The invention according to claim 4 has the same streak pattern as the deck material. It is possible to provide a highly homogeneous appearance for use in outdoor structures along with deck materials.

  In the following, the present invention will be described in more detail with reference to the example of the drawings. In the figure, A is a wood-based split-type strut, and the split-type strut A is composed of an aluminum extruded material split-type hollow base 1 and the hollow base. The hollow base material 1 and the attachment body 2 are formed at the both ends in the circumferential direction so as to cover the outer periphery of the fitting arrangement state, which is formed of the other attached body 2 of the aluminum extruded material split mold that is fitted and arranged in the recess 12 of the base body 1. It is assumed that the wood-like resin coating layer 3 is disposed by inflow locking the end portions into the notch grooves 15 and 27 and extruding a wood powder-containing molten resin on each exposed surface of the hollow base body and the attached body, At this time, one of the hollow base body 1 and the attached body 2 is provided with a bent strip 14 with its circumferential end bent at the inner side of the column, and the other with a protruding strip 25 protruding so as to approach the bent strip 14. And the notch grooves 15 and 27 are formed on the bent strips 14 and 14. The resin coating layer 3 is arranged in series on the bent line 14 so as to extend beyond the notch groove 15 toward the inner side of the column of the bent line 14, and beyond the notch groove 27 on the protruding line 25. The ridges 25 are arranged in series at the end of the tip.

  The split-type support A in this example is, for example, suitable for use in supporting the roof of the terrace, the rear end of which is fixed to the outer wall of the building. The hollow base body 1 and the attachment body 2 form a circular column by forming a circular outer periphery, while the attachment body 2 is formed as a vertical rod for flowing rainwater from a rain gutter disposed on the column, and the hollow substrate 1 The fitting arrangement with respect to the recess 12 is a detachable arrangement by snap-in bonding to the hollow substrate 1.

  In this example, the hollow base 1 in the split post A is composed of a large arc portion 11 forming a 3/4 circle arc of the split post A, and an indented inward from the arc portion 11. 11 having a U-shaped recess 12 connecting the 11 and 11 and tapping holes 16 so as to form a quarter-circle pitch including both ends of the arc portion 11 on the inner surface. Each of the pair of small protrusions 13 arranged on the opposing wall as one of the snap-in locking strips is provided, and in the split-type column A, the attachment body 2 having the above-mentioned vertical hook in this example is , A small circular arc part 21 forming a quarter circular arc of the split column A and a middle position near both ends of the circular arc part 21 from the middle position near the both ends of the hollow base 1 so as to block the 1/4 circular opening of the hollow base 1 While having a hollow collar 22 for rainwater flow so as to have a tapered shape, the same At a middle position near both ends of the arc portion 21, a pair of leg portions 23 project outward in the circumferential direction of the hollow flange portion 22, and on the outer surface of each leg portion 23, as a snap-in other locking strip. It is assumed that the arranged arrowhead 24 is provided.

  At this time, the hollow base body 1 of this example is configured so that the center of the arc portion 11 is bent from the tapping hole 16 by bending the circumferential end of the arc portion 11 to the inside of the support so as to support the tapping hole 16. In this example, a bent strip 14 is provided in parallel with the bottom wall of the recess 12 in parallel with the line passing therethrough so as to open in the vicinity of the bent end of the bent strip 14 in the outer circumferential direction. In addition, for example, a notch groove 15 is provided, which has a wedge shape so as to effectively exert an anchor action.

  Further, the attachment body 2 as a vertical rod in this example is configured such that both ends of the circular arc portion 22 in the circumferential direction from the position of the hollow flange portion 22 to the pair of legs 23 in the circular arc portion 21 of the quarter circle are formed on the hollow base body. Similarly, the anchor 25 is similarly wedge-shaped or similar so that the protrusion 25 protrudes close to the bent line 14 and opens toward the front surface at the tip position of the protrusion 25. A notch groove 27 is provided so as to effectively exhibit the action.

  The resin coating layer 3 in the split-type column A is formed on the hollow base 1 and the attached body 2 of the aluminum extruded material, and the arc portion 11 forming the exposed surface in this example using the hollow base 1 and the attached body 2 as a core material. , 21 is formed by extrusion molding of a synthetic resin. In this example, the synthetic resin is made of polyethylene resin, for example, its standard coating thickness, that is, its thickness is about 1 to 3 mm. For example, the distance from the mold is set to 1.5 mm, and the extrusion is performed. At this time, a slight misalignment of the aluminum extrusion material in the extrusion mold, an extrusion error of the aluminum extrusion material, etc. In consideration of the above, the minimum coating thickness, that is, the minimum thickness is set to about 0.5 to 2.5 mm. In this example, the resin coating layer 3 of the hollow base body 1 and the attachment body 2 is extruded. By the surface polishing after molding, the streak pattern 31 due to fine unevenness Some as having been.

  The extrusion molding of the synthetic resin to the hollow substrate 1 and the attachment body 2 is performed by using a mold in the present example in which the melted polyethylene resin is supplied to the arc portions 11 and 21. The melted polyethylene resin is poured into the notch grooves 15 and 27 and hardened to form a projection 32 fitted to the notch grooves 15 and 27, which is used as an anchor. , It is designed to exert its anchor action. At this time, in the hollow base body 1 of this example, a molten polyethylene resin is supplied together with the arc portion 11 beyond the notch groove 15 so as to extend over substantially the entire width of the bent strip 14 parallel to the line passing through the center. Are arranged in series toward the inner side of the support column A of the bent strip 14, and in the attached body 2, with the arc portion 21 beyond the notch groove 27 of the protrusion 25 facing the bent strip 14. Similarly, a polyethylene resin is supplied to cover the tip of the upright strip 26 facing the front surface side defining the notch groove 27, and the tip of the resin coating layer 3 is applied to the bent strip 14 of the hollow substrate 1. In close proximity, for example, the interval is regulated to be as small as possible, for example, 1 mm or less, particularly about 0.5 to 0.8 mm. The surface polishing of the line pattern 31 after extrusion is performed by using a metal brush, for example, so that the surface of the resin coating layer 3 is provided with a line having shallow and fine narrow grooves.

  The hollow base body 1 and the attachment body 2 formed in this way are provided with a pair of leg pieces on the other side of the snap-in on the locking line formed by a pair of small protrusions 13 formed on the opposing wall of the recess 12 on the one side of the snap-in. By inserting the hollow collar portion 22 of the attachment body 2 into the concave portion 12 of the hollow base body 1 so that the locking pieces by the arrowheads 24 arranged on the stripe 23 are snap-in-locked to each other, the attachment to the hollow base body 1 is performed. The body 2 is to be fitted and arranged.

  The split post A is provided with the tapping holes 16 in the hollow base 1 so that caps (not shown) are arranged and fixed at one end or both ends in the longitudinal direction, in this example, at the upper and lower ends of both ends. On the other hand, the attachment body 2 is not provided with the fixing tapping hole, and therefore can be fitted and arranged in the hollow base 1 irrespective of the cap. It can be used as a support for outdoor structures such as terraces and solariums, and the attached body 2 can be removed and then fitted and placed while the hollow substrate 1 is fixed. For this reason, the attachment body 2 is provided with a notch portion in which the front side of the hollow flange portion 22 is partially cut off at the longitudinal end portion, for example, the upper end portion, for example, a notch portion in which the notch edge is covered with resin. Thus, the cut-out portion can be used as a handle portion for removal. For example, by using a tool such as a screwdriver, the snap-in locking with the hollow base body 1 can be achieved by pulling the arc portion 21 of the attachment 2 toward the front side. After removing and removing the foreign matter that has entered the hollow gutter portion 22 from the rain gutter, the fitting arrangement 2 can be placed again by pressing the attachment body 2 from the front side. The attached body 2 can be easily cleaned as necessary.

  The split post A of this example formed in this way has a wood-like resin coating layer 3 arranged by the anchor action with the protrusions 32 on the back surface of the resin flowing into the notch grooves 15 and 27 of the aluminum extruded material as anchors. As a result, it is impossible to bond the aluminum extrudate and the resin coating layer by extrusion molding of the wood powder compounded resin to the aluminum extrudate, but the non-adhesive laminated state is maintained by the anchoring action at each end in the circumferential direction. In addition, the fixing can be made stable and integrated for a long period of time without performing fixing means such as bonding or screwing. The resin coating layer 3 is formed so that the bent base 14 and the protrusion 25, in particular the upright strip 26, which are disposed beyond the positions of the notch grooves 15 and 27 exhibiting the anchor action, are close to each other, so This prevents the fitting part of 2 from being exposed, and the aluminum extruded material to look into the fitting part, or the end of the resin coating layer 3 at the fitting part to peel off from the extruded material and the end to bend At the same time, the vertical rod of the attachment 2 is not exposed on the side of the column, but can be made into a circular column A made of aluminum with a rod that has been integrated into the column to eliminate the sense of incongruity. By having the same streak pattern 31 as that of a generally used deck material, including the vertical rod of the body 2, it is possible to have the same appearance as the deck material. Therefore, the split-type support A is made of wood, so that it has the same texture as the deck material and floor surface used for outdoor construction, and the vertical gutter is integrated so that there is no sense of incongruity and the appearance is possible. Can be improved.

  The illustrated example is as described above. However, the positional relationship between the bent strip and the ridge is reversed between the hollow base body and the attached body, and the ridge cover of the attached body is placed inside the standing ridge. In carrying out the present invention, a hollow substrate is used, including performing the structure, replacing the column with a circular one instead of a rectangle or rectangular, and using the column for an outdoor structure other than a terrace such as a sunroom. , Attachments, notch grooves, resin coating layers, bent strips, ridges, vertical shafts used as needed, snap-in joints, streak patterns with fine irregularities, etc., structure, material, relationship between these, etc. Additions to can be made in various forms as long as they do not contradict the gist of the invention.
