The present invention is characterized in that " the outer wall plate 112 and the inner wall plate 113 are coupled to both sides of the bottom plate 111 in an upward direction, A side member (110) formed to have a higher height; The side plate 122 is connected to the side plate 122 in a downward direction on both sides of the upper plate 121 and has a foot member 120); And the inner wall plate 113 are disposed to be spaced apart from each other and disposed to be spaced apart from the two side members 110. The lateral members 130 are disposed at equal intervals; Wherein a plurality of the foot members 120 are mounted on the transverse member 130 so as to form a continuous surface side by side in the width direction between the side members 110 while the foot member 120 disposed on both sides And each of the outer side plates (122) is configured to abut on an inner surface of the outer side plate (112) of the side member (110).

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The longitudinal bridge check stand 100 provided by the present invention is provided with the side member 110, the foot member 120 and the side member 130, as shown in Figs. 3 and 7, A pathway is provided.

4, the side member 110 is a long member having a U-shaped cross-section in which the outer wall plate 112 and the inner wall plate 113 are coupled to both sides of the bottom plate 111 in the upward direction And the outer wall plate 112 is formed higher than the inner wall plate 113. These side members 110 are arranged on both sides of the passage in the longitudinal direction so that a relatively high outer wall plate 112 is located on the outside and a relatively low inner wall plate 113 is located on the inside.

The lateral members 130 are longitudinal members arranged to cross the two side members 110 arranged in parallel to each other with the inner wall plates 113 facing each other.

As the transverse member 130, a round bar may be applied, or a square member may be used.

When the round bar is used as the lateral member 130, the lateral member 130 (round bar) passes through the lower portion of the side member 110 as shown in FIGS. 5 and 6 And both ends thereof are installed and fixed so as to protrude outward from the outer wall plate 112, respectively. A nut or the like may be fastened and fixed in a state where both ends of the transverse member 130 (round bar) protrude through the inner wall plate 113 and the outer wall plate 112 of the side members 110 on both sides. By providing a plurality of the lateral members 130 (circular rods) at equal intervals as described above, the pedestal member 120 is provided with a mounting frame.

When a rectangular member is used as the lateral member 130, an insertion groove 114 is formed in the inner wall plate 113 of the side member 110 from the upper end to the lower end, Both ends of the groove can be inserted and fixed in the insertion groove 114. At this time, any one of T, L, U, I, H, K, and C can be applied to the cross section of the transverse member (130). The forming width and the depth of the insertion groove 114 should be adjusted according to the shape of the slab applied to the transverse member, but the slab should be stably inserted so as not to be separated. 8 illustrates a process of joining the side member 110 by applying a slab having a T-shaped cross-section among the slabs applicable to the side members as the transverse member 130. FIG.

4 and 7, the foot member 120 is a longitudinal member having an ∩-shaped cross-section joined to both sides of the upper plate 121 in a downward direction to form a side plate 122, (122) is formed lower than the outer wall plate (112) of the side member (110). A plurality of such foot members 120 are mounted on the transverse member 130 (circular rod or plate) so as to form a continuous surface side by side in the width direction between the side members 110 to complete the passage of the longitudinal bridge check base 100 do. At this time, the foot members 120 disposed on both sides should be in close contact so that the outer side plates 122 are in contact with the inner surface of the outer side plate 112 of the side member 110, Can be supported by the inner wall plate 113 of the side member 110, so that the safety of the pedestal member 120 can be improved. The upper plate 121 of the foot plate member 120 is positioned lower than the outer plate 112 of the side member 110 in a state where the foot plate member 120 is mounted on the transverse member 130 So that the installation state of the foot plate member 120 and the safety of the operator can be further enhanced. In this case, the outer wall plate 112 prevents the worker's foot from coming out to the outside.

In addition, a foot plate 123 coupled inwardly at the lower ends of the both side plates 122 of the foot plate member 120 may be further configured to allow the foot plate 123 to contact the lateral member 130 . A plurality of perforations 124 may be formed in the upper plate 121 of the foot member 120 to reduce its own weight.

The handrail 140 can be coupled to both sides of the passage configured as described above, that is, outside the both side members 110, as shown in FIGS. 3 to 7. The railing 140 may include a strut 141 formed at equal intervals and a guard bar 142 transversely coupled between the struts 141. The lower end of the strut 141 may include a side wall To the outside of the outer wall plate (113) of the housing (110).

In addition, the present invention can also constitute a support beam 150 which is a long member supporting the both side members 110. The support beams 150 may be formed of L-shaped steel, I-shaped steel, H-shaped steel, c-shaped steel, and various pipes. A plurality of the support beams 150 may be arranged at equal intervals in the lower portion of the side member 110 And the suspension member 160 is coupled to both ends of the support beam 150 so that the suspension member 160 is coupled to a beam or the like on the lower portion of the bridge top plate 1 as shown in FIG. . The suspension member 160 may also be an L-shaped steel, an I-shaped steel, an H-shaped steel, or the like.

1 and 2 show one embodiment of a longitudinal bridge check station 100 configured as described above. While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Accordingly, the appended claims are intended to cover such modifications and changes as fall within the true scope of the present invention.
