Problems solved by technology

However, in the actual pre-embedding process, since the main reinforcement of the column is vertically arranged and has a long length, the main reinforcement of the column is very likely to be skewed outward as its length increases.
[0004] In the prior art, for the above situation, one way is to use steel bars to intercept the outside of the main reinforcement of the column. This method can only avoid the tendency of the main reinforcement of the column to tilt outwards, but cannot limit the verticality of the main reinforcement of the column; Another way is to use gas cutting to cut holes on the steel plate, and use the cut holes as the limit holes for positioning the main reinforcement of the column. In this method, gas cutting is used to cut holes, and the accuracy of the cut holes cannot be guaranteed, and you cannot align the columns once. The verticality of the main reinforcement is limited
Therefore, no matter which way, there are defects that the position of the main reinforcement of the column cannot meet the design requirements and the positioning accuracy is low

Embodiment 1

[0033]Example 1: A positioning frame used for pre-embedded column main reinforcement, refer tofigure 1 , Including a tire frame body 1 arranged horizontally, and the tire frame body 1 is in the shape of a "mouth". The carcass body 1 includes a bottom mold 11 in the shape of a “mouth” and a positioning cover 12 matched with the bottom mold 11. A positioning sleeve 2 is pierced on the bottom mold 11, and the positioning sleeve 2 and the tire frame body 1 are both processed by CNC machine tools. The positioning sleeve 2 and the bottom mold 11 are connected as a whole by welding. A number of positioning sleeves 2 are evenly distributed along the four sides of the bottom mold 11, and their fixed positions correspond to the positions of the main ribs of the column. The positioning cover 12 has a positioning hole 121 corresponding to the positioning sleeve 2.

[0034]Referencefigure 1 , The four outer side walls of the bottom mold 11 are respectively provided with U-shaped grooves, and the op...

Embodiment 2

[0044]Example 2: A positioning frame for the main reinforcement of the pre-embedded column, refer tofigure 2 , Including a tire frame body 1 arranged horizontally, and the tire frame body 1 is in the shape of a "mouth". The tire frame body 1 includes a positioning frame 14, and adjustment holes 141 are respectively opened on the peripheral sides of the positioning frame 14 (refer toimage 3 ), the adjusting hole 141 is opened along the length direction of the side where it is located, and the adjusting hole 141 vertically penetrates the positioning frame 14.

[0045]Referencefigure 2 A positioning sleeve 2 is vertically inserted in the adjusting hole 141, and the axial direction of the positioning sleeve 2 and the length direction of the adjusting hole 141 are perpendicular to each other. The positioning sleeve 2 slides in the adjusting hole 141. A lower pressing block 22 is fixedly sleeved on the top of the positioning sleeve 2, and the lower pressing block 22 is attached to the upper ...

Abstract

The invention relates to the technical field of steel reinforcement cage stand column main reinforcement positioning, and discloses a positioning jig frame for pre-embedding a stand column main reinforcements. According to the key points of the technical scheme, the positioning jig frame comprises a jig frame body arranged horizontally, positioning sleeves corresponding to the stand column main reinforcement are arranged on the jig frame body in a penetrating mode, the jig frame body and the positioning sleeve are both manufactured through a numerical control lathe, and supporting assemblies used for fixing the jig frame body are arranged on the side walls of the jig frame body correspondingly. The positions of the stand column main reinforcements are limited through the positioning sleeves, so that the positioning precision of the stand column main reinforcements is improved.

Description

Technical field[0001]The invention relates to the technical field of positioning the main reinforcement of a steel cage column, in particular to a positioning frame used for the pre-embedded column main reinforcement.Background technique[0002]The pile cap refers to the reinforced concrete platform set on the top of the pile foundation to connect the top of each pile to bear and distribute the load transmitted by the pier. In the prior art, the production of caps generally adopts two methods, prefabricated and cast-in-place. The prefabricated cap has the advantage of having little impact on the construction environment and has gradually been widely used. However, for larger caps, It cannot be transported after prefabrication, so this type of cap is still cast-in-place. When the cast-in-place type is used to make the cap, the general process is to build the scaffolding work platform, make the cap steel cage, build the cap forming mold, pour concrete, and finally solidify for a period ...
