Definitions

  • the present invention is an improvement over the prior art devices since it provides for the utilization of prefabricated support beams which are mounted and embedded permanently in concrete support members at opposed sides of the excavated site. This permits the immediate replacement of the road surface with a minimum loss of time and interruption of the traffic flow. r 1 g
  • the above task is accomplished, according. to the present invention, by providing for a prefabricated'support base which can be permanentlyinstalled-and avoids the necessity of temporary steel plates or other temporary structures during the complete excavation beneath the surface of the ground.
  • the invention additionally includes ancillary Supporting and reinforcing concepts which provide for the'necessary strength to permit normal traffic to pass over a road surface laid upon the support which excavation continues below ground level.
  • a further object of this invention is to provide addition rein- When the work is to be begun, two guide ditches, approximately 2 meters in depth, are dug into the solid ground 1 extending from the level of the street 6, along each of the opposed longitudinal sides of the site to be excavated, without interrupting normal street use by vehicular traffic. Each ditch is lined or filled with a wall 2, as shown in FIG. 2, leaving an open space between each pair of walls 2. In FIG. 1 only one guide wall 2 is shown; however, in FIG. 1 the tunneling has been substantially completed and the-inner one of the guide walls 2 along each longitudinal side of the excavation has been removed since the supporting structure has been completed.
  • FIG. 1 is a front elevation partially insection showing the support structure of the present invention.
  • FIG. 3 is a perspective view partially in section of the support element shown in FIGS. 1 and 2.
  • the prefabricated support members 4 (FIG. 4) are embedded upon the crown 3 of the still fresh cement side walls 3 being held for setting purposes by the guides 2.
  • the prefabricated members 4 include a plurality of downwardly projecting reinforcing iron rods 47, which during pre'fabrication are fixedly mounted (FIG. 2) to the block 4 by the upper extremities 50 of stem 51.
  • the downwardly projecting extremity 52 is U-shaped and dur ing assembly the U-shaped projection is inserted into the freshly poured concrete so as to be immovable when the concrete is hardened.
  • the U shaped members are arranged in opposite pairs and arranged so that the extremities 52 of the U-shaped portions are closer to each other than the stem portions 51. It has been found this enhances the strength of the structure; the extremity of one of said rods inserted into arm 4a and the rod of each pair inserted into arm 4b. 1
  • the support member is basically L- shaped and the upstanding arm 4a of the member 4 is serrated by a plurality of vertically extending slots 45forming vertical legs 42, the upper face 4d of which is at ground level.
  • the horizontally extending arm 4b has a series of grooves 43 in the horizontal face 41 which are freely communicable with the vertical slots at the point the vertical arm joins the horizontal arm and also as seen in FIG. 2 open to the crown 3 of the side wall 3.
  • concrete enters into the grooves 43 from the crown 3 which is still soft, and additional concrete is poured into'the grooves 43 to make a firm bond between the support member 4 and the crown 3' of the concrete wall 3.
  • the flat portion 5a is in the uppermost position and the narrower stem 5b shaped, arranged in opposed pairs, in which the U-shaped extremity 61 are curved towards each other and closer together than stems 64.
  • Rods 60 are located in alignment with and inserted into the vertical slots 45 of the upwardly extending arm 40 of the support member 4. These cross beams are prefabricated and the extremity 62 of the hook is fixedly mounted to the beam.
  • One hook is embedded in the flat portion a and the other in stem 5b.
  • the adjacent support beams 5 are arranged to form a contiguous level surface 5' of flat portion 5a and are prefabricated in a fashion that all adjacent members bear against each other in flush relationship and the projecting hooks 60 fit into spaced slots 45 as desired.
  • the front ends 63 also come flush against surface 48 of arm 4a since hooks 60 project outwardly from the surface of front end 63 of beam 5, a distance less than the depth of slots 45.
  • support members 4 are beveled inwardly at 44 along the bottom edge of arm 4a and at 44 of the bottom edge of arm 4b to make the insertion of members 4 into the fresh concrete forming wall 3 simpler.
  • the adjacent members 4 are interlocked by means of a step shaped locking arrangement at edge 46 of adjoining support members 4.
  • a method of forming a support structure over an area to be excavated so that the area can be excavated without interferring with the activities being carried out directly above the excavated area comprising the steps of excavating a pair of laterally spaced guide ditches downwardly to a point below ground level along the opposed longitudinal sides of the area to be excavated; inserting a guide wall into each of the guide ditches; excavating the space between the guide walls along each of the longitudinal sides of the area to be excavated to a desired depth; pouring concrete into the excavated space between the guide walls along each longitudinal side of the area to be excavated to form side support walls with the upper ends of the side support walls being located below ground level; providing prefabricated support members with an upper surface, a step in the side of the support member below its upper surface, a vertical slot in the side of the supporting member above the step, and an opening through the lower part of the support member; placing the prefabricated support members into the upper surface of the concrete forming the support walls before the concrete has set for
  • a method, as set forth in claim 1, comprising the steps of providing projections extending downwardly from the lower surface of the support members, inserting the projections downwardly into the side support walls when placing the support members on the side support walls so that the projections extend into the walls before the concrete sets so that when the concrete sets the support members are integrally secured to the side support walls.
  • a support structure as set forth in claim 4, wherein the bottom surfaces of said first leg and said second leg of said support member secured within said side support walls are beveled inwardly and upwardly, and adjacent said support members are disposed in abutting relationship and the abutting surfaces thereof are provided with a step interlock for effecting interengagement therebetween.
  • T-shaped support beams each comprise a horizontally arranged head portion and a vertically arranged stem portion extending downwardly from said head portion, the lower end of said stem portion being supported on the upper surface of said second leg of said support member, a pair of vertically spaced rods extending outwardly from each.
