Embodiment 1

[0033] This embodiment provides a bracket that can support the wall formwork on one side, including the vertical main back flute 1, the ground beam 2, the diagonal brace 3 and the anchor bolt 4; the vertical main back flute 1, the ground beam 2 and the The diagonal braces 3 are connected in turn to form a right-angled triangle bracket. One end of the ground beam 2 is connected to one end of the vertical main back 1, and the axes of the two are perpendicular; one end of the diagonal brace 3 is connected to the other end of the ground beam 2, and the other end of the diagonal brace 3 One end is connected with the vertical bar section of the vertical main back flute 1. The ground beam 2 is used as a right-angled side for contact with the ground; the vertical main back flute 1 is used as another right-angled side for contact with the wall shaping formwork; the anchor bolts 4 pass through the ground beam 2 at the right angle of the triangular bracket Finally, it is used to be burie...

Embodiment 2

[0035] Further improvement on the basis of Example 1, the two optimized structures of the telescopic components are as follows:

[0036] The first type: the telescopic assembly adopts a hydraulic cylinder, an air cylinder or an electric push rod assembly, and this embodiment adopts a hydraulic cylinder. The fixed end of the telescopic assembly is hingedly connected to the ground beam 2 through a pin shaft, and the telescopic end of the telescopic assembly is hingedly connected to the vertical main back rib 1 through a pin shaft.

[0037] The second type: the telescopic assembly includes an adjustment cylinder 31, an adjustment screw I32 and an adjustment screw II33; the adjustment cylinder 31 is provided with an internal thread; The threaded connection extends into the adjustment cylinder 31; one end of the adjustment bolt II33 is hingedly connected with the vertical main back corrugated 1, and the other end is threaded into the adjustment cylinder 31 by the other end of the a...

Embodiment 3

[0041] Further improvement on the basis of embodiment 2 includes a plurality of right-angled triangular brackets, and the plurality of right-angled triangular brackets are sequentially arranged along the width extension direction of the wall shaped formwork. Adjacent right-angled triangles are connected by steel pipes, and the axial ends of each steel pipe are respectively fixedly connected to the vertical main back flute 1 on the corresponding side.

[0042] Also includes a pressure beam 7, the pressure beam 7 is extended and arranged along the arrangement direction of all right-angled triangular brackets, a number of through holes are opened on the pressure beam 7, and all the through holes are distributed sequentially along the axial extension direction of the pressure beam 7; through the outer connecting rod 8 is connected with the anchor bolt 4 after passing through the through hole, and is tightened and fixed by the lock nut; Contact with ground beam 2. The vertical mai...

Abstract

The invention discloses a support capable of supporting a wall formwork on a single side. The support comprises a vertical main back ridge, a ground beam, an inclined strut and a foundation bolt, thevertical main back ridge, the ground beam and the inclined strut are connected in sequence to form a right-triangle support body, the ground beam serves as a right-angle side and is used for making contact with the ground, the vertical main back ridge serves as the other right-angle side and is used for making contact with the wall shaping formwork, the foundation bolt penetrate through the right-angle position of the triangular support body and then is used for being embedded in the ground below the wall shaping formwork, the inclined strut adopts a telescopic assembly, the fixed end of the telescopic assembly is hinged to the ground beam, and the telescopic end of the telescopic assembly is hinged to the vertical main back ridge. According to the support, under the condition that the operation space is limited, when a wall is supported by the single-side support, the wall formwork can be supported without independently arranging a split screw and an embedded cone; and after wall concrete pouring is completed, cone hole plugging is not needed any more, and therefore the appearance quality of the concrete wall is greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a bracket capable of unilaterally supporting a wall formwork, especially for the construction of a nuclear power plant wall formwork support. Background technique [0002] During the construction of some factories and other buildings, the factories are all cast-in-place reinforced concrete structures. Due to the large amount of on-site engineering, the tight construction period, and the compact layout of the buildings, cross-construction between adjacent walls of each factory building is frequent. Due to the limitation of the construction site, it is impossible to place pull bolts to control the lateral pressure of the concrete during the construction of some walls, which brings great inconvenience to the formwork construction. In the case of limited operating space, it has always been difficult to standardize and standardize the formwork support on one side of the wall. Fo...
