Description

Technical Field

[0001] This invention relates to the field of dust suppression spraying technology for high-rise buildings, and in particular to a safety net support system for dust suppression spraying in high-rise buildings using hinged fasteners. Background Technology

[0002] Traditional safety nets are erected using steel pipes and fasteners. When erecting and binding the safety nets, workers are working at height, resulting in a high risk factor. The structure is also unstable and prone to falling off under heavy wind loads, posing a significant danger.

[0003] According to green construction requirements, dust suppression spraying covers the entire site, requiring the installation of spraying facilities on the exterior facade of the building. However, the installation of safety nets on the exterior facade reduces the dust suppression effect.

[0004] This invention designs a device that integrates a safety net support and a sprinkler system, enabling convenient, quick, and safe installation and removal of the safety net. It uses a retractable horizontal support system with a retractable support structure via a pull rope, facilitating the removal of fallen objects from the safety net and the maintenance of the sprinkler system. Furthermore, it uses longitudinal horizontal support steel pipes as dust suppression pipes, saving materials while expanding the dust suppression range and meeting the requirements of green construction. Summary of the Invention

The fixed end of the horizontal support is fixed to the external upright. A sprinkler branch pipe is installed between two adjacent diagonal braces. One end of the sprinkler branch pipe is connected to the external upright via a hinged coupler, and the other end is connected to the end of the horizontal support. Safety nets are installed along the horizontal supports. The sprinkler pipes are connected to the end of the horizontal support, the diagonal braces, and the sprinkler branch pipes via T-shaped connectors.

[0010] Assemble the first section of diagonal brace and multiple standard sections of diagonal brace according to the design length. The first section of diagonal brace and the standard sections of diagonal brace are connected by a diagonal brace connecting sleeve. One end of the diagonal brace connecting lug is connected to the first section of diagonal brace, and the other end is connected to the hinge fastener.

[0011] Furthermore, the horizontal support of the present invention includes a horizontal support frame and a pull rope. The horizontal support frame is a scissor-type telescopic structure, and the pull rope passes through the horizontal support frame and is connected to both ends of the horizontal support frame.

[0012] Furthermore, the sprinkler branch pipe of the present invention includes a sprinkler branch pipe connecting lug, a first section of sprinkler branch pipe, a bidirectional threaded joint, a standard section of sprinkler branch pipe, and a sprinkler branch pipe connector; wherein:

[0013] The first section of the spray branch pipe is connected to the standard section of the spray branch pipe via a two-way threaded connector. The standard section of the spray branch pipe and the spray pipe are connected using a two-way threaded connector. The first section of the spray branch pipe is equipped with a spray branch pipe connecting lug and a spray branch pipe connector. The main spray pipe is connected to the spray branch pipe connector.

[0014] Furthermore, the spray pipe of the present invention is also provided with a connection hole; the atomizing spray head is installed on the spray pipe and sealed with sealant.

[0015] Furthermore, the hinged fastener of the present invention includes a connecting plate, a pin, and a latch, wherein:

[0016] The fastener is connected to the horizontal support by a pin, and the pin passes through the pin hole on the plug to fix the plug.

[0017] Furthermore, the T-shaped connector of the present invention includes a spray pipe sleeve, a diagonal brace sleeve, a fastening bolt, a connector pin, and a connector insert, wherein:

[0018] Pass the spray pipe through the spray pipe sleeve, connect the spray pipe to the diagonal brace, adjust the fastening bolts so that the gap between the fastening bolts and the spray pipe is less than 1mm but not tightened, so that the T-shaped connector can rotate freely around the spray pipe; insert the end of the diagonal brace into the diagonal brace sleeve, and connect the diagonal brace and the T-shaped connector through the connector plug, and pass the connector pin through the pin hole on the connector plug to fix the plug plug connector.

[0019] This invention provides a construction method for a high-rise building sprinkler dust suppression safety net support system using hinged fasteners, comprising the following steps:

[0020] Step 1: Fabricate the support system and sprinkler system in the factory according to the drawings;

[0021] Step 2: Erect scaffolding according to the external scaffolding plan. When the height of the external scaffolding reaches the requirement for setting up safety nets, begin to erect the supports for the safety nets.

[0022] Step 3: Install the atomizing spray head onto the spray pipe and seal it with sealant; use a two-way threaded connector to connect the first section of the spray branch pipe to the standard section of the spray branch pipe; determine the overhang width of the safety net according to the fall radius, thereby determining the length of the spray branch pipe and the diagonal brace; assemble the standard section according to the required length; connect the standard section of the spray branch pipe to the spray pipe using a two-way threaded connector.

[0023] Step 4: Determine the overhang width of the safety net based on the fall radius, and thus determine the length of the diagonal brace. Assemble the first section of the diagonal brace and the standard section of the diagonal brace according to the required length, and connect them using the diagonal brace connecting sleeve. Pass the sprinkler pipe through the sprinkler pipe sleeve, connect the sprinkler pipe and the diagonal brace, and adjust the fastening bolts so that the gap between the fastening bolts and the sprinkler pipe is less than 1mm but not tightened, so that the T-shaped connector can rotate freely around the sprinkler pipe.

[0024] Step 5: Insert the diagonal brace sleeve into the end of the diagonal brace. Connect the diagonal brace and the T-shaped connector through the connector bolt. Pass the connector pin through the pin hole on the connector bolt to fix the bolt.

[0025] Step 6: Install hinged couplers on the outer uprights of the scaffold. The couplers are connected to the diagonal braces and sprinkler branches through bolts to form hinges. The pins are passed through the pin holes on the bolts to fix them in place.

[0026] Step 7: Repeat step 5 to install and connect the sprinkler pipe to the horizontal support; install safety nets on the sprinkler pipes and horizontal support, and after the safety nets are securely tied, install hinged couplers on the outer uprights of the scaffold. The hinged couplers are connected to the horizontal support by pins to form a hinge; the pins are passed through the pin holes on the screed to fix the screed.

[0027] Step 8: Connect the sprinkler water to the main sprinkler pipe through the sprinkler branch pipe joint; complete the installation of the safety net support system and the sprinkler system;

[0028] Step 9: Start dust monitoring. Based on the dust monitoring feedback, control the spray water pump. After the pump is turned on, the water flows through the main spray pipe into the branch pipe, and then through the bidirectional threaded joint connecting the branch pipe and the spray pipe into the spray pipe. The water then forms an atomized spray effect through the atomizing spray head.

[0029] Step 10: When there are falling objects on the safety net, pull out the limit pin on the horizontal support, retract the rope, and retract the horizontal support to retrieve the entire support system. Clear the objects from the safety net. When dismantling the scaffold, disconnect the sprinkler branch pipe joint from the sprinkler main pipe and retrieve the entire support system. Remove the safety net and horizontal support, then pull out the pin connecting the diagonal brace to the outer upright of the scaffold to complete the dismantling of the support system and sprinkler system.

[0030] The beneficial effects of this invention are:

[0031] (1) A telescopic horizontal support is adopted, and the steel pipes are connected by hinges. This can provide horizontal support for the support structure and also pull the support structure by pulling ropes. Construction personnel can complete the assembly of the support system and the installation of the safety net inside the floor, avoiding high-altitude work for personnel during the installation of the safety net. It can reduce the damage of typhoons and other severe weather, and facilitate the cleaning of objects falling from the dense mesh net, thus eliminating safety hazards.

[0032] (2) The diagonal bracing and spray branch pipe adopt a modular design (each length is 1.0m), which can be assembled according to the required length. The diagonal bracing is assembled using a connecting sleeve, and the spray pipe and spray branch pipe are connected by a two-way threaded internal connector, which facilitates installation and disassembly and ensures the airtightness of the spray pipe.

[0033] (3) Use hinged fasteners to enable safe and quick installation and removal of the inclined support steel pipe.

[0034] (4) T-shaped connectors are used to connect the support pipes and the spray pipes, which solves the problem of fixing the diagonal brace, horizontal support and spray pipe and realizing the rotation of the support around the spray pipe.

[0035] (5) Combine the dust suppression spray system with the safety net support system to improve dust suppression efficiency.

[0036] (6) Use longitudinal horizontal support steel pipes as spray water channels and use floor construction water for dust suppression to reduce material usage and save water resources.

[0037] (7) The device realizes the tool-based and modular assembly of safety nets, which standardizes the construction of safety nets and improves construction safety and speed. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0047] like Figures 1-6 As shown, the high-rise building dust suppression safety net support system using hinged fasteners in this embodiment of the invention consists of two parts: the first part is the safety net support system as support; the second part is the spray system.

[0048] The first part of the support system includes scaffold external uprights 1, scaffold horizontal bars 2, diagonal braces 3, retractable horizontal supports 4, safety nets 5, hinged fasteners 8, and T-shaped connectors 9; the second part of the sprinkler system includes sprinkler branch pipes 6, sprinkler pipes 7, atomizing sprinkler heads 7-1, and sprinkler main pipes 10.

[0049] Safety netting supports for high-rise buildings are installed on the building facade, with one net every six floors, attached to the external scaffolding. Their primary function is to prevent people and objects from falling, thus avoiding or mitigating injuries from falls and impacts. Among them:

[0050] The scaffolding external uprights 1 and scaffolding horizontal bars 2 are interconnected. One end of the diagonal brace 3 is connected to the scaffolding external upright 1 through a hinged coupler 8, and the other end is connected to the end of the horizontal support 4. The fixed end of the horizontal support 4 is fixed to the scaffolding external upright 1. A sprinkler branch pipe 6 is installed between two adjacent diagonal braces 3. One end of the sprinkler branch pipe 6 is connected to the scaffolding external upright 1 through a hinged coupler 8, and the other end is connected to the end of the horizontal support 4. The safety net 5 is installed along the horizontal support 4. The sprinkler pipe 7 is connected to the end of the horizontal support 4, the diagonal brace 3, and the sprinkler branch pipe 6 through a T-shaped connector 9. A misting sprinkler head 7-1 is installed on the sprinkler pipe 7 at regular intervals. The main sprinkler pipe 10 is connected to the sprinkler branch pipe 6.

[0051] The spray water pump is controlled by dust monitoring facilities. When dust levels exceed the specified values, the pump is activated. Spray water flows from the main spray pipe through the branch pipe connector, then enters the spray pipe via a two-way threaded connector, and is sprayed out through the atomizing spray heads to achieve dust suppression. Because a support system is used to support the spray pipes at a relatively high height, and the atomizing spray heads are lower than the safety net, the safety net does not affect the dust suppression effect, thus improving the dust suppression efficiency. Simultaneously, it saves water resources and reduces the use of support materials.

[0052] The diagonal brace 3 includes a diagonal brace connecting lug 3-1, a first diagonal brace section 3-2, a diagonal brace connecting sleeve 3-3, and a diagonal brace standard section 3-4; wherein:

[0053] Assemble the first section of diagonal brace 3-2 and the multi-section standard diagonal brace 3-4 according to the design length.

One end of the diagonal brace connecting lug 3-1 is connected to the first section of diagonal brace 3-2, and the other end is connected to the hinge fastener 8.

[0054] The horizontal support 4 includes a horizontal support frame 4-2 and a pull rope 4-1. The horizontal support frame 4-2 is a scissor-type telescopic structure, and the pull rope 4-1 passes through the horizontal support frame 4-2 and is connected to both ends of the horizontal support frame 4-2.

[0055] The sprinkler branch pipe 6 includes a sprinkler branch pipe connecting lug 6-1, a first section of sprinkler branch pipe 6-2, a two-way threaded joint 6-3, a standard section of sprinkler branch pipe 6-4, and a sprinkler branch pipe connector 6-5; wherein:

[0056] The first section of the spray branch pipe 6-2 is connected to the standard section of the spray branch pipe 6-4 via a two-way threaded connector 6-3. The standard section of the spray branch pipe 6-4 is connected to the spray pipe 7 via a two-way threaded connector 6-3.

[0057] The spray pipe 7 is also provided with a connection hole 7-2; the atomizing spray head 7-1 is installed on the spray pipe 7 and sealed with sealant.

[0058] The hinged fastener 8 includes a connecting plate 8-1, a pin 8-2, and a latch 8-3, wherein:

[0059] Fastener 8 is connected to horizontal support 4 by pin 8-2, and pin 8-3 passes through the pin hole on fastener 8-2 to fix fastener 8-2.

[0060] The T-shaped connector 9 includes a spray pipe sleeve 9-1, a diagonal brace sleeve 9-2, a fastening bolt 9-3, a connector pin 9-4, and a connector insert 9-5, wherein:

[0062] The construction method of the high-rise building sprinkler dust suppression safety net support system using hinged fasteners according to an embodiment of the present invention includes the following steps:

[0063] Step 1: Fabricate the support system and sprinkler system in the factory according to the drawings;

[0064] Step 2: Erect scaffolding according to the external scaffolding plan. When the height of the external scaffolding reaches the requirement for setting up safety net 5, start erecting the support for safety net 5.

[0065] Step 3: Install the atomizing spray head 7-1 onto the spray pipe 7 and seal it with sealant; use a two-way threaded connector 6-3 to connect the first section of the spray branch pipe 6-2 to the standard section of the spray branch pipe 6-4; determine the overhang width of the safety net 5 according to the fall radius, thereby determining the length of the spray branch pipe 6 and the diagonal brace 3; assemble the standard section according to the required length; connect the standard section of the spray branch pipe 6-4 to the spray pipe 7 using a two-way threaded connector 6-3.

[0066] Step 4: Determine the overhang width of the safety net 5 based on the fall radius, thereby determining the length of the diagonal brace 3. Assemble the first section of the diagonal brace 3-2 and the standard section of the diagonal brace 3-4 according to the required length, and connect them using the diagonal brace connecting sleeve 3-3. Pass the sprinkler pipe 7 through the sprinkler pipe sleeve 9-1, connect the sprinkler pipe 7 and the diagonal brace 3, and adjust the fastening bolt 9-3 so that the gap between the fastening bolt 9-3 and the sprinkler pipe 7 is less than 1mm but not tightened, so that the T-shaped connector 9 can rotate freely around the sprinkler pipe 7.

[0067] Step 5: Insert the end of the diagonal brace 3 into the diagonal brace sleeve 9-2. The diagonal brace 3 and the T-shaped connector 9 are connected through the connector plug 9-4. The connector pin 9-5 passes through the pin hole on the connector plug 9-4 to fix the plug.

[0068] Step 6: Install hinged couplers 8 on the outer uprights of the scaffold. Couplers 8 are connected to the diagonal brace 3 and the sprinkler branch pipe 6 through the plug 8-2 to form a hinge. The pin 8-3 passes through the pin hole on the plug 8-2 to fix the plug 8-2.

[0069] Step 7: Repeat step 5 to install and connect the sprinkler pipe 7 and the horizontal support 4; install the safety net 5 on the sprinkler pipe 7 and the horizontal support 4. After the safety net 5 is securely tied, install the hinge coupler 8 on the outer upright of the scaffold. The hinge coupler 8 and the horizontal support 4 are connected by the pin 8-2 to form a hinge; the pin 8-3 passes through the pin hole on the nut 8-2 to fix the nut.

[0070] Step 8: Connect the sprinkler water to the main sprinkler pipe 10 through the sprinkler branch pipe joint 6-5; complete the installation of the safety net support system and the sprinkler system;

[0071] Step 9: Start dust monitoring. Based on the dust monitoring feedback, control the spray water pump. After the pump is turned on, the water flows through the main spray pipe 10 into the spray branch pipe 6, and then flows into the spray pipe 7 through the bidirectional threaded joint 6-3 connecting the spray branch pipe 6 and the spray pipe 7. The water then forms an atomized spray effect through the atomizing spray head 7-1.

[0072] Step 10: When there are falling objects on the safety net, pull out the limit pin on the horizontal support 4, retract the pull rope 4-3, and retract the horizontal support 4 to retrieve the entire support system. Clear the objects from the safety net. When dismantling the scaffold, disconnect the sprinkler branch pipe joint 6-5 from the sprinkler main pipe 10 and retrieve the entire support system. Remove the safety net 5 and the horizontal support 4, and then pull out the pin connecting the diagonal brace 3 to the outer upright of the scaffold to complete the dismantling of the support system and the sprinkler system.
