[0003] With the rapid development of garden landscape construction, pavilion buildings, as important rest and landscape nodes, their functional requirements are gradually extending from single sunshade and rain shelter to energy conservation, environmental protection, mobility, and modularization. Traditional pavilion buildings mostly adopt integral casting or fixed wooden and stone structures, which have problems such as long construction periods, large material losses, and non-reusability. In addition, the traditional pavilion roof drainage system mostly relies on natural slopes and water guide grooves, and the rainwater collection efficiency is limited by gravity and it is difficult to cope with instantaneous heavy rainfall.

[0004] In the prior art, modular building technology has also been applied in the prefabrication field, but the modular design of existing pavilion buildings mostly focuses on quick splicing structures, and there is still insufficient functional integration and innovation.

[0005] In view of the above problems, there is an urgent need for a new type of energy-saving construction structure that can achieve quick assembly and disassembly, and at the same time can cope with the rainwater collection of instantaneous heavy rainfall. Summary of the Invention

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an energy-saving construction structure for garden buildings, which, on the basis of realizing energy conservation and environmental protection through modular prefabrication, converts the kinetic energy of natural ventilation into the drainage driving force for rainwater collection through structural innovation, thereby improving the water collection efficiency and construction efficiency of pavilion buildings.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present invention will be further described below in conjunction with specific embodiments and the drawings.

[0025] Figures 1 to 7A garden building energy-saving construction structure is presented, including a pavilion top. The pavilion top includes a plurality of prefabricated pavilion top modules 200 that are detachably connected. After being processed in the factory, they can be transported to the garden site for on-site installation. To achieve installation connection, the prefabricated pavilion top module 200 is provided with a side strip 230 for connection. A sealing groove 250 is opened on the mating surface of the side strip 230, and an expansion sealing strip is arranged in the sealing groove 250, which expands when encountering water to make its sealing performance better. The tops of the prefabricated pavilion top modules 200 are all connected and fixed to the pavilion tip 100, so that the tops of the prefabricated pavilion top modules 200 form a circle and are connected into an integral fixed structure through the pavilion tip 100.

[0026] The connection method at the top of the pavilion top is as follows: A upper connection plate 110 is arranged at the bottom of the pavilion tip 100. In this embodiment, the upper connection plate 110 is a regular hexagonal plate, and a lower connection ear 220 adapted to the upper connection plate 110 is arranged at the top of the prefabricated pavilion top module 200.

[0027] The bottoms of the prefabricated pavilion top modules 200 are all installed and fixed on the corresponding columns 300, so that the bottoms of the prefabricated pavilion top modules 200 are also installed and fixed. In this way, the stable installation of the pavilion top can be achieved.

[0028] The specific fixing method at the bottom of the pavilion top is as follows: A connection block 270 is prefabricated on the bottom side of the prefabricated pavilion top module 200, and matching fixing holes 510 are opened on both the connection block 270 and the column 300.

[0029] To facilitate installation, a positioning groove 260 is prefabricated on the bottom side of the prefabricated pavilion top module 200, and a positioning protrusion adapted to the positioning groove 260 is arranged at the top of the column 300. In this way, after positioning, fixing can be carried out, greatly improving the installation efficiency and installation quality.

[0030] To improve the connection strength, the lower connection ear 220, the connection block 270 and the fixing hole 510 are all metal embedded parts.

[0031] The corresponding water retaining edges 210 are arranged near the bottom edge of the prefabricated pavilion top module 200, and corresponding ventilation ducts 211 are opened in the water retaining edges 210; A water collecting port 240 is also arranged on the prefabricated pavilion top module 200 on the side of the water retaining edge 210 close to the pavilion tip 100, and the water collecting port 240 is connected to the water collecting pipe 400 located below; The lower ends of each vertically arranged water collecting pipe 400 are all connected to a horizontally arranged water collecting main pipe (not shown in the figure).

[0032] The ventilation duct 211 is connected to the water flow channel 241 in the water collection port 240 through a negative pressure channel 212. The negative pressure channel 212 is used to convert the ventilation kinetic energy in the ventilation duct 211 into the drainage driving force for rainwater collection at the water collection port 240. It should be noted that in this application, there are at least three or more prefabricated pavilion top modules 200 (six in this embodiment). Therefore, there are ventilation ducts 211 arranged in at least three or more directions. That is to say, no matter which direction the wind blows from, the rainwater collection efficiency of the pavilion top can be improved.

[0033] The prefabricated pavilion top module 200 is an autoclaved aerated concrete board. The water flow channel 241 and the ventilation duct 211 are both formed by corresponding fusible embedded columns fixed on the steel bar skeleton and melted by heating. Here, the so-called heating refers to autoclave curing after prefabrication, and the high temperature and high pressure cause the fusible embedded columns to heat and melt. Among them, the curing temperature of the autoclaved aerated concrete board is usually 180 - 200 °C and the pressure is 1.2 - 1.5 MPa.

[0034] The material of the fusible embedded column can be polyethylene (PE) or polypropylene (PP), which has the best comprehensive cost, melting point and film-forming performance. Paraffin (composite modified paraffin) can also be selected, and by adding reinforcing agents such as nano-silica, the wear resistance and adhesion of the film layer can be improved.

[0035] After the fusible embedded column is heated and melted, a protective film is formed in the corresponding ventilation duct 211 and water flow channel 241 to protect the internal channels of the prefabricated pavilion top module 200, improve the fluid passing performance, and extend its service life.

[0036] At the same time, a prefabricated waterproof layer 280 is provided on the top side surface of the prefabricated pavilion top module 200. The prefabricated waterproof layer 280 can be a prefabricated glazed layer or a sprayed layer, which is beneficial to rainwater collection, protects the pavilion top, and extends its service life.

[0037] In another preferred embodiment, as Figure 4 shown, on the basis of the above embodiment, a cornice sleeve 500 is sleeved outside the side strip 230. The cornice sleeve 500 and the side strip 230 are both provided with matching mounting holes and are connected and fixed by threaded fixing parts. And, water guide plates 520 are arranged on both sides near the bottom of the cornice sleeve 500, which are used to guide the rainwater at the bottom corners of the prefabricated pavilion top module 200 to the corresponding water retaining edges 210.

[0038] The construction process and method of this energy-saving construction structure for garden buildings are as follows: S1, first fix a vertical multi-sided center column at the center of the planned construction and installation position, and fix and install each column 300. This multi-sided center column is used for the positioning of the top of the prefabricated pavilion top module 200.

[0039] S2. Then, with the multi-sided 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 installed and clamped in place.

[0040] S3. Remove the multi-sided central column, and install and fix the pavilion tip 100, the water collecting pipe 400, and the eaves casing 500 correspondingly.

[0041] In another preferred embodiment, as Figure 7 shown, on the basis of the above embodiment, the ventilation duct 211 is provided with a constriction 2111, and the negative pressure channel 212 is opened at the constriction 2111. The constriction 2111 is integrally formed with the fusible embedded column by a mold, and no additional processing is required after autoclave curing, and the process cost is controllable.

[0042] The constriction 2111 in the ventilation duct 211 adopts a tapered - expanding streamline cross-section (such as a conical or arc-shaped constriction). When natural wind passes through the constriction 2111, the air flow velocity increases and the static pressure decreases, forming a local strong negative pressure area at the narrowest part (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 is connected to the water flow channel 241 of the water collecting port 240. The rainwater in the water collecting port 240 is directly sucked by using the negative pressure at the throat, and it is higher than the water collecting port 240 in position, avoiding the failure caused by the water collecting filling the negative pressure channel 212, and significantly and stably improving the drainage driving force.

[0043] The energy-saving construction structure of this garden building is modularly designed, which is convenient for processing, disassembly and installation. Therefore, it is convenient to move and change the installation position. Especially after installation, it can still be replaced, improving the adaptability. Correspondingly, a detachable and movable base is provided at the bottom of the column 300.

[0044] In summary, the energy-saving construction structure of this garden building includes a plurality of prefabricated pavilion roof modules 200 that are detachably connected. The top of the module is fixed to the upper connecting plate 110 through the pavilion tip 100, and the bottom is assembled with the column 300 through the positioning groove 260 and the connecting block 270, realizing rapid installation and mobility.

[0045] The pavilion roof module adopts autoclaved aerated concrete board, and the internal embedded fusible columns form the ventilation duct 211, the water flow channel 241 and the negative pressure channel 212 after autoclave curing. The kinetic energy of natural wind is utilized to improve the rainwater collection efficiency through the negative pressure effect. During construction, it is positioned by the central column, and after modular assembly, it is replaced with the pavilion tip 100 and the water collection system.

[0046] The present invention integrates modular prefabrication, wind - drainage linkage and lightweight environmental protection materials, solves the problems of long construction period and low rainwater collection efficiency of traditional pavilion buildings, and has both ecological benefits and construction convenience, and is applicable to the energy-saving transformation of garden landscapes.
