Description

Telescopic corner C groove

Technical Field

The invention relates to the field of building construction, in particular to a concrete pouring mold.

Background

In order to facilitate concrete forming, in the building field, a plurality of templates and various connecting pieces are generally built into a template before concrete is poured, two templates are parallel during building, a gap exists between the two templates, the gap is a pouring cavity, and concrete is poured into the pouring cavity during pouring. And after the concrete is solidified, the formwork can be removed, and the solidified concrete forms the wall body of the building.

Each room of the building is provided with four vertical walls, so when the templates are built, the four templates are firstly adopted to build a frame in a shape of a Chinese character hui, and two adjacent templates in the four templates are mutually vertical. In order to improve the strength of the templates, the two adjacent templates need to be fixed by the corner C groove, and when the two adjacent templates are fixed, the two ends of the corner C groove are respectively fixed with the two templates.

In order to facilitate machining, the corner C groove of the fixed template is machined in a centralized mode at a special manufacturing position, and then the machined component is transported to a construction site to be built according to a drawing. However, when a new building is built, the sizes of the required formworks are different due to different house types of the new building, the length of the original corner C-shaped groove is not suitable for the new formwork, the fixing effect on the new formwork is not good, and therefore the corner C-shaped groove generally needs to be manufactured again at present. However, the time and energy consumption for remanufacturing the corner C groove are long, and the construction period is easily delayed.

Disclosure of Invention

The invention aims to provide a corner C-shaped groove with adjustable size.

In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a telescopic corner C groove, includes sliding connection's first connecting block and second connecting block, all is fixed with first arm and second arm that can fix with double-phase adjacent template respectively on first connecting block and the second connecting block, the contained angle between first arm and the second arm is less than 180.

The scheme has the following beneficial effects:

there is the contained angle between first arm in this scheme and the second arm, during the fixed die plate, first arm and second arm are fixed with two adjacent templates of mutually perpendicular respectively. When templates with different sizes need to be connected, the second connecting block slides relative to the second connecting block, and the height of the corner C groove formed by the first connecting block and the second connecting block is reduced and changed. The length of the corner C groove can be adjusted, templates with different heights can be fixed, and the problem that the construction period is delayed due to the fact that the corner C groove is produced again is avoided.

Preferably, as a further improvement to the basic solution, an included angle between the first arm and the second arm is a right angle. When the template is installed, the adjacent templates are vertical, and the first arm and the second arm in the scheme can be better attached to the adjacent templates, so that gaps cannot occur between the first arm or the second arm and the templates, and the first arm and the second arm are prevented from deforming when being subjected to lateral force.

Preferably, scheme two, as the further improvement to basic scheme, be fixed with the guide block on the second connecting block, be equipped with the gliding guide way of confession guide block on the first connecting block along vertical direction. The second connecting block is for first connecting block slip in-process, and the guide way plays the guide effect to the slip of guide block, effectively avoids the second connecting block crooked.

In a third preferred embodiment, as a further improvement of the second preferred embodiment, the cross sections of the guide block and the guide groove in the horizontal direction are both dovetail-shaped. The guide block can not drop from the guide way along the guide way slip in-process, further avoids the second connecting block crooked.

Preferably, as a further improvement to the basic solution, the side wall of the first connecting block, which is far away from the first arm and the second arm, is in arc transition with the adjacent side wall. No edge is arranged between the side wall of the first connecting block, which is far away from the first arm and the second arm, and the other side walls, so that the edge can be prevented from scratching workers.

Preferably, as a further improvement to the basic solution, the first preferred solution, the third preferred solution or the fourth preferred solution, a rubber sheet is fixed on the second connecting block. When the second connecting block slides, the hand of the worker contacts with the rubber sheet, under the condition that the pressure of the hand of the worker on the second connecting block is the same, the friction force between the hand of the worker and the rubber sheet is larger, the hand of the worker cannot slip, and the second connecting block is prevented from falling and injuring the worker by a crashing object.
