Description

Technical Field

[0001] This invention belongs to the technical field of external power protection frames, specifically, it relates to an external power protection frame for building construction and a method for its construction. Background Technology

[0002] The construction industry has developed rapidly in my country in recent years. As a major infrastructure country, construction sites are ubiquitous. Construction work on construction sites usually requires the use of external power to support various tasks, such as lighting, power tools, and ventilation equipment. However, external power lines that are not properly protected may cause safety accidents such as electric shock and fire.

[0003] Because the new building is located close to the high-voltage power transmission line, it poses a potential threat to construction workers, construction equipment, and the surrounding environment, such as electric shock or fire caused by electric shock. Therefore, it is necessary to isolate and protect the high-voltage power line to prevent accidental electric shock to construction workers, guide construction equipment to prevent accidental contact, and avoid affecting the surrounding environment.

[0004] In traditional construction sites, simple installation methods are often used, such as suspending wires from buildings or brackets with nails or ropes. These methods are not only unstable but also prone to wire damage and accidental contact. Alternatively, protective frames are erected to protect high-voltage cables and warn construction workers and equipment. However, existing protective frames are susceptible to damage from severe weather, such as strong winds and typhoons, because their tops are made of insulation. This makes them vulnerable to damage from strong winds, and because the insulated tops are close to the high-voltage cables, they can easily damage the cables and cause serious consequences. Summary of the Invention

[0005] In view of this, the present invention provides an external power protection frame and a method for constructing buildings, which can enhance the protection capability of external high-voltage cables, increase the wind resistance of the protective frame, and improve the safety of external power protection.

[0006] This invention is implemented as follows:

[0007] This invention provides a protective frame for external electrical installations in building construction. The frame includes a protective base, comprising horizontal steel pipes, connecting supports, and longitudinal uprights. The horizontal steel pipes are fixedly connected to the connecting supports via fasteners, and the longitudinal uprights are also fixedly connected to the horizontal steel pipes via fasteners. A reinforcement zone is provided at the top of the protective base, comprising reinforcement uprights and reinforcement crossbars. The reinforcement uprights are fixedly connected to the horizontal steel pipes via fasteners, and the reinforcement uprights and reinforcement crossbars are fixedly installed via fasteners. An auxiliary support is provided in the reinforcement zone to further reinforce the protective frame and enhance its support strength. A bamboo protection zone is attached to the top of the reinforcement zone, comprising bamboo uprights, large bamboo crossbars, and small bamboo crossbars. A safety net and warning flags are provided at the top of the bamboo protection zone.

[0008] The technical effects of the external power protection frame for building construction provided by this invention are as follows: the protective frame is constructed by setting a protective base frame and then building it upwards; the reinforcement area is set to strengthen the middle and bottom of the protective frame; the bamboo protection area is set to protect the high-voltage cables at the top; and the warning flags are set to remind and warn the tower crane construction equipment.

[0009] Based on the above technical solution, the external electrical protection frame for building construction of the present invention can be further improved as follows:

[0010] Optionally, the bottom of the protective base is connected to a pre-embedded base, which includes a pre-embedded end and a connecting end. The bottom of the pre-embedded end is provided with a pre-embedded pile, and the connecting end is used to fix and install the transverse steel pipe.

[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting up a pre-embedded base, the connection strength between the ground and the protective frame is strengthened, the wind resistance of the protective frame is enhanced, and the protective frame is prevented from being affected by strong winds and causing damage to the surrounding environment.

[0012] Furthermore, the last row of reinforcing poles in the reinforced area is equipped with a movable connecting kit. The top of the reinforcing pole has a threaded hole that matches the movable connecting kit. The bottom of the movable connecting kit is fixed to the top of the reinforcing pole with bolts. The top of the movable connecting kit is fixed to a connecting pole with bolts. The connecting pole is used to bind and fix the bamboo poles. In the bamboo protection area, except for the last row of bamboo poles which are fixed to the bottom reinforcing poles by the movable connecting kit after binding the connecting poles, the bamboo poles in other rows are fixed to the bottom reinforcing poles by disassembling the connecting kits after binding the connecting poles.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by fixing the last bamboo pole to the reinforcing pole through the movable connecting kit, and by fixing the front bamboo pole to the reinforcing pole through the disassembly of the connecting kit, the bamboo protection area of ​​the protective frame can be laid down after a strong typhoon weather warning is issued in the local area, so as to avoid the typhoon damaging the bamboo protection area and thus affecting the high-voltage cables, thereby enhancing the protective safety of the protective frame.

[0014] Furthermore, the movable connection kit includes an upper end, a lower end, and a pivot. The upper end is used to fix the connecting pole, and the lower end is used to fix the reinforcing pole at the bottom. The upper end and the lower end facing outwards from the frame are connected by a pivot, and the ends facing inwards from the frame are detachably connected by bolts. The detachable connection kit includes an upper end and a lower end. The upper end and the left and right sides of the lower end are detachably connected by bolts. An anchor plate is provided on the ground on the rotating side of the pivot, and a fixing steel cable is provided on the anchor plate. The other end of the fixing steel cable is fixedly connected to the large horizontal bamboo pole of the bamboo protection area.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting anchor plates and connecting and fixing steel cables, the bamboo protection area is protected and fixed, and the wind resistance and safety of the protective frame are enhanced.

[0016] This invention provides a method for constructing an external electrical protection frame for building construction, comprising the following steps:

[0017] S10: Level the site, calculate the safety distance based on the location of the high-voltage line, mark the location of the construction point, and drill holes at the marked construction point;

[0018] S20: Install pre-embedded parts according to the drilling points and construct the protective frame base;

[0019] S30: Construct a reinforced area on top of the protective frame base;

[0020] S40: Construct a protective area on top of the reinforced area of ​​the protective frame.

[0021] Based on the above technical solution, the method for constructing an external electrical protection frame according to the present invention can be further improved as follows:

[0022] Furthermore, the specific steps for leveling the site, calculating the safety distance based on the location of the high-voltage line, marking the location of the erection point, and drilling holes at the marked erection point include:

[0023] The site within the construction area was leveled, and the safe distance was calculated based on the location of the high-voltage line. The ground was measured and laid out using a total station according to the design dimensions, and benchmark points were marked and set up. Drilling was carried out at the corresponding benchmark point locations using drilling equipment.

[0024] Furthermore, the specific steps for constructing the protective frame base by embedding pre-embedded parts according to the drilling points include:

[0025] The pre-embedded bases are placed into the drilled holes one by one, leaving the connection ends exposed. The connection ends of the pre-embedded bases are checked for horizontality using a line and a level measuring instrument to ensure that the connection ends are aligned horizontally. Then, reinforced concrete is injected into the holes. After the concrete dries completely, horizontal steel pipes are installed through the connection ends of the pre-embedded bases. Connecting supports are installed between the horizontal steel pipes using connecting fasteners to construct the base frame of the protective frame. Longitudinal uprights are installed on the connecting supports using connecting fasteners. The horizontal steel pipes are 200mm away from the ground, the longitudinal uprights are 1.8m apart, and the horizontal spacing is 1m.

[0026] Furthermore, the specific steps for constructing a reinforcement area on top of the protective frame base include:

[0027] Reinforcing uprights are erected along the top of the longitudinal uprights using connecting sleeves. During the erection of reinforcing uprights, the reinforcing uprights at both ends should be erected first, followed by the reinforcing uprights in the middle. After the reinforcing uprights are erected, check that the body of the reinforcing upright is perpendicular to the lower longitudinal upright. Then, install the reinforcing horizontal bars. When installing the reinforcing horizontal bars, the step distance should be 1.5m. When installing the reinforcing horizontal bars on the first step of the frame, it is necessary to check whether the reinforcing horizontal bars are perpendicular and secure to the reinforcing uprights. When the reinforcement area of ​​the protective frame is erected to three steps or more, diagonal bracing and scissor bracing should be tied on.

[0028] Furthermore, the specific steps for constructing the protective area on top of the reinforced area of ​​the protective frame include:

[0029] Install connecting poles at the top of the last row of reinforcing poles in the reinforcement area using movable connecting kits. Connect the remaining reinforcing poles requiring connecting poles by disassembling the connecting kits. Tie bamboo poles to the connecting poles, prioritizing the binding of the two ends before binding the middle poles. After binding, ensure the poles are aligned vertically and horizontally. After pole installation, install the large bamboo horizontal bars in the protection area, ensuring the larger ends of the large bamboo horizontal bars at both ends of the protective frame face outwards. When installing the large horizontal bars on the first step of the protective area, check that the bamboo poles are vertical and secure. The larger ends of the large horizontal bars on the same step should face the same direction, while the larger ends of adjacent steps should face opposite directions to enhance the overall stability of the protective frame. Bind small horizontal bars between the large horizontal bars, with adjacent small horizontal bars facing opposite directions. Bind the small horizontal bars to the poles, with adjacent rows of small horizontal bars bound to different sides of the poles. The length of the small horizontal bars extending beyond the pole should not be less than 300mm.

[0030] Furthermore, after the protective area is installed, a safety net should be erected on top of the protective area, and an anchor plate should be set on the ground at the back end of the protective frame. A steel cable should be wrapped around the anchor plate and fixedly connected to the other end of the steel cable to the bamboo crossbar of the protective area for wind protection.

[0031] Compared with existing technologies, the beneficial effects of the construction external power protection frame and its construction method provided by this invention are as follows: The protective frame is constructed by sequentially building upwards from a protective base frame; a reinforcement zone is set up to strengthen the middle and bottom of the protective frame; a bamboo protection zone is set up to protect the high-voltage cables at the top; warning flags are set up to remind and warn tower crane construction equipment; a pre-embedded base is set up to strengthen the connection between the ground and the protective frame, enhancing the wind resistance of the protective frame and preventing strong winds from affecting the surrounding environment; the bamboo poles at the very end are fixed to the reinforcement poles using movable connecting kits, and the bamboo poles at the front end are fixed to the reinforcement poles by disassembling the connecting kits. This allows the bamboo protection zone of the protective frame to be lowered after a strong typhoon weather warning is issued, preventing the typhoon from damaging the bamboo protection zone and affecting the high-voltage cables, thus enhancing the protective safety of the protective frame.

[0045] like Figure 5 The diagram shows a method for constructing an external electrical protection frame according to the present invention, comprising the following steps:

[0046] S10: Level the site, calculate the safety distance based on the location of the high-voltage line, mark the location of the construction point, and drill holes at the marked construction point;

[0047] S20: Install pre-embedded parts according to the drilling points and construct the protective frame base;

[0048] S30: Construct a reinforced area on top of the protective frame base;

[0049] S40: Construct a protective area on top of the reinforced area of ​​the protective frame.

[0050] Furthermore, in the above technical solution, the specific steps of leveling the site, calculating the safety distance based on the location of the high-voltage line, marking the location of the erection point, and drilling holes at the marked erection point include:

[0051] The site within the construction area was leveled, and the safe distance was calculated based on the location of the high-voltage line. The ground was measured and laid out using a total station according to the design dimensions, and benchmark points were marked and set up. Drilling was carried out at the corresponding benchmark point locations using drilling equipment.

[0052] Furthermore, in the above technical solution, the specific steps for constructing the protective frame base by embedding pre-embedded parts according to the drilling points include:

[0053] The pre-embedded bases are placed into the drilled holes one by one, leaving the connection ends exposed. The connection ends of the pre-embedded bases are checked for horizontality using a line and a level measuring instrument to ensure that the connection ends are aligned horizontally. Then, reinforced concrete is injected into the holes. After the concrete dries completely, horizontal steel pipes are installed through the connection ends of the pre-embedded bases. Connecting supports are installed between the horizontal steel pipes using connecting fasteners to construct the base frame of the protective frame. Longitudinal uprights are installed on the connecting supports using connecting fasteners. The horizontal steel pipes are 200mm away from the ground, the longitudinal uprights are 1.8m apart, and the horizontal spacing is 1m.

[0054] Furthermore, in the above technical solution, the specific steps for constructing a reinforcement area on top of the protective frame base include:

[0055] Reinforcing uprights are erected along the top of the longitudinal uprights using connecting sleeves. During the erection of reinforcing uprights, the reinforcing uprights at both ends should be erected first, followed by the reinforcing uprights in the middle. After the reinforcing uprights are erected, check that the body of the reinforcing upright is perpendicular to the lower longitudinal upright. Then, install the reinforcing horizontal bars. When installing the reinforcing horizontal bars, the step distance should be 1.5m. When installing the reinforcing horizontal bars on the first step of the frame, it is necessary to check whether the reinforcing horizontal bars are perpendicular and secure to the reinforcing uprights. When the reinforcement area of ​​the protective frame is erected to three steps or more, diagonal bracing and scissor bracing should be tied on.

[0056] Furthermore, in the above technical solution, the specific steps for constructing a protective area on top of the reinforced area of ​​the protective frame include:

[0057] Install connecting poles at the top of the last row of reinforcing poles in the reinforcement area using movable connecting kits. Connect the remaining reinforcing poles requiring connecting poles by disassembling the connecting kits. Tie bamboo poles to the connecting poles, prioritizing the binding of the two ends before binding the middle poles. After binding, ensure the poles are aligned vertically and horizontally. After pole installation, install the large bamboo horizontal bars in the protection area, ensuring the larger ends of the large bamboo horizontal bars at both ends of the protective frame face outwards. When installing the large horizontal bars on the first step of the protective area, check that the bamboo poles are vertical and secure. The larger ends of the large horizontal bars on the same step should face the same direction, while the larger ends of adjacent steps should face opposite directions to enhance the overall stability of the protective frame. Bind small horizontal bars between the large horizontal bars, with adjacent small horizontal bars facing opposite directions. Bind the small horizontal bars to the poles, with adjacent rows of small horizontal bars bound to different sides of the poles. The length of the small horizontal bars extending beyond the pole should not be less than 300mm.

[0058] The method for binding and installing bamboo is as follows:

[0059] For perpendicular intersections: When bamboo poles intersect perpendicularly, such as at the intersection of bamboo upright stalk 22 and bamboo main horizontal stalk 27, or at the intersection of bamboo upright stalk 22 and bamboo secondary horizontal stalk 28, a horizontal or diagonal cross-lock binding method should be used. The horizontal cross-lock binding method results in less loosening of the rope knots, less settlement of the horizontal stalks, and better overall effectiveness. When binding, the steel wire should be tightened to prevent the bamboo from loosening, but not excessively tightened to avoid breaking or damaging the wire.

[0060] Bamboo splicing: Bamboo splicing adopts the straight-knot binding method, with a joint length of not less than 1.5m and not less than 3 knots, one at each end and one in the middle, and the knots are 0.15m away from the pole end. The splice must be prevented from bending or loosening, so as not to affect the overall stability of the protective frame and the local stress condition.

[0061] Furthermore, in the above technical solution, after the protective area is installed, a safety net should be erected on the top of the protective area, and an anchor plate should be set on the ground at the back end of the protective frame. A steel cable should be wrapped and fixed on the anchor plate, and the other end of the steel cable should be fixedly connected to the bamboo crossbar of the protective area to fix the protective area against the wind.

[0062] The safety netting must be securely tied to the uprights and horizontal bars of the protected area, with a tying interval of no less than 0.3m. Warning signs must be hung on the side of the scaffold facing the construction site. All warning signs must be securely and reliably installed; the steel pipes and bamboo of the scaffold must be painted with yellow warning paint.
