Description

Technical Field

[0001] This invention relates to the field of casting formwork technology, and in particular to a tool for fixing pipes protruding from the roof and its construction method. Background Technology

[0002] Roof pipes are primarily used for drainage, ventilation, and moisture control. They must be installed with waterproof sleeves according to specifications and properly sealed to prevent leakage. For example... Figure 8 As shown, after the roof pipes undergo multiple layers of sealing treatment, concrete needs to be poured on the outermost side to protect the internal sealing structure. The thickness of the concrete pour is generally not less than 50mm.

[0003] Currently, using wooden formwork as concrete piers for pipe root reinforcement is quite common, but it has the following problems: 1. Traditional wooden formwork for reinforcing concrete piers results in low strength and easy deformation of the wooden formwork, leading to poor quality of the concrete piers. 2. The traditional method of fixing the base of the wooden formwork on the outside of the concrete pier is to use rebar anchoring. However, the force of the electric drill is difficult to control, which can easily damage the waterproof membrane and create the risk of roof leakage. 3. Traditional wooden formwork reinforcement of roof pipe concrete piers involves complex procedures, including bending cylindrical formwork, multiple steps such as formwork joint splicing, installation of main and secondary back ribs, and diagonal bracing, resulting in long construction time and low efficiency. 4. If the bent cylindrical template gets damp after use, it may deform or be damaged, making it difficult to reuse the template. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a roof-mounted pipe fixing tool, comprising a pipe body pre-embedded in the roof surface, a protective sleeve sleeved on the outer side of the pipe body, a plurality of lower fixing members provided on the lower side wall of the protective sleeve and fixedly connected to the roof surface, and a plurality of upper fixing members provided on the upper end of the protective sleeve. The lower and upper fixing members secure the protective sleeve, improving stability during pouring.

[0005] The upper fixing component includes a first arc-shaped clamping plate and a second arc-shaped clamping plate. The inner side of the first arc-shaped clamping plate is attached to the upper side wall of the casing, and the side wall of the first arc-shaped clamping plate is provided with a clamping hose clamp. The inner side wall of the second arc-shaped clamping plate is attached to the side wall of the pipe body. The relative position of the upper end of the casing and the pipe body is determined by the first and second arc-shaped clamping plates, in conjunction with the hose clamp.

[0006] Preferably, the lower fixing member includes an angle iron, which is L-shaped and has ground nails inserted through it, the ground nails piercing the roof surface. The angle iron is cut from an angle steel, and the side of the angle iron where the ground nail pierces has a drilled hole.

[0007] Preferably, the length of the ground nail is 50mm. This prevents the ground nail from penetrating through the surface layer of the roof and damaging the underlying waterproof layer.

[0008] Preferably, the upper fixing component further includes a vertical square steel bar, with the first arc-shaped clamping plate fixedly connected to the lower part of the vertical square steel bar. A square steel pipe sleeve is horizontally fixedly connected to the upper end of the vertical square steel bar, and a horizontal square steel bar is inserted through the square steel pipe sleeve. One end of the horizontal square steel bar is fixedly connected to the second arc-shaped clamping plate. The upper fixing component consists of two relatively movable parts, realizing the adjustment of the distance between the first arc-shaped clamping plate and the second arc-shaped clamping plate, that is, satisfying the distance between the casing and the main body of the pipe.

[0009] Preferably, a nut is fixedly connected to the side wall of the square steel tube sleeve, and a bolt is threaded onto the nut. The bolt passes through the square steel tube sleeve and abuts against the horizontal square steel. The nut is fixed by welding, and before welding, holes are drilled in the side wall of the square steel tube sleeve. The horizontal square steel is fixed by tightening the fixing bolt.

[0010] Preferably, the casing is made of PVC pipe. PVC pipe is readily available and comes in a variety of specifications to meet diverse construction needs.

[0011] A construction method for fixing pipes on the roof includes the following steps: Step 1: On the ground above the roof, draw a circular marking line around the center of the main pipe body, with the diameter of the marking line being the same as the diameter of the protective sleeve. This will help to position the lower end of the protective sleeve during installation and allow it to be fitted onto the main pipe body. Step 2: Align the bottom of the casing with the circular marking line, and then install the lower fixing piece. Specifically, one side of the angle iron should be against the side wall of the casing, and the other side should be against the ground. A ground nail should be driven into the side against the ground. The lower fixing piece will fix the bottom of the casing. Step 3: Fix several upper fixing parts to the upper part of the casing with hose clamps. Then, the second arc-shaped clamping plate is attached to the side wall of the pipe body. Adjust the relative position of the horizontal square steel and the square steel pipe sleeve to ensure that the casing and the pipe body are coaxially set. The upper end of the casing is fixed by the upper fixing parts. Step 4: Pour concrete into the inside of the casing; Step 5: When demolding, remove the lower fixing parts, the protective sleeve, the hose clamp, and the upper fixing parts, or leave the protective sleeve intact, meaning the protective sleeve can also serve as part of the protection for the main body of the pipeline.

[0012] The beneficial effects of this invention are as follows: 1. Existing PVC pipes can be used directly to replace wooden formwork, eliminating the difficulty of making wooden formwork, and the smooth inner wall of the PVC pipes ensures the quality of the poured surface.

[0013] 2. The casing is fixed using lower and upper fixing components. The lower fixing components include angle iron and ground nails, while the upper fixing components are secured by a first arc-shaped clamping plate, a second arc-shaped clamping plate, etc., which has the advantages of being simple to use and fix.

[0014] 3. The materials for the lower and upper fixing parts are readily available, such as angle steel and square steel. The selection of the length of the ground nails ensures that they will not damage the waterproof structure of the roof floor. They have the advantages of being easy to manufacture and safe to use.

[0015] 4. This tool is reusable, which can reduce construction costs. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] like Figures 1 to 7As shown, a roof-mounted pipe fixing tool includes a pipe body 5 pre-embedded in the roof surface. For example, the diameter of the pipe body 5 is 100mm. A protective sleeve 2 is sleeved on the outside of the pipe body 5. According to the required pouring thickness of the pipe body 5, the diameter of the protective sleeve 2 is 250mm. Several lower fixing parts 1 are provided on the lower side wall of the protective sleeve 2. The lower fixing parts 1 fix the lower end of the protective sleeve 2 and are fixedly connected to the roof surface. Several upper fixing parts 4 are provided on the upper end of the protective sleeve 2. Similarly, the upper fixing parts 4 fix the upper end of the protective sleeve 2.

[0020] The upper fixing component 4 includes a first arc-shaped clamping plate 41 and a second arc-shaped clamping plate 44. The inner side of the first arc-shaped clamping plate 41 is attached to the upper side wall of the casing 2. All the side walls of the first arc-shaped clamping plates 41 are provided with clamping hose clamps 3. The hose clamps 3 are of the hand-tight type, which is convenient for manual operation. The inner side wall of the second arc-shaped clamping plate 44 is attached to the side wall of the pipe body 5.

[0021] The lower fixing component 1 includes an angle iron 12, which is cut from an angle steel. One side is 50mm long and the other side is 30mm long. A drill hole with a diameter of 4mm is provided on the 30mm long side. The angle iron 12 is L-shaped and a ground nail 11 is inserted through it. The ground nail 11 pierces the roof surface and passes through the drill hole and penetrates the roof surface.

[0022] The length of ground nail 11 is 50mm. The purpose here is to avoid damaging the waterproof structure of the roof surface during the installation of ground nail 11, or to ensure that the depth of ground nail 11 protruding from the roof surface is less than 50mm during actual construction.

[0023] The upper fixing component 4 also includes a vertical square steel 42, which is 100mm long and has a square cross-section with a side length of 20mm. The first arc-shaped clamping plate 41 is fixedly connected to the lower part of the vertical square steel 42 by welding. The upper end of the vertical square steel 42 is horizontally fixedly connected to a square steel tube sleeve 43. Similarly, the vertical square steel 42 and the square steel tube sleeve 43 are welded together. The square steel tube sleeve 43 is 70mm long and has the same cross-sectional profile as the vertical square steel 42. A horizontal square steel 45 is inserted through the square steel tube sleeve 43. The horizontal square steel 45 is 150mm long and has a square cross-section with a side length of 15mm. One end of the horizontal square steel 45 is fixedly connected to the second arc-shaped clamping plate 44 by welding.

[0024] The side wall of the square steel tube sleeve 43 is fixedly connected with a nut 47, and a bolt 46 is threaded onto the nut 47. Both the bolt 46 and the nut 47 are of M10 specification. In addition, before welding the nut 47, a hole needs to be drilled in the middle of the square steel tube sleeve 43 with a hole diameter of not less than 10mm. The bolt 46 passes through the square steel tube sleeve 43 and abuts against the horizontal square steel 45. When the bolt 46 is tightened, the horizontal square steel 45 is fixed.

[0025] The casing 2 is made of PVC pipe, and the edge sealing can be purchased from the market. It also comes in various models and structures to meet a variety of construction needs.

[0026] A construction method for fixing pipes on the roof includes the following steps: Step 1: On the ground above the roof, draw a circular marking line around the center of the pipe body 5, with the diameter of the circular marking line being the same as the diameter of the protective sleeve 2, to position the lower end of the protective sleeve 2, and then fit the protective sleeve 2 onto the pipe body 5. Step 2: Align the bottom of the casing 2 with the circular marking line, and then install the lower fixing part 1. Specifically, one side of the angle iron 12 abuts against the side wall of the casing 2, and the other side is attached to the ground. A ground nail 11 is driven into the side that is attached to the ground. The number of lower fixing parts 1 shall not be less than three. Step 3: Fix several upper fixing parts 4 to the upper part of the casing 2 through hose clamps 3. There should be no less than three upper fixing parts 4. Then, the second arc-shaped clamping plate 44 is attached to the side wall of the pipe body 5. Note that the hose clamp 3 is tightened to the outer side wall of the first arc-shaped clamping plate 41, so that the first arc-shaped clamping plate 41 is tightly attached to and fixed on the casing 2. Adjust the relative position of the horizontal square steel 45 and the square steel sleeve 43 to ensure that the casing 2 and the pipe body 5 are coaxially set, that is, push along the length direction of the horizontal square steel 45. After ensuring that the distance between the casing 2 and the pipe body 5 is correct, it needs to be measured and determined. Then tighten the bolts 46 to clamp and fix the horizontal square steel 45. Step 4: Pour concrete into the interior of casing 2; Step 5: When demolding, remove the lower fixing part 1, the sleeve 2, the hose clamp 3, and the upper fixing part 4, or keep the sleeve 2 without removing it, so that the sleeve 2 also becomes part of the protection of the main body of the pipeline 5.

[0027] Furthermore, the aforementioned components need to be cleaned and rust-proofed after use, so they can be reused.
