Example Embodiment

[0037] The self-locking adjustable square tube joist support frame of this embodiment is a beam bottom load-bearing support method adopted when a disc scaffold is used as the support frame of the beam formwork 1, and the galvanized square tube is used as the beam bottom to bear the force. The crossbeam unit 8, the end of the crossbeam unit 8 is provided with a self-locking clamp 15 to lock the crossbeam unit 8 and the disc buckle upright 5 to prevent displacement and overturning. The horizontal plane of the crossbeam unit 8 has vertical perforations 9 inserted into the casing 4.2 and fully welded, The first top brace 4.3 under the first tray 6 is inserted into the casing 4.2 as a beam bottom support; the stressed beam is divided into two at the middle position, and a connecting beam 3 with crescent sockets 17 at both ends is arranged inside the beam unit 8. The positioning spring pin 14 is provided to realize telescopic adjustment.

[0038] Such as Figure 1-8 As shown, this sel...

Abstract

The invention discloses a self-locking adjustable square tube joist supporting frame and a construction method thereof. The self-locking adjustable square tube joist supporting frame comprises two supporting frame units which are symmetrically arranged relative to the longitudinal axis of a beam form; in addition, the two supporting frame units are transversely and adjustably connected by a connecting cross beam; each supporting frame unit comprises a beam bottom bracket, a buttonhole loop vertical rod and a cross beam unit; a first U-shaped tray is arranged at the top of each beam bottom bracket; each first tray is in supported joint with a beam bottom longitudinal backridge at the bottom of the beam form; each buttonhole loop vertical rod is vertically adjustable; a second U-shaped trayis arranged at the top of each buttonhole loop vertical rod; each second tray is in supported joint with a plate bottom longitudinal backridge at the bottom of a plate form; a clamping groove is formed in the end part of one end of each cross beam unit and is clamped in the corresponding buttonhole loop vertical rod. According to the self-locking adjustable square tube joist supporting frame and the construction method thereof disclosed by the invention, the technical problems that a jacking cross beam cannot be stretched for adjusting and is poor in stability are solved, and the technical effects of saving steel, reducing dead weight of a frame body and improving the working efficiency are realized.

Description

technical field [0001] The invention relates to the field of building engineering construction, in particular to a self-locking adjustable square tube joist support frame and a construction method thereof. Background technique [0002] With the emergence of large-scale modern building systems with large spans, high-rises, and different shapes, ordinary fastener-type steel pipe scaffolding has clearly shown a decline in terms of bearing capacity, production efficiency, and safety and stability, and cannot fully meet the needs of the development of the construction industry. It is imperative to vigorously research, develop and promote the application of new scaffolding. At present, there are two types of new scaffolds used in the market: bowl buckle type and disc buckle type (the wheel buckle type is a derivative of the disc buckle support frame, and its performance is equivalent to that of the disc buckle. No longer). After research and analysis, the bowl buckle frame and th...
