BUILDING SYSTEM
The invention relates to the building system, including rods with screws, sliding from its butt-ends, and balls with radial directed screw-seats.
The nearest prototype of the invention is the building system "Mero" that was patented by German inventor Mr. Menheringhausen and demonstrated at first in 1957 on Exhibition "Interbau", Berlin.
The "Mero" system, included the rods with screws, sliding from the rod's butt-ends, and the balls with radial screw-seats, is used for assembly of space frames which square cells are usually filled ith square panels, having the side, equal [approximately] to the length of the rod.
In the frames of formal critic, which is needed for explaining of the invention and only in that sense, we may assert, that the building system, including said rods, said balls and the square panels with the side, equal to the rod length, such system has the disadvantage in that the known panels make linear joins in one flatness only. The space frame has the square cells, placed in different [mutually perpendicular] flatnesses, but the sides of that cells are inclined to each other at angle 60°, how shall be inclined also the sides of the panels which may fill that cells [see Picture 4 and commentary to it].
The aim of the invention is to create a building system which includes unified light-weight rods and panels and is capable to make transformable walls and ceilings with linear joins in all three mutually perpendicular flatnesses.
That is achieved by including to the system a square panel with diagonal axis, equal to the double length of the rod plus diametrical size of the ball. The panel has the screws, sliding from corners of the panel along its diagonal axes.
The indicated position of the screws and relations between the sizes of the panel, the rod and the ball ensure, that one panel may be putted to the space frame changing by itself four cross-placed rods, jointed by one central ball.
According to geometry of the space frame, proposed panel can make linear joins with the same panels, installed in the all three mutually perpendicular flatnesses.
The invention has many different ways for realization, now will be described the best [in author's opinion] from its.
The proposed panel has edges, sloped at angle 45° to flatness of the diagonal axes of the panel.
The sloped edges of neighboring panels may be hermeticated by scotch tapes [crossed over the balls] and covered by planks and pyramidal presses level with surface of the panel.
Every ball has 18 radial screw- seats. 12 - big for rod's and panel's screws and 6 small seats for small press's screws, directed to space diagonals of the octahedron.
The screws of the rod and of the panel are unified and may be tightened by means of the same instrument which has a set up for axis fixation of the screw and a set up for its turning.
The instrument may be used by one hand and by touch.
In "Mero" system's space's frame the screw of the rod is passed through a support tube, which is installed between the ball and a body of the rod, and transmits a tectonic strain of pressing.
The known support tube has stabile length and it is a reason of difficulties with putting to assembly place [between the balls] every next rod after the third and with a disassembly of the rods from a middle part of the space frame.
The elements of proposed building system [the rod and a panel] are equipped by a unified support tube, having a zone with an elastic curved wall, which in moment of tightening of the screw is capable to be straightened and to move the support tube forward from the body of the element on quantity of the assembly clearance.
As a result are obtained easy assembling and disassembling of the elements and possibility of space transformations according to change of need.
The elements of the system have sockets for immediate access to heads of the unified screws.
The rod of the system has three T-form ribs, placed radial at angle 120° and assembly sockets between the ribs on the ends of the rod.
The assembly socket of the panel made in form of hollows in panels corners, closed by lids level with the surface of the panel.
The panel carries the tectonic strain which concentrates in the panel's corners.
For strengthening of the corners the panel is provided with internal support ribs, and the sockets are placed between the corners ribs.
Inside of the panel made a vacuum with a gas pressure so low, that transmission of sound and warm by convection through the gas practically is absent.
For contraction to external atmospheric pressure between the shells of the panel is installed a prop, having a plate with double-side ribs, winded around by a silicate thread between the ribs.
The thread damps a sound vibration.
Transmission of the warm [by contact] along a thread is very low.
Internal surfaces of the panel are metallised for reducing of the warm transmission by radiation.
The abodes are separated by [as minimum] two layers of the panels.
The elements may be used repeatedly, the sole expense material is the scotch, used for hermetication of the panel's joins - the several grams on square meter.
Light weight and unification of the elements make conditions for maximal concentration and automation of production and, taking into account also easy assembling of the system, - for extremely radical reducing of building cost.
The essence of the invention is explained by 23 Pictures with the next numeral designations :
Commentaries for the Pictures:
P. 1 - [Picture 1] is a fragment of a building that is assembled from the elements of the system.
A local section shows that the wall and the ceiling have identical construction, which includes the rods 1 , the balls 2 and the panels 3, placed in the all three mutually perpendicular flatnesses.
The joins between the panels are coveiied by the external planks 4 and the presses 5.
The external elements [3,4,5] may be produced by pressing from a metallurgical slag-glass [now that material as an industrial waste has zero or negative cost].
After crystallization it obtains high firmness and fire- resistance.
Frosted, white or light-gray surfaces of walls, floors and ceilings are not needed in any obligatory finishing.
The space 6 inside of the frame may be used for installing of the pipelines, cables, ventilation, heating and other equipment.
Taking into account the light-weight [about 105 kg/m and extraordinary rigidity of the construction [the hinges are absent] we may come to conclusion about very high seismic-resistance of the system and its ability to insure the transformations of the building volumes inside and outside, including increasing of the abodes at the expense of an external space.
P.2 - is a fragment of the floor.
The joins of the panels 3 are open [the exclusion is a local section A, which presents external plank 5 and internal plank 8]. The section A shows that between the panels 3 the rod is absent.
P.3 - is an axonometrical view of an assembly block from the elements of the system, explaining its mutually arrangement and relations between its size, described in the first [general] Claim of the invention.
The planks 5 and 8 are removed.
A local section B shows the screw 9 which joints a left-hand panel 3 and the ball 2.
The axis of the screw 9 coincides with the diagonal axis 10 of the panel
3, so may be said :"the panel has screws s l i d i n g from panels corners along its diagonal axes".
A dotted line on surface of a right-hand panel 3 shows silhouettes of four cross-placed rods 1 [jointed by the ball 2] which was changed by the panel 3. The diagonal axis of the panel 10, coincides with the axes of two rods 1.
The letters on the Picture 3 sign :
R -the length of the rod 1, b - the diametrical size of the ball 2,
D - the size of the diagonal axis of the panel.
So, the expression D = 2R + b may be read like :
"The diagonal axis of the panel is equal to double length of the rod plus diametric size of the ball".
[ Sizes of the elements was dimensioned after the tightening of the screws 9.]
Beside of the left-hand panel are delineated the silhouettes of two panels 3, installed in flatnesses, placed mutually perpendicular to each other and to the left-hand panel.
The screws 9 of that panels have axes coinciding with diagonal axes
10 of the panels and ax.es of the rods 1, which may be changed by that panels.
P.4 - is a model, explaining the geometry of the space frame. In the same scale and position like on axonometry P.3 is delineated an assembly block from the balls 2 and the rods 1, having axes 11, which product a regular polyhedron -the octahedron which has twenty equal ribs, making eight equilateral triangles.
Space orientation of six balls 2, jointing the rods 1, and of central ball 2 is identical.
The axes of twenty big screw- seats 13 are continued by twenty octahedron's ribs 11, so we can say, that the ball 2 of the system has big screw-seats 13, directed according to ribs 11 of the octahedron. Three mutually perpendicular space diagonals 12 of the octahedron are coincides with axes of small screw-seats of the ball 2, delineated on its crossing, so we can say, that the ball of the system has six small screw- seats 14, directed according to space diagonals of the octahedron. [ "Mero" system's ball also has eighteen screw-seats, but those all have the same diameter.]
On the model we can see three square cells produced by the rods 1 and placed in three mutually perpendicular flatnesses The panels, that may fill the cells placed in crossing flatnesses can not make the linear joins, because its sides are inclined to each other at angle 60° .
P.5 - is an encased geometrical scheme of the joining element of the system, conventionally called " the ball " 2, presented like a polyhedron.
P.6 - is a ball 2 with real external surface 15, including spherical fragments.
P.7 - is a section, which shows that the big screw seats 13 for turning of unified screws are made like a through holes, but the small screw- seats 14 for press-screws are blind.
On Pictures 5, 6, and 7 is delineated the quantity "b" - diametrical size of the ball 2 as a length of the axis, united two opposite screw-seats 13. Inside of the ball 2 is made a cavity 16, reducing the ball 2 weight.
P. 8 - is a view of the panel 3 with edges 7, sloped at angle 45 to flatness of the diagonal axes 10, a head 19 of the screw 9, installed in a panel assembly socket 18 with possibility of sliding along the diagonal axis 10 [turned to the ball 2] and the lids 17, closing the other three sockets.
P. 9 - is a side view of the panel 3.
P.10 - an opposite side of the panel 3 with fragment of smooth surface and open internal surface, having support ribs 21 , strengthening the panels corners, back surfaces of the assembly sockets 18, placed between the ribs 21 , and open joint 22 united the shells of the panel 3.
For the better isolation qualities of the panel 3 in a hermetic cavity 23 is made a vacuum with gas pressure so low that transmission of sound and warm by convection through the gas practically is absent.
For reducing of warm transmission by radiation an internal surface of the cavity has reflected covering.
For contraction to external atmospheric pressure between the shells is installed a prop 24.
P.11 - is an increased view of the prop 24.
P.12 - is a section of the prop 24 which shows the panel's 3 shells 21 , one-side ribbed plates 25, and double-ribbed plate 26, winded around by a silicate thread 28 across to direction of the ribs 27.
By means of the plates 25 a pressing of the shells 21 is putted to the thread 28 between the ribs 27 of the double-ribbed plate 26.
The thread, made, for example, of quartz is very thin, that is why a warm-transmission by contact along the thread is infinitesimal.
A sound vibration is damped by tighten thread 28 twice, that is more effective.
P.13 - is a view of an instrument 41 for assembly of the systems elements. The instrument 41 has a butt-end key 34, turned by conic gears 35, 37 , installed on a bent at angle shaft 36 ; a set up for turning, having a crown 38, a lean 39, a lever 40 for changing of turning direction ; and a set up for axis fixation of the unified screw 9, having a hook 43, a bush 44 and a teeth 45.
P.14 - is a section though the assembly socket 18 of the panel 3 with the instrument inside it.
P.15 - is a panel's corner sectioned in flatness of the diagonals axes . •
We see the screw 9 and a support tube 20 with zone of elastic curved wall 46 represented in two positions. Up from diagonal axis 10 we see the elastic curved wall in free state. Dawn - represented the state after
the tightening of the screw 9. The elastic wall 46 pressed between a conic bush 29 of the panel and conic surface of the screw 9, was straightened, became longer and moved the end of the support tube 20 forward from the body of the panel on quantity of an assembly clearance M.
P.16 - is a section of elastic curved wall 46 explaining that a pressing in direction CE moves the support tube 20 in direction CD because the way in direction CO is closed by a support ring 30.
For the better elasticity the wall 46 has radial slots31.
(A deformations are represented in a certain conventional increasing.)
P.17 - is a side view of the rod's 1 end.
P.18 - is a section across the assembly socket of the rod 1 with the instrument inside of the socket.
P.19 - is a section across a rod's body.
P.20 - is an axis section of the rod 1.
The rod's 1 body made of hot-impressed steel or of cast in a cockle aluminum and has three T-form radial ribs 47, 48 placed at angle 120° and butt-end ring 49 inside of which are installed the unified screw 9 with the head 19, a support ring 30, the unified support tube 20 having a zone of elastic curved wall 46, and a conic bush 51.
The assembly socket 50 of the rod 1 ensures three-side access to the head 19 of the screw 9.
The deformations of the elastic wall 46 of the unified support tube 20 are described in the commentary to Picture 15.
P.21 - is a view from abode to an assembly block. We see four panels 3 jointed by means of ball 2. One of the panel's sockets 18 is open and we see the screw 9. Two planks 4 are removed, one is sectioned and we see its vacuum cavity 59.
The press 5 represented fragmentally.
The sloped edges 7 of the panels are hermeticated by the scotch tapes 52, which crossed over the ball 2.
P.22 - is a side view to the assembly block. In section we see a contact between a sloped butt-end 54 of the external plank 4 and pyramidal surface 55 of the press 5, which is jointed to the ball 2 by small screw 56 closed by lid 57. Internal plank 8 has a hollow 58 in form of the rod 1. The assembly sockets 50 of the rods 1 are open, that ensure an immediate access to the heads 19 of the screws 9.
P.23 - is a view to the assembly block from side of the space frame. We see the internal plank 8 with the vacuum cavity 59 and the hollow 58, also the internal press 53 with the lid 57 of the small screw.
