Description

Technical Field

[0002] The pile foundation cap is a basic platform built on the pile foundation. It is generally made of reinforced concrete structure, which plays the role of supporting and transmitting the load of the pier body to the foundation pile. In the design of various caps, the local compressive stress of the pile top, the bending and shear strength of the cap should be verified.

[0003] The cross-section of a traditional pile foundation pedestal is usually stepped. During the construction process, the method of supporting and pouring layer by layer is usually adopted. However, the method of supporting and pouring layer by layer not only has complicated procedures and prolongs the construction period, but also increases horizontal construction joints. Improper treatment of construction joints will cause corrosion of independent foundation steel bars, thereby affecting structural safety, which needs to be improved. Utility Model Content

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 , Figure 2As shown, a pedestal type independent foundation formwork support system includes a lower layer formwork 1 and an upper layer formwork 2. The lower layer formwork 1 is vertically provided with back ribs 3 all around, and a fixing frame 4 is provided on the back ribs 3 to fix the entire lower layer formwork 1.

[0021] like Figure 1 , Figure 2 As shown, a pair of support rods 5 are horizontally arranged around the upper formwork 2, and the support rods 5 are cross-armed on the lower formwork 1. A broken line reinforcing rod 51 is arranged between the pair of support rods 5 to increase the structural strength and stability of the support rods 5.

[0022] like Figure 1 , Figure 2 As shown, the back rib 3 is provided with an insertion rod 31, and the support rod 5 is provided with a plug hole 52 for the insertion rod 31 to pass through, so as to realize the rapid positioning and limited fixation of the entire upper template 2, thereby increasing the stability of the upper template 2. The upper end of the insertion rod 31 is provided with a hook 32 for pressing the support rod 5, so as to realize the fixation between the lower template 1 and the upper template 2, thereby further increasing the stability of the upper template 2.

[0023] Therefore, by setting up an independent formwork body 11 system, the upper formwork 2 and the lower formwork 1 can be built simultaneously, thereby realizing a one-time pouring construction of the stepped pile foundation pedestal, simplifying the process, shortening the construction period, reducing the impact of horizontal construction joints on structural safety due to corrosion of steel bars.

[0024] like Figure 1 , Figure 2 As shown, the fixing frame 4 includes a horizontal support rod 41, an inclined support rod 42 and an anchor rod 43. The horizontal support rod 41 is horizontally arranged at the lower end of the back rib 3, the upper end of the inclined support rod 42 is arranged at the upper end of the back rib 3, and the lower end is fixed to the horizontal support rod 41, and the anchor rod 43 vertically penetrates the tail end of the horizontal support rod 41.

[0025] Therefore, by providing a fixing frame 4 with high structural strength, during the use of the formwork support system, the structural strength and stability of the upper formwork 2 and the lower formwork 1 can be effectively increased, the impact force of the concrete on them can be overcome, and the construction quality can be ensured.

[0026] like Figure 1 , Figure 2 As shown, the lower template 1 and the upper template 2 each include four plates 11, and a lifting ring 12 is provided at the upper end of the plate 11 to facilitate the lifting of the lower template 1 and the upper template 2. A 45-degree chamfer 13 is provided at both ends of the plate 11, and a connecting plate 14 extending along the direction of the chamfer 13 is provided at both ends of the plate 11, and a bolt 15 is provided through the connecting plate 14.

[0027] like Figure 1 , Figure 2As shown, a diagonal brace 16 is provided between the upper ends of two adjacent plate bodies 11, and screws 17 threadedly connected to the plate bodies 11 are provided at both ends of the diagonal brace 16 to increase the structural strength and stability between the adjacent plate bodies 11, prevent cracks at the connection position, and ensure construction quality.

[0028] Therefore, by setting the modular upper template 2 and lower template 1, it is convenient to assemble the upper template 2 and lower template 1 on site and to transport them. At the same time, the connection between the plates 11 is relatively stable, which can effectively ensure the construction quality.
