Disclosure of Invention

In order to overcome the problem that above-mentioned prior art exists, the utility model aims to provide a mortise and tenon structure of cross wall constructional column can solve the concrete constructional column and pour the honeycomb pitted surface, the constructional column mortar joint problem of casting that produces, has effectively restricted the constructional column and has twisted round the stress loss who causes each way, and the interconversion and the support form firm constructional column structure, have advantages such as stable reasonable, simple to operate, low cost and safe and reliable.

In order to achieve the above object, the utility model discloses a technical scheme be:

a mortise and tenon structure of a cross-shaped wall constructional column comprises a precast concrete component 1, wherein a first mortise 2 and a first tenon 3 which are crossed are arranged in the middle of the top of the precast concrete component 1, and mortises 4 are uniformly distributed on the first mortise 2 and the first tenon 3; and two sides of the top of the precast concrete member 1 are respectively provided with a second mortise 5 and a second tenon 6, and two sides of the bottom of the precast concrete member 1 are respectively provided with a third tenon 8 and a third mortise 7 which are matched with the second mortise 5 and the second tenon 6.

The first mortise 2 and the first tenon 3 are both in the shape of an isosceles right triangle.

The mortise 4 is cylindrical.

Longitudinal ribs 9 penetrate through the mortise 4.

The precast concrete members 1 are connected in a manner of tenon-and-mortise connection in pairs and are built and superposed together with the building blocks 10 layer by layer to form the cross-shaped wall constructional column 11.

The beneficial effects of the utility model reside in that: by utilizing the characteristics of the tenon-and-mortise structure, the problems of honeycombs, unclear pouring and the like in large-volume concrete pouring of the constructional column are solved; the mortises and the tenons on the precast concrete component 1 are mutually occluded, so that the mortises 4 at the upper and lower parts of the precast concrete component 1 are mutually aligned, and the longitudinal ribs 9 penetrate through the occluded parts of the first mortises 2 and the second tenons 3 from the mortises 4, so that the mortises and the tenons are connected into a whole, and the verticality of the cross-shaped wall constructional column 11 in the construction process is ensured; the integrity and safety of the cross-shaped wall constructional column 11 in long-term use are improved.

To sum up, the utility model has the advantages of stable in structure is reasonable, simple to operate, low cost and safe and reliable.
