Description

Technical Field

[0001] The utility model relates to the technical field of building apron, in particular to a prefabricated assembled concrete building apron. Background Technique

[0002] An apron refers to a sloping apron made of rubble masonry or cast with concrete around the plinth at the outer perimeter of a building. The function of the apron is to quickly drain the rainwater near the plinth, avoid the rainwater from scouring or penetrating into the foundation, and prevent the foundation from sinking, so as to ensure the firmness and durability of the building. With the development of modern architecture, the apron structure has also formed a precast concrete apron structure, which can meet the construction requirements of prefabricated assembled concrete buildings.

[0003] When the existing prefabricated assembled concrete building apron is in use, there is a lack of a centralized drainage structure on the side of the apron, so that the rainwater is still likely to penetrate into the soil after flowing to the ground through the apron structure, scouring the soil around the foundation, endangering the building foundation. At the same time, when the existing building apron is in use, the drainage joints on the drainage ditch cover plate are open, and the peculiar smell generated by the accumulated water in the drainage ditch is likely to float out and pollute the air. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a prefabricated assembled concrete building apron. Through the arranged precast apron and drainage ditch, the water drained from the apron can enter the drainage ditch for centralized drainage, avoiding the rainwater from penetrating into the soil around the apron and scouring the soil around the foundation, protecting the building foundation, and effectively solving the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a prefabricated assembled concrete building apron, including a precast apron and a drainage ditch, a drainage cover plate is arranged on the upper side of the drainage ditch, drainage joints are arranged at equal intervals on the drainage cover plate, an odor baffle is arranged below the drainage joints, a rotating shaft is arranged on the odor baffle, a flat coil spring is installed on the rotating shaft, and a cavity is arranged inside the precast apron.

[0006] Further, an assembled wall panel is arranged on the side of the precast apron away from the drainage ditch, and a caulking paste is filled in the gap between the assembled wall panel and the precast apron.

[0007] Further, a waterproof strip is arranged on the side surface of the assembled wall panel above the caulking paste, and a rammed sand layer is arranged below the precast apron.

[0008] Further, the precast apron is connected to the assembled wall panel through the caulking paste, and the odor baffle is connected to the drainage cover plate through the flat coil spring and the rotating shaft.

[0009] Further, the drainage cover plate is formed by extrusion molding of ABS plastic, and the center of the rotating shaft is connected to the inner end of the flat coil spring through a card slot.

[0010] Further, the outer end of the flat coil spring is connected to the drainage cover plate through a card slot.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Through the prefabricated water-dispersing layer and drainage ditch provided by the utility model, the water drained on the water-dispersing layer can enter the drainage ditch for centralized drainage, avoiding rainwater from seeping into the soil around the water-dispersing layer and scouring the soil around the foundation, thereby protecting the building foundation.

[0013] 2. Through the drainage cover plate, drainage seam, odor baffle, rotating shaft and flat coil spring provided by the utility model, the rotating shaft on the odor baffle is rotationally connected to the drainage cover plate through the flat coil spring, and the odor baffle can be automatically closed under the spring force of the flat coil spring to avoid odor dispersion.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer toFigures 1-4 , this embodiment provides a technical solution: a prefabricated concrete building apron, including a prefabricated apron 2 and a drainage ditch 5. A drainage cover plate 6 is provided on the upper side of the drainage ditch 5. Drainage slots 9 are arranged at equal intervals on the drainage cover plate 6. An odor baffle 8 is arranged below the drainage slots 9. A rotating shaft 13 is arranged on the odor baffle 8. A flat coil spring 12 is installed on the rotating shaft 13. A cavity 3 is arranged inside the prefabricated apron 2.

[0021] As Figures 1-4 shown, rainwater flows into the drainage ditch 5 through the prefabricated apron 2. The drainage cover plate 6 can filter sundries. The rainwater enters the upper side of the odor baffle 8 of the drainage slot 9. The odor baffle 8 rotates downward under the action of the weight of the rainwater, and then the rainwater enters the drainage ditch 5. When the rain stops, the odor baffle 8 can rotate upward and close under the action of the flat coil spring 12, thereby blocking the drainage slot 9, avoiding the odor of accumulated water from spreading out and polluting the air, making the rainwater discharged concentratedly, and avoiding the rainwater from seeping into the soil along the edge position of the prefabricated apron 2 and scouring the soil layer around the building foundation. Thus, the foundation of the building can be protected. The waterproof strip 10 can provide waterproof protection for the caulking paste 4.

[0022] An assembled wall panel 1 is arranged on one side of the prefabricated apron 2 away from the drainage ditch 5. The gap between the assembled wall panel 1 and the prefabricated apron 2 is filled with a caulking paste 4. The caulking paste 4 can seal the gap between the prefabricated apron 2 and the assembled wall panel 1.

[0023] A waterproof strip 10 is arranged on the side of the assembled wall panel 1 above the caulking paste 4. A rammed sand layer 7 is arranged below the prefabricated apron 2. The rammed sand layer 7 stably supports the prefabricated apron 2. The waterproof strip 10 can provide rain protection for the position of the caulking paste 4.

[0024] The prefabricated apron 2 and the assembled wall panel 1 are connected by the caulking paste 4. The odor baffle 8 and the drainage cover plate 6 are connected by the flat coil spring 12 and the rotating shaft 13.

[0025] The drainage cover plate 6 is formed by extrusion molding of ABS plastic. The center of the rotating shaft 13 is connected to the inner end of the flat coil spring 12 through a card slot.

[0026] The outer end of the flat coil spring 12 is connected to the drainage cover plate 6 through a card slot.

[0027] The working principle of the prefabricated concrete building apron provided by the present utility model is as follows: As Figures 1-4As shown in the figure, rainwater flows into the drainage ditch 5 through the precast apron 2. The drainage cover plate 6 can filter sundries. The rainwater enters the upper side of the odor baffle 8 of the drainage joint 9. Under the action of the weight of the rainwater, the odor baffle 8 rotates downward, so that the rainwater enters the drainage ditch 5. When the rain stops, the odor baffle 8 can rotate upward and close under the action of the flat coil spring 12, thus blocking the drainage joint 9 to prevent the odor of the accumulated water from drifting out and polluting the air, enabling the rainwater to be discharged centrally, and preventing the rainwater from infiltrating into the soil along the edge of the precast apron 2 and scouring the soil layer around the building foundation. Therefore, the foundation of the building can be protected. The waterproof strip 10 can provide waterproof protection for the caulking paste 4.

[0028] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
