Description

TECHNICAL FIELD

The present disclosure relates generally to reinforce structures, and more specifically, to bracing systems for strengthening beams.

DESCRIPTION OF RELATED ART

The approaches described in this section could be pursued but are not necessarily approaches that have been previously conceived or pursued. Therefore, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section.
Traditionally, beams are used in foundation constructions for buildings, and especially used in low storey houses. The beams are typically wooden, and used to support such building elements as walls, floor structures, roof structures, and so forth.
Reinstatement or strengthening of beams in existing buildings is an important problem. In many instances, beams may require strengthening during a reconstruction process, e.g. when an additional floor is to be added to the building, or when the foundation was damaged by a flood. In addition, the wooden beams are most vulnerable to rot, decay or similar degradation, and thus may require strengthening. If a utility beam should fail during reconstruction process or when the beam is weaken, there may be a serious damage to the building. Further, the sudden failure of a beam in the building is a danger to life and health of the building habitants.
In view of the above reasons wooden beams may require reinforcement during reparation or reconstruction processes. However, today's technology is directed either to adding new beams or substitution of the existing ones, or, alternatively, to reinforcing the beams in existing buildings with bulky support members. Such members are usually made of metal and typically represent heavy profile elements like flat panels or L-, T- or H-section railings. The problem with such support members is that it's very difficult to install them. They are bulky and heavy, and property holders or workers may experience problems with their installation, especially when they work alone. Moreover, the discussed support members have to be of a fixed length to fit specific conditions of the existing buildings, which also add problems with their manufacturing.
Accordingly there exists a need for a reinforcing system which can be easily mounted to any beam in the existing building to strength it.

SUMMARY

The following presents a simplified summary of one or more embodiments in order to provide a basic understanding to the reader of such embodiments. This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
In accordance with one or more embodiments and the corresponding disclosure thereof, various aspects are described herein in connection with a bracing system and a method of its installation.
The bracing system is a set of support panels and a set of crossover panels. The both panels may have an oblong square-like shape. The support panels comprise connection members at their both ends such that these panels may be connected to each other, and form a line. The connection members may be made out as a few ribs at the panel, where the ribs are oriented in the direction of the support panel axis. The ribs may be formed in a square-like hollow existing at both ends of the support panel. Accordingly, each two support panels may be connected/interlocked to each other by joining the ribs of one support panel with corresponding empties between ribs of the other support panel. Hence, the support panels may be connected to each other to form a line.
The support panels are designed to be fixed to a wooden beam. The beam should be provided with two parallel lines of interconnected support panels. Such lines may be fixed on the same flat side of the beam in proximity to its opposite edges. In one example, the lines of the support panels may be fixed at the distance 0.5-5 inches from the edge.
The supporting panels may be fixed to the beam with the help of bolts, screws, studs, anchors (e.g., mechanical anchors, bonded anchors, etc.), wire nails, and so forth. The supporting panels may also comprise through holes necessary for driving the bolts/screws through them.
The crossover panels are designed to link the support panels related to the opposite lines. In other words, each one of the crossover panels is designed to be connected to both support panels of both parallel lines.
According to various embodiments, the crossover panels may be crossed to provide better rigidity of the system. In the place where two crossover panels are crossed, they may be connected to each other with the help of a bolt, a screw, and the like.
Further, the crossover panels may be received in corresponding recesses arranged in the support panels, and be connected to the support panels (and the beam) with the help of bolts, screws, studs, nails, and so forth.
All panels can be made of metal, plastic, synthetic, semi-synthetic, or other materials, or any combination thereof.
Thus, the bracing system allows adding tremendous strength to wood beams in existing buildings. The bracing system can be installed by a single person without using machines to lift heavy steel panels or support members. It also does not require welding, and thus it is very easy to install. Further, the bracing system can be made of any length, and that's make it more profitable and applicable to reinforce any building.

As used herein, the term “beam” refers to a structural element that is capable of withstanding load primarily by resisting bending which can be induced as a result of the external loads, forces, own weight, span and external reactions to these loads. The beams are typically used in a building to support building elements such as walls, floor structures, roof structures, and so forth. In terms of this document, the beam may also refer to a timber or a pole.
Referring now to the drawings, FIGS. 1A-1F illustrate a support panel 100, its corresponding cross sections and its an axial section, in accordance with an exemplary embodiment.
In general, the support panel 100 has an oblong square-like shape. The support panel 100 comprises two connection means 102, 104 at both ends. The connection members comprise a number of ribs and corresponding empties between them (or, alternatively, a rack rod of any suitable design). These ribs may be formed in a hollow of the support panel 100.
As shown in FIG. 1B, the first connection means 102 comprises two square-like ribs 106 oriented along the axis of the support panel. There three empties are arranged between the ribs 106. Accordingly, as shown in FIG. 1E, the second connection means 104 comprises three square-like ribs 106, and two empties 108.
In the shown example, ribs are designed on different and opposite sides of the support panel 100 such that two support panels 100 may be connected to each other by joining ribs 106 of the first connection means with the empties 108 of the second connection means, and vice versa.
The support panel 100 comprises several through holes 110A, 110B which are designed to connect the support panel 100 to the beam. The connection can be performed with the help of bolts, screws, studs, anchors, wire nails, and so forth. The through holes 110A, 110B may be of different diameter. Some holes 110 may also be designed to connect the support panel 100 with the beam and/or one or more crossover panels, which will be discussed further with reference to FIG. 2.
The support panel 100 further comprises recesses 112 to receive endings of the crossover panels. The recess 112 may optionally replicate the shape of the crossover panels.
FIGS. 2A-2E illustrate a top view of a crossover panel 200 and also its corresponding cross sections, in accordance with an exemplary embodiment.
In general, the crossover panel 200 has an oblong square-like shape. The endings of the crossover panels may be oblique.
As shown in the figures, the crossover panel 200 may comprise two recesses 202 at both ends. These recesses 202 are designed to be joined with recesses 112 arranged in the support panels 100.
The crossover panel 200 may also comprise a recess 204 arranged in the middle of the panel. The recess 204 is designed in such a way that two crossover panels 200 may be crosswise connected to each other by joining (and possibly interlocking) their corresponding recesses 204.
The crossover panel 200 may also comprise through holes 206 to connect two crossover panels 200 to each other (a centrally located hole) and/or to connect the crossover panel 200 to the support panel 100 and/or the beam. The connection can be performed with the help of bolts, screws, studs, anchors, wire nails, and so forth.
FIGS. 3A-3D illustrate a process of installing the bracing system to the beam, according to an example embodiment.
FIG. 3A shows the beam 300 which requires to be reinforced. A fixing person (i.e. a user) may first mark two chalk lines 302 one inch inside to the edge of the beam 300. Then, two support panels 100 are placed to the beam 300 aligned to the chalk lines 302 and hammered to the beam using two nail wires via the through holes 110A. The user then drills the beam through four holes 110B in each support panel 100.
At the next step, as shown in FIG. 3B, the user places the next two support panels 100 to the already fixed support panels 100. The connection is made through the connection means 102 of both panels such that ribs 106 of one panel are inserted into the empties 108 of the other panel.
The user fixes the new support panels 100 to the beam 300 and also drills the beam 300 via the holes as described above. The user then places two bolts to the holes 304, and connects the support panels 100 to the beam 300.
At the next step, as shown in FIG. 3C, the user places the first crossover panel 200 such that it is connected with two support panels 100 which are located at opposite sides. The user then places two bolts to the previously drilled holes 306 and tights them.
Further, the user places the second crossover panel 200, as shown in FIG. 3D, such that the first and the second crossover panels 200 are crossed. The user places bolts to the holes 308 that are previously drilled, and tighten them.
The user may optionally connect the first and the second crossover panels 200 in the place of their crossing. The connection can be made with the help of a bolt or the like means.
The same procedure is followed and the user fixes the required number of support panels 100 and the crossover panels 200 symmetrically at both sides from the beam centre. The endings may be accomplished with any suitable supporting element. In one example, there may be provided a half length support panels 100 (not shown). Alternatively, any railing, or a profile element can be used.
FIG. 4 shows a perspective view of the assembled bracing system 400 fixed to the beam 300, according to an example embodiment. Although it is shown that the bracing system 400 is attached to one side of the beam 300, it should be apparent that bracing system 400 can be attached to two sides, or even all of them.
As shown, the beam 300 has substantially a square-like form. However, the beam 300 may be of any other form, for example, it may have a circular cross section. In this case, the crossover panels 200 may be designed curved (e.g. a semi-circular, and the like). Those skilled in the art would appreciate that any suitable form of the crossover panels 200 may be used.
Thus, a novel bracing system and method of reinforcing a beam are provided. It was shown that the bracing system adds tremendous strength to the wood beams, and prevents from fail when a load to the beam is increased, or when the beam is weakened. In particular, it was demonstrated that a braced beam's load carrying capacity may be increased by over 450% by installing the bracing system as described in this document.
Although embodiments have been described with reference to specific example embodiments, it will be evident that various modifications and changes can be made to these example embodiments without departing from the broader spirit and scope of the present application. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
