Description

Endorsement rafters, and a method for manufacturing the same

TECHNICAL FIELD The present invention relates to a rafters and a method for producing the same, and more particularly, to a rafters and a method for manufacturing the same, with the outer side of the hanok on the eaves.

In traditional hanok, rafters are used to decorate roofs by being fixed to the bottom of the eaves of roofs protruding from the walls.

In such hanok, wood accounts for overwhelmingly 40% of the total, and 40% of the timber is rafters.

Therefore, in order to reduce the air and construction costs by lightening the roof and wood, the rafters must be improved.

Traditional hanok is characterized by a lot of eaves, and it is also the part that determines the biggest image of hanok.

Therefore, the opinion that do not remove all rafters is not hanok dominated.

Therefore, if only visible exposed cornices are hung on the rafters and the interior is furnished with modern wood, the structure will be stronger, the roof will be lighter, and the timber requirements will be reduced.

In order to solve the above problems, the construction of the prefabricated rafter and its construction method have been proposed.

1 is an exploded perspective view showing a conventional rafters, and is fixed in the longitudinal direction to the lower portion of the eaves 200 through the upper plate fixing means 400, a plurality of rectangular ring bracket 300 consisting of the upper plate, both side plates and the lower plate And, it is mounted while wrapping the square ring bracket 300, the lower portion is composed of a rafter body 500 is fixed to the square ring bracket 300 through the lower plate fixing means 600.

And the rafter body 500 is composed of a hollow portion 501 having an upper opening 502 so that the square ring bracket 300 can be inserted.

In addition, the upper plate fixing means 400 is a horizontal, longitudinal long hole (301, 302) formed in the upper plate of the square ring bracket 300 to fix the square ring bracket 300 to the lower portion of the cornice 200 And a bolt 303 which is penetrated from the lower part of the laterally and longitudinal long holes 301 and 302 to the lower part of the eave 200.

In addition, the lower plate fixing means 600 is provided in the position corresponding to the tab hole 601 provided to penetrate the lower plate of the square ring bracket 300, the lower portion of the rafter body 500 and the tap hole 601 A through hole 602 and a bolt 603 through the through hole 602 in the lower portion of the body 500 to be fastened to the tab hole 601.

Hereinafter, the conventional rafter construction which consists of the above structures is demonstrated.

Figure 2 is a cross-sectional view showing a mounting state of the conventional rafters, first, a plurality of square ring bracket 300 is mounted in the longitudinal direction through the upper plate fixing means 400 in the lower portion of the eaves (200).

That is, by passing the bolt 303 from the bottom to the top through the horizontal and vertical long holes 301 and 302 constituting the upper plate fixing means 400, the bolt 303 is fastened to the lower part of the eave 200 by the square ring bracket. It is to attach the 300 to the cornice (200).

Next, the rafter body 500 is inserted from the bottom of the square ring bracket 300 to the top. That is, the hollow portion 501 having the upper opening portion 502 provided in the inside of the rafter body 500 is inserted from the lower portion of the square ring bracket 300 to the upper portion.

And finally, by connecting the lower plate of the rafters body 500 and the lower plate of the square ring bracket 300 through the lower plate fixing means 600 to finish the construction of the rafters.

That is, by passing the bolt 603 through the through hole 602 of the lower body 500 constituting the lower plate fixing means 600 and then fastening it to the tab hole 601 formed in the lower plate of the square ring bracket 300 The body 500 may be fixed to the square ring bracket 300.

However, when constructing the rafters as described above had the following problems.

First, by fixing the square ring bracket to the eaves through bolts, inserting the rafter body around the square ring bracket, and then constructing the rafter through the process of assembling the square ring bracket and the body, according to the construction process of the rafter There was a problem that the construction efficiency falls.

In addition, as the upper and rear of the rafter body is opened, the strength of the rear side is weak, there is a problem that the rear side wall is shaken due to external causes such as strong wind after construction, noise is generated or the rear side is easily damaged.

In addition, by penetrating the bolt through the eaves in the state of inserting a tool such as a screwdriver or a spanner into the square ring bracket, there is a problem that the tool is interfered with the square ring, which leads to a lot of difficulties in bolting.

Thus, in order to solve the conventional problems as described above, the construction method of the prefabricated rafters for the traditional house and the prefabricated rafters have been proposed.

The conventional prefabricated rafter for the traditional house, as shown in Figures 3 to 6, a plurality of anchor bolts 1 and the top plate mounted in the longitudinal direction so that the bolt portion 11 protrudes in the lower part of the eave 10 In the 21, the assembly contact surface 221 is provided with a plurality of upper assembly through holes 222 through which the bolt part 11 penetrates, and a hollow part 22 having an open rear side is provided therein. The lower assembly hole includes a lower dent groove 231 at a position corresponding to the upper assembly through hole 222, and has a lower assembly through hole 23 having a larger diameter than the upper assembly through hole 231. Through the cylindrical or square cylindrical body (2) and the lower assembly through hole 23 is to be inserted into the upper portion perpendicular to the hollow portion 22 to be in close contact with the lower surface of the upper plate 21 and the upper, lower inside In the upper and lower tab grooves (31, 32) formed assembly pipe (3) and the lower assembly through hole 23 And the lower tab fastening the upper tab groove 32 to the bolt portion 11 of the anchor bolt 1 by rotating the assembly pipe 31 while rotating through the lower tab groove 32 of the assembly pipe 3. It consists of a bolt (4).

In addition, the conventional prefabricated rafter construction method for the traditional house step of mounting a plurality of anchor bolts in the longitudinal direction such that the bolt portion protrudes in the lower portion of the eave (100); The upper plate is formed with a recessed contact surface with a plurality of upper assembly through holes through which the bolt portion penetrates, a hollow part with an open rear portion inside the lower plate, and a lower periphery at a position corresponding to the upper assembly through hole. Step 102 of preparing a cylindrical or rectangular cylindrical body formed with a lower assembly through-hole including a groove, a relatively larger diameter than the upper assembly through-hole and the close contact surface of the body with the lower surface of the cornice While the step of passing through the bolt assembly through the assembly hole of the body 103 and the upper, lower inside of the upper and lower tab grooves are formed through the lower assembly through hole through the lower assembly through the vertically inserted into the hollow part through the lower assembly through At the lower part of the hole, the lower fastening bolt is rotated by fastening to the lower tab groove, and the upper tab groove of the assembly pipe is fastened to the bolt part of the anchor bolt. Characterized by consisting of a (104).

The construction method of the conventional traditional prefabricated rafters and the prefabricated rafters composed of the construction and construction as described above is a structure and method of simply fixing the prefabricated rafters to the eaves via the anchor bolt, the eaves by the weight of the rafters There is a problem of sag, and there is a problem that there is a possibility that rafters fall down due to gusts due to structural instability due to sag of such eaves.
