Description

  The present invention relates to a floor joint plate that covers a joint portion between left and right floor frames provided via joint portions so that a vehicle or the like can travel.

  Conventionally, this type of floor joint plate is a square shallow plate-shaped joint plate body made of metal, and flat steel or I-shaped bars are arranged in parallel at intervals of 28.3 mm in the joint plate body, and a plurality of upper sides are formed. Insert a grid-shaped reinforcing body fixed by a bar member or weld and fix the grid-shaped reinforcing body to the bottom surface of the joint-plate main body so that the grid-shaped reinforcing body is embedded in the mortar. It was configured with filling.

  However, in a floor joint plate constructed by storing a grid-like reinforcing body in the joint plate body, when the mortar is filled in the joint plate body, the center portion of the joint plate body is bent downward by the load, and rain There was a problem that rain sometimes accumulated on the upper surface of the bent area.

  In addition, if the grid-like reinforcements are fixed to the bottom surface of the joint plate body by welding, a sufficient reinforcing effect can be obtained, but the bottom surface of the joint plate body is burnt by welding and has the disadvantage of causing rust. Since a grid-like reinforcement body in which flat steel or I-type bars are arranged in parallel at intervals of 28.3 mm is used, concrete aggregate does not enter the grid-like reinforcement body, so only mortar made of sand and cement is used as a joint. There was a drawback that the plate body could not be filled and sufficient reinforcement could not be obtained.

JP 2011-157722 A

  In view of the above-described conventional drawbacks, the present invention can provide sufficient strength even when concrete is filled in the joint plate body, and sufficient strength can be obtained, and a plurality of reinforcing bar holders can be joined by spot welding. The purpose of the present invention is to provide a floor joint plate that can efficiently prevent the central portion of the joint plate from being rusted without being bent by a plurality of reinforcing bars.

Reinforcing bar support portions 12a, 12a and welds X, X, X, X inserted into the bar insertion grooves 11, 11, 11, 11 and the upper ends of the plurality of reinforcing bar insertion grooves 11, 11, 11, 11 A plurality of reinforcing bars 13, 13, 13, 13 fixed by a plurality of reinforcing bars holders 12, 12, 12, 12 and a plurality of reinforcing bars 13, 13, 13 in the joint plate body 9. Covering 13 The concrete 14 filled in the middle, the cover plate 16 attached to the upper part of the front end portion of the joint plate main body 9 via a hinge member 15, and the lower ends attached to both sides of the rear part of the joint plate main body 9 are opened. The support plate insertion cylinders 18 and 18 constituting part of the joint plate support device 8 communicated with the engagement pin insertion holes 17 and 17 formed on both sides of the rear portion of the joint plate body 9. Yes.

   As shown in FIG. 4, the plurality of reinforcing bar holders 12 are trapezoidal contour shapes in which the upper part of the height of the joint plate body 9 is less than half of the height dimension, for example, a quarter height. A plurality of reinforcing bar insertion grooves 11, 11 having the same size as the thickness of the reinforcing bar 13 on both side plates 12 a, 12 a so as to have a distance of 90 mm or more into which concrete aggregate enters. , 11 and 11 are used.

  As shown in FIG. 6, the plurality of reinforcing bars 13 are approximately half the height of the joint plate main body 9 and have a cross-section having a thickness dimension substantially the same as the groove width of the reinforcing bar insertion groove 11. Rectangular flat steel is used.

  Support pins 19 and 19 constituting a part of the joint plate support device 8 are fixed to the joint plate support recess 6 so that the heads are inserted into the support pin insertion cylinders 18 and 18 of the floor joint plate 7. Has been.

  In the floor joint plate 7 having the above-described structure, the plurality of reinforcing bar holders 12, 12, 12, 12 positioned in the joint plate body 9 are fixed to the bottom surface of the joint plate body 9 by spot welding 10. The bottom surface of the plate main body 9 has a small burn mark due to welding because of spot welding, and can efficiently prevent rusting.

  Further, the reinforcing bars 13, 13, 13, 13 are inserted into the plurality of reinforcing bar insertion grooves 11, 11, 11, 11 of the plurality of reinforcing bar holders 12, 12, 12, 12, and the reinforcing bar support portions 12a, Since the upper part of 12a and the reinforcing bars 13, 13, 13, 13 are fixed by welding X, X, X, X, a plurality of reinforcing bar holders 12, 12, 12, 12 and a plurality of reinforcing bars 13, 13 , 13, 13 can be firmly fixed, and a plurality of reinforcing bar holders 12, 12, 12, 12 and a plurality of reinforcing bars 13, 13, 13, 13 are welded X, X, X, X The fixed burn mark at the bottom does not appear on the bottom surface of the joint plate body 9.

  Further, the aggregate 14a of the concrete 14 filled in the joint plate body 9 also enters between the plurality of reinforcing bar holders 12, 12, 12, 12 and the plurality of reinforcing bars 13, 13, 13, 13. The joint plate body 9 can be reinforced with the concrete 14.

  The floor joint plate 7 configured as described above has a rear end portion of the floor joint plate 7 such that the support pins 19 and 19 of the joint plate support recess 6 enter the support pin insertion cylinders 18 and 18 of the rear end portion. Is attached to the joint plate support recess 6 and the tip is attached to the joint plate slide support recess 5 so that the upper surfaces of the left and right floor frames 3 and 3 and the upper surface of the joint plate 7 are substantially flush with each other. The vehicle can run.

  When the left and right floor frames 3 and 3 are swung so that the joint 2 is narrowed by the earthquake, the tip of the floor joint plate 7 is pushed up along the inclined surface 4 of the joint plate slide support recess 5 as shown in FIG. However, since the tip end portion of the cover plate 16 is kept in contact with the floor frame 3, the inclined projection surface 20 is formed, but the vehicle or the like can be safely run.

  When the left and right floor frames 3 and 3 are swung so that the joint portion 2 is widened by the earthquake, the tip of the floor joint plate 7 slides on the joint plate slide support recess 5 as shown in FIG. Absorbs shaking motion.

  At this time, when the front end portion of the cover plate 16 enters the joint plate slide support concave portion 5, the concave portion 21 is generated. However, since the concave portion 21 is relatively small, traveling of the vehicle or the like is possible.

  In the embodiment of the present invention, the floor plate joint plate 7 is provided in the joint plate slide support recess 5 and the joint plate support recess 6. However, the present invention is not limited to this and the joint plate slide support recess is not limited thereto. 5 may be covered with a joint plate slide support recess base material made of a metal material, or the joint plate support recess portion 6 may be covered with a joint plate support recess base material made of a metal material.
