Therefore, the example term "below..." can include both above and below orientations.

[0035] With the rapid development of the construction industry, the use of string tubes and chutes in engineering has been widely used in various construction projects.

[0036] Concrete drum, also known as concrete placing machine or concrete feeding pipe, is an auxiliary tool widely used in construction. Concrete drum is usually composed of multiple short sections, each of which is a cylindrical object, which can be connected and lengthened with hooks to form a pipe of required length for vertically conveying concrete mixture downward. These short sections can be flexibly combined to meet the construction needs of different heights. The use of concrete drum can effectively reduce the free fall distance of concrete during the pouring process, thereby reducing the occurrence of segregation. By feeding concrete into the formwork through the drum, the flow direction of concrete can be better controlled, which helps to evenly distribute and compact the concrete. In the construction of high-rise buildings, concrete drums can help workers more easily convey concrete to where it is needed, especially when pouring columns or walls.

[0037] Concrete chutes are also indispensable and important equipment in construction. They can help workers transport concrete to designated locations efficiently and accurately. The chute is a trough with a certain slope erected from the side of the foundation pit to the bottom. Concrete flows in the trough by its own weight and is transported to the bottom plate casting work surface. Using a chute to transport concrete is a fast casting method. Chute casting concrete belongs to the non-pumping category, which can greatly reduce the slump of concrete, reduce unit water consumption, and avoid concrete shrinkage. Using a chute to cast concrete is more conducive to the heat dissipation of large-volume concrete in summer construction, and reduces the mold temperature and hydration heat. In addition, chute casting concrete can avoid the blockage of conventional construction pump pipes, has higher work efficiency, and can ensure continuous casting of large-volume concrete.

[0038] However, in some scenarios, due to the dense steel bars on the top of the columns and roof, the concrete pouring height is relatively large. Due to the large inclined length of the string barrel and chute, the string barrel and chute cannot be used in this pouring structure, which reduces the applicability of the concrete delivery tools and affects the quality of the project.

[0039] Figure 1 The structural diagram of the concrete conveying structure according to the embodiment of the present invention is schematically shown. Figure 2 The structure diagram of the concrete conveying structure according to the embodiment of the present invention is schematically shown from another perspective. Figure 1 and 2 As shown, the present invention proposes a concrete conveying structure and a concrete pouring method. The concrete conveying structure in the present invention includes a conveying member 10 and a connecting member. A plurality of conveying members 10 are provided, and the plurality of conveying members 10 are arranged in sequence along the vertical direction. Each conveying member 10 is inclined relative to the vertical direction, and a conveying channel 13 is defined on one side of the conveying member 10. The conveying channel 13 is used to convey concrete. The conveying channels 13 of adjacent conveying members 10 are connected, and adjacent conveying members 10 are connected by connecting members.

[0040] By using the concrete conveying structure in the technical solution, the conveying member 10 and the connecting member are connected in the vertical direction, which is suitable for scenes with a large concrete pouring height such as house construction, thereby improving applicability. In addition, the conveying member 10 is arranged at an angle, which can make the internal composition and structure of the concrete flowing in the conveying channel 13 more uniform, reduce the occurrence of concrete segregation, and improve reliability.

[0041] In some embodiments of the present invention, Figure 1As shown, the conveying member 10 is provided with a plurality of connecting holes 11, which are arranged at intervals, and the connecting holes 11 connect the conveying channel 13 and the side of the conveying member 10 away from the conveying channel 13. In this embodiment, after the concrete conveying structure is placed in the casting template, during the casting process, the concrete will flow from the conveying channel 13 of the conveying member 10 at the highest end of the concrete conveying structure to the conveying channel 13 of the conveying member 10 below in sequence. When the concrete flows to the bottom of the casting template, the concrete will slowly fill the casting template. At this time, the connecting holes 11 can connect the opposite sides of the conveying member 10, that is, connect the concrete in the conveying channel 13 and the concrete on the side of the conveying member 10 away from the conveying channel 13, connect the concrete on the opposite sides of the conveying member 10, so that the concrete on the opposite sides of the conveying member 10 are connected as a whole, thereby improving the cohesion of the concrete, improving the stability of the concrete and the reliability of the overall casting template.

[0042] Specifically, in this embodiment, the shape of the connecting hole 11 can be any shape such as circular, square, triangular, etc. Any shape of the hole that can connect the concrete on the opposite sides of the conveying member 10 belongs to the protection scope of the present invention.

[0043] Specifically, in this embodiment, the arrangement of the multiple connecting holes 11 can be a square arrangement, a trapezoidal arrangement, or a triangular arrangement. The provision of the multiple connecting holes 11 can enable more connections between the concrete in the conveying channel 13 of the conveying member 10 and the concrete on the side of the conveying member 10 away from the conveying channel 13, thereby increasing the cohesion and connection force of the opposite sides of the conveying member 10, and further improving the stability of the concrete in the integral casting template.

[0044] Specifically, in this embodiment, the angle of the conveying member 10 and the on-site construction size are adjusted to facilitate the flow of concrete and to make the concrete in the conveying member 10 and the concrete in the casting template form a whole, thereby avoiding concrete "stratification".

[0045] In some embodiments of the present invention, Figure 1 As shown, the conveying structure also includes a guide member 12, which is arranged on the side of the conveying member 10 away from the guide channel. There are multiple guide members 12, each of which corresponds to the position of a connecting hole 11. The guide members 12 enclose a first space, and the first end of the first space is connected to the connecting hole 11, and the second end of the first space is arranged toward the high end of the conveying member 10 along the conveying direction.

[0046] In this embodiment, if Figure 1As shown, each guide member 12 is covered at a connecting hole 11. When the concrete of the pouring operation flows to the connecting hole 11, the guide member 12 can block the concrete flowing through the connecting hole 11 to a certain extent, ensuring that most of the concrete flows from the conveying channel 13 to the adjacent lower-end conveying channel 13, and most of the concrete will not flow out of the conveying channel 13 from the connecting hole 11. The concrete flowing downward from the conveying channel 13 in sequence will reduce the occurrence of segregation, while the concrete flowing out of the connecting hole 11 will fall vertically and cause segregation. Therefore, the guide member 12 can ensure that the concrete that finally fills the casting formwork is connected on the opposite sides of the conveying member 10, and prevent the concrete from flowing out of the connecting hole 11 when it starts to flow downward to the greatest extent, thereby improving reliability, so that the concrete conveying structure of the present invention can not only ensure the connection of the concrete that finally fills the casting formwork conveying member 10 on the opposite sides, but also reduce the concrete from flowing out of the connecting hole 11 when the concrete conveying structure flows from top to bottom.

[0047] Specifically, in this embodiment, if Figure 1 As shown, the guide member 12 is a guide plate, which is bent, and the bending direction of the guide plate is set toward the connecting hole 11. The guide plate encloses a first space, which can make the concrete passing through the connecting hole 11 first contact with the inner wall surface of the guide plate, and then play a blocking role. When the concrete finally slowly fills the casting template, the concrete on the side of the conveying member 10 away from the conveying channel 13 will be connected with the concrete in the conveying channel 13 through the concrete in the first space, so as to achieve the guiding effect of the guide plate and realize the integrated connection of the concrete, thereby improving the stability and reliability of the concrete in the casting template.

[0048] Specifically, in this embodiment, the second end of the first space is arranged toward the high end of the concrete conveying structure, so that the concrete passing through the connecting hole 11 can flow upward, but due to gravity, the flow of concrete can be hindered, further preventing the concrete from flowing out of the connecting hole 11, causing the outflowing concrete to segregate.

[0049] Specifically, concrete segregation refers to the phenomenon that the cohesive force between the constituent materials of the concrete mixture is insufficient to resist the sinking of coarse aggregate, resulting in uneven composition and structure inside the concrete. Specifically, it manifests as the separation of aggregates and cement paste in the concrete, with the aggregates deposited at the bottom and the cement paste floating on the surface, causing quality defects such as honeycombs, rough surfaces, and weak interlayers to appear after the concrete hardens. In this embodiment, flowing on the conveying channel 13 can effectively reduce the free fall distance of the concrete during the pouring process, and the concrete flowing out of the connecting hole 11 will produce segregation due to the free fall motion.

[0050] Furthermore, in other embodiments of the present invention, the guide member 12 may also be a guide pipe, which is arranged on the conveying member 10, with one end of the guide pipe connected to the connecting hole 11, and the other end of the guide pipe arranged toward the high end of the conveying member 10 along the conveying direction. Similarly, the concrete in the conveying channel 13 in the conveying member 10 can first contact the inner wall surface of the connecting pipe when flowing out of the connecting hole 11, thereby achieving a blocking effect on the concrete. When the concrete slowly fills the casting formwork, the concrete on the outside of the conveying member 10 can be connected to the concrete in the conveying channel 13 through the guide pipe, thereby increasing the cohesion and connection force on the opposite sides of the conveying member 10, and further improving the stability of the concrete in the integral casting formwork.

[0051] Specifically, in this embodiment, the guide pipe can be a straight pipe structure or a curved pipe structure, both of which can realize the connection between the concrete in the conveying channel 13 and the concrete outside the conveying member 10. In theory, the longer the length of the guide pipe along the center line of the guide pipe itself is, the more it can block the concrete flowing out of the conveying channel 13 from the connecting hole 11, wherein the blocking force includes the friction between the concrete and the guide pipe and the gravity of the concrete itself, but the area of ​​the casting template must be taken into consideration, and the end of the guide pipe away from the conveying member 10 cannot be in contact with the casting template. If the contact occurs, the concrete on the side of the conveying member 10 away from the conveying channel 13 cannot enter from the guide pipe, and thus the purpose of connecting the concrete on the opposite sides of the conveying member 10 cannot be realized.

[0052] Specifically, in this embodiment, in order to achieve the lightweight purpose of the concrete conveying structure as much as possible, the specific length of the guide pipe needs to be specifically calculated and analyzed in conjunction with the lightweight problem. The present invention does not specifically limit the size of the guide pipe and the weight of the concrete conveying structure.

[0053] In some embodiments of the present invention, Figure 1As shown, the projection area of ​​the guide member 12 toward the connecting hole 11 is the same as the area of ​​the connecting hole 11. In this embodiment, the above arrangement can ensure that the concrete flowing out of the conveying channel 13 contacts the inner wall surface of the guide member 12, so that the guide member 12 can block the concrete flowing out of the conveying channel 13. When the concrete of the pouring operation flows to the connecting hole 11, the guide member 12 can block the concrete flowing through the connecting hole 11, ensuring that most of the concrete flows from the conveying channel 13 to the adjacent lower end conveying channel 13, and most of the concrete will not flow out of the conveying channel 13 from the connecting hole 11. The concrete flowing downward from the conveying channel 13 will reduce the occurrence of segregation, while the concrete flowing out of the connecting hole 11 will fall vertically and cause the occurrence of segregation. Therefore, the guide member 12 can ensure that the concrete that finally fills the pouring template is connected to the opposite sides of the conveying member 10, and the concrete is prevented from flowing out of the connecting hole 11 to the greatest extent when it starts to flow downward, thereby improving reliability.

[0054] In some embodiments of the present invention, the conveying member 10 includes a conveying plate, which is bent and enclosed to form a conveying channel 13. In this embodiment, the conveying plate is bent, and the bending directions of adjacent conveying plates are opposite, so that multiple conveying plates can be connected end to end in sequence in the vertical direction. The V-shaped structure is suitable for scenes with a large concrete pouring height such as house construction, which improves applicability. The bent conveying plates are enclosed to form a conveying channel 13, which can accommodate concrete. At the same time, since the conveying plates are tilted, it is convenient for the concrete located in the conveying channel 13 to flow. In this embodiment, the tilted setting of the conveying plate refers to the conveying direction of the conveying plate being set at an acute angle to the vertical direction. The opening of the conveying channel 13 of the conveying member 10 below the adjacent conveying member 10 faces the side of the conveying channel 13 of the upper conveying member 10 away from the upper conveying member 10.

[0055] Specifically, in other embodiments of the present invention, the conveying member 10 may also be a conveying pipe, and multiple conveying pipes are connected end to end in the vertical direction, which can also make multiple conveying pipes in a V-shaped structure connected in sequence in the vertical direction, which is suitable for scenes with a large concrete pouring height such as house construction, thereby improving applicability. Two first connecting parts are provided at one end of the conveying pipe along its own conveying direction, and the two first connecting parts are symmetrically arranged about the conveying pipe. Two second connecting parts are provided at the other end of the conveying pipe along its own conveying direction, and the two second connecting parts are symmetrically arranged about the conveying pipe. The first connecting parts and the second connecting parts of two adjacent conveying pipes are respectively buckled and connected by a connecting member.

[0056] Specifically, in this embodiment, adjacent conveying pipes are abutted against each other, and there is no gap at the abutting position, which can prevent the concrete flowing in the conveying channel 13 from flowing out at the conveying pipe connection position, ensuring that the concrete will not flow out from the connection position. The concrete flowing downward from the conveying channel 13 in sequence will reduce the occurrence of segregation, while the concrete flowing out of the connection position will fall vertically and cause segregation. Therefore, the above-mentioned seamless abutment setting improves reliability.

[0057] Furthermore, in other embodiments of the present invention, the conveying member 10 may also be a spiral structure, in which a spiral channel is formed, and multiple spiral structures are spirally connected in the vertical direction. Concrete can flow downward in sequence from the spiral channel in the conveying member 10 at the highest point of the concrete conveying structure, so that the concrete is always in contact with the inner wall surface of the spiral channel during the flow process, thereby reducing the occurrence of segregation.

[0058] Further, in other embodiments of the present invention, the conveying member 10 is provided with a guide portion, which is formed by partially extending a side of the conveying member 10 having the conveying channel 13 toward a side away from the conveying channel 13, and the guide portion encloses a first space, and the top of the first space has an opening. A plurality of guide portions are provided, and the plurality of guide portions are arranged at intervals. The guide portion can block the concrete, and when the concrete fills the casting template, the first space can connect the concrete on the opposite sides of the conveying member 10, thereby improving the connection stability of the concrete.

[0059] Specifically, in this embodiment, the axial directions of the conveying channels 13 of adjacent conveying members 10 are arranged to intersect.

[0060] In some embodiments of the present invention, the angle between the conveying direction and the vertical direction of the conveying channel 13 of each conveying member 10 is the same. In this embodiment, the above-mentioned setting can ensure the same flow speed of concrete when it flows in the conveying channel 13 of each conveying member 10. If the angle between the conveying direction and the vertical direction of the conveying channel 13 of each conveying member 10 is different, the flow speed of concrete in the conveying channel 13 of each conveying member 10 may be different, causing segregation of concrete, resulting in uneven internal composition and structure of concrete, which will make the final stability of concrete after solidification relatively poor, reducing reliability.

[0061] In some embodiments of the present invention, the size of the conveying member 10 along the conveying direction is less than or equal to 2m. In this embodiment, the above arrangement can make the overall size of the conveying member 10 smaller, which is convenient for operators to carry and store the conveying member 10. If the height of the required concrete conveying structure is larger, more conveying members 10 are used to assemble through connectors. If the height of the required concrete conveying structure is smaller, fewer conveying members 10 are used to assemble through connectors.

[0062] Specifically, in this embodiment, the concrete structure adopts an assembly structure of a conveying member 10 and a connecting member, and the conveying member 10 adopts a segmented design. At the same time, the size of each conveying member 10 along the conveying direction does not exceed 2m, which is convenient for carrying and storage, so that the concrete structure can be assembled as needed, thereby improving the disassembly and assembly efficiency.

[0063] In some embodiments of the present invention, the conveying member 10 is a metal member. In this embodiment, the conveying member 10 is a steel member. Since concrete needs to be transferred from the high end of the concrete conveying structure to the low end of the concrete conveying structure, the surface of the conveying member 10 needs to be relatively smooth. As a metal material, the steel member has a relatively smooth surface property, especially high-quality steel, which has fewer surface defects and is easier to achieve a smooth effect. Therefore, the steel member can facilitate the flow of concrete and improve reliability.

[0064] Specifically, in this embodiment, the steel piece has high tensile, compressive, bending and shear strength, can bear large loads, and can withstand large plastic deformation at room temperature and is not easy to break. In addition, the steel piece has a simple production process, low cost, and good atmospheric corrosion resistance, and is a better conveying material in conveying concrete.

[0065] In some embodiments of the present invention, the outer surface of the conveying member 10 is plated with a protective layer. In this embodiment, the protective layer can significantly improve the wear resistance of the conveying member 10, reduce surface damage caused by friction and wear, and thus extend the service life of the conveying member 10. In addition, the protective layer can also protect the surface of the conveying member 10 from oxidation and corrosion, and can effectively isolate the contact between the base metal and the corrosive medium, and maintain the brightness and aesthetics of the appearance of the conveying member 10. By plating the protective layer, direct wear and corrosion on the conveying member 10 can be reduced, thereby reducing the replacement frequency and maintenance costs of the conveying member 10, which helps to reduce the overall cost.

[0066] Specifically, in this embodiment, the protective layer is made of zinc layer material, and the galvanized layer can significantly enhance the corrosion resistance of the steel. The zinc layer is consumed very slowly in the atmosphere, which is one seventeenth of the corrosion rate of steel. The galvanized layer can effectively isolate the contact between the steel and the corrosive medium, thereby extending the service life of the steel. This feature makes the galvanized steel more durable in outdoor and humid environments. A layer of silvery-white zinc layer is formed on the surface of the galvanized steel, which not only has a metallic luster, but also increases the decorativeness. This beautiful appearance makes galvanized steel widely used. In addition, the zinc layer has a high hardness, which can improve the wear resistance of the steel and reduce surface damage and scratches, which is particularly important for the conveying parts 10 that need to withstand concrete friction and wear. Finally, compared with other corrosion-resistant materials such as stainless steel, the cost of galvanized steel is relatively low. Through galvanizing, the material cost can be reduced while maintaining the performance of the steel, and the economic benefits can be improved.

[0067] In some embodiments of the present invention, adjacent conveying members 10 are detachably connected via a connector. In this embodiment, the connector includes a bolt and a nut, one end of the bolt passes through the end of the adjacent conveying member 10 and is matched with the nut to fasten the adjacent conveying member 10.

[0068] Specifically, in this embodiment, the structure of the bolts and nuts is relatively simple, and the adjustment of the fastening force can be achieved by tightening and loosening the nuts, so the entire connection can be disassembled relatively easily. This convenience is particularly suitable for occasions that require regular maintenance or replacement of parts, such as the concrete delivery structure in this embodiment. In addition, since the materials of the bolts and nuts are generally strong and the structure is simple, they can be disassembled and tightened multiple times without damage or loss of the original fastening ability, reducing maintenance costs and improving resource utilization. Finally, bolt connections usually do not require complex welding or riveting processes, and can be installed using simple tools, which makes bolt connections particularly popular in construction and installation connections and improves construction efficiency.

[0069] Specifically, in this embodiment, the inclination angle of the conveying member 10 can be adjusted by the connecting member to the fixing angle of the adjacent conveying member 10. First, the adjacent conveying members 10 are placed at the required inclination angle, and then the adjacent conveying members 10 are fixed by the combination of bolts and nuts, so that the position and angle of the adjacent conveying members 10 can be fixed. In addition, if multiple conveying members 10 need to be assembled, the top two conveying members 10 need to be placed at an angle first, and then fixed, and then the angles of the conveying members 10 downwards are placed and connected and fixed in sequence, so that the assembly of the overall concrete conveying structure can be achieved.

[0070] The present invention describes a concrete conveying structure designed for concrete pouring of tall and large formworks, special-shaped columns, etc. for engineering purposes. The device consists of two parts: a conveying member 10 (a galvanized semicircular steel pipe in this embodiment) and a connecting member. The galvanized semicircular steel pipe is made of high-strength material and specially designed, and can be easily carried, assembled on site, and placed in the pouring formwork in advance to facilitate concrete pouring. The connecting member is made of high-quality steel material, has good rigidity and tensile strength, and can effectively connect the special perforated galvanized steel pipe to prevent the diversion groove from falling off.

[0071] The concrete conveying structure in the present invention is composed of only two accessories, namely, a galvanized semicircular steel pipe and a connector. It has a simple structure and is easy to operate. No special skills are required, and a single person can easily complete the assembly work. Secondly, the galvanized semicircular steel pipe of the present invention adopts a segmented design, and the length of each section of the steel pipe does not exceed 2m, which is convenient for carrying and storing, and the device can be assembled as needed, does not affect the construction progress, and greatly improves the construction efficiency. Thirdly, the galvanized semicircular steel pipe and the connector are light in weight, the material is common, the production is simple, and the price is low, which is very easy to promote and use. Finally, the galvanized semicircular thin-walled steel pipe and the connector are made of high-quality steel materials, which are not only durable, but also harmless to the environment.

[0072] The present invention also proposes a concrete pouring method, such as Figure 3 As shown, the concrete pouring method uses the above-mentioned concrete conveying structure for pouring, and is characterized in that the concrete pouring method includes:

[0073] S1: providing a plurality of conveying members 10;

[0074] S2: Arrange a plurality of conveying members 10 in sequence along the vertical direction, so that each conveying member 10 is inclined relative to the vertical direction, and adjacent conveying members 10 are connected by connecting members;

[0075] S3: Fix the assembled concrete delivery structure in the casting formwork;

[0076] S4: Concrete is delivered into the delivery channel 13 of a delivery member 10 located at the top of the concrete delivery structure to perform concrete pouring.

[0077] By using the concrete pouring method of the present invention, the quality of the conveying member 10 and the connecting member is first checked to ensure that each conveying member 10 and each connecting member are qualified products, and then the qualified multiple conveying members 10 and multiple connecting members are assembled. During the assembly process, first determine that the two conveying members 10 at the highest point are placed at the correct angle, and then fix the two conveying members 10 after the angle is placed through the connecting member, and then the conveying members 10 are placed and connected and fixed in turn in the vertical direction, and finally the assembly of the overall concrete conveying structure is realized. The casting template is a template with an annular structure for holding concrete.

[0078] Then, the operators place the assembled concrete conveying structure in the casting formwork. The fixing method can be adopted by connecting the top of the concrete conveying structure with the top of the casting formwork, thereby realizing the fixation of the concrete conveying structure in the casting formwork, which is convenient for the subsequent concrete pouring.

[0079] In addition, the concrete pouring method of the present invention adopts a method of connecting multiple conveying members 10 and multiple connecting members in a vertical direction, which is suitable for scenes with a large concrete pouring height such as house construction, thereby improving applicability. The conveying members 10 are arranged at an angle, which can make the internal composition and structure of the concrete flowing in the conveying channel 13 more uniform, reduce the occurrence of concrete segregation, and improve reliability.

[0080] Furthermore, in this embodiment, the concrete pouring process is as follows:

[0081] Preparation: Check whether the galvanized semi-circular steel pipes and connectors are intact to ensure the safety and cleanliness of the construction site;

[0082] Assembly and fixation: Use appropriate tools to connect and fix the galvanized semi-circular steel pipe and connectors to ensure they are stable and reliable;

[0083] Install the concrete delivery structure: put the assembled concrete delivery structure into the casting formwork, and ensure that it is firmly fixed in the casting formwork;

[0084] Inspection and acceptance: Check whether the concrete conveying structure is firmly fixed after being fixed to ensure that the project quality meets the requirements.

[0085] Specifically, in this embodiment, when the structural steel bars are densely packed and it is impossible to place the string tube and the chute, the concrete conveying structure can be placed in the casting formwork in advance due to its low cost, and cast integrally with the casting formwork to avoid problems such as segregation of gravel and cement slurry in the concrete due to the high casting height, thereby ensuring that the project quality meets the requirements.

[0086] The concrete pouring method of the present invention uses a concrete conveying structure for pouring, and directly places the concrete conveying structure directly in the pouring template, and directly buries the concrete conveying structure in the pouring template, and the connecting hole 11 can realize the integrated connection of the inner and outer sides of the conveying member 10, thereby improving the stability of the concrete. Among them. The concrete conveying structure is composed of two accessories, a galvanized semicircular steel pipe and a connector. It has a simple structure and is easy to operate. No special skills are required, and a single person can easily complete the assembly work. Secondly, the galvanized semicircular steel pipe of the present invention adopts a segmented design, and the length of each section of the steel pipe does not exceed 2m, which is easy to carry and store, and the device can be assembled as needed, without affecting the construction progress, greatly improving the construction efficiency. Thirdly, the galvanized semicircular steel pipe and the connector are light in weight, common in material, simple to make, and low in price, and are very easy to promote and use. Finally, the galvanized semicircular thin-walled steel pipe and the connector are made of high-quality steel materials, which are not only durable but also harmless to the environment.

[0087] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
