Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a parapet wall built-in roof insulation layer exhaust pipe installation structure and a construction process. Background Art

[0002] The roof exhaust system belongs to the technical field of roof moisture-proof exhaust. The roof is composed of a reinforced concrete structural layer, an insulation layer, a leveling layer, a waterproof layer, and a protective layer arranged in sequence. The characteristic is that an exhaust passage that runs vertically and horizontally is arranged in the insulation layer, and an exhaust pipe extending out of the roof is connected to the exhaust passage. The outer wall of the extended exhaust pipe is tightly sealed with a waterproof layer and a waterproof additional layer. The above-mentioned roof exhaust system has an exhaust passage that runs vertically and horizontally in the insulation layer, and an exhaust pipe extending out of the roof is connected to the exhaust passage, so that the gas in the insulation layer can be discharged in time, which effectively prevents the roof from cracking and damage due to freezing and swelling of water and pressure of gas, and prolongs the service life of the roof.

[0003] In the prior art, a Chinese patent document with publication number CN112647628B proposes an assembled external parapet panel connection node, including an L-shaped prefabricated external parapet panel and a cast-in-place parapet. A shear bolt is vertically embedded in the upper end of the cast-in-place parapet, one side of the anchor head of the shear bolt is embedded in the cast-in-place parapet, and one end of the bolt rod of the shear bolt extends upward and is set in a vertical hole reserved on the inner side of the roof eaves. Although this technology can effectively solve the problems of the single connection method of the top external panels of the existing parapet, the complex structural measures of the roof panel connectors, the great difficulty of construction, and the low connection efficiency, this technology is consistent with the traditional method in that in the traditional technology, the exhaust duct is usually placed directly inside the insulation layer and fixed by concrete filling. However, this practice has significant defects. Due to the lack of special fixing devices and the thermal expansion and contraction characteristics of the insulation layer and the concrete material itself, the exhaust duct is prone to displacement when subjected to force or temperature changes. This displacement will have an adverse effect on the insulation layer, specifically manifested as physical damage such as cracking and deformation of the insulation layer, thereby shortening its service life. These changes in the insulation layer not only weaken its thermal insulation, heat insulation and moisture-proof properties, thereby reducing the energy efficiency of the building, but also after the insulation layer cracks and deforms, rainwater can easily penetrate into the interior of the floor slab through the cracks, causing leakage problems, further threatening the stability and safety of the building structure.

Then, lay the insulation layer on the top of the first waterproof layer, and open a groove on the top of the insulation layer.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above scheme, by setting a fixing component, the connection pipe and the insulation layer are stabilized, so that the pipe and the insulation layer form a whole, effectively enhancing the structural stability of the insulation layer, preventing the pipe from loosening or shifting to cause damage to the insulation layer, thus avoiding cracks or gaps in the insulation layer, ensuring the integrity of the insulation layer and the long-term thermal insulation effect. At the same time, due to the increased stability of the connection between the pipe and the insulation layer, moisture and water are prevented from entering the insulation layer, keeping the insulation layer dry, ensuring that the insulation effect is not damaged, and improving the moisture-proof performance of the overall structure. A fixing component is set up and an arch clip is used to place it on the outside of the PVC pipe and the galvanized steel pipe. At the same time, a combined fixing method of a conical cylinder and a plug-in column is used to effectively ensure the stability of the pipe and prevent the pipe from shifting or loosening due to external pressure or vibration, thereby avoiding the insulation layer from being affected by external force or pipe deformation. The service life of the insulation layer is extended, especially the clamping design of the conical cylinder and the arc plate. The conical cylinder is used to extrude multiple arc plates, so that the inclined blocks on the side walls of the arc plates are attached to the side walls of the connecting holes, thereby enhancing the overall stability of the structure and making the installation of the PVC pipe and the galvanized steel pipe more stable.

[0022] By arranging an anti-dropping component, by arranging an anti-dropping component inside the conical cylinder, the conical cylinder can be effectively prevented from loosening or falling off after long-term use. When the conical cylinder is connected to the inside of multiple arc plates during use, the rebound spring is used to cause one end of the clamping block to squeeze the inner walls of the multiple arc plates, thereby causing the conical cylinder and the plug-in column to be connected more tightly, thereby ensuring the long-term stability of the fixing component. This design can not only effectively extend the service life of the pipeline installation structure and reduce maintenance costs, but also avoid the problem of cracking of the insulation layer due to the loosening of the conical cylinder.

[0023] By setting a stabilizing component and connecting a fixing cap to the top of the conical tube, the bottom of the fixing cap is brought into contact with the top of the positioning plate, and at the same time, the connection between the conical tube and the positioning plate is tightened, thereby making the arch card more tightly connected to the PVC pipe and the galvanized steel pipe, avoiding the problem of the conical tube being disengaged due to the vibration of the pipeline itself, thereby further improving the stability of the structure, ensuring that the structure can remain stable and unchanged in a complex environment, and through tight connection, the interface between the pipeline and the insulation layer is completely sealed, effectively preventing external moisture or water vapor from entering the insulation layer, and preventing the insulation layer from failing.

One end of the connecting column 10 is fixedly connected to multiple arc plates 11, and one end of the conical cylinder 13 away from the connecting bolt 14 is clamped in the interior of the multiple arc plates 11. The interior of the conical cylinder 13 is provided with an anti-slip assembly for preventing the fixing assembly from slipping off. The anti-slip assembly includes a movable bolt 21 slidably connected to the inside of the conical cylinder 13, and two alignment blocks 22 are fixedly connected to both sides of one end of the movable bolt 21. One side of the alignment block 22 is connected to a clamping block 24 through an axial rotation. A side of the clamping block 24 away from one end of the alignment block 22 is fixedly connected to a rebound spring 46, and one end of the rebound spring 46 away from the clamping block 24 is fixedly connected to one side of the movable bolt 21.

The stabilizing assembly includes a fixing cap 16 connected to the outside of the connecting bolt 14 by a thread, and one side of the fixing cap 16 is fixedly connected to a connecting block 18, and one side of the connecting block 18 is fixedly connected to a clamping cylinder 19, and positioning holes 20 are respectively provided on both sides of the clamping cylinder 19.

[0039] By setting a fixing component, the connection between the pipe and the insulation layer 42 is stabilized, so that the pipe and the insulation layer 42 form a whole, effectively enhancing the structural stability of the insulation layer 42, and preventing the pipe from loosening or shifting to cause damage to the insulation layer 42. In this way, cracks or gaps in the insulation layer 42 can be avoided, ensuring the integrity and long-term thermal insulation effect of the insulation layer 42. At the same time, due to the increased stability of the connection between the pipe and the insulation layer 42, moisture and water can be prevented from entering the insulation layer 42, keeping the insulation layer 42 dry, ensuring that the insulation effect is not damaged, and improving the moisture-proof performance of the overall structure. By setting a fixing component on the outside of the PVC pipe 5 and the galvanized steel pipe 6 The arched card 7 is placed on the outside of the PVC pipe 5 and the galvanized steel pipe 6, and the combined fixing method of the tapered cylinder 13 and the plug-in column 10 is used to effectively ensure the stability of the pipeline and prevent the pipeline from shifting or loosening due to external pressure or vibration, thereby avoiding the thermal insulation performance of the insulation layer 42 being affected by external force or pipeline deformation, and extending the service life of the insulation layer 42. In particular, the card connection design of the tapered cylinder 13 and the arc plate 11 uses the tapered cylinder 13 to extrude multiple arc plates 11, so that the inclined block 12 on the side wall of the arc plate 11 is in contact with the side wall of the connecting hole 9, thereby enhancing the overall stability of the structure and promoting a more stable installation of the PVC pipe 5 and the galvanized steel pipe 6.

[0040] like Figures 1 to 9As shown, a concrete floor 39 is installed inside the roof 1, a brick wall layer is installed inside the parapet 2, a first leveling layer 40 is installed on one side of the concrete floor 39 and the brick wall layer, a first waterproof layer 41 is installed on one side of the first leveling layer 40, an insulation layer 42 is installed on one side of the first waterproof layer 41, a second leveling layer 43 is installed on one side of the insulation layer 42, a second waterproof layer 44 is installed on one side of the second leveling layer 43, a concrete protective layer 45 is installed on one side of the second waterproof layer 44, the galvanized steel pipe 6 and the PVC pipe 5 are both located inside the insulation layer 42, the galvanized steel pipe 6 is U-shaped, the output end of the galvanized steel pipe 6 passes through the side wall of the parapet 2, and the position of the output end of the galvanized steel pipe 6 faces the ground, a protective box 3 is fixedly connected to one side of the parapet 2, a placement slot 4 is provided on the top of the protective box 3, the protective box 3 is installed outside the output end of the galvanized steel pipe 6, the insulation layer 42 A groove is provided on the top, and a plurality of holes are provided inside the thermal insulation layer 42, the first leveling layer 40 and the first waterproof layer 41. The positions of the holes of the thermal insulation layer 42 and the first leveling layer 40 correspond to the positions of the holes of the first waterproof layer 41. The positions of the holes inside the plurality of thermal insulation layers 42, the first leveling layer 40 and the first waterproof layer 41 are respectively located on both sides of the PVC pipe 5 and the galvanized steel pipe 6 and correspond to the positions of the connecting holes 9. The length of the plug-in column 10 and the arc plate 11 is equal to the length of the first leveling layer 40 from the hole of the thermal insulation layer 42, and the size of the holes of the thermal insulation layer 42, the first leveling layer 40 and the first waterproof layer 41 is larger than the diameter of the plug-in column 10. The outer shape of the plurality of arc plates 11 is conical, and one side of the plurality of arc plates 11 is fixedly connected with an inclined block 12. The material of the arc plate 11 is polypropylene, and the specification size of the conical cylinder 13 is larger than the specification size of the cone formed by four arc plates 11.

[0041] By means of the provided plug-in column 10, the curved plate 11 and the conical cylinder 13, when installing the PVC pipe 5 and the galvanized steel pipe 6, firstly, a first leveling layer 40 is laid inside the roof 1 and the parapet 2, and then a first waterproof layer 41 is laid on the top of the first leveling layer 40, and at the same time, an insulation layer 42 is laid on the top of the first waterproof layer 41, and then a groove is opened on the top of the insulation layer 42, and then the PVC pipe 5 and the galvanized steel pipe 6 are respectively placed in the grooves of the insulation layer 42 inside the roof 1 and the parapet 2, and then holes are drilled in the insulation layer 42, the first leveling layer 40 and the first waterproof layer 41 on both sides of the PVC pipe 5 and the galvanized steel pipe 6, and then the plug-in column 10 and a plurality of curved plates 11 are placed inside the holes, and then the arch card 7 is divided into The conical tube 13 is threadedly connected to the inside of the connecting hole 9, and one end of the conical tube 13 is moved toward the middle of the multiple arc plates 11. At this time, the specification size of the conical tube 13 is set to be larger than the specification size of the cone formed by the four arc plates 11. When the conical tube 13 moves toward the inside of the multiple arc plates 11, the multiple arc plates 11 are squeezed away from each other, thereby causing the side walls of the multiple arc plates 11 to fit with the side walls of the hole. At this time, the inclined block 12 on the side wall of the arc plate 11 will be stuck with the side wall of the hole. At this time, the inclined block The outer shape of 12 is inclined, which makes the arc plate 11 fastened to the inside of the hole, and then makes the arch card 7 fixedly installed on the outside of the PVC pipe 5 and the galvanized steel pipe 6. At the same time, when fixing the conical cylinder 13, the bottom of the positioning plate 8 will continuously squeeze the insulation layer 42 to contact the top of the first waterproof layer 41, thereby making the PVC pipe 5 and the galvanized steel pipe 6 to be firmly installed, and at the same time, the insulation layer 42 is tightly fixed, thereby avoiding the shaking of the PVC pipe 5 and the galvanized steel pipe 6, which may cause the insulation layer 42 to break. At the same time, by setting the inclined block 12, the stability of the arc plate 11 can be increased, and the arc plate 11 can be prevented from being stuck inside the hole. At the same time, by setting the material of the arc plate 11 to polypropylene, the arc The curved plate 11 is tough, which facilitates the connection between the conical tube 13 and the curved plate 11. At the same time, by setting the opening of the output end of the galvanized steel pipe 6 to face the ground, it can prevent rainwater from entering the interior of the PVC pipe 5 from the output end of the galvanized steel pipe 6, thereby causing rainwater to damage the insulation layer 42. At the same time, by setting the position of the protective box 3 to be installed on the outside of the output end of the galvanized steel pipe 6 and setting the placement groove 4, the output end of the galvanized steel pipe 6 can be protected, and the problem of external impurities clogging the inside of the galvanized steel pipe 6 and the problem of external objects damaging the output end of the galvanized steel pipe 6 can be avoided. At the same time, it also plays a role in beautifying the output end of the galvanized steel pipe 6, so that a flower pot can be placed on the top of the placement groove 4 for display, thereby beautifying the parapet 2.

[0042] like Figures 6 to 8 As shown, two placement holes 23 are respectively provided on both sides of the conical cylinder 13, the positions of the placement holes 23 correspond to the positions of the blocks 24, and the lengths of the placement holes 23 are equal to the lengths of the blocks 24, one side of the movable bolt 21 is fixedly connected with an extrusion spring 15, one end of the extrusion spring 15 is fixedly connected to the interior of one end of the conical cylinder 13, and the other end of the movable bolt 21 passes through the end of the conical cylinder 13 away from the extrusion spring 15, one side of the fixing cap 16 is fixedly connected with a connecting cylinder 17, the external thread of the connecting cylinder 17 is connected with a protective cover 47, and the height of the protective cover 47 is higher than the length of the movable bolt 21 extending out of one end of the conical cylinder 13.

[0043] By providing an anti-drop component, the anti-drop component is provided inside the conical tube 13, which can effectively prevent the conical tube 13 from loosening or falling off after long-term use. When the conical tube 13 is connected to the inside of the plurality of arc-shaped plates 11 during use, the rebound spring 46 is used to cause one end of the clamping block 24 to squeeze the inner wall of the plurality of arc-shaped plates 11, thereby causing the conical tube 13 to be more tightly connected to the plug-in column 10, thereby ensuring the long-term stability of the fixing component. This design can not only effectively extend the service life of the pipeline installation structure and reduce maintenance costs, At the same time, the problem of cracking of the insulation layer 42 caused by the loosening of the conical tube 13 is avoided. When the conical tube 13 is clamped in the interior of the multiple curved plates 11, since the movable bolt 21 is arranged in the interior of the conical tube 13, when the conical tube 13 moves to the outside of the curved plates 11, the two clamping blocks 24 on both sides of the conical tube 13 will use the rebound effect of the rebound spring 46 to push one end of the clamping block 24 away from the interior of the placement hole 23, and then push one end of the clamping block 24 to contact the inner wall of the multiple curved plates 11, so as to push the conical tube 13 and the multiple curved plates 11 to be connected. The cone tube 13 is stuck to each other, thereby avoiding the problem of loosening of the cone tube 13 and the positioning plate 8 when the cone tube 13 is used for a long time, thereby further increasing the stability of the connection between the PVC tube 5, the galvanized steel tube 6 and the insulation layer 42. At the same time, even if the insulation layer 42 and the concrete have the problem of thermal expansion and contraction in the later stage, the PVC tube 5 and the galvanized steel tube 6 will not be displaced to cause the insulation layer 42 to crack. At the same time, through the provided extrusion spring 15, when the cone tube 13 is disassembled and assembled in the later stage, one end of the movable bolt 21 is pressed to cause the movable bolt 21 to squeeze the extrusion spring 15. The movable bolt 21 moves with the block 24, and at this time, the block 24 is forced to shrink into the inside of the placement hole 23 through the obstruction of one end of the placement hole 23, thereby facilitating the disassembly of the conical cylinder 13. At the same time, by adding a conical cylinder 13 and a protective cover 47 to the outside of the conical cylinder 13, when the conical cylinder 13 is connected to the inside of the arc plate 11, one end of the movable bolt 21 will protrude from one end of the conical cylinder 13. At this time, the protective cover 47 is used to block the movable bolt 21 protruding from the conical cylinder 13, thereby avoiding the problem of accidentally touching the movable bolt 21 during the later pouring of concrete.

[0044] like Figures 1 to 6As shown, the top of the arch card 7 is fixedly connected with a fixing rod 35, the top of the fixing rod 35 is rotatably connected with the second rotating wheel 32, the top of the second rotating wheel 32 is fixedly connected with the third rotating wheel 33 through an axis, one side of the second rotating wheel 32 is connected with the first rotating wheel 31 through a belt transmission, one side of the third rotating wheel 33 is connected with the fourth rotating wheel 38 through a belt transmission, both sides of the fixing rod 35 are fixedly connected with fixing blocks 30, the tops of the two fixing blocks 30 are fixedly connected with fixing cylinders 48, the bottoms of the first rotating wheel 31 and the fourth rotating wheel 38 respectively penetrate the interior of the fixing cylinder 48 and are fixedly connected with a connecting plate 29 through an axis, and the bottoms of the connecting plate 29 away from the fixing block 30 are respectively A positioning cylinder 28 is fixedly connected, and a connecting column 25 is slidably clamped inside the end of the positioning cylinder 28 away from the connecting plate 29. A V-shaped spring piece 26 is fixedly connected to the inside of the connecting column 25 away from the end of the positioning cylinder 28 through an axis. A clamping bolt 27 is fixedly connected to the side of the V-shaped spring piece 26 away from both ends of the axis. The end of the clamping bolt 27 away from the V-shaped spring piece 26 passes through the side wall of the connecting column 25 and is clamped to the positioning hole 20. A fixing plate 36 is fixedly connected to one side of the fixing rod 35. A rotating disk 34 is fixedly connected to the top of the third rotating wheel 33 through an axis. An insert rod 37 is slidably connected to the inside of the rotating disk 34. The end of the insert rod 37 away from the rotating disk 34 is threadedly connected to the inside of the fixing plate 36.

[0045] By setting a stabilizing component, a fixing cap 16 is connected to the top of the conical tube 13, so that the bottom of the fixing cap 16 is in contact with the top of the positioning plate 8, and the connection between the conical tube 13 and the positioning plate 8 is tightened, thereby making the arch card 7 more tightly connected with the PVC pipe 5 and the galvanized steel pipe 6, avoiding the problem of the conical tube 13 being disengaged due to the vibration of the pipeline itself, thereby further improving the stability of the structure, ensuring that the structure can remain stable and unchanged in a complex environment, and through a tight connection, the interface between the pipeline and the insulation layer 42 is completely sealed, effectively preventing external moisture or water vapor from entering the insulation layer 42, preventing the insulation layer 42 from failing, and stabilizing the conical tube 13 and the positioning plate 8. When connecting the positioning plate 8, firstly, the fixing cap 16 is threadedly connected to one end of the connecting bolt 14, and then one end of the connecting column 25 is pulled away from the interior of one end of the positioning tube 28, thereby prompting the end of the connecting column 25 away from the positioning tube 28 to be inserted into the interior of the clamping tube 19. At this time, when one end of the connecting column 25 is inserted into the interior of the clamping tube 19, the V-shaped spring piece 26 inside one end of the connecting column 25 will automatically rebound the clamping bolt 27, prompting one end of the clamping bolt 27 to be inserted into the positioning hole 20 inside the clamping tube 19, thereby prompting the positioning tube 28 to be fixedly connected with the clamping tube 19, and then by rotating the rotating disk 34, the third rotating wheel 33 drives the second rotating wheel 32 to rotate, and at the same time, the first rotating wheel 31 and the fourth rotating wheel 38 are rotated. , thereby prompting the first rotating wheel 31 and the fourth rotating wheel 38 to respectively drive the connecting plates 29 at the top of the positioning plates 8 at both ends of the arch card 7 to rotate, thereby prompting the connecting plates 29 to drive the connecting blocks 18 to rotate, thereby prompting the bottom of the fixing cap 16 to continuously be close to one side of the positioning plate 8, thereby prompting the conical tube 13 to be tightly fixed to the positioning plate 8, thereby avoiding the problem of the conical tube 13 being disengaged due to the vibration of the pipeline itself, and also avoiding the problem of the insulation layer 42 being cracked due to the movement of the pipeline itself. After tightening, the internal plug rod 37 of the rotating disk 34 is threadedly connected to the top of the fixing plate 36, thereby avoiding the problem of the fixing cap 16 being loosened due to the self-rotation of the rotating disk 34 in the later stage. The problem is that by setting the first rotating wheel 31, the rotating disk 34 and the fourth rotating wheel 38, the two fixing caps 16 can be quickly fastened, thereby improving the work efficiency and quickly completing the installation of the pipeline. It should be noted here that before laying the second leveling layer 43 in the later stage, it is necessary to lay an inspection plate on the top of the PVC pipe 5 and the galvanized steel pipe 6, so that when the PVC pipe 5 and the galvanized steel pipe 6 are inspected or replaced in the later stage, the PVC pipe 5 and the galvanized steel pipe 6 can be inspected by opening the inspection plate, and at the same time, it also avoids the damage of the PVC pipe 5 and the galvanized steel pipe 6 and the fixed structure caused by concrete when the second leveling layer 43 is directly laid on the top of the PVC pipe 5 and the galvanized steel pipe 6.

[0046] The embodiment of the present invention also provides a parapet wall built-in roof insulation layer exhaust duct construction process, using the parapet wall built-in roof insulation layer exhaust duct installation structure, including the following steps:

[0047] S1: First, pour the first leveling layer 40 on the concrete floor 39 inside the roof 1 and the brick wall layer inside the parapet 2, and pour the first waterproof layer 41 on the top of the first leveling layer 40, then lay the insulation layer 42 on the top of the first waterproof layer 41, and open a groove on the top of the insulation layer 42, and then place the PVC pipe 5 and the galvanized steel pipe 6 in the grooves inside the insulation layer 42 respectively;

[0048] S2: Then, holes are opened inside the insulation layer 42, the first leveling layer 40 and the first waterproof layer 41, and the plug-in column 10 is placed inside the hole. At this time, the arch clamp 7 is respectively sleeved on the outside of the PVC pipe 5 and the galvanized steel pipe 6, and the bottom of the positioning plate 8 contacts one side of the waterproof layer. At this time, the conical tube 13 is threadedly connected to the inside of the connecting hole 9 and rotated into the inside of the multiple arc plates 11, thereby causing the multiple arc plates 11 to move away from each other, and at the same time, the inclined block 12 is pressed against the side walls of the holes of the first leveling layer 40 and the first waterproof layer 41, thereby causing the PVC pipe 5 and the galvanized steel pipe 6 to be fixedly installed inside the roof 1 and the parapet 2. At the same time, when the conical tube 13 is inserted into the inside of the multiple arc plates 11, the clamp block 24 automatically rebounds by the action of the rebound spring 46, causing one end of the clamp block 24 to contact the side walls of the multiple arc plates 11, thereby causing the conical tube 13 to be clamped inside the multiple arc plates 11;

[0049] S3: Then, the stabilizing component is connected to the top of the conical tube 13, so as to make the connection between the conical tube 13 and the plurality of arc-shaped plates 11 more stable;

[0050] S4: Finally, after the PVC pipe 5 and the galvanized steel pipe 6 are fixed, an inspection plate is laid on the top of the PVC pipe 5 and the galvanized steel pipe 6, and then a second leveling layer 43 is laid around the inspection plate. Then, a second waterproof layer 44 is laid on the second leveling layer 43 and the top of the inspection plate, and at the same time, a concrete protective layer 45 is laid on the top of the second waterproof layer 44, thereby completing the installation of the PVC pipe 5 and the galvanized steel pipe 6.

[0051] Compared with the prior art, the above-mentioned parapet built-in roof insulation layer exhaust duct construction process is adopted: this construction process simplifies the complicated installation steps through a step-by-step operation process, ensuring that the construction personnel can complete the operation in an orderly manner according to the steps, reducing the construction difficulty and time, especially the clamping design of the conical cylinder 13 and the arc plate 11, which greatly simplifies the fixed installation operation of the pipeline and reduces errors and deviations in construction. At the same time, the construction process pays attention to the detail processing of each step, especially in the construction of the waterproof layer and the leveling layer, ensuring the construction quality of each layer, and finally forming a high-quality exhaust duct installation structure, which effectively prevents subsequent problems caused by improper construction. At the same time, since the protection and stability of the structure are taken into consideration during the installation process, the entire exhaust duct installation structure has a long service life, reducing the frequency and difficulty of later maintenance.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
