Definitions

  • the invention relates to a method for constructing a float for at least one building to be placed thereon, which float is at least substantially made of a buoyant material.
  • a drawback of the method that is known from the aforesaid European patent publication is the fact that an unstable float is provided. Said instability may lead to swell-induced rocking of the float, for example, which may result in serious damage being caused to the greenhouse that is present thereon. The known float and the greenhouse that is built thereon may even sink as a result of said rocking of the float. It stands to reason that the aforesaid instability involves economically unacceptable risks.
  • the object of the invention is to obviate this instability drawback, and in order to accomplish that object a method of the kind referred to in the introduction is according to the invention characterized in that a concrete foundation is formed in the buoyant material of the float.
  • a concrete foundation is formed in the buoyant material of the float.
  • the concrete foundation is provided in situ.
  • the construction of the present float can take place in a very efficient and cost-saving manner, which no longer involves costly, labourious and risky transportation of a float that is ready for use from a construction site to the site where the float is to be used.
  • recesses are formed in the float, into which recesses concrete is subsequently poured so as to form the concrete foundation.
  • recesses being communication with each other are formed in the float, wherein concrete is poured into one of the recesses from a central part of the float. This achieves that the concrete is distributed from said one recess in the central part of the float over all the recesses that are in communication with said one recess.
  • the recesses are formed in the float by means of a material-removing operation.
  • Said material-removing operation is a cutting, sawing or milling operation.
  • the float is at least substantially constructed of blocks of a buoyant material, wherein groups of blocks are positioned in spaced-apart relationship so as to form recesses between adjacent groups of blocks.
  • the float is at least substantially constructed of at least two layers of blocks of a buoyant material, wherein blocks in the lower layer abut against each other and wherein groups of blocks in the upper layer are positioned in spaced-apart relationship so as to form recesses between adjacent groups of blocks.
  • the float is at least substantially constructed of at least three layers of blocks of a buoyant material, wherein blocks in the lower layer abut against each other and wherein groups of blocks in the middle layer and the upper layer are positioned in spaced-apart relationship so as to form recesses between adjacent groups of blocks.
  • the buoyant material is a synthetic material, in particular expanded polystyrene, also called “styropor”.
  • a bumper is formed round the float.
  • Said bumper is in particular made up of blocks of concrete and/or blocks of a buoyant material, such as the aforesaid expanded polystyrene.
  • At least one house is built on the float in situ.
  • a greenhouse is built on the float in situ.
  • a water reservoir having a wall of a flexible plastic material is present at the bottom side of the float, which reservoir functions to supply the greenhouse with water.
  • a reinforcement is provided in the recesses before concrete is poured into the recesses.
  • Such a reinforcement can be mounted in the recesses in such a manner as to be spaced from the bottom thereof by means of spacers.
  • a reinforcement consisting of cables is used in the recesses, said cables can be tightened (after pouring and curing of the concrete), e.g. by means of swivels, so as to set up a tensile force in the concrete.
  • swivels e.g. by means of swivels
  • Figs. 1-4 show a preferred variant of the construction of the present float of at least three layers of blocks of expanded polystyrene, with blocks in the lower layer abutting against each other (Fig. 1) and groups of blocks in the middle layer and the upper layer being positioned in spaced-apart relationship so as to form recesses between adjacent groups of blocks (Figs. 2 and 3).
  • Fig. 4 corresponds to Fig. 3, with this understanding that a bumper is provided in Fig. 4.
  • a first (lower) layer 1 having a thickness of 35 centimetres is formed on the water, for which two types of blocks of expanded polystyrene are used.
  • One block type 2 has a length of about 10 m, a width of about 1 m and a thickness of about 35 cm.
  • the other block type 3 has a length of about 5 m and the same width and thickness as block type 2.
  • the width of the float is determined by arranging the blocks in rows of four blocks 2 and one block 3, with the block 3 alternately being positioned on one longitudinal side and on the other longitudinal side of the float, seen in the longitudinal direction of the float.
  • the first layer 1 may be built up of two or more sublayers, with a reinforcement mat in the form of a layer of glass fabric being laid on top of said layer 1.
  • a second layer 4 having a thickness of about 50 cm is laid on top of the first layer 1.
  • Said middle layer 4 is built up of eight groups 5, each consisting of two types of blocks of expanded polystyrene.
  • One block type 6 has a length of about 10 m, a width of about 1 m and a thickness of about 50 cm, whilst the other block type 7 only differs from block type 6 in length (the length of block type 7 is 5 m).
  • the blocks are arranged in alternating rows - seen in the transverse direction of the float - of two blocks 6 being in line with each other on the one hand and one block 6 with two blocks 7 on either side thereof on the other hand.
  • FIG. 2 shows the groups 5 in the middle layer 4 to be so arranged relative to each other that recesses 8 are formed between adjacent groups 5. Said recesses 8 form interspaces, which can subsequently be filled with concrete so as to form the concrete foundation of the float.
  • a third (upper) layer 9 having a thickness of about 50 cm is subsequently laid on top of the second layer 4, with thirty-two groups 10 of blocks of expanded polystyrene being used.
  • Each group 10 is built up of four blocks 11 having a length of about 5 m, a width of about 1 m and a thickness of about 50 cm.
  • the blocks 11 forming a group 10 abut against each other with their longitudinal sides, being interconnected by means of interlocking lips.
  • the groups 10 in the upper layer 9 are positioned in spaced-apart relationship so as to form recesses 12 between adjacent groups 10 of blocks 11.
  • the recesses 12, too, form interspaces which are subsequently filled with concrete so as to form the concrete foundation of the float.
  • Fig. 4 shows the subsequent provision of a bumper 13 on the layer 1 and along the circumferential edge of the whole of layers 4,9, which bumper 13 is built up of blocks of concrete 14 having a length of about 5 m, a width and a thickness of about 1 m.
  • the blocks 14 are made of expanded polystyrene.
  • Fig. 5 relates to a next step, in which a greenhouse 15 is built on the float.
  • blocks of adjacent layers that are positioned above each other may be locked in position with respect to each other.
  • Such locking may for example be effected by means of an adhesive, such as a glue. In the latter case, the blocks that are positioned above each other are glued together, therefore.
