Definitions

  • This invention relates to a method of constructing a concrete structure, in which metal nets, for instance expanded metal, are used for a framework and are left in or on the surface of the concrete structure.
  • support members and metal nets having comparatively high rigidity such as expanded metal, ribbed expanded metal lath are used in lieu )of the conventional framework which consists of frame plates and support members such as batters and pillars supporting the frame plates.
  • a concrete framework is first formed by attaching the metal nets to the support members, then concrete is placed into the frame defined by the metal nets, and the support members alone are removed with the metal nets left in or the concrete after the solidification thereof. If necessary, reinforcing bars may be provided in the space defined by the metal nets before ⁇ lacing concrete.
  • the time necessary for the manufacturing and assembling of frameworks can be reduced, and particularly the operation of disassembling the framework can be amplified or extremely reduced, so that it is possible to simplify the construction, save labor thereof and greatly reduce the term thereof. Further, the operations of assembling the framework and attaching the metal nets are very simple and do not require any skilled worker.
  • the invention is set out in claim 1.
  • the present invention has an object of obviating the drawbacks discussed above by the provision of a method of constructing a concrete structure, which uses metal nets in lieu of frame plates to thereby permit simplification of the construction, saving of labor therefor .and great reduction of the term thereof.
  • each channel-like pillar 1 has a web 2 having a plurality of longitudinally elongate slots spaced apart in the longitudinal directions. Its opposite side flanges 3 each have a plurality of holes 4 spaced apart a suitable distance in the longitudinal directions.
  • Clamp members 5 are secured to the pillar 1 at the upper and lower ends thereof. More specifically, a clamp member 5 is secured by a bolt and a nut to the outer surface of one side flange 3 at one end, and another clamp member 5 is secured in the same way to the outer surface of the other side flange 3 at the other end.
  • the clamp member 5 is formed from a flat plate and has a stepped portion formed at its longitudinal center. It is secured by clamping the nut on the bolt which is inserted through a hole formed in it and a hole 4 formed in the side flange 3. At each end of the pillar, the clamp member 5 defines a small gap with the corresponding outer surface of the side flange 3.
  • Pillars 1 as described above are erected in upright pairs in two rows such that their side flanges 3 oppose each other.
  • the opposing side flanges 3 are those, to which the clamp members 5 are secured at the upper end.
  • the pillars 1 of a pair are spaced apart by a spacer member e.g., a steel rod.
  • the pillars 1 in a row are connected by a batten 6 extending at right angles to the line forming the pair of pillars.
  • the batten 6 has an L-shaped section.
  • One of its arms has a plurality of longitudinally elongate slots 7 spaced apart in the longitudinal direction. Its slotted portion is clamped between the clamp member 5 and associated side flange 3 of each pillar 1.
  • the other arm projects toward the other row of the pillars 1.
  • the pillars 1 in each row are also connected at their lower end by similar L-shaped batten with the arm without slots 7 clamped between the clamp member 5 and corresponding side flange 3 of each pillar 1 and the slotted arm projecting in the direction away from the other row of pillars 1.
  • Parallel metal nets 8 are stretched over the facing sides of the pair rows of pillars 1.
  • Fig. 6 shows a metal net mounting snap 9. It is made of vinyl chloride but it may also be made of other synthetic resins or rubber. It has a disc- like head 10 and a plurality of locking portions 11 perpendicularly projecting from one side of the head 10.
  • the locking portions 11 are four in number and define a cross-shaped space in section. Each has an outward projection at its mid-portion.
  • the projection 12 is smoothly raised from the rest-of the locking portion 11 and smoothly terminates therein at the other end.
  • the metal net is attached to the pillars 1 by the snaps 9 in the following way.
  • Meshes of the metal net 8 are fitted in the locking portions 11 of the metal net mounting snaps 9, and then the snaps 9 are inserted into the holes 4 of the pillars 1.
  • the locking portions 11 have the projections 12, and as they are inserted the outer diameter of the assembly of the projections 12 is reduced by an amount corresponding to the cross-shaped space so that the projections 12 can be pressure inserted through the hole 4.
  • the projections 12 clear the hole, they are restored to the initial state by the elasticity of the locking portions 11.
  • the metal net mounting snap 9 can not be readily removed. In this way, the metal net 8 can be held attached to the pillars 1 by the head 10 of each snap 9.
  • the battens 6 are connected together to connect adjacent C-channel-shaped pillars by lapping a connecting member over opposed end portions of the battens and securing the connecting member by inserting bolts through the slots 7.
  • the batters 6 connecting the lower ends of the pillars 1 are secured to a concrete subslab by passing concrete nails or the like through the slots 7 and driving them into the concrete.
  • FIGs. 7 to 11 show a different embodiment )of the present invention.
