Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an anti-seepage structure for anti-floating anchor rods of a basement floor slab. Background Technique

[0002] When constructing underground building structures such as basements in geological areas with a high groundwater level, it is usually necessary to first construct an anti-floating anchor rod structure to limit the buoyancy of subsequent groundwater from lifting the basement as a whole, resulting in damage to the building structure.

[0003] After retrieval, Chinese Patent Publication No. CN219261136U discloses a waterproof structure at the anti-floating anchor rod node, which includes a steel bar main body constituting the anti-floating anchor rod and a grouting pipe for supporting and fitting the steel bar main body. An installation fastener is also provided on the grouting pipe. The installation fastener includes three positioning blocks evenly connected to the outer wall of the grouting pipe, and a clamping groove for fitting and installing the steel bar main body is provided between adjacent positioning blocks. An expansion plug is provided on the inner wall of the clamping groove. A waterproof cover is also sleeved on the top ends of the steel bar main body and the grouting pipe. A cavity is provided at the bottom of the waterproof cover. In this application, the provided grouting pipe and the three positioning blocks connected to the grouting pipe can leave a clamping groove for installing the steel bar main body, and through the expansion plug provided on the inner wall of the clamping groove, the gap between the steel bar main body and the grouting pipe can be effectively filled, thus effectively avoiding the phenomenon of groundwater seeping upward.

[0004] However, in the above technical solution, only by setting the grouting pipe and the three positioning blocks connected to the grouting pipe, a clamping groove for installing the steel bar main body can be left, and through the expansion plug provided on the inner wall of the clamping groove, the gap between the steel bar main body and the grouting pipe is filled. However, a relatively thick water stop ring is installed in the waterproof cover to prevent groundwater seepage. When the thickness of the water stop ring is relatively thick, its expansion speed will slow down, and the expansion speed of the water stop ring will further slow down at low temperatures. In the case of the superposition of the two, it is easy to occur that the expansion speed is slow, resulting in water seepage. Summary of the Utility Model

[0005] The purpose of the utility model is to propose an anti-seepage structure for anti-floating anchor rods of a basement floor slab aiming at the problems existing in the background technique.

[0006] The technical solution of the utility model: an anti-seepage structure for anti-floating anchor rods of a basement floor slab, including a base layer, which is connected with a waterproof layer, and the waterproof layer is connected with a basement floor slab layer; an anti-floating anchor rod main body, which is connected to the base layer, and the anti-floating anchor rod main body is sequentially arranged on the waterproof layer and the basement floor slab layer from bottom to top; a waterproof component, which is connected to the anti-floating anchor rod main body; in the use state of the waterproof component, the waterproof component fits with the anti-floating anchor rod main body to reduce the gap.

[0007] Preferably, the waterproof component includes a waterproof sleeve sleeved outside the anti-floating anchor rod main body, with a receiving cavity formed on the waterproof sleeve; an expansion water stop belt sleeved outside the anti-floating anchor rod main body, with a through hole formed on the expansion water stop belt and fitting the anti-floating anchor rod main body; and elastic members, with a plurality of elastic members evenly distributed at equal intervals and connected to the waterproof sleeve.

[0008] Preferably, a plurality of circumferentially distributed limiting protrusions are detachably connected to the inner wall of the waterproof sleeve.

[0009] Preferably, dovetail grooves are formed on the limiting protrusions and slidably connected to dovetail blocks connected to the inner wall of the waterproof sleeve.

[0010] Preferably, the elastic members are spring pieces, and the spring pieces are connected to the inner wall of the waterproof sleeve and the limiting protrusions.

[0011] Preferably, water stop rings are connected to both the upper and lower ends of the expansion water stop belt.

[0012] Preferably, multiple layers of expansion waterproof rings are sleeved on the outer wall of the waterproof sleeve.

[0013] Compared with the prior art, the above technical solution of the present utility model has the following beneficial technical effects:

[0014] In the present utility model, the waterproof component absorbs water and expands. The waterproof components in the waterproof component are stacked in multiple layers up and down to form multiple waterproof layers. Some of the waterproof components have a fast expansion speed and some have a slow expansion speed. By combining the two, water penetration is prevented. After the waterproof components expand, the gap between them and the anti-floating anchor rod main body decreases, preventing water from penetrating through the gap between the two. Waterproof components are also provided on the outside of the waterproof component, which can prevent water penetration in all directions and further improve the waterproof ability.

[0021] As Figures 1-4 shown, a basement floor anti-floating anchor rod anti-seepage structure proposed by the present utility model includes a base layer 1, a waterproof layer 2, a basement floor layer 3, an anti-floating anchor rod main body 4, and a waterproof component. The upper end surface of the base layer 1 is connected to the waterproof layer 2, the waterproof layer 2 is connected to the basement floor layer 3, the anti-floating anchor rod main body 4 is connected to the base layer 1, and the anti-floating anchor rod main body 4 is arranged on the waterproof layer 2 and the basement floor layer 3 from bottom to top in sequence; a plurality of uniformly distributed fixing plates are connected to the anti-floating anchor rod main body 4, and the fixing plates position the steel bars forming the anti-floating anchor rod main body 4; the waterproof component is connected to the anti-floating anchor rod main body 4; in the use state of the waterproof component, the waterproof component absorbs water and expands, and the gap between the waterproof component and the anti-floating anchor rod main body 4 decreases after expansion, preventing water from penetrating through the gap between the two.

[0022] Embodiment 2

[0023] As Figures 2-4 shown, a basement floor anti-floating anchor rod anti-seepage structure proposed by the present utility model, compared with Embodiment 1, the detailed structure of the waterproof component is described in this embodiment. The waterproof component includes a waterproof sleeve 5, an expansion water stop belt 6, and an elastic member 7. The waterproof sleeve 5 is sleeved outside the anti-floating anchor rod main body 4, and a cylindrical accommodation cavity is provided on the upper end surface of the waterproof sleeve 5;

[0024] In an optional embodiment, a plurality of circumferentially distributed limiting protrusions 8 are detachably connected to the inner wall of the waterproof sleeve 5; the limiting protrusions 8 reduce the thickness of the expansion water stop belt 6 located outside the anti-floating anchor rod main body 4 by the protrusion of their volume, avoiding the excessive thickness of the expansion water stop belt 6 affecting the expansion speed;

[0025] In an optional embodiment, a dovetail groove 9 is provided on each of the limiting protrusions 8, and the dovetail groove 9 is slidably connected to a dovetail block 10 connected to the inner wall of the waterproof sleeve 5; the connection between the dovetail groove 9 and the dovetail block 10 facilitates the disassembly and installation of the limiting protrusions 8, thereby facilitating the installation of the water stop ring 11;

[0026] The expansion water stop belt 6 is sleeved outside the anti-floating anchor rod main body 4, a through hole fitting the anti-floating anchor rod main body 4 is provided on the expansion water stop belt 6, a plurality of elastic members 7 are evenly distributed at equal intervals, and the elastic members 7 are connected to the waterproof sleeve 5;

[0027] In an optional embodiment, the elastic member 7 is a spring piece, and the spring piece is connected to the inner wall of the waterproof sleeve 5 and the limiting protrusions 8; the spring piece is located in the middle of the expansion water stop belt 6, and the expansion water stop belt 6 is pushed to fit with the anti-floating anchor rod main body 4 by its own elastic force. After the expansion water stop belt 6 absorbs water, its volume will expand, and the upper and lower ends of the expansion water stop belt 6 expand to block the elastic member 7 to prevent water from penetrating;

[0028] In an alternative embodiment, water stop rings 11 are connected to both the upper and lower ends of the expansion water stop belt 6; when the water stop rings 11 are connected to the upper and lower ends of the expansion water stop belt 6, the three of them form multiple waterproof layers. The expansion water stop belt 6 is relatively thin and fits against the outer wall of the anti-floating anchor rod body 4, which can prevent water seepage caused by the slow expansion speed of the water stop rings 11.

[0029] In an alternative embodiment, multiple expansion waterproof rings 12 are sleeved on the outer wall of the waterproof sleeve 5; the expansion waterproof rings 12 are in contact with the waterproof layer 2, which can prevent water from penetrating from the outside of the waterproof sleeve 5 towards the basement floor layer 3.

[0030] In summary, when the present utility model is in use, the staff installs the anti-floating anchor rod body 4 into the pre-drilled hole, injects concrete mortar through the grouting pipe on the anti-floating anchor rod body 4. When groundwater seeps upward, water enters the cavity inside the waterproof sleeve 5 from the bottom of the waterproof sleeve 5. When the water enters, the water stop rings 11 absorb the water and expand. However, due to their large volume, their expansion speed is slow. Therefore, part of the water enters between the two water stop rings 11 and contacts the expansion water stop belt 6. The thickness of the expansion water stop belt 6 is thinner than that of the water stop rings 11. Therefore, when absorbing water, the water diffuses faster and the expansion speed is faster. After the expansion water stop belt 6 absorbs water, it expands and expands outwards to contact the inner wall of the waterproof sleeve 5 and the limiting convex block 8, and at the same time squeezes the elastic member 7. After the expansion water stop belt 6 and the water stop rings 11 expand, they fit against the inner wall of the waterproof sleeve 5 to prevent water from seeping in. The expansion waterproof rings 12 on the outer wall of the waterproof sleeve 5 expand after contacting water and fit tightly against the waterproof layer 2 to prevent water from penetrating.

[0031] The above has described in detail the embodiments of the present utility model with reference to the accompanying drawings. However, the present utility model is not limited thereto. Within the scope of knowledge possessed by those skilled in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
