Description

A kind of unwrapping wire punch die

Technical field

The utility model relates to a kind of unwrapping wire punch die, belongs to building operations auxiliary construction technical field of tools.

Background technology

Along with the development of builing industry, more and more higher to the required precision of concrete floor measurement unwrapping wire, therefore, to the quality requirement of unwrapping wire hole forming also corresponding raising.In conventional art, normal employing is built wooden model temporarily and is made unwrapping wire hole, wooden model easily loses shape in work progress on the one hand, distortion, the unwrapping wire hole poor effect of moulding, and wooden model number of turnover in construction is limited, process loaded down with trivial details, peace is torn inconvenience open, be unfavorable for recycling, on the other hand, unwrapping wire hole all needs to carry out shutoff after finishing using, because the unwrapping wire hole size of wooden model moulding differs, later stage is not suitable for making unified plugging block and comes shutoff unwrapping wire hole, carry out concreting and carry out shutoff but need to again build at unwrapping wire hole place template, not only wasting manpower and material resources, and make claim for eot.

Summary of the invention

The purpose of this utility model is, a kind of simple in structure, easy construction is provided, and can realize unwrapping wire hole standardized construction, and the unwrapping wire punch die that the later stage also can this this unwrapping wire hole of Mold Making plugging block quick blocking, to overcome prior art deficiency.

The technical solution of the utility model: a kind of unwrapping wire punch die is the step cylindrical structure of the Plate Welding thick by 4～6mm;

Described step cylindrical structure is between the little cylinder of upper end large cylinder and lower end, to weld a doughnut-shaped steel plate to form, wherein large cylinder diameter 300mm, high 150～200mm, little drum diameter 200mm, high 50mm, doughnut-shaped steel plate internal diameter 200mm, external diameter 300mm.

Owing to having adopted such scheme, the utility model adopts unwrapping wire punch die on concrete floor, to make good forming effect, and the consistent unwrapping wire hole of size dimension, accurately makes thereby realize unwrapping wire hole, meets and measures requirement.After finishing using in this unwrapping wire hole, can adopt the unified plugging block of making of this mould to carry out quick blocking, reach the requirement of standardized construction.So compared with prior art, the utility model not only has advantages of simple in structure, easy construction to the utility model, all facilitate, use time saving and energy saving but also there are mounting or dismounting, and can increase work efficiency, speed up the work, save the advantages such as material.

Detailed description of the invention

In order to make the utility model object, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1, a kind of unwrapping wire punch die of the present utility model is the step cylindrical structure of the Plate Welding thick by 4～6mm, described step cylindrical structure is between the little cylinder of upper end large cylinder and lower end, to weld a doughnut-shaped steel plate to form, wherein large cylinder diameter 300mm, height, 200mm, little drum diameter 200mm, high 50mm, doughnut-shaped steel plate internal diameter 200mm, external diameter 300mm.

The utility model operating principle: the utility model can be implemented in the construction technology of existing employing template concreting floor, comprises the following steps:

Step 1, on the floor of mounted template, by design drawing, the position in unwrapping wire hole 3 is positioned to measurement, determine behind the position in unwrapping wire hole 3, carry out mark at this place;

Step 2, employing nylon film are by peripheral unwrapping wire punch die 2 parcel, so that then the later stage demoulding is fixed on mark by unwrapping wire punch die 2;

Step 3, after floor bar colligation completes, referring to Fig. 1, by designing requirement concreting floor 1, while building, notice that concrete does not drop 2 li of unwrapping wire punch dies;

Step 4, after concrete floor 1 sclerosis, unwrapping wire punch die 2 is removed, as shown in Figure 2, unwrapping wire hole 3 just completes;

Step 5, the unwrapping wire punch die 2 of dismounting is placed on clean and level and smooth ground, and at the interior parcel nylon film of unwrapping wire punch die 2, the cross reinforcing bar 5 having bundled is placed on to unwrapping wire punch die 2, in order to strengthen the intensity of plugging block 4; Then toward building in unwrapping wire punch die 2 and the concrete of concrete floor 1 same levels, while building, ensure that the height of plugging block 4 upper surfaces, lower than concrete floor 1 height 10mm, after concrete setting, takes out the concrete block of moulding, referring to Fig. 3 and Fig. 4, just form plugging block 4;

Step 6, after finishing using in unwrapping wire hole 3, will in unwrapping wire hole 3, clean out, and water is moistening, then unwrapping wire hole 3 peripheries adopt high-grade cement mortars smear evenly, referring to Fig. 5, by the plugging block of making in advance 4 by 3 shutoff of unwrapping wire hole;

Step 7, last, employing high grade mortar is by floating plugging block 4 upper surfaces to concrete floor 1, and its soffit adopts powder of lacquer putty for use on to strike off, and completes 3 shutoff of unwrapping wire hole.
