Abstract

The invention discloses a small-size deformation joint construction adjustable formwork system which is characterized in that forward thread sections and reverse thread sections are arranged on screwsat intervals in the axial direction, connecting sleeves are fixed to the vertically adjacent screws, and handles are arranged at the tops of the screws at the top ends. The nuts are respectively arranged on the forward thread section and the reverse thread section of the same screw and internally provided with corresponding threaded holes, the steel formworks are parallelly arranged on two sidesof the screw respectively, the lug plates are fixed on the steel formworks at intervals along the axial direction of the screw, and the nuts are hinged with one ends of the two pull plates on two sides corresponding to the steel formworks respectively. The other ends of the two pull plates hinged with the screw on the adjacent forward-rotating or reverse-rotating thread section of the screw rod are respectively hinged with the lug plates. The forward and reverse thread sections are arranged on the screw rods, so that the nuts, the lug plates and the pull plates form an openable shear type structure, the distance between the steel formworks can be conveniently adjusted, the problem that the formworks are difficult to mount and dismount in small-size deformation joint construction is solved,and the device has the advantages of being convenient to mount and dismount, flexible in adjustment, high in supporting strength and capable of being repeatedly used.

Description

technical field

[0001] The invention belongs to the technical field of construction machinery, and in particular relates to an adjustable formwork system for construction of small-sized deformation joints which is convenient for disassembly and assembly, flexible in adjustment, high in support strength and reusable. Background technique

[0002] In industrial and civil buildings, due to the influence of factors such as temperature changes, uneven foundation settlement and earthquakes, additional stress and deformation will be generated inside the building structure, especially small high-rise and high-rise buildings will amplify these additional stress and deformation, such as Improper handling can cause cracks or even collapse of the building structure. For this reason, it is necessary to disconnect the structure in the sensitive parts that may be deformed in advance to form deformation joints, so as to ensure that each part of the building structure has sufficient deformat...
