Description

Technical Field

[0001] This utility model belongs to the field of pipe pile installation technology, and in particular relates to a quick installation structure for prefabricated pipe pile interfaces. Background Technology

[0002] Large steel frame structures or bridges typically use pipe piles for load-bearing, usually for supporting and constructing large buildings, infrastructure projects, or machinery. Currently, during construction, when the load-bearing structure is installed onto the pipe piles, multiple pipe piles are usually needed to support a single load-bearing structure. However, this process is time-consuming and labor-intensive, affecting the installation speed. Utility Model Content

[0003] In view of this, the present invention aims to overcome the shortcomings of the above-mentioned problems in the prior art and proposes a quick installation structure for prefabricated pipe pile interfaces.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] The precast pipe pile interface quick installation structure includes a support plate and multiple precast pipe piles that are spaced apart and connected together. A connecting bar group is fixed between each pair of adjacent precast pipe piles. Multiple U-shaped limiting grooves are evenly distributed around the circumference at the top opening of the precast pipe pile. The support plate is provided with a plug-in post with a bottom opening for each precast pipe pile. A limiting edge is fixed to the lower part of the outer wall of each plug-in post. A limiting bar is fixed downward at the bottom of the limiting edge corresponding to the limiting groove. The lower part of the plug-in post is inserted into the corresponding precast pipe pile, and the limiting bar is inserted into the corresponding limiting groove. The limiting edge overlaps the upper side of the corresponding precast pipe pile.

[0006] Furthermore, there are four precast pipe piles arranged in a rectangular structure. The support plate includes four side support columns corresponding to the precast pipe piles and a central support column located in the middle of the four side support columns. A web plate is vertically fixed between the central support column and each side support column. An X-shaped wing plate is fixed on each side of the central support column, the four side support columns, and the four web plates. The insertion column is fixed at the bottom of the lower wing plate.

[0007] Furthermore, the lower wing plate is set as a limiting edge on the outer side of the plug-in post, and the limiting rib is fixed between the limiting edge and the plug-in post.

[0008] Furthermore, reinforcing ribs are fixedly connected to the outer walls of the intermediate support column and the side support column between the upper and lower flanges.

[0009] Furthermore, each precast pipe pile is fixed with multiple lifting lugs.

[0010] Furthermore, each precast pipe pile is fixed with lifting lugs at the inner upper part and the outer lower part.

[0011] Furthermore, the connecting bar group includes a first connecting bar and a second connecting bar. Two first connecting bars are fixed horizontally and at intervals between each two adjacent precast pipe piles, and a second connecting bar is obliquely fixed between the two first connecting bars between two adjacent precast pipe piles.

[0012] Furthermore, auxiliary reinforcement bars are horizontally fixed to the upper part of the outer wall of each precast pipe pile.

[0013] Furthermore, each precast pipe pile is vertically fixed with an inverted T-shaped connecting strip below the auxiliary reinforcement on its outer side, and multiple connecting holes are opened on the horizontal section of the connecting strip.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] During construction, the precast pipe pile interface quick installation structure of this utility model allows for the installation of the precast pipe pile in place. A support plate is then overlapped on the upper side of the precast pipe pile. During overlap, the insertion post is aligned and inserted downwards into the corresponding precast pipe pile, and the limiting rib is engaged in the corresponding limiting groove for positioning. This positioning of the support plate on the precast pipe pile enables rapid installation of the precast pipe pile interface, effectively improving construction efficiency.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] As shown in the figure, the precast pipe pile interface quick installation structure includes a support plate 2 and multiple precast pipe piles 1 that are spaced apart and connected together. A connecting bar group is fixed between each pair of adjacent precast pipe piles 1. Multiple U-shaped limiting grooves 11 are evenly opened at the top opening of the precast pipe pile 1 and distributed in the circumferential direction. The support plate 2 is provided with a plug-in post 25 with a bottom opening at each precast pipe pile 1. A limiting edge 26 is fixed at the lower part of the outer wall of each plug-in post 25. A limiting bar is fixed downward at the bottom of the limiting edge 26 corresponding to the corresponding limiting groove 11. The lower part of the plug-in post 25 is inserted into the corresponding precast pipe pile 1, and the limiting bar is inserted into the corresponding limiting groove 11. The limiting edge 26 overlaps the upper side of the corresponding precast pipe pile 1. In this embodiment, during construction, after the precast pipe pile 1 is installed in place, the support plate 2 is overlapped on the upper side of the precast pipe pile 1. During the overlap, the insertion post 25 is aligned and inserted downward into the corresponding precast pipe pile 1, and the limiting bar is inserted into the corresponding limiting groove 11 for limiting. This positions the support plate 2 on the precast pipe pile 1, realizes the rapid installation of the interface of the precast pipe pile 1, and effectively improves the construction efficiency.

[0027] Four precast pipe piles 1 are arranged in a rectangular structure. The support plate 2 includes four side support columns 22 corresponding to the precast pipe piles 1 and a central support column 21 located in the middle of the four side support columns 22. A web plate 23 is vertically fixed between the central support column 21 and each side support column 22. An X-shaped wing plate 24 is fixedly connected to each of the upper and lower sides of the central support column 21, the four side support columns 22, and the four web plates 23. An insert column 25 is fixed to the bottom of the lower wing plate 24. In this embodiment, the central support column 21 and the side support columns 22 can be columnar structures or tubular structures.

[0028] The lower wing plate 24 is configured as a limiting edge 26 on the outer side of the plug post 25, and the limiting rib is fixed between the limiting edge 26 and the plug post 25.

[0029] The middle support column 21 and the side support column 22 are both fixed with reinforcing ribs 27 on their outer walls between the upper and lower wing plates 24.

[0030] Each precast pipe pile 1 is fixed with multiple lifting lugs 12.

[0031] Each precast pipe pile 1 is fixed with a lifting lug 12 on the inner side of the upper part and the outer side of the lower part, so that the lifting lugs 12 of different precast pipe piles 1 are symmetrically arranged, which can ensure the stability of the structure when it is lifted and moved.

[0032] The connecting bar group includes a first connecting bar 13 and a second connecting bar 14. Two first connecting bars 13 are fixed horizontally and at intervals between each two adjacent precast pipe piles 1, and a second connecting bar 14 is fixedly and inclined between the two first connecting bars 13 between two adjacent precast pipe piles 1.

[0033] Each precast pipe pile 1 has an auxiliary reinforcement 15 horizontally fixed to the upper part of its outer side wall. When multiple sets of the precast pipe pile interface quick installation structure need to be installed side by side on the foundation, the alignment of the auxiliary reinforcement 15 of the two adjacent sets of precast pipe pile interface quick installation structures can be used to confirm whether the adjacent precast pipe pile interface quick installation structures are aligned.

[0034] Each precast pipe pile 1 has an inverted T-shaped connecting strip 16 vertically fixed below the auxiliary reinforcement 15 on its outer side. Multiple connecting holes are provided on the horizontal section of the connecting strip 16, and multiple reinforcing blocks 17 are uniformly fixed between the outer wall of the precast pipe pile 1 and the horizontal and vertical sections of the connecting strip 16. During construction, multiple sets of these precast pipe pile interface quick-installation structures can be placed side-by-side. Adjacent sets of these structures can be positioned by threaded steel bars passing through the corresponding connecting holes and secured with nuts.

[0035] A positioning protrusion is provided in the middle of the upper surface of the upper wing plate 24 for positioning the tubular load.

[0036] The working process of this embodiment is as follows:

[0037] During construction, after the precast pipe pile 1 is installed in place, the support plate 2 is overlapped on the upper side of the precast pipe pile 1. When overlapping, the insertion post 25 is aligned and inserted downward into the corresponding precast pipe pile 1, and the limiting bar is inserted into the corresponding limiting groove 11 for limiting. This positions the support plate 2 on the precast pipe pile 1, realizes the rapid installation of the interface of the precast pipe pile 1, and effectively improves the construction efficiency.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
