Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. application Ser. No. 15/929,909, filed May 28, 2020, which claims the benefit of U.S. Provisional Application Ser. No. 62/855,416, filed on May 31, 2019.

FIELD OF THE INVENTION

The present invention relates generally to the field of multistory building construction and, more particularly, to systems and methods for the construction of multistory buildings utilizing a unique post-fit telescoping and non-telescoping support column system.

BACKGROUND OF THE INVENTION

Typically, multistory steel-framed buildings are constructed using vertical steel columns spanning the full height of the building. For buildings of only a few stories, each column is commonly provided in one piece. For buildings of more than a few stories, each column is commonly provided by multiple column members connected by welding and/or bolted plates with each column member spanning several floors. Intermediate floors are typically framed with horizontal beams attached to the columns by sheer tabs or welding. Joists and floor decking arc commonly installed on the horizontal beams.
While such basic construction systems generally provide a very strong vertical column, each such column member is typically quite long and, therefore, quite heavy. These long and heavy columns typically require lifting equipment to hoist them and place them in position or teams of laborers to accomplish these tasks. Lifting equipment, such as cranes or other mechanical hoisting devices, and teams of laborers add significant expenses to the typical construction project as well as adding coordination difficulties and time delays to the typical construction project.
Advances in the art of multistory building construction include the following:
U.S. Pat. No. 5,444,957 describes a method of erecting the frame of a multistory structure and constructing poured concrete floor slabs of a multistory structure. However, this method involves terminating the vertical support members just below the level of the finished floor slab and chipping away a portion of the finished floor slab to expose the vertical support member terminations.
U.S. Pat. No. 6,151,851 describes a stackable support column system and method for multistory building construction. However, this system involves the use of a cumbersome full first column or base column for attachment to the floor, and a base retainer attached to a lower portion of each column.
U.S. Pat. Appl. No. US 2005/0097844 describes a method and system of construction of a multistory building. However, this system involves the use of columns with an upper planar surface in which an aperture is centrally disposed. Columns for succeeding floors have a plate on a bottom surface thereof with an alignment pin extending therefrom for insertion into the aperture of the lower-floor columns.
U.S. Pat. Appl. No. US 2006/0010825 describes a method, building and system for constructing a multistory building. However, this system involves the use of a connector into which a lower-floor column and an upper-floor column slidingly fit and which connectors are fastened to the lower-floor and upper-floor columns.
U.S. Pat. Appl. No. US 2007/0079567 describes a method and system for constructing a multistory building. However, this system involves the use of a footing into which grout is placed and then a lower portion of a first-floor column is inserted into the footing. The first-floor column is fastened to the footing with self-tapping screws. An internal connector is partially inserted into the top of the first-floor column and into the bottom of an upper-floor column. The internal connector is fastened to the lower-floor and upper-floor columns.
U.S. Pat. Appl. No. US 2008/0053020 describes a method and system for constructing a multistory building. However, this system involves the use of a connector into which a lower-floor column and an upper-floor column slidingly fit and which connectors are bifurcated horizontally by a plate. A base plate telescopically receives the bottom end of the lowest-floor column.
A need exists for an alternative system and method for the construction of multistory buildings that may overcome the known shortcomings in the art.
While certain aspects of conventional technologies have been discussed to facilitate disclosure of the invention, the applicant in no way disclaims these technical aspects, and it is contemplated that the claimed invention may encompass one or more of the conventional technical aspects discussed herein. The present invention may address one or more of the problems and deficiencies of the advances in the art of multistory building construction discussed above. However, it is contemplated that the invention may prove useful in addressing other problems and deficiencies in a number of technical areas. Therefore, the claimed invention should not necessarily be construed as being limited to addressing any of the particular problems or deficiencies discussed herein or as being limited to the particular embodiment for the invention used to illustrate the steps and functionality of the herein disclosed invention.
This background information is provided to reveal information believed by the applicant to be of possible relevance to the present invention. No admission is necessarily intended, or should be construed, that any of the preceding information constitutes prior art against the present invention. This reference or discussion is not an admission that the document, act or item of knowledge, or any combination thereof, was at the priority date, publicly available, known to the public, part of common general knowledge, or otherwise constitutes prior art under the applicable statutory provisions; or is known to be relevant to an attempt to solve any problem with which this specification is concerned.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention arc shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments arc provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Those of ordinary skill in the art realize that the following descriptions of the embodiments of the present invention are illustrative and are not intended to be limiting in any way. Other embodiments of the present invention will readily suggest themselves to such skilled persons having the benefit of this disclosure. Like numbers refer to like elements throughout.
Although the following detailed description contains many specifics for the purposes of illustration, anyone of ordinary skill in the art will appreciate that many variations and alterations to the following details are within the scope of the invention. Accordingly, the following embodiments of the invention are set forth without any loss of generality to, and without imposing limitations upon, the claimed invention.
In this detailed description of the present invention, a person skilled in the art should note that directional terms, such as “above,” “below,” “upper, lower,” and other like terms are used for the convenience of the reader in reference to the drawings. Also, a person skilled in the art should notice this description may contain other terminology to convey position, orientation, and direction without departing from the principles of the present invention.
Furthermore, in this detailed description, a person skilled in the art should note that quantitative qualifying terms such as “generally,” “substantially,” “mostly,” and other terms are used, in general, to mean that the referred-to object, characteristic, or quality constitutes a majority of the subject of the reference.

Thus, specific embodiments are given for the purpose of simplified explanation and not for limitation.
An embodiment of the invention, as shown and described by the various figures and accompanying text, provides a multistory building construction system according to an embodiment of the present invention. The multistory building construction system may implement a system to construct a multistory building in a cost-effective, labor saving, and structurally sound manner.
Referring more specifically to FIGS. 1 and 2, the multistory building construction system 100, according to an embodiment of the present invention, will now be discussed. The system 100 may include at least one base plate 200, which may be positioned on a slab of a multistory building site according to engineering plans at a location suitable for carrying a load from at least one upper floor of the multistory building. The at least one base plate 200 may be fastened or affixed to the slab. The at least one base plate 200 may have or define a plurality of openings 210 disposed therein to permit the passage of a corresponding plurality of fasteners therethrough to secure the at least one base plate to the slab. The at least one base plate 200 may have a sleeve 220 (e.g., base sleeve) extending vertically or outwardly from a top surface thereof. The sleeve 220 may be welded to the top surface of the at least one base plate 200 along an interior seam between a bottom of the sleeve and the at least one base plate top surface.
The system 100 may also include at least one first-floor column 300 with a cross-sectional shape that is substantially similar to a cross-sectional shape of the sleeve 220. The at least one first-floor column 300 may be sized so that an interior dimension of the at least one first-floor column is slightly larger than an exterior dimension of the sleeve 220. The at least one first-floor column 300 may be configured to matingly engage with the sleeve 220 of the at least one base plate 200, so that the sleeve extends into a bottom end of the at least one first-floor column. The at least one first-floor column 300 may be adjusted on the at least one base plate 200 so as to be trued and plumbed and so as to achieve a desired height according to engineering plans to support the load from the at least one upper floor of the multistory building. The at least one first-floor column 300 may be affixed to the at least one base plate 200 by welding or by other suitable means according to engineering plans.
The at least one first-floor column 300 may have a cap plate 310 affixed to a top end thereof. The cap plate 310 may have a width consistent with a width of the at least one first-floor column 300. The cap plate 310 may have a lateral distance that is longer than a lateral distance of the at least one first-floor column 300. In one embodiment present invention, the lateral distance of the cap plate 310 is six inches (6″) greater than the lateral distance of the at least one first-floor column 300. The cap plate 310, according to one embodiment of the present invention, may be positioned on the top end of the at least one first-floor column 300 so that approximately three inches (3″) of the cap plate extends horizontally beyond a first side of the lateral distance of the at least one first-floor column and so that approximately three inches (3″) of the cap plate extends horizontally beyond an opposite second side of the lateral distance of the at least one first-floor column. The at least one first-floor column 300 may have at least one sheer tab 330 affixed to the width of the at least one first-floor column oriented vertically. The at least one sheer tab 330 may be configured to be affixed to an end of a beam. The at least one sheer tab 330 may be positioned so that when the beam is affixed thereto, the beam and the cap plate 310 may support a decking for a concrete floor. The at least one first-floor column 300 may have a sleeve 320 (e.g., first sleeve) affixed to a top surface of the cap plate 310 extending vertically and/or outwardly therefrom. The sleeve 320 may be welded to the top surface of the cap plate 310 along an exterior seam between a bottom of the sleeve and the cap plate top surface.
The system 100 may also include at least one second-floor column 400 with a cross-sectional shape that is substantially similar to a cross-sectional shape of the sleeve 320. The sleeve 320 may be sized so that an interior dimension of the sleeve is slightly larger than an exterior dimension of the at least one second-floor column 400. In one embodiment of the present invention, the exterior dimension of the at least one second-floor column 400 is substantially similar to an exterior dimension of the at least one first-floor column 300. In another embodiment of the present invention, the exterior dimension of the at least one second-floor column 400 is slightly less than the exterior dimension of the at least one first-floor column 300. The at least one second-floor column 400 may be configured to matingly engage with the sleeve 320, so that a bottom end of the at least one second-floor column extends into the sleeve. The at least one second-floor column 400 may be adjusted within the sleeve 320 so as to be trued and plumbed and so as to achieve a desired height according to engineering plans to support the load from a higher floor of the multistory building. The at least one second-floor column 400 may be affixed to the sleeve 320 by welding or by other suitable means according to engineering plans.
The at least one second-floor column 400 may have a cap plate 410 affixed to a top end thereof. The cap plate 410 may have a width consistent with a width of the at least one second-floor column 400. The cap plate 410 may have a length that is longer than a length at least one second-floor column 400. In one embodiment of the present invention, the length of the cap plate 410 is six inches (6″) longer than the length of the at least one second-floor column 400. The cap plate 410, according to one embodiment of the present invention, may be positioned on the top end of the at least one second-floor column 400 so that approximately three inches (3″) of the cap plate extends horizontally beyond a first side of the length of the at least one second-floor column and so that approximately three inches (3″) of the cap plate extends horizontally beyond an opposite second side of the length of the at least one second-floor column. The at least one second-floor column 400 may have at least one sheer tab 430 affixed to the width of the at least one second-floor column oriented vertically. The at least one sheer tab 430 may be configured to be affixed to an end of a beam. The at least one sheer tab 430 may be positioned so that when the beam is affixed thereto, the beam and the cap plate 410 may support a decking for a concrete floor. The at least one second-floor column 400 may have a sleeve 420 (e.g., second sleeve) affixed to a top surface of the cap plate 410 extending vertically and/or outwardly therefrom. The sleeve 420 may be welded to the top surface of the cap plate 410 along an exterior seam between a bottom of the sleeve and the cap plate top surface.
The sleeve 320, 420 may have a height that is substantially similar to a thickness of the decking and the concrete floor, i.e., the height of each sleeve 320, 420 may provide an indication for a height of concrete to be poured for a deck. In one embodiment of the present invention, the decking is provided by corrugated steel. A top end of the sleeve 320, 420 may act as a benchmark for pouring concrete for the concrete floor. In one embodiment of the present invention, a lubricant such as vegetable oil is applied to an interior of the sleeve 320, 420. An opening in the top end of the sleeve 320, 420 may be covered to prevent concrete from entering therein. In one embodiment of the present invention, a foam is sprayed in the interior of the sleeve 320, 420 to prevent concrete from entering therein. After the deck is installed and the opening of the sleeve 320, 420 is covered, the concrete is poured and leveled. After the concrete cures and is sealed, the opening of the sleeve 320, 420 is cleared. In one embodiment of the present invention, an extractor tool is used to remove the foam from the opening of the sleeve 320, 420. The sleeve 320, 420 may be removably filled with foam as described herein.
In multistory building projects involving more than two (2) stories, the system 100 may include at least one upper-floor column 500 with a cross-sectional shape that is substantially similar to a cross-sectional shape of the sleeve 320, 420 for each floor above the second floor. An exterior dimension of the at least one upper-floor column 500 is slightly smaller than an interior dimension of a lower-story sleeve. In one embodiment present invention, the exterior dimension of the at least one upper-floor column 500 is substantially similar to an exterior dimension of at least one lower-floor column. In another embodiment of the present invention, the exterior dimension of the at least one upper-floor column 500 is slightly less than the exterior dimension of the at least one lower-floor column. The at least one upper-floor column 500 may be configured to matingly engage with the lower-story sleeve, so that a bottom end of the at least one upper-floor column extends into the lower-story sleeve. The at least one upper-floor column 500 may be adjusted within the lower-story sleeve so as to be trued and plumbed and so as to achieve a desired height according to engineering plans to support the load from a higher floor of the multistory building. The at least one upper-floor column 500 may be affixed to the lower-story sleeve by welding or by other suitable means according to engineering plans.
The at least one upper-floor column 500 may have a cap plate 510 affixed to a top end thereof. The cap plate 510 may have a width consistent with a width of the at least one upper-floor column 500. The cap plate 510 may have a length that is longer than a length of the at least one upper-floor column 500. In one embodiment of the present invention, the length of the cap plate 510 is six inches (6″) longer than the length of the at least one upper-floor column 500. The cap plate 510, according to one embodiment of the present invention, may be positioned on the top end of the at least one upper-floor column 500 so that approximately three inches (3″) of the cap plate extends horizontally beyond a first side of the length of the at least one upper-floor column and so that approximately three inches (3″) of the cap plate extends horizontally beyond an opposite second side of the length of the at least one upper-floor column. The at least one upper-floor column 500 may have at least one sheer tab 530 affixed to the width of the at least one upper-floor column oriented vertically. The at least one sheer tab 530 may be configured to be affixed to an end of a beam. The at least one sheer tab 530 may be positioned so that when the beam is affixed thereto, the beam and the cap plate 510 may support a decking for a concrete floor. The at least one upper-floor column 500 may have a sleeve 520 affixed to a top surface of the cap plate 510 extending vertically therefrom. The sleeve 520 may be welded to the top surface of the cap plate 510 along an exterior seam between a bottom of the sleeve and the cap plate top surface.
The sleeve 520 may have a height that is substantially similar to a thickness of the decking and the concrete floor. In one embodiment of the present invention, the decking is provided by corrugated steel. A top end of the sleeve 520 may act as a benchmark for pouring concrete for the concrete floor. In one embodiment present invention, a lubricant such as vegetable oil is applied to an interior of the sleeve 520. An opening in the top end of the sleeve 520 may be covered to prevent concrete from entering therein. In one embodiment of the present invention, a foam is sprayed in the interior of the sleeve 520 to prevent concrete from entering therein. After the deck is installed and the opening of the sleeve 520 is covered, the concrete is poured and leveled. After the concrete cures and is sealed, the opening of the sleeve 520 is cleared. In one embodiment of the present invention, an extractor tool is used to remove the foam from the opening of the sleeve 520.
In one embodiment of the present invention, at least one base plate is positioned on a concrete slab of a multistory building site at a location suitable for carrying a load from at least one upper floor of the multistory building and is attached thereto. At least one first-floor column matingly engages with the sleeve of the at least one base plate so that the sleeve extends into the bottom end of the at least one first-floor column. The at least one first-floor column is trued and plumbed on the sleeve of the at least one base plate and is positioned at a desired height according to engineering plans to support the load from the at least one upper floor of the multistory building. The at least one first-floor column is welded to the base plate according to engineering plans.
Beams are attached to sheer tabs on either side of the at least one first-floor column. A steel deck is installed supported by the beams and the cap plate. The interior of the sleeve of the at least one first-floor column is lubricated with vegetable oil and then filled with foam Concrete for the second floor is poured using the top of the sleeve of the at least one first-floor column as a benchmark. Once the concrete cures and is sealed, the foam is removed from the sleeve of the at least one first-floor column. The bottom end of the at least one second-floor column is inserted into the sleeve of the at least one first-floor column. The at least one second-floor column is trued and plumbed within the sleeve of the at least one first-floor column and is positioned at a desired height according to engineering plans to support the load from the at least one upper floor of the multistory building The at least one second-floor column is welded to the sleeve of the at least one first-floor column. For each floor above the second floor, the process is repeated with at least one upper-floor column at each level of the multistory building.
