Description

Temporary bridge construction method using module member {TEMPORARY BRIDE CONSTRUCTION METHOD USING MODULE MEMBER}

The present invention relates to a temporary bridge construction method using a module member. More specifically, in constructing a temporary bridge by using a temporary vent, various members such as piles, bracing, and support beams for constructing a temporary vent are manufactured in advance as a module member and its supporting member, and the temporary bridge can be easily used by using the same. The present invention relates to a construction method of a temporary bridge using a module member to be constructed.

Figure 1a shows a construction example of the conventional temporary bridge 10, four molds 10 are installed in the transverse direction, it can be seen that the vent plate 20 is installed on the mold 10 and the double plate 20 The load by the vehicle passing through the above) is transferred to the temporary vent 30 supporting the mold 10 via the perforated plate and the mold, so that the load is transmitted to the final ground.

At this time, if the longitudinal extension length of the mold 10 can be longer, since the longitudinal installation interval of the temporary vent 30 can be increased, it is possible to reduce the manufacturing and construction cost of the temporary bridge.

In order to make the length of the temporary bridge 10 longer, the tension member (not shown) is additionally mounted on the bottom of the mold 10 and prestress is introduced to the mold, or a reinforcement plate is further attached to the upper flange of the mold such as an I-beam. Has been introduced to improve the bending stiffness of.

Therefore, it can be seen that the technical development of the conventional temporary bridge 10 is mainly focused on improving the bending rigidity by sufficiently securing the longitudinal extension length of the mold.

A temporary bridge by such a conventional temporary vent 30 is introduced in FIG. 1A.

It can be seen that the temporary vent 30 is provided with a lateral bracing 32 and a longitudinal bracing 33 that restrain the piles 31 which are spaced apart from each other.

Therefore, as the number of piles increases, the number of bracing materials that need to be installed also increases. Therefore, the installation and manufacturing costs of various members for installing a temporary vent such as bracing materials occupy a large proportion in the construction of temporary bridges. It can be seen that.

In particular, since the installation cost of piles takes up a large part of the construction cost of temporary bridges, a temporary bridge construction method for reducing the number of pile installations was introduced in FIG. 1B, which is a temporary bridge using steel pipe piles and pile head brackets. have.

Specifically, it is as follows.

First, the steel bridge pile 40 is constructed along the longitudinal direction in which the temporary bridge is to be constructed.

The steel pipe pile 40 is installed vertically by a pile driving on the ground as a pile of a circular cross section having a predetermined diameter.

At this time, the minimum steel pipe pile 40 is installed, but the steel pipe pile 40 is added to increase the supporting ability.

That is, it adopts a configuration for reinforcing the steel pipe pile 40 is concentrated load. What is installed to exert such a function can be said to be a cap-shaped member which is installed to be covered with a pile head as the pile head bracket 50.

In addition, the mold support 60 may be a member that acts to radially connect the pile head bracket 50 and the mold 70 to each other to distribute the load transmitted from the mold to the pile.

Furthermore, it can be seen that the horizontal head bracket 80 is additionally installed on the upper surface of the pile head bracket 50, which is a member supporting the mold installed in the longitudinal direction.

The mold 70 extending in the longitudinal direction is arranged on the upper surface of the lateral beam 130 by spaced apart a plurality in the horizontal direction.

Furthermore, it can be seen that the steel pipe pile 40 is integrated with each other by separately installing the bracing material 90 between the steel pipe piles 40. Such a bracing material is a member for restraining the piles to allow stable load support. Can be.

That is, the load acting on the temporary bridge compared to the conventional temporary bridge is distributed through the lateral beam, the mold support and the bracing material to be transmitted to the pile, and the pile is reinforced with the pile head bracket to eventually increase the pile's supporting ability. It is to reduce the number of chae seol as much as possible.

In order to construct effective long span bridges, a large number of members such as steel pipe piles (40), pile head brackets (50), transverse beams (80, support beams), and bracing materials (90) have to be installed. Since the members of the site are installed separately in the field, the workability is very poor, which leads to air delay and construction cost increase factors.

Therefore, the present invention can be economically constructed module that can significantly reduce the air while structurally and stably constructing the construction of the temporary bridge in consideration of the operation of the construction equipment and the site conditions, while putting less cost Provision of construction method for temporary bridges using members is a technical problem to be solved.

<Temporary bridge using the module member 200 according to the first embodiment of the present invention>

The temporary bridge using the module member 200 according to the first embodiment is largely the support member 100 for the module member, the prefabricated head bracket 210, the bracing material 220 and the lateral beam as shown in FIGS. 2A and 2B. 230 is largely composed of a module member 200 is integrally coupled.

2b is installed simply by assembling the module member 200 to the support member 100 for the module member in a state in which the support member 100 for the module member is first mounted on the pile 300 constructed as shown in FIG. It is to be completed.

First, the supporting member 100 for the module member may be referred to as a member that is mounted on the pile 300 as shown in FIG. 2A so that the module member 200 described later may be fixed to the pile 300.

The support member 100 for the module member is inserted into the outer peripheral surface of the pile and the support plate 110 of the ring shape formed with a plurality of fastening holes (H); An insertion support plate 120 protruding upwardly on an upper surface of the support plate 110; And a reinforcement plate 130 extending downward on the bottom surface of the support plate 110.

The support plate 110 is a member directly supporting the prefabricated head bracket 210 which will be described later. The support plate 110 and the prefabricated head bracket 210 are fastened to each other by a bolt and a nut to support the file head bracket. The 210 is to be connected to the stable assembly.

The insertion support plate 120 has a plurality of fastening holes (H) in the form of a rectangular vertical plate is inserted into the insertion connection (S) of the prefabricated head bracket 210 which will also be described later bolted to each other in the prefabricated head bracket 210 By being fastened by the nut and the support plate 110 is to be assembled and connected to the prefabricated head bracket 210 in a stable manner.

2a is installed, but two or more may be installed for a stable connection with the prefabricated head bracket 210.

The reinforcement plate 130 may serve to distribute and transfer the load transferred from the support plate 110 to the pile 300 while acting as a guide member to fit the support plate 110 to the pile 300. Accordingly, the reinforcing plate 130 may be formed on the outer circumferential surface of the pile 300 by welding or the like in the form of a plurality of triangular pieces on the bottom of the support plate.

Next, the module member 200 includes a prefabricated head bracket 210, a bracing material 220 connecting the prefabricated head bracket 210 to each other, and a transverse beam 230 installed on the prefabricated head bracket 210. Means the assembled member coupled to.

That is, in the related art, since the pile head bracket, the bracing material, and the lateral beam were separately installed in the pile 300, the present invention can be made into the module member 200, which is an assembly member which is previously integrated with them, and can be installed on the pile at once. It would be.

The prefabricated head bracket 210 connected to each other by the bracing material 220 is arranged in parallel so that at least two or more are arranged in parallel with each other, and the transverse beam 230 is formed on the upper surface of the prefabricated head bracket 210. It is possible, but the module head 200 is manufactured by assembling and connecting the bracing material 220 formed inclined to the prefabricated head bracket 210 by using a bolt and a nut.

In the case of the prefabricated head bracket 210, the final assembly state is formed in a cylindrical shape as a whole, so that two semi-cylindrical brackets 210a and 210b are largely combined to be assembled in a cylindrical form.

The semi-cylindrical bracket (210a, 210b) is a vertical connecting plate (213a, 213b) formed with a plurality of fastening holes (H) up and down on the outer cylindrical surface of the semi-cylindrical vertical body portion (211a, 211b) and the semi-cylindrical vertical body portion, The upper support plate 214a, 214b and the lower support plate 215a, 215b in the form of a semi-circular horizontal plate integrally formed on the upper surface and the lower side of the semi-cylindrical vertical body portion 211a, 211b,

It can be seen that the semi-cylindrical brackets 210a and 210b are connected to each other by being confronted with each other by the bracing material 220 as shown in FIG. 2B.

In this case, the vertical connecting plates 213a and 213b are connected to each other by fastening the semi-cylindrical brackets 210a and 210b, and are also fastened to each other by the insertion connecting plate 120 of the supporting member 100 for the module member. The member and the module member are connected to each other, and also serves to reinforce the semi-cylindrical brackets 210a and 210b while being connected to the bracing material 220.

The upper support plates 214a and 214b in the form of semi-circular horizontal plates are formed with a plurality of fastening holes H to be fastened and connected to the support plates 110 of the support member 100 for module members.

Accordingly, the vertical connection plates 213a and 213b and the lower support plates 215a and 215b of the module member 200 are fastened to each other by the insertion connection plate 120 and the support plate 110 of the support member 100 for the module member. It can be seen that the assembly is connected to each other to be integrated with each other, which is excellent in workability because it uses fasteners and fastening holes (H) such as bolts and nuts.

In addition, the bracing material 220 is installed in such a way as to be installed in a straight or inclined form using a channel member such as L-shaped.

Both ends of the bracing material 220 may be fixed to the vertical connecting plates 213a and 213b of the semi-cylindrical brackets 210a and 210b by using bolts and nuts as shown in FIG. 2B.

Next, the transverse beam 230 is mounted on the upper surfaces of the semi-circular horizontal plate-shaped upper support plates 214a and 214b, which are fastening holes H and the transverse beams formed in the upper support plates 214a and 214b. The fastening holes installed in the 230 may also be assembled by using a bolt and a nut.

Furthermore, the bracing material 220 is inclined to be fixed between the bottom of the transverse beam 230 and the vertical connecting plates 213a and 213b of the semi-cylindrical brackets 210a and 210b using bolts and nuts.

Therefore, as shown in FIG. 2B, the prefabricated head bracket 210, the bracing material 220, and the transverse beam 230 may be formed in an assembled state with each other. It can be seen that one module member 200 is connected to each other in parallel.

For example, if three piles 300 are installed at equal intervals, the support members 100 for the module member described above are installed on the upper portions of the piles 300, respectively, and the two module members 200 are supported for the module members. The construction can be simply connected by connecting to 100 at a time, and the construction air can be drastically reduced in comparison with a construction in which a conventional pile head bracket, a bracing material, and a lateral beam are separately installed.

Looking specifically at these connections

The insertion support plate 120 of the support member 100 for the module member is inserted into the vertical connection plates 213a and 213b of the module member 200 and the insertion connection portion S, which is a space therebetween, and then inserted into the vertical connection plates. It is made by the bolt and nut are fastened through the fastening holes (H) of the support plate 120.

In addition, the support plate 110 of the support member 100 for the module member is made by bolts and nuts fastened through the lower support plates 215a and 215b and the fastening holes H of the module member 200. .

Furthermore, in the case of the prefabricated head bracket 210 of the module member 200, the semi-cylindrical bracket is assembled with the bracing material and the transverse beam, and after the module member is installed in the pile 300, it is added to the semi-cylindrical bracket. Another semi-cylindrical bracket may also be connected to each other by a bolt and a nut using a vertical connecting plate.

As a result, it can be seen that the prefabricated head bracket 210 is formed to have a cylindrical shape on top of the pile 300.

<Temporary bridge construction method using the module member 200 according to the first embodiment according to the first embodiment of the present invention>

3A, 3B, and 3C illustrate the construction method of the temporary bridge using the module member 200 according to the first embodiment according to the first embodiment.

First, as shown in FIG. 3A, three piles 300 form one column, but three piles 300 are installed in the longitudinal direction.

Next, the module member support members 100 described above are respectively installed on the upper ends of the piles 300.

At this time, in order to match the height of the pile is set so that the position of the upper surface of the cut pile 300 and the upper surface of the insertion support plate 120 constituting the support member 100 for the module member.

Next, the modular head bracket 210, the bracing material 220, and the transverse beam 230 are separately prepared to be assembled to the module member support member 100.

The module member 200 can be seen that the two cylindrical prefabricated head bracket 210, the bracing material 220 and the two lateral beams 230 according to Figure 2b is used integrally assembled.

Accordingly, as shown in FIG. 3B, the module member 200 is installed on the support member 100 for the module member installed on the three piles 300.

The installation of the module member 200 is such that the insertion support plate 120 of the support member 100 for the module member as shown in Figure 2b by the vertical connection plate of the prefabricated head bracket 210 of the module member 200 and bolts and nuts. In addition, the lower support plate of the prefabricated head bracket 210 may be fastened to each other by bolts and nuts to the support plate 110 of the support member 100 for the module member.

Further, although not shown, the module member 200 is provided with a semi-cylindrical brackets 210a and 210b between the two piles first, and finally, another semi-cylindrical bracket 210c on the left outermost side. The semi-cylindrical bracket 210a of 200 may be installed to be connected to each other by bolts and nuts fastened to vertical connection plates.

As a result, it can be seen that the module member 200 of the present invention can be assembled and installed according to site conditions in various ways.

Next, it can be seen that the final temporary bridge can be simply completed by disposing the mold 400 in the longitudinal direction on the upper surface of the module member 200 as shown in FIG. 3C.

<Temporary bridge using the module member 200 according to the second embodiment of the present invention>

Temporary bridge using the module member 200 according to the first embodiment of the present invention according to the second embodiment is largely as shown in Figures 4a and 4b for the support member 500, prefabricated head bracket 210, bracing material The large configuration of the module member 200 in which the 220 and the lateral beams 230 are integrally coupled is the same as that of the first embodiment.

Accordingly, as shown in FIG. 4B, the temporary member is simply installed by assembling the module member 200 to the support member 500 for the module member in a state in which the support member 500 for the module member is first mounted on the pile 300. To complete the same is different, the difference is by using the connection method of the module member support member 500 and the module member 200, the module member support member 500 is connected to each other by a transverse connection beam There is a slight difference in the configuration of the module member support member 500 and the module member 200. In detail,

The support member 500 for the module member is inserted into the outer peripheral surface of the pile 300, as shown in Figure 4a and the support plate 510 of the disk form formed with a plurality of fastening holes (H); A reinforcement plate 530 extending downward on a bottom of the support plate 510; And a transverse connecting beam 540 connecting the reinforcing plates to each other.

The support plate 510 is a member directly supporting the prefabricated head bracket 210 to be described below, and the support plate 510 and the lower support plate 215 of the prefabricated head bracket 210 are fastened to each other by bolts and nuts. It is to be reliably connected to the prefabricated head bracket 210 to 510.

The support plate 510 is formed in the shape of a disk and a plurality of fastening holes (H) formed along the outer portion of the fastening hole and the lower support plates (2215: 215a, 215b) of the prefabricated head bracket 210 are formed. In order to communicate with each other and to fasten the bolt and nut and the fastener to the connected fastening holes are assembled to each other.

The reinforcement plate 530 may serve as a guide member in which the support plate 510 is fitted to the pile 300, and serves to distribute and transfer the load transferred from the support plate 510 to the pile 300. Accordingly, the reinforcing plate 530 may be formed on the outer circumferential surface of the pile 300 by welding or the like by using a plurality of triangular pieces in the bottom of the support plate.

The lateral connecting beams 540 are for connecting and restraining the support member 500 for the module member spaced apart from each other as both ends in the fastening hole (H) formed in the reinforcing plate 530 using a channel member or the like. To be installed by fastening with bolts and nuts.

Thus, in Embodiment 2, it can be seen that the module member support member 500 can also be integrated with each other so that it can be integrally installed in the file 300. Thus, in contrast to Embodiment 1, the insertion support plate is not provided. Able to know.

Next, as shown in FIG. 4B, the module member 200 includes a prefabricated head bracket 210, a bracing material 220 connecting the prefabricated head bracket 210 to each other, and a transverse beam installed on the prefabricated head bracket 210. Meaning of the assembly member 230 is integrally coupled is the same as in Example 1.

That is, in the related art, since the pile head bracket, the bracing material, and the horizontal beam are separately installed in the pile 300, the present invention makes the module member 200 which is an assembly member which is previously integrated with them, and installs them at the same time. I would have to.

The prefabricated head bracket 210 connected to each other by the bracing material 220 is arranged so that at least two or more are arranged in parallel with each other, and the transverse beam 230 is formed on the top surface of the prefabricated head bracket 210, but is transversely. The module member 200 is manufactured by connecting the bracing material 220 which is inclined from the bottom surface of the directional beam center to the assembled head bracket 210 using bolts and nuts.

In this case, the prefabricated head bracket 210 is formed in a cylindrical shape as a whole in a final assembly state, so that two semi-cylindrical brackets 210a and 210b are largely assembled to be assembled in a cylindrical shape.

Accordingly, the semi-cylindrical brackets 210a and 210b also have vertical connection plates 213 and 213a having a plurality of fastening holes H formed on the outer circumferential surface of the semi-cylindrical vertical body portions 211 and 211a and 211b and the semi-cylindrical vertical body portion. (213b), the upper support plate (214; 214a, 214b) and the lower support plate (215; 215a, 215b) in the form of a semi-circular horizontal plate integrally formed on the upper surface and the lower side of the semi-cylindrical vertical body portion (211a, 211b) It is configured, it can be seen that the semi-cylindrical bracket (210a, 210b) are opposed to each other to be connected while being restrained by the bracing material 220.

In this case, the vertical connecting plate 213 is connected to each other by fastening the semi-cylindrical brackets, and also serves to reinforce the semi-cylindrical brackets while acting to be connected to the bracing material, and unlike the embodiment 1 to the insertion support plate Since the semi-cylindrical vertical body parts are not spaced apart from each other, the insertion support plates are closely connected to each other so that the insertion connection part S is not formed.

Also, as shown in FIG. 4B, the lower support plates 215: 215a and 215b of the semi-circular horizontal plate form are formed with a plurality of fastening holes to be fastened and connected with the support plate 510 of the support member 500 for a module member.

Accordingly, it can be seen that the lower support plates 215 and 215a and 215b of the module member 200 are integrally connected to each other by being connected to the support plate 510 of the support member for the module member. It can be seen that workability is excellent because of the use of spheres and fastening holes.

In addition, the bracing material 220 is also installed in such a way as to be installed in a straight or inclined form using a channel member such as L-shaped.

Both ends of the bracing material 220 may be fixed using bolts and nuts, etc., to the vertical connection plates 213; 213a and 213b of the prefabricated head bracket 210, that is, the semi-cylindrical brackets 210a and 210b.

Next, the transverse beam 230 is mounted on the upper surfaces of the semi-circular horizontal plate-shaped upper support plates 214a and 214b, which are fastening holes and transverse beams 230 formed in the upper support plates 214a and 214b. The bolts and nuts are also connected to the fastening holes installed in the socket.

Furthermore, the bracing material 220 is provided with a fastener such as a bolt and a nut between the bottom surface of the transverse beam 230 and the vertical connecting plates 213a and 213b of the prefabricated head bracket 210, that is, the semi-cylindrical brackets 210a and 210b. It is preferable to fix by using.

Therefore, as shown in FIG. 4B, the prefabricated head bracket 210, the bracing material 220, and the transverse beam 230 are formed in an assembled state with each other. It can be seen that the two module members 200 can be used in a state of being connected in parallel (straight line) to each other.

For example, if the pile 300 is also provided at three equal intervals, the pile member supporting member 500 integrated with the lateral connection beam 540 previously described above are integrally installed on the pile 300, respectively, It can be easily installed by connecting the two module members 200 with the support member 500 for the module member at a time. Can be reduced.

Looking specifically at these connections

The support plate 510 of the support member 500 for the module member is made by bolts and nuts fastened through the lower support plates 215; 215a and 215b and the fastening holes H of the module member 200.

Furthermore, although not shown, in the case of the prefabricated head bracket 210 of the module member 200, the semi-cylindrical bracket is assembled with the bracing material and the transverse beam, and after the module member is installed in the pile, it is added to the semi-cylindrical bracket. Another semi-cylindrical bracket may also be connected to each other by a bolt and a nut using a vertical connecting plate.

As a result, it can be seen that the prefabricated head bracket 210 is formed to have a cylindrical shape on top of the pile 300.

<Module member (B) construction method according to the second embodiment of the present invention>

5A, 5B and 5C show the construction method of the module member A according to the third embodiment in order.

First, as shown in FIG. 5A, three piles 300 form one column, but three piles 300 are installed in the longitudinal direction.

Next, the support members 500 for the module members connected to each other by the horizontal connection beam 540 described above on the upper ends of the piles 300 are integrally installed at a time.

This is to reduce the effort to install each of the support member 500 for the module member to the pile.

At this time, the support plate 510 of the support member 500 for the module member 500 is in close contact with each other on the upper surface of the cut file 300 to fit the height of the pile support for the module member connected to each other with a transverse connecting beam 540 on the upper surface of the pile It can be seen that the member 500 is supported and installed.
