Adjustable metal opposite-pull piece and shaping combined formwork

Abstract

The invention relates to an adjustable metal opposite-pull piece. The adjustable metal opposite-pull piece comprises a first pull piece body, a first adjusting screw rod, a bidirectional double-hole internal thread sleeve, a second adjusting screw rod and a second pull piece body. A first connecting hole is formed in one side of the first pull piece body, and the first adjusting screw rod is fixedly connected with the other side of the first pull piece body; a second connecting hole is formed in one side of the second pull piece body, and the second adjusting screw rod is fixedly connected with the other side of the second pull piece body; and the bidirectional double-hole internal thread sleeve is provided with two parallel internal thread holes, the first adjusting screw rod is connectedinto one internal thread hole from one side of the bidirectional double-hole internal thread sleeve, and the second adjusting screw rod is connected into the other internal thread hole from the otheropposite side.

Description

technical field [0001] The invention relates to the technical field of building templates, in particular to an adjustable metal pair pull piece and a shaped composite template. Background technique [0002] Formwork engineering in the field of building structure construction is an important part of reinforced concrete structure engineering and an effective construction method to ensure the construction quality and safety of building structures. The stereotyped composite formwork is a formwork system composed of various specifications of standard shaped steel formwork, connectors and delivery parts. It is suitable for cast-in-place concrete frames and cast-in-place concrete columns, beams, slabs, and shear walls in industrial and civil buildings. Such as formwork engineering is a formwork type and system widely used in the industry. In the process of wall formwork construction, in order to make the inner and outer wall panels firmly connected, wall-through screws are usually...

Problems solved by technology

[0003] The inventor found in the research that the pull tabs currently used are made of two metal pull tabs welded with round steel in the middle. Manual welding process, if the thickness of the wall on site is inconsistent, the processed finished product cannot be used, and it needs to be reprocessed, which will cause waste and affect the construction progress. Fix it with U-shaped clips. Due to the thickness of the metal pull sheet of about 3mm, when the flat steel formwork is sandwiched by the pull sheet, there will be gaps. When the concrete is poured, it is easy to leak grout, which will affect the construction quality; The height of the plane steel formwork is constantly rising, and there is a height difference between the corner formwork installed at the corner of the formwork structure and the plane formwork. The size of the formwork structure affects the construction progress
