Embodiment Construction

[0069] Such as Figure 7 Shown is a method for making a prefabricated component, the method comprising the following steps:

[0070] Step 1, welding of steel skeleton:

[0071] Welded steel bar skeleton 11; wherein, steel bar skeleton 11 comprises upper row of steel bars and lower row of steel bars, and stirrups 11-3 welded along the length direction of said upper row of steel bars and said lower row of steel bars, and said upper row of steel bars includes multiple The upper reinforcement bar 11-1, the lower row of reinforcement bars includes a plurality of lower reinforcement bars 11-2;

[0072] Step 2. Formwork support and installation of positioning fixtures:

[0073] Formwork is supported on the outside of the reinforcement frame 11, and a plurality of positioning fixtures are installed on the top of the formwork;

[0074] Step 3. Adjustment of steel skeleton:

[0075] The method of adjusting the distance between the reinforcement frame 11 and the bottom of the formwor...

Abstract

The invention discloses a method for making a prefabricated component, which comprises the following steps: 1. Welding the steel frame; 2. Installing the formwork support and positioning fixture; 3. Adjusting the steel frame; 4. Pouring concrete and removing the positioning fixture , to obtain concrete prefabricated components. The method of the invention has simple steps, convenient construction, and easy operation by workers. By supporting the formwork on the outside of the reinforcement frame and installing a plurality of positioning fixtures on the top of the formwork, the distance between the reinforcement frame and the bottom of the formwork is adjusted by the positioning fixtures to meet the requirements of the concrete protection layer. fixed value, and then realize the positioning of the bottom of the steel skeleton, and facilitate the formation of a steel protection layer at the bottom of the steel skeleton. On the one hand, it saves the support and binding of multiple concrete pads, and on the other hand, it reduces the consumption of concrete pad materials. Thereby increasing the overall strength of the concrete precast member.

Description

technical field [0001] The invention belongs to the technical field of prefabricated component manufacturing methods, and in particular relates to a prefabricated component manufacturing method. Background technique [0002] At present, in the process of prefabricated component construction, the steel skeleton is generally bound first, and a concrete pad is placed at the bottom of the steel skeleton. The concrete pad is tied to the bottom of the steel skeleton by tying wires, so that the reinforced skeleton is poured with concrete to form a reinforced skeleton. The bottom of the steel reinforcement layer is formed; [0003] However, in the current construction process of prefabricated components, it is difficult to fix the concrete pads firmly with the bottom of the steel skeleton by tying wires, and the steel skeleton is easily displaced during the concrete pouring and vibration process, which makes it difficult to control the thickness of the steel protective layer, which ...
