Description

Technical Field

[0001] The present invention relates to the field of swimming pool construction, and particularly to an energy-saving and environment-friendly construction method for the dome-shaped roof of a swimming pool. Background Art

[0002] With the development of society and the improvement of people's living standards, the corresponding demand for fitness and entertainment has increased. Swimming is recognized as the best fitness exercise. In order to meet the swimming needs throughout the year, swimming pools have become a necessary venue. Among them, the dome-shaped roof swimming pools with beautiful shapes, large areas, and a large number of people have won the love of the majority of swimming enthusiasts.

[0003] However, when constructing a swimming pool in the form of a dome-shaped roof, since the specific gravity of concrete is relatively large, it is difficult to construct when making the concrete roof inside the building. Although the patent with the publication number CN110761411A in the prior art discloses a method for pouring large-span suspended spherical dome concrete, there are still problems: one is that a high-pressure spraying device is required to spray the concrete onto the roof, and the other is that due to the relatively large specific gravity of the concrete, the concrete is prone to falling. At the same time, the swimming pool needs to maintain a certain temperature and requires good heat insulation performance to maintain the temperature inside the hall and improve the comfort of the swimmers. Generally, the heat insulation of the existing swimming pool walls is good, but the heat insulation effect of the roof is poor. Due to the high humidity in the swimming pool, the water vapor in the hall rises and condenses on the roof, easily forming water droplets that fall and drip on people, affecting the swimmers and the audience. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an energy-saving and environment-friendly construction method for the dome-shaped roof of a swimming pool, which uses foamed concrete for spraying and pouring. The foamed concrete has a small density and is not easy to fall off, and the

[0005] retained air bubbles can play a role in heat preservation and sound absorption, improving the heat insulation performance of the swimming pool.

[0006] The present invention is achieved through the following technical solutions:

[0007] An energy-saving and environment-friendly construction method for the dome-shaped roof of a swimming pool includes the following steps:

[0008] S1. Make a dome steel frame with steel trusses;

[0009] S2. Install a floor slab at the bottom of the dome steel frame;

[0010] S3. Manufacturing the thermal insulation layer: First, fix the steel mesh at the bottom of the floor slab formwork, then prepare foamed concrete containing bubbles, add the foamed concrete into a high-pressure spraying device, and spray it onto the bottom of the floor slab formwork under high pressure to form a foamed concrete layer. Then, repeatedly roll the foamed concrete with a roller to volatilize the bubbles from the foamed concrete.

[0011] Further, it also includes step S4. Manufacturing the water-absorbing and moisture-permeable layer: Prepare diatomaceous earth, add the diatomaceous earth into a high-pressure spraying device, and spray it onto the bottom of the floor slab formwork under high pressure to form a diatomaceous earth layer.

[0012] Further, when preparing the diatomaceous earth, use diatom mud, building glue powder and lignin fiber, add an appropriate amount of water, and stir evenly.

[0013] Further, the specific manufacturing process of the diatomaceous earth is as follows: 100 parts of diatom mud, 10 - 15 parts of building glue powder, 10 - 15 parts of lignin fiber, add an appropriate amount of water, and stir evenly.

[0014] Further, it also includes step S4. Manufacturing the water-absorbing and moisture-permeable layer: Prepare foamed diatomaceous earth containing bubbles, add the foamed diatomaceous earth into a high-pressure spraying device, and spray it onto the bottom of the floor slab formwork under high pressure to form a foamed diatomaceous earth layer.

[0015] Further, in step S4, add the foamed diatomaceous earth into a high-pressure spraying device, conduct high-pressure spraying to form a thickness of 5 - 10 mm, and then repeatedly roll the foamed diatomaceous earth with a roller to volatilize the bubbles from the foamed diatomaceous earth.

[0016] Further, when preparing the foamed diatomaceous earth, use diatom mud, building glue powder and lignin fiber, add an appropriate amount of water, stir evenly, and then add a foaming agent and stir evenly.

[0017] Further, the specific manufacturing process of the foamed diatomaceous earth is as follows: 100 parts of diatom mud, 10 - 15 parts of building glue powder, 10 - 15 parts of lignin fiber, add an appropriate amount of water, stir evenly, and then add 4 - 6 parts of a foaming agent and stir evenly; the foaming agent is 40% hydrogen peroxide.

[0018] Further, in step S3, add the foamed concrete into a high-pressure spraying device, conduct high-pressure spraying to form a thickness of 10 - 20 mm, and then repeatedly roll the foamed concrete with a roller to volatilize the bubbles from the foamed concrete;

[0019] Repeat the above steps 2 - 3 times.

[0020] Further, the specific manufacturing steps of the foamed concrete are as follows: 100 parts of cement, 5 - 10 parts of aggregate, 10 - 15 parts of building glue powder, 5 - 10 parts of rubber powder, 10 - 15 parts of lignin fiber, 1 - 2 parts of titanate coupling agent. Add an appropriate amount of water, stir evenly, and then add 5 - 8 parts of foaming agent and stir evenly. The foaming agent is 40% hydrogen peroxide.

[0021] The beneficial effects achieved by the present invention compared with the prior art are as follows:

[0022] 1. The insulation layer is made of foamed concrete with a relatively low density. The foamed concrete material can be sprayed into the interior of the roof under a relatively low pressure. Moreover, due to the relatively small specific gravity of the foamed concrete material, it is not easy to fall off the roof. Subsequently, it is repeatedly rolled with a roller to expel as much air as possible from the surface layer of the foamed concrete material. While the surface layer reaches the strength of ordinary concrete, a small amount of air bubbles still remain inside the foamed concrete material, which can play a role in heat preservation and sound absorption, improving the heat preservation performance of the swimming pool.

[0023] 2. The water vapor absorption layer is made of diatomite material. When the water vapor in the swimming pool reaches the roof, the diatomite can absorb part of the water vapor, preventing the water vapor from condensing into water droplets and falling on the roof. Then, when the temperature rises, the absorbed water vapor evaporates and returns to the swimming pool again.

[0024] 3. The water vapor absorption layer is made of foamed diatomite material, which not only absorbs water vapor but also plays a role in heat preservation and sound absorption. Description of the Drawings

[0030] Embodiment 1

[0031] As Figure 1-2 shown, taking the dome roof with a major axis of 98m and a minor axis of 57.5m for building a swimming pool as an example, the present invention discloses an energy-saving and environment-friendly construction method for the dome roof of a swimming pool, including the following steps:

[0032] S1. Use steel trusses to be spliced to make the dome steel frame 1;

[0033] S2. Install the floor bearing plate 2 at the bottom of the dome steel frame 1 by manual cooperation with high-altitude operation machines;

[0034] S3. Make the insulation layer: First, fix a steel mesh at the bottom of the floor bearing plate 2, and then prepare foamed concrete containing bubbles. The specific production steps of the foamed concrete are as follows: Prepare 100 parts of cement, 5 - 10 parts of aggregate, 10 - 15 parts of building glue powder, 5 - 10 parts of rubber powder, 10 - 15 parts of lignin fiber, and 1 - 2 parts of titanate coupling agent. Add an appropriate amount of water, stir evenly, and then add 5 - 8 parts of foaming agent and stir evenly; among them, the foaming agent used is 40% hydrogen peroxide;

[0035] Put the foamed concrete into a high-pressure spraying device, and use high-pressure gas to transport the slurry to the nozzle position. Control the nozzle by the sprayer to carry out high-pressure spraying to form a bubble concrete layer with a thickness of 10 - 20mm. Then use a roller to repeatedly roll on the foamed concrete to drive out as much air as possible from the surface layer part of the foamed concrete material. While the surface layer reaches the strength of ordinary concrete, a small amount of bubbles still remain inside the foamed concrete material.

[0036] Repeat the above steps 2 - 3 times to form a foamed concrete layer 3 with an overall thickness of 50 - 60mm.

[0037] By using the method of the present invention, a thermal insulation layer is made of foamed concrete with a relatively low density. The foamed concrete material can be sprayed into the interior of the roof under a relatively low pressure. And due to the relatively small specific gravity of the foamed concrete material, it is not easy to fall off the roof. Subsequently, the surface layer part of the air in the foamed concrete material is expelled as much as possible by repeatedly rolling with a roller. While the surface layer reaches the strength of ordinary concrete, a small amount of air bubbles still remain inside the foamed concrete material, which can play a role in heat preservation and sound absorption, improve the heat preservation performance of the swimming pool, and greatly reduce the problem of water vapor rising to the roof and condensing into water droplets and falling down.

[0038] Example 2

[0039] Based on Example 1, this example discloses an energy-saving and environment-friendly construction method for the domed roof of a swimming pool. The difference from Example 1 is that it further includes step S4: making a water vapor absorption layer.

[0040] First, prepare diatomaceous earth. Prepare 100 parts of diatom mud, 10 - 15 parts of building glue powder, and 10 - 15 parts of lignin fiber, add an appropriate amount of water, and stir evenly.

[0041] Then, add the diatomaceous earth to a high-pressure spraying device and perform high-pressure spraying on the bottom of the floor slab to form a diatomaceous earth layer. Due to the action of the building glue powder, the diatomaceous earth layer can be bonded to the air bubble concrete layer and will not fall off or crack.

[0042] By using the construction method of the present invention, a water vapor absorption layer is made of diatomaceous earth material. When the water vapor in the swimming pool reaches the roof, the diatomaceous earth can absorb part of the water vapor, avoiding the condensation of water droplets on the roof and falling. Then when the temperature rises, the absorbed water vapor evaporates and returns to the swimming pool again.

[0043] Example 3

[0044] Based on Example 2, this example discloses an energy-saving and environment-friendly construction method for the domed roof of a swimming pool. The difference from Example 2 is that when preparing the diatomaceous earth, 100 parts of diatom mud, 10 - 15 parts of building glue powder, and 10 - 15 parts of lignin fiber are added, an appropriate amount of water is added and stirred evenly, and then 4 - 6 parts of foaming agent are added and stirred evenly. The foaming agent is 40% hydrogen peroxide. Thus, bubble diatomaceous earth is prepared. When the bubble diatomaceous earth layer is sprayed to form, it can not only absorb water vapor, but also has certain functions of heat preservation and sound absorption.
