[0030] Example 1

[0031] This embodiment provides an enhanced water stop structure to solve the problem of poor waterproof effect of the water stop steel strip provided at the post-cast strip in the related art.

[0032] like Figure 1 , Figure 2 As shown, an enhanced water stop structure is arranged on the structural layer 100 of the building, and includes a water stop 200 and a waterproof layer 300. The water stop 200 is arranged on the structural layer 100, and the water stop 200 includes a fixing portion 210 and a water stop portion 220, and the fixing portion 210 can limit and fix the water stop portion 220. The waterproof layer 300 is arranged on the structural layer 100, and the waterproof layer 300 covers the water stop 200, and a rounded corner is arranged at the connection between the waterproof layer 300 and the water stop 200.

[0033] Specifically, when the enhanced water stop structure is used for waterproofing, the enhanced water stop structure of this embodiment is set at the post-casting strip. The water stop 200 is set at the post-casting strip on the structural layer 100 of the building, and then the waterproof layer 300 is set on the structural layer 100. The waterproof layer 300 covers the water stop 200. Through the cooperation of the waterproof layer 300 and the water stop 200, the penetration and spread of water are blocked from the horizontal and vertical directions. The rounded corner is set at the connection between the waterproof layer 300 and the water stop 200, which can avoid stress concentration at the connection between the waterproof layer 300 and the water stop 200, thereby improving the connection strength between the waterproof layer 300 and the water stop 200. In addition, by selecting the material of the waterproof layer 300, the strength grade of the material used in the waterproof layer 300 is one level higher than that of the concrete poured previously. This not only increases the difficulty of moisture spreading and penetrating in the waterproof layer 300 and improves the waterproof effect of the waterproof layer 300, but also prevents the occurrence of construction cold joints between the post-cast strip and the concrete poured previously, further improves the connection strength of the present embodiment, and also improves the waterproof ability and waterproof effect of the present embodiment.

[0034] It should be noted that the structural layer 100 is the load-bearing part of the building, including components such as plates and beams. The structural layer 100 can bear the entire load of the entire building floor layer and plays a major role in the sound insulation and fire prevention of the building. The post-cast strip is a concrete strip left at the corresponding positions of the foundation slab, wall, and beam in accordance with the design or construction specifications in order to prevent harmful cracks that may be caused by the uneven shrinkage or settlement of the reinforced concrete structure during construction. In this embodiment, the water stop 200 and the waterproof layer 300 are arranged in the post-cast strip, which can effectively prevent the penetration and spread of moisture through the cooperation of the water stop 200 and the waterproof layer 300, thereby improving the aesthetics and service life of the building.

[0035] In one embodiment, for example, the fixing part 210 and the water stop part 220 are both set as metal parts, so that the service life of the fixing part 210 and the water stop part 220 is improved, and the water seepage prevention performance is further improved. It can be understood that the fixing part 210 and the water stop part 220 need to contact with water during work, so metals or alloys that do not react with water can be selected as materials, such as aluminum alloy, stainless steel, copper alloy, etc. In the actual construction process, the fixing part 210 and the water stop part 220 can also use different materials according to different situations. For example, the fixing part 210 needs to limit and fix the water stop part 220, and the strength requirement is high. Then, stainless steel, nickel-chromium alloy, etc., which do not react with water and have high strength, are selected to make it. The water stop part 220 is mainly used to block water, so stainless steel, aluminum alloy, etc., which are low-cost metals or alloys, can be selected to make it, so that the materials of the fixing part 210 and the water stop part 220 are suitable, and the cost of this embodiment is reduced without affecting normal operation.

[0036] In one embodiment, for example, Figure 1 , Figure 2 As shown, the waterproof layer 300 includes a first waterproof layer 310, a second waterproof layer 320 and a third waterproof layer 330. The first waterproof layer 310 covers the fixing portion 210, and the second waterproof layer 320 and the third waterproof layer 330 sequentially cover the first waterproof layer 310. The waterproof layer 300 is provided in multiple layers to improve the waterproof capability of the waterproof layer 300. Even if a single layer of the waterproof layer 300 is penetrated by water, the waterproof layer 300 can still maintain its waterproof capability. The multiple layers are provided to effectively prevent the large-scale penetration and spread of water.

[0037] In one embodiment, for example, Figure 1 , Figure 2 As shown, the water stop portion 220 is vertically arranged on the fixing portion 210, and the water stop portion 220 sequentially passes through the first waterproof layer 310 and the second waterproof layer 320, and extends into the third waterproof layer 330. The water stop portion 220 extends into the third waterproof layer 330, which can improve the ability of the water stop portion 220 to block water penetration in the lateral direction, thereby improving the waterproof ability and waterproof effect of this embodiment.

[0038] In one embodiment, for example, Figure 1 , Figure 2 As shown, a fillet is provided at the connection between the third waterproof layer 330 and the water stop portion 220. The fillet is provided at the connection between the third waterproof layer 330 and the water stop portion 220 to avoid stress concentration between the third waterproof layer 330 and the water stop portion 220, improve the overall connection strength between the fixing portion 210, the water stop portion 220 and the waterproof layer 300, and extend the service life of this embodiment.

[0039] In one embodiment, illustratively, the first waterproof layer 310 includes a first leveling layer, a first waterproof coating, an additional layer and a waterproof protective layer. The first leveling layer covers the structural layer 100 and the fixing portion 210 of the water stop 200. The first waterproof coating, the additional layer and the waterproof protective layer are sequentially arranged on the first leveling layer. First, the first leveling layer is arranged to facilitate the flat arrangement of other material layers in the first waterproof layer 310, thereby improving the reliability and aesthetics of this embodiment. Secondly, the first waterproof layer 310 is arranged on the first leveling layer to block moisture. Furthermore, the additional layer is a polyurethane waterproof coating and a flatly arranged glass fiber cloth. Since the glass fiber cloth has high strength and is brittle, the additional layer is arranged to cooperate with other waterproof layers 300 to improve the overall strength of this embodiment and prevent the occurrence of construction cold joints. Next, a waterproof protective layer is arranged on the additional layer to further prevent moisture penetration.

[0040] In one embodiment, for example, Figure 1 , Figure 2As shown, the second waterproof layer 320 includes a ceramsite concrete cushion layer, the thickness of the ceramsite concrete cushion layer is L1, and the height of the fixing part 210 is L2, which satisfies: L1 ≥ L2. The thickness of the second waterproof layer 320 is greater than the height of the fixing part 210, so that the fixing part 210 can cooperate with the second waterproof layer 320 to block moisture. At the same time, the second waterproof layer 320 can also completely cover the fixing part 210 to protect the fixing part 210 and improve the service life of this embodiment.

[0041] The second waterproof layer 320 is set as a ceramsite concrete cushion layer. Specifically, the ceramsite concrete cushion layer is made of cement, sand, and ceramsite in proportion. The specific proportion relationship can be determined according to the actual construction situation. For example, a more suitable ratio is 1:3:3 for cement, sand, and ceramsite. Since the sand ratio has a significant effect on the workability of the ceramsite concrete cushion layer, that is, it has a significant effect on the fluidity, cohesiveness, and water retention of the ceramsite concrete cushion layer.

[0042] First, in terms of fluidity, under the conditions of certain cement dosage and water-cement ratio, the mortar composed of sand and cement paste plays a lubricating and rolling role between coarse aggregates, which can reduce the friction between coarse aggregates. Therefore, within a certain range, as the sand ratio increases, the fluidity of concrete increases. On the other hand, since the specific surface area of ​​sand is larger than that of coarse aggregate, as the sand ratio increases, the total surface area of ​​coarse and fine aggregates increases. Under the condition of a certain amount of cement paste, the amount of paste wrapped on the aggregate surface decreases, the lubricating effect decreases, and the fluidity of concrete decreases. Therefore, when the sand ratio exceeds a certain range, the fluidity decreases as the sand ratio increases. By controlling the amount of sand, the fluidity of the ceramsite concrete cushion can be controlled.

[0043] Secondly, the effect on cohesion and water retention. When the sand ratio decreases, the cohesion and water retention of the concrete decrease, and it is easy to produce bleeding, segregation and slurry. When the sand ratio increases, the cohesion and water retention increase. In addition, when the sand ratio is too large, when the cement slurry is not enough to wrap the aggregate surface, the cohesion will also decrease. In summary, in actual production, different proportions of suitable ceramsite concrete cushion layers can be configured according to the site conditions.

[0044] In one embodiment, the third waterproof layer 330 includes a second leveling layer and a second waterproof coating, the second leveling layer is arranged on the second waterproof layer 320, and the second waterproof coating is arranged on the second leveling layer. The second leveling layer is arranged in the third waterproof layer 330, so that the ceramsite concrete cushion layer in the second waterproof layer 320 can be smoothed and leveled, and the second waterproof layer 320 with a difficult surface is prevented from affecting subsequent operations. Then, the second waterproof coating is arranged on the second leveling layer, which can further improve the waterproof effect and waterproof ability of this embodiment.

[0045] It should be noted that in this embodiment, the waterproof layer 300 is set to three layers, taking into account both the waterproof performance and the structural strength of the waterproof layer 300, so as to achieve the purpose of being waterproof, beautiful and durable. According to different actual conditions, any number of layers of waterproof layer 300 can be set, and the waterproof ability of the waterproof layer 300 can be improved by stacking the waterproof coating layer and the leveling layer within a reasonable range.

[0046] In one embodiment, for example, Figure 1 , Figure 2 As shown, the fixing part 210 is set as an L-shaped plate, and two fixing parts 210 are provided, and the two fixing parts 210 are respectively arranged on both sides of the water stop part 220, and abut against the water stop part 220. The water stop part 220 is fixed by the fixing part 210, so that the setting of the water stop part 220 is more flexible, and it can be fixed at any suitable position, playing the role of water stopping and anti-seepage.

[0047] In one embodiment, for example, Figure 1 , Figure 2 As shown, the water stop portion 220 is a straight plate, and the water stop portion 220 is arranged on the structural layer 100. The fixing portion 210 is provided with a fixing piece, and the fixing portion 210 can be relatively fixed to the structural layer 100 through the fixing piece. Specifically, a through hole is opened on the contact surface of the fixing portion 210 close to the structural layer 100, and the fixing piece is inserted into the through hole to relatively fix the fixing portion 210 and the structural layer 100. Exemplarily, the fixing piece is set as an expansion bolt to ensure that the fixing portion 210 can be reliably fixed to the structural layer 100.

[0048] In one embodiment, illustratively, the water stop 200 can also be set to other shapes as long as it can achieve a waterproof effect. For example, the water stop 200 can be set to an inverted T-shaped plate, which can effectively achieve a waterproof effect and improve the waterproof ability. It should be noted that during construction work, when laying the waterproof layer 300 for the first time, the water stop 200 of about 300 mm is pre-buried, and 10 cm to 15 cm of the water stop 200 is left outside the waterproof layer 300. After the first laying is completed, confirm that the waterproof layer 300 and the water stop 200 laid for the first time are in the correct position, and after the strength and properties are appropriate, the second laying is carried out to cover the water stop 200 completely, ensuring that the construction process is safe and reliable, and can also prevent the external pressure water from extending.

[0049] In one embodiment, for example, Figure 1As shown, a finishing layer 400 is also provided on the waterproof layer 300, and the finishing layer 400 includes an adhesive layer 410 and a stone finishing 420, and the adhesive layer 410 and the stone finishing 420 are sequentially covered on the waterproof layer 300. Adding the finishing layer 400 on the waterproof layer 300, that is, pasting the stone finishing 420 on the waterproof layer 300 through the adhesive layer 410, is equivalent to applying a layer of protection to the waterproof layer 300 through the stone finishing 420, improving the thermal insulation, fire resistance, waterproofness and other effects of the waterproof layer 300, and at the same time, it can also make this embodiment more beautiful after construction.

[0050] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
