Description

Technical Field

[0001] The present invention relates to a building system and a construction method thereof.

[0002] Embodiments of the present invention relate to, but are not necessarily limited to, building systems and methods, and in particular to engagement members for use in the construction of floors for building structures, such as composite steel-concrete floor structures having permanent formwork that supports concrete.

Background Art

[0003] The following description of the background art is for the sole purpose of facilitating an understanding of the present invention. The description is not an admission or acknowledgement that any of the materials referred to were, or were part of, common general knowledge at the priority date of the present application.

[0004] Constructing multi-story building structures is a relatively complex and time-consuming task, thus increasing the cost of constructing these particular building structures. This is particularly true due to the fact that a plurality of relatively heavy building materials need to be assembled using heavy machinery such as a concrete mixer truck having a crane and a concrete placing boom. Also, for example, the assembly of floor and wall structures requires a relatively large number of construction workers.

[0005] In particular, in conventional building structures (such as those typically used as parking facilities and thus capable of withstanding relatively large loads), the floor structure may be defined by floor panels spanning between a plurality of hollow core planks (defining support beams), the planks together forming a support structure onto which a concrete mixture is poured to define the floor structure.

[Figure 32] Figure 31 shows a lifting device for transporting modular connecting structural elements and engaging member configurations. [Figure 33] This figure shows an engaging member having the function of receiving a connecting member according to an embodiment of the present invention. [Figure 34] This figure shows a holding device for detachably holding connecting members according to an embodiment of the present invention to their respective engaging members (e.g., support brackets). [Modes for carrying out the invention]

[0057] The present invention relates to a connection system and method for connecting structural elements (such as panels or sheets or metal decks, e.g., pre-formed metal decks that provide permanent formwork for supporting concrete slabs) to supporting structural elements (such as beams, e.g., continuous void beams or prestressed hollow core precast beams) using engaging members, wherein the engaging members are configured to be in a state of dynamic equilibrium when engaged with these elements, for example, by engagement without fasteners.

[0058] Dynamic equilibrium refers to a state in which, due to the fact that the sum of the forces applied to an object (for example, while at rest) is zero, neither translational nor angular acceleration occurs. Therefore, while an engaging member is attached to, for example, a support structure element, the engaging member remains engaged with these elements.

[0059] Fastener-free engagement refers to the engagement between two elements (such as a support element and a structural element) that places the elements into a state of dynamic equilibrium without the need for fasteners.

[0060] The connection system according to this embodiment of the present invention is particularly advantageous to include one or more engaging members, which are configured to be in a state of dynamic equilibrium without the need for fasteners when they are first engaged with, for example, a support structure and / or structural element. This is particularly advantageous because, since they are in a state of dynamic equilibrium (without the need for fasteners), the engaging members remain stationary, facilitating the assembly of building structures such as floor structures; in particular, defining floor structures using relatively lightweight materials but capable of withstanding relatively large loads. This facilitates assembly because the step of applying fasteners to define the connection between both elements can be omitted until the support structure is defined.

[0061] Floor structures made from relatively lightweight materials and easy to assemble are widely used for constructing building structures such as parking facilities, as shown in Figure 1.

[0062] As shown in Figure 1 as an example, the building structure 10 comprises a main area 12 and an access area 14. The access area 14 includes stairs and ramps, enabling vehicles and pedestrians to access the main area 12 of the building structure 10.

[0063] The main area 12 comprises a floor structure 16 that defines parking spaces 18 for parking vehicles, and passages 20 and walkways 22 that allow vehicles and pedestrians to access the parking spaces to park and retrieve vehicles.

[0064] Figure 2 shows a schematic plan view of a floor structure 16 that includes multiple parking spaces separated by a passageway 20. The floor structure 16 is defined by a support structure 24 into which a concrete mixture is poured and hardened.

[0065] The support structure 24 shown in Figure 5 includes two adjacent sections 26 and 28. Each section 26 and 28 includes a number of beams 30 (support structure elements) spaced apart from each other, defining a spacing 32 (e.g., 32a) between adjacent beams (e.g., 30a and 30b) for accommodating a panel structure 34 (see Figure 5).

[0066] The panel structure 34 extends between the side surfaces 38 of the beam 30. The ends 38a and 38b (see Figure 5) of the panel structure 34 are attached via the connection system and method according to this embodiment of the present invention, as will be described later with reference to the construction method of the floor structure 16.

[0067] A specific arrangement of the panel structure 34 shown in Figure 5 includes multiple panels 42 (structural elements) arranged side by side; in particular, there are four panels 42a to 42d. Other configurations of the panel structure 34 may include a single panel 42 or any number of panels 42.

[0068] In a particular configuration of the floor structure 16 described herein, each panel 42 comprises a sheet structure 44 (structural element), for example, an elongated sheet configured for reinforcement of the sheet structure 44. Figure 7 shows such a sheet structure 44. A particular example of the sheet structure 44 used is a pre-formed metal deck that serves as a permanent formwork.

[0069] Referring here to Figure 6, as previously described, the support structure 24 of the floor structure 16 is defined by supporting the end of the panel structure 34 on the side surface 38 of the beam 30 via a connecting system incorporating engaging members 46, the engaging members 46, when engaged, enter a state of dynamic equilibrium, facilitating the definition of the support structure 24. Once the support structure 24 is defined as shown in Figure 19, a concrete layer 40 (see Figure 6) is poured over the panel structure 34 and beam 30 to complete the floor structure 16. One or more restraining straps 35 can support the edge form 37 against the outer longitudinal side surface of the panel structure. The edge form can restrain the poured concrete at the outer edge of the panel structure.

[0070] As shown in Figures 5 and 6, each end 38 of each panel 42 incorporates an engaging member 46, allowing the end 38 of each panel 42 to engage with the side surface 38 of the beam 30. The panel structure 34 (defined by one or more adjacent panels 42) is positioned between the beams 30, such as beams 30a and 30b, allowing engagement to occur between the end 38 of the panel 42 and the side surface 38 of the beam 30.

[0071] According to this embodiment of the present invention, engagement with the end portion 38 is performed relatively quickly and easily, while ensuring that the engaging member 46 is properly fixed to the panel 42 and that the panel is in a state of dynamic equilibrium while engaged with the panel 42. The engaging member 46 is adapted to engage with the end portion 38 of the panel 42 in such a manner. In this way, the panel 42 can be quickly prepared for the assembly of the panel structure 34 that spans between the beams 30a.

[0072] Furthermore, the engaging member 46 is also adapted to engage with the side surface 38 of the beam 30 in a rapid manner and in a single step, and rests on the side surface 38 in a state of dynamic equilibrium when attached to the side surface 38 while engaged with the panel 42.

[0073] Figures 8-11 show the first configuration of the engaging member 46 according to this embodiment of the present invention.

[0074] As shown in Figure 8, the engaging member 46 comprises a body defined by a receiving end 48 (second end) and a supporting end 50 (first end). The receiving end 48 is fitted to engage with the end 38 of the panel 42, and the supporting end 50 is fitted to engage with the side surface 36 of the beam 30.

[0075] In the specific configuration shown in the drawings, for example in Figures 8 to 11, the body of the engaging member 46 defines spaced engaging bars 52a and 52b (defining the lower assemblies) and spacing bars 54a and 54b.

[0076] Each engaging bar 52 has a support end 50 (first end) and a receiving end 48 (second end) of the engaging member 46, and the spacing bars 54a and 54b are attached to the inside 60 of the engaging bar 52 at the ends 56 and 58 of the engaging bar 52, respectively.

[0077] As described above, the receiving end 48 of the engaging member 46 is fitted to engage with the end 38 of the panel 42. For this purpose, the receiving end 48 of each engaging bar 52 is provided with an engaging unit 62 attached to each engaging bar 52. Each engaging unit 52 is fitted to receive the end 38 (first end) of the panel 42.

[0078] Figures 9 and 10 show the rear and side views, respectively, of the engagement unit 62.

[0079] The engaging unit 62 is attached to the engaging bar 52 and includes a finger element 64 that is partially fixed to the engaging bar 52, forming a gap between the finger element 64 and the engaging bar 52. The gap defines a slot 66 for at least partially receiving and fixing a portion of the end 38 of the panel 42 that engages with the engaging member 46.

[0080] In the configuration shown in Figures 8-11, the distal end 68 of the finger element 64 is fixed to the engagement bar 52, while the remaining portion (referred to as the proximal end 70) is spaced apart from the engagement bar 52 to define the slot 66. The distal end 68 may be fixed by welding or by any other suitable fixing system 72.

[0081] Furthermore, the engaging unit 62 can be fixed to the panel 42 via a fastening system 74 that is screwed into the engaging bar 52 based on a screw that crosses the end 38 of the panel 42, for example, in the configuration shown in Figure 10. Alternatively, any other suitable fastening system may be used.

[0082] Referring to Figure 12, as mentioned above, when in use, the panel structure 34 is spanned between the beams 30 and defines the support structure 34. The panel structure 34 may consist of only one panel 42, or it may consist of multiple panels 42 arranged side by side, as shown in Figure 5.

[0083] According to this embodiment of the present invention, a method for assembling a support structure 24 is provided.

[0084] The assembly method includes the step of attaching one or more panels 42 onto adjacent beams 30 (e.g., beams 30a and 20b in Figure 4) using engaging members 46 (when the beams 30 are spaced apart as shown in Figures 3 and 4), the panels 42 are positioned next to each other and spanned between adjacent beams 30. The panels 42 (attaching the engaging members 46 in a dynamic equilibrium state) are attached one by one onto the beams 30, so that the sides of adjacent panels 42 are properly engaged with each other (see Figure 14), and the engaging elements 46 also ensure that they properly engage with the sides 16 of the beams 30, as shown in Figures 6 and 12. In this regard, the engaging members 46 are attached to the sides 38 of the beams 30, and the engaging members 46 are in a dynamic equilibrium state while engaged with the sides 38 of the beams.

[0085] The connection between the panel 42 and the engaging member 46 is considered an in-plane moment connection, and the in-plane moment is resisted by the stiffness of the engaging unit 62 (upper bar assembly), the self-perforating screw, and each element in the connection.

[0086] In this regard, theoretical analysis of the behavior of the engaging member 46 indicates that when the panel 42 (particularly the sheet metal deck 210) is fitted into the engaging member 46 and placed on the side surface 38 of the beam 30, the self-weight of the panel 42 (0.133, 0.159, and 0.197 kN / m for 1.0, 1.2, and 1.5 BMT, respectively) is such that the engaging member 46 behaves as follows: 2 This predicts that the engaging member 46 will rotate around the edge of the bearing pad. However, this rotation is constrained by the panel 42 through the engagement of the engaging member 46. As a result, the engaging member 46 (panel 42) is in a state of dynamic equilibrium.

[0087] The support structure 24 is defined by a panel structure 34 that spans between the beams 30, allowing construction workers to verify that the support structure 24 is properly assembled; and workers can then secure the engaging members 46 to the sides 38 of the beams 30 (via screwing).

[0088] The maximum potential load from panel 42 during the screwing process is transmitted to beam 30 via the engaging member 46, as shown in Figure 20. The rotation caused by the clockwise moment resulting from the loads from panel 42 and beam 30 is resisted by the counterclockwise moment generated by the engaging unit 62. Because the engaging member 46 is in a state of dynamic equilibrium, the support structure 46 remains stationary under the load during the screwing process.

[0089] Next, the concrete layer 40 is applied (see Figure 6), defining the floor structure 16 as shown in Figure 6.

[0090] The method according to this embodiment of the present invention is particularly advantageous because it greatly facilitates the assembly of the floor structure 16. This is especially true because the assembly of the floor structure 16 is carried out using a specific construction process, and as the construction process progresses by carrying out the construction steps sequentially, the strength of the floor structure 16 under construction increases in stages.

[0091] For example, in this configuration of the construction method for floor structure 16, the construction process includes the following steps: a. A step of attaching panels 42 (including engaging members 46) one by one onto a beam 30, wherein the engaging member 46 engages with the side surface 38 of the beam 30, and the side surfaces of adjacent panels 42 engage with each other; b. The process of fixing the engaging member 46 to the beam 30 via the fastening system 74; c. The process of pouring the concrete mixture onto the support structure 34 and allowing it to harden.

[0092] As the construction process of the floor structure 16 progresses, it becomes clear that the strength of the supporting structure 34 increases, particularly from the following: a. The engaging member 46 is attached to the end of the panel 42, and the engaging member 46 is in a state of dynamic equilibrium; b. Panel 42 is supported on the beam via engaging member 46 in a state of dynamic equilibrium; c. The engaging member 46 can be fixed to the beam 30 via the fastening system 74 while in a state of dynamic equilibrium; and d. Finally, a concrete layer is formed on the support structure 24, which is in a state of dynamic equilibrium, to define the floor structure 16.

[0093] This is made possible by configuring the engaging member 46 to be in a state of dynamic equilibrium while it is engaged with the end of the panel 42 via a fastener-free engagement (no fastening system) and rests on the side surface 38 of the beam 30.

[0094] This gradual reinforcement process facilitates the construction process and reduces the number of construction workers required to safely construct the building structure. In fact, for example, defining panel structures 34 that span between beams (supported on engaging members 46 in a state of dynamic equilibrium) would save time without compromising the safety of construction workers and equipment.

[0095] Once the panel structure 34 is spanned between the beams 30, which are supported only on the beams 30 via engaging members 46, a small number of construction workers (one or more) can quickly fasten the panels 42 via the fastening system 74, and then pour concrete mixture onto the support structure 24 to define the floor structure 16.

[0096] Next, referring to Figures 14 to 18, which show a second arrangement of the engaging member 46. The second arrangement of the engaging member 46 comprises a single engaging unit 62 (upper assembly) adapted to receive the end 38 of the panel 42. This is in contrast to the first arrangement of the engaging member 46 in which multiple engaging units 62 are used.

[0097] In particular, as shown in Figures 14 to 18, each engagement unit 62 is equipped with a plurality of support bars 52, the finger members 64 are attached to the support bars 52, and the support bars 52 are spaced apart from each other to define a gap 76 (see Figure 16).

[0098] The finger members 64 are partially attached to a plurality of support members 52 via a fixing system 72 (see Figure 20) and define slots 66 adapted to receive a portion of the end 58 of the panel 42, as described above with reference to Figure 5.

[0099] In the specific configurations shown in Figures 15 and 16, the fastening system 72 is defined by a screw assembly. In the specific configurations shown in Figures 17 and 18, the fastening system 72 is defined by a full penetration butt weld.

[0100] The proximal end 68 of the finger member 64 extends (1) from the mounting point between the finger member 64 and the support bar 52 to (2) the end 78 of the support bar 52 that defines the entrance to a slot 66 for receiving the end 38 of the panel 42 at that position. In this way, the slot 66 has a greater depth than the slot 66 of the first configuration of the engagement unit 62 shown in Figure 10.

[0101] Furthermore, the end 70 of the finger member 64 extends above the support end 50 of the support bar 52, defining an additional slot for receiving the shim 80.

[0102] When in use, typically, as shown in Figure 14, there is a pair of engaging members 46 according to the second configuration of this embodiment of the present invention, attached to the end 38 of the panel 42. The method of assembling the support structure 24 is substantially the same as when using the engaging members 46 according to the first configuration shown in Figures 8 to 11.

[0103] Figures 20 and 21 show examples of engaging members 46 (also referred to as support bracket type 1 and type 2, respectively) according to this embodiment of the present invention. It should be understood that the scope of protection required is not limited to these two examples. Figure 22 shows an engaging member 46 in use, mounted on a panel 42.

[0104] Figure 23 shows a free-form view of support bracket type 1 (engaging member 46 shown in Figure 20) in the clamp-released state during installation.

[0105] Figure 24 shows a free-form view of support bracket type 1 (engaging member 46 shown in Figure 20) in the clamped state during installation.

[0106] Modifications and variations that would be obvious to those skilled in the art are considered to be within the scope of the present invention.

[0107] In this regard, the specific configuration of the support structure 24 (excluding the panel structure 34) shown in Figure 3 is defined by a plurality of single beams 30 arranged at a distance from one another.

[0108] However, in an alternative configuration, a particular support structure 24 may be defined by a group of beams 30 arranged spaced apart from one another, each group comprising multiple beams 30 mounted side by side, as shown in Figure 6.

[0109] An interface 47, such as an elastic pad, can be provided between each engaging member 46 (e.g., a support bracket) and a support structural element 30 (such as a concrete beam or other fixed structure).

[0110] The embodiment of the engaging member 46 may preferably include a reinforcing member 71, such as a sleeve, at at least one end of the engaging member. The reinforcing member may be provided at the end of the engaging member / bracket 46 that is supported on a supporting structural element 30 (such as a concrete beam or other structural member of a building).

[0111] The bracket 46 may include a receiving portion 73 for engaging with the connecting member 81. The connecting member 81 may include or be an elongated member such as a metal rod, bar, or reinforcing bar.

[0112] The retaining member 83 can engage with each end of the connecting member 81. The retaining member 83 may also be locked to an adjacent bracket 46 by a locking means 85 such as a pin, screw, or other fastener to prevent the connecting member 81 from disengaging prematurely from the floor member.

[0113] Multiple floor members can be connected to each other to form a panel structure such as multiple interconnected metal deck elements. Multiple brackets can engage with opposing ends of the panel structure, for example, as shown in Figure 31. The connecting member 81 can engage with the bracket 46 at each end of the panel structure.

[0114] The lifting device 90 engages with the connecting member 81 to lift the panel structure to a supported position on the structural floor support before the bracket is secured with fasteners and concrete is subsequently poured onto the panel structure. The lifting device may include suspension members, such as cables, chains, or other elongated suspension members, which can be detachably attached to the connecting member 81 at the mounting position 91. Spreader bars can be used to connect the elongated members to lifting means such as crane hooks.
