Problems solved by technology

Since the formwork cannot be supported on the slope surface, the concrete has fluidity, and the concrete on the slope surface cannot be vibrated, and it is completely piled up manually. The molding size error is large, the compactness is poor, and the surface is severely honeycombed.

Embodiment 1

[0025] Example 1: In figure 1 middle( figure 1 There is no slope template 6, pre-embedded tie bars 1, oblique tension bolts on the slope surface 2, horizontal tension bolts 4, horizontal tie bars, rubber gaskets 3), pre-embedded tie bars 1, oblique 2 pull bolts, 3 rubber gaskets, 4 horizontal pull bolts, 5 horizontal tie bars, 6 slope formwork, 7 square timber (back corrugated slope formwork), 8 steel pipes (slope formwork keel), 9 concrete cushion , side formwork 10, square wood (side formwork back corrugated) 11, steel pipe (side formwork keel) 12.

[0026] see figure 2 , the closed formwork construction process of the independent foundation, the two ends of the horizontal tie bars 5 are welded with the horizontal pull bolts 4 passing through the side formwork 10, the inner side is covered with rubber gaskets 3, and the butterfly card and the steel pipe (side formwork keel) 12 are used. Connecting and fixing the square timber (back corrugated side formwork) 11, formwork ...

Embodiment 2

[0033] Embodiment 2: The closed formwork support structure of the independent foundation includes templates, square timber, steel pipes, steel bars, tension bolts and concrete cushion 9, etc. Such as figure 1 with figure 2 As shown, the inclined tie bars are pre-embedded in the concrete cushion 9 as the traction support ends of the left and right inclined panels. The formwork structure improves the overall performance of the independent foundation formwork system. In the independent foundation cushion layer, the tie bars 1 are pre-embedded and welded to the paired wires, and the paired wires tie the slope formwork 6 to resist the buoyancy of the concrete to the slope formwork 6, so that the independent foundation formwork system is firm and stable.

[0034]There are many groups of templates, which are four side templates and slope templates 6 respectively. Each side formwork is sealed and butted in turn, and fixed on the upper side of the concrete cushion 9.

[0035] The ...

Embodiment 3

[0040] Embodiment 3: On the basis of Embodiment 2, the sealed butt joint structure adopted includes vertical end seats 14 fixed on the upper side of the left and right side formwork 10-1 and inclined end seats 15 fixed on the lower side of the left and right slope formwork 6 . see image 3 As shown, the inner side of the vertical end seat 14 is upwardly provided with a support plate 16, the upper edge of the support plate 16 is arc-shaped, the inner middle part of the inclined end seat 15 is provided with a support groove 17, and the groove bottom of the support groove 17 is concave arc-shaped, The upper edge of the support plate 16 is matched and installed in the support groove 17 . Simultaneously, column 18 is fixed on the outside of described vertical end seat 14, and column 18 upper end horizontal thread is connected with horizontal screw rod, and the inner end of horizontal screw rod is fixed with horizontal slide block, and vertical screw rod is threaded on the horizonta...

Abstract

The invention discloses an independent foundation closed type formwork structure and process. The independent foundation closed type formwork structure comprises templates, square timber, steel pipes,rebars and split bolts. Inclined binding bars are pre-embedded in a concrete cushion. The upper sides of the left and right side face templates are each connected with one side face template throughseal butt joint structures. Meanwhile the diagonal split bolts are perpendicularly installed on all the slope templates. All the diagonal split bolts and the corresponding pre-embedded binding bars are fixed together. The independent concrete cushion serves as the foundation, the area formed by all the side face templates and the slope templates in a surrounded mode serves as a closed pouring area, and thus a closed type formwork supporting purpose can be achieved. The overall performance of an independent foundation template system is improved, the binding bars are pre-embedded in the independent foundation cushion and are welded to split wires, the split wires are connected with the slope templates to resist buoyancy of concrete to the slope templates, and thus the independent foundationtemplate system is firm and stable.

Description

technical field [0001] The invention belongs to the technical field of formwork support technology improvement in the building construction process, and in particular relates to an independent foundation formwork support structure and process. Background technique [0002] In conventional independent foundation construction, only the side formwork is supported, and the slope formwork cannot be supported. When pouring concrete, the concrete on the bottom surface is compacted by vibrating with a plug-in vibrating rod. Since the formwork cannot be supported on the slope surface, the concrete has fluidity, and the concrete on the slope surface cannot be vibrated, and it is completely piled up manually. The molding size error is large, the compactness is poor, and the surface is severely honeycombed. 。 Contents of the invention [0003] The present invention overcomes the defects in the prior art and provides an independent foundation formwork technology that can ensure the s...
