Description

Technical Field

[0001] The utility model patent belongs to the field of building construction technology, and in particular provides a concrete structure template positioning device. Background Art

[0002] At present, in construction, most concrete structure formworks are positioned by wooden planks or positioning cards. The disadvantage is that when pouring column concrete, it is easy to cause quality problems such as bottom displacement, resulting in problems such as excessive dimensional deviation of the concrete structure and bottom displacement. Utility Model Content

[0003] The utility model aims to provide a concrete structure formwork positioning device, which solves the quality problem of the concrete structure caused by bottom displacement due to inaccurate bottom formwork positioning.

[0004] The utility model comprises an angle steel, a positioning device 1, and a template 4; the angle steel is a 40mm angle steel with a length of 200mm, a 100mm long slit 3 is cut along the right angle of the angle steel, two sides along the 100mm slit are bent outwards by 90 degrees, and fixing holes 2 are drilled on the upper parts of the two sides, and the fixing holes 2 are long holes or two round holes on each side, forming a positioning device 1; cement nails are used to fix the positioning device 1 on the outside of the four corner positioning lines of the concrete structure template 4, and the four-side templates 4 of the concrete structure are installed on the outside of the positioning device 1. It is made in the following way:

[0005] Use 200mm long 40 angle steel to cut a 100mm long slit 3 along the right angle. Then bend the cut 100mm angle steel 90 degrees outward along the two sides of the angle steel, and drill fixing holes 2 on its upper part after bending. The fixing holes are long holes or two round holes on each side, which are processed into concrete positioning devices 1. Before installing the template, use cement nails to fix the positioning device 1 to the outside of the four corner positioning lines of the concrete structure template along the template positioning line. Install the four-side template 4 of the concrete structure on the outside of the template positioning device 1 to ensure that the template joints are tight and the template is reinforced.

[0006] The advantage of the utility model is that the installation accuracy of the concrete structure formwork can be effectively controlled by the device, thereby ensuring that the appearance size and position of the concrete structure meet the design and specification requirements; the device has low manufacturing cost and the characteristic of being recyclable, and also has the characteristic of being widely used, and can be used at the right angles at the bottom of cast-in-place square concrete components of any size.

[0011] The utility model comprises an angle steel, a positioning device 1, and a template 4; the angle steel is a 40mm angle steel with a length of 200mm, a 100mm long slit 3 is cut along the right angle of the angle steel, two sides along the 100mm slit are bent outwards by 90 degrees, and fixing holes 2 are drilled on the upper parts of the two sides, and the fixing holes 2 are long holes or two round holes on each side, forming a positioning device 1; cement nails are used to fix the positioning device 1 on the outside of the four corner positioning lines of the concrete structure template 4, and the four-side templates 4 of the concrete structure are installed on the outside of the positioning device 1. It is made in the following way:

[0012] 1. Cut a 100mm long slit 3 along the right angle of the 200mm long 40 angle steel, then bend the cut 100mm angle steel 90 degrees outward along the two sides of the angle steel, and drill a fixing hole 2 on its upper part after bending. The fixing holes are long holes or two round holes on each side, and are processed into a concrete structure template positioning device 1.

[0013] 2. 40 angle steels are processed in batches at the processing site, and transported to the site for installation after anti-corrosion and rust removal. Before the concrete structure formwork is installed, cement nails are used to fix the concrete structure formwork positioning device 1 at the four corners of the concrete structure formwork along the concrete structure formwork line, and then the formwork 4 is installed on the outside of the fixing part.

[0014] 3. After the concrete pouring is completed, the concrete structure formwork fixings are removed with a small crowbar after the formwork is removed.

[0015] The construction steps of this utility model are as follows

[0016] 1. Before installing the concrete structure formwork, fix the concrete structure formwork positioning device 1 along the formwork line along the installation hole 2 with cement nails to the outside of the positioning line of the four corners of the formwork.

[0017] 2. Install the four-side formwork 4 of the concrete structure on the outside of the formwork positioning device 1 to ensure that the formwork joints are tight.

[0018] 3. After the concrete structure is demolded, use a small crowbar to remove the fixings for rotational use.
