The LAPIS shelter project in Vitosha Park is not a project for a single building in several variants but is a demonstration of the possibilities of combining the elements we designed to achieve design goals.


LIGHT, ECONOMIC OPTION. WITHOUT VENTILATED PLASTER AND THERMAL BRIDGE.

The design of the modular panel for walls, roofs and floors (2,42x4,84m) is dimensioned for a ribbed (triple) thermo pane made of two layers of hot galvanized cold-bent steel sheet 0,5 mm thick and an insulating layer of polyurethane foam or Stone wool with a total thickness of 78 mm (along with the rib). The ribs are calculated to absorb the loads on the short side of the panel - 2.42 m and additional steel beams inside the panel assembly, every one meter away. The modular panel is embossed with a steel profile (hot dip galvanized cold-bent and dust-injected PVC paint), which together with the thermo pane sheet and the adjoining profile when touched by the modular panels at an angle of 60 to 90 degrees form a beam.


The ventilated modular panel (2, 42x4, 84m) for roofs, walls and floors is constructed on the same principle as the cheap, but three-layer thermo pane is without ribbing and is placed on the inside. From the outside, a spacer known as the "cassette" is added by means of a spacer (30 to 80 mm) acting as a rib (intermediate beam). The cartridge we chose is 255mm x 38mm and is also made of hot galvanized cold Bent steel sheet with powder-coated PVC paint The added ventilating layer is structurally interrupted and the thermal bridge in the modular panel.

PRICE-LISTED OPTIONAL PRICE AND ADDITIONAL INSULATION OF 160mm
- Rib (height) - 38 mm - 30, 50 BGN / m2
- Ventilation layer - 40mm - 24, 00 лв / м2
- Inner layer of thermo-panel - 40mm - 36, 00 лв / м2
- Additional layer - 160mm - 70, 00 лв / м2

The price is without profit for manufacturers. The price is without transport and installation of the site.

Centers include the production of custom-made items, cutting, drilling, riveting, riveting, screwing, etc. to a ready-to-transport element-modular panel for walls, roofs and floors. This is the average price per 1 m2 of construction surface. It also includes all functional supplements in the part of constructional - openable and non-opening doors.

For the project, due to the high altitude, we also offer the floor construction of the main level to be assembled. For evaluation, we introduce an index of structural surfaces. This is the ratio of all enclosing structural surfaces (together with the floor area) to the floor area and the intermediate level. In comparison to a parallelepiped with a base area of 18 m2 and a structural height of 2.42 meters, this coefficient is 4.29. For model # 1 of our shelter project, the factor is 3.30. For model # 2 of our shelter project, the factor is 3.63. For Model # 3 (cube) of our shelter project, the factor is 3.60. For the variant 1 offered by our project, the estimated price for execution is 3, 30 x 70,50lv / m2 and 3, 30 x 160, 50 BGN / m2 of total built-up area. ADDITIONAL HEAT INSULATION

On the inside of the volume module, we add a three-layer thermo pan with a thickness of 40 to 300 mm (with a structural profile for modular installation) to achieve the required thermal insulation. We have a technological and technical solution to modulate the modular panels to be packaged and transported by road container without carrying and container. Load securing during transportation and unloading will be accomplished with temporarily strengthened corners that are comparable to those of the containers.

1. Effective Materials "Lapis" is an architectural and design project for static dimensioning and constructive implementation of static and dynamic materials (steel, aluminium, wood, composites, plastic, textile membranes, sculptures, vinyl and a combination of them) Of a shaping spatial structural skeleton on which to construct facilities and buildings of different functional use to the degree of completion according to the requirements of the particular project.

2. The structural skeleton is dimensioned as a bulk cell in which space stiffness adds facade, roof and floor elements mounted on the shaping profiles. The main beam beams are located in the plane of the roof structure, thus enabling the removal of large facade panels by grouping the modules into larger structures.

3. Complementing the structural skeleton can be refined internally (reinforced) with existing external enclosures. With this, the building can change its purpose and its surface by being additionally loaded with installations, walls, insulations, and new floor constructions.

4. Connections are dimensioned for aluminium and steel plates, rivets and bolts. Technologically, the problem of dust and sound insulation from impact noise has been solved.

5. Changing the facade trays can be replaced after installation and the purpose of an already assembled volume module changes. Thus, in the place of the dismantled bulkhead (s), there may be bulkheads out of the volume of the module with functional uses for the entrance antechamber, a bathroom, a staircase, a clothes cabinet, a cabinet for installing air conditioners, a coffee machine, an ATM, Refrigerated showcase and other facilities.

6. The foundation is made of monolithic and mounting steps or winding dowels, without massive reinforced concrete elements in the ground.

7. The provision of earthquake is embedded in the architectural volumetric form, which is obtained from triangular structural frames, resistant to horizontal loads - wind and earthquake.

8. The waterproofing is solved with an architectural design system, with a high degree of security, including against reinforcement. These are the highly inclined roofs and wall skates with a built-in water drainage system.

The water removal is decided on four sides in the flat and on the two sides at the sloping roofs. The profile contains in its geometry water-bump (edge sheet) and gutter (drainage gutter). The ribbing of the panels on the short side of the roof slope serves for water-guiding grooves and snow-holding edges at the same time.

9. Thermal insulation. The facades are designed to be executed by elements of systems for hinged (structural) facades, producers of aluminium profiles and structures. We have developed hot-dip galvanized cold-bent and PVC-coated steel sheet. The façade systems can be supplemented by the 40 mm, 80 mm, 120 mm, 320 mm post-assembly method to achieve the required computational parameters, including reaching a "passive" building with wall thicknesses up to 800 mm.

10. Materials - A wide range of semi-finished products for the construction and automotive industries can be used for the additional insulation installed inside the module (transport and installation size), depending on the degree of thermal insulation required and the investor's demand for the quality of the interior materials.

11. The non-open windows are made of two and three-layer glass pane, glued to aluminium or steel glass holders (profile - opening for opening elements) and mounted on the facade structure hangers as well as façade panels.

12. Openable windows are mounted on the hangers (ribs) of the inner edge of the facade panel. The choice of a system of openable windows is optional by the investor. Entrance and interior doors are mounted on hangers.

13. Upper lighting can be integrated into the roof and wall heat sink panels and also be made of polycarbonate panels with the same profile.

14. Fire protection. The structural shaping frames can be displayed over the roof and outside the facade. Fireproofing panels are thermo-resistant to the roof and wall coverings.

15. Alternative

17. Production The components are manufactured with a high degree of completeness - ready for operation and habitation, in factory conditions, guaranteed geometry parameters, static stability and service life.

18. Economical With the architectural volume shaped by us, a reduced ratio of the roof, wall and floor surfaces to the base (PU and POM) is achieved. The result is a reduction in the amount of fencing materials and, for the rest, a decrease in the calculated load of snow and wind (with a gradient of 45 degrees - by 41%). Breaking the parallelepiped shape with sloping roof and wall surfaces is an approximation to the perfect static form for buildings - the hemisphere.

19. Different. The combination of efficient materials with construction technology for production and installation and a design system for modular dimensioning of the construction together with a volume-architectural solution makes the volumes always different.

20. Equally Modular modular panels can be assembled into different shape, size and floor modules. With the same modules, different structures can be built. A combination of different modules can be built on different structures.

21. Factory Manufactures of beams, city walls, trays, linear and angular joints from the manufacturing semi-finished products of the construction and automotive industry. From the modular trays, objects of different sizes and shapes are assembled.

22. Sale and transport Purchase of materials. All this is done with mass produced for the retail stores of materials, semi-manufactured and other products up to 6 meters in size does not require specialized transport. The size of the modular element is chosen because of the dimensions of the authorized freight transport (without falling into the oversized load category) and the internal dimensions of a 12-foot container.

23. Masking on the ribs, edges and folds of roof and wall trays can be mounted with a screwdriver on all available mudguards without disturbing the hood and thermal insulation without disturbing the built-in water removal system. The addition adds a second ventilation layer to the system.

24. Living standard. Ventilated facade, roof and floor. The lightweight, economical façade structure of the LAPIS system contains a ventilated layer and a broken thermal bridge.
