DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0033] like Figure 1-14 As shown, the present invention provides a multi-story steel and concrete composite structure, including a steel plate frame composed of two correspondingly arranged front and rear end steel plates 2, two correspondingly arranged left and right side steel plates 3, and a bottom steel plate at the bottom. Concrete is poured into the interior of the steel plate frame, and a functional frame 4 is placed inside the steel plate frame, and a plurality of vertically arranged load-bearing frames 5 are placed inside the functional frame 4; wherein the functional frame 4 is composed of two longitudinally arranged transverse steel bars 9 and two longitudinally arranged transverse steel bars 10 in a transverse row, and the corresponding transverse steel bars 9 are fixedly connected to the longitudinal steel bars 10; each load-bearing frame 5 is respectively composed of a plurality of longitudinally arranged load-bearing steel bars 6, and a plurality of longitudinally arranged reinforcement frames 7 are fixedly connected to the inner sides of the load-bearing steel bars 6, and a cross-arranged pressure steel bar 8 is fixedly connected to the inner sides of the reinforcement frames 7.

[0034] The assembled steel plate frame can effectively shape the internal concrete, so that the concrete and the internal functional frame 4 and the load-bearing frame 5 are fused and solidified. When pouring concrete, in order to improve the compactness of concrete pouring and discharge the air inside the concrete, the functional frame 4 can be vibrated by knocking when pouring concrete. When the functional frame 4 vibrates, the vibration force can be transmitted to the inside of the steel plate frame through the longitudinal steel bars 10 and the transverse steel bars 9, so as to quickly and effectively vibrate the concrete, discharge the air in the concrete, and improve the compactness of concrete pouring. Under the action of the steel plate frame, the concrete will apply pressure to the inside when solidifying, and the concrete and the load-bearing frame 5 are solidified into one. The bearing capacity of the concrete is improved by the load-bearing frame 5, and the cross-arranged pressure steel bars 8 can withstand the pressure of the concrete from all directions, thereby improving the toughness and firmness of the concrete after solidification.

[0035] A plurality of longitudinally arranged reinforcing ribs 11 are fixedly connected between the two correspondingly arranged longitudinal steel bars 10 at the front and rear sides, and the reinforcing ribs 11 transmit the vibration force between the longitudinal steel bars 10 at the front and rear sides. The reinforcing ribs 11, the transverse steel bars 9 and the longitudinal steel bars 10 are hollow structures that penetrate each other. When the functional frame 4 is knocked, the vibration force can be transmitted on the surface of the reinforcing ribs 11, the transverse steel bars 9 and the longitudinal steel bars 10 and transmitted through the internal air. The vibration transmission effect is better, so that the functional frame 4 can vibrate the concrete more effectively, fully improving the effect of vibrating the concrete, and the hollow structure adopted helps to reduce the weight of the functional frame 4, making it convenient for users to place and use it.

[0036] The surfaces of the end steel plate 2 and the side steel plate 3 are respectively fixedly connected with a plurality of crisscross reinforcing ribs 12, which are used to improve the rigidity of the end steel plate 2 and the side steel plate 3, increase the bearing capacity of the end steel plate 2 and the side steel plate 3, increase the effect of shaping the concrete, and improve the service life.

The setting of the fixing plate 17 can prevent the fixing rod 16 from disengaging, and the fixing knob 19 is screwed to the fixing rod 16 by rotating the fixing plate 17. The fixed knob 19 can drive the fixing rod 16 to move, and increase the pre-stressing force between the end steel plate 2 and the side steel plate 3 and the concrete under the dual pressure of the fixing plate 17 and the fixing knob 19. The corresponding end parts of the side steel plate 3 and the end steel plate 2 are respectively fixedly connected with sealing gaskets, which can not only improve the tightness of the docking between the side steel plate 3 and the end steel plate 2 bracket, but also can make the side steel plate 3 and the end steel plate 2 have a displacement distance to apply pressure to the inside of the concrete when the fixing knob 19 is grasped. The pre-stressing force can continuously pressurize the concrete inward when the concrete solidifies, thereby avoiding the concrete shrinking inward after solidification to cause gaps between the concrete and the side steel plate 3 and the end steel plate 2, thereby further improving the quality of the concrete after solidification.

The upper ends of the connecting sliders 24 are respectively fixedly connected to auxiliary plates 26, which are respectively located on the outer sides of the mounting plate 18. The meshing of the ratchet blocks 23 and the ratchet plates 22 can facilitate the installation of the fixing rod 16. When fixing the rod 16, one end of the fixing rod 16 is inserted into the mounting hole on the surface of the mounting plate 18, and the fixing rod 16 can be inserted in one direction but cannot be moved out by the engagement of the ratchet block 23 and the ratchet bar, so that the corresponding end steel plate 2 and the corresponding side steel plate 3 can be quickly assembled, and when the fixing knob 19 is turned to increase the pre-stressing force, the pre-stressing force applied can only act on the concrete on the inside under the action of the ratchet block 23 and the ratchet bar, and will not be rebounded by external factors such as vibration and consume the pre-stressing force, thereby improving the shaping effect of the concrete; the auxiliary plate 26 is used to facilitate the user to drive the ratchet block 23 to engage with the ratchet bar, which is convenient for disassembling the fixing rod 16. The user can push the auxiliary plate 26 outward to drive the ratchet block 23 to move outward, and compress the engagement spring 25 under the extrusion of the connecting slider 24. After loosening the auxiliary plate 26, the ratchet block 23 can be pushed to engage with the ratchet bar again under the push of the engagement spring 25, which is convenient for the user to use.

When the side steel plate 3 and the end steel plate 2 are respectively connected to the bottom steel plate 1, the triangular support 13 can provide a supporting effect, and the firmness of the installation is increased by sliding cooperation between the connecting slider 24 and the connecting slide groove.
