Description

Technical Field

[0001] This utility model relates to the field of sloping arch roof construction technology, specifically to a sloping arch roof structure. Background Technology

[0002] In the construction of traditional sloping arched roofs, the conventional practice is to construct them in the following order: "foundation layer - waterproof layer - insulation layer - concrete protective layer - metal roof support system".

[0003] The construction of sloping arched roofs requires solving key technical challenges such as formwork erection, concrete pouring, and subsequent installation of the metal roof support system. Its construction drawbacks are mainly reflected in structural stability and construction quality.

[0004] For example, two measures are usually taken during the construction of the foundation layer:

[0005] (1) Double-layer formwork; the formwork is difficult to erect, the positioning accuracy is high, the material and labor costs increase significantly, the process is complicated, the construction time is long, the flow and vibration of concrete are restricted, and the vibration may not be dense enough, which may lead to water seepage in the roof structure.

[0006] (2) Single-layer formwork; During the concrete pouring process, the horizontal component of the force generated by its own weight increases. If the slump is not properly controlled (such as excessive slump), the concrete will flow down the slope, resulting in insufficient thickness of the upper concrete and local accumulation at the bottom. The surface flatness deviation can reach 10~20mm.

[0007] Alternatively, in the case of a metal roof support system, the metal frame and keel need to be fixed to the supports, purlins and metal roof system by post-installed chemical bolts; because the curvature of the sloping roof will cause uneven heat distribution, resulting in differences in the thickness of the insulation layer in different areas, generally in the range of 120~140mm. The traditional fixed support structure cannot flexibly adapt to the changes in the thickness of the insulation layer, making it difficult to control the elevation of the concrete protective layer, affecting the flatness and load transfer reliability of the metal roof keel support system;

[0008] Furthermore, the lack of visual markings for the pre-embedded positions of metal roof supports makes it easy for anchor bolts to deviate from the preset positions during subsequent installation, potentially causing them to be accidentally driven into the insulation layer, resulting in support fixation failure and a risk of roof structure loosening. In the absence of visual markings, the post-installed anchor bolts may even penetrate the waterproof layer during construction, causing waterproofing failure and potential leakage.

[0009] Therefore, to solve the above problems, a sloping roof structure is needed that can optimize the construction scheme of existing technologies, thereby solving one of the technical difficulties such as formwork erection, concrete pouring and subsequent installation of metal roof support system, and improving the construction quality of sloping roof structure. Utility Model Content

[0010] In view of this, the purpose of this utility model is to overcome the defects in the prior art, provide a sloping roof structure, optimize the construction scheme of the prior art, and solve one of the technical problems such as formwork support, concrete pouring and subsequent installation of metal roof support system, thereby improving the construction quality of sloping roof structure.

[0011] The sloping arc roof structure of this utility model includes a base layer, a waterproof layer, a thermal insulation layer, a concrete protective layer, and a metal roof support system arranged sequentially from bottom to top; the base layer is provided with a concrete interception structure, which includes an interception net, the interception net being inclined from top to bottom toward the lower part of the roof, or the interception net being arranged parallel to the vertical direction;

[0012] The insulation layer has functional holes, and the functional holes have support structures. The support structures include a support base, a movable base, and a support frame.

[0013] In use, the movable seat is placed in the functional hole, and the support seat is driven to rise or fall on the movable seat; the top surface of the support seat is adjusted to move closer to or further away from the waterproof layer as a reference surface, and is locked in a preset position.

[0015] The metal roof support system includes anchor bolts, which are embedded in a concrete protective layer between two of the functional reinforcing bars.

[0016] Furthermore, a protective pad is provided at the bottom of the support base.

[0017] Furthermore, the protective pad is a rubber pad with a height exceeding 3 mm.

[0019] The inner surface of the adjustment cavity is provided with an internal thread, and the outer surface of the movable seat is provided with an external thread. The adjustment block of the movable seat extends into the adjustment cavity and engages with it in a threaded manner to adjust the height for use, so that the reference surface of the support seat is close to or far away from the waterproof layer.

[0020] Furthermore, the bottom of the functional rib is provided with an anti-detachment block, and a strip groove along the inclined direction of the sloping roof is opened on the reference surface. The functional rib extends downward through the strip groove into the adjustment cavity and is limited by the adjustment cavity through the anti-detachment block.

[0021] Furthermore, the main frame is a double-layer steel mesh in the shape of a "well" and there are several functional bars. The functional bars connect and support the nodes of the double-layer steel mesh in the vertical direction. The main frame is located in the middle of the length direction of the functional bars.

[0022] Furthermore, the supporting seats and movable seats that cooperate are in several groups that correspond to the number of functional ribs. In use, the groups of supporting seats and movable seats limit the functional ribs one by one, so that each functional rib is limited in its corresponding adjustment cavity.

[0023] Furthermore, the circumferential outer surface of the anti-detachment block is a convex curved surface, and the anti-detachment block abuts against the inner surface of the adjustment cavity through the curved surface.

[0024] Furthermore, the support base has a feed hole along its height direction.

[0045] Figure 7 This is a schematic diagram of the basic layer of this utility model. Detailed Implementation

[0046] Figures 1 to 7 The figure shows a schematic diagram of the structure of this utility model. The sloping roof structure in this embodiment includes a base layer 001, a waterproof layer 002, a thermal insulation layer 003, a concrete protective layer 004, and a metal roof support system 005 arranged sequentially from bottom to top.

[0047] In this embodiment, a concrete interception structure is provided within the base layer 001. This structure includes an interception mesh 102 and a mesh limiting component. The mesh structure of the interception mesh 102 has a relatively large roughness, which increases the contact area with the next layer of poured concrete, increases the connection strength with the next layer of poured concrete, improves overall consistency, and effectively resists the diagonal thrust along the roof, preventing separation between adjacent concrete layers. In this design, the interception mesh 102 is preferably galvanized steel wire mesh, which has certain strength and toughness, and can resist pressure and shear forces. It should be understood that the smaller the mesh size of the interception mesh 102, the better the concrete interception effect, and the higher the strength of the interception mesh 102, the stronger its ability to resist concrete.

[0048] In this embodiment, the intercepting net 102 is set on the bottom formwork 101 of the foundation layer 001 by an intercepting net limiting component, and multiple sets of concrete intercepting structures are arranged along the height direction of the roof; so that during pouring, the concrete segments of the foundation layer 001 between adjacent concrete intercepting structures are poured one by one from bottom to top; specifically, each piece of the intercepting net 102 is set on the bottom formwork 101 by a number of intercepting net limiting components arranged along the width direction of the roof; improving installation reliability, ensuring stress reliability, and preventing the concrete of the steeply sloping curved roof from falling.

[0049] In this embodiment, the intercepting net 102 is inclined from top to bottom towards the lower part of the roof, that is, the intercepting net 102 is in the same direction of inclination as the roof, and the inclination angle does not exceed 10°. This angle is the angle between the intercepting net 102 and the vertical direction, or the intercepting net 102 is set parallel to the vertical direction. The inclination or vertical setting of the intercepting net 102 allows for the formation of a wedge-shaped first-pour section when pouring concrete in stages. When pouring subsequent concrete, it can increase the ability to retain concrete, improve the connection strength with the later-poured concrete, and improve the overall consistency. In this solution, the vertical setting of the intercepting net 102 can eliminate the need for auxiliary tools. It can be directly arranged vertically during construction, reducing construction difficulty and speeding up the construction progress. It should be understood that if the intercepting net 102 cannot be guaranteed to be completely vertical during actual construction, it can be slightly inclined towards the side of the later-poured concrete, which will not be elaborated here.

[0050] In this embodiment, the intercepting net limiting component includes a fixing plate 103 set on the bottom formwork 101, and a limiting steel bar 104 set on the fixing plate 103 that is driven to swing toward the roof or the bottom of the roof. The swing axis of the limiting steel bar 104 and the fixing plate 103 is parallel to the width direction of the roof, and the swing axis is located close to the bottom formwork 101. The intercepting net 102 is set on the limiting steel bar 104. That is, the intercepting net 102 is driven to swing on the bottom formwork 101 through several intercepting net limiting components. The intercepting net 102 can be driven to swing toward the side of the first-poured concrete or the side of the later-poured concrete, so that resistance to the cast-in-place concrete can be actively applied during construction, further limiting the shape of the cast-in-place concrete after curing, further improving the ability of the cast-in-place concrete to form the above-mentioned wedge-shaped first-poured section, thereby ensuring the integrity and consistency of the sloping roof foundation layer 001.

[0051] In this embodiment, the fixing piece 103 is integrally injection molded from modified polypropylene. During use, the fixing piece 103 is fixed to the bottom mold 101 using staples, making construction simple and convenient, improving construction quality, and offering relatively low cost and greater economic efficiency. The position of the fixing piece 103 is determined based on existing calculation models, such as commonly used BIM models, improving the installation accuracy of the fixing piece 103 and thus ensuring the installation accuracy of the interception net 102. The top of the fixing piece 103 has a connecting portion with limiting holes for limiting reinforcing bars 104 parallel to the roof width direction. The limiting reinforcing bars 104 are in the shape of a hoop, with their bottoms passing through the limiting holes and being driven to swing on the connecting portion. The top of the limiting reinforcing bars 104 closes to form a long, narrow hoop structure. The interception net 102 is connected to the side of the limiting reinforcing bars 104 near the high point of the roof, further improving the connection reliability between adjacent concrete segments, enhancing the consistency of the sloping roof foundation layer 001, effectively suppressing the flow of post-poured concrete, and ensuring construction quality.

[0052] In this embodiment, the base layer 001 is also pre-embedded with a top steel mesh 105 corresponding to the top of the intercepting net 102 and a bottom steel mesh 106 corresponding to the bottom of the intercepting net 102. The intercepting net 102 is connected to the top steel mesh 105 and the bottom steel mesh 106 through the intercepting net limiting component. This allows the double-layer steel mesh, the intercepting net 102, and the intercepting net limiting component in the base layer 001 to form a multi-integrated assembly structure, which can effectively improve the density of the concrete structure of the sloping roof. For concrete segments poured section by section, the stress is distributed by the overall structure during each concrete pour, and the anti-slip ability is efficiently improved. It can better control the flatness and density of the concrete in each segment and the connected segments. Furthermore, with the structure and method of this solution, the spacing between adjacent intercepting net 102 pieces can be designed to be larger, which is especially suitable for sloping roofs with large slopes, such as R34566, R38779, R46281, etc., to further improve economy.

[0053] In this embodiment, the top reinforcing mesh 105 and the bottom reinforcing mesh 106 are limited by the limiting reinforcing bar 104, so that the intercepting mesh 102, the top reinforcing mesh 105 and the bottom reinforcing mesh 106 are connected, and the cross section of the intercepting mesh 102, the top reinforcing mesh 105 and the bottom reinforcing mesh 106 after connection is approximately "I" shaped; the structural stability is better, wherein the bottom reinforcing mesh 106 is located on top of the fixing plate 103, the swing axis of the fixing plate 103 and the limiting reinforcing bar 104 is located between the bottom reinforcing mesh 106 and the bottom formwork 101, the reinforcing mesh is set on the limiting reinforcing bar 104 and is located above the bottom reinforcing mesh 106, and the top reinforcing mesh 105 is limited by the limiting reinforcing bar 104 and is located above the connecting mesh. During construction, the fixing plate 103 is first set on the bottom formwork 101, and then the limiting steel bar 104 is set on the fixing plate 103. In this state, the top of the limiting steel bar 104 is open. Then, the bottom steel mesh 106, the intercepting mesh 102 and the top steel mesh 105 are set on the limiting steel bar 104 from bottom to top. Then, the top opening of the limiting steel bar 104 is closed, and the entire load-bearing system is fully connected.

[0054] In this embodiment, the top reinforcing mesh 105 has a top longitudinal reinforcing bar corresponding to the limiting reinforcing bar 104, and the bottom reinforcing mesh 106 has a bottom longitudinal reinforcing bar corresponding to the limiting reinforcing bar 104; the top reinforcing mesh 105 also includes a top transverse reinforcing bar that is perpendicularly connected to the top longitudinal reinforcing bar corresponding to the position of the limiting reinforcing bar 104, and the top transverse reinforcing bar is located on the side of the limiting reinforcing bar 104 near the high point of the roof; the bottom reinforcing mesh 106 also includes a bottom transverse reinforcing bar that is perpendicularly connected to the bottom longitudinal reinforcing bar corresponding to the position of the limiting reinforcing bar 104, and the bottom transverse reinforcing bar is located on the side of the limiting reinforcing bar 104 near the high point of the roof. The top reinforcing mesh 105 and the bottom reinforcing mesh 106 have the same mesh shape, both being square reinforcing meshes. During construction, the positioning of the limiting reinforcing bar 104 is not only close to the top reinforcing bar connection nodes of the top longitudinal and top transverse reinforcing bars in the top reinforcing mesh 105, but also close to the bottom reinforcing bar connection nodes of the bottom longitudinal and bottom transverse reinforcing bars in the bottom reinforcing mesh 106. Furthermore, the limiting reinforcing bar 104 faces the bottom edge of the sloping roof, and the top and bottom reinforcing bar connection nodes face the top edge of the sloping roof. This enhances the interception capacity during concrete pouring.

[0055] In this embodiment, the waterproof layer 002 and the thermal insulation layer 003 are both selected from existing technologies that are suitable for this solution, and it is advisable to complete the intended function. Further details will not be provided here.

[0056] In this embodiment, functional holes are pre-reserved on the insulation layer 003. It should be understood that a number of functional holes are pre-reserved on the insulation layer 003 according to the construction design, or they may be opened on-site during construction, depending on the actual construction. Further details will not be provided here. The support structure corresponds to the number of functional holes and is arranged in a one-to-one relationship.

[0057] In this embodiment, the support structure includes a support base 1, a movable base 2, and a support frame 3.

[0058] In this embodiment, the movable seat 2 includes a disc-shaped base plate and an adjusting block protruding upward from the center of the base plate. The adjusting block is cylindrical and has external threads. The movable seat 2 is used as a driving component and a bottom support component. When in use, it is built into the functional hole and supported by the waterproof layer 002. In actual use, the movable seat 2 can be designed as a hollow structure filled with concrete, or it can be designed as a hollow structure. When the concrete protective layer 004 is poured afterward, the hollow structure is filled with concrete. This will not be elaborated further here.

[0059] In this embodiment, the bottom of the movable seat 2 is also provided with a protective pad 4. The thickness of the protective pad 4 exceeds 3mm. The protective pad 4 is preferably a 5mm rubber pad, which has a certain elasticity and deformation capacity, and has the advantages of good stability and long service life. One of the design purposes of the protective pad 4 is to protect the bottom waterproof layer 002 and prevent damage from rigid contact. Another design purpose is to be suitable for the construction structure of sloping roofs. It has a certain elasticity and deformation capacity, strong adaptability, and can improve the setting stability of the overall support structure, thereby ensuring the quality of the concrete protective layer 004 poured later.

[0060] In this embodiment, the support base 1 includes a top plate and a cylindrical body connected to the bottom of the top plate. The top surface of the top plate in the support base 1 serves as a reference surface, which is used to support the support frame 3. Specifically, the support frame 3 has a main frame 5 supported by the reference surface and functional ribs 6 connected to the main frame 5. The cylindrical body and the top plate form an open-topped adjustment cavity. An internal thread adapted to the adjustment block is provided on the inner surface of the cylinder, so that when in use, the adjustment block extends into the adjustment cavity of the cylinder and the threaded engagement adjusts the usage height, so that the reference surface of the support base 1 is close to or away from the waterproof layer 002 and is locked in a preset position, so that the usage height of the support frame 3 set on the reference surface is adjustable.

[0061] In this embodiment, a strip groove 7 is opened on the reference surface along the inclined direction of the sloping roof, that is, the strip groove 7 is opened on the top plate along the inclined direction of the sloping roof; the strip groove 7 is used to limit the swing of the functional rib 6 in the support frame 3 along the inclined direction of the sloping roof, so as to make it suitable for the thickness change of the insulation layer 003 in the sloping roof, which is beneficial to control the elevation of the concrete protective layer 004. Specifically, due to the characteristics of sloping roofs and the varying thickness of the insulation layer 003, the pre-embedded locations of the support structures may have a front-lower or rear-higher configuration, making it difficult to apply ordinary fixed supports. While height-adjustable supports can be used, if the height difference exceeds a certain dimension, especially under the sloping roof construction conditions in this scheme, the overall structural limitations of the support frame 3 can lead to issues such as weld point cracking or the support components not being supported on the waterproof layer 002. This makes it difficult to effectively position the reinforcing mesh in the post-cast concrete protective layer 004, resulting in poor construction quality of the concrete protective layer 004. The height-adjustable support structure can only be used as an independent fulcrum in the form of point support, with poor overall connectivity, limited support capacity, poor economy, and relatively high cost, making it difficult to apply on a large scale. This solution, by creating a strip groove 7, allows the support frame 3 to be driven to swing within the combined structure of the support base 1 and the movable base 2. This allows for adjustment of the operating angle of the support frame 3 to accommodate different thicknesses of the insulation layer 003 and different angles of the sloping roof, effectively controlling the elevation of the concrete protective layer 004. The support frame 3 has several functional ribs 6, and the corresponding support base 1 and movable base 2 consist of several groups matching the number of functional ribs 6. In use, the groups of support base 1 and movable base 2 limit the functional ribs 6 one by one, so that each functional rib 6 is limited within its corresponding adjustment cavity. This reliably and effectively positions the support frame 3 within the functional holes created in the insulation layer 003, satisfying both the requirements for support strength and the needs for height and angle adjustment.

[0062] In this embodiment, the bottom of the functional rib 6 is provided with an anti-detachment block 8. The functional rib 6 extends downward through the strip groove 7 into the adjustment cavity and is limited by the adjustment cavity through the anti-detachment block 8. The anti-detachment block 8 is disc-shaped, and the outer circumferential surface of the anti-detachment block 8 is a convex curved surface. The anti-detachment block 8 abuts against the inner surface of the adjustment cavity through the curved surface. The design of the anti-detachment block 8 is to improve the stress consistency of the overall structure. The curved shape of the outer circumferential surface of the anti-detachment block 8 ensures that it is always in line with the inner surface of the adjustment cavity, which improves the limiting ability of the support frame 3, effectively transmits force, and reduces the sway of the support frame 3 during use and concrete pouring. The anti-detachment block 8 can also be designed as a spherical structure to improve the structural reliability, which will not be elaborated here.

[0063] In this embodiment, the support base 1 has a feed hole 9 along its height direction, which connects to the adjustment chamber. The feed holes 9 extend along the entire length of the support base 1, that is, along the length of the cylinder. There are multiple feed holes 9, evenly distributed around the cylinder in this design, making the projection of the cylinder approximate the shape of a comb. The feed holes 9 allow concrete to enter the adjustment chamber through the feed holes 9 during the pouring of the post-cast concrete protective layer. After the concrete has set, the entire device is completely embedded in the concrete, with no moving points, further enhancing the overall structural strength. Especially after the adjustment chamber is filled with concrete, the overall structure is more compactly embedded in the functional holes in the insulation layer 003, preventing local defects in the concrete protective layer, resulting in excellent overall consistency and construction quality.

[0064] In this embodiment, the support frame 3 includes a main frame 5, which is a grid-shaped double-layer steel mesh. Several functional ribs 6 connect and support the nodes of the grid-shaped double-layer steel mesh along the vertical direction. The main frame 5 is located in the middle of the length direction of the functional ribs 6, forming a support frame 3 with a spatial support structure.

[0065] In use, the functional rib 6 extends upward to the preset height of the functional hole, and the functional rib 6 extends downward into the adjustment cavity and is limited; there are at least two functional ribs 6, so that the position of the anchor bar in the metal roof support system can be marked by the position of the functional rib 6.

[0066] In this embodiment, each support frame 3 includes four functional ribs 6. The area enclosed by the four functional ribs 6 can be used to install anchor bars. It should be understood that before implanting the anchor bars, the exposed part of the functional ribs 6 protruding from the concrete protective layer 004 should be cut off, leaving only the reinforcing bar points. The metal roof support system 005 also includes supports set on the anchor bars, keel purlins built on the supports, and roof panels supported by the keel purlins, etc., which will not be described in detail here.

[0067] This solution also discloses a construction method based on a sloping curved roof structure, including the following construction steps:

[0068] S1. Construction of the foundation layer 001 provides a reliable supporting foundation for subsequent steps and improves the overall construction quality;

[0069] S1a. Laying the bottom formwork 101 of the foundation layer 001; In this scheme, the bottom formwork 101 is a wooden formwork, which is equivalent to the curvature of the sloping roof. The foundation layer 001 is removed and reused after curing.

[0070] S1b. A concrete interception structure is provided on the bottom formwork 101 of the base layer 001, the concrete interception structure being used to enhance the retention capacity of concrete and control the concrete slump.

[0071] S1c. Concrete segments of the foundation layer 001 between adjacent concrete interception structures are poured sequentially from bottom to top to complete the construction of foundation layer 001. After each concrete segment of foundation layer 001 is poured, the concrete in this segment is vibrated and then manually smoothed after each segment is vibrated to ensure that the surface flatness of the segment meets the preset index and optimizes the quality of the base layer.

[0072] This solution, by setting up a concrete interception structure and pouring it in batches from bottom to top, can control the concrete slump of long, sloping roofs. Furthermore, the concrete interception structure connects the top and bottom reinforcing meshes 105 and 106 pre-embedded within the foundation layer 001, effectively enhancing the support strength of the entire foundation layer 001. In particular, the overall structural design constitutes a multi-dimensional integrated construction method, and the synergistic force-bearing system of the entire structure effectively improves the density of the roof concrete structure, enhances protective performance, and reduces the risk of leakage. The composite anti-slip layer composed of the interception mesh 102, the top reinforcing mesh 105, and the bottom reinforcing mesh 106 makes it easier to control the flatness of the concrete, resulting in superior construction quality for the sloping roof. Moreover, the single-formwork design reduces erection time, increases formwork turnover rate, and lowers overall construction costs, making it more economical. By improving the structural strength and quality of the foundation layer 001, the risk of bottom cracking can be reduced, improving the reliability of seepage prevention.

[0073] S2. After the base layer 001 has cured, remove the bottom formwork 101 and construct the waterproof layer 002 on the base layer 001.

[0074] S3. Apply insulation layer 003 on top of waterproof layer 002.

[0075] S3a. A support structure is installed within the functional hole. During construction, the support structure is pre-embedded in the concrete protective layer 004 on top of the insulation layer 003. This enhances the anti-slip capability of the insulation layer 003 and improves the reliability of its connection with the concrete protective layer 004. Furthermore, the support structure also functions as a supporting component, adjusting its height to effectively support the reinforcing mesh in the concrete protective layer 004 for insulation layers of different depths, specifying the height and angle of the reinforcing mesh in the concrete protective layer 004. The support structure has protruding indicators on the concrete protective layer 004, which can be used to directly determine where the anchor bolts 501 of the metal roof support system 005 can be installed. This will not damage the bottom insulation layer 003 or the waterproof layer 002, reducing the risk of leakage. Furthermore, the metal roof support system 005 has better anchoring stability and higher pull-out bearing capacity. In addition, the high installation accuracy of the supports in the metal roof system can effectively prevent misalignment of the post-installed anchor bolts 501 during construction. It is an integrated multi-functional structure that can save construction costs and is more economical.

[0076] S3b. Adjust the reference plane so that the functional reinforcement 6 of the main frame 5, supported by the reference plane, extends beyond the preset height of the insulation layer 003. This step corresponds to adjusting the height of the main frame 5 to determine the local location, angle, and height of the steel mesh in the subsequent concrete protective layer 004 laid on the main frame 5. Simultaneously, it ensures that the functional reinforcement 6 extends beyond the insulation layer 003 and the subsequent concrete protective layer 004, serving as an indicator. It should be understood that before this step, the support structure is assembled. During use, only the movable block at the bottom of the corresponding area of ​​the main frame 5 needs to be rotated to adjust the height accordingly. Simultaneously, the angle of the main frame 5 is adjusted adaptively, making construction convenient and highly adaptable, resulting in higher construction quality for the subsequent concrete protective layer 004.

[0077] S4. Concrete protective layer 004 is constructed on insulation layer 003, and the support structure is pre-embedded; in this state, insulation layer 003, support structure and concrete protective layer 004 are connected to form a whole, improving the overall consistency, and the support structure can also be used as a stirrup, resulting in better structural strength.

[0078] In this embodiment, the thickness of the concrete protective layer 004 does not exceed the preset height of the functional reinforcement 6 extending upward from the functional hole, so that after the concrete protective layer 004 is constructed, the functional reinforcement 6 is exposed outside the concrete protective layer 004, serving as an identifier for the anchor bars in the subsequent metal roof support system 005, playing a positioning function, ensuring the precise alignment of the anchor bolt 501, avoiding anchorage failure, ensuring the flatness and load transfer reliability of the metal roof keel support system, and at the same time avoiding damage to the waterproof layer 002, thus improving the construction quality.

[0079] S5. Construct a metal roof support system 005 on the concrete protective layer 004; the metal roof support system 005 includes anchor bolts 501, which are inserted into the concrete protective layer 004 between two functional reinforcing bars 6.

[0080] In this embodiment, the use of this support structure and construction method can effectively ensure the waterproof reliability of the sloping arch roof, actively avoid damage to the waterproof layer 002 by the post-installed anchor bolt 501, and greatly reduce the risk of leakage. The support structure with adjustable angle and height has stronger adaptability and meets the usage requirements. After pouring, it is completely embedded in the entire concrete structure, with no defective points, resulting in better construction quality. At the same time, the structure of the pre-reserved functional holes on the insulation board of this solution can be stacked with the thickness of the concrete protective layer 004 to meet the anchoring depth of the anchor bolt 501 and effectively meet the pull-out bearing capacity of the roof support. The display mark at this location provides a precise installation position for the anchor bolt 501, with high support installation accuracy, effectively preventing misalignment of the post-installed anchor bolt 501 during construction. In particular, this solution can effectively control construction costs downward. The support structure also functions as an elevation control, stirrup reinforcement, and structural reinforcement component, saving the use of formwork, simplifying construction steps, saving labor input, and making it more economical.
