Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a hook net device used for waterproof construction of a structure root. Background Art

[0002] Cement-based penetrating crystalline waterproof coating is made of silicate cement and quartz sand as the main ingredients, mixed with a certain amount of active chemical substances. After mixing with water, it is formulated into a powder material that can be brushed or sprayed on the surface of cement concrete, and can also be directly used for dry-spreading construction on flat surfaces.

[0003] Under normal circumstances, cement-based penetrating crystallization waterproof materials are applied externally or manually dry-spread. If waterproofing construction is carried out according to conventional methods, it is not easy to dry-spread to the designated position in the inner corner area where the basement floor and the side wall are connected, and the concrete is easily vibrated and not dense, resulting in poor construction quality. The use of internal waterproofing layer will occupy a certain amount of usable space. The construction space outside the outer corner area where the basement floor and the side wall are connected is small, and the workers' construction techniques are different, which may easily lead to uneven brushing, bottom see-through and other phenomena, affecting the waterproofing quality. If dry laying is carried out directly, a large amount of materials will be used and the cost will be high.

[0004] The disclosed invention patent "A pre-laid anti-adhesive waterproof structure and construction method", application publication number CN114150712A mentioned that the cement-based penetrating crystalline waterproof material is dry-sprinkled on the pre-laid polymer waterproof membrane layer, and the poured concrete is vibrated and compacted through the concrete vibration process, so that the cement-based penetrating crystalline waterproof material is dispersed to the part of the poured concrete that is in contact with the cement-based penetrating crystalline waterproof material, forming an anti-seepage self-repairing waterproof layer.

[0005] However, the above construction method can only cover the bottom surface of the basement floor. The corners of the basement outer walls are important nodes for basement waterproofing, and are prone to leakage and difficult to repair completely. There is an urgent need to propose a low-cost and convenient construction solution. Summary of the Invention

[0006] The purpose of the utility model is to provide a hook net device for waterproofing construction at the root of the structure in response to the above-mentioned deficiencies of the existing technology. When the concrete falls, the cement-based hook net vibrates, so that the cement-based permeable crystallization material placed on the cement-based hook net is evenly dispersed and falls, forming an anti-seepage self-repairing concrete structure, solving the problem of waterproofing construction in the corner area of ​​the basement side wall and the bottom plate, and at the same time achieving the goal of reducing material consumption and reducing labor costs.

[0007] The purpose of this utility model is achieved by the following technical solutions:

[0008] A hook net device for waterproofing construction at the root of a structure, characterized in that it includes a cement-based hook net, the cement-based hook net has mesh holes, and arc-shaped hooks are respectively provided on the cement-based hook net. The arc-shaped hooks are used to connect with the transverse steel bars of the structure. An elastic sheet is connected to one side of the cement-based hook net, and the elastic sheet extends in a direction outside the cement-based hook net.

[0009] The cement-based hook net is in a bag-shaped structure, and the internal space of the bag-shaped structure is used to place the cement-based penetrating crystallization material used in the waterproof construction of the structure root.

[0010] Along the length extension direction of the cement-based hook net, two or more arc-shaped hooks are arranged on the cement-based hook net at even intervals.

[0011] The arc-shaped hook is formed by bending a plain round steel bar.

[0012] Along the length extension direction of the cement-based hook net, two or more elastic sheets are evenly arranged on the cement-based hook net.

[0013] The advantages of this utility model are: the use of cement-based customized screen allows the cement-based penetrating crystallization material to be constructed simultaneously and evenly dry-spread into the concrete at the corners of the basement; the cement-based hook net is easy to install and has high flexibility. The position and height can be adjusted to achieve the mixing of cement-based penetrating crystallization materials at different positions, reducing the quality problems caused by ordinary uneven dry spreading, loose vibration, etc., and at the same time can control the use of dry-spreading materials and reduce construction costs.

[0015] Figure 2 It is a side view of the utility model;

[0016] Figure 3 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0017] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

[0018] like Figure 1-3 As shown, the marks 1-8 in the figure respectively represent: foundation bottom plate 1, basement side wall 2, water-stop steel plate 3, transverse reinforcement 4, cement-based permeable crystallization material 5, elastic sheet 6, arc hook 7, and cement-based hook net 8.

[0019] Example: Figures 1 to 3As shown, the hook net device used for waterproofing construction at the root of the structure in this embodiment includes a cement-based hook net 8, an arc-shaped hook 7 and an elastic sheet 6.

[0020] The cement-based hook net 8 can be a bag-like structure such as a rectangular parallelepiped or cylindrical shape, so as to provide a space for placing the cement-based infiltrating crystallization material 5. The cement-based hook net 8 is provided with mesh holes, the mesh size of which matches the particle size of the cement-based infiltrating crystallization material 5. Generally speaking, when the cement-based infiltrating crystallization material 5 is piled on the cement-based hook net 8, most of the cement-based infiltrating crystallization material 5 will not fall out of the mesh holes due to the stacking in the height direction. However, when the cement-based hook net 8 vibrates, the cement-based infiltrating crystallization material 5 can fall out of the mesh holes of the cement-based hook net 8 in a dry manner.

[0021] The arc hook 7 is made of round steel bars and is fixed at a certain distance on the transverse steel bars at the root of the structure such as the exterior wall. After the fixation is completed, the bottom of the arc hook 7 should maintain a certain distance from the foundation base plate 1, which is conducive to the cement-based infiltration crystallization material 5 to be more evenly dispersed during the falling process.

[0022] In this embodiment, Figure 3 The figure shows the case where arc hooks 7 are set on both sides of the cement-based hook net 8. If the length of the cement-based hook net 8 is longer, more arc hooks 7 can be evenly spaced along the length extension direction of the cement-based hook net 8 to ensure that the cement-based hook net 8 can be stably fixed on the transverse steel bars.

[0023] The elastic sheet 6 is welded to the cement-based hook net 8 in a direction parallel to the foundation slab 1 and arranged along the longitudinal spacing of the cement-based hook net 8. When the concrete poured into the structure falls, it touches the elastic sheet 6, causing it to vibrate and transmit the vibration to the cement-based hook net 8, thereby causing the cement-based infiltrative crystallization material 5 placed on the cement-based hook net 8 to be evenly dispersed and fall, that is, the cement-based infiltrative crystallization material 5 is evenly mixed into the concrete, thereby improving the quality of the waterproof construction.

[0024] During construction, this embodiment Figure 3 Taking the situation shown as an example, the following steps are included:

[0025] 1) Bend the round steel bars into arc-shaped hooks 7. Two arc-shaped hooks 7 form a group, and are processed on the ground together with the cement-based hook net 8 and the elastic sheet 6 to form an integral combined structure.

[0026] 2) After the transverse reinforcement at the root of the structure is tied and before the concrete is poured, the cement-based hook net 8 is fixed to the transverse reinforcement 4 through the arc hook 7. The height and specific position of the cement-based hook net 8 are determined according to the area to be constructed, and the cement-based permeable crystallization material 5 is placed on the cement-based hook net 8.

[0027] In this embodiment, according to the actual situation of the construction area, a longer cement-based hook net that matches the length of the transverse steel bars 4 can be set, or several independent shorter cement-based hook nets can be fixed on the transverse steel bars 4 at a certain interval.

[0028] 3) When pouring concrete, the concrete touches the elastic sheet 6, thereby transmitting vibration and completing the uniform mixing of the cement-based infiltrative crystallization material 5.

[0029] After the structure is cast, the main body of the cement-based hooking net 8 remains inside the structure, which can also play a reinforcing role to further effectively enhance the structural performance.

[0030] In this embodiment, the dry spreading rate of the cement-based hook net 8 can be adjusted by adjusting the mesh size and body hardness of the screen. The combination of the elastic sheet 6 and the mesh size of the cement-based hook net 8 enables the dry spreading of the cement-based infiltrated crystallization material 5, allowing for light spreading without vibration and subsequent shedding.

[0031] This embodiment solves the problem of waterproof construction at the root position between the foundation slab 1 and the basement side wall 2. In order to further improve the water-stopping performance of the structural root and the upper structure, a water-stopping steel plate 3 is also provided between the two.

[0032] Although the above embodiments have described the concepts and embodiments of the present invention in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, so they are not described here one by one.
