Description

[Detailed description of the invention] This invention is a suitable floor surface for reinforcing parts where the floor surface is damaged or broken when heavy vehicles move or at heavy cargo collection points. This invention relates to a reinforcing grid. The floor surface, etc. referred to in this invention is interpreted in a broad sense to include indoor and outdoor road surfaces.

For example, in places such as factories, warehouses, collection points, and wharves, where heavy vehicles come and go, or where heavy cargo is loaded, unloaded, or collected, concrete is simply used to cover the floor or road surface. If the surface is formed with such a structure, it is susceptible to surface wear, cracking, collapse, etc. due to the effects of constantly occurring vibrations and impact loads, and as a result, repairs must be repeated frequently, which is costly both economically and time-consumingly. There was also the problem of large losses. Even if it were possible to prevent internal damage to a concrete floor by placing reinforcing bars inside the floor, the problem still remained that surface damage could not be avoided.

For this reason, the conventional structure was to place reinforcing units of a predetermined area on the floor, each made by combining metal plates in a lattice or net shape, and to pour concrete so that the upper end surface of this unit was approximately flush with the floor surface. It has been adopted. However, even in this case, although there is a reinforcing effect within one reinforcing unit, since the reinforcing units in each unit are simply placed side by side, they do not complement each other's strengths, and the units in each unit As a result, there was a risk of damage to the floor surface between the ends of each unit.

In view of the above-mentioned problems and drawbacks, the present invention has a simple structure, allows the entire structure to be easily and firmly integrated in a continuous manner during construction, and has a lattice body suitable for reinforcing floors, etc. The gist is that vertical plates and horizontal plates each having cutout grooves formed at regular intervals are fitted into each other with the cutout grooves to form a lattice shape, and The ends of at least one of the plates and the horizontal plates are made into protrusions that protrude in length for two or more grids at appropriate intervals, and the ends of the vertical plates or horizontal plates between the protrusions are formed into the above-mentioned portions of the adjacent units. A combination formed by forming a lattice unit as a non-protruding part to which similar protrusions can come into contact, and notch grooves that can be fitted and coupled to the notch grooves of each of the protrusions of a plurality of the lattice units arranged side by side at regular intervals. It is used as a reinforcing lattice body for floors, etc., which is made of a combination with boards.

Hereinafter, the present invention will be described in further detail based on the illustrated embodiments. FIG. 1 is an exploded perspective view for explaining mutually fitting and connecting parts of a lattice unit as an example of the present invention, FIG. 2 is a front view of one component plate of the lattice unit of the embodiment shown in FIG. 3 is an enlarged perspective view of one side of one lattice part of the embodiment shown in FIG. 1, and FIG. 4 is a partial sectional view of the embodiment shown in FIG. 1 applied to a floor surface. In FIG. 1, reference numeral 1 is a lattice unit, and as shown in FIG.
A and horizontal plates 2B are formed by fitting and combining with each other, and the fitting joints are partially or entirely fixed by welding or the like, if necessary. Notch groove 3
is the groove width of the thickness of the component plate 2, the notch depth is half the width of the component plate 2, and the notch is formed perpendicularly from one side at an interval corresponding to the length of one side of the grid, or the notch is The portion is formed to have a width equal to the thickness of the component plate 2, and as the notch becomes deeper, the groove width becomes narrower, resulting in a groove width that is slightly smaller than the thickness width of the component plate 2. In this latter case, the fitting parts of the vertical plate 2A and the horizontal plate 2B are wedged into each other at their narrow widths and become caulked, so that each fitting part can be securely fixed without welding or the like. It has become a common thing. Further, as shown in detail in FIG. 3, claws 4 are formed in the middle part of each notch groove 3 of the component plate 2 by partial punching so as to protrude alternately from different surfaces, and after the punching, holes are formed. 5 is formed. Component board 2 like this
are the vertical plates 2A and the horizontal plates 2B, which are fitted and connected to each other with the notch grooves 3 facing upside down, and each end has two grids on every other sheet (one notch groove 3 exists in the middle). Condition) They are combined and arranged to form a protruding protrusion 1A. Reference numerals 7 and 8 each designate a single-piece connecting plate in the vertical and horizontal directions, in which parallel or tapered notch grooves 3' are formed at predetermined intervals, similar to those described above, on one side of each plate.

Therefore, as shown in FIG. 4, such a lattice unit 1 is constructed by placing reinforcing bars 9 as necessary.
Mortar, concrete, synthetic resin, or
Filling materials such as asphalt concrete and plaster 11
is poured in and dried and hardened so as to match the upper surface of the component plate 2. In this case, lattice unit 1
The combination is made by combining the protrusions 1A of the opposing vertical plates 2A of the lattice units 1, 1 into the non-protrusions of the opposing units 1 alternately from the state shown in FIG. Rear, lateral coupling plate 8
This is done so that the notched grooves 3 and 3' fit together.
Although not shown in the drawings, the connecting plate 8 may be fixed at appropriate locations such as the ends using anchor bolts or the like embedded in the base 10 in advance.

The cross-combination with the protruding portions of each horizontal plate 2B, and the fitting connection with the longitudinal connecting plate 7 through the notched grooves 3, 3',
Do the same as above. After joining, in the case of parallel notched grooves 3, 3', the required joining portions may be fixed by welding or the like.

According to the above embodiment, the protruding parts 1A at the peripheral ends of the units are alternately inserted into the non-protruding parts of the adjacent units, and the protruding parts 1A, 1A of the mutually adjacent units are simultaneously connected by the coupling plate 8. Since the units are fitted and connected, the entire structure is continuously integrated, and strain does not remain between the units, and the entire floor surface on which the units are arranged side by side can be reinforced almost uniformly.

In addition, the floor surface laid as described above will be laid out in a lattice pattern with steel component plates 2 arranged at appropriate intervals, and will be subjected to heavy loads, friction, vibrations, shocks, etc. Even if there is, there is very little abrasion of the floor surface, and in each grid section, the filler 11 enters the holes 5 of the component plate 2, and the claws do not penetrate the filler 1.
1, the constituent plate 2 will not be lifted up due to vibrations, shocks, etc., and each lattice part will act as a contraction joint and an expansion joint, which will prevent cracks, cracks, etc.
Since no damage such as collapse will occur, factories,
It goes without saying that it is extremely effective when applied to areas where heavy vehicles come and go, such as warehouses, collection points, wharves, and construction sites, loading and unloading areas for heavy objects, tunnel walls, and the like.

In the above embodiment, the overall size of the lattice unit 1, the size of each lattice, the width of the component plate 2, etc. can be set arbitrarily, and the claws 4 and holes 5 are formed in all the lattice parts. It doesn't have to be, and it doesn't have to be there at all. Further, the length of the connecting plates 7, 8 is arbitrary, and if the flatness of the base 10 is good, fixing with anchor bolts etc. is not necessarily necessary, and the length of each lattice unit 1 and the connecting plates 7, 8 is Of course, the notch grooves 3, 3' may be oriented in opposite directions during connection.

FIG. 5 is an exploded perspective view for explaining mutually fitting parts of another embodiment of the lattice unit according to the present invention. Reference numeral 21 denotes a lattice unit, which includes vertical plates 22A and horizontal plates 22B. Each constituent plate 22 is formed in the same manner as the constituent plate 2 of the embodiment shown in FIG. A protrusion 21A is formed that protrudes by the length of a lattice (with three notched grooves 23 in the middle), and a short component plate 22 corresponding to at least three lattices is formed in the distal end side notched groove 23 and the inner end side notched groove 23. 'B are fitted and connected, and only the middle notch groove 23 remains as a groove. Reference numeral 28 designates a lateral coupling plate similar to the lateral coupling plate 8 of FIG. 1, in which a cutout groove 23' is formed.

Therefore, in this case, when the protrusions 21A are assembled so as to alternately enter the non-protruding parts of the opposing units 21, the inner notch grooves 23 of each protrusion are aligned in a line, so that there is no problem with respect to them. Lateral coupling plate 2
The notch grooves 23' of No. 8 are fitted and connected. Other points are the same as in the above embodiment. In this example, an even stronger connection between the units is obtained than in the configuration shown in FIG.

In the embodiment of FIG. 5, portions corresponding to the claws 4 and holes 5 in the embodiment of FIG. 1 are omitted, but similar claws and holes may be provided in each lattice portion or a portion thereof.

In addition, the combined assembly of the lattice units of each embodiment can be simply fixed at appropriate locations on the floor subsurface using anchor bolts, etc., and the filler 11 is placed inside each lattice.
It is also possible to use the lattice unit in an exposed state without filling it, and the form of the combination connection of the lattice unit according to the present invention is such that the protruding part of the unit extends beyond the fitting notch groove of the connection plate. If any, the present invention is not limited to the configuration of the above-described embodiments.

As described above, according to the present invention, adjacent lattice units are provided with protrusions having a length of two or more lattices and corresponding non-protrusions at appropriate intervals at the ends thereof. A continuous floor surface can be easily formed by simply butting together the connecting plates formed by forming notched grooves in each of these protruding parts, and the construction efficiency can be significantly improved. At the same time, since the connections between each connected unit are strong and the entire floor surface is continuously integrated, it is possible to provide almost uniform strength to the entire floor surface without accumulating strain at the joints.
