A first filling chamber 130 is arranged in the insertion section 110. A first opening 131 is provided at an end of the insertion section 110 remote from the support section 120, the first opening 131 being in communication with the first filling cavity 130. A connecting channel 140 is provided at the side of the insertion section 110, the connecting channel 140 communicating with the first filling chamber 130. In a state where the insertion section 110 is inserted into the hole of the pile body 170, the filler in the hole of the pile body 170 can be filled in the first filling cavity 130 through the connection passage 140 and the first opening 131; in a state where the first filling cavity 130, the connecting channel 140 and the filling material in the first opening 131 are solidified, the support body can be fixedly connected to the pile body 170 based on the solidified filling material in the connecting channel 140.

In the present embodiment, the insertion section 110 is inserted into the hole of the pile 170, so that the insertion section 110 is connected with the pile 170. The structure of the insertion section 110 is not limited. For example, the insertion section 110 may have a circular tube structure or a square tube structure. As an example, the insertion section 110 is a square steel pipe.

It will be understood by those skilled in the art that the insertion section 110 has a filler material in the bore of the stub body 170 prior to insertion into the bore of the stub body 170, at which point the filler material has not solidified and is in a flowable state. Here, the material of the filler is not limited. As an example, the filling body is concrete.

In the present exemplary embodiment, the support section 120 serves to support the carrier 180. The structure of the support segment 120 is not limited. For example, the support segment 120 may have a circular tube structure or a square tube structure. The shape of the support step 120 may be the same as or different from that of the insertion step 110. As

Here, the structure of the carrier 180 is not limited. For example, as shown in fig. 8 and 9, the supporting body 180 may be a floor or a supporting table.

Here, the support section 120 and the insertion section 110 may be two parts of one integral structural member, for example, as shown in fig. 3 and 4. The support section 120 and the insertion section 110 may also be structural members formed by fixedly connecting two structural members, for example, as shown in fig. 1 and 2.

It will be appreciated by those skilled in the art that the support section 120 may be located outside the bore of the post 170, i.e. the bottom side of the support section 120 is flush with the top side of the post 170, in which case the insertion section 110 is just fully located within the bore of the post 170. Of course, parts of the support section 120 may also be inserted into the holes of the pilings 170, as shown in fig. 2.

In the embodiment of the present application, the structure of the first filling chamber 130 is not limited. The first filling chamber 130 may be regular or irregular in shape. For example, the first filling cavity 130 may have a cylindrical structure or a square-cylindrical structure. Here, the first filling cavity 130 may be disposed along a length direction of the insertion section 110.

In the embodiment of the present application, the structure of the first opening 131 is not limited as long as the filling body can enter the first filling cavity 130 through the first opening 131. For example, the first opening 131 may have a cylindrical structure or a square-cylindrical structure.

In the embodiment of the present application, the structure of the connection channel 140 is not limited as long as the filling body can enter the first filling chamber 130 through the connection channel 140. For example, the connection channel 140 may be a channel formed of a closed structure, and may also be a channel formed of a structure having an opening. In a state where the connection passage 140 is formed of a structure having an opening, the connection passage 140 is a non-closed structure. For example, the cross-sectional shape of the connection channel 140 is n-shaped.

In the embodiment of the present application, in a state where the insertion section 110 is inserted into the hole of the pile 170, at this time, the filling material in the hole of the pile 170 is in a flowable state, and the filling material in the hole of the pile 170 can be filled in the first filling cavity 130 through the connection channel 140 and the first opening 131; in a state that the first filling cavity 130, the connecting channel 140 and the filling body in the first opening 131 are solidified, the support body can be fixedly connected with the pile body 170 based on the solidified filling body in the connecting channel 140; since the connecting channel 140 is disposed at the side of the inserting section 110, that is, the connecting channel 140 does not protrude from the surface of the inserting section 110, the inserting section 110 can be smoothly inserted into the hole of the pile 170, thereby reducing the difficulty of inserting the support into the hole of the pile 170 and shortening the time required for inserting the support into the hole of the pile 170; meanwhile, the support body is fixedly connected with the pile body 170 through the filling body solidified in the connecting channel 140, so that the connecting strength between the support body and the pile body 170 can be improved, the structure of the support body can be simplified, and the cost of the support body is reduced.

In some optional implementations of embodiments of the present application, as shown in fig. 5, the insertion section 110 includes: at least two first connectors 111. At least two first connecting elements 111 are connected to the support section 120, the at least two first connecting elements 111 extend in a length direction of the support section 120 to a side away from the support section 120, and the at least two first connecting elements 111 are distributed along a periphery of the support section 120, that is, each first connecting element 111 of the at least two first connecting elements 111 is disposed at the periphery of the support section 120; the at least two first connectors 111 are surrounded to form the first filling cavity 130, that is, all the first connectors 111 located at the periphery of the support section 120 are surrounded to form the first filling cavity 130; the connecting channel 140 is formed between the side surfaces of two adjacent first connectors 111 of the at least two first connectors 111, and one end of each first connector 111 far away from the support section 120 is surrounded to form the first opening 131; so that the connecting channel 140 with a large cross-sectional area is formed by the at least two first connecting members 111, thereby further improving the connecting strength of the support body and the pile body 170, and at the same time, the weight of the support body is reduced by the inserting section 110 formed by the at least two first connecting members 111, thereby reducing the cost of the support body.

In the present embodiment, the structure of the support segment 120 is not limited. As an example, as shown in fig. 1 and 8, the support segment 120 may further include: a second fill cavity 190 and a second opening 191. A second filling cavity 190 is provided in the support section 120 along the length of the support section 120; a second opening 191 is provided at the end of the support section 120 remote from the insertion section 110 for filling the second filling cavity 190 with the filling body; in order to increase the strength of the support section 120.

In this implementation, the structure of the first connecting member 111 is not limited as long as the first connecting member 111 extends to a side away from the supporting section 120 in the length direction of the supporting section 120, and the first connecting member 111 is located at the periphery of the supporting section 120. For example, the cross-sectional shape of the first connecting member 111 may be rectangular or square. As an example, as shown in fig. 5 and 6, the first connecting member 111 has an angle-shaped structure.

Here, the number of the at least two first connectors 111 is not limited. For example, the number of the at least two first connecting members 111 may be two or three. As an example, as shown in fig. 5 and 6, the number of the at least two first connectors 111 is four.

Here, at least two first connectors 111 may be evenly distributed along the circumference of the support section 120, as shown in fig. 6. Of course, the at least two first connecting elements 111 may also be distributed unevenly along the circumference of the support section 120.

In the present embodiment, at least two first connectors 111 may be directly connected to the support segment 120 or may be connected to the support segment 120 through another structural member.

For example, as shown in fig. 1 and 5, the support body may further include: the first partition 150. A first partition 150 is arranged between the support section 120 and the at least two first connections 111; the at least two first connections 111 are connected to the support section 120 via the first partition 150; the first partition 150 and the at least two first connectors 111 enclose the first filling chamber 130, that is, the first partition 150 is a part of a wall of the first filling chamber 130.

In this example, the structure of the first separator 150 is not limited. As an example, as shown in fig. 1 and 2, the first separator 150 is a plate-shaped structure.

In this example, the first portion of the support section 120 may be inserted into the bore of the pile 170 in a state where the at least two first connectors 111 are inserted into the bore of the pile 170. As an example, as shown in fig. 2 and 8, in a state where the at least two first connectors 111 are inserted into the holes of the pile body 170 and the first portion of the bearing segment 120 is inserted into the holes of the pile body 170, the first spacer 150 has a first distance from the top side of the pile body 170, that is, the first spacer 150 is located in the holes of the pile body 170; in this case, since the first portion of the support step portion 120 is also positioned in the hole of the pile 170, the connection strength between the support and the pile 170 can be improved; meanwhile, since the first spacer 150 is also located in the hole of the pile 170, the first spacer 150 can improve the coupling strength between the support and the pile 170 in a state where the filling of the hole of the pile 170 is solidified.

Here, the value of the first distance is not limited. For example, the first distance may be 2 meters.

In this implementation, in order to increase the rigidity of the at least two first connecting members 111, the at least two first connecting members 111 may be fixed by other structural members.

As shown in fig. 5 and 6, the insertion section 110 may further include: a second connector 112. The second connecting pieces 112 are respectively connected with the two adjacent first connecting pieces 111, and the second connecting pieces 112 and the at least two first connecting pieces 111 are surrounded to form the first filling cavity 130; the second connecting member 112 and the side surfaces of the two adjacent first connecting members 111 form the connecting channel 140 therebetween, that is, the second connecting member 112 forms a wall body of the connecting channel 140.

In example one, the structure of the second connection member 112 is not limited. For example, the second connecting member 112 may have a block structure or a strip structure. As an example, as shown in fig. 5 and 6, the second connector 112 has a plate-shaped structure.

In example one, the number of the second connectors 112 corresponds to the number of the first connectors 111. When the number of the first connecting pieces 111 is two, the number of the second connecting pieces 112 may be one, and at this time, one second connecting piece 112 is connected to one side of two first connecting pieces 111; the number of the second connecting members 112 may also be two, and in this case, the two second connecting members 112 may respectively connect two sides of the two first connecting members 111. When the number of the first connecting members 111 is more than two, the number of the second connecting members 112 may be the same as the number of the first connecting members 111, for example, the number of the first connecting members 111 is four, the number of the second connecting members 112 is four, and the four second connecting members 112 are respectively and correspondingly connected to two adjacent first connecting members 111. Of course, the number of the second connection members 112 may be greater than the number of the first connection members 111, and in this case, two adjacent first connection members 111 may be connected by a plurality of second connection members 112. For example, as shown in fig. 5, the two adjacent first connection members 111 are connected by at least two second connection members 112, and the at least two second connection members 112 are uniformly distributed along the length direction of the two adjacent first connection members 111.

In example one, the location of the second connector 112 is not limited. For example, the second connecting member 112 may be located inside at least two first connecting members 111 that are surrounded to form the first filling cavity 130. For another example, as shown in fig. 5 and fig. 6, the second connecting member 112 is located outside the at least two first connecting members 111 to form the first filling cavity 130; under the state that the second connecting piece 112 and the at least two first connecting pieces 111 are inserted into the holes of the pile body 170, the filling bodies in the holes of the pile body 170 can wrap the second connecting piece 112 and the at least two first connecting pieces 111; in a state where the filling body other than the second connecting member 112 and the at least two first connecting members 111 is solidified, the support body can be fixedly connected to the pile body 170 based on the solidified filling body on the peripheral side of the second connecting member 112, thereby further improving the connection strength between the support body and the pile body 170.

In an example one, at least two first connecting members 111 and two second connecting members 112 may be fixedly connected by welding according to actual needs. Of course, the at least two first connectors 111 and second connectors 112 may be replaced by conventional structural members. For example, the insertion section 110 is an angle steel lattice structure, the support section 120 is a steel pipe structure, and the angle steel lattice structure and the steel pipe structure may be directly welded to obtain a support body, or the angle steel lattice structure and the steel pipe structure may be welded to obtain a support body through a plate body; in order to reduce the processing costs.

In some optional implementations of embodiments of the present application, as shown in fig. 3 and 7, the support body may further include: and a through hole. Through holes are provided in the side of the insertion section 110, which communicate with the first filling chamber 130, the through holes forming the connecting channel 140.

In this implementation, the structure of the through-hole is not limited. For example, the through holes may have a spiral structure, and the through holes are spirally distributed along the circumferential direction of the insertion section 110. For another example, the through hole is n-shaped, and the through hole is disposed at the end of the insertion section 110, and in this case, the first opening 131 is a non-closed structure. For another example, the through holes are strip-shaped, and the through holes are distributed along the length direction of the insertion section 110 in a staggered manner, so as to improve the connection strength between the support body and the pile body 170.

In this implementation, the first fill cavity 130 may be located entirely within the insert section 110. Of course, it is also possible for only a part of the first filling chamber 130 to be located in the insertion section 110 and the remaining part of the first filling chamber 130 to be located in the support section 120.

For example, as shown in fig. 9, the first filling cavity 130 may also be disposed within the support section 120; the support body may further include: a second partition 160 and a third opening 132. A second partition 160 is arranged in the first filling chamber 130 at the junction of the insertion section 110 and the support section 120; the second partition and the support section 120 form a first part 1301 of the first filling chamber, and the second partition 160 and the insertion section 110 form a second part 1302 of the first filling chamber. The third opening 132 is disposed at an end of the support segment 120 away from the insertion segment 110, and the third opening 132 is communicated with the first part 1301 of the first filling cavity, and is used for filling the first part 1301 of the first filling cavity with the filling body; in a state where the insertion section 110 is inserted into the hole of the pile 170 and the second part of the support section 120 is inserted into the hole of the pile 170, the second spacer 160 has a second distance from the top side of the pile 170, that is, the second spacer 160 is located in the hole of the pile 170; the filling body in the hole of the pile body 170 can be filled in the second part 1302 of the first filling cavity through the through hole and the first opening 131; in a state that the second part 1302 of the first filling cavity, the through hole and the filling body in the first opening 131 are solidified, the support body can be fixedly connected with the pile body 170 based on the solidified filling body in the through hole; at this time, the support body can be fixedly connected to the pile 170 by the solidified filler body wrapped outside the second spacer 160, thereby further improving the connection strength between the support body and the pile 170.

Here, the structure of the second separator 160 is not limited. As an example, as shown in fig. 9, the second separator 160 may have a plate-shaped structure.

Here, the value of the second distance is not limited. For example, the second distance may be 2 meters.

In the present implementation, the insertion section 110 and the support section 120 may be directly made of a steel tubular structure, and the insertion section 110 is formed by machining a through hole in the insertion section 110 of the steel tubular structure; the second separator 160 may also be formed by welding a plate-like structure inside the steel tubular member in order to reduce the manufacturing cost.
