Definitions

  • This invention relates to a boxing for concrete buildings as well as to a method for using such a boxing.
  • An object of the present invention is thus to offset the drawbacks of the constructional methods heretofore conventional, by drastically reducing the times which are required for erecting building for civil dwelling and removing to a degree the specialized workmanship for the different operations, while still ensuring a considerable accuracy in processing, also in sequentially ordered steps and without originating problems as to shipping and manipulation.
  • this invention suggests, in the first place, a newly conceived boxing, by employing which it becomes possible to adopt a novel erection procedure which affords a number of advantages both as regards the rapidity of performance of the works and the accuracy of the erection steps with a reduced workmanship and without specialized people.
  • the boxing according to the invention is essentially characterized in that it comprises a supporting structure or framing for conventional boxing-closure panels, composed of assemblable and interchangeable members of stamped, bent and perforarated sheet metal, said sheet metal members being intended to provide a vertical and horizontal structural skeleton to which are removably affixable the boxing-closure panels.
  • the fundamental component part of said supporting structure is a member which can serve both as an upright and as a beam and is substantially composed of two L-shaped rolled sections confrontingly spaced apart from one another with their longer webs which are connected together at regular intervals by couples of small tubes, whereas the shorter webs of the two rolled sections lie on the same plane and are equipped with bores for securing the boxing-closure panels resting against the outer surfaces of said shorter webs.
  • an element is provided, to be called a base board, said element being similar to the upright/ beam element aforementioned, but is shorter than the latter and has a baseplate for resting on said reference plane.
  • the supporting structure of the boxing then comprises a few auxiliary elements, such as foraminous junction plates, joint coverings, takeup Z-shaped plates, angular plates, tie bars of adjustable length and others, as will be better understood from the ensuing detailed description aided by the accompanying drawings.
  • boxing provided according to the present invention it is possible to carry out an erection method for houses for civil dwelling which is clearly distinguished over those of the prior and contemporary art and this both in comparison with the conventional processes using boxings assembled at the building yards and those which use prefabricated elements.
  • the erection method according to the present invention provides in the first place the laying and assembling of the supporting structure composed of uprights and beams following a preselected pattern and providing also the openings for doors and windows, whereafter there are positioned within the hollow spaces of the walls, possibly after having applied the panels of either surface thereof, the installations for any kind of services, the iron reinforcing bars and others, whereafter the boxing closure us proceeded with by applying the panels to the other surface of the walls and lastly carrying out the casting of the concrete mix by pouring it down initially in the outer and inner walls and then in the floors and cantilevers, if any, whereupon the entire surface exposed is smoothly plastered.
  • FIGURE 1 On a horizontal foundation plane or an already cast floor, the trend of the inner and the outer walls of a set of rooms to be erected is patterned, on taking into account the thicknesses of the walls one desires to erect and of the wood panels of the boxing and indicating the positions and the dimensions of the doors, windows, servicing appliances, installations and the like.
  • the drawing clearly shows by small squares the positions of the uprights for the walls and by dotted lines the positions of the floor beams forming the supporting structure for the boxing as provided according to the invention.
  • FIGURE 1 there are clearly indicated such small squares 10, the dotted lines 11 for the floor beams and the thickness 12 of the wood panels for the boxing. In addition, there are shown windows 13 and doors 14.
  • the baseboard 15 is composed of two L-shaped rolled sections, 16 and 17, respectively, which are integral at either end with a baseplate 18.
  • the two rolled irons 16 and 17 are confrontingly mounted and spaced apart from one another with their longer webs 16a and 17a (see FIGURES 3 and 4) which are mutually interconnected by a couple of small tubes 19, whereas their shorter webs 16b and 17b lies on the same plane and carry bores 21 for fastening the boxing-closure panels 20.
  • the baseplate 18 has bores 22 for securing the baseboard 15 on the horizontal plane (see FIGURES 2 and 6).
  • the upright components 24, the first of which is secured to the couple of plates 23, have a standard length.
  • three upright elements 24 plus a baseboard 15 and a couple of plates 23 for adjustment it is possible to attain the desired height, as shown in FIGURE 2.
  • the upright elements 24 have the same configuration as the baseboard elements 15, the only difference being that the former are longer than the latter and are not fitted with the baseplate 18. Conversely, the elements 24 are equipped with a plurality of couples of small tubes 19 for connecting the longer webs of the rolled sections in the shape of an L, said couples of small tubes being marshalled along the length of said roller sections.
  • an adjustable tensioning device 27 can be inserted as shown in FIGURES 2 and 6, which also acts as a shore.
  • the assembling of the upright elements 24 which serve to attain the desired wall height that is of those elements 24 which follow the first one which has been secured to the baseboard 15 via the couple of adjusting plates 23, can be carried out on a plane, then completing the last element 24 with appropriate terminal headers which are require for the several subsequent operations. All the assembly of these elements united together can thus be lifted and connected to the first upright element which has already been erected and vertically plumbed.
  • An upright intended for coacting with a floor beam is completed with terminal headers consisting of takeup Z-shaped plates, indicated at 28 in FIGURE 5, an upright placed on the outer periphery being intended to limit the floor thickness is completed at its top by two adjusting plates 23 and an upright which is intended to have united thereto a short cantilever beam can be terminated by joint coverings such as 25 and so forth.
  • FIGURE 7 The wall corners, both internal and external, are made with two uprights, as shown in FIGURE 7, which are connected together by special angle plates 29 and 30, right and left, respectively, one of which is shown in another view also in FIGURE 8 and in the development on a plane in FIGURE 9.
  • Each of these angle plates comprises a first bedplate 31 having two bores for connecting, by bolting, to a couple of small tubes 19 which connect the longer webs 16a and 17a of an upright element 24. From the bedplate 31 is bent at right angles a wall 32 which is terminated by an oblique edge, from which is bent at right angles a second bedplate 33 oriented along a direction opposite to that of the first bedplate 31.
  • this second bedplate 33 has two bores. From the wall 32 there are then bent towards the first bedplate 31 two reinforcing webs 34, 35 which are made integral with the bedplate 31 itself.
  • the right and the left angle plates are distinguished from one another exclusively in that the bedplates 31 and 33 are bent relative to the wall 32 in opposite directions, on taking into account that the webs 34, 35 are always bent towards the first bedplate 31.
  • couples of right and left angle plates 29, 30 which are connected together in correspondence with their second bedplates 33, the latter being positioned the one along-side the other by bolting or otherwise, as can be clearly seen in FIGURE 7.
  • the uprights of the supporting structure which relate to the same building wall are positioned pairwise symmetrically and frontally so as to be able to provide conveniently, through the slits between the two L-shaped rolled sections forming the uprights, for the positioning of tie bars and spreaders to ensure the tightness of the boxing.
  • Such an horizontal structure is made up with the same elements which have already been exploited for the vertical structure. It comprises beam elements and bracket elements for overhangingly supporting balconi-s, eaves and like members.
  • the upright elements 24, already disclosed in the foregoing, are used once again, but now they act as beams and the adjusting plates 23 are likewise used.
  • FIG. 5 To the upper couple of small tubes 19 of the last upright element 24 at top there are bolted two Z-plates 28. Each web of each Z-plate has four bores with a couple of bores oriented vertically and the second couple oriented horizontally. To these two Z-plates there can be secured two adjustment plates 23 so as to attain the desired beam span, and to the plates 23 there are secured again two additional Z-plates. Between the free webs of the latter the first element 24 is now secured, which has now the function of a beam, that is, with its two larger webs arranged vertically and with its shorter webs arranged horizontally and directed upwardly. The junction between subsequent elements 24 is still made by joint coverings 25. As outlined above all the component parts which are necessary to make up an entire beam can be assembled and completed still on the ground in readiness for being fastened to the Z-plates 28 carried atop the upright elements 24.
  • FIGURE 6 shows by way of example how there can be positioned within a wall a water-distribution unit 36 intended to connect the pipelines of a bathroom and/or a kitchen to vertical pipelines 37 embedded within the wall thickness, whereas in the thickness of the floor horizontal pipes 38 are embedded. It is apparent that the operations of laying, jointing and others for all of these services can easily be carried out with the boxing still open, whereas the fittings intended to protrude out of the wall surfaces shall be shielded in any appropriate way.
  • the Z-plates 28 and the foraminous plates 23 for adjustment as shown in FIGURE 2.
  • the counterframes of the doors and the counterframes of the windows can be placed in position by exploiting appropriate means to have these component parts embedded in the cast concrete.
  • the empty spaces to be allowed for the headrooms to be left for sliding shutter compartments and the like are obtained by inserting appropriate shims, for example ones of expanded plastics materials, to be removed upon casting the concrete mix and to be thrown away subsequently.
  • the boxing is readiness for effecting the concrete mixture casting thereinto, to be carried out by pouring is continuously in the form of a sticky and soft putty and starting from the outer and the inner walls and ending with the floors and the overhanging portions of the building. Once the desired thickness for the floors is achieved, the entire exposed surface is plastered and smoothed.
  • FIGURES 10 and 11 show this possibility and are illustrative also of a modification of the formation of the corners of the walls.
  • FIGURES of drawings show the wooden slabs 40 to be recovered, which are secured to the uprights of the supporting structure and it is likewise possible to see the non-reusable panels 41 which are temporarily secured to the wooden slabs 40 and which close the boxing.
  • the modification relative to the formation of the corners consists in employing, in the stead of the special angle plates 29, 30 shown in FIGURES 8 and 9, simple angled rolled sections 43 arranged as can clearly be seen in FIGURES 10 and 11 to latch the wooden slabs 40 in correspondence with the corners.
  • the wooden slabs 40 are caused alternatingly to project beyond the edges of the corners and a stable union is thus obtained which well withstands the thrust originated by the concrete casting.
