FR2560625A2 - ORIENTABLE ANTISISMIC HOUSE WITH SIMPLIFIED RIGID FASTENERS FOR FRAME KNOTS AND TUBULAR SUPPORT LEGS - Google Patents

Abstract

Device for orientable anti-seismic house with rigid connections for nodes of a frame and tubular support legs. The invention relates to a device making it possible to assemble the nodes of a frame and the tubular support legs in a simple and rigid manner. The frame and the platform acting as a floor consist of horizontal beams 1 assembled to form an equilateral triangle. Three flying buttress beams 4 rise up towards the centre along the axis of the corners of this triangle. These beams rest against the connections of the horizontal ridge beams 7 assembled to form a Y. The peripheral beams 9 rise up from the corners of this base triangle towards the ends of the ridges. All the assemblies are carried out by means of bent flats 5-8-10-11-14 and of bolts with nuts and washers including on the support leg and keystone element. The device according to the invention is particularly intended for the erection of a house or buildings having several rooms.

Description

 The present invention relates to a house of the adjustable anti-seismic type with simplified rigid fasteners for structural nodes and tubular support legs.

 The present addition No. 2, to the patent application No. 83.

03800 filed on 4-3-83, improves the fixing of the support legs of this frame and simplifies the fixing of the peripheral beams on the support-tubular legs.

 Addition No. 1 to this patent application presented a fixing by cables or spiral ropes through the neutral fiber of these beams, which could lack rigidity for large frames subjected to heavy loads. There was no mention of the construction of the steerable platform linked to the tubular support legs.

 The device according to the invention overcomes these drawbacks.

 I1 in fact comprises three vertical tubes supporting three horizontal beams assembled in an equilateral triangle at the heart of these tubes. Three buttress beams rise from the angles of this triangle towards its center to support three horizontal ridge beams assembled in Y by folded flat bars and U-shaped bars perforated at the ends. The peripheral beams are then assembled by flat bars bent between the support tubes and the ends of the Li ridge. The assemblies and the volte key are made by means of bolts with nuts and washers. This constitutes the preferential realization.

 According to a variant, the vertical tubes can be replaced by folded flat bars with welded soleplate for fixing on the counter-sole support tubes which can receive a universal joint.

 Figure I shows the plan view (dilated) of this house frame.

 Figure 2 and 3 shows the view and in elevation and the side view of this frame.

 Figure 4 shows the plan view and the arrow view of the fixing of the beams on the vertical support tubes.

 Figure 5 shows the plan view and the arrow view of the same beams as above assembled by flat iron and sole on vertical support tube.

 Figure 6 shows the plan view and the arrow view of the ridge ends.

 Figure 7 shows the plan view and the view following arrow of the keystone.

 The device shown in Figure I has three t-beams or tubes 2 assembled in a horizontal equilateral triangle placed on three vertical beams. These tubes have been sawn and opened to receive the beams 1 on the cities and the three beams 4 forming an arc flying in the axis of the angles of this basic triangle. The upper part of these beams 4 abuts against the three flat irons 5 of assembly in (around the volte key) 6) of three horizontal ridge beams 7; these have perforated U-shaped flat irons at their ends 8.The peripheral beams 9 receive folded plates 10 or 11 at their ends allowing attachment to the tubular support legs 3 and to the flat irons 8 at the ends of the ridge 7 Intermediate beams 12 mounted parallel to the ridge are fixed between the buttress beams 4 and the peripheral beams 9. The tubular support legs can receive Cardan joints 73; they can also be replaced by flat bars with probed fixing base 14 for passage of a sling 15 or a bolt with ecrol and rendelles cut in an angle to catch up with the clamping list. When the basic triangle is achieved by means of tubes 2- with flat ends welded, we can pass through these tubes 2 e and on the outside of the studs 14 a sling cable t6 to balance the thrust of the flying buttresses 4. All of the flat iron assemblies on beams are made using bolts with nuts and washers as well as the keystone 6. The whole assembly rests on a circular, orientable platform 17.

 The device according to the invention is particularly intended for the construction of an earthquake-resistant house on retractable feet and on an adjustable platform, given its lightness if desired, it is also possible to make buildings with multiple hexagonal cells; the assembly of the frame can be done on the ground, which accelerates its construction, decreases its cost price. This one, practically completed, is then fixed on its feet.
