[0002] With the development of my country's national economy, some super-large buildings are increasing, and large-area concrete floors are increasingly used in industrial plants, large exhibition halls and other buildings.

[0003] However, due to the large single-layer area, it is difficult to control the quality of the concrete surface flatness and ground cracks. Especially at the junction of the column and the ground, due to uneven settlement, it is very easy to cause cracks, which has a greater impact on factories with high flatness and crack requirements.

[0004] The existing technology adopts cutting square seams around the columns after the floor is constructed, but this method also has the disadvantage of stress concentration at the corners, which can easily cause cracks in the corner floor.

[0005] Therefore, there is an urgent need for a circular floor joint structure around the steel columns of a factory building and a construction method thereof to solve the above-mentioned technical problems. Summary of the invention

[0031] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0032] Figure 1 Schematic diagram of the structure of this embodiment. Figure 1 As shown, this embodiment provides a floor joint structure around the steel columns of a factory building, which is mainly aimed at large-area floor construction around the steel columns of an industrial factory building, and specifically includes a template 1, a fixing part 2 and an isolation part 3.

[0033] Among them, the template 1 includes a circular structure, and the cross-sectional diameter of the template 1 is larger than the cross-sectional length of the structural member; the floor concrete in this embodiment is set to be flush with the upper surface of the template 1.

[0034] Specifically, the template 1 in this embodiment is made of steel plates, and the joints of the steel plates are butt-welded. In the actual construction process, a circular steel mold with a diameter slightly larger than the size of the pile cap is made of steel plates for easy use.

[0035] By adopting the circular steel formwork 1, the elastic modulus of the steel formwork is very high, which can well fill the cracks and gaps of the concrete floor, prevent the infiltration of water and dust, and thus protect the floor from corrosion and damage. It is the preferred material for the floor joint structure formwork around the steel columns of this factory building. By setting the circular steel formwork 1 in conjunction with the fixings 2 and the isolation parts 3, the durability of the concrete floor can be improved, the service life of the floor can be extended, and within the entire design life of the building, the later maintenance cost is almost zero, which greatly reduces the later maintenance work.

[0036] The fixing member 2 is used to connect the template 1 and the structural member. The fixing member 2 in this embodiment adopts a steel bar structure, one end of the steel bar structure is connected to the template 1, and the other end of the steel bar structure is connected to the structural member 3, and the steel bar structure is evenly arranged along the circumference of the template 1.

[0037] Of course, in the actual construction process, the fixing member 2 may also adopt other structures that can connect the template 1 and the structural member. In this embodiment, a steel bar structure is preferred.

[0038] Figure 2 Schematic diagram of the cross-sectional structure of this embodiment, as shown in Figure 2 As shown, the isolating member 3 in this embodiment is arranged on the outside of the template 1, and is used to isolate the template 1 from the floor concrete. Specifically, the isolating member 3 in this embodiment adopts a compressed foam board.

[0039] The compressed foam board has the advantages of high strength, light weight, sound insulation, heat insulation, etc., and is the preferred material for the isolation member 3 disposed on the outside of the template 1 in this embodiment.

[0040] like Figure 2 As shown, this embodiment further includes a filling structure 4, which is arranged between the isolation member 3 and the ground. The filling structure 4 in this embodiment is made of silica gel.

[0041] The floor joint structure around the steel columns of this factory building, including formwork 1, fixings 2 and isolation parts 3, is suitable for various types of steel structures and concrete factory floors. By installing a circular steel formwork isolation belt around the column base, the stress concentration at the connection between the floor and the structural member (pile cap) can be effectively reduced, thereby preventing cracks and damage, and can play a role in avoiding cracking, settlement, shrinkage and deformation. It can also prevent the ground from having corners and unevenness, making the ground smoother and more beautiful. There is no need to remove the formwork after the floor is poured, the construction is efficient, a lot of labor and time are saved, continuous construction operations can be carried out, and the construction progress is guaranteed.

[0042] Figure 3 This is a flow chart of the construction method of the floor joint structure around the steel columns of the factory building in this implementation. Figure 3 As shown, this embodiment provides a construction method for the floor joint structure around the steel column of the above-mentioned factory building, including the following steps:

[0043] S1: circular template processing;

[0044] Specifically, it includes using steel plates to process and manufacture circular steel templates with a diameter slightly larger than the size of the pile cap.

[0045] S2: Prepare the construction ground, including ensuring the flatness of the base;

[0046] During construction, when constructing the ground cushion or foundation treatment, ensure the flatness of the base layer according to the requirements of the drawings to provide the necessary conditions for the installation of the steel formwork.

[0047] S3: Formwork installation, including reserving a space on the side of the formwork close to the floor concrete for installing the isolation piece;

[0048] When installing the steel formwork, corresponding space is reserved on one side of the floor concrete to accommodate the compressible isolation foam material.

[0049] S4: template fixation;

[0050] The specific construction includes fixing the steel formwork in a 4-point fixing manner and welding the joints of the steel formwork by butt welding;

[0051] S5: Install the isolation member and set a filling structure between the isolation member and the ground.

[0052] The specific operation method is that after the steel formwork is fixed, a compressed isolation foam board is used to isolate the outside of the steel formwork from the floor concrete, and silicone is used to fill the joints on the ground.

[0053] S6: pouring the concrete floor, including making the concrete floor flush with the upper surface of the formwork, and paying attention to the protection of the finished product after pouring.

[0054] With this construction method, a circular steel formwork isolation belt is installed around the column base to effectively reduce stress concentration at the connection between the floor and the structural member (pile cap), thereby preventing cracks and damage. The circular isolation belt does not require demolding and cutting, making it easy to operate.

[0055] The beneficial effects of this method include:

[0056] 1. Suitable for all types of steel structures and concrete factory floors. There is no need to remove the formwork after the floor is poured. The construction is efficient, saving a lot of labor and time. Continuous construction operations are possible, and the construction progress is guaranteed.

[0057] 2. The steel formwork has a very high elastic modulus, which can well fill the cracks and gaps in the concrete floor, prevent the infiltration of water and dust, and thus protect the floor from corrosion and damage.

[0058] 3. It can enhance the durability of concrete floors and extend the service life of the floors. Within the entire design life of the building, the subsequent maintenance cost is almost zero, which greatly reduces the subsequent maintenance work.

[0059] 4. It can prevent cracking, settlement, shrinkage and deformation, and can also prevent the ground from having corners and unevenness, making the ground smoother and more beautiful.

[0060] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
