[0001] The invention relates to the technical field of building construction equipment, and in particular to a cylindrical building construction steel platform and a construction method. Background Art

[0002] Aerial building machines are automated construction equipment designed for high-rise buildings or super high-rise buildings. Through aerial operations, it greatly improves construction efficiency, reduces labor and material handling time, and can complete various precision operations in extremely complex construction environments. The emergence of aerial building machines not only promotes the automation process of the construction industry, but also provides a safer and more efficient solution for modern urban construction. Aerial building machines usually consist of a suspended construction platform and a stable frame. The platform can be suspended on the facade of the building and fixedly connected to the frame of the building through high-strength steel cables, steel beams and other structures. The suspended platform provides a space for construction workers and mechanical equipment to work at high altitudes, which can be raised and lowered at any time to meet the construction needs of different floors.

[0003] However, aerial building machines can only be used on buildings with consistent shapes from low to high, and cannot be used for construction work on cylindrical buildings, especially cylindrical buildings with inconsistent upper and lower radii. Summary of the invention

[0004] In view of this, the present invention proposes a cylindrical building construction steel platform and a construction method, wherein an overall supporting frame is set on the ground and surrounds the outside of the building, a top platform is set up on the frame, and a suspension is installed through the top platform, and an enclosed foundation is formed by the suspension. Construction workers carry out construction work through the enclosed foundation. For construction work at different heights, the top platform can be moved by a climbing component to adjust the construction work height, thereby realizing efficient and rapid construction work of the cylindrical building.

[0005] The technical solution of the present invention is achieved in this way:

[0006] On the one hand, the present invention provides a cylindrical building construction steel platform, including a stand, a climbing assembly, a top platform and a suspension, wherein:

[0007] There are multiple stands, which are set on the ground and distributed around the cylindrical building to be constructed;

[0008] The number of climbing assemblies is the same as that of the vertical frames, and they are arranged on each vertical frame in a one-to-one correspondence. All the climbing assemblies are located in the same horizontal plane. The climbing assembly includes two connecting units arranged vertically on the vertical frames.

[0009] The top platform is located at the top of the cylindrical building to be constructed, and is connected to the connection units located above each climbing assembly. The climbing assembly drives the top platform to climb on the stand through the alternating movement of the two connection units;

[0010] The suspension is arranged on the top platform and extends to the outside of the cylindrical building to be constructed. There are multiple suspensions, which surround the cylindrical building to be constructed to form an enclosure foundation, which is used for personnel passage and building construction protection.

[0011] On the basis of the above technical solution, preferably, the top platform includes multiple groups of slides, and the multiple groups of slides are arranged around the bottom of the top platform. The multiple suspensions are respectively slidably arranged on each group of slides, so as to adjust the position of the suspension by sliding on the slide, thereby changing the enclosing diameter and shape of the enclosing base.

[0012] On the basis of the above technical solution, preferably, the suspension includes an inner frame, an outer frame and an inner flap, wherein:

[0017] On the basis of the above technical solution, preferably, the stand comprises a plurality of assembly units, two adjacent assembly units are stacked and fixed in a vertical direction, and each assembly unit is provided with a positioning portion, and the climbing assembly further comprises a driving member and a positioning mechanism, wherein:

[0018] The driving member is arranged between the two connecting units, and the driving member is used to push the two connecting units to change the relative distance between them;

[0019] The positioning mechanism is arranged on the assembly unit, and is used to cooperate with the positioning part to relatively fix the assembly unit and the connecting unit.

[0020] Furthermore, the positioning mechanism includes a rotating block, a limiting portion and a tension spring, wherein:

[0021] The rotating block is rotatably arranged on the connecting unit;

[0022] The limiting part is fixedly arranged on the connecting unit;

[0023] The two ends of the tension spring are fixedly connected to the connecting unit and the rotating block respectively, and the fixing position of the tension spring and the connecting unit is adjustable;

[0024] In a natural state, the tension of the tension spring causes the rotating block to abut against the positioning portion, and when the driving member drives the connecting unit to move upward, the rotating block can rotate and flip over the positioning portion of each assembly unit.

[0025] On the basis of the above technical solution, preferably, the top platform further includes a plurality of Bailey frames and a plurality of connecting members;

[0026] The Bailey frames and the connecting pieces are arranged alternately and enclose a circle;

[0027] The connecting piece comprises two connecting heads, the center lines of the two connecting heads form an angle, and the two connecting heads are respectively connected to the Bailey frames adjacent thereto.

[0028] On the basis of the above technical solution, preferably, it also includes a ring frame, a lifting device and an external wall construction platform, wherein:

[0029] The ring frame is movably arranged on each upright frame, and the ring frame is located below the suspension frame and surrounds the outside of the cylindrical building to be constructed;

[0030] The lifting device is arranged on the connecting unit and has a lifting end, and the lifting end is connected to the ring frame;

[0031] The exterior wall construction platform is movably arranged on the ring frame and can move along the circumference of the ring frame.

[0032] Further preferably, the exterior wall construction platform includes a telescopic platform, a pulley assembly and a lifting device, wherein:

[0034] The pulley assembly is arranged on the telescopic platform, and the telescopic platform is slidably mounted on the ring frame through the pulley assembly;

[0035] The lifting device is arranged on the telescopic platform and is used for lifting building materials or construction workers.

[0036] On the other hand, the present invention provides a cylindrical building construction method, which is implemented based on the above-mentioned cylindrical building construction steel platform, and includes the following steps:

[0037] S1 sets up a pre-buried foundation, and sets up a cylindrical building construction steel platform on the pre-buried foundation;

[0038] S2 divides the two standard layers at the top of the quasi-cylindrical building into a concrete pouring layer and a formwork removal layer from top to bottom, and sets a steel bar binding operation layer between the top of the quasi-cylindrical building and the top platform;

[0039] S3 carries out corresponding construction on the steel bar binding operation layer, concrete pouring layer and formwork removal layer through the enclosed foundation;

[0040] After the corresponding construction of S4 steel bar binding operation layer, concrete pouring layer and formwork removal layer is completed, the climbing assembly drives the top platform to move up to the height of a standard floor;

[0041] S5 repeats steps S2-S4 until the main structure construction of the cylindrical building is completed.

[0042] The cylindrical building construction steel platform and construction method of the present invention have the following beneficial effects compared with the prior art:

[0043] (1) The overall support frame is set on the ground and surrounds the outside of the building. A top platform is set up on the vertical frame, and then a suspension is installed through the top platform. The suspension forms an enclosed foundation. Construction workers carry out construction work through the enclosed foundation. For construction work at different heights, the top platform can be moved by the climbing assembly to adjust the construction work height, thereby realizing efficient and fast construction work of the cylindrical building;

[0044] (2) By setting up multiple sets of slides, the suspension can be adjusted by the slides after the current building height is completed, so as to change the shape or adjust the size to meet the needs of the next floor construction work. The setting of multiple sets of slides also ensures that the adjustable radius of the enclosed foundation has a large range;

[0045] (3) The hoisting device can be used to drive the ring frame to move up and down on the vertical frame so that the ring frame and the exterior wall construction platform can adjust their horizontal heights. The ring frame is equivalent to providing the exterior wall construction platform with a circular track surrounding the main part of the building, so that the exterior wall construction platform can slide on the track and move to different places outside the building. Workers can use the construction platform to carry out exterior wall construction work on the building, such as glass curtain wall installation and tiling. This is especially true for columnar buildings with inconsistent upper and lower radii. This solves the problem that the building is large at the top and small at the bottom, which makes it impossible for facilities such as hanging baskets to send construction workers to a position close to the exterior wall of the building.

[0058] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] like Figure 1-11 As shown, the cylindrical building construction steel platform of the present invention includes a stand 1, a climbing component 2, a top platform 3 and a suspension 4.

[0060] There are multiple frames 1, which are set on the ground and distributed around the cylindrical building to be constructed. The frame 1 is constructed as a whole by a steel structure, and a pre-buried foundation is set on the ground. The frame 1 is fixed on the pre-buried foundation. The frame 1 needs to be set as a highly expandable structure so that it can be expanded in height during construction to adapt to the increasingly high construction heights. In addition, for the pre-buried foundation, it is necessary to first determine the maximum radius of the building body and its center point. Based on its center point, the same number of pre-buried foundations as the frames 1 are set on the ground, and the diameter of the circle where the pre-buried foundations are located needs to be greater than the maximum radius of the building body. For ease of understanding, in this embodiment, the number of frames 1 will be set to six for illustration.

[0061] The number of climbing components 2 is the same as that of the frame 1, that is, six climbing components are set, and are arranged one by one on the six frames 1. The six climbing components 2 are all located in the same horizontal plane. A single climbing component 2 includes two connecting units 21 vertically arranged on the frame 1. The two connecting units 21 are mounted on the outside of the same frame 1 and are arranged up and down in the vertical direction. The climbing component 2 is alternately moved up on the frame 1 through the two connecting units 21 to achieve overall climbing. It should be noted that before the climbing component 2 climbs, it is necessary to expand the height on the frame 1 in advance, and a certain distance needs to be always left between the top of the frame 1 and the climbing component 2.

[0062] The top platform 3 is located at the top of the cylindrical building to be constructed, and is connected to the connection units 21 located above each climbing component 2. The top platform 3 is arranged in a circular shape as a whole, and its diameter is larger than the maximum diameter of the building to be constructed. The top platform 3 is constructed as a whole by steel structural parts. When the climbing component 2 is in motion, the top platform 3 will move synchronously with the connection unit 21 at the top of the climbing component 2. It should be noted that during the climbing process of the top platform 3, the top connection units 21 of each climbing component 2 need to move synchronously. The set top platform 3 can be used to install cement pouring equipment and building material lifting equipment, and can also be used to lift building materials through tower cranes and other equipment in addition to the six embedded foundations.

[0063] The suspension 4 is arranged on the top platform 3 and extends to the outside of the cylindrical building to be constructed. There are multiple suspensions 4, which surround the cylindrical building to be constructed to form an enclosure foundation. The enclosure foundation is used for personnel passage and building construction protection. The suspension 4 can be understood as a bracket foundation suspended at the bottom of the top platform 3, which is preferably a steel structure frame. The suspension 4 is mainly used for personnel to pass and work on each floor of the building, and to set up a protective net around the building. It does not play a major supporting role. Therefore, the enclosure foundation formed can be a non-closed loop setting, which can be selected according to the actual construction situation. For example, it can be a closed loop setting at a smaller building radius and a non-closed loop structure at a larger building radius.

[0064] Taking into account the columnar buildings, which have inconsistent upper and lower radii or even irregular shapes, it is necessary to make the suspension 4 adjustable along the radial direction of the top platform 3 so that the enclosed foundation can adapt to the shape of the building to be constructed. In the present embodiment, the top platform 3 includes a plurality of groups of slides 31, and the plurality of groups of slides 31 are arranged around the bottom of the top platform 3. The plurality of suspensions 4 are respectively slidably arranged on each group of slides 31, so that the position of the suspension 4 can be adjusted by sliding on the slides 31 to change the enclosed diameter and shape of the enclosed foundation. Each group of slides 31 has at least two slides 31. After the suspension 4 is slid and adjusted on the slides 31, it needs to be fixed to the slides 31 and connected to the steel structure of the top platform 3 by fixing parts to ensure the overall stability of the suspension 4.

[0065] By setting up multiple sets of slides 31, the suspension 4 can be movably adjusted through the slides 31 after the construction of the current building height is completed to change the shape or size, thereby adapting to the needs of the next level of construction work. The setting of multiple sets of slides 31 also ensures that the adjustable radius of the enclosed foundation has a larger range.

[0066] In addition, a lifting device such as an electric hoist may be provided on the slide 31 for auxiliary operation, so as to realize the transportation of materials, steel frames and other items on each construction layer.

[0067] In this embodiment, the suspension 4 includes an inner frame 41, an outer frame 42 and an inner flap 43. The end of the inner frame 41 away from the ground is slidably set on the top platform 3, and the end of the outer frame 42 away from the ground is slidably set on the top platform 3 and fixed to the inner frame 41. The outer frame 42 is located on the side of the inner frame 41 away from the cylindrical building to be constructed. A personnel passage is formed between the inner frame 41 and the outer frame 42, and the personnel passages on each of the suspensions 4 are interconnected. The inner flap 43 is set on the side of the outer frame 42 close to the cylindrical building to be constructed.

[0068] The inner frame 41 and the outer frame 42 can be regarded as two square structural surfaces of equal length and unequal width. Since the inner frame 41 is closer to the building, the width of the inner frame 41 is smaller than the outer frame 42, so that there will be no interference between the two adjacent suspension frames 4 when the enclosure foundation is formed. Structural members or ladders need to be set between the inner frame 41 and the outer frame 42 for connection and fixation. The set ladder is located in the formed personnel passage, and the ladder entrance is correspondingly set on the top platform 3. The ladder on the top platform 3 is connected to the ladder in the personnel passage. It should be noted that each time the position of the suspension 4 is adjusted, the connecting ladder between the top platform 3 and the ladder of the personnel passage needs to be readjusted synchronously.

[0069] The inner flap 43 is used to connect the passage formed by the scaffolding on the building with the personnel passage on the suspension 4. The number of flaps 43 is set to multiple and can correspond to different layers of the scaffolding. At the same time, the flap 43 can be configured to be multi-level stacked to adapt to the different distances between the suspension 4 and the scaffolding on the building.

[0070] In this embodiment, a wall attachment 5 is further provided, and the wall attachment 5 is provided between the stand 1 and the cylindrical building to be constructed. The wall attachment 5 is provided in multiple groups, and each group of the wall attachment 5 is located on different horizontal planes.

[0071] Each set of wall attachments 5 is set to twelve, taking a single set of wall attachments 5 as an example. Two wall attachments 5 of the set are set on each stand 1, and the two wall attachments 5 cooperate with the building exterior wall to form a triangular stable structure. A single wall attachment 5 includes embedded parts, adjustable rods and fixed frames, wherein the embedded parts are embedded in the building exterior wall during the building pouring process, the fixed frame is fixed to the stand 1, and the adjustable rod is set between the embedded parts and the fixed frame. The end of the adjustable rod is a threaded adjustable structure, and the two ends are respectively hinged to the fixed frame and the embedded parts to adapt to the errors formed during its installation position and construction.

[0072] In order to realize the climbing action of the climbing assembly 2, the climbing assembly 2 further includes a driving member 22. The driving member 22 is arranged between the two connecting units 21. The driving member 22 is used to push the two connecting units 21 to change the relative distance between them.

[0073] The driving member 22 is preferably a hydraulic cylinder, and two driving members 22 are arranged on each climbing component 2. The two driving members 22 are symmetrically arranged, and their two ends are respectively connected to the two connecting units 21. During the climbing process, the driving member 22 first pushes the top connecting unit 21 to move upward on the frame 1. When the top connecting unit 21 is in place and relatively fixed to the frame 1, the driving member 22 contracts to pull the bottom connecting unit 21 to move upward on the frame 1. This alternating reciprocating process realizes the continuous climbing operation of the climbing component 2 on the frame 1.

[0074] In addition, in order to reduce the resistance of the connection unit 21 when it moves on the stand 1, a plurality of guide pulleys in contact with the stand 1 are provided on the connection unit 21, and the connection unit 21 moves by the rolling friction of the guide pulleys.

[0075] The stand 1 includes a plurality of assembly units 11, and two adjacent assembly units 11 are stacked and fixed in a vertical direction, and each assembly unit 11 is provided with a positioning portion 111. In the present embodiment, the stand 1 includes a plurality of assembly units 11, and two adjacent assembly units 11 are stacked and fixed in a vertical direction. When the stand 1 needs to extend its length, it is only necessary to add a connecting assembly unit 11 at its end. Specifically, the assembly unit 11 is a rectangular frame, and positioning grooves are provided at the four corners of the bottom, and positioning blocks are provided at the four corners of the top. The positioning blocks are conically arranged to be quickly inserted into the positioning grooves, and the upper and lower adjacent assembly units 11 are directly fixed by bolting the frame.

[0076] In this embodiment, the connecting unit 21 further includes a positioning mechanism 23 , and the positioning mechanism 23 is connected to the assembling unit 11 to relatively fix the assembling unit 11 and the connecting unit 21 .

[0077] Specifically, the positioning mechanism 23 includes a rotating block 231, a limiting portion 232 and a tension spring 233. The rotating block 231 is rotatably arranged on the connecting unit 21, the limiting portion 232 is fixedly arranged on the connecting unit 21, and the two ends of the tension spring 233 are respectively fixedly connected to the connecting unit 21 and the rotating block 231, and the fixing position of the tension spring 233 and the connecting unit 21 is adjustable. In the natural state, the tension of the tension spring 233 causes the rotating block 231 to abut against the positioning portion 111 and the limiting portion 232 at the same time, thereby preventing the connecting unit 21 from being moved. The stand 1 slides downward, and when the connecting unit 21 is subjected to an upward pulling force, the driving member 22 drives the connecting unit 21 to move upward. During this process, the rotating block 231 contacts the bottom of the positioning portion 111 and rotates, so that the rotating block 231 can flip from the bottom of the positioning portion 111 to the top of the positioning portion 111. After the rotating block 231 flips over to the top of the positioning portion 111, the tension of the tension spring 233 will also allow the rotating block 231 to quickly reset, thereby preventing the rotating block 231 from sliding from the top of the positioning portion 111.

[0078] Among them, the rotating block 231 is arranged in a triangular shape, so that when it rotates, it can pass through the upper positioning portion 111, and after passing the positioning portion 111, it can be reset to resist the positioning portion 111. The limiting portions 232 can be set to two, and arranged up and down, so that the rotating block 231 can limit its rotation angle through the two limiting portions 232 during the process of rotating to both sides.

[0079] In a specific connection structure, the tension spring 233 is fixedly connected to the connection unit 21 via a clip. By adjusting the fixed position of the clip, the fixed position of the tension spring 233 and the connection unit 21 can be adjusted, thereby changing the direction and magnitude of the tension of the tension spring 233 applied to the rotating block 23, thereby making the climbing device adaptable to different application conditions.

[0080] In order to achieve the climbing positioning of the climbing component 2 on the stand 1, a plurality of positioning portions 111 are arranged on the surrounding side of the assembly unit 11. Since the assembly unit 11 is a rectangular frame structure, it is preferred to arrange a positioning portion 111 around each of the four sides of the assembly unit. Correspondingly, four positioning mechanisms 23 are arranged on a single connecting unit 21.

[0081] As a preferred embodiment, the top platform 3 also includes a plurality of Bailey frames 32 and a plurality of connectors 33. The Bailey frames 32 and the connectors 33 are alternately arranged and enclosed in a circle. The connector 33 includes two connectors 331. The center lines of the two connectors 331 form an angle, and the two connectors 331 are respectively connected to the adjacent Bailey frames 32.

[0082] The Bailey frame 32 is a flat frame structure. The Bailey frame 32 is divided into multiple groups, and the multiple groups of Bailey frames 32 are distributed layer by layer outward along the radius of the top platform 3. After the multiple Bailey frames 32 in the same group are distributed along the circular path, the two adjacent Bailey frames 32 in the same group are inclined to each other. In order to improve the assembly efficiency of the two adjacent Bailey frames 32 in the same group, two connecting heads 331 are arranged on the connecting piece 22. The center lines of the two connecting heads 331 are inclined to each other, and the inclination angle is the same as the angle between the two adjacent Bailey frames 32 in the same group. The two connecting heads 331 are fixed to each other; the connection of the Bailey frames 32 by the connecting piece 2 can not only reduce the number of supporting structures required for the Bailey frames 32, realize the rapid construction of the circular platform, and improve the construction efficiency of the steel platform structure, but also allow the multiple Bailey frames 32 in the same group to be interconnected to improve their bearing capacity.

[0083] As a preferred embodiment, it also includes a ring frame 6, a lifting device 7 and an external wall construction platform 8. The ring frame 6 is movably arranged on each vertical frame 1. The ring frame 6 is located below the suspension 4 and surrounds the outside of the cylindrical building to be constructed. The lifting device 7 is arranged on the connecting unit 21 and has a lifting end. The lifting end is connected to the ring frame 6. The external wall construction platform 8 is movably arranged on the ring frame 6 and can move along the circumference of the ring frame 6.

[0084] By means of the provided lifting device 7, the ring frame 6 can be driven to be lifted and lowered on the vertical frame 1, so that the ring frame 6 and the external wall construction platform 8 can be adjusted in horizontal height. The ring frame 6 is equivalent to providing the external wall construction platform 8 with a circular track surrounding the main part of the building, so that the external wall construction platform 8 can slide on the track and thus be moved to different places outside the building. The workers can use the construction platform 8 to carry out external wall construction operations of the building, such as glass curtain wall installation, tiling and other operations. Especially for columnar buildings with inconsistent upper and lower radii, the problem of the building being larger at the top and smaller at the bottom causing facilities such as hanging baskets to be unable to send construction workers to a position close to the external wall of the building is solved.

[0085] At the same time, the ring frame 6 can also form a ring channel outside the building for construction workers to pass through.

[0086] The lifting device 7 is preferably an electric hoist, which is fixed on the connecting unit 2 and the hook is connected to the ring frame 6.

[0087] Furthermore, the exterior wall construction platform 8 includes a telescopic platform 81, a pulley assembly 82 and a lifting device 83. The telescopic platform 81 is arranged on the ring frame 6 and can be extended and retracted along the radial direction of the ring frame 6. The pulley assembly 82 is arranged on the telescopic platform 81. The telescopic platform 81 is slidably installed on the ring frame 6 through the pulley assembly 82. The lifting device 83 is arranged on the telescopic platform 81 for lifting building materials or construction personnel.

[0088] The telescopic platform 81 is configured as at least a two-stage telescopic structure. This configuration allows the telescopic platform 81 to be extended to the outside of the building's exterior wall through telescoping after the height of the ring frame 6 is adjusted, and then to operate close to the building's exterior wall. The set pulley assembly 82 allows the exterior wall construction platform 8 to slide stably on the ring frame 6. Specifically, the pulley assembly 82 includes at least four upper limiting wheels and at least four lower running wheels. The limiting wheels are used to limit the movement direction of the telescopic platform 81, and the running wheels are used as the main load-bearing. The lifting device can be selected as a winch or a hanging basket or other equipment.

[0089] The cylindrical building construction method of the present invention is implemented based on the above-mentioned cylindrical building construction steel platform, and includes steps S1-S5.

[0090] Step S1: setting up a pre-buried foundation, and erecting a cylindrical building construction steel platform on the pre-buried foundation.

[0091] For the embedded foundation, it is necessary to first determine the maximum radius of the building body and its center. Based on its center, set the same number of embedded foundations as the frame 1 on the ground, and the diameter of the circle where the embedded foundation is located must be larger than the maximum radius of the building body. After the embedded foundation is set, set the climbing component 2, the top platform 3, the suspension 4 and the ring frame 6 in sequence.

[0092] Step S2: Divide the two standard layers at the top of the cylindrical building into a concrete pouring layer and a formwork removal layer from top to bottom, and set a steel bar binding operation layer between the top of the cylindrical building and the top platform 3.

[0093] In this embodiment, it is preferred to construct layer by layer, so the building can be divided into three layers, namely, the steel bar tying operation layer, the concrete pouring layer and the formwork removal layer. The steel bar tying operation layer is used for the steel bar tying operation of the building to provide a foundation for concrete pouring, the concrete pouring layer is used for concrete pouring operations, and the formwork removal layer is used for removing the building formwork after the poured concrete solidifies. It should be noted that scaffolding needs to be set up on these three layers for construction operations, and the scaffolding can be built and dismantled through the enclosed foundation formed by the suspension 4.

[0094] Step S3: Carry out corresponding construction on the steel bar binding operation layer, concrete pouring layer and formwork removal layer through the enclosed foundation.

[0095] In this step, construction is performed on the different working layers divided in step S2 in sequence.

[0096] Step S4: After the corresponding construction of the steel bar binding operation layer, the concrete pouring layer and the formwork removal layer is completed, the climbing component 2 drives the top platform 3 to move up to the height of a standard layer.

[0097] When the upward movement is completed, the original steel bar tying operation layer becomes the concrete pouring layer, the original concrete pouring layer becomes the formwork removal layer, and the standard layer height at the top of the building becomes the steel bar tying operation layer, and the process will return to step S1.

[0098] Step S5: Repeat steps S2-S4 until the main structure of the cylindrical building is completed.

[0099] During the construction process, it is also necessary to carry out construction work on the building's exterior walls through facilities such as the ring frame 6 according to the building's construction conditions. At the same time, the positions of steel structures such as the suspension 4 are adjusted according to the building's appearance.
