Description

[Detailed description of the invention]

(Industrial Field of Application) The present invention relates to a frame material and a frame wall including this frame material. The invention relates, for example, to a framed wall that can be made higher, and to a framing material for constructing it. (Prior art) New Zealand Patent Application No. 195408 (Australian Patent Application No.
76710/81) is disclosed in the specification. Various framed walls are disclosed herein having framing members that include supports that allow the framed wall to be built higher. The support has a pair of opposed notches that extend into one of the two vertically adjacent depth frames at any location along its length and across a portion of the support. The material is positioned between two vertically adjacent depth frame members. This support consists of approximately rectangular wooden blocks. SUMMARY OF THE INVENTION The prior art supports having a pair of opposing notches described above are difficult to manufacture as described in the specification of the New Zealand patent application. This support provides some support between the vertically adjacent depth frame members, but since the support members are arranged to intersect with the depth frame members, the length corresponding to the thickness of the support members is This support is by no means sufficient or reliable, since the depth frame members are only mutually supported. Furthermore, this support in the prior art is subject to displacement during filling of the at least partially erected framed wall with backfill fill material. (Means for Solving the Problem) According to the first invention of the present application, the depth frame material, the front frame material, and the back frame material are included, and the depth frame material, the front frame material, and the back surface frame material are included. is formed into a substantially rectangular cross section, and the depth frame material is alternately stacked so as to intersect with the front frame material and the back surface frame material to form a plurality of layers, Each of the depth frame members has an upper surface and a lower surface, and a notch is formed in the upper surface and the lower surface at both ends of the depth frame material, and the notch in the upper surface is connected to the notch in the lower surface from above. is adapted to receive the front frame material and the back frame material from below, and a support member is disposed between the adjacent depth frame materials placed in the vertical direction, and the support material is arranged between the depth frame materials and Longitudinal protrusions and grooves that fit into the protrusions are formed on the upper and lower surfaces of one and the other of the support members, respectively, to fix the positional relationship between the depth frame member and the support member. A framework member is provided that is adapted to. According to the second invention of the present application, the frame member includes a depth frame member, a front frame member, and a back frame member, and the depth frame member, the front frame member, and the back frame member have a substantially rectangular cross section. In a framed wall in which the depth frame members are alternately stacked so as to intersect with the front frame member and the back frame member, each of the depth frame members has an upper surface and a lower surface, and the depth frame members Cutouts are formed in the upper and lower surfaces at both ends of the frame, and the cutout on the upper surface receives the front frame material and the back frame material from above, and the cutout on the lower surface receives the front frame material from below. A support member is arranged between the adjacent depth frame members placed in the vertical direction, and one and the other of the depth frame member and the support member have a longitudinal direction on their upper and lower surfaces. A protrusion and a groove that fits into the protrusion are respectively formed to fix the positional relationship between the depth frame member and the supporting member, and the frame member is further filled with a filler material. A framed wall is provided which is characterized by: (Operations and Effects of the Invention) In the present invention, longitudinal projections or grooves are formed on the upper and lower surfaces of the support material, while longitudinal grooves or projections are formed on the upper and lower surfaces of the depth frame material. These protrusions and grooves are adapted to fit into each other, so that the support member can support the depth frame members over their longitudinal length, providing sufficient and reliable support. I can do it. In addition, since the depth frame material and the support material do not extend to cross each other, but extend parallel to each other, there is a risk that the support material may shift when filling the frame wall with filler material, that is, backfill material. There are few. This is because the support material crosses the depth frame material and both ends thereof do not protrude from the depth frame material. Further, both ends of the depth frame material are provided with notches, and the front frame material and the back frame material are received in these notches and stacked, so that the depth frame material, the front frame material, and the back frame material are stacked. Stacks tightly. In addition, the support material as described above is not particularly difficult to manufacture and can be manufactured at low cost. The support material also serves as a spacer when subjected to a load, but the original role of the support material is
This involves firmly assembling and fixing adjacent depth frame members together. According to the present invention, it is possible to make a frame wall higher than the frame wall disclosed in the specification of the New Zealand patent application, and it is possible to make a frame wall that is higher than the frame wall disclosed in the specification of the New Zealand patent application, and it is possible to make a frame wall that is higher than the frame wall disclosed in the specification of the above-mentioned New Zealand patent application. Because it will definitely be done. (Example) Referring to FIGS. 1 and 3, a state in which a frame material according to an embodiment of the present invention is being assembled is shown in order to assemble a frame wall according to an embodiment of the present invention. Referring now to FIG. 2, there is shown an end view of a framed wall constructed by the method shown in FIG. The frame members include a depth frame member 3, a front frame member 7, a back frame member 6, and a support member 1. These frame members are made of wood and have a substantially rectangular cross section. Each of the depth frame members 3 has an upper surface and a lower surface,
Notches 5 and 4 are provided on the upper and lower surfaces at both ends.
is formed. A front frame member 7 is received in the cutout portion 5, and a back frame member 6 is received in the cutout portion 4, and these are stacked alternately so as to intersect to form a plurality of layers. A support member 1 is arranged between adjacent depth frame members 3, 3 placed in the vertical direction. Grooves 8, 8 are formed in the upper and lower surfaces of the depth frame member 3 in the longitudinal direction. On the other hand, projections 2 and 2 are provided on the upper and lower surfaces of the support member 1 in the longitudinal direction.
is formed. The groove 8 and the projection 2 are fitted to fix the positional relationship between the depth frame member 3 and the support member 1. Such projections 2, 2 provided on the support member 1 are easy to machine. However, a groove may be formed on the support member 1 and a protrusion may be formed on the depth frame member 3. The support member 1 and the depth frame member 3 extend vertically along the wood grain, and manufacturing becomes easier if the protrusion 2 and groove 8 are formed to extend vertically along the wood grain. The illustrated front frame material 7 and back frame material 6 have grooves on the top and bottom surfaces, but in order to facilitate mass production, the grooves 8 are formed on the frame materials using the same shaping machine. This is because the depth frame material 3, front frame material 7, and back frame material 6 were then manufactured.
Only the support member 1 needs to be manufactured using a separate machine. Regardless of whether it is to act as a retaining wall or a decorative wall, it is necessary to provide a suitable foundation for the framed wall according to the invention. Facing walls are suitable to be provided where the embankment to be maintained is essentially stable. Such decorative walls provide protection against water flow and weathering. In addition,
The framework material of the invention is filled with a filler, ie a backfill material. According to a preferred embodiment of the present invention, the length of the depth frame member 3 is preferably selected from among 550 mm, 733 mm, 825 mm, 1100 mm and 1375 mm. These depth frame members 3 have a rectangular cross section of 92 mm x 46 mm, and the depth frame members 3 are preferably made of chemically treated Pinus Radiate. The frame wall shown in the end view in Figure 4 was constructed at a height of 6.1276 m above the ground by assembling the deep frame materials with a length of 1375 mm and a center spacing of 550 mm. In Figure 4, the number of supports per depth frame (HSB/H) is zero (0 HSB/H), one (1 HSB/H), or two depending on the height of the entire frame wall.
An embodiment with two (2 HSB/H) variations is shown. The slope of this framed wall is 4/1. Figure 4 also shows the overload angle β (0°, 10°, 20°, or
38°) is also shown. It is believed that the retaining wall will be overloaded by the backfill material loading. It is also believed that the soil should be retained above one horizontal plane extending rearward at the same level as the top of the retaining wall by a distance equal to the height of the retaining wall. The internal friction angle (0°, 25°, 30°, 35°, 40) is a measure of the frictional resistance to shear between soil particles and is determined by soil density and particle shape. The finer the particle size, the smaller the friction angle.
The friction angle of clay and silty soils is smaller than that of gravel. The preferred positioning and number of supports per depth frame for the overload angle β and the friction angle thus defined are shown in Table 1.

[Table] The backfilling material in this wall is crushed stone that will not be broken by weathering and can be drained freely without being washed away by water currents. The stones should be small enough so as not to damage or displace them. The ideal stone size is considered to be well-sorted stones with a diameter of 20 mm to 100 mm (including well-mixed stones of intermediate sizes).
