[0027] The principles and characteristics of the present application are described below in conjunction with the accompanying drawings, and the examples are only used to explain the present application and are not used to limit the scope of the present application.
[0028] As shown in Figure 1 , Figure 3 , Figure 4 , a kind of anti-falling, anti-loose bridge sidewalk board installation structure, including support column, every two adjacent support column is overlapped with sidewalk board 3 between, support column includes column 2, handrail base 1, to prevent sidewalk board 3 from falling off (as shown in Figure 2 It is the installation structure of traditional sidewalk board, and the top of the column is narrow, which can easily cause the sidewalk board to fall off), extension support 5 is arranged on the two sides of the column 2 and the side of the handrail base 1 close to the column 2, so as to increase the support width of the support column to the sidewalk board 3.
[0029] The top of the support column is embedded with anchor bar 4, preferably, the anchor bar 4 is "L" shaped, the part of the anchor bar 4 extending out of the support column is linear, and the horizontal bar at the bottom of the anchor bar 4 is embedded in the support column to enhance its anti-pulling performance. The end of the sidewalk board 3 is provided with a sleeve 6, and the upper end of the anchor bar 4 is inserted into the inside of the sleeve 6. The outer side of the anchor bar 4 is provided with a reinforcing rib to improve the structural strength of the anchor bar 4. The exposed part of the anchor bar 4 needs to be galvanized for corrosion prevention to avoid the influence of steel bar rust on the structure durability, and the diameter of the anchor bar 4 is not less than 16 mm. Specifically, each sidewalk board 3 is embedded with a sleeve 6 at four corner points, the sleeve 6 can use a PVC pipe with a diameter of 32 mm, the anchor bar extends into the sleeve of the sidewalk board, does not affect the normal deformation of the sidewalk board, but can limit the excessive deformation of the sidewalk board, avoid the mutual extrusion and collision of the sidewalk board under the action of local severe impact of external load, and the anchor bar at four corner points can ensure that the sidewalk board does not produce excessive displacement, does not loosen or fall off without structural damage.
[0030] As shown in Figure 5 , Figure 6 , the upper end of the sleeve 6 is provided with an end cover 7, and the end cover 7 is made of stainless steel. Since the sidewalk board 3 is hoisted above the support column, in order to facilitate the smooth insertion of the anchor bar into the sleeve, the diameter of the sleeve is greater than the diameter of the anchor bar, so there will be a gap between the two after the anchor bar is inserted, a trumpet 9 is arranged on the inner side of the lower end of the end cover 7, the lower end of the trumpet 9 can be conveniently inserted into the gap between the two to be appropriately filled, and the shaft section at the trumpet 9 is ladder-shaped to prevent the end cover 7 from being squeezed out when the sidewalk board 3 shakes.
[0031] The side of the end cover 7 is provided with a groove 11, the inside of the groove 11 is sleeved with a corrugated sealing ring 10, the upper end of the corrugated sealing ring 10 is fixedly connected with the end cover 7, and the lower end of the corrugated sealing ring 10 is in sliding contact with the inner wall of the groove 11. The top of the end cover 7 is provided with a handle 8. The corrugated sealing ring 10 is made of rubber, when the end cover 7 is inserted into the inside of the sleeve 6, the corrugated protrusions on both sides of the corrugated sealing ring 10 are crowded together under the action of the friction force of the sleeve, the lower corrugated sealing ring 10 is moved and extruded to the upper side (as shown in Figure 6 The corrugated sealing ring 10 is made of rubber, when the end cover 7 is inserted into the inside of the sleeve 6, the corrugated protrusions on both sides of the corrugated sealing ring 10 are crowded together under the action of the friction force of the sleeve, the lower corrugated sealing ring 10 is moved and extruded to the upper side (as shown in
