Definitions

  • the present invention relates to a technique for constructing prefabricated post and beam type buildings, whether of wood, reinforced concrete or any other material.
  • Reinforced concrete buildings of the post-beam type are rather rare, because it is more advantageous to make horizontal and vertical linkages, in one piece for each floor, as much as possible: reinforcement and concrete pouring.
  • posts and beams are widely used. They are always prefabricated and brought to construction sites to be assembled using various points and / or fittings.
  • the document FR 941.058 discloses a construction technique of the post and prefabricated beam type according to the preamble of claim 1.
  • the present invention relates to a construction technique of wood, reinforced concrete or any other material, which consists in using posts and beams prefabricated in the factory, and in making their connection on the construction site, on the one hand by a system of vertical and horizontal bracing, and on the other hand by a reinforced concrete junction at their intersection.
  • braces which securely hold the posts and beams in their final position as soon as their installation is completed. They make a connection that we describe here as peripheral, as opposed to the central connection made at the intersection of said posts and beams.
  • Threaded rods are the most suitable means of joining braces to posts and beams.
  • the central junction can itself be cast on site; we then speak of partial prefabrication, or prefabricated, and we then speak of total prefabrication.
  • the contact surface between a brace and a post or beam can be simple, without any special arrangement. In this case, if there is a force which tends to open or close the angle formed by the column and the beam, the bracing will play its role by opposing it. But so that the bracing does not slide along the post or the beam, the connecting rod will be stressed in shear and must therefore be of large section. To remedy this problem, roughness is provided on said surfaces, a notch in the post or beam, a notch in which a wedge fits at the end of the bracing, etc. Such a system prevents any risk of the bracing slipping against the post or against the beam in the event of a force tending to modify the angle formed by the post and the beam.
  • the external notch prevents the closing of said angle, and the internal notch prevents its opening.
  • the internal notch is longer than the external notch, and can even form an acute angle with the axis of the post or beam.
  • a joint is applied at their intersection. form of cement mortar for example.
  • bracing pieces There is no limit in the number or inclination of the bracing pieces, nor in the number or type of their attachment to posts or beams: bolts, dowels, rivets, nails, etc. The same applies to the connection between the terminal blocks and the ends of the posts and beams described below.
  • Partial prefabrication pouring the junction on site
  • the beams are prefabricated in the factory, with bars or waiting bars which will enter the junctions.
  • an area of around 20 cm is provided at the base which will be concreted on site at the time of their installation, with waiting bars.
  • waiting bars are provided at the top of the posts to form part of the junction, and to serve as waiting bars for the subsequent assembly of the post of the upper floor.
  • the reinforcement of the junction is prefabricated, either fully or partially. It can take the form of a metal frame, preferably welded.
  • the posts and beams whose reinforcement entering the junction is prefabricated are provided with small pieces of waiting iron on which will be welded the prefabricated reinforcement of the junction.
  • a complete terminal block with as many branches as there are posts and beams in this node will be connected to the ends of the posts and beams which enter the node.
  • the area of assembly of a branch of the block with a post or a beam can be cut along an oblique line, i.e. bevel, along a straight line, along a broken line, ie staircase, etc. .
  • terminal blocks as well as the ends of the posts and beams which form the junction, are manufactured in such a way as to provide them with high mechanical resistance: dense reinforcement and maximum dosage of concrete.
  • the contact surfaces have deep grooves or other forms of roughness, intended to prevent the relative movement of the elements to be connected.
  • Threaded rods are the most suitable means of joining posts and beams to terminal blocks.
  • the ends of the posts and beams which enter this node then take the form of a T to correspond to the dimensions of the terminal block thus formed.
  • the thickness of the different parts of the terminal block must take into account the thickness of the ends of the posts and beams to which it will be linked, so that the total thickness does not differ too much from the thickness of the posts and beams, for example 20 cm.
  • the central part of the terminal block which is not attached to any end of post or beam keeps the thickness of the posts and beams, 20 cm in our example.
  • the areas of the terminal block to which are attached only one end of a post or beam have a thickness of the order of 10 cm in our example, half the thickness of the structure of the construction. The same is true, mutatis mutandis, of the areas of the terminal block which are crossed by two ends.
  • the thickness of one end of a post or beam must in turn take account of the thickness of the other ends and of the branch of the terminal block with which they will be in contact in the knot, to make a total thickness of 20 cm in our example.
  • the assembly of posts and beams is usually done using various fittings.
  • the junction is made of reinforced concrete. It is then a question of securely fixing steel bars to the ends of the posts and beams, so that they have waiting bars which will participate in the production of said junction.
  • the present invention also takes advantage of cross nailing for good fixing of wooden braces, on posts and beams also in wood.
  • the zones which are liable to crack or burst due to intensive nailing are surrounded by compression fittings, which at the same time increases the pressure exerted on the nails used and therefore improves the connection produced.
  • the primary object of the invention is the most extensive prefabrication possible of the structure of buildings of the column and beam type, prefabrication which allows industrialization of this type of construction.
  • the main development which makes it possible to achieve this objective under the same technical conditions, or even better than in the conventional system, is the massive use of bracing in both the vertical and horizontal directions. They constitute a peripheral and solid junction which connects the posts and the beams on the one hand and the beams between them on the other hand.
  • the central junction which takes place at the intersection of posts and beams, can be carried out on site or prefabricated, and therefore industrialized, or at least highly standardized.
  • this modular lattice structure is lighter than a conventional structure.
  • the main constraint of the system is that the braces occupy the axis of the walls for more efficiency, which prevents or reduces the use of usual materials in the construction of walls such as bricks and blocks of all kinds. But this will push manufacturers to adopt more often the walls and walls suitable for this type of structure, for example the panels currently used in wooden construction.
  • Such a construction system is of special interest for regions with high seismic risk, since the building is light, consisting of a set of structurally self-sufficient units, highly triangulated and therefore very little deformable, all this at a relatively modest cost. .
