Embodiment Construction

[0049] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0050] see Figure 1 to Figure 9 , the embodiment provides a concrete prefabricated pile connecting device. Such as figure 1 and figure 2 As shown, it is a sectional view of two precast concrete piles 200 connected end to end by the precast concrete pile connection device 100 in the embodiment, figure 2 for figure 1 In the partial enlarged view of part A, the precast concrete pile connecting device 100 is arranged on two opposite end faces of the two precast concrete piles 200, so as to connect the two precast concrete piles fixedly. Such as figure 2 As shown, one end of the concrete precast pile 200 is provided with an end plate 210, and the other end is provided with an end plate 220. The concrete precast pile connection dev...

Abstract

The invention relates to the technical field of building materials, and discloses a connection device of concrete precast piles and a concrete pile foundation. The connection device of the concrete precast piles is used for connecting two concrete precast piles, and includes connecting lock blocks and connecting pin rods, wherein the connecting lock blocks are pre-embedded in one end faces of theconcrete precast piles, and the connecting lock blocks include more than two lock blocks which are arranged at intervals along the circumference to form lock holes, and the bottoms of the two or morelock blocks are fixedly connected with each other; pin heads matched with the lock holes are arranged at one ends of the connecting pin rods, and first connecting mechanisms connected with the end faces of the other concrete precast pile are arranged at the other ends of the connecting pin rods. According to the connection device of the concrete precast piles and the concrete pile foundation, thebottoms of the lock blocks are fixedly connected with one another, the infirm connection of the connecting pin rods and the connecting lock blocks caused by the sliding of the lock blocks can be effectively prevented, the connection reliability of the connecting lock blocks and the connecting pin rods is improved, and the reliability of a concrete precast pile project is ensured.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a concrete prefabricated pile connection device and a concrete pile foundation. Background technique [0002] Prefabricated concrete piles have the advantages of high structural strength and high construction efficiency, and are widely used in building foundation construction. In order to enable the concrete prefabricated piles to be inserted deep into the ground, during construction, more than two concrete precast piles need to be used in series from end to end through a connecting device. The connecting device generally includes a lock hole formed by more than two lock blocks, and a pin rod adapted to the lock hole. However, in the existing connecting device, each lock block is in a separated state and can move relatively. Therefore, when the pin bar is connected to the lock block, the separated lock block may slip relative to each other, causing the lock block to b...
