Abstract

(57) [Summary] [Problem] When a stair or the like is made of wood in a civil engineering work or the like, a stair or the like which is easily maintained when the wood is damaged is obtained. SOLUTION: In the case where a lumber is inserted into a lumber and a flat lug is used in combination with a metal lug composed of an L-shape or a T-shape and the lumber is damaged, only the lumber is replaced and used.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is a hardware that can easily change the angle of a stair, a retaining wall, and the like.

[0002]

[Prior art]

 The conventional method of stairs and retaining walls was to create a wall with wood and drive wooden piles into several places in front of it to prevent the collapse of the wall and the outflow of sediment on the back.

[0003]

[Problems to be solved by the invention]

 As described in the prior art, since wood is used for all materials, in the case of long-term use, damage due to corrosion and abrasion is likely to be severe, and maintenance and management of the backside sediment due to collapse of the wall itself will be performed. There was a problem with the surface.

[0004] Further, it is difficult to form an angled wall, and from these aspects, it has been a cause that the frequency of use of wood is difficult to increase in the age of domestic timber.

[0005] The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a metal fitting for increasing the demand for wood by easily replacing wood. It is intended to provide.

[0006]

[Means for Solving the Problems]

 In order to achieve the above objectives, the lugs of the present invention are plug-in type so that the wood part can be easily replaced.If the damage of the wood becomes severe due to corrosion or abrasion, etc., the lumber is stopped. Bolts can be removed and replaced on the spot.

[0007] When damage is found in this way, instead of starting over from the foundation, only the damaged wooden part can be replaced, so that maintenance costs can be reduced and unnecessary outflow of earth and sand can be prevented.

[0008] Furthermore, if this hardware is used, the angle of inclination of the front surface can be easily changed by fixing a support bolt to a hole determined in advance, so that a device for adjusting the angle is not required, and the angle of the river or the like is not required. The range of use of wood can be extended to places where slopes are required, such as revetments and road slope protection.

[0009]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. Metal fittings having the shapes shown in FIGS. 1 and 2 are installed on the left and right, the angle of the front surface is determined to a predetermined angle by support bolts, and wood is inserted between the metal fittings.

[0010] For the wood to be inserted, make holes in advance to allow fixing bolts to pass through at both ends, and process the front part of the wood so that the metal fittings are hidden, or if the metal fittings do not interfere, Use it without processing and insert it one by one into the fixing bolts.

When the wood reaches the upper part of the front plate of the metal fittings, the wood thicker than the length of the remaining fixing bolt is passed through the fixing bolt, and the bolt is tightened to fix the wood so that the gap between the holes is filled as necessary.

[0012] When connecting these widely, metal fittings as shown in Fig. 3 are used for connecting them, and similarly, wood is inserted and added. If the foundation is to be stopped directly by earth pressure, the flat plate (3) must be non-slip, as shown in Fig. 1, or if it has been solidified with concrete, etc., it must be anchored as shown in Fig. 3. Take out the bolts and stop them.

[0013]

[Example] Used for stairs and seawalls in river parks.

[0014]

[Effect of the invention]

 Since the present invention is used as described above, the following effects can be obtained.

If the part of the wood to be inserted between the brackets is damaged, it is only necessary to loosen the bolts holding the wood and replace the damaged wood, eliminating unnecessary rework from the foundation and maintaining At the same time as promoting the effective use of domestic timber (especially thinned timber).

[0016] In the manufacturing process of the metal fittings, by forming in advance a fixing hole for the support bolt according to the angle formed by the front surface, a necessary slope angle is formed simply by fixing the support bolt to the hole corresponding to the angle at the site. As well as being able to be folded down during transportation, work efficiency can be improved.
