Description

TECHNICAL FIELD

[0001] The present application relates to the field of honeycomb cores, in particular to a honeycomb core with self-waterproof function and a waterproof construction method thereof. BACKGROUND

[0002] The honeycomb core is a whole cavity mold member with reinforcing ribs, which is made of super-high-strength inorganic cementing material as the main raw material and fiber reinforcement. The honeycomb core has reinforcing ribs to enhance impact performance and strength, and the bottom plate has reinforcing ribs and is clamped with steel bars or steel wire mesh. At present, the honeycomb core is commonly used for constructing cast-in-place concrete hollow floor, compared with the traditional thin-walled pipe hollow floor, the hollow rate can be increased by about 15%, which greatly reduces the self-weight of the floor structure, thereby the amount of concrete and steel bars and other materials can be greatly reduced, and the heat preservation and sound absorption performance is significantly improved.

[0003] The honeycomb core products on the market have no waterproof function, and the waterproof of the concrete hollow floor is only dependent on the structure waterproof of the cast-in-place concrete part. If the construction is not in place, it often causes water leakage at the bottom of the plate, resulting in poor waterproof effect of the honeycomb core hollow floor. SUMMARY

[0004] In order to improve the waterproof effect of the honeycomb core hollow floor, the present application provides a honeycomb core with self-waterproof function and a waterproof construction method thereof.

[0005] In the first aspect, the present application provides a honeycomb core with self-waterproof function, which adopts the following technical scheme:

[0006] The honeycomb core with self-waterproof function comprises a honeycomb core body and a waterproof coating formed inside the honeycomb core body, and a through hole is formed on the honeycomb core body for the waterproof coating to enter.

[0007] By adopting the above technical scheme, the waterproof coating enters the inside of the honeycomb core body through the reserved through hole, and forms a waterproof coating on the inner wall of the honeycomb core body, so that each honeycomb core has self-waterproof effect, and the use of the honeycomb core of the present application can significantly improve the waterproof effect of the hollow floor. At the same time, by coating the waterproof coating inside the honeycomb core body instead of on the outside of the honeycomb core body, the corrosion and wear of the waterproof coating caused by the cast-in-place concrete can be reduced, the damage of the waterproof coating caused by external factors such as high temperature and ultraviolet light can be reduced, the waterproof life of the waterproof coating is prolonged, and the waterproof effect of the honeycomb core of the present application is also enhanced.

[0008] Preferably, the thickness of the waterproof coating is 1mm-3mm.

[0009] By adopting the above technical scheme, on the basis that the waterproof effect of the waterproof coating meets the requirements, the material cost and labor cost are reduced.

[0010] Preferably, the honeycomb core body includes a top plate, a bottom plate, and four side plates surrounding the top plate and the bottom plate, with the through holes formed on the bottom plate.

[0011] By adopting the above technical solution, the spray gun head is inserted through the through hole, so during spraying, the spray gun head is directly facing the top slab, ensuring that most of the waterproof coating is sprayed onto the inner wall of the top slab. Since the hollow core slab mainly relies on the top for waterproofing, the hollow core slab with self-waterproofing function using this application has better waterproofing performance.

[0012] Preferably, the through hole is located at the center of the base plate.

[0013] By adopting the above technical solution, the spraying process is ensured to be uniform, forming a waterproof coating of uniform thickness, thus improving the waterproof effect of the coating.

[0014] Preferably, a sponge ring is bonded to the inner wall of the through hole.

[0015] By adopting the above technical solution, the sponge ring is used to adjust the diameter of the through hole. When using different types of spray gun heads, the sponge ring can maintain contact with the side wall of the spray gun head, ensuring that a certain clamping force is maintained on the side wall of the spray gun head when it is inserted. During spraying, it can also reduce the probability of waterproof coating splashing out from the gap between the spray gun head and the through hole.

[0016] Preferably, the waterproof coating uses a special waterproof and seepage-resistant slurry.

[0017] By adopting the above technical solution, the honeycomb core of this application has superior waterproof performance.

[0018] Secondly, this application provides a waterproof construction method for a honeycomb core with self-waterproofing function, using the following technical solution:

[0019] A waterproofing construction method for a honeycomb core with self-waterproofing function includes the following steps:

[0020] S1: Flip the honeycomb core body so that the through hole faces upward;

[0021] S2: Insert the high-temperature, high-pressure spray gun head containing waterproof coating into the through hole and spray the waterproof coating.

[0022] S3: Wait for the waterproof coating to cool and solidify to form a waterproof layer;

[0023] S4: Flip the honeycomb core body 180° so that the through hole faces downward for installation.

[0024] By adopting the above technical solution, when spraying the waterproof coating, the through holes are set upwards, which not only facilitates the control of the high-temperature and high-pressure spray gun head for spraying, but also allows the waterproof coating to accumulate more on the inner wall of the top plate under the action of gravity, so that the top plate obtains a better waterproof effect, thereby enabling the honeycomb core of this application to obtain a better waterproof effect.

[0025] Preferably, in step S2, the spray gun head is inserted along the axis of the through hole, and the spray gun head is controlled to swing 2-3 times in four directions (forward, backward, left, and right) with the axis of the through hole as the center line to expand the spraying range.

[0026] By adopting the above technical solution and controlling the high-temperature, high-pressure spray nozzle for large-area, uniform spraying, the waterproof coating can be applied not only to the top and side panels but also to the bottom panel. If leakage occurs in the top panel, the waterproof coating on the bottom panel can also provide waterproofing, thus enhancing the overall waterproofing effect of the honeycomb core in this application.

[0027] Preferably, after cooling, a second spraying is performed, and the spraying and cooling steps are repeated 3 to 5 times.

[0028] By adopting the above technical solution, each layer of waterproof coating is allowed to dry completely before the next layer is sprayed, ensuring that the waterproof coating is sprayed evenly and thus has a better waterproof effect.

[0029] Preferably, the through-hole is sealed with concrete mortar after the waterproof coating has cooled and formed.

[0030] By adopting the above technical solution, the probability of concrete flowing into the honeycomb core from the through holes during cast-in-place concrete pouring is reduced.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. This application provides a waterproof coating to each honeycomb core, thus making each honeycomb core waterproof. When using the honeycomb core of this application to build hollow floor slabs, the waterproof performance of the honeycomb core itself can be superimposed with the structural waterproofing of the cast-in-place concrete, thereby improving the waterproof effect of the hollow floor slab. By applying the waterproof coating to the inner wall of the honeycomb core body instead of constructing it on the outside of the honeycomb core body, the wear and corrosion of the waterproof coating by external factors can be reduced, the service life of the waterproof coating can be extended, and the long-term waterproof effect of the honeycomb core can be improved.

[0033] 2. By controlling the spray gun head to swing in four directions (forward, backward, left, and right) 2-3 times around the axis of the through hole, the spraying range of the waterproof coating can be obtained, so that the inner wall of the base plate can also be coated with a waterproof coating, thereby improving the overall waterproof effect of the honeycomb core.

[0034] 3. By spraying the waterproof coating with the through holes facing upwards, it is not only easier to control the high-temperature and high-pressure spray gun head; at the same time, the waterproof coating will accumulate more on the inner wall of the top plate under the action of gravity, so that the top plate can obtain a better waterproof effect, and thus the honeycomb core of this application can obtain a better waterproof effect.

[0040] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0041] This application discloses a honeycomb core with self-waterproofing function. (Refer to...) Figure 1 The self-waterproof honeycomb core includes a honeycomb core body 1 and a waterproof coating 2 applied to the inner wall of the honeycomb core body 1. The honeycomb core body 1 has through holes 121 for the waterproof coating to enter.

[0042] By spraying a waterproof coating 2 onto the inner wall of the honeycomb core body 1 instead of waterproofing the outside of the honeycomb core body 1, waterproofing construction is more convenient and saves construction time. At the same time, because the waterproof coating 2 is located inside the honeycomb core body 1, compared to a waterproof coating 2 located on the outside, it can reduce corrosion and wear caused by cast-in-place concrete, reduce damage to the waterproof coating 2 caused by external factors such as high temperature and ultraviolet radiation, extend the waterproof life of the waterproof coating 2, enhance the waterproof effect of the honeycomb core of this application, and thus improve the waterproof effect of hollow floor slabs using the honeycomb core of this application.

[0043] By pre-drilling through holes 121 in the honeycomb core body 1, waterproof coating is easily sprayed onto the inner wall of the honeycomb core body 1, forming a waterproof coating 2 on the inner wall of the honeycomb core body 1. This gives each honeycomb core a self-waterproofing effect. When using the self-waterproof honeycomb cores of this application to construct hollow floor slabs, the superposition of the waterproofing of the cast-in-place concrete structure and the waterproofing of the honeycomb cores themselves results in a double waterproofing effect for the hollow floor slabs with honeycomb cores. Compared to the original hollow floor slabs that rely solely on the waterproofing of the cast-in-place concrete structure, the waterproofing effect is improved by more than 50%.

[0044] Preferably, the thickness of the waterproof coating 2 is 1mm to 3mm. While ensuring the uniform thickness of the waterproof coating 2 and meeting the waterproof requirements of the honeycomb core, the investment in waterproof coating is minimized to save labor and material costs. This results in the honeycomb core having the best waterproof effect.

[0045] The honeycomb core body 1 includes a top plate 11, a bottom plate 12, and four side plates 13 surrounding the top plate 11 and the bottom plate 12. Through holes 121 are formed in the bottom plate 12. This arrangement is intended so that the top plate 11, serving as the waterproof surface of the hollow floor slab, allows for better waterproofing when the spray gun is aimed at the inner wall of the honeycomb core body 1. This ensures a larger amount of waterproof coating is sprayed onto the inner wall of the top plate 11, guaranteeing optimal waterproofing for the top plate 11, and consequently, a better waterproofing effect for the honeycomb core body 1.

[0046] There can be one or more through holes 121. When there are multiple through holes 121, the spray gun can be inserted into the through holes 121 simultaneously to spray the inner wall of the honeycomb core body 1 at the same time, improving the spraying efficiency. However, this also requires more spray heads and more manual control, making operation inconvenient. This application uses the example of having only one through hole 121, located at the center of the base plate 12, to improve the uniformity of the waterproof coating spraying.

[0047] Furthermore, a sponge ring 14 is installed on the inner wall of the through hole 121. This application only describes the example of the sponge ring 14 being adhered to the inner wall of the through hole 121. The sponge ring 14 is used to adjust the aperture of the through hole 121. When using different types of spray gun heads, the sponge ring 14 can maintain contact with the side wall of the spray gun head, ensuring that a certain clamping force is maintained on the side wall of the spray gun head when it is inserted. During spraying, it can also reduce the probability of waterproof coating splashing out from the gap between the spray gun head and the through hole 121.

[0048] This application also discloses a waterproofing construction method for a honeycomb core with self-waterproofing function. (Refer to...) Figure 2 Waterproofing construction methods for honeycomb cores with self-waterproofing function include:

[0049] S1: Flip the honeycomb core body 1 so that the through hole 121 faces upward;

[0050] S2: Insert the high-temperature and high-pressure spray gun head containing waterproof coating into the through hole 121 and spray the waterproof coating.

[0051] S3: Wait for the waterproof coating to cool and solidify to form a waterproof coating 2;

[0052] S4: Flip the honeycomb core body 1 180° so that the through hole 121 faces downward for installation.

[0053] Reference Figure 3 During waterproofing, the honeycomb core body 1 is first flipped so that the through-hole 121 faces upwards. When spraying, a high-temperature, high-pressure spray gun head is inserted downwards into the through-hole 121, which not only facilitates control of the spraying but also reduces the probability of waterproofing coating dripping or splashing from the through-hole 121. Under the pressure of the high-temperature, high-pressure spray gun head, the waterproofing coating is sprayed radially onto the inner wall of the honeycomb core body 1. The sprayed liquid waterproofing coating then flows under gravity to the inner walls of the top plate 11 and the side plates 13, resulting in the formation of a waterproof coating 2 on the inner walls of the top plate 11 and the side plates 13. When placing the honeycomb cores, the honeycomb core body 1 is flipped 180° back to its original position for subsequent honeycomb core installation. At this point, each honeycomb core has its own waterproofing function, greatly improving the waterproofing effect of the hollow slab with honeycomb cores.

[0054] Reference Figure 3 and Figure 4 Preferably, in step 2, the high-temperature, high-pressure spray gun head is vertically inserted into the through hole 121 along its axis. The high-temperature, high-pressure spray gun head is controlled to swing 2-3 times in each of the four directions (forward, backward, left, and right) around the axis of the through hole 121 to expand the spraying range. By controlling the high-temperature, high-pressure spray gun head to spray evenly over a large area, the waterproof coating can be applied not only to the top plate 11 and side plates 13, but also to the bottom plate 12. If leakage occurs in the top plate 11, the waterproof coating 2 of the bottom plate 12 can also provide waterproofing, which can enhance the overall waterproofing effect of the honeycomb core of this application, thereby enhancing the waterproofing effect of the hollow floor slab with the honeycomb core.

[0055] Furthermore, steps 2 and 3 are configured such that after the single-layer waterproof coating 2 has cooled, a second coat is applied using the spraying method described above. Steps 3 to 5 are repeated. Each layer of waterproof coating 2 is allowed to dry completely before the next layer is applied, ensuring uniform application and achieving a good waterproof effect.

[0056] Furthermore, the waterproof coating can be a liquid waterproof coating such as a polymer waterproof coating, a polymer cement waterproof coating, or a special waterproof and anti-seepage slurry. Because special waterproof and anti-seepage slurries possess characteristics such as high strength, waterproofing and seepage prevention, high temperature resistance, UV resistance, freeze resistance, aging resistance, no shrinkage, oil resistance, and strong adhesion, they have excellent waterproofing, seepage prevention, and moisture-proofing performance on the back side, while also providing secondary repair. Therefore, the waterproof coating of this application uses a special waterproof and anti-seepage slurry, which makes the honeycomb core of this application have superior waterproofing performance.

[0057] After the waterproof coating 2 has cooled and formed, concrete mortar is used to seal the through-hole 121. This reduces the probability that concrete will flow into the honeycomb core through the through-hole 121 during the pouring of concrete.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
