the outside of precast concrete post is provided with an at least wallboard, every the wallboard respectively with same high position on the holding tank one-to-one sets up, set up along the preformed hole that transversely runs through on the wallboard, be provided with the bolt in the preformed hole, the head of bolt with the wallboard butt, the screw thread end of bolt passes behind the preformed hole with correspond in the holding tank interior screw-thread fit on the built-in fitting.

Further, the embedded part is a sleeve, the sleeve is fixedly connected with the groove wall of the accommodating groove, and the internal thread is located at one end, close to the corresponding wallboard, of the sleeve.

Further, the preformed hole is formed in one end, close to the precast concrete column, of the wallboard.

Further, a spring washer is arranged between the head of the bolt and the wallboard, one end of the spring washer is abutted against the head of the bolt, and the other end of the spring washer is abutted against the wallboard.

Further, the head of the bolt is in the shape of an external hexagonal polygon.

The utility model has the advantages that: the utility model provides a pair of connection structure of precast concrete post and wallboard couples together precast concrete post and wallboard in same high position, has unified fluting and trompil position in precast concrete post and the wallboard to make the quantity of built-in fitting and embedding position be clear and definite, and then reduced the product specification type of precast concrete post and wallboard, improved industrialization efficiency greatly.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In this application, unless expressly stated or limited otherwise, the terms "connected" and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the description of the present application, it is to be understood that the terms "longitudinal," "lateral," "horizontal," "top," "bottom," "upper," "lower," "inner" and "outer" and the like are used in the orientation or positional relationship shown in the drawings, which are used for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1-4, the utility model provides a connection structure of precast concrete post and wallboard, including precast concrete post 10. The precast concrete column 10 is provided with at least one accommodating groove 11 extending inwards in the transverse direction on the outer peripheral surface of the column at the same height position. An embedded part 20 is fixedly mounted on the inner wall of each accommodating groove 11, and internal threads extending inwards in the transverse direction are formed on the embedded part 20.

The outside of precast concrete post 10 is provided with an at least wallboard 30, and every wallboard 30 sets up with holding tank 11 on the same high position one-to-one respectively. The wall plate 30 is provided with a preformed hole 31 which runs through along the transverse direction, a bolt 40 is arranged in the preformed hole 31, the head 41 of the bolt 40 is tightly abutted against the wall plate 30, and the threaded end 42 of the bolt 40 is matched with the internal thread on the embedded part 20 in the corresponding accommodating groove 11 after passing through the preformed hole 31 along the transverse direction. When the precast concrete column 10 and the wall plate 30 are installed, the bolt 40 passes through the preformed hole 31 on the wall plate 30 and is screwed into the embedded part 20 in the precast concrete column 10 to form a whole, and the force is jointly applied.

Preferably, the precast concrete column 10 is a rectangular parallelepiped structure, and can be connected to one to four wall panels 30, respectively, and after connection, the column is in a shape of "a straight line", "L", "T" and "cross", and fig. 2 shows only a connection state of "cross".

Because the utility model discloses be connected precast concrete post 10 and wallboard 30 at same high position, consequently unified the fluting and the trompil position in precast concrete post 10 and the wallboard 30 to make the quantity and the embedding position of built-in fitting 20 clear and definite, just so reduced the product specification type of precast concrete post 10 and wallboard 30, improved industrialization efficiency greatly.

In one embodiment, the embedded part 20 is a sleeve, an end of the sleeve away from the corresponding wall plate 30 is an anchoring end 21, the anchoring end 21 is fixedly connected with a groove wall of the receiving groove 11, and the internal thread is located at an end of the sleeve close to the corresponding wall plate 30. The use of a sleeve as the embedment 20 makes the installation of the embedment 20 easier.

In one embodiment, the prepared hole 31 is opened at one end of the wall panel 30 near the precast concrete column 10. Since the bolts 40 are installed in the prepared holes 31, the length of the bolts 40 can be reduced, and the deflection is reduced, so that the connection of the precast concrete column 10 and the wall panel 30 is more stable.

In one embodiment, a spring washer 43 is disposed between the head 41 of the bolt 40 and the wall plate 30, with one end of the spring washer 43 abutting the head 41 of the bolt 40 and the other end abutting the wall plate 30. The elastic action of the spring washer 43 prevents the bolt 40 from loosening.

In one embodiment, the head 41 of the bolt 40 is externally hexagonal.
