Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering structure, in particular to large-span structure, and more particularly to a large-span super-high single-story plant structure system. BACKGROUND

[0002] With the development of industry, the requirements for single-story industrial plants are becoming higher and higher, and the current industrial buildings are developing towards super-large height, large span, large column spacing and large-tonnage cranes. The existing structure forms of single-story plants are mainly bent frame structures and rigid frame structures. Among them, the most commonly used bent frame structure is limited by the fact that its vertical load-bearing members and main lateral force resisting members are steel or concrete columns, so its structural span is usually not more than 30 meters, and the height is usually not more than 30-40 meters. The rigid frame structure will have span change under vertical load due to its rigid connection characteristics of beam-column joints, and it is difficult to meet the use requirements of large-tonnage cranes.

[0003] In order to adapt to the current development level of industrial plants and meet the use requirements of heavy industries such as metallurgy, aerospace and heavy machinery manufacturing for high and large plants, especially to meet the use requirements of large-span super-high single-story plants such as rocket assembly plants, i.e. super-high, super-large and large-tonnage multi-layer cranes, the present application provides a large-span super-high single-story plant structure system and a construction method. SUMMARY

[0004] In view of the problems existing in the prior art, the present application provides a large-span super-high single-story plant structure system for meeting the use requirements of large-span single-story high and large space plants with a span of at least 30-60 m and a height of more than 40 m.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present application is as follows:

[0006] A large-span super-high single-story plant structure system, comprising:

[0007] a concrete core tube, including four large-stiffness concrete core tubes and a plurality of small-stiffness concrete core tubes, wherein the four large-stiffness concrete core tubes are symmetrically arranged in two columns at the corners of the structure system, and the plurality of small-stiffness concrete core tubes are symmetrically arranged in two columns between the large-stiffness concrete core tubes, constituting the main lateral force resisting system of the structure system;

[0008] a steel pipe concrete lattice column and a column inter-support system, wherein the steel pipe concrete lattice columns are symmetrically arranged in two columns between the concrete core tubes, and the column inter-support system connects adjacent small-stiffness concrete core tubes, constituting a supplementary lateral force resisting system of the structure system;

[0009] A concrete frame beam and a prestressed roof system, wherein the concrete frame beam connects the middle of the concrete core tube, the prestressed roof system connects the top of the concrete core tube and the steel pipe concrete lattice column to connect the main lateral system and the supplementary lateral system as a whole.

[0010] In a preferred embodiment, the concrete core tube is a rectangular tube, and the four edges of the rectangle are reinforced concrete shear walls; wherein the high-width ratio of the large-stiffness concrete core tube is 1 / 8-1 / 10, and the high-width ratio of the small-stiffness concrete core tube is 1 / 12-1 / 15.

[0011] In a preferred embodiment, the steel pipe concrete lattice column comprises:

[0012] A small-stiffness steel pipe concrete lattice column, a plurality of the small-stiffness steel pipe concrete lattice columns are symmetrically arranged between the concrete core tubes.

[0013] In a preferred embodiment, the steel pipe concrete lattice column further comprises:

[0014] A large-stiffness steel pipe concrete lattice column, four large-stiffness steel pipe concrete lattice columns are symmetrically arranged at the corners of the two ends of the structural system and correspond to the four large-stiffness concrete core tubes.

[0015] In a preferred embodiment, the inter-columnar bracing system comprises:

[0016] A first inter-columnar bracing, the first inter-columnar bracing connects adjacent small-stiffness concrete core tubes in the middle of the structural system and connects upper and lower layers between the adjacent small-stiffness concrete core tubes.

[0017] In a preferred embodiment, the inter-columnar bracing system further comprises:

[0018] A second inter-columnar bracing, the second inter-columnar bracing connects the large-stiffness steel pipe concrete lattice column at the two ends of the structural system and the corresponding large-stiffness concrete core tube, and connects the upper layer between the large-stiffness steel pipe concrete lattice column and the large-stiffness concrete core tube.

[0019] In a preferred embodiment, the first inter-columnar bracing and the second inter-columnar bracing are both steel braces, and steel plates or anchor bolts are pre-buried when pouring concrete, and the steel braces are welded or bolted to the pre-buried members.

[0020] In a preferred embodiment, the concrete frame beam is connected at 1 / 2 height between the large-stiffness concrete core tube, the small-stiffness concrete core tube, and the small-stiffness steel pipe concrete lattice column in the longitudinal direction, and is connected at 1 / 2 height between the large-stiffness concrete core tubes in the transverse direction, forming a ring closure, so that the concrete core tubes are connected as a whole.

[0021] In a preferred embodiment, it further includes:

[0022] Multiple sets of displacement monitoring and early warning devices are distributed at the top of the steel-concrete lattice column and the middle of the crane beam between the columns to monitor the relative displacement between the column top and the crane beam. When the displacement exceeds the limit, an automatic warning is issued and the crane is locked to ensure the crane's safe operation.

[0023] In a preferred embodiment, the displacement monitoring and early warning device includes a photosensitive signal transmitting / receiving device and a photosensitive signal reflecting plate. The photosensitive signal transmitting / receiving device is arranged at the top of a column or the middle of a crane beam between columns on one side of the structural system, and the photosensitive signal reflecting plate is arranged at the top of a corresponding column or the middle of a crane beam between columns on the other side of the structural system.

[0024] The optical signal reflector is sized according to the desired range of relative displacement to control the relative displacement between the column top and the crane beam.

[0025] When the relative displacement between the column top and the crane beam is within the set allowable range, the photosensitive signal is emitted from the photosensitive signal transmitter / receiver device arranged on one side of the column top or between the crane beams, reflected at the corresponding photosensitive signal reflector on the other side, and then received by the photosensitive signal transmitter / receiver device on the same side. This is the normal working state. When the relative displacement between the column top and the crane beam exceeds the set allowable range, after the photosensitive signal is emitted, the signal is transmitted to the other side but exceeds the range of the photosensitive signal reflector and is not reflected. The photosensitive signal transmitter / receiver device does not receive the photosensitive signal, which is the displacement over-limit state. The displacement over-limit warning is issued and the crane is locked.

[0026] The beneficial effects of this invention compared to the prior art are: This invention provides a large-span, ultra-high single-story factory building structure system for use in single-story factory buildings with high usable space requirements.

[0027] This invention uses four high-stiffness concrete core tubes near the corners of the structure, and multiple low-stiffness concrete core tubes distributed between the high-stiffness concrete core tubes. The two together constitute the main lateral force resisting system of the structure. Steel tube concrete lattice columns and inter-column bracing systems are set between the low-stiffness concrete core tubes as a supplementary lateral force resisting system of the structure, forming a dual lateral force resisting system. This reflects the concept of double-layer protection and improves the redundancy of the structure.

[0028] The present invention connects the concrete core tubes with high-stiffness concrete frame beams and sets up a high-stiffness prestressed roof system to connect the lateral force resisting system into a whole and increase the overall lateral stiffness of the structural system.

[0029] The present invention installs a light-sensing signal transmitting and receiving device between the column top and the middle of the crane beam. When the relative displacement value is too large, it automatically issues a warning and activates the crane locking device.

[0030] It should be understood that the implementation of any embodiment of the present invention does not mean that it will simultaneously possess or achieve multiple or all of the above-mentioned beneficial effects. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0049] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] It should be understood that the terms "comprising / including," "consisting of," or any other variations are intended to cover non-exclusive inclusion, such that a product, apparatus, process, or method that comprises a list of elements includes not only those elements but may also include, where necessary, other elements not expressly listed, or elements inherent to such a product, apparatus, process, or method. Without further limitation, an element defined by the phrases "comprising / including," "consisting of," does not exclude the presence of additional identical elements in the product, apparatus, process, or method that includes said element.

[0051] It should also be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device, component or structure referred to must have a specific orientation, be constructed or operated in a specific orientation, and should not be construed as a limitation of the present invention.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0053] First, it should be noted that in this invention, "large span" refers to a factory building span of at least 30-60m, and "ultra-high" refers to a factory building height exceeding 40m. For ultra-high factory buildings such as rocket vertical assembly plants, the height can typically reach over 100m. For such large-span, ultra-high single-story factory buildings, the existing frame structures and rigid frame structures commonly used in single-story factory buildings are no longer sufficient to meet normal usage requirements.

[0054] Therefore, this invention proposes a large-span, ultra-high single-story factory building structure system. The specific implementation and preferred scheme of the structure system are described in detail below.

[0055] like Figure 1 , Figure 2 As shown in the embodiment of the present invention, a large-span, ultra-high single-story factory building structural system mainly includes: a concrete core tube 1, steel-concrete lattice columns 2 and an inter-column bracing system 3, concrete frame beams 4, and a prestressed roof system 5. This constitutes the large-span, ultra-high single-story factory building structural system. The concrete core tube 1 serves as the main vertical load-bearing component of the structural system and also forms the main lateral resistance system. The steel-concrete lattice columns 2 serve as auxiliary vertical load-bearing components and, together with the inter-column bracing system 3, form a supplementary lateral resistance system. The concrete frame beams 4 and the prestressed roof system 5 connect the entire structural system from the middle and top of the structure, respectively, to increase the overall lateral stiffness of the structural system. This invention uses the concrete core tube, steel-concrete lattice columns, and inter-column bracing system to form a dual lateral resistance system, and improves the overall stiffness of the factory building through the concrete frame beams and prestressed roof system, coordinating structural deformation to meet the stress and deformation requirements of the large-span, ultra-high factory building and ensuring the safety of crane operation.

[0056] Specifically, the concrete core tube 1 includes four high-rigidity concrete core tubes 11 and multiple low-rigidity concrete core tubes 12. The four high-rigidity concrete core tubes 11 are symmetrically arranged in two rows on the left and right at the four corners of the structural system, and the multiple low-rigidity concrete core tubes 12 are symmetrically arranged in two rows on the left and right between the high-rigidity concrete core tubes 11, forming the main lateral resistance system of the structural system. Figure 1 The diagram shows that two small-rigidity concrete core tubes 12 are arranged between the two large-rigidity concrete core tubes 11 on each side. The specific number of small-rigidity concrete core tubes 12 is determined according to the length of the plant.

[0057] Here, the height-to-width ratio of the high-stiffness concrete core tube 11 is 1 / 8-1 / 10, and the height-to-width ratio of the low-stiffness concrete core tube 12 is 1 / 12-1 / 15. Taking a 100m high factory building as an example, the cross-section of the high-stiffness concrete core tube is 10-12m, and the cross-section of the low-stiffness concrete core tube is 6-8m. Both the high-stiffness concrete core tube 11 and the low-stiffness concrete core tube 12 adopt a rectangular (or square) tube body. The four sides of the rectangle can be regarded as reinforced concrete shear walls, thus obtaining greater stiffness.

[0058] For steel-concrete composite lattice column 2, its two left and right rows are symmetrically arranged between the concrete core tubes, such as... Figure 1 As shown, the steel-concrete composite lattice columns 2 are symmetrically arranged in two rows on the left and right sides between adjacent high-stiffness concrete core tubes 11 and low-stiffness concrete core tubes 12, and between adjacent low-stiffness concrete core tubes 12. The inter-column bracing system 3 connects the adjacent low-stiffness concrete core tubes 12, forming a supplementary lateral resistance system for the structural system, as shown. Figure 2 As shown.

[0059] For concrete frame beam 4, it is connected at the middle of the concrete core tube 1 along the height direction, such as... Figure 2 As shown, the prestressed roof system 5 is connected to the top of the concrete core tube 1 and the steel tube concrete lattice column 2 to connect the main lateral resistance system and the supplementary lateral resistance system into a whole.

[0060] In one embodiment of the present invention, the steel-concrete composite lattice column 2 first includes a plurality of low-stiffness steel-concrete composite lattice columns 22. These low-stiffness steel-concrete composite lattice columns 22 are symmetrically arranged in two rows between the concrete core tubes 1, that is, longitudinally arranged between adjacent high-stiffness concrete core tubes 11 and low-stiffness concrete core tubes 12, and between adjacent low-stiffness concrete core tubes 12. For example... Figure 2As shown, three low-stiffness steel-concrete lattice columns 22 are evenly distributed between two adjacent concrete core tubes 1. The reason for adding low-stiffness steel-concrete lattice columns 22 in this embodiment is that the four high-stiffness concrete core tubes 11, concrete frame beams 4, and prestressed roof system 5 of this invention form a rectangular frame with high stiffness. However, for a factory building with a relatively long length (e.g., 200 meters), the stiffness in the middle of the long side will be relatively small. Therefore, low-stiffness concrete core tubes 12 are set between the high-stiffness concrete core tubes 11 to improve the stiffness in the middle. The spacing between the concrete core tubes is generally 50-60 meters, which is too large for the roof truss and crane beam (refer to the column spacing of a typical single-story industrial building, which is about 12 meters). Therefore, low-stiffness steel-concrete lattice columns 22 are set between the low-stiffness concrete core tubes 12 to transfer the vertical load of the roof truss and crane beam. It is easy to understand that since a high-stiffness concrete core tube 11 and a low-stiffness concrete core tube 12 have already been used here, the stiffness of the added lattice column does not need to be too high, so a low-stiffness steel tube concrete lattice column 22 is used.

[0061] In a preferred embodiment, the steel-concrete composite lattice column 2 further includes four high-rigidity steel-concrete composite lattice columns 21, arranged symmetrically in two rows at the corners of both ends of the structural system, i.e., at the corners of the outer sides of the rectangle formed by the core tubes, corresponding to the four high-rigidity concrete core tubes 11. By adding lattice columns at both ends of the concrete core tubes, the stiffness at both ends of the structural system is reduced (the stiffness of the lattice columns is much smaller than that of the core tubes), thus reducing the impact of temperature stress. This can release temperature stress to a certain extent, preventing excessive temperature stress from causing cracks in the concrete core tube structure, which would reduce its stiffness and load-bearing capacity.

[0062] In accordance with the spacing requirements of the concrete core tube, a small-rigidity steel tube concrete lattice column 22 is also arranged between the large-rigidity steel tube concrete lattice column 21 and its corresponding large-rigidity concrete core tube 11.

[0063] It is easy to understand that high-stiffness steel-concrete composite lattice columns 21 are arranged on the outermost sides of both ends of the structural system, while low-stiffness steel-concrete composite lattice columns 22 are arranged inside the structural system. This is because the inter-column bracing will be connected to the high-stiffness steel-concrete composite lattice columns 21 later. The stress on the high-stiffness steel-concrete composite lattice columns 21 is greater than that on the middle lattice columns. Therefore, a larger cross-section and stiffness are required. Hence, the high-stiffness steel-concrete composite lattice columns 21 with larger cross-sections are arranged.

[0064] Here, the height-to-width ratio and cross-sectional dimensions of the high-rigidity steel-concrete lattice column 21 and the low-rigidity steel-concrete lattice column 22 can be consistent with those of the high-rigidity concrete core tube 11 and the low-rigidity concrete core tube 12.

[0065] In one embodiment of the present invention, the column support system 3 firstly includes a first column support 31, which connects adjacent low-stiffness concrete core tubes 12 at the mid-longitudinal position of the structural system, and connects the upper and lower layers between adjacent low-stiffness concrete core tubes 12, that is, the first column support 31 is provided on both the upper and lower layers of the concrete frame beam 4.

[0066] In a preferred embodiment, the inter-column support system 3 further includes a second inter-column support 32, which connects the high-rigidity steel tube concrete lattice columns 21 at both ends of the structural system with the corresponding high-rigidity concrete core tube 11, and connects the upper layer between the high-rigidity steel tube concrete lattice columns 21 and the high-rigidity concrete core tube 11, that is, the second inter-column support 32 is only set on the upper layer of the concrete frame beam 4.

[0067] It should be noted that the first inter-column bracing 31 is arranged in the middle of the longitudinal direction of the structural system, both in the upper and lower layers, while the second inter-column bracing 32 is arranged only in the upper layer at both ends of the structural system. This is because of the stress characteristics of the structure. The lower inter-column bracing is generally arranged in the middle of the temperature zone to reduce the influence of temperature stress (similar to the reason for arranging lattice columns at the edge of the structural system instead of the core tube, both in order to reduce the influence of temperature stress, i.e., to make the stiffness near the ends of the structural system smaller). In addition to being set in the middle, the upper inter-column bracing is also arranged at both ends of the temperature zone, which can effectively transfer the longitudinal wind load transmitted by the transverse horizontal bracing of the roof truss.

[0068] In this embodiment, both the first inter-column support 31 and the second inter-column support 32 are steel supports. Steel plates or anchor bolts are pre-embedded during concrete pouring, and the steel supports are welded or bolted to the pre-embedded parts.

[0069] See also Figure 1 , Figure 2 The concrete frame beam 4 is connected longitudinally at half the height between the high-stiffness concrete core tube 11, the low-stiffness concrete core tube 12 and the low-stiffness steel tube concrete lattice column 22, and transversely at half the height between the high-stiffness concrete core tubes 11, forming a closed ring. This connects the concrete core tubes into a whole, allowing them to jointly bear lateral forces and increase the overall lateral stiffness of the system.

[0070] See also Figure 1 , Figure 3 , Figure 4 as well as Figure 5The prestressed roof system 5 can be a prestressed steel truss, or a prestressed space frame, spacer shell, etc., but it must be a prestressed structure to make the lateral force resisting system a whole and increase its stiffness. This embodiment of the invention takes a prestressed steel truss roof system as an example, consisting of multiple steel trusses 51 and upper and lower chord horizontal supports 52, longitudinal horizontal supports 53, rigid tie rods 54, and flexible tie rods 55 connecting adjacent steel trusses 51. Each steel truss 51 is welded or bolted at both ends to the steel plates embedded in the top of the concrete core tube 1 or steel-concrete lattice columns 2 on both sides, and prestress is applied to the lower chord of the truss, giving the prestressed roof system 5 greater planar stiffness. The upper and lower chord horizontal supports 52 are spaced less than 60m apart and located in positions with high stiffness. The longitudinal horizontal supports 53 are installed along the entire length on both sides. Rigid tie rods 54 are installed at the ridge, and flexible tie rods 55 are used to connect the remaining sections to each steel truss 51. It should be noted that... Figure 5 In the diagram, the prestressed roofing system 5 is only for illustration.

[0071] For example Figure 3 As shown, a schematic diagram of the structural system of an embodiment of the present invention along the horizontal elevation is shown. The super high-rise factory building is usually equipped with three layers of cranes. The steel pipe concrete lattice column 2 is a stepped column, in which a corbel 7 or shoulder beam 8 is provided as a support platform for the upper, middle and lower crane beams 9.

[0072] In addition, such as Figure 4 As shown, the large-span ultra-high single-story factory building structure system of the present invention also includes a displacement monitoring and early warning device 6. Multiple sets of displacement monitoring and early warning devices 6 are distributed at the top of the steel pipe concrete lattice column 2 and the middle of the crane beam 9 between the columns to monitor the relative displacement between the top of the column and the crane beam 9. When the displacement exceeds the limit, an early warning is automatically issued and the crane is locked to ensure the safety of the crane operation.

[0073] Specifically, the displacement monitoring and early warning device 6 includes a light-sensing signal transmitting / receiving device 61 and a light-sensing signal reflecting plate 62. The light-sensing signal transmitting / receiving device 61 is arranged at the top of the steel tube concrete lattice column 2 or the middle of the inter-column crane beam 9 on one side of the structural system. The light-sensing signal transmitting / receiving device 61 can be a single device that has both transmitting and receiving functions, or it can be two devices that are set in the same position. The light-sensing signal reflecting plate 62 is arranged at the top of the corresponding column or the middle of the inter-column crane beam 9 on the other side of the structural system.

[0074] In use, the photosensitive signal reflector 62 is sized according to the desired relative displacement range to control the relative displacement between the column top and the crane beam. When the relative displacement between the column top and the crane beam is within the set allowable range, the photosensitive signal transmitting / receiving device 61 emits an incident photosensitive signal 63 from one side of the column top or the middle of the crane beam between columns. The signal is reflected at the corresponding photosensitive signal reflector 62 on the other side, and the reflected photosensitive signal 64 is received by the photosensitive signal transmitting / receiving device 61 on the same side. This is the normal working state. When the relative displacement between the column top and the crane beam exceeds the set allowable range, after the photosensitive signal is emitted, the incident photosensitive signal 63 is emitted to the other side, but it is outside the range of the photosensitive signal reflector 62 and will not be reflected. That is, the photosensitive signal transmitting / receiving device 61 does not receive the reflected photosensitive signal 64. This is the displacement over-limit state, and an over-limit warning is issued and the crane is locked.

[0075] See Figure 6 The construction method for the large-span, ultra-high single-story factory building structure system provided by this invention includes the following steps:

[0076] The first step is foundation construction;

[0077] The second step is the pouring of concrete core tubes, including the pouring of high-rigidity concrete core tubes and low-rigidity concrete core tubes.

[0078] The third step is the installation of steel-concrete composite lattice columns, including the installation of high-stiffness steel-concrete composite lattice columns and low-stiffness steel-concrete composite lattice columns.

[0079] Step 4: Setting up the inter-column bracing system;

[0080] Step 5: Pouring the concrete frame beams;

[0081] Step 6: Installation of crane beams and other structures;

[0082] Step 7: Installation of the prestressed roofing system;

[0083] Step 8: Installation of displacement monitoring and early warning devices and other auxiliary structures.

[0084] As can be easily understood from the above description, this invention uses a concrete core tube as the main lateral resistance system, and steel-concrete composite lattice columns and high-rigidity inter-column bracing as auxiliary lateral resistance systems. These are connected as a whole by concrete frame beams and a prestressed roof system, increasing the overall rigidity of the structural system and enhancing its safety redundancy to meet the stress and deformation requirements of ultra-high-rise factory buildings. Simultaneously, a displacement monitoring and early warning system is installed to control the relative displacement between the column tops and the crane beams, automatically issuing warnings and locking the crane when the displacement is excessive. This ensures crane safety during extreme conditions such as typhoons and prevents further structural damage. Therefore, compared to typical single-story industrial buildings, the large-span ultra-high single-story factory building structural system proposed in this invention has greater rigidity, vertical bearing capacity, and lateral resistance, meeting the stress, deformation, and safe operation requirements of ultra-high-rise, large-span, large-column-spacing, and large-tonnage crane factory buildings.

[0085] While several specific implementation details are included in the foregoing discussion, these should not be construed as limiting the scope of the invention. Certain features described in the context of individual embodiments may also be implemented in combination in a single implementation. Conversely, various features described in the context of a single implementation may also be implemented individually or in any suitable sub-combination in multiple implementations.

9. The large-span, ultra-high single-story factory building structure system according to claim 1, characterized in that, Also includes: Multiple sets of displacement monitoring and early warning devices are distributed at the top of the steel-concrete lattice column and the middle of the crane beam between the columns to monitor the relative displacement between the column top and the crane beam. When the displacement exceeds the limit, an automatic warning is issued and the crane is locked to ensure the crane's safe operation.

10. The large-span, ultra-high single-story factory building structure system according to claim 9, characterized in that, The displacement monitoring and early warning device includes a photosensitive signal transmitting / receiving device and a photosensitive signal reflecting plate. The photosensitive signal transmitting / receiving device is arranged at the top of a column or the middle of a crane beam between columns on one side of the structural system, and the photosensitive signal reflecting plate is arranged at the top of a corresponding column or the middle of a crane beam between columns on the other side of the structural system. The optical signal reflector is sized according to the desired range of relative displacement to control the relative displacement between the column top and the crane beam. When the relative displacement between the column top and the crane beam is within the set allowable range, the light-sensing signal is emitted from the light-sensing signal transmitter / receiver device arranged on one side of the column top or between the crane beams, reflected at the corresponding light-sensing signal reflector on the other side, and then received by the light-sensing signal transmitter / receiver device on the same side. This is the normal working state. When the relative displacement between the column top and the crane beam exceeds the set allowable range, after the light-sensing signal is emitted, the signal is transmitted to the other side but exceeds the range of the light-sensing signal reflector and is not reflected. The light-sensing signal transmitter / receiver device does not receive the light-sensing signal, which is the displacement over-limit state. An over-limit warning is issued and the crane is locked.
