Description

Technical Field

[0001] This invention relates to the field of building construction equipment, specifically to a construction device and construction method for a prefabricated unit attached to a communication repeater building. Background Technology

[0002] The interior of a communication repeater house houses components or modules such as antennas, radio frequency duplexers, and low-noise amplifiers. Most of these components are electronic. The design of the repeater house prevents these components from being corroded by rainwater during rainy weather, protecting these electronic components from external damage.

[0003] Communication repeater buildings are generally constructed from prefabricated walls and frames. Both the prefabricated walls and frames can be disassembled and installed. When the prefabricated walls are damaged, they need to be replaced promptly. However, in existing repeater building construction techniques, replacement is usually carried out only when the weather is clear and good. This leads to the inability to repair damaged prefabricated walls in a timely manner, resulting in a reduction in the overall protection performance of the repeater building for internal electronic components. Therefore, to solve the above problems, we propose a construction device and construction method for ancillary prefabricated units for communication repeater buildings. Summary of the Invention

[0010] Preferably, the assembly connector includes a U-shaped connecting strip inserted into a slot, a connecting block is fixedly connected to one end of the U-shaped connecting strip, a locking block A is fixedly connected to one end of the connecting block, and locking blocks B are fixedly connected to both the upper and lower sides of the rear end of the U-shaped connecting strip.

[0011] Preferably, the card block A is inserted into the side groove, and the connecting block is inserted into the limiting groove.

[0012] Preferably, ventilation components are fixedly connected to the prefabricated wall panels on both sides of the repeater house, and a pipe is fixedly connected to the lower side of the ventilation components. Openings are fixedly connected to the ceiling components on both sides of the upper end of the repeater house. The openings are located on the lower side of the nine-square grid frame, and a telescopic hose is fixedly connected to the lower end of the opening. The lower end of the telescopic hose is provided with a clamp.

[0013] Preferably, the ventilation component includes a ventilation duct, a three-phase motor is installed inside the ventilation duct, a fan is connected to the output shaft of one end of the three-phase motor via a coupling, the three-phase motor is connected to a forward / reverse switch via wires, and a sealing ring is provided at one end of both the ventilation duct and the connecting pipe.

[0014] A construction method for a prefabricated unit construction device attached to a communication repeater building, the construction method comprising the following steps:

[0015] Step A: During the construction of the repeater house and auxiliary houses, the nine-square grid frame and the prefabricated wall panels can be connected by welding or by fixing with connectors. The lower support frame and the prefabricated wall panels are fixed in the same way. Then, the entire opening and closing door is placed vertically between the two prefabricated support column structures.

[0016] Step B: Next, the assembly connectors are inserted into the slots in the precast wall panels. The locking block A is inserted into the side slot, the connecting block is inserted into the limiting slot, and the U-shaped connecting strip and the locking block B are both inserted into the slots. This makes the precast wall panels and the precast support column structure fixedly connected. The ceiling components are laid in the frame of the nine-square grid to form a complete repeater house and ancillary houses.

[0017] Step C: When the prefabricated wall panels on the outside of the repeater house or the ceiling components on the top of the repeater house need to be replaced, the prefabricated wall panels or ceiling components need to be replaced. If the weather is rainy during the construction, the water-proof component can be removed from the connecting hook at the bottom of the connecting plate, and the entire water-proof component can be unfolded. The unfolded water-proof component is then wrapped around the outside of the entire repeater house.

[0018] Step D: The connecting strip is aligned with the prefabricated support column structure at the four corners of the repeater building, and the inner surface of the waterproof cloth is aligned with the prefabricated wall panels on the four sides of the repeater building. Then, the retaining ring at one end of the connecting strip is engaged in the side groove, so that the overall prefabricated support column structure can be mounted on the connecting strip and the connecting strip.

[0019] Step E: Next, align the lower end of the flexible hose inside the repeater house with the ventilation component, and fix the clamp at the lower end of the flexible hose to the sealing ring on the ventilation pipe in the ventilation component. Turn on the forward and reverse switch on the three-phase motor so that the motor drives the fan to rotate forward. This blows outside air into the flexible hose through the ventilation pipe. The air is discharged upward from the opening. The discharged gas blows the water-proof cloth in the water-proof component upward, thereby increasing the distance between the inner surface of the overall water-proof cloth and the outer surface of the overall repeater house. This facilitates the maintenance and construction operations of the prefabricated wall panels and ceiling components on the repeater house.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention involves replacing prefabricated wall panels or ceiling components. If the weather is rainy during construction, the water-shielding component can be removed from the connecting hook at the bottom of the connecting plate, and the entire water-shielding component can be unfolded. The unfolded water-shielding component wraps around the outside of the entire repeater house. The setting and operation of the water-shielding component allows the repeater house to be constructed and repaired in rainy weather, thereby enabling the prefabricated wall surface of the repeater house to be repaired and maintained in a timely manner.

[0022] 2. This invention aligns the lower end of the flexible hose inside the repeater house with the ventilation component, and fixes the clamp at the lower end of the flexible hose to the sealing ring on the ventilation pipe in the ventilation component. When the forward and reverse switch on the three-phase motor is turned on, the motor drives the fan to rotate forward, and then the outside air is blown into the flexible hose through the ventilation pipe. The air is discharged upward from the opening, and the discharged gas blows the water-proof cloth in the water-proof component upward, thereby increasing the distance between the inner surface of the overall water-proof cloth and the outer surface of the overall repeater house, which facilitates the maintenance operations of the prefabricated wall panels and ceiling components on the repeater house.

[0023] 3. When the water-shielding cloth in this invention is blown upwards by gas, the entire water-shielding component also shifts upwards. However, because the retaining ring at one end of the connecting short strip is engaged in the side groove, the side groove and the retaining block can hold the connecting short strip and the connecting long strip, preventing the entire water-shielding component from being blown away by the upward gas. The upward-blowing gas exerts an upward thrust on the entire connecting long strip and the water-shielding cloth. This thrust also acts on the connecting short strip and the retaining ring, giving the connecting short strip an upward pulling force. This pulling force improves the retaining performance of the retaining ring at one end of the connecting short strip in the side groove, making it less likely for the entire water-shielding component to detach from the surface of the repeater house during maintenance operations. The overall water-shielding component also allows workers to perform maintenance and construction on the repeater house during rainy weather. The overall water-shielding component blocks rainwater, preventing rainwater from flowing into the repeater house during construction and causing corrosion, short circuits, or other damage to the internal electronic equipment.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Please see Figures 1 to 7 An embodiment of the present invention provides a prefabricated unit construction device for a communication repeater house, comprising a repeater house and an auxiliary house. The auxiliary house is provided on one side of the repeater house. Both the repeater house and the auxiliary house include a nine-square grid frame 2. Prefabricated support column structures 6 are fixedly connected to the four corners of the lower end of the nine-square grid frame 2. Prefabricated wall panels 4 are snapped between two prefabricated support column structures 6. Multiple slots 11 are arranged on both sides of the front end face of the prefabricated wall panels 4. Assembly connectors 9 are inserted into the slots 11. A switch door 1 is provided at the front end of one of the prefabricated wall panels 4. The lower ends of the four prefabricated support column structures 6 are fixedly connected to a lower support frame 10. Multiple floor panels 5 are spliced ​​at the lower end of the lower support frame 10.

[0034] The repeater house has a nine-square grid frame 2 at the top, and each of the frames is fitted with a ceiling piece 3. The eight frames of the nine-square grid frame 2 at the top of the auxiliary house are fixedly connected to the ceiling piece 3. The middle frame of the nine-square grid frame 2 at the top of the auxiliary house is fixedly connected with a connecting plate 7. The ceiling piece 3 is made of transparent plastic, and sunlight can shine through the ceiling piece 3 to the repeater house and the auxiliary house during the day. This setting increases the brightness inside the house and also replaces the existing electric lights, so that electric lights are no longer used during the day, thereby saving energy and operating costs.

[0035] The lower end of the connecting plate 7 is fixedly connected to a connecting hook 16, and the lower end of the connecting hook 16 is hung with a water-proof component 8. The prefabricated support column structure 6 includes a support column 601 fixedly connected to the lower end of the nine-square grid frame 2. Multiple side grooves 602 are arranged along the edge of the support column 601. The upper and lower end faces of the side grooves 602 are fixedly connected to the snap-fit ​​blocks 603. Multiple side grooves 604 are provided on both sides of the support column 601. A limiting groove 605 is fixedly provided at one end of the side groove 604. Multiple limiting grooves 605 and multiple slots 11 are aligned one by one.

[0036] The water-blocking component 8 includes a hook 804 mounted on the lower end of the connecting hook 16. A connecting plate 803 is fixedly connected to the lower end of the hook 804. Four connecting strips 801 are fixedly connected around the connecting plate 803. A water-blocking cloth 802 is fixedly connected between two connecting strips 801. Multiple connecting short strips 805 are fixedly connected to the inner surface of the connecting strips 801. A retaining ring 806 is fixedly connected to one end of the connecting short strips 805. The retaining ring 806 is engaged in the side groove 602.

[0037] The aforementioned assembly connector 9 includes a U-shaped connecting strip 903 inserted into a slot 11. A connecting block 902 is fixedly connected to one end of the U-shaped connecting strip 903, and a locking block A901 is fixedly connected to one end of the connecting block 902. Locking blocks B904 are fixedly connected to both the upper and lower sides of the rear end of the U-shaped connecting strip 903. Locking block A901 is inserted into a side groove 604, and connecting block 902 is inserted into a limiting groove 605. This arrangement allows locking blocks A901 and connecting blocks 902 in the assembly connector 9 to engage with the surface of the prefabricated support column structure 6, wherein the inner side of the U-shaped connecting strip 903 is inserted into the slot 11. The U-shaped connecting strip 903 and the locking block B904 are used to lock and fix the precast wall panel 4, thereby realizing the fixed connection between the precast support column structure 6 and the precast wall panel 4. The U-shaped connecting strip 903 has its own elasticity, which makes it easy for the locking block B904 to be locked in the slot 11. At the same time, the cross-section of the locking block B904 is designed as a trapezoidal structure, so the vertical end face of one end of the locking block B904 is easy to fit with the inner end of the slot 11. As a result, the overall assembly connector 9 is not easy to detach from the slot 11, which further improves the fixed connection performance between the overall assembly connector 9 and the precast wall panel 4 and the precast support column structure 6.

[0038] Ventilation components 14 are fixedly connected to the prefabricated wall panels 4 on both sides of the repeater house. A pipe 15 is fixedly connected to the lower side of the ventilation component 14. An opening 13 is fixedly connected to the ceiling components 3 on both sides of the upper end of the repeater house. The opening 13 is located on the lower side of the nine-square grid frame 2. A flexible hose 12 is fixedly connected to the lower end of the opening 13. A clamp is provided at the lower end of the flexible hose 12. The ventilation component 14 includes a ventilation pipe. A three-phase motor is installed inside the ventilation pipe. A fan is connected to the output shaft of one end of the three-phase motor through a coupling. The three-phase motor is connected to a forward and reverse switch through a wire. A sealing ring is provided at one end of both the pipe 15 and the ventilation pipe.

[0039] During the construction, operation, and maintenance of the repeater house, the lower end of the flexible hose 12 inside the repeater house needs to be aligned with the ventilation component 14, and the clamp at the lower end of the flexible hose 12 needs to be fixedly connected to the sealing ring on the ventilation pipe in the ventilation component 14. Turn on the forward and reverse switch on the three-phase motor so that the motor drives the fan to rotate forward, and then blow outside air into the flexible hose 12 through the ventilation pipe. The air is discharged upward from the opening 13. The discharged gas blows the water-proof cloth 802 in the water-proof component 8 upward, thereby increasing the distance between the inner surface of the water-proof cloth 802 and the outer surface of the repeater house, which facilitates the maintenance operation of the prefabricated wall panel 4 and ceiling component 3 on the repeater house.

[0040] When the waterproof cloth 802 is blown upward by the gas, the entire waterproof component 8 also moves upward. However, because the retaining ring 806 at one end of the connecting short strip 805 is engaged in the side groove 602, the side groove 602 and the retaining block 603 can hold the connecting short strip 805 and the connecting long strip 801, preventing the entire waterproof component 8 from being blown away by the upward gas. The upward-blowing gas exerts an upward thrust on the entire connecting long strip 801 and the waterproof cloth 802. This thrust also acts on the connecting short strip 805 and the retaining ring 806, causing the connecting short strip 805 to move upward. The connecting strip 805 has an upward tensile force, which improves the locking performance of the retaining ring 806 at one end of the connecting strip 805 in the side groove 602. This makes it difficult for the overall water-proof component 8 to detach from the surface of the repeater house during maintenance operations. The overall water-proof component 8 also allows maintenance work to be carried out on the repeater house during rainy weather. The overall water-proof component 8 blocks rainwater, preventing rainwater from flowing into the repeater house during construction and causing corrosion, short circuits, or other damage to the internal electronic equipment.

[0041] After the maintenance of the precast wall panel 4 and ceiling component 3 is completed, the forward and reverse switch of the three-phase motor in the ventilation component 14 needs to be turned off so that the gas generated in the ventilation component 14 no longer blows upward through the telescopic hose 12 and the inlet 13. Then, the connecting strip 801 in the overall water-proof component 8 is bent and folded inward, and the water-proof cloth 802 is also bent and folded inward. Then, it is bent and folded along the center line of the water-proof cloth 802, so that the overall water-proof component 8 is in a folded and bent state. It is then hung in the connecting hook 16 at the lower end of the connecting plate 7 through the hook 804 on the connecting plate 803. The connecting plate 7 is fixed to the top of the auxiliary house, and the water-proof component 8 is placed in the auxiliary house. The auxiliary house can also hold maintenance tools for other electronic and electrical components.

[0042] After the replacement and repair of the ceiling components 3 and prefabricated wall panels 4 on the entire repeater house are completed, the lower end clamps of the telescopic hose 12 and the sealing rings on the through pipe 15 inside the repeater house are fixedly connected. At this time, the entire repeater house is exposed to the outside. When the weather is cloudy or rainy, rainwater will be discharged outward through the opening 13, the telescopic hose 12 and the through pipe 15, making it difficult for water to accumulate on the top of the entire repeater house. At the same time, the forward and reverse switch of the three-phase motor inside the ventilation component 14 is turned to the reverse position, so that the motor drives the fan blades to draw air outward, reducing the condensation of water vapor inside the repeater house on cloudy or rainy days.

[0043] A construction method for a prefabricated unit construction device attached to a communication repeater building, the construction method comprising the following steps:

[0044] Step A: During the construction of the repeater house and the ancillary house, the nine-square grid frame 2 and the prefabricated wall panel 4 can be connected by welding or by fixing with connectors. The lower support frame 10 and the prefabricated wall panel 4 are fixedly connected in the same way. Then, the entire opening and closing door 1 is placed vertically between the two prefabricated support column structures 6.

[0045] Step B: Next, the assembly connector 9 is inserted into the slot 11 on the prefabricated wall panel 4. The locking block A901 is inserted into the side groove 604, the connecting block 902 is inserted into the limiting groove 605, and the U-shaped connecting strip 903 and the locking block B904 are both inserted into the slot 11. This makes the prefabricated wall panel 4 and the prefabricated support column structure 6 fixedly connected. The ceiling piece 3 is laid in the frame of the nine-square grid 2, thus forming a complete repeater house and ancillary houses.

[0046] Step C: When the prefabricated wall panel 4 on the outside of the repeater house or the ceiling component 3 on the top of the repeater house needs to be replaced, the prefabricated wall panel 4 or the ceiling component 3 needs to be replaced. If the weather is rainy during the construction, the water-proof component 8 can be removed from the connecting hook 16 at the bottom of the connecting plate 7, and the entire water-proof component 8 can be unfolded. The unfolded water-proof component 8 is wrapped around the outside of the entire repeater house.

[0047] Step D: The connecting strip 801 is aligned with the prefabricated support column structure 6 at the four corners of the repeater building, and the inner surface of the waterproof cloth 802 is aligned with the prefabricated wall panel 4 on the four sides of the repeater building. Then, the retaining ring 806 at one end of the connecting strip 805 is engaged in the side groove 602, so that the entire prefabricated support column structure 6 is mounted on the connecting strip 805 and the connecting strip 801.

[0048] Step E: Next, align the lower end of the flexible hose 12 inside the repeater house with the ventilation component 14, and fix the clamp at the lower end of the flexible hose 12 to the sealing ring on the ventilation pipe in the ventilation component 14. Turn on the forward and reverse switch on the three-phase motor so that the motor drives the fan to rotate forward. Then, the outside air is blown into the flexible hose 12 through the ventilation pipe. The air is discharged upward from the opening 13. The discharged gas blows the water-proof cloth 802 in the water-proof component 8 upward, thereby increasing the distance between the inner surface of the water-proof cloth 802 and the outer surface of the repeater house, which facilitates the maintenance and construction operations of the prefabricated wall panels 4 and ceiling components 3 on the repeater house.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

Step C: When the precast wall panel (4) on the outside of the repeater house or the ceiling component (3) on the top of the repeater house needs to be replaced, the precast wall panel (4) or the ceiling component (3) needs to be replaced. If the weather is cloudy and rainy during the construction, the water-proof component (8) can be removed from the connecting hook (16) at the bottom of the connecting plate (7), and the entire water-proof component (8) can be unfolded. The unfolded water-proof component (8) is wrapped around the outside of the entire repeater house. Step D: The connecting strip (801) is aligned with the prefabricated support column structure (6) at the four corners of the repeater building, and the inner surface of the waterproof cloth (802) is aligned with the prefabricated wall panel (4) on the four sides of the repeater building. Then, the retaining ring (806) at one end of the connecting strip (805) is engaged in the side groove (602), so that the overall prefabricated support column structure (6) hangs the connecting strip (805) and the connecting strip (801). Step E: Next, align the lower end of the telescopic hose (12) inside the repeater house with the ventilation component (14), and fix the clamp at the lower end of the telescopic hose (12) to the sealing ring on the ventilation pipe in the ventilation component (14). Turn on the forward and reverse switch on the three-phase motor so that the motor drives the fan to rotate forward. Then, the outside air is blown into the telescopic hose (12) through the ventilation pipe. The air is discharged upward from the opening (13). The discharged gas blows the water-proof cloth (802) in the water-proof component (8) upward, thereby increasing the distance between the inner surface of the overall water-proof cloth (802) and the outer surface of the overall repeater house, which facilitates the maintenance and construction operations of the prefabricated wall panels (4) and ceiling components (3) on the repeater house.
