Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a construction method of a cement-based permeable crystallization material used at the root position of a structure. 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 parts.

[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 internal laying of the waterproof layer will occupy a certain amount of usable space. The outer construction space of the outer corner area where the basement floor and the side wall are connected is small, and the workers have different construction techniques, which is prone to uneven brushing and bottom penetration, 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 reverse-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 easy-to-construct solution. Summary of the invention

[0006] The purpose of the present invention is to provide a construction method for cement-based penetrating crystallization materials at the root position of the structure based on the above-mentioned deficiencies of the prior art. When the concrete falls, the cement-based hook net is vibrated, so that the cement-based penetrating crystallization material placed on the cement-based hook net is evenly dispersed and falls, forming an impermeable self-repairing concrete structure, solving the problem of waterproof 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 the present invention is achieved by the following technical solutions: A construction method of cement-based permeable crystallization material for the root of a structure, characterized in that the construction method comprises the following steps: A cement-based hook net is installed on the transverse steel bars at the root of the structure through an arc-shaped hook, wherein the cement-based hook net has mesh holes, and an elastic sheet is arranged on one side of the cement-based hook net; Before pouring concrete, a cement-based permeable crystallization material is placed on the cement-based hook net; Concrete is poured, and the concrete contacts the elastic sheet to cause the elastic sheet to vibrate. The elastic sheet transmits the vibration to the cement-based hook net, and the cement-based infiltrative crystallization material is evenly dispersed and falls from the mesh holes of the cement-based hook net, thereby evenly mixing the cement-based infiltrative crystallization material into the concrete.

[0008] The dry spreading rate of the cement-based infiltration crystallization material is controlled by adjusting the mesh size and body hardness of the cement-based hook net.

[0009] By combining the mesh size of the elastic sheet and the cement-based hook net, the cement-based infiltration crystallization material is evenly dispersed and dropped only after vibration.

[0010] According to the pouring range of the concrete, one or more cement-based hook nets are arranged on the transverse steel bars.

[0011] After the concrete pouring is completed, the cement-based hook net is buried inside the structure as a reinforcement.

[0012] The advantages of the present invention are: the cement-based customized screen is used to enable the cement-based penetrating crystallization material to be constructed simultaneously and evenly dry-spread into the concrete at the corner of the basement; the cement-based hook net is easy to install and has high flexibility, and the cement-based penetrating crystallization material at different positions can be blended by adjusting the position and height, thereby reducing the quality problems originally caused by ordinary uneven dry spreading, loose vibration, etc., and at the same time, the amount of dry-spreading material used can be controlled to reduce construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is the installation schematic diagram of the present invention; Figure 2 is a side view of the present invention; Figure 3 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0014] The features of the present invention and other related features are further described in detail below through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art: like Figure 1-3 As shown, the marks 1-8 in the figure respectively represent: foundation slab 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, cement-based hook net 8.

[0015] Example: Figures 1 to 3 As 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 hook 7 and an elastic sheet 6.

[0016] The cement-based hook net 8 can be a bag-shaped structure such as a cuboid or a cylinder, so that it has a space for placing the cement-based infiltration crystallization material 5. The cement-based hook net 8 is provided with mesh holes, the mesh number of which matches the particle size of the cement-based infiltration crystallization material 5. Generally speaking, when the cement-based infiltration crystallization material 5 is piled on the cement-based hook net 8, most of the cement-based infiltration crystallization material 5 will not fall from the mesh holes by themselves because of the stacking in the height direction. However, when the cement-based hook net 8 vibrates, the cement-based infiltration crystallization material 5 can fall from the mesh holes of the cement-based hook net 8 in a dry scattering manner.

[0017] The arc hook 7 is formed by bending a plain round steel bar and is fixed at a certain interval on the transverse steel bars at the root of the structure such as the exterior wall. After being fixed, the bottom of the arc hook 7 should maintain a certain distance from the foundation slab 1, which is conducive to more uniform dispersion of the cement-based infiltration crystallization material 5 during the falling process.

[0018] In this embodiment, Figure 3 What is shown is the situation 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.

[0019] 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 by 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 penetrating crystallization material 5 placed on the cement-based hook net 8 to be evenly dispersed and fall, that is, the cement-based penetrating crystallization material 5 is evenly mixed into the concrete, thereby improving the quality of the waterproof construction.

[0020] During construction, this embodiment Figure 3 Taking the situation shown as an example, the following steps are included: 1) The round steel bar is bent into an arc-shaped hook 7, two arc-shaped hooks 7 form a group, and the cement-based hook net 8 and the elastic sheet 6 are processed on the ground to form an integral combined structure.

[0021] 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.

[0022] In this embodiment, according to the actual situation of the construction area, a longer cement-based hook net matching the length of the transverse reinforcement 4 can be provided, or a number of independent shorter cement-based hook nets can be fixed on the transverse reinforcement 4 at a certain interval.

[0023] 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.

[0024] 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.

[0025] In the specific implementation of this embodiment: the dry spreading rate of the cement-based hook net 8 can be adjusted by the mesh size of the screen and the hardness of the body. The elastic sheet 6 and the mesh size of the cement-based hook net 8 can realize the function of dry spreading of the cement-based infiltrative crystallization material 5 with slight paving but falling after vibration.

[0026] 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.

[0027] Although the above embodiments have described in detail the concepts and embodiments of the present invention with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and changes can still be made to the present invention without departing from the scope of the claims, so they are not described one by one here.
