STRUCTURAL SYSTEM WITH SELF-SCREENING, STRUCTURE THAT INCLUDES IT AND METHOD TO BUILD A STRUCTURE USING SAID STRUCTURAL SYSTEM WITH SELF-SCREENING

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of engineering, more specifically to the field of civil works and in particular provides a structural system with self-scaffolding, a structure that comprises it and a method for building a structure using said structural system with self-scaffolding.

BACKGROUND OF THE INVENTION

The growing demand for urban land has increased the number of tall buildings. There are three reasons why high-rise building is desirable. On the one hand, high-rise building implies greater efficiency in the use of urban land area, given that the usable area can be multiplied. On the other hand, there is a greater economic use of the urban land surface, which has a cost of up to 100 times higher than that of a rural or natural land. Third, there is a positive connotation associated with the image of the building.

High-rise building in wood, in addition to satisfying the previous objectives, has the advantage that its environmental impact is substantially less compared to other structural systems, since wood functions as a store of carbon captured from the atmosphere during the construction stage. tree growth. Furthermore, in the event of demolition, the building's structure is mostly biodegradable.

In general, in the state of the art, there are construction systems in wood for building in height. The two most common wood construction systems internationally are the structural partition system and the CLT (Cross Laminated Timber) construction system. However, these construction systems correspond to wall-type systems, which generates architectural distributions where the enclosures are segregated by the structural walls. This causes significant rigidity in the use of spaces and limits buildings to residential activities.

In the state of the art, construction systems in materials such as wood have been described. For example, CN 108505619 provides a prefabricated structural system and an assembly method thereof. Such a precast structural system can be used in steel structures, reinforced concrete structures and wooden structures. Said precast structural system includes a plurality of steel structural joints and related components, wherein said steel structural joints and said related components may further include a beam-column connection sleeve, a column, and a main beam. In addition, it may include a main beam fixed steel plate, wherein the beam-column connecting sleeve comprises a first box-shaped steel tube and a first C-shaped sleeve extending perpendicularly from an outer surface. of the first box-shaped steel tube, the first C-shaped sleeve is on the upper and lower flanges. The end part is provided with a first wedge-shaped recessed part, the column has a column connection end inserted into the first box-shaped steel tube; The main beam has a main beam connecting end inserted into the first C-shaped sleeve.

On the other hand, CN 108222289 describes an assembled bamboo wood beam-column joint structure, comprising a rectangular side column, a rectangular beam, a steel filler plate and a draw bolt. Such a steel filler plate is formed by welding an H-shaped steel plate and a tie plate. A bolt hole is arranged in the cross section of the net, and the end of the rectangular side column and the rectangular beam are provided with a notch and a hole for the bolt, where the size of the notch is the same as the part corresponding insertion of said tie plate, and the rectangular side column includes the upper lateral column and the lower lateral column. The upper side column, the lower side column and the rectangular beam are connected and fixed by the pull bolt and the steel filler plate. The connection mode of such bamboo wood structural steel filler plate has the characteristic of semi-rigid node, can better withstand the bending moment and shear force of the node and form a more stable mechanism system, and has a high node stiffness. The connection is reliable, the degree of industrialization is high, and the construction of the site is convenient.

However, the solutions known in the state of the art do not provide a self-scaffolding structural system for the construction of a structure, requiring additional elements for the building.

DETAILED DESCRIPTION OF THE INVENTION

In the following, the present invention will be described in detail with reference to the figures accompanying the present application.

As illustrated in Figs. 1 and 2, a first object of the present invention provides a type node that makes up the structural system with self-scaffolding (1) for the construction of a structure that essentially comprises: a pillar (2), said pillar (2) that has a square-shaped cross section, said pillar (2) having a first notch positioned at an intermediate portion of said pillar, said first notch having a first portion (21) on a front surface of said pillar (2) and a second portion (22), adjacent to said first portion (21) and positioned on a lateral surface of said pillar (2), said first portion (21) having a width and a height of length equal to a width of said front surface of said pillar (2) and a depth of length equal to half the width of said surface front of said pillar (2); and said second portion (22) having a width, a height and a depth of length equal to half the width of said front surface; a first beam (3) having a square shaped cross section equal to the cross section of said pillar (2), said first beam (3) having a cylindrical portion (31) in an intermediate position, said cylindrical portion (31 ) which is positioned eccentrically with respect to an axis of said first beam (3), said cylindrical portion (31) having a length equal to the width of said first portion (21) of said first notch and a diameter equal to the depth of said first portion (21) of said first notch; a second beam (4) said second beam (4) having a square-shaped cross section equal to the cross section of said pillar (2), said second beam (4) having a second notch positioned in an intermediate portion of said second beam (4), said second notch having a third portion (41) positioned on a front surface of said second beam (4) and a fourth portion (42), adjacent to said third portion (41) and positioned on a surface side of said second beam (4), said third portion (41) and fourth portion (41) having the same shape and dimensions as said first portion (21) and said second portion (22) of said first notch, respectively; a plurality of fittings (5a, 5b, 5c, 5d), each of said fittings (5) said plurality of fittings (5 ^§ , 5b, 5c, 5d) presenting a first face (51), a second face (52 ) arranged perpendicular to said first face, and a rib (53) connecting said first face (51) and said second face (52); wherein said first face (51) and said second face (52) have a first plurality of through holes (54a, 54b, 54c, 54d) having a first diameter; and a plurality of bolts (6 ^§ , 6b, 6c, 6d), each of said bolts of said plurality of bolts (6 ^§ , 6b, 6c, 6d) having an outer diameter corresponding to said first diameter of said first plurality of through perforations (54a, 54b, 54c, 54d) and a length equal to or greater than the length of said width of said lateral surface of said pillar (2); wherein said pillar (2), said first beam (3) and said second beam (4) are connected perpendicular to each other; wherein each of said fittings (5) of said plurality of fittings (5a, 5b, 5c, 5d) connects a surface of said pillar (2) with a surface of said first beam (3) or with a surface of said second beam (4); and wherein each of said bolts of said plurality of bolts (6a, 6b, 6c, 6d) connects two fittings of said plurality of fittings (5a, 5b, 5c, 5d) opposed to each other.

In the context of the present invention, the term self-scaffolding structural system is to be understood as a set of structural elements that fulfill both the function of a structure and a scaffold. Advantageously, without limiting the scope of the present invention, it can be understood that the structural system with self-scaffolding (1) that is the object of the present invention constitutes a lost scaffold constructive system, therefore, as the construction of the work advances, the parts of said structural system with self-scaffolding and its type node (1) that functioned as a scaffold now function as a supporting structure. This allows the structure to be assembled without having external auxiliary structural elements, such as scaffolding or risers, thus speeding up the assembly time.

On the other hand, in the context of the present invention, a plurality should be understood to refer to two or more of the mentioned element. In this sense, for example and without limiting the scope of the present invention, when referring to a plurality of fittings (5a, 5b, 5c, 5d), it must broadly understood to refer to two or more fittings.

Additionally, spatial references, such as up, down, forward, backward, upper, lower, among others, should be understood as referring to the structural system with self-scaffolding (1) when it is normally in use, but they do not limit the scope of the present invention and are only provided for a better understanding thereof. In this sense, without limiting the scope of the present invention, it will be understood that when the typical node of the self-scaffolding structural system (1) is normally in use, the pillar (2) extends in a vertical direction, the first beam (3) extends in a lateral direction and the second beam (4) extends in an anterior-posterior direction, as illustrated in the figures accompanying the present application.

As previously mentioned, said type node of the structural system with self-scaffolding (1) comprises a column (2), a first beam (3) and a second beam (4), as well as a plurality of fittings (5a, 5b, 5c, 5d) and a plurality of bolts (6a, 6b, 6c, 6d) that join said pillar (2) to said first beam (3) or to said second beam (4).

With respect to said pillar (2), as seen schematically in Figure 5, it has a square-shaped cross section. Said pillar (2), additionally, has a first notch positioned in an intermediate portion of said pillar (2). Said notch has a first portion (21) on a front surface of said pillar (2) and a second portion (22), adjacent to said first portion (21) and positioned on a lateral surface of said pillar (2), said first portion (21) having a width and a height of length equal to a width of said front surface of said pillar (2) and a depth of length equal to half the width of said front surface of said pillar (2); and said second portion (22) having a width, a height and a depth of length equal to half the width of said front surface.

On the other hand, the lateral dimensions, as well as the length of said pillar (2) do not limit the scope of the present invention. Said pillar (2) can be formed by a single piece or by a plurality of segments (23, 24), as illustrated schematically in Figures 17 and 18, without limiting the scope of the present invention. In the case of being formed by a plurality of segments (23, 24), the way in which said plurality of segments are joined does not limit the scope of the present invention. Additionally, the number and length of each of said segments that are part of the plurality of sections (23, 24) does not limit the scope of the present invention. Said segments that are part of the plurality of segments (23, 24) may or may not have the same length without limiting the scope of the present invention.

In a preferred embodiment, without limiting the scope of the present invention, two consecutive segments can be joined by means of a piece (8) comprising a plurality of parallel plates connected to each other and inserted into said consecutive segments. Each of said plates has a plurality of through holes of a second diameter. Additionally, said consecutive segments are joined by means of a plurality of complementary bolts (9a, 9b) and nuts (10a, 10b), said plurality of bolts (9a, 9b) passing through said consecutive segments and said plurality of parallel plates. In this way, advantageously and without limiting the scope of the present invention, said plurality of segments (23, 24) can be joined without affecting the mechanical properties of said pillar (2).

Regardless of whether said pillar (2) is formed by a single piece or by a plurality of segments (23, 24), said pillar (2) can present a plurality of first notches, without this limiting the scope of the present invention. For example, and without limiting the scope of the present invention, when said pillar (2) comprises a plurality of segments (23, 24), each of said segments may have a corresponding first notch which, in turn, has a corresponding first portion (21a, 21b) and a corresponding second portion (22a, 22b), wherein each of said corresponding first portion (21a, 21b) and corresponding second portion (22a, 22b) has an identical shape and dimensions to the first portion (21) and the second portion (22) previously described, respectively. On the other hand, and without limiting the scope of the present invention, when said pillar (2) is formed by a single piece, said single piece can have a plurality of first notches, where each of said first notches of said plurality has a corresponding first portion (21a, 21b) and a corresponding second portion (22a, 22b), said corresponding first portion (21a, 21b) and corresponding second portion (22a, 22b) having a shape and dimensions identical to said first portion (21) and second portion (22), respectively. In the case where said pillar (2) has a plurality of first notches, the spacing between said first notches does not limit the scope of the present invention. For example, and without limiting the scope of the present invention, said plurality of first notches may or may not be uniformly distributed along said pillar (2).

With respect to said first beam (3), as seen schematically in Figure 5, it has a square-shaped cross section equal to the cross section of said pillar (2). Said first beam (3) additionally has a cylindrical portion (31) in an intermediate position. Said cylindrical portion (31) is positioned eccentrically with respect to an axis of said first beam (3) and has a length equal to the width of said first portion (21) of said first notch and a diameter equal to the depth of said first notch (21).

On the other hand, the lateral dimensions, as well as the length of said first beam (3) do not limit the scope of the present invention. Said first beam (3) can be formed by a single piece or by a plurality of segments (32, 33), as illustrated schematically in Figure 19, without limiting the scope of the present invention. In the case of being formed by a plurality of segments (32, 33), the way in which said plurality of segments are joined does not limit the scope of the present invention. Additionally, the number and length of each of said segments that are part of the plurality of segments (32, 33) does not limit the scope of the present invention. Said segments that are part of the plurality of segments (32, 33) may or may not have the same length without limiting the scope of the present invention.

In a preferred embodiment, without limiting the scope of the present invention, two consecutive segments can be joined by means of a piece (8) comprising a plurality of parallel plates connected to each other and which are inserted into those consecutive segments. Each of said plates has a plurality of through holes of a second diameter. Additionally, said consecutive segments are joined by means of a plurality of complementary bolts (9a, 9b) and nuts (10a, 10b), said plurality of bolts (9a, 9b) passing through said consecutive segments and said plurality of parallel plates. In this way, advantageously and without limiting the scope of the present invention, said plurality of segments (32, 33) can be joined without affecting the mechanical properties of said first beam (3).

Regardless of whether said first beam (3) is formed by a single piece or by a plurality of interconnected segments (32, 33), said first beam (3) can present a plurality of cylindrical portions (31) without this limiting the scope of the present invention. For example, and without limiting the scope of the present invention, when said first beam (3) comprises a plurality of interconnected pieces (32, 33), each of said pieces can present a corresponding cylindrical portion in an intermediate position. In this case, furthermore, said corresponding cylindrical portion is positioned eccentrically with respect to the axis of said section. Each corresponding cylindrical portion, moreover, can have a shape and dimensions identical to the previously described cylindrical portion (31), namely, a length equal to the width of the first section (21) of the notch of the pillar (2) and a diameter equal to the depth of said first section (21). On the other hand, and without limiting the scope of the present invention, when said first beam (3) is formed by a single piece, said single piece can have a plurality of cylindrical portions, where each of said cylindrical portions of said plurality has a length equal to the width of the first portion (21) of the notch in the pillar (2) and a diameter equal to the depth of said first portion (21). In the case where said first beam (3) has a plurality of cylindrical portions, the spacing between said cylindrical portions does not limit the scope of the present invention. For example, and without limiting the scope of the present invention, said plurality of cylindrical portions may or may not be uniformly distributed along said first beam (3). With respect to said second beam (4), as seen schematically in Figure 5, it has a square-shaped cross section equal to the cross section of the pillar (2). Said second beam (4) additionally has a second notch positioned in an intermediate portion of said second beam (4). Said second notch has a third portion (41) on a front surface of said second beam (4) and a fourth portion (42), adjacent to said third portion (41) and positioned on a lateral surface of said second beam (4) , said third portion (41) and fourth portion (42) having the same shape and dimensions as the first portion (21) and second portion (22) of the first notch of the pillar (2), respectively. That is, said third portion (41) has a width and a height of length equal to a width of the front surface of said pillar (2) and a depth of length equal to half the width of said front surface of said pillar ( 2); and said fourth portion (42) has a width, a height and a depth of length equal to half the width of said front surface of said pillar (2).

On the other hand, the lateral dimensions, as well as the length of said second beam (4) do not limit the scope of the present invention. Said second beam (4) can be formed by a single piece or by a plurality of segments, which are not illustrated in the figures, without this limiting the scope of the present invention. In the case of being formed by a plurality of segments, the way in which said plurality of segments are joined does not limit the scope of the present invention. Additionally, the number and length of each of said segments that are part of the plurality of segments do not limit the scope of the present invention. Said segments that are part of the plurality of segments may or may not have the same length without limiting the scope of the present invention.
