The following describes a corrugated pipe positioning assembly 3 for tower casting according to an embodiment of the present invention with reference to the drawings.

A corrugated pipe positioning assembly 3 for tower casing according to an embodiment of the present invention, as shown in fig. 1 and 2, includes: a fixed plate 31 and a positioning rod 33.

The fixing plate 31 is suitable for being arranged at the top of the pouring cavity 5 of the prefabricated tower barrel, and the fixing plate 31 is provided with a corrugated pipe fixing hole 32. The bellows fixing hole 32 is mainly used to mount and position the bellows 6.

As shown in fig. 1, the number of the fixing plates 31 is plural, the plurality of fixing plates 31 are radially arranged, and one ends of the plurality of fixing plates 31 facing each other are connected. That is, the ends of the fixing plates 31 are connected to the ends close to each other, and here, the ends of the fixing plates 31 may be directly connected to each other, for example, integrally formed; alternatively, the ends of the plurality of fixed plates 31 may be indirectly connected by other structures, such as a common fixed structure to the structural member of the radiation center. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

As shown in fig. 1 and 2, the positioning rod 33 is partially inserted into the bellows fixing hole 32 and partially extends below the fixing plate 31, the positioning rod 33 is detachably connected to the fixing plate 31, and the positioning rod 33 is used to cover the bellows 6. The positioning rod 33 may be detachably connected to the fixing plate 31 in the form of: the top of the positioning rod 33 is provided with a threaded hole which is matched and connected by a screw; the positioning rod 33 and the fixing plate 31 can be fixed in a clamping and inserting mode and the like; an interference fit is also possible and is not specifically limited herein.

As can be seen from the above structure, in the corrugated pipe positioning assembly 3 for casting a tower drum according to the embodiment of the present invention, by arranging the plurality of radial fixing plates 31 with one end connected to each other, one end of each fixing plate 31 is fixed with respect to the casting cavity 5, while the other end forms a free end and is respectively arranged at the top of the casting cavity 5, the plurality of fixing plates 31 can be simultaneously arranged at a plurality of positions of the same casting cavity 5, so that a plurality of corrugated pipes 6 can be simultaneously arranged in one casting cavity 5, and the supporting efficiency of the corrugated pipes 6 is high. In addition, since one end of the fixing plate 31 is connected, the connection ends of the fixing plates 31 are stable and are not easy to move.

The positioning rod 33 can be penetrated into the corrugated pipe fixing hole 32 on the fixing plate 31 to further be sleeved into the corrugated pipe 6 (the structure of the corrugated pipe 6 is shown in fig. 4), a relatively fixed position is provided for arranging the corrugated pipe 6 in the pouring cavity 5, the corrugated pipe 6 is positioned quickly, and the arrangement of the corrugated pipe 6 does not need to depend on a side template too much.

After the positioning rod 33 is detachably connected in the fixing plate 31, on one hand, the positioning rod 33 provides longitudinal support for the fixing plate 31, so that the fixing plate 31 is stably arranged at the top of the pouring cavity 5; on the other hand, after the corrugated tube 6 is fitted to the positioning rod 33 provided in the corrugated tube fixing hole 32, the corrugated tube 6 provided in the casting cavity 5 can be stabilized, and the arrangement path of the corrugated tube 6 can be guided. The inside of the corrugated pipe 6 is supported by the positioning rod 33, so that the corrugated pipe 6 has enough deformation resistance, and the influence of the extrusion deformation of the inner side template and the outer side template on the corrugated pipe 6 is small.

It can be understood that compared with the structure that the corrugated pipe is attached and connected to the side die in the prior art, the corrugated pipe 6 provided by the invention is not dependent on the side die too much, and a connecting hole does not need to be formed in the side die. In addition, the corrugated pipe 6 of the present invention can realize rapid positioning through the corrugated pipe fixing hole 32 on the fixing plate 31, and the corrugated pipe 6 is sleeved on the positioning rod 33, which can significantly increase the deformation resistance of the corrugated pipe 6 and effectively avoid the translocation of the corrugated pipe 6.

In some embodiments of the present invention, as shown in fig. 1, 2 and 3, bellows positioning assembly 3 further comprises a post 34. The casting cavity 5 surrounds the outer side of the upright column 34, the fixing plates 31 are arranged in a radial mode relative to the upright column 34, and one ends, facing each other, of the fixing plates 31 are connected with the upright column 34. Thus, the columns 34 connect the ends of all the fixed plates 31, so that the ends of the fixed plates 31 are supported by the columns 34, without pressing the entire weight against the casting cavity 5 and as a sidewall mold. When in the process of pouring, each fixing plate 31 is less affected by the extrusion deformation of the inner and outer mold assemblies 2.

Alternatively, as shown in fig. 3, the casting cavity 5 is formed in an annular shape and has a reference central axis OO ', the central axis of the upright column 34 coincides with the reference central axis OO', and the plurality of fixing plates 31 are uniformly arranged around the upright column 34 at intervals in the circumferential direction, that is, the included angles between two adjacent fixing plates 31 are equal. The respective fixing plates 31 on the annular casting cavity 5 are uniformly arranged in the circumferential direction, so that the corrugated pipes 6 connected to the fixing plates 31 are uniformly arranged in the casting cavity 5. When the wind power generation tower barrel is built at the later stage, the corrugated pipe 6 is additionally provided with the prestressed ribs, so that the stability of the whole concrete tower barrel is facilitated, and the strength of the whole concrete tower barrel is high enough.

Of course, in other examples, the fixing plates 31 of the present invention may also be non-uniformly arranged in the circumferential direction of the column 34, that is, the included angles between the adjacent fixing plates 31 may not be equal, and if the positions of a plurality of corrugated tubes 6 need to be supported, the included angles between the adjacent fixing plates 31 are smaller; and the included angle between the adjacent fixing plates 31 is larger at the position where fewer corrugated pipes 6 need to be supported. And is not particularly limited herein.

Alternatively, as shown in fig. 1, 2 and 3, each of the fixing plates 31 is provided with a plurality of bellows fixing holes 32 in a circumferential direction. The plurality of corrugated pipe fixing holes 32 arranged along the circumferential direction are located in the same pouring cavity 5, a plurality of corrugated pipes 6 are conveniently distributed in the pouring cavity 5 in a concentrated mode at multiple positions, and therefore the prestressed ribs in each construction stage are conveniently added when a wind power generation tower barrel is built in the later period.

Alternatively, as shown in fig. 1, 2 and 3, a plurality of sets of bellows fixing holes 32 are provided at intervals along the length direction on each fixing plate 31. Therefore, the same group of corrugated pipe positioning assemblies 3 can adapt to pouring of concrete tower barrels or concrete tower pieces with different sizes without replacing the corrugated pipe positioning assemblies 3. In addition, in some examples, when a plurality of casting cavities 5 are arranged under the fixing plate 31 at intervals, the corrugated pipes 6 can be arranged for the plurality of casting cavities 5 at the same time, so that the plurality of casting cavities 5 can be conveniently erected with the required corrugated pipes 6 at the same time when casting. The arrangement space is saved, the input amount of the corrugated pipe positioning assembly 3 is saved, and the prefabricating efficiency of the concrete tower barrel or the concrete tower piece is improved.

In some embodiments of the present invention, as shown in fig. 2, 3 and 6, each fixing plate 31 includes: two slide rails 311 and a sled 312. Wherein the sliding plate 312 is adjustably fitted between the two sliding rails 311, and the bellows fixing hole 32 is provided on the sliding plate 312. That is, the sliding plate 312 in this structure can be adjusted in position on the sliding rail 311 to be away from or close to the connection end of the fixed plate 31. It will be appreciated that the slide 312 may be adjusted to a particular resting position on the slide 311 to accommodate the placement of concrete towers or concrete tower segments of various sizes and types, as long as the slide 311 is of a suitable length.

Since the fixing plate 31 is composed of the slide rails 311 and the slide plates 312, the slide plates 312 do not need to be longer to adapt to casting of concrete towers or concrete tower pieces with various sizes, and on the contrary, the length of a single slide plate 312 only needs to be greater than the wall thickness of the casting cavity 5, so that the requirement of arranging the corrugated pipe 6 in the casting cavity 5 can be met. Therefore, compared with the fixed plate 31 which is longer and can not move, the sliding plate 312 with the proper length and the sliding rail 311 with the enough length are adopted in the invention, the overall weight is lighter, the movement of the sliding plate 312 is more flexible, and the position of the sliding plate 312 on the sliding rail 311 can be quickly adjusted when pouring is carried out, so that the sliding plate 312 is opposite to the pouring cavity 5 and the corrugated pipe 6 is supported.

In addition, the sliding plate 312 does not need to be provided with too many corrugated pipe fixing holes 32, and the positions of the sliding plate 312 on the sliding rail 311 are moved, so that the corrugated pipe fixing holes 32 are stopped at the tops of the pouring cavities 5 at different positions, and the adjustment is flexible and the adaptability is strong.

Alternatively, as shown in fig. 6 and 8, one sides of the two slide rails 311 facing each other form a slide groove 3111, and opposite sides of the slide plate 312 are fitted in the slide groove 3111. The slide rails 311 not only provide a guiding function for the slide rails 312, but also provide a support for the slide plates 312.

In some examples, the sliding plate 312 is positioned in cooperation with the sliding rail 311, for example, a plurality of stoppers are disposed on the sliding rail 311, and when the sliding plate 312 slides to a specific position, the stoppers stop on the sliding plate 312 or stop at the side of the sliding plate 312. For example, the slide rail 311 and the slide plate 312 are provided with through holes, and when the slide rail slides to a specific position, the through holes of the slide rail and the slide plate are corresponding to each other, and the positioning member is inserted into the through holes to form a stop.

In some examples, the slide rails 311 are positioned in cooperation with a sidewall mold of the casting cavity 5.

Specifically, as shown in fig. 4, the fixing plate 31 is provided with a positioning hole 313 and a positioning pin 4 inserted in the positioning hole 313, and the positioning pin 4 is adapted to be fitted on a sidewall mold of the casting cavity 5. When fixed plate 31 is fixed a position on the lateral wall mould of pouring chamber 5, multiplicable lateral wall mould's top joint strength forms better support to the top of lateral wall mould, effectively prevents to pour the deformation at in-process lateral wall mould top, also can prevent effectively that lateral wall mould from extrudeing when warping and causing the influence to bellows 6.

Alternatively, the bellows fixing hole 32 of each slide plate 31 is provided in plural in the circumferential direction. So that a plurality of bellows 6 are arranged in the same position in the casting cavity 5.

Of course, in other examples, as shown in fig. 1 and 5, the fixing plate 31 is integrally formed as a plate-shaped body with a constant length, one end of the plate-shaped body is connected to the upright post 34, and a plurality of sets of corrugated pipe fixing holes 32 are formed in the plate-shaped body along the length direction, so as to be convenient for adapting to pouring cavities 5 with various sizes and simultaneously connecting the plate-shaped body to a plurality of pouring cavities 5. In addition, when a plurality of pouring cavities 5 are arranged at the periphery of the upright post 34 at intervals, the plate-shaped body can be fixed at the tops of the pouring cavities 5, the top connection of each pair of inner formworks 21a and outer formworks 21b is increased, side formworks at two sides of the pouring cavities 5 can be further supported, the strength of the top of the pouring mold 100 is increased, and the extrusion deformation of the pouring mold 100 caused by pressure generated during pouring is further reduced.

The casting mold 100 for a prefabricated tower according to an embodiment of the present invention is described below with reference to the accompanying drawings, and includes: bottom die 1, interior outer mould subassembly 2 and bellows locating component 3.

As shown in fig. 1, 2 and 3, the inner and outer mold assemblies 2 include at least one pair of inner mold plates 21a and outer mold plates 21b arranged at intervals, a casting cavity 5 is formed between each pair of inner mold plates 21a and outer mold plates 21b and the bottom mold 1, the inner side wall of each casting cavity 5 is constructed by the inner mold plates 21a, the outer side wall of each casting cavity 5 is constructed by the outer mold plates 21b, and the bottom wall of each casting cavity 5 is constructed by the bottom mold 1. When the inner and outer mold assemblies 2 form a pair of spaced apart inner and outer mold plates 21a, 21b, a casting cavity 5 is formed between the pair of inner and outer mold plates 21a, 21 b. When the inner and outer die assemblies 2 are formed as a plurality of pairs of inner and outer die plates 21a and 21b, a plurality of casting cavities 5 formed between the pairs of inner and outer die plates 21a and 21b are sequentially spaced apart in the radial direction. For example, in some examples, two pairs of inner and outer forms 21a, 21b are spaced apart in sequence around the column 34 to form two radially spaced apart casting cavities 5.

As shown in fig. 4, when the plurality of pairs of inner formworks 21a and outer formworks 21b form a plurality of casting cavities 5 arranged at intervals in the radial direction, the inner formwork 21a between two adjacent casting cavities 5 is a side wall (inner side wall) of the casting cavity 5 far away from the reference central axis OO ', and the outer formwork 21b between two adjacent casting cavities 5 is a side wall (outer side wall) of the casting cavity 5 near the reference central axis OO'.

Advantageously, as shown in fig. 4, the inner formwork 21a and the outer formwork 21b between two adjacent casting cavities 5 are connected by additionally arranging a fixing member, the inner formwork 21a and the outer formwork 21b are respectively provided with overlapping edges, and the overlapping edges are connected by the fixing member after being overlapped. The inner formwork 21a and the outer formwork 21b between two adjacent pouring cavities 5 are more stable and are not easy to deflect after being stressed.

Specifically, the longitudinal sections of the inner formwork 21a and the outer formwork 21b are formed into half-enclosed portal formwork frames, and the two portal formwork frames are oppositely arranged to form partition walls of adjacent casting cavities 5 with frame-shaped longitudinal sections. The inner formwork 21a and the outer formwork 21b between two adjacent pouring cavities 5 are conveniently supported, the processing is convenient, and the arrangement and the formation of a plurality of pouring cavities 5 arranged at intervals along the radial direction are facilitated.

In some examples, the casting cavity 5 is annular to cast a concrete tower. In other examples, the casting cavity 5 is curved to cast the concrete tower.

The corrugated pipe positioning assembly 3 is the corrugated pipe positioning assembly 3 for pouring the tower drum, and the structure of the corrugated pipe positioning assembly 3 is not described herein in detail.

As shown in fig. 1, 2 and 3, a plurality of fixing plates 31 are provided on the inner and outer mold assemblies 2, and positioning rods 33 extend into the casting cavity 5.

According to the structure, when the corrugated pipe 6 is arranged in the casting cavity 5 for casting the annular concrete tower tube or the concrete tower piece, the fixing plate 31 is arranged on the inner and outer die assemblies 2, the positioning rod 33 extends into the casting cavity 5, the top of the positioning rod 33 or/and the top of the inner and outer die assemblies 2 form a certain support for the fixing plate 31, and the fixing plate 31 is fixed on the top of the inner and outer die assemblies 2, so that the top connection strength of the inner and outer die assemblies 2 is enhanced, and the casting mold 100 for the prefabricated tower tube has a good deformation prevention effect. After the corrugated pipe 6 is sleeved on the positioning rod 33, the corrugated pipe 6 in the pouring cavity 5 is not easy to deform and translocation after being subjected to extrusion force because the inner mold assembly 2 and the outer mold assembly 2 are not easy to deform.

As shown in fig. 1 and 2, when a pair of inner and outer formworks 21a and 21b are provided, only one casting cavity 5 is formed, and the molds of the two side walls of the casting cavity 5 are respectively referred to as an inner formwork 211 and an outer formwork 212, wherein the mold of the side wall located at the inner side (e.g., a position close to the upright post 34) is referred to as the inner formwork 211, and the mold of the side wall located at the outer side (e.g., a position far from the upright post 34) is referred to as the outer formwork 212. The distance between the inner 211 and outer 212 formworks determines the thickness of the casting cavity 5. The inner and outer formworks 211 and 212 may be selected to have a suitable thickness to increase their resistance to deformation.

Optionally, a plurality of support ribs 22 (see fig. 2 for structures of the support ribs 22) are respectively disposed on the surfaces of the inner formwork 211 located at the innermost layer and the outer formwork 212 located at the outermost layer along the circumferential direction, so as to enhance the structural strength of the inner formwork 211 and the outer formwork 212 themselves, and easily cooperate with an external support structure, so that the whole casting mold 100 is effectively supported, and a large deformation is prevented from occurring in the casting process.

In some embodiments of the present invention, as shown in fig. 3, the inner and outer mold assemblies 2 include at least two pairs of inner and outer mold plates 21a and 21b, the at least two pairs of inner and outer mold plates 21a and 21b are sequentially spaced apart from the plurality of casting cavities 5 formed in the bottom mold 1 in a radial direction, the outer mold plate 21b between two adjacent casting cavities 5 forms an outer sidewall of the casting cavity 5 at a radially inner side, and the inner mold plate 21a between two adjacent casting cavities 5 forms an inner sidewall of the casting cavity 5 at a radially outer side. When the inner and outer die assemblies 2 are adopted, at least two groups of the inner and outer die assemblies can be poured simultaneously when a concrete tower barrel or a concrete tower piece is poured, pouring is rapid, and the required occupied construction space is saved. It can be understood that by adjusting the distance between the inner formwork 21a and the outer formwork 21b between two adjacent casting cavities 5, the distance between two casting cavities 5 can be adjusted, and further, the radial dimension of the separated concrete tower barrels formed by casting 5 can be adjusted, or the radial dimension of the separated concrete tower pieces after being enclosed into the tower barrel can be adjusted.

In some embodiments of the present invention, as shown in fig. 2 and 3, the fixing plate 31 is engaged with the inner and outer mold assemblies 2 by the positioning pins 4. Therefore, the fixing plate 31 is fixed with the inner and outer die assemblies 2, so that the inner and outer die assemblies 2 can be well supported, the inner and outer die assemblies 2 are effectively prevented from deforming in the pouring process, and the influence of extrusion force formed by the inner and outer die assemblies 2 in the pouring process on the corrugated pipe 6 is further reduced.

In some embodiments of the present invention, as shown in fig. 7, the bottom mold 1 is provided with a jacking hole 11 corresponding to the casting cavity 5, and a jacking mechanism is arranged below the casting cavity 5 and has a jacking rod capable of extending to the casting cavity 5 through the jacking hole 11. So, after having pour the concrete in pouring cavity 5, at the in-process of drawing of patterns behind concrete tower section of thick bamboo or the shaping of concrete tower piece, the jacking pole stretches into in pouring cavity 5 from jacking hole 11 to carry out the jacking to the bottom of concrete tower section of thick bamboo or concrete tower piece, thereby make the quick drawing of patterns of prefabricated concrete tower section of thick bamboo or concrete tower piece, and need not to use hoisting equipment.

Advantageously, as shown in fig. 7, the jacking holes 11 are spaced along the radial direction of the bottom die 1, and a plurality of jacking holes 11 are provided in the circumferential direction of the bottom die 1 at equal distances from the reference central axis OO'. When the drawing of patterns, the jacking rod evenly jacks a concrete tower section of thick bamboo or concrete tower piece in pouring cavity 5, and is difficult for inclining when making the drawing of patterns of a prefabricated concrete tower section of thick bamboo or concrete tower piece, promotes the security.

Optionally, the bottom mold 1 has a double-layer structure. The upper layer of the bottom die 1 is connected with the inner die assembly and the outer die assembly 2 to limit a pouring cavity 5, and the jacking mechanism is connected to the lower layer of the bottom die 1. From this, when climbing mechanism when the jacking concreted tower section of thick bamboo or the concrete tower piece in the cavity 5, climbing mechanism's bottom received the reaction force of jacking and the gravity of concreted tower section of thick bamboo or concrete tower piece for die block 1 keeps in the bottom, makes things convenient for die block 1 and whole prefabricated concreted tower section of thick bamboo or concrete tower piece to break away from, makes die block 1 easily take off, and can not adhere to the bottom at concreted tower section of thick bamboo or concrete tower piece.
