[0031] The present application will be further described below in combination with the drawings and specific embodiments.

[0032] The present application provides a floor slab reserved hole blocking device and a construction method thereof, which solves the water leakage problem caused by exposing the gap between the bolt and the concrete on the floor slab when blocking the reserved hole, and the problem that the cost cannot be reduced caused by cutting the excess bolt. The present application is realized by adopting the detachable first connecting piece and the second connecting piece to pour concrete into the reserved hole twice, after the fixed piece is used to block the reserved hole of the floor slab with the first connecting piece and the second connecting piece, the first connecting piece and the blocking plate are firmly fixed in the reserved hole by pouring concrete into the reserved hole, and after the fixed piece is detached with the second connecting piece, the second time of pouring concrete into the reserved hole, the connecting piece is not exposed on the upper surface of the concrete poured at the reserved hole, and the connecting piece can be detachably and circularly used.

[0033] Referring to Figure 1 , a first time pouring section view of the floor reserved hole sealing device and sealing method thereof is shown. Referring to Figure 2 , a sealing section view of the floor reserved hole sealing device and sealing method thereof is shown. The floor reserved hole sealing device will be described below in conjunction with Figure 1 and Figure 2 .

[0034] As shown in Figure 1 and Figure 2 , the floor reserved hole sealing device is used for sealing the reserved hole on the floor, comprising a first connecting piece 21, a second connecting piece 22, a sealing plate 23 and a fixing piece 24. The sealing plate 23 is used for sealing the bottom of the reserved hole, the first connecting piece 21 is connected with the sealing plate 23 and can be placed in the reserved hole, the second connecting piece 22 is detachably linked with the first connecting piece 21, the second connecting piece 22 has a part located outside the reserved hole, the fixing piece 24 is sleeved on the second connecting piece 22 and can be moved up and down to adjust along the second connecting piece 22, the fixing piece 24 can be moved to abut against the upper surface of the floor, so that the sealing plate 23 is tightly attached to the bottom of the reserved hole. Specifically, one end of the second connecting piece 22 extends out of the upper surface of the floor, the other end is detachably linked with the first connecting piece 21, the end of the first connecting piece 21 away from the second connecting piece 22 is connected with the sealing plate 23, the whole structure is supported on the floor by the fixing piece, and the sealing plate 23 is fixed in the reserved hole. When pouring concrete, the first connecting piece 21 and the second connecting piece 22 can pull the sealing plate 23 under the action of the fixing piece 24, so as to prevent the sealing plate 23 from being deviated by the pressure of the concrete and improve the stability of the structure.

[0035] Further, the sealing plate 23 is fixedly connected to the end of the first connecting piece 21 close to the lower bottom surface of the floor, so as to seal the hole opening of the reserved hole located on the lower surface of the floor, avoiding leakage of concrete during pouring. Preferably, the distance between the sealing plate 23 and the upper surface of the floor is measured and adjusted, so that the lower surface of the sealing plate 23 is located at the position flush with the lower surface of the floor when the sealing plate 23 is fixed, preventing the sealing plate 23 from protruding out of the lower surface of the floor, reducing the friction between the sealing plate 23 and the inner wall of the reserved hole, and avoiding that the sealing plate 23 excessively protrudes in the reserved hole to form a depression on the lower surface of the floor, affecting the integrity and appearance of the sealing structure.

[0036] The fixing piece 24 is connected to the end of the second connecting piece 22 extending out of the reserved hole, and the fixing piece 24 abuts against the upper surface of the floor to fix the second connecting piece 22 and the first connecting piece 21 in the reserved hole, so as to fix the lower surface of the sealing plate 23 at the position flush with the lower surface of the floor, providing conditions for subsequent pouring of concrete.

[0037] In a preferred embodiment, as shown in Figure 1As shown, the sealing plate 23 is made of elastic material and has elasticity. The diameter of the sealing plate 23 is larger than the inner diameter of the reserved hole, so that when the sealing plate 23 is stuck in the reserved hole, it generates greater friction with the inner wall of the floor slab, ensuring the firm installation of the sealing plate 23.

[0038] In a preferred embodiment, the sealing plate 23 is made of rubber.

[0039] Furthermore, such as Figure 2 The diagram shows a cross-sectional view after sealing in the pre-reserved hole sealing device and sealing method of the present invention. Preferably, the second connector 22 and the first connector 21 are connected together by a threaded sleeve 25. Before pouring concrete, the sealing plate 23, the second connector 22 and the first connector 21 are fixed to the floor slab by the fixing member 24. Concrete is poured into the pre-reserved hole to submerge the first connector 21 up to the position of the threaded sleeve 25, exposing the second connector 22. After the concrete solidifies, the fixing member 24 is removed, the second connector 22 is unscrewed, and concrete is poured into the pre-reserved hole a second time to seal the pre-reserved hole. When pouring concrete into the pre-reserved hole for the second time, space is reserved for pouring a waterproof layer 27. After the second pour of concrete solidifies, a waterproof layer 27 is finally laid to enhance the overall waterproof performance of the structure and avoid cutting bolts, thus increasing the utilization rate of bolts.

[0040] In a preferred embodiment, during the second pour, the concrete is poured to a depth of 1 cm from the top surface of the floor slab. This 1 cm space is reserved for filling with asphalt sealant to enhance waterproofing performance.

[0041] Furthermore, such as Figure 1 As shown, the fastener 24 is threadedly connected to the second connector 22, and the fastener 24 has a supporting portion that can abut against the upper surface of the floor slab to fix the fastener 24 to the floor slab, thereby fixing the second connector 22, the first connector 21 and the sealing plate 23 to the floor slab.

[0042] In a preferred embodiment, a pad 26 is provided under the fastener 24 to improve the tightness of the connection between the fastener 24 and the floor slab.

[0043] Furthermore, the first connector 21 is fixed to the sealing plate 23 by welding, which strengthens the fixing strength.

[0044] See Figure 3 and Figure 4 The diagram shows the structure after the first pour and the structure after sealing in the floor slab pre-reserved hole sealing device and sealing method of the present invention.

[0045] The following is combined with Figure 3 and Figure 4 The sealing method for the pre-reserved hole sealing device in the floor slab is explained.

[0046] S1. Extend the blocking plate 23 into the bottom of the reserved hole, and block the bottom of the reserved hole. Preferably, by measuring and adjusting the distance between the blocking plate 23 and the upper surface of the floor slab, the lower surface of the blocking plate 23 is at the same level as the lower surface of the floor slab when the blocking plate 23 is fixed, so as to block the reserved hole to prevent slurry leakage during pouring.

[0047] S2. Threadedly connect the fixing member 24 to the second connecting member 22 exposed to one end of the reserved hole, and move the adjusting fixing member 24 downward to allow the fixing member 24 to abut against the upper surface of the floor slab, and fix the blocking plate 23, the second connecting member 22 and the first connecting member 21, so that the blocking plate 23 does not shift during subsequent pouring of concrete into the reserved hole, thereby avoiding the risk of slurry leakage.

[0048] S3. Pour the first time of concrete into the reserved hole to cover the first connecting member 21, and lower than the connection between the second connecting member 22 and the first connecting member 21, specifically, lower than the connection between the second connecting member 22 and the threaded sleeve 25, so that the second connecting member 22 is completely exposed to the first poured concrete, so that the second connecting member 22 can be detached after the concrete solidifies.

[0049] S4. After the concrete solidifies, the fixing member 24 is detached, and the second connecting member 22 is screwed off, so that the first connecting member 21 and the second connecting member 22 are separated, thereby avoiding the gap between the concrete and the second connecting member 22 during the second pouring of concrete into the reserved hole, and fundamentally avoiding the risk of water leakage.

[0050] S5. Pour the second time of concrete into the reserved hole to block the reserved hole, thereby completing the blocking of the reserved hole.

[0051] Preferably, the blocking method of the floor reserved hole blocking device of the present application further comprises the following steps:

[0052] S6. When pouring the second time of concrete into the reserved hole, a space for setting a waterproof layer 27 is reserved on the top of the second poured concrete, and after the second poured concrete solidifies, a layer of waterproof layer 27 is finally laid, and the top surface of the set waterproof layer 27 is flush with the upper surface of the floor slab, thereby enhancing the overall waterproof performance of the structure, and specifically, the waterproof layer 27 is preferably asphalt paste.

[0053] According to the blocking device and the blocking method, the structure surface obtained by construction does not have exposed bolts, thereby reducing the risk of water leakage, and the design of the second connecting member 22 cooperating with the first connecting member 21 avoids unnecessary cutting of the bolts, thereby improving the turnover of the device, reducing the cost, and increasing the benefit.

[0054] The application is described in detail above with reference to the drawings. Those skilled in the art can make various changes to the application according to the above description. Therefore, some details in the embodiments should not be regarded as limiting the application, and the scope of protection of the application is defined by the appended claims.
