[0051] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail through specific embodiments below.

[0052] As Figures 1-6 Shown, an arched tennis hall includes a main court frame and a ceiling covering the main court frame. Among them, the main court frame includes a plurality of arc-shaped and upwardly arched arc-shaped support bodies 1 and a plurality of frame connecting rods 2. The arc-shaped support bodies 1 are arranged side by side along the axis direction of the arc-shaped support bodies 1, and the frame connecting rods 2 are parallel to the axis of the arc-shaped support bodies 1 and are connected to each arc-shaped support body 1.

[0053] After adopting the above structure, the present invention relates to an arched tennis hall. The plurality of arc-shaped support bodies 1 are connected to each other through the frame connecting rods 2 to form an arched main court frame. With the arched structure, when encountering strong wind and heavy rain weather, the main court frame can disperse the wind pressure received on the side to both sides of the bottom end of the arc-shaped support body 1, thereby enhancing the structural stability of the main court frame, and the ceiling can play a rain shielding effect. In addition, when encountering an earthquake, the arched structure of the main court frame itself is stable and not easily deformed, which can effectively prevent the main court frame from collapsing.

[0054] Compared with the prior art, the main court frame of the present invention is composed of a plurality of arc-shaped support bodies 1 connected to each other, and the outer shape is in an arched structure. It has a stable structure itself, is light in weight and large in bearing capacity, can withstand super typhoons and earthquakes, and will never collapse. In addition, the arched structure can scientifically disperse the bearing capacity of the ground, realize a column-free structure, and reduce the occupation of the venue area in the hall.

[0055] Preferably, the arc-shaped support body 1 includes two arc-shaped support single frames 11 arranged along the axis direction of the arc-shaped support body 1. The arc-shaped support single frames 11 are connected by single frame connecting rods. Specifically, in this embodiment, the single frame connecting rod is the frame connecting rod 2. By adopting the above structure, the outer shape structure of the arc-shaped support body 1 is in the shape of an arc-shaped column, and the cross-section of the arc-shaped support body 1 is in a rectangular structure. This structure has better stability and load-bearing capacity, thereby improving the compressive resistance of the arc-shaped support body 1 and being less likely to deform and collapse in structure.

[0056] Preferably, the arc-shaped support single frame 11 includes an outer arc-shaped rod 111 arranged on the outer circle, an inner arc-shaped rod 112 arranged on the inner circle, and a plurality of arc-shaped frame connecting rods arranged between the outer arc-shaped rod 111 and the inner arc-shaped rod 112. The arc-shaped frame connecting rods are used to connect and support the outer arc-shaped rod 111 and the inner arc-shaped rod 112. The outer arc-shaped rod 111 and the inner arc-shaped rod 112 provide support forces for the arc-shaped support single frame 11 simultaneously from the outside and the inside, enhancing the load-bearing capacity of the arc-shaped support single frame 11. Moreover, the outer arc-shaped rod 111 and the inner arc-shaped rod 112 are supported by the arc-shaped frame connecting rods, so that after the outer arc-shaped rod 111 and the inner arc-shaped rod 112 are subjected to external pressure, they can transmit and disperse the pressure to each other, further improving the compressive strength of the structure.

[0057] Preferably, due to the large area and high height of the tennis hall, the lengths of the outer arc-shaped rod 111 and the inner arc-shaped rod 112 are relatively long and the radian is relatively large. When a single pipe is bent and processed, it is easy to break, resulting in difficulties in processing and forming the outer arc-shaped rod 111 and the inner arc-shaped rod 112. In order to facilitate the processing and forming of the outer arc-shaped rod 111 and the inner arc-shaped rod 112, the outer arc-shaped rod 111 is composed of a plurality of outer arc-shaped rod single segments 1111 connected together, and the inner arc-shaped rod 112 is composed of a plurality of inner arc-shaped rod single segments 1121 connected together.

[0058] Preferably, adjacent outer arc-shaped rod single segments 1111 are connected together by an outer connecting sleeve 1112; adjacent inner arc-shaped rod single segments 1121 are connected together by an inner connecting sleeve 1122. With the above structure, the processing and forming of the outer arc-shaped rod 111 and the inner arc-shaped rod 112 are more convenient, and the connection is more firm.

[0059] Preferably, as a connection process for the outer connecting sleeve 1112 and the inner connecting sleeve 1122, during installation and connection, first insert both sides of the outer connecting sleeve 1112 into the outer arc-shaped rod single segment 1111, and insert both sides of the inner connecting sleeve 1122 into the inner arc-shaped rod single segment 1121. Then, weld the side surfaces of both ends of the outer connecting sleeve 1112 to the outer surfaces of the two side outer arc-shaped rod single segments 1111 respectively, and weld the side surfaces of both ends of the inner connecting sleeve 1122 to the outer surfaces of the two side inner arc-shaped rod single segments 1121 respectively.

[0060] Preferably, in order to further improve the connection strength between the outer arc-shaped rod 111 and the inner arc-shaped rod 112, the connection ends of two adjacent outer arc-shaped rod monomer segments are welded together, and the connection ends of two adjacent inner arc-shaped rod monomer segments are welded together. Specifically, when connecting the outer connection sleeve 1112, first, one side of the outer arc-shaped rod monomer segment 1111 is completely passed through the outer connection sleeve 1112 and welded and fixed with the outer arc-shaped rod monomer segment 1111 on the other side. Then, the outer connection sleeve 1112 is moved so that the welding points of the outer arc-shaped rod monomer segments 1111 on both sides extend into the outer connection sleeve 1112. After that, the two side surfaces of the outer connection sleeve 1112 are further welded to the outer side surfaces of the outer arc-shaped rod monomer segments 1111 on both sides; when connecting the inner connection sleeve 1122, first, one side of the inner arc-shaped rod monomer segment 1121 is completely passed through the inner connection sleeve 1122 and welded and fixed with the inner arc-shaped rod monomer segment 1121 on the other side. Then, the inner connection sleeve 1122 is moved so that the welding points of the inner arc-shaped rod monomer segments 1121 on both sides extend into the inner connection sleeve 1122. After that, the two side surfaces of the inner connection sleeve 1122 are further welded to the outer side surfaces of the inner arc-shaped rod monomer segments 1121 on both sides.

[0061] Preferably, the arc-shaped frame connecting rod includes alternately arranged first arc-shaped frame connecting rods 113 and second arc-shaped frame connecting rods 114. The first arc-shaped frame connecting rod 113 is vertically connected between the inner arc-shaped rod 112 and the outer arc-shaped rod 111, and can vertically transfer the pressure received by the outer arc-shaped rod 111 to the inner arc-shaped rod 112 along the first arc-shaped frame connecting rod 113. The first arc-shaped frame connecting rod 113 includes a first inner connection end connected to the inner arc-shaped rod 112 and a first outer connection end connected to the outer arc-shaped rod 111; the second arc-shaped frame connecting rod 114 includes a first inclined rod 1141 and a second inclined rod 1142. The first inclined rod 1141 gradually inclines towards the outer end direction of the inner arc-shaped rod from the inner arc-shaped rod to the outer arc-shaped rod direction. The first inclined rod 1141 includes a second inner connection end connected to the inner arc-shaped rod 112 and a second outer connection end connected to the outer arc-shaped rod 111. The second inclined rod 1142 gradually inclines towards the middle direction of the inner arc-shaped rod from the inner arc-shaped rod to the outer arc-shaped rod direction. The second inclined rod 1142 includes a third inner connection end connected to the inner arc-shaped rod 112 and a third outer connection end connected to the outer arc-shaped rod 111. The adjacent first inner connection end, second inner connection end, and third inner connection end are connected to each other, and the adjacent first outer connection end, second outer connection end, and third outer connection end are connected to each other. This structure makes the connection structure between the first inclined rod 1141 and the second inclined rod 1142 in a V-shaped structure. The second arc-shaped frame connecting rod 114 can transfer the pressure received by the outer arc-shaped rod 111 downward to two stress points of the inner arc-shaped rod 112, playing a role in dispersing the pressure. At the same time, a right triangle support structure is formed between the first arc-shaped frame connecting rod 113 and the second arc-shaped frame connecting rod 114, having better support stability.

[0062] Preferably, the centers of the outer arc-shaped rod 111 and the inner arc-shaped rod 112 coincide. This structure makes the distance between the outer arc-shaped rod 111 and the inner arc-shaped rod 112 equal everywhere, so that the length of each first arc-shaped frame connecting rod 113 is equal, and the force on the first arc-shaped frame connecting rods 113 is more uniform, further improving the structural stability.

[0063] Preferably, the frame connecting rod 2 includes an outer frame connecting rod 21 connected to the outer side surface of the arc-shaped support frame 1 and an inner frame connecting rod 22 connected to the inner side of the arc-shaped support frame 1. This structure makes the overall connection structure more firm by fixedly connecting the inner and outer surfaces of the arc-shaped support frame 1 at the same time, enhancing the stability of the main frame of the court.

[0064] Preferably, the arc-shaped support frame 1 is made of stainless steel material. According to the bearing capacity of different parts, stainless steel materials with different thicknesses and properties are selected to save consumables and thus save the construction cost. At the same time, the stainless steel material has good corrosion and rust prevention performance, improving the service life of the tennis hall and reducing a large amount of maintenance and repair costs.

[0065] Preferably, the arc-shaped support frame 1 is also provided with a steel wire rope 12. Let the highest point in the vertical direction of the inner arc-shaped rod 112 be the midpoint. The inner arc-shaped rod 112 includes a first arc segment 1123 and a second arc segment 1124 separated by the midpoint. The first arc segment 1123 and the second arc segment 1124 arch from both sides of the inner arc-shaped rod towards the midpoint direction respectively. The two ends of the steel wire rope 12 are respectively connected to the inner sides of the first arc segment 1123 and the second arc segment 1124. The steel wire rope 12 exerts an inward pulling force on both sides of the inner arc-shaped rod 112, making the inner arc-shaped rod 112 not easily expand and deform outward, further increasing the structural strength of the inner arc-shaped rod 112.

[0066] Preferably, in order to enable the tennis hall to be used normally at night, a lighting lamp for providing lighting for the tennis court is hung on the steel wire rope 12.

[0067] Preferably, each bottom of the arc-shaped support frame 1 is further provided with a vertically arranged support column 3. The support column 3 provides a supporting force for the arc-shaped support frame 1 in the vertical direction, further enhancing the structural stability of the arc-shaped support frame 1.

[0068] Preferably, a fence 4 is provided between the support columns 3. The fence 4 can isolate the tennis court from the outside world, prevent foreign objects from falling into the tennis court, play a role in protecting the tennis court, and keep the tennis court clean and tidy.

[0069] Preferably, the support column 3 includes a vertical support rod 31. The upper end of the vertical support rod 31 is connected to the inner arc rod 112. The upper ends of adjacent vertical support rods 31 are connected by an inner frame connecting rod 22. The lower ends of adjacent vertical support rods 31 are connected by a transverse connecting bottom rod 32. A rectangular support structure is formed among the adjacent vertical support rods 31, the connected inner frame connecting rod 22, and the transverse connecting bottom rod 32, further enhancing the support stability of the support rod.

[0070] Preferably, a connecting foot 5 is further provided at the bottom of the arc support frame 1. The connecting foot 5 is used to fixedly connect the bottom of the arc support frame 1 to the ground. Specifically, it can be screwed to the ground. At the same time, the connecting foot 5 increases the contact area between the arc support frame 1 and the ground, making the arc support frame 1 stand more stably.

[0071] Preferably, the connecting foot 5 includes a horizontal connecting rod 51. One end of the horizontal connecting rod 51 is connected to the bottom end of the outer arc rod 111, and the other end is connected to the lower end of the vertical support rod 31. The bottom end of the inner arc rod 112 is connected between the two ends of the horizontal connecting rod 51. A support structure similar to a right triangle is formed among the horizontal connecting rod 51, the connected vertical support rod 31, and the inner arc rod 112, further enhancing the support stability of the arc support frame 1.

[0072] Preferably, a windproof ceiling 61 is covered on the arc support frame 1. A skylight opening 611 is opened on the windproof ceiling 61. A skylight ceiling 62 for blocking the skylight opening 611 is provided above the skylight opening 611. Since there is a height difference between the skylight ceiling 62 and the windproof ceiling 61, two ventilation openings 63 are formed between the two sides of the skylight ceiling 62 and the windproof ceiling 61. After adopting the above structure, according to Bernoulli's principle, the indoor air flow rate inside the ventilation opening 63 is slower and the pressure is larger, while the outdoor air flow rate outside the ventilation opening 63 is faster and the pressure is smaller. At this time, the negative pressure generated inside and outside the ventilation opening 63 will automatically extract the air in the tennis hall outward through the ventilation opening 63, achieving the effect of automatic ventilation and air exchange. There is no need to install air conditioners, saving electricity costs. And it keeps the air in the tennis hall fresh and smooth, warm in winter and cool in summer, making the exercise more comfortable.

[0073] Preferably, a plurality of skylight support frames 71 are further provided at the top of the arc support frame 1. The skylight support frames 71 extend upward and pass through the skylight opening 611.

[0074] Preferably, a skylight arc rod 72 is provided at the upper end of the skylight support frame. The skylight arc rod 72 is used to support the skylight ceiling 62 to prevent rainwater from leaking into the tennis hall through the skylight opening 611 on rainy days.

[0075] Preferably, the skylight arc rod 72 is arranged above the outer arc rod 111. With this structure, when it rains, the rain first falls on the skylight ceiling 62 supported by the skylight arc rod 72, and then the rain slides down along both sides of the skylight ceiling 62 to the windproof ceiling 61 supported by the outer arc rod 111, and finally slides down along both sides of the windproof ceiling 61, effectively preventing rainwater from flowing into the skylight opening 611 and further enhancing the rainproof function of the tennis hall.

[0076] Preferably, the ventilation opening 63 is provided with a plurality of intelligent remotely controlled louvers 8, and the louvers 8 control the opening or closing of the ventilation opening 63. For example, when the weather is relatively cold in winter, the louvers 8 can be closed to reduce the inflow of cold outdoor air and maintain the indoor temperature.

[0077] More preferably, the louver 8 includes a window frame 81, a plurality of louver blades 82 arranged in the window frame 81, and a driving mechanism 83 for driving the rotation of the louver blades 82. After adopting the above structure, the louver 8 is controlled to open or close by the driving mechanism 83.

[0078] More preferably, the driving mechanism 83 includes a transmission strip 831, a connecting piece 832, and a driving motor 833. The transmission strip 831 is arranged on the left and right sides of the window frame 81. The connecting piece 832 is connected to both side surfaces of the louver blade 82, and one end of the connecting piece 832 is pivotally connected to the window frame 81, and the other end is pivotally connected to the transmission strip 831. The driving motor 833 is connected to the transmission strip 831 and drives the transmission strip 831 to move vertically up and down. When the transmission strip 831 moves vertically, it drives the connecting piece 832 to rotate relative to the window frame 81, thereby driving the louver blade 82 to rotate relative to the window frame 81 to open or close the louver 8.

[0079] More preferably, a tooth row is provided on the transmission strip 831, and a gear 834 meshing with the tooth row is provided at the output end of the driving motor 833. The meshing drive of the tooth row and the gear 834 makes the up and down movement of the transmission strip 831 smoother.

[0080] More preferably, it further includes a control switch for remotely controlling the driving motor, which is convenient for users to remotely operate the control switch on the ground to open or close the louver 8.

[0081] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
