[0026] The utility model will be further described in detail below in combination with specific embodiments, so that those skilled in the art can more clearly understand the utility model.

[0027] It should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection" and "connection" should be broadly understood, for example, it can be fixedly connected, it can also be detachably connected, and it can also be an integrally formed structure. For ordinary skilled in the art, the specific meaning of such terms in this patent can be understood according to the specific situation.

[0028] Example 1

[0029] Referring to Figure 1 , the embodiment provides a hole pre-burying mold of a concrete floor, which comprises:

[0030] The sleeve 1 is provided with a connecting seat 2 on the side wall, the connecting seat 2 is used for connecting with the template 3, and the outer side of the sleeve 1 is provided with a water stop ring 4.

[0031] Among them, the sleeve 1 can be a PVC sleeve, and its length can be designed according to the thickness of the floor. The connecting seat 2 can be directly connected with the template 3 through bolts. The connecting seat 2 can also be fixed with the template 3 by adhesion. It should be noted that, since the template 3 is usually coated with a release agent (after the concrete pouring is completed, the template 3 can be quickly disassembled), therefore, the connecting seat 2 needs to be adhesively connected with the template 3 before the release agent is applied, so that the connecting seat 2 and the template 3 can be stably connected.

[0032] Based on the above structure, the hole pre-burying mold provided by the embodiment can set the sleeve 1 on the template 3 through the connecting seat 2 before pouring the concrete, then pour the concrete, and after pouring the concrete, the template 3 is removed, so that the drain hole can be reserved on the concrete floor 14. Among them, the connecting seat 2 can ensure the stability of the sleeve 1 during pouring, avoid the deviation of the sleeve 1, and improve the construction accuracy. After pouring, the water stop ring 4 is embedded in the surrounding concrete, which can improve the sealing performance of the sleeve 1 and the surrounding concrete, and further improve the anti-seepage performance of the floor.

[0033] In the embodiment, the outer side of the sleeve 1 is provided with a base 12, and the connecting seat 2 is arranged on the base 12.

[0034] For example, referring to Figure 2The bottom end of the outer side wall of the sleeve pipe 1 is coaxially and fixedly sleeved with a base 12, and the side wall of the base 12 is provided with a connecting seat 2. After the connecting seat 2 is connected and fixed with the formwork 3, the stability of the sleeve pipe 1 can be improved.

[0035] Four connecting seats 2 are uniformly and circumferentially arranged on the side wall of the base 12.

[0036] For example, referring to Figure 2 One connecting seat 2 is arranged on each of the front, back, left and right of the base 12, so that the effect of the connecting seat 2 on the sleeve pipe 1 is more uniform and stable.

[0037] The hole pre-burying mold provided in the embodiment further comprises a reinforcing rib 13, and the reinforcing rib 13 is connected with the base 12 and the sleeve pipe 1.

[0038] For example, referring to Figure 2 Four reinforcing ribs 13 are uniformly and circumferentially arranged on the side wall of the sleeve pipe 1, and the reinforcing ribs 13 can improve the stability of the base 12 and the sleeve pipe 1, so as to avoid that the sleeve pipe 1 is separated from the base 12 due to extrusion of the concrete during the concrete pouring process.

[0039] Two water stop rings 4 are arranged on the outer side of the sleeve pipe 1 in an axially spaced manner.

[0040] For example, referring to Figures 1-2 The two water stop rings 4 are coaxially and fixedly sleeved on the outer side of the sleeve pipe 1, and the two water stop rings 4 are arranged in a high-low manner. After the concrete pouring is completed, the two water stop rings 4 are embedded in the surrounding concrete, so as to play a double waterproof role and further improve the anti-seepage performance of the floor.

[0041] The connecting seat 2, the base 12, the sleeve pipe 1, the reinforcing rib 13 and the water stop ring 4 can be an integrated structure.

[0042] Embodiment 2

[0043] For example, referring to Figure 1 The connecting seat 2 can be directly connected with the formwork 3 through bolts, but after the concrete pouring is completed, the formwork 3 is removed, at this time, the bolts are still left in the connecting seat 2, a large force is required to take out the bolts, and the structure of the connecting seat 2 and even the structure of the sleeve pipe 1 will be damaged.

[0044] In order to avoid the above problems, in the embodiment, a blind hole 5 is arranged on the bottom surface of the connecting seat 2, and a threaded hole 6 corresponding to the blind hole 5 is arranged on the formwork 3.

[0045] For example, referring to Figure 3 Four connecting seats 2 are uniformly and circumferentially arranged on the side wall of the sleeve pipe 1, and the bottom surface of the connecting seat 2 is flush with the bottom surface of the sleeve pipe 1. Four threaded holes 6 are arranged on the formwork 3 in a penetrating manner, and the four threaded holes 6 correspond to the four blind holes 5 one by one.

[0046] The hole pre-buried mold provided by the embodiment further comprises a temporary fixing bolt 7, the top end of the temporary fixing bolt 7 extends into the blind hole 5 through the screw hole 6, and the temporary fixing bolt 7 is screwed with the screw hole 6.

[0047] For example, referring to Figure 3 During construction, the temporary fixing bolt 7 is passed through the screw hole 6, so that the top end of the temporary fixing bolt 7 extends above the formwork 3. Then the sleeve pipe 1 can be directly placed on the formwork 3 at the designed position, so that the blind hole 5 at the bottom surface of the connecting seat 2 is sleeved on the top end of the temporary fixing bolt 7, the temporary fixing bolt 7 can limit the connecting seat 2, and then limit the sleeve pipe 1, so as to prevent the sleeve pipe 1 from slipping and deviating, and the operation is simple and convenient.

[0048] In order to further improve the stability of the sleeve pipe 1, the blind hole 5 can be provided with an internal thread, so that during construction, the sleeve pipe 1 needs to be placed on the formwork 3 at the designed position in advance, at this time, the screw hole 6 is aligned with the corresponding blind hole 5, and then the temporary fixing bolt 7 is screwed in the downward direction of the formwork 3, so that the top end of the temporary fixing bolt 7 is screwed with the internal thread in the blind hole 5, that is, the connecting seat 2 and the formwork 3 can be locked and fixed, and the stability is higher.

[0049] Embodiment 3

[0050] When the actual used pipeline diameter is smaller than the sleeve pipe 1, there can be a large gap between the sleeve pipe 1 and the pipeline, which can cause the cold air in the cold storage to leak. In order to avoid the above problem, on the basis of embodiment 1, in the embodiment, a sealing element is arranged on the sleeve pipe 1.

[0051] The sealing element can play a sealing role and improve the sealing performance between the sleeve pipe 1 and the pipeline.

[0052] The sealing element can comprise a spigot 8 and a mounting ring 9, the mounting ring 9 is arranged at the top end of the spigot 8, the spigot 8 is matched with the sleeve pipe 1, the spigot 8 is clamped in the sleeve pipe 1, the mounting ring 9 is communicated with the spigot 8, and a sealing gasket 10 is arranged on the inner side of the mounting ring 9.

[0053] For example, referring to Figures 4-5 The spigot 8 is clamped in the sleeve pipe 1, the mounting ring 9 can be overlapped on the top end of the sleeve pipe 1, and the sealing gasket 10 is arranged on the inner side of the mounting ring 9. In this way, the pipeline can pass through the inner side of the mounting ring 9 downward, then pass through the inner side of the spigot 8, then pass through the inner side of the sleeve pipe 1, and finally enter the floor below. At this time, the sealing gasket 10 can be pressed on the outer side of the pipeline, and can play an auxiliary sealing role, effectively reducing the gap.

[0054] A sealing ring 11 is arranged between the spigot 8 and the sleeve pipe 1.

[0055] For example, referring to Figures 4-5The sealing ring 11 can improve the sealing performance between the insertion tube 8 and the sleeve 1. The insertion tube 8 can be inserted into the inside of the sleeve 1 from top to bottom, and then clamped by the sealing ring 11, so that the installation of the sealing member is completed. Conversely, the insertion tube 8 is lifted upward, and the sealing member can be removed. The installation and disassembly processes are very simple.

[0056] It should be noted that the sleeve 1 needs to be flushed clean before the concrete is poured during construction, and the top end is sealed with adhesive tape. The sealing member in the application can be selectively installed according to the actual situation at a later stage, and is flexible to use and widely applicable.
