Description

Wall type piloti structure of apartment buildings without load transfer

In the present invention, the front and rear walls are divided and spaced apart, but by placing the transverse piloti wall of the piloti layer directly under the divided transverse outer wall of the upper structure, the load of the upper structure is directly transferred to the piloti wall without a load transfer member. It is about a wall-type piloti structure of an apartment house without load transfer, which has excellent constructability by transferring and shortening the construction period and improving economic efficiency.

When constructing an apartment house, the upper part adopts a wall-type structure, which is a general apartment structure style, but in the lower floor, a structure composed of ramen-like is widely used to secure a sense of openness.

In this case, a transfer girder with a thickness of 2m or more is installed on the upper part of the lower piloti layer for load transfer in the part that changes from the wall structure to the ramen structure.

However, since these transition beams are very large, it takes a lot of time to reinforce reinforcement, install formwork, and place concrete. This delays the entire construction period and increases the amount of materials required, which is uneconomical.

In addition, since the flow of stress changes rapidly in the transition beam, there is a problem that the amount of reinforcement reinforcement is excessive due to stress concentration in most areas of the transition beam. In addition, since the vertical member is integrally connected and constrained under the transition beam having high rigidity, excessive stress concentration also occurs in the vertical member, thereby increasing the amount of reinforcement.

In addition, if a large load is applied to the transition beam, it is inevitable to deform the transition beam. In this case, there is a risk of defects such as the rise of the window epoxy due to the relative displacement in the vertical direction on the balcony of the upper floor of the transition beam.

In addition, apartment houses are generally constructed using large-sized foams such as gang foam. However, since the conventional piloti structure is composed of a ramen structure as described above, large-sized foams cannot be used, which is inefficient.

In order to solve the various problems of the transfer beam construction as described above, in Patent No. 10-1643584, a technique of removing the existing transfer beam and configuring the entire upper wall of the piloti layer as a transfer member has been proposed (FIG. 1).

However, even in the case of the above registration technology, load transfer occurs in the upper wall of the piloti, causing excessive stress concentration in the wall, and since the piloti column is connected to the transition wall with strong rigidity, stress concentration occurs in the piloti column as well, resulting in excessive reinforcement. I have no choice but to.

In addition, a thin wall serves as a transition beam, and since there is no transverse support member in the middle, the rigidity in the weak axis direction is weak, so that the transition member cannot properly function as a transition member.

In order to solve the above problems, the present invention is to provide a wall-type piloti structure in an apartment house without load transfer, which can remove the load transfer member itself and transfer the load of the upper structure directly to the piloti wall.

Accordingly, an object of the present invention is to provide a wall-type piloti structure in an apartment house without load transfer, which can achieve the effect of shortening the construction period and reducing the construction cost by easily and easily constructing the piloti layer.

The present invention according to a preferred embodiment of the present invention is a plurality of apartment houses which are arranged to be spaced apart from each other on the outer periphery of the front and rear surfaces of the unit household layer in an apartment building having an upper structure formed by vertically stacking at least one unit household layer on an upper part of the piloti layer The transverse outer wall of the; A transverse piloti wall formed to extend to the piloti layer under the transverse outer wall to support the transverse outer wall and to have a width narrower than that of the transverse outer wall; And a railing wall protruding from the upper part of the slab and a water wall protruding from the lower part of the slab by being provided between the transverse external walls on the upper part of the piloti layer to connect the neighboring lateral external walls. , A horizontal connection wall in which a plurality of main muscles disposed in a horizontal direction and stirrup surrounding the plurality of main muscles are disposed; And a plurality of vertical walls are arranged in parallel in the same column as the horizontal outer wall in the same row as the horizontal outer wall, and are formed to extend to the bottom of the vertical wall to support the vertical wall. It provides an apartment house wall type piloti structure without load transfer, characterized in that directional piloti walls are arranged.

The present invention according to another preferred embodiment is the upper and lower portions of the boundary between the transverse outer wall and the transverse piloti wall, respectively, parallel to the axis of the transverse outer wall and the transverse piloti wall, and an inclined offset reinforcing bar is reinforced at the center. It provides a wall-type piloti structure of an apartment house without load transfer, characterized in that it is.

According to the present invention as described above has the following effects.

First, in an apartment building where the type of upper and lower structures is changed, the walls of the front and rear surfaces are divided and arranged to be spaced apart, but the transverse piloti wall of the piloti layer can be placed directly under the divided transverse outer wall of the upper structure. As a result, the load of the upper structure can be directly transmitted to the vertical members of the piloti layer, so there is no need to install a transition member that is cumbersome and takes a long time to construct, and the load transmission path is simple, so design and construction are easy, and construction time is shortened. Do.

Second, since the vertical load is naturally transmitted to the lower piloti layer without load transfer, there is almost no relative vertical displacement on the balcony side, thus minimizing the occurrence of defects.

Third, since the transverse piloti wall disposed on the outer periphery of the piloti layer is continuous with the transverse outer wall of the upper structure, it is very economical because a large-sized foam can be used early.

Hereinafter, the present invention will be described in detail according to the accompanying drawings and preferred embodiments.

FIG. 2 is a perspective view showing a wall-type piloti structure of an apartment house without load transfer of the present invention, FIG. 3 is a plan view showing a piloti layer, and FIG. 4 is a plan view showing an upper layer of the piloti layer. And Figure 5 is an elevational view showing the flow of the vertical load when the present invention is applied.

As shown in Figures 2 to 4, the present invention, the wall-type piloti structure of an apartment house without load transfer is a superstructure (3) formed by vertically stacking at least one unit household layer (30) on top of the piloti layer (2) In the apartment building (1) provided, a plurality of transverse outer walls (31) arranged to be spaced apart from each other on the outer periphery of the front and rear surfaces of the unit household floor (30); And a transverse piloti wall 21 extending to the piloti layer 2 below the transverse outer wall 31 to support the transverse outer wall 31; It characterized in that it consists of.

In the present invention, by removing the load transfer member located in the part where the shape of the upper and lower structures is changed, and allowing the load of the upper structure 3 to be directly transferred to the piloti wall, it is possible to facilitate the construction of the piloti layer 2 and shorten the construction period. It is to provide a wall-type piloti structure in an apartment house without load transfer.

In the present invention, the apartment building (1) is composed of the piloti layer (2) at the bottom and the upper structure (3), and the upper structure (3) is a plurality of unit household layers (30) are stacked in a vertical direction. It is composed.

A plurality of transverse outer walls 31 are disposed on the outer peripheries of the front and rear surfaces of the unit household layer 30 so as to be spaced apart from each other.

Here, the transverse direction means the transverse direction in the drawing. In addition, the longitudinal direction refers to the longitudinal direction in the drawing, that is, the direction through which the pilotie layer 2 penetrates.

A transverse piloti wall 21 extending below the transverse outer wall 31 and supporting the transverse outer wall 31 is disposed on the pilotie layer 2.

As described above, in the present invention, the walls of the front and rear surfaces of the apartment building 1 are divided and spaced apart, and the transverse piloti wall 21 is disposed directly under the divided transverse outer walls 31.

Accordingly, the load of the upper structure 3 is not transferred to the vertical member of the piloti layer 2 by transferring the load by the transfer member, but the load of the vertical member of the upper structure 3 is directly transmitted to the vertical member of the piloti layer 2 do.

Therefore, since there is no load transfer, it is cumbersome to construct and there is no need to install a transfer member that takes a long time, and the load transfer path is simple, so design and construction are easy.

In addition, since the vertical load is naturally transmitted to the lower piloti layer 2 without load transfer, there is almost no relative vertical displacement on the balcony side, so that the occurrence of defects can be minimized.

In addition, since the transverse piloti wall 21 disposed on the outer periphery of the lower piloti layer 2 is continuous with the transverse outer wall 31 of the upper structure 3, it is very economical because a large foam can be used early.

Inside the unit household layer 30, a plurality of vertical walls 32 are arranged in parallel in the same row as the horizontal outer wall 31 in the same column, and extend to the bottom of the vertical wall 32. Thus, the longitudinal piloti wall 22 supporting the longitudinal wall 32 may be disposed.

The piloti structure is installed to ensure the maximum openness, and should be configured so that the view is not obscured by the vertical member inside the piloti layer (2).

Therefore, in the plane of the unit household layer 30, the longitudinal walls 32 are disposed in the same row as the transverse outer walls 31, while the bearing walls are disposed in parallel in the longitudinal direction. And the piloti layer 2 supporting this is also configured to form the piloti wall 22 in the longitudinal direction so as to be continuous with the longitudinal wall 32, so that the front and rear surfaces are opened to form the pilotie layer 2 that can maximize the openness. .

In this way, if the walls are arranged in parallel in one direction in the unit household layer 30 of the upper structure 3, construction is very easy, plane variability is excellent, and the amount of reinforcement can be reduced by reinforcing the slab as a one-way slab. .

In the present invention, unlike the conventional piloti structure in which the upper and lower structures are separated by transition beams, the planar shape of the unit generation layer 30 of the upper structure 3 is determined in consideration of the arrangement of the piloti layer 2 located at the lower side. . In addition, by expanding this to the lower piloti layer 2, the upper structure 3 as well as the lower piloti layer 2 are structurally very efficient and easy to construct.

As shown in FIGS. 2 and 9, a horizontal connection wall comprising a slab 33 and a railing wall 341 protruding upward between the transverse outer wall 31 on the upper part of the piloti layer 2 ( 34) can be connected.

The transverse connection wall 34 transmits the load of the transverse outer walls 31 that are separated from each other and spaced apart from each other with respect to the transverse load to the slab 33 serving as a diaphragm.

The horizontal connection wall 34 supports the lateral outer wall 31, and the slab 33 supports the lateral force of the horizontal connection wall 34 (FIG. 5).

In addition, the horizontal connection wall 34 distributes the stress concentration generated at the junction between the transverse outer wall 31 and the transverse piloti wall 21.

In this case, the horizontal connection wall 34 may utilize a railing wall 341.

The existing balcony railing wall was not a structural material that bears a load, but in the present invention, by using the railing wall 341 as a structural material, it is possible to naturally induce the flow of the load without concentration of stress.

6 to 8 show structural program analysis results for the conventional transfer beam type and the present invention load transfer-free apartment house wall piloti structure type.

First, FIGS. 6A and 6B are diagrams showing vertical displacements for gravity loads in the conventional transition beam type and the wall pilotti structure type of the present invention, respectively.

As shown in (a) of FIG. 6, in the conventional transition beam type, it can be seen that a large relative vertical displacement occurs on the front and rear balconies of the upper piloti generation.

As shown in (b) of FIG. 6, when the present invention is applied, it can be seen that the relative vertical displacement of the front and rear balcony side of the upper piloti generation rarely occurs.

7A and 7B are diagrams showing stress concentration aspects of the conventional transition beam and the horizontal connecting wall of the wall piloti structure of the present invention, respectively.

As shown in (a) of FIG. 7, in the conventional transition beam type, it can be seen that the stress concentration phenomenon occurs in most regions of the transition beam.

On the other hand, as shown in (b) of FIG. 7, when the present invention is applied, the stress concentration phenomenon occurring in the horizontal connection wall 34 is insignificant.

8A and 8B are diagrams showing stress concentration patterns of the front and rear walls of the balcony in the conventional transition beam type and the wall piloti structure type of the present invention, respectively.

As shown in (a) of FIG. 8, in the conventional transition beam type, it can be seen that the stress concentration phenomenon occurs in the wall fixed to the transition beam.

In contrast, as shown in (b) of FIG. 8, when the present invention was applied, the stress concentration phenomenon did not occur in the transverse piloti wall 21.

9 is a cross-sectional view showing a state of reinforcement of a horizontal connecting wall.

As shown in FIG. 9, the horizontal connection wall 34 may be formed to extend integrally under the railing wall 341 to include a water wall 342 protruding below the slab 33.

The water wall 342 extending below the slab 33 can be utilized as a structure.

By forming the water wall 342, the width of the horizontal connecting wall 34 that transmits the lateral force of the vertical member to the slab 33 and distributes the stress can be secured as much as possible. And since the slab 33 serving as a diaphragm can be positioned in the center of the horizontal connection wall 34, the stress of the horizontal connection wall 34 is stably transmitted to the slab 33 without eccentricity, and the horizontal connection wall ( It can prevent buckling by increasing the stiffness in the weak axis direction of 34).

Inside the horizontal connection wall 34, a plurality of main muscles 343 disposed in a horizontal direction and a stirrup 344 surrounding the plurality of main muscles 343 may be arranged.

In the general railing wall 341, vertical reinforcing bars are the main bars. In other words, the reinforcement is laid as the wall reinforcement.

However, in the present invention, the horizontal connecting wall 34 including the railing wall 341 transmits the lateral force of the lateral outer wall 31 to the slab 33, and the horizontal reinforcing bar is the main bar 343 to disperse the wall joint stress. Reinforcement is laid with the beam reinforcement.

Since the railing wall 341 needs to transmit a shearing force, a stirrup 344 surrounding a plurality of main muscles 343 may be placed inside the horizontal connection wall 34.

The horizontal connection wall 34 composed of the railing wall 341 and the water wall 342 extending below the railing wall 341 is elongated, so that when a compressive load is applied, lateral buckling may occur in an out-of-plane direction.

Therefore, in this case, a transverse support reinforcing bar 345 structurally uniting the slab 33 and the transverse connecting wall 34 so that the slab 33 supports the middle of the transverse connecting wall 34 to prevent transverse buckling. It can be placed in the junction of the slab and the horizontal connection wall (34).

In addition, as shown in FIG. 9, a crack prevention reinforcing bar 346 for preventing cracks in the horizontal connection wall 34 having a high height may be additionally reinforced.

Fig. 10 is a cross-sectional view showing a state of reinforcement of a boundary between an outer wall in a transverse direction and a piloti wall in a transverse direction.

As shown in FIG. 5 and the like, the width of the transverse piloti wall 21 may be formed to be narrower than the width of the transverse outer wall 31.

In general, wall-type apartment houses are designed so that the bearing wall also serves as a space division, so there are many wall parts. Accordingly, the actual wall weight is designed to exceed the number of walls required to support the vertical load of the building.

Therefore, it is not necessary to extend the entire outer wall 31 in the transverse direction to the pilotie layer 2 below the piloti layer 2, which must have the maximum open area.

Accordingly, the transverse outer wall 31 is partially extended to the lower portion to form the transverse piloti wall 21 to maximize the open area of the pilotie layer 2.

Of course, if necessary, such as when the load acting on the transverse piloti wall 21 is large as a result of the structural analysis, it is possible to increase the thickness of the transverse piloti wall 21 or use high-strength concrete.

On the other hand, since the area of the piloti wall 22 in the longitudinal direction is irrelevant to the front open area of the piloti layer 2, it is not necessary to narrow the width of the wall.

As shown in FIG. 10, at the boundary between the transverse outer wall 31 and the transverse piloti wall 21, the axes of the transverse outer wall 31 and the transverse piloti wall 21 at the upper and lower portions, respectively. An offset reinforcing bar 23 that is parallel to and inclined at the center may be reinforced.

In the present invention, since the vertical member load of the upper structure (3) is directly transmitted to the vertical member of the piloti layer (2), the vertical reinforcement is overlapped at the boundary between the transverse outer wall (31) and the transverse piloti wall (21). shall.

However, when the width of the upper and lower vertical walls is changed, it is difficult to directly overlap and connect the vertical reinforcing bars of the upper and lower vertical walls.

Therefore, by installing an offset reinforcing bar 23 at the boundary between the transverse outer wall 31 and the transverse piloti wall 21, it is possible to induce the flow of force to occur smoothly.

In addition, in order for the reinforcing bar to smoothly transmit the stress at the bent portion of the offset reinforcing bar 23, a horizontal support force is required. For this purpose, it is preferable to use a transverse reinforcing bar such as a band reinforcing bar or a spiral reinforcing bar to support the horizontal force at the bend portion of the offset reinforcing bar (23).

The offset reinforcing bar 23 is preferably configured to have a gentle slope of 1/6 or less so that vertical stress can be effectively transmitted.
