The present invention is in the fields of concrete structures construction. More specifically, the invention relates to a modular structural system and construction method thereof, which is utilized for efficient construction of various structures in an economical modular manner.
Current construction methods aim to industrialize the construction process, using frames, advanced techniques and materials for constructing large structures.
However, none of these methods has yet solved crucial problems of the construction industry, such as structure failure, disengagement of reinforcement frames from molded structural elements, disintegration and cracking, and loss of workers lives during the construction process.
Many of the above failures and risks are due to the numerous manual tasks being performed in inconvenient postures at heights (e.g., pre-casting preparations for concrete structures including molds and reinforcement mesh installation, and post-casting tasks such as uninstalling molds).
The costs of construction are currently also still high because of the heavy workload and equipment, which are required and the significant amount of time for completing a construction from the foundation to the finish.
It is therefore an object of the present invention, to provide a modular structural system of pre-made elements and coupling means that structurally integrate with the casted concrete structure thereby do not require post-casting disassembly and reducing the pre-casting preparations.
It is another object of the present invention, to provide a modular structural system and construction method thereof, which enables simple and modular construction of extended structural elements, thereby enabling reduced construction time.
Other objects and advantages of the invention will become apparent as the description proceeds.
The invention relates to a modular structural system, comprising: a) one or more building units being comprised of two counter mold partitions, each of which is adapted with one or more anchoring means, into which one or more connecting locks (i.e., which may be of an adjustable length) are engaged to firmly lock and stabilize the two counter mold partitions, wherein each of the two counter mold partitions is peripherally adapted to receive one or more affixing coupling means, b) two or more coupling means for affixing two of the one or more building units, and c) two or more coupling means for affixing the one or more building units to an adjacent building element.
The two or more mold partitions are selected from the group consisting of: a solid plate, a multilayered plate (e.g., comprising a thermal isolation layer), or any combination thereof.
According to one embodiment of the present invention, the one or more anchoring means are added onto the two or more mold partitions. According to another embodiment of the invention the one or more anchoring means are integrated within the two or more mold partitions.
According to an embodiment of the present invention, the one or more anchoring means is integrated with the two or more coupling means.
The invention further relates to a modular construction method, comprising: a) providing one or more building units being comprised of two counter mold partitions, being connected by connecting locks, b) affixing each two residing building units by two or more coupling means, c) affixing building units to an adjacent building element, by two or more coupling means, and d) casting a solidifying substance into the one or more building units.
According to an embodiment of the present invention, the utility elements are embedded within one or more of the two counter mold partitions before casting a solidifying substance into the one or more building units.
According to an embodiment of the present invention, one or more adjustable connecting locks are provided to enable modifying the depth of the one or more building units before casting the solidifying substance into the one or more building units.
The solidifying substance may be prepared from a mixture of at least two of the following materials:
White cement;
Black cement;
Sea sand;
Quartz sand;
Fiberglass fibres;
Fiberglass rods construction;
Power and fibres of basalt;
Mineral wool;
Sodium-Chloride power.
The present invention relates to a modular structural system, comprising multilayered building units of multiple different types, being engaged to form building elements (e.g., construction wall, gravity wall, piling wall, cantilever wall, anchored wall, staircase, internal walls, etc.) in a fast and modular manner, where each building unit is constructed of two counter partitions being firmly connected by suitable connecting locks, thus forming a mold into which solidifying substance such as concrete is casted. The proposed system further comprises suitable coupling means as well as adhesive materials for affixing two residing building units, or for affixing building units to adjacent building element such as to the floor.
In the following detailed description, references are made to the accompanying drawings that form a part hereof, and in which are shown by way of illustrating specific embodiments or examples. These embodiments may be combined, other embodiments may be utilized, and other changes may be made without departing from the spirit or scope of the present invention.
Furthermore, mold partitions 101 and 102 comprises longitudinal grooves 101b and 102b correspondingly, into which coupling means such as rectangular profiles 110 are engaged for coupling residing building units (e.g., mold partitions 101 of building units 100a and 100b), or such as floor affixing unit 120 being anchored to the floor for affixing building unit 100b to a floor surface 130. The width and depth of profiles 110 are selected to be reduced with respect to grooves 101b and 102b, to allow application of suitable portion of adhesive and sealing materials. Of course, multiple different designs of profiles 110 may be selected by one skilled in the art according to specific desirable designs of building units 100a and 100b as well as its fitness to desirable internal elements (e.g., where a horizontal building unit is utilized for constructing a ceiling with downwardly protruding anchors for lighting fixtures).
While mold partitions 101 and 102 of
The proposed structure system enables a highly efficient construction method, according to which an extended mold (i.e., which is stabilized and affixed to adjacent structure elements) is assembled, into which concrete (i.e., or other suitable solidifying material) is casted to form a complete structure element, which does not require pre assembly of wooden/metal mold plates and steel reinforcements, and does not require post-casting disassembly of the mold plates (i.e., mold partitions 101 and 102 are an integral element of building units 101a 101b), thereby enabling a relatively fast construction of structure elements.
Upon casting concrete into the mold formed between the two counter mold partitions, static pressure is applied to both partitions due to the weight of the casted concrete. The higher the partitions are, the higher is the pressure. This pressure between counter mold partitions applies opposing lateral forces on the partitions which causes the anchoring means to strongly pull the connecting locks to two opposing directions. These lateral forces has two positive effects. First, the structure is maximally stabilized since the locks are tensioned. Second, the casted concrete is solidified on tensioned metals (in this case, the locks) and thereby causes a similar reinforcement effect to the effect of Prestressed concrete. This strongly increases the of the resulting walls durability against socks, such as during earthquakes.
Moreover, utilizing the proposed system and method can reduce (i.e., and possibly eliminate in some cases) the need for scaffoldings, thus requiring fewer scaffoldings at the construction site, hence further reducing construction costs and duration.
According to one embodiment of the present invention, the solidifying substance is prepared from a mixture of at least two of the following materials:
White cement;
Black cement;
Sea sand;
Quartz sand;
Fiberglass fibres;
Fiberglass rods construction;
Power and fibres of basalt;
Mineral wool;
Sodium-Chloride power.
Although embodiments of the invention have been described by way of illustration, it will be understood that the invention may be carried out with many variations, modifications, and adaptations, without exceeding the scope of the claims.
