Load-bearing panel and construction system

Abstract

The invention relates to a load-bearing panel consisting of an expanded polystyrene (EPS) core, a metal frame that encases said EPS core, and two layers of mortar, one on each side of the load-bearing panel framework made up of said metal frame and said EPS core. The layers of mortar are made up of a mixture of solid aggregates selected from: Portland cement, micronised silica, polypropylene microfibre, cellulose powder and at least one rheological additive, in addition to liquid aggregates selected from: softened water and at least one resinous agent that induces the formation of microbubbles. Said load-bearing panel may be used to form wall panels, floor panels and ceiling panels. The invention further discloses a method for forming said load-bearing panel, and a construction system using an arrangement of load-bearing wall panels, load-bearing floor panels and load-bearing ceiling panels.

[0007] The words "prete riole wme" or "prefe entemente" mean that the declared option is taken as priority, but it is not the first option, so that another option could be used without it being considered that it affects the outcome of what is claimed.

[0008]

[0009] The terms wall and partition are considered equivalent and may be used interchangeably throughout the disclosure, so it should be considered that they affect the scope; Je Jo rcivintiteado.

[0010] EPS is the technical abbreviation that stands for expanded ptslrcretase.

[0011]

[0012] Said load-bearing panel i, comprises in its preferred embodiment a series of through openings Sa, and 5b, and a series of transverse through openings 5c and 5d, arranged to accommodate and allow the passage of pipes of various types, such as: electrical, communications, water supply and wastewater assessment.

[0013]

[0014] The arrangement shown in figures 1 A and 1 B gives an account of an alternative embodiment where the pferaisfed of cavities 7a,7 ÍJ.

[0015]

[0016] Essentially, the load-bearing panel 1 is composed of an EPS core 2, in which through openings 5a and 5b are optionally arranged, which coincide especially with the through openings 5a and 5b, arranged in a metallic frame 3, formed by two C-shaped metallic portions, 3a and 3b, and similarly, the EPS core 2 has transverse openings Se' and 5', which coincide especially with the openings 5e and 3d arranged in the load-bearing panel 1.

[0017]

[0018] In the same figure 3 A, already as an example of what corresponds to a certain C-shaped metallic portions: 3a and 3f>, the C-shaped metallic portion is observed, 3a comprises an interior foris'itisrlte! channel 10a. provided for i» inscrici st of the peripheral edges»; of the core of EÍ'S 2, where on each side of said interior plate ii, there remain I-shaped teígítudmaíes, I layi Ib.

[0019]

[0020] In, at the nte-ios, one of the corners of the fold made in the metal plate compendíente^ to form c ¡fíik's te'ra of the metal portions in the form of C: 3a or 3b. a cut is made that generates discontinuity in the corresponding lower section, generating a zone of adjustment 9a, which can fit with the corresponding notch 8a n 8b, of the EPS core.

[0021]

[0022] The diagram shown in Figure 3A illustrates what occurs in other areas of the load-bearing surface, being exemplary and

[0023]

[0024] Figures 6A, 6B, 6C, "A and 7g show configurations of load-bearing panels according to the present invention with provisions to allow the internal passage of service pipes: whether for electrical wiring, technical or potable water or wastewater.

[0025]

[0026]

[0027] Figure l O shows a preferred area and when required by structural seismic resistance, where the metal frame 3 can be reinforced with transverse elongated members 33a, 33b, 33c, and 33d.

[0028] Optionally, the metal frame 3 could be reinforced with elongated longitudinal members.

[0029]

[0030] When it is necessary to construct a multi-story building, the portable panel can be adapted, within the inventive concept of the present invention, to connect to at least one fwxi for «mirepistx»

[0033]

[0034] Similarly, a roof support beam Ttj is constructed, the cttssi can be appreciated from figures 13A, 1313, and 13C.

[0035] Figure 13 shows the formation of the frame 60, which comprises an EPS 92 core, two C-shaped ribbed portions: 92a, 91t>. which form a ribbed ribbed EPS 92 core, through openings 4, 96 at each diagonal end of each C-shaped ribbed portion, to coincide with a through opening of the EPS 92 core, a tube frame preferably of square cross-section with holes for joining the assembly, and transverse reinforcements 7a, 97b.

[0037] Figure 14 shows a main section of the building, constructed using a structural system consisting of a load-bearing wall 1, a load-bearing panel for the intermediate floor 39, a load-bearing panel for the intermediate floor 56, and a load-bearing panel for the enclosure "fo

[0038]

[0039] Figure 16 shows how the load-bearing panel I is retained in the load-bearing roof panel 79 in the construction system 96. It can be seen that the cavities 76a, 76b provided in the load-bearing roof panel 70 are joined with the corresponding cavities 77a, 77b in the panel. Each cavity has through holes so that, using joining means, preferably bolts and nuts, the corresponding joint can be made. Other cavities 78, 77c are shown for joining with other load-bearing panels, as well as through openings 8 in the load-bearing roof panel 70.

[0040] These through-holes, as well as the through-openings for the embodiments described above, can preferably be generated, although not necessarily by techniques such as drilling or punching.
