Description

Technical Field

[0001] This invention relates to a pressure-bearing sealing structure and its construction method. Background Technology

[0002] Fireproof sealing involves using fireproof sealing materials to seal holes formed when cables or pipes pass through walls or floors. Its purpose is to prevent fire from spreading to areas adjacent to the source of the fire, thus protecting personnel and equipment safety by preventing the fire from spreading through these openings and gaps.

[0003] The basic principle of fireproof sealing is that the sealing material expands and absorbs heat and provides insulation. When exposed to fire, it expands to seal the gaps left by the burning combustibles, preventing the spread of fire and the toxic gases and smoke produced in the fire; it absorbs heat and provides insulation to reduce the temperature of the unexposed side of the penetration, preventing the combustibles on the unexposed side from spontaneously combusting.

[0004] Commonly used fire-stopping methods include cement grouting, rock wool sealing, inorganic fire-stopping material sealing, organic fire-stopping material sealing, fire-resistant bag sealing technology, and fire-resistant ring sealing technology.

[0005] In the past, people used cement grouting to seal vertical shafts, but the solidified sealing layer would burst after a fire, causing the sealing to fail. Furthermore, the grouting process could easily damage the cable sheath, and adding or removing cables after solidification was very difficult.

[0006] Rock wool sealing has advantages such as low cost, simple sealing, and minimal increase in building load, and it also has good fire resistance. However, it cannot completely seal the gaps in cable bundles, nor can it seal the pores between the fibers. As a result, although it has a significant fire-resistant effect in the event of a fire, the smoke that seeps through the pores is still enough to cause suffocation. In addition, the short fibers present during construction are also harmful to human health.

[0007] The inorganic fire-resistant sealant sealing method is essentially the same as the cement grouting method. However, the cured layer of this sealant is fire-resistant and does not crack when exposed to fire, thus effectively providing fire protection. Its disadvantage is that it is not easy to remove.

[0008] Organic fire-retardant sealants offer good sealing effects against both fire and smoke, and are easy to replace. However, because organic fire-retardant sealants are generally quite soft, they are only suitable for sealing small openings, thus limiting their application. Therefore, organic fire-retardant sealants are primarily used for sealing small holes.

[0009] Fire-resistant bags have excellent fire resistance and are easy to seal and disassemble. When exposed to a fire, the filling inside the bag can rapidly expand and seal the flue, effectively preventing the spread of dense smoke and flames. The only drawback is that it cannot block the spread of dense smoke in the early stages of a fire. Harmful dense smoke that penetrates the sealing layer can seriously threaten the lives of people inside the room, causing poisoning, suffocation, or even death. Therefore, its application is also limited.

[0010] This is a state-of-the-art fire-stopping technology specifically designed for plastic pipes. Matching fire collars are available to fit the plastic pipes, making it suitable for fire-stopping holes formed when various plastic pipes pass through walls and floors.

[0011] In practical applications, each individual fire-stopping material has its drawbacks to some extent. Therefore, various fire-stopping materials, such as inorganic fire-stopping materials, organic fire-stopping materials, fire-resistant bags, and fire-resistant rings, are often used in combination to achieve fireproof sealing of internal openings in buildings.

[0012] However, when the construction site is too high, there is a large temperature difference and pressure difference between the two floors, and when there are too many electrical components with high power, an electric field will be formed. This electric field will cause damage to the sealing structure, and the broken sealing material will cause damage to the devices or injury to people. The existing sealing methods cannot solve the above problems, so a new sealing method is needed. Summary of the Invention:

[0013] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pressure-bearing sealing structure and its construction method.

[0014] A pressure-bearing sealing structure includes a flat plate, a column, a sealing material, and a structure for supporting the material. The flat plate has a hole, and the column is placed inside the hole. There is a gap in the horizontal direction between the outer surface of the column and the inner wall of the hole. The structure for supporting the material is placed inside the gap, and the sealing material is provided with material that completely seals the gap between the column and the hole.

[0015] In some special circumstances, some materials cannot be stuck in the holes by their own interference fit. Therefore, the sealing materials needed require a support to be placed in the holes. So the present invention provides a support structure.

[0016] Meanwhile, due to the special construction environment and the excessively high construction location, which is 20 to 25 meters above the ground, construction is extremely inconvenient. Therefore, this invention designs the sealing structure so that construction can be carried out from above the hole.

[0017] To prevent material from falling off, the structure for supporting the material includes multiple hooks and sleeves. The sleeves are thin-walled columns without bottoms or caps. The length of the sleeves in both the horizontal and vertical directions is greater than the length of the holes in both the horizontal and vertical directions. The sleeves are located above the holes, and the holes are located inside the sleeves.

[0018] The hook includes a straight section and a vertical section. One end of the straight section is connected to one end of the vertical section. The other end of the vertical section has a U-shaped bend. The direction of the bend is opposite to the direction of the other end of the straight section. The U-shaped bend notch faces the straight section. The hook is a whole. All the hooks are hung on the side wall of the sleeve through the U-shaped bend. The straight section and the vertical section of the hook are located inside the sleeve. The straight section of the hook forms a support surface.

[0019] The straight section of the hook provides a support surface for the material used to prevent clogging, while the sleeve provides support for the hook. The upper end of the sleeve restricts the hook in the vertical direction, and the side wall of the sleeve restricts the hook in the horizontal direction, making the resulting support surface relatively stable.

[0020] Since an electric field can damage the overall sealing structure, stainless steel mesh can effectively prevent this from happening. In order to prevent the device from corroding, the materials used for sealing include stainless steel mesh and fireproof blanket. The stainless steel mesh and fireproof blanket are stacked on the support surface formed by the straight section of the hook. A cast seal is provided above the fireproof blanket. The combination structure of the fireproof blanket and the cast seal is repeatedly stacked to the sleeve opening. A layer of cast seal that completely covers the sleeve opening is provided above the sleeve opening.

[0021] Finally, the entire hole is sealed tightly with a casting sealant, and the combination of repeated application of anti-corrosion cotton and casting sealant can ensure the sealing performance.

[0022] The sealing materials can be stacked in layers or placed in the supporting structure by adhesive bonding.

[0023] In order to fix the sleeve inside the hole, a fixing frame is provided on the outside of the sleeve, and the sleeve is located inside the fixing frame. The fixing frame includes multiple frames, and each frame is a polygonal structure formed by multiple straight rods. The straight rods are on the same horizontal plane, and the frames are stacked in descending order of size.

[0024] In order to be fixed on the mounting frame, the column is a high-pressure bushing, which is a hollow cylinder with a flange on the outside. The flange is fixed above the uppermost frame.

[0025] For aesthetic purposes, a layer of cast-in-place sealant is installed underneath to completely seal the holes.

[0026] The supporting structure includes multiple supporting plates and sleeves. The supporting plate includes an arc-shaped base plate, an arc-shaped wall plate, and an arc-shaped bending section. The cross-section of the arc-shaped bending section is U-shaped. The height of the base plate is much smaller than its width, and the height of the wall plate is much larger than its width. The outer side of the base plate is connected to the bottom end of the wall plate, and the bending section is connected to the top end of the wall plate. The bending direction is away from the center of the base plate, and the U-shaped bending notch faces the base plate. The supporting plate is a whole.

[0027] The sleeve is a thin-walled column without a bottom or cap. The length of the sleeve in both the horizontal and vertical directions is greater than the length of the hole in both the horizontal and vertical directions. The sleeve is located above the hole, and the hole is located inside the sleeve.

[0028] The support plate is attached to the side of the sleeve through a U-shaped bend. The bottom plate and the wall plate of the support plate are located inside the sleeve, and the bottom plate of the support plate forms a support surface.

[0029] In order to secure the sleeve within the hole and enhance the sealing performance, the structure for supporting the material includes a sleeve, the sleeve including a base plate, the surface of the base plate having a through hole, and the base plate having upward and downward thin-walled structures along the edge of the through hole, the downward thin-walled structure being embedded in the hole of the plate.

[0030] A construction method for a pressure-bearing sealing structure includes the following steps;

[0031] S1: Fix the column in the hole, at which time there is a gap between the column and the inner wall of the hole;

[0032] S2: Dimensions of the measurement gap;

[0033] S3: Select a suitable structure to support the material based on the size of the gap;

[0034] S4: Install a structure within the gap to support the material;

[0035] S5: Select the materials to be used for sealing based on the actual situation;

[0036] S6: Place the material to be used for sealing in the mechanism for supporting the material;

[0037] S7: Completely seal the structure used to support the material;

[0038] S8: Install a truss structure around the structure used to support the material;

[0039] S9: Fix the column to the truss structure.

[0040] Since an electric field can damage the overall sealing structure, stainless steel mesh can effectively prevent this from happening. In order to prevent the device from corroding, the sealing materials include stainless steel mesh, fire blanket and castable sealant. The stainless steel mesh and fire blanket are placed on the structure supporting the material in sequence, and are placed repeatedly in the order of fire blanket and castable sealant, so that the sealing material is finally parallel to the sleeve opening. The stainless steel mesh is only placed at the bottom of the sealing material once, and the sleeve opening is completely sealed with castable sealant.

[0041] To secure the sleeve inside the hole, a fixing frame is included. The fixing frame comprises multiple frames of different sizes. Each frame is a polygonal structure formed by multiple straight rods on the same horizontal plane. The frames of different sizes are stacked in descending order until they are higher than the sleeve opening. The column is fixed to the upper end face of the uppermost frame by flanges set on the outer side wall.

[0042] To prevent material from falling off, the structure for supporting the material includes multiple hooks and sleeves. The sleeves are thin-walled columns without bottoms or caps. The length of the sleeves in the horizontal and vertical directions is greater than the length of the holes in the horizontal and vertical directions. The sleeves are located above the holes, and the holes are located inside the sleeves.

[0043] The hook includes a straight section and a vertical section. One end of the straight section is connected to one end of the vertical section. The other end of the vertical section has a U-shaped bend, the direction of which is opposite to the direction of the other end of the straight section. The U-shaped bend notch faces the straight section. The hook is a whole, and all the hooks are hung on the side wall of the sleeve through the U-shaped bend. The straight section and the vertical section of the hook are located inside the sleeve, and the straight section of the hook forms a support surface.

[0044] The structure 7 for supporting materials includes multiple support plates and sleeves. The support plate includes an arc-shaped base plate, an arc-shaped wall plate, and an arc-shaped bending section. The cross-section of the arc-shaped bending section is U-shaped. The height of the base plate is much smaller than its width, and the height of the wall plate is much larger than its width. The outer side of the base plate is connected to the bottom end of the wall plate, and the bending section is connected to the top end of the wall plate. The bending direction is away from the center of the base plate, and the U-shaped bending notch faces the base plate. The support plate is a whole.

[0045] The sleeve is a thin-walled column without a bottom or cap. The length of the sleeve in both the horizontal and vertical directions is greater than the length of the hole in both the horizontal and vertical directions. The sleeve is located above the hole, and the hole is located inside the sleeve.

[0046] The support plate is attached to the side of the sleeve through a U-shaped bend. The bottom plate and the wall plate of the support plate are located inside the sleeve, and the bottom plate of the support plate forms a support surface.

[0047] In order to secure the sleeve within the hole and enhance the sealing performance, the structure for supporting the material includes a sleeve, the sleeve including a base plate, the surface of the base plate having a through hole, and the base plate having upward and downward thin-walled structures along the edge of the through hole, the downward thin-walled structure being embedded in the hole of the plate.

[0048] Beneficial effects:

[0049] Compared with the prior art, the present invention has a support structure. Due to the presence of an electric field in the special environment, in order to prevent the electric field from damaging the sealing structure, a layer of stainless steel mesh needs to be set at the bottom of the sealing structure. At the same time, due to the possibility of corrosion in underwater operations, fireproof blankets are required, or other special environmental protection needs require the use of other different materials. These materials cannot be stuck in the gaps. The support frame provides support for these materials, solving the problem that some materials cannot be used for sealing.

[0050] At the same time, the presence of the support frame also prevents the sealing material from falling off and injuring the machines or personnel below. Furthermore, compared to a whole support surface, a support surface composed of several individual hooks also has the function of preventing the electric field from damaging the sealing structure.

[0051] In addition, in order to fix the high-pressure bushing in the hole, a fixing device is needed. However, the construction position is too high to fix it below the hole. Therefore, the fixing frame is set above the hole. Since the fixing frame cannot be set on the sealing structure, the frame of the fixing frame is set around the bushing and the fixing frame is connected to the high-pressure bushing for fixing.

[0052] Furthermore, to enhance stability, multiple frames that make up the fixing frame are stacked on top of each other, making the fixing frame higher than the sealing structure. The sealing structure is placed inside the middle of the fixing frame, and the high-pressure bushing is directly fixed to the edge of the uppermost frame through flanges, providing the high-pressure bushing with a supporting force opposite to the direction of gravity.

[0053] Compared to connecting the high-pressure bushing to the frame outside the hole, the connection between the high-pressure bushing and the frame is inclined relative to the horizontal plane, resulting in some loss of the supporting force applied to the high-pressure bushing, and there is also the possibility of stress causing the connection to break. In this invention, the frame is in direct contact with the high-pressure bushing, reducing the length of the lever arm, increasing the utilization rate of the supporting force, and reducing the possibility of stress causing breakage.
