Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction. More specifically, this utility model relates to a rodless support structure for curved wooden formwork. Background Technology

[0002] As people's demands for architectural aesthetics and functionality increase, the design of building structures is becoming increasingly diversified and complex, leading to a greater application of irregularly shaped components, for example... Figure 1 The small-radius curved wooden formwork shown is shaped like part of a frustum cylinder. Multiple pieces of this small-radius curved wooden formwork can be spliced ​​together to form a hollow frustum. These irregularly shaped components not only add a unique visual effect to the building but also meet specific functional requirements. However, this also poses greater challenges to concrete pouring and formwork support during construction.

[0003] During concrete pouring, the stability of the supporting structure is crucial for ensuring the construction quality of irregularly shaped components. An unstable supporting structure may lead to deformation and cracking during concrete pouring, thus affecting the overall performance and durability of the component. Therefore, during construction, it is essential to fully consider the characteristics of the irregularly shaped component and the requirements of concrete pouring, selecting appropriate supporting materials and structural forms to guarantee the construction quality of the component. Figure 1 The small-radius curved wooden template shown has the following main problems:

[0004] 1. The main beams of the curved timber formwork are difficult to process, and the overall integrity of the main beams is poor.

[0005] 2. The main support behind the back rib needs to be densely installed, which makes it difficult for personnel to operate in the limited working space.

[0006] 3. When using straight lines to replace curved lines for formwork support, the formwork support and the formwork do not fit together, resulting in deformation of the component after casting.

[0007] 4. Some fair-faced concrete buildings do not have surface coatings, so in order to prevent rust channels from forming, it is not possible to fix the formwork by setting tie rods. Utility Model Content

[0008] The purpose of this utility model is to address the above-mentioned problems by providing a rodless support structure for curved wooden formwork.

[0009] To achieve these objectives and other advantages according to this utility model, a rodless support structure for curved wooden formwork is provided, comprising:

[0010] The template is a curved panel;

[0011] Multiple back ribs are evenly distributed on the inner side of the template along the curved surface extension direction of the template.

[0012] Multiple main ribs are axially spaced on the side of the multiple back ribs away from the template. The main ribs and the back ribs are arranged intersectingly. The main ribs are connected to at least one of the back ribs through a connecting assembly.

[0013] Furthermore, in the aforementioned curved wooden formwork support structure without tie rods, the main rib is an arc-shaped steel bar.

[0014] Furthermore, in the aforementioned curved wooden formwork support structure without tie rods, the connecting assembly includes multiple connecting units spaced apart along the length direction of the main rib.

[0015] Furthermore, in the aforementioned curved wooden formwork support structure without tie rods, the connecting unit includes:

[0016] Two limiting members are disposed vertically on one of the back ribs, and a clamping position for fixing the main rib is formed between the two limiting members.

[0017] Furthermore, in the aforementioned curved wooden formwork support structure without tie rods, multiple main ribs are arranged in pairs.

[0018] Furthermore, in the aforementioned curved wooden formwork without tie rod support structure, the formwork is composed of multiple bamboo plywood panels spliced ​​together.

[0019] Furthermore, in the aforementioned curved wooden formwork support structure without tie rods, the two ends of the formwork are respectively evenly distributed with multiple first mounting positions and multiple second mounting positions along the circumference, and one end of the multiple back ribs is located in multiple first mounting positions in sequence, and the other end is located in multiple second mounting positions in sequence.

[0020] Furthermore, in the aforementioned curved wooden formwork support structure without tie rods, the back ribs are connected to the formwork via steel nails.

[0021] Furthermore, in the aforementioned curved wooden formwork support structure without tie rods, the main rib and the back rib are perpendicular to each other.

[0022] Furthermore, the aforementioned curved wooden formwork support structure without tie rods also includes:

[0023] Two main beam fixing beams are located on both sides of the multiple main beams, and the two ends of the main beams are respectively connected to the two main beam fixing beams.

[0024] The beneficial effects of this utility model are:

[0025] 1. In the curved wooden formwork without tie rod support structure of this utility model, tie rods are not used when fixing the main rib, thereby avoiding the occurrence of channel corrosion when fixing the formwork by setting tie rods.

[0026] 2. The curved wooden formwork of this utility model has a simple structure without tie rod support. Its main ribs are easy to process and do not need to be densely arranged, which facilitates operation by personnel in a limited working space.

[0035] like Figures 2-3 As shown, an embodiment of this utility model provides a rodless support structure for a curved wooden formwork 1, comprising:

[0036] Template 1 is a curved panel;

[0037] Multiple back ribs 2 are evenly distributed on the inner side of the template 1 along the curved extension direction of the template 1;

[0038] Multiple main ribs 3 are spaced axially on the side of the multiple back ribs 2 away from the template 1. The main ribs 3 are arc-shaped steel bars that fit the inner arc of the template 1. The main ribs 3 and the back ribs 2 are arranged intersectingly. The main ribs 3 and the back ribs 2 are perpendicular to each other. The main ribs 3 are connected to at least one of the back ribs 2 through a connecting component.

[0039] In this embodiment, the back rib 2 is made of square timber, cut to the designed length of the template 1. The back rib 2 is attached to the inner side of the template 1 and fixed to the template 1 with steel nails. Then, multiple steel bars of appropriate size are selected and bent into main ribs 3 according to the installation position. This facilitates the processing and shaping of the steel bars, and the processed main ribs 3 have good overall integrity. The main ribs 3 behind the back rib 2 do not need to be densely arranged. The predetermined installation position of the main ribs 3 is determined according to actual needs, facilitating operation within a limited working space. Before installing the main ribs 3, the connecting components are first connected to the back rib 2, and then the main ribs 3 are connected to the connecting components. The clamping components are used to fix each main rib 3 to the back rib 2, completing the installation of the template 1. In the small-radius curved wooden template 1 support structure of this embodiment, multiple main ribs 3 bear the load received by the entire template 1, and the back rib 2 plays a role in transferring the panel load to the main ribs 3, acting as a connecting link.

[0040] Preferably, in another embodiment of the present invention, the connecting component includes a plurality of connecting units spaced apart along the length direction of the main rib 3.

[0041] In this embodiment, the clamping assembly includes multiple clamping units 4, which are distributed in a dispersed manner and apply force to the main rib 3 respectively, so that the main rib 3 is subjected to more uniform force.

[0042] Preferably, in another embodiment of the present invention, the connecting unit includes:

[0043] Two limiting members are disposed vertically on one of the back ribs 2, and a clamping position for fixing the main rib 3 is formed between the two limiting members.

[0044] In this embodiment, when installing the limiting component, a laser locator or other method is used to fix the limiting component to the designed elevation position on the back rib 2 with steel nails.

[0045] Preferably, in another embodiment of the present invention, the multiple main ribs are arranged in pairs.

[0046] In this embodiment, multiple main beams 3 are arranged in pairs, dividing the main beams 3 into multiple groups. There is a large gap between adjacent groups of main beams 3, which facilitates operation by personnel in a limited working space.

[0047] Preferably, in another embodiment of the present invention, the template 1 is made of multiple pieces of bamboo plywood spliced ​​together.

[0048] In this embodiment, template 1 is made of multiple pieces of bamboo plywood spliced ​​together, which makes it easy to process template 1 according to the design dimensions.

[0049] Preferably, in another embodiment of the present invention, the template 1 has a plurality of first mounting positions and a plurality of second mounting positions evenly distributed around its two ends in the circumferential direction, and one end of the plurality of back ribs 2 is located in a plurality of first mounting positions in sequence, and the other end is located in a plurality of second mounting positions in sequence.

[0050] In this embodiment, such as Figure 2 As shown, one end of the multiple back ribs 2 is located in multiple first mounting positions in sequence, and the other end is located in multiple second mounting positions in sequence. This allows the multiple back ribs 2 to be evenly distributed on the inner side of the template 1, making the template 1 more uniformly stressed.

[0051] Preferably, as another embodiment of the present invention, it further includes:

[0052] Two main beam fixing beams 5 are located on both sides of the multiple main beams 3, and the two ends of the main beams 3 are respectively connected to the two main beam fixing beams 5.

[0053] In this embodiment, the main rib fixing beam 5 is connected to multiple main ribs 3 by welding or other means, so that the multiple main ribs 3 are connected into a whole. The main rib fixing beam 5 can be fixed by setting a fixed bracket on the ground, or it can be rigidly connected and fixed to the pre-embedded device set in the adjacent structure, thus completing the fixing of the template 1.

[0054] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
