The auxiliary supporting member 250 may be omitted. However, in the case of the embodiment shown in FIG. 2, since the base portion 210 of the frame member 200 is formed to be relatively narrow, when the auxiliary supporting member 250 is not provided, ) A large part of the bottom surface is not supported. When the bottom surface of the deck block 400 is not properly supported, there is a problem that the risk of breakage due to an external physical impact increases. Therefore, the auxiliary support member 250 is further applied to the load applied to the deck block 400 It is possible to prevent the deck block 400 from being deformed or damaged.

The auxiliary support member 250 may have a recessed portion 253 along the longitudinal direction. It is preferable that the auxiliary supporting member 250 is fixedly coupled to the upper side of the long side member 100. The auxiliary supporting member 250 may be fixed to the long side member 100 by a fastening member (not shown) The fastening member can be fastened through the recessed portion 253 when the fastening member is coupled to the fastening member 100. When the fastening member is fastened through the recessed portion 253, the head portion of the fastening member stays in the recessed portion 253 and does not protrude upward, so that the fastening member is fastened to the deck block 250, Can be prevented. The auxiliary support member 250 is also preferably made of an aluminum material to prevent corrosion by moisture as in the case of the frame member 200.

The base portion 210 of the frame member 200 is divided into a simple support portion 213 and a long line coupling portion 215 with reference to the coupling portion 220. The division between the simple supporting portion 213 and the joining portion 215 is not a difference in shape but a division according to functional difference of whether or not the joining portion is directly coupled to the joining member 100. [

The joining member 215 is provided with a recessed portion 230 formed along the longitudinal direction of the frame member 200 and a fastening member such as a screw for joining the joining member 215 to the joining member 100, And is tightened through the recessed portion 230. The fastening member is fastened to the joist member 100 through the recessed portion 230 so that the head portion of the fastening member does not protrude upward and interference with the bottom surface of the deck block can be prevented.

As described later, only the joist joining portion 215 is fixed to the joist member 100 by using the joining member at the time of construction of the synthetic deck assembly according to the present invention, The groove 230 may be formed. In this case, the frame member 200 may be formed as a left-right symmetrical shape as shown in FIG. 1. When the frame member 200 is formed in a right-left symmetrical shape, the frame member 200 may be arranged There is an advantage to be able to do.

[ And a protrusion buffer 330 coupled to the protrusion 225 of the coupling unit 220.

The cushioning member 300 is formed in a shape corresponding to the protrusion 225 since the cushioning member 300 is coupled to the coupling unit 220 along the outer contour of the coupling unit 220. That is, the protrusion buffer 330 may be formed in a shape of a triangle, diamond, square, hexagon, or the like.

Since the protruding cushioning portion 330 is engaged with the side recessed portion 420 of the deck block 400, there may be a slight positional change in the vertical direction depending on the position of the side recessed portion 420, Lt; RTI ID = 0.0 > height. ≪ / RTI > When the deck block 400 is installed, a clearance may be formed above the protruding cushion portion 330 between the deck block 400 and the adjacent deck block 400, which may cause cosmetic problems and contamination due to foreign matter inflow. Accordingly, the buffer member 300 preferably further includes an upper extension 340 extending upward from the upper end of the coupling portion 220, so that a clearance between the adjacent deck blocks 400 is neatly formed. It can enjoy beauty and functional benefits.

The deck block 400 is provided with side grooves 420 of a shape and size corresponding to the protruding cushion parts 330 of the cushioning member 300 on opposite sides contacting the frame member 200, . The side groove portion 420 is engaged with the protrusion buffer portion 330 of the buffer member 300 and thus engages with the protrusion portion 225 of the coupling portion 220 of the frame member 200, As shown in Fig.

Hereinafter, a construction method and a maintenance method of an environmentally friendly high strength synthetic deck assembly having enhanced durability according to the present invention will be described.

Since the composite deck assembly is typically constructed to be in a horizontal plane, a foundation frame (not shown) is constructed to allow the composite deck assembly to assume a horizontal plane, regardless of the slope of the ground. The base frame may be a combination of a base post (not shown) and a base beam (not shown). Depending on the state of the structure or the ground on which the composite deck assembly is to be installed, the foundation frame may not be required.

When the foundation frame is applied, the joist member 100 is placed on the foundation frame and joined. It is convenient to work the joining member 100 in the direction of the longer side of the installation site.

When the installation of the long joist member 100 is completed, the frame member 200 is constructed from one end of the long joist member 100. At this time, after the frame member 200 is disposed such that the simple supporting portion 213 of the base portion 210 faces the outer side of the installation portion and the joist fitting portion 215 faces the inside of the installation portion, Thereby joining the joist joining portion 215 to the joist member 100.

The cushioning member 300 can be coupled to the frame member 200 after the frame member 200 is coupled to the joist member 100. [ Alternatively, the buffer member 300 may be coupled to the frame member 200 in advance, and the frame member 200 coupled with the buffer member 300 may be coupled to the joist member 100. However, if the buffer member 300 is formed to cover the entire upper surface of the base 210 of the frame member 200 or at least cover the upper surface of the recessed portion 230 of the long- It may be desirable to couple the buffer member 300 to the frame member 200 after coupling to the long neck member 100. In this case, however, the cushioning member 300 may be preliminarily joined to the frame member 200. At this time, a part of the cushioning member 300 having elasticity may be lifted for a while, The frame member 200 can be coupled to the joist member 100 by using the joining member while the joining member 230 is exposed.

After the assembly of the first frame member 200 is completed, the second frame member 200 is disposed before the deck block 400 is installed. The second frame member 200 is also oriented so that the simple support portion 213 and the long line coupling portion 215 are located in the same direction as the first frame member 200. [ The buffer member 300 is also engaged with the second frame member 200.

Next, the deck block 400 is disposed between the first and second frame members 200. At this time, the position of the second frame member 200 is adjusted so that the upper surface of the base portion 210 of the second frame member 200 can support the deck block 400.

After the deck block 400 corresponding to the length of the frame member 200 is disposed and the second frame member 200 is pressed toward the first frame member 200, So that it can be firmly fixed by the protruding cushion 330 of the protruding cushion 330. Next, the joist joining portion 215 of the second frame member 200 is coupled to the joining member 100 using the joining member. This completes the installation up to the second frame member 200.

The deck block 400 and the frame member 200 may be repeated by repeating the above steps and arranging the deck block 400 of the last row and joining the last frame member 200 to the long neck member 100 The construction of the composite deck assembly according to the present invention is substantially completed.

Depending on the construction site, it may be necessary to install the finishing material along the rim of the synthetic deck assembly completed as described above. When the finish material is applied, the synthetic deck assembly construction is completed.

When a part of the deck block 400 in the completed composite deck assembly is broken and maintenance is required, the operation can be performed more easily than when the deck block 400 is constructed. That is, after removing a part of the finishing material of the synthetic deck assembly rim without disassembling the frame member 200 from the joist member 100, the deck blocks in the row including the deck block to be replaced are removed from the frame member 200, And can be pulled out to the outside. When the broken deck block is removed, the unbroken deck block and the new maintenance deck block can be slid along the frame member 200 again. The maintenance work is completed when the deck block is fully inserted and the removed finishing material is reassembled. Despite the robust construction of the composite deck assembly, the maintenance work can be carried out relatively easily, which saves time and money, which is very economical.
