Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building engineering, in particular to a column top reinforcement structure of a flat slab floor without beams. Background Technique
[0002] A flat slab floor without beams is a structural system in which there are no beams and the floor slab is directly supported on columns. The floor load is directly transmitted to the foundation through the columns. However, it has the defects of being sensitive to uneven loads and having weak structural anti-collapse ability, and it needs to be effectively reinforced.
[0003] After retrieval, a Chinese patent with the publication number CN220487182U discloses a column cap reinforcement device for a flat slab floor without beams, which includes a reinforcement component. Above the concrete column is a concrete column cap, and above the concrete column cap is a concrete floor slab. The reinforcement component is obliquely fixed on the concrete column cap and the concrete column. The reinforcement component includes a number of inclined strut steel pipes. The angles formed by the number of inclined strut steel pipes and the concrete floor slab are equal, and the number of inclined strut steel pipes are arranged at intervals of 90° in the plane.
[0004] Based on the above retrieval and in combination with the prior art, it is found that;
[0005] The above patent only reinforces the bottom of the flat slab floor without beams and cannot reinforce its top. For the traditional reinforcement of the flat slab floor without beams, generally, methods such as adding primary and secondary beams, adding reinforced concrete support columns or prestressed CFRP reinforcement are used. However, no matter which method is used, the reinforcement work is relatively large and the reinforcement structure is relatively complex, so there are certain limitations. Content of the Utility Model
[0006] In order to solve the above technical problems, the utility model proposes a column top reinforcement structure of a flat slab floor without beams. By using this reinforcement method, not only can the reinforcement effect be improved, but also the construction is convenient and efficient, and it has good economy and safety.
[0007] The technical solution for achieving the purpose of the utility model is: a column top reinforcement structure of a flat slab floor without beams, including a flat slab floor without beams. Multiple groups of holes are opened on the top surface, bottom surface and side surface of the flat slab floor without beams. An anchor bar is fixedly installed inside each hole. A first stirrup is fixedly installed together among the multiple anchor bars located on the bottom surface and the side surface, and a second stirrup is fixedly installed together among the multiple anchor bars located on the top surface.
[0008] Preferably, a plurality of hoop bars are fixedly installed on both the first stirrup and the second stirrup.
[0009] Preferably, an upper reinforcement layer and a lower reinforcement layer are respectively poured on the top and bottom of the flat slab floor without beams. Compared with the prior art, the remarkable advantages of this utility model are:
[0010] First: The utility model roughens the surface of the flat slab without beams first, which is convenient for subsequent pouring of concrete to form a reinforcement layer. In addition, the stirrup one and the stirrup two are tied together by anchor bars to form a steel reinforcement cage structure, which is convenient for improving the structural strength of the reinforcement layer and at the same time improving the structural strength of the flat slab without beams, making it more stable and firm.
[0011] Second: The utility model forms a steel reinforcement cage by multiple groups of steel bars, with a simple structure and convenient construction. Moreover, the upper reinforcement layer and the lower reinforcement layer after pouring have better structural strength, and have better economy and safety.
[0012] It solves the problem that the above-mentioned patent only strengthens the bottom of the flat slab without beams and cannot strengthen its top, while the traditional reinforcement of the flat slab without beams generally adopts methods such as adding primary and secondary beams, adding reinforced concrete support columns or prestressed CFRP reinforcement. However, no matter which method is used, the reinforcement work has a large amount of work and the reinforcement structure is relatively complex. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following details the utility model, clearly and completely describes the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.
[0019] The utility model provides a column top reinforcement structure for a flat slab without beams by improvement. The technical solution of the utility model is:
[0020] As Figure 1-2As shown in the figure, a reinforced structure for the top of a flat slab column includes a flat slab without beams 1. Multiple groups of holes 4 are provided on the top surface, bottom surface, and side surface of the flat slab without beams 1. An anchor bar 5 is fixedly installed inside each hole 4. A first stirrup 6 is fixedly installed together among multiple anchor bars 5 located on the bottom surface and side surface, and a second stirrup 7 is fixedly installed together among multiple anchor bars 5 located on the top surface. By arranging anchor bars 5 at the top and bottom of the flat slab without beams 1, support is provided for tying the first stirrup 6 and the second stirrup 7, thus facilitating the subsequent pouring of concrete to form a reinforced layer.
[0021] Furthermore, multiple hoop bars 8 are fixedly installed on both the first stirrup 6 and the second stirrup 7. By arranging the hoop bars 8, a steel cage structure is formed in combination with the first stirrup 6 and the second stirrup 7, thus facilitating the improvement of the structural strength of the poured concrete reinforced layer, and thus realizing the reinforcement effect on the flat slab without beams 1.
[0022] Furthermore, an upper reinforced layer 2 and a lower reinforced layer 3 are respectively poured on the top and bottom of the flat slab without beams 1, and the flat slab without beams 1 is reinforced by pouring the upper reinforced layer 2 and the lower reinforced layer 3.
[0023] The specific working method is as follows: First, roughen the surface of the flat slab without beams 1. The roughening step facilitates subsequent construction. Then, make holes 4, and then perform bar planting, implant the anchor bars 5 into the holes 4, tie the first stirrup 6 and the second stirrup 7 to the anchor bars 5, and then tie the hoop bars 8 to the first stirrup 6 and the second stirrup 7 to form a steel cage structure, thus facilitating the pouring of the upper reinforced layer 2 and the lower reinforced layer 3. In addition, the steel cage structure is simple and has high structural strength, which can improve the structural strength of the upper and lower two reinforced layers, thus ensuring the reinforcement effect on the flat slab without beams 1, and being convenient for rapid construction while having high economy and safety. The reinforcement structure of increasing the cross-section by bar planting on the top and bottom surfaces has a simple and convenient construction method and good reinforcement effect.
