Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to municipal engineering technical field, concretely is a prefabricated integrated sidewalk board. BACKGROUND
[0002] In the field of sidewalk construction, the traditional municipal sidewalk construction usually adopts the on-site assembly mode of combined floor tiles. However, the block-by-block laying of combined floor tiles requires a large amount of manpower and time; during the construction process, due to size adjustment, splicing errors and loss, the floor tile material is also wasted; at the same time, the on-site assembled floor tiles, due to the uncontrollability of the splicing gap, result in poor overall appearance, and the flatness of the splicing part is difficult to guarantee.
[0003] At present, there are also some prefabricated sidewalk boards on the market, but most of the products still have the following shortcomings in actual application:
[0004] 1. The existing prefabricated sidewalk board has a large self-weight, which increases the difficulty of transportation and installation; at the same time, the large self-weight is prone to sinking or cracking when the ground bearing capacity is insufficient; and the internal structure stress is concentrated due to the self-weight, cracks or deformation occur after a long time of use, which shortens the service life.
[0005] 2. Most of the existing sidewalk boards only have basic bearing function, lack of optimization design for rainwater discharge, water permeability and comprehensive performance. INVENTION CONTENTS
[0006] The utility model aims at providing a prefabricated integrated sidewalk board which is light in quality and has water permeability.
[0007] The prefabricated integrated sidewalk board provided by the utility model comprises an integrated sidewalk board and a curb, the sidewalk board is supported by a column, the panel of the sidewalk board is water permeable and provided with drainage holes to discharge rainwater.
[0008] In an embodiment of the sidewalk board, the sidewalk board, the curb and the column are a one-time pouring integrated base, the shape of the base is a reversed L shape, the horizontal edge is the sidewalk board, and the vertical edge is the curb.
[0009] In an embodiment of the sidewalk board, the bottom end of the sidewalk board is uniformly provided with a plurality of holes.
[0010] In an embodiment of the sidewalk board, the holes are right prism holes, and the gap between the holes is a support beam.
[0011] In an embodiment of the sidewalk board, the intersection of the support beam is provided with the column.
[0012] In an embodiment of the above sidewalk board, the column is a rectangular column.
[0013] In an embodiment of the above sidewalk board, the top surface of the sidewalk board is provided with a secondary pouring groove and a blind area, and the blind area is provided with a sidewalk for the blind.
[0014] In an embodiment of the above sidewalk board, the bottom of the secondary pouring groove is inclined to the curb, and the curb is provided with a drainage hole.
[0015] In an embodiment of the above sidewalk board, the top surface of the sidewalk board is uniformly provided with no less than three lifting lugs.
[0016] The beneficial effects of the present application are as follows:
[0017] 1. The column support and the reserved hole greatly reduce the self-weight of the prefabricated component, reduce the difficulty of transportation and installation, and reduce the pressure on the foundation bearing. At the same time, the column arranged at the beam joint also reduces the risk of stress concentration of the overall structure, avoids cracks and deformation of the board due to self-weight or long-term use, thereby prolonging the service life.
[0018] 2. The upper concrete adopts a water-permeable concrete material, and in combination with the drainage hole reserved on the side surface, the sidewalk board can quickly drain the surface water in rainy days, thereby improving the anti-skid performance of the sidewalk. BRIEF DESCRIPTION OF DRAWINGS
[0019] Figure 1 It is an axonometric structural schematic view of an embodiment of the present application.
[0020] Figure 2 It is an axonometric structural schematic view of another perspective of the present application. Figure 1 DETAILED DESCRIPTION
[0021] The related technical solutions will be described in detail below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments, not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0022] In combination with Figure 1 and Figure 2 It can be seen that the prefabricated integrated sidewalk board disclosed in the present embodiment comprises a sidewalk board 1, a curb 2, a column 3, water-permeable concrete 4, a sidewalk for the blind 5, and a lifting lug 6.
[0023] The sidewalk board, curbstone and column are integrally formed by one-time pouring, the pervious concrete is formed by secondary pouring, and the sidewalk for the blind and the hanging nail are set subsequently.
[0024] The pedestal is a L-shaped part with a reverse buckle, the horizontal side is the sidewalk board 1, and the vertical side is the curbstone 2.
[0025] The bottom end of the sidewalk board is uniformly provided with 4 rows and 4 columns of total 16 prismatic holes, and the remaining 3 gaps in the horizontal and vertical directions are used as support beams, so that the overall quality of the sidewalk board can be reduced while ensuring normal use.
[0026] Rectangular columns 3 are arranged at the junction of the support beams to provide support and further reduce the overall quality.
[0027] The top end of the sidewalk board 1 is provided with a secondary pouring groove and a blind area, and the sidewalk for the blind 5 is installed on the blind area. The secondary pouring groove is poured with pervious concrete, and the groove bottom is slightly inclined downward toward the curbstone. The curbstone is provided with a row of drainage holes, and the rainwater passing through the sidewalk board can be quickly discharged from the side through the inclined groove bottom and the drainage holes in rainy days.
[0028] After the sidewalk board 1 is completely poured, four hanging nails 6 are uniformly punched on the top surface to facilitate subsequent construction and installation. After installation, the hanging nails can be removed and the hanging nail holes can be closed.
[0029] The advantages of using the prefabricated integrated sidewalk board are as follows:
[0030] 1. By supporting with columns and reserving holes, the self-weight of the prefabricated component is greatly reduced, the difficulty of transportation and installation is reduced, and the pressure on the foundation bearing is also reduced.
[0031] 2. By arranging columns at the junction of the beams, the risk of stress concentration of the overall structure is reduced, cracks and deformation of the board due to self-weight or long-term use are avoided, and the service life is prolonged.
[0032] 3. The upper concrete is made of pervious concrete material, combined with the side reserved drainage holes, so that the sidewalk board can quickly drain the surface water in rainy days, and the anti-skid performance of the sidewalk is improved.
[0033] 4. The curbstone, blind area and other functional modules are integrated in one prefabricated component, avoiding the complicated process of assembling multiple components in traditional construction, and improving the construction efficiency.
[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although in the foregoing embodiments are described in detail, for those skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement.
