• the present invention relates to a construction technique of wood, reinforced concrete or any other material, which consists of using prefabricated columns and beams in the factory, and to carry out their connection on 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.
• a central role is played by the bracings that securely hold the posts and beams in their final position as soon as their installation is complete. They make a link that we call here device, as opposed to the central link made at the intersection of said posts and beams.
• Threaded rods are the most appropriate means of joining braces to studs and beams.
• the central junction can itself be cast on site; we are talking about partial or prefabricated prefabrication, and we are talking about total prefabrication.
• the contact surface between a brace and a post or beam can be simple without any particular provision.
• the bracing will play its role in opposing it.
• the assembly rod will be stressed in shear and should therefore be of large section.
• it is expected roughness on said surfaces a notch in the post or beam, a notch into which enters a shim provided at the end of the brace, etc..
• the outer notch prevents closure of said angle
• the inner notch prevents its opening.
• the inner notch is longer than the outer notch, and may even form an acute angle with the axis of the pole or beam.
• bracing pieces There is no limitation in the number or inclination of bracing pieces, nor in the number or type of their attachment to posts or beams: bolts, dowels, rivets, nails, etc. It is the same for the connection between the terminal blocks and the ends of the columns and beams described below.
• the beams are prefabricated at the factory, with bars or irons waiting to enter the junctions.
• Posts and beams are securely held in their final position by horizontal and vertical bracing.
• the ends of said posts and beams form a formwork lost at the time of pouring concrete in the junction.
• the reinforcement of the junction is prefabricated, either completely or partially. It can take the form of a metal frame, preferably welded.

• the assembly area of a branch of the block with a post or a beam can be cut along an oblique line, ie bevelled, along a straight line, along a broken line, that is to say a staircase, etc. .
• junction blocks as well as the ends of the posts and beams that form the junction are manufactured to ensure high mechanical strength: dense reinforcement and maximum concrete dosage.
• the contact surfaces have deep grooves or other forms of asperities intended to prevent the relative movement of the elements to be connected.
• Threaded rods are the means of assembling poles and beams to the most suitable terminal blocks.
• the ends of the columns and beams that enter this node then take the form of a T to match 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 columns and beams to which it will be connected, so that the total thickness does not differ too much from the thickness of the columns and beams, for example. example 20 cm.
• the central portion of the terminal block which is not contiguous to any post or beam end, retains the thickness of the posts and beams, 20 cm in our example.
• the areas of the terminal block to which are joined a single end of post or beam have a thickness of about 10 cm in our example, half the thickness of the structure of the construction. It is the same, mutatis mutandis, 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 into account the thickness of the other ends and the branch of the terminal block with which they are going to be in contact. the knot, to make a total thickness of 20 cm in our example.
• the assembly of posts and beams is usually done using various hardware. But in the context of the present invention, the junction is reinforced concrete. It is then a question of securely fixing the steel bars at the ends of the posts and the beams, so that they present waiting irons which will participate in the realization of said junction.
• the present invention also takes advantage of cross-nailing for good attachment of wood bracing, poles and beams also wood.
• the areas that are likely to crack or burst as a result of intensive nailing are surrounded by compression fittings, which at the same time increases the pressure exerted on the nails used and improves the connection achieved.

• Figure 4/20 shows a pole whose junction with the lower chaining is already concreted: the connection is complete.
• Figure 5/20 shows the installation of the beams that will form the upper chaining of the stage.
• a beam (8) is distinguished, as well as the reinforcement of the junction (9) constituted by the waiting bars of the left beam, those of the right beam and those of the upper end of the pole.
• Figure 6/20 shows the same elements as the previous figure, but after concreting the junction: the completion of the junction is complete.
• Figure 7/20 shows a sectional view of all the links in a node of the construction, highlighting the concreted parts on site.
• Figure 8/20 shows a prefabricated terminal block for the connection of the various posts and beams that enter the node, in case of total prefabrication.
• Figure 9/20 shows a terminal block that is already attached to the pole. There is an assembly rod (1 1), and two beams (1 2) pending fixation on the block.

• Figure 12/20 shows the diagram of an assembly of a beam with bracing. No special provision has been made for the contact area. In case of force tending to open or close the angle formed by the post and the beam, the bracing will oppose it. The connecting rod will be stressed in shear and must be dimensioned.
• FIG. 13/20 shows the diagram of the same beam-bracing assembly in which a notch in which a wedge fits in the beam is provided. provided on the bracing, to prevent sliding of the brace against the beam, and shear forces that would result for the connecting rod.

• the formwork is then made where it is necessary, that is to say in the nodes which comprise two or three beams, keeping in mind that the ends of the columns and beams constitute a lost formwork, then the concrete is poured. in the junction.
• step 3 ° is repeated for the continuation of the construction of the next stage.
• the primary object of the invention is as much prefabrication as possible of the structure of buildings of the type of columns and beams, prefabrication which allows industrialization of this type of construction.
• the main development that achieves this goal under the same technical conditions, or better than in the conventional system, is the massive use of bracing both vertically and horizontally. 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 done 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 greater efficiency, which prevents or reduces the use of the 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 adapted to this type of structure, for example the panels currently used in the construction of wood.
• Such a construction system is of special interest for regions with high seismic risk, because the building is light, consisting of a set of structurally self-sufficient units, strongly triangulated and therefore very little deformable, all at a relatively modest cost .
