Definitions

  • This invention is particularly applicable to the construction of large-scale trusses on the bottom of the sea for use as fishing grounds or other types of structure used in the sea.
  • One of the particularly advantageous application of the truss in accordance with this invention is an auxiliary structure around an observation instrument or other kind of instrument provided in the sea for protecting the same from the influence of wave motion.
  • the structure must have small resistance to the flow of sea water so that its position in space will'remain fixed against the sea water flow. Further, the construction must have good versatility in shape. particularly in the case where the construction is used as an auxiliary structure for protecting an instrument or the like in the sea.
  • the principal object of this invention is to provide construction elements which can be assembled into a truss structure which constantly maintains its position in space.
  • Another object of this invention is to provide construction elements for framing trusses which are rigid enough to maintain their position and at the same time elastic enough to maintain their form against the influence of wave motion.
  • Still another object of this invention is to provide construction elements for framing trusses which have small surface area so as to have as small fluid resistance as possible.
  • a further object of this invention is to provide construction elements for constructing trusses which can be assembled in a variety of shapes as desired so that the constructed truss can be made to conform to the contour of the object provided in the sea or can be formed in any desired shape.
  • a still further object of this invention is to provide construction elements for framing underwater trusses which are light in weight and accordingly are able to form large-scale trusses in the sea.
  • a still another object of this invention is to provide construction elements for constructing underwater trusses which have substantially the same specific gravity as that of sea water so that they can easily be assembled in the sea and a great weight of the trusses may not be exerted on the elements in the sea.
  • the construction elements in accordance with this invention basically comprise spherical elastic joint members having a plurality of engaging holes over the whole surface thereof, and web members having elastic portions at both ends thereof to be engaged with the holes of said joint members.
  • the joint members and the web members are made so light in weight that the specific gravity thereof is substantially the same as that of sea water.
  • the web members are preferably made hollow in order to save material and make them light in weight.
  • FIG. I is a partial longitudinal sectional view showing basic elements of the construction elements in accordance with a simple embodiment of the present invention.
  • FIG. 2 is a perspective view of a basic truss unit constituted by the joint members and the web members of the construction elements of the present invention

  • the head member 13 has a hole 13b at an end of a spherical body portion 13a so that the end 12a of the tension member 12 can be inserted therein and tightly fixed thereto.
  • the spherical body portion 13a may be either rigid or elastic. In case that it is rigid, the joint member 2 must be elastic so that the head member 13 of the web member 1 may be snapped into the hole 2a of the joint member 2 by elastic deformation of the joint member 2.
  • the web member I should float or almost float in the water or sea water so that it may be easily handled in the water with small force.
  • the tension member 12 is not a wire rope but a rigid member, foamed urethane 14 may be used to fill in the space between the hollow steel pipe and the tension member 12 so as to make the specific gravity of the web member 1 as a whole substantially equal to that of the sea water,
  • the tension member 12 tensioned in the web member 1 may be a fabric rope made of polypropylene.
  • the spherical joint member 2 is provided with a plurality of joint holes 2a having a narrowered opening 2b for holding the spherical head 13 of the web member 1.
  • the hole 2a holds the head 13 of the web member 1 with a holding force strong enough to keep the web member joined with the joint member when the .joint members 2 joined at the opposite ends of the web memher 1 are pulled apart to strongly tension the rope 12.
  • the spherical joint member 2 is preferred to be elastic, but may be rigid when the head 13 of the web member 1 is elastic enough to easily snap into the hole. In order to prevent the head from easily being removed from the hole, the shape of the head 13 is preferred to be conical or triangular rather than spherical.
  • the foundamental unit of the trusses constituted by the above elements is a tetragonal unit as shown in FIG. I
  • FIGS. 3 to 8 Another preferred embodiment of this invention is illustrated in FIGS. 3 to 8.
  • the head of the web members In order to construct a largescale truss which is used for resisting a large force of wave impact or flow of sea water, the head of the web members is required to be tightly held by the hole of the joint member. Accordingly, a lock means is necessitated at the head of the web member.
  • a web member 3 in accordance with the second embodiments of this invention comprises a hollow tubular portion 3a, a pair ofa head portions 3b provided at the opposite ends thereof, and a wire rope 3c extendingthrough the tubular portion 3a and tensioned between the head portions 3a.
  • the hollow tubular portion 3a comprises, in this embodiment, a rigid steel pipe 31 and a plastic protective coating 32.
  • the pipe 31 may be madeof concrete or plastic so long as it has strong rigidity and sufficient compressive strength against the impact of waves in the sea.
