Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

Embodiments of the invention relate generally to structural framing systems. More particularly, embodiments of the invention relate to a foldable steel structural framing system that can reduce on-site framing time.

2. Description of Prior Art and Related Information

The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.
As the population grows, the demand for housing is increasing. To adapt to this change, solutions are sought out as to how to improve traditional construction methods by making the way houses are built modular and simple, thus increasing the speed of construction. In the traditional construction method, framing is a required process, but can prove both time-consuming and laborious.
Conventional basic framing structure includes a sole plate and a top plate with wall studs spanning therebetween. Typically, this structure is built on-site with wood or steel structural elements. This requires substantial on-site labor to erect such a framing structure. Further, such framing may be performed before the outer envelope of the structure is complete, subjecting the materials and builders to the environment during the laborious construction process.
In view of the foregoing, there is a need for an improved framing process that can reduce required on-site labor time in constructing a building frame.

A commercial implementation in accordance with the spirit and teachings of the present invention may be configured according to the needs of the particular application, whereby any aspect(s), feature(s), function(s), result(s), component(s), approach(es), or step(s) of the teachings related to any described embodiment of the present invention may be suitably omitted, included, adapted, mixed and matched, or improved and/or optimized by those skilled in the art, using their average skills and known techniques, to achieve the desired implementation that addresses the needs of the particular application.
Broadly, embodiments of the present invention provide a mechanically foldable frame for a steel structure framing process. Since the framing process costs a lot of time in the house building process, a foldable steel structure can realize fast framing. The foldable frame structure includes beams and columns can be folded into flat frames for transportation. The foldable frame structure can save on-site operation time by replacing the framing process with factory-made mechanical equipment.
FIG. 1A illustrates the final view of an assembled steel structure building frame 100. A four-level apartment has been taken as an example introduced herein. FIG. 1B shows a top view of the building frame 100 which looks like six square frames. This structure provides 26 thin columns on each floor. These columns can be enough to support the loading above. Further, in this embodiment, there are 17 primary beams for each floor. These beams can support the loading of the next floor. The beams and columns are designed as smaller features and combined to be enough for loading requirements. Bearing parts are distributed as shown, and leave a lot of space for diving rooms. The beams may span various lengths from its pivoting attachment end to its opposite end. For example, the beams may span distances of 8 feet, 10 feet, 12 feet, 16 feet, 24 feet, or 30 feet, as examples. The length may be determined by load characteristics, desired room configuration, or the like. Similarly, the height of the columns 204 may vary, depending on application. For example, column lengths of 8 feet, 10 feet, 12 feet or longer may be used. In some embodiments, the column length can be 10 feet and the beam length can also be 10 feet. Additional, non-load bearing walls may be added within the structure provided by the frame 100.
FIG. 2A illustrates a single piece of a middle part foldable steel structure frame 200 (also referred to simply as middle part 200). After it has been expanded, the middle part 200 becomes an H shape. The H-shape structure has relatively high stability. The middle part 200 can include beams 202, columns 204 and end studs 206. The beams 202 can attach to columns 204 with a pivoting connection to permit the folding of the middle part 200. Where a column 204A has two pivoting beams 202 and one non-pivoting beam 202A, the non-pivoting beam 202A may be fixed to the column 204A by means known in the art, including fasteners, welding, or the like.
FIG. 2B illustrates an end frame part 210. After several middle part frames 202 have been set up, the end frame part 210 can be used to create the boundary of the building. Two sides will both use the end frame part 210 to make the edge. The end frame part 210 can have a similar design as the middle part 200, with beams 202 pivotably attached to columns 204. In some embodiments, end columns 208 may only include a shoulder 400/protrusion 401/spindle 404 (see FIGS. 4A through 4C) on one side thereof to form a flush exterior side, as can be seen in FIG. 2B. In some embodiments, the end of the beam 202 that connects to the end columns 208 may be fixed to the end columns 208 by various manners, such as fasteners, welding, or the like.
FIGS. 3A and 3B show folded configurations for the foldable steel structure frame. FIG. 3A is for the H-shape middle part frame 200 and FIG. 3B is for the end frame part 210. The flat piece of structure frame saves space by transferring a 3D shape into a 2D shape. FIGS. 3C and 3D illustrate the folding process of the middle part frame 200. There are totally six beams 202 and seven columns 204 in one middle part frame 200. The mid column serves as an axis. Two beams connected to it can rotate around the mid column. Then beams on the most outside can also rotate around two side columns. The mid column and side columns are designed for folding features. And there are four edge columns used to keep the structural integrity located at the end of the side beams.
FIGS. 4A through 4C illustrate an exemplary column 204 according to an embodiment of the present invention. The column 204 can be a hollow column with spindles 404 which provide a pivot axis for the beams. At the top of the beam, there is an extended platform 400 for beams. The platform 400 and the hollow column have a Y-shape connection so that the load from the beam will be guided to the column. There are spindles 404 at the bottom of the column as well that are disposed in a protrusion 401 from the axis of the column 204. These spindles 404 are for bottom beam connections and the bottom beams can rotate around the column as illustrated above in the folding of the middle part 200.
The spindles 404 may be disposed on an opening 402 in the platform 400 such that there is a space entirely about the spindle 404. The beams may be attached to the spindles by various manners. In some embodiments, the beams may be placed in position and the spindles 404 may be inserted from a top end of the column 204, for example. In some embodiments, the top of the columns may be removable to permit access to the spindle 404. Once the beam is attached, the top cover can be placed on top to block the spindle. In some embodiments, the top cover may also block the opening 402 after assembly.
FIGS. 5A through 5C illustrate an exemplary beam 202 used in this invention. The beam can be formed, for example, as an I-shape beam. The beam can be attached to the hollow column as shown. The I-shape beam can fulfill the requirement of loading at the same time rotating around the column. The beam 202 can include a pivot end 500 and an attachment end 504. The pivot end 500 can include a pivot opening 502 through which the spindle 404 (see FIGS. 4A through 4C) can extend.
FIG. 6 introduced an optional stopper mechanism that can be used in embodiments of the present invention. The stopper mechanism can be added into the beam for locking it to a specific position. The axis on the spindle 404 of the column 204 can be cut by a square shape 602 and a similar geometric shape 604 cab be cut on the spindle opening 600 of the beam 202. After that, a blocker 606, supported with springs 608, can fill these cutouts 602, 604. The spring 608 can be squeezed until the beam 202 rotates to desired position. Then, the spring 608 can push the blocker 606 out and lock the beam 202 to form a stable structure.
