Embodiment Construction

[0016] Example figure 1 and figure 2 As shown, the positioning method of the pre-embedded steel bar of the assembled sleeve of the building component of the present invention comprises the following steps:

[0017] Step 1. Make the steel bar positioning tool. The positioning tool includes a steel plate 1 and a sleeve 4. Set a matching through hole 2 on the steel plate 1 according to the spacing and plane position of the embedded steel bar. The sleeve 4 and the through hole 2 are coaxially welded on the On the steel plate 1, a vibrating port 3 for concrete pouring is arranged between the adjacent through holes 2 of the steel plate 1;

[0018] Step 2. Preliminary positioning of the pre-embedded steel bars bound on the cast-in-place structure, and determining the plane positioning dimensions of the pre-embedded steel bars;

[0019] Step 3, according to the position of the pre-embedded steel bar, insert the sleeve 4 of the completed positioning tool into the pre-embedded steel ...

Abstract

The invention discloses a positioning method for pre-embedded steel bars in assembled sleeves of a building element. According to the method, firstly a steel bar positioning tool is made, a steel plate is provided with through holes matched with the pre-embedded steel bars and vibrating holes, and the sleeves are welded on the through holes respectively; preliminary positioning is performed on thepre-embedded steel bars to determine the planar positioning dimensions of the pre-embedded steel bars; the sleeves are enabled to sleeve the pre-embedded steel bars, and the steel plate is fixed; concrete pouring is carried out on the cast-in-situ structure, the position and perpendicularity of the pre-embedded steel bars are re-checked after the pouring and before the initial setting of the concrete so as to complete the positioning for the pre-embedded steel bars. The positioning method realizes accurate positioning for the pre-embedded steel bars through the self-made tool, ensures the element to be hoisted in place for one time, and improves the construction efficiency and the installation quality of the element.

Description

technical field [0001] The invention relates to a positioning method for pre-embedded steel bars in an assembled sleeve of a building component. Background technique [0002] Usually pre-embedded sleeves are embedded in the prefabricated components of prefabricated residential buildings, and at the same time the steel bars are embedded in the cast-in-place structure. During the hoisting process, the embedded steel bars need to be aligned with the embedded sleeves. After the components are fixed, the embedded sleeves are completed later. grouting. Prefabricated residential prefabricated component sleeve reserved reinforcement is a very important process and the basis of the entire assembly. The accuracy of pre-embedded steel bars directly determines the efficiency of component hoisting. At the same time, the subsequent pre-embedded sleeve grouting connection technology is the core technology of prefabricated component installation. Therefore, the accuracy of the positioning ...
