Description

Composite Structure with Long Span Cable Bridge and Building}

The present invention relates to a composite structure of a main tower and a high-rise building of a long bridge that is supported by a cable, and specifically, in a cable bridge such as a cable-stayed bridge and a suspension bridge installed to cross a river, a valley, or an ocean, the load of a cable and a top plate In the position where the pylons supporting the bridge, the pylons of the bridge and the frame structure of the building (building) relates to the composite structure of the bridge pylon and the building integrally formed.

A bridge is a structure whose main function is to connect traffic paths on the surface of rivers, rivers, seas, lakes, or across valleys. There are various types of bridges such as Ramen Bridge, Arch Bridge, Truss Bridge, Cable-Stayed Bridge, and Suspension Bridge, which are selected in consideration of the length of the bridge, the surrounding environment, the type of bridge passing load, and aesthetics. Construction of long bridges has been steadily increasing due to the development of materials and construction technology and economic level. In particular, the construction of ultra-long bridges with more than 1km of span and a total length of more than 10km has been increasing recently. These ultra-long bridges are constructed in the form of cable bridges that support the tops with cables, including suspension bridges and cable-stayed bridges.

Suspension bridges and cable-stayed bridges, with long spans and elegant curves or straight lines, are mostly tourist attractions as landmarks. Therefore, there is a great demand for such cable bridges in large cities along large rivers. However, the construction of long bridges with cable bridges, such as suspension bridges and cable-stayed bridges, is very costly to construct cable bridges because of the high construction costs. Therefore, in order to meet the social demand for high-cost long cable bridges, and to revitalize long cable bridges, it is necessary to reduce the construction cost of bridges and, on the other hand, to create added value beyond the simple connecting means of both roads. have.

On the other hand, since the cable bridge is a structure in which the main tower supports the vertical and horizontal loads acting on the bridge, the rigidity of the main tower is an important factor in determining the main span length of the bridge. The rigidity of the pylon is determined depending on the material used and the size of the cross section. Currently, most cable bridges have one pillar on each side of the bridge and two pillars on one side of the bridge. The suspension tower is composed of two main towers. In the case of a variety of towers from one main tower to three or more. In the case of the cable-stayed bridge, the cable located at the top serves as an anchor to hold the main tower bending in the direction of the bridge due to the uneven load.In the two main tower cable-stayed bridge with two main towers, the cable is anchored at both piers and left and right balanced. In the multi-main tower cable-stayed bridge with three or more pylons, the central pylon needs great rigidity because the center pylon needs to be anchored. In the case of the multi-column continuous cable-stayed bridge, the rigidity of the pylon is limited by the length of the bridge.

Therefore, there is an urgent need to provide technical means that greatly increase the stiffness of the pylon against the lateral (orthogonal and axial direction) loads, while sufficiently increasing the span while not causing unbalance in terms of safety, aesthetics, and economics.

On the other hand, in the case of suspension bridges, almost all bridges have the form of two-column suspension bridges. In the case of long extension of bridges, connecting bridges should be placed on both sides of suspension bridges or long main bridges should be made. In the former case (when the bridge is connected), it can be a factor of deteriorating the view of the bridge. In the latter case (when the main span is longer), the cross section of the main cable is very large due to the excessively long span. It can be disadvantageous in terms of economy and workability. As a solution to this problem, there is a three main tower suspension suspension having three main towers. As mentioned above, there is a burden of increasing the rigidity of the central main tower. Therefore, as a suspension tower of three main tower type, there is an urgent need to provide a technical means for constructing a suspension bridge without damaging the beautiful scenery of the suspension bridge with great rigidity.

On the other hand, currently used pylons are inverted Y-shaped (as viewed from the axial direction) of the cable-stayed bridge, which has a large rigidity against twisting and has an economical cross section. Pylons with four pillars, each of which appear to be inverted Y-shaped, are often used. Suspension bridges are often used with two-column pylons, in which two columns rise side by side. This is due to the characteristics of suspension bridges in which the main cable is mounted on the pylons. Pylons of the above shape have structurally important performance and economically advantageous shape, but when using the structure of the pylon on the cable bridge to have a residential space like a building, the shape of the pagoda is very disadvantageous due to its shape. do. First of all, it is difficult to install the residential space in the space directly above the upper plate where the pylon is located, and the binding force against horizontal displacement or distortion of the building disposed on both sides of the pylon is inferior. Therefore, when making a residential space using the pylons in the cable bridge, a new pylon structure should be provided in which the rigidity can be secured without restriction on space utilization.

On the other hand, in the case of high-rise building, due to the convenience of the internal space utilization and construction advantages, the frame structure is composed mostly of a combination of columns and girders. In the case of high-rise buildings having such a frame structure, it is very important to secure the rigidity against horizontal displacement and distortion due to the horizontal load because the rigidity is relatively small compared to the concrete wall structure. The stiffness to horizontal load is mainly dependent on the material and section size of the column member.The column member must bear the horizontal force along with the axial force, so in the case of high-rise buildings where the horizontal force is large, the cross section of the column member may increase or There must be a lot more. If the number of pillar members is too large, the advantages of free space utilization are lessened. On the contrary, the cross section of the pillar members becomes excessively large, which causes the pillar members to hinder aesthetics or reduce economic efficiency.

In particular, when the height of the pylon exceeds 100m, the building also has a corresponding height, it is necessary to provide a technical means for the high-rise building to have an economical cross section while retaining great rigidity with respect to the horizontal force.

On the other hand, in order for the building to be used as a residental space in contact with the main tower at the main tower location of the cable bridge, smooth entry and exit of the vehicle must be secured. In the case of the existing cable bridge, the main tower column located in the center of the cable section, that is, in the direction perpendicular to the bridge axis Since the cable is blocking the entrance and exit of the vehicle, a solution to this problem must be devised in order to place a building used as a residential space at the main tower location.

In addition, in the case of a long cable bridge, it is very important to perform routine maintenance such as periodic inspection due to its structural characteristics. However, since there is no resident space in the bridge and the access road is also poor, there are many limitations in daily maintenance.

On the other hand, there have been various attempts to utilize waterfront or water spaces as leisure and leisure spaces as the income level and the desire for a pleasant life increase. The installation of sports leisure facilities and water floating structures on the grounds is part of this attempt. However, it is not yet possible to construct buildings in water spaces and use them as residential spaces. Constructing a sedentary space such as a building in the water space can save expensive land costs, but also has the advantages of excellent view rights and direct entry and exit into the water space. Costly, especially in rivers in urban areas, there is a problem that the river function due to the erosion of the cross section during flooding is deteriorated, and a way to solve this problem should be sought.

The present invention was developed in order to overcome the problems and disadvantages of the prior art as described above, and to satisfy the above practical needs, specifically, the main structure of the bridge and the frame structure of the building integrally combined and structurally complement each other. The purpose of the present invention is to provide a new type of composite structure in which the main tower of the bridge and the building are integrated by forming a composite structure.

In addition, while increasing the rigidity of the pylons of the cable bridge, the cost increase due to the increase of the cross section is eliminated through the reduction of the structural members, and the aesthetic disadvantages caused by the enlarged cross section are resolved through the molding beauty of the composite structure and the exterior design of the building. It aims to do it.

In addition, the main column of the bridge to bear the horizontal load of the building and to act as a super column to actively suppress the horizontal displacement, so that the pillar member of the building to bear only the vertical load to enable economic design and construction of the pillar member The purpose. In addition, it aims to relieve anxiety and structural instability due to horizontal flow which is common in high-rise buildings.

In addition, by increasing the stiffness of the pylon pylon tower of the cable bridge, the main bridge to increase the main span in the case of the multi-column-type cable-stayed bridge, and to enable the suspension bridge of the three-pipe tower system.

In addition, the present invention increases the stiffness of the pylon to increase the span of the cable bridge to reduce the number of bridges to minimize the encroachment of the passage surface, thereby providing a structure that is less affected by fluctuations in the water level, such as flooding the river basin It aims to be able to make use of space as residence space.

It also aims to enhance the socio-economic value of bridges remaining in their function as simple connections by providing a means to actively utilize water spaces in the form of residential spaces by utilizing cable bridges. In addition, the present invention aims at activating the construction of a long cable bridge with excellent aesthetics and views in the urban area by improving the economic value of the long cable bridge.

In addition, the present invention provides a building (building) as a residential facility having an access road and a parking space that can directly enter and exit the building on the bridge to allow the multiple and smooth use of the residential facilities located in the bridge and water space For the purpose of

In addition, an object of the present invention is to enable the management personnel to reside in the building integral with the bridge to facilitate routine maintenance.

In the present invention, in order to achieve the above object, the pylon is composed of four pylon pillars and crossbeams connecting the pylon pillars in the axial direction and the right angle to the axial direction, the girder and the pillars on both sides of the pylon in the right angle direction. The frame structure of the building is located, and the main tower and the frame structure are integrally combined so that the main tower supports the bridge cable as a supercolumn and bears the horizontal force acting on the building and restrains the horizontal displacement and distortion of the building. The main structure of the cable bridge to perform and the composite structure of the building is provided.

In addition, the present invention provides a composite structure in which the enlarged cross-section of the pylon, which may be aesthetically disadvantageous while greatly increasing stiffness, is complemented by the molding beauty of the composite structure and the exterior design of the building.

In addition, in the present invention, based on the complex structure, the building for the settlement space in contact with the main tower in the direction perpendicular to the bridge axis is arranged on both sides of the main tower and has an access road that can directly enter and exit the vehicle from the bridge to the building, An active composite bridge tower and a building are provided.

According to the present invention, it is possible to enhance the social and economic value of the bridge by being able to take advantage of the water space by the sedentary space is arranged as a separate structure connected to the main tower integrally in contact with the main tower of the cable bridge constructed by the extension of the road As a result, it is possible to expect the effect of reducing the cost of the construction of the long cable bridge, and thus can build more long cable bridges with excellent views.

In addition, according to the present invention, by providing an access road and a parking space in the building that can smoothly enter and exit the bridge from the building to satisfy the desire for viewing rights by ensuring multiple access to the ultra-long bridge, thereby providing tourism You can expect additional income as a attraction.

In addition, according to the present invention, since the cable bridge has a stiff main tower and the main tower is integrally combined with the building, it is possible to effectively resolve the aesthetic imbalance due to the enlargement of the main tower through the shape of the complex structure and the appearance of the building. .

In addition, the pylons of the cable bridge restrain the horizontal displacement and distortion of the building, and the building also binds the pylon pillars to the structural member gown of the building, thereby restraining the horizontal displacement and distortion of each other. It has the effect of increasing the rigidity of the bridge, so the bridge can economically increase the span length, thereby minimizing the erosion of the communication surface. In the case of a building used as a residential space, the height of the building can be increased and users' psychological anxiety can be solved. In particular, it is possible to further increase the lateral stiffness of the pylon and the building by interconnecting the two buildings facing each other located on both sides of the pylon and effectively utilize the space directly above the bridge deck.

In addition, the main tower of the bridge bears the horizontal load of the building and acts as a supercolumn that actively restrains the horizontal displacement and warpage, thereby alleviating the burden on the horizontal load of the pillar members of the building, and mainly the vertical load. Economical design and construction of members can be achieved. In addition, the girder, which is a horizontal member constituting the ramen structure of the building, serves to bind the pylon pillars of the pylon to contribute to increasing the rigidity of the pylon of the structural member bridge of the building.

In addition, on the other side, people can reside in the building combined with the bridge and Alche, so that the routine maintenance of the bridge can be facilitated, thereby increasing the bridge maintenance level.

In addition, when building construction works in parallel during the construction of bridge construction, some spaces of the building can be used as accommodations and rest spaces for the offices and workers, thereby improving the working environment of workers and eliminating the hassle of safety and entry into the construction site. Can be.

In addition, since the construction of the pylon is preceded, the pylon can be used for fixing cranes, and the bridge can be used as a passageway after the bridge deck is mounted. can do.

As illustrated in the drawing, the main column pillar 11 is composed of four pillar members, each of which has two pillar members in pairs and a pair of pillar members each disposed in an axially orthogonal direction with the upper plate 30 interposed therebetween. It is structurally preferable that the members are symmetrical in plan view, and the pair of two pillar members are arranged at intervals in the axial direction, respectively.

In the case of the cable-stayed bridge, the cross beam direction 13 serves to restrain the gap between the pillar tower columns 11 in the axial direction due to the horizontal component of the cable 20 fixed to the pillar column 11, and at the same time, the pillar column pillar. It also serves to restrain the buckling in (11). In addition, the axial cross beam 13 is connected to a part of the girder 51 or the building pillar 52 located on the outside of the frame structure 50 of the building (B) located on both sides of the main tower 10, the main tower ( 10) and performs the function of structurally connecting the building (B), and also plays a role of restraining the distortion of the pylon column 11 together with the cross beam 12 crosswise direction.

Orthogonal cross beam 12 acts to restrain the buckling and twisting of the pylon column (11). In addition, when the connecting portion 55 is installed between the building units installed on both outer sides of the main column pillar 11, it also serves as a beam for supporting the load of the connecting portion 55 together with the cross beam 13 in the axial direction. The installation position and location of the said crossbeams 12 and 13 can be suitably selected as needed.

As shown in FIG. 3, the building B is integrated with the pylon pillar 11 in contact with the outer side of the pylon pillar 11 in the axially perpendicular direction, and is divided into two building units as shown in the drawing. Each building unit may be built on both sides of the pillar 11. A connection part 55 may be installed between the two building units, and the connection part 55 may be installed in a plurality of locations. That is, as shown in the drawing, the connecting portion 55 may be installed directly on the upper plate 30, and the additional connecting portion 55 may be installed at the top of the pillar column 11. At this time, a gap exists between the two connecting portions 55, and an opening may be formed between the connecting portions 55 by such a gap. Of course, as shown in the figure, the connecting portion 55 may be installed in the lower portion of the upper plate 30. In this case, the connecting portion 55 formed in the lower portion of the upper plate 30 is preferably used as a parking space. That is, it is possible to use the parking facility in the connection portion 55 formed in the lower portion of the upper plate 30 can be used as a parking space for people using the building (B). The connection part 55 installed above the upper plate 30 can be used as a passage between both building units.

The vertical load of the connecting portion 55 is transmitted to the foundation 40 through the pylon column 11, and when the self-weight of the connecting portion 55 is large and there is a risk of burdening the cross section of the pylon pillar 11, part of the load or The building pillar 52 of the building B may bear all.

As illustrated in FIG. 3, the bridge top plate 30 may be provided with a dedicated lane 31 for entering and exiting the vehicle into the building B, and vehicles using the dedicated lane 31 may enter and exit the building B. FIG. A separate doorway 56 may be installed. In the embodiment shown in Figure 3 dedicated lane 31 is installed outside the position where the cable is fixed on the top plate 30, as in another embodiment shown in Figure 5, the axial direction in the building (B) installed position In addition, the widening section 32 which widened the bridge top plate 30 of the predetermined section may be provided to secure a vehicle entry / exit lane to the building B. In this case, the cable 20 may be connected to an edge of the widened bridge top plate 30, and when the cable 20 is connected to the edge of the widened portion, the cable 20 prevents entry and exit of the vehicle. You will not.

In the case of a suspension bridge, the same method as the embodiment shown in FIG. 3 is advantageous, and in the case of a cable-stayed bridge, the same method as the embodiment shown in FIG. 5 may be advantageous. By forming the access-only lane 31 as described above, the user can easily enter and exit the building B through the access-only lane 31 without disturbing the passage of the bridge.

When the traffic volume is not large, the vehicle may be provided by entering and exiting the facing portion of the building B at the main tower position without providing the access-only lane described above. In another embodiment, in the case of a multi-layer bridge in which the upper plate 30 of the bridge is formed of a double layer, the outer lane of the upper or lower upper plate may be used as the entry / exit lane. Sidewalks for the passage of pedestrians are generally provided at the outermost side of the top plate 30, and a separate illustration and description thereof will be omitted.

As illustrated in FIGS. 6 and 7A to 7D, each building unit disposed on both sides of the pylon 10 to form a building B coupled to the pylon 10 may include a plurality of building units in a right angle and a right direction. The frame is constructed by a frame structure 50 consisting of building pillars 52 perpendicular to the girder 51. After such a frame structure 50 is installed, an outer wall including a window and the like is installed as in a conventional building to have an appearance as shown in FIG. 3. 6 and 7A to 7D, the frame inside the connection part 55 is omitted for convenience.

In the present invention in which the building (B) is integrally coupled to the main tower 10 as described above, the main tower 10 is composed of four main tower pillars 11 and cross beams 12 and 13, the central portion of the composite structure Because it is located at, it bears the lateral (bridge direction and perpendicular direction) loads of bridges and buildings, and restrains lateral displacement and distortion of buildings by horizontal loads.

In particular, when blowing in terms of the bridge, the pylon pillar 11 serves to support the cable 20, it has a large cross-section because the rigidity is very large from the perspective of the building from the viewpoint of the building pillar (11) Also serves as a super column that bears the horizontal force acting on the building B and restrains the lateral displacement caused by the horizontal force.

Therefore, most of the building pillars 52 of the frame structure 50 constituting the frame B bear only vertical loads, thereby reducing the installation location and cross section of the building pillars 52, and thus building The cost of the construction of (B) can be reduced.

Orthogonal crossbeam 12 and axial crossbeam 12, which ties the pylon column 11 integrally, also function as a super girder with a large stiffness of large cross-section, and the horizontal displacement and warpage of the pylon column 11 Since it is constrained, it also serves to restrain the horizontal displacement and distortion of the composite structure system of the main column 10 and the frame structure 50. Although not shown in the drawings, if necessary, a slab may be provided on the cross beams 12 and 13 of the main column to increase the rigidity of the main column 10.

In the coupling of the main column 10 and the frame structure 50, the main column 10 includes an axial girder positioned in the direction of the main column of the frame structure 50 among the axial girders of the frame structure 50, as shown in FIG. 7A. Connect it together). In some cases, some of the building pillars 52 may be combined with the crossbeams 13 in the axial direction of the pylon 10, and as shown in FIGS. 7C and 7D, the frame structure 50 faces the pylon. A large cross-section girder 51a may be provided on the side surface of the cross section, and the cross-section girder 51a of the large cross section may be integrally connected with the main column 10. As such, the girder 51, 51a or the building pillar 52 of the frame structure 50 is integrally coupled to the pylon column 11 or the cross beams 12 and 13 of the pylon 10 in various ways, thereby providing a frame structure ( 50 may be integrated with the main column (10).

On the other hand, as shown in Figure 7b, by increasing the cross-section of the building column 52a located in the outer center of the building column 52 constituting the frame structure 50 to perform the function of the super column to the building against the horizontal force It can also increase the stiffness. In addition, by installing a part or all of the girder 51 constituting the frame structure 50 of both buildings B at the position of the connecting portion 55 to cross the main tower, between the main tower 10 and the frame structure 50. The degree of binding can be increased.

The coupling method between the pylon 10 and the frame structure 50 is a method that can be a combination of a rigid coupling that generates a restraint moment, a hinge coupling that does not generate a restraint moment, a roller coupling that allows vertical movement, etc. Since the publicly known technology of the separate illustration is omitted.

On the other hand, the weight of the building is transmitted to the foundation 40 through the building pillar 52, but may have a separate foundation, it may be formed integrally with the bridge foundation supporting the vertical load of the bridge. It is advantageous in construction that the foundation of the bridge foundation and the pillar of the building unite together.
