The casting trough is exposed for a long time before and after the casting of the post-cast strip. After the debris accumulates in the post-cast trough, it is not only inconvenient to clean, but also sewage can easily enter the gap between the first-cast concrete and the bottom layer, thereby increasing the difficulty of the later construction of the basement structure.
[0029] In order to solve this technical problem, the utility model provides a basement floor post-casting belt sinking device.
[0030] Specifically, please refer to Figure 1 and Figure 3 The basement floor post-casting belt sinking device specifically includes:
[0031] A support platform 1 is provided with a groove 101 on the top of the support platform 1, a post-cast strip body 104 is provided in the groove 101, and both sides of the post-cast strip body 104 are provided with a pre-cast concrete layer 103 located above the support platform 1, the top of the post-cast strip body 104 is flush with the top of the pre-cast concrete layer 103, and the bottom of the post-cast strip body 104 is lower than the bottom of the pre-cast concrete layer 103.
[0032] The utility model provides a basement floor post-cast strip sinking device, through the support platform 1 and the groove 101, the setting of the groove 101 allows the depth of the post-cast strip body 104 after pouring to be greater than the pre-cast concrete layer 103, when debris or sewage falls in, the debris and sewage enter the groove 101 and are easier to clean, and the sewage stored in the groove 101 can reduce the infiltration into the gap at the bottom of the pre-cast concrete layer 103, thereby reducing the difficulty of later construction.
[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0036] Example 1, please refer to Figure 1 and Figure 3 , a basement floor post-casting strip sinking device, comprising a support platform 1, a groove 101 is arranged on the top of the support platform 1, a post-casting strip body 104 is arranged in the groove 101, and both sides of the post-casting strip body 104 are provided with a pre-cast concrete layer 103 located above the support platform 1, the top of the post-casting strip body 104 is flush with the top of the pre-casting concrete layer 103, and the bottom of the post-casting strip body 104 is lower than the bottom of the pre-casting concrete layer 103, by increasing the depth of the post-casting strip body 104, the connection between the pre-casting concrete layer 103 of the basement and the post-casting strip body 104 can be strengthened, and the stability of the overall structure can be improved; increasing the depth of the post-casting strip body 104 can better adapt to the settlement of the foundation and reduce the settlement difference, and deepening the post-casting strip body 104 can increase the contact area between it and the pre-casting concrete layer 103, and improve the waterproof effect;
[0037] The setting of the groove 101 allows the depth of the post-cast strip body 104 to be greater than the pre-cast concrete layer 103 after pouring. When debris or sewage falls in, the debris and sewage enter the groove 101 and are easier to clean. The sewage stored in the groove 101 can reduce the infiltration into the gap at the bottom of the pre-cast concrete layer 103, thereby reducing the difficulty of later construction. A high-pressure water gun can be used to flush and clean the sewage and debris in the groove 101.
[0038] Further, such as Figure 1As shown, a steel protection layer 102 is arranged between the top of the support platform 1 and the first poured concrete layer 103. The main function of the steel protection layer 102 is to protect the structure of the concrete, reduce the erosion by oxygen and moisture, and effectively isolate harmful substances in the external environment, thereby extending the service life of the concrete.
[0039] Further, such as Figure 1 As shown, a waterproof component is provided at the bottom of the support platform 1 , and the waterproof component is used for waterproofing the support platform 1 , that is, the waterproof component can reduce the penetration of moisture in the foundation into the support platform 1 .
[0040] Further, such as Figure 1 As shown, the waterproof component includes a first waterproof layer 2, which is arranged at the bottom of the support platform 1. The first waterproof layer 2 can be made of TPO waterproof membrane, which is made of thermoplastic polyolefin TPO synthetic resin as the base material and has excellent aging resistance and waterproof effect.
[0041] Further, such as Figure 1 As shown, the waterproof component also includes a second waterproof layer 3, which is arranged at the bottom of the first waterproof layer 2. The second waterproof layer 3 can adopt SBS modified asphalt waterproof membrane, which has excellent high temperature resistance and can be used in the temperature range of -25°C to +100°C. It has high elasticity and fatigue resistance, as well as strong puncture resistance and tear resistance.
[0042] Example 2 further optimizes the basement floor post-casting belt sinking device provided in Example 1. Specifically, Figure 1-Figure 2 As shown, a water stop is provided between the post-cast strip body 104 and each pre-cast concrete layer 103 , and the water stop is used to stop water seeping into the connection between the post-cast strip body 104 and the pre-cast concrete layer 103 .
[0043] Further, such as Figure 2 As shown, the waterstop member is a waterstop plate 106, which is connected between the post-cast strip body 104 and the pre-cast concrete layer 103. The working principle of the waterstop plate 106 is to avoid water seepage problems at the junction of new and old concrete due to loose concrete pouring. It achieves the effect of water stopping and waterproofing by changing the water penetration path and extending the water penetration route.
[0044] Example 3 further optimizes the basement floor post-casting belt sinking device provided in Example 2. Specifically, Figure 1-Figure 3As shown, a blocking member is provided between the post-cast strip body 104 and each pre-cast concrete layer 103, and the blocking member is used to block the concrete when pouring the pre-cast concrete layer 103; the blocking member is a dense mesh 105, and the dense mesh 105 is located between the pre-cast concrete layer 103 and the post-cast strip body 104, and the dense mesh 105 is fixedly connected to the water stop plate 106. The setting of the dense mesh 105 can provide a uniform construction base surface for the pre-cast concrete layer 103, facilitate subsequent construction process operations, and help reduce the shrinkage and deformation of the concrete poured in the pre-cast concrete layer 103, thereby improving the accuracy and effect of construction.
[0045] Example 4 further optimizes the basement floor post-casting belt sinking device provided in Example 2. Specifically, Figure 4-Figure 5 As shown, a blocking member is arranged between the post-cast strip body 104 and each pre-cast concrete layer 103, and the blocking member is used to block the concrete when pouring the pre-cast concrete layer 103; the blocking member is a baffle 4, and the baffle 4 is located between the pre-cast concrete layer 103 and the post-cast strip body 104, and the baffle 4 is fixedly connected to the water stop plate 106. The setting of the baffle 4 makes the connection between the baffle 4 and the pre-cast concrete layer 103 and the post-cast strip body 104 present a concave and convex state, which can not only improve the connection strength, but also further improve the waterproof effect of the connection.
