Please refer to fig. 1 to 3. FIG. 1 is a schematic diagram of an assembly structure between a concrete support pile and a section steel assembly according to an embodiment of the present utility model; FIG. 2 is an elevation view of the mating structure between the medium-sized steel pre-buried connection assembly of FIG. 1 and the reinforcing steel bar, concrete layer; fig. 3 is a side view of fig. 2.

In a specific embodiment, the profiled bar pre-buried connection assembly provided by the utility model comprises a pre-buried steel plate 11 fixedly connected to the inner steel bar 101 of the concrete support pile, and further comprises a limiting sheath 12 connected to the inner steel bar 101 of the concrete support pile, wherein the middle part of the limiting sheath 12 is provided with a limiting hole 121 which penetrates through the concrete layer 102 of the concrete support pile from inside to outside and can be inserted by the bracket support 201, and the pre-buried steel plate 11 is positioned in the limiting hole 121.

In the assembly application process, before the concrete pouring operation of the concrete support pile is implemented, the embedded steel plate 11 is fixedly connected to the steel bar 101 in the support pile, then a sufficient accommodating space is provided for the embedded steel plate 11 by utilizing the limiting hole 121 structure formed in the limiting sheath 12, after the concrete attention operation is finished, the limiting hole 121 structure can ensure that the embedded steel plate 11 is directly communicated with the external environment of the pile body 10 of the concrete support pile, so that a worker stretches one end of the bracket support 201 into the limiting hole 121, and the end of the bracket support 201 is reliably welded and fixed with the embedded steel plate 11, thereby completing the reliable connection and assembly between the bracket support 201 and the pile body 10 of the concrete support pile. The whole connection process does not need to carry out operations such as breaking, digging and the like on the concrete layer 102 of the concrete support pile after pouring operation is finished, so that the structural integrity of the concrete support pile and the integral structural strength of the concrete support pile are guaranteed, meanwhile, the assembly operation difficulty between the bracket support frame 201 and the pile body 10 of the concrete support pile is effectively reduced, the labor intensity of workers is correspondingly reduced, the operation efficiency is correspondingly improved, the connection structure between the bracket support frame 201 and the concrete support pile is obviously optimized, the connection assembly between the concrete support pile and building main structural members such as profile steel is more stable and reliable, and the building quality is correspondingly improved.

Specifically, as shown in fig. 1, the side part of the pile body 10 of the concrete support pile is connected with a section steel assembly 20, and a triangular diagonal bar supporting structure is realized between the bottom of the section steel assembly 20 and the pile body 10 of the concrete support pile through a bracket supporting frame 201, so that the structural support of the section steel assembly 20 by the concrete support pile is ensured, and the main structural stability of the section steel assembly 20 is ensured.

Generally, a plurality of inclined rod-shaped supports may be required to be arranged in the same bracket support 201, and then the pile body 10 of the concrete support pile may be correspondingly provided with steel pre-buried connection assemblies in the same number as the rod-shaped supports, so as to ensure that the end parts of each inclined rod-shaped support of the bracket support 201 are connected with the pre-buried steel plates 11 in a one-to-one correspondence manner, thereby ensuring the stability of the assembly structure between the concrete support pile and the bracket support 201, optimizing the stress distribution between the bracket support 201 and the related connection members, and improving the overall layout and construction quality of the corresponding building.

In actual operation, the embedded steel plates 11 and the steel bars 101 of the concrete support pile can be fixedly connected through mechanical connectors such as bolts or clamping plates, or can be directly welded, assembled and fixed. The assembly form between the embedded steel plate 11 and the steel bar 101 of the concrete support pile can be flexibly selected and adjusted by staff according to the specific working condition requirements. In principle, the assembly requirements of the steel section embedded connection assembly can be met as long as the reliable connection between the embedded steel plate 11 and the steel bar 101 of the concrete support pile can be ensured.

Further, a protective cover plate 122 is encapsulated at the outer end orifice of the limiting hole 121. The protection cover plate 122 can further prevent the embedded steel plate 11 positioned in the limiting hole 121 from being blocked by the concrete layer 102 in the concrete pouring process, ensure that the embedded steel plate 11 has sufficient assembly space and connection structure allowance, only need to detach or directly break and remove the protection cover plate 122 after the concrete layer 102 is poured and formed, and re-expose the embedded steel plate 11 so as to implement subsequent bracket support frame 201 assembly operation, ensure the reliable connection of corresponding structural components such as profile steel and optimize corresponding building quality.

On this basis, the outer wall of the protective cover plate 122 is coplanar with the outer wall of the pile body 10 of the concrete support pile. This kind of outer wall coplanarity adaptation structure can suitably reduce the adverse effect of protection cover plate 122 to concrete pouring process and concrete layer 102 shaping effect of concrete support stake, avoids the component structure to interfere to make the external structure of concrete support stake after pouring the shaping more regular, whole assembly structure is more steady reliable.

Of course, in practical assembly application, the outer wall of the protective cover plate 122 can also protrude from the outer wall of the pile body 10 of the concrete support pile, so that the operation difficulty in breaking and removing the protective cover plate 122 is further reduced, the workload in assembly connection between the bracket support 201 of the profile steel assembly 20 and the concrete support pile is reduced, the corresponding connection assembly layout is optimized, and the overall construction quality of the building is correspondingly improved.

In addition, the inner wall of the limit sheath 12 and the inner wall of the protective cover plate 122 are in clearance fit with the embedded steel plate 11 to form a buffer protection cavity 123. The buffer protection cavity 123 not only can further ensure that the periphery of the embedded steel plate 11 has sufficient arrangement space, but also can provide a certain deformation allowance for the limit sheath 12, so that when concrete pouring is implemented, if the limit sheath 12 is subjected to structural impact to deform, the deformation position of the limit sheath 12 can be concave and occupy the space of the buffer protection cavity 123, so that the limit sheath 12 is prevented from directly causing rigid contact or structural impact to the embedded steel plate 11 after deformation, and the structural stability of the embedded steel plate 11 is further ensured.

On this basis, the buffer protection chamber 123 is filled with a buffer layer. The buffer layer can fill the buffer protection cavity 123 to provide a certain structural support for the limit sheath 12, and provide proper buffer for the limit sheath 12 when the limit sheath 12 is subjected to structural impact, so as to further avoid rigid contact or structural impact between the limit sheath 12 and the embedded steel plate 11, thereby ensuring that the limit sheath 12 is more fully and reliably used for protecting the structure of the embedded steel plate 11.

In actual operation, the buffer layer and the protective cover plate 122 can be broken and removed together, so that the main structure of the embedded steel plate 11 is exposed, and the subsequent alignment welding assembly of the bracket support 201 and the embedded steel plate 11 is facilitated.

More specifically, the buffer layer is an XPS (extruded polystyrene foam) material layer. The XPS material has high mechanical strength, good heat insulation performance, strong high-temperature and high-humidity environment tolerance, can fully meet the operation requirement of the concrete construction process, has strong adaptability to the building environment, can greatly improve the working condition adaptability of the profile steel embedded connecting assembly, and ensures the structural performance of a buffer layer.

On the other hand, the protective cover plate 122 is a thin iron plate or a plastic plate. The thin iron plate or the plastic plate is thinner in structure and easy to break, detach and remove, so that the operation difficulty of the protective cover plate 122 during detachment can be further reduced, the labor intensity of workers is reduced, the operation efficiency is improved, and the removal effect of the protective cover plate 122 is optimized.

Of course, in a specific practical application, other material parts can be selected for the protective cover plate 122 according to the material application and assembly adaptation requirements under different working conditions, and a worker can flexibly select and adjust according to the practical working condition requirements. In principle, the machining and forming requirements of the profile steel embedded connecting assembly can be met.

In addition, the protective cover plate 122 and the limiting sheath 12 are an integral thin iron piece. The integral structure helps to further optimize the structural consistency of the protective cover plate 122 and the limiting sheath 12, and improves the assembly effect of the corresponding components.

In addition, similar to the foregoing, the protecting cover plate 122 and the limiting sheath 12 may be made of plastic, and in practical application, specific materials of the protecting cover plate 122 and the limiting sheath 12 may be flexibly selected and adjusted according to actual working condition requirements, but it should be ensured that the protecting cover plate 122 and the limiting sheath 12 obtained by material selection processing are convenient to break, detach and remove, so as to avoid adverse effects on connection operation between the embedded steel plate 11 and the bracket support 201.

During practical assembly application, the profile steel assembly 20 is arranged at the side part of the pile body 10, the bracket support 201 is used as a main support part between the main structure of the profile steel assembly 20 and the pile body 10, one end of each rod piece which is obliquely arranged in the bracket support 201 is in one-to-one corresponding alignment and fixed connection with each embedded steel plate 11 of the profile steel embedded connection assembly, and the other end of each rod piece is connected with the profile steel main structure.

It is known that the profile steel embedded connecting assembly comprises an embedded steel plate fixedly connected to the inner steel bar of the concrete support pile and a limiting sheath connected to the inner steel bar of the concrete support pile, wherein the middle part of the limiting sheath forms a limiting hole penetrating through the concrete layer of the concrete support pile from inside to outside and allowing the bracket support frame to be inserted, and the embedded steel plate is positioned in the limiting hole. In the assembly application process, before the concrete pouring operation of the concrete support pile is implemented, the embedded steel plate is fixedly connected to the steel bars inside the support pile, then a limiting hole structure formed inside the limiting sheath can be utilized to provide sufficient accommodating space for the embedded steel plate, after the concrete attention operation is finished, the limiting hole structure can ensure that the embedded steel plate is directly communicated with the external environment of the concrete support pile, so that a worker stretches one end of the bracket support frame into the limiting hole, and the end of the bracket support frame is reliably welded and fixed with the embedded steel plate, thereby completing the reliable connection assembly between the bracket support frame and the concrete support pile. The whole connection process does not need to carry out operations such as breaking, digging and the like on a concrete layer of the concrete support pile after pouring operation is finished, so that the structural integrity of the concrete support pile and the integral structural strength of the concrete support pile are guaranteed, meanwhile, the assembly operation difficulty between the bracket support frame and the concrete support pile is effectively reduced, the labor intensity of workers is correspondingly reduced, the operation efficiency is correspondingly improved, the connection structure between the bracket support frame and the concrete support pile is obviously optimized, the connection assembly between the concrete support pile and a structural steel and other building main structural members is more stable and reliable, and the building quality is correspondingly improved.
