Description

Oblique cylinder floor

Technical Field

The utility model relates to a building engineering technical field, concretely relates to oblique cylinder floor.

Background

With the increasing demand of people for living quality, the indoor environmental comfort of a house has become a main content of building quality, wherein a building floor slab is closely related to indoor sound environmental quality and indoor thermal environmental quality.

For a long time, the sound insulation problem of the floor slab is a problem which is more prominent in response of common people and is also a common problem in building construction. The floor slab is not only a key link of sound insulation, but also an important link of heat insulation in building energy conservation. Researches show that more than 20% of energy consumption is consumed during air-conditioning refrigeration in summer and heating in winter, and the energy consumption is wasted due to dissipation through a floor slab.

Floor sound insulation has two main indexes, namely air sound insulation and impact sound insulation. The air sound insulation follows the mass law, namely, the denser the thick and heavy material, the better the air sound insulation effect is, such as concrete; and impact sound insulation does not follow the mass law, and the softer material impact sound insulation effect that is more is better, and the sound insulation performance of the hard material impact sound of thickness is not good on the contrary. Therefore, it is difficult to satisfy both the air sound insulation and the impact sound insulation.

The traditional floor slab can be divided into a reinforced concrete layer (structural layer) and cement mortar (protective surface layer) from bottom to top, and the thickness of the traditional floor slab is usually 100 mm-120 mm. Has the problems of poor heat preservation and heat insulation performance and poor sound insulation effect.

The existing main sound-insulation and heat-preservation floor slab comprises a floor slab with a sound-insulation heat-preservation layer and a lightweight concrete floor slab, wherein the sound-insulation heat-preservation layer floor slab comprises a reinforced concrete layer (a structural layer), a sound-insulation heat-preservation layer (an additional layer) and a broken stone concrete layer (a rigid protection surface layer); the mode is also a floating floor slab, and the main technology is that light materials (common foam concrete, polyester coiled materials, polystyrene foam boards, rock wool and other similar materials) are laid on a reinforced concrete layer to achieve the effects of heat preservation and sound insulation; because the upper and lower layers are thick rigid layers and the middle layer is a light material layer, when heavy objects and furniture are stacked on the floor slab, the load is stressed unevenly, and the light material in the middle cannot play a role in supporting stress, so that the broken stone concrete layer (rigid protection surface layer) is cracked or broken.

The lightweight concrete floor mainly comprises a reinforced concrete layer and a sound insulation and heat preservation layer (all lightweight concrete); the reinforced concrete and the all-light concrete have large volume weight difference and large expansion and contraction difference, so that the all-light concrete is seriously cracked.

Due to the existence of the middle heat-preservation sound-insulation layer, after the broken stone concrete layer is poured, the broken stone concrete layer is in dispersed point and line contact with the reinforced concrete layer, the direct contact area is very small, heat transfer, absorption and sound separation can be effectively prevented, and meanwhile, the heat-preservation sound-insulation effect is achieved. Meanwhile, because of the heat preservation and sound insulation layer, the cast broken stone concrete layer and the reinforced concrete layer have rigid contact support with uniformly dispersed points and lines, thereby solving the problem that the cast broken stone concrete layer cracks and breaks when the load of the floor slab is concentrated or uneven because the upper and lower parts of the commonly adopted 'floating floor slab' are rigid layers and the middle part is a loose and flexible layer. Moreover, the gaps between the oblique cylinders have certain deformability by combining the characteristics of light materials; when the upper broken stone concrete layer and the bottom reinforced concrete layer are deformed by the cold thermal expansion shrinkage stress and the load deformation stress, the cracking of the floor slab can be prevented.

2. When the broken stone concrete layer is poured, the polyphenyl granule concrete slurry enters the middle of the gap of the adjacent oblique cylinders to form an acceptance supporting angle, and the whole floor slab is distributed according to the oblique cylinders, so that the phenomenon of uneven load stress is avoided, and the problem of fracture and cracking of the broken stone concrete layer is avoided; moreover, the inclined column body is made of light materials with light sound insulation and heat preservation, so that heat transfer between the upper layer and the lower layer is blocked, and the heat preservation and heat insulation effects are achieved; moreover, the inclined surface of the inclined column body can absorb and buffer, and the upper layer (broken stone concrete layer) can generate vibration and sound when being impacted by heavy objects, so that the sound insulation effect of impact sound is good; the inclined column body is made of light materials, has good impact sound insulation effect and plays a role in heat preservation and heat insulation.

3. The utility model discloses the principle of the sound insulation effect of thermal insulation layer does: (1) the inclined column body is made of light materials and has the functions of sound insulation and sound absorption; (2) the broken stone concrete layer on the upper layer of the oblique cylinder body is in plane contact and also in inclined plane contact (is a three-dimensional contact surface), the contact surface of the broken stone concrete layer is larger than the contact surface of a pure plane, and sound can be better absorbed (the sound is spread in a spherical shape, and the peripheral wall body in an acoustic environment test needs to be laid with a silencing cone, so that the principle is the same); (3) the gap between the oblique cylinders combines the characteristics of light materials, has certain deformability, can effectively absorb impact sound to generate vibration, and has better impact sound insulation effect.

4. In the utility model, because of the gaps generated between the oblique cylinders, the upper layer broken stone concrete forms a cone shape with a big top and a small bottom when pouring, and forms cellular point and line stress contact with the bottom layer reinforced concrete layer, and the distribution is uniform, thereby changing the condition that the middle sound insulation heat preservation layer is soft and has no rigid stress; meanwhile, the broken stone concrete is prevented from being broken when the floor slab is loaded.

5. The utility model discloses a batter post body sound insulation heat preservation floor can satisfy the national standard requirement of air sound insulation and impact sound insulation simultaneously, and the accessible increases the effect of sound insulation by the thickness of batter post body.

Retesting was then performed by increasing the thickness of the beveled cylinder. The results show that the high standard requirements disclosed in tables 2 and 4 can be achieved after increasing the thickness of the oblique cylinder.

The utility model discloses a difference of several kinds of batter post shapes is:

(1) the heat preservation and insulation effect is as follows:

under the condition of the same area of the bottom surface of the inclined column body, the more the number of the edges of the bottom surface is, the more the edges of the bottom surface are in contact with the reinforced concrete layer, the heat transfer effect is increased, and the heat preservation and insulation effect is reduced (but the difference is very small).

The circular bottom surface has the largest heat transfer because the gaps between the circles and the adjacent circles present "faces" and the other shapes are simply "lines".

(2) Sound insulation and absorption effects:

under the condition of the same area of the bottom surface of the inclined cylinder, the more the number of the shape sides of the bottom surface is, the better the sound insulation and absorption effect is.

With a rounded bottom surface being the most effective.

(3) Stress supporting effect:

With a rounded bottom surface being the most effective.

The effect sequence combining the above conditions is as follows: the upper surface and the lower surface of the inclined column body are rectangular, the upper surface and the lower surface of the inclined column body are triangular, the upper surface and the lower surface of the inclined column body are hexagonal, and the upper surface and the lower surface of the inclined column body are circular.

The bottom of the oblique cylinder body is provided with flexible fiber cloth, such as flexible glass fiber grids, and other flexible materials can be used, so that a plurality of oblique cylinder bodies are connected into a whole, and the shape of the oblique cylinder bodies connected into a whole is the same. For convenience of description, a structure formed by connecting a plurality of oblique cylinders together is called an integral oblique cylinder. The integral inclined column bodies are arranged in bundles or blocks and mainly aim at the construction of the inclined column bodies.

The construction process of the integral inclined cylinder on the reinforced concrete layer 1 comprises the following steps: after the reinforced concrete layer 1 is finally set, it can be understood that the constructor can walk on the reinforced concrete layer 1. Spraying water on the reinforced concrete layer 1 to wet the reinforced concrete layer 1; then, a layer of concrete is coated on the reinforced concrete layer 1, and then the inclined column bodies (the blocky integral inclined column bodies) which are connected into a whole by the flexible fiber cloth are orderly paved on the reinforced concrete layer 1 coated with the concrete. The area of the coated concrete is consistent with the area of the inclined cylinder which is connected into a whole by the flexible fiber cloth. Thereby the integral inclined column body is fully paved on the reinforced concrete layer 1. Finally, a gravel concrete layer 3 is cast in place on the heat preservation and sound insulation layer 2, and after the gravel concrete layer is cast in place, a flat plate is adopted to vibrate to enable the gravel concrete to be combined with the inclined cylinders tightly (particularly gaps among the inclined cylinders); and thereafter constructed as a conventional floor slab. Thereby completing the pouring of the floor slab. If the integral oblique cylinders are arranged in a bundle, the process is also adopted, and the difference is that when the integral oblique cylinders are laid, the integral oblique cylinders are directly laid on the reinforced concrete layer 1, so that the efficiency is higher in the construction process of the bundle arrangement compared with the block arrangement of the integral oblique cylinders.
