[0002] The steel pipe concrete structure is a composite building structure composed of steel pipes and concrete, which improves the overall bearing performance through the synergistic effect of the two materials. The core mechanism lies in the fact that the steel pipe forms a tight hoop effect on the core concrete, which increases the compressive strength of the concrete to 2-3 times that of the ordinary state. At the same time, the deformation of the steel pipe buckling is effectively inhibited by the concrete filling. It is widely used in industrial plants, super high-rise buildings and bridge engineering. In order to ensure the performance of the steel pipe concrete frame, the performance test verification device for the steel pipe concrete frame is an important building construction performance test verification device. In the existing performance test verification device for the steel pipe concrete frame, there is no performance test verification device for the steel pipe concrete frame, and the press is still used to test the pressure of the steel pipe concrete frame. The pressure area between the press and the steel pipe concrete frame is limited, thereby affecting the performance test verification effect of the steel pipe concrete frame. The present application effectively explores and researches the technical problems of using a press to test the pressure of the steel pipe concrete frame through the technical feature that the performance test verification state of the steel pipe concrete frame is in a double-distributed pressure surface body clamping.

Furthermore, the platform, vertical frame, through beam, pressure seat, vertical beam, and pressure cylinder components, along with a vibration component, are arranged in a manner that applies vibration to the plate surface.

[0047] This invention designs a system in which two vertical frames are positioned between the pedestal and the through beam; a vertical beam, a pressure cylinder component, and a vibration component form a set of beam-cylinder moving components; multiple sets of beam-cylinder moving components are positioned between the through beam and the pedestal; an extended support frame and a blower form a set of frame components; two pressure seats and multiple sets of frame components are respectively positioned on the through beam; multiple pressure sensors are positioned between the mounting plate and the pedestal; multiple displacement sensors are positioned between the vertical frames and the steel-concrete composite frame; beam section III and rod section are configured to connect with beam section II; the through hole body of the frame section, screw section I, receiving hole body II, and through hole body of the plate section are respectively configured to connect with rope section; the annular groove body of the frame section and screw section II are respectively configured to connect with receiving hole body III; the nut section and telescopic cylinder section are respectively configured to connect with beam section I; the moving seat section is configured to connect with receiving groove; and beam section I is configured to connect with seat section.

[0048] This invention designs a method for performance testing and verification of steel-concrete composite frames. The steps are as follows: the seat beam component realizes the three-dimensional spatial support and installation of the pressure-applying seat and the pressure-applying cylinder component; the pressure-applying cylinder component realizes the tensile loading pressure on the pressure-applying seat; and the pressure-applying seat realizes the plate-surface contact between the test sample section of the steel-concrete composite frame and the plate surface, so that the test and verification state of the compressive strength performance of the steel-concrete composite frame is in the clamping of the double-distributed pressure surface.

[0049] The technical effect of the above technical solution is that it highlights the technical feature that the test verification state of the compressive strength performance of the steel tube concrete frame is in the clamping of the double-distributed pressure surface, and introduces its application in the technical field of performance test verification methods for steel tube concrete frames.

[0050] The present invention comprises the following steps: When it is necessary to test and verify the performance of a steel-concrete composite frame, one end of the rope is placed into the through hole of the plate, and the other end of the rope is connected by a wire rope hook. The lug part I is connected to the lifting hook. The beam part II is lifted by lifting machinery, and the test sample section of the steel-concrete composite frame is placed on the upper end face of the mounting plate. The beam part II is lowered by lifting machinery, so that the plate is placed on the test sample section of the steel-concrete composite frame, and the outer side of the lower end face of the beam part II is separated from the horizontal part located at the upper end of the vertical frame. The lug part I is then separated from the lifting hook. Connect one end of the displacement sensor to the test sample section of the steel-concrete composite frame to establish the initial state signal. Install the strain gauge sensor on the detection point of the test sample section of the steel-concrete composite frame, thus placing the test sample section of the steel-concrete composite frame in the test verification state. When it is necessary to test and verify the wind load resistance performance of the steel-concrete composite frame, rotate the screw part III in the threaded hole of the beam part III, move the collar part on the outer end of the blower housing, and rotate the pin on the blower in the rotating hole of the ear seat II. The hairdryer's swing angle is adjusted to align its nozzle with the test section of the steel-concrete composite frame, putting the hairdryer in operation. The powerful airflow generated by the hairdryer acts on the test section of the steel-concrete composite frame. Wind load resistance parameters of the steel-concrete composite frame are obtained using the hairdryer's powerful airflow parameters, strain gauge sensors, and displacement sensors. After verifying the wind load resistance of the steel-concrete composite frame, the hairdryer is deactivated. When it is necessary to verify the compressive strength of the steel-concrete composite frame, the expansion joint is activated. With the cylinder in a retracted state, one end of the rope is placed into the through-hole of the frame, the receiving hole II, and the through-hole of the movable seat. The rope end is then connected via a wire rope hook, causing the telescopic cylinder to extend. This moves the lower horizontal part of the movable seat outward within the receiving groove, tautning the rope and causing the plate to move downward. This causes the end of beam II to move downward within the upper end of the vertical frame, applying a pressure load to the test sample section of the steel-concrete composite frame through the plate. The pressure value is monitored by the telescopic cylinder, a pressure sensor, and a strain gauge sensor. The load-bearing capacity parameters of the steel-concrete composite frame are obtained using displacement sensors. After the load-bearing capacity of the steel-concrete composite frame is tested and verified, the telescopic cylinder stops its extension movement. When it is necessary to test and verify the vibration resistance of the steel-concrete composite frame, the screw part I rotates in the receiving hole I, so that the inner end face of the screw part I acts on the rope part, and the rope part is fixedly installed in the receiving hole II. The nut part rotates in the screw part II, so that the inner end face of the nut part separates from the inner and outer end faces of the beam part I, and the screw part II moves in the receiving hole III.The inner wall of the through hole of the movable seat is brought into contact with the rope. The nut rotates in the opposite direction in screw part II, and the inner end face of the nut acts on the inner and outer end faces of beam part I, thus installing the vibrator on beam part I and putting the vibrator into working condition. The vibrating contact of the vibrator acts on the outer end of the horizontal part of the frame, causing the annular groove of the frame to move in the receiving hole III. The frame generates a vibration force on the rope, which, through the plate, puts the test sample section of the steel-concrete composite frame into a vibrating state. The vibration parameters of the vibrator, strain gauge sensors, and displacement sensors are used to obtain the vibration resistance performance parameters of the steel-concrete composite frame. After the vibration resistance performance of the steel-concrete composite frame is tested and verified, the vibrator is put into non-working condition, and screw part I rotates in the opposite direction in receiving hole I, separating the inner end face of screw part I from the rope. After verifying the performance of the steel-concrete composite frame through testing, one end of the displacement sensor was separated from the test sample section of the steel-concrete composite frame. The strain gauge sensor was removed from the detection area of ​​the test sample section of the steel-concrete composite frame. The telescopic cylinder was in a contracted state, and the rope was in a slack state. Using the wire rope hook, one end of the rope was separated. One end of the rope was removed from the through-hole of the frame, the receiving hole II, and the through-hole of the moving seat. The lug I was connected to the lifting hook. Using lifting machinery, beam II was lifted, separating the plate from the test sample section of the steel-concrete composite frame. The test sample section of the steel-concrete composite frame was removed from the upper end face of the mounting plate. Using lifting machinery, beam II was lowered, placing the outer side of the lower end face of beam II onto the horizontal section located at the upper end of the vertical frame. The lug I was then separated from the lifting hook.

[0051] The technical effect of the above solution is that it enables the operation of double-plate pressing and whole-plate support for the test sample section of the steel-concrete composite frame.

[0052] In this technical solution, the pressure seat and pressure cylinder components are basic components and essential technical features of the invention. The platform, vertical frame, through beam, vertical beam, vibration component, extended support frame, blower, pressure sensor, mounting plate, and displacement sensor are functional components, features that achieve other technical effects of the invention. The design of these technical features, such as the seat, strip, receiving groove, beam I, screw I, receiving hole I, receiving hole II, receiving hole III, beam II, ear seat I, plate, rod, rope, telescopic cylinder, moving seat, vibration component, frame, screw II, nut, part III, ear seat II, collar, and screw III, are technical features that comply with the Patent Law and its implementing regulations.

[0053] In this technical solution, the test verification state of the compressive strength of the steel tube concrete frame is achieved by the seat beam component and the pressure-applying seat, which are in the state of being clamped by a double-distributed pressure surface.

[0054] In this technical solution, the key technical features are the seat beam component, the pressure seat, and the pressure cylinder component, which are clamped in a double-distributed pressure surface, and the test verification state of the compressive strength performance of the steel-concrete composite frame.

[0102] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0103] A method for performance testing and verification of a steel-concrete composite frame includes the following steps: When it is necessary to test and verify the performance of the steel-concrete composite frame, one end of the rope 61 is placed into the through hole of the plate 41, and the other end of the rope 61 is connected by a wire rope hook. The lug part I 32 is connected to the lifting hook. The beam part II 31 is lifted by a lifting machine, and the test sample section of the steel-concrete composite frame is placed on the upper end face of the mounting plate 92. The beam part II 31 is lowered by the lifting machine, so that the plate 41 is placed on the test sample section of the steel-concrete composite frame, and the outer side of the lower end face of the beam part II 31 is separated from the horizontal part located at the upper end of the vertical frame 2. The lug part I 32 is then separated from the lifting hook. Connect one end of the displacement sensor 93 to the test sample section of the steel-concrete composite frame to set the displacement sensor 93 to its initial state signal. Install the strain gauge sensor on the detection point of the test sample section of the steel-concrete composite frame, thereby putting the test sample section of the steel-concrete composite frame into the test verification state. When it is necessary to test and verify the wind load resistance performance of the steel-concrete composite frame, the screw part III 84 is rotated in the threaded hole of the beam part III 81, the collar part 83 is moved on the outer end of the blower 9 housing, and the pin on the blower 9 is rotated in the rotating hole of the lug II 82. The swing angle of the blower 9 is adjusted so that the air outlet of the blower 9 corresponds to the test sample section of the steel-concrete composite frame, putting the blower 9 into working condition. The strong airflow generated by the blower 9 acts on the test sample section of the steel-concrete composite frame. The wind load resistance performance parameters of the steel-concrete composite frame are obtained through the strong airflow parameters of the blower 9, the strain gauge sensor, and the displacement sensor 93. After the test and verification of the wind load resistance performance of the steel-concrete composite frame is completed, the blower 9 is put into non-working condition. When it is necessary to test and verify the compressive strength performance of the steel-concrete composite frame, the telescopic cylinder 62 is in a retracted state. One end of the rope 61 is placed into the through-hole of the frame 72, the receiving hole II 54, and the through-hole of the moving seat 63. The rope 61 is then connected by a wire rope hook, causing the telescopic cylinder 62 to extend. This causes the lower horizontal part of the moving seat 63 to move outward in the receiving groove 13, tautning the rope 61. This causes the plate 41 to move downward, and the end of the beam II 31 to move downward in the upper port of the vertical frame 2. The plate 41 applies a pressure load to the test sample section of the steel-concrete composite frame. The compressive strength performance parameters of the steel-concrete composite frame are obtained through the driving pressure value of the telescopic cylinder 62, the pressure sensor 91, the strain sensor, and the displacement sensor 93. After the test and verification of the compressive strength performance of the steel-concrete composite frame is completed, the telescopic cylinder 62 is stopped from extending. When it is necessary to test and verify the vibration resistance performance of the steel-concrete composite frame, the screw part I 52 is rotated in the receiving hole I 53, so that the inner end face of the screw part I 52 acts on the rope part 61, and the rope part 61 is fixedly installed in the receiving hole II 54. The nut part 74 is rotated in the screw part II 73, so that the inner end face of the nut part 74 separates from the inner and outer end faces of the beam part I 51. The screw part II 73 is moved in the receiving hole III 55, so that the inner wall of the through hole of the moving seat part 63 contacts the rope part 61. The nut part 74 is rotated in the opposite direction in the screw part II 73, so that the inner end face of the nut part 74 acts on the inner and outer end faces of the beam part I 51, thereby installing the vibrating part 71 on the beam part I 51. The vibrating section 71 is put into operation, and its vibrating contact acts on the outer end of the horizontal section of the frame section 72, causing the annular groove of the frame section 72 to move within the receiving hole Ⅲ55. The frame section 72 generates a vibrational force on the rope section 61, which, through the plate section 41, puts the test sample section of the steel-concrete composite frame into a vibrating state. The vibration parameters of the vibrating section 71, strain gauge sensors, and displacement sensors 93 are used to obtain the vibration resistance performance parameters of the steel-concrete composite frame. After the vibration resistance performance of the steel-concrete composite frame is tested and verified, the vibrating section 71 is put into a non-operating state, and the screw section Ⅰ52 rotates in the opposite direction within the receiving hole Ⅰ53, separating the inner end face of the screw section Ⅰ52 from the rope section 61. After the performance of the steel-concrete composite frame is tested and verified, one end of the displacement sensor 93 is separated from the test sample section of the steel-concrete composite frame. The strain gauge sensor is removed from the detection area of ​​the test sample section of the steel-concrete composite frame. The telescopic cylinder 62 is in a contracted state, and the rope 61 is in a relaxed state. The other end of the rope 61 is separated through the wire rope hook. One end of the rope 61 is removed from the through hole of the frame 72, the receiving hole II 54, and the through hole of the moving seat 63. The lug I 32 is connected to the lifting hook. The beam II 31 is lifted by the lifting machinery, separating the plate 41 from the test sample section of the steel-concrete composite frame. The test sample section of the steel-concrete composite frame is removed from the upper end face of the mounting plate 92. The beam II 31 is lowered by the lifting machinery, placing the outer side of the lower end face of the beam II 31 onto the horizontal part located at the upper end of the vertical frame 2. The lug I 32 is separated from the lifting hook.

[0104] In verifying this invention, the inventors abandoned the existing technical feature of using a press to pressure test the steel-concrete composite frame. Instead, they first proposed a technical feature where the test verification of the steel-concrete composite frame's compressive strength is performed under the clamping of a dual-distributed pressure surface. This resulted in the first unexpected technical effect: the distributed application of pressure loads to the steel-concrete composite frame improved the accuracy of the performance test verification. The second unexpected technical effect: the application of pressure loads to the steel-concrete composite frame via the mounting plate 92, pressure seat 4, and pressure cylinder component 6 improved the uniformity of pressure load application. The third unexpected technical effect: the connection and installation of the mounting plate 92 and pressure seat 4 via the platform 1, vertical frame 2, through beam 3, pressure seat 4, and vertical beam 5 improved the support stability of the mounting plate 92. Yes, it satisfies the travel of the pressure seat 4, resulting in the fourth unexpected technical effect: it enables the application of vibration load to the steel-concrete composite frame through the vibration component 7, and strengthens the vibration parameters of the steel-concrete composite frame through the vibration motor, resulting in the fifth unexpected technical effect: it enables the application of wind load to the steel-concrete composite frame through the blower 9 and pressure sensor 91, satisfying the requirement of applying wind load at multiple points on the steel-concrete composite frame, resulting in the sixth unexpected technical effect: it enables the acquisition of test verification parameter signals through strain gauge sensor, pressure sensor 91 and displacement sensor 93, improving the accuracy of performance test verification of the steel-concrete composite frame, resulting in the seventh unexpected technical effect: it eliminates the need to use a press to test the pressure of the steel-concrete composite frame, and allows for accurate simulation test verification of the steel-concrete composite frame's usage scenarios.

[0105] In the second embodiment of the present invention, the seat beam component, the pressure seat 4, and the pressure cylinder component 6 are interconnected in a manner that verifies the compressive strength performance of the steel-concrete composite frame under the condition of being clamped by a double-distributed pressure surface.

[0106] In this embodiment, the pressure seat 4 is connected to the seat beam component and the pressure cylinder component 6 in a manner that allows for surface-to-surface contact between the test sample section of the steel-concrete composite frame.

[0111] The second embodiment of the present invention is based on the first embodiment. In the second embodiment of the present invention, the steps are as follows: the seat beam component provides three-dimensional spatial support for the pressure-applying seat 4 and the pressure-applying cylinder component 6; the pressure-applying cylinder component 6 applies tensile loading pressure to the pressure-applying seat 4; and the pressure-applying seat 4 achieves plate-to-plate contact with the test sample section of the steel-concrete composite frame. This ensures that the test verification of the compressive strength performance of the steel-concrete composite frame is performed under dual-distributed pressure surface clamping. The second embodiment of the present invention is based on the first embodiment. This invention has the following characteristics: 1. Due to the design of the seat beam component, pressure seat 4, and pressure cylinder component 6, the seat beam component enables three-dimensional spatial support and installation of the pressure seat 4 and pressure cylinder component 6. The pressure cylinder component 6 enables the application of tensile loading pressure to the pressure seat 4. The pressure seat 4 enables plate-to-plate contact between the test sample section of the steel-concrete composite frame and the plate surface. This allows the test verification of the compressive strength performance of the steel-concrete composite frame to be performed in a double-distributed pressure surface clamping state, solving the technical problem of using a press to test the pressure of the steel-concrete composite frame. Therefore, the performance test verification effect of the steel-concrete composite frame is improved.

[0114] 4. Due to the design of the vibration component 7, vibration loads can be applied to the steel-concrete composite frame.

[0115] 5. Due to the design of the extended support frame 8 and the blower 9, wind loads can be applied to the steel-concrete composite frame.

[0116] 6. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of this numerical range has achieved very good technical effect.
