Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the present application, the following descriptions are made in conjunction with the accompanying drawings and embodiments.

Referring to fig. 1 to 7, the anchor bolts 10 have an L-shaped structure, and four anchor bolts 10 are arranged at intervals between a vertical part 10a and a horizontal part 10 b. When the foundation bolt 10 is constructed, the horizontal part and the bottom of the vertical part 10a are cast in the foundation in an embedded manner, the middle part and the upper part of the vertical part 10a extend out of the surface of the foundation to be connected with subsequent prefabricated parts in a positioning manner, and the foundation and the prefabricated parts are connected and fastened in a positioning manner through the foundation bolt 10.

For rag bolt 10 be convenient for connect it and improve its positioning accuracy when the construction, this application positioner includes:

the vertical positioning assembly is used for fixedly connecting the bottoms of the vertical parts 10a of the foundation bolts 10 and connecting the four foundation bolts 10 into an integral structure, so that the relative positioning between the foundation bolts 10 is improved, and the connection precision between a later stage and a prefabricated part is ensured.

And the connecting assembly is used for connecting the foundation bolts 10 which are connected into an integral structure with binding steel bars through the vertical positioning assembly, positioning and fastening the foundation bolts 10 and the binding steel bars, keeping the relative positioning of the four foundation bolts 10 and the foundation, and simultaneously enabling the tops of the foundation bolts 10 to stretch out of the binding steel bars so as to ensure the smooth connection and connection precision of the foundation bolts and the prefabricated parts after the foundation is poured.

As shown in fig. 2-3 and 6, the vertical positioning assembly is a vertical positioning block 1 sleeved on each foundation bolt 10, connecting blind holes 101 are formed in the side walls of the vertical positioning blocks 1, which are connected with each other, and first positioning steel bars 41 penetrate through the symmetrical connecting blind holes. Wherein, the threaded reinforcement structure of rag bolt 10, set up on the vertical locating piece 1 and establish the screw thread perforation 102 of being connected with the vertical portion screw thread cover of rag bolt 10, every vertical locating piece 1 meets with horizontal part 10b after being connected with vertical portion 20, realize the location of every vertical locating piece 1 and rag bolt 10, guarantee simultaneously that the connection blind hole 101 level of adjacent vertical locating piece 1 lateral wall is relative, make first locating reinforcement 41 can wear to establish in the vertical locating piece 1 of symmetry and realize connecting, connect the whole square fastening structure that constitutes after the shaping (as shown in fig. 6).

Specifically, as shown in fig. 4 and 6, the positioning device further includes horizontal positioning blocks 2 connecting the horizontal portions 10b of the anchor bolts 10, and second positioning bars 42 are connected and fixed between the horizontal positioning blocks 2. Preferably, the horizontal positioning block 2 is provided with a clamping groove 201 penetrating through the horizontal portion, and the horizontal portions of the symmetrical foundation bolts 10 are positioned and penetrated in the clamping groove 201 to realize connection. In this connection state, the relative rotation between the anchor bolts 10 with respect to the vertical positioning block 1 is inevitable, which causes the problem that the heights of the four anchor bolts 10 are not equal, thereby achieving the connection strength with the prefabricated part while keeping the heights of the tops of the four anchor bolts 10 equal.

As shown in fig. 5-6, the positioning device further includes leveling positioning blocks 3 fixed to the top of the vertical portion 10a at a vertical distance from the vertical positioning block 1, and third positioning steel bars 43 are connected and fixed between the symmetrical leveling positioning blocks 3.
