The following describes the construction method of the coagulation tower according to the embodiment of the present invention with reference to FIGS. 1 to 4 .

The construction method of the concrete tower according to the embodiment of the present invention comprises the following steps:

S1: build the tower foundation 110 on the ground, and build the tower crane foundation 210 on the tower foundation 110;

S2: Install the tower crane main body 220 on the tower crane foundation 210. The tower crane main body 220 includes a longitudinal truss 221 and a horizontal truss 222. The longitudinal truss 221 is vertically fixed on the tower crane foundation 210, and the horizontal truss 222 is arranged in the horizontal direction and connected to the longitudinal truss 221. On the top, the horizontal truss 222 is provided with a crane that can slide along the horizontal truss 222, and the longitudinal truss 221 is installed up to a first preset height;

S3: Use a crane to hoist the prefabricated parts on the tower foundation 110 to form a ring-shaped tower section 122, the tower section 122 is located on the horizontal side of the tower crane main body 220, and the prefabricated parts are annular or sheet-shaped, when the prefabricated parts are sheet-shaped To hoist a plurality of prefabricated parts to form a ring, the central axis of the tower section 122 is set vertically;

S4: After each tower section 122 is hoisted, another tower section 122 is hoisted upward until the tower main body 120 is formed; wherein, at least one tower section 122 is the arm tower section 121 and the arm tower section 121 The arm structure 230 is connected with the longitudinal truss 221 . in,

In step S4, after completing the hoisting of one arm tower section 121, first install the arm structure 230, and then hoist another tower section 122 above the arm tower section 121; the arm tower section 121 On the upper or the tower section 122 above the arm tower section 121, there is an anchoring device (not shown in the figure) for fixing the prestressed cable (not shown in the figure); each tower section that needs to install the anchoring device After the hoisting of 122 is completed, the prestressed cable is first stretched and fixed between the anchoring device and the tower foundation 110, and then another tower section 122 is hoisted upward.

It should be noted that the construction method of the present invention can be used for tower construction in the thermal power generation field, tower construction in the wind power generation field, and tower construction in the chemical field, and can be used for top installation. The construction of the tower with the power generation device can also be used for the construction of the chimney tower with the open top, and the specific use and application field of the constructed concrete tower 10 are not limited here.

It can be understood that, in the construction method of the present invention, after hoisting a plurality of tower sections 122, one supporting arm tower section 121 can be hoisted, and after hoisting the supporting arm tower section 121, the supporting arm structure 230 is first installed, and then the supporting arm tower section 121 is hoisted. Continue to hoist other tower sections 122, which ensures that every multiple tower sections 122 on the tower body has a support arm structure 230 connected to the longitudinal truss 221, so that the tower main body 120 provides stability to the longitudinal truss 221 structure. Therefore, the stability of the main body 220 of the tower crane during construction is ensured.

In addition, since the arm tower section 121 or the tower section 122 above the arm tower section 121 is provided with an anchoring device for fixing the prestressed cable, and each tower section 122 that needs to install the anchoring device is hoisted After completion, the prestressed cable is first stretched and fixed between the anchoring device and the tower foundation 110, and then another tower section 122 is hoisted upward. Therefore, during the construction process of the tower, the prestressed cables of different lengths are fixed in sections, which greatly ensures the stability of the tower main body 120 during the construction.

In addition, it should be added that the above-mentioned annular tower section 122 does not only mean that the cross section of the tower section 122 is formed as a circular ring, but may also be a polygonal structure such as a quadrangle, a hexagon, or the like. In the same way, the preform is not limited to an arc shape but can also be a flat plate shape.

According to the concrete construction method of the embodiment of the present invention, during the construction process, one arm tower section 121 is hoisted on the plurality of tower sections 122, and after each completion of the hoisting of one arm tower section 121, the arm tower section 121 is installed first. The arm structure 230 is installed, and another tower section 122 is hoisted above the arm tower section 121, so that the tower main body 120 provides a stable support for the longitudinal truss 221 structure, thereby ensuring the stability of the tower crane main body 220 during construction. sex. In addition, each arm tower section 121 or the tower section 122 above the arm tower section 121 is provided with an anchoring device for fixing the prestressed cable. After the tower section 122 that needs to be installed with the anchoring device is hoisted First, the prestressed cable is stretched and fixed between the anchoring device and the tower foundation 110, and then another tower section 122 is hoisted upward, which greatly ensures the stability of the tower main body 120 during construction.

In some embodiments, as shown in FIG. 1 , the arm structure 230 is vertically disposed with two or three lanes. It can be understood that too many supporting arm structures 230 will result in complicated construction, while less supporting arm structures 230 cannot support the main body 220 of the tower crane well. Therefore, the arm structure 230 is provided with two or three lines along the longitudinal truss 221 , which can not only ensure convenient construction, but also ensure the supporting effect of the tower crane main body 220 . Of course, in other embodiments of the present invention, the number of the arm structures 230 may be determined according to the actual height of the concrete tower 10 and the height of the tower crane main body 220, and is not limited to the above range.

In some embodiments, in step S4, each time a plurality of tower sections 122 are assembled, the height of the longitudinal girders 221 is increased once. It can be understood that, during the construction of the concrete tower 10, the height of the longitudinal girders 221 is gradually increased, and is not initially erected higher than the height of the concrete tower 10 to be constructed. In the process of construction, before the addition of the longitudinal truss 221, the lower part has been connected to the arm tower section 121 of the concrete tower 10 through the arm structure 230, which greatly ensures the stability of the longitudinal truss 221. , which ensures the stability of the tower crane 20 .

In some embodiments, as shown in FIG. 2 and FIG. 4 , the outer peripheral wall of the arm tower section 121 is provided with an ear plate 1211, the ear plate 1211 is provided with a matching hole 12111, and the arm structure 230 is connected to the ear plate by bolts on the matching hole 12111 of the plate 1211. It can be understood that the outer peripheral wall of the arm tower section 121 is provided with a lug plate 1211, the lug plate 1211 is provided with a matching hole 12111, the longitudinal truss 221 of the tower crane main body 220 is provided with an arm structure 230, and the arm structure 230 It is connected to the matching hole 12111 of the ear plate 1211 by bolts. The use of bolt connection simplifies the connection structure between the arm structure 230 and the arm tower section 121, reduces the construction cost and improves the construction efficiency. In addition, the tower crane main body 220 includes a horizontal truss 222 and a longitudinal truss 221, and the horizontal truss 222 is arranged in the horizontal direction and is connected to the longitudinal truss 221. Such a structure ensures the structural stability of the tower crane main body 220, and further avoids when the concrete tower is damaged. When the construction height of 10 is too high, the main body 220 of the tower crane is skewed.

In some embodiments, the matching hole 12111 is a long hole, and after the bolt is adjusted in the long hole, it is welded and connected to the lug plate 1211 . It can be understood that in the actual construction process, the connection position of the arm structure 230 and the lug plate 1211 may be deviated. If the matching hole 12111 is only formed in the same shape as the bolt, it may cause the bolt and the matching hole 12111 to be staggered. The phenomenon. Therefore, setting the matching hole 12111 as a long hole can not only ensure that the bolt can be easily matched with the matching hole 12111, but also facilitate the construction personnel to adjust the position of the bolt, thereby facilitating the welding operation of the bolt and the lug plate 1211. It should be additionally explained here that the long hole here refers to that the shape of the matching hole 12111 is longer than the cross-sectional length of the bolt, and the specific shape of the long hole is not limited here. In the embodiment of the present invention, the long hole The shape of the bolt can be arbitrarily selected according to the shape of the bolt. Of course, in other embodiments of the present invention, a plurality of matching holes 12111 may be formed on the lug plate 1211 , so that the bolts and the matching holes 12111 can also be easily matched. In addition, since the bolts are welded on the lugs 1211, this connection method further ensures the connection between the support arm and the support arm tower section 121, improves the stability of the tower crane main body 220 during the construction process, and ensures construction safety. . Of course, the bolts may not be welded on the ear plate 1211, or the ear plate 1211 and the arm structure 230 may be connected by other means, such as riveting, hinged and other means.

In some embodiments, as shown in FIGS. 2 and 4 , the arm tower section 121 is further provided with an assembly assembly 130 , and the assembly assembly 130 includes an embedded part 131 , and the embedded part 131 is pre-embedded in the arm tower section 121 Inside, the ear plate 1211 is connected with the embedded part 131 . It can be understood that the lug plate 1211 is connected with an embedded part 131, and the embedded part 131 is pre-buried on the arm tower section 121, so the connection strength between the lug plate 1211 and the arm tower section 121 is good, The phenomenon that the lug plate 1211 falls off from the arm tower section 121 and causes the connection failure between the arm tower section 121 and the arm structure 230 is avoided.

In some embodiments, as shown in FIGS. 2 and 4 , the assembly assembly 130 includes an inner support 133 , the inner support 133 is provided on the inner peripheral wall of the arm tower section 121 , and one end of the embedded part 131 protrudes out of the support The boom tower section 121 is also connected with the inner support 133 . It should be noted that after the arm structure 230 is installed between the arm tower section 121 and the longitudinal truss 221 , the arm structure 230 will squeeze the arm tower section 121 . An inner support 133 is provided on the inner peripheral wall of the arm tower section 121, so that the inner support 133 exerts a force on the inner wall of the arm tower section 121, so as to prevent the arm structure 230 from affecting the arm tower section 121 The phenomenon of extrusion deformation occurs.

In some specific embodiments, as shown in FIG. 2 and FIG. 4 , the inner support 133 is a closed ring extending along the inner peripheral wall of the arm tower section 121 for a circle. In this way, the inner support of the inner support 133 on the arm tower section 121 can be ensured, and the deformation of the arm tower section 121 caused by the arm structure 230 pressing the arm tower section 121 is further avoided.

In some embodiments, as shown in FIGS. 2 and 4 , the assembly assembly 130 includes an outer support member 132 , the outer support member 132 is provided on the outer peripheral wall of the arm tower section 121 , and one end of the embedded member 131 protrudes from the support arm The arm tower section 121 is connected with the outer support 132 , and the ear plate 1211 is arranged on the outer support 132 . It can be understood that an outer support member 132 is provided on the outer peripheral wall of the arm tower section 121, and the outer support member 132 has a tightening effect on the arm tower section 121, thereby improving the strength of the arm tower section 121. The risk of deformation of the arm tower section 121 caused by the excessive force of the arm structure 230 on the arm tower section 121 is reduced. In addition, the provision of the lugs 1211 on the outer support member 132 can prevent the arm structure 230 from directly contacting the arm tower section 121, which further reduces the force of the arm structure 230 on the arm tower section 121 and causes the arm Risk of deformation of tower section 121.

In some specific embodiments, as shown in FIG. 2 and FIG. 4 , the outer support 132 is a closed ring extending along the outer peripheral wall of the arm tower section 121 for a circle. Therefore, the tightening effect of the outer support 132 on the arm tower section 121 can be ensured, and the deformation of the arm tower section 121 caused by the arm structure 230 pressing the arm tower section 121 is further avoided.

It should be noted here that, in the embodiment of the present invention, the inner support 133 and the outer support 132 may exist at the same time, or there may be only one, and when the inner support 133 and the outer support 132 exist at the same time, the inner support 133 and the outer support 132 exist at the same time. Both the support member 133 and the outer support member 132 may be formed as a closed loop extending along the peripheral wall of the arm tower section 121, only one of them may be formed as a closed loop, or neither may be a closed loop.

In some embodiments, as shown in FIG. 2 , the arm structure 230 includes four support bars 231 , and the four support bars 231 are arranged in an M-shape. It can be understood that, since the four support rods 231 are arranged in an M shape, among the four points of the intersection of the two support rods 231 and the longitudinal truss 221 and the intersection of the two support rods 231 and the support arm tower section 121, The distance between the intersection points of the two braces 231 and the longitudinal truss 221 is relatively close and can be approximately regarded as a point, so that the intersection of the two braces 231 and the longitudinal truss 221 and the two intersections of the two braces 231 and the arm tower section 121 A triangle is formed, which greatly improves the stability of the support bar 231, thereby ensuring the supporting effect of the concrete tower 10 on the tower crane main body 220, and better avoiding the phenomenon that the tower crane main body 220 rolls over.

In some embodiments, as shown in FIG. 3 , each support bar 231 includes a long straight tube 2311 , a first hinge portion 2312 and a second hinge portion 2313 , and the first hinge portion 2312 is provided at one end of the long straight tube 2311 . In order to be hingedly connected to the arm tower section 121 , the second hinge part 2313 is provided at the other end of the long straight pipe 2311 and is hingedly connected to the longitudinal truss 221 . The structures and dimensions of the first hinge parts 2312 of the four poles 231 are the same, and the structures and dimensions of the second hinge parts 2313 of the four poles 231 are the same. It can be understood that the first hinged part 2312 and the second hinged part 2313 of the four support rods 231 have the same structural dimensions, which ensures that the longitudinal truss 221 and the arm tower section 121 are respectively connected with the second hinged part 2313 and the second hinged part 2313. The connection structures connected by a hinge portion 2312 are the same, which facilitates mass production and reduces production costs. It should be noted here that, in the embodiment of the present invention, the connection between the first hinge portion 2312 and the second hinge portion 2313 and the long straight pipe 2311 may also be a fixed connection such as welding, riveting, etc., or a detachable connection such as a bolt connection. Connection.

In some specific embodiments, as shown in FIG. 3 , both ends of the long straight pipe 2311 are respectively provided with pipe flanges 23111 , the first hinge portion 2312 is provided with a first flange 23121 , and the second hinge portion 2313 is provided with a pipe flange 23111 . There is a second flange 23131, the first flange 23121 and the second flange 23131 are respectively connected to the two pipe flanges 23111 through a plurality of bolts, the pipe flange 23111, the first flange 23121 and the second flange 23131 There are multiple reinforcing ribs.

It can be understood that the first flange 23121 of the first hinge part 2312 and the pipe flange 23111 of the long straight pipe 2311 are connected by a plurality of bolts, and the second flange 23131 of the second hinge part 2313 and the long straight pipe 2311 are connected by a plurality of bolts. The pipe flanges 23111 are connected by multiple bolts. Therefore, the support bar 231 is formed as a split structure of the first hinge portion 2312 , the long straight tube 2311 and the second hinge portion 2313 , that is to say, when the length of the long straight tube 2311 changes, the entire support bar 231 The length can also vary accordingly. During the construction process, the construction personnel can replace the long straight pipe 2311 according to actual needs, so that the supporting rod 231 can meet the connection requirements. According to the foregoing description, the structures and dimensions of the first hinge portion 2312 and the second hinge portion 2313 of the four poles 231 are the same. Therefore, in the actual production process, only long straight pipes 2311 with different lengths and a sufficient number of first hinge parts 2312 and second hinge parts 2313 are needed, which reduces the types of parts actually used, and reduces procurement and transportation. cost. Of course, it should be noted here that the connection between the first flange 23121 and the second flange 23131 and the pipe flange 23111 is not limited to bolt connection, but can also be connected in various ways such as riveting and welding.

It should be added that the pipe flange 23111, the first flange 23121 and the second flange 23131 are provided with a plurality of reinforcing ribs, and the reinforcing ribs can ensure the pipe flange 23111, the first flange 23121 and the second flange. The strength of 23131 ensures the connection strength between the three, thereby ensuring the strength of the entire pole 231. It should be additionally explained that the reinforcing ribs here only play the role of increasing the strength of the parts, so the reinforcing ribs can be formed into any structure that can strengthen the strength of the parts, and no specific requirements are made for the specific shape and size of the reinforcing ribs.

In some optional embodiments, as shown in FIG. 3 , the first hinge portion 2312 includes a first hinge shaft 23122, a first connecting plate group 23123 and a first fixing member 23124, and the first connecting plate group 23123 covers the first On the hinge shaft 23122, the first connecting plate group 23123 is provided with a first connecting hole 231231 for being hinged on the arm tower section 121, and the center axis of the first connecting hole 231231 is perpendicular to the center line of the first hinge shaft 23122 , the first fixing member 23124 is sheathed on the first hinge shaft 23122, and the first fixing member 23124 is fixedly connected to the long straight pipe 2311. It can be understood that the first hinge portion 2312 is formed by splicing multiple parts, which facilitates the transportation and storage of the first hinge portion 2312, and the lengths of the first connecting plate group 23123 and the first fixing member 23124 can be adjusted according to actual needs. , so that the applicable range of the first hinge part 2312 is higher.
