Description

Technical Field

[0001] This invention belongs to the field of building formwork technology, and in particular relates to a facade design formwork for cantilever structures and its construction method. Background Technology

[0002] Modern architecture often features cantilevered structures with unique facade designs, such as sky gardens. Current technology typically uses ordinary wooden or aluminum formwork as the standard template for these structures, which presents several technical problems: First, the process is cumbersome, requiring the construction of drip lines, beak-like structures, or other decorative elements after demolding, consuming significant manpower, resources, and time. Second, the verticality of the facade template is difficult to adjust precisely, easily leading to uneven structural edges and affecting subsequent curtain wall or decoration work. Third, the junction between the facade and base templates is difficult to fit tightly, easily causing grout leakage and resulting in defects such as "rotten roots" and honeycombing, affecting the structure's appearance and durability. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a facade design template for cantilever structures and its construction method, which can simultaneously construct the decorative structure of the cantilevered end facade during the pouring of the cantilever structure, simplifying the construction process and improving construction quality.

[0004] The technical solution adopted in this invention is: a facade design template for cantilever structures, comprising a side formwork frame and adjustment components. The side formwork frame includes a main frame and an extension section. The extension section is vertically connected to the bottom end of the main frame, and its end away from the main frame has an overlapping section. The main frame includes an inner wall and an outer wall arranged opposite to each other. The inner wall has a concave-convex structure. Multiple sets of adjustment components are movably arranged on the outer wall.

[0005] Furthermore, the side mold frame is made of aluminum alloy profile in one piece.

[0006] Furthermore, the overlapping section has a positioning groove on the side facing the inner wall.

[0007] Furthermore, a sealing strip is provided in the positioning groove, and the sealing strip is arranged along the length direction of the side mold frame.

[0008] Furthermore, the extension section also includes a straight section, which is connected to the main frame via the straight section, and the straight section is provided with a drip strip.

[0009] Furthermore, the main frame is also provided with cavities, which are divided into multiple independent spaces by reinforcing ribs.

[0010] Furthermore, the adjustment component is disposed at one end of the outer wall near or away from the extension section.

[0011] Furthermore, the adjustment components are arranged at equal intervals along the length direction of the side mold frame.

[0012] Furthermore, the adjustment assembly includes a fixing nut and an adjusting bolt; the fixing nut is embedded in the outer wall; the adjusting bolt includes a head and a rod, the rod is threaded to the fixing nut, and the head is connected to one end of the rod located on the outside of the main frame.

[0013] The method of using the facade design template for cantilever structures as described above is characterized by including the following steps:

[0014] Erect the supporting structure;

[0015] Install the main template and side frame;

[0016] Adjust the verticality of the main frame.

[0017] The advantages and positive effects of this invention are:

[0018] (1) By setting a side formwork frame and setting a concave-convex structure on the inner wall of the main frame, the decorative structure of the suspended end facade can be constructed simultaneously when the cantilever structure is poured. Compared with the implementation method of constructing the cantilever structure first, removing the formwork and then constructing the decorative structure, the construction process is simplified, and manpower, material resources and construction time are effectively saved. This is conducive to reducing construction costs and shortening the construction period. In addition, the decorative structure is integrally formed with the main structure, which has better integrity and can also effectively avoid the risk of falling off.

[0019] (2) By setting an extension section, an installation groove is set in the extension section to overlap with the main template, and a sealing element is set in the installation groove, which can effectively prevent grout leakage during concrete pouring, thereby improving the construction quality and durability of the cantilever structure.

[0020] (3) By setting up adjustment components, the verticality of the main frame can be precisely adjusted to ensure that the geometric lines of the suspended end facade are straight, which further improves the construction quality.

[0021] (4) The side mold frame is strong, lightweight and durable, and can be mass-produced according to uniform specifications to reduce processing costs. Attached Figure Description

[0026] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 As shown in the figure, this embodiment of the invention proposes a facade design template for cantilever structures, including a side formwork frame and adjustment components. The side formwork frame includes a main frame 1 and an extension section 2. The extension section 2 is vertically connected to the bottom end of the main frame 1, and its end away from the main frame 1 is provided with an overlap section 23. The main frame 1 includes an inner wall 11 and an outer wall 12 arranged opposite to each other. The inner wall 11 has a concave-convex structure 111. Multiple sets of adjustment components are movably arranged on the outer wall 12. By setting the concave-convex structure 111, the facade construction 7 of the cantilever section is completed simultaneously with the pouring of the cantilever structure, simplifying the construction process and effectively saving manpower, material resources and construction time. By setting the extension section 2, it can be connected with the main formwork 5 to form the bottom formwork of the cantilever structure, effectively avoiding quality defects such as "rotten roots" and honeycomb, and improving the appearance and durability of the cantilever structure.

[0028] The aforementioned side formwork frame is used for the cantilevered end of the cantilever structure, wherein the main frame 1 is used to shape the facade structure of the cantilevered end. In this embodiment, the facade structure is the exterior facade of the building and has decorative lines and other finishing structures 7. In use, the inner wall 11 of the main frame 1 is in direct contact with the concrete of the cantilevered end. The concave-convex structure 111 is adapted to the finishing structure 7 of the facade structure. For example, the concave-convex structure 111 may include a protruding strip protruding from the main wall surface of the inner wall 11 to form a decorative groove after pouring; it may also include a groove recessed into the inner side of the wall surface to form decorative lines after pouring. Other forms of concave-convex structures 111 may also be included, without limitation; by setting concave-convex structures 111 on the inner wall 11, the decorative structure 7 of the suspended end facade structure can be constructed simultaneously when the cantilever structure is poured. Compared with the implementation method of constructing the cantilever structure first, removing the formwork and then constructing the decorative structure 7, this application simplifies the construction process, effectively saves manpower, material resources and construction time, and helps to reduce construction costs and shorten the construction period; in addition, the decorative structure 7 is integrally formed with the main structure, which has better integrity and can also effectively avoid the risk of falling off.

[0029] The aforementioned extension section 2 is used to define at least part of the bottom structure adjacent to the facade structure at the cantilever end. In a specific embodiment, the bottom of the cantilever structure is constructed by the main formwork 5 at the bottom position. This application sets an overlap section 23 to connect the extension section 2 with the main formwork 5, forming the bottom formwork of the cantilever structure together, thereby effectively avoiding the phenomenon that quality defects are prone to occur at the junction of the facade formwork and the bottom formwork in the prior art. The overlap section 23 of the extension section 2 and the main formwork 5 forms a double-layer staggered formwork structure, which can effectively avoid the phenomenon of grout leakage during concrete pouring, thereby improving the construction quality and durability of the cantilever structure.

[0030] In this embodiment, the side formwork frame is supported and fixed by a support structure. The support structure includes lateral supports and bottom supports. The lateral supports are located on the outer side of the outer wall 12 of the main frame 1 and are used to support and fix the outer wall 12 by abutting against it. An adjustment component is provided on the outer wall 12 to adjust the relative position between the main frame 1 and the lateral supports, thereby adjusting the verticality of the main frame 1 and ensuring that the verticality of the facade structure formed by the main frame 1 meets the requirements. The bottom supports are located at the bottom of the extension section 2 and the main template 5 to provide support for both.

[0031] In this embodiment, the side formwork frame is a frame structure, which has better rigidity and impact resistance than the plate-shaped formwork commonly used in the prior art. It is more conducive to ensuring the construction quality of the cantilever structure, and can be reused multiple times, thereby reducing the cost of use.

[0032] Preferably, the aforementioned side mold frame is made of aluminum alloy profile in one piece to meet the requirements of concrete lateral pressure and reusability; at the same time, the aluminum alloy profile can be extruded with a customized cross-sectional shape through mold opening, so that the concave and convex structure 111 and the inner wall 11 are integrally formed, without the need for later splicing, which is easy to process and manufacture, and has high forming accuracy; it can be mass-produced according to uniform specifications to reduce processing costs.

[0033] Furthermore, in this embodiment, a positioning groove 231 is provided on the side of the overlapping section 23 facing the inner wall 11; the overlapping section 23 is located at the end of the extension section 2 away from the main frame 1, and the positioning groove 231 is a semi-open structure, opened along the thickness direction of the overlapping section 23 and extended along the length direction of the side mold frame, and is set along the entire length; the positioning groove 231 includes a side wall surface and a bottom surface, the bottom surface of which is recessed in the direction away from the inner wall 11, for fitting and abutting against the bottom surface of the main template 5; the side wall surface is perpendicular to the bottom surface, for abutting against the side end surface of the main template 5; by setting the positioning groove 231, the main template 5 can be limited, ensuring that the two overlap accurately and the connection is reliable.

[0034] In this embodiment, the thickness of the extension section 2 is greater than the thickness of the main template 5. By opening the positioning groove 231, the thickness of the overlapping section 23 is reduced, thereby leaving space for the overlapping of the main template 5. When one end of the main template 5 is embedded in the positioning groove 231, the top surface of the main template 5 is flush with the top surface of the extension section 2.

[0035] In the above embodiment, the overlapping section 23 has sufficient thickness and rigidity. When the overlapping section 23 is pressed against the bottom support, it can further press against the main template 5, thereby providing sufficient support for the main template 5.

[0036] Furthermore, in this embodiment, a sealing strip 24 is provided in the positioning groove 231, and the sealing strip 24 is provided along the length of the side mold frame. When the extension section 2 abuts against the main template 5, the sealing strip 24 fits tightly between the two, thereby sealing the gap between the overlapping section 23 and the main template 5, improving the tightness of the connection between the two, and further preventing grout leakage.

[0037] In one specific embodiment, the seal is a compressible elastic sealing strip 24, which is a tubular structure with a cavity 13. Under the action of clamping force, it can produce uniform radial compression deformation to achieve a good sealing effect.

[0038] Preferably, the seal is made of rubber or elastomer material, the sealing compression is not less than 3mm, the sealing is reliable and not easily permanently deformed.

[0039] Furthermore, in this embodiment, the extension section 2 further includes a straight section 21, which connects the extension section 2 to the main frame 1. The straight section 21 is provided with a drip strip. Typically, a water-blocking structure is provided at the bottom of the cantilevered end of the cantilever structure, generally in the form of a drip groove 8 or a drip eave. The drip strip is used to construct the water-blocking structure. Specifically, when the drip strip is used to construct the drip groove 8, the drip strip protrudes from the end face of the straight section 21 facing the inner wall 11. When the drip strip is used to construct the drip eave, the drip strip is recessed from the end face of the straight section 21 facing the inner wall 11. By providing the drip strip, a water-blocking structure for the cantilever structure can be constructed, which can be integrally cast with the cantilever structure, further improving the ease of construction.

[0040] It is understandable that the water-blocking structure is usually installed along the length of the cantilever structure; the drip strip is installed along the length of the straight section 21.

[0041] Furthermore, in this embodiment, the main frame 1 is also provided with a cavity 13, which is divided into multiple independent spaces by reinforcing ribs 14. By providing the cavity 13 and the reinforcing ribs 14, not only can the rigidity of the main frame 1 be ensured, but the overall weight can also be reduced, making it easier to use.

[0042] Specifically, the main frame 1 includes a top plate, an inner wall 11, a bottom plate, and an outer wall 12 connected in sequence, forming a rectangular cross-section; it also includes side plates at opposite ends of the top plate, inner wall 11, bottom plate, and outer wall 12, collectively forming the aforementioned cavity 13; the reinforcing ribs 14 can be arranged parallel to the inner wall 11 or perpendicular to the inner wall 11, dividing the cavity 13 into multiple independent, enclosed spaces. The reinforcing ribs 14 and the main frame 1 are integrally manufactured.

[0043] In this embodiment, the length of the adjustment component is adjustable between the outer wall 12 and the support structure. Since the support structure is fixed, the posture of the side mold frame can be adjusted by adjusting the length of the adjustment component so that the main body of its inner wall 11 meets the verticality requirements. The adjustment component can be set at the upper and lower ends of the outer wall 12 of the side mold frame, or it can be set at one end of it.

[0044] Preferably, in this embodiment, the adjustment component is disposed at one end of the outer wall 12 near or away from the extension section 2. In use, one end of the outer wall 12 is tightly fitted onto the support structure, and the other end is abutted against the support structure by the adjustment component.

[0045] Furthermore, in this embodiment, the adjusting components are evenly spaced along the length of the side mold frame, and the resistance force of the adjusting components is evenly distributed along the length of the side mold frame, which helps to ensure that the side mold frame is subjected to balanced force and avoids lateral displacement or local deformation.

[0046] In one specific embodiment, the spacing between adjacent adjustment components is preferably 300mm to 500mm, which can achieve precise adjustment of the verticality of the side mold frame.

[0047] In one feasible technical solution of the above embodiment, the adjustment component includes a fixing nut 3 and an adjusting bolt 4; the fixing nut 3 is embedded in the outer wall 12; the adjusting bolt 4 includes a head and a rod, the rod being threadedly connected to the fixing nut 3, and the head being connected to the end of the rod located on the outside of the main frame 1. The head abuts against the lateral support, and by turning the adjusting bolt 4, it can be moved to the inner or outer side of the inner cavity of the main frame 1, thereby adjusting the length of the portion located on the outer side of the main frame 1, changing the distance between the side mold frame and the lateral support at the corresponding part, thereby achieving precise adjustment of the verticality of the main frame 1; the use of the fixing nut 3 and the adjusting bolt 4 makes the adjustment operation simple, the threaded connection can achieve self-locking, the connection stability is high, and the adjustment accuracy can reach the millimeter level.

[0048] In the above embodiment, the outer wall 12 has a certain thickness, and a groove adapted to the fixing nut 3 is provided in the thickness direction. The fixing nut 3 can be embedded in the groove and locked in place.

[0049] Preferably, the adjustment component is located at one end of the outer wall 12 near the extension section and at a suitable distance from the extension section, so that construction personnel can extend from below between the lateral support and the main frame 1 to make adjustments.

[0050] In one specific embodiment, the cantilevered sky garden 6 is constructed using the aforementioned facade design template for cantilever structures, and the construction method is as follows:

[0051] S1. Erect the supporting structure;

[0052] In this embodiment, the sky garden 6 is a cantilever structure, with one end connected to the main building and the other end suspended in the air. Its facade opposite to the main building is provided with a decorative structure 7, and the bottom of the suspended end is provided with a drip groove 8.

[0053] The supporting structure includes lateral supports and bottom supports. The bottom supports are located below the proposed location of Sky Garden 6; the lateral supports are located on the outer sides of the three facades of Sky Garden 6.

[0054] S2. Install the main template 5 and the side template frame;

[0055] The side formwork frame is set at the corresponding position on the facade with the decorative structure 7; the main formwork 5 includes the side formwork and the bottom formwork, which correspond to the bottom surface of the sky garden 6 and the other two facades, respectively; both the side formwork frame and the main formwork 5 are set on the supporting structure and are supported and fixed by the supporting structure.

[0056] When installing the bottom template, one end of the bottom template is embedded in the mounting groove of the side template frame; ensure that the bottom template and the upper surface of extension section 2 are flush.

[0057] In this embodiment, the main template 5 also includes an inner template for shaping the internal structure of the space garden; the inner template is installed after the reinforcement binding and other operations are completed.

[0058] S3. Adjust the verticality of the main frame 1;

[0059] Adjust each adjustment component in sequence and tighten the adjustment bolt 4 until the verticality of the main frame 1 meets the requirements.

[0060] After the above-mentioned templates are installed, they are checked, corrected and tightened to ensure that the templates are in the correct position and the connection is secure. Then concrete is poured and cured until the concrete reaches the required strength before the templates are removed. Figure 2 The structure of the Sky Garden 6 after the template is removed is shown in this embodiment.

[0061] The advantages and positive effects of this invention are:

[0062] (1) By setting a side formwork frame and setting a concave-convex structure on the inner wall of the main frame, the decorative structure of the suspended end facade can be constructed simultaneously when the cantilever structure is poured. Compared with the implementation method of constructing the cantilever structure first, removing the formwork and then constructing the decorative structure, the construction process is simplified, and manpower, material resources and construction time are effectively saved. This is conducive to reducing construction costs and shortening the construction period. In addition, the decorative structure is integrally formed with the main structure, which has better integrity and can also effectively avoid the risk of falling off.

[0063] (2) By setting an extension section, an installation groove is set in the extension section to overlap with the main template, and a sealing element is set in the installation groove, which can effectively prevent grout leakage during concrete pouring, thereby improving the construction quality and durability of the cantilever structure.
