Therefore, a plurality of sizing box girder templates are forced to be eliminated due to reasons such as storage, transportation and the like under the condition that the service life is not reached. The existing box girder template has the following defects:
the structure weight is big: in the traditional template, the supporting structure accounts for the larger weight proportion of the total weight of the template, so that the whole structure has larger weight;
the production cost is high: the overall cost of formwork production is high due to the large amount of steel used for the support structure;
the utilization rate is low: the template is a shaped steel template, and is large in size and inconvenient to transport and store, so that the template is scrapped after construction at one construction site is finished;
the transportation cost is high: the sizing box girder template has large volume, so that the transportation vehicle is inconvenient to transport, the rated load cannot be reached, the transportation capacity is reduced, and the transportation cost is increased;
the application range is single: the fixed box girder template can not be used for other purposes only under the same construction condition because the shape of the box girder template can not be changed, or the template can not be used because of the size adjustment of the box girder.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a foldable case roof beam template, provide a case roof beam template that small, light in weight, preparation and cost of transportation are low, application range is wide.
For solving the above problems, the specific technical scheme of the utility model is as follows: the utility model provides a foldable case beam mold board, flange board die block both ends pass through beta structure with case roof beam side form and flange board side form respectively and are connected, the flange board die block, case roof beam side form and flange board side form lower extreme an organic whole are connected with foldable plate, foldable plate's folding position corresponds with the folding position of the same case roof beam side form of flange board die block and flange board side form, be connected with support member I on the foldable plate respectively, support member II and support member III pass through threaded sleeve and connect, the support member III other end can be dismantled and be connected with support member IV.
The foldable structure is hinged and connected between the two through a pin shaft, a hinge or a bolt and the like.
The foldable plate, the support rod piece I, the support rod piece II, the support rod piece III and the support rod piece IV are all made of rigid materials. The irregular box girder template can be unfolded or folded into the shape of the box girder outer mold through folding.
In the using state, the box girder side mold and the flange plate side mold are respectively folded towards different sides relative to the flange plate bottom mold, the support rod piece I and the support rod piece II are respectively rotated to be connected, the support rod piece III is connected with the support rod piece IV, and the support rod piece IV is used for supporting the box girder side mold. And in the storage or transportation state, the template rod is disconnected, and the template is flattened and is placed similar to a plane template.
The utility model discloses the beneficial effect who brings does: 1. The structure is simple, the steel consumption is small, and the installation and the disassembly are convenient; 2. the manufacturing cost is low, and the cost can be effectively reduced due to small steel consumption; 3. the invention is convenient for transportation and storage, and in a non-working state, the invention can be unfolded into a plane, has small floor area and regular shape and is convenient for storage; 4. the application range is wide, and the prefabricated box girder can be suitable for various types of box girder prefabrication construction by replacing template accessories such as flange plate bottom moulds, wall body side moulds and the like; 5. because the transportation and storage cost is lower, be convenient for have enough to meet the need the use, the utilization ratio is higher.
