[0029] Such as Figures 1-5 , a concrete casting steel structure, comprising: a support platform 1, a casting steel structure 2 and a reinforcement frame 3;

[0030] The support platform 1 is provided with a platform opening 11; the lower end of the casting steel structure 2 is limited to the platform opening 11; the interior of the casting steel structure 2 is provided with a casting cavity 20 for casting concrete 10; a plurality of inner sidewalls of the casting cavity 20 are respectively provided with vertically extending limiting guide rails 121; the reinforcing frame 3 is provided with a clamping block 31 and a vertical baffle 32; the clamping block 31 is provided with a clamping groove 33; the clamping groove 33 is movably clamped to the limiting guide rail 121; the vertical baffles 32 of the reinforcing frame 3 located on different inner sidewalls of the casting cavity 20 surround to form a reinforcing cavity 30; the reinforcing frame 3 is provided with a plurality of plate hollow openings 34, and the interior of the reinforcing cavity 30 communicates with the outside.

[0031] This solution provides a concrete casting steel structure. By designing the limiting guide rail 121 inside the casting steel structure 2 and using the clamping groove 33 of the external reinforcing frame 3 to be clamped to the limiting guide rail 121, a reinforcing cavity 30 can be formed by surrounding the vertical baffles 32 of the reinforcing frame 3 between multiple inner sidewalls. When the casting steel structure 2 is being cast, the concrete 10, the reinforcing frame 3, and the casting cavity 20 can be integrally combined, which can improve the overall strength of the concrete casting steel structure and solve the problem of insufficient strength in the existing casting steel structure where only concrete 10 is cast.

[0032] Specifically, the support platform 1 is mainly placed in the pit below the ground; the support platform 1 is provided with a platform opening 11, and the lower end of the casting steel structure 2 is clamped to the platform opening 11 to support the casting steel structure 2; the casting steel structure 2 is provided with a casting cavity 20 for casting concrete 10. When the concrete 10 solidifies, a solid structure can be formed inside the casting steel structure 2 to improve the internal strength of the casting steel structure 2; and this solution also provides limiting guide rails 121 on multiple inner sidewalls of the casting cavity 20; the limiting guide rails 121 can extend from the top to the bottom, or from the middle to the bottom, or from the top to the middle, etc.; the reinforcing frame 3 is provided with a clamping block 31, and the clamping groove 33 of the clamping block 31 can be clamped to the limiting guide rail 121, so that it can move along the extending direction of the limiting guide rail 121; and the mutual clamping of the limiting guide rail 121 and the clamping groove 33 can prevent the reinforcing frame 3 from separating from the inner sidewall of the casting cavity 20; in this regard, when the reinforcing frame 3 is provided on multiple inner sidewalls of the casting cavity 20, the vertical baffles 32 of the reinforcing frames 3 on different inner sidewalls surround to form a reinforcing cavity 30; since the reinforcing cavity 30 communicates with the outside through the multiple plate hollow openings 34 of the reinforcing frame 3, when the concrete 10 is being distributed, the concrete 10 will also enter the reinforcing cavity 30 through the plate hollow openings 34 when filling the casting cavity 20. When the concrete 10 solidifies, the concrete 1, the reinforcing frame 3, and the casting cavity 20 can be integrally combined; in this way, the cured concrete 10 still has the reinforcing frame 3 inside, which can further increase the overall strength of the concrete casting steel structure, thus solving the problem of insufficient strength in the existing casting steel structure where only concrete 10 is cast.

[0033] Optimally, a plurality of the reinforcing frames 3 are provided on a single limiting guide rail 121, and the plurality of reinforcing frames 3 are vertically stacked.

[0034] In some embodiments, a single limiting guide rail 121 may be correspondingly connected to a single reinforcing frame 3; in the optimal embodiment, the number of the reinforcing frames 3 is plural, and the plurality of reinforcing frames 3 are respectively clamped to the limiting guide rail 121 through clamping grooves 33. The reinforcing frames 3 are stacked vertically. The reinforcing frames 3 can be installed on the same limiting guide rail 121 step by step, without lifting a single reinforcing frame 3 to a certain height and then extending it downward into the pouring cavity 20, reducing the assembly difficulty. Further, the concrete can be poured step by step in this solution. For example, some of the reinforcing frames 3 can be installed relatively below the limiting guide rail 121 first, then the concrete is poured, and then some of the reinforcing frames 3 are stacked on the reinforcing frames 3 exposed above the concrete, and then the concrete is continuously poured.

[0035] Optimally, some of the reinforcing frames 3 are provided with a top block 35 at the upper end of the vertical baffle 32 and a bottom groove 36 at the lower end of the vertical baffle 32; when the reinforcing frames 3 are vertically stacked, the reinforcing frame 3 located relatively below is clamped to the bottom groove 36 of the reinforcing frame 3 located relatively above through the top block 35.

[0036] To improve the connection tightness and regularity of the reinforcing frames 3 in vertical stacking, when the plurality of reinforcing frames 3 are vertically stacked, the upper and lower adjacent top blocks 35 and bottom grooves 36 can be clamped to fix the relative positions of the upper and lower two reinforcing frames 3, and the vertical baffles 32 are kept in a straight stack, and the reinforcing frames 3 can be kept in a regular stacked state, which can ensure the most stable structure when using the split-type reinforcing frames 3.

[0037] Optimally, the top block 35 is located at the top of the reinforcing frame 3; the top block 35 is provided with a lifting opening 37.

[0038] The top block 35 is located at the top of the reinforcement frame 3. When the height of the cast steel structure 2 is relatively high, directly lowering the reinforcement frame 3 downward may damage the cast steel structure 2. In this regard, in this solution, a hanging opening 37 is provided on the top block 35. The hanging rope is directly passed downward around the hanging opening 37 and then upward. The two ends of the hanging rope are located outside the casting cavity 20. After the clamping groove 33 of the reinforcement frame 3 is clamped to the limit guide rail 121, it falls along the limit guide rail 121. Then, by controlling the two ends of the hanging rope, the hanging rope is slowly lowered, so that the reinforcement frame 3 presses downward against the lower reinforcement frame 3 until the bottom groove 36 of the lifted reinforcement frame 3 drops to the top block 35 of the lower reinforcement frame 3. Then, control one end of the hanging rope to move upward and release the other end of the hanging rope, so as to wind the hanging rope out of the hanging opening 37, and complete the installation of a single reinforcement frame 3 on the limit guide rail 121. In addition, since there are multiple inner walls in the casting cavity 20, the reinforcement frames 3 can be hoisted onto the limit guide rails 121 of multiple inner walls simultaneously without interference, which can shorten the installation time of the reinforcement frames 3.

[0039] Optimally, the outer diameter of part of the top block 35 gradually decreases from bottom to top, so that the outer side surface of the top block 35 forms a guiding inclined surface 38; the inner wall of the bottom groove 36 is attached to the guiding inclined surface 38.

[0040] During hoisting, to improve the docking efficiency between the top block 35 and the bottom groove 36, in this solution, the outer diameter of the top block 35 can be designed as a guiding inclined surface 38. When the reinforcement frame 3 is lowered, the top block 35 of the lower reinforcement frame 3 has a minimum diameter at the upper end. Therefore, the top of the top block 35 is most likely to extend into the bottom groove 36 of the reinforcement frame 3. Subsequently, under the guiding action of the guiding inclined surface 38, the upper and lower reinforcement frames 3 are aligned, thus ensuring the regular stacking of the reinforcement frames 3.

[0041] Optimally, the casting cavity 20 is provided with four inner walls, and the vertical baffles 32 of the four inner walls are in contact with or connected to each other.

[0042] The casting cavity 20 is provided with four inner walls, and the vertical baffles 32 of each inner wall abut against or are connected to each other, which can improve the connection tightness between multiple reinforcement frames 3 and can further improve the overall strength of the concrete-cast steel structure. The vertical baffles 32 can be in contact only with each other, or can be connected by known methods (such as clamping with a card slot and a card block, screw fixing, etc.).

[0043] Optimally, the reinforcement frame 3 is provided with frame side plates 39; the frame side plates 39 are arranged on both sides of the vertical baffle 32; the frame side plates 39 and the vertical baffle 3 each are provided with the plate hollow openings 34.

[0044] On both sides of the vertical baffle 32, frame side plates 39 are provided. The vertical baffle 32 and the frame side plates 39 are respectively provided with plate hollow openings 34. The plate hollow openings 34 can reduce the overall weight of the reinforcement frame 3, facilitate manual lifting of the reinforcement frame 3, and also facilitate manual control of lifting the reinforcement frame 3 by a plumb line. At the same time, the vertical baffle 32 and the frame side plates 39 are respectively provided with plate hollow openings 34, which can enable the concrete 10 in the pouring cavity 20 to quickly enter and exit the inside and outside of the reinforcement cavity 30, improving the pouring efficiency of the concrete 10 in the pouring cavity 20.

[0045] Optimally, a plurality of the limiting guide rails 121 are provided on a single inner side wall of the pouring cavity 20; a side frame groove 391 is provided on a part of the frame side plates 39, and the side frame groove 391 is movably clamped to one of the limiting guide rails 121.

[0046] The pouring cavity 20 can be provided with a plurality of limiting guide rails 121 on a single inner side wall. The reinforcement frame 3 is provided with a side frame groove 391 and a clamping groove 33. The side frame groove 391 and the clamping groove 33 can be respectively clamped to different limiting guide rails 121, thereby increasing the connection points between the reinforcement frame 3 and the pouring cavity 20 and improving the fixing stability of the reinforcement frame 3 in the pouring cavity 20.

[0047] Optimally, the support platform 1 is provided with a platform pouring cavity 13, and the platform pouring cavity 13 exposes the platform opening 11; the pouring steel structure 2 is provided with a pouring outer opening 21 in the area extending into the platform opening 11. The outer end of the pouring outer opening 21 communicates with the platform pouring cavity 13, and the inner end of the pouring outer opening 21 communicates with the pouring cavity 20.

[0048] The platform pouring cavity 13 can be used to accommodate the pouring steel structure 2. The lower end of the pouring steel structure 2 extends into the platform pouring cavity 13 through the platform opening 11. When pouring the concrete 10 into the pouring cavity 20 of the pouring steel structure 2, the concrete 10 is output to the platform pouring cavity 13 through the pouring outer opening 21, thereby integrally fixing the support platform 1, the pouring steel structure 2 and the reinforcement frame 3 by the concrete 10 and improving the connection tightness among the three.

[0049] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
