[0049] The following describes in detail the specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and understanding the present invention, and are not used to limit the present invention.

[0050] The outer tower body device, tower body and tower crane of the present invention will be described below with reference to the accompanying drawings.

[0051] Such as Figure 1 andFigure 5 As shown, the present invention provides an outer tower body device, wherein the outer tower body device includes:

[0052] An outer tower body 100, which is disposed around the outside of an inner tower body 200 and includes a base tower body section 110 and an additional story tower body section 120. The lower end of the base tower body section 110 is connected to an outer tower body anchor 130. The additional story tower body section 120 is disposed above the base tower body section 110 and is connected to the inner tower body 200. Moreover, the orthographic projection of the cross-section of the additional story tower body section 120 falls within the cross-section of the base tower body section 110, so that the outer tower body 100 is arranged in a pagoda shape.

[0053] When using the above-mentioned outer tower body device, since the outer tower body 100 in the outer tower body device includes a base tower body section 110 and an additional story tower body section 120, the lower end of the base tower body section 110 is connected to the outer tower body anchor 130, the additional story tower body section 120 is disposed above the base tower body section 110 and is connected to the inner tower body 200, and the cross-section projection of the additional story tower body section 120 falls within the cross-section of the base tower body section 110, so that the outer tower body 100 is arranged in a pagoda shape, that is, the cross-section size of the additional story tower body section 120 is smaller than the cross-section size of the base tower body section 110, and the outer tower body 110 has a variable cross-section. Then, the outer tower body 100 can be connected to the foundation through the base tower body section 110 with a larger cross-section size, so that the outer tower body device has higher strength, stiffness and stability. At the same time, the outer tower body 100 can also reduce the average cross-section size of the entire outer tower body 100 through the additional story tower body section 120 with a smaller cross-section size, thereby reducing the manufacturing cost and significantly improving the economy.

[0054] Specifically, the number of the additional story tower body sections 120 includes but is not limited to one. When the number of the additional story tower body sections 120 is at least two, at least two additional story tower body sections 120 are arranged in sequence from bottom to top, and the orthographic projection of the cross-section of the upper additional story tower body section 120 among two adjacent additional story tower body sections 120 falls within the cross-section of the lower additional story tower body section 120, so that the outer tower body 100 is arranged in a multi-story pagoda shape, that is, the cross-section sizes of at least two additional story tower body sections 120 can be set to be the same or different, and the cross-section size of the upper additional story tower body section 120 can be smaller than the cross-section size of the lower additional story tower body section 120.

[0055] See Figure 1 and Figure 2 and Figure 5 and Figure 6, in an embodiment of the present invention, the outer tower body 100 further includes a pagoda connection section 140. A first connection portion 147 is formed on the lower side of the pagoda connection section 140, and the first connection portion 147 can be detachably connected to the upper end of the base tower body section 110. A second connection portion 148 is formed on the upper side of the pagoda connection section 140, and the second connection portion 148 can be detachably connected to the lower end of the additional floor tower body section 120. A third connection portion 149 detachably connected to the inner tower body 200 is formed inside the pagoda connection section 140. That is, by adding the first connection portion 147, the second connection portion 148, and the third connection portion 149, it is convenient for the pagoda connection section 140 to establish connections with the base tower body section 110, the additional floor tower body section 120, and the inner tower body 200 respectively. With such a setting, the supporting effect of the outer tower body 100 on the inner tower body 200 can be further improved. Specifically, the pagoda connection section 140 can also be arranged between two additional floor tower body sections 120 with inconsistent cross-sectional dimensions.

[0056] In an embodiment of the present invention, the pagoda connection section 140 includes a pagoda section frame 141 and pagoda section diagonal inclined beams 142. The pagoda section frame 141 surrounds the outside of the inner tower body 200, and the pagoda section diagonal inclined beams 142 are connected to the pagoda section frame 141. Moreover, the main chords of the base tower body section 110, the additional floor tower body section 120, and the inner tower body 200 are all located in the extending direction of the pagoda section diagonal inclined beams 142. Specifically, the pagoda section diagonal inclined beams 142 extend linearly, that is, the main chords of the adjacent base tower body section 110 and additional floor tower body section 120, and the main chord of the inner tower body 200 can be projected onto the same straight line. The first connection portion 147, the second connection portion 148, and the third connection portion 149 are sequentially arranged on the extending path of the pagoda section diagonal inclined beams 142 to be detachably connected to the corresponding main chords respectively one by one. That is, the pagoda connection section 140 can be connected to the main chords of two tower body sections with variable cross-sections up and down and the inner tower body 200 respectively, so that the local stiffness is improved, and the load of the inner tower body 200 can be transmitted to the outer tower body 100. In addition, the setting of the pagoda section diagonal inclined beams 142, compared with setting a connection beam perpendicular to and connected to the horizontal web member of the inner tower body 200 on the pagoda section frame 141, on the basis of ensuring a reasonable length, the design of the pagoda section diagonal inclined beams 142 can reduce the corresponding cross-sectional dimension of the first tower body section above the pagoda connection section 140.

[0057] Specifically, the first connecting portion 147, the second connecting portion 148, and the third connecting portion 149 may be disposed on the extension path of the diagonal inclined beam 142 of the pagoda section. However, this does not mean that the first connecting portion 147, the second connecting portion 148, and the third connecting portion 149 must be connected to the diagonal inclined beam 142 of the pagoda section. They may also be selectively disposed on the pagoda section frame 141. At this time, the diagonal inclined beam 142 of the pagoda section can play a role in supporting and strengthening the corresponding connecting portion. More specifically, the detachable connection form between the first connecting portion 147 and the upper end of the lower tower body section, and the detachable connection form between the second connecting portion 148 and the lower end of the upper tower body section can be set to adopt a suitable main chord joint connection form, including but not limited to tenon type, fish tail plate type, bolt type, etc.

[0058] See Figures 1 to 4, in the first embodiment of the present invention, the pagoda section framework 141 includes a first framework 143 and a second framework 144 disposed inside the first framework 143. The cross-sectional shape of the first framework 143 is the same as that of the underlying basic tower section 110, and both can be square cross-sectional shapes of the same size, specifically formed by four first straight rods connected end to end in sequence. The cross-sectional shape of the second framework 144 is the same as that of the upper additional tower section 120, and both can be square cross-sectional shapes of the same size, specifically formed by four second straight rods connected end to end in sequence. Since the second framework 144 is disposed inside the first framework 143, the square cross-sectional size of the second framework 144 is smaller than that of the first framework 143. The diagonal inclined beam 142 of the pagoda section connects the corresponding corner positions of the first framework 143 and the second framework 144 and extends into the main chord of the inner tower 200. A first connecting portion 147 is provided at the corner position of the first framework 143. Further, the four corner positions of the first framework 143 are disposed opposite to the upper ends of the four main chords of the underlying tower section. The four corner positions of the first framework 143 are each provided with a first connecting portion 147 at the lower side, and the four first connecting portions 147 can be respectively connected to the four main chords of the underlying tower section in a one-to-one correspondence. Specifically, the first connecting portion 147 can be inserted or sleeved on the corresponding main chord. At the same time, a second connecting portion 148 is provided at the corner position of the second framework 144. Further, the four corner positions of the second framework 144 are disposed opposite to the lower ends of the four main chords of the upper tower section. The four corner positions of the second framework 144 are each provided with a second connecting portion 148 at the upper side, and the four second connecting portions 148 can be respectively connected to the four main chords of the upper tower section in a one-to-one correspondence. Specifically, the second connecting portion 148 can be inserted or sleeved on the corresponding main chord. Through the settings of the first framework 143 and the second framework 144, the strength of the pagoda section framework 141 can be improved. In addition, a third connecting portion 149 is provided at one end of the diagonal inclined beam 142 of the pagoda section extending into the main chord of the inner tower 200, and the third connecting portion 149 can be detachably connected to the main chord of the inner tower 200 from the side of the main chord of the inner tower 200. That is, the third connecting portion 149 is connected to the main chord of the inner tower 200 in a side connection manner. With such a connection method, the erection of the inner tower 200 and the outer tower 100 can be carried out separately, and the disassembly and assembly are relatively simple. Specifically, the connection method between the third connecting portion 149 and the main chord of the inner tower 200 includes but is not limited to a clamp type, a claw type, and a snap type.

[0059] See Figures 5 to 8, in the second embodiment of the present invention, the pagoda section frame 141 includes a third frame 145 and a fourth frame 146 disposed inside the third frame 145. The cross-sectional shape of the third frame 145 is the same as that of the underlying basic tower section 110, and both can be square cross-sectional shapes of the same size, specifically formed by four third straight rods connected end to end in sequence. The cross-sectional shape of the fourth frame 146 is the same as that of the inner tower 200, and both can be square cross-sectional shapes of the same size, specifically formed by four fourth straight rods connected end to end in sequence. Since the fourth frame 146 is disposed inside the third frame 145, the square cross-sectional size of the fourth frame 146 is smaller than that of the third frame 145. The pagoda section diagonal beam 142 connects the corresponding corner positions of the third frame 145 and the fourth frame 146. A first connecting portion 147 is provided at the corner position of the third frame 145. Further, the four corner positions of the third frame 145 are disposed opposite to the upper ends of the four main chords of the underlying tower section. First connecting portions 147 are provided on the lower sides of the four corner positions of the third frame 145, and the four first connecting portions 147 can be connected to the four main chords of the underlying tower section in one-to-one correspondence. Specifically, the first connecting portion 147 can be inserted or sleeved on the corresponding main chord. At the same time, a second connecting portion 148 is provided on the pagoda section diagonal beam 142. Further, the pagoda section diagonal beam 142 can be provided at the four corner positions of the pagoda section frame 141, and a second connecting portion 148 can be provided on each pagoda section diagonal beam 142. The second connecting portion 148 is located between the first connecting portion 147 and the third connecting portion 149, and the second connecting portion 148 provided on the upper side of the pagoda section diagonal beam 142 is disposed opposite to the lower end of the main chord of the upper tower section so as to be inserted or sleeved on the main chord. In addition, third connecting portions 149 are provided on both the upper and lower sides of the corner positions of the fourth frame 146 to axially dock with the two main chords adjacent to the inner tower 200 in the height direction in one-to-one correspondence. That is, the main chords of the inner tower 200 at the same corner position can be disconnected at the installation height of the fourth frame 146 so that there are two main chords in the upper and lower directions in the height direction. The third connecting portion 149 on the lower side of the fourth frame 146 can be connected to the main chord of the underlying inner tower 200, and the third connecting portion 149 on the upper side of the fourth frame 146 can be connected to the main chord of the upper inner tower 200. Moreover, third connecting portions 149 are provided on both the upper and lower sides of the four corner positions of the fourth frame 146 so that the fourth frame 146 is joined into the inner tower 200 while establishing a connection with the inner tower 200. That is, the third connecting portion 149 is connected to the main chord of the inner tower 200 in an axially docking manner. Such a connection method can make the connection between the pagoda connection section 140 and the inner tower 200 more stable.Specifically, the connection mode between the third connection part 149 and the main chord of the inner tower body 200 can be set to adopt a suitable connection form of the main chord joint, including but not limited to tenon type, fish tail plate type, bolt type, etc.

[0060] In an embodiment of the present invention, the pagoda connection section 140 is arranged in at least two detachable and spliced connections in the circumferential direction. Then the installation of the pagoda connection section 140 can be carried out after the installation of the inner tower body 200, so as to facilitate the disassembly and assembly of the pagoda connection section 140. Specifically, the pagoda connection section 140 is arranged in two detachable and spliced connections in the circumferential direction, and each section is arranged in a U-shaped enclosure, so as to be able to form a frame enclosing the outer side of the inner tower body 200 by splicing. More specifically, the installation of the outer tower body 100 can be carried out after the installation of the inner tower body 200. In order to implement the above installation steps, in addition to the pagoda connection section 140 being arranged in at least two detachable and spliced connections in the circumferential direction in the outer tower body 100, the basic tower body section 110 and the additional floor tower body section 120 should also be arranged in at least two detachable and spliced connections in the circumferential direction.

[0061] See Figures 9 to 12 , and Figures 13 to 16 , in an embodiment of the present invention, the basic tower body section 110 and / or the additional floor tower body section 120 both include an inter-node attachment section 150 and at least two tower section units 160. The at least two tower section units 160 are arranged in sequence from bottom to top. The inter-node attachment section 150 is placed between two adjacent tower section units 160. And a first attachment part 154 is formed on the lower side of the inter-node attachment section 150. The first attachment part 154 can be detachably connected to the upper end of the tower section unit 160 located below among the two adjacent tower section units 160. A second attachment part 155 is formed on the upper side of the inter-node attachment section 150. The second attachment part 155 can be detachably connected to the lower end of the tower section unit 160 located above among the two adjacent tower section units 160. That is, whether it is the basic tower body section 110 or the additional floor tower body section 120, at least two tower section units 160 can be sequentially provided in the height direction, and the butt joint of two adjacent tower section units 160 can be realized by adding the inter-node attachment section 150, and further, the requirements for different heights of the basic tower body section 110 and the additional floor tower body section 120 can be met. Further, the detachable connection form between the first attachment part 154 and the upper end of the tower section unit 160 located below, and the detachable connection form between the second attachment part 155 and the lower end of the tower section unit 160 located above can be set to adopt a suitable connection form of the main chord joint, including but not limited to tenon type, fish tail plate type, bolt type, etc.

[0062] In an embodiment of the present invention, a third attachment portion 156 is further formed inside the inter-node attachment node 150, and the third attachment portion 156 can be detachably connected to the inner tower body 200. By adding the third attachment portion 156, the connection between the outer tower body 100 and the inner tower body 200 can be established through the inter-node attachment node 150.

[0063] See Figures 9 to 12 , in an embodiment of the present invention, the inter-node attachment node 150 includes a first attachment frame 151 and an attachment node diagonal beam 152. The cross-sectional shape of the first attachment frame 151 is set to be the same as that of the tower node unit 160, and both can be square cross-sectional shapes of the same size. Specifically, it can be formed by four fifth straight rods connected end to end in sequence. And the first attachment frame 151 is provided with a second attachment portion 155 and a first attachment portion 154 on the upper and lower sides of the corner positions respectively. Specifically, the first attachment frame 151 is provided with a first attachment portion 154 on the lower side of each of the four corner positions, and the four first attachment portions 154 are respectively connected to the upper ends of the four main chords of the tower node unit 160 located below in one-to-one correspondence. The first attachment frame 151 is provided with a second attachment portion 155 on the upper side of each of the four corner positions, and the four second attachment portions 155 are respectively connected to the lower ends of the four main chords of the tower node unit 160 located above in one-to-one correspondence. The attachment node diagonal beam 152 is connected to the corner position of the first attachment frame 151 and extends towards the main chord of the inner tower body 200. One end of the attachment node diagonal beam 152 extending towards the main chord of the inner tower body 200 is provided with a third attachment portion 156. Among them, the third attachment portion 156 can be detachably connected to the main chord of the inner tower body 200 from the side of the main chord of the inner tower body 200. That is, the third attachment portion 156 is connected to the main chord of the inner tower body 200 in a side connection manner. By setting the connection manner like this, the erection of the inner tower body 200 and the outer tower body 100 can be carried out separately, and the disassembly and assembly are relatively simple. Specifically, the connection manner between the third attachment portion 156 and the main chord of the inner tower body 200 includes but is not limited to a clamp type, a claw type, and a snap type.

[0064] See Figures 13 to 16, in another embodiment of the present invention, the number of the third attachment portions 156 may be two. The two third attachment portions 156 are respectively arranged on the upper and lower sides of the diagonal inclined beam 152 of the attachment section, so as to axially dock with two main chords adjacent to the inner tower body 200 along the height direction respectively. That is, the main chords of the inner tower body 200 at the same corner position can be discontinuously arranged at the installation height of the inter - section attachment section 150, so that there are two main chords in the upper and lower directions along the height direction. The third attachment portion 156 on the lower side of the diagonal inclined beam 152 of the attachment section can be connected to the main chord of the inner tower body 200 located below, and the third attachment portion 156 on the upper side of the diagonal inclined beam 152 of the attachment section can be connected to the main chord of the inner tower body 200 located above. Moreover, the diagonal inclined beams 152 of the attachment section are provided at the four corner positions of the first attachment frame 151, and the third attachment portions 156 are provided on the upper and lower sides of the four diagonal inclined beams 152 of the attachment section, so that the inter - section attachment section 150 is added to the inner tower body 200 while establishing the connection with the inner tower body 200. That is, the third attachment portion 156 is connected to the main chord of the inner tower body 200 by means of axial docking. Such a connection method can make the connection between the inter - section attachment section 150 and the inner tower body 200 more stable. Specifically, the connection method between the inter - section attachment section 150 and the main chord of the inner tower body 200 can be set to adopt a suitable main chord rod joint connection form, including but not limited to tenon - type, fish - tail - plate type and bolt - type, etc. In addition, in this embodiment, the inter - section attachment section 150 may further include a second attachment frame 153 located inside the first attachment frame 151. The cross - sectional shape of the second attachment frame 153 is the same as that of the inner tower body 200, and both can be square cross - sectional shapes of the same size, specifically formed by four sixth straight rods connected end to end in sequence. And the two ends of the diagonal inclined beam 152 of the attachment section are connected to the corner positions of the corresponding first attachment frame 151 and second attachment frame 153 to play a strengthening role.
