Problems solved by technology
Once the strength of the concrete has not reached the strength required by the code, the formwork will be removed, and the concrete structure will be damaged due to premature loading and disturbance of formwork removal. The project brings hidden dangers and becomes a lifelong defect of concrete, which affects the service life of concrete, especially if the base form is removed in violation of regulations, it will seriously cause collapse and lead to vicious liability accidents
Premature removal of formwork will not only damage the shape of concrete, but also affect the normal growth of concrete strength

Embodiment Construction
[0025] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the invention.
[0026] Such as figure 1 The illustrated embodiment 1 is a prefabricated protective layer for concrete components, the concrete protective layer is composed of four prefabricated concrete slabs 2 surrounded by columns and a stiffening connection section 3, and the two columns are connected through the stiffening The section 3 is connected, and there is a limit block inside the stiffened connection section 3 to limit the position of the precast concrete slab 2, and at least a pair of holes 4 are reserved on the concrete protective layer, and tie rods 6 pass through the concrete protective layer through the holes 4.
[0027] Such as figure 2 In the shown embodiment 2, the concrete protective layer is placed outside ...

The invention discloses a precast protecting layer for a concrete member. A concrete protecting layer is composed of column bodies defined by a plurality of precast concrete slabs (2), and a stiffenedconnecting section (3), the two column bodies are connected through the stiffened connecting section (3), the stiffened connecting section (3) is internally provided with limiting blocks for limitingthe positions of the precast concrete slabs (2), holes (4) are reserved in the precast concrete slabs (2) of the concrete protecting layer, tie rods (6) penetrate through the concrete protecting layer through the holes (4), then concrete is poured and cured, and formwork removing is not needed.
Description
technical field [0001] The invention relates to a beam-slab-column template, in particular to a prefabricated protective layer for concrete components. Background technique [0002] In the prior art, the pouring of concrete beams and columns of frame buildings has always been carried out by formwork pouring, that is, the formwork and steel bars are installed according to the construction requirements, and then concrete is poured into the mold, and the formwork is removed after the concrete is completely hardened. The whole construction is over. There are many drawbacks in the above method. First of all, it is necessary to remove garbage, soil and other debris on the formwork, especially the wooden formwork, which needs to be soaked in advance. Secondly, when removing the formwork, it is necessary to ensure that the concrete is completely dry and hard, and great care must be taken when removing it. Once the strength of the concrete has not reached the strength required by ...
