Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a portable and lifting concrete floor slab. Background Art

[0002] During the pouring of concrete slabs (prestressed concrete thin-slab composite slabs), a steel cage must be secured. The cage's lower portion is typically supported by supports, leaving a pouring space between the cage and the pouring floor. This prevents the cage from being exposed, thereby increasing pouring strength and reducing the likelihood of oxidation from air contact. Furthermore, a top portion of the cage must be welded with tensioning bars (e.g., the triangular-shaped combined steel bars 103 in prior art CN117166662B and the steel truss 3 in prior art CN108661225B). These tensioning bars act as a bending-resistance barrier during the lifting of the concrete slab, ensuring that the lifting process does not cause bending damage to the concrete slab itself. However, these tensioning bars are all made of steel and welded, requiring a large amount of steel and requiring manual or machine welding. This results in high manufacturing costs and a high consumption of consumable steel, leading to a waste of manpower and material resources.

[0003] In summary, existing concrete slabs utilize conventional supports to support the steel cage, which has a simple structure. The tensioning steel bars used must be welded to the cage, making them difficult to secure during the pull process. Furthermore, the steel is wasted (typically accounting for approximately 20% of the total steel consumption), thus failing to meet energy conservation and environmental protection requirements.

[0031] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figure 5-6 As shown, the concrete floor provided by the present invention includes a concrete layer 20, a steel cage 30 cast in the concrete layer 20, and a plurality of support connectors 10. The plurality of support connectors 10 are arranged in a matrix manner and cast in the concrete layer 20. The steel cage 30 is laterally supported in the bend structure 12 of the support connector 10, and the quick-connect structure 14 of the support connector 10 is on the upper part of the concrete layer 20.

[0035] The portable lifting concrete floor provided by the utility model casts the supporting connector in the concrete layer, and places the quick-connect structure of the supporting connector on the upper part of the concrete layer, so that it is convenient for external tools to clamp and lift the concrete floor, thereby completely saving the material cost of pulling steel bars, and the quick-connect structure can quickly connect external structural members, which can facilitate the lifting of the concrete floor.

[0036] like Figure 1-4 As shown, the supporting connector 10 adopts an integrated structure, which includes a base 11, a bend structure 12, a lifting rod 13 and a quick-connect structure 14 from bottom to top. The base 11 is located at the bottom, the bend structure 12 is hook-shaped, and the lower part of the bend structure 12 is connected to the base 11. The lifting rod 13 is connected to the upper part of the bend structure 12 and is arranged vertically. The quick-connect structure 14 is located on the top of the lifting rod 13. The upper parts of the quick-connect structure and the lifting rod are located outside the concrete layer, protruding upright from the upper surface of the concrete layer, and the height of the quick-connect structures of all supporting connectors is the same. The base 11 is used to support the ground and determine the support position; the bend structure 12 is used to receive and support the steel bars, the lifting rod 13 is used to pull upward after casting, and the quick-connect structure 14 can be connected to the external clamping structure to serve as a direct load-bearing structure.

[0037] The supporting connector 10 is formed by integral injection molding or welding, so that the overall tensile strength is good, it can bear heavy objects, and maintain the stability of the supporting connector itself without being easily deformed.

[0038] The base 11 is used to support the ground and provide supporting force for the entire supporting connector. The base and the bend structure together determine the height of the supporting steel bars, thereby determining the distance between the steel bars and the ground.

[0039] The bottom surface of the base 11 is flat and is located in the same plane as the bottom surface of the concrete layer. The bottom surface is usually circular, so that it can better contact with the ground and provide stable support.

[0040] The bottom surface of the base 11 is configured as a suction cup structure to maintain adsorption with the ground during concrete pouring, so that the concrete slurry does not enter the suction cup structure. The suction cup can be adsorbed on the ground, thereby maintaining the position of the base 11 and preventing it from moving easily.

[0041] The lifting rod 13 and the base 11 are located on the same vertical axis. The lifting rod 13 withstands the upward tension, thereby lifting the concrete floor slab through the tight connection force between the lifting rod 13 and the concrete. The placement of the lifting rod 13 and the base 11 on the same vertical axis also makes installation of the entire support connector easier and prevents the problem of sideways tilt.

[0042] like Figure 2 As shown, the bending structure 13 is U-shaped, and the lifting rod 13 is connected to one side of the bending structure. At this time, the bottom of the bending structure 13 is located directly above the base, so that the bending structure 13 can directly transmit the pressure of the steel bar downward after bearing it, avoiding the tilting of the supporting connection.

[0043] like Figure 4 As shown, the bending structure 13 is L-shaped, the lifting rod is connected to the vertical side of the bending structure, the corner position of the bending structure is concave, and the other side extends horizontally, and the concave part is located directly above the base.

[0044] like Figure 3 As shown, the bent structure 13 is C-shaped, with an opening facing horizontally, and a concave structure at the bottom, which is located directly above the base.

[0045] The outer wall of the lower portion of the lifting rod 13 is a threaded wall or annular structure 131, and the outer diameter of the lower portion is larger than the outer diameter of the upper portion. The lower portion of the lifting rod is located in the concrete layer. This ensures a better bond between the lifting rod and the concrete layer, provides greater support during the lifting process, and prevents the lifting rod 13 from slipping off the concrete layer.

[0046] The lifting rod can also be configured as an integral conical column structure, with the lower end of the conical column being larger than the upper end.

[0047] The outer wall of the upper part of the lifting rod 13 is provided with a scale structure 132, at least a part of which reveals the concrete layer. The scale structure enables the pouring construction workers to know the pouring thickness, so that they can better calculate the pouring thickness.

[0048] The quick-connect structure 14 is a T-shaped block, an inverted trapezoidal structure or a structure with a hole. The external lifting device can be designed to clamp the T-shaped block, the inverted trapezoidal structure, or can pass through the hole to connect the quick-connect structure.

[0049] The opening of the return-bend structure 12 is at the upper side, the bottom of the groove inside the return-bend structure is located directly above the base, and the return-bend structure 12 is cast in the concrete layer 20 as a whole.

[0050] The supporting connector is made of an inorganic material that resists tensile strength, thereby reducing weight and avoiding the use of steel bar materials, thereby saving costs.

[0051] The supporting connector is made of nylon, plastic, rubber or a combination thereof. For example, the lifting rod 13 can be made of tensile-resistant nylon, the base and the return bending structure can be made of plastic or rubber, and then the lifting rod and the return bending structure can be connected together.

[0052] The support connector for concrete floor slabs provided by the utility model is supported on the ground by a base, and is supported by aligning steel bars by accommodating the steel bars through a bend structure, and is connected with an external lifting device through a lifting rod and a quick-connect structure thereon, so that the support connector can be cast in the concrete after the concrete floor slab is cast and formed; when the concrete floor slab needs to be lifted, the entire concrete floor slab can be lifted and moved by simply clamping the quick-connect structure through an external lifting device; compared with the concrete floor slabs using a lifting steel bar structure in the prior art, all lifting steel bar materials can be saved, and the supporting structure is stable.

[0053] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
