The present invention relates to a hypothetical bridge which is installed on a road excavation site or a river to enable passage of a vehicle or a human being. Particularly, the present invention provides a temporary bridge that can be installed in a short time, This is an invention on hypothesis.

Typically, bridges such as rivers are completed by installing bridge piers for long periods of time and roofing, and it is completed by putting the top plate. It takes about 6 months for a concrete box community where small cars can pass from construction to completion, In the case of large-scale congregations, it takes a long period of time of 2 years or more. In addition, it takes several months to cover the incision area for road construction for subway construction, etc. At this time, As a result, it takes more than the minimum incision area of the road to the construction site, which causes the traffic congestion on the complicated roads to increase.

Therefore, it is desirable to install alternative bridges so as not to cause traffic congestion when existing bridges are to be replaced or to be repaired due to their end of life, The present inventors have studied and studied the present invention in detail. The present inventors have completed the present invention by forming a support frame on the upper side of a pair of frame frames opposed to each other, And a plurality of connection frames connecting the frame frame and the support frame in a truss structure are connected to each other by connecting means, and a predetermined reinforcing means is added to the pair of frame structures, And will be described in detail with reference to the drawings. .

FIG. 1 is an enlarged state view of a portion of FIG. 1, which is a side view of the present invention, and FIG. 3 is an overall structural state view of the present invention.

As shown in the drawings, the present invention is characterized in that it comprises a pair of opposed frame frames 11, 11, support frames 12, 12 which are respectively arranged above the frame frames 11, A connecting frame 13 constituting a truss structure between the frame 11 and the supporting frame 12 and fastened by a plurality of bolts 18 by means of a rectangular flat plate 14, A brace 16 is fastened to the inside of the brace 16 with a bolt 18 so as to be connected to a neighboring brace 16 by a bracket pin 17. An extended T- A pair of frame members 1 formed by connecting the brace 16 with the bolts 18 and connecting the brace 16 with the neighboring angle plate 15 and the brace 16 with a pin 17; (2) made up of a plurality of hollow frames (21) installed across the frame (1) across a certain distance and a rectangular flat plate (22) placed on top of the frame frames (21) .

The present invention is characterized in that the frame frames 21 across the frames 1 are mounted on the frame plate 14 attached to the frame frame 11 of the frame 1, Lt; / RTI > A reinforcement frame 31 crossing diagonally across the body frame 21 is bolted to a connection plate 32 attached to the body frame 21 to add a reinforcement body 3 ' desirable.

FIG. 4 is another structural view of the present invention.

The present invention is characterized in that, in the above-described configuration, the double-sided frames (21) crossing the frame (1) are mounted on the support frames (12, 12) of the frame (1) in particular; A connecting plate 32 is attached to the upper and lower portions of the opposing connecting frame 13 and fastened to the pair of reinforcing frames 31 across the pair of reinforcing frames 31 with bolts 18. The upper and lower reinforcing frames 31 are formed in a truss structure And a reinforcing member 3 formed by attaching a connecting rod 33 to be connected thereto.

FIG. 5 is a side view showing an embodiment of the present invention constructed as described above.

In the present invention constructed as described above, since each of the opposing frame bodies 1 is constituted by connecting the frame frame 11 which is vertically arranged and the connection frame 13 of the truss structure of the support frame 12, The frame 11, 12, 13 can be used with any type of steel that can support the structural dynamics load required by the bridge. It can be used as a rigid structure An example of the " H " section steel is as follows, but the present invention is not limited thereto.

The total length of the hypothetical bridge of the present invention changes depending on the width of the river or the length of the excavation road, but the frame frame 11 and the support frame 12, which form the basis of the frame 1 in general, are shorter than the total length, In the present invention, the brace frames 11 are fastened to the inner and outer surfaces of the frames 11 with the bolts 18 and the adjacent braces 16 are overlapped with each other. The angle plate 15 having a "T" shape is fastened to the inner and outer surfaces of the support frame 12 by the bolts 18 and the angle plate 15 adjacent to the support frame 12, Since the hinge structure is constructed by connecting the brace 16 with the bracket 16 or connecting the brace 16 to the angle plate 16 by means of the hinge structure, This is digested. At this time, the overlapping plate 15-15 or the braces 16-16 can be positioned on the inside or on the outside on one side and alternately on the inside, The outer plates 14 and 15 can be easily held by the bolts 18 and the plates 11 and 12 and the plates 14 and 15 The bolts 18 should be fastened with nuts or washers or intercepts of the plates 14 and 15 to avoid interference between adjacent plates 15-15 or braces 16-16, .

Further, since the suspension bridge of the present invention is in the form of a cable-stayed bridge without a pier, when the total length of the bridge is required to be long and large, two or more sets of frame structures (1) In this case, one side of the frame body 1 is opposed in two sets, and the opposite side is provided with one set or a plurality of structures without a structural burden (FIGS. 1 and 3) The present invention is not limited to this structure.

Although the double-side frame 21 mounted across the frame 1 constituted as described above can be installed at any position located at the same height of each frame 1, 3) is mounted on the flat plate 14 attached to the frame frames 11 and 11 and is mounted between the support frames 12 and 12 in another configuration (shown in FIG. 4) The difference between these two structures is that the electrons are suitable for small or medium structures while the latter are suitable for large structures because they are electrons (see FIG. 3) Since the reinforcing member 3 'is composed of the reinforcing frame 31 having a truss structure across the double-side frame 21, the reinforcing member 3' has a planar truss structure. On the other hand, in the latter case 3) is addressed This is because the reinforcing frame 31 constituting the truss structure between the two sets of connection frames 13 has a three-dimensional truss structure.

At this time, the gap between the double-side frames 21 and the length of the double-layered plate 22 must be matched so that the double-layered plate 22 can durably support the vehicles running thereon, It is also possible to attach a stopper 23, which is a piece of an angle, to the body frame 21 in order to do so. It is also possible that the guard post 24 is attached to a predetermined position of the body frame 21 and the guard bar is attached to the guard post 24 so that the vehicle and the vehicle can be divided and installed to pass the vehicle and the vehicle, Are not intended to be exhaustive or to limit the scope of the invention to the ordinary skilled artisan in the art to which this invention pertains.

As described above, the hypothetical bridge of the present invention can be installed anywhere, such as a river or a road excavation site, and all parts of the structure are designed in advance according to the installation site, It is easy to assemble and disassemble. It has high re-installation and material recovery rate. Because it is installed by string type, construction of bridge pier is unnecessary. It is effective as a safe hypothesis.
