Problems solved by technology

The conventional practice is that the concrete strength grade value reaches 100% to be demolished, and the entire building formwork and support system cannot be dismantled early, resulting in a long turnover period for building formwork and other materials, which not only increases the burden of material use, but also occupies higher construction costs, and The main ribs, secondary ribs and scaffolding of the support system are slow to erect and have low safety performance

Embodiment 1

[0041] Such as figure 1 As shown, a quick-connect and early-release jacking bracket for construction has a support plate 1, a support column 2, an early-release bracket 3 and an adjustment device. The support plate 1 is arranged on the support column 2 , and the support plate 1 and the support column 2 are connected together by a hinge structure 4 . Preferably, the supporting column 2 is a screw rod, and the adjusting device includes two adjusting nuts 5 .

[0042] Such as image 3 As shown, the upper end of the support column 2 is processed into a protruding head 41, the protruding head 41 is in the shape of a spherical surface, the central position of the protruding head 41 is provided with a through hole 411 along the axial direction, and the inner wall of the through hole 1 411 is provided with an internal thread. A boss 42 is connected to the lower side of the support plate 1, and the boss 42 is hollow cylindrical. An axial through hole (not shown) corresponding to the...

Embodiment 2

[0050] The difference between this embodiment and Embodiment 1 is that there is a limiter on the support surface 1, such as Figure 5 As shown, in this embodiment, support plates 7 are respectively provided at one set of opposite sides of the support surface 1 . The support nail 11 in the first embodiment is replaced by the support plate 7, the support force of the support plate 7 is stronger, which can prevent the breakage of the support nail 11 during construction and use, and is suitable for building construction systems that require higher bearing capacity .

[0051] The invention provides a quick-connect early-dismantling roof bracket for construction, which is convenient for loading and unloading, and is very suitable for an early-dismantling support system.

Abstract

The invention discloses a quick joint early-dismantling jack for construction. The quick joint early-dismantling jack is provided with a supporting plate, an early-dismantling support and a supporting column. The supporting column is sleeved with the early-dismantling support, the supporting plate is arranged on the supporting column, and the early-dismantling support is connected with a quick joint ring. A main rib and an early-dismantling jack body need to be erected in an early-dismantling supporting system. After the structure is adopted, in the mounting process, the supporting plate directly acts on the mounting face of a building formwork, a mounting groove is formed in the installing face of the building formwork, a plate-rod connecting part can penetrate into the mounting groove of the building formwork, the quick joint ring abuts against the plate-rod connecting part, and the building formwork and the early-dismantling jack body are connected together through interaction of the quick joint ring and the plate-rod connecting part. In the mounting process, the speed is high, locating is accurate, and good stability is achieved. In the demounting process, only the plate-rod connecting part needs to be pounded out, the plate-rod connecting part is separated from the quick joint ring, the building formwork and the early-dismantling jack body can be separated, and then the building formwork can be dismantled early conveniently. The quick joint early-dismantling jack for construction is convenient to assemble and disassemble and very suitable for the early-dismantling supporting system.

Description

technical field [0001] The invention relates to a jacking bracket used for building formwork engineering support in concrete structure construction, in particular to a quick-connecting and early-dismantling jacking bracket for construction. Background technique [0002] During the construction of prefabricated building components in construction projects, building formwork and support systems need to be erected. The building formwork forms the pouring space and pours the concrete. After the concrete strength meets the design requirements, the formwork and support system are removed. The conventional practice is that the concrete strength grade value reaches 100% to be demolished, and the entire building formwork and support system cannot be dismantled early, resulting in a long turnover period for building formwork and other materials, which not only increases the burden of material use, but also occupies higher construction costs, and The main ribs, secondary ribs and sca...
