Abstract
Description
Technical Field

[0002] In construction engineering, curved structures are frequently encountered, requiring the use of curved formwork for construction. Multiple vertical joists and horizontal tie rods are installed on the outside of the formwork to maintain its shape and stability. However, this method involves a complex process of positioning and installing the vertical joists, requiring high precision and significant manpower and time. Any positional deviation can lead to insufficient tightness of the formwork when conforming to the building's curve, potentially causing grout leakage, formwork bulging, and other quality issues, affecting the final appearance and structural safety of the completed building. Furthermore, the numerous intersections between the vertical joists and horizontal tie rods create stress concentrations at these points, easily leading to formwork deformation or damage, impacting the formwork's load-bearing capacity and service life.

[0024] The embodiments of this utility model will now be described with reference to the accompanying drawings.
[0025] This utility model proposes a novel curved formwork reinforcement system for constructing curved building structures. Compared to existing methods that use vertical joists and horizontal tie rods on the outside of the curved formwork for support and reinforcement, this application enhances the vertical stiffness of the formwork itself by setting a wave structure. This eliminates a large number of vertical joist positioning and installation procedures, reduces construction difficulty and workload, and significantly improves the support efficiency of the curved formwork reinforcement system. At the same time, it also effectively improves the installation accuracy and quality of the formwork, ensuring the construction quality of the curved building structure.
[0026] like Figures 1 to 3As shown, this utility model embodiment proposes a novel curved template reinforcement system, including a template 1. The template 1 includes a first surface 11 and a second surface 12. The first surface 11 can be bent into a curved surface. The second surface 12 is provided with a wave structure 13, which has alternating wave crests 131 and wave troughs 132. The wave troughs 132 are at a set distance from the first surface 11. The wave crests 131 and wave troughs 132 are both arranged along the first direction of the template 1. The two ends of the template 1 in the second direction are provided with tenon and mortise structures for connecting adjacent templates 1. The template 1 in this embodiment has good bending deformation characteristics and can be bent into a shape that matches the curvature of the curved building structure to be constructed, so that the first surface 11 is completely fitted with the curved contour of the curved building structure to be constructed. By setting a wave structure 13 on the second surface 12 of the template 1, with the wave crests 131 and wave troughs 132 extending along the first direction of the template 1, the vertical stiffness of the template 1 itself is enhanced. The first direction usually corresponds to the height direction of the building structure during use, thus replacing the vertical keel in the prior art. This can significantly enhance the rigidity and load-bearing performance of the template 1, enabling the template 1 to resist horizontal lateral forces and making it less prone to deformation during concrete pouring. Compared with the prior art, this setting saves a lot of vertical keel positioning and installation procedures, reduces construction difficulty and workload, saves the use of vertical keels, saves materials, and significantly improves the support efficiency of the curved template 1 reinforcement system. Understandably, since the crest 131 is further away from the first surface 11, and the trough 132 is the thinnest part of the template 1, the trough 132 deforms when the template 1 is bent, causing the first surface 11 to form a curved surface. Therefore, the trough 132 is the weak point of the template 1 structure. By setting the distance between the trough 132 and the first surface 11, it can be ensured that the template 1 at this thickness has sufficient strength and will not break during deformation, thus improving the service life of the template 1. By setting the tenon and mortise structure, a quick and firm connection between adjacent templates 1 is achieved, allowing multiple templates 1 to be connected to form a larger curved surface to meet different usage requirements.
[0027] Furthermore, in this embodiment, the template 1 is integrally injection molded from thermoplastic elastic material, which has good deformability and impact resistance. Specifically, it can be made of TPEE, ETES, TPV, TPU or other materials with the same properties. During production, thermoplastic elastic material is directly used to integrally injection mold the first surface 11 and wave structure 13 of the entire template 1, which is simple to manufacture and has high production efficiency.
[0028] In this embodiment, the peaks 131 or troughs 132 are equally spaced along the second direction to ensure the consistency of deformation and performance of different parts of the template 1 in the second direction, avoid the generation of weak links, and ensure the stability caused by the curved surface formed by the first surface 11.
[0029] In one specific embodiment of this application, the cross-section of the crest 131 is an isosceles trapezoid with a flat surface away from the first surface 11. This arrangement enables a smooth transition between the crest 131 and the trough 132, improving the bending stiffness at the crest 131. Due to the set distance between the flat surface and the first surface 11, the trapezoidal structure uniformly improves the stiffness from the trough 132 to the crest 131, dispersing the lateral pressure of the concrete to the flat surface through the inclined side of the trapezoid, avoiding local stress concentration, and ensuring that the formwork 1 can form a curved surface through the deformation of the trough 132, while also ensuring that the overall curved surface has sufficient deformation resistance through the support of the crest 131.
[0030] In one specific embodiment of this application, the cross-section of the trough 132 is an isosceles trapezoid, an isosceles triangle, or a circular arc. This design enables a uniform increase in stiffness from the trough 132 to the crest 131, while also allowing the trough 132 to be easily bent and deformed, thus meeting usage requirements.
[0031] Furthermore, the length of the trough 132 along the second direction is less than the length of the crest 131 along the second direction. By shortening the length of the trough 132 and reasonably setting the length ratio of the trough 132 to the crest 131, the lateral bending stiffness and torsional stiffness of the formwork 1 can be improved, effectively preventing the formwork 1 from twisting or becoming laterally unstable during concrete pouring.
[0032] The novel curved formwork reinforcement system proposed in this application also includes tie rods 17 and transverse tie rods 16. The transverse tie rods 16 are spaced apart on the outer side of the flat surface. The tie rods 17 pass through the gaps between the transverse tie rods 16 and through the crest 131, with one end fixed to the transverse tie rod 16 by a fixing clip 18. Depending on the location and shape of the curved building structure, the tie rods 17 are used to connect two opposing formworks 1 or formwork 1 with other structures, for example, such as... Figure 4As shown, when the curved building structure is cylindrical, two curved templates 1, one inside and one outside, are needed to construct the inner and outer walls of the cylindrical structure. In this case, the tie rods 17 are used to connect and tighten the two opposite curved templates 1 so that the templates 1 are fixed in the set position. When the curved building structure is cylindrical, the curved templates 1 are connected end to end to form a circle, and the tie rods 17 are used to tie and fix the two opposite curved templates 1. When the curved building is an irregular structure with curved surfaces, the tie rods 17 are used to tie and fix the curved template 1 and another template 1 or other structure corresponding to the curved template 1. The aforementioned transverse tie rod 16 is used in conjunction with the tie rod 17 to effectively support the curved template 1. The transverse tie rod 16 is arranged along the second direction of the template 1, and can be arranged continuously or multiple transverse tie rods 16 can be arranged to adapt to the shape of the template 1. In this embodiment, the transverse tie rod 16 is made of flat steel, which can be processed and bent to form an arc that adapts to the template 1. In use, the transverse tie rods 16 are usually arranged in pairs, and multiple sets of transverse tie rods 16 are arranged at intervals along the height direction of the template 1, and are fastened to the tie rod 17 by the fixing clip 18. The aforementioned tie rod 17, fixing clip 18 and transverse tie rod 16 can all adopt common structures in the prior art, and are not limited here.
[0033] Furthermore, the trough 132 has multiple connecting holes 133 at equal intervals along the first direction, penetrating the thickness of the template 1. The tie rods 17 selectively pass through the connecting holes 133. The number of tie rods 17 is selectively set according to the height and thickness of the curved building structure. Preferably, the tie rods 17 are evenly distributed relative to the template 1, and pass through the corresponding connecting holes 133 as needed to achieve a tie connection with another curved template 1 or other structures.
[0034] To prevent concrete from overflowing from the empty connection hole 133 during pouring, a rubber plug is installed in the empty connection hole 133 to seal it and prevent grout leakage.
[0035] Furthermore, the mortise and tenon structure in this embodiment includes an insert 14 arranged along a first direction and a slot 15 adapted to the insert 14. Preferably, the lengths of the insert 14 and the slot 15 are consistent with the length of the template 1 along the first direction. The thickness of the insert 14 is less than the thickness of the main body of the template 1. The opening of the slot 15 faces the second direction of the template 1. The width of the insert 14 is adapted to the depth of the slot 15. The insert 14 can be inserted into the slot 15 through the opening. The slot 15 can clamp the insert 14. The friction between the insert 14 and the slot 15 is used to fix the insert 14 to the inside of the slot 15. With this setting, the extension of the template 1 along the first direction can be completed quickly and conveniently, while avoiding the formation of through gaps in the connection parts of adjacent templates 1, thus improving the airtightness of the joint.
[0036] The advantages and positive effects of this utility model are:
[0037] (1) The template in this application adopts a wave structure, which can effectively enhance the vertical stiffness of the template, thus replacing the vertical keel in the prior art, saving a lot of vertical keel positioning and installation procedures, reducing construction difficulty, reducing workload, saving materials, and improving construction efficiency; by setting the distance between the trough and the first surface, it can be ensured that the template at this thickness has sufficient strength and will not break during deformation, thus improving the service life of the template and ensuring construction quality.
[0038] (2) By setting mortise and tenon structures at both ends of the template, a quick and firm connection between adjacent templates is achieved. The template can be extended as needed, while avoiding through gaps in the connection between adjacent templates, thus improving the airtightness of the joint.
[0039] (3) The template in this application is easy to install and disassemble, has low cost, good load-bearing capacity, can be bent into curved surfaces of different curvatures as needed, has wide applicability, and is easy to reuse.
