Technical Field
[0001] The present application relates to the technical field of building construction, and in particular to a structure used for building construction. Background Art
[0002] At present, in the process of improving the pipeline technology of construction, the addition of new processes will involve the docking of new and old process pipelines. Most of the valves involved in the old pipelines cannot be completely closed due to aging, resulting in the need for water-carrying docking in the renovation and expansion project. However, the water-carrying pipeline will wet the docking parts during the docking process, thus affecting the welding quality of the welding link in the docking step. Summary of the invention
[0003] In order to reduce the impact of water flow in old pipes on welding links, the present application provides a structure for building construction.
[0004] The present application provides a structure for building construction using the following technical solution: A structure used for building construction, comprising a docking warehouse, with old pipe connection ports and new pipe connection ports respectively provided on both sides of the docking warehouse; a sealing airbag, with an airbag interface provided on one side of the docking warehouse, the sealing airbag is arranged in the docking warehouse, and the inflation channel of the sealing airbag is connected to the outside of the docking warehouse through the airbag interface.
[0005] By adopting the above technical solution, the old pipe connecting port is used to connect with the old pipe, and the new pipe connecting port is used to connect with the new pipe. Air is pumped into the sealing airbag to fill the cross-section of the docking bin. Then the old pipe is matched with the old pipe connecting port. At this time, the water flow in the old pipe cannot pass through the docking bin, thereby reducing the impact of the water flow in the old pipe on the welding process.
[0006] Optionally, an isolation plate is provided in the docking warehouse, and the isolation plate divides the docking warehouse into a blocking area and a buffer area. A channel connecting the blocking area and the buffer area is provided on the isolation plate. The blocking airbag is arranged in the blocking area, the new tube connection port and the airbag interface are connected to the blocking area, and the old tube connection port is connected to the buffer area.
[0007] By adopting the above technical solution, the space in the docking bin can be divided by isolation plates. Since the area where the blocking airbag is located is smaller, the blocking airbag can fill the space more quickly, so that the water flow in the old pipe cannot pass through the docking bin, thereby reducing the impact of the water flow in the old pipe on the welding process.
[0008] Optionally, the channel is constructed as a plurality of connecting ports, and the sum of the flow areas of the plurality of connecting ports, the flow area of the old pipe connecting port, and the flow area of the new pipe connecting port are all the same.
[0009] By adopting the above technical solution, the channel constructed with multiple connecting ports can enable the isolation plate to more effectively limit the expansion space of the blocking airbag, avoid part of the structure of the blocking airbag from reaching the buffer zone through the channel, and limit the sum of the flow areas of the multiple connecting ports, so that the water flow can easily reach the blocking area from the buffer zone through the channel when the blocking airbag is not inflated, thereby flowing into the new pipeline.
[0010] Optionally, a pressure relief port is further provided on the docking bin, and the pressure relief port is communicated with the buffer zone.
[0011] By adopting the above technical solution, when the sealing air bag fills the cross-section of the docking bin, since the water in the old water pipe cannot pass through the docking bin, the water in the old water pipe will remain in the buffer zone and gradually accumulate pressure, thereby generating a force to push the docking structure away from the old water pipe. Some water in the old water pipe will even pass through the tiny gap between the sealing air bag and the wall of the docking bin and reach the connection port of the new pipe, affecting normal construction. The pressure relief port can discharge the water in the buffer zone in time, thereby reducing the pressure in the docking bin.
[0012] Optionally, the pressure relief port is connected to a pressure relief pipe, and the pressure relief pipe is provided with a pressure relief pump.
[0013] By adopting the above technical solution, the rate of draining water from the buffer zone can be accelerated by using a pressure relief pump.
[0014] Optionally, a pressure sensor is provided on one side of the isolation plate close to the old pipe connection port, and the pressure sensor is connected to the pressure relief pump signal.
[0015] By adopting the above technical solution, the pressure sensor can detect the pressure in the current buffer zone, thereby controlling the start and stop or power of the pressure relief pump according to the pressure.
[0016] Optionally, an old pipe connection part is provided at the old pipe connection port, the old pipe connection part is tubular in structure, the old pipe connection part is coaxially arranged with the old pipe connection port, and the inner diameter of the old pipe connection part matches the outer diameter of the old pipe, and / or, a new pipe connection part is provided at the new pipe connection port, the new pipe connection part is tubular in structure, the new pipe connection part is coaxially arranged with the new pipe connection port, and the inner diameter of the new pipe connection part matches the outer diameter of the new pipe.
[0017] By adopting the above technical solution, the old pipe connection part and the new pipe connection part can facilitate the old pipe and the new pipe to match with the old pipe connection port and the new pipe connection port.
[0018] Optionally, an inflation tube is provided at the airbag interface, a first connecting flange is provided at one end of the inflation tube away from the docking bin, and a second connecting flange matching with the first connecting flange is provided at one end of the inflation channel away from the blocking airbag.
[0019] By adopting the above technical solution, the inflation channel with the second connecting flange can cooperate with the inflation pipe with the first connecting flange, so as to facilitate inflation into the blocking airbag.
[0020] Optionally, the structure for building construction further comprises a sealing plug, one end of which is provided with a third connecting flange capable of matching with the first connecting flange and the second connecting flange.
[0021] By adopting the above technical solution, after completing the connection between the new pipeline and the old pipeline, the gas in the sealing airbag is released, and the sealing plug is installed at the air pumping pipe, so that the airbag interface can be closed to prevent water from leaking from the air pumping pipe during actual use.
[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up a docking bin and a plugging airbag, the plugging airbag can fill the cross section of the docking bin, so that the water flow in the old pipe cannot pass through the docking bin, thereby reducing the impact of the water flow in the old pipe on the welding process; 2. The connection chamber is divided into a blocking area and a buffer zone by setting an isolation plate. When the new and old pipes are connected, the blocking area can be blocked by the blocking airbag, so that water flows into the buffer zone from the connecting port, and part of the water in the buffer zone is discharged by setting a pressure relief port to reduce the water pressure in the buffer zone during the connection process, thereby reducing the burden on the connection port between the old pipe and the old pipe; 3. By setting the sealing plug, the airbag interface can be sealed after the new and old pipelines are connected, thereby improving the overall sealing performance of the structure used for construction.

DETAILED DESCRIPTION
[0025] The following is combined with Figure 1-3 This application is described in further detail.
[0026] The embodiment of the present application discloses a structure for building construction.
[0027] like Figure 1 and Figure 2 As shown, a structure used for construction includes a docking bin 1 and a blocking airbag 2. The docking bin 1 is provided with an old pipe connection port 101 and a new pipe connection port 102 on both sides, and the old pipe connection port 101 and the new pipe connection port 102 are used to connect with the old pipe and the new pipe respectively. The blocking airbag 2 is arranged in the docking bin 1, and is connected to the outside of the docking bin 1 through the airbag interface 103 for inflation. After the blocking airbag 2 is inflated, the blocking airbag 2 can fill the cross section of the docking bin 1, and then the old pipe is matched with the old pipe connection port 101. At this time, the water flow in the old pipe cannot pass through the docking bin 1, thereby reducing the influence of the water flow in the old pipe on the welding process.
[0028] like Figure 1 and Figure 2 As shown, a partition plate 3 may be provided in the docking bin 1, and the partition plate 3 divides the docking bin 1 into a blocking area 4 and a buffer area 5. A channel connecting the blocking area 4 and the buffer area 5 is provided on the partition plate 3, and the channel may be constructed as a plurality of connecting ports 6, and the sum of the flow areas of the plurality of connecting ports 6, the flow area of the old pipe connection port 101, and the flow area of the new pipe connection port 102 are all the same. The blocking airbag 2 is provided in the blocking area 4, the new pipe connection port 102 and the airbag interface 103 are connected to the blocking area 4, and the old pipe connection port 101 is connected to the buffer area 5.
[0029] The space in the docking chamber 1 can be divided by the isolation plate 3. Since the area where the plugging airbag 2 is located is smaller, the plugging airbag 2 can fill the space more quickly, so that the water flow in the old pipeline cannot pass through the docking chamber 1, thereby reducing the impact of the water flow in the old pipeline on the welding process. The channel structured as multiple connecting ports 6 can enable the isolation plate 3 to more effectively limit the expansion space of the plugging airbag 2, prevent part of the structure of the plugging airbag 2 from reaching the buffer zone 5 through the channel, and limit the total flow area of the multiple connecting ports 6, so that the water flow can easily reach the plugging area 4 from the buffer zone 5 through the channel when the plugging airbag 2 is not inflated, thereby flowing into the new pipeline.
[0030] like Figure 1 and Figure 2As shown, the docking chamber 1 is also provided with a pressure relief port 104, which is connected to the buffer zone 5. When the plugging airbag 2 fills the cross section of the docking chamber 1, since the water in the old water pipe cannot pass through the docking chamber 1, the water in the old water pipe will remain in the buffer zone 5 and gradually accumulate pressure, thereby generating a force to push the docking structure away from the old water pipe. Some water in the old water pipe may even pass through the tiny gap between the plugging airbag 2 and the wall of the docking chamber 1 and reach the new pipe connection port 102, affecting normal construction. The pressure relief port 104 can discharge the water in the buffer zone 5 in time, thereby reducing the pressure in the docking chamber 1.
[0031] like Figure 1 and Figure 2 As shown, in order to improve the pressure relief effect of the pressure relief port 104, a pressure relief pipe 108 is connected to the pressure relief port 104, and a pressure relief pump 8 can be provided on the pressure relief pipe 108. In the actual construction process, the pressure relief port 104 can be placed below the docking warehouse 1, and the water in the buffer zone 5 flows into the pressure relief pipe 108 under the action of gravity, and the pressure relief pump 8 can speed up the rate of drainage from the buffer zone 5.
[0032] In order to monitor the pressure condition of the buffer zone 5 in real time and control the drainage rate according to the pressure condition, a pressure sensor (not shown in the figure) is further provided on the side of the isolation plate 3 close to the old pipe connection port 101. The pressure sensor is connected to the pressure relief pump 8 by signal. The water in the buffer zone 5 directly acts on the diaphragm of the pressure sensor, causing the diaphragm to produce a micro-displacement proportional to the medium pressure, causing the resistance of the pressure sensor to change. This change is detected by an electronic circuit, and a standard signal corresponding to this pressure is converted and output to obtain the water pressure at the position of the pressure sensor at this time. The pressure sensor compares the current water pressure with the preset value, and sends a signal to control the pressure relief pump 8 according to the comparison result, so as to start the pressure relief pump 8 in time to relieve the pressure when the pressure is too high.
[0033] like Figure 1 and Figure 2 As shown, in order to facilitate the connection of the old pipe with the old pipe connection port 101 and the connection of the new pipe with the new pipe connection port 102, an old pipe connection portion 105 is provided at the old pipe connection port 101, and the old pipe connection portion 105 is tubular in structure, coaxially arranged with the old pipe connection port 101, and its inner diameter matches the outer diameter of the old pipe; similarly, a new pipe connection portion 106 is also provided at the new pipe connection port 102, and its structure is tubular, coaxially arranged with the new pipe connection port 102, and its inner diameter matches the outer diameter of the new pipe. The old pipe and the new pipe can be inserted into the old pipe connection portion 105 and the new pipe connection portion 106 respectively, and the old pipe connection portion 105 and the new pipe connection portion 106 can play a positioning role, which is convenient for construction personnel to perform welding operations.
[0034] like Figure 1 and Figure 2As shown, an air pumping tube 107 is provided at the airbag interface 103, and a first connecting flange 109 is provided at one end of the air pumping tube 107 away from the docking bin 1. A second connecting flange 202 matching with the first connecting flange 109 is provided at one end of the inflation channel 201 away from the blocking airbag 2, and an external inflation device can be conveniently connected through the first connecting flange 109 and the second connecting flange 202 to inflate the blocking airbag 2.
[0035] In addition, if Figure 3 As shown, the structure for construction provided by this embodiment may also include a sealing plug 7, one end of which is provided with a third connecting flange 701, and the third connecting flange 701 can cooperate with the first connecting flange 109 and the second connecting flange 202, so that when the inflation operation is not required, the airbag interface 103 is closed to ensure the airtightness of the structure, or after the new pipeline is connected to the old pipeline, the gas in the sealing airbag 2 is released and the airbag interface 103 is closed to ensure the airtightness of the structure.
[0036] The implementation principle of a structure used for building construction in the embodiment of the present application is as follows: During actual construction, the blocking airbag 2 is first inflated through the air pump 107 to expand the blocking airbag 2 and fill the space in the blocking area 4 , and then the blocking plug 7 is installed at the air pump 107 to close the airbag interface 103 .
[0037] Then, the old pipe is inserted into the old pipe connection part 105, so that the pipe opening of the old pipe matches the old pipe connection port 101 of the docking chamber 1. At this time, the water in the old pipe gradually flows into the buffer zone 5, and the pressure sensor on the side of the isolation plate 3 close to the old pipe connection port 101 starts to work. The pressure sensor controls the pressure relief pump 8 to run according to the reading, and the staff starts the welding operation between the old pipe and the old pipe connection part 105.
[0038] After completing the welding operation between the old pipe and the old pipe connection part 105 , the construction workers insert the new pipe into the new pipe connection part 106 so that the pipe opening of the new pipe matches with the new pipe connection opening 102 of the docking warehouse 1 . At this time, the workers start the welding operation between the new pipe and the new pipe connection part 106 .
[0039] After completing the welding operation between the new pipeline and the new pipe connection part 106, manually turn off the pressure relief pump 8, remove the sealing plug 7 from the inflation pipe 107, wait for the gas in the sealing airbag 2 to be released, and then reinstall the sealing plug 7 on the inflation pipe 107 to close the airbag interface 103.
[0040] After being put into actual use, the pressure sensor can continue to detect the pressure in the structure used for building construction, and use the pressure reading value as one of the indicators for judging whether the structure used for building construction is working normally.
[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
