Description

  The present invention provides a natural wood grating for the lid that lays on the gutter so that it can be used in parks and residential areas to take into account the natural environment, contribute to landscape improvement, pedestrian safety, etc., and thinned wood It is related to gratings with natural trees that can be used for forest resources.

The wood grating of the lid laid on the side groove is made by drilling a hole at the end of the wood and integrating it through a pipe, a combination of high strength and corrosion-resistant Selangan butterwood, etc. There are things with the ends fixed to the steel frame, and the outer frame made of wood and the wood fixed to the top surface. The combination with the steel material is a thing that puts the wood on the steel lattice frame and fixed it, etc. is there.

  However, in the above construction method, deterioration of strength due to aging and problems with strength when the vehicle passes, even wooden gratings are used as traffic paths for people and cars, so durability and Wheel load must be taken into account.

  The present invention has been made in view of the above circumstances, and its primary purpose is to make use of the gentleness and warmth of natural trees and to take into account the scenery of parks and townscapes. It is to provide a sense of fulfillment such as moisture.

  The second purpose is to integrate natural wood on top of the ladder-shaped steel material to compensate for deterioration due to aging of the wood with the strength of the steel material, such as tripping and slipping when people and bicycles pass. It is to provide a grating with natural wood that prevents danger and allows safe traffic.

  A third object is to provide a grating with natural wood that can withstand loads (wheel loads) that a vehicle can pass by giving sufficient strength to the steel material on the ladder.

  In order to achieve the first object, according to the invention of claim 1, two steel molds are arranged substantially in parallel, and a ladder in which a plurality of steel molds are arranged substantially perpendicularly to the steel molds arranged substantially in parallel. Making a frame, placing a natural tree on the top surface of the ladder frame, making a cut in a portion that hits one side of the plurality of shaped steels, and joining the ladder frame from the bottom surface using fasteners makes it easy to walk Now, it is a natural wood grating that incorporates landscape improvements.

  In order to achieve the second and third objects, in the invention of claim 2, a steel plate having a round hole is welded and fixed to a plurality of vertically arranged steel molds, and the plurality of steel plates are attached to the lower surface of the natural wood. A cut is made in a portion corresponding to one side of the arranged mold steel, the mold steel is fitted into the natural wood, a washer or a resin packing is sandwiched between the natural wood and the natural wood, and the natural wood with a horizontal hole is long. It is a natural wood grating with a structure that can withstand the passage of cars by compensating for deterioration and lack of strength due to aging of the wood by fixing it with bolts and completely integrating the steel on the ladder and the upper natural wood.

  According to the first to fifth aspects of the present invention, the strength is increased by inserting the cut portion into the wood, inserting the steel mold from below, and using the long bolt and the fastener to integrate and strengthen the connection. It can withstand unbalanced pressures such as torsion and torsion caused by wheels, give safety and satisfaction when people pass, contribute to the improvement of the landscape, and make effective use of thinned wood in the production of natural wood gratings This led to improvements in the forest environment, and also made it possible to easily replace the wood part in consideration of corrosion, damage, etc. due to aging of the wood.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the grating with natural wood according to the present embodiment, natural wood (FIG. 2) processed by sawing is arranged in a lattice shape on a steel frame (FIG. 1) assembled in a ladder shape (FIG. 5). It is integrated with a steel frame assembled on a ladder via a steel plate with holes and joined with a fastener 11 from the lower surface.

  The above-mentioned ladder-shaped steel frame is placed with two L-shaped steels 2 in parallel so that one side faces upward, and a plurality of shaped steels 5 are vertically placed on 2 so that one side faces upward, and are fixed by welding. A steel flat plate with a round hole is placed on the mold steel 5 so as to stand parallel to the mold steel 2 and fixed by welding. At this time, the width of the natural wood 10 and the inner dimensions of the steel flat plate 1 and the L-shaped steel 2 are the same. To do.

  The natural wood 10 is cut into a portion 4 that hits one side of a plurality of vertical steel shapes 5 to cut a bolt hole 3.

  As shown in FIGS. 3 to 5, natural wood 10 is inserted into a ladder-shaped steel frame (FIG. 1) by fitting incisions (FIG. 3), and joined by fasteners 11 from the lower surface. , L-shaped steel 5 or T-shaped steel 7 From the side of the assembled natural wood grating (FIG. 4), a long washer 9 is inserted between the natural wood and the natural wood, and the nut 6 is tightened and fixed. Thus, the natural wood, the ladder-shaped steel material, and the natural wood are united to form a structure that can withstand the weight and impact of the car.

Although the embodiment has been described above, the present invention includes the following.
(1) Use natural wood that has been cut into an arbitrary shape.
(2) Instead of natural wood, use pseudo-trees made of concrete or resin.
(3) Use screws or nails as fasteners.
(4) Insert a washer or resin packing between the natural wood and the natural wood to maintain appropriate spacing and improve drainage.
(5) A cut pattern is added to the top surface of natural wood to prevent slipping during rainy weather.

  The structural diagram which shows the installation state of the ladder frame by the L-shaped steel which is the lower part of the grating with a natural tree concerning implementation carrying, and the steel flat plate with a round hole.   Explanatory drawing of the round hole for inserting the natural tree which is the upper part of the grating with a natural tree concerning implementation carrying, the notch for fitting a lower model steel, and a long bolt.   The side view which combined FIG. 1, FIG.   The side view of the finished product which passed the long bolt through the steel flat plate with round holes and natural wood, and was tightened with the nut, and the figure of the T-shaped steel in the claim.   The top view of the finished product of grating with natural wood, and explanatory drawing which shows the position of the steel flat plate with a round hole, and a washer.
