Abstract
The invention discloses a wood-concrete combined structured joint connecting form. The wood-concrete combined structured joint connecting form comprises a concrete pile, a wooden column, a steel plate connector and self-tapping screws. The steel plate connector is arranged between the wooden column and the concrete pile and comprises an upper thin steel plate and a lower steel cushion plate, wherein the thin steel plate is perpendicularly welded to the upper surface of the steel cushion plate, the steel cushion plate is arranged between the bottom of the wooden column and the concrete pile, and the thin steel plate is arranged inside the wooden column; the wooden column is provided with a plurality of the self-tapping screws, which penetrate and fix the thin steel plate; every self-tapping screw comprises a screw body and a screw end, the diameter of the screw end is smaller than that of the screw body, the screw end is provided with a high-strength screw case, the external threads of the screw end are matched with the internal threads of the high-strength screw case, the diameter of the high-strength screw case is identical to that of the screw body, and the high-strength screw case is screwed onto the screw end and forms a whole together with the self-tapping screw. The wood-concrete combined structured joint connecting form simplifies construction processes, reduces the cost, improves the construction efficiency and can be well applied to practical engineering.
Description
Technical field
The present invention relates to construction work new structure, specifically refer to a kind of wood-concrete composite structure node type of attachment.
Background technology
In wooden concrete composite structure architectural design, compared with the wooden construction developed countries such as China and America and Europe, there is larger gap, therefore implement correlative study at wooden concrete composite structure design field very necessary.It is the problems referred to above key technologies in actual applications that the node of wood concrete composite structure connects, the node improving wooden concrete composite structure connects can advance the application of wooden concrete composite structure in multistoried building building, and ensures its safety and stability in use.
The current research about wood-concrete composite structure node connection is less, and existing joint form, makes loaded down with trivial details, and need fine design when being applied to wood-concrete composite structure, production efficiency is low.
Summary of the invention
The object of the invention is for prior art Problems existing, a kind of wood-concrete composite structure node type of attachment is provided.
The technical solution used in the present invention is: a kind of wood-concrete composite structure node type of attachment, comprise concrete pile, pin, steel plate connector and tapping screw, steel plate connector is provided with between described pin and concrete pile, steel plate connector comprises the steel sheet on top and the billet of bottom, steel sheet is vertically welded in above billet, billet is bottom pin and between concrete pile, steel sheet is positioned at pin, pin is provided with multiple tapping screw, tapping screw bores steel sheet and is fixed;
Described tapping screw comprises nail body and nail end, the diameter of nail end is less than the diameter of nail body, nail end is provided with high-strength screw cover, the internal thread that the external screw thread of nail end and high-strength screw overlap matches, the diameter of high-strength screw cover is identical with the diameter of nail body, and high-strength screw cover is spun on nail end and above becomes as a whole with tapping screw.
The present invention adopts the self-drilling connection wood-concrete joint with special screw cover, special screw cover utilizes high-strength material to make, steel sheet can be bored, after tapping screw is pierced, again special screw cover is backed out in the other direction, to reuse, more to adapt to the development that modern concrete-wooden combination construction interior joint connects.
The form of tapping screw of the present invention is divided into two parts: tapping screw (head diameter diminishes, and is connected to overlap with screw), special screw cover (have high strength, can bore steel sheet, be reusable).
Beneficial effect: the present invention bores under steel sheet exists difficulty situation at common tapping screw, the tapping screw being provided with high-strength screw cover by design end completes the saturating steel sheet of brill, again after tapping screw pierces, special screw cover is oppositely backed out for recycling, this avoid whole tapping screw and all use high-strength material, effectively can save cost.This invention simplifies the step of construction, reduce cost, improve efficiency of construction, feasibility is strong, can be advantageously applied in Practical Project.

Fig. 2 is concrete of the present invention-wooden construction node connection space schematic diagram;
Fig. 3 is the floor map of tapping screw of the present invention;
Fig. 4 is the space schematic diagram of tapping screw of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As Figure 1-4: a kind of wood-concrete composite structure node type of attachment, comprise concrete pile 1, pin 2, steel plate connector and tapping screw 5, steel plate connector is provided with between described pin 2 and concrete pile 1, steel plate connector comprises the steel sheet 4 on top and the billet 3 of bottom, steel sheet 4 is vertically welded in above billet 3, billet 3 is bottom pin 2 and between concrete pile 1, steel sheet 4 is positioned at pin 2, pin 2 is provided with multiple tapping screw 5, tapping screw 5 bores steel sheet 4 and is fixed; Described tapping screw 5 comprises nail body and nail end, the diameter of nail end is less than the diameter of nail body, nail end is provided with high-strength screw cover 6, the internal thread that the external screw thread of nail end and high-strength screw overlap 6 matches, the diameter of high-strength screw cover 6 is identical with the diameter of nail body, and it is upper as a whole with tapping screw 5 one-tenth that high-strength screw cover 6 is spun on nail end.
It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.The all available prior art of each ingredient not clear and definite in the present embodiment is realized.
