Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a concrete waterstop steel plate assembly suitable for parts where the marking changes. Background Technology

[0002] In concrete construction, waterstop steel plates are a common waterproofing material widely used in the waterproofing treatment of building structures. However, existing waterstop steel plates often have certain shortcomings during concrete construction, especially when used with concrete of different grades. Particularly when multiple grades of concrete are poured together, the performance of the waterstop steel plate fails to effectively adapt to the bonding between different concrete grades and the control of cement slurry flow, leading to a significant decrease in waterproofing effect, as detailed below: 1. The Influence of Differences in Concrete Properties on Waterstop Steel Plates Different grades of concrete have different cement paste fluidity. High-grade concrete generally has lower fluidity, while low-grade concrete has higher fluidity. During construction, the cement paste in the concrete spreads with the concrete flow, especially the cement paste of low-grade concrete, which is more fluid and may spread to areas of high-grade concrete. This difference in cement paste fluidity can adversely affect the adhesion of the waterstop steel plate, leading to weak bonding between the waterstop steel plate and the concrete, reducing the waterproofing effect, and even potentially causing water leakage.

[0003] 2. Bonding issues of the waterstop steel plate Existing designs for waterstop steel plates have shortcomings in terms of adhesion to concrete. The surface of waterstop steel plates is typically smooth and flat, lacking an effective structural design to enhance bonding with concrete. When different grades of concrete are poured into the same structure, the difference in cement slurry flowability leads to unstable adhesion between the waterstop steel plate and the concrete, potentially causing weak bonding and affecting the overall waterproofing performance of the structure. Furthermore, insufficient adhesion between the waterstop steel plate and high-strength concrete can also lead to the loss of cement slurry from the high-strength concrete, reducing its strength and thus affecting the overall performance of the structure.

[0004] 3. Cement slurry flow control issues In existing technologies, methods for controlling cement grout flow are not entirely effective. The fluidity of cement grout is a critical factor, directly affecting the overall quality of the concrete and the waterproofing effect of the waterstop plate. If the cement grout flows excessively and spreads into high-strength concrete areas, it can lead to a decrease in the strength of the high-strength concrete and even damage its structural performance. Existing waterstop plates are not designed with sufficient consideration for controlling the fluidity of cement grout, resulting in the waterstop plates being unable to effectively prevent the impact of cement grout flow on high-strength concrete. Utility Model Content

[0005] To address the above problems, this utility model proposes a concrete waterstop steel plate assembly suitable for grade transition areas, in order to solve the problem that in the prior art, when waterstop steel plates are used at grade transition areas, the bonding between different grades of concrete is not strong, the flow of cement slurry cannot be controlled properly, and the performance of high-grade concrete is negatively affected.

[0006] This utility model is achieved through the following technical solution.

[0007] A concrete waterstop steel plate assembly suitable for grade conversion locations includes a waterstop steel plate, characterized in that it further includes: a normal thin plate perpendicularly disposed on the upper and lower sides of the waterstop steel plate along its length direction, wherein the normal thin plate is uniformly provided with a plurality of guide holes along its length direction, and a detachable mold cylinder is covered on the same side of the plurality of guide holes; a pre-anchor bar is horizontally fixedly disposed in the guide hole, one end of the pre-anchor bar extends through the guide hole to one side of the normal thin plate, and the other end of the pre-anchor bar movably extends through the bottom of the mold cylinder to the other side of the normal thin plate and is threadedly connected to a locking nut.

[0008] Preferably, the diameter of the guide hole is 3-6 cm, and the diameter of the pre-anchor bar is 0.2-0.4 times the diameter of the guide hole.

[0009] Preferably, the mold cylinder is a cylindrical structure with a depth of 8-10 cm and an inner diameter of 1.1-1.2 times the diameter of the guide hole.

[0010] Preferably, the guide hole is provided at intervals of 0.5-1 m along the normal length direction of the thin plate.

[0011] Preferably, a slurry overflow hole is provided at the top end of the mold cylinder away from the normal thin plate.

[0012] Preferably, the pre-anchor bar is fixed in the guide hole by 3-4 connecting rods in a spoke-like shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Based on the traditional waterstop steel plate, this utility model adds a normal thin plate. The normal thin plate interacts with the traditional waterstop steel plate, which helps to improve the adhesion between the waterstop steel plate and the concrete. The isolation provided by the normal thin plate prevents low-grade concrete from flowing and spreading into the high-grade concrete area, thus avoiding a decrease in the strength of the high-grade concrete. The guide holes on the normal thin plate can direct the highly fluid low-grade concrete to flow into the formwork. After the low-grade concrete has initially set and the formwork is removed, a concrete joint can be formed on the low-grade concrete side. The concrete joint can be embedded with the subsequently poured high-grade concrete, thus bonding the different grades of concrete into a unified structure. Furthermore, one end of the pre-anchored bar is embedded in the concrete joint, and the other end can be bonded to the subsequently poured high-grade concrete, further improving the bonding strength between the different grades of concrete.

[0014] Through the above innovative design, this utility model achieves effective improvements over traditional water-stop steel plates. It not only enhances the water-stopping effect but also effectively controls the flow of cement grout, avoiding any impact on the performance of concrete of different grades. The implementation of this technology can significantly improve the overall construction quality of concrete structures at grade transition points, ensuring higher durability and waterproofing performance during use.

All other embodiments obtained by those skilled in the art based on the embodiments provided by the present invention are within the scope of protection of the present invention. Example 1

A detachable mold cylinder 3 covers the plurality of guide holes 201 on the same side of the normal thin plate 2. A pre-anchor bar 4 is horizontally fixed in the guide hole 201. One end of the pre-anchor bar 4 passes through the guide hole 201 and extends to one side of the normal thin plate 2.

In the above structure, the water-stop steel plate 1 is a common water-stop steel plate structure in the prior art, with a width of 300 mm and a thickness of 3 mm. The water-stop steel plate 1 is made of cold-rolled steel plate, and the two sides are folded to form a groove structure to enhance the water-stopping effect. The folding height is 30-50 mm. The normal thin plate 2 can be welded to the water-stop steel plate 1, or the normal thin plate 2 can be integrally formed and connected with the water-stop steel plate 1 during processing. The pre-anchor bar 4 is a threaded steel bar, and one end of it is threaded for threaded connection with the locking nut 5. The mold cylinder 3 is an open cylindrical structure. The bottom of the mold cylinder 3 is provided with a through hole for the pre-anchor bar 4 to pass through. The mold cylinder 3 is made of thin steel plate, and its shape can be a cylindrical cylinder, a conical cylindrical cylinder, or a square cylinder. In the above structure, the normal thin plate 2 can increase the contact area between the water-stop steel plate 1 and the concrete, thereby improving the bonding force between the device and the concrete. Through the isolation of the normal thin plate 2, the low-grade concrete 6 can be prevented from flowing and spreading to the high-grade concrete area, so as to avoid the decrease in the strength of the high-grade concrete. The guide hole 201 can guide the highly fluid low-grade concrete 6 in a directional manner, so that the concrete flows into the mold cylinder 3. After the low-grade concrete 6 has initially set and the mold cylinder 3 is removed, a concrete joint 10 can be formed in the high-grade concrete area. The concrete joint 10 can be embedded with the subsequently poured high-grade concrete 7, so that the concrete of different grades can be bonded together into an integral structure. One end of the pre-anchor bar 4 has been pre-embedded in the concrete joint 10, and the other end can be bonded to the subsequently poured high-grade concrete 7, further improving the bonding strength between concrete of different grades.

[0019] Furthermore, in a preferred embodiment, the diameter of the guide hole 201 is 3-6 cm, and the diameter of the pre-anchor bar 4 is 0.3-0.5 times the diameter of the guide hole 201.

[0020] Furthermore, in a preferred embodiment, the mold cylinder 3 is a cylindrical structure with a depth of 8-10 cm and an inner diameter of 1.1-1.2 times the diameter of the guide hole 201.

[0021] Furthermore, in a preferred embodiment, the guide hole 201 is provided at intervals of 0.5-1 m along the length direction of the normal thin plate 2.

[0024] Furthermore, in a preferred embodiment, the pre-anchor bar 4 is fixed in the guide hole 201 by 3-4 connecting rods 401 in a spoke-like shape. Example 2

[0025] Based on the concrete waterstop steel plate assembly provided in Example 1, this example further explains its construction method or working principle, specifically: S1. Positioning and Installation Measure and mark the construction joint or expansion joint to ensure the accurate installation of the waterstop steel plate 1; tie and fix the waterstop steel plate 1 and the normal thin plate 2 to the steel reinforcement cage 5, so that the concave side of the waterstop steel plate 1 faces the water-facing side; S2, Low-grade concrete pouring Please see Figure 5 First, pour high-flowability low-grade concrete 6 on one side of the normal thin plate 2. The low-grade concrete 6 flows into the mold cylinder 3 through the guide hole 201. In order to ensure that the mold cylinder 3 is filled with low-grade concrete 6, the low-grade concrete 6 can be appropriately vibrated near the normal thin plate 2. When grout overflows from the grout overflow hole 301, it means that the mold cylinder 3 is filled with concrete grout. S3, Low-grade concrete curing The low-grade concrete 6 that has been poured is cured using conventional methods; S4. Mold Removal After the low-grade concrete 6 has solidified, loosen and remove the locking nut 5, and then remove the mold cylinder 3.

In order to facilitate the removal of the mold cylinder 3, a release agent can be applied to the inner wall of the mold cylinder 3 before the mold cylinder 3 is installed. S5, high-grade concrete pouring Low-flowability high-grade concrete 7 is poured on the other side of the normal thin plate 2. In order to improve the bonding effect between the high-grade concrete 7 and the pre-anchor bar 4 and concrete joint 10, the high-grade concrete 7 can also be appropriately vibrated near the normal thin plate 2. S6, high-grade concrete pouring The high-grade concrete that has been poured is cured using conventional methods.
