Description

Technical Field

[0001] The invention relates to the technical field of steel concrete construction, in particular to a steel concrete construction pouring structure. Background Art

[0002] Steel-concrete construction structure (also known as rigid concrete structure) is a composite structural system. Its core feature is that the steel frame is used as the main load-bearing component, and reinforced concrete is wrapped around it to form a whole and work together.

[0003] The traditional steel concrete construction operation steps are: fixing the steel - tying the steel cage - installing the mold - sealing the steel - grouting. During the mold installation process, workers need to visually adjust the distance between each surface of the mold inner wall and the steel cage to ensure that the steel bars and the inner wall of the mold do not contact each other.

[0004] However, due to the influence of traditional structures, the mold needs to be fixed separately to prevent the various surfaces of the mold from shifting to one side due to uneven force during the grouting process, thereby preventing the inner wall of the mold from contacting the steel cage during movement. In addition to adding an additional fixed structure to the mold, the mold disassembly and assembly steps will be numerous, which is not conducive to rapid disassembly and assembly. At the same time, when pouring concrete in the existing steel-concrete structure, the pump pipe output lacks a material guide structure, and manual control of the pump pipe outlet is required to circulate and swing along the gap between the mold and the steel section, which is time-consuming and labor-intensive. Summary of the Invention

A number of bolts for improving the anchoring force between the steel section 1 and the concrete are arranged on the outer wall of the steel section 1, and a steel cage 2 is arranged around the outside of the steel section 1. The mold is wrapped around the outside of the steel cage 2 and is gap-matched with the steel cage 2. The mold includes a U-shaped plate 3 and a side cover 8. A female buckle 7 with a socket 71 is respectively arranged on both sides of the side end opening of the U-shaped plate 3. A fixed plate 9 is respectively arranged on both sides of the side cover 8. A pin 10 is arranged on the fixed plate 9. The pin 10 passes through the socket 71 and is slidably connected to the inner wall thereof. A slider 11 is slidably arranged on the pin 10. A spring rod 12 is arranged on the slider 11. The movable end of the spring rod 12 is connected to a wedge-shaped block 13. One end of the wedge-shaped block 13 extends out of the pin 10 and abuts against the side of the female buckle 7 away from the side cover 8. The fixed plate 9 is provided with a driving component A for driving the slider 11 to slide, a slide groove 1001 is provided on the latch 10, and two through holes 1002 connected with the slide groove 1001 are symmetrically provided on the latch 10, the slider 11 is located in the slide groove 1001 and is slidably connected to its inner wall, a limiting groove is provided on the slider 11, the spring rod 12 is located in the limiting groove, and the fixed end of the spring rod 12 is connected to the bottom surface of the limiting groove, one end of the wedge-shaped block 13 is inserted into the limiting groove and is connected to the movable end of the spring rod 12, and the maximum distance between the through hole 1002 and the fixed plate 9 is smaller than the maximum distance between the slide groove 1001 and the fixed plate 9. Drive assembly A includes a screw A14, a worm wheel 15, and a worm 16. One end of the screw A14 is rotatably connected to the fixed plate 9, and the other end is inserted into the slide groove 1001 and rotatably connected to the latch 10. The screw A14 passes through the slider 11 and is spirally connected thereto. The worm wheel 15 is rotatably mounted on the fixed plate 9 and is coaxially connected to the screw A14. The worm 16 is rotatably mounted on the fixed plate 9 and meshes with the worm wheel 15. A crank A17 is provided on the end of the worm 16 extending out of the fixed plate 9. When the slider 11 slides to its farthest position from the fixed plate 9, the wedge-shaped block 13 retracts into the latch 10. The distance assemblies include four groups, which are respectively arranged on the four sides of the mold to adjust the distance between the inner wall of the mold and the outer wall of the section steel 1. The distance assembly includes a bracket 18, a slide 19, a slide rod 20, and a screw B21. Bracket 18 is connected to the outer wall of the mold. Slide 19 is slidably mounted on bracket 18. Slide rod 20 is vertically connected to the side of slide 19 closest to the mold. The end of slide 20 away from slide 19 is inserted into the mold and slidably connected to the mold. Screw B21 is rotationally connected to bracket 18, passes through slide 19, and is spirally connected thereto. A crank B22 is provided on the end of screw B21 away from the mold. A scale 181 is provided on bracket 18 along the sliding direction of slide 19. A pointer 191 is provided on slide 19, with its tip pointing toward the scale on scale 181. A grouting hopper 23 is connected to the top of the mold. A pressure cap 24 is provided on the inside of grouting hopper 23. A feed hole 231 for injecting grout into the gap between the steel section 1 and the mold is provided between the inner wall of grouting hopper 23 and pressure cap 24.

[0031] In this embodiment, during actual operation, the steel section 1 is fixed on the base, and then the steel cage 2 is tied on the outer peripheral side of the steel section 1, and then the mold composed of the U-shaped plate 3 and the side cover 8 is clamped on the outside of the steel cage 2, and the side cover 8 is plugged into the female buckle 7 through the pin 10, and then the crank A17 is rotated. The crank A17 drives the worm 16 to rotate, and then drives the worm gear 15 and the screw rod A14 to rotate, and the slider 11 slides until the wedge-shaped block 13 pops out from the side of the female buckle 7 away from the fixed plate 9, and then the crank A17 is rotated in the opposite direction to make the wedge-shaped block 13 cooperate with the fixed plate 9 to complete the locking operation of the U-shaped plate 3 and the side cover 8. When dismantling, the crank A17 is rotated forward to move the slider 11 to the end away from the fixed plate 9. At this time, the wedge-shaped block 13 automatically retracts because the inclined surface contacts the edge of the through hole 1002. At this time, the side cover 8 can be directly pulled out of the U-shaped plate 3. Then the slide bar 20 is driven to the reset state layer by layer to avoid the appearance of pores on the concrete due to the long-term retention of the slide bar 20.

[0032] Example 2

[0033] like Figure 1-Figure 3 and Figure 5 As shown, the steel-concrete construction pouring structure proposed by the present invention, compared with the first embodiment, has positioning brackets A4 and B6 respectively provided at both ends of the U-shaped plate 3. Positioning bracket A4 is provided with a positioning pin 5, and positioning bracket B6 is provided with a pin hole 61 adapted to the positioning pin 5. The bottom of the grouting bucket 23 is also provided with a positioning bracket B6.

[0034] In this embodiment, since the overall height of the steel section 1 is relatively large, in order to facilitate the transportation of the mold, the mold is made to a certain height. The upper mold is quickly assembled by aligning the pin hole 61 on the positioning frame B6 with the pin 5 on the positioning frame A4 at the top of the lower mold. The connection method between the grouting bucket 23 and the top mold is the same as the connection method between the two adjacent molds, which is convenient for disassembly and assembly, and can avoid relative lateral movement between the two adjacent molds and the mold and the grouting bucket 23.

[0035] Example 3

[0036] like Figure 1-Figure 5 As shown, the present invention also proposes a steel-concrete construction pouring method, which adopts the pouring structure described in any one of the first embodiment or the second embodiment, and the pouring method includes the following steps:

[0037] S1. Vertically connect the steel section 1 to the embedded fixing seat, and tie the steel cage 2 to the outside of the steel section 1.

[0038] S2. Clamp the U-shaped plate 3 to the outside of the steel cage 2 from one side, and move the side cover 8 close to the U-shaped plate 3 from the other side of the steel cage 2. Insert the pin 10 into the insertion hole 71 until the wedge-shaped block 13 pops out. Use the drive assembly A to drive the slider 11 to move until the upright surface of the wedge-shaped block 13 is in contact with the side of the female buckle 7 away from the fixing plate 9.

[0039] S3. Operate four sets of distance components respectively, and use the distance components to control the distance between the inner wall of the mold and the four surfaces of the steel section 1.

[0040] S4. Put the grouting bucket 23 on the top of the mold, and let the concrete flow down along the discharge hole 231 into the gap between the mold and the steel section 1. During the grouting process, the distance components are reset layer by layer.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
