Description

Technical Field

[0001] This application belongs to the technical field of construction protection equipment, and in particular relates to a portable inflatable pit rainproof device. Background Technology

[0002] Currently, in construction, the main rain protection measures for foundation pits include five types: traditional canvas awnings, large mobile awnings, simple plastic sheeting, foundation pit support umbrella devices, and traditional inflatable airbag covers. All are used to mitigate the impact of rainfall on foundation pit construction. However, the following problems exist: ① Traditional canvas awnings require on-site steel structure support, which is time-consuming and labor-intensive to install, and is inconvenient to move and reuse quickly; ②Large mobile canopies are bulky, rely on heavy equipment for transportation, have poor flexibility, and are not suitable for small or scattered foundation pits; ③ The simple plastic sheet covering has the disadvantages of weak wind resistance and easy to be blown over, and poor light transmission, which affects the lighting and construction visibility in the foundation pit; ④ The foundation pit support umbrella device relies on the internal support structure of the foundation pit, which hinders the binding of steel bars and the pouring of concrete, and is inconvenient to disassemble and assemble. ⑤ Traditional inflatable airbag covers are used to seal the top of the foundation pit, which hinders concrete pouring and affects the construction progress. Summary of the Invention

[0003] In view of this, this application aims to propose a portable inflatable rain shelter for foundation pits to solve the problems of existing rain shelter measures for foundation pits being inconvenient to install, lacking flexibility, insufficient wind resistance and light transmission, and some devices hindering construction inside the foundation pit and affecting the construction progress.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: This application provides a portable inflatable pit rain shelter, comprising: The support frame consists of multiple interconnected rubber tubes and multiple rigid rubber rods fixedly connected to the bottom connection points of adjacent rubber tubes. The multiple rubber tubes are arranged in a preset arc trajectory to form a multi-faceted arc profile, and the rubber tubes are connected to an external inflation device. The multiple rigid rubber rods are cross-connected, and the rubber tubes and the rigid rubber rods work together to form an arc-shaped dome-shaped support frame. A waterproof tarpaulin is provided on the supporting frame, and two arc-shaped openings are provided on each side of the waterproof tarpaulin. The upper edge of the two arc-shaped openings is provided with a forward-leaning rainproof structure, and the size of the lower arc-shaped opening is larger than the size of the upper arc-shaped opening.

[0005] Furthermore, the forward-leaning rainproof structure located at the upper arc-shaped opening is a rigid rubber sheet, which is set on the waterproof tarpaulin.

[0006] Furthermore, the forward-tilting rainproof structure located at the lower arc-shaped opening is composed of two arc-shaped rigid rubber supports and a support rod disposed between the two rigid rubber supports; The two rigid rubber supports form a rainproof frame, a waterproof tarpaulin is provided between the two rigid rubber supports, and the two rigid rubber supports are hinged at the bottom corner of the arc-shaped opening. Support bases are pre-installed at the arc tops of the two rigid rubber supports, and the support rod is set between the two support bases.

[0007] Furthermore, the bottom of the rubber air tube is provided with an inflation / deflation port, which is connected to an inflation device for inflating or deflating the rubber air tube.

[0008] Furthermore, the waterproof tarpaulin is a PVC-coated polyester fiber duct-coated fabric.

[0009] Furthermore, a lifting ring is provided at the top intersection position of the rigid rubber rod.

[0010] Furthermore, a fixing ring is provided at the bottom corner edge of the support frame, and the anchor bolt passes through the fixing ring to fix the rainproof device to the ground.

[0011] Compared with the prior art, the portable inflatable pit rainproof device described in this application has the following advantages: (1) Portable and efficient: The structure is simple. The main body adopts an inflatable support structure. After deflation, the volume is greatly reduced, which is convenient for transportation and storage. Installation or disassembly can be completed within 3-5 minutes. It can solve the problems of insufficient professional construction personnel in foreign projects, lack of large auxiliary equipment in the field, wide distribution of small and scattered foundation pits and frequent site changes. In particular, it addresses the core pain points of frequent rainfall, inconvenient transportation and difficulty in equipment deployment in tropical rainforest areas.

[0012] (2) Multifunctional opening: The arc-shaped opening design ensures sufficient lighting in the foundation pit and effectively reduces wind resistance. At the same time, the large opening at the bottom supports the normal progress of concrete pouring and other processes.

[0013] (3) Stable and durable: The combination of rubber air pipes and support rods provides excellent structural stability. Combined with high-strength tarpaulin, it can withstand moderate to heavy rain and 5-6 level gusts.

[0014] (4) Good economic efficiency: It can be reused and does not require the construction and dismantling of heavy steel structures, which significantly reduces construction costs and manpower input. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.

[0019] Please see Figures 1 to 3 As shown, this embodiment provides a portable inflatable pit rain shelter, comprising: The support frame consists of multiple interconnected rubber tubes 1 and multiple rigid rubber rods 2 fixedly connected to the bottom connection of two adjacent rubber tubes 1. The multiple rubber tubes 1 are arranged in a preset arc trajectory to form a multi-faceted arc profile, and the rubber tubes 1 are connected to an external inflation device. The multiple rigid rubber rods 2 are cross-connected, and the rubber tubes 1 and rigid rubber rods 2 work together to form an arc-shaped dome-shaped support frame. The waterproof tarpaulin 3 is set on the support frame, and two arc-shaped openings are opened on each side of the waterproof tarpaulin 3. The upper edge of the two arc-shaped openings is provided with a forward-leaning rainproof structure, and the size of the lower arc-shaped opening is larger than the size of the upper arc-shaped opening.

[0020] Specifically, in this embodiment, the core support structure of the rainproof device uses a rubber air pipe 1 and two intersecting rigid rubber rods 2 at the top to form an arc-shaped dome support frame. The specific cooperation relationship is as follows: the rubber air pipe 1 serves as the main load-bearing component of the frame, and is arranged according to a preset arc trajectory to form the four-sided arc contour of the dome. The connection position of the two rubber pipes is fixedly connected to the rigid rubber rods 2. The rigidity of the rigid rubber rods 2 is used to compensate for the slight deformation of the rubber air pipe 1 after inflation, while enhancing the overall stability of the support frame and preventing the dome from collapsing or deforming due to wind or external pressure. Together, they form an arc-shaped dome support body that is adapted to the size of the foundation pit.

[0021] The outer side of the supporting frame is fully covered with high-strength waterproof and wear-resistant tarpaulin. The tarpaulin material is made of PVC-coated polyester fiber cloth or knife-coated cloth, which can withstand moderate to heavy rain and gusts of wind at level 5-6.

[0022] The dome-shaped support frame used in this embodiment has two arc-shaped openings of different sizes on each side. Both arc-shaped openings have forward-leaning rainproof structures. The arc-shaped dome structure combined with the forward-leaning rainproof design can effectively reduce the resistance of strong winds in the field, while preventing rainwater from dripping along the edge of the rainproof cover into the foundation pit. This significantly improves the wind and rain resistance of the device in tropical rainy climates with frequent sudden strong winds abroad, ensuring construction quality and progress. The arc-shaped openings with light transmission can ensure clear visibility for construction inside the foundation pit, eliminating the need for additional lighting equipment. This is suitable for construction scenarios in the field abroad without fixed power supply. Furthermore, the large opening size at the bottom allows the pouring chute to pass directly through without interfering with normal operations such as rebar tying and concrete pouring inside the foundation pit.

[0023] It should be noted that this embodiment uses four rubber air tubes 1 and two hard rubber rods 2 as an example. This embodiment does not specifically limit the number of rubber air tubes 1 and hard rubber rods 2. They can be flexibly set according to the actual application scenario. Further details will not be elaborated here.

[0024] The rain shelter device described in this embodiment addresses the problems of insufficient professional construction personnel, lack of large auxiliary equipment in field sites, and the widespread distribution and frequent relocation of small and dispersed foundation pits in overseas projects. It is particularly relevant to the core pain points of frequent rainfall, inconvenient transportation, and difficulty in equipment deployment in tropical rainforest areas. The device uses rubber air pipes 1 and rigid rubber rods 2 to form a support frame, eliminating the need for on-site steel structure supports and reliance on construction equipment. This significantly reduces the labor intensity of construction personnel and enables rapid deployment and dismantling of the device. Quantitatively, it can be completed by two people, with inflation deployment time ≤ 5 minutes and deflation dismantling time ≤ 3 minutes. Compared with traditional canvas rain shelters, it greatly improves the construction efficiency of foundation pit rain shelter operations and is suitable for the construction needs of overseas projects with tight schedules and high labor costs.

[0025] In some implementations, such as Figure 1 and Figure 3 As shown, the forward-leaning rainproof structure located at the upper arc-shaped opening is a rigid rubber plate 4, which is set on the waterproof tarpaulin 3. The forward-tilting rainproof structure located at the lower arc-shaped opening consists of two arc-shaped rigid rubber supports 5 and a support rod 7 set between the two rigid rubber supports 5. Among them, two rigid rubber supports 5 form a rainproof frame, a waterproof tarpaulin 3 is provided between the two rigid rubber supports 5, and the two rigid rubber supports 5 are hinged at the bottom corner of the arc-shaped opening. Support bases 6 are pre-installed at the arc tops of the two rigid rubber supports 5 respectively, and support rods 7 are set between the two support bases 6.

[0026] Specifically, in this embodiment, the forward-leaning structure at the upper small arc-shaped opening is a rigid rubber plate 4, which opens automatically as the tarpaulin is stretched after the rainproof device is inflated; the forward-leaning rainproof structure at the lower large arc-shaped opening uses rigid rubber supports 5 at the arc-shaped edge and the connection with the main rainproof cloth. The two rigid rubber supports 5 are hinged together, and the top of the rigid rubber supports 5 is equipped with a support base 6. The support base 6 has an insertion groove, and the opening can be fixed after the support rod 7 is inserted.

[0027] In some implementations, such as Figure 2 As shown, the bottom of the rubber air tube 1 is provided with an inflation / deflation port 10, which is connected to an inflation device (not shown in the attached figure) for inflating or deflating the rubber air tube 1.

[0028] Specifically, in this embodiment, the inflation / deflation port 10 is connected to the gas cylinder via a connecting pipe. By opening the gas cylinder valve, the rubber air pipe 1 can be inflated. The device is portable and easy to move. After deflation and folding, it can be directly placed in the back of a pickup truck, facilitating rapid relocation between dispersed foundation pits. Its practicality and economy are significantly better than traditional rain protection equipment.

[0029] In some implementations, such as Figure 1 As shown, a lifting ring 8 is provided at the top intersection of the rigid rubber rod 2. The lifting ring 8 is hooked by a hoisting device to facilitate the transfer of the device.

[0030] Furthermore, such as Figure 1 As shown, a fixing ring 9 is provided at the bottom corner edge of the support frame. Anchor bolts pass through the fixing ring 9 to fix the rainproof device to the ground, thus completing the reinforcement.

[0031] After use, the rainproof device can be deflated and folded. It is made of lightweight material and can be carried by two people. It is reusable. Through the coordinated design of the opening and the reinforcement structure, it does not interfere with the normal operation of the foundation pit such as steel bar binding and concrete pouring. It effectively solves the core pain point of sudden rainfall in the field foundation pit construction causing water accumulation in the foundation pit, contaminating the concrete material and affecting the construction progress.

[0032] When implementing this rainproof device, the following operating steps are followed: 1. Preparation: Transport the foldable rain cover to the side of the foundation pit.

[0033] 2. Inflation and Forming: Connect the gas cylinder to the inflation port of the rubber air hose 1, and slowly inflate to the preset pressure (e.g., 0.2-0.3MPa) to expand the support frame and form an arc-shaped dome support frame.

[0034] 3. Auxiliary support: Screw the support rod 7 into the forward-tilting rainproof structure with the lower opening.

[0035] 4. Positioning and Use: The assembled rain cover is hoisted or pushed to the top of the foundation pit, its position is adjusted so that it completely covers the foundation pit, and anchor bolts are inserted for fixation; through the opening at the bottom, construction operations such as chute pouring can be carried out as usual.

[0036] 5. Storage and Transfer: After use, pull out the anchor bolts, unscrew the support rod 7, release the gas in the rubber air tube 1, and after the frame has fully retracted, fold all parts for storage for the next use.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
