Description
Technical Field
[0001] The utility model relates to the technical field of floor slabs, in particular to a floor joint structure for floor slabs supported by steel decks. Background Art
[0002] For floor slabs supported by steel decks, continuous steel bars are usually laid and then concrete is poured to form an integral floor structure. This structure is often used in the construction of large-area factories. The area of the integral concrete floor can reach 2000 - 3000 square meters. Due to the continuous laying of steel bars, it is impossible to make joints in this large-area concrete integral floor structure. There is a high probability of cracks occurring during later use, and the quality risk is high, affecting the use. If the form of block-by-block pouring is adopted, there will be a problem that it is difficult to perforate the steel bars between adjacent two concrete floors. In the prior art, the cutting joint treatment for large-area pouring of concrete floors is not applicable to the floor slabs supported by steel decks either. The steel bars continuously laid between the floor slabs supported by steel decks will break after cutting joints, which will affect the stress and structural strength of the concrete floor. Content of the Utility Model

[0024] For the embodiments, please refer to Figure 1 as shown in
[0025] A floor slab joint structure on the ground, comprising a template 100 connected to a floor slab 401; the template 100 is usually made of 430 flat steel, has a certain structural strength, and is convenient for processing into a prefabricated template 100 structure; the template 100 is vertically arranged and used to separate the concrete floors on both sides. By setting the template 100, when pouring a large area of the site, the large area of the site can be divided into multiple small sites for processing. For example, a 3000-square-meter floor slab 401 space to be poured can be divided into three areas, each with a space of 1000 square meters, by using two long templates 100, and then construction can be carried out;
[0026] The setting of the template 100 enables the steel bars to be tied in adjacent spaces without laying continuous steel bars. Instead, the steel bar tying layers are laid separately in the separated areas. The force transmission between adjacent concrete floors is realized through the force transmission bars 300 and the anchor fittings 200. Since the force transmission bars 300 and the anchor fittings 200 can be prefabricated, and the joint structure of the present invention is installed before pouring, the problem of difficult steel bar perforation is solved, and effective force transmission between the plates is ensured;
[0027] In an embodiment, the anchor fittings 200 are usually arranged on one side of the template 100, and the anchor fittings 200 extend along the length direction of the template 100, that is, the anchor fittings 200 have a certain length in the length direction of the template 100. The anchor fittings 200 can be in a long strip structure and have the same length as the template 100, so as to have strong anchoring performance; they can also be arranged at intervals, and the anchoring effect can also be achieved; a plurality of force transmission bars 300 are arranged at intervals along the length direction of the template 100 on the template 100; at least one end of the force transmission bar 300 extends out of the template 100; see Figure 1 , only the concrete floor on the left side is shown (the concrete floor structure on the right side is the same). In this structure, during actual construction, the right side of the template 100 also has a concrete floor. Both ends of the force transmission bar 300 extend out of the template 100. The force transmission bar 300 is usually a force transmission steel bar, and its two ends act on one concrete floor each, so as to realize the vertical load and horizontal load transmission between two adjacent concrete floors, and can strengthen the structural strength at the joint structure caused by the template 100, and there will be no phenomena such as hollowing, edge warping, and cracking due to the thin concrete layer, insufficient strength, or grade; in an embodiment, the force transmission steel bar is arranged below the anchor fitting 200;
[0028] Since the anchor 200 is connected to the connecting part 210, and the connecting part 210 is connected to the floor slab 401, the anchor 200 can provide strong anchoring ability to the concrete floor, avoiding the problems of hollowing or edge lifting here. The anchoring ability of the anchor 200 to the left concrete floor can be transmitted to the right concrete floor (not shown in the figure) through the load transfer bar 300, realizing the force transfer between the two sides of the concrete floor. Therefore, the anchor 200 can be provided only on one side of the formwork 100; in another embodiment, the anchor 200 can also be provided on both sides of the formwork 100, but the cost will be increased accordingly;
[0029] In one embodiment, one end of the load transfer bar 300 extends out of the outside of the formwork 100, as Figure 2 shown. The load transfer bar 300 only extends out towards one side of the concrete floor. At this time, the joint structure is applied to the outermost edge of the concrete floor. At this time, the function of the load transfer bar 300 is different from that of the previous embodiment. In this embodiment, the function of the load transfer bar 300 is the same as that of the anchor 200, both of which are used to strengthen the anchoring ability between the concrete floor and the floor slab 401, avoiding the occurrence of edge lifting or hollowing;
[0030] The formwork 100 is usually a flat sheet-like long structure, made of metal material, with a relatively flat plane. It is applied between the concrete floors for partitioning. The end face of the formwork 100 itself is not a very stable fixed connection structure with the concrete floor. After construction, a small gap will be formed naturally, specifically as Figure 1 shown. A small gap will be formed between the flat end face on the right side of the formwork 100 and the concrete floor on the right side (not shown), so as to adapt to the deformation of the concrete floor under the action of shrinkage / expansion stress and avoid cracking;
[0031] In one embodiment, the formwork 100 includes a vertical part 110 and a support part 120 connected to the bottom of the vertical part 110; the support part 120 is connected to the floor slab 401; the support part 120 is arranged parallel to the floor slab 401; by adding the support part 120, on the one hand, it is convenient to fix the formwork 100 and the floor slab 401, and on the other hand, it can strengthen the strength and stability of the connection, providing a stable connection structure for the anchoring of the concrete floor;
[0032] In one embodiment, the anchor 200 includes a connecting portion 210 fixedly connected to the formwork 100; the connecting portion 210 extends away from the formwork 100 to form a first stress-bearing portion 220; a plurality of through holes 240 are provided at intervals along the length direction of the first stress-bearing portion 220 on the first stress-bearing portion 220; the connecting portion 210 is preferably surface-connected to the formwork 100, so that the two have more contact surfaces and the connection is more stable; the connecting portion 210 can be welded to the end face of the formwork 100 with the same 430 flat steel; in another embodiment, the connecting portion 210 can also be the edge end face of the first stress-bearing portion 220; the length direction of the first stress-bearing portion 220, such as Figure 3 the up and down direction in, the length direction of the first stress-bearing portion 220 is consistent with the length direction of the formwork 100; after the through holes 240 are provided, when the concrete floor is poured, the concrete passing through the through holes 240 can achieve a stronger anchoring connection with the first stress-bearing portion 220;
[0033] In one embodiment, a second stress-bearing portion 230 is provided at one end of the first stress-bearing portion 220 away from the connecting portion 210, and the second stress-bearing portion 230 is arranged at an angle to the first stress-bearing portion 220; the second stress-bearing portion 230 is used to further enhance the anchoring performance of the anchor 200 with the concrete floor; the second stress-bearing portion 230 can extend downward as Figure 1 in; in another embodiment, it can also extend upward;
[0034] In one embodiment, the length of the anchor 200 is the same as the length of the formwork 100; the anchor 200 is arranged in a long strip shape. In addition to enhancing the anchoring ability of the combination with the concrete floor, it can also increase the structural strength of the concrete and prevent the concrete floor from bulging and cracking along the length direction of the formwork 100;
[0035] In one embodiment, the concrete floor is arranged above the floor slab 401; the concrete floor includes a first steel bar binding layer 402, a first concrete layer 403, a second steel bar binding layer 405, and a surface layer 406 from bottom to top.
[0036] In one embodiment, the concrete floor is arranged above the floor slab 401; the concrete floor includes a first steel bar binding layer 402, a first concrete layer 403, a second concrete layer 404, a second steel bar binding layer 405, and a surface layer 406 from bottom to top; that is to say, the concrete layer can be arranged in multiple layers and can be appropriately adjusted according to the actual required height of the floor; the above composition structure of the concrete floor is also a common structure for the floor of the floor slab 401, which can provide sufficient strength and durability for the floor of the floor slab 401; the thickness of the concrete floor is usually 120mm - 180mm.
[0037] The above are only 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 related technical fields, shall similarly be included within the patent protection scope of the present utility model.
