Description

Technical Field

[0001] The present invention relates to the technical field of garden building structures, in particular to an energy-saving construction structure of a garden building. Background Art

[0002] The information disclosed in the background of the invention is only intended to enhance understanding of the overall background of the invention and should not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0003] With the rapid development of garden landscape construction, pavilions, as important recreational and landscape nodes, are increasingly being developed for functions beyond simple sunshade and rain shelter to include energy conservation, environmental protection, mobility, and modularity. Traditional pavilions often utilize integrally cast or fixed wood and stone structures, resulting in long construction periods, significant material loss, and the lack of reusability. Furthermore, traditional pavilion roof drainage systems rely heavily on natural slopes and guttering, limiting rainwater collection efficiency due to gravity and making them inadequate for handling sudden, heavy rainfall.

[0004] In the existing technology, modular construction technology has also been applied in the field of prefabrication, but the modular design of existing pavilion-type buildings mostly focuses on rapid splicing structures, and functional integrated innovation is still insufficient.

[0005] In response to the above problems, a new energy-saving construction structure is urgently needed, which can achieve rapid assembly and disassembly while also being able to cope with rainwater collection during instantaneous heavy rainfall. Summary of the Invention

[0006] In response to the problems existing in the prior art, the purpose of the present invention is to provide an energy-saving construction structure for garden buildings. On the basis of modular prefabrication to achieve energy saving and environmental protection, the natural ventilation kinetic energy is converted into drainage driving force for rainwater collection through structural innovation, thereby improving the water collection efficiency and construction efficiency of pavilion-type buildings.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A garden building energy-saving construction structure includes a pavilion roof, wherein the pavilion roof includes a plurality of detachably connected prefabricated pavilion roof modules;

[0009] The prefabricated pavilion roof module is provided with edge strips for connection, the mating surface of the edge strips is provided with sealing grooves, and the sealing grooves are provided with expansion sealing strips;

[0010] The tops of the prefabricated pavilion roof modules are all connected and fixed to the pavilion top, and the bottoms of the prefabricated pavilion roof modules are all installed and fixed on the corresponding columns;

[0011] The prefabricated pavilion roof module is provided with corresponding water retaining edges near the bottom edge, and corresponding ventilation ducts are opened in the water retaining edges;

[0012] The prefabricated pavilion roof module is also provided with a water collection port on the side of the water retaining edge close to the pavilion tip, and the water collection port is connected to the water collection pipe located below;

[0013] The ventilation duct is connected to the water flow channel in the water collection port through a negative pressure channel, and the negative pressure channel is used to convert the ventilation kinetic energy in the ventilation duct into the drainage driving force for the water collection port to collect rainwater;

[0014] The prefabricated pavilion roof module is an autoclaved aerated concrete slab, and the water flow channel and ventilation duct are formed by fixing corresponding fusible pre-buried columns on the steel frame and melting them by heating.

[0015] Preferably, a prefabricated waterproof layer is provided on the top side surface of the prefabricated pavilion roof module.

[0016] Preferably, an upper connection plate is provided at the bottom of the pavilion tip, and a lower connection ear adapted to the upper connection plate is provided at the top of the prefabricated pavilion roof module.

[0017] Preferably, a connection block is prefabricated on the bottom side of the prefabricated pavilion roof module, and matching fixing holes are provided on the connection block and the columns.

[0018] Preferably, a positioning groove is prefabricated on the bottom side of the prefabricated pavilion roof module, and a positioning protrusion adapted to the positioning groove is provided on the top of the column.

[0019] Preferably, the lower connecting ear, the connecting block and the fixing hole are all metal embedded parts.

[0020] Preferably, a base for detachable movement is provided at the bottom of the column.

[0025] The present invention has at least the following beneficial effects:

[0026] The present invention adopts modular design and detachable installation, which improves construction efficiency, facilitates disassembly and replacement, and improves reusability and mobility.

[0027] This invention utilizes the ventilation duct within the water retaining ribs to connect with the negative pressure channel at the water collection outlet, utilizing the kinetic energy of natural wind to create a negative pressure effect, accelerating the discharge of rainwater from the water collection outlet. The multi-directional ventilation duct design ensures that rainwater collection efficiency is improved regardless of wind direction.

[0028] The present invention reduces fluid resistance and prevents internal corrosion of concrete through the protective film formed after the fusible embedded column is melted, thereby improving the durability of the ventilation duct and the water flow channel.

DETAILED DESCRIPTION

[0039] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0040] Figures 1 to 7 A landscape architecture energy-saving construction structure is presented, including a pavilion roof. The pavilion roof comprises multiple prefabricated pavilion roof modules 200 that can be detachably connected. After being factory-fabricated, these modules can be transported to the landscape site for on-site installation. To facilitate installation, the prefabricated pavilion roof modules 200 are equipped with connecting edge strips 230. The mating surfaces of these edge strips 230 have sealing grooves 250 formed therein. These sealing grooves 250 contain expansion sealing strips that expand upon contact with water, enhancing sealing. The tops of the prefabricated pavilion roof modules 200 are each connected and fixed to the pavilion apex 100, forming a circle and connecting them through the pavilion apex 100 to form a single, fixed structure.

[0041] The connection method of the top of the pavilion roof is as follows: an upper connecting plate 110 is provided at the bottom of the pavilion tip 100. The upper connecting plate 110 in this embodiment is a regular hexagonal plate. The top of the prefabricated pavilion roof module 200 is provided with a lower connecting ear 220 adapted to the upper connecting plate 110.

[0042] The bottoms of the prefabricated pavilion roof modules 200 are all installed and fixed on the corresponding columns 300, so that the bottoms of the prefabricated pavilion roof modules 200 are also installed and fixed, so that the stable installation of the pavilion roof can be achieved.

[0043] The specific fixing method of the bottom of the pavilion roof is as follows: a connection block 270 is prefabricated on the bottom side of the prefabricated pavilion roof module 200, and matching fixing holes 510 are opened on the connection block 270 and the column 300.

[0044] To facilitate installation, the prefabricated pavilion roof module 200 has a prefabricated positioning groove 260 on its bottom side, and the top of the column 300 is provided with a positioning protrusion that fits into the positioning groove 260. In this way, positioning can be performed first and then fixed, greatly improving installation efficiency and quality.

[0045] In order to improve the connection strength, the lower connection ear 220, the connection block 270 and the fixing hole 510 are all metal embedded parts.

[0046] The prefabricated pavilion roof module 200 is provided with a corresponding water retaining rib 210 near the bottom edge, and a corresponding ventilation duct 211 is opened in the water retaining rib 210; the prefabricated pavilion roof module 200 is also provided with a water collection port 240 on the side of the water retaining rib 210 close to the pavilion tip 100, and the water collection port 240 is connected to the water collection pipe 400 located below; the lower end of each vertically arranged water collection pipe 400 is connected to the horizontally arranged water collection main pipeline (not shown in the figure).

[0047] The ventilation duct 211 is connected to the water flow channel 241 in the water collection port 240 through a negative pressure channel 212, and the negative pressure channel 212 is used to convert the ventilation kinetic energy in the ventilation duct 211 into a drainage driving force for the water collection port 240 to collect rainwater. It should be noted that there are at least 3 prefabricated pavilion roof modules 200 in the present application (6 in this embodiment), so there are at least three ventilation ducts 211 set in three directions, that is, no matter which direction the wind blows from, the rainwater collection efficiency of the pavilion roof can be improved.

[0048] The prefabricated pavilion roof module 200 is an autoclaved aerated concrete slab. The water channels 241 and ventilation ducts 211 are formed by heating and melting corresponding fusible pre-embedded columns fixed to the steel skeleton. Heating here refers to the autoclaving and curing process after prefabrication. The high temperature and pressure cause the fusible pre-embedded columns to melt. The curing temperature for autoclaved aerated concrete slabs is typically 180-200°C and the pressure is 1.2-1.5 MPa.

[0049] The fusible pre-embedded column can be made of polyethylene (PE) or polypropylene (PP), which offers the best overall cost, melting point, and film-forming properties. Paraffin wax (composite modified paraffin wax) can also be used, with reinforcing agents such as nano-silica added to enhance the film's wear resistance and adhesion.

[0050] After the fusible embedded columns are heated and melted, they form protective films on the corresponding ventilation channels 211 and water channels 241 to protect the internal channels of the prefabricated pavilion roof module 200, improve the fluid passing performance, and increase its service life.

[0051] At the same time, a prefabricated waterproof layer 280 is provided on the top side surface of the prefabricated pavilion roof module 200. The prefabricated waterproof layer 280 can be a prefabricated glazed layer or a sprayed layer, which is conducive to rainwater collection, and protects the pavilion roof and improves its service life.

[0052] In another preferred embodiment, Figure 4 As shown, based on the above embodiment, the edge strips 230 are covered with an eaves cover 500. Both the eaves cover 500 and the edge strips 230 are provided with suitable mounting holes and are connected and fixed via threaded fasteners. In addition, water guide plates 520 are provided on both sides of the eaves cover 500 near the bottom to guide rainwater from the bottom corners of the prefabricated pavilion roof module 200 to the corresponding water retaining ridges 210.

[0053] The construction process and method of the energy-saving construction structure of the garden building are as follows:

[0054] S1 , first fix a vertical polygonal center column at the center of the planned construction installation location, and fix and install each column 300 . The polygonal center column is used to position the top of the prefabricated pavilion roof module 200 .

[0055] S2, then, starting with the polygonal central column as the center, start installing the corresponding prefabricated pavilion roof modules 200 one by one until all the prefabricated pavilion roof modules 200 are hoop-mounted.

[0056] S3, the polygonal central column is removed, and the pavilion tip 100, the water collecting pipe 400 and the eaves cover 500 are installed and fixed accordingly.

[0057] In another preferred embodiment, Figure 7 As shown, based on the above embodiment, the ventilation duct 211 is provided with a contraction portion 2111, and the negative pressure channel 212 is opened at the contraction portion 2111. The contraction portion 2111 is integrally formed with the fusible embedded column by a mold, and no additional processing is required after autoclaving and curing, so the process cost is controllable.

[0058] The constriction 2111 within the ventilation duct 211 features a streamlined cross-section that gradually converges and diverges (e.g., a tapered or arc-shaped constriction). When natural wind passes through this constriction 2111, the airflow velocity increases and the static pressure decreases, forming a localized area of strong negative pressure at the narrowest point (the throat) of the constriction 2111. The inlet of the negative pressure channel 212 is located at the throat of the constriction 2111, and the outlet communicates with the water flow channel 241 of the water collection port 240. This utilizes the negative pressure at the throat to directly draw rainwater from the water collection port 240. Furthermore, the negative pressure channel 212, positioned above the water collection port 240, prevents the negative pressure channel 212 from filling up with collected water and causing it to fail, significantly and steadily improving the drainage driving force.

[0059] The energy-saving construction structure of the garden building is modularly designed to facilitate processing, disassembly and installation. Therefore, it is easy to move and change the installation position. Especially after the installation is completed, it can still be replaced, which improves adaptability. Accordingly, a base for detachable movement is provided at the bottom of the column 300.

[0060] In summary, the energy-saving construction structure of the garden building includes a plurality of detachably connected prefabricated pavilion roof modules 200. The top of the module is fixed by the pavilion tip 100 and the upper connecting plate 110, and the bottom is assembled through the positioning groove 260, the connecting block 270 and the column 300, so as to achieve rapid installation and mobility.

[0061] The pavilion roof module utilizes autoclaved aerated concrete panels, with pre-embedded fusible columns that are autoclaved and cured to form ventilation ducts 211, water channels 241, and negative pressure channels 212. This utilizes natural wind energy through negative pressure to enhance rainwater collection efficiency. During construction, the central column is used for positioning, and after modular assembly, it is replaced with the pavilion apex 100 and the water collection system.

[0062] The present invention integrates modular prefabrication, wind energy-drainage linkage and lightweight environmentally friendly materials, solving the problems of long construction period and inefficient rainwater collection of traditional pavilion-type buildings. It has both ecological benefits and construction convenience, and is suitable for energy-saving transformation of garden landscapes.
