Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a casting load-bearing structure for a curved concrete roof. Background Technology

[0002] In some large public buildings, to express the architecture and its inherent meaning, a beautiful shape and a uniquely structured landmark are required. Often, the roof is made curved. Some buildings, for aesthetic purposes, feature hyperboloid roofs. Hyperboloid roofs are typically supported by single-curved steel beams, with corrugated profiled steel sheets laid on top of these single-curved beams. The crests and troughs of the profiled steel sheets adapt to the curved surface of the steel beams. The profiled steel sheets are tilted to support the other side of the curved surface, creating a hyperboloid shape within the space. The profiled steel sheets serve as the base formwork for the upper concrete, and concrete is then laid on top of the profiled steel sheets, forming the hyperboloid shape.

[0003] The load on the corrugated steel sheet is transferred through the following path: both the permanent and dynamic loads of the roof are transferred to the corrugated steel sheet. The corrugated steel sheet then transfers the roof load to the secondary steel beams, which in turn transfer it to the main beams, and finally to the steel columns, thereby achieving the purpose of providing stable support for the building.

[0004] The roof of this sloping building needs to be curved, which can only be achieved by pouring concrete using formwork. The roof top is then shaped manually from the poured concrete into the desired form.

[0005] When pouring this type of concrete, because the roof's base membrane is curved, the concrete will flow downwards due to gravity, especially finer concrete, which has even greater fluidity. After a period of time, the aggregates such as sand and gravel remain relatively still, while the water and fine concrete flow downwards, making it difficult to achieve the intended thickness. This causes the concrete at higher elevations to lose some support, potentially leading to partial or complete collapse and the concrete flowing downwards. Consequently, the poured concrete cannot reach the preset thickness, and at curved surfaces with significant height differences, the concrete may not even be poured and formed properly.

[0006] This type of building structure also presents technical challenges in terms of support: 1. Because the profiled steel sheet is inclined in the longitudinal direction and curved in the transverse direction, the contact area between the profiled steel sheet and the top surface of the curved beam is small. In particular, since the profiled steel sheet and the curved beam are supported at an incline, the curved beam and the profiled steel sheet form a line contact, which creates a large triangular gap at the support point between the curved beam and the profiled steel sheet. The profiled steel sheet cannot completely transfer the roof load to the steel beam and can only rely on the strength of the profiled steel sheet itself to bear the load, resulting in insufficient load-bearing capacity.

[0007] 2. When connecting profiled steel sheets to steel beams, shear studs are used to anchor and weld the sheets to the beams. However, because the profiled steel sheets are inclined and rest on the curved steel beams, the shear studs need to penetrate the sheets before welding to the beams. At this point, the weld points are exposed in the gap between the profiled steel sheets and the beams, making them and the studs susceptible to corrosion in humid environments. This affects the overall connection strength of the profiled steel sheets. Since the connection area between the sheets and beams is already small, if the studs and welds rust or crack, there is a risk of separation between the sheets and beams, creating a safety hazard.

[0008] These conditions can all lead to insufficient structural strength and high fluidity of the top concrete, further resulting in uneven load distribution on the roof. Lower sections of the profiled steel sheet bear excessive loads, while higher sections bear almost no load, exacerbating the load-bearing capacity issues and potentially causing the building structure to bend or collapse. These factors, in turn, affect the roof structure, preventing it from forming a complete curved surface and achieving the desired shape.

[0009] Based on this, this utility model designs a casting load-bearing structure for a curved concrete roof to solve the above problems. Utility Model Content

[0010] The purpose of this invention is to provide a concrete curved roof casting load-bearing structure. This device adds a thickness adjuster and a height-limiting net, which can limit and mark the thickness of the poured concrete, form an anti-cracking layer for the concrete, and improve the flatness of the top of the poured concrete, preventing unevenness. It also uses a flow-stopping net to intercept fine concrete flowing downwards, ensuring that the concrete solidifies and forms according to the designed thickness and shape after pouring. This results in a more uniform distribution of concrete on top of the profiled steel sheet, leading to more even stress distribution. The anchor plate is tightly fitted to the top surface of the curved beam, forming a larger connection area and increasing the connection strength between the two. Furthermore, the studs and welds to the curved beam are located inside the concrete above the profiled steel sheet, effectively preventing the studs from contacting air, reducing the chance of corrosion, and increasing service life. The profiled steel sheet and the curved beam are welded together using the same stud to form an integral structure, increasing the overall integrity of the structure and improving structural safety.

[0032] The fixing plate is locked to the profiled steel plate by rivets.

[0033] Furthermore, the height restriction net is made of steel wire mesh;

[0034] The number of mesh openings in the height restriction net shall not be less than 1000 per square meter;

[0035] The diameter of the water-stopping clamp and the top locking plate is larger than the aperture of any mesh of the height-limiting net.

[0036] Furthermore, the flow-stopping mesh is a perforated mesh plate, and the number of mesh holes per square meter is not less than 1200;

[0037] The flow-stopping net is locked to the height-limiting bar by a buckle; a flow-stopping net is vertically installed between any two of the height-limiting bars and can be detached.

[0046] The beneficial effects of this utility model are: 1. This device adds a thickness adjuster, which can lay and clamp the height limit net, so that the height limit net can be laid on the profiled steel plate. The thickness of the concrete pouring can be referenced through the height limit net, and the top layer of the concrete can be intercepted and restricted, so that the top of the concrete cannot flow to the lower place, avoiding the freshly poured concrete from becoming fluid, and making the concrete form according to the set thickness.

[0047] 2. This device also includes a thickness adjuster, which clamps the height-limiting net with a water-stop clamp and a top locking plate. The height of the water-stop clamp and the top locking plate can be adjusted on the height-limiting bar, so that this device can easily limit the thickness of concrete and flexibly adjust the pouring thickness of concrete according to the actual construction and design scheme. It is easy to use, and the height-limiting bar is cast into the concrete as a whole, forming a vertical skeleton, which can also play a role in reinforcing the entire concrete pouring structure.

[0048] 3. This device also includes a flow-stopping net, which can directly intercept and lock the concrete at low points, ensuring that the concrete structure does not overflow in large quantities, and ensuring that the sides of the poured concrete can be completely formed, so that the concrete structure can solidify according to the set shape.

[0049] 4. This utility model cuts profiled steel sheets into anchor plates, which are fully fitted to the curved beams, resulting in a large contact area and a more robust connection. This allows the profiled steel sheets to transfer a larger load to the curved beams, which in turn support the profiled steel sheets, thus transferring the load to the building columns. This meets the structural bearing capacity requirements, improves the overall structural safety, and prevents overloading of the profiled steel sheets. The device also includes side and top sealing plates, connecting the entire anchor plate into a unified structure. The anchor plate, profiled steel sheets, and curved beams are all firmly welded together with studs, and a single weld point can integrate all three components, achieving a strong connection and shear resistance. The flat laying of the anchor plate facilitates stud installation, making construction easier. Furthermore, the anchor plate is fully fitted to the curved beams, and the studs and weld points are all located above the profiled steel sheets. After construction, the studs and weld points are embedded in the concrete, preventing them from being exposed to the air and reducing the risk of corrosion. This effectively improves the structural connection life and strength.

[0050] 5. This device also includes side and top panels. These flat rubber sheets are lightweight and easy to install. During the cutting process, the side and top panels can be attached to the side and top sealing panels, effectively sealing them and preventing them from contacting air. During construction, no scaffolding is required; simply attach them to the inside of the designed welding path before welding. No further construction is needed. Once the side and top sealing panels are welded to the profiled steel sheet, the construction is complete. The sealing effect is excellent, and the entire connection structure is doubly sealed, effectively reducing the occurrence of corrosion at the structural connection points.

Detailed Implementation

[0067] Please see Figures 1 to 13 As shown, this utility model provides a cast-in-place load-bearing structure for a curved concrete roof. To better understand the above technical solution, the following will provide a detailed description of the above technical solution in conjunction with the accompanying drawings and specific embodiments.

[0068] In a specific embodiment of the technical solution of this utility model:

[0069] The building structure includes: profiled steel sheet 3, curved beam 31, and column 32. Column 32 is a pile foundation column, and curved beam 31 is a bent I-beam. Curved beam 31 is fixedly welded to the top of column 32. Multiple connectors are arranged in a rectangular array on profiled steel sheet 3. The trough surface of profiled steel sheet 3 is fixedly welded to the top of curved beam 31 through connectors. Profiled steel sheet 3 is inclined and curved, and the inclination direction is along the longitudinal line of the crest and trough of profiled steel sheet 3. That is, the same crest or the same trough is higher at one end and lower at the other end, which makes it easy for the curved surface of profiled steel sheet 3 to fit with curved beam 31.

[0070] The connectors include: anchor plate 4, studs 43, side panels 5, and top panel 51;

[0071] Anchor plate 4 is a flat plate. The lower edge of anchor plate 4 is integrally connected to profiled steel plate 3. The profiled steel plate 3 is open at the support frame of curved beam 31. The bottom of anchor plate 4 is tightly attached to the top of curved beam 31. Anchor plate 4 is a portion of profiled steel plate 3 cut at the recess. Anchor plate 4 is not completely cut off from profiled steel plate 3. It is cut off on the left and right sides, and the top side near the high position is cut off. The lower side remains connected. A side sealing plate 41 is set on each of the left and right sides of anchor plate 4. Anchor plate 4 and side sealing plate 41 are connected as an integral structure.

[0072] A top sealing plate 42 is also provided on the upper side of the anchor plate 4. The anchor plate 4, two side sealing plates 41 and one top sealing plate 42 form a closed groove for the top opening. The two side sealing plates 41 are respectively sealed and fitted to the left and right sides of the opening of the profiled steel plate 3. The top sealing plate 42 is covered and fitted to the upper side of the opening of the profiled steel plate 3. The opening of the profiled steel plate 3 is closed and isolated by the anchor plate 4, the side sealing plates 41 and the top sealing plate 42.

[0073] Two side sealing plates 41 and one top sealing plate 42 are welded to the top of the profiled steel sheet 3;

[0074] The gap between the anchor plate 4 and the profiled steel sheet 3 is sealed by welding the side sealing plate 41 and the top sealing plate 42. This ensures a seamless connection between the anchor plate 4 and the profiled steel sheet 3, ensuring complete isolation and forming both the interior and exterior sides of the building.

[0075] Multiple studs 43 are provided on the anchor plate 4. The anchor plate 4 and the curved beam 31 are welded together to form an integral load-bearing structure through the studs 43. The studs 43 are located in the closed groove at the top of the anchor plate 4 and are shear studs.

[0076] The length of the stud 43 is less than the height difference between the crest surface and the trough surface of the profiled steel sheet 3. The profiled steel sheet 3 is a crest surface that is raised, and the adjacent one is a trough surface that is recessed downward. The crest surface and the trough surface are connected in parallel to form a complete profiled steel sheet 3, ensuring that the top of the stud 43 does not protrude upward above the profiled steel sheet 3, thus avoiding the situation where the stud 43 is exposed after the concrete is poured.

[0077] The stud 43 penetrates the anchor plate 4 and is welded to the curved beam 31; the bottom surface of the anchor plate 4 is welded to the top plane of the flange of the curved beam 31.

[0078] The side panel 5 is a right-angled triangular flat plate, and the upper panel 51 is a square flat plate. The upper panel 51 is connected and fixed to one right-angled side of the side panel 5. The two side panels 5 and the upper panel 51 form a U-shaped groove structure, and the two side panels 5 are symmetrically arranged on the left and right sides of the upper panel 51. The bottom of the upper panel 51 is also provided with a support plate 52. The upper panel 51 and the support plate 52 form an L-shaped plate.

[0079] The side panels 5 on both sides are attached to the inner side of the side sealing plate 41, and the upper panel 51 and the exposed part of the top sealing plate 42 on the inner side of the building are tightly attached; the support plate 52 is tightly attached to the flange at the top of the curved beam 31.

[0080] The side panels 5, the upper panel 51, and the support plate 52 are all fireproof rubber sheets. The side sealing plate 41 and the top sealing plate 42 form a barrier. The side panels 5, the upper panel 51, and the support plate 52 are sealed and attached to the inner side of the closed groove formed by the side sealing plate 41 and the top sealing plate 42 with adhesive. This ensures that the inner parts of the side sealing plate 41 and the top sealing plate 42 exposed to the air are covered and sealed by the side panels 5 and the upper panel 51, preventing the side sealing plate 41 and the top sealing plate 42 from contacting the air. The inner side of the anchor plate 4 is tightly fitted and sealed with the curved beam 3, and it does not come into contact with the air after welding.

[0081] The thickness limiting device includes: a thickness adjuster 1, a height limiting net 2, and a flow-stopping net 21;

[0082] The profiled steel sheet 3 is a flexible corrugated sheet; the profiled steel sheet 3 is inclined along the groove axis of the corrugation; multiple thickness adjusters 1 are fixed on the crest surface of the profiled steel sheet 3; the profiled steel sheet 3 is connected between the thickness limiting device and the building structure, and plays the role of transferring load, transferring the concrete structural load on the top of the profiled steel sheet 3 to the curved beam 31 and the column 32, thereby achieving the load-bearing function;

[0083] Both height restriction netting 2 and flow-stopping netting 21 are flexible, flat mesh panels; height restriction netting 2 is made of steel wire mesh; the number of mesh openings in height restriction netting 2 is no less than 1000 per square meter. Flow-stopping netting 21 is a perforated mesh panel; the number of mesh openings in flow-stopping netting 21 is no less than 1200 per square meter.

[0084] The diameters of the water-stopping clamp 12 and the top locking plate 11 are larger than the aperture of any mesh of the height-limiting net 2;

[0085] The diameter of the height restriction pole 13 is also larger than the aperture of the height restriction net 2. However, in order to install it, the wire mesh needs to be cut or penetrated for installation and insertion. This also allows for a tighter wrapping, and the addition of the water-stop clamp 12 can seal the penetration or cut points to prevent excessive overflow.

[0086] The height restriction net 2 is detachably locked to the top of the thickness adjuster 1, and the height restriction net 2 is laid out directly above the profiled steel sheet 3 without contacting the thickness adjuster 1;

[0087] The flow-stopping mesh 21 is vertically locked to the thickness adjuster 1 via a latch;

[0088] The thickness adjuster 1 includes a top locking plate 11, a water-stop clamping ring 12, a height limiting rod 13, a water-stop plug 14, and a fixing plate 15; the top locking plate 11 and the fixing plate 15 are both flat plates, and the fixing plate 15 is attached to and fixed on the profiled steel sheet 3, and fixed on the raised corrugated plate of the profiled steel sheet 3; the top locking plate 11, the water-stop clamping ring 12, and the fixing plate 15 are all circular flat plates;

[0089] The water-stop plug 14 is a frustum-shaped rubber plug that is larger at the top and smaller at the bottom. The water-stop plug 14 has a threaded hole inside, which runs vertically through the water-stop plug 14. The diameter of the top frustum plane of the water-stop plug 14 is not less than 3cm.

[0090] The water-stop plug 14 is clamped at the bottom of the height restriction net 2. The lower end of the water-stop plug 14 is attached to the top of the top locking plate 11, which limits the water-stop plug 14. Through the structure of the sponge and the closed structure at the top of the water-stop plug 14, it can not only clamp the height restriction net 2, but also prevent the top of the height restriction bar 13 from protruding outside through the top locking plate 11, thus preventing personnel from accidentally falling and being stabbed during construction. Therefore, the water-stop plug 14 can not only stop water, but also provide protection.

[0091] The axes of the top locking plate 11, the water-stop clamping ring 12, the height limiting rod 13, and the fixing plate 15 are aligned to ensure greater accuracy during overall installation. Positioning is based on the axis of the height limiting rod 13, but deviations are permissible as the device does not require high precision. The locking position of the fixing plate 15 on the profiled steel sheet 3 can be flexibly adjusted according to actual construction needs. During construction, the actual height limit surface requirements should be considered.

[0092] The fixing plate 15 is locked to the profiled steel plate 3 by rivets or by welding. As long as the fixing plate 15 is fixed to the profiled steel plate 3, the fixing plate 15 can be used to position the height limit bar 13. The height limit bar 13 not only plays the role of positioning and adjustment, but also forms a reinforcing bar structure after the concrete is poured and formed, which can act as the internal steel reinforcement of the concrete and increase the overall load-bearing capacity of the concrete.

[0093] The height limit bar 13 is a threaded bar, and the height limit bar 13 is vertically fixed to the top of the fixing plate 15, that is, the fixing plate 15 is set at the lower end of the height limit bar 13, and the height limit bar 13 and the fixing plate 15 are welded to form an integral structure.

[0094] Both the top locking plate 11 and the water-stop clamping ring 12 are flat plates, and both the top locking plate 11 and the water-stop clamping ring 12 are installed on the height limit bar 13 by means of threads that can be raised and lowered.

[0095] The water-stop plug 14 is a rubber plug, and the water-stop plug 14 is installed on the height limit bar 13 by thread;

[0096] The top locking plate 11, the water-stop plug 14, the water-stop clamping ring 12, and the fixing plate 15 are arranged on the height limit bar 13 from top to bottom;

[0097] The height restriction net 2 is installed on the height restriction pole 13, and the height restriction net 2 is stably clamped between the water-stop clamping ring 12 and the top locking plate 11.

[0098] The flow-stopping net 21 is locked to the height-limiting bar 13 by a buckle. A flow-stopping net 21 is vertically installed between any two height-limiting bars 13 and can be detached. The buckle is a ring spring buckle. This structure allows for easy installation and removal of the flow-stopping net 21 from the height-limiting bar 13. Simply place the flow-stopping net 21 vertically and then fasten the mesh of the flow-stopping net 21 to the height-limiting bar 13 at different heights. If a tighter locking relationship is required, the flow-stopping net 21 can be tied to the height-limiting bar 13 with wire, or even welded directly to the height-limiting bar 13, ensuring that the flow-stopping net 21 is set vertically and can effectively stop the flow of concrete.

[0099] It should be noted that:

[0100] 1. The flow of concrete does not start from the bottom, but rather the top layer of concrete flows downwards, exposing the concrete that was previously inside, and then flows downwards again, causing the concrete to form a mudslide-like state that flows continuously from high to low, making it difficult for the concrete to solidify and form according to the set thickness. This device can cover the top plane of the poured concrete with the height restriction net 2, ensuring that the top of the freshly poured concrete is restricted by the height restriction net 2, thereby ensuring that the top of the concrete does not flow downwards, but is restricted and kept in a fixed position to solidify.

[0101] 2. When concrete is poured on a sloping surface, the concrete at the lowest vertical section is prone to leakage and flow, making it impossible to form. Generally, formwork is needed for batch pouring. However, pouring section by section, with wooden formwork around the edges, will create gaps between adjacent sections after solidification. Without formwork, it will not form properly. Batch pouring at intervals, due to the difference in the pouring sequence, can easily lead to unevenness and cold joints. Intermittent pouring is a suitable method... Figure 2 As shown, these are all problems encountered in building construction. This device uses a flow-stopping net 21, which can be bound to the height-limiting bar 13 to restrict its position, allowing all the concrete to be poured completely at the same time. Figure 3 As shown, the concrete can be poured in one go, and can also be divided into sections during the same pour, thereby limiting the flowability of the concrete. The one-time pour allows for smoothing and vibration, ensuring a compact concrete structure. It also avoids unevenness caused by sequential pouring and prevents cold joints. Furthermore, the pouring stop net 21 can be removed and reused when the concrete is almost set, or it can be left in the concrete to form a reinforcing structure, increasing the structural strength of the concrete. It is convenient and flexible to use, and the one-time molding structure has high strength and strong overall integrity.

[0102] 4. The corrugated steel sheet 3 has a wavy, uneven surface, allowing it to be bent along the direction of the folds, thus forming a shape similar to the designed curved surface for support and forming the bottom formwork for concrete pouring. Only by bending the corrugated steel sheet 3 in this way can this architectural curved surface effect be achieved. The non-folded direction of the corrugated steel sheet 3 cannot be bent and can only be supported in a straight position. This results in an angle between the top of the curved beam 31 and the corrugated steel sheet 3. In the existing structure, the corrugated steel sheet 3 is placed flat and inclined on the curved beam 3. In the previous method, the contact area between the two was very small, with support only provided at the corner of the curved beam 31. The load could not be effectively transferred, resulting in a wedge-shaped gap with a triangular cross-section between the profiled steel sheet 3 and the building. This led to insufficient support for the profiled steel sheet 3, and the structure relied entirely on welding with studs 43, resulting in low structural strength. This device, however, is completely different. It cuts the connection points of the profiled steel sheet 3 along the left, right, and top directions to form anchor plates 4. These anchor plates 4 are then pressed down to form a flat plate that fits against the curved beam 31. Figure 10 As shown, the studs 43 on the top of the anchor plate 4 pass through the profiled steel plate 3 and are welded firmly to the curved beam 31, forming a connecting component that integrates the three parts into one, thus forming an overall structure.

[0103] 5. In this wedge-shaped gap, the space is insufficient and the height is too large, making it too difficult to build the formwork. As a result, concrete cannot be poured for support. In the end, a pad can only be inserted at the bottom of the profiled steel plate 3. The space is too narrow and the top space is too low, making it impossible to wear a welding mask and weld. This device does not require operation inside the profiled steel plate 3, i.e., at the bottom. Instead, it can directly use adhesive to attach the side panel 5 and the top panel 51. The operation is simple, the construction is convenient, and the construction difficulty is low. Attaching the side panel 5 and the top panel 51 is only for further rust prevention and sealing effect. The effect is good and effectively seals and protects the side sealing plate 41 and the top sealing plate 42.

[0104] Moreover, in the existing structure, the lower end of the stud 43 penetrates the profiled steel plate 3 and is exposed in the wedge-shaped gap, making it prone to corrosion. However, in this device, the stud 43 is welded inside the anchor plate 4 and simultaneously welded together with the top of the curved beam 31 to form a whole. The stud 43 body is above the profiled steel plate 3 and is finally poured and embedded in concrete, preventing contact with air. This makes the stud 43 of this device less prone to corrosion, and the structural strength and durability are better.

[0105] When constructing the building structure, this utility model first installs the basic support components such as the curved beam 31 and the column 32. Then, the profiled steel sheet 3 is taken out. The length of the profiled steel sheet 3 needs to meet the design requirements. Alternatively, a smaller profiled steel sheet 3 can be selected according to the actual hoisting requirements. Multiple profiled steel sheets 3 can be spliced ​​together to form a complete roof support floor slab. The connection and support points between the profiled steel sheet 3 and the curved beam 31 are cut. The left and right sides and the inclined upper side of the components that need to be supported and connected are cut open. The lower side of the anchor plate 4 is connected to the profiled steel sheet 3 to form an overall structure. Then, it is pressed down and bent to form the anchor plate 4. The bottom of the anchor plate 4 is attached to the flange plate at the top of the curved beam 31.

[0106] Then remove the stud 43, and weld the stud 43, anchor plate 4 and profiled steel plate 3 into a whole, ensuring that the weld penetrates the profiled steel plate 3 and welds to the curved beam 31, ensuring that there is no gap or void at the connection between the profiled steel plate 3 and the curved beam 31, and that the entire anchor plate 4 is firmly welded to the profiled steel plate 3.

[0107] Then, take out two side sealing plates 41 and two side enclosure plates 5. Press down the anchor plate 4, and its left and right sides form a broken triangular hole with the profiled steel plate 3. Make a layout measurement on both sides of the anchor plate 4 to determine the size of the hole. Then cut a larger area of ​​side sealing plate 41 to ensure that the side sealing plate 41 covers the gap between the left and right sides of the anchor plate 4 and the profiled steel plate 3. Glue the side enclosure plate 5 on the curved beam 31 in the building interior space of the hole, and glue the side enclosure plate 5 to the building interior side of the side sealing plate 41 at the same time to ensure that the glue is firm. Then place the side with the glued side enclosure plate 5 facing the interior side. Then bend the side sealing plate 1 and glue it to the profiled steel plate 3 to ensure that the hole between the profiled steel plate 3 and the anchor plate 4 is completely covered. Then weld the side enclosure plate 5 to the profiled steel plate 3 and the anchor plate 4 to form a sealed and complete structure.

[0108] Similarly, the side sealing plates 41 on both the left and right sides are welded to the side panels 5 in the same way. At the same time, the bottom and top edges of the side panels 5 need to be tightly and securely fitted to the profiled steel sheet 3 and the curved beam 31. The installation method of the top sealing plate 42 is the same as that of the side sealing plates 41. The top sealing plate 42 is also pushed into the interior side after the upper panel 51 is pasted on the interior side. Finally, the top sealing plate 42 is welded and sealed to the profiled steel sheet 3 and the anchor plate 4. This completely welds the opening between the anchor plate 4 and the profiled steel sheet 3, so that the side sealing plates 41, top sealing plates 42 and anchor plates 4 form a completely closed downward groove.

[0109] Later, a longer spray painting device can be used indoors to spray a release liner or release paint onto the interior side of the side panel 5. Finally, concrete needs to be poured on top of the profiled steel sheet 3, and the concrete should be shaped to form a curved roof surface.

[0110] The upper side of this device refers to the higher side of the inclined profiled steel sheet 3, and the lower side refers to the lower side of the inclined sheet. The inside and outside of this device refer to the interior of the building and the exterior of the roof. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the attached drawings. It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0111] In this invention, during concrete pouring, the area to be poured is designed, and a fixing plate 15 is installed. A height-limiting rod 13 is welded to the fixing plate 15. The fixing plate 15 is then riveted or welded to the profiled steel sheet 3. A water-stopping clamp 12 is first installed on the height-limiting rod 13. The height position of the water-stopping clamp 12 on the height-limiting rod 13 is adjusted. This position is the coverage height of the height-limiting net 3, which is the final curved shape of the building's roof formed by the concrete. Therefore, the height position of the water-stopping clamp 12 needs to be measured and positioned to ensure that the position conforms to the designed roof curvature.

[0112] Then, cover the height restriction net 2 on the height restriction bar 13 so that the height restriction bar 13 penetrates the height restriction net 2, and the height restriction net 2 needs to be attached to the top of the already installed and stable water-stop clamp 12.

[0113] Install the water-stop plug 14 and the top locking plate 11. The water-stop plug 14 is installed below the height restriction net. Press the top locking plate 11 knob onto the top of the height restriction net 2, so that the height restriction net 2 is clamped between the top locking plate 11 and the water-stop clamping ring 12. Ensure that the upper end of the water-stop plug 14 is tightly against the top of the top locking plate 11. You can add a rubber gasket or directly cut the height restriction rod 13 to make its length suitable. As long as you ensure that the top of the top locking plate 11 is tightly against the water-stop plug 14, the gap can be sealed.

[0114] Then, a flow-stopping net 21 is vertically stretched between the two lower height-limiting poles 13. The flow-stopping net 21 can be a mesh or steel wire, but it needs to have higher load-bearing strength and be thinner. One side of the flow-stopping net 21 is stretched and tied to the height-limiting pole 13 using buckles or wire. Then, the other side of the flow-stopping net 21 is stretched and tied to the adjacent height-limiting pole 13, ensuring that the flow-stopping net 21 intercepts the concrete in the direction of downward flow, thereby trapping the concrete and allowing it to solidify and form in a fixed position.

[0115] This device achieves the purpose of interception and limitation on the top and bottom surfaces of the concrete. Similarly, if interception is also required on the left and right sides of the concrete block, it is only necessary to install flow-stopping nets 21 on the two height-limiting bars 13 on the left and right sides.

[0116] This device is an integral structure that supports the profiled steel sheet 3 through connectors, thereby providing stable support for the concrete poured on the roof. However, this operation is not required for steel structure roofs, nor is it necessary for flat roofs. This device also uses a thickness limiting device to uniformly limit the load on the roof, preventing concrete from overflowing after pouring and ensuring that the load on the concrete on top of the profiled steel sheet 3 is uniform. This also ensures that the concrete on the roof can form a smooth and flat hyperboloid roof as required by the design.

Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
