technical field

The utility model belongs to the construction field and relates to a assembling device, in particular to a tool-type assembling device for combining steel templates in building construction.

Background technique

In the construction of construction projects, when the combined steel formwork is used in the wall structure, large cross-section column and other structures, it is necessary to fasten the tie bolts and the outer steel corrugation of the formwork. The spacing of the tension bolts has a direct impact on the overall rigidity of the formwork. Concrete members with different cross-sections and different heights have different spacing between the tension bolts of the formwork, and the formwork often has multiple openings and repeated repairs, resulting in uneven surface of the formwork. , affecting the quality and appearance of concrete members. In addition, compared with bamboo (wood) plywood formwork, the on-site assembly of combined steel formwork is relatively low in work efficiency, and there are more joints in the formwork, so the application of combined steel formwork is relatively less in recent years.

Utility model content

The utility model provides a tool-type assembling device for a combined steel formwork in order to overcome the problems of multiple openings and many joints in the formwork during use of the combined steel formwork.

The utility model adopts the following technical scheme: a combined steel formwork tool-type assembling device, including a concrete wall, and multiple sets of combined steel formworks corresponding to each other are laid on both sides of the concrete wall, and there are sets between adjacent combined steel formworks. Assembled channel steel, combined steel formwork and assembled channel steel are on the same plane, U-shaped card holes are distributed on the flange plates on both sides of the assembled channel steel, and U-shaped cards are inserted into the U-shaped card holes to connect the flange plate with it. The side ribs of the bonded combined steel formwork are fixedly connected, and the web plate of the combined channel steel is distributed with tension bolt holes, and the tension bolts penetrate into the corresponding tension bolt holes on the combined channel steel on both sides of the concrete wall In the above, the outer side of the combined steel formwork and assembled channel steel is reinforced by steel pipe transverse corrugations, and the two ends of the pull bolts pass through the corresponding steel pipe transverse corrugations respectively and are then fixed with fixing pieces.

Preferably, the fixing part includes a 3-shaped fastener and a nut, and the 3-shaped fastener is set on the end of the pull bolt to clamp the steel pipe transverse steel corrugation, and then fixed by the nut.

Preferably, one end of the assembled channel steel is fixedly connected with a U-shaped round steel lifting ring.

The beneficial effects of the utility model are: when constructing structures such as concrete shear walls, retaining walls, and large cross-section columns, the device can be used for construction by loose assembly, and the device can be combined with wide-surface combined steel formwork After forming a large formwork and hoisting it to the construction site with a crane, the steel corrugations and formwork on both sides are fastened by the pull bolts and 3-shaped fasteners to complete the formwork reinforcement. After adopting this device, there is no need to open half-bolt holes on the combined steel formwork, which avoids the problem of multiple openings and repeated repairs on the formwork, which will cause the formwork surface to be uneven and affect the quality of concrete components; at the same time, due to the high rigidity of the channel steel , and the channel steel is integrated with the formwork, which can improve the overall rigidity of the formwork; the method of ground assembly and crane hoisting not only improves the work efficiency, but also reduces the joints of the formwork, which can ensure the flatness and visual quality of the wall and column structure; The device assembly is flexible, versatile, reusable, long service life, low construction amortization, wide application range, in line with the national policy of "substituting steel for wood".
