[0002] An air dome is a type of building that uses air pressure to support its structure. It is usually made of a special architectural membrane as its outer shell and is equipped with an intelligent operation control system to provide air pressure inside, allowing the main body of the building to be supported by the pressure difference between the inside and the outside. Its working principle is based on the compressibility of air and the pressure difference. Air is continuously filled into the space between the membrane and the ground or the foundation structure through equipment such as blowers, forming an air pressure higher than the external environment, thereby causing the membrane to generate outward tension, which is balanced with the internal air pressure, thereby supporting the entire dome structure, enabling it to maintain a stable shape and sufficient strength to resist external loads.

[0046] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0047] Embodiment 1: The present invention provides a basic construction structure of an air dome, including: a dome side support beam 110, a bracket assembly, a water delivery pile 150, a woven mesh 170 and a screw pile 160;

[0048] As attached Figure 1 To Attachment Figure 2 As shown: two groups of dome side support beams 110 are arranged in parallel, and the dome side support beams 110 include a first support beam 111 and a second support beam 112, and the first support beam 111 and the second support beam 112 are both "H"-shaped plate structures;

[0049] As attached Figure 1 and attached Figure 5 As shown: the bracket assembly is erected at both ends of the dome side support beam 110, which includes an extension beam 120, an inner membrane support beam 130 and an outer membrane support beam 140. The dome side support beam 110, the inner membrane support beam 130, the outer membrane support beam 140 and the extension beam 120 are all H-shaped beams. The portion corresponding to the central transverse reinforcement of the H-shaped steel is called the web, and the vertical reinforcements at both sides of the transverse reinforcement that are at right angles to the transverse reinforcement are called flanges. The lower portion centered on the horizontal rod is called the lower flange 111a, and the flange at the top is called the upper flange 111b. The beam of the "H"-shaped structure has good mechanical properties. Its web can withstand shear force, and the flange can effectively resist bending moment, thereby providing stable lateral support for the entire air dome.

[0050] As attached Figure 3 As shown: the water delivery pile 150 is in a "U"-shaped structure, and the first support beam 111 and the second support beam 112 are installed at both ends of the water delivery pile 150;

[0051] As attached Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the woven mesh 170 covers the dome side support beams 110 and the bracket assembly to form an air dome.

[0052] As attached Figure 3 and attached Figure 4 As shown: the spiral pile 160 includes a cylindrical pile 161, a spiral blade 162 and a locking piece 163; the spiral blade 162 is formed on the circumference of the cylindrical pile 161, the locking piece 163 is fixed at the end of the cylindrical pile 161, and the locking piece 163 is pressed onto one side of the dome side support beam 110. The spiral blade 162 facilitates the pile body to be screwed into the ground, thereby increasing the friction between the pile and the soil. The locking piece 163 is fixed at the end of the cylindrical pile 161 and pressed onto one side of the dome side support beam 110, thereby further fixing the dome side support beam to prevent it from being blown up by external forces such as wind.

[0053] Extension beams 120 are horizontally installed at both ends of the two groups of dome side support beams 110, and vertical outer membrane support beams 140 are installed between the two groups of extension beams 120. Two groups of inner membrane support beams 130 are vertically installed between the two groups of dome side support beams 110. The two groups of inner membrane support beams 130 are respectively located at both ends of the dome side support beams 110. A number of reinforcement lines 190 are fixedly connected between the two groups of inner membrane support beams 130. An engine room 201 is formed between the inner membrane support beams 130 and the outer membrane support beams 140, and an entrance 200 is provided at the outer membrane support beam 140.

[0054] A woven mesh fixing part 171 is installed on the inner surface of the first support beam 111 and the second support beam 112, and a plurality of hangers 181 are arrayed on the outer surface of the first support beam 111 and the second support beam 112. A metal wire 180 is pressed between two groups of symmetrically arranged woven mesh fixing parts 171, and a metal wire 180 is also connected between the two groups of symmetrically arranged hangers 181, and the woven mesh 170 covers the metal wire 180.

[0055] A plurality of reinforcing ribs 113 are installed between the first support beam 111 and the second support beam 112 .

[0056] A plurality of through holes 111c are provided between the first support beam 111, the second support beam 112 and the water delivery pile 150, and fixing bolts 111d and nuts 111e are installed at the through holes 111c;

[0057] In order to enhance the stability of the air dome, the dome side support beam 110 can be installed on the water delivery pile 150, i.e., the platform feather, to play a counterweight role. In this case, the weight of the water delivery pile 150 and its underground part, plus the weight of the water filled in the water delivery pile 150, will form a larger load, thereby ensuring that the air dome of the present invention can be stably supported even in strong winds.

[0058] At this time, in order to firmly fix the dome side support beam 110 on the water delivery pile 150, the lower flange 111a of the dome side support beam 110 needs to be placed on the water delivery pile 150 and fixedly connected by bolts 111d and nuts 111e.

[0059] The outer wall of the first support beam 111 and the second support beam 112 is threaded with a plurality of clamping bolts 172, and the position of the clamping bolts 172 is adapted to the braided mesh fixing piece 171; by screwing in the clamping bolts 172, the braided mesh fixing piece 171 can be closely fitted with the braided mesh 170. It is more ideal to fix the braided mesh 170 to the inner side of the upper flange 111b of the H-shaped steel beam; the braided mesh 170 is covered at the metal wire 180, and the braided mesh 170 is fixed to the dome side support beam 110 by the metal wire 180, so that the braided mesh 170 can be closely fitted on the support structure to form an airtight air dome, and by screwing in the clamping bolts 172, the braided mesh fixing piece 171 can be closely fitted with the braided mesh 170, further ensuring the fixing effect of the braided mesh.

[0060] Embodiment 2: The inner membrane support beam 130 and the outer membrane support beam 140 are preferably circular in shape. In the air dome structure, since it is significantly affected by wind force, a streamlined structure is adopted to minimize the influence of wind.

[0061] Therefore, it is ideal that the inner membrane support beam 130 supporting the inner membrane and the outer membrane support beam 140 supporting the outer membrane have a hemispherical or arc-shaped curvature; for the extension beam 120, its structure is used to support the outer membrane support beam 140 so as to construct a machine room 201 or an entrance 200 outside the inner membrane support beam 130, and it is also expected to have a hemispherical or arc-shaped curvature.

[0062] At this time, the radius of curvature of the inner membrane support beam 130 is greater than the circular diameter of the outer membrane support beam 140, because the outer membrane support beam 140, as a structure supporting the outer membrane, needs to form an inlet 200.

[0063] The woven net 170 is constructed by connecting two sets of inner membrane support beams 130 with reinforcing wires 190, which can effectively prevent the woven net 170 from sagging. When there is a power outage, a blower failure, or when the blowing stops when replacing the woven net 170, the internal pressure of the air film will decrease, and the woven net 170 may sag due to its own weight, thereby causing damage to the covered crops; to avoid such situations, whether it is a power outage or a failure such as strong wind, this structure is extremely critical to prevent the woven net 170 from sagging above the crops.

[0064] A pair of air film side support beams 110 are arranged at a predetermined interval, and the pair of dome side support beams 110 are connected by means of reinforcing ribs 113 and arranged in parallel; an extension beam 120 horizontal to the ground is connected to the two ends of each outer beam of a pair of dome side support beams 110, and the two ends of each inner beam in a pair of beams are connected to the inner membrane support beam 130 perpendicular to the ground, and then the outer membrane support beam 140 is connected to the two ends of the extension beam 120 and made perpendicular to the ground. This step is to ensure that the side support beam 110 is fixed by the screw pile 160 to prevent it from being blown up by external forces such as wind.

[0065] Embodiment 3: According to the planned position, the water delivery pile 150 is driven into the ground to ensure that its depth and verticality meet the design requirements. During the driving process, the depth and inclination of the pile body are monitored in real time, and timely adjustments are made if there are deviations.

[0066] The first support beam 111 and the second support beam 112 are butt-jointed with the two ends of the water delivery pile 150 through the through hole 111c, and the fixing bolts 111d and nuts 111e are installed and tightened with a torque wrench according to the specified torque to ensure a firm connection.

[0067] Reinforcing ribs 113 are installed between the first support beam 111 and the second support beam 112. The spacing between the reinforcing ribs is determined according to structural design calculations. The ribs are connected by welding to ensure uniform weld quality without defects such as pores and cracks.

[0068] Use measuring instruments (such as levels and theodolites) to accurately measure the parallelism and horizontality of the first support beam and the second support beam, and control the error within a very small range. If there is any deviation, correct it by adjusting bolts or placing shims under the beams.

[0069] The extension beams 120 are installed horizontally at both ends of the two sets of dome side support beams 110, and are connected by welding or high-strength bolts to ensure that the extension beams are tightly connected to the dome side support beams 110 and the levelness meets the requirements, and the levelness deviation does not exceed the specified value.

[0070] The outer membrane support beam 140 is vertically installed between the two groups of extension beams 120, and the outer membrane support beam 140 is lifted by a crane or other equipment. After adjusting the verticality, it is welded or bolted to the extension beam 120, and the verticality error is controlled within the design allowable range.

[0071] Two groups of inner membrane support beams 130 are vertically installed between the two groups of dome side support beams 110. The inner membrane support beams are respectively located at both ends of the dome side support beams. The same precise installation method is used to ensure the verticality of the inner membrane support beams and the firmness of the connection with the dome side support beams. The connection parts are reinforced to prevent loosening.

[0072] The braided mesh fixing parts 171 are installed on the inner surface of the first support beam 111 and the second support beam 112, and are fixed by rivets or bolts to ensure that the fixing parts are firmly installed and the spacing is uniform. The hanging parts 181 are installed on the outer surface, and the layout of the hanging parts is carried out according to the design requirements to ensure that the braided mesh can be evenly supported.

[0073] The metal wire 180 is connected between the symmetrically arranged woven mesh fixings 171 and the hangers 181 to form a support network of the metal wire 180. The tension of the metal wire is moderate to ensure sufficient support for the woven mesh without damaging the woven mesh or the fixings due to excessive tension.

[0074] The braided mesh 170 is covered on the metal wire 180, and gradually spread out from one end of the dome to cover the entire frame. The braided mesh should be laid flat without wrinkles or damage. Then the braided mesh 170 is fixed to the braided mesh fixing part 171 by the clamping bolt 172. The tightening degree of the clamping bolt 172 is gradually adjusted to ensure that the braided mesh is firmly fixed and fits tightly with the fixing part to avoid gaps that may cause air leakage.

[0075] A number of reinforcing wires 190 are fixedly connected between the two groups of inner membrane support beams 130. The reinforcing wires are made of high-strength materials, and the spacing between them is determined according to the span and stress conditions of the woven mesh. The connection method is firm and reliable to prevent the woven mesh from sagging.

[0076] An entrance 200 is provided at the outer membrane support beam 140, and the structural design of the entrance should facilitate the entry and exit of personnel and equipment while ensuring air tightness. Special sealing materials and connection methods are used to ensure that there is no air leakage at the entrance.

[0077] The machine room 201 is installed between the inner membrane support beam 130 and the outer membrane support beam 140. The frame of the machine room is firmly connected to the support beam. The walls and roof are installed with suitable building materials to ensure the sealing and heat insulation of the machine room, providing a good operating environment for the internal equipment.

[0078] After the dome side support beam 110 is installed, screw piles 160 are installed at appropriate positions on both sides thereof. The cylindrical pile 161 is screwed into the ground through the spiral blade 162. After reaching the designed depth, the locking piece 163 is fixed to the end of the cylindrical pile 161 and pressed onto one side of the dome side support beam 110, and is further fixed by bolts or welding to enhance the wind resistance of the entire structure.

[0079] After the installation is completed, the entire air dome is fully debugged. First, the inflation equipment is started to inflate the dome, the air pressure changes are monitored, and the air tightness of the woven mesh is checked to ensure that there is no obvious leakage under the specified air pressure.

[0080] Check whether each connection point is firm, including between beams, between beams and piles, between woven mesh and fixings, etc. If there is any looseness, reinforce it in time.

[0081] Simulated wind load and snow load tests are carried out to detect the stability and deformation of the structure by applying corresponding loads on the dome surface. According to the test results, necessary optimization and adjustments are made to the structure to ensure that the air dome can operate safely under various severe weather conditions.
