As described above, in the processing step (S20), the width of the protrusion 12 is formed to be larger than the width of the groove 11. Therefore, in the step (S42), the protrusion 12 is inserted into the groove 11 and restrained. By fitting the adjacent frame member 1 can be assembled more firmly.

It may be fastened (coupled) to be reciprocally movable along the longitudinal direction of the rod 51 .

At this time, the pressing device 5 may include a transfer unit 54 connected to the pressing unit 53 (eg, the pressing part 532 ) to move the moving part 531 on the rod 51 . .

The bolt 543 may have a longitudinal direction parallel to the longitudinal direction of the rod 51 , and when the bolt 543 rotates in one direction with the longitudinal direction as a central axis, the fixing part 541 . Since the position of the nut 542 provided in the nut 542 is fixed, the bolt 543 can move in an upward direction or a downward direction, and when it rotates in a direction opposite to the one direction, it can move in a downward direction or an upward direction.

Therefore, the pressing part 532 connected to the bolt 543 can reciprocate along the longitudinal direction of the rod 51, and through this, the separation distance between the pressing part 532 and the extended part 522 can be adjusted. The skeletal members 1 disposed between the 532 and the extended part 522 can be pressed.

As described above, it was said that the skeletal members 1 may include at least one of the groove 11 and the projection 12, and the width of the projection 12 is formed to be larger than the width of the groove 11, and it is said that it is a force fit. , as described above, since the distance between the pressing part 532 and the extended part 522 is adjustable, it is possible to more easily press the protrusion 12 into the groove 11, so that the neighboring skeletal members 1 can be seen more easily. It has the advantage that it can be firmly assembled.

It was said that the fixing step (S50) may include a step (S52) of driving a pin into the neighboring skeletal member (1). The step (S52) may be performed by the pin gun 6 firing the pin.

Step (S52) is a process for permanently fixing the frame members 1 by driving pins into the furniture 8 assembled and temporarily fixed in the step (S40). The pin gun 6 is commonly used in the field, and a more detailed description will be omitted.

As described above, when the present step includes the step (S51), even if the pin is fired to the frame member 1 in the step (S52) to be hit, the frame members 1 are shaken by the pressing device 5. There is an advantage in that it is possible to manufacture a more precise furniture 8 even by repeatedly performing the step (S52).

Meanwhile, the pressurizing device 5 may include a waterproofing membrane G provided on the support part 52 . The waterproofing membrane (G) includes a water leak detecting means (G2) provided on the upper portion of the support part (52) and a waterproofing means (G1) provided on the upper portion of the water leak detecting means (G2).

The waterproofing film G2 may further include an adhesive layer (not shown) for attaching the support 52 and the leak detecting means G2 to each other, and the adhesive layer (not shown) may include an acrylic adhesive.

The waterproofing means (G1) includes 100 parts by weight of a propylene ethylene copolymer (or ethylene-propylene copolymer), and the propylene-ethylene copolymer is employed to impart elasticity.

In addition, the waterproofing means (G1) includes 60 parts by weight of a mixture of diisocyanate and polyol, which was used to impart waterproofness, and when the mixture of diisocyanate and polyol is less than 60 parts by weight, lubricity and surface coating properties are lowered and when it exceeds 60 parts by weight, the lightness of the entire waterproofing layer is reduced.

Aluminate is added to improve the bonding properties and cohesiveness of each component of the waterproofing means (G1), and when the bonding aid is less than 4 parts by weight, the mixing speed is lowered, and when it exceeds 4 parts by weight, mechanical properties and lightness this may be lowered.

Of course, the waterproofing means (G1) may further include an acrylic adhesive to improve adhesion with the leak detection means (G2).

When the water leak detecting means G2 is described in more detail with reference to FIG. 9, the water leak detecting means G2 is provided on the waterproof means G1 and has a lower conductive layer formed with a plurality of support grooves G211 on the upper surface ( G21), the insulating layer G22 provided on the lower conductive layer G21, the upper conductive layer G23 provided on the insulating layer G22, and the insulating layer supported by the support groove G211 The absorption expansion part G24 disposed in the layer G22, the lower conductor G25 connected to the lower conductive layer G21, the upper conductor G26 provided on the absorption expansion part G24, and the lower part A conductive line G27 electrically connecting the conductor G25 and the upper conductor G26 may be included.

Here, each of the lower conductive layer G21, the upper conductive layer G23, the lower conductor G25, the upper conductor G26, and the conductive wire G27 may be formed of a conductive film such as copper or aluminum or a metal material. can The insulating layer G22 may include, for example, a plurality of polymer resins having a granular shape. That is, a plurality of polymer resin particles are disposed between the lower conductive layer (G21) and the upper conductive layer (G23) so that the lower conductive layer (G21) and the upper conductive layer (G23) are in a state in which the absorption expansion part (G24) is not expanded. to separate

The absorbent expansion part (G24) is formed of an endothelium (G242) formed of cotton fabric and hemp woven fabric wrapped around polyacrylate (G241), polyacrylate (G241), and an outer shell (G242) surrounding the endothelium (G242). G243).

The absorption expansion part G24 is designed to absorb and expand the water when it comes into contact with water, and the water may be absorbed into the polyacrylate G241 by penetrating the endothelium G242 and the outer shell G243. The polyacrylate (G241) absorbs the water that has passed through the outer shell (G243) and the endothelium (G242) and expands, thereby increasing the volume of the absorption expansion part (G24). In this way, since the water leak detection means (G2) can absorb water by including the absorption expansion part (G24), it is possible to improve the waterproofness.

The lower part of the upper conductor G26 may be fixed to at least one of the outer shell G243 and the inner shell G242 by a conventional method used in the relevant field, such as a strong adhesive.

Meanwhile, the upper conductive layer G23 may include a plurality of funnel-shaped hoppers G231 . Water may be introduced into the inlet G231a of the hopper G231 and discharged through the outlet G231b. In this case, the plurality of outlets G231b of each of the plurality of hoppers G231 may be disposed at positions corresponding to the central portions of each of the plurality of support grooves G211 in which the absorption and expansion parts G24 are disposed.

The width of the upper conductor G26 decreases from the lower side to the upper side, but the width of the upper end of the upper conductor G26 is smaller than the width of the outlet G231b, and the width of the lower end of the upper conductor G26 is the absorption expansion part ( It may be smaller than the width of G24).

Referring to FIG. 9A , the absorption expansion part G24 does not expand without absorbing water, so that the lower conductive layer G21 and the upper conductive layer G23 are spaced apart by the insulating layer G22. is in a state of being Accordingly, since no current flows from the lower conductive layer G21 to the upper conductive layer G23 or from the upper conductive layer G23 to the lower conductive layer G21, it can be confirmed that the leakage does not occur.

If water accumulates in the left area (hereinafter (the first area A1)) (the left area of FIG. 9 ) based on the boundary line DL of the neighboring hopper G231 in [A] of FIG. 9, the hopper G231 ), the water in the first area A1 may be collected.

Water from the hopper G231 disposed in the first area A1 is discharged through the outlet G231b and moves downward through the space between the polymer resin grains, and is wider than the outlet G231b (left and right direction based on FIG. 9 ) length) is pulverized at the upper end of the small upper conductor G26 and is absorbed by the absorption expansion unit G24 by moving downward.

As described above, since the width of the upper end of the upper conductor G26 is larger than the width of the outlet G231b, the water droplets discharged from the outlet G231b may not accumulate at the upper end of the upper conductor G26, and the upper conductor Since the width of (G26) increases toward the lower side, water can move downward. At this time, as described above, since the width of the lower end of the upper conductor G26 is smaller than the width of the absorption expansion unit G24, the water moving downward through the upper conductor G26 moves to the absorption expansion unit G24 and is absorbed. can be

When the water flowing downward through the upper conductor G26 passes through the outer shell G243 and the inner shell G242 of the absorption expansion part G24 and is absorbed into the polyacrylate G241, the polyacrylate (G241) is The upper conductor G26, which expands within a few minutes and is fixed to the upper portion of the absorption expansion unit G24, moves the polymer resin particles upward and comes into contact with the upper conductive layer G23. Through this, current flows through the upper conductive layer G23 and the lower conductive layer G21, and it can be determined that a leak has occurred by checking the current through an ammeter or the like.

As described above, it was said that the outlet (G231b) of the hopper (G231) may be disposed at a position corresponding to the central portion of the support groove (G211). Leakage can be identified by using the expansion part G24 to a minimum. That is, since the absorption expansion part G24 can be disposed only in the support groove G211 without the need to be disposed on the upper surface of the lower conductive layer G21, material savings can be achieved.

In addition, by dividing the upper conductive layer G23 through the boundary line DL formed by the neighboring hopper G231, any one of the plurality of regions (for example, the first region as shown in [B] of FIG. 9 ) (A1)) can be identified, so only the leaked area can be repaired.

In more detail with reference to [B] of FIG. 9, the first of the hoppers G231 disposed in each of the first area A1 and the second area A2 (the area on the right with respect to the boundary line DL) When only the absorption and expansion part G24 disposed in the first area A1 expands due to the accumulation of water only in the hopper G231 disposed in the area A1, the upper conductive layer G23 and the lower portion of the first area A1 are It can be confirmed that only the conductive layer G21 is energized and leakage occurs only in the first area A1, so that only the first area A1 needs to be repaired, so that the repair process can be simplified ( Insulation is preferably provided between G231)).
