Description
Technical Field
[0001] This invention relates to the field of roof pouring, and in particular to a construction device for anti-rheological pouring of sloping roof concrete. Background Technology
[0002] In the construction industry, sloping roofs are widely used in various buildings, including residences and stadiums, due to their excellent drainage performance and aesthetically pleasing design. However, during the concrete pouring process for sloping roofs, traditional pouring techniques consistently face the following challenges due to factors such as the roof's slope angle, the concrete's fluidity, and the construction environment: Currently, concrete pouring for sloping roofs primarily employs two methods: continuous pouring or simple segmented formwork pouring. The former relies on worker experience to control the concrete placement speed and troweling timing. However, concrete on sloping roofs tends to flow along the slope, resulting in uneven concrete thickness and poor surface smoothness. Furthermore, the setting time of the concrete during continuous pouring is difficult to control precisely, easily leading to cold joints due to pouring intervals, which compromises the integrity of the roof structure and its waterproofing performance. The latter method, while using temporary baffles to delineate pouring areas, lacks standardized installation and is not securely fixed to the roof's reinforcing mesh, making it prone to displacement during pouring. This not only fails to effectively suppress concrete rheology but also requires workers to frequently adjust the formwork and troweling, significantly increasing labor intensity. Additionally, the removal of temporary baffles easily leaves joint marks on the roof, affecting subsequent finishing and structural durability.
[0003] Furthermore, existing processes do not consider the dynamic impact of key parameters such as roof slope, concrete slump, and ambient temperature on the pouring effect. The greater the slope, the higher the concrete slump, and the higher the ambient temperature, the stronger the concrete fluidity and the greater the rheological risk. However, existing solutions all use fixed segment spacing or pouring methods, which cannot be adaptively adjusted according to actual working conditions. This results in poor construction quality stability and frequent quality problems such as cracks and hollow areas, making it difficult to meet the requirements of safety and functionality of sloping roof structures. Summary of the Invention
[0004] Based on this, it is necessary to provide a concrete anti-rheology pouring construction device for sloping roofs to address the above-mentioned technical problems. This device breaks away from the drawbacks of traditional "no compartmentation" or "temporary baffle compartmentation". It achieves precise and stable compartmentation by using a partition mesh component fixed to the steel reinforcement frame, thereby structurally suppressing concrete rheology and solving the problem of uneven pouring thickness in traditional methods.
[0005] This invention provides a concrete anti-rheology pouring construction device for sloping roofs, comprising longitudinal reinforcements inclined along the sloping roof and transverse reinforcements perpendicular to the longitudinal reinforcements. The longitudinal reinforcements are arranged in two rows at intervals perpendicular to the sloping roof. Multiple transverse reinforcements are fixed to the lower side of each row of longitudinal reinforcements. The multiple transverse reinforcements are distributed at intervals along the length of the longitudinal reinforcements. The device also includes multiple partition mesh assemblies, which are distributed at intervals along the length of the longitudinal reinforcements. Each pair of adjacent partition mesh assemblies forms a pouring chamber. The upper and lower ends of the partition mesh assembly are respectively close to the upper and lower rows of longitudinal reinforcements. One side of the partition mesh assembly is fixed to the transverse reinforcements. The partition mesh has mesh openings for concrete flow.
[0006] In one embodiment, concrete is poured sequentially into multiple pouring chambers starting from the lowest point of the sloping roof and moving upwards.
[0007] In one embodiment, the spacing between pouring sections is calculated based on the roof slope, concrete slump, and ambient temperature, thereby determining the spacing between two adjacent partition mesh components.
[0008] In one embodiment, the formula for calculating the spacing between the casting hoppers is:
[0009] in, Indicates the slope of a sloping roof. Indicates the slump of concrete. Indicates ambient temperature. For correction factor, It is a function of temperature.
[0010] In one embodiment, the separator assembly includes a mesh body and connectors; the connectors are provided in multiple pairs, and the multiple pairs of connectors are spaced apart along the length direction of the mesh body. The two connectors in the same pair are located on the upper and lower sides of the mesh body, respectively, and are respectively hooked onto two horizontal ribs that are opposite each other.
[0011] In one embodiment, the upper end of the mesh body is provided with multiple slots, the multiple slots are distributed at intervals along the length direction of the mesh body, and each slot is fitted with a longitudinal rib located in the upper row.
[0012] In one embodiment, the surface of the mesh body is provided with a plurality of mesh openings, and the mesh openings closer to the sloping roof have smaller apertures.
[0013] In one embodiment, one end of the connector is connected to the mesh body, and the other end of the connector is bent toward the sloping roof and parallel to the mesh body.
[0014] The aforementioned anti-rheology concrete pouring device for sloping roofs consists of longitudinal reinforcements inclined along the sloping roof and transverse reinforcements perpendicular to the longitudinal reinforcements forming a grid-like framework. The longitudinal reinforcements are arranged in two rows perpendicular to the sloping roof, with multiple transverse reinforcements fixed to the lower side of each row of longitudinal reinforcements, providing structural support for the entire device and adapting to the sloping shape of the roof. Multiple partition mesh components are distributed at intervals along the length of the longitudinal reinforcements, with their upper and lower ends close to the upper and lower rows of longitudinal reinforcements and one side fixed to the transverse reinforcements. This forms a stable connection with the steel reinforcement framework and divides the sloping roof into independent pouring units. In addition to its "flow" function, the mesh openings of the partition mesh can also achieve a balance between "resisting rheology" and "promoting bonding," preventing excessive flow of concrete along the slope while allowing concrete from adjacent pouring sections to seep through the mesh, ensuring the continuity of the overall structure. Breaking away from the drawbacks of traditional "no compartmentation" or "temporary baffle compartmentation," this method achieves precise and stable compartmentation through a partition mesh component fixed to the steel reinforcement frame. This structurally suppresses concrete rheology and solves the problem of uneven thickness in traditional pouring. The coordinated design of the partition mesh with the longitudinal and transverse reinforcement eliminates the need for additional complex support structures, adapts to the sloping characteristics of roofs, avoids the risk of temporary component displacement, and the mesh design balances the needs of concrete flow and rheology resistance. This ensures that concrete fills all areas during pouring while preventing quality problems caused by excessive flow. It also provides a channel for the bonding of new and old concrete during subsequent compartment pouring, improving the overall structural integrity and solving the problem of cold joints in traditional monolithic pouring.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] The following is combined Figures 1 to 4 This invention describes a concrete anti-rheology pouring construction device for sloping roofs 10.
[0020] In one embodiment, a concrete anti-rheology pouring construction device for a sloping roof 10 includes longitudinal reinforcement 20 inclined along the sloping roof 10 and transverse reinforcement 30 perpendicular to the longitudinal reinforcement 20. The longitudinal reinforcement 20 is arranged in two rows perpendicular to the sloping roof 10. Multiple transverse reinforcement 30 are fixed to the lower side of each row of longitudinal reinforcement 20. The multiple transverse reinforcement 30 are distributed at intervals along the length of the longitudinal reinforcement 20. The device also includes multiple partition mesh components 100, which are distributed at intervals along the length of the longitudinal reinforcement 20. Each pair of adjacent partition mesh components 100 forms a pouring chamber. The upper and lower ends of the partition mesh component 100 are close to the upper and lower rows of longitudinal reinforcement 20, respectively. One side of the partition mesh component 100 is fixed to the transverse reinforcement 30. Mesh openings 111 are provided on the partition mesh for concrete flow.
[0021] The aforementioned concrete anti-rheology pouring construction device for the sloping roof 10 has a grid-like skeleton formed by longitudinal reinforcement 20 inclined along the sloping roof 10 and transverse reinforcement 30 perpendicular to the longitudinal reinforcement 20. The longitudinal reinforcement 20 is arranged in two rows perpendicular to the sloping roof 10. Multiple transverse reinforcement 30 distributed along the length of the longitudinal reinforcement 20 are fixed on the lower side of each row of longitudinal reinforcement 20, providing structural support for the entire device and adapting to the sloping shape of the sloping roof 10. Multiple partition mesh components 100 are distributed at intervals along the length of the longitudinal reinforcement 20, with their upper and lower ends close to the upper and lower rows of longitudinal reinforcement 20 and one side fixed to the transverse reinforcement 30. This forms a stable connection with the steel reinforcement skeleton and divides the sloping roof 10 into independent pouring units. The mesh 111 of the partition mesh not only serves the function of "flow" but also achieves a balance between "resisting rheology" and "promoting bonding". It prevents the concrete from flowing excessively along the slope while allowing the concrete of adjacent pouring sections to partially penetrate through the mesh 111, ensuring the continuity of the overall structure. Breaking away from the drawbacks of traditional "no compartmentation" or "temporary baffle compartmentation," precise and stable compartmentation is achieved through the partition mesh component 100 fixed to the steel reinforcement frame. This structurally suppresses concrete rheology and solves the problem of uneven thickness in traditional pouring. The coordinated design of the partition mesh with the longitudinal reinforcement 20 and transverse reinforcement 30 eliminates the need for additional complex support structures. It adapts to the inclined characteristics of the sloping roof 10, avoiding the risk of temporary component displacement. The mesh 111 design takes into account both concrete flow and rheology resistance requirements, ensuring that concrete can fill each area during pouring while preventing quality problems caused by excessive flow. At the same time, it provides a channel for the bonding of new and old concrete during subsequent compartment pouring, improving the overall structural integrity and solving the problem of cold joints in traditional integral pouring.
[0022] In one embodiment, concrete is poured sequentially into multiple pouring chambers starting from the lowest point of the sloping roof 10 and moving upwards.
[0023] Specifically, the lowest point of the sloping roof 10 is where the gravitational potential energy of the concrete is lowest. Pouring from this point can prevent the concrete from accumulating downwards along the slope due to gravity, reducing the problems of accumulation in low-lying areas and leakage in high-lying areas. When pouring upwards in sections, the concrete of the already poured sections can form a "temporary retaining wall" to provide lateral support for the concrete of the previous section, further suppressing rheology, while also facilitating workers to accurately vibrate and smooth the surface of individual pouring sections.
[0024] It avoids the problem of concrete "self-flowing" in traditional monolithic casting. By controlling the concrete in a "container-by-container" sequence, it achieves uniform distribution of concrete in each casting chamber, ensuring consistent roof thickness. The small volume of each casting chamber allows workers to concentrate on controlling the vibration quality, avoiding problems of insufficient compaction caused by excessively large casting areas, reducing defects such as hollow areas and cracks. It also eliminates the need for frequent formwork adjustments, reducing the labor intensity of workers. Compared with traditional segmented formwork casting, the construction process is more orderly.
[0025] In one embodiment, the spacing between pouring sections is calculated based on the slope of the sloping roof 10, the concrete slump, and the ambient temperature, thereby determining the spacing between two adjacent partition mesh components 100.
[0026] Specifically, the formula for calculating the spacing between pouring troughs is as follows:
[0027] in, This indicates a 10-degree slope for the roof. Indicates the slump of concrete. Indicates ambient temperature. For correction factor, It is a function of temperature.
[0028] It should be noted that the greater the slope, the greater the gravitational component of the concrete sliding down the roof, and the higher the risk of rheology. The spacing between the pours needs to be reduced to shorten the concrete flow path. The greater the slump, the stronger the concrete fluidity, and the easier it is to spread along the slope. The spacing between the pours needs to be reduced to limit its flow range. The higher the temperature, the longer the initial setting time of the concrete, the longer the fluidity is maintained, and the greater the possibility of rheology. The spacing between the pours needs to be adjusted to adapt to the effect of temperature on the concrete performance.
[0029] This method breaks away from the traditional "one-size-fits-all" compartmenting approach, enabling adaptive compartmenting based on working conditions. It solves the problem of unstable construction quality under different slopes, concrete mix ratios, and ambient temperatures. The scientifically parameter-correlated compartmenting method avoids concrete rheology caused by excessively large compartment spacing or low construction efficiency caused by excessively small compartment spacing, achieving a "quality and efficiency balance." It provides a theoretical basis for subsequent quantitative calculation of compartment spacing, enabling construction to shift from "experience-driven" to "data-driven," thus improving the scientific nature and reliability of the process.
[0030] In addition, the correction factor With temperature function The design makes the formula flexible and adaptable, covering various working conditions such as flat slopes, steep slopes, high temperatures, and low temperatures, and has a wide range of applications.
[0031] In one embodiment, the separator assembly 100 includes a mesh body 110 and connectors 120. Multiple pairs of connectors 120 are provided, and the multiple pairs of connectors 120 are spaced apart along the length direction of the mesh body 110. Two connectors 120 in the same pair are located on the upper and lower sides of the mesh body 110, respectively, and are respectively hooked onto two opposite horizontal ribs 30.
[0032] Specifically, multiple pairs of connectors 120 are provided and distributed at intervals along the length of the mesh body 110. Each pair of connectors 120 is located on the upper and lower sides of the mesh body 110 and corresponds one-to-one with the upper and lower horizontal ribs 30. The mesh body 110 can be directly fixed to the horizontal ribs 30 by means of "hanging" (such as L-shaped hooks or buckles) without welding or binding. The interval distribution of multiple pairs of connectors 120 ensures that the connection points between the mesh body 110 and the horizontal ribs 30 are uniform, avoids excessive local stress that may cause the mesh to deform, and ensures the stability of the compartment dimensions.
[0033] By adopting the "hook-on" connector 120, the rapid installation of the partition mesh component 100 and the steel mesh is achieved. Compared with the traditional binding and fixing of temporary baffles, the installation efficiency is higher and the construction time is reduced. The matching design of connector 120 and horizontal reinforcement 30 ensures a firm connection. There is no risk of mesh displacement or detachment during the pouring process, which solves the problem of unstable fixing of traditional segmented formwork. The modular design allows the mesh body 110 and connector 120 to be prefabricated, ensuring quality control, avoiding dimensional errors in on-site processing, and improving the accuracy of compartmentation.
[0034] In one embodiment, the upper end of the mesh body 110 is provided with a plurality of slots 112, the plurality of slots 112 are distributed at intervals along the length direction of the mesh body 110, and each slot 112 is fitted with a longitudinal rib 20 located in the upper row.
[0035] Specifically, the size of the slot 112 is adapted to the diameter of the longitudinal rib 20, which ensures that the longitudinal rib 20 can be inserted smoothly and avoids the mesh body 110 from shifting left and right due to excessive gap. Combined with the "lateral fixing" of the connector 120 and the transverse rib 30, the cooperation between the slot 112 and the longitudinal rib 20 realizes the "dual positioning" of the mesh body 110 in both longitudinal and transverse directions, ensuring its accurate installation position on the sloping roof 10.
[0036] The dual positioning design significantly improves the installation accuracy of the partition mesh component 100, avoids the offset of the mesh body 110 caused by the tilt of the sloping roof 10, ensures consistent spacing between each pouring section, and solves the problem of uneven dimensions in traditional sections. The interlocking structure of the slot 112 and the longitudinal reinforcement 20 further enhances the connection strength between the mesh body 110 and the steel reinforcement skeleton. It can withstand the lateral pressure of concrete during pouring, prevents mesh deformation, and ensures the stability of the section shape. No additional measurement and positioning is required during installation. Alignment can be quickly achieved simply by the cooperation of the slot 112 and the longitudinal reinforcement 20, simplifying the construction process and reducing the difficulty of operation for workers.
[0037] In one embodiment, the surface of the mesh body 110 is provided with a plurality of mesh openings 111, and the mesh openings 111 closer to the sloping roof 10 have smaller apertures.
[0038] Specifically, the area near the sloping roof 10 (i.e., the lower part of the pouring compartment) is a critical area where concrete is prone to flow. The small-diameter mesh 111 can enhance the "blocking effect" on the concrete and inhibit the concrete from flowing down the slope. The area away from the sloping roof 10 (i.e., the upper part of the pouring compartment) has a larger mesh 111, which allows the concrete from the adjacent pouring compartment (the previous compartment) to partially penetrate into this compartment during pouring, achieving a tight bond between the old and new concrete, and facilitating the removal of air bubbles during vibration.
[0039] The gradient mesh 111 design achieves a balance between "flow restriction and bonding promotion," solving the problems of "either insufficient flow restriction or poor bonding" caused by the uniform aperture of traditional meshes, while ensuring concrete density. The small apertures at the bottom effectively restrict concrete flow, ensuring uniform concrete thickness within the pouring chamber, while the large apertures at the top promote bonding between new and old concrete, reducing cold joints and improving the overall integrity and waterproofing performance of the roof structure. The gradient distribution of the mesh 111 does not require additional component costs and can be achieved through prefabrication, balancing functionality and economy.
[0040] In one embodiment, one end of the connector 120 is connected to the mesh body 110, and the other end of the connector 120 is bent toward the sloping roof 10 and parallel to the mesh body 110.
[0041] Specifically, the bending direction is aligned with the inclination angle of the sloping roof 10, so that when the connector 120 contacts the horizontal reinforcement 30, it can "fit and hook" rather than be subjected to vertical force, thus avoiding breakage of the connector 120 due to the shear force generated by the inclination angle. The design of "parallel to the mesh body 110" ensures that the force direction of the connector 120 is consistent with that of the mesh body 110, so that the mesh body 110 can evenly bear the lateral pressure of the concrete during pouring, avoiding local stress concentration that could lead to mesh deformation.
[0042] The curved structure adapts to the sloping shape of the roof 10, making the connection between the connector 120 and the horizontal reinforcement 30 more secure. It can withstand greater lateral pressure from the concrete during pouring, solving the problem of easy loosening and breakage of the traditional straight rod connector 120. The parallel design ensures that the mesh body 110 is subjected to uniform force, avoiding dimensional deviations in the pouring chamber caused by local deformation, further improving the stability of construction quality. The curved structure is easy to process and can be prefabricated as an integral part with the connector 120 without increasing the installation difficulty. At the same time, it improves the durability of the components and is suitable for sloping roofs 10 with different tilt angles.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
