Description

Technical Field

[0001] The utility model belongs to the technical field of building drainage, and specifically relates to a ground drainage structure for prefabricated buildings. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to a factory. Building components and fittings (such as floor slabs, wall panels, balconies, etc.) are processed and manufactured in the factory and transported to the building construction site, and then assembled and installed on-site through reliable connection methods.

[0003] Referring to the publication number CN218405672U, a ground drainage structure for prefabricated buildings is disclosed, which includes a support frame, a first floor and a second floor. In this application, the size of the drainage hole is determined by the distance between the opposite ends of the first floor and the second floor, and can be adjusted according to actual conditions; and the first floor and the second floor have been produced and manufactured in the factory, and the staff can assemble them on-site, which improves the on-site installation efficiency of the drainage structure.

[0004] Based on the above technical findings, the above method realizes drainage through the gap formed between the first floor and the second floor. When the distance is too large, although the drainage effect can be guaranteed, foreign objects such as hair or others are likely to fall into the drainage ditch along the gap. Although the filtering operation can be realized through the filter screen, since the drainage ditch is located inside the first floor and the second floor, it is easy to be blocked after long-term use, affecting the drainage effect; secondly, the first floor and the second floor are in a flat state, and water is not easy to accumulate on the floor surface, and long-term accumulation is likely to erode the floor and affect its use.

[0005] In view of this, a ground drainage structure for prefabricated buildings is proposed. Content of the Utility Model

Specific implementation mode

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the following further details the utility model in combination with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0024] Refer to Figure 1-2 , an assembled building floor drainage structure, including a support frame 3 pre - installed on the indoor wall, the upper end of the support frame 3 is provided with a first floor 2 and a second floor 11, a drainage hole is formed by enclosing between the first floor 2 and the second floor 11, and a filtering mechanism is detachably installed in the drainage hole. The drainage hole is formed by assembling and splicing the first floor 2 and the second floor 11, thereby improving the on - site installation efficiency of the drainage structure.

[0025] Furthermore, the filtering mechanism includes an outer enclosure 9 and a filter screen 10. The outer enclosure 9 has a hollow water guide cavity, and the filter screen 10 is detachably installed in the water guide cavity for filtering the discharged water. A filtering mechanism is reserved between the first floor 2 and the second floor 11. Through the filter screen 10, substances such as hair or foreign objects can be filtered on the surface of the outer enclosure 9, which is convenient for the user to perform maintenance operations. The rainwater can drain along the filter screen 10 without affecting the drainage effect. At the same time, important items such as rings can also be isolated on the outer enclosure 9, thus avoiding the loss of important items.

[0026] Furthermore, anti - slip bricks 4 are pasted on the upper end surfaces of the first floor 2 and the second floor 11, and the anti - slip bricks 4 are adjusted in angle corresponding to the first floor 2 and the second floor 11.

[0027] Among them, the outer frame of the filter screen 10 can be fixed on the outer enclosure 9 by screws or buckles, and the filter screen 10 can also be removed for cleaning or replacement operations.

[0028] Furthermore, both the first floor 2 and the second floor 11 are inclined towards the filtering mechanism, and the inclination angles of the first floor 2 and the second floor 11 are 1° to 3°. A water guiding slope is provided on the floor, and water can drain along the slope, thereby avoiding the phenomenon of the floor getting damp due to water accumulation.

[0029] Furthermore, grooves are reserved at the upper parts of the opposite ends of the first floor 2 and the second floor 11. Edging strips 7 are fixed to the opposite end faces of the first floor 2 and the second floor 11. A limiting part abutting against the edging strip 7 is provided on the outer peripheral surface of the outer housing 9. A plurality of positioning blocks 901 are provided along the length direction at the bottom end of the limiting part of the outer housing 9. The positioning blocks 901 are recessed inward to form limiting grooves. The upper end face of the edging strip 7 protrudes to form limiting protrusions correspondingly inserted into the limiting grooves. Through the cooperation of the limiting protrusions and the limiting grooves, the position of the filtering mechanism on the edging strip 7 can be assisted in positioning, thereby ensuring the installation accuracy of the filtering mechanism and avoiding the phenomenon of the filtering mechanism shifting or tilting during use.

[0030] Among them, the edging strip 7 is made of stainless steel, but this is not limited here.

[0031] Furthermore, magnets 8 with opposite magnetic polarities are respectively accommodated in the positioning blocks 901 at both ends of the outer housing 9 and the limiting protrusions at both ends of the edging strip 7. The part with the magnet 8 can magnetically fix the filtering mechanism and the edging strip 7 together, thereby ensuring the strength of the combination of the two.

[0032] Furthermore, a drainage ditch 1 is provided directly below the outer housing 9. The upper end of the drainage ditch 1 has an opening, and the bottom of the drainage ditch 1 is communicated with a drain pipe 5. The water discharged through the outer housing 9 can be collected through the drainage ditch 1 and then discharged through the drain pipe 5. Among them, the drain pipe 5 can be connected to an external drainage system (not shown in the figure).

[0033] Furthermore, upper abutting plates abutting against the bottoms of the first floor 2 and the second floor 11 are respectively provided at both ends of the upper end face of the drainage ditch 1. The upper ends of the upper abutting plates protrude upward to form positioning convex surfaces 102. Positioning grooves for the positioning convex surfaces 102 to be inserted into are reserved at the bottom ends of the first floor 2 and the second floor 11. Through the cooperation of the positioning convex surfaces 102 and the positioning grooves, the installation positions of the first floor 2 and the second floor 11 can be assisted in positioning, thereby ensuring the accuracy during overall assembly and eliminating the need for multiple adjustments of the positions of the first floor 2 and the second floor 11.

[0034] Furthermore, a water guiding slope 101 inclined towards the drain pipe 5 is provided on the inner wall at the bottom end of the drainage ditch 1. The slope of the water guiding slope 101 is 25° to 40°. The water guiding slope 101 can guide the water entering the drainage ditch 1 out, avoiding the phenomenon of the water stinking due to long-term accumulation in the drainage ditch 1.

[0035] Furthermore, support angle steels 6 are installed on both sides of the bottom end of the drain ditch 1. The two support angle steels 6 are fixed on the support frame 3 and enclose a support space for supporting the drain ditch 1. The installation position of the drain ditch 1 can be assisted in being defined through the support angle steels 6. The drain ditch 1 and the support angle steels 6 are connected by bolts. During assembly, only by pushing the drain ditch 1 into the support space can the installation position of the drain ditch 1 be assisted in being defined, and the assembly effect is better. At the same time, it can also serve as an auxiliary support part of the drain ditch 1.

[0036] To sum up, a filtering mechanism is reserved between the drain holes. Through the filter net 10, substances such as hair or foreign objects can be filtered on the surface of the outer shell 9, which is convenient for the user to perform maintenance operations. At the same time, rainwater flowing along the filter net 10 into the drain ditch 1 for drainage will not affect the drainage effect. At the same time, a water guiding slope is provided on the floor, and water can flow into the drain ditch 1 along the slope, thereby avoiding the phenomenon of the floor getting damp due to water accumulation.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
