the end face of the steel frame cannot be very accurately controlled during processing, and there are operational errors in the hoisting construction process, after the upper section of the steel frame is hoisted and connected with the lower section of the steel frame by a crane, it is necessary to consider the interference and adjust the inclination state of the upper section of the steel frame, so the upper section of the steel frame 1 and the lower section of the steel frame 2 are fixedly connected after the correction positioning of the correction connection component 3; therefore, an installation groove is opened on the top of the lower section of the steel frame 2, and the correction connection component 3 is arranged in the installation groove.

[0035] The deviation-correcting connection assembly 3 includes a double-headed screw 330 and a pair of positioning seats 310. The pair of positioning seats 310 are symmetrically arranged at the two ends of the double-headed screw 330, and the screw threads at the two ends of the double-headed screw 330 have opposite rotation directions. At the same time, an external hexagonal column is installed in the middle of the double-headed screw 330 for cooperating with a wrench to screw the double-headed screw 330. Since the screw threads at the two ends of the double-headed screw 330 have opposite rotation directions, when the external hexagonal column in the middle is rotated to control the rotation of the double-headed screw 330, the spacing between the upper and lower positioning seats 310 can be adjusted, and the entire upper section of the steel frame 1 can be lifted or lowered.

[0036] Among them, the positioning seat 310 includes a cross base 313, on which a cross positioning groove 311 is opened, and the cross positioning groove 311 is used to adapt to the upper section steel frame 1 and the lower section steel frame 2; the bottom surfaces of the four directions of the cross positioning groove 311 located at the top longitudinally are provided with threaded holes, and the insides of the threaded holes are respectively screwed with adjusting screws 320, and the screw ends of the adjusting screws 320 face the inside of the cross positioning groove 311. By rotating the adjusting screw 320, the length of its screw section extending into the cross positioning groove 311 can be adjusted, that is, the support height of the cross steel end face in the cross positioning groove 311 can be adjusted.

[0037] In actual work, when the upper section of the steel frame 1 is observed by external measuring instruments or deflected to one side, the adjusting screw 320 corresponding to this side is adjusted to lift upward, so as to fine-tune the upper section of the steel frame 1 to a perpendicular state with the foundation plane 6, and then the connection can be welded; in addition, since the cross-shaped steel end face used in the upper section of the steel frame 1 is embedded in the cross positioning groove 311 of the positioning seat 310 during installation, the correction connection assembly 3 has a correction effect on the upper section of the steel frame 1 and a positioning effect. When the upper section of the steel frame 1 is hoisted and slowly falls, it falls into the cross positioning groove 311, which can save the manual adjustment of the end face alignment, and the operation is more convenient.

[0038] It should be noted that during alignment and correction operations, the correction connection assembly 3 cannot be used as a complete load-bearing structure and requires lifting equipment to assist in lifting. After the correction positioning is completed, welding construction can be carried out at the connection, and the lifting equipment can be withdrawn after welding is completed.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
