Description

Technical Field

[0001] This application relates to wall elements, unit construction systems, and methods of using the above elements. This application is in the field of structural building materials.

Background Art

[0002] Due to the rapid growth in many regions around the world driving the need for housing and other functional buildings, it has become essential to use modern methods and materials for the purpose of accelerating the construction speed, reducing the weight of buildings and building materials, extending the average lifespan, and strengthening buildings against earthquakes and other severe natural or unnatural hazards. To address these, innovative solutions based on the use of modern methods and modern building materials are required, resulting in reduced building weight, shortened construction time, improved durability, and all of these ultimately combined to reduce the construction cost of buildings.

[0003] Currently, there are several types of materials and systems used in construction. The most commonly used are stone, wood, bricks, (reinforced) concrete, metal, hollow concrete blocks, and plaster, although other materials are also used. More specifically, these are materials used even for outer walls or slabs between floors. When the rigidity of weaker materials is low, there is compensation for the amount (thickness or volume) used to withstand the increasing weight as the floors of the building increase.

[0004] One of the objectives in civil engineering is the reduction of the weight (weight reduction) of structures and buildings. To achieve this objective, engineering has innovated and provided composite materials that are lightweight while maintaining high resistance.

[0005] Those skilled in the art know that the lighter a structure is, the less energy it absorbs from earthquakes, and therefore the less impact earthquakes have on the building. In other words, reducing the weight of a building (making it lighter) means providing improved safety against earthquakes.

[0006] The use of traditional, older construction materials such as bricks, clay blocks, and cement blocks not only increases the magnitude of the building's dead load but also increases energy consumption, which can be considered an energy waste. Furthermore, the low assembly speed and large amount of building rubble resulting from the use of such materials are just some of the other problems arising from the use of such traditional materials that impact the environment and the economy.

[0007] Furthermore, increased building weight leads to higher construction costs, which in turn drives up the overall building cost. These issues can be seen as part of the many challenges facing the construction sector.

[0008] Many construction materials are available individually for assembly at the construction site, while others are pre-fabricated and assembled in a manufacturing plant before being transported to the construction site. Further mechanical work or modifications are often required on-site to these pre-fabricated elements to enable mechanical, electrical, and plumbing (MEP) work and to customize them to the needs of the building design.

[0009] Furthermore, there are several issues associated with the construction of multi-story buildings using traditional construction techniques such as cast-in-place concrete frame buildings, precast concrete frame buildings, structural steel frame buildings, timber frame buildings, and masonry buildings. Multi-story buildings constructed with these construction techniques are built in the traditional way by on-site technicians who apply construction materials, first fabricating the framework of the multi-story dwelling on the foundation at the construction site according to a set of building plans. Although these construction methods have worked for many years, they have inherent inefficiencies that result in significant time, cost, and quality disadvantages.

[0010] Conventional construction techniques involve lengthy processes, resulting in prolonged construction activities. Furthermore, finishing work can only be achieved after the structural work is complete. The combination of these activities results in both financial burdens and enormous labor and man-hour costs. To improve time efficiency, this invention reduces the time required, including the time spent preparing prefabricated panels.

[0011] Manufacturing on-site can lead to a decline in quality, an increase in errors, particularly human errors, and requires workers to innovate regarding the interconnection of utilities, resulting in inconsistencies in implementation.

[0012] In summary, in all of the situations and scenarios described above, the construction process is time-consuming, requires a great deal of manpower, and is inefficient and costly. [Overview of the project]

[0013] The object of this application is to provide wall elements, unit construction systems and methods. Selected embodiments are included in the dependent claims. Each of them may represent an embodiment of this application, either alone or in any combination with other dependent claims. The subject matter described has been developed to enhance the techniques and methodologies used in the building construction industry for all kinds of building structures. Another object of this application is to construct any building that is environmentally friendly, stronger, faster and safer. A wall element in the sense of this application is an entire wall or a part of an entire wall as an element (e.g., in the case of a long and / or tall wall). A wall element in the sense of this application is in contrast to building boards (e.g., for drywalls) which can be, for example, part of a wall or even used to construct wall elements according to this application.

[0014] International Publication No. 2022074489 discloses modular panels and a system for using said panels.

[0015] This application provides a reduction in overall weight and thickness while achieving high flexibility, thermal insulation against widely changing temperatures and natural elements, and improved sound insulation.

[0016] According to one aspect of this application, a wall element comprises an inner surface, an outer surface, a stud, and at least one partial cavity and / or void. The stud is located between the inner surface and the outer surface. At least one partial cavity and / or void is also located between the inner surface and the outer surface. At least one partial cavity and / or void is designed to be filled with (reinforced) concrete. The cavity and / or partial cavity may extend from the top to the bottom of the wall element and / or from side to side. The cavity and / or partial cavity may not extend throughout the entire wall element. A cavity and / or partial cavity extending from the top to the bottom may merge with a cavity and / or partial cavity extending from side to side so as to form a curved cavity and / or partial cavity. The cavity and / or partial cavity to be filled with concrete is separated from areas or parts of the wall element that are not intended to be filled with concrete, such as voids. The wall element may additionally include such voids. In the context of this disclosure, partial cavities and voids are intended to be filled with (reinforced) concrete, while voids are not intended to be filled with concrete.

[0017] A wall element has a top and a bottom, and two sides extending between them. Each stud can be made from any suitable material such as concrete, wood, steel, stainless steel, aluminum, plastic, and combinations thereof. Studs included in a wall element may be made of different materials. The dimensions of the studs are arbitrary, as they directly affect the dimensions of the wall element (e.g., thickness or width). Each stud can be placed arbitrarily within a wall element and does not need to extend the entire length of the wall element. Studs can be placed within the wall element so as to extend (partially) from the top to the bottom of the wall element.

[0018] The inner and / or outer surfaces may include any suitable material such as board (e.g., gypsum, cement, cementitious fiber, OSB, MGO, natural slab, etc.), cement, plaster, stucco, natural stone, brick, block, PV panel, paint, etc.

[0019] Cavities and / or partial cavities can have any suitable dimensions. One dimension of a cavity can occupy the distance from the inner surface to the outer surface. In other words, a cavity can occupy the inner width of a wall element. Because the inner and / or outer surfaces have a certain thickness, cavities and / or partial cavities can have a width equal to the width of the wall element minus the respective thicknesses of the inner and outer surfaces. The same applies to gaps.

[0020] Where voids and / or partial voids extend from the top to the bottom of a wall element, they are designed so that, after being filled with concrete, the voids and / or partial voids form a column or partial column designed to withstand loads. Where voids and / or partial voids extend from side to side of a wall element, they are designed so that, after being filled with concrete, the voids and / or partial voids form a beam designed to withstand loads. The voids may be supported by temporary supports to withstand stresses during the pouring of concrete. For the scope and understanding of this application, the term “partial void” also refers to an initially partial void that is subsequently completed or sealed by, for example, another element.

[0021] This may have the advantage of allowing construction to be carried out in a time- and cost-efficient manner. Furthermore, construction can be carried out in a lightweight manner that is advantageous in terms of earthquake resilience.

[0022] According to one aspect of this application, at least one partial cavity or void of a wall element is at least partially composed of an inner surface and an outer surface, as well as at least one stud. This may have the advantage that the cavity and / or partial cavity can be created in a cost-effective manner. For example, the material used for the inner surface and / or outer surface is stable enough to act as a concrete formwork designed to fill the cavity or partial cavity.

[0023] According to one aspect of this application, a partial cavity in a wall element is located along the edge region of the wall element. The partial cavity is designed to be combined with a corresponding partial cavity in a wall element or to be sealed by a wall element installed later (such a sealed cavity is still referred to as a partial cavity in this application for distinction). In other words, a wall element is designed to be combined with another wall element such that at least one partial cavity becomes a (partial) cavity designed to be filled with concrete. If two wall elements both have partial cavities and are joined together at their respective edge regions, the two partial cavities form a single (partial) cavity that can be filled with concrete. If a first wall element having a partial cavity is joined with a second wall element that does not have a cavity that complements the partial cavity of the first wall element, the second wall element seals the partial cavity of the first wall element so that concrete can be poured into the created (partial) cavity. The edge region can be located on at least one or both sides, top or bottom of the wall element. This may have the advantage that a wall element, or multiple wall elements installed adjacent to each other, can function as formwork.

[0024] According to one aspect of this application, the wall element further comprises at least one of thermal insulation, fixing points for attachment, MEP equipment, and a sealing structure. The thermal insulation can improve the thermal insulation performance of the wall element. The fixing points for attachment may include fixing points for sinks or other heavy equipment, such as electrical cabinets or pumps, that are attached to the inner surface of the wall element. The fixing points may further include points for attachment to an outer surface, such as a protruding roof or billboard. The MEP equipment may include any known equipment in the art. This may have the advantage of allowing for the efficient construction of structures including a unit construction system. The sealing structure can seal an area where partial cavities of two wall elements are joined to form a single (partial) cavity.

[0025] According to one aspect of this application, the unit construction system comprises a first wall element and a second wall element as described above. The unit construction system further comprises a slab element. The first wall element and the second wall element support the slab element. The slab element may be any fully precast element (so-called "dry slab") or a partially precast element (for example, on which concrete is poured during the construction process). This may have the advantage of enabling the efficient construction of structures (for example, any building) that include multiple unit construction systems.

[0026] According to one aspect of this application, all elements of a unit construction system (e.g., wall and slab elements) are fluid-connected. Fluid connection allows, for example, concrete to flow between the slab elements and the first and / or second wall elements. This may have the advantage of allowing the structure to be built efficiently.

[0027] According to one aspect of the present application, the unit construction system further includes a third wall element installed following the first wall element or the second wall element. At least one partial cavity within the edge regions of the first wall element and / or the second wall element and the subsequently installed third wall element together form a (partial) cavity (see above). This means that the first wall element and / or the second wall element have at least one partial cavity in the edge region. The above partial cavity is complemented by another partial cavity included in the third element or by the third element itself (see above). The (partial) cavity / cavity is designed to be filled with (reinforced) concrete. This may have the advantage that the unit construction system can be used to construct a structure so as to enhance stability.

[0028] According to one aspect of the present application, the slab element of the unit construction system is positioned to be laid on top of the inner edge of the wall element(s). The inner edge can be positioned at the top of the wall element(s). The inner edge can be positioned in the vicinity of the inner surface. Also, the inner edge can be the top of the inner surface. This may have the advantage that a structure can be efficiently constructed using the unit construction system.

[0029] According to one aspect of the present application, the formwork of the slab element of the unit construction system is connected to the wall element. The formwork is used to pour the slab element in place. During pouring of the slab element, the concrete can also flow into at least one (partial) cavity formed by the wall element(s). This may have the advantage that a structure can be efficiently constructed using the unit construction system.

[0030] According to one aspect of the present application, the unit construction system includes a guide. The guide is designed to position the wall element during installation of the wall element. The guide can also assist in aligning the subsequently installed wall element. This may have the advantage that a structure can be efficiently constructed using the unit construction system.

[0031] According to one aspect of the present application, a method for installing a unit construction system, comprising: installing wall elements; positioning slab elements; pouring concrete such that the concrete fills (partial) cavities of the wall elements. This may have the advantage that a structure can be efficiently constructed using this method.

[0032] According to one aspect of the present application, the step of positioning slab elements includes positioning the slab elements in fluid communication with the wall elements. The step of positioning slab elements may also include pouring concrete into the slab elements such that the concrete fills (partial) cavities of the wall elements.

[0033] According to one aspect of the present application, the step of installing wall elements includes aligning partial cavities of respective wall elements to form (partial) cavities. This may be aligning two partial cavities each contained in respective wall elements that are aligned to form (partial) cavities together. Otherwise, only one of the wall elements contains a partial cavity, and the other wall element seals this partial cavity at the surface when, for example, the two wall elements are aligned, resulting in the formation of (partial) cavities. This may have the advantage that a structure can be efficiently constructed using this method.

[0034] According to one aspect of the present application, a reinforcing material is inserted into at least one (partial) cavity. The reinforcing material can connect the slab element to the wall element. The reinforcing material can be a reinforcing bar. This may have the advantage that the stability can be enhanced. The reinforcing material can be arranged on the slab element(s), for example bridging the slab element(s) (see below). For example, the reinforcing material contained in a precast slab (element) can be connected to the reinforcing material within at least one (partial) cavity.

[0035] According to one aspect of this application, the step of arranging the slab elements includes laying the slab elements on top of the inner edge of the wall element(s) (see above). This may have the advantage that the structure can be constructed efficiently using this method.

[0036] According to one aspect of this application, the step of arranging slab elements includes arranging formwork for slab elements that are connected to wall elements (see above). This may have the advantage that a structure can be constructed efficiently using this method.

[0037] According to one aspect of this application, the method further includes the step of positioning guides before the step of installing wall elements. Furthermore, the step of installing wall elements includes installing wall elements using guides. This may have the advantage that structures can be built efficiently using this method.

[0038] Each of the above embodiments should be considered an invention in itself. The embodiments may be freely combined with each other, and each feature not described as depending on another feature may also be freely combined with each other. Features of systems, elements, and methods may be interchangeable. Method steps are described at least in part with respect to each of the elements of this disclosure.

[0039] Further advantages and features of this disclosure will become apparent from the accompanying drawings. The drawings are for informational purposes only and not for limiting features. The drawings schematically illustrate embodiments of this application. Therefore, the accompanying drawings cannot be considered to limit, for example, the dimensions of this disclosure. [Brief explanation of the drawing]

[0040] [Figure 1] This is a schematic top (or bottom) cross-sectional plan view of a wall element. [Figure 2] This is another schematic side cross-section of the wall element shown in Figure 1. [Figure 3]This is a cross-sectional top view of the unit construction system (same as Figure 1). [Figure 4] This is a cross-sectional top view of the unit construction system (similar to Figure 3). [Figure 5] This is a schematic perspective of the unit construction system. [Figure 6] This is a flowchart showing the installation method for the unit construction system.

[0041] In different embodiments described herein, the same parts / elements are denoted by the same reference numerals; however, it should be noted that disclosures in the detailed description may apply to all parts / elements having the relevant reference numerals. Furthermore, directional terms / positions selected herein, such as left, right, top, bottom, upper, upper side, bottom, lower side, downward, lateral, and sideways, refer to the directly depicted figures and may apply to new positions after a change in position, or to other indicated positions in other figures. All figures are not to scale and should not be interpreted as representations of proportions. [Modes for carrying out the invention]

[0042] Referring first to Figure 1, a top (or bottom) cross-sectional plan view of the wall element 10 is shown. The cross-section is parallel to the top or bottom (or side to side) of the wall element 10. The wall element 10 comprises three studs 40 to which the inner surface 20 and outer surface 30 are attached. The studs 40 are positioned within the wall element 10 so as to extend from top to bottom, as can be seen in Figure 1. Between the outer studs 40 on each side of the wall element 10 is a third stud 40. The three studs 40, together with the inner surface 20 and outer surface 30, constitute two cavities 60 or voids 61. In the embodiment shown in Figure 1, the voids 61 are shown as not intended to be filled with concrete. There is an insulating material 80 positioned within the voids 61, positioned on the inner surface 20. However, the insulating material 80 may be (additionally) positioned on the outer surface 30 (see Figure 3), or may completely fill the voids / multiple voids 61. Each of the voids 61 may also be a cavity 60, and therefore may be designed and intended to be filled with concrete.

[0043] The outer studs 40 are offset toward the center of the wall element, or toward the stud 40 located in the center of the wall element 10. This offset creates a partial cavity 50 in each edge region 70 of the wall element 10. Only one such partial cavity 50 can exist within the wall element 10.

[0044] Figure 2 shows another cross-sectional view of the wall element 10 described above. The cross-section in Figure 2 is perpendicular to the projection plane of Figure 1. In other words, the cross-section in Figure 2 is perpendicular to the cross-section of Figure 1 and lies within one of the voids 61 shown in Figure 1. The wall element 10 is viewed from the side, and the studs 40 are visible. In Figure 2, a partial cavity 50 is shown at the top T of the wall element 10. There is an inner edge 95 of the wall element 10 (see below) to allow for the placement of the slab element 200. At the top T, the outer surface 30 extends further than the inner surface 20, however, this extension is optional. The inner surface 20 and the outer surface 30 can have the same height. When the slab element 200 or formwork for the slab element (not shown) is placed in contact with the inner edge 95, and concrete is subsequently poured into the slab element 200, the height of the outer surface 30 determines the thickness of the slab (element).

[0045] Although the inner surface 20 is shown to extend higher than the cavity bottom 51, the inner surface 20 may be coplanar with the cavity bottom 51. When concrete is poured into the partial cavity 50, especially when the wall element 10 is in contact with the slab element 200, the partial cavity 50 is filled with concrete, creating a beam that extends from side to side (from left to right in Figure 1).

[0046] Figure 2 further shows a guide 90 positioned at the bottom B of the wall element 10. The guide 90 can be fixed to the surface on which the wall element 10 is placed. Here, the guide 90 has the same width as the inner width of the wall element 10 so as to fit into the wall element 10. Because the wall element 10 fits precisely into the guide 10, it is easy to position the wall element(s) 10 when installing the guide. The guide 95 can be positioned only partially (for example, in areas where the wall elements 10 are placed adjacent to each other), or the guide 90 can extend along the entire length of the wall element (side to side, left to right in Figure 1), or it can be made even longer so that multiple wall elements 10 can be positioned on a single guide 90. There is an insulating material 80 positioned within the void 61 of the inner surface 20.

[0047] Figure 3 shows a cross-sectional top view (similar to Figure 1) of the unit construction system 100. The wall elements 11, 12, and 13 have essentially the same structure as those shown in Figure 1, but are for the insulation material 80 positioned on the outer surface 30. However, the second wall element 12 and the third wall element 13 have a longer outer surface 30 on one side over their respective partial cavities 50. Thus, by positioning the second wall element 12 and the third wall element 13 adjacent to each other, the (partial) cavity 50 is formed at the resulting corner (upper right corner in Figure 3). For ease of distinction and explanation, the first wall element 11 is shown to be at a slight distance from the second wall element 12. However, the wall elements 11 and 12 can be positioned so that their inner surface 20 and outer surface 30 are in contact with each other (at the aforementioned corner, etc.). The (partial) cavities resulting from the formation of two partial cavities 50 in the first wall element 11 and the second wall element 12 can be filled with concrete, such as the (partial) cavities 50 in the corners. The first wall element 11 and the third wall element 13 have partial cavities 50 at their other ends, shown at the respective corners (left and lower right) of the construction system 100, which may be complementary to other partial cavities of further wall elements. There are gaps 61 with insulating material 80 positioned between the partial cavities 50. Each of the gaps 61 may also be a cavity 60 and therefore may be designed and intended to be filled with concrete.

[0048] Figure 4 shows another cross-sectional top view (similar to Figure 3) of the unit construction system 100. Here, a first wall element 11 and a second wall element 12 are shown. The second wall element 12 has a partial cavity only on its right side. The two wall elements are shown spaced apart from each other, but can be placed touching each other (see above). The partial cavity 50 on the right side of the first wall element 11 is complemented by the surface (face) of the second wall element 12. Here, the surface includes an inner surface and an outer surface, as well as a stud 40. Thus, a cavity is formed that can be filled with concrete. Furthermore, such a gap may be closed by a sealing structure included in at least one of the wall elements to seal the partial cavity / void joined together by the two wall elements. Similarly, gaps 61 with insulating material 80 located between the partial cavities 50 exist. Each of the gaps 61 may be a cavity 60.

[0049] Figure 5 is a schematic perspective view of the unit construction system 100. The slab elements 200 are positioned to be laid on top of the inner edges 95 of each wall element 10 (see detail A). Reinforcement members 96 are placed within the void 50. Horizontal reinforcement members 97 are placed on the slab elements 200 to bridge, for example, the area where two slab elements 200 on the wall element 10 are joined (left side of Figure 5). The horizontal reinforcement members 97 can also reach the partial void 50.

[0050] As partially shown in Figure 5, concrete 201 is poured into the slab element 200. The concrete 201 builds up a layer on top of the slab element 200, filling the (partial) void 50. The upper part T of the wall element 10 has a vertical (partial) void 50 (see Figure 1) and a horizontal partial void 50 (see also Figure 2) with reinforcing members 96. These voids are also filled with concrete, thus forming columns (vertical) and beams (horizontal). The wall element 10 can be positioned and aligned by guides 90 (see Figure 2). Horizontal reinforcing members may also be present to reinforce the resulting beams. The (partial) void 50 can be supported by temporary supports to withstand the stresses during the pouring of concrete.

[0051] An alternative is to use dry slab elements that already have the desired thickness and therefore do not require concrete to be poured onto their tops. In such cases, concrete is poured only into the (partial) void 50 (vertically and / or horizontally). Such slab elements can be arranged as seen on the left side of Figure 5, where the slab elements meet at the top of the wall elements with a gap on the outer surface. Through this gap, concrete can be poured into the (partial) void 50. Alternatively, the slab elements may have openings into which concrete can be poured into the (partial) void 50.

[0052] Figure 6 is a flowchart of a method for installing the unit construction system 100 as described above. Essentially, all steps have already been described above. In the first step, the wall elements 10 are installed and their partial cavities 50 are aligned. Guides 90 may be placed before the step of installing the wall elements. Guides 90 can be used to position and align the wall elements in the step of installing the wall elements. In the subsequent step, the slab elements 200 are positioned. The slab elements 200 may be positioned to be in fluid communication with the wall elements 10 so that concrete poured onto the slab elements 200 can flow into the cavities. The slab elements 200 may be positioned to be laid on top of the inner edge 95 of the wall element(s).

[0053] In the next step, the reinforcing member 96 is inserted into at least one (partial) cavity 50 or cavity 60. The reinforcing member may also be in contact with the slab element. In the next step, concrete is poured into the slab element 200 so that the concrete fills the (partial) cavities 50 and / or cavities 60 of the wall element 10. The step of positioning the slab element may include positioning formwork for the slab element 200 connected to the wall element 10 in order to pour the slab element 200 in place.

[0054] In all figures, the same reference numerals are used for parts / elements that are the same or similar as those in other figures. Therefore, a detailed description of such parts / elements is given only once for brevity. Reference numerals such as 1st and 2nd are for distinguishing purposes only, as their order may be changed spontaneously. Dimensions, particularly those of partial cavities and voids, are illustrative. Both types of cavities (partial cavities 50 and voids 60) can be filled with concrete.

[0055] While the embodiments illustrate possible variations for carrying out the subject matter of this application, it should be noted that the subject matter of this application is not limited to the illustrated embodiments / variations, and numerous combinations of the embodiments / variations described herein are possible, and these combinations are in the realm of the skills of those skilled in the art, which are motivated by this description. The wall element 10 shown in Figures 1 to 5 has essentially the same basic design as that described with respect to Figure 1.

[0056] The scope of protection is determined by the attached claims. However, the specification and drawings should be considered when interpreting the claims. A single feature or combination of features described and / or illustrated may represent an independent inventive solution. The objectives of the independent solution can be found herein.

[0057] Furthermore, for better understanding, please note that the parts / elements are shown not at a constant scale, and / or are enlarged and / or reduced to some extent. [Explanation of symbols]
