Abstract

To reduce the influence of the forces exerted on it by wind, a building (1) slopes in the direction of the wind and is tensioned in the opposite direction by means of cables (2).

Description

 Inclined house and elastic room elements

At the beginning high-rise buildings had Vierendel skeleton system, which had to take up the most of the wind-borne moments, later core in the middle, at the end "core" up to the outer wall (framework solution: John Honcock Center; Vierendel solution: World's

Trade center). Because of the 80 m house width below the John

2 Honcock C. solution could reach 145 kg / m of skeletal steel

2 chen in the case of 100 floors instead of 315kg / m, which can be found in the general 100-storey skyscrapers. Even greater steel reduction, or switching off the

Steel skeletons are a dream because you want because of the ever increasing property prices in valuable areas

"to go up", only the steel does not make this "to go up" profitable. Something like the extreme case

(john Honcock Center) therefore cannot be an example because in a building width of 80 m. lots of functional

Compulsory solutions had to be found.

The Cheops pyramid has no steel at all, the shape of J. Honcock C. is a bit like the shape of Cheops P., with relatively little steel. A shape approx between the two could give us the opportunity to build skyscrapers with as little steel as the amount of steel from very thin reinforced concrete walls of this theoretical house, only the interior rooms could not be used for anything sensible. However, if the fact that the construction is as sloping as a wall side of the written theoretical house - only checked from one side (for the time being we leave out the question of the other wind direction) - the wind could oppose it so that it tipped over into the larger one Angled side of the sloping direction could not yet pass, then because of the concentrated pressed cores this house would only have thin reinforced concrete walls, even over 100 floors. In this theory the hook lies on the other wind direction. To check the other direction we could ask the tensile forces of guy cables to help. Apparently a contradictory solution, namely these cables not only have to work against the headwind, but also against the horizontal forces of the building weight, which is caused by the said slope. It is true, but the amount of steel from such inclined high-rise buildings in the area of "double-just" cables is more than 100 times less than the amount of steel from conventional steel skeleton constructions, and even if we calculate the reduction factors of the steel cable with the extra price Relative amount of steel more ten times. Practically the amount of steel from the steel skeleton is missing. The core or the house can be built from reinforced concrete with a minimum amount of reinforcing steel by creeping formwork.

Further material reduction can be achieved with the plan inclined construction through joints on the points of the cable bracket. Namely, the different expansion of inclined cables, consequently the even greater horizontal movements, and their absorption by moments in the cores, would have caused the otherwise necessary amount of steel. The joints could also give the intermediate bevel core parts concentrated pressure.

In the following the invention will be explained by figures

Fig. 1 shows the theoretical design of the skyscraper in the case of steel skeleton switching;

2 shows the design necessary in the abstract way of thinking, provided that the wind has momentary action only from one side;

Fig. 3 shows the cable tension;

Fig. 4 shows the same variant as Fig. 3, only with a supplement that can be more suitable for small plots;

Fig. 5 shows Raumel ementrückhangung of sloping houses, which sloping houses are to be considered as sloping house cores; Fig. 6 shows the articulation of the main core of the house; Fig. 7 shows the statically determined, i.e. 3-point support of room elements;

8 shows the spatial framework design below the spatial element; Fig. 9 shows the panel design of? Spatial element;

Fig.lo shows a possibility of elastic connections of the panels;

Fig.ll shows an elastic fire retardant solution of the elastic panel connection by fire retardant material and mortar, where the panels are filled with fire retardant material.

The details of the figures are explained below:

1 core, or house :, 2 cable bracing; 3 substructure for the purpose of the smaller plot; 4 suspension of functional units or spatial elements; 5 joints in the sloping house; 6 three-point suspension or support; 7 space framework; 8 wall channels; 9 ceiling channels; lo hole for the Panäl connection; 11 panel connectors of smaller diameter than the hole (lo); 12 extension piece of panels; 13 fire-retardant mortars; 14 fire retardant fabrics.

Claims

1. Inclined high-rise building, characterized in that the building that extends upwards and to the side without being pressed, or without support that is connected to the ring effect of other houses, cores, is vertically different from the slope that is held by cable tensioning in the direction of the larger one Considering the angle of the slope of the house.
