Problems solved by technology

[0004] But there are two big defects in this scheme, one is that the top plate is provided with the groove (1-2) that is square shape, and its corresponding surface is provided with retaining groove (1-3), is also provided with locking through hole (1-1 ), the thickness of this position on the top plate is obviously thinned, and the strength of this position is weakened. This kind of top plate is easily damaged or even broken during handling, and it is also easy to break during application; Long-strip locking rod (2-1) is supported, and its support strength is relatively thin, and it is prone to cracking and damage after installing the roof or after being subjected to long-term vibration

Embodiment 1

[0049] like figure 1 , 2 As shown in the figure, a prefabricated pile cap for composite foundation is prefabricated, the pile cap includes a top plate 1 and a fixing kit 2 supported on the lower side of the top plate 1, and the fixing kit 2 is used to be sleeved on the upper end surface of the pipe pile 3 In this embodiment, a ring-shaped groove 4 is provided on the lower surface of the top plate 1, and the groove walls of the ring-shaped groove 4 are inclined to both sides; this inclined groove is convenient for installation.

[0050] The fixing kit 2 includes a main board 5, the upper surface of the main board 5 is provided with a ring-shaped tenon 6, and the ring-shaped

[0051] The side surface of the tenon 6 is inclined to both sides, and the ring-shaped tenon 6 matches the size of the ring-shaped groove 4, so that the ring-shaped tenon 6 can be embedded in the ring-shaped groove 4; The lower surface of the main board 5 is provided with a fixed sleeve 7, the upper surfa...

Embodiment 2

[0054] like figure 2 , 3 , 4, the stable support structure of the pile cap mainly comes from the reinforced keel 12 in the fixing kit 2. The fixing kit 2 is a reinforced keel concrete member, wherein the reinforced keel 12 includes tenon stirrups 13, tenon supports 14, upper main board stirrups 15, lower main board stirrups 16, upper main board straight bars 17, and lower main board straight bars. Ribs 18 , main plate column ribs 19 , upper sleeve stirrups 20 , lower sleeve stirrups 21 , sleeve column ribs 22 and sleeve diagonal ribs 23 .

[0055] The upper main plate stirrup 15 and the lower main plate stirrup 16 are circular stirrups of the same size, and the ends of several upper main plate straight bars 17 are welded to the upper main plate stirrup 15 through the center of the upper main plate stirrup to form the upper main plate steel mesh 24, the two ends of several lower main plate straight bars 18 are welded on the lower main plate stirrups 16 by the center of the c...

Abstract

An assembly type pile cap for a composite foundation belongs to the technical field of building construction and comprises a top plate and a fixing suite of the top plate, the top plate is provided with an annular-strip-shaped groove, and the fixing suite comprises a main plate, an annular-strip-shaped tenon on the upper surface of the main plate and a fixing sleeve on the lower surface of the main plate. A steel bar keel of the fixing suite comprises a main plate steel bar cage, an annular tenon steel bar cage on the upper side of the main plate steel bar cage and a sleeve steel bar cage on the lower side of the main plate steel bar cage, the annular tenon steel bar cage is formed by welding tenon stirrups to the vertexes of triangular tenon supporting frames, and the sleeve steel bar cage is formed by welding lower sleeve stirrups to the vertexes of right triangle supporting and abutting frames. The invention has the beneficial effects that the top plate is only provided with the annular strip-shaped groove, so that the strength of the top plate is effectively ensured; the triangular tenon supporting frame and the right triangle supporting and abutting frame can improve the strength of the keel, the triangular tenon supporting frame and the right triangle supporting and abutting frame form a mutually-coordinated stable supporting structure with the main plate reinforcement cage, the fixing sleeve is stably connected with the pipe pile, the annular-strip-shaped tenon is stably connected with the top plate, and the overall quality of the pile cap is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an assembled pile cap for composite foundations. Background technique [0002] Concrete pipe piles are an effective form of soft foundation treatment. The pipe piles are inserted into the soil through the vibration or static pressure of the pile driver and reach the bearing layer. After the insertion is completed, the pile cap is poured at the top of the pile. Lay keel and gravel to form a composite foundation, so as to achieve the effect of strengthening the soft foundation and reducing the foundation settlement to meet the needs of later construction. The existing prefabricated piles have the advantages of high production efficiency, stable quality and relatively low cost due to the use of construction industrialization methods, and the construction period can be significantly shortened. At present, the pile caps of prefabricated piles have two methods: cast-in-p...
