[0023] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.
[0024] Reference Figures 1 to 4 This embodiment provides a frame mechanism based on filling box positioning, including,
[0025] The steel reinforcement assembly 1 includes a top steel reinforcement frame 11 and a bottom steel reinforcement frame 12 arranged opposite to each other. A steel reinforcement stirrup 13 is provided between the top steel reinforcement frame 11 and the bottom steel reinforcement frame 12. The top steel reinforcement frame 11, the bottom steel reinforcement frame 12 and the steel reinforcement stirrup 13 form an accommodating space 14.
[0026] Filling box 2 is disposed within the receiving space 14;
[0027] The positioning component 3 includes a box body 31 disposed on the upper part of the filling box 2. The upper end of the box body 31 is open, and a movable part 32 is disposed at the upper end of the opening of the box body 31. The upper end of the movable part 32 abuts against the top steel frame 11, and a stop part 33 is disposed between the box body 31 and the movable part 32.
[0028] The bottom steel reinforcement frame 12 is arranged on the ground, and then the steel reinforcement stirrups 13 are vertically tied to the bottom steel reinforcement frame 12 with galvanized iron wire to form a rib beam. When the steel reinforcement stirrups 13 are tied, a space 14 is left for the filling box 2. Then the box body 31, the movable part 32 and the stop part 33 are fixed as a whole as a pad structure on the upper part of the filling box 2. Multiple pad structures can be placed. Then the top steel reinforcement frame 11 is tied to the upper end of the steel reinforcement stirrups 13 with galvanized iron wire. Finally, the position of the movable part 32 is adjusted upward so that the top of the movable part 32 abuts against the top steel reinforcement frame 11, and the position of the movable part 32 is fixed by the stop part 33.
[0029] Because the pad structure composed of box 31, movable part 32 and stop part 33 is placed between filling box 2 and top steel frame 11, it forms a vertical limit on filling box 2, restricting its movement in the vertical direction and preventing filling box 2 from floating when pouring concrete.
[0030] Reference Figure 4 As an optional embodiment, the stop member 33 includes a plurality of threaded holes 331 spaced apart on the housing 31 in the vertical direction, one of which is internally threaded with a first bolt 332, the inner end of the first bolt 332 abutting against the movable member 32.
[0031] The stop 33 uses a screw to tighten the movable part 32, which is convenient to operate. Specifically, after the movable part 32 is adjusted to a suitable height, the first bolt 332 is screwed into the threaded hole 331 that can abut against the movable part 32, and then the first bolt 332 is screwed inward to make the first bolt 332 press tightly against the movable part 32.
[0032] Reference Figure 5 As an optional embodiment, the positioning component 3 also includes a pad 34 disposed at the lower part of the filling box 2, with the lower end of the pad 34 abutting against the bottom steel reinforcement frame 12.
[0033] The pad 34 is used when there is a large distance between the top steel bar frame 11 and the bottom steel bar frame 12, so as to prevent the movable part 32 from not being able to contact the top steel bar frame 11 when it is adjusted to the maximum height, and to ensure the limiting effect on the filling box 2.
[0034] Reference Figure 3 As an optional embodiment, the positioning component 3 also includes a crossbar 35 disposed on the side wall of the filling box 2, and a clamp 36 is disposed at the end of the crossbar 35 away from the filling box 2, and the clamp 36 is attached to the reinforcing bar 13.
[0035] The horizontal bar 35 and the clamp 36 provide auxiliary positioning for the filling box 2. Specifically, after the filling box 2 is placed, the clamp 36 tightly hugs the steel stirrup 13, forming a horizontal and vertical positioning for the filling box 2, further ensuring the stability of the filling box 2 after placement and preventing the filling box 2 from moving during subsequent pouring.
[0036] Reference Figure 3 As an optional embodiment, the crossbar 35 includes a sleeve 351 with one end fixed to the side wall of the filling box 2, and an inner rod 352 slidably disposed at the other end of the sleeve 351. A second bolt 353 is disposed between the sleeve 351 and the inner rod 352.
[0037] The crossbar 35 adopts a telescopic bar structure composed of sleeve 351 and inner bar 352. After the filling box 2 is placed, the length of the crossbar 35 can be adjusted according to the distance between the filling box 2 and the steel reinforcement 13 to ensure that the clamp 36 can be clamped on the steel reinforcement 13. After the length of the crossbar 35 is adjusted, the relative position of sleeve 351 and inner bar 352 is fixed by the second bolt 353 to ensure the lateral limit of the filling box 2.
[0038] Reference Figure 3 As an optional embodiment, the clamp 36 includes a first arc-shaped plate 361 fixed to the end of the inner rod 352 away from the sleeve 351, a second arc-shaped plate 362 is disposed opposite to one side of the first arc-shaped plate 361, and a third bolt 363 is disposed between the first arc-shaped plate 361 and the second arc-shaped plate 362.
[0039] The first arc plate 361 and the second arc plate 362 are arranged opposite to each other to form a clamp 36. After the clamp 36 is clamped onto the reinforcing bar stirrup 13, the first arc plate 361 and the second arc plate 362 are tightened by the third bolt 363 so that the clamp 36 is tightly secured to the reinforcing bar stirrup 13.
[0040] Reference Figure 1 As an optional embodiment, both the top steel reinforcement frame 11 and the bottom steel reinforcement frame 12 are grid-shaped steel reinforcement frames.
[0041] Both the top steel reinforcement frame 11 and the bottom steel reinforcement frame 12 are made by arranging steel bars in a crisscross pattern and binding them with galvanized iron wire.
[0042] Reference Figure 1 and Figure 2 As an optional embodiment, the reinforcing bar 13 is a vertically arranged square frame, with the upper end of the reinforcing bar 13 clamped on the top reinforcing bar frame 11 and the bottom end of the reinforcing bar 13 clamped on the bottom reinforcing bar frame 12.
[0043] The upper and lower ends of the reinforcing bar stirrups 13 are tied to the top reinforcing bar frame 11 and the bottom reinforcing bar frame 12 with galvanized iron wire, respectively.
[0044] Reference Figure 3 As an optional embodiment, the filling box 2 is provided with a grout leakage hole 21. The grout leakage hole 21 is vertically arranged and penetrates the upper and lower end surfaces of the filling box 2. The upper end of the grout leakage hole 21 is funnel-shaped.
[0045] A grout leakage hole 21 is provided on the filling box 2 to allow concrete to flow in during concrete pouring. The upper end of the grout leakage hole 21 is designed in the shape of a funnel to facilitate the flow of concrete.
[0046] Reference Figure 5 A prestressed hollow slab includes an upper frame structure and a concrete layer 4, which is poured onto the frame structure.
[0047] The filling box 2 is vertically limited by the pad structure composed of the box body 31, the movable part 32 and the stop part 33. The filling box 2 is horizontally and vertically assisted in positioning by the crossbar 35 and the clamp 36, so as to prevent the filling box 2 from floating or moving during concrete pouring and to ensure the quality of the hollow slab after pouring.
[0048] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
