Description

Technical Field

[0001] The utility model relates to the technical field of drainage engineering, in particular to a drainage trough with an anti-floating pressure plate. Background Art

[0002] A gutter is a facility or device used to collect, divert and discharge liquid or wastewater. It is usually made of durable materials (such as plastic, stainless steel) and installed on the ground, wall or underground in buildings, roads, industrial facilities, stations, kitchens, bathrooms, farmland and other places.

[0003] There are two construction schemes for the installation of existing plastic drain gutters: load-bearing and non-load-bearing. The construction scheme when load-bearing is required is to first cast and level the bottom of the ditch, and then put the drain ditch into the ditch after the cast-in-place bottom of the ditch hardens, and then cast the two sides of the ditch to the height of the ground with concrete. In this process, because concrete will generate buoyancy when cast-in-place, the drain ditch is extremely unstable during the process of casting on both sides, and will swing, shift and float. Another non-load-bearing construction scheme is to directly install the drain ditch on the excavated soil bottom of the ditch, and directly backfill both sides with fine soil to the ground height. The backfill soil has many small gaps. When it rains, rainwater seeps from the gaps in the backfill soil to the bottom of the drain ditch to generate buoyancy, causing the drain ditch to float. Therefore, this application provides a drain ditch with an anti-floating pressure plate to meet the needs. Utility Model Content

[0004] The purpose of the present application is to provide a drainage trough with an anti-floating pressure plate, so as to solve the technical problem that the existing plastic drainage troughs are prone to swinging, shifting and floating.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a drainage trough with an anti-floating pressure plate, comprising a drainage trough with a plurality of supporting protrusions at the bottom, two anti-floating pressure plates are symmetrically arranged on two adjacent supporting protrusions, the two anti-floating pressure plates are fixedly connected to the corresponding supporting protrusions by bolts, two first mounting holes and one cement nail mounting hole are arranged on the two anti-floating pressure plates, a second mounting hole adapted to the first mounting hole is arranged at the bottom corresponding to the supporting protrusion, and the diameter of the cement nail mounting hole is smaller than the diameter of the knocking end of the cement nail.

[0006] As a preferred implementation manner in this embodiment, a limiting strip adapted to the supporting protrusion is provided at the upper ends of the two anti-floating pressure plates and located at the first mounting hole.

[0007] As a preferred implementation manner in this embodiment, both ends of the supporting protrusion are provided with notches adapted to the supporting protrusion, and the height of the notches is consistent with the thickness of the anti-floating pressure plate.

[0008] As a preferred implementation manner in this embodiment, an elastic buffer pad is arranged above the cement nail installation hole, and a metal ring is bonded to the upper end of the elastic buffer pad, and a through hole with the same size as the cement nail installation hole and the axis located on the same straight line is arranged at the axis of the metal ring and the elastic buffer pad.

[0009] As a preferred implementation mode in this embodiment, the drainage trough includes a bottom plate, two corrugated plates, two L-shaped supporting steps and a plurality of drain cover plates placed on the two L-shaped supporting steps, the two corrugated plates are respectively arranged on both sides of the bottom plate, the two L-shaped supporting steps are respectively installed on the corresponding corrugated plates, and a plurality of T-shaped blocks are arranged at the junction of the corrugated plates and the L-shaped supporting steps.

[0010] In summary, the technical effects and advantages of the utility model are:

[0011] The utility model has a reasonable structure, and anti-floating pressure plates are arranged on both sides of the bottom of the drainage trough. When there is load-bearing installation, cement nails are nailed into the concrete at the bottom of the ditch through the cement installation holes arranged on the anti-floating pressure plates, so as to fix the drainage trough and prevent it from floating. Then, concrete is cast on both sides of the drainage trough to the height of the ground, which can effectively prevent the drainage trough from swinging, shifting and floating during the casting process on both sides. When there is no load-bearing installation, the drainage trough is placed on the excavated ditch bottom and fine soil is directly backfilled to the height of both sides of the drainage ditch to the ground. Since the anti-floating pressure plate at the bottom of the drainage trough has a certain area, the weight of the backfill soil acts on the anti-floating pressure plate to exert reverse pressure, which can prevent the buoyancy of rainwater from causing the drainage trough to float.

[0012] In the utility model, a limit strip is provided, and the lower ends of the supporting protrusions are inserted into the limit cavity of the limit strip, so that the anti-floating pressure plate can be limited, and the anti-floating pressure plate can be prevented from rotating relative to the drainage groove when the bolts are rotated and fixed, which facilitates the installation of the anti-floating pressure plate and the drainage groove;

[0013] In the utility model, an elastic buffer pad and a metal ring are provided. The elastic buffer pad can buffer the collision between the hammer head and the anti-floating pressure plate caused by operating errors, thereby reducing damage to the anti-floating pressure plate. At the same time, the provision of the metal ring can prevent the elastic buffer pad from being hammered and has a protective effect on the elastic buffer pad. The lower part of the spindle striking head will contact the upper end of the metal ring and cooperate with the elastic buffer pad to ensure a stable fixing effect of the drain trough without causing significant damage to the anti-floating pressure plate.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: Reference Figure 1 A drainage trough with an anti-floating pressure plate shown in the figure comprises a drainage trough 1 with a plurality of supporting protrusions 2 at the bottom, two anti-floating pressure plates 3 are symmetrically arranged on two adjacent supporting protrusions 2, and the two anti-floating pressure plates 3 are fixedly connected to the corresponding supporting protrusions 2 by bolts, and two first mounting holes 5 and a cement nail mounting hole 4 are arranged on the two anti-floating pressure plates 3, and a second mounting hole 8 adapted to the first mounting hole 5 is arranged at the bottom corresponding to the supporting protrusion 2, and the diameter of the cement nail mounting hole 4 is smaller than the diameter of the knocking end of the cement nail.

[0022] The anti-floating pressure plate 3 is fixed to the drainage ditch 1 by means of the cooperation of bolts, the first mounting holes 5 and the second mounting holes 8. When there is load-bearing installation, the bottom of the ditch is first cast in place and leveled. After the cast-in-place bottom of the ditch is hardened, the drainage ditch is placed in it. Cement nails are nailed into the concrete at the bottom of the ditch through the cement mounting holes provided on the anti-floating pressure plate 2 to fix the drainage ditch 1 and prevent it from floating. Then, concrete is cast in place on both sides of the drainage ditch to the height of the ground, which can effectively prevent the drainage ditch 1 from swinging, shifting and floating during the casting process on both sides. When there is no load-bearing installation, the drainage ditch 1 with the anti-floating pressure plate 3 is placed on the excavated bottom of the ditch, and then fine soil is directly backfilled on both sides of the drainage ditch to the height of the ground. Since the anti-floating pressure plate 3 at the bottom of the drainage ditch 1 has a certain area, the weight of the backfill soil acts on the anti-floating pressure plate 3 to exert reverse pressure, which can prevent the buoyancy of rainwater from causing the drainage ditch 1 to float.

[0023] As a preferred implementation in this embodiment, as shown in FIG3 , a limiting strip 6 adapted to the supporting protrusion 2 is provided at the upper ends of the two anti-floating pressure plates 3 and located at the first mounting hole 5 .

[0024] The lower ends of the supporting protrusions are all inserted into the limiting cavities of the limiting strips 6, which can limit the anti-floating pressure plate 3 and prevent the anti-floating pressure plate 3 from rotating relative to the drainage trough 1 during the bolt rotation and fixing installation, thereby facilitating the installation of the anti-floating pressure plate 3 and the drainage trough 1.

[0025] It should be noted that the limiting strip 6 can be set to an Ω-shaped structure or other structures.

[0026] As a preferred implementation in this embodiment, Figure 2 As shown, both ends of the support protrusion 2 are provided with notches 7 adapted to the support protrusion 2 , and the height of the notches 7 is consistent with the thickness of the anti-floating pressure plate 3 .

[0027] Ensuring that the lower end surface of the anti-floating pressure plate 3 and the lower end surface of the supporting protrusion 2 after installation are on the same plane can effectively reduce the possibility of local stress concentration and avoid large stress concentration at the supporting position, thereby reducing the stress risk of the anti-floating pressure plate 3 or the supporting protrusion 2 and extending its service life.

[0028] As a preferred implementation in this embodiment, Figure 4 As shown, an elastic buffer pad 9 is arranged above the cement nail installation hole 4, and a metal ring 10 is bonded to the upper end of the elastic buffer pad 9, and a through hole with the same size as the cement nail installation hole 4 and the axis located on the same straight line is arranged at the axis of the metal ring 10 and the elastic buffer pad 9.

[0029] Since the drain ditch 1 is made of plastic material, and the cement nail needs to be driven into cement with a hammer head, in order to prevent the hammer head from directly colliding with the anti-floating pressure plate 2 due to an error in the process of hammering the nail (which may easily cause the anti-floating pressure plate to crack or be directly damaged, thereby reducing the fixing effect of the drain ditch 1) and also prevent the nail head from being over-extruded with the anti-floating pressure plate 2 (excessive extrusion may easily cause the anti-floating pressure plate 3 to crack, thereby reducing the fixing effect of the drain ditch 1), an elastic buffer pad 9 and a metal ring 10 are provided. The elastic buffer pad 9 can buffer the collision between the hammer head and the anti-floating pressure plate 2 due to operational errors. The collision between the floating pressure plates 2 (the elastic buffer pad 9 can expand the covering area of ​​the anti-floating pressure plate 3, and even if there is an operational error, the hammer head will not directly contact the anti-floating pressure plate 3, and the hammer head will contact the metal ring 10) reduces the damage to the anti-floating pressure plate 3. At the same time, the setting of the metal ring 10 can prevent the elastic buffer pad 9 from being hammered and has a protective effect on the elastic buffer pad 9. The lower part of the spindle striking head will contact the upper end of the metal ring 10, and cooperate with the elastic buffer pad 9, so that the drainage trough 1 can be stably fixed without causing major damage to the anti-floating pressure plate 3.

[0030] As a preferred implementation mode in this embodiment, the drainage trough 1 includes a base plate 101, two corrugated plates 102, two L-shaped supporting steps 103 and a plurality of drain covers 104 placed on the two L-shaped supporting steps 103. The two corrugated plates 102 are respectively arranged on both sides of the base plate 101, and the two L-shaped supporting steps 103 are respectively installed on the corresponding corrugated plates 102. A plurality of T-shaped blocks 105 are arranged at the joints between the corrugated plates 102 and the L-shaped supporting steps 103.

[0031] The uneven surface of the corrugated plate 102 can enhance the structural strength of the drainage trough 1. The provision of the T-shaped block 105 can enhance the structural strength of the joint between the L-shaped supporting step 103 and the corrugated plate 102. At the same time, the T-shaped block 105 also acts as a hook. Because the material of the drainage trough 1 is generally plastic, it has no adhesion to the concrete (when pouring on both sides). Over time, the two sides of the drainage trough 1 will be separated from the concrete on both sides to form a gap. The T-shaped block 105 can be used to embed the drainage trough 1 in the concrete on both sides to avoid the separation of the two sides of the drainage trough 1 from the concrete on both sides to form a gap, which is beneficial to the stability of the drainage trough 1.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
