Modular Prefabricated Rebar Component

Abstract

The present invention relates to a novel form of modular prefabricated rebar component that relates generally to building construction, and particularly to an improvement in reinforced concrete with modular prefabricated rebar components.

Claims

1. A modular prefabricated rebar component comprising: as per claim 1, a vertical and horizontal reinforced steel bars welded together; as per claim 1, a reinforced steel stirrups welded onto the above steel bars; as per claim 1, a steel chairs and hangers welded onto the reinforced steel bars; as per claim 1, a steel concrete pour stop welded onto the reinforced steel bars, and, as per claim 1, a plastic mechanical sleeves welded with steel rings onto the reinforced steel bars.

2. A modular prefabricated rebar component allowing all reinforced concrete components for foundation and superstructure of a building to be pre-fabricated in a manufacturing facility before delivery to the construction site. Upon delivery to the construction site, the modular components can be assembled like a jigsaw puzzle so that concrete can be poured and cured on them.

3. A novel form of rebar structure comprising: as per claim 1, a self-locking rebar coupler; as per claim 1, a vertical piece of rebar; as per claim 1, a rebar stirrup welded in place during manufacturing; as per claim 1, a rebar chair welded in place during manufacturing; and, as per claim 1, a column after concrete is poured and cured.

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views, together with the detailed description below, are incorporated in and form part of the specification, and serve to further illustrate embodiments of concepts that include the claimed invention, and explain various principles and advantages of those embodiments.

[0040] FIG. 1 shows the complete component view of the present invention.

[0041] FIG. 2 shows the isometric view of the proposed assembly as per preferred embodiments of the invention.

[0042] FIG. 3 shows another view as per preferred embodiments of the invention.

[0043] FIG. 4 shows all the components of the invention as used in an elevator pit, elevator pit foundation wall, and adjoining mat floor slab per preferred embodiments of the invention.

[0044] Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the present invention.

[0045] The apparatus and method components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.

DETAILED DESCRIPTION

[0046] Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

[0047] The present invention relates to an advancement in modular prefabricated rebar components. As used herein, the term rebar refers to a length of metal bar, often steel, which is placed into formwork before concrete is poured around it. It shall be understood that rebar is available in many grades and diameters.

[0048] The present invention as per its preferred embodiments provide a reinforcing bar component that combines rebar pieces during manufacturing that are significantly lighter than the rebar cages currently available, and are capable of easy, fast, strong installation that can stably handle loads as well as tensile and compressive forces. The present invention has the follow features for achieving the above object.

[0049] The present invention as per its additional embodiments eliminates the need for additional heavy equipment for delivering, bending, and installing reinforcing bars during manufacturing and on the construction site as compared with the background art, and can reduce construction cost and can save time required for construction.

[0050] The assembly as per its additional embodiments makes it possible to rapidly install rebar since the prefabricated rebar components are much lighter to move around a construction site than heavy crane delivered rebar cages, are fully pre-fabricated off site and then lock together using a self-locking rebar coupler.

[0051] The assembly as per its additional embodiments, make it possible to construct all foundation and superstructure elements by having all of the reinforcing bars delivered pre-fabricated to the construction site and able to be installed without requiring welding, tying, clamping, or lap splicing.

[0052] The assembly as per its additional embodiments allows all elements required for the concrete pour to be pre-fabricated in a modular way to reduce human error on site and ease speed with which concrete can be being poured onto the rebar for curing.

[0053] Having described the invention in detail, those skilled in the art will appreciate that modifications may be made to the invention without departing from its spirit. Therefore, it is not intended that the scope of the invention be limited to the specific embodiment illustrated and described. Rather, it is intended that the scope of this invention be determined by the appended claims and their equivalents.

[0054] The Abstract of the Disclosure is provided to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separately claimed subject matter.
