Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Such as Figure 1 to Figure 3 As shown, a beam formwork suspension structure poured and rammed for unsupported steel concrete structure beams includes suspenders 2, steel bars 7, steel plates 8, 14# channel steel 3, wood squares 4, tension bolts 6, and nuts 5. There is a suspender 2 on both sides of the steel beam 1, the upper part of the suspender 2 is fixed on the upper wing of the steel beam 1, the lower part of the suspender 2 passes through the wooden square 4 at the bottom of the steel beam 1, and an additional 14# channel steel 3 with a distance of 1000mm, the bottom of the 14# channel steel 3 is fixedly connected to the suspender 2 with two nuts 5; fixed.

[0036] Such as figure 2 As shown, the upper part of the suspender 2 and the upper wing of the steel beam 1 are fixedly connected by two 25mm steel bars 7, a 10mm thick 100mm*100mm ...

Abstract

The invention relates to a steel reinforced concrete beam pouring and tamping support-free suspension molding plate structure and a construction method. Two sides of a steel beam of the structure arerespectively provided with a suspension rod, the upper portion of the suspension rod is fixed on an upper wing of the steel beam, the lower portion of the suspension rod is fixed on a channel steel purlin of a beam bottom mold, and the distance of the channel steel purlin along the beam is 1000mm; the bottom of channel steel is fixedly connected with the suspension rod by virtue of two nuts; and abeam molding plate is fixed on two side surfaces of the beam by using a split bolt along the height direction. The construction method comprises the following steps: (1) installing a section steel column; (2) installing a section steel beam; (3) arranging a beam molding plate system; (4) installing a beam molding plate support-free suspension system; and (5) pouring the steel reinforced concrete.By sufficiently utilizing the bearing capability of the section steel, the beam molding plate is suspended on the section steel beam, before the concrete is hardened, a section steel skeleton is usedas a bearing stress system, no support is arranged below the molding plate, the circulation material is saved, and the construction speed is increased. The steel reinforced concrete beam pouring andtamping support-free suspension molding plate structure is more apparent in advantage in the construction process of the large-sectional and high altitude section steel beam concrete.

Description

technical field [0001] The invention relates to a pouring and tamping method for a steel concrete structure beam, in particular to a construction method for a steel concrete structure beam without support for hanging formwork. Background technique [0002] With the development of high-rise and super high-rise buildings, the application of steel concrete structures is becoming more and more popular. In the construction of general steel-wrapped concrete structures, the conventional formwork bent frame support method is adopted, that is, the traditional outsourcing formwork and lower bent frame form are adopted. [0003] The difference between the steel reinforced concrete structure and the ordinary reinforced concrete structure is that there is a steel skeleton in the steel concrete structure, and the steel has a larger bearing capacity. According to estimates, the concentrated line load that general steel beams can bear can reach tens of tons per meter. However, the traditi...
