The general quality of the building template common problem: the displacement axis, deviation of elevation, structural deformation, joints lax, mold release agents used improperly, building the template is not clean, closed or vertical construction template vent, pouring holes, building templates support Optional improper. The following talk about the main axis of the spaces.
Axis displacement:
a strictly according to the ratio of 1/10 ~ 1/50 of the divisions, sub-turn-like into detail and indicate the number of the various parts of the axis position, geometry, profile shape, reserve holes embedded parts After compound is correct, seriously technical tests on the production team and operating workers, as the construction template production, the basis of the installation;
b, the axis of the building template placed on its organization hand technical composite acceptance, confirm the correct formwork;
c, the roots and top of walls, columns construction template must be located a reliable limit measures, such as embedded in the floor slab concrete short-reinforced fixed steel formwork in order to guarantee the accuracy of the bottom position;
d to pull level in the formwork, the vertical pass line and set the vertical verticality of the line of control to ensure that the level of architectural templates, accurate vertical position;
e, according to the characteristics of concrete structures, building templates specifically designed to ensure that the construction formwork and scaffold has sufficient strength, rigidity and stability;
f, pouring concrete, building template axis bracket, top brace, bolts carefully check, composite, identify problems in time;
g, concrete pouring, uniform material under the symmetrical placement height should be strictly controlled to the extent permitted in the construction specifications.
Building a template in how to ensure the quality of construction are charged to die? The following are quality assurance measures on the formwork.
(1) architectural template have sufficient stiffness and bearing capacity and stability. We selected the building template series is already a mature architectural template Engineering Series, to ensure the construction quality of finished products meet the quality standards of the existing reinforced concrete. Series of architectural templates use of individual parts of the project, be calculated by the technical staff design can be used.
(2) strict control of the building template processing quality, the improved construction template production quality than the current national norms, and hold people accountable for test construction template products, where quality standards of products is not allowed to enter the construction site.
(3) assembling and installation process to choose qualified raw materials and qualified accessories to ensure the reliability of the use of the building template itself.
(4) to complete the assembly and installation of architectural templates, first of all workers to be self-test after passing the self-test, before the next report to the appropriate recognized by the responsible engineer and supervising engineer checking a process of construction.
(5) of the building template removed to achieve the specifications of the concrete strength.
(6) the selection of release agent: the normal and orderly of the building template construction, and building a template of normal life, to ensure the quality of the concrete surface, and require the use of low-corrosion oil release agent.
