Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a steel plate embedded structure for controlling cracks in steel fiber concrete floors. Background Art

[0002] In modern building construction, the durability and aesthetics of the floor are of crucial importance. Steel fiber concrete and emery floors are widely used in the construction of the first-floor floor due to their excellent performance. However, during the construction of the steel fiber floor, due to the overall large area of the floor concrete project, the concrete will shrink during the hardening process. When the shrinkage is restricted, tensile stress will be generated inside the concrete. If the tensile stress exceeds the tensile strength of the concrete, cracks will occur on the surface or inside of the concrete. The large-area floor concrete is more likely to produce uneven shrinkage during the hardening process, resulting in the appearance of irregular cracks. Irregular cracks are likely to appear after construction. These cracks not only affect the aesthetics of the floor but also may pose potential threats to the service life and safety of the floor.

[0003] To solve this problem, in the prior art, construction workers usually manually cut dividing joints on the steel fiber floor concrete. Although this method can reduce the generation of cracks to a certain extent, the labor cost is high and the efficiency is low. Therefore, how to reduce the labor cost and improve the construction efficiency has become an urgent problem to be solved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a steel plate embedded structure for controlling cracks in steel fiber concrete floors to solve the problem of irregular cracks caused by the too large area of the steel fiber concrete floor in the prior art.

[0005] To achieve the above purpose, the specific technical solution of a steel plate embedded structure for controlling cracks in steel fiber concrete floors of the utility model is as follows:

[0006] A steel plate embedded structure for controlling cracks in steel fiber concrete floors includes the ground beam of a building. Flat steel for separating concrete is installed on both sides of the ground beam. The flat steel on both sides of the ground beam is welded and connected by a number of short threaded steel bars. A long threaded steel bar is arranged vertically to the short threaded steel bars at the upper ends of the short threaded steel bars. The connection between the long threaded steel bar and the short threaded steel bars is fixed by tying with iron wire. By installing flat steel for separating concrete on both sides of the ground beam, the stress concentration caused by concrete shrinkage can be effectively dispersed and reduced, thereby reducing the generation of cracks and preventing the generation of irregular cracks caused by the too large area of the concrete. The welded connection between the short threaded steel bars and the flat steel further enhances the stability and integrity of the structure.

[0007] Furthermore, the flat steel is set as galvanized flat steel with a thickness of 50 mm. Using 50-mm-thick galvanized flat steel can provide greater stiffness and strength, thus more effectively separating the concrete, reducing stress concentration caused by shrinkage, and lowering the possibility of crack generation. In addition, this thickened and galvanized flat steel also has good impact resistance and can remain stable under external load, being not easily deformed or damaged.

[0008] Furthermore, the short deformed steel bars are set as deformed steel bars with a diameter of 12 mm. Using 12-mm-diameter deformed steel bars can provide greater bearing capacity and tensile strength. At the same time, the welded connection between the deformed steel bars of this size and the flat steel is more firm and reliable, which can enhance the stability and integrity of the entire structure, ensuring that the concrete shrinks evenly during the hardening process.

[0009] Furthermore, the spacing between the two short deformed steel bars is set as 300 mm. This spacing setting helps to enhance the stability and integrity of the entire structure. An appropriate spacing can make the welded connection between the short deformed steel bars and the flat steel more firm and reliable.

[0010] Furthermore, two long deformed steel bars are arranged on the short deformed steel bars. By arranging two long deformed steel bars on the short deformed steel bars, the bearing capacity and tensile strength of the entire structure can be further enhanced. At the same time, the durability and service life of the structure can also be enhanced. The additional long deformed steel bars provide better support and fixation, enabling the structure to remain stable during long-term use.

[0011] The steel plate embedded structure for controlling cracks in steel fiber concrete ground provided by the present utility model has the following advantages:

[0012] By installing galvanized flat steel on both sides of the ground beam, the flat steel serves as a separation joint for the steel fiber concrete to separate and control the cracks in the steel fiber concrete. It can be automatically separated into joints during the pouring process of the steel fiber ground concrete, thereby controlling the construction quality of the steel fiber ground and reducing the construction cost of manual jointing in the later stage. At the same time, due to the connection of the 12-mm-diameter short deformed steel bars, the flat steel on both sides of the ground beam can be effectively fixed. Also, due to the arrangement of the long deformed steel bars, the strength of the concrete inside the ground beam can be effectively enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Refer to Figures 1-4 , the present utility model provides a steel plate embedded structure for controlling cracks in a steel fiber concrete floor, which is used in the construction of super high-rise buildings. A steel plate embedded structure for controlling cracks in a steel fiber concrete floor includes the ground beam 1 of a building. Galvanized flat steel 2 for separating concrete is installed on both sides of the ground beam 1. The flat steel 2 on both sides of the ground beam 1 is welded and connected by a number of short threaded steels 3. The interval between the short threaded steels 3 is set to 300 mm. A long threaded steel 4 perpendicular to the short threaded steel 3 is arranged at the upper end of the short threaded steel 3. The connection between the long threaded steel 4 and the short threaded steel 3 is fixed by tying with iron wire.

[0020] During the production of a building with a ground constructed by using a steel fiber concrete construction process or a diamond abrasive floor construction process, first, 5-mm-thick galvanized flat steel 2 is arranged on both sides of the ground beam 1. Before pouring concrete, the galvanized flat steel 2 is installed on both sides of all the ground beams 1. The flat steel 2 on both sides of the ground beam 1 is connected by short threaded steels 3 with a diameter of 12 mm. One short threaded steel 3 is arranged every 300 mm on the ground beam 1. After all the short threaded steels 3 are arranged, a long threaded steel 4 is laid on the upper end of the arranged short threaded steels 3. The long threaded steel 4 is perpendicular to the short threaded steel 3. The two ends of the long threaded steel 4 are connected to the columns connected to both ends of the ground beam 1. The connection between the long threaded steel 4 and the short threaded steel 3 is fixed by tying with steel wire, completing the embedding of the steel plate. Subsequently, concrete is poured. The steel fiber concrete inside the flat steel 2 and the steel fiber concrete outside the flat steel 2 form a separation joint through the flat steel 2, controlling the generation of cracks in the steel fiber concrete.

[0021] The connection structure of the present application has the following beneficial effects:

[0022] By installing galvanized flat steel 2 on both sides of the ground beam 1, the flat steel 2 serves as a steel fiber concrete dividing joint to divide and control the steel fiber concrete, enabling it to be automatically divided into joints during the pouring process of the steel fiber floor concrete, thereby controlling the construction quality of the steel fiber floor and reducing the construction cost of manual jointing in the later stage. At the same time, due to the connection of the short threaded steel 3 with a diameter of 12 mm, the flat steel 2 on both sides of the ground beam 1 can be effectively fixed. Additionally, due to the arrangement of the long threaded steel 4, the strength of the concrete inside the ground beam 1 can be effectively enhanced.

[0023] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
