Description

Technical Field

[0001] This application belongs to the field of building technology, and in particular relates to a method for prefabricated assembly construction of a baoding (a type of roof structure). Background Technology

[0002] Many existing ancient buildings possess strong aesthetic appeal and significant historical or educational value, making them suitable as landmarks or tourist attractions. Nowadays, with increasing public interest in ancient architecture, many places construct replicas of these buildings as local landmarks to attract tourists or to pray for good fortune and peace.

[0003] The ridge of a building is a representative component of ancient Chinese architecture. Originally used to protect the roof ridge from rain and other erosion, it gradually became more decorative. The materials used are mostly metal or glazed tiles. It is located in the center of the building's central axis and comes in various shapes, such as circular, waisted circular, pavilion-shaped, or pagoda-shaped, and has a rich decorative character.

[0004] In the construction of modern antique-style buildings, the installation of the finial presents several challenges: First, the large size, with some finials reaching diameters of over 2 meters and heights of around 3 meters, makes overall fabrication difficult, transportation challenging, and hoisting difficult; Second, it is difficult to balance weight, material, and durability. Concrete finials are heavy, and formwork installation requires high precision; terracotta finials are brittle and easily broken, making firing difficult and resulting in a low yield, thus leading to high production costs and hoisting difficulties.

[0005] Therefore, there is a need to provide a method for prefabricated assembly construction of the baoding section. Summary of the Invention

[0006] To address the issues of difficult installation and high manufacturing costs associated with caisson roofs, this application provides a method for constructing caisson roofs by prefabricating and assembling sections.

[0007] This application provides a method for prefabricated assembly construction of baoding blocks, including the following steps:

[0008] A) Create a building model and divide the building model into multiple standard blocks;

[0009] B) Fabricate standard blocks and a support frame for supporting the standard blocks;

[0010] C) Assemble the standard blocks, connect two adjacent standard blocks with connectors, and connect the connectors to the support frame to assemble a building shell, and the building shell can form a casting cavity that can accommodate the support frame.

[0011] D) Pour concrete into the casting cavity.

[0012] By adopting the above technical solution, the designed building model is divided into multiple standard blocks, so that the size of each standard block is relatively small, easy to manufacture, and even if a standard block is defective, the amount of scrapped material is relatively small, which can reduce the overall scrap rate and achieve the effect of saving costs. In addition, the standard blocks are small in size and light in weight, making it easy to transport or hoist them to the construction site in advance, so that they can be assembled at the construction site to form the building shell, and the building shell can serve as a casting mold for concrete pouring.

[0013] Specifically, the standard block includes a side block and a top block. When assembling the standard block, the side block is assembled first to leave a pouring opening in the upper part of the building shell, and the top block seals the pouring opening after the pouring is completed.

[0014] By adopting the above technical solution, casting can be facilitated.

[0015] Specifically, each of the standard blocks is a hollow shell structure, and each of the standard blocks is made of fired clay.

[0016] By adopting the above technical solution, the standard block is made into a hollow shell structure, which makes the standard block lightweight and easy to transport.

[0017] Specifically, each of the side blocks includes a shaping surface, a vertical connecting surface, a horizontal receiving surface, and a casting cavity connecting surface, and the vertical connecting surface, the horizontal receiving surface, and the casting cavity connecting surface are all provided with through hole structures.

[0018] By adopting the above technical solution, the building shell is formed by the side blocks and the side blocks have shaped surfaces. That is to say, the required fine shape is made when the standard blocks are prefabricated. Therefore, when assembling and pouring on the construction site, there is no need to consider the shape problem, which greatly reduces the difficulty of pouring and speeds up the construction progress. In addition, the design of the hollow shell and the design of the through hole structure can facilitate the insertion of steel bars and other connectors into the side blocks to realize the connection between adjacent side blocks, so as to ensure the stability of the building shell.

[0019] Specifically, the connectors include multiple side wall transverse connectors, multiple side wall longitudinal connectors, and multiple side wall frame connectors. The side wall transverse connectors can pass through the through-hole structure on the vertical connecting surface to connect adjacent side wall blocks in the horizontal direction. The side wall longitudinal connectors can pass through the through-hole structure on the transverse bearing surface to connect adjacent side wall blocks in the vertical direction. The side wall transverse connectors and the side wall longitudinal connectors are connected, and the position of the through-hole structure on the casting cavity connecting surface corresponds to the position of the connection portion of the side wall transverse connectors and the side wall longitudinal connectors. One end of the side wall frame connector is connected to the connection portion of the side wall transverse connectors and the side wall longitudinal connectors, and the other end is connected to the support frame.

[0020] By adopting the above technical solution, it is possible to achieve the connection between two adjacent side blocks and the connection between the side blocks and the supporting frame, thereby improving the stability of the building shell formed by the side blocks.

[0021] Specifically, a casting joint is provided between two adjacent side blocks in the horizontal direction.

[0022] By adopting the above technical solution, the stability of the connection between two adjacent side blocks can be guaranteed.

[0023] Specifically, one end of the side frame connector is connected to the support frame, and the other end can also be connected to the side transverse connector that passes through the pouring joint.

[0024] By adopting the above technical solutions, on the one hand, the stability of the building shell can be improved, and on the other hand, the pouring joint can have a steel reinforcement skeleton to ensure that the concrete in the pouring joint is not easy to fall off after the concrete is poured.

[0025] Specifically, the support frame includes a main keel, on which a plurality of overlapping rings are provided, the number of overlapping rings being greater than or equal to the number of stacked layers of the side blocks.

[0026] By adopting the above technical solution, it is easy to realize the connection between the side blocks of each layer and the supporting frame.

[0027] Specifically, the overlapping ring is provided with multiple overlapping holes, and one end of the side frame connector is connected to the overlapping holes.

[0028] By adopting the above technical solution, it is possible to fix the ends of the side frame connectors when they are connected to the support frame, thus avoiding displacement of the side block during pouring due to instability of the connection.

[0029] Specifically, the main keel is a steel column, and one end of the steel column is connected to a conductive structure, which is also connected to the ground.

[0030] By adopting the above technical solution, the main keel can act as a lightning rod.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The designed architectural model is divided into multiple standard blocks, making each standard block relatively small in size, easy to manufacture, and even if a standard block is defective, the amount of scrapped material is relatively small, resulting in a low overall scrap rate and cost savings. In addition, the small size and light weight of the standard blocks make them easy to transport or hoist to the construction site in advance, where they can be assembled to form the building shell. The building shell can also serve as a casting mold for concrete pouring.

[0033] 2. The building shell is formed by side blocks with shaped surfaces, which allows the required detailed appearance to be made when the standard blocks are prefabricated. Therefore, there is no need to consider the shape when assembling and pouring on the construction site, which greatly reduces the difficulty of pouring and speeds up the construction progress.

[0041] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0042] This application discloses a method for prefabricated assembly construction of Baoding blocks.

[0043] Reference Figure 1 and Figure 2 A method for prefabricated assembly of baoding sections, comprising the following steps:

[0044] A) Establish a building model. Taking the construction of a finial as an example, the finial is usually located at the top of the building to protect the roof ridge from rain and other erosion, as well as for decoration. Some finials are relatively large in size and weight, and are easily limited by the construction location or the lifting capacity of the hoisting equipment, making it inconvenient to hoist and install them as a whole after the overall shape is formed. Therefore, a computer can be used to digitally model the finial to be built. After the modeling is completed, BIM (Building Information Modeling) technology can be used to divide the digital model (building model) of the built finial to form multiple standard blocks 1.

[0045] Reference Figure 1 and Figure 2 When dividing the digital model of the jeweled dome, it can be divided according to the actual size and structure of the dome. For example, if the dome is a waisted circular structure, the base of the dome can be divided into one layer, the waisted part of the dome into one layer, and the spherical part of the dome into one or more layers according to its actual size. Each layer can be further subdivided into multiple standard blocks 1, so that the size of each standard block 1 is relatively small, easy to manufacture, and even if a standard block 1 is defective, the amount of scrapped material is relatively small, which can reduce the overall scrap rate and achieve the effect of saving costs. In addition, the standard block 1 is small in size and light in weight, which makes it easy to transport or hoist it to the construction position in advance, so that it can be assembled at the construction position to form the building shell, and a pouring cavity is formed in the building shell, so that the building shell can act as a pouring mold for concrete pouring.

[0046] It should be noted that a separate top block 12 should be set at the top of the finial. Then, each standard block 1 other than the top block 12 can be defined as a side block 11. In the subsequent construction process, the side blocks 11 should be assembled first so that a pouring port can be left at the top of the assembled building shell. After the pouring is completed, the top block 12 will seal the pouring port to facilitate the pouring.

[0047] B) Construct standard block 1 and support frame 2 to support standard block 1.

[0048] Creating Standard Block 1: Refer to Figure 3 and Figure 4 Each side block 11 and top block 12 in standard block 1 can be a hollow shell structure, and both side blocks 11 and top block 12 are made of clay (purple clay can be mixed into ordinary clay to improve the plasticity and surface smoothness of the clay) and fired. Of course, the top block 12 can also be a solid terracotta piece. Making standard block 1 a hollow structure makes each standard block 1 lighter in weight, easier to transport, and also allows concrete to be poured into it to improve the strength of the cast dome. Using clay to make standard block 1 gives the fired standard block 1 good air permeability. After the concrete is poured, the terracotta standard block 1 in contact with the concrete can facilitate the expulsion of moisture from the concrete to accelerate the curing of the concrete. In addition, the terracotta standard block 1 has good frost resistance and is not easy to crack in winter.

[0049] Reference Figure 3 Specifically, the side block 11 disclosed in this application embodiment includes a shaped surface 111, a vertical connecting surface 112, a horizontal supporting surface 113, and a casting cavity connecting surface 114. The shaped surface 111 is a surface with patterns or concave and convex shapes, which will serve as the outer surface of the jewel top. When making this surface, a corresponding mold can be made according to the digital model corresponding to the cover surface. For example, aluminum alloy can be milled to form a stamping mold, which can be used to stamp the kneaded clay to form the required shape. The shaped surface 111 after forming can be air-dried to a certain extent to prevent deformation when it is connected with the deformable vertical connecting surface 112, the horizontal supporting surface 113, and the casting cavity connecting surface 114. After the shaped surface 111 is connected with the deformable vertical connecting surface 112, the horizontal supporting surface 113, and the casting cavity connecting surface 114, a standard block 1 is formed. The standard block 1 then needs to be fired to make it more solid and to play a better supporting role. Through-hole structures 115 are provided on the vertical connecting surface 112, the horizontal bearing surface 113, and the casting cavity connecting surface 114, so that the connector 3 can pass through the through-hole structure 115 to form a connection between adjacent side blocks 11.

[0050] Constructing Support Frame 2: Refer to Figure 3 and Figure 4 The supporting frame 2 includes a main keel 21, on which multiple overlapping rings 22 are provided. The number of overlapping rings 22 is greater than or equal to the number of stacked layers of side blocks 11 (generally equal to or an integer multiple thereof), so as to facilitate the connection between each layer of side blocks 11 and the supporting frame 2. The overlapping rings 22 are provided with multiple overlapping holes 221, so as to facilitate the connection of one end of the relevant connector 3 to the overlapping hole 221, making it easy to fix the end of the connector 3 when connected to the supporting frame 2, thereby avoiding the displacement of the side blocks 11 during pouring due to instability of the connection. In addition, the main keel 21 can be set as a steel column, and one end of the steel column is connected to a conductive structure, which is also connected to the ground, so that the main keel 21 can act as a lightning rod.

[0051] C) Assemble standard blocks 1 by connecting two adjacent standard blocks 1 with connectors 3, and connect connectors 3 to the supporting frame 2 to assemble a building shell. The building shell should contain a casting cavity capable of accommodating the supporting frame 2. During the assembly of the building shell, assembly should proceed layer by layer from bottom to top. Specifically, refer to... Figure 4 In the same layer, the through-hole structure 115 provided on the vertical connecting surface 112 of two adjacent side blocks 11 allows the side transverse connector 31 to pass through, so as to connect the side blocks 11 in the same layer into a whole. The side transverse connector 31 can be a steel bar, and it is preferably set as a semi-circular steel bar or a one-third arc-shaped steel bar, so as to facilitate the installation and arrangement of the side transverse connector 31. The connection between the side transverse connectors 31 in the same layer can preferably be welded. During welding, the two connected side transverse connectors 31 can be welded through the through-hole structure 115 provided on the casting cavity connecting surface 114. Alternatively, there is usually a casting joint 4 between two adjacent side blocks 11 in the same layer, so the two connected side transverse connectors 31 can also be welded at the casting joint 4.

[0052] Reference Figure 3When assembling the upper side wall blocks 11 after the lower side wall blocks 11 are assembled, cement should be applied to the transverse bearing surface 113 of the lower side wall blocks 11 (it should be noted that the cement application should not block the through-hole structure 115 on the transverse bearing surface 113) to connect the two adjacent side wall blocks 11. The upper and lower side wall blocks 11 should be staggered, that is, the position of the through-hole structure 115 on the transverse bearing surface 113 of the upper side wall block 11 should correspond to the pouring joint 4 between the two adjacent lower side wall blocks 11, so that the longitudinal connecting piece 32 of the side wall can pass through the through-hole structure 115 on the transverse bearing surface 113 and the pouring joint 4. The side blocks 11 of each layer are connected to form a building shell. The longitudinal connecting member 32 of the side block can also be a steel bar. The transverse connecting member 31 and the longitudinal connecting member 32 of the side block not only serve as a connecting frame to connect the side blocks 11, but also serve as a steel bar skeleton. When concrete is poured into the side blocks 11, the transverse connecting member 31 and the longitudinal connecting member 32 of the side block can form a concrete support skeleton, which together strengthens the structural strength of the finial. The through hole structure 115 provided on the vertical connecting surface 112, the transverse bearing surface 113 and the pouring cavity connecting surface 114 can also facilitate the flow of concrete, so as to reduce the occurrence of cavities in the side blocks 11 after pouring.

[0053] The transverse side connector 31 and the longitudinal side connector 32 can be welded or tied together to improve the structural strength of the building shell and reduce deformation during the pouring process. Based on the above assembly method, the connection between the transverse side connector 31 and the longitudinal side connector 32 is generally located in the pouring joint 4 or in the cavity of the side block 11. Therefore, in order to facilitate welding or tying the connection in the cavity of the side block 11, the position of the through hole structure 115 on the pouring cavity connection surface 114 can be set to correspond to the position of the connection between the transverse side connector 31 and the longitudinal side connector 32. Specifically, taking the through hole structure 115 on the vertical connection surface 112 and the transverse bearing surface 113 as an example, the through hole structure 115 on the pouring cavity connection surface 114 should be located in the middle of the pouring cavity connection surface 114.

[0054] Finally, the side panel 11 is connected to the support frame 2. Specifically, refer to... Figure 4 and Figure 5One end of the side frame connector 33 can be connected to the connection part of the side transverse connector 31 and the side longitudinal connector 32 (including the connection part located in the pouring joint 4 and the connection part located in the cavity of the side block 11), and the other end can be connected to the lap hole 221 on the lap ring 22. The side frame connector 33 can be a steel bar, so that the side frame connector 33 and the support frame 2 can serve as the steel bar frame in the pouring cavity.

[0055] D) Pour concrete into the pouring cavity and into each side block 11; since the pouring cavity has side frame connectors 33 and support frames 2 as steel reinforcement frames, and each side block 11 and pouring joint 4 has side transverse connectors 31 and side longitudinal connectors 32 as steel reinforcement frames, the structure of the jewel top formed after pouring cement has higher strength and is less prone to cracking.

[0056] The implementation principle of the prefabricated modular assembly construction method of this application is as follows: the designed building model is divided into multiple standard blocks 1, so that the size of each standard block 1 is relatively small, easy to manufacture, and even if a certain standard block 1 is unqualified, the amount of scrapped material is relatively small, which can reduce the overall scrap rate and achieve the effect of saving costs. Since the standard block 1 is small in size and light in weight, it can be easily transported or hoisted to the construction position in advance, so that it can be assembled at the construction position to form the building shell, and the building shell can be used as a pouring mold for concrete pouring. In addition, the building shell is formed by the side blocks 11, and the side blocks 11 have a shaped surface 111, so that the required fine appearance shape is made when the standard block 1 is prefabricated. Therefore, when assembling and pouring on the construction site, there is no need to consider the shape problem, which greatly reduces the difficulty of pouring and speeds up the construction progress.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
