Description

Net sheet for manufacturing square pile

Technical Field

The utility model relates to a building trade prefab field especially relates to a net piece for making square pile.

Background

With the continuous development of building pile foundation engineering, the prestressed square pile is more and more concerned by people. The prestressed square pile has the advantages of quick construction, reliable quality, capability of penetrating through various soil layers such as clay, silt, sandy soil and the like, no influence of underground water level and larger bearing capacity, thereby being widely applied to industrial and civil building engineering.

During the piling process, the energy obtained by the pile hammer is actually transmitted to the pile after various losses are removed, so that the pile overcomes the frictional resistance and pile tip resistance of the surrounding soil and sinks into the soil. The energy loss in the piling process mainly comprises impact resilience energy loss of a hammer, deformation energy loss of a pile and deformation energy loss of soil.

The main reasons for pile top crushing or pile body breakage in the pile construction process are various, and one of the most representative reasons is insufficient or improper allocation of the pile top reinforcing mesh.

The pile hammer hammering pile top produces very high hammering compressive stress, produces hammering tensile stress to the pile top again when the pile hammer rebounds simultaneously. If the configuration of the pile top reinforcing mesh is insufficient or not correct, the pile hammer can easily break or crack the concrete at the top of the pile.

Therefore, when the prestressed square pile is manufactured, in order to prevent the pile end from being broken during pile driving, one or more steel bar meshes are placed at the tensioning end of the reinforcement cage of the square pile in advance, so that the impact resistance and the strength of the pile head are effectively enhanced.

The 04G361 prefabricated reinforced concrete square pile (national standard) approved and issued by the Ministry of construction of the people's republic of China intensively specifies seven sizes of square piles, and the cross section sizes of the square piles are respectively as follows: 200 × 200, 250 × 250, 300 × 300, 350 × 350, 400 × 400, 450 × 450, 500 × 500 (units in mm). Several specifications are newly added in the process of adapting to production in construction, the sections of the prestressed square piles commonly used at present have seven sizes (unit is mm) of 300 multiplied by 300, 350 multiplied by 350, 400 multiplied by 400, 450 multiplied by 450, 500 multiplied by 500, 550 multiplied by 550 and 600 multiplied by 600, and correspondingly, the reinforcement cage of the square pile has corresponding specification standards.

At present, for square piles of different sizes and specifications, the used reinforcing mesh pieces also have corresponding specifications, namely, the square pile of one size and specification corresponds to the reinforcing mesh piece of one specification, and during installation, the reinforcing mesh piece and the stress bars of the reinforcement cage of the square pile are in frictional contact so as to fix the relative positions of the reinforcing mesh piece and the stress bars, namely, when the square pile of one size and specification is manufactured, only the reinforcing mesh pieces of the corresponding specifications can be adopted, so that the universality is poor, the cost is higher, and the manual operation is more complicated during the actual application.

In order to make the mesh structure in the present embodiment better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.

Currently, the size specifications of the universal square pile include seven size specifications of 300mm, 350mm, 400mm, 450mm, 500mm, 550mm and 600mm, and all the sizes are the side lengths of the finally manufactured square pile.

In practical application, square piles of 300mm and 350mm share one mesh, square piles of 400mm and 450mm share one mesh, square piles of 500mm and 550mm share one mesh, 600mm can still adopt the mesh which is matched at present, and thus the number of meshes in specifications can be reduced.

Referring to fig. 1 and 2, fig. 1 is a schematic structural view illustrating a first mesh sheet and a 300mm square pile according to an embodiment; FIG. 2 is a schematic view of a configuration of a first mesh sheet and a 350mm square pile according to an embodiment.

The first mesh provided by the embodiment can be matched with the 300mm square pile 21 and the 350mm square pile 31 at the same time, namely the first mesh shown in fig. 1 and 2 is of the same structure.

As shown in the figure, according to the relevant standards, three first stress ribs 221 are respectively corresponding to each cage side of a first rib cage corresponding to a 300 mm-sized square pile 21, so that the first rib cage has 8 first stress ribs 221 in total; every cage limit of the second muscle cage that 350mm specification square pile 31 corresponds all is equipped with three second atress muscle 321, and like this, the second muscle cage has 8 second atress muscle 321 altogether.

In this embodiment, the first mesh sheet includes four main ribs formed with a square structure, and for convenience of description, in the orientation shown in fig. 1 and 2, two main ribs arranged in the up-down direction are referred to as a first main rib 111a, and two main ribs arranged in the left-right direction are referred to as a second main rib 111b, and it is obvious that the first main rib 111a and the second main rib 111b are disposed perpendicular to each other; three first auxiliary ribs 112a which are parallel to each other and arranged at intervals are arranged between the two first main ribs 111a, and three second auxiliary ribs 112b which are parallel to each other and arranged at intervals are arranged between the two second main ribs 112 a.

As shown in fig. 1, after the first mesh sheet is installed on the first reinforcement cage of the 300mm square pile, one first main reinforcement bar 111a abuts against the outer sides of three first stress bars 221 of the first reinforcement cage, which are located on the edge of the upper cage, and it can be understood that the first main reinforcement bar 111a is arranged in a tangent manner with the three first stress bars 221; the other first main rib 111a is abutted against the outer sides of the three first stress ribs 221 of the first rib cage, which are located on the lower cage edge, so that the two first main ribs 111a clamp the first stress ribs 221 on the two opposite cage edges of the first rib cage, and the first main ribs 111a and the first stress ribs 221 are fixed through friction contact.

The outer side herein is, with respect to the square pile center, the side close to the square pile center as the inner side, and conversely, the side far from the square pile center as the outer side.

Through the arrangement of the auxiliary ribs, in this embodiment, two ends of the second auxiliary rib 112b located in the middle of the first mesh sheet are also respectively abutted to the two first stress ribs 221 corresponding to the positions, and two ends of the first auxiliary rib 112a located in the middle of the first mesh sheet are also respectively abutted to the two first stress ribs 221 corresponding to the positions.

The ribs of the first mesh sheet abutting the first force-bearing ribs 221 of the first rib cage are shown in bold solid lines. It can be seen that the structural arrangement of the first mesh sheet enables all the first stress ribs 221 of the first rib cage of the 300mm square pile 21 to be abutted against the ribs of the first mesh sheet, so that the reliability of relative fixation of the first stress ribs and the first mesh sheet can be improved.

As shown in fig. 2, after the first mesh sheet is installed with the second reinforcement cage of the 350mm square pile, one second main reinforcement 111b abuts against the inner sides of the three second stressed reinforcements 321 on the left cage edge of the second reinforcement cage, the other second main reinforcement 111b abuts against the inner sides of the three second stressed reinforcements 321 on the right cage edge of the second reinforcement cage, meanwhile, the two ends of the second auxiliary reinforcement 112b located in the middle portion abut against the second stressed reinforcements 321 located in the middle portion of the upper cage edge and the second stressed reinforcements 321 located in the middle portion of the lower cage edge respectively, and the two ends of the first auxiliary reinforcement 112a located in the middle portion abut against the second stressed reinforcements 321 located in the middle portion of the left cage edge and the second stressed reinforcements 321 located in the middle portion of the right cage edge respectively.

The ribs of the first web which abut the second stressing ribs 321 of the second rib cage are also indicated in the figure by thick solid lines. It can be seen that the structural arrangement of the first mesh sheet enables all the second stressed ribs 321 of the second rib cage of the 350mm square pile to be abutted against the ribs of the first mesh sheet, and the reliability of relative fixation of the two is high.

It can be seen from comparing fig. 1 and fig. 2, during the equipment, have some ribs in the first net piece neither with the first atress muscle 221 looks butt of first muscle cage, also with the second atress muscle 321 looks butt of second muscle cage, how much of the rib figure of first net piece is relevant with the net density degree of first net piece, the cooperation with the muscle cage should be taken into account to the rib figure of first net piece and the net density degree that forms to and ensure pile head intensity, that is to say, not all ribs are all for the atress muscle looks butt with the muscle cage.

The structural composition of the mesh sheet mainly aims to meet the following requirements: firstly, the net sheets can be placed on one side close to the end parts of the rib cage in a manner of being perpendicular to the stressed ribs after being inserted into the end parts of the rib cage without an external connecting means, and the density of the net sheets can ensure that concrete materials can be filled in the space between the end plate of the mould for manufacturing the square pile and the net sheets during material distribution; and secondly, the distribution of the ribs of the net piece can ensure that sufficient impact resistance is provided during piling, and the pile head is protected from being cracked.

Referring to fig. 3 and 4, fig. 3 is a schematic structural view illustrating a second mesh sheet and a 400mm square pile according to an embodiment; FIG. 4 is a schematic view of the second mesh sheet and a 450mm square pile according to an embodiment.

In this embodiment, the structural layout and the arrangement principle of the second mesh are the same as those of the foregoing scheme, except that: the second mesh is used for matching the 400mm square pile 41 and the 450mm square pile 51 at the same time, namely the second mesh shown in fig. 3 and 4 is the same structure.

As shown in the figure, according to the relevant standard, the third reinforcement cage corresponding to the 400mm square pile 41 is formed by 12 stress ribs in the cross section and is enclosed into a square shape, 4 stress ribs are distributed on one side, and the stress rib at the end part and 3 stress ribs on the same straight line form the other side; and each cage edge of the fourth reinforcement cage corresponding to the 450 mm-sized square pile 51 is provided with four fourth stress ribs 521, so that the total number of the fourth stress ribs 521 in the fourth reinforcement cage is 12.

In this embodiment, the second mesh includes four main ribs formed with a square structure, and specifically, two first main ribs 111a arranged in the up-down direction and two second main ribs 111b arranged in the left-right direction in the orientation shown in fig. 3 and 4.

In the second net piece, three first auxiliary ribs 112a which are parallel to each other and arranged at intervals are arranged between two first main ribs 111a, and three second auxiliary ribs 112b which are parallel to each other and arranged at intervals are arranged between two second main ribs 111 b.

The comparison shows that the number of the ribs of the first net piece is consistent with that of the ribs of the second net piece, but it can be understood that the overall size and the grid density degree of the first net piece are different from those of the second net piece because the size specifications of the square piles matched with the first net piece and the second net piece are different.

As shown in fig. 3, after the second mesh sheet is installed on the third rib cage of the 400mm square pile 41, one first main rib 111a abuts against the outer sides of four third stressed ribs 421 on the upper cage side of the third rib cage, the other first main rib 111a abuts against the outer sides of four third stressed ribs 421 on the lower cage side of the third rib cage, one second main rib 111b abuts against the outer sides of four third stressed ribs 421 on the left cage side of the third rib cage, and the other second main rib 111b abuts against the outer sides of four third stressed ribs 421 on the right cage side of the third rib cage, that is, the four main ribs of the second mesh sheet are externally hooped on the third stressed ribs 421 of the third rib cage.

The auxiliary ribs of the second mesh sheet are not in contact with the third stress ribs 421 of the third rib cage, and do not interfere with the third stress ribs 421.

The ribs of the second mesh sheet abutting the third stressing ribs 421 of the third rib cage are shown in the figure as thick solid lines. It can be seen that the second mesh sheet is configured such that all the third reinforcement bars 421 of the third reinforcement cage of the 400mm square pile 41 abut against the reinforcement bars of the second mesh sheet.

As shown in fig. 4, after the second mesh sheet is installed with the fourth rib cage of the 450 mm-sized square pile 41, each main rib is not in contact with the fourth stress rib 521 of the fourth rib cage, it can be understood that the cage side length of the fourth rib cage is greater than the cage side length of the third rib cage, the structural design of the second mesh sheet makes the four main ribs hoop outside the periphery of the third rib cage, and after the second mesh sheet is installed with the fourth rib cage, the four main ribs are inevitably located inside the cage sides of the fourth rib cage respectively. Therefore, in order to ensure that the second net piece can be reliably fixed with the fourth rib cage, the fixing requirements of the second net piece and the fourth rib cage are met through arrangement of the auxiliary ribs.

Specifically, in the orientation shown in fig. 4, from top to bottom, two ends of the first auxiliary rib 112a are respectively abutted against the second fourth stress rib 521 on the left cage side and the second fourth stress rib 521 on the right cage side, and two ends of the third first auxiliary rib 112a are respectively abutted against the third fourth stress rib 521 on the left cage side and the third fourth stress rib 521 on the right cage side.

From left to right, the two ends of the first second auxiliary rib 112b are respectively abutted to the second fourth stress rib 521 on the upper cage edge and the second fourth stress rib 521 on the lower cage edge, and the two ends of the third second auxiliary rib 112b are respectively abutted to the third fourth stress rib 521 on the upper cage edge and the third fourth stress rib 521 on the lower cage edge.

In the graph, ribs abutted to the fourth stress rib 521 of the fourth rib cage in the second mesh sheet are also shown in a thick solid line form, and it can be seen that the structural arrangement of the second mesh sheet enables 8 fourth stress ribs 521 in the fourth rib cage of the square pile 51 with the specification of 450mm to be abutted to the ribs of the second mesh sheet, the number of the fourth stress ribs 521 exceeds half of the total number 12 of the fourth stress ribs 521, and the second mesh sheet and the fourth rib cage can be reliably fixed.

Referring to fig. 5 and 6, fig. 5 is a schematic structural view illustrating a third mesh sheet and a 500mm square pile according to an embodiment of the present invention; FIG. 6 is a schematic view of a third mesh sheet engaged with a 550mm square pile according to an embodiment of the present invention.

In this embodiment, the structural layout and the arrangement principle of the third mesh have the same difference with the above-mentioned scheme: the third mesh is used for matching the 500m square pile 61 and the 550mm square pile 71 at the same time, namely the third mesh shown in fig. 5 and 6 is of the same structure.

As shown in the figure, according to the relevant standards, 5 fifth stress bars 621 are arranged on each cage side of the fifth reinforcement cage corresponding to the 500 mm-sized square pile 61, so that the number of the fifth reinforcement cage is 16; each cage edge of the sixth reinforcement cage corresponding to the 550 mm-sized square pile 71 is provided with 5 sixth stress ribs 721, so that the sixth reinforcement cage has 16 sixth stress ribs 721.

In this embodiment, the third mesh includes four main ribs formed with a square structure, and specifically, two first main ribs 111a arranged in the up-down direction and two second main ribs 111b arranged in the left-right direction in the orientation shown in fig. 5 and 6.

In the third net piece, four first auxiliary ribs 112a which are parallel to each other and arranged at intervals are arranged between two first main ribs 111a, and four second auxiliary ribs 112b which are parallel to each other and arranged at intervals are arranged between two second main ribs 111 b.

As shown in fig. 5, after the third mesh sheet is installed on the fifth reinforcement cage of the 500 mm-sized square pile 61, one first main rib 111a abuts against the outer sides of the five fifth stress ribs 621 on the upper cage side of the fifth reinforcement cage, the other first main rib 111a abuts against the outer sides of the five fifth stress ribs 621 on the lower cage side of the fifth reinforcement cage, one second main rib 111b abuts against the outer sides of the five fifth stress ribs 621 on the left cage side of the fifth reinforcement cage, the other second main rib 111b abuts against the outer sides of the five fifth stress ribs 621 on the right cage side of the fifth reinforcement cage, that is, the four main ribs of the third mesh sheet are externally hooped on the fifth stress ribs 621 of the fifth reinforcement cage.

On the basis, the third net sheet also has four auxiliary ribs which are abutted with the fifth stress rib 621 of the fifth rib cage at the corresponding position. Specifically, in the orientation shown in fig. 5, from top to bottom, two ends of a first secondary rib 112a are respectively abutted to a second fifth stress rib 621 on the left cage side and a second fifth stress rib 621 on the right cage side, and two ends of a fourth first secondary rib 112a are respectively abutted to a fourth fifth stress rib 621 on the left cage side and a fourth fifth stress rib 621 on the right cage side; from left to right, the two ends of the first second auxiliary rib 112b are respectively connected with the second fifth stress rib 621 on the upper cage edge and the second fifth stress rib 621 on the lower cage edge in an abutting manner, and the two ends of the fourth second auxiliary rib 112b are respectively connected with the fourth fifth stress rib 621 on the upper cage edge and the fourth fifth stress rib 621 on the lower cage edge in an abutting manner.

In the figure, the ribs of the third mesh sheet abutting against the fifth stress bars 621 of the fifth rib cage are also shown in a thick solid line form, and it can be seen that the structure of the third mesh sheet is arranged so that all the fifth stress bars 621 of the fifth rib cage of the 500mm square pile 61 abut against the ribs of the third mesh sheet.

As shown in fig. 6, after the three-mesh-sheet is installed with the sixth reinforcement cage of the 550 mm-sized square pile 71, each main reinforcement bar is not in contact with the sixth stress bar 721 of the sixth reinforcement cage, it can be understood that the cage side length of the sixth reinforcement cage is greater than the cage side length of the fifth reinforcement cage, the structural design of the third mesh-sheet makes four main reinforcement bars hoop outside the periphery of the fifth reinforcement cage, and the four main reinforcement bars are inevitably located inside the four cage sides of the sixth reinforcement cage respectively after the third mesh-sheet is installed with the sixth reinforcement cage. Therefore, the requirement that the auxiliary ribs of the third net piece are reliably fixed with the sixth rib cage through friction contact is met through arrangement of the auxiliary ribs of the third net piece.

Specifically, in the orientation shown in fig. 6, from top to bottom, two ends of the first auxiliary rib 112a are respectively abutted against the second sixth stress rib 721 on the left cage side and the second sixth stress rib 721 on the right cage side, and two ends of the fourth first auxiliary rib 112a are respectively abutted against the fourth sixth stress rib 721 on the left cage side and the fourth sixth stress rib 721 on the right cage side; from left to right, two ends of the first second secondary rib 112b are respectively abutted to the second sixth stress rib 721 on the upper cage edge and the second sixth stress rib 721 on the lower cage edge, and two ends of the fourth second secondary rib 112b are respectively abutted to the fourth sixth stress rib 721 on the upper cage edge and the fourth sixth stress rib 721 on the lower cage edge.

In the figure, the ribs of the third mesh and the sixth stress bar 721 of the sixth rib cage are also shown in a thick solid line form, and it can be seen that the structural arrangement of the third mesh enables 8 sixth stress bars 721 in the sixth rib cage of the 550mm square pile 71 to abut against the ribs of the third mesh, the number of the sixth stress bars 721 is half of the total number 16 of the sixth stress bars 721, and the third mesh and the sixth rib cage can be reliably fixed.

As can be seen from comparison between fig. 5 and fig. 6, each auxiliary rib abutted to the fifth stress bar 621 of the third mesh sheet is consistent with each auxiliary rib abutted to the sixth stress bar 721 of the third mesh sheet, and in view of the different sizes of the fifth rib cage and the sixth rib cage, the specific position abutted to the fifth stress bar 621 of the same auxiliary rib is different from the specific position abutted to the sixth stress bar 721 of the same auxiliary rib. In the orientation shown in fig. 5 and 6, from top to bottom, when the first auxiliary rib 112a is engaged with the fifth rib cage, the first auxiliary rib 112a is specifically abutted against the upper side of the second fifth stress rib 621 on the left and right cage edges, and when the first auxiliary rib 112a is engaged with the sixth rib cage, the first auxiliary rib 112a is specifically abutted against the lower side of the second sixth stress rib 721 on the left and right cage edges.

Three dimensional mesh forms are described above with mesh cells having a square configuration.

When the net sheet with the structure is specifically arranged, the lengths of all ribs of the net sheet can be basically the same, so that the net sheet which is approximately square is formed, and the manufacture of the net sheet is facilitated.

In addition, according to the preparation demand of square pile, after the square pile was made, the rib of net piece should not stretch out each surface of square pile, and the net piece still should reliably cooperate with the muscle cage of square pile simultaneously, so, when the net piece in this scheme cooperates with the muscle cage of the square pile of two adjacent size specifications, the size compromise both.

Specifically, in the scheme, for the mesh sheets matched with two square piles of adjacent size specifications, the length of the ribs of the mesh sheets is smaller than the side length of a first square pile of a relatively smaller size specification and is larger than the side length of a square formed by connecting central points of a second rib cage of a second square pile of a relatively larger size specification. In fig. 1 to 6, a square formed by connecting the center points of the corresponding reinforcement cage is shown in a dotted line.

It should be further noted that, in the above-described meshes with three sizes, the number of the first auxiliary ribs 112a of each mesh is the same as that of the second auxiliary ribs 112b, it can be understood that, in actual setting, the number of the first auxiliary ribs and the second auxiliary ribs may also be different, and the number and arrangement thereof only need to satisfy the fixing requirement of the matched reinforcement cage and ensure the pile head strength.

Besides the net sheet of the scheme, the utility model provides a net sheet has other structural style.

In another specific scheme, a plurality of ribs of the mesh are divided into a first rib group and a second rib group, wherein the ribs of the first rib group are arranged in parallel along a first direction, and the ribs of the second rib group are arranged in parallel along a second direction.

The first direction is crossing with the second direction, and first direction and second direction all set up with the stake limit place direction looks slope of square pile, that is to say, in this scheme, the rib of net piece inclines mutually with the stake limit of square pile, also the cage limit of the muscle cage of square pile sets up with the slope mutually.

In order to avoid that the ribs of the mesh sheet extend out of the surfaces of the square pile after the square pile is manufactured, it is obvious that the lengths of the ribs of the mesh sheet are not exactly the same in this solution.

It can be understood that when the arrangement of each rib in the first rib group and the arrangement of each rib in the second rib group in the net piece should satisfy the cooperation of the net piece and the rib cage of two adjacent square piles of size specification, all there are more than half of stress bars butt of partial rib and rib cage, obviously, the position of other ribs that do not butt with stress bars should not interfere with stress bars either.

On this basis, the accessible sets up the muscle cage cooperation that makes net piece and two adjacent square piles of specification of a dimension through arranging of muscle strip, with the muscle strip of the atress muscle butt of muscle cage, have two alternately at least, like this, can improve muscle cage and net piece relatively fixed's reliability.

The scheme will be described below by taking a mesh sheet which is matched with the 400mm square pile 41 and the 450mm square pile 51 at the same time as an example.

Referring to fig. 7 and 8, fig. 7 is a schematic structural view illustrating a fourth mesh sheet and a 400mm square pile according to an embodiment of the present invention; FIG. 8 is a schematic structural diagram of a fourth mesh sheet engaged with a square pile of 450mm gauge in an embodiment.

In the illustrated embodiment, the first rib group of the fourth mesh has 5 first ribs 121a, and the second rib group has 5 second ribs 121 b.

In this embodiment, as shown in fig. 7 and 8, in the fourth mesh, 5 first ribs 121a are arranged in parallel along a first direction, specifically, the first direction is approximately one diagonal direction of the 400mm square pile 41, and 5 second ribs 121b are arranged in parallel along a second direction, specifically, the second direction is approximately the other diagonal direction of the 400mm square pile 41.

As shown in fig. 7, after the fourth mesh is installed on the third reinforcement cage of the 400 mm-sized square pile 41, 5 first ribs 121a of the first rib group are all abutted to third stress ribs 421 of the third reinforcement cage, specifically, both ends of each first rib 121a are abutted to the third stress ribs 421, it can be understood that, with respect to each cage edge of the third reinforcement cage, the first ribs 121a are obliquely arranged, so that two third stress ribs 421 abutted to the first ribs 121a are respectively located on two adjacent cage edges, which can be understood with reference to fig. 7 specifically; 3 second ribs 121b located in the middle of the second rib group are all abutted to the third stress rib 421 of the third rib cage, and similarly, two third stress ribs 421 abutted to two ends of the second rib 121b are also located on two adjacent cage edges respectively.

In the drawing, the ribs of the fourth mesh sheet abutting against the third reinforcing bars 421 of the third rib cage are shown in a thick solid line form, and it can be seen that the structure of the fourth mesh sheet is arranged so that all the third reinforcing bars 421 of the third rib cage of the 400mm square pile 41 abut against the ribs of the fourth mesh sheet.

As shown in fig. 8, after the fourth mesh sheet and the fourth reinforcement cage of the 450 mm-sized square pile 51 are installed, both ends of 4 first ribs 121a in the first rib group are abutted with fourth stress ribs 521, and in the direction from the upper left corner to the lower right corner of the 450 mm-sized square pile 51, both ends of the first, second, fourth and fifth first ribs 121a are abutted with fourth stress ribs 521 in the direction shown in fig. 8; the two ends of 1 second rib 121b in the second rib group are abutted with fourth stress ribs 521, which are the second ribs 121b near the left lower corner of the 450mm square pile 51 in the figure.

In the graph, ribs abutted to the fourth stress rib 521 of the fourth rib cage in the fourth mesh are also shown in a thick solid line form, and it can be seen that the structural arrangement of the fourth mesh enables 8 fourth stress ribs 521 in the fourth rib cage of the square pile 51 with the specification of 450mm to be abutted to the ribs of the fourth mesh, the number of the fourth stress ribs 521 exceeds half of the total number 12 of the fourth stress ribs 521, and the reliability that the fourth mesh and the fourth rib cage are fixed relatively can be guaranteed.

In the illustrated embodiment, the number of the ribs of the first rib group is the same as the number of the ribs of the second rib group, and it can be understood that the ribs may be arranged differently in practice.

In addition, during actual setting, the angle between the first rib 121a and the edge of the cage and the angle between the first rib 121a and the second rib 121b can be set as required.

According to the manufacturing requirement of the square pile, after the square pile is manufactured, ribs of the net piece do not extend out of the surfaces of the square pile, and meanwhile, the net piece is also reliably matched with a rib cage of the square pile, so that the whole size of the net piece in the scheme needs to be compatible with the rib cage of the square pile with two adjacent sizes matched with the net piece.

Specifically, in the scheme, for the mesh sheets matched with the two square piles of adjacent sizes, along the direction of the pile edge of the square pile, the size of the mesh sheets is smaller than the side length of the first square pile of the small size and larger than the side length of the square formed by connecting the central points of the second reinforcement cages of the second square pile of the large size. In fig. 7 and 8, the squares formed by connecting the respective center points of the corresponding cage are shown in dashed lines.

In practical application, each rib of the net sheet is a reinforcing bar, and the reinforcing bars can be fixed through welding.
