Description

Technical Field

[0001] The utility model belongs to the technical field of roof slope leveling, and particularly relates to a high-precision roof slope leveling structure suitable for foamed concrete. Background Art

[0002] For parts with waterproofing requirements such as building roofs, in order to meet the requirements of waterproofing and drainage, the slope finding process must be completed first. Slope finding includes architectural slope finding and structural slope finding. According to the functional requirements, most roofs adopt architectural slope finding, that is, lightweight materials such as foamed concrete, granular concrete, and ceramsite concrete are filled on the roof structure board. Foamed concrete is widely used because it can be pumped for construction, has high construction efficiency, and the material is not easy to float or segregate. However, conventional foamed concrete adopts an integral casting method, with a large foaming height difference. Due to the effect of gravity, the slope is not easy to form, and the molding effect is poor. Foamed concrete is made of cement, foaming agent and water, and has high fluidity. It is easy to flow with a slight height difference. It has high precision slope finding requirements, and the construction is difficult and often fails to meet the requirements. Conventional repeated filling and scraper operation affect foaming molding and reduce the quality of foaming. In addition, multiple fillings of foaming increase the construction period and construction cost, and increase resource consumption. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a high-precision roof slope structure suitable for foamed concrete, so as to solve the problem that the foamed concrete used in the existing building slope structure is easy to flow, has poor molding effect, and increases the construction period and construction cost.

[0004] To achieve the above object, the utility model provides a high-precision roof slope structure suitable for foamed concrete, comprising:

[0005] A plurality of equi-height dams are arranged on the inner side of the parapet and above the roof structure.

[0007] According to a specific embodiment of the utility model, the spacing between the multiple equal-height dams is set according to the flow performance of the foamed concrete and the thickness of the foamed layer.

[0008] According to a specific embodiment of the utility model, the contour dam includes a plurality of building blocks, a bonding layer is filled between the plurality of building blocks, and the building blocks are fixedly connected by the bonding layer.

[0013] 1) Compared with the prior art, the utility model provides a high-precision roof slope structure suitable for foamed concrete. The roof slope structure adopts a densely distributed contour dam system to separate the entire foamed concrete into independent filling bodies with smaller slope widths, effectively reducing the height difference of each independent filling body, and ensuring the overall filling elevation control and slope and slope control. The contour dams set according to the slope and the fluidity of the foamed concrete effectively reduce the overall slope height difference of the foamed concrete, reduce the flow caused by the large height difference, and effectively ensure the slope molding quality and the flatness of the slope surface. The construction process of this application is simple, the slope molding effect is good, the labor cost and consumables cost are reduced, it meets the requirements of the green construction concept, and has high economic benefits.

[0023] Example 1

[0024] Additional aspects and advantages of the embodiments of the present invention will be described in part in the following description, and will become apparent from the following description, or will be learned through practice of the embodiments of the present invention. Figure 1-Figure 4 The embodiment of the utility model provides a high-precision roof slope structure suitable for foamed concrete, comprising:

[0025] A plurality of contour dams are arranged inside the parapet 1 and above the roof structure 2. The positions of the plurality of contour dams are arranged according to the slope gradient and the height difference of the slope direction. The plurality of contour dams include a first contour dam 3, a second contour dam 4, a third contour dam 5, a fourth contour dam 6 and a fifth contour dam 7, wherein the fifth contour dam 7 is arranged in the middle of the roof structure 2, the first contour dam 3, the second contour dam 4, the third contour dam 5 and the fourth contour dam 6 are arranged symmetrically on both sides of the fifth contour dam 7 in sequence, and the fourth contour dam 6 is close to the fifth contour dam 7. A first foamed concrete layer 8 is filled between the plurality of contour dams, a second foamed concrete layer 9 is filled above the first foamed concrete layer 8, and a leveling layer 10 is filled above the second foamed concrete layer 9. The height of the fifth contour dam 7 is greater than the height of the fourth contour dam 6, the height of the fourth contour dam 6 is greater than the height of the third contour dam 5, the height of the third contour dam 5 is greater than the height of the second contour dam 4, and the height of the second contour dam 4 is greater than the height of the first contour dam 3.

[0026] In a specific embodiment of the utility model, the spacing between multiple equal-height dams is set according to the flow performance of the foamed concrete and the thickness of the foamed layer, which effectively reduces the overall slope height difference of the foamed concrete, reduces the flow caused by the large height difference, and effectively ensures the slope molding quality and the flatness of the slope surface.

[0027] In a specific embodiment of the utility model, each dam of equal height is a long strip structure, and the top elevations of two symmetrically arranged dams of equal height are the same. The cross-sectional dimensions of the dam of equal height are set according to the thickness of the slope finding layer to ensure stability.

[0028] In a specific embodiment of the utility model, the contour dam includes a plurality of blocks 11, a bonding layer 12 is filled between the plurality of blocks 11, and the blocks 11 are fixedly connected by the bonding layer 12. A bonding layer 12 is filled between the contour dam and the roof structure 2, and the contour dam is fixedly connected to the roof structure 2 by the bonding layer 12. The strength grade of the blocks 11 is the same as that of the foamed concrete.

[0029] Conventional foamed concrete slope leveling adopts setting elevation control points on the structural surface according to the slope, and then filling the foamed concrete according to the control points. Because cast-in-place foamed concrete has high fluidity, it is difficult to form during slope leveling construction. Compared with traditional foamed concrete slope leveling, the utility model separates the overall foamed concrete by setting multiple equal-height dams, reduces the slope height difference, and reduces fluidity. Each equal-height dam is set according to the slope and slope elevation of the roof structure, which ensures the accuracy of the overall slope and slope, and saves material and labor costs. The foaming layer of each independent filling body can be filled continuously, and the foaming layer of the filling layer can be filled continuously, which effectively shortens the construction period.

[0030] Example 2

[0031] The utility model provides a construction method for a high-precision roof slope structure suitable for foamed concrete, comprising:

[0032] (1) After cleaning the roof structure, contour dams are set on the roof structure 2 according to the slope of the slope, including the first contour dam 3, the second contour dam 4, the third contour dam 5, the fourth contour dam 6 and the fifth contour dam 7. Each contour dam is connected to the roof structure layer 2 through a bonding layer 12 using blocks 11 with the same strength grade as the foamed concrete. The contour dams are long strips with the same top elevation. The same is true for other contour dams.

[0033] (2) Adjust the spacing between dams of different heights according to the fluidity of foamed concrete.

[0034] (3) Fill the first foam layer 8 between the dams of equal height. After the first foam layer 8 has a certain strength, fill the second foam layer 9. After the second foam layer 9 has a certain strength, spread the leveling layer 10 on it to complete the foamed concrete slope construction.

[0035] In summary, the utility model provides a high-precision roof slope structure suitable for foamed concrete. The roof slope structure adopts a densely distributed contour dam system to separate the overall foamed concrete into independent filling bodies with smaller slope widths, effectively reducing the height difference of each independent filling body, and ensuring the overall filling elevation control and slope and slope control. The contour dams set according to the slope and the fluidity of the foamed concrete effectively reduce the overall slope height difference of the foamed concrete, reduce the flow caused by the large height difference, and effectively ensure the slope molding quality and the flatness of the slope surface. The construction process of this application is simple, the slope molding effect is good, the labor cost and consumables cost are reduced, it meets the requirements of the green construction concept, and has high economic benefits. It is suitable for various foamed filling slope construction projects with slope requirements, especially those with large slopes.
