The conversion structure is arranged on the template A and is connected with the template A through a connecting bolt, and a diaphragm plate is poured between the conversion structure and the template B. And compared with a non-conversion structure, the diaphragm plate section which cannot be demolded is changed into a conversion structure with a smaller structure, so that the efficiency is higher, and more manpower is saved. In addition, the angle of the conversion structure can be customized, and the conversion structure can be used for various oblique cross diaphragm plate demolding scenes and is high in applicability and practicability.

Description

Technical Field

[0001] The utility model relates to a wall formwork, in particular to a formwork structure for integrated demoulding of an outer formwork of an oblique partition wall of a road or bridge body. Background Art

[0002] In order to solve the problem of demoulding the outer formwork at the diaphragm of the oblique beam in the road and bridge, the traditional formwork uses manual lifting and demoulding of the outer formwork of the diaphragm separately. In actual use, there are problems such as low construction efficiency, high safety risks, inconvenient operation, and difficult to ensure quality. The prefabricated production line formwork cannot achieve the overall demoulding of the diaphragm formwork due to the demoulding interference of the "sharp angle" edge of the diaphragm. Like the traditional formwork, the formwork here has to be lifted and demoulded separately, which greatly affects its construction efficiency and cycle.

[0003] When the beam diaphragm is oblique, the demoulding direction of the production line template remains unchanged, and the demoulding angle on one side of the diaphragm is an obtuse angle, so the template and the beam will not interfere; but the diaphragm on the other side is an acute angle (the beam is given by the design institute, the diaphragm outline cannot be changed, and the template is designed according to the beam outline). Therefore, when the template is demoulded, the template at the acute angle interferes with the beam and the demoulding action cannot be completed. Since the template at the acute angle cannot be demoulded normally, when designing the template, the template at the diaphragm can only be segmented separately, and the template at the diaphragm without the diaphragm is demoulded by the oil cylinder, and then the template at the diaphragm is removed separately by manual labor. The efficiency is low and the labor intensity of the workers is high. Utility Model Content

[0004] The utility model aims to solve the problems of low efficiency and high labor intensity of workers in manually removing the templates at the diaphragm, and proposes a template structure for integrated demoulding of the outer template of the oblique partition wall of a road and bridge body.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A formwork structure for integrated demoulding of the outer formwork of the oblique partition wall of a road or bridge body, characterized in that it includes a conversion structure, a formwork A, and a formwork B. The conversion structure is arranged on the formwork A and connected to the formwork A by connecting bolts, and the diaphragm is cast between the conversion structure and the formwork B.

[0007] Preferably, the template A is arranged on one side of the acute angle surface of the partition, and the template B is arranged on one side of the obtuse angle surface of the transverse partition.

[0008] Preferably, the conversion structure comprises a conversion template, a connecting plate, and reinforcing ribs, the conversion template is integrally connected to the connecting plate, and the connecting plate is integrally connected to the reinforcing ribs.

[0009] Preferably, the conversion structure has three side surfaces, one side is connected to the formwork A, one side is parallel to the beam body, and one side is parallel to the transverse partition.

[0010] Preferably, the conversion template is arranged on the surface of the conversion structure contacting the beam body and the transverse partition, and the connecting plate is provided with holes for installing connecting bolts.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] Compared with the non-conversion structure, the diaphragm section that cannot be demoulded is converted into a smaller conversion structure, so it is more efficient and saves more manpower. In addition, the angle of the conversion structure can be customized and can be used in various oblique diaphragm demoulding scenarios, with high applicability and strong practicality.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] like Figure 1 , 2 As shown, a formwork structure for integrated demoulding of the outer formwork of the oblique partition wall of a road and bridge body comprises a conversion structure 1, a formwork A2, and a formwork B3. The conversion structure 1 is arranged on the formwork A2 and connected to the formwork A2 by connecting bolts 4. The diaphragm to be demoulded is located between the formwork A2 and the formwork B3. The formwork A2 is arranged on one side of the acute angle surface of the diaphragm, and the formwork B3 is arranged on one side of the obtuse angle surface of the diaphragm. The cross section of the conversion structure 1 is a triangle. The diagonal of one side of the conversion structure 1 connected to the formwork A2 is the same acute angle as the acute angle of the diaphragm. The plane where one side of the acute angle is located is parallel to and fits with the acute angle surface of the diaphragm, and the plane is aligned with the formwork B3, and the diaphragm is cast on it.

[0018] The acute angle of the diaphragm can be converted into an obtuse angle by the conversion structure 1, thereby realizing the integrated demoulding of the template. When demoulding, first remove the connecting bolts 4 between the template A2 and the conversion structure 1, and then demould the template separately (because flange nuts are embedded in the beam body, and the conversion structure 1 is connected to the beam body by bolts). After the demoulding is completed, the conversion structure 1 is removed separately.

[0019] The conversion structure 1 includes a conversion template 11, a connecting plate 12, and a reinforcing rib 13. The conversion template 11 is arranged on the surface of the conversion structure 1 that contacts the cross partition and the beam body. The connecting plate 12 is arranged on the side where the conversion structure 1 is connected to the template A2 and is integrally connected to the conversion template 11. Holes for installing connecting bolts 4 are arranged on the connecting plate. The reinforcing rib 13 is arranged inside the conversion structure 1 and is integrally connected to the conversion template 11, so as to improve the strength of the conversion structure 1.

[0020] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
