AI Technical Summary
During the construction of steel structure houses, traditional concrete floor treatment methods lead to cracks at the connection between the concrete floor and the support/steel column, resulting in quality defects and the inability to split the joints.
An annular formwork surrounded outside the support platform is used to form an inner pouring area and an outer pouring area to prevent the steel bar binding layer from penetrateing the support platform, form a partition structure, and use the gap caused by the formwork to release stress to realize the separation between the support platform and the concrete floor.
Through the split structure, the deformation stress on the concrete floor at the bearing/steel column cannot be released, resulting in crack problems, ensure the stability and safety of the engineering structure, and at the same time improve the load-bearing capacity of the concrete floor.

Description
Technical Field
[0001] The utility model relates to the technical field of floor slabs, in particular to a seam structure for steel columns of a floor bearing platform on a floor slab Background Art
[0002] In the modern construction field, steel structure houses are increasingly widely used, and their unique advantages and characteristics are deeply favored by architects and owners. However, in the construction process of steel structure houses, the treatment of the ground has always been a key link. At present, the following methods are mainly used for the construction of the ground of steel structure houses: concrete pouring, floor tile laying, wooden floor installation, etc. Among them, concrete pouring is the most commonly used method, which has the characteristics of high strength and long service life. However, traditional construction methods often have some problems; as Figure 1 As shown, it is a schematic structural diagram of a steel column 210 of a floor bearing platform 200 on a floor slab 300 in the prior art; among them, the bearing platform 200 refers to a reinforced concrete platform connecting the tops of each pile set at the top of the pile foundation to bear and distribute the load transmitted by the pier body; the top of the bearing platform 200 is used to connect with the steel column 210 to form a supporting force structure; as an important load transfer structure, the bearing platform 200 needs to have good connection stability with the concrete floor during ground pouring, so the construction method of laying steel bars throughout is adopted, that is, steel bars are laid throughout above the floor slab 300, generally a first steel bar binding layer 310 and a second steel bar binding layer 320 are set, and then the bearing platform 200 is set on the laid steel bar layer. The ground outside the bearing platform 200 is sequentially provided with a first concrete layer 330, a first fiber mesh layer 340, a second concrete layer 350, a second fiber mesh layer 360, and a surface layer 370 from bottom to top to form a concrete floor; after the bearing platform 200 and the ground are poured, the steel bar binding layer completely penetrates the bearing platform 200 to achieve the stable connection between the bearing platform 200 and the steel bar binding layer. The steel bar binding layer can play the role of resisting bending and improve the stability of the bearing platform 200 to avoid deformation when it is compressed; such a structure can greatly ensure the stability of the structure of the bearing platform 200 and the steel column 210 during the later use process. However, the concrete floor is not completely rigid and actually has a certain flexibility. Especially when used in a factory building structure, after the load on the concrete floor increases, over time, cracks will occur at the positions of the concrete floor and the steel column 210 / bearing platform 200. This is because after the load is applied, the concrete floor will deform, but the stable connection structure between the bearing platform 200 and the steel bar binding layer restricts the occurrence of deformation of the concrete floor. Under the interaction, the load forces the concrete floor to generate cracks at the connection of the steel column 210 / bearing platform 200, resulting in quality defects; on the other hand, the stable connection structure between the bearing platform 200 and the steel bar binding layer in the prior art also makes it impossible to achieve seam division, that is, it is impossible to solve the crack problem at the concrete floor and the bearing platform 200 / steel column 210 Summary of the Utility Model
[0003] In order to solve the above problems of the prior art, the utility model provides a floor slab ground bearing platform steel column joint structure.
[0004] In order to achieve the above object, the main technical solutions adopted by the utility model include:
[0005] A floor slab ground bearing platform steel column joint structure, including a template arranged in a ring around the bearing platform; an inner pouring area is formed inside the template, and an outer pouring area is formed outside the template; the bottom of the bearing platform is connected to a first steel bar binding layer; the template is arranged on the first steel bar binding layer; a second steel bar binding layer is laid on the first steel bar binding layer; the second steel bar binding layer is arranged in the outer pouring area.
[0006] Further, the distance between the template and the bearing platform is 100-200mm.
[0007] Further, the template is formed by welding 430 flat steel.
[0008] Further, a plurality of reserved holes are provided on the template; a force transfer rod that is located in both the inner pouring area and the outer pouring area is arranged in the reserved holes.
[0009] Further, the force transfer rod is a force transfer steel bar.
[0010] Further, the first steel bar binding layer is laid throughout and penetrates through the bottom of the bearing platform.
[0011] Further, the first steel bar binding layer is arranged on the floor slab.
[0012] Further, a first concrete layer, a first fiber mesh layer, a second concrete layer, a second fiber mesh layer, and a surface layer are sequentially arranged from bottom to top on the top of the second steel bar binding layer.
[0013] Further, a steel column is connected to the top of the bearing platform.
[0014] The beneficial effect of the utility model is that the cap and the first concrete floor and the second concrete floor form a relatively independent structure through the split structure. The cap usually does not sink in the structure and the structure is stable. However, the concrete floor after the floor deck is cast has a certain flexibility and will deform when subjected to a large load, which may be settlement or bending deformation. In the existing traditional process, since the first steel bar binding layer and the second steel bar binding layer are both laid with through bars, they penetrate the cap and are integrally connected with the cap. The cap, as a fixed structure, keeps pulling the outer concrete floor to prevent it from deforming. The deformation stress of the concrete floor has nowhere to be released and cracks will be formed in the circumferential direction of the cap / steel column. The utility model changes the laying method of a layer of steel bar binding layer to prevent it from penetrating the cap to form a partition structure. The deformation / settlement of the second concrete floor can be independent of the cap, and the gap caused by the template is used to release the stress, that is, the split between the cap steel column and the concrete floor is completed, the problems of hollowing, warping and cracking are avoided, and the safety of the engineering structure is also guaranteed.

[0023] For the embodiments, please refer to Figure 2-3 as shown in
[0024] A floor slab ground bearing platform steel column joint structure, including a template 100 arranged in a ring around the bearing platform 200; an internal pouring area 120 is formed inside the template 100, and an external pouring area 130 is formed outside the template 100; the bottom of the bearing platform 200 is connected to the first steel bar binding layer 310, and a steel column 210 is connected to the top of the bearing platform 200; the template 100 is arranged on the first steel bar binding layer 310; a second steel bar binding layer 320 is laid on the first steel bar binding layer 310; the second steel bar binding layer 320 is arranged in the external pouring area 130; the first steel bar binding layer 310 is arranged on the floor slab 300; the first steel bar binding layer 310 is laid throughout and penetrates through the bottom of the bearing platform 200;
[0025] The template 100 is usually formed by welding 430 flat steel and is arranged around the bearing platform 200 in a surrounding form. The interfaces after enclosure can be welded or fixedly connected through bolt structures to form a surrounding structure, forming the internal pouring area 120 between the bearing platform 200 and the template 100 and the external pouring area outside the template 100; the shape of the template 100 can be prefabricated according to the shape of the bearing platform 200, as long as the internal pouring area 120 has a certain width, and the shape of the template 100 is not limited; in an embodiment, the bearing platform 200 is rectangular, and the template 100 is arranged around the bearing platform 200 in the shape of a rounded rectangle as Figure 2 shown in; the distance between the template 100 and the bearing platform 200 is 100-200mm. The distance between the template 100 and the bearing platform 200 refers to the distance from one side of the template 100 to the opposite surface of the bearing platform 200, as Figure 3 shown in H; the spacing can be evenly arranged or unevenly arranged. Usually, during construction, it only needs to ensure that the minimum spacing is greater than 100mm;
[0026] The template 100 is laid on the first steel bar binding layer 310, and the second steel bar binding layer 320 is arranged in the external pouring area 130. That is, by setting the template 100, the second steel bar binding layer 320 is not in direct contact with the bearing platform 200, and the second steel bar binding layer 320 is laid around the template 100; through this structural setting, after the pouring is completed, two relatively independent structural areas are formed outside the bearing platform 200, that is, the internal pouring area 120 and the external pouring area 130 separated by the template 100. The ground structure formed by the internal pouring area 120 is defined as the first concrete ground 121, and the ground structure formed by the external pouring area 130 is defined as the second concrete ground 131;
[0027] When the completed concrete floor (usually referring to the second concrete floor 131) bears an external load, the second concrete floor 131 will be deformed under pressure. There will be a gap between the first concrete floor 121 and the second concrete floor 131 separated by the formwork 100. This gap can allow the occurrence of deformation, thus avoiding the cracking of concrete caused by the inability to release the deformation. At the same time, the second steel bar binding layer 320 does not have continuous reinforcement running through the bearing platform 200. As a fixed structure, the bearing platform 200 will not prevent the deformation of the second concrete floor 131, enabling the deformation of the second concrete layer 350 to be released. By retaining the connection structure between the first steel bar binding layer 310 and the bearing platform 200, the effect of resisting bending can be achieved by using the first steel bar binding layer 310. The through-steel connection structure with the bearing platform 200 can also enhance the integrity of the overall concrete floor, making the concrete floor have a greater load-bearing capacity.
[0028] Through the jointing structure of the present utility model, the bearing platform 200 forms a relatively independent structure with the first concrete floor 121 and the second concrete floor 131. The bearing platform 200 usually does not settle in the structure and is stable. However, the concrete floor after the casting of the floor slab 300 has a certain flexibility and will deform when bearing a large load, which may be settlement or bending deformation. In the existing traditional process, since both the first steel bar binding layer 310 and the second steel bar binding layer 320 are laid with continuous reinforcement and penetrate through the bearing platform 200 and are integrally connected to the bearing platform 200, the bearing platform 200, as a fixed structure, always pulls the surrounding concrete floor to prevent it from deforming. The deformation stress of the concrete floor has nowhere to be released, and cracks will form in the circumferential direction of the bearing platform 200 / steel column 210. The present utility model changes the laying method of one layer of the steel bar binding layer to avoid its penetration through the bearing platform 200 and form a partition structure. The deformation / settlement of the second concrete floor 131 can be independent of the bearing platform 200, and the stress can be released by using the gap caused by the formwork 100, that is, the jointing between the bearing platform 200, the steel column 210 and the concrete floor is completed, avoiding problems such as hollowing, edge lifting and cracking, and ensuring the safety of the engineering structure.
[0029] In an embodiment of the present utility model, a plurality of reserved holes 101 are provided on the formwork 100, and a load transfer bar 110 located in both the inner casting area 120 and the outer casting area 130 is provided in the reserved holes 101; the load transfer bar 110 is a load transfer steel bar. By setting the load transfer steel bar, the transfer of the vertical load between the first concrete floor 121 and the second concrete floor 131 can be increased, and the edge lifting of the second concrete floor 131 can be avoided when it bears a load.
[0030] In an embodiment of the present utility model, a first concrete layer 330, a first fiber mesh layer 340, a second concrete layer 350, a second fiber mesh layer 360, and a surface layer 370 are sequentially provided from bottom to top on the top of the second steel bar binding layer 320; in an embodiment, at least one concrete layer is provided on the second steel bar binding layer 320, and the concrete structure provided on the second steel bar binding layer 320 can be adjusted according to actual engineering needs, which all fall within the protection scope of the present utility model.
[0031] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in the relevant technical fields, shall similarly be included in the patent protection scope of the present utility model.
