[0023] In the existing construction formwork splicing process, the two adjacent construction formwork pieces cannot be effectively matched, making it difficult to avoid gaps between the two construction formwork pieces, which further leads to defects such as grout leakage, uneven forming surface, etc.
[0024] This invention proposes a combined splicing template.
[0025] Please see Figure 1 In one embodiment of the present invention, the combined splicing template includes: multiple templates and multiple fastening components. The multiple templates are arranged along the circumferential direction, and mating parts are respectively provided on both sides of the template width direction. In two adjacent templates, the mating part of one template cooperates with the mating part of the other template, the two mating parts mesh with each other, and the included angle between two adjacent templates is adjustable. At least one fastening component is provided between two adjacent templates, and the fastening component is used to fix the two adjacent templates together.
[0026] The technical solution of this invention adopts a structural design with interlocking mating parts on both sides of adjacent templates, which enables stable docking of adjacent templates through the interlocking of the mating parts. The included angle between adjacent templates can be flexibly adjusted according to the casting requirements to adapt to casting operations of different shapes. With the fastening components, the adjacent templates are fixed and locked, avoiding relative displacement of the templates after splicing, eliminating the splicing gaps between adjacent templates, effectively solving the problems of easy leakage of grout and uneven forming surface of components after splicing, and improving the quality of casting.
[0027] Specifically, the mating part is configured as follows: one side of the template protrudes to form a convex portion, the outer surface of which is an arc surface. The template includes multiple limiting teeth, which are fixedly disposed on the convex portion along the circumferential direction. The convex portion and the multiple limiting teeth together constitute the mating part. When two adjacent templates mate, the convex portion of one template can fit and align with the corresponding mating structure on the side of the other template. The limiting teeth engage sequentially and alternately. To adjust the included angle, only one template needs to be rotated around the arc center of the convex portion to change the relative angle between the two templates. After adjusting to the preset angle, all limiting teeth re-engage and lock together, and then the fastening assembly completes the locking and fixing.
[0028] To further prevent gaps, a sealant is applied between the two meshing parts that interlock, preventing grout leakage. When the limiting teeth interlock and lock, the sealant fills the tiny gaps between the teeth and the meshing surfaces, preventing grout from seeping out of the meshing area even under significant lateral pressure during concrete pouring. Simultaneously, the sealant has a certain deformation capacity, which does not affect the adjustment of the template angle or hinder the normal meshing of the limiting teeth. After the angle is adjusted and locking is completed, the sealant adheres to the meshing structure under pressure, maintaining a continuous sealing effect, further enhancing the grout leakage prevention performance at the joint, and better ensuring the forming accuracy and surface quality of the cast components.
[0029] To maintain a fixed angle between adjacent template pieces: the template includes multiple limiting holes, which penetrate both sides of the template in the thickness direction and are spaced apart along the height direction. The extending direction of the limiting holes is perpendicular to the height direction, and the angle between the extending direction of the multiple limiting holes and the end face of the template in the thickness direction increases sequentially (see [reference]). Figure 2 The fastening assembly includes a limiting rod, which passes through two corresponding limiting holes on two adjacent templates to fix the included angle of the two templates. The limiting rod passes through both templates simultaneously, preventing them from meshing or rotating. Compared to traditional angle adjustment structures, this fixing method using limiting holes and limiting rods is simple in structure, easy to manufacture, and convenient to assemble on-site. It allows for quick angle positioning and fixing without the need for complex additional positioning fixtures. Simultaneously, the limiting rod passes through the corresponding limiting holes of both templates, evenly bearing the lateral pressure generated during concrete pouring, preventing localized stress concentration that could lead to template deformation, further ensuring the stability of the included angle, and adapting to different pouring angle requirements in various construction scenarios.
[0030] The limiting rod passes through two templates simultaneously, preventing the two templates from meshing and rotating, but the two templates can still slide relative to the limiting rod.
[0031] In one embodiment, the limiting rod includes a screw, and the fastening assembly further includes two nuts, each corresponding to one end of the screw and abutting against the corresponding template, thereby securing adjacent templates together. This screw-and-nut locking structure quickly locks the relative position of the limiting rod and the two templates after angle positioning, preventing the templates from sliding or shifting along the limiting rod during pouring, further improving the stability of the overall structure. Simultaneously, the locking operation only requires tightening the nuts at both ends, eliminating the need for additional modifications to the original template structure. Assembly and disassembly are very convenient, and both the nuts and screw can be recycled and reused after construction, reducing construction costs.
[0032] In an alternative embodiment, the limiting rod includes a screw, and the limiting hole includes a threaded hole. The screw and the limiting holes of both templates are connected via a threaded engagement. Rotating the screw causes the two templates to move closer or further apart along the screw direction. After the angle adjustment is completed, the template position can be fixed directly by the locking characteristics of the thread itself, eliminating the need for additional locking components. This further reduces the number of components required and simplifies the splicing and locking process. Simultaneously, the engagement stability between the screw and the threaded hole is stronger, better resisting the lateral thrust generated by concrete pouring and preventing relative displacement of the templates.
[0033] Since the building height may be greater than the height of a single template, the templates need to be stacked in the height direction to meet the building requirements: multiple templates are arranged in a circumferential direction to form a splicing layer, and the splicing layer has multiple layers and is stacked in the height direction.
[0034] To prevent the upper template from shifting or tipping over: Please refer to... Figure 3 The combined splicing template also includes insert rods that extend along the height direction. Insert rods are positioned between two adjacent splicing layers and between two templates corresponding to each other in the height direction, with each end of the insert rod interlocking with one of the two templates. This interlocking connection method precisely limits the horizontal displacement between the upper and lower template layers, preventing misalignment of the upper template during splicing or pouring. It also provides vertical positioning constraints for the stacked template as a whole, effectively reducing the risk of the upper template tipping over. Furthermore, the interlocking operation between the insert rods and the template is simple, requiring no additional complex connecting components. Construction workers can quickly complete the alignment and splicing of the upper and lower template layers, ensuring the overall stability of the stacked structure without increasing construction difficulty or material costs, further adapting to the pouring requirements of curved components in high-rise buildings.
[0035] To prevent grout from leaking out from the joint between the upper and lower splicing layers, the template has opposing inner and outer surfaces in the thickness direction. The inner surface faces the center of the splicing layer, and the end faces of two adjacent splicing layers that abut against each other extend from high to low in the direction from the outer surface to the inner surface. This inclined end face structure allows the upper and lower splicing layers to fit more tightly. When the upper and lower splicing layers press against each other, the inclined end faces increase the contact area between the two template layers. At the same time, the pressure of the poured grout increases the tightness of the joint, effectively sealing the channels for grout leakage and preventing grout leakage during construction, thus ensuring the forming quality of the curved component after pouring. Moreover, this sealing structure is achieved directly through the processing of the template end faces, without the need for additional sealing materials. While solving the grout leakage problem, it does not increase additional construction procedures or material costs.
[0036] The combined splicing template structure also includes a reinforcing plate, which is specifically disposed between two adjacent splicing layers and corresponds to the corresponding templates in the two splicing layers in the height direction. Its function is to firmly connect with the two templates, thereby enhancing the stability and load-bearing capacity of the overall structure.
[0037] The reinforcing plate covers the outside of the joint between the upper and lower splicing layers, providing additional support to the splicing area and preventing the joint from opening and deforming under the pressure of pouring, further reducing the risk of grout leakage. The reinforcing plate can be quickly connected to the formwork using clips or bolts, simplifying the installation process without affecting the overall construction progress. It is also reusable, meeting the cost control requirements of engineering construction.
