Seismic reinforcement type wooden building with prestressed tension material and its construction method

The present invention relates to a seismic reinforcement-type wooden building and a method of construction thereof in which prestressed tension material is introduced, and more particularly, by using thinning or cutting materials in the pillar member of wood used for wooden building, as well as preventing waste of resources. It is possible to minimize the loss rate, to ensure that the column member to be stably coupled to the ground or the top of the pedestal via the column fixed hardware, and to combine the column member and the beam member by the coupling method between the hardware while prestressing the beam member The present invention relates to a seismic reinforcement type wooden building with a prestressed tension material that can be installed to improve the stability of a wooden structure caused by an earthquake or typhoon and a construction method thereof.

Although modern buildings are commonly used in reinforced concrete, masonry, and steel framed constructions, they have recently been upgraded to traditional or modern styles to construct wooden building structures. In particular, wood has been used in accordance with public awareness of well-being and the effects of sick house syndrome. The building is in the limelight.

In addition, for the harmony of nature and aesthetics, timber is used a lot in the construction of bridges, coffee beans, etc. in tourist spots and parks, and its usage is increasing.

In particular, structural aggregates are made of high dimensional stability and structural reliability by removing small pieces of wood such as knots, by bonding small-sized wood to each other to form a large horn. It can adjust the length, thickness, width, etc. according to usage, and it is used as structural pillars and beams because it has less distortion of warpage and cracking than solid wood, and it is made to replace large diameter wood, which is expensive and difficult to obtain. .

Hereinafter, the seismic reinforcement type wooden building in which the prestressed tension material according to the present invention is introduced will be described in detail. In the foregoing description, when it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description will be omitted.

The seismic reinforcement-type wooden building in which the prestressed tension material is introduced according to the present invention has a pillar member 200 installed perpendicular to the ground to support the roof 100 as shown in FIGS. 1 to 6, and the pillar member 200. The hollow pillar reinforcing member 300 is installed to be inserted into the reinforcement groove 230 of the) and the beam member 400 for interconnecting the pillar member 200.

The pillar member 200 is installed perpendicular to the ground to support the roof 100, but a plurality of aggregated wood side surfaces are interconnected so that a reinforcement groove 230 is formed in the longitudinal direction at the center thereof.

Here, the aggregate wood 220 is formed in a longitudinal direction by laminating a plurality of lamina (lamina), by curing the side of the aggregate wood as described above by curing the pillar members of various forms such as circular, octagon, square, etc. The reinforcement groove 230 is formed at the center of the pillar member 200 due to the mutual coupling of the aggregated wood.

At this time, the aggregate wood 220 may be formed to have a structure in which the lamina is gradually bonded in width toward the inner surface direction from the outer surface in the cross-section bonded to each other.

As described above, the pillar member according to the present invention can minimize the material loss generated during fabrication of the pillar member according to the aggregated wood 220 to which lamina is bonded, thereby obtaining resource saving effects. Since large-diameter timber can be manufactured using domestic timber, which is mostly caliber standard, large-diameter timber can solve the problem of local outflow depending on imports.

At this time, the pillar member 200 has a fitting groove 240 to be fitted to the pull-out bracket 310 integrated with the column reinforcing member 300 to be described later is formed a predetermined length from the upper side to the lower side, the pillar The lower side of the member 200 may be formed with the insertion hole 250 of the handle to allow the end of the floor beam 110 for interconnecting the pillar member 200 to be forcibly fitted.

In addition, the pillar member 200 is installed to be fixed via a column fixing hardware 500 that is installed perpendicular to the ground. That is, the pillar fixing hardware 500 is installed to be upright by connecting to the base plate 560 that is seated and fixed to the ground or the base pile forcibly pressed into the ground, and a plurality of pillar fixing hardware 500 in the longitudinal direction Connection grooves 510 are formed.

The pillar fixing hardware 500 is installed so that the pillar fixing hardware 500 is fitted to the pillar reinforcing member 300 installed inside the pillar member 200 in a state in which the pillar fixing hardware 500 is installed upright. The pillar by the fixed connector 550 is fixed to the connecting groove 510 of the column fixed steel 500 through the pillar reinforcing member 300 through the perforated groove 260 formed in the pillar member 200. The member 200 is fixedly installed.

At this time, the pillar fixing iron 500 may be installed with a headstone 600, it is preferable that the insertion hole 610 is inserted into the pillar fixing steel 500 is formed.

That is, when the pillar fixing element 500 is inserted into the insertion hole 610 to install the headstone 600, the upper side of the pillar fixing element 500 at the portion where the connection groove 510 is formed is Exposed to the top of the headstone 600, in this state by installing the pillar member 200 to the column fixing hardware 500 exposed to the top of the headstone 600 to achieve a firm fixed installation of the pillar member (200) It becomes possible.

This is to prevent the occurrence of cracks in the wooden pillar by the coupling between the column fixed hardware and the pillar member between the hardware, and to prevent the expansion even if the crack is generated to increase its durability.

The hollow pillar reinforcing member 300 of the steel is installed to be inserted into the reinforcement groove 230 formed in the longitudinal direction in the center of the pillar member 200, but protrudes in the outward direction of the pillar member 200 on the upper side. The withdrawal bracket 310 is formed.

At this time, the column reinforcing member 300 is preferably to use a hollow circular pipe, which is when the construction of a wooden building having a variety of shapes (square, hexagon, octagon, etc.) of the beam member coupled to the pillar member used The column reinforcement member 300 is hollow because the number and angle of the drawing bracket 310 are varied due to the variety of lengths and processing positions of the column members suitable for the number of floors such as single layer, two layers, and three layers. It is to improve durability by maintaining the welding angle of the plate evenly under various conditions using a circular pipe.

In addition, when the column reinforcing member 300 of the circular pipe is inserted into the reinforcing groove 230, a space between the outer circumferential edge of the column reinforcing member 300 and the inner circumference of the reinforcing groove 230 is generated. In the present invention, by filling the resin-based resin 320 in the separation space is made to improve the thermal insulation of the pillar member 200.

In addition, when the condensation occurs due to the temperature difference between the pillar reinforcing member 300 and the pillar member 200 of steel as the resin 320 is filled in the separation space, the condensation does not directly contact the pillar member of the wood It is possible to prevent the corruption of the pillar member 200.

In addition, when the beam member needs to be additionally fitted on the site due to the structure of the product, the work of picking out the groove into which the beam member is fitted using a wood tool is performed, wherein the pillar reinforcement member is fitted to the inner circumference of the pillar member. If it is in contact with the work is very difficult, there is a problem that the column reinforcing member is damaged by the work tool in the process of fitting the beam member in the present invention is filled with a resin in the separation space to form a buffer space and dangerous when picking grooves The depth is to be recognized by the worker through the exposure of the resin to prevent such problems in advance.

Meanwhile, the resin-based resin 320 may be filled in the space between the outer circumferential edge of the pillar reinforcing member 300 and the inner circumferential edge of the reinforcing groove 230, but the present invention is not limited thereto. For example, wood powder, sand, finely shredded pieces of plastics, small pieces of urethane or rubber chips, etc. may be blended with a compounding material and resin to fill the space.

The beam member 400 is connected to the pillar member 200, but the tension member insertion hole 410 is formed in the longitudinal direction, both ends are tensioned with the prestress tension member 411 is installed in the tension member insertion hole 410 It is tension-fixed by the fixing member 420, and has a structure in which the drawing bracket 310 is connected to the tensile fixing member 420.

At this time, the beam member 400 may be formed so that a plurality of lamina (lamina) is laminated to each other so that the tension member insertion hole 410 is formed in the longitudinal direction between the lamina member.

Here, the tension member insertion hole 410 may be formed to be located in the lower direction relative to the center line in the width direction on the cross section of the beam member 400. That is, the lower end of the width direction in the state in which the beam member 400 is installed between the pillar member 200 is sagging phenomenon occurs, the tension member insertion hole 410 is installed the prestressed tension material 411 By positioning the beam member in the lower direction with respect to the imaginary center line on the cross section of the beam member, the lower end of the beam member in the width direction can be effectively prevented from sagging and can improve the durability of the beam member.

In addition, when the prestressed tension member 411 is installed inside the tension member insertion hole 410, a space is generated between the outer circumference of the prestressed tension member 411 and the tension member insertion hole 410, which is spaced apart. The filling member 412 is formed by filling an inelastic synthetic resin such as a resin in a space to integrate the beam member 400 and the prestress tension member 411.

This is because the prestressed tension member 411 is integrated into the beam member 400 by the filling layer 412 in a state in which the tension member 411 is inserted into the tension member insertion hole 410 of the beam member 400. This is to prevent the prestressed tension member 411 from exerting resistance as much as the spaced space when the bending phenomenon occurs.

At this time, the beam member 400 is formed in the width direction of the beam member is formed a plurality of filling holes 413 connected to the tension member insertion hole 410, the inelastic flow introduced through the filling hole 413 Resin-based resin is filled in the space between the outer periphery of the prestressed tension member 411 and the inner periphery of the tension member insertion hole 410.

The filling hole 413 is processed from the upper direction of the beam member 400 to the lower direction is preferably formed to be connected to the tension member insertion hole 410, which is the upper portion of the beam member 400 is compressive force It is because it is a part that does not affect the bending strength.

On the other hand, the tension fixing member 420 is installed at both ends of the longitudinal direction of the beam member 400 to maintain the tensile strength of the prestressed tension member 411 is tensioned while maintaining the tensile strength of the beam member 400 It is installed to be fixed between the members (200).

The tension fixing member 420 accommodates the end of the prestressed tension member 411 in a state in which the tension fixing member 420 is installed to be in close contact with both ends of the longitudinal direction of the beam member 400, and the fixed pressure plate 430 to which the drawing bracket 310 is connected. And a tension member fixing socket 440 for tension-fixing the prestress tension member 411 located inside the fixed pressure plate 430.

The fixed pressure plate 430 is in close contact with the lower side of the beam member 400 on the basis of the width direction center line in the cross section, the predetermined area formed with a through hole 432 to allow the end of the prestressed tension member 411 to pass through. It is formed to be bent in the direction of the pillar member 200 at the left and right ends of the contact face 431 and the contact face 431 in the state having the same or less height than the vertical height of the beam member 400 and the upper side The side surface 435 is cut to have a gentle inclined surface 438 in the upper direction of the contact surface 431 at the end, and the drawing bracket 310 is connected.

The contact face 431 is a plate of a predetermined area that is installed to be in close contact with the end surface of the aggregate wood in the lower direction on the basis of the virtual center line on the cross section of the beam member 400, the contact face 431 is the beam member While being in close contact with the 400, the end of the prestressed tension member 411 is drawn through the through hole 432 of the contact surface 431.

The side face 435 has a connecting end portion 436 formed to have the same height as the contact face 431 and the longitudinal end of the beam member 400 in an integrated state on the upper side of the connecting face portion 436. The side surface 437 is formed with the inclined surface 438 at the side end facing.

Here, the contact surface 431 is in close contact with the cross section in the downward direction with respect to the virtual center line S on the cross section of the beam member 400, and the inclined surface 438 by cutting a part of the side portion 437. If you look at the reasons for the formation,

As shown in FIG. 7A, the prestressing tension member 411 is tensioned when the close face 431 is formed to have the same area as the entire area of one end surface of the beam member 400 and is in close contact with the end face of the beam member. When tensioned and fixed through the fixing socket 440, the compressive force is transmitted to the entire upper (H) and the lower (L) based on the upper and lower parts of the beam member, that is, the virtual center line (S) by the contact surface 431, This acts as a factor that reduces the performance of the beam when the compressive force is transmitted to the upper portion of the center of the beam member that the compressive force acts to be used as the beam member of the structure.

Therefore, in the present invention, as shown in FIG. 7B, the contact surface 431 is formed to have an area in close contact with only the lower portion L of the beam member, and the side portion 437 facing the beam member 400 is formed. Compression force generated during tensioning of the prestressed tension member 411 is cut only in the lower portion L of the beam member by cutting a portion of the side portion so that the side end portion does not contact the end face of the beam member 400 to form the inclined surface 438. It is to be delivered.

In addition, the withdrawal bracket 310 of the column reinforcing member 300 is drawn between the side surface body 435 of the fixed pressure plate 430 is installed to be fixed by the through fixing pin 439, the extraction bracket 310 ) And the side surface body 435 is provided with a fixing pin installation hole 433 for the through-installation of the through fixing pin (439). At this time, the through-fixing pin 439 is a bar that can be used as a conventional bolt.

In the present invention, when connecting the pillar member 200 and the beam member 400 as described above, through the coupling between the take-out bracket 310 of the steel and the fixed pressure plate 430 of the steel can contribute to improving the stability of the wooden structure Is done.

That is, as shown in FIG. 8, when the withdrawal bracket 310 is inserted into the cross section of the beam member and an external force such as an earthquake or typhoon occurs in a state fixed by a separate through pin or bolt, the length of the beam member Cracking occurs in the direction to increase the risk of collapse of the wooden structure bar, in the present invention, the coupling between the iron is fixed to the withdrawal bracket 310 of the steel via the fixing pin 439 to the fixed pressure plate of the steel Preventing the occurrence of cracks in the beam member, as well as the upper load is transmitted through the hardware to the column and the ground, so that the stable state of the wooden structure can be maintained for a long time.

In particular, the wooden structure is a structure that loads a lot of load on the roof, the role of the beam member is very important, because the load of much more roof structure than the general structure must be transmitted to the column safely.

Therefore, the beam member that supports the roof structure and transmits the load to the pillar member has more flexural strength and flexural modulus than other members positioned on the upper beam member. It should be much harder.

In other words, the high flexural strength is required to safely respond to impact loads caused by natural disasters such as earthquakes or typhoons, and the high flexural modulus is required to reduce deflection even on roof loads. You will be able to respond more safely.

As described above, in the present invention, the pillar member and the beam member may be connected to each other through the pull out bracket 310 of the steel and the fixed pressure plate 430 of the steel, so that the coupling between the beam member and the pillar member may be stably coped with an impact load such as an earthquake. Since the prestressed tension member 411 is installed on the beam member 400 so that the lower portion of the beam member is broken, the prestressed tension member is not broken first, thereby delaying the collapse of the structure by securing a time allowance to improve the evacuation time of the user. You can earn.

In addition, the tension member fixing socket 440 is fixed to both ends of the prestress tension member 411 located inside the fixed pressure plate 430, in a state in which the prestress tension member is tensioned to have a constant tensile strength by a tension device. It is fixed by the tension member fixing socket 440 to maintain the tension state of the prestress tension member 411 for a long time.

In addition, the cover member 450 and the cover timber portion extending from the longitudinal end of the beam member 400 to extend to cover the side surface 435 of the fixed pressure plate 430 at a predetermined interval from each other ( Extended wood portion 460 is formed integrally extending between the side surface 435 of the fixed pressure plate 430 in a state located between the 450.

At this time, the extending wood portion 460 is formed to extend between the side surface 435 of the fixed pressure plate 430 in the cross section of the upper portion H on the basis of the width direction center line on the cross section of the beam member 400, The cover wood portion 450 extends in the direction of the pillar member from the side of the beam member in the state having the same height as the vertical height of the beam member 400 or less than the beam member 400, the extension wood It extends to the same extension length as the portion 460 to cover the side surface 435 of the fixed pressure plate 430.

Here, the cover wood portion 450 and the extension wood portion 460 is formed with a through hole 470 for the penetration of the through fixing pin 439, the through hole 470 is the fixing pin installation hole 433 It is formed at a position corresponding to.

In addition, as shown in Figure 13, when the upright installation of the pillar member 200 according to the present invention, one side of the pillar reinforcing member 300 is installed to be fixed to the concrete pouring portion embedded in the ground, the other side is the ground side The exposed pillar reinforcement member is coupled to be fitted to the pillar member 200 so as to be exposed, so that the pillar member 200 may be installed upright, by utilizing the pillar member and the beam member according to the present invention. It should be noted that it can be applied to the foundation structure.

On the other hand, the construction method of the seismic reinforcement type wooden building in which the prestressed tension material is introduced according to the present invention is a pillar member manufacturing step (S10) for manufacturing a pillar member, and to install the column reinforcement member 300 on the pillar member 200.
