Description
Technical Field
The invention relates to the technical field of main structure construction, in particular to a BIM technology-based template internal and external corner slurry leakage prevention structure and a construction method thereof.
Background
In the current vigorous development of the building industry, the structure needs to be cast after formwork erecting in the construction process of the building. However, in the prior art, after the formwork is supported, because the formwork is repeatedly used for a long time, each side of the formwork is damaged by different forces after being demolded by crowbars (or other tools), and finally, slurry leakage is serious after concrete pouring, and if the slurry leakage is not cleaned in time, the pouring quality of concrete is affected, and concrete waste is caused.
In view of the above problems, the conventional processing methods include:
the first traditional scheme is as follows: and cutting the seriously damaged template again to achieve a better seam splicing effect and reduce the slurry leakage phenomenon. The problems are as follows: before building standard layer template configuration, can carry out the template design, satisfy the standard layer demand when reducing the consumptive material, the template is cutting the back for the first time promptly, if cut once more, must can lead to joining in marriage the mould and change, needs more leftover bits to supply, finally leads to the wholeness variation of piece, and the shaping effect after the structure is pour also can the variation.
The second traditional scheme is as follows: before the template is installed, the template is placed after the lower opening of the template is filled with slurry, so that the slurry leakage phenomenon is reduced. The problems are that: because the mortar belongs to the rapid hardening material, the construction of the template has a period after all, and the template has a certain weight, if the operation is improper, the whole template is pressed downwards, the template system is deformed, the molding quality of the poured structure is influenced, and the upper opening of the template cannot be processed.
The traditional scheme is three: after the template is erected, a worker is arranged to perform mortar plugging treatment on the lower opening of the template. The problems are as follows: firstly, certain requirements are required for the quality of small construction works, and secondly, the concrete pouring has impact force on the template, mortar filled in the later period cannot resist, and finally, a large amount of concrete slurry flows out.
In summary, the main problems of the common construction process during the installation of the formwork are summarized as follows:
1. before the construction of the standard layer template, the template can be optimally designed, the cutting loss of the template is reduced, and the template can be cut according to the standard on site after the template is designed. However, when the template is removed, a worker may remove the template by using a crowbar (or a special tool), which inevitably damages the four edges of the template, and if the template is cut again, the template module number may be changed.
2. Before the template installation, sit thick liquid processing to the template bottom, because the template damage degree is inconsistent, sit the thick liquid and can not solve the smooth problem of template completely to the template has the dead weight, can cause the deformation or the damage of sitting the thick liquid, influences final shaping effect, and can not solve the upper shed and leak the thick liquid problem.
3. After the template is installed, mortar is used for joint filling treatment on the lower side of the template, but in the concrete pouring process, the joint filling mortar can be easily extruded due to the impact force of the concrete, and the phenomenon of mortar leakage cannot be solved.

step four: installing a template keel to complete a template reinforcing system;
step five: grouting liquid is led in from the grouting holes in the first plugging piece and the second plugging piece, when the grouting liquid overflows from the grouting holes, grouting operation is finished, and the grouting liquid formed after the grouting liquid is solidified blocks the internal corner or the external corner of the template;
step six: correcting the verticality and the flatness of the template, checking and accepting, and then pouring concrete in the template;
step seven: and removing the template, the ejector rod, the first plugging piece and the second plugging piece after the concrete is formed, and removing the grouting body.
