Technical Field
[0001] The utility model belongs to the field of construction equipment, and in particular relates to a basement outer wall waterproof board structure which also serves as a template. Background Art
[0002] During the construction process, waterproofing of the basement is very important. During the construction of the basement exterior wall, in order to ensure the stability and waterproof performance of the structure, concrete is usually poured last in a certain part of the wall. This structure is called the basement exterior wall post-casting strip. The basement exterior wall post-casting strip often needs to wait until the basement exterior wall structure is completed before it can be closed, resulting in the failure to backfill the outer soil in time, increasing the safety risks of the foundation pit. In addition, the water and soil outside the basement can easily enter the basement before it is closed, affecting the dryness and cleanliness of the basement.
[0003] To solve the above problems, the conventional practice currently adopted is: first build a brick wall outside the basement; after the brick wall is built, plaster the outside; lay waterproof membrane and protective layer on the plaster layer; after the construction is completed, backfill the earth. However, the conventional practice has many problems such as long time consumption, inconvenient construction, unguaranteed strength, and poor waterproof effect. Therefore, it is urgent to develop a waterproof board for the exterior wall of the basement. Utility Model Content
[0004] The utility model aims to solve the deficiencies in the prior art and provide a basement exterior wall waterproof board structure which also serves as a template.
[0005] The specific technical solutions adopted by this utility model are as follows:

The waterproof board structure is arranged outside the post-cast strip of the basement outer wall to be cast, and comprises a water-swelling water stop strip, a prefabricated board, a water stop screw, a reinforcement piece, and a template; both sides of the post-cast strip are basement shear walls;
[0007] The prefabricated panels are arranged between the floor slab and the basement foundation from bottom to top; each prefabricated panel is composed of fixed steel bars and a concrete structure, wherein both ends of the fixed steel bars extend out of the concrete structure to be fixedly connected with the steel bars in the shear wall on both sides of the post-casting strip; two adjacent prefabricated panels are fixedly connected by filling mortar, and a water-expanding water stop strip is arranged between the two prefabricated panels to ensure a waterproof effect;
[0008] The precast panel is also embedded with a water-stop screw for fixing; the direction of the water-stop screw is perpendicular to the post-cast strip to be poured, and the length of the water-stop screw is greater than the thickness of the post-cast strip; the template is connected to the water-stop screw through a reinforcement piece, so that a cavity for pouring the post-cast strip is formed between the template and the precast panel.
[0009] Preferably, the fixed steel bars and the steel bars in the shear wall on both sides of the post-cast strip are connected by welding or binding.
[0010] Preferably, the reinforcement member is made of steel back ribs.

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below. The technical features in each embodiment of the utility model can be combined accordingly without conflicting with each other.
[0022] This embodiment, as a preferred mode of implementing the utility model, provides a basement exterior wall waterproof board structure which also serves as a template.
[0023] like Figure 1 As shown, the waterproof board structure is arranged on the outside of the post-cast strip 6 of the basement exterior wall that needs to be poured. Both sides of the post-cast strip 6 are the shear walls of the basement. Above the waterproof board structure is the floor slab 10 above the basement, and the bottom is the basement foundation 1. A brick formwork 2 is provided on the outside of the basement foundation 1. The brick formwork is a solid waterproof layer that can protect the basement structure from erosion by groundwater and soil moisture. In some cases, the brick formwork can also provide additional structural support to enhance the stability of the basement wall. It should be noted that the utility model does not limit the specific setting method of the basement foundation 1 and the brick formwork 2, and those skilled in the art can make a choice according to the specific working conditions.
[0024] The basement exterior wall waterproof board structure provided in this embodiment includes a water-swellable waterstop strip 3, a prefabricated board 4, a waterstop screw 5, a reinforcement member 7, and a template 8.
[0025] like Figure 2 As shown, the precast panels 4 provided in this embodiment are arranged between the floor 10 and the basement foundation 1, and a plurality of precast panels are arranged from bottom to top. Each precast panel 4 is composed of fixed steel bars 9 and a cast-in-place concrete structure, wherein both ends of the fixed steel bars 9 extend out of the concrete structure to be fixedly connected with the steel bars in the shear wall on both sides of the post-cast strip 6. Figure 3 It should be noted that the fixed steel bars 9 and the steel bars in the shear wall on both sides of the post-cast strip 6 can be connected by welding or binding.
[0026] In the structure of this embodiment, two adjacent prefabricated panels 4 are fixedly connected by filling mortar. It should be noted that two adjacent prefabricated panels 4 can also be connected by setting a tongue and groove to engage with each other. It is only necessary to inject waterproof coating at the engagement joint.
[0027] In the structure of this embodiment, a groove for fixing the water-swelling waterstop strip 3 is also provided between the two prefabricated panels 4. The water-swelling waterstop strip is a special waterproof material, which is mainly made of a variety of materials such as special rubber, inorganic water-absorbing material and high-viscosity resin. Its main feature is that it can expand rapidly after contacting water, and will produce 2 to 3 times of expansion deformation, fill all irregular surfaces, holes and gaps in the joints, and generate huge contact pressure, completely preventing water leakage. If the joints or construction joints are displaced, causing the gap to exceed the elastic range of the material, ordinary rubber waterstop materials may lose their water-stopping effect, but the water-swelling waterstop strip can still stop water by absorbing water and swelling, thereby maintaining the waterproof effect.
[0028] In the structure of this embodiment, a water-stop screw 5 for fixing is also embedded in the prefabricated plate 4. Figure 3 As shown, the direction of the water-stop screw 5 is perpendicular to the post-casting strip 6 to be cast, and the length of the water-stop screw 5 is greater than the thickness of the post-casting strip 6. The water-stop bolt can tightly fix the precast panel 4 on the outside of the post-casting strip 6 to prevent moisture from penetrating into the basement through joints or cracks, effectively protecting the structure from water damage. In this embodiment, a water-stop sheet is also provided at the joint between the precast panel 4 and the water-stop screw 5 therein to prevent moisture from penetrating through the joint.
[0029] like Figure 3 As shown, the angle between the two ends of the prefabricated board 4 and the shear wall provided in this embodiment is 45°, which is convenient for waterproofing the basement exterior wall. Waterproof coating can also be set at the angle between the two ends of the prefabricated board 4 and the shear wall. The utility model does not limit the specific material of the waterproof coating, and those skilled in the art can choose according to the working conditions.
[0030] Since the basement exterior wall post-casting strip needs to be cast later, the panel and wooden square are used as the template 8 in this embodiment. The template 8 is connected to the water stop screw 5 through the reinforcement 7, so that a cavity for casting the post-casting strip 6 is formed between the template 8 and the prefabricated panel 4.
[0031] In this embodiment, steel back ribs are used as reinforcement members 7. Steel back ribs are a commonly used reinforcement material in concrete structures. Their main function is to provide additional support and enhance the structural strength of concrete. During the concrete pouring process, steel back ribs can help disperse loads and pressure and prevent cracks and deformation. In addition, steel back ribs can also improve the bending, shear and tensile resistance of concrete.
[0032] The waterproof board structure provided by the utility model can be cast at the same time as the basement outer wall, so as to achieve the early closure of the outer wall, thereby speeding up the backfilling of the basement earthwork. In addition, the waterproof board structure has a wider applicability and is more convenient to construct. It not only enhances the integrity and waterproof performance of the structure, but also omits the plastering process, further improving the construction efficiency.
[0033] The above embodiment is only a preferred solution of the utility model, but it is not intended to limit the utility model. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, all technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
