[0023] The following is a further detailed description of a water pipe well post-cast floor slab closure system provided by the utility model in combination with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer in combination with the following description. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0024] like Figure 1 and Figure 2 As shown, a water pipe well post-cast floor slab closing system provided in this embodiment includes an anchor plate 2, a main beam 3, a secondary beam 4, a steel plate 5, a steel casing 6 and a post-cast floor slab 7.

[0025] Combination Figures 1 to 6 As shown, a concrete beam 1 is arranged on the building structure of the adjacent parts around the post-cast floor slab, and an anchor plate 2 is pre-embedded in the concrete beam 1, or a chemical bolt is used to post-install the anchor plate 2. As an example, the anchor plate 2 is fixed in the concrete beam 1 by a plurality of anchor bars 22. The thickness of the anchor plate 2 is 10 mm, the length is 330 mm, and the width is 170 mm. Four anchor bars 22 are arranged on one side of the anchor plate 2, and the anchor bars 22 are threaded steel bars with a diameter of 12 mm. Further, a welding hole 21 is arranged at the connection between the anchor plate 2 and the anchor bar 22. The welding hole 21 is arranged with a groove, for example, the welding hole 21 is arranged in a truncated cone shape, and one end of the anchor bar is inserted into the anchor plate from the end with a smaller diameter of the welding hole 21. The insertion length is less than the thickness of the anchor plate, and the anchor bar is welded and fixed in the gap between the anchor bar and the anchor plate and at the end of the anchor bar. The weld 23 at the end with a larger diameter of the welding hole 21 is flush with the surface of the anchor plate 2, and the weld 23 at the end with a smaller diameter of the welding hole 21 is in an arc shape.

[0026] Two main beams 3 are arranged horizontally at intervals and both ends are fixedly connected to the anchor plate 2 respectively. A number of secondary beams 4 are arranged between the two main beams 3, and the steel plate 5 is arranged on the secondary beam 4. Of course, the number of main beams is determined according to the width of the post-cast floor slab. When the width is wider, more main beams can be arranged. As an example, No. 14 I-beams are selected as the main beams and No. 12 I-beams are selected as the secondary beams. The two ends of the I-beam main beam are welded to the steel plate of the anchor plate, and the two ends of the I-beam secondary beam are welded to the main beam. The top of the secondary beam is flush with the top of the main beam, and a 5mm thick steel plate is fully laid and welded on the I-beam beam. According to the specific size of the pipe well floor slab, the secondary beam can also be made of channel steel or no secondary beam can be set.

[0027] The bottom of the steel casing 6 is fixedly connected to the steel plate 5. A through hole is provided on the steel plate 5 at a position corresponding to the steel casing 6. The through hole is connected to the inside of the steel casing. Preferably, the inner diameter of the through hole is consistent with the inner diameter of the steel casing.

[0028] The post-cast floor 7 is arranged between the steel casing 6 above the steel plate 5 and the concrete beam 1 of the building structure, and the top of the steel casing is 2cm to 5cm higher than the upper surface of the post-cast floor. As an example, a bidirectional Φ8@150 steel mesh is arranged in the post-cast floor, and the steel mesh is welded and fixed to the steel casing. The thickness of the post-cast floor is 120mm, and the height of the steel casing is 140mm. The steel casing is higher than the thickness of the post-cast floor, and a cover plate can be laid on the top of the high casing to prevent concrete or other things from blocking the steel casing.

[0029] During the construction process, the anchor plate 2 is constructed first to fix the anchor plate 2 to the concrete beam 1, and then the main beam 3 and the secondary beam 4 are installed, and then the steel plate 5 is laid. According to the position of the steel casing 6, through holes are pre-arranged on the steel plate 5, and the steel casing 6 is welded. Then the steel mesh of the post-cast floor slab is laid. The steel bars at the position disconnected by the steel casing 6 can be welded and fixed to the outer wall of the steel casing, or bypass the steel sleeve, and then concrete of the designed thickness is poured in the area enclosed by the steel plate, steel sleeve and concrete beam.

[0030] The water pipe well post-cast floor slab closing system provided in this embodiment uses the steel plate as the bottom formwork when pouring concrete of the post-cast floor slab, and the main beam, secondary beam and anchor plate provide support and transfer the load to the surrounding concrete beams, thereby improving construction safety. The steel sleeve is pre-welded and fixed to the steel plate, thereby improving construction efficiency. After the construction of the post-cast floor slab is completed, the main beam, secondary beam and anchor plate can be used as a permanent structure, thereby improving the safety of the post-cast floor slab.

[0031] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
