The present invention relates to a temporary vent structure by a transverse cap beam and a double hinge bearing. More specifically, in constructing temporary vents installed to construct temporary structures, such as temporary bridges, temporary building structures, etc., it is possible to optimize the number of installations and cross-sectional design of substructures, especially column members, so that the construction of temporary vents is economical. The present invention relates to a temporary vent structure with a transverse cap beam and a double hinge bearing having improved workability.

1A illustrates a temporary bridge using a conventional temporary vent.

In other words, the pillar members 11, which are H beams, are introduced into the ground one by one using a hydraulic vibrator, and then a plurality of H beams are connected to each other by using inclined members that are L-shaped steel and reinforcing members 12 and 13 which are horizontal members. Complete the substructure 10 of the temporary vent in the form of a pillar member assembly,

After installing the longitudinal temporary beam 21 on the upper portion of the substructure 10, by installing a perforated plate 22 on the upper portion of the temporary beam to complete the upper structure 20 of the temporary bridge to construct a general temporary bridge.

In addition, after installing the substructure 10 composed of the pillar member and the reinforcement member on the ground 40 to install the permanent bridge, it is also used as a copper bar structure for installing slab formwork for bridge construction, etc. 10, the cap beam 30 is installed and used as the H beam as shown in FIG. 1B.

The temporary vent consisting of the lower structure 10 and the upper structure 20 as described above is to install the longitudinal temporary beam 21 by welding or bolt on the top of the pillar member 11 that is the H beam.

In this case, in particular, the installation method by welding has a problem in that safety and workability are very poor because the welding operation requires an upward work by the worker as shown in FIG. 1C, and the pillar member 11 and the upper structure are also structurally welded. Since the 20 is rigid with each other, the lower part of the pillar member 11 has a bending moment corresponding to the bending moment occurring in the steel part, and when designing the pillar member in consideration of this, it is inevitable to design a pillar member having a large cross section. There was a problem that it could be an increase factor of infrastructure fabrication cost.

In addition, the installation method using the bolt uses a method of using a bolt and nut to the folding member 50, such as a c-shaped channel between the pillar member 11 and the pillar member 11, such a bypass pillar member 11 and The connection method of the superstructure 20 has a dynamic problem that the working load transmitted from the superstructure may not be transmitted well to the pillar member 11.

Furthermore, as shown in FIG. 1D, a temporary support (hinge support) 60 for temporary vents is installed between the bottom of the longitudinal construction beam 21 and the upper surface of the pillar member 11, as shown in FIG. 1D. Compared with the installation method, etc., the construction is excellent, and the pillar member 11 directly bears the working load transmitted from the upper structure to follow a more efficient load transfer mechanism. Yong temporary support has to be increased by the number of installation of the longitudinal construction beam, and the column member also has to be installed respectively under the temporary support for the temporary vents, there was a problem that becomes a big obstacle in the production of economical substructure.

Furthermore, since the movement is constrained by the connecting bolt 61 connecting the longitudinal temporary beam and the pillar member up and down, when a horizontal force occurs due to the temperature, a bending moment that can resist this occurs in the lower pillar member. There is a problem in that it is an obstacle to the production of economical substructure like the welding connection method. As a result, such a conventional temporary vent not only requires the installation of a large number of pillar members in the substructure, but also has a problem in that it is necessary to design an uneconomic cross-sectional shape.

In order to solve the problems of the prior art of the present invention, an object of the present invention is to transmit the load transmitted from the superstructure to the ground, while the transverse cap beam and the double hinge support can be installed as an economical substructure It is to provide a temporary vent structure.

The present invention to achieve the above technical problem,

First, by installing a horizontal kaepbim 130 between the longitudinal construction beam 210 and the pillar member 110 of the upper structure 100, the hinge support is installed between the upper surface and the longitudinal construction beam of the transverse kaepbim 1 The working load transmitted to 140 is not directly transmitted to the pillar member, but is transmitted to the pillar member via a cap beam extending in the lateral direction.

That is, in the related art, since the working load is transmitted directly to the pillar member 110 via the hinge support 1 140, the simple structure of the pillar must be installed as much as the number of installation of the hinge support 1 140. However, in the present invention, the pillar member 140 supports the lateral cap beam 130 in a state in which the lateral cap beam 130 receives a primary working load transmitted from the plurality of hinge supports 1 140. Since it is converted to a beam-column structure as a whole, the pillar member 110 can be installed in a smaller number than in the prior art, and the number of pillar members to be infiltrated into the ground can be reduced, thereby increasing the cost of the construction members. The installation cost can be reduced.

Second, by installing a hinge support 2 (120) between the transverse kaepbim 130 and the pillar member 110, the workability is improved in the installation of the pillar member 110 on the bottom of the transverse kaepbim 130 . That is, in the case of installing the horizontal cap beam 130 on the upper surface of the pillar member by welding or bolting, the hinge support 2 120 may be disposed between the horizontal cap beam 130 and the pillar member 110 in consideration of poor workability. It was installed more.

In addition to the hinge support 1 (140) by the hinge support 2 (120) in the substructure of the present invention is a structure that does not generate a bending moment (only the upper and lower axial force is transmitted to the substructure), so that the efficient design of the lifting member It was made possible.

Third, by installing the fall prevention means 400 for restraining the pillar member 110 and the transverse kaepbim 130 up and down, even without restraining the horizontal movement of the longitudinal temporary beam 210 of the transverse kaepbim 130 To prevent the fall, more stable construction of temporary vents was possible.

In order to achieve the technical problem, the temporary structure of the present invention is

A hinge support 1 (140) mounted between an upper structure (200) including a plurality of longitudinal temporary beams (210) and a transverse kap beam (130) extending over the entire width of the bottom of the upper structure; And a hinge support 2 (120) mounted between the bottom surface of the lateral kaepbim 130 and the top surface of the pillar member (110).

The hinge support 1 (140) or the hinge support 2 (120) is an elastic support (123,143) between the upper plate and the lower plate; And a lower guide block installed on an upper surface of the lower plate outside the upper guide block installed on the bottom surface of the upper plate in order to restrain the displacement of the upper plate.

A bracket 300 installed around the pillar member connecting the lateral kaepbim 130 and the pillar member 110 up and down; And a connection bolt having a lower end fastened to the bracket with a fastening nut, and an upper end fastened with a fastening nut to an upper support plate installed on the upper side of the lateral cam beam. It was installed more.

BRIEF DESCRIPTION OF DRAWINGS To describe the present invention more clearly and easily, the following describes the best embodiments of the present invention in detail with reference to the accompanying drawings, and the embodiments according to the present invention can be modified in many different forms. The range is not limited to the embodiments described below.

Figure 2 shows a schematic view of the substructure of the temporary structure of the present invention, Figures 3a and 3b shows examples of the transverse kaepbim of the present invention, Figure 4 is a transverse direction by the bracket and the support plate It shows an example of the fall prevention means installed in the kaepbim.

The temporary vent structure of the present invention may be applied to a substructure including a pillar member or a pillar member assembly, or a temporary vent structure in which a longitudinal hollow beam is installed on the upper portion of the substructure and a perforated plate is further installed on the temporary beam.

That is, as a temporary bridge, the pillar members, which are H beams, are inserted into the ground, or the H beams are connected to each other with reinforcing members, so that a longitudinal temporary beam is installed on the temporary structure of the temporary vent fabricated by the pillar member assembly. It can be used as a temporary vent for constructing a ventilating plate or a substructure installed as a copper bridge structure for permanent bridges, and a cap beam installed on an upper portion of the substructure.

Accordingly, the lower structure 100 of the present invention is to install the pillar member 110 on the ground 40 as shown in Figs.

The pillar member 110 may be installed by incorporating a conventional H beam into the ground 40 as a hydraulic vibrator, but is not necessarily limited thereto.

The hinge support 2 (120) is installed on the upper surface of the pillar member (110). The hinge support 2 (120) may be configured to include an elastic support 123 installed between the lower plate 121 and the upper plate 122, as shown in Figure 4, the lower surface of the upper plate 122, the displacement of the upper plate The upper guide block 124 is installed to restrain the formed further, the lower guide block 125 on the upper surface of the lower plate 121 on the outside of the upper guide block 124;

Thus, when the upper plate 122 is moved horizontally by the working load, the upper guide block 124 is caught by the lower guide block 125 of the lower plate to prevent the horizontal movement that is not allowed to limit the upper plate 122 To prevent the fall of the transverse kaepbim 130 formed integrally with the.

The hinge support 2 (120) installed on the upper surface of the pillar member 110 is installed to support the lateral kaepbim 130, in a manner that is mounted on the pillar member 110, which is pre-installed by a lifter such as a crane Is installed.

The transverse kaepbim 130 may use an H beam, but may use a beam manufactured in another cross-sectional shape, or may use a tubular or box-shaped beam.

3A and 3B illustrate examples that may be used as the transverse kapbeam 130.

3A shows that the H-beam can be used as the transverse kap-beam 130,

3B illustrates that a square tube or box body may be used as the lateral kaepbim 130.

That is, in using the lateral kaepbim 130, it can be seen that it is possible to determine and install a variety of cross-sectional structure and shape (circular tube is also possible), which is advantageous in bending, torsion, buckling, workability and economics.

Since the lateral kaepbim 130 is an upper structure and is installed to extend in the transverse direction on the bottom of the longitudinal hypothesis beam is subjected to the total load transmitted from the longitudinal hypothesis beam 210, this load is the pillar member 110 ).

Accordingly, the pillar member 110 of the present invention does not need to be directly loaded from the longitudinal temporary beam 210, so it is not installed at the bottom of each longitudinal temporary beam as in the prior art, and has a length on the bottom surface of the horizontal cap beam 130. It is installed on the hinge support 2 (120) installed less than the number of directional construction beam (210).

On the upper surface of the lateral cap beam 130, a hinge support 1 (140) such as hinge support 2 (120) is installed.

The hinge support 1 (140) may also be configured to include an elastic support 143 installed between the lower plate 141 and the upper plate 142, such as the hinge support 2 (120), the upper plate 142 bottom The upper guide block 144 installed to restrain the displacement of the plate is further formed, and the lower guide block 145 on the upper surface of the lower plate 141 on the outside of the upper guide block 144; .

As an example of the hinge bearings 1 and 2 as above, the elastic bearing method has been introduced, but various other hinge bearings can be used.

A longitudinal temporary beam 210 is installed on an upper surface of the hinge support 1 140, and a perforated plate 220 is installed on an upper surface of the longitudinal temporary beam 210. The longitudinal temporary beam 210 and the perforated plate 220 is referred to as the upper structure 200 in the present invention.

Looking at the load transfer mechanism by the substructure 100 and the superstructure 200 of the hypothesis vented above,

A traffic load such as a vehicle acts on the perforated plate 220, such a load is supported by the longitudinal temporary beam 210.

Since the longitudinal temporary beam 210 is a bending member, it resists the bending moment due to the load, and a vertical reaction force is generated in the hinge support 1 140 supporting the longitudinal temporary beam 210. .

This point reaction was to support the pillar member directly supporting the conventional hinge support 1 (140), which can be unnecessarily increased because the number of pillar members need to be installed for each hinge support 1 (140). .

That is, it is common to use the H beam as a pillar member, but it may not be possible to intrude the H beam according to the ground (rock layer, etc.), and even if it is possible, the main factor of air and construction cost increase and decrease because it is very poor in construction. There was no choice but to act.

In addition, heavy equipment such as a hydraulic vibrator is required to penetrate the H-beam into the ground, so when accessibility of the equipment is not easy, there are many difficulties in the installation work of the pillar member. There is a need to improve economics.

Accordingly, in the present invention, the horizontal cap beam 130 is installed below the hinge support 1 so as to reduce the number of installation of the pillar member.

That is, since the lateral cap beam 130 is a bending member, only the pillar member 110 is installed to support the bending member so that the number of installation of the pillar member can be reduced.

In addition, in the present invention, since the load is transmitted through the horizontal cap beam 130 of the hinge bearings 1,2 (120,140) that do not restrain rotation, the bending moment does not occur in the pillar member 110 due to the working load. The pillar member can be designed as a member.

That is, the bending moment may not be considered in the cross-sectional design of the pillar member, so that the pillar member having a more economical cross section may be designed and manufactured.

As a result, the conventional temporary vent substructure acts as a simple pillar member (hinge bearing 1 and pillar member), but the present invention is a beam-pillar member (hinge bearing 1, transverse cap beam, hinge bearing 2 and pillar member). It is possible to reduce the number of installation of the pillar member by the action, and to enable an efficient cross-sectional design of the pillar member.

Accordingly, the present invention can express the technical effect by the transverse cap beam and the double hinge bearing.

Figure 4 is to prevent the conduction of the transverse kaepbim in installing the pillar member 110, the hinge support 2 (120), the transverse kaepbim 130, the hinge bearing 1 (140) and the longitudinal temporary beam 210 as described above It shows a state in which the bracket 300 and the fall prevention means 400 installed to be installed together.

The pillar member 110 is installed using the H beam, and it can be seen that the bracket 300 is installed at the upper end thereof.

The bracket 300 has an upper horizontal plate 310 installed so as to extend left and right on the column top surface, a yarn 320 for fixing the upper horizontal plate 310 to the pillar and a lower portion connecting the upper member to the column top. It may be composed of a connection member 330, it is preferable to be able to install the pre-fabricated bracket 300 to the upper end of the pillar member by processing the iron plate.

Since the upper horizontal plate 310 of the bracket can secure a wider upper cross-sectional area, it is easy to install the hinge support 2 (120), and can act as a footrest of the worker, thereby improving the workability of the worker.

Hinge support 2 (140) is installed using an elastic support, it is installed on the upper surface of the upper horizontal plate of the bracket.

The transverse kaepbim 130 is installed on the upper surface of the hinge support 2 (140) as a box beam instead of an H beam.

This box body beam is formed in a square tube shape so that the upper and lower surfaces can be easily supported and installed on the hinge support, and has an advantage in that it is advantageous to twisting and buckling as a bending member. It is desirable to install a horizontal / vertical stiffener therein to enhance its rigidity.

The upper support plate 410 is installed by processing a steel plate on the upper surface of the transverse cap beam 130, which is a box body beam.

The upper support plate 410 is to form a through hole in advance so that the connection bolt 420 can be penetrated and fastened.

In addition, through holes are also formed in the upper horizontal plate 310 of the bracket 300 in advance, so that the connecting bolt 420 is inserted into the through holes, and the fastening bolts 430 are fastened to the screw portions formed at each end. The lateral kaepbim 130 is to be connected to the bracket 300.

Accordingly, the transverse cap beam 130 can be prevented from being conducted by an unstable state due to the working load or the like.

Accordingly, the bracket 300, the connection bolt 420, the fastening nut 430, and the upper support plate 410 are referred to as fall prevention means 400.

As a result, in the related art, a bending moment due to constraining the longitudinal temporary beams from each other via the pillar member and the hinge support 1 is generated in the lower part of the pillar member, as shown in FIG. 1C. By limiting the horizontal movement by, 2, not only the bending moment of the pillar member is prevented from being generated by the longitudinal temporary beam, but also the lateral cap beam is connected to the pillar member by the fall prevention means, thereby connecting the lateral cap beams to each other. It is not necessary to secure the stability to enable the stable installation and construction of temporary vents.

The temporary vent structure by the transverse cap beam and the double hinge support of the present invention not only can reduce the number of installation of the pillar member as a substructure of the temporary vent, but also can be designed as a more efficient cross-sectional pillar member. It is possible to manufacture and install a stable temporary vent.

An embodiment of the present invention described above and illustrated in the drawings should not be construed as limiting the technical spirit of the present invention. Those skilled in the art of the present invention can modify and change the technical spirit of the present invention in various forms. Therefore, such improvements and modifications fall within the protection scope of the present invention as long as it will be apparent to those skilled in the art.
