Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an aluminum alloy formwork supporting structure for a steel bar truss floor deck. Background Art

[0002] Reinforced truss floor decks (hereafter referred to as truss decks) are composite load-bearing slabs made by connecting the steel trusses and the base plate through resistance spot welding. They feature mechanized production, uniform reinforcement spacing, consistent concrete cover thickness, and high-quality floor construction. Aluminum alloy formwork is a concrete formwork system designed according to a modular design and extruded using specialized equipment, allowing for flexible assembly to accommodate varying structural dimensions.

[0003] In the actual construction process, some building concrete structures use truss plates as the bottom formwork of concrete floor slabs, and aluminum alloy formwork as the bottom formwork and side formwork of concrete structure frame beams.

[0004] Traditional aluminum alloy formwork bases utilize 60-to-48 series steel pipes as an adjustable support structure system, while the truss plate base utilizes 48 series disc buckles (or steel pipe fasteners) + keels as a support system. However, the aluminum formwork + truss plate combined construction system has two support structures. Due to the different diameters of the steel pipes, the aluminum formwork beam bottom support and the truss plate bottom support cannot be connected as a whole, which does not meet the specification requirement for the formwork support system to be connected as a whole. Alternatively, using 60-to-48 butt-fastener steel pipes to connect the two support structures would waste a significant amount of labor. Therefore, the present invention proposes an aluminum alloy formwork support structure for steel truss floor decks to address the aforementioned issues. Utility Model Content

[0005] The purpose of the utility model is to provide an aluminum alloy formwork support structure for a steel bar truss floor deck, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the utility model provides the following technical solution: an aluminum alloy formwork support structure for a steel truss floor deck, comprising: a beam-side aluminum alloy formwork and a steel truss floor deck, wherein the beam-side aluminum alloy formwork is fixedly mounted at the lower end of the opening of the steel truss floor deck via a corner aluminum formwork, the beam-side aluminum alloy formwork is fixed via aluminum formwork tensioning screws, and the lower end of the beam-side aluminum alloy formwork is connected to an aluminum formwork early-removal plate;

[0007] The lower end of the steel truss floor deck is provided with a disc-type steel pipe support system, in which a threaded hollow steel pipe is installed. The upper end of the threaded hollow steel pipe is connected to a disc-type short pipe 1 through a rotatable sleeve, and the lower end is connected to a disc-type short pipe 2 through a rotatable sleeve.

[0008] Preferably, the disc-type steel pipe support system includes a disc-type horizontal rod, a disc-type diagonal rod, a disc-type vertical rod, a steel pipe and a disc-type adjustable support. The disc-type vertical rod is horizontally or vertically overlapped on the ground, the disc-type diagonal rod is obliquely fixed between the two disc-type vertical rods, and the disc-type horizontal rod is horizontally fixed between the two disc-type vertical rods.

[0009] Preferably, the adjustable support with buckle is inserted into the top end of the buckle upright, and the steel pipe is placed in the adjustable support with buckle 14 and contacts the bottom end of the steel truss floor deck.

[0010] Preferably, a buckle vertical rod is inserted into the lower end of the second buckle short tube.

[0011] Preferably, the lower end of the second disc buckle short tube is fixedly connected to a double-slot steel joist, and the left and right ends of the double-slot steel joist are fixedly mounted on the outer wall of the disc buckle upright.

[0012] Preferably, the rotatable sleeve is rotatably connected to the lower end of the first disc short tube and the upper end of the second disc short tube respectively.

[0013] Preferably, the upper and lower ends of the threaded hollow steel pipe are respectively inserted into the disc buckle short tube one and the disc buckle short tube two, and the outer wall and the inner wall of the rotatable sleeve are threadedly connected.

[0014] Preferably, a round tube is fixedly installed on the lower end of the aluminum mold early disassembly plate, and the round tube is inserted into the inner side of the upper end of the short tube of the buckle.

[0015] Preferably, ear plates are fixedly installed on the outer walls of the disc buckle short tube one and the disc buckle short tube two, and hand-tightened bolts are threadedly connected to the ear plates. An anti-sliding block is fixedly installed on one end of the hand-tightened bolt, and can contact the outer wall of the rotatable sleeve through the anti-sliding block.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By using a disc-type steel pipe support system, aluminum alloy beam formwork, steel truss floor deck, threaded hollow steel pipe, rotatable sleeve and other mechanisms, a continuous integral support structure of the aluminum alloy formwork for the steel truss floor deck is formed. That is, the aluminum alloy formwork support system for the concrete beam and the steel truss floor deck support system can be connected into a whole. This avoids the problem of inconsistent steel pipe diameters and difficulty in connecting into a whole between the traditional aluminum formwork 60 to 48 series steel pipe support system and other formwork support systems, effectively reducing safety risks. At the same time, in the beam and slab construction area where the aluminum formwork and steel truss floor deck are combined, the labor cost of aluminum formwork support and truss plate support can be saved, effectively accelerating the construction progress.

[0018] This support system can be adjusted in height through threaded hollow steel pipes, rotatable sleeves, and short tubes with buckles to meet the support requirements of different floor heights. BRIEF DESCRIPTION OF THE DRAWINGS
