Description

Technical Field

[0001] The present invention relates to an engineered wood structure system for constructing structures mainly or entirely composed of components formed of engineered wood, which components are preferably connected to each other by using durable moisture-resistant structural adhesives such as polyurethane or other resins. Background Art

[0002] Structural systems formed of engineered wood are known in the prior art.

[0003] For example, document WO2016191510A1 describes an engineered wood structure system including wall panels and beam or slab-like horizontal structural elements. Each beam includes an upper horizontal plate, a lower horizontal plate, and a second spacer located between the upper horizontal plate and the lower horizontal plate and attached to the upper horizontal plate and the lower horizontal plate. The slab is composed of structural floor levels, each slab being supported on the beam and including an upper horizontal plate and a lower horizontal plate separated and connected by the second spacer, the second spacer being defined by a first rib and a second rib perpendicular to the first rib. The wall panel has a structure similar to that of the slab, but includes a first support at its upper end, and a second support defined by the second spacer of the beam is engaged and supported, defining a structural joint for transferring vertical loads from the beam to the wall panel.

[0004] This solution allows for the prefabrication and subsequent assembly of different structural elements of the structural system.

[0005] Through the structural joints proposed in this solution, the connection between different structural elements allows for the transfer of vertical loads, such as from the beam to the wall panel, but prevents the structural continuity of the wall panel through the structural joint and the transfer of bending loads therethrough.

[0006] Furthermore, different horizontal structural elements converging at the same structural joint are not connected to each other, and cannot transfer loads between them or compensate for the loads between the converging horizontal structural elements.

[0007] In addition, the proposed connection between the horizontal structural element and the wall panel is not a rigid connection. Therefore, other loads different from vertical loads (such as shear loads, bending loads, or torsional loads) cannot be properly transmitted across different structural elements. According to this solution, vertical loads are transmitted through the wall panel, but the beams are stacked on top of the wall panel, and their vertical continuity is interrupted. When three or more structural plate layers are overlapped and supported on the wall panel, it prevents the vertical transmission of loads through the wall panel. If the vertical loads cannot be continuously transmitted through the structural element (in this case, the wall panel) designed to transmit vertical loads, the vertical loads supported by the structural element are reduced, and the size, load resistance, and price of the structural system will be negatively affected.

[0008] Document US3866371A also describes an engineered wood structure system that includes vertical structural elements defined by continuous columns and horizontal structural elements in the form of beams connected to the sides of the vertical structural elements for transmitting loads between converging beams, thereby allowing compensation of the loads. The vertical structural elements pass through the hollow of the beams.

[0009] Each beam is composed of a left plate and a right plate facing each other, and a space through which the vertical structural element passes is defined between the left plate and the right plate.

[0010] The load resistance of the vertical structural element defined in this solution is reduced in the face of bending forces.

[0011] In addition, in the case where beams in the first direction and the second direction (for example, the first and second orthogonal directions) converge on the same vertical structural element, the vertical connectors of the beams in the first direction interfere with and partially interrupt the vertical connectors of the beams in the second direction, and only half of the total vertical height of each vertical connector is continuously spanned across the structural nodes connected to the opposing beams, which has a negative impact on the load resistance of the vertical connectors and reduces the load transmission between the connected beams. This solution only allows the connection between aligned beams but does not allow the proper transmission of loads between non-aligned beams that converge on the same vertical structural element.

[0012] Document US20100275551 describes a connection between two aligned portions of a beam, which is achieved by finger joints on the facing ends and by a lower connector adhered to the lower surface of the beam. In this case, the lower connector is a triangular plate mounted in a complementary groove. In this case, the beam is a solid square beam, which is structurally inefficient and thus expensive compared to other types of beams. This solution also only involves obtaining a long longitudinal beam formed by multiple local beams adhered together, but does not involve the connection of the beam to a vertical structural element, the load transfer between converging beams supported on a vertical structural element, or the load transfer from the converging beams to a vertical structural element.

[0013] Document EP0550803A1 describes a connection system between similar aligned beams as described in document US20100275551. In this case, the beam is also a solid square beam, and the connector is integrated in the recessed staggered stepped portion of the beam. However, in this document, when applying this solution to the connection between converging beams and a vertical structural element, only a vertical connector formed by a vertical plate adhered to the lateral vertical surfaces of the beam and the vertical structural element is proposed, through which bending loads are transferred, and only connections between aligned beams are allowed, not connections with beams converging from other different directions. As described above, engineered wood is more efficient in transferring compression of tensile loads than in transferring bending loads. Therefore, the vertical connector proposed in this document is not the most efficient way to utilize engineered wood and has a negative impact on the efficiency of the structural system. This document does not propose the continuity of vertical load transfer in the vertical structural element when multiple overlapping layers of structural plates are supported on it.

[0014] Document EP0079761A1 describes a structural system including a beam that includes an upper horizontal plate and a lower horizontal plate connected by a second spacer, the ends of which are connected to a vertical structural element including a first support for the second spacer, but this document does not describe the connection between different beams converging on the same vertical structural element.

[0015] Document FR2613403A1 describes an engineered wood structural system that includes a vertical structural element formed by four L-shaped vertical struts. Vertical flat slats can be inserted between the vertical struts and bolted together to provide a hinged joint. This solution does not allow several horizontal structural segments converging at the same structural node to be connected to each other to transfer tensile and compressive forces.

[0016] Documents FR2133487A1, WO2015011300A1, and WO2015121886A1 also describe other engineered wood structural systems.

[0017] The present invention solves the above and other problems. Summary of the Invention

[0018] The present invention relates to an engineered wood structure system formed by engineered wood members.

[0019] It can be understood that engineered wood is a derived wood product formed by a composite material that combines or secures wood chips, particles, fibers, veneers, or boards of wood, wood chips, wood flour, or other plant products (such as bamboo) with an adhesive. This type of wood is also known as mass timber, composite wood, artificial wood, or wood-based panel.

[0020] The most common engineered woods are plywood, which is formed by multiple layers of veneers with alternating directions and bonded with a durable moisture-resistant adhesive under high temperature and pressure; laminated veneer lumber (LVL), which is similar to plywood except that all veneers are stacked in the same direction; oriented strand board (OSB), formed by wood strands compressed and bonded together in multiple directions; laminated strand lumber (LSL), which is similar to OSB except that the wood strands are stacked in the same direction; and medium-density fiberboard, formed by wood fibers or sawdust pressed and glued together. Other types of engineered wood products are commonly referred to as glued laminated timber (Glulam), engineered wood products (EWP), and cross-laminated timber (CLT).

[0021] The object of the present invention is to describe a structural system that uses engineered wood as the main structural component, which not only includes structural elements but also the connections between these structural elements.

[0022] Preferably, for the main engineered wood components of the present invention, or at least for the engineered wood components that support higher loads, the engineered wood has a maximum compressive strength between 20 N / mm 2 and 40 N / mm 2 and / or a maximum shear strength of up to 8 N / mm 2 and the adhesive used preferably has a maximum compressive strength equal to or higher than the compressive strength of the attached engineered wood component and a maximum shear strength equal to or higher than the shear strength of the attached engineered wood component after hardening.

[0023] The structural system includes the following components, which are known in the prior art:

[0024] At least one vertical structural element having a number of structural nodes at different vertical positions corresponding to different plies, each structural node including at least one first support;

[0025] At least one horizontal structural element for each structural node, each horizontal structural element being composed of an upper horizontal plate and a lower horizontal plate, the upper horizontal plate and the lower horizontal plate facing each other, being spaced apart from each other in the vertical direction, and being rigidly connected to each other by a second spacer included between the upper horizontal plate and the lower horizontal plate, at least one horizontal structural element including at least one second support, the second support being supported and vertically overlapping at least one first support of a vertical structural element.

[0026] A plurality of parallel vertical structural elements (i.e., a plurality of parallel struts) can be connected to each other by the horizontal structural elements, thereby defining a structure having a plurality of overlapping structural plate layers.

[0027] Each horizontal structural element includes an upper horizontal plate and a lower horizontal plate, the upper horizontal plate and the lower horizontal plate facing each other and being spaced apart by a distance. The upper horizontal plate and the lower horizontal plate of each horizontal structural element are rigidly attached to each other by at least one second spacer, transmitting shear forces between the upper horizontal plate and the lower horizontal plate, increasing the load resistance of the horizontal structural element, and producing a durable, lightweight, and inexpensive horizontal structural element.

[0028] It should be understood that the word "plate" refers to a thin flat material sheet, which defines two main surfaces and four peripheral surfaces of the plate, the main surfaces having the largest surface area, and the peripheral surfaces connecting the two main surfaces together.

[0029] The length of the plate will be the longest dimension of the main surface, the width of the plate will be the dimension of the main surface perpendicular to the length, and the thickness will be the dimension perpendicular to the length and width.

[0030] It should also be understood that the horizontal or vertical position of a plate or slat refers to the position of its main surface, so a horizontal plate refers to a plate whose main surface is in a mostly horizontal position. When the element is a complex structural element (such as a vertical structural element or a horizontal structural element), its horizontal or vertical direction refers to the direction of its main length.

[0031] Preferably, the first support and the second support are mostly flat and horizontal surfaces facing each other, providing a wide contact area between the first support and the second support to disperse the vertical load transmitted from the horizontal structural element to the vertical structural element. Preferably, when the distance between the vertical structural elements is at least 3 m, the contact area is at least several square centimeters, such as greater than 10 cm 2 or greater than 15 cm 2 . Preferably, both the first support and the second support are made of engineered wood.

[0032] Preferably, the second support is not defined by a through-hole in a horizontal structural element, but by a downwardly exposed surface that does not face other surfaces of the same horizontal structural element, because through-holes reduce the load-bearing resistance of the horizontal structural element in the most stressed areas and make the installation process more difficult.

[0033] For example, the second support can be an area or a reinforced area of the lower horizontal plate, or a part or a reinforced area of the second spacer that is not covered by the lower horizontal plate, and / or a part or a reinforced part of the upper plate that extends in a cantilever form from the rest of the horizontal structural element.

[0034] The second support can be supported directly on the first support or through an intervening element (such as an engineered wood, metal, or plastic intervening element).

[0035] The reinforced area is an area that includes a second spacer that is more durable or more densely filled than the rest of the horizontal structural element, and preferably an area where the second spacer completely fills the space between the lower horizontal plate and the upper plate, preferably filled with engineered wood.

[0036] The horizontal structural element can also include reinforcements in other areas where loads are accumulated or where the loads are greater than in other areas. In these areas, reinforcement can be obtained by using a thicker or stronger material or by including additional material reinforcement layers in the upper connectors or the lower horizontal plate and / or in the ribs that make up the second spacer. This is particularly advantageous in areas where the bending forces are greatest (such as the central area of the horizontal structural element supported between two or four structural nodes or near the said structural nodes).

[0037] The second support is directly supported on the first support to transfer vertical loads. The reinforced area can be, for example, an area of the lower horizontal plate or the second spacer, which has an increased thickness compared to other areas of the same element, or is formed of a more durable material or more durable engineered wood.

[0038] Preferably, the upper horizontal plate, the lower horizontal plate, and optionally the second spacer are formed of engineered wood, and it is also proposed to connect these elements with an adhesive.

[0039] Preferably, the connections between the different elements that make up the proposed structural system are achieved by an adhesive or by a combination of an adhesive with nails or screws. The adhesive distributes the transmitted loads over a wide attachment area, avoiding load concentration that can cause local damage in engineered wood members (usually when connected by only a few screws or nails).

[0040] Preferably, the adhesive used is a durable moisture-resistant structural adhesive, such as polyurethane or other resins (such as epoxy resins).

[0041] Due to the orthotropic nature of wood, engineered wood slats, struts, and boards are generally more load-resistant in a direction parallel to the main surface or main length of the element than in a direction perpendicular to the main surface or main length.

[0042] In the case where the panels of the plywood are adhered in the vertical direction, the difference in load resistance between X and Y is balanced.

[0043] When the load transferred from the horizontal structural element to the first support is lower than a specific threshold, the horizontal structural element can be supported on the first support by a second support defined in the lower horizontal plate, compressing the lower horizontal plate in a direction perpendicular to its main surface. When the load transferred from the horizontal structural element to the first support is higher than the specific threshold, the second support is preferably defined on the second spacer, which may for example include a downwardly projecting protrusion passing through the thickness of the lower horizontal plate, or a part of the second spacer accessible through an area not covered by the lower horizontal plate.

[0044] The vertical struts constituting the vertical structural element are rigidly connected to each other by intervening first spacers, which keep the vertical struts separated from each other and transfer shear forces between them, thereby increasing the overall load resistance of the vertical structural element.

[0045] The vertical struts are preferably formed of engineered wood and may have a square or rectangular cross-section.

[0046] Preferably, the vertical struts and optionally the first spacers and / or the first supports are formed of engineered wood, and it is also proposed to connect these elements with an adhesive.

[0047] The first support may be included between and attached to the vertical surfaces of two facing vertical struts, the first support including an upward-facing surface on which the second support is supported by its downward-facing surface.

[0048] This configuration concentrates the solid part of the vertical structural element at its periphery, where greater load resistance is provided against bending forces, resulting in a rigid vertical structural element with low mass and low cost, and creating a hollow interior of the vertical structural element.

[0049] The region of the horizontal structural element including the second support is inserted into the hollow interior of the vertical structural element, between two facing vertical struts, without interrupting the vertical continuity of the vertical struts.

[0050] The second support is supported on the first support, which is at least partially included in the hollow interior of the vertical structural element between the vertical struts, transferring the vertical load from the horizontal structural element to the vertical structural element.

[0051] Each vertical structural element will receive vertical loads from all the horizontal structural elements attached to it, accumulating vertical loads from multiple structural layers.

[0052] Typically, each vertical structural element is connected to the ground at its lower end, and the ground disperses and transfers all the vertical loads of the vertical structural element to a wider area of the terrain where the structure is located.

[0053] According to one embodiment, the structural system includes a plurality of vertical structural elements parallel to each other, and each vertical structural element includes a first support. A plurality of horizontal structural elements are connected to the vertical structural elements through the first supports, and each connection defines a structural node. Preferably, the sheet elements are supported on the horizontal structural elements, and the horizontal structural elements define several overlapping structural layers on different layers.

[0054] Each of the plurality of horizontal structural elements has a portion included between at least two facing vertical struts and is vertically supported on the first support included between the two facing vertical struts. Preferably, each vertical strut is composed of a plurality of continuous vertical strut segments (formed by vertical thin plates of engineered wood), and the plurality of continuous vertical strut segments are aligned and rigidly connected to each other through vertical connectors (formed by vertical thin plates of engineered wood). The plurality of continuous vertical strut segments adhere to the vertical column surfaces of adjacent continuous vertical strut segments, or are aligned and rigidly connected to each other through complementary recessed staggered step portions defined on the adjacent ends of two continuous vertical strut segments that overlap and adhere to each other.

[0055] According to an embodiment of the present invention, at least one vertical structural element includes at least one intermediate structural node located in its middle portion. The intermediate structural node is spanned by the vertical strut without interrupting the vertical strut, and the vertical structural element extends above and below the intermediate structural node.

[0056] Accordingly, the structural node can be placed at the middle position of the vertical structural element, not just the extreme position, maintaining the structural continuity of the vertical struts above and below the structural node, and transferring not only vertical loads but also bending loads, shear loads, and torsional loads through the structural node of the vertical structural element.

[0057] It is also proposed that at least one structural node is spanned by at least one horizontal structural element without interrupting the horizontal structural element and without interrupting the vertical strut. The horizontal structural element includes portions protruding from the vertical structural element on at least two different sides of the vertical structural element. The at least two different sides can be opposite sides (such as the left and right sides) of the vertical structural element, or two consecutive sides (such as the front and left sides), and preferably three sides or four sides of the vertical structural element.

[0058] Accordingly, at least one horizontal structural element spans the structural node without interruption, transferring the load from one protrusion to another through the structural node, thereby improving the structural performance of the horizontal structural element.

[0059] The above-mentioned continuous vertical strut segments are rigidly connected to each other, for example, by the following components:

[0060] The end faces of the continuous vertical strut segments are attached to each other by an adhesive;

[0061] A vertical connecting member; or

[0062] A vertical connecting member that partially overlaps and is attached to two continuous vertical strut segments; or

[0063] A vertical connecting member that partially overlaps and is attached to two continuous vertical strut segments through complementary recessed staggered stepped portions; or

[0064] A vertical connecting member that is included between two continuous vertical strut segments and is connected to a first spacer rigidly attached to the continuous vertical strut segments; or

[0065] Complementary recessed staggered stepped portions are defined on the ends of two continuous vertical strut segments that overlap and are attached to each other.

[0066] Accordingly, the connection between the vertical strut segments can be achieved through a vertical connecting member that simultaneously adheres to the ends of two continuous vertical strut segments of the same vertical strut and / or is connected to a first spacer that is simultaneously connected to the ends of two continuous vertical strut segments. In some cases, the first spacer can also act as a vertical connecting member. In any case, the connection between the continuous vertical strut segments should be a rigid connection. The vertical connecting member can be formed by vertical thin plates of engineered wood, metal, and / or carbon fiber.

[0067] Alternatively, the connection between the vertical strut segments can be achieved by directly bonding two overlapping portions of the continuous vertical strut segments connected to each other, and the overlapping portions include complementary recessed staggered stepped portions that define the attachment portions. Each recessed staggered stepped portion is defined in a vertical plane parallel to the main surface of the vertical strut, increasing the attachment area where the two connecting elements are attached together by the adhesive.

[0068] Preferably, each vertical strut segment is included between two structural nodes, and the attachment between the continuous vertical strut segments is generated in the portion of the vertical structural element that defines the structural node.

[0069] It is also proposed that at least a part of the vertical connecting member may include one or a plurality of recessed staggered stepped portions, and these stepped portions are complementary to and attached to the recessed staggered stepped portions included in the continuous vertical strut segments connected to each other through the vertical connecting member. This connection provides a more uniform load distribution, increases the connection surface, provides not only a vertical connection surface on each stepped portion but also a horizontal connection surface, and increases the strength of the connection. While the vertical surface ensures the separation between components, the horizontal surface can transfer compressive loads.

[0070] When two consecutive vertical strut segments have the same cross-sectional area, this connection also allows the two consecutive vertical strut segments and the vertical connecting member to be flush.

[0071] The consecutive strut segments may have the same cross-sectional area, or preferably have different cross-sectional areas to accommodate the vertical loads supported by each strut segment. Strut segments closer to the foundation support greater vertical loads compared to those closer to the uppermost structural plate layer. Therefore, it is proposed to always use strut segments with a cross-sectional area equal to or smaller than that of the same vertical structural element placed below.

[0072] A plurality of horizontal structural elements may be supported on the same structural node, and each horizontal structural element includes at least one second support supported on at least one first support of the structural node.

[0073] In this case, the horizontal structural elements supported on the same structural node will be rigidly connected to each other through upper connecting members and / or lower connecting members.

[0074] The upper connecting member is at least partially included in the hollow interior of the vertical structural element, at least partially overlaps and attaches to all the horizontal structural elements supported in the structural node to transfer horizontal traction loads between the upper horizontal plates of the connected horizontal structural elements. Preferably, the upper connecting member overlaps to the ends of all converging horizontal structural elements and adheres to the upper horizontal plates of the converging horizontal structural elements.

[0075] The lower connecting member is at least partially contained in the hollow interior of the vertical structural element, is placed between the converging horizontal structural elements and is in direct contact with them or in contact with them through an intervening hardened adhesive, and / or at least partially overlaps and attaches to all the horizontal structural elements supported in the structural node, and / or at least partially overlaps and attaches to the second supports of all the horizontal structural elements supported in the structural node to transfer horizontal compressive loads between the lower horizontal plates of the connected horizontal structural elements.

[0076] The lower connecting member can be formed of engineered wood, metal, or can be a solid block of hardened adhesive.

[0077] For example, the lower connector can be placed between converging horizontal structural elements and in close contact therewith to transfer horizontal compressive loads therebetween. For example, it can be installed between opposite ends of the converging horizontal structural elements in the form of a block or an inverted truncated cone, such that the lower connector can be compressed between the opposite ends. It is contemplated to create the close contact through an intervening hardening adhesive.

[0078] Similar to the upper connector, the lower connector can also at least partially overlap with all the horizontal structural elements supported in the structural node, be located below and attached to these horizontal structural elements to transfer horizontal compressive loads therebetween.

[0079] When the first support is simultaneously attached to all the second supports of all the horizontal structural elements supported at the same structural node, the lower connector can also be the first support of the vertical structural element, transferring horizontal compressive loads between the converging horizontal structural elements.

[0080] For example, the upper connector and / or the lower connector can include a plurality of radially horizontal connecting arms that surround a central portion contained within the hollow interior of the vertical structural element, with each radially horizontal connecting arm connected to one horizontal structural element, or each radially horizontal connecting arm attached to one horizontal structural element through complementary recessed staggered stepped portions.

[0081] The upper connector and / or the lower connector can be formed of engineered wood, metal, and / or carbon fiber.

[0082] When the upper connector or the lower connector includes a plurality of radially horizontal connecting arms and is formed of engineered wood, the connector preferably includes a plurality of overlapping engineered wood layers with different panel orientations bonded together.

[0083] For example, the horizontal structural element can be a beam or an I-beam. At each structural node that supports the beam or the I-beam, there is a region that includes at least one second support, and at least one second support is inserted into the hollow interior of the vertical structural element.

[0084] The beam or the I-beam can be a beam passing through the structural node, and the second support formed in the middle region of the beam is inserted into the hollow interior of the vertical structural element. The beam can pass through a plurality of aligned structural nodes of different vertical structural elements, and the beam has a plurality of second supports that are defined in several middle regions inserted into the hollow interiors of different vertical structural elements. In particular, if the space between consecutive aligned vertical structural elements is enclosed by vertical wall panels, a beam (e.g., less than 1 m or less than 0.5 m) supported on consecutive closely spaced aligned vertical structural elements can be regarded as a structural wall.

[0085] The I-beam provides the best utilization of materials because the I-beam is stronger, more durable, uses less material and is thus lighter and cheaper compared to other types of beams.

[0086] Preferably, the second spacer of the beam or I-beam is one or more central vertical plates, that is, the main surfaces of the slats are in a vertical position, connecting the upper horizontal plate and the lower horizontal plate together, and the main surfaces of the upper horizontal plate and the lower horizontal plate are mostly in a horizontal position.

[0087] Alternatively, the second spacer of the beam or I-beam can be formed, for example, by the following components: overlapping horizontal slats (such as several stacked horizontal plates), and / or several stacked horizontal plates with oriented fibers parallel to each other, and / or several stacked horizontal plates with oriented fibers distributed in the vertical direction in a continuous sheet; or, it can be formed by triangular strips of engineered wood or metal.

[0088] The beam or I-beam can be a post-stressed beam, including at least one post-stressed cable between its opposite ends. Optionally, a plurality of aligned continuous beams can be post-stressed beams, including at least one continuous post-stressed cable passing through all the continuous beams.

[0089] The opposite ends of the at least one beam hold at least one post-stressed cable in an upper position adjacent to the upper horizontal plate, and the central region of the at least one beam between the opposite ends holds at least one post-stressed cable in a lower position adjacent to the lower horizontal plate.

[0090] According to this solution, the post-stressed cable covers the entire longitudinal length of the beam from one end to the opposite end, the post-stressed cable is held under tension defining a polygonal or arched shape, the central region of the post-stressed cable is adjacent to the central region of the lower horizontal plate of the beam, and the opposite ends of the post-stressed cable are adjacent to the ends of the upper horizontal plate of the beam, increasing the overall load-bearing capacity of the beam.

[0091] Optionally, a plurality of continuous beams are post-stressed beams, including at least one continuous post-stressed cable passing through all the continuous beams. The opposite ends of each beam hold at least one post-stressed cable in an upper position adjacent to the upper horizontal plate, and the central region of each beam between the opposite ends holds at least one post-stressed cable in a lower position adjacent to the lower horizontal plate, allowing the same post-stressed cable to be used for post-tensioning a plurality of continuous beams.

[0092] Alternatively, the plurality of continuous beams are post-stressed beams, each beam including at least one cable sleeve, opposite ends of each beam holding at least one cable sleeve in an upper position adjacent to the upper horizontal plate, and a central region of each beam being located between the opposite ends and holding at least one cable sleeve in a lower position adjacent to the lower horizontal plate, wherein each cable sleeve of each beam is connected to the cable sleeves of successive beams of the plurality of continuous beams by sleeve connectors, and wherein the plurality of continuous beams includes at least one continuous post-stress cable that passes through corresponding cable sleeves along all of the continuous beams, the cable sleeves being connected to each other by the sleeve connectors.

[0093] In this way, the cable sleeves can be pre-installed on each beam, and once the beams are installed, the cable sleeves can be connected to each other by the sleeve connectors, and then, the post-stress cable can be inserted through the cable sleeves and post-tensioned.

[0094] Alternatively, the horizontal structural element can be a plate having a region including at least one second support inserted into a hollow interior of a vertical structural element, and at each structural node supporting the plate, the plate includes at least one vertical through-hole adjacent to the second support, and a vertical strut of the vertical structural element passes through the vertical through-hole.

[0095] The plate can be supported simultaneously at several structural nodes of different vertical structural elements, the plate including portions having at least one second support inserted into the hollow interior of each vertical structural element. The plate will include at least one vertical through-hole adjacent to each second support, and a vertical strut of the vertical structural element passes through the vertical through-hole.

[0096] In this case, the second spacer can include one or several central vertical plates or a plurality of central vertical plates arranged in an orthogonal direction and / or rigid foam connecting the upper and lower horizontal plates. The central vertical plate is a plate whose main surface is in the vertical direction. Alternatively, these second spacers can also be stacked horizontal plates in one direction or two orthogonal directions.

[0097] According to one embodiment, the plate can be a post-stressed plate including a plurality of plate post-stress cables arranged parallel to each other or in two intersecting directions.

[0098] Alternatively, a plurality of aligned continuous plates can be post-stressed plates including a plurality of continuous plate post-stress cables arranged parallel to each other or in two intersecting directions, and at least a portion of the plurality of plate post-stress cables pass through all of the continuous plates.

[0099] Preferably, in at least one structural node, the upper and lower horizontal plates of at least one horizontal structural element connected to the structural node are spaced apart from the vertical struts of the vertical structural element by a clearance distance, and the first and second supports are configured to reduce or avoid the transfer of bending forces, thereby forming a hinge joint between the horizontal structural element and the vertical structural element. In this case, the vertical load is transferred from the horizontal structural element to the vertical structural element through the second support that overlaps and supports on the first support of the vertical structural element, but no rigid attachment is provided, thus avoiding the transfer of bending forces.

[0100] When the horizontal structural element is attached to the upper and lower connectors, the upper and lower connectors are also spaced apart from the vertical struts by the clearance distance, thereby avoiding the transfer of bending forces therethrough.

[0101] Those skilled in the art will be fully aware of a variety of different connections that will avoid the transfer of bending forces. For example, in order to avoid the transfer of bending forces, the first and second supports provide the transfer of forces in the vertically downward direction, but completely or mostly prevent or preclude the transfer of forces in the vertically upward or horizontal directions.

[0102] Alternatively, in at least one structural node, the upper and lower horizontal plates of at least one horizontal structural element connected to the structural node are respectively connected to opposite vertical sides of the vertical strut, transferring the bending force to the vertical strut and forming a rigid connection between the horizontal structural element and the vertical structural element. The connection can be produced directly, or through the upper and / or lower connectors and / or through a hardened adhesive filling the clearance distance.

[0103] When the horizontal structural element is connected to the upper and lower connectors, the upper and lower connectors can also be attached to opposite vertical sides of the vertical strut, transferring a pair of opposite horizontal forces and transferring the bending force to the vertical structural element.

[0104] In this case, the lower horizontal plate or the lower connector attached to the lower horizontal plate will be pressed against the vertical side of one or several vertical struts of the vertical structural element, transferring horizontal pressure thereto, and the upper horizontal plate or the upper connector connected to the upper horizontal plate will be pressed against another vertical side of one or several vertical struts, the vertical side being opposite to the vertical side attached to the aforementioned lower horizontal plate, transferring a horizontal compressive force that is opposite to and higher than the aforementioned horizontal compressive force thereto. The pair of opposite horizontal forces transfers the bending force to the vertical strut, producing a rigid attachment between the horizontal structural element and the vertical structural element.

[0105] In this case, the first and second supports can be configured to avoid transferring bending forces or configured to transfer bending forces.

[0106] In some examples according to this embodiment, the opposing vertical sides receiving the horizontal compressive force are vertical sides facing each other within the hollow interior of a vertical structural element, are vertical sides of two different vertical struts, or are opposing vertical sides of the same vertical strut, or are vertical sides of different vertical struts, and the vertical sides are located on the outer periphery of the vertical structural element.

[0107] According to one embodiment, at least one horizontal structural element can be supported simultaneously at a plurality of structural nodes of different vertical structural elements.

[0108] The horizontal structural elements of the same lamina can be laterally adjacent plates. These adjacent plates can be connected to each other, for example, by attachment of the following components:

[0109] The peripheral region of the upper horizontal plate of one plate is directly attached in a stacked manner to the peripheral region of the upper horizontal plate of another laterally adjacent plate through complementary staggered steps or through intervening joint connectors to transfer the horizontal load; and / or

[0110] The peripheral region of the upper horizontal plate of one plate is directly attached in a stacked manner to the peripheral region of the upper horizontal plate of another laterally adjacent plate through complementary staggered steps or through intervening joint connectors to transfer the horizontal traction load, and the peripheral region of the lower horizontal plate of one plate is attached to the peripheral region of the lower horizontal plate of another laterally adjacent plate to transfer the horizontal load.

[0111] Accordingly, different horizontal structural elements (usually different plates) of the same lamina can be attached to each other laterally to form a continuous lamina. The attachment between adjacent horizontal structural elements provides structural continuity, and due to the load transfer between them, the performance of the horizontal structural elements is increased. When the horizontal structural elements are plates, the connection can be generated directly through the peripheral regions of the adjacent plates or through the joint connectors connecting the adjacent plates.

[0112] The plate can be connected to the adjacent plates only through the peripheral regions at its opposite ends, thereby obtaining a plate having unidirectional structural continuity with the adjacent plates. Alternatively, the plate can be connected to the adjacent plates through the peripheral regions on the four sides of the plate, obtaining bidirectional structural continuity with the adjacent plates.

[0113] An additional embodiment is proposed regardless of whether the horizontal structural element is a plate or a beam, which can be implemented independently of the above embodiments (i.e., the vertical structural element is different from the above embodiments, or the connection between the horizontal structural element and the vertical structural element is different from the above connection), or can be freely combined with any proposed embodiment to provide different solutions, which can be used as the basis for divisional applications. This embodiment is directed to an engineered wood structure system formed by engineered wood members, including:

[0114] A plurality of horizontal structural elements, separated by a gap distance, each horizontal structural element including at least one second support, which is supported and vertically overlapped on at least one first support of a vertical structural element. Each horizontal structural element is composed of an upper horizontal plate and a lower horizontal plate, which face each other, are vertically separated from each other, and are rigidly connected to each other by a second spacer included between the upper horizontal plate and the lower horizontal plate;

[0115] At least one plate segment, placed between the horizontal structural elements and supported on the horizontal structural elements, which covers the gap distance between the horizontal structural elements and defines a ply. The plate segment is composed of an upper horizontal plate and a lower horizontal plate, which face each other, are vertically separated from each other, and are rigidly connected to each other by a third spacer included between the upper horizontal plate and the lower horizontal plate.

[0116] The third spacer can have the same possible embodiments as the above-mentioned second spacer.

[0117] At least one plate segment can be supported on the horizontal structural element by a third support included in the plate segment. The third support can be:

[0118] The peripheral area of the upper horizontal plate of the plate segment, directly attached to the upper horizontal plate of the surrounding horizontal structural element through complementary staggered steps or through a joint connector to transfer horizontal traction loads; and / or

[0119] The peripheral area of the upper horizontal plate of the plate segment, directly attached to the upper horizontal plate of the surrounding horizontal structural element through complementary staggered steps or through a joint connector to transfer horizontal traction loads, and the peripheral area of the lower horizontal plate of the plate segment, directly attached to the peripheral area of the lower horizontal plate of the surrounding horizontal structural element through complementary staggered steps or through an intervening connector to transfer horizontal compression loads; and / or

[0120] The peripheral area of the upper horizontal plate of the plate segment, directly attached to the upper horizontal plate of other adjacent plate segments through complementary staggered steps or through a joint connector to transfer horizontal traction loads, and the plate segment is supported on at least one horizontal structural element;

[0121] The peripheral region of the upper horizontal plate of the plate segment is directly attached to the upper horizontal plate of other adjacent plate segments through complementary staggered step portions or through joint connectors to transfer horizontal traction loads. The plate segment is supported on at least one horizontal structural element. The peripheral region of the lower horizontal plate of the plate segment is directly attached to the peripheral region of the lower horizontal plate of the adjacent plate segment through complementary staggered step portions or through intervening connectors to transfer horizontal compression loads.

[0122] Each plate segment can be attached to the horizontal structural element by vertically overlapping and connecting to a third support of the horizontal structural element. For example, the third support can be a region or a reinforced region of the lower horizontal plate of the plate segment, or an exposed portion of the downward-exposed surface of the plate segment, an overlapping third spacer attached to the upper horizontal plate of at least one horizontal structural element or the upward-exposed surface of the horizontal structural element.

[0123] When the horizontal structural element is a plate, the upper horizontal plate of the intervening plate segment can be flush with the upper horizontal plate of the flat plate. This connection can be produced by partially overlapping peripheral regions of the plates connected to each other (e.g., through staggered step portions).

[0124] The plate segment can be connected to the adjacent plate only through the peripheral regions at its opposite ends, thereby obtaining a plate segment having one-way structural continuity with the adjacent plate. Optionally, the plate segment can be connected to the adjacent plate through the peripheral regions on the four sides of the plate segment, thereby obtaining two-way structural continuity between the plate segment and the adjacent plate.

[0125] When the horizontal structural element is a beam, the upper horizontal plate of the intervening plate segment can overlap and be attached to the upper horizontal plate of the beam, and preferably, the upper horizontal plates of adjacent plate segments placed on opposite sides of the same beam can be connected to each other to transfer traction loads between the adjacent plate segments.

[0126] In this case, the plate segment can be connected to the adjacent plate segment only through the peripheral regions at its opposite ends, thereby obtaining a plate segment having one-way structural continuity with the adjacent plate segment. Optionally, the plate segment can be connected to the adjacent plate segment through the peripheral regions on the four sides of the plate segment, thereby obtaining two-way structural continuity between the plate segment and the adjacent plate segment.

[0127] The upper horizontal plate of the plate segment is directly connected to the upper horizontal plate of the adjacent plate segment through complementary overlapping staggered step portions provided in the peripheral region of the upper horizontal plate or through a connector to transfer horizontal traction loads therebetween, and / or the lower horizontal plate of the plate segment is directly connected to the lower horizontal plate of the adjacent plate segment through complementary overlapping staggered step portions provided in the peripheral region of the lower horizontal plate or through a connector to transfer horizontal compression loads therebetween.

[0128] The sheet section can be supported on the upper horizontal plate of the horizontal structural element by means of a third support defined in the downward-facing surface of the upper horizontal plate of the sheet section, and / or can be supported on the lower horizontal plate of the horizontal structural element by means of the third support and / or be supported on the second spacer of the horizontal structural element.

[0129] When the sheet section is supported on a beam, the sheet section can be placed above the beam, and the third support is defined in the lower horizontal plate or the third spacer of the sheet section, and the third support is supported on and attached to the upper horizontal plate of the beam.

[0130] Alternatively, the beam can be at least partially embedded in the structural slab layer to reduce the overall thickness, and adjacent sheet sections located on opposite sides of the beam can be directly connected to each other by providing complementary overlapping and staggered stepped portions in the peripheral region of the upper horizontal plate or by means of connectors to transfer horizontal traction loads therebetween. The lower horizontal plate of the sheet section can also be directly attached to the lower horizontal plate of an adjacent sheet section by providing complementary overlapping and staggered stepped portions in the peripheral region of the lower horizontal plate or by means of connectors to transfer horizontal compressive loads therebetween. The connectors can be integrated in the beam or can pass through the beam.

[0131] The construction of the beam, the sheet, the sheet section and their connection through the peripheral region can be implemented independently of the connection between the horizontal structural element and the vertical structural element, and thus these features can form the basis for a divisional application.

[0132] Preferably, the vertical structural element has a square or rectangular cross-section defined by two vertical struts, each strut covering two corners of the vertical structural element, thus defining two entrances to the hollow interior of the structural node. Two different horizontal structural elements can be inserted into the hollow interior through the entrances, or a single horizontal structural element can pass through the hollow interior and protrude through the two entrances.

[0133] Alternatively, the vertical structural element is defined by three vertical struts, one vertical strut covering two corners of the vertical structural element, and the other two vertical struts are placed at the remaining two corners of the vertical structural element, defining three entrances to the hollow interior of the structural node.

[0134] Optionally, the vertical structural element is defined by four vertical struts placed at the four corners of the vertical structural element, and the vertical struts define four entrances to the hollow interior of the structural node.

[0135] There may be tolerance gaps between some connected engineered wood members, or when no shear load is transmitted through the hardened adhesive, there is a tolerance gap of up to 25 mm therebetween filled with the hardened adhesive, or when the shear load is transmitted through the hardened adhesive, there is a tolerance gap of up to 1 mm therebetween filled with the hardened adhesive.

[0136] It should be understood that the reference geometric positions (such as parallel, perpendicular, tangent, etc.) allow the theoretical positions defined by the term to deviate by ±5°.

[0169] On the drawings, the surfaces coated with adhesive are shaded. Detailed Description

[0170] From the following detailed description of the embodiments with reference to the drawings, the foregoing and other advantages and features will be more fully understood, and these descriptions are illustrative and not restrictive.

[0171] According to one embodiment, the engineered wood structure system of the present invention can be used to construct multi-story buildings having multiple stacked structural panel layers (e.g., between five and twenty structural panel layers), wherein each vertical structural element 10 is an independent vertical structural element connected to two, three, or four horizontal structural elements 120, 20, and the horizontal structural elements 120, 20 converge in the form of beams 20 at the structural nodes of the vertical structural elements 10 of each structural panel layer. In these buildings, the structural nodes are preferably rigid nodes that connect the beams and the vertical structural elements together. Similarly, the horizontal structural elements can be one or several plates 120 connected to the structural nodes of the vertical structural elements 10.

[0172] Alternatively, the building can include rigid elements that cover the entire height of the building, such as a rigid core (usually a staircase or elevator enclosure) or diagonal elements that connect some of the structural nodes of different floors.

[0173] The proposed engineered wood structure system can also be used to construct multi-story buildings having structural walls (e.g., balloon or platform frame buildings), where the structural walls are formed by a series of parallel-aligned vertical structural elements that support a continuous horizontal structural element in the form of a beam or a plate.

[0174] As Figure 1B shown, the proposed engineered wood structure system also allows for a hybrid structure that combines structural walls (formed by aligned vertical structural elements that support a beam) and independent vertical structural elements. In this case, the structural wall can serve as a rigid core for the independent vertical structural elements, and in this case, the rigidity of the structural nodes is optional.

[0175] In Figure 1A it, an example of a partially constructed building is shown, where all horizontal structural elements are horizontal beams 20 that are orthogonal to each other, defining a square matrix of beams 20 for each structural panel layer.

[0176] As Figure 2A and Figure 2B shown, each beam 20 includes an upper horizontal plate 21 and a lower horizontal plate 22 that are parallel to each other, spaced apart by a certain distance, and connected to each other by a second spacer 23. In this embodiment, the second spacer is two parallel central vertical plates that are perpendicular to and adhered to the upper horizontal plate 21 and the lower horizontal plate 22, thus providing an I-beam 20 with double central vertical plates. This shape has an optimal relationship between load resistance, cost, and weight.

[0177] In this embodiment, the upper horizontal plate 21 and the lower horizontal plate 22 (which mainly resist loads parallel to their main longitudinal direction) are formed of laminated veneer lumber.

[0178] The two parallel central vertical plates each have two ends 23a. Each end 23a (formed of a durable engineered wood such as plywood in this example) is adjacent to one of the vertical structural elements 10 of the support beam 20, and the remaining portions of the two parallel central vertical plates between the two ends 23a are formed of a cheaper and more durable engineered wood (such as oriented strand board) in this example because the load on this central portion is much less than the load in the ends 23a.

[0179] For example, as Figure 4 and Figure 5A shown, each vertical structural element 10 includes a first support 11 for each horizontal structural element to be supported on the vertical structural element 10, and the horizontal structural element includes a second support configured to be supported on the first support 11.

[0180] When a reduced load is transferred from the horizontal structural element to the vertical structural element 10, for example when the beam 20 is supported on a plurality of aligned vertical structural elements 10, for example, as Figure 11 shown, the beam 20 can be supported on the first support 11 of each vertical structural element 10 by the second support defined in the lower horizontal plate 22, compressing the lower horizontal plate 22 in the vertical direction, which is sub - optimal but sufficient to resist such a reduced load.

[0181] When the load transferred from the beam 20 to the vertical structural element 10 is large, for example, when a 3m to 8m long beam is supported only at its two ends on the vertical structural element 10, the ends 23a of the two central vertical plates of each beam 20 are vertically supported on the first support 11, transferring the vertical load from the beam 20 to the vertical structural element 10 in a direction parallel to the main surface of the central vertical plate, which is optimal for load transfer.

[0182] Since this load transfer generates compressive and shear loads on the ends 23a of the central vertical plates, the ends 23a are preferably made of an engineered wood (such as plywood) including veneer fibers in different directions.

[0183] In the example shown in the figure, each first support 11 may include two vertical and parallel plates perpendicular to the central vertical plate to be supported, and each plate includes a central notch between two horizontal support regions. Each support region is intended to contact one of the two central vertical plates of the beam 20 to be supported, and the central notch is intended to receive the end 22a of the lower horizontal plate 22 of the beam 20 supported on the first support 11 to prevent contact between the end 22a and the first support 11. Optionally, the first support 11 is an engineered wood block attached to a vertical post.

[0184] According to the embodiment shown in the figure, each vertical structural element 10 includes a plurality of vertical struts 12 that are continuous along the entire longitudinal direction of the building. The vertical struts 12 are separated by vertical structural element spacers (i.e., the first spacers 14) that are placed between the struts 12 in the horizontal direction and adhered to the struts 12, thereby creating a hollow vertical structural element 10. The spacing between the struts 12 of the vertical structural element 10 allows the ends of all the beams converging on the vertical structural element 10 (including the ends 23a of the corresponding central vertical plates) to be inserted into the space between the struts 12 of the vertical structural element 10, thereby allowing the vertical continuity of the struts 12 around the ends of the beams 20.

[0185] The first supports 11 are also included between the struts 12 and adhered to the struts. The first supports 11 are located between the struts 12 within the hollow vertical structural element and connected to the struts, thereby allowing the transfer of loads from the beams 20 to the vertical structural element 10 in the region near the geometric center of the vertical structural element 10, thereby reducing the bending loads generated on the vertical structural element 10.

[0186] The loads transferred from the beams 20 to the vertical structural element 10 through the first supports 11 are concentrated on the struts 12, accumulated from multiple structural plate layers, and conducted to the foundation supporting the vertical structural element 10.

[0187] Multiple beams 20 of the same structural plate layer converging on the same vertical structural element 10 are connected to each other at least through the upper connectors 40 and the lower connectors 50, as Figures 5B to 8B shown.

[0188] The upper connectors 40 are flat horizontal thin plates, including as many horizontal connecting arms 41 as the beams 20 of the same structural plate layer converging on the vertical structural element 10. The angular distribution of the horizontal connecting arms 41 is consistent with the angular distribution of the beams 20 converging on the vertical structural element 10.

[0189] Each horizontal connecting arm 41 is adhered to the end 21a of the upper horizontal plate 21 of a beam 20 supported on the vertical structural element 10. The upper connectors 40 transfer loads between the upper horizontal plates 21 of all the beams 20 converging on the vertical structural element 10.

[0190] According to a preferred embodiment shown in the figure, the end 21a of each upper horizontal plate 21 and the horizontal connecting arm 41 adhered thereto include complementary recessed staggered stepped portions that are coupled and adhered to each other, and each stepped portion is a plane parallel to the upper main surface of the upper horizontal plate 21. The connection through the recessed staggered stepped portions results in a distributed transfer of the load and also allows the upper connecting member 40 to be flush with the upper main surface of the upper horizontal plate 21 of the beam 20. The upper connecting member 40 is preferably formed of engineered wood (such as plywood) including panel fibers in different directions.

[0191] The lower connecting member 50 includes a tapered block, such as an inverted truncated pyramidal shape, which is tightly inserted in a descending direction between the ends 22a of the lower horizontal plates 22 of the beams 20 that converge on the same vertical structural element 20 in the same structural plate layer. The lower connecting member 50 transfers the load between the lower horizontal plates 22 of the converging beams 20 in the same structural plate layer.

[0192] Each lower horizontal plate 22 may include a reinforcing member that is adhered to the end 22a of the beam 20 between the two central vertical plates, increasing the thickness and load resistance of the end 22a of the lower horizontal plate 22 in contact with the lower connecting member 50.

[0193] As Figure 5B 、 Figure 6A and Figure 8A shown, between the ends of the converging beams 20, the lower connecting member 50 is a tapered block that is inserted into the center of the hollow vertical structural element 10 defined between the vertical struts 12 constituting the vertical structural element 10, and the lower connecting member 50 is compressed between the ends 22a of the lower horizontal plates 22 of the converging beams 20 in the same structural plate layer.

[0194] Optionally, each beam 20 may also be connected to the vertical structural element 10 by at least one vertical connecting member 60 formed of vertical engineered wood veneers, as Figures 7A to 8B shown.

[0195] Below and above the structural node, each vertical connecting member 60 is adhered to a vertical strut surface 10a of a vertical strut 12 of the vertical structural element 10.

[0196] The vertical connecting member 60 transfers shear, bending, and torsional loads from the beam 20 to the struts 12 of the vertical structural element 10 and is preferably made of engineered wood (such as plywood) including panel fibers in different directions.

[0197] Each strut 12 of a single continuous vertical structural element 10 is generally composed of a plurality of continuous vertical strut segments 13 that are rigidly connected to each other, and the height of each vertical strut segment 13 is the same as the distance between the continuous structural plate layers.

[0198] According to Figure 5B and Figure 5C In the embodiment shown, two consecutive vertical pillar segments 13 forming the same pillar 12 include complementary recessed staggered step portions at their ends, and these step portions are coupled and adhered to each other, thereby providing vertical continuity and vertical transfer of load.

[0199] According to Figures 7A to 8B In an alternative embodiment shown, two consecutive vertical pillar segments 13 forming the same pillar 12 are connected to each other by a vertical connector 60, and the vertical connector 60 is adhered to the vertical pillar surface 10a of the vertical pillar segment 13 placed below the beam 20 and the vertical pillar surface 10a of the vertical pillar segment 13 placed above the beam 20.

[0200] Preferably, each said vertical pillar segment 13 is connected to the vertical connector 60 by complementary recessed staggered step portions parallel to the vertical pillar surface 10a included in the vertical pillar segment 13 and the vertical connector 60 to provide distributed load transfer. The complementary recessed staggered step portions provide vertical continuity and vertical transfer of load.

[0201] In some cases, it is preferable to connect vertical pillar segments 13 having different cross-sectional areas (usually the lower vertical pillar segments 13 have larger cross-sectional areas to withstand larger cumulative loads) together, thereby producing a vertical structural element 10 with an increased cross-section and increased load resistance.

[0202] All embodiments described regarding the connection between one or more beams 20 and a structural node of a vertical structural element 10 are also applicable to the connection between one or more plates 120 and a structural node of the vertical structural element 10, such as as Figure 7A and Figure 7B shown.

[0203] In these examples, the plate 120 includes as many (four in this example) square vertical through-holes in its central region as the vertical pillars where the vertical structural element is supported, and branch portions are defined between the through-holes, and the branch portions are received in the hollow interior of the vertical structural element. Obviously, when several plates 120 are supported at the same structural node, the number of vertical through-holes on each plate 120 is only a part of the total number of vertical pillars of the supported vertical structural element, and the through-holes will be adjacent to the edges or corners of the plate 120.

[0204] In Figure 7A and Figure 7BIn the example shown, the second spacer 23 of the sheet 120 is an array of cross ribs, and the second support includes regions where the second spacer is more densely distributed. In this example, the upper plate of the horizontal structural element also includes a reinforcement defined by a thickened portion of the upper plate, which is consistent with the branch portion defined between the vertical through holes, for improving the horizontal load resistance of the upper plate in the said region.

[0205] A frame defined between four orthogonal beams 20 of the same structural plate layer is covered by a sheet segment 30 supported on the beams 20.

[0206] Each sheet segment 30 includes an upper horizontal plate 33 and a lower horizontal plate 34 that are parallel to each other, and are connected to each other by first ribs 31 that are parallel to each other and second ribs 32 that are perpendicular to the first ribs 31. The first ribs 31 and the second ribs 32 are between the upper horizontal plate 33 and the lower horizontal plate 34.

[0207] The upper horizontal plate 33 is larger than the footprint of the hollow space defined between the beams 20 that support the sheet segment 30. The upper horizontal plate 33 includes a peripheral region that is supported on and adhered to the upper horizontal plate 21 of the beams 20.

[0208] The upper horizontal plate 33 is connected to the upper horizontal plate 33 of an adjacent sheet segment 30, for example, by complementary recessed staggered step portions provided in the peripheral regions of the two upper horizontal plates 33 of adjacent sheet segments 30 that are connected to each other, or by an upper thin plate connector 36 that is adhered to the peripheral regions of the two upper horizontal plates 33 of adjacent sheet segments 30 that are connected to each other. In this case, the upper thin plate connector 36 is a slender slat that connects the peripheral regions of the two upper horizontal plates 33 together. Preferably, the slender slat is inserted into the recessed region of the peripheral region and is flush with the upper horizontal plate 33, as shown in FIG. 1.

[0209] The lower horizontal plate 34 is equal to or smaller than the footprint of the hollow space defined between the beams 20 that support the sheet segment 30. The lower horizontal plate 34 includes a peripheral region that is adhered to the surrounding beams 20 by a lower thin plate connector 35, preferably adhered to the surrounding central vertical plate of the beams 20. In this example, the lower thin plate connector is a slat that is adhered to the peripheral region of the lower horizontal plate 34, for example, by complementary recessed staggered step portions that adhere to each other and adhere to the central vertical plate.

[0210] In the present embodiment, at least one central vertical plate of the beam 20 is two parallel central vertical plates, including a compression structure therebetween to transfer loads between lower thin plate connectors 35 of two different plate segments adhered to both sides of the same beam 20.

[0218] Typically, three sheet segments 30a, 30b, and 30c are installed adjacent to each other, and the sheet segments 30a, 30b, and 30c are supported on the surrounding beam 20 through the peripheral region of the upper horizontal plate 33, and the corresponding lower horizontal plate portions are connected to each other through the lower thin plate joint.

One cable holder is located at the center of the beam, holding the post-tensioned cable 70 at its lower end, and two cable holders are located at the opposite ends of the beam, holding the post-tensioned cable 70 at their respective upper ends, defining a V-shaped post-tensioned cable 70.

[0224] Moreover, a plurality of continuous beams 20 can include at least one continuous post-tensioned cable 70 passing through all the continuous beams 20. Optionally, the continuous post-tensioned cable 70 can be inserted into a cable sleeve pre-installed on each beam 20, and the cable sleeves of all the continuous beams 20 are connected to each other through sleeve connectors.
