Embodiment 1

[0027] Such as figure 1 As shown, a prefabricated component of a concrete component includes a panel frame 3, a fixed formwork 1 and a movable formwork 2, the fixed formwork 1 is fixed on the panel frame 3, the fixed formwork 1 and the movable formwork 2 are in a positive relationship, and the fixed formwork 1 There is a gap for clamping the template between the movable formwork 2, and also includes a pressure plate bolt threaded on the plate frame 3, the axis of the pressure plate bolt is located in the width direction of the gap, and the end of the pressure plate bolt is connected to the The outer contact of movable formwork 2 also includes spring 7 and anti-loosening bolt 4, and described anti-loosening bolt 4 is threadedly connected on the plate frame 3, and the axis of anti-loosening bolt 4 is parallel to the axis of hold-down bolt 6, and described spring 7 is arranged between the movable formwork 2 and the anti-loosening bolt 4. In the working state, the two ends of the ...

Embodiment 2

[0033] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, as an easy-to-implement concrete solution, the panel frame 3 is U-shaped, and the fixed formwork 1 and the movable formwork 2 are located on different sides of the open end of the panel frame 3 respectively. In the above structure, the anti-loosening bolt 4 and the compression bolt 6 can be screwed to one side of the plate frame 3 at the same time, so as to complete the compression of the spring 7 and the adjustment of the position of the movable formwork 2 .

[0034] Since the shrinkage of the concrete mortar is smaller than the width of the gap between the fixed formwork 1 and the movable formwork 2, in order to facilitate the anti-leakage grout effect, it is preferable to select a spring with a larger elastic coefficient, and the spring 7 is composed of a plurality of disc-shaped A spring set formed by stacking springs.

[0035] In order to prevent the movable template 2 fr...

Embodiment 3

[0037] The present embodiment further limits the present invention on the basis of embodiment 1, as figure 1 As shown, in order to prevent the movable formwork 2 from being too skewed under the elastic stress of the spring 7 and to facilitate the forming quality of the prefabricated component, the springs 7 are multiple, and the multiple springs 7 are annular and evenly spaced relative to the axis of the compression bolt 6. The cloth also includes an anti-loosening plate 5 that fits in a gap with the compression bolt 6, the anti-loosening plate 5 is arranged between the spring 7 and the anti-loosening bolt 4, and the anti-loosening plate 5 is used for the spring 7 and the anti-loosening bolt 4 Stress transmission between them, the anti-loosening bolt 4 is more than one, and different anti-loosening bolts 4 are arranged on different sides of the compression bolt 6 .

Abstract

The invention discloses a prefabricated component of concrete components, comprising a plate frame, a fixed template and a movable template. The fixed template is fixed on the plate frame, the fixed template and the movable template are in a positive relationship, and there is a function between the fixed template and the movable template. In the gap between the clamping formwork, it also includes pressure plate bolts threadedly connected to the plate frame. On the frame, and the axis of the anti-loosening bolt is parallel to the axis of the pressing bolt, the spring is arranged between the movable template and the anti-loosening bolt. In elastic compression state; also includes prefabricated table and sealing strip. The invention provides a complete set of devices for prefabricated concrete components, which can achieve the technical effect of reducing the amount of slurry leakage or avoiding slurry leakage during the curing process of the prefabricated components.

Description

technical field [0001] The invention relates to the field of concrete component prefabricated equipment, in particular to a concrete component prefabricated component. Background technique [0002] In order to make up for the phenomenon of premature cracks in concrete, before the component is used (loaded), the concrete is pre-stressed, that is, in the tensile area of ​​the concrete, the steel bar is stretched by artificial force, and the steel bar is used. Retraction force pre-stresses the concrete tension zone. This stored preloaded pressure, when the member bears the tensile force generated by the external load, first offsets the preloaded pressure in the concrete in the tension area, and then the concrete is stretched as the load increases, which limits the elongation of the concrete. Delay or not make cracks appear, this form of concrete is prestressed concrete. Because prestressed concrete has the advantages of good crack resistance, high rigidity, low self-weight, a...
