Description

Technical Field

[0001] This utility model belongs to the technical field of raft foundation waterstop structure, and relates to a waterstop structure at the joint between tower crane foundation and raft foundation. Background Technology

[0002] During the construction of various treatment tanks in a wastewater treatment plant, a tower crane is usually installed in the middle of the tank. Before installing the tower crane, the tower crane foundation needs to be poured. The tower crane foundation is located inside the raft slab. Later, the raft slab and the tower crane foundation are poured into an integrated structure. However, during the later pouring of the raft slab, water seepage problems can easily occur at the contact surface between the raft slab and the tower crane foundation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a water-stopping structure at the joint between the tower crane foundation and the raft slab, which can effectively prevent water seepage.

[0004] The technical solution adopted by this utility model is as follows: a water-stopping structure at the joint between a tower crane foundation and a raft slab, including a water-stopping steel strip and a water-stopping strip. Half of the water-stopping steel strip is pre-embedded around the top of the tower crane foundation, and the other half is located in the raft slab to be poured. The water-stopping strip is arranged around the tower crane foundation and near the middle, and is placed at the joint surface where the raft slab to be poured and the tower crane foundation are poured together.

[0005] Furthermore, the aforementioned water-stop steel strip adopts a four-strip structure, which is bent upwards into a groove-shaped structure.

[0006] Furthermore, the bottom of the aforementioned water-stop steel strip is provided with auxiliary supporting steel bars.

[0007] Furthermore, a support plate is installed under the aforementioned waterstop strip. The support plate has a double vertical bending structure. The support plate consists of multiple pieces arranged around the side of the tower crane foundation near the center. Each support plate includes a first vertical section plate, a horizontal section plate, and a second vertical section plate. The upper end of the first vertical section plate is fixedly connected to one end of the horizontal section plate, and the other end of the horizontal section plate is vertically fixedly connected to the lower end of the second vertical section plate. The first vertical section plate is fixedly connected to the side of the tower crane foundation to form a clamping groove, which clamps the waterstop strip tightly against the side of the tower crane foundation.

[0008] Furthermore, a 3M adhesive layer is applied to the side of the aforementioned waterstop strip that is closely attached to the tower crane foundation.

[0009] Furthermore, a steel wire is installed between the clamping grooves between the two adjacent support plates.

[0010] Furthermore, the aforementioned first vertical section plate is bonded to the tower crane foundation using 3M adhesive.

[0011] Furthermore, the height of the second vertical section plate is lower than the top surface of the waterstop strip.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] (1) This utility model adopts a double water-stopping structure of water-stopping steel strip and water-stopping strip, which can effectively prevent water seepage around the original tower crane foundation after the raft slab and tower crane foundation are poured together, improve the waterproofing effect, and effectively solve the problem of water seepage at the contact surface between the raft slab and the tower crane foundation during the pouring process.

[0014] (2) The groove structure provides better connection reliability, and the wider water-stop steel strip provides better water-proofing effect;

[0015] (3) Through the auxiliary support steel bars, the waterstop steel strip that is half suspended can be complexly supported, so as to avoid the waterstop steel strip from bending and being damaged.

[0016] (4) A support plate is set around the tower crane foundation. The waterstop strip can be positioned by the clamping groove on the support plate to prevent it from falling off, improve the reliability and accuracy of the positioning, and avoid affecting the later raft foundation construction. The support plate has a simple structure, is easy to manufacture, and has a low cost.

[0017] (5) The 3M adhesive layer is bonded to the side of the tower crane foundation. With the auxiliary support of the support plate, the waterstop strip can be accurately positioned.

[0018] (6) The straightened steel wire can play an auxiliary supporting role for the waterstop strip, so that the bonding joint of the waterstop strip is less stressed, the bonding and positioning effect is improved, and the positioning is more reliable.

[0019] (7) The support plate can be reliably and stably connected to the tower crane foundation vertically near the middle position by using 3M adhesive. Attached Figure Description

[0022] Figure 3 This is a top view of the water-stop structure at the junction of the tower crane foundation and the raft. Detailed Implementation

[0023] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: As Figures 1-3As shown, a water-stopping structure at the joint between a tower crane foundation and a raft foundation includes a water-stopping steel strip 1 and a water-stopping strip 3. Half of the water-stopping steel strip 1 is embedded around the top of the tower crane foundation 2, and the other half is located on the raft foundation 4 to be poured. The water-stopping strip 3 is arranged around the tower crane foundation 2 and near the middle, placed at the joint surface where the raft foundation 4 and the tower crane foundation 2 are poured together. The double water-stopping structure of the water-stopping steel strip and the water-stopping strip can effectively prevent water seepage around the original tower crane foundation after the raft foundation and the tower crane foundation are poured together, thus improving the waterproofing effect.

[0025] To improve connection reliability and water-proofing effect, the water-stop steel strip 1 adopts a four-strip structure, which is bent upward into a groove structure. The four strip structures are set with a 45-degree inclination at the corners and are welded after being joined together. The groove structure has better connection reliability, and the water-stop steel strip is wider, resulting in better water-proofing effect.

[0026] Because the waterstop steel strip is a thin sheet structure with low rigidity, it is prone to bending. To address this, auxiliary support steel bars 5 are provided at the bottom of the waterstop steel strip 1, with at least one bar on each side. Through the auxiliary support steel bars, the waterstop steel strip that is half suspended can be provided with complex support, preventing the waterstop steel strip from bending and being damaged.

[0027] To facilitate the positioning of the waterstop strip during installation, a support plate 6 is installed below the waterstop strip 3. The support plate 6 has a double vertical bending structure. The support plate 1 consists of multiple plates arranged around the side of the tower crane foundation 2 near the center. Each support plate 6 includes a first vertical section plate 601, a horizontal section plate 602, and a second vertical section plate 603. The upper end of the first vertical section plate 601 is fixedly connected to one end of the horizontal section plate 602, and the other end of the horizontal section plate 602 is vertically fixedly connected to the lower end of the second vertical section plate 603. The first vertical section plate 601 is fixedly connected to the side of the tower crane foundation 2, forming a clamping groove 604. The clamping groove 604 clamps the waterstop strip 3 tightly against the side of the tower crane foundation. By setting support plates around the tower crane foundation, the waterstop strip can be auxiliaryly supported and positioned by the clamping grooves on the support plates, preventing it from falling off, improving the reliability and accuracy of positioning, and avoiding affecting the subsequent raft foundation construction. The support plate structure is simple, easy to manufacture, and low in cost.

[0028] To ensure more precise positioning, a 3M adhesive layer 7 is installed on one side of the waterstop strip 3, which is closely attached to the tower crane foundation 2. The 3M adhesive layer is used to bond the waterstop strip to the side of the tower crane foundation. With the auxiliary support of the support plate, the waterstop strip can be precisely positioned.

[0029] To further improve positioning accuracy and prevent the waterstop strip from bending between adjacent support plates due to weak adhesion and the elastic effect of the strip, a steel wire 605 is installed between the clamping grooves 604 of the two adjacent support plates 6. The straightened steel wire can provide auxiliary support for the waterstop strip, reducing the stress on the adhesive joint of the waterstop strip, improving the adhesive positioning effect, and making the positioning more reliable.

[0030] For ease of installation, the first vertical section plate 601 is bonded to the tower crane foundation 2 with 3M adhesive. The 3M adhesive can reliably and stably connect the support plate to the vertical position near the middle of the tower crane foundation.

[0031] In order to avoid affecting the water-stopping effect of the waterstop strip, the height of the second vertical section plate 603 is lower than the top surface of the waterstop strip 3, so that the waterstop strip 3 can have sufficient face to the already poured tower crane foundation.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
