Description

Technical Field

[0001] The present application relates to the field of steel structures, and in particular to a steel structure and concrete composite structure. Background Art

[0002] Steel-concrete composite structures are structures composed of steel and concrete or reinforced concrete components that work together as a whole, combining some of the characteristics of both steel and reinforced concrete structures. They can be used for floor beams, trusses, slabs, and columns in multi-story and high-rise buildings; roof panels, beams, and trusses in roof structures; columns and working platform beams and slabs in factories; and bridges. In China, they are also used for crane beams in factories. Steel-concrete composite structures fall into four categories: composite beams, composite slabs, composite trusses, and composite columns.

[0003] The combined structure of steel structure and concrete often fixes the steel structure in a casting mold and fixes the steel structure by a support frame or iron wire to ensure the stability and verticality of the steel structure when pouring concrete. However, the existing support frame is often fixed directly to the ground by bolts. When pouring concrete, as the weight of the concrete increases, the ground will deform to a certain extent, and the support frame will tilt or move. The use of binding materials such as iron wire to fix the steel structure will also result in the impact force during concrete pouring being greater than the strength of the iron wire, causing it to break, which will also affect the vertical stability of the steel structure. The inclination of the steel structure will change the stress state of the entire structure, resulting in a decrease in bearing capacity. In addition, the shaking of the steel structure during concrete pouring will cause quality problems such as voids and honeycombs during the concrete pouring process, thereby affecting the overall performance of the structure. In order to solve the above problems, a combined structure of steel structure and concrete is proposed.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] The embodiment of the present application discloses a steel structure and concrete combined structure. Figure 1-5A steel structure and concrete combination structure includes a base 1, a square frame 2 for pouring concrete is provided on the top of the base 1, a raft steel mesh 19 is fixed to the bottom of the square frame 2, corner reinforcement ribs 3 are provided at the four corners of the raft steel mesh 19, a steel cage 13 is provided in the middle section of the raft steel mesh 19, a clamping plate 12 for fixing the four corner reinforcement ribs 3 and a driving component for driving the clamping plate 12 to move simultaneously are provided in the square frame 2, when the driving component fixes the clamping plate 12 to the four corner reinforcement ribs 3, the driving component is also tangent to the surface of the outer ring steel bar of the steel cage 13;

[0025] It should be noted that the clamping plate 12 is arc-shaped, and the arc-shaped surface of the clamping plate 12 fits the outer surface of the corner reinforcement rib 3, which increases the friction between the clamping plate 12 and the corner reinforcement rib 3, making the clamping and fixing of the clamping plate 12 to the corner reinforcement rib 3 more stable;

[0026] By adopting the above technical solution, the base is pre-buried underground to reduce deformation caused by impact on the ground during concrete pouring, and the raft steel mesh 19 is fixed to the bottom of the square frame 2 so that the corner reinforcement 3 corresponds to the four corners of the square frame 2. The driving component is operated so that the clamping plate 12 clamps and fixes the corner reinforcement 3 while being tangent to the outer ring steel surface of the steel cage 13, ensuring the verticality of the corner reinforcement 3 and the stability of the raft steel mesh 19 during concrete pouring, while increasing the friction with the steel cage 13 and reducing the shaking of the steel cage 13 during concrete pouring.

[0027] Reference Figure 1 、 3 The driving assembly includes a bidirectional screw rod 5, a guide rod 6, a rocker 7, a movable plate 10, and a support rod 11. The bidirectional screw rod 5 rotates on the square frame 2, the guide rod 6 is fixed on the square frame 2, and there are two movable plates 10. The two movable plates 10 are threadedly connected to the bidirectional screw rod 5, one end of the rocker 7 is fixed to the bidirectional screw rod 5, and the two movable plates 10 are clearance-matched with the guide rod 6. One end of the support rod 11 is fixed to the side of the two movable plates 10 away from each other and the other end of the support rod 11 is respectively fixed to the outer surface of each splint 12. When the inner diameter of the splint 12 fits the outer diameter of the corner reinforcement 3, the side of the two movable plates 10 close to each other is tangent to the outer ring steel bar surface of the steel cage 13;

[0028] It should be noted that one section of the thread on the bidirectional screw rod 5 is a left-hand thread and the other section is a right-hand thread, and the two movable plates 10 are threadedly connected to the left-hand thread and the right-hand thread respectively;

[0029] By adopting the above technical solution, the bidirectional screw 5 is rotated by shaking the rocker 7, and the two movable plates 10 are simultaneously moved away from each other under the guidance of the guide rod 6. The movable plate 10 pushes the support rod 11 and the clamping plate 12 thereon to clamp and fix the corner reinforcement 3. At this time, the side of the two movable plates 10 that is close to each other is tangent to the surface of the outer ring of the steel cage 13, which increases the friction between the movable plate 10 and the steel cage 13 and reduces the shaking of the steel cage 13 during the concrete pouring process.

[0030] Reference Figure 1 、 5 , the raft steel mesh 19 is fixed to the bottom of the square frame 2 through a clamping assembly;

[0031] The clamping assembly includes a clamping block 14, a clamping block 15, a latch 17, and a slot 18. The clamping block 15 is fixed to the bottom of the square frame 2. The slot 18 is provided on the clamping block 15. The clamping block 14 is connected to the clamping block 15 through the clearance between the latch 17 and the slot 18. The connection on the raft steel mesh 19 is fixed between the clamping block 14 and the clamping block 15. The steel cage 13 is fixed on the clamping block 14.

[0032] It should be noted that the steel cage 13 can be fixed to the clamping block 14 by welding or threaded connection, as long as it can play a fixing role;

[0033] By adopting the above technical solution, the connection of the raft steel mesh 19 is fixed between the block 14 and the block 2 15, so that the raft steel mesh 19 is stably fixed at the bottom of the square frame 2, and cooperates with the splint 12 to make the entire steel structure more stable during concrete pouring.

[0034] Reference Figure 1 、 4 , a placement slot for the support block 4 is opened on the square frame 2, the bidirectional screw 5 rotates on the support block 4, the guide rod 6 is fixed on the support block 4, and a rocker 7 is rotatably provided on one side of the square frame 2. One end of the rocker 7 passes through the support block 4 and is splined with the bidirectional screw 5;

[0035] By adopting the above technical solution and providing the support block 4, it is convenient to remove the square frame 2 and the rocker 7 from the formed concrete column after the concrete is poured and formed.

[0036] Reference Figure 1-3 , connecting plates 8 are threadedly fixed to both sides of the square frame 2 by fastening bolts 9, and a limiting pin 16 is provided on the side of the connecting plate 8 close to the square frame 2, and the end of the limiting pin 16 away from the connecting plate 8 passes through the square frame 2 and abuts against the support block 4;

[0037] It should be noted that the square frame 2 is provided with a through hole for the limit pin 16 to pass through and a threaded hole for the fastening bolt 9 to pass through;

[0038] By adopting the above technical solution, tighten the fastening bolts 9 to make the connecting plate 8 stick to the square frame 2. At this time, the end of the limit pin 16 away from the connecting plate 8 abuts against the support block 4, fixing the support block 4 and keeping the movable plate 10 stable in movement.

[0039] Reference Figure 3 , when the inner surface of the plywood 12 is in contact with the outer surface of the corner reinforcement rib 3, the outer surface of the corner reinforcement rib 3 is simultaneously tangent to the two mutually perpendicular surfaces of the square frame 2;

[0040] By adopting the above technical solution, the edges of the corner reinforcement ribs 3 are in contact with the two vertical surfaces of the square frame 2, which not only maintains the vertical stability of the corner reinforcement ribs 3, but also ensures that the concrete pouring surface is more regular, reducing subsequent finishing work.

[0041] Reference Figure 1 , the square frame 2 is composed of two oppositely arranged concave frames;

[0042] It should be noted that the two concave frames can be fixed by bolts or snap fit;

[0043] By adopting the above technical solution, the square frame 2 is detachable, which makes it easy to remove the square frame 2 after the concrete is poured and formed, thereby ensuring the regularity of the concrete pouring surface.

At this time, the bidirectional screw rod 5, the guide rod 6 and the movable plate 10 are placed on the square frame 2 through the support block 4, so that the rocker 7 is splined with the bidirectional screw rod 5, and the rocker 7 is shaken to make the two movable plates 10 move away from each other, driving the splint 12 to clamp and fix the diagonal reinforcement 3, and then the steel cage 13 is fixed on the clamping block 14, so that the movable plate 10 is tangent to the outer surface of the steel cage 13, and concrete is poured into the square frame 2. After the concrete is formed, the square frame 2 and the rocker 7 can be removed to keep the surface of the concrete column regular.
