Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a supporting connector for concrete floor slabs. 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 bottom surface. This prevents the cage from being exposed, thereby increasing pouring strength and reducing the likelihood of oxidation from contact with air. Furthermore, welding tension bars (e.g., the triangular-shaped combined steel bars 103 in prior art CN117166662B and the steel truss 3 in prior art CN108661225B) is required above the cage. These tension bars act as a bending-resistance barrier during the lifting of the concrete slab, ensuring that the lifting process does not result in bending damage to the concrete slab itself. However, these tension bars are all made of steel and welded in a large amount. This requires manual or machine welding, resulting in high manufacturing costs and a high consumption of consumable steel. This wastes manpower and material resources, and does not meet national energy conservation and emission reduction requirements.

[0003] In summary, conventional concrete slabs use ordinary supports to support the steel cage, which has a simple structure. However, in order to match the ordinary supports, a lifting steel bar structure must be used to lift the concrete slab, resulting in a significant increase in overall steel consumption. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a supporting connector for a concrete floor slab, so as to solve the problem that the concrete floor slab uses ordinary supporting members to support the steel cage, resulting in the waste of consumables caused by the need to use a lifting steel bar structure.

[0005] In order to solve the above technical problems, the utility model provides a support connector for concrete floor slabs, which includes a base, a bend structure, a lifting rod and a quick-connect structure from bottom to top, wherein the base is located at the bottom, the bend structure is hook-shaped, the lower part of the bend structure is connected to the base, the lifting rod is connected to the upper part of the bend structure, and is arranged vertically; the quick-connect structure is located at the top of the lifting rod.

[0006] The supporting connector adopts an integrated structure, or is formed by connecting between the bending structure and the lifting rod.

[0007] The bottom surface of the base is a plane.

[0008] The bottom surface of the base is configured as a suction cup structure.

Alternatively, the return bend structure is C-shaped, with an opening facing horizontally and a concave structure at the bottom, and the concave structure is located directly above the base.

[0010] The outer wall of the lower part of the lifting rod is a threaded wall or an annular structure, and the outer diameter of the lower part is greater than the outer diameter of the upper part.

[0011] The outer wall of the upper portion of the lifting rod is provided with a scale structure.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] like Figure 1As shown, the present invention provides a support connector for concrete floor slabs. It adopts an integrated structure and comprises, from bottom to top, a base 11, a bend structure 12, a lifting rod 13, and a quick-connect structure 14. The base 11 is located at the bottom, the bend structure 12 is hook-shaped, and the lower portion of the bend structure 12 is connected to the base 11. The lifting rod 13 is connected to the upper portion of the bend structure 12 and arranged vertically. The quick-connect structure 14 is located on top of the lifting rod 13. The base 11 is used to support the ground and determine the support position; the bend structure 12 is used to store and support steel bars; the lifting rod 13 is used to lift the steel bars upward after casting. The quick-connect structure 14 can be connected to an external clamping structure to serve as a direct load-bearing structure.

[0030] The support connector for concrete floor provided by the utility model is formed by integral injection molding or welding molding, so that the overall tensile strength is good, it can bear heavy objects, and maintain the stability of the support connector itself without being easily deformed.

[0031] The base 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.

[0032] The bottom surface of the base 11 is flat and generally circular, so that it can better contact the ground and provide stable support.

[0033] The bottom surface of the base 11 is configured as a suction cup structure, and the suction cup can be adsorbed on the ground, thereby maintaining the position of the base 11 and preventing it from moving easily.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] like Figure 3As 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.

[0038] 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. This allows the lifting rod to better bond with the concrete layer, providing greater support during the lifting process and preventing the lifting rod 13 from slipping off the concrete layer.

[0039] 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.

[0040] The outer wall of the upper portion of the lifting rod 13 is provided with a scale structure 132 , which enables the pouring construction workers to know the pouring thickness, so as to better adjust the pouring thickness.

[0041] The quick-connect structure 14 is a T-shaped block, an inverted trapezoidal structure, or a structure with holes.

[0042] The opening of the return-bend structure 12 is located at the upper side, and the bottom of the groove inside the return-bend structure is located directly above the base.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.
