4. A method for manufacturing a protective cover plate for a reserved hole as claimed in claim 1, wherein the upper surface of the cover plate is coated with red and white warning paint.

5. A reserved hole protective cover plate manufacturing method as claimed in claim 1, wherein the upper surface of the cover plate is sprayed with a 'movement forbidden' warning statement mark.

6. A method for manufacturing a protective cover plate for a reserved hole as claimed in claim 1, wherein two battens can be adopted as the coping battens, so that the two battens are fixed on the upper surface of the template at a certain distance from each other.

7. A method for making a protective cover plate for a reserved hole as claimed in claim 1, wherein the side length of the cover plate is less than 500 mm.

Technical Field

The invention relates to a manufacturing method of a protective cover plate, in particular to a manufacturing method of a protective cover plate with a reserved hole.

Background

The hole is reserved when the main body construction and the secondary structure construction of the industrial and civil buildings are carried out. The cover plate is complicated to detach because of no anchoring during the protection of the reserved hole in construction, and is easy to shift, or the cover plate has poor bearing capacity, the plate body is broken, and the cover plate is not firm.

Chinese patent CN201720739779.8U discloses a reserved hole protection device in 2018, 3, 16, which includes an insert block and a cover plate connected to the insert block; the inserting block can be inserted into the reserved hole; the covering plate can cover the reserved hole opening of the reserved hole. Although this technical scheme's overlay can cover the reservation entrance to a cave of reserving the hole, its sign is unclear, is easily moved and causes building site construction potential safety hazard.

The known protective cover plate for a reserved hole has various inconveniences and problems.

Disclosure of Invention

The invention aims to provide a safe and reliable manufacturing method of a reserved hole protective cover plate.

In order to achieve the purpose, the technical solution of the invention is as follows:

a method for manufacturing a protective cover plate of a reserved hole is characterized by comprising the following steps:

a. manufacturing a cover plate by using a template according to the size of the hole, wherein the length and the width of the template are the sum of the size of the cross section of the hole and 200 mm;

b. manufacturing a capping batten, enabling the length of the capping batten to be equal to that of the template, and fixing the capping batten on the central part of the upper surface of the template by using a nail;

c. manufacturing two cover bottom battens, enabling the lengths of the two cover bottom battens to be the same, enabling the length of each cover bottom batten to be equal to the width of the template minus 200mm, and fixing the two cover bottom battens on the positions on two sides of the width direction of the lower surface of the template respectively by using nails, wherein the distance between each cover bottom batten and the edge is 100 mm;

d. the cover top battens on the upper surface of the template and the cover bottom battens on the lower surface of the template are vertically arranged.

The manufacturing method of the reserved hole protective cover plate can be further realized by adopting the following technical measures.

In the method, the thickness of the template is more than or equal to 15 mm.

In the method, the specification of the flitch is not less than 50mm × 100 mm.

The method, wherein the cover plate is coated with red and white warning paint on the upper surface.

The method as described above, wherein the cover plate upper surface is coated with a "no movement" warning sentence mark.

In the method, two capping battens can be used to fix the capping battens on the upper surface of the formwork at a certain distance.

The method of the preceding, wherein the side length of the cover plate is < 500 mm.

After the technical scheme is adopted, the manufacturing method of the reserved hole protective cover plate has the following advantages:

1. the cover plate has simple structure and convenient manufacture;

2. the cover plate is safe and reliable and is tightly protected, the phenomenon of cover plate displacement is avoided, and the construction safety is ensured.
