Description

Technical Field

[0001] This utility model relates to the field of prefabricated structure technology, specifically to a prefabricated composite steel reinforcement processing shed foundation structure. Background Technology

[0002] A rebar processing shed is a dedicated area on a construction site for rebar processing (such as straightening, bending, and welding). It typically covers raw material storage areas, processing areas, and semi-finished product storage areas. Its core function is protection, preventing injuries from falling objects and protecting materials and equipment.

[0003] Traditional cast-in-place concrete foundations have long construction cycles, requiring on-site formwork, pouring, and curing. They are easily affected by weather and have a high material waste rate. Meanwhile, some prefabricated foundations use a single connection method (such as bolted connections only), which has weak shear resistance and is prone to connection failure due to equipment vibration or load eccentricity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated composite steel reinforcement processing shed foundation structure, which solves the problems of long construction cycles, the need for on-site formwork, pouring and curing, susceptibility to weather conditions, and high material waste rates associated with traditional cast-in-place concrete foundations. Furthermore, some prefabricated foundations use a single connection method, resulting in weak shear resistance and susceptibility to connection failure due to equipment vibration or load eccentricity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated composite steel reinforcement processing shed foundation structure, comprising multiple prefabricated foundation slabs arranged in a rectangular array, each of the four corners of the prefabricated foundation slabs having a hoisting hole for hoisting, and a combination unit provided between the multiple prefabricated foundation slabs, wherein the combination unit is connected to the multiple prefabricated foundation slabs through the hoisting holes, thereby strengthening the connection between the multiple prefabricated foundation slabs.

[0006] Preferably, anchor bolts are pre-embedded in multiple precast foundation slabs in the middle, and the anchor bolts are used for the installation of the columns of the steel bar processing shed.

[0007] Preferably, a through-type reserved wire groove is provided on multiple prefabricated foundation slabs in the middle, and a connecting groove is provided near the anchor bolts of the reserved wire groove.

[0008] Preferably, the precast foundation slab may have embedded equipment components, which may be configured as embedded sleeves or bolts.

[0009] Preferably, the combined unit includes an edge connector and an intermediate connector.

[0010] Preferably, the edge connector includes a connecting flat steel and an edge connecting post. The connecting flat steel is disposed between two adjacent precast foundation slabs and above the lifting hole at the edge. The edge connecting post is inserted between the connecting flat steel and the lifting hole.

[0011] Preferably, the intermediate connecting member includes a bottom flat steel, an upper flat steel and an intermediate connecting column. The bottom flat steel and the upper flat steel are arranged between four adjacent precast foundation plates and above the middle hoisting hole. The upper flat steel is arranged above the bottom flat steel, and the intermediate connecting column is inserted between the bottom flat steel, the upper flat steel and the hoisting hole.

[0012] This utility model discloses a prefabricated composite steel reinforcement processing shed foundation structure, which has the following beneficial effects:

[0013] This prefabricated composite steel reinforcement processing shed foundation structure features prefabricated foundation slabs produced in the factory and directly hoisted on site. Compared to traditional cast-in-place foundations, this shortens the construction period. The composite units are rapidly assembled using standardized connectors, reducing human error and comprehensively optimizing structural performance. The edge connectors and intermediate connectors form a three-dimensional force-bearing system, enhancing the foundation's bending bearing capacity and lateral displacement resistance. The double-layer flat steel intermediate connectors effectively distribute the load, resist uneven settlement, and improve overall stability.

[0021] This utility model discloses a prefabricated composite steel bar processing shed foundation structure.

[0022] According to the appendix Figure 1-3 As shown, it includes multiple prefabricated foundation slabs 1, which are arranged in a rectangular array. Each of the four corners of the prefabricated foundation slabs 1 has a hoisting hole 11 for hoisting. A combination unit 2 is provided between the multiple prefabricated foundation slabs 1, and the combination unit 2 is connected to the multiple prefabricated foundation slabs 1 through the hoisting hole 11, which can strengthen the connection between the multiple prefabricated foundation slabs 1.

[0024] Precast foundation slab 1 is manufactured in the factory and directly hoisted on site, which shortens the construction period compared to traditional cast-in-place foundations. The combined unit 2 achieves rapid assembly through standardized connectors, reducing human error and comprehensively optimizing structural performance. The edge connector 21 and the middle connector 22 form a three-dimensional force system, which improves the foundation's bending bearing capacity and lateral displacement resistance. The middle connector 22 with double-layer flat steel effectively disperses the load, resists uneven settlement, and improves overall stability.

[0025] Furthermore, anchor bolts 12 are pre-embedded in multiple precast foundation slabs 1 in the middle, and the anchor bolts 12 are used for the installation of the steel bar processing shed columns.

[0029] Specifically disclosed, the edge connector 21 includes a connecting flat steel 211 and an edge connecting post 212. The connecting flat steel 211 is disposed between two adjacent precast foundation slabs 1 and above the lifting hole 11 at the edge.

The upper flat steel 222 is arranged above the bottom flat steel 221, and the intermediate connecting column 223 is inserted between the bottom flat steel 221, the upper flat steel 222, and the lifting hole 11.

[0031] The factory-precast concrete slab has four pre-drilled lifting holes 11 at the corners, pre-embedded anchor bolts 12 and pre-drilled cable trays 13 in the middle area, and optional equipment embedded parts 15 at the edges. The lifting holes 11 enable rapid positioning through mechanized lifting, the anchor bolts 12 are used for column installation, and the pre-drilled cable trays 13 and connecting grooves 14 enable concealed laying of pipelines.

[0032] Edge connector 21 uses connecting flat steel 211 to bridge the lifting holes 11 on the edges of two adjacent plates, and edge connecting column 212 is inserted and fixed to enhance the edge's shear resistance. Intermediate connector 22 uses bottom flat steel 221 and upper flat steel 222 to bridge the lifting holes 11 in the center of four plates, and intermediate connecting column 223 is inserted to form a three-dimensional truss structure, which distributes the load and improves the overall rigidity.

[0033] Precast foundation slab 1 is manufactured in the factory and directly hoisted on site, which shortens the construction period compared to traditional cast-in-place foundations. The combined unit 2 achieves rapid assembly through standardized connectors, reducing human error and comprehensively optimizing structural performance. The edge connector 21 and the middle connector 22 form a three-dimensional force system, which improves the foundation's bending bearing capacity and lateral displacement resistance. The middle connector 22 with double-layer flat steel effectively disperses the load, resists uneven settlement, and improves overall stability.
