Description

Rahmen-type PC ramp for parking lot

The present invention installs a PC girder on a PC column in the same row and combines the PC slab on the upper side of the PC girder on both sides to form a ramen-type PC parking lot ramp with a modular PC structure consisting of a PC column, a PC girder and a PC slab. It is about a ramen-type PC parking lot ramp that can secure structural stability and economic feasibility.

In apartment houses, etc., the size of the underground parking lot is getting bigger due to the increase in the number of vehicles per household and the underground parking space.

Accordingly, recently, there are many cases of underground parking lot construction using the PC method.

In particular, due to the implementation of the 52-hour workweek system, there is a growing concern about labor costs and delays in delivery, and the increase in the implementation of the 85th system of the 8 o'clock shipment of ready-mixed concrete and the 5 o'clock closing of the ready-mixed concrete is increasing the supply and demand problem of on-site ready-mixed concrete. there is a trend

Since the underground parking lot has a large area of the parking lot itself, a standardized plane can be applied, so it is easy to modularize the members, and the connection between the members is relatively simple, so it is suitable for applying the PC method.

However, the ramp section for entering the parking lot is not easy to modularize, so it is still often constructed using the RC method.

Accordingly, the ramp section acts as a delay factor in the construction of the parking lot due to the application of the RC method, although the proportion of the area occupied by the entire parking lot is very small. In addition, there is a problem in that it is impossible to enter the vehicle until the completion of the lamp construction, which causes difficulties in the subsequent construction.

An object of the present invention is to provide a ramen-type PC parking lot ramp that can improve economic efficiency while securing constructability and structural stability by configuring the parking lot ramp section in a modularized PC structure.

The present invention Ramen-type PC parking lot ramp is configured to include a PC column (1), a PC girder (2) and a PC slab (3), and the PC girder (2) is installed on the PC column (1) in the same row, and the It is constructed by installing a PC slab (3) on the PC girder (2).

That is, the parking lot ramp is composed of a ramenjo that supports the load by columns and beams.

The PC pillars 1 are arranged in two rows so that a plurality of them are spaced apart from each other on both sides of the parking lot ramp.

As shown in Figure 6, the PC pillar (1) is a first bracket (11) formed to protrude at a height corresponding to the inclination angle of the lower floor ramp at the top of the first pillar (11) 12), the second pillar portion 13 provided on the upper portion of the first bracket 12, and the second bracket 14 protruding at a height corresponding to the inclination angle of the lamp of the upper layer at the top of the second pillar portion 13 is composed of

The present invention is a modularization of a parking lot ramp of two or more floors by the PC method, and the PC pole (1) is composed of a first column part 11 supporting the lower floor lamp and a second column part 13 supporting the upper floor lamp do.

Brackets 12 and 14 for mounting the PC girder 2 are protrudingly formed on the upper portions of the respective pillars 11 and 13 .

Here, the brackets 12 and 14 are meant to include the first bracket 12 and the second bracket 14 .

The height of the brackets 12 and 14 of each of the pillars 11 and 13 is determined to correspond to the inclination angle of the ramp.

The inclination of the ramp can be designed by standardizing it to 8.5°.

Even if the height of the brackets 12 and 14 is changed according to the position of the PC pole 1, only the length of the first pole part 11 is changed and the rest of the PC poles 1 are all the same. By this, the entire PC pillar 1 can be produced.

That is, by changing the position of the copper plate in the same mold to adjust the length of the first pillar portion 11, it is possible to manufacture all the PC pillars (1).

The first pillar 11 of the PC pillar 1 needs to support both the load of the upper layer and the lower layer, while the second pillar 13 only needs to support the load of the upper layer.

Therefore, as shown in (a) and (b) of Figure 7, the thickness of the second pillar portion 13 is preferably formed to be thinner than the thickness of the first pillar portion (11).

4 and the like, the PC girder 2 is mounted on the brackets 12 and 14 of the PC pillar 1 adjacent in the longitudinal direction of the ramp.

That is, the PC girder 2 is mounted on the first bracket 12 adjacent in the longitudinal direction of the ramp.

In addition, the PC girder 2 is mounted on the second bracket 14 adjacent in the longitudinal direction of the ramp.

The PC girder 2 is installed only in the longitudinal direction of the ramp, that is, the PC posts 1 in the same row, and is not installed in the width direction of the ramp.

Therefore, the brackets 12 and 14 are formed to protrude left and right of the PC pole 1 so that the PC girder 2 can be mounted on both sides of the PC pole 1 .

In the present invention, the PC girder (2) is mounted only on the left and right sides of the PC column (1) to support the load in only one direction. Therefore, the second pillar portion 13 may be formed in a rectangular cross-section having a long length in the longitudinal direction of the lamp.

At this time, in order to secure the space inside the lamp, it is preferable that the second pillar part 13 is eccentrically disposed so as to be located outside the first pillar part 11 in plan view. That is, the outer surface of the second column part 13 may be configured to coincide with the outer surface of the first column part 11 .

When the second pillar portion 13 is formed in a rectangular cross section, it is possible to secure the maximum width of the ramp.

As described above, in the present invention, by forming the parking ramp section as an independent ramen group supporting the load with the PC pillar (1) and the PC girder (2), it can be independently constructed without being affected by the surrounding structural form.

As shown in FIG. 5 and the like, the PC slab 3 is mounted on the upper portion of the PC girder 2 adjacent in the width direction of the ramp.

The PC slab 3 preferably uses a half PC for pouring the on-site concrete 4 on the upper part after installation in consideration of the unification of the joint and the load burden (FIG. 2, etc.).

Unrooted concrete 5 for finishing may be poured on the upper part of the on-site concrete 4 ( FIGS. 10 and 11 ).

As shown in FIG. 8 , the PC slab 3 may be configured such that a plurality of rows of reinforcing ribs 32 protrude from the lower portion of the panel part 31 so as to secure rigidity while making the weight light.

When pouring the on-site concrete 4 on the upper part of the PC slab 3, the panel part 31 bends the end of the panel part 31 into an L-shape so that the concrete does not flow out through the opening due to the reinforcing rib 32. ) can be mounted directly on the upper side of the PC girder (2).

In this case, since there is no reinforcing rib 32 at the lower end of the end of the PC slab 3 mounted on the PC girder 2 , the upper rib 33 may protrude from the upper portion of the panel unit 31 .

The upper rib 33 not only reinforces the end of the panel part 31, but also contributes to member integration by being fixed in the on-site concrete 4 to be cast on site.

The PC slab 3 is composed of a one-way slab supported only by the PC girders 2 on both sides without a separate small beam. Therefore, it is possible to secure excellent economic efficiency as well as shorten the construction period.

As described above, in the present invention, the PC column (1), the PC girder (2) and the PC slab (3) can all be standardized to a minimum type, so that productivity and economic efficiency can be improved.

On both sides of the PC parking lot ramp, it is possible to install masonry walls 6 for fire protection between the surrounding frame and the surrounding frame (FIG. 2).

Fig. 9 is a perspective view showing an embodiment of a PC girder.

As shown in Figure 9, the PC girder 2 has both ends to the upper outer side of the bottom plate portion 21 and the bottom plate portion 21 that are mounted on the upper brackets 12, 14 of the PC column (1). It may be formed in an L-shaped cross-section composed of a protruding anti-collision protrusion 22 .

The PC girder (2) may be integrally formed with an anti-collision sill 22 for preventing the vehicle passing the ramp from colliding with the surrounding frame wall.

To this end, the PC girder 2 can be formed in an L-shaped cross-section consisting of the bottom plate part 21 at the lower part and the collision avoidance protrusion 22 at the upper part.

When the PC girder 2 is formed in an L-shaped cross-section, the PC girder 2 may serve not only as an anti-collision role, but also as a harness formwork when pouring the on-site concrete 4 .

Preferably, the width of the bottom plate portion 21 is the same as the width of the first bracket 12 or the width of the second bracket 14 .

It is preferable that the collision avoidance protrusion 22 is configured so that there is no protrusion inside the ramp by forming the second pillar part 13 to have the same thickness.

An extension 16 having the same cross section as the collision avoidance sill 22 of the PC girder 2 may be formed on the upper portion of the second bracket 14 .

As shown in FIG. 6 , the brackets 12 and 14 are formed with the same height as the bottom plate 21 of the PC girder 2 on the top of the brackets 12 and 14 , and the mounting part 15 on which the PC slab 3 is mounted is provided. A protrusion may be formed.

Since the PC girder 2 is mounted on both sides of the PC pillar 1 , an empty space is generated under the PC slab 3 in the front portion of the second pillar 13 . Therefore, a separate formwork is required for this part for pouring on-site concrete (4).

Accordingly, by forming the mounting portion 15 having the same height as the bottom plate portion 21 of the PC girder 2 on the upper portions of the brackets 12 and 14, the PC slab 3 may be seated.

The mounting portion 15 and the second pillar portion 13 may form an L-shaped cross-section to form the same plane as the PC girder 2 of the L-shaped cross-section.

The second pillar 13 forms an extension 16 that extends to the height of the collision avoidance sill 22 of the PC girder 2 mounted on the top of the second bracket 14, so that the neighboring PC girder ( 2) between the extensions 16 can be configured to serve as a collision avoidance sill 22 .

The brackets 12 and 14 can be formed to be inclined by about 8.5° to correspond to the inclination angle of the ramp. In the upper level ramp, the mounting part 15 and the extension part 16 support the PC girder 2 to support the PC girder (2). ) can be prevented from slipping and falling from the second bracket 14 .

An extension 16 having the same cross section as the collision avoidance sill 22 of the PC girder 2 may be formed on the upper portion of the second bracket 14 .

10 is a cross-sectional view showing a coupling relationship between a PC girder and a PC slab.

As shown in Figure 10, the coupler 23 is embedded in the inside of the collision avoidance sill 22, and the coupler 23 is fixed in the on-site concrete 4 that is poured on the top of the PC slab 3. Reinforcing bars 24 may be configured to be coupled.

The PC girder 2 is arranged only in the longitudinal direction of the ramp.

Therefore, the coupler 23 is embedded in the inner surface of the PC girder 2 so that the PC slab 3 can connect and support the PC columns 1 adjacent to each other in the transverse direction, and the anchoring reinforcing bar ( 24) can be combined to be fixed to the PC slab (3).

At this time, the anchoring reinforcing bar 24 should be fixed inside the on-site concrete (4) to be cast on-site on the PC slab (3). However, since the PC slab 3 is mounted on the upper portion of the bottom plate 21 of the PC girder 2, the coupler 23 is embedded in the position of the collision avoidance protrusion 22 of the PC girder 2 to the coupler 23. The anchoring reinforcing bars 24 to be combined are positioned at the level of the site concrete (4).

Accordingly, since the PC slab 3 is strongly bonded to the PC girder 2 at the end, the thickness of the PC slab 3 can be reduced.

It is sectional drawing which shows the coupling relationship of a PC girder and a bracket.

11, the anchoring steel rod 17 is anchored to the upper portion of the brackets 12 and 14, and the anchoring steel rod 17 is inserted into the through hole 25 formed in the PC girder 2 to insert the PC It can be configured to be fixed to the girder (2).

In order to fix the PC girder 2 to the brackets 12 and 14 of the PC column 1, a fixing steel bar 17 may be installed on the brackets 12 and 14 to be fixed.

The anchoring steel rod 17 may be installed in advance when the PC pole 1 is manufactured, or may be anchored to the upper portions of the brackets 12 and 14 in the field.

To this end, anchor holes are drilled in the upper portion of the brackets 12 and 14 to a predetermined depth to anchor the anchoring steel rod 17, or a separate coupler is pre-buried in the brackets 12 and 14, and then the anchoring steel rod 17 is inserted into the coupler. can be combined.

A through hole 25 is formed in the PC girder 2 in order to couple the anchoring steel rod 17 to each other.

After inserting the anchoring steel rod 17 into the through hole 25, by injecting epoxy or the like into the through hole 25 or fastening a nut to the upper portion of the anchoring steel rod 17 to fix the PC girder 2 into the bracket. It can be fixed at (12, 14).

When the PC girder 2 has an L-shaped cross section, a through hole 25 may be formed to pass through both the bottom plate portion 21 and the collision avoidance sill 22 to fix the fixing steel rod 17 .
