AI Technical Summary
Traditional antique-style wooden eaves structures are prone to being overturned by wind loads in high-rise buildings or in cases where the cantilever length is too long. Existing structural systems are insufficient to resist this effect.
The structure combines a concrete ring beam with wooden eaves. Wind loads are transferred through the connection between the eaves and the ring beam. Reinforcing steel bars are placed inside the eaves to enhance the overall structural strength. The eaves and wooden eaves form a self-locking effect to prevent overturning.
It effectively transfers the wind load on the eaves to the main structure of the building, preventing the wooden structure from being overturned under the action of wind load, while maintaining the facade effect of the antique building.

Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, specifically to an ultra-high cantilevered eaves structure for antique-style buildings and its construction method. Background Technology
[0002] Conventional antique-style wooden facade structures typically transfer vertical loads directly to the wooden columns through their own system of wooden eaves, brackets, and columns. The wooden columns, connected to the concrete base slab, then transfer the vertical loads to the main structure. Horizontal loads are also transferred directly to the main structure through the connection between the wooden facade structure and the frame columns and beams. However, in high-rise buildings or when the horizontal cantilever of the wooden eaves is excessively long, while the self-weight load can still be transferred through the system of wooden eaves, brackets, and columns, the structural system itself may be insufficient to withstand the upward toppling effect of wind loads on the wooden eaves at high altitudes.
[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies, a super-tall cantilevered eaves structure and construction method for antique-style buildings are provided to solve the problem that traditional antique-style wooden eaves structures are prone to overturning when the cantilever length of the eaves structure is too long in high-rise buildings or eaves structures.
[0005] To achieve the above objectives, an ultra-high cantilevered eaves structure for antique-style buildings is provided, comprising:
[0006] A concrete structure, including a ring beam and an eaves board, wherein the ring beam is connected to the frame column of the building structure, the ring beam is arranged in a circle along the circumferential direction of the building structure, the ring beam is arranged above the first-floor frame beam of the building structure, the outer side of the ring beam extends obliquely outward and downward to form the eaves board, and the upper part of the eaves board is covered with a finishing layer;
[0007] The wooden eaves have a dovetail groove at the top and a tenon at the bottom. The shape and size of the tenon are adapted to the shape and size of the dovetail groove, and the tenon is inserted into the dovetail groove.
[0008] Wooden brackets are installed on the outside of the first-floor frame beams and supported by the wooden eaves;
[0009] The wooden columns are erected on the cantilevered balcony slab and supported by the wooden brackets. The lower frame beam of the first-layer frame beam is cast to form a cantilevered balcony slab.
[0010] Furthermore, the tenon is provided along the width direction of the eaves board.
[0011] Furthermore, there are multiple tenons, which are spaced apart along the length of the eaves board.
[0012] Furthermore, the finishing layer includes a keel fixed to the upper part of the eaves and finishing tiles laid on the keel.
[0013] Furthermore, an anchor is pre-embedded in the upper part of the eaves board, the anchor extending above the eaves board and connected to the keel.
[0014] Furthermore, a steel reinforcement structure is embedded within the tenon, and one layer of the steel reinforcement structure is anchored to the lower part of the eaves board.
[0015] This invention provides a construction method for an ultra-high cantilevered eaves structure of an antique-style building, comprising the following steps:
[0016] Construction of building structure, wherein the building structure is a concrete frame structure;
[0017] A ring beam is formed by casting the frame columns of the building structure. The ring beam is arranged in a circle along the circumference of the building structure. The ring beam is set above the first-floor frame beam of the building structure. The lower frame beam of the first-floor frame beam is cast to form a cantilevered balcony slab.
[0018] The wooden pillars are erected on the cantilevered balcony slab;
[0019] The wooden brackets are installed on the outside of the first-floor frame beams, and the wooden columns are supported by the wooden brackets;
[0020] Wooden eaves are installed with the wooden brackets, and the wooden brackets are supported by the wooden eaves;
[0021] An eaves board is cast on the wooden eaves, the eaves board is connected to the ring beam, and the tenon formed by the eaves board is inserted into the dovetail groove of the wooden eaves;
[0022] A finishing layer is laid on the upper part of the eaves.
[0023] The beneficial effects of this invention are as follows: The ultra-high cantilevered eaves structure of the antique-style building of this invention replaces ordinary wooden eaves with a wood-concrete composite eaves and sets up a ring beam. Through the overall structural stress, the upward wind load on the eaves is effectively transferred to the ring beam through the concrete slab, and then from the ring beam to the main structure of the building. An eaves board is set above the wooden eaves, with steel bars inside the eaves board and cast and connected to the ring beam to ensure that the eaves board can withstand the upward wind load and avoid the overturning effect of the eaves. At the same time, the eaves board should slope outward and downward with the wooden eaves to ensure close fit between the eaves board and the wooden eaves. The downward slope of the eaves board can also form a self-locking effect on the wooden structure system of wooden eaves-wooden brackets-wooden columns below, preventing the wooden structure system from overturning upward or outward under wind load. On the other hand, the eaves board and the wooden eaves form a concrete-wood composite structure through dovetail joints and tenons. The ultra-high cantilevered eaves structure of the antique-style building of this invention sets up a finishing layer of upper eaves tiles and other decorative elements above the concrete eaves board. The finishing layer is connected to the eaves using pre-embedded anchors. The finishing layer is installed to cover the eaves to ensure the antique architectural effect from the exterior facade.

[0037] The wooden eaves 2 are made of wood. A dovetail groove is formed at the top of the wooden eaves 2. A tenon 121 is formed at the bottom of the eaves board 12. In this embodiment, the tenon is a concrete structure. The tenon and the eaves board are integrally cast.
[0038] The dovetail groove has a trapezoidal cross-section. The shape and size of the tenon are adapted to the shape and size of the dovetail groove. The tenon is inserted into the dovetail groove.
[0039] As a preferred embodiment, the tenon strip is provided along the width direction of the eaves panel 12.
[0040] In this embodiment, there are multiple tenons. These multiple tenons are spaced apart along the length of the eaves panel 12. Each tenon has a trapezoidal cross-section.
[0041] In a preferred embodiment, a steel reinforcement structure is embedded within the tenon 121. One layer of the steel reinforcement structure is anchored to the lower part of the eaves 12.
[0042] Specifically, the steel reinforcement structure of the tenon includes two main bars and stirrups placed outside the two main bars. One layer of stirrups is anchored in the concrete at the bottom of the eaves.
[0043] Wooden bracket set 3 is installed on the outside of the first-floor frame beam. Wooden bracket set 3 supports the wooden eaves 2. The lower part of the wooden bracket set is installed on the outside of the first-floor frame beam.
[0044] The lower frame beam 6 of the first-floor frame beam is cast to form a cantilevered balcony slab 61. Wooden columns 4 are erected on the cantilevered balcony slab 61 and supported by wooden brackets 3.
[0045] Continue reading Figure 2 The finishing layer 13 includes a keel fixed to the upper part of the eaves board 12 and finishing tiles laid on the keel.
[0046] In this embodiment, an anchor is pre-embedded in the upper part of the eaves board 12. The anchor extends above the eaves board 12 and is connected to the keel.
[0047] This invention provides a construction method for an ultra-high cantilevered eaves structure of an antique-style building, comprising the following steps:
[0048] S1: Construction building structure, the building structure is a concrete frame structure.
[0049] S2: A ring beam 11 is formed by casting the frame column 5 of the building structure. The ring beam 11 is set in a circle along the circumference of the building structure. The ring beam 11 is set above the first-floor frame beam of the building structure. The lower frame beam of the first-floor frame beam is cast to form a cantilevered balcony slab 61.
[0050] S3: The eaves board 12 is formed by casting the eaves board 12 by extending it obliquely outward and downward on the outside of the ring beam 11.
[0051] S4: Erect the wooden column 4 on the cantilevered balcony slab 61.
[0052] S5: Install the wooden bracket 3 on the outside of one side of the frame beam, and the wooden column 4 supports the wooden bracket 3.
[0053] S6: The wooden eaves 2 are placed at the bottom of the eaves board 12, the tenons of the eaves board 12 are inserted into the dovetail grooves of the wooden eaves 2, and the wooden brackets 3 are supported by the wooden eaves 2.
[0054] S7: A decorative layer 13 is laid on the upper part of the eaves board 12.
[0055] The present invention relates to an ultra-high cantilevered eaves structure for antique-style buildings. A concrete ring beam is added between the frame columns of each eaves and bracket layer of the antique-style building structure. The ring beam is connected to the frame columns on both sides using conventional concrete beam-column joints. The reinforcement and concrete strength of the ring beam must fully consider the structural stress requirements, such as the horizontal load transmitted from the wooden eaves of the exterior facade and the torque generated by the upward wind load.
[0056] An eaves board is installed above the wooden eaves, with reinforcing steel bars embedded within it and connected to the cast-in-place ring beam to ensure the eaves board can withstand upward wind loads. Simultaneously, the eaves board should slope outwards and downwards along with the wooden eaves to ensure a close fit between the eaves board and the eaves. This downward slope also creates a self-locking effect on the underlying wooden eaves-bracket-column structure, preventing the wooden structure from being lifted upwards or outwards under wind loads. Furthermore, the eaves board and the wooden eaves form a concrete-wood composite structure through dovetail joints and tenons.
[0057] The present invention relates to a super-tall, cantilevered eaves structure of an antique-style building, on which a decorative layer of upper eave tiles and other decorations is provided above the concrete eaves slab. The decorative layer is connected to the eaves slab by pre-embedded anchors. The decorative layer is used to cover the eaves slab to ensure the antique-style architectural effect from the exterior facade.
[0058] In the construction of the super-tall cantilevered eaves structure of the antique-style building of this invention, the concrete structure is first constructed along with the ring beam during the main structure construction process. After the complete main structure is completed, the construction of wooden columns, wooden brackets, and wooden eaves is carried out in sequence according to the conventional wooden structure construction sequence. After the wooden eaves are installed, the remaining steel bars of the eaves board and the steel bars of the wooden eaves groove should be installed in a timely manner, and concrete should be poured. The pouring of the eaves board should use concrete or grout with good fluidity to ensure that it fills the groove of the wooden eaves, so that the wooden eaves and the eaves board form an integral composite structure. If necessary, concrete with certain micro-expansion properties can be used to further enhance the bonding performance between the wooden eaves and the eaves board. Before the eaves board is poured, the connectors should be pre-embedded as needed, and after the concrete reaches a certain strength, the construction of the upper tiles and other decorations of the eaves is completed to conceal the eaves board.
[0059] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
