[0022] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 3 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the drawings in the specification.

[0023] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0024] The utility model is a revolving roof air-permeable concrete pier mold with an overall height of about 350 mm. It can be improved according to actual construction needs. Its main material is angle steel. The angle steel model uses an angle steel plate with a length of 1.5 m, a thickness of 3 mm, and a width of 50 mm. The overall vertical section is a trapezoid.

[0025] The entire pier protection mold is divided into two symmetrical pier protection devices. The two pier protection devices have the same structure and are symmetrically arranged. They can be disassembled when not in use and can be docked when in use. The entire pier protection mold is structured in a prism shape, and the prism cross-section is triangular, quadrilateral, hexagonal, octagonal, etc.

[0026] The pier protection device includes a semi-prismatic pier 1. After the two piers 1 are aligned, a column ventilation pipe 4 is clamped. There is a casting hole between the ventilation pipe 1 and the side wall of the pier 1. The casting hole 2 is at the longitudinal center of each pier protection device. A concrete baffle 3 of the same shape is fixed above the pier 1 to prevent the concrete from overflowing and flowing out when pouring concrete. A clamp 5 is concentrically arranged just above the casting hole 2. The clamp 5 is used to fix the ventilation pipe 4. The diameter of the casting hole 2 is larger than the diameter of the clamp 5. The extra space is used to pour concrete. After the two clamps 5 are aligned, a locking hole 6 is provided on the side of the clamp 5 to further fix and lock the ventilation pipe 4 to prevent the ventilation pipe 4 from deviating.

[0027] A top hole is opened on the concrete baffle plate 3, and a top rod 7 is slidably installed in the top hole. One end of the top rod 7 is placed in the concrete baffle plate 3, and the other end is placed outside the concrete baffle plate 3. A clamp 5 connected to the top rod 7 is provided on one side inside the concrete baffle plate 3. The clamp 5 and the top rod 7 are detachably connected, such as friction plug-in or threaded connection. A push rod 8 connected to the top rod 7 is provided on one side outside the concrete baffle plate 3. The push rod 8 is hinged to the top rod 7, and a handle 9 is hinged at the other end of the push rod 8. The handle 9 is L-shaped, and the L-shaped intersection is hinged to the push rod 8. A support rod 10 is also hinged at this position, and the other end of the support rod 10 is fixed to the pier 1.

[0028] Locking plates 11 are extended from both ends of the concrete baffle 3. The locking plates 11 are provided with docking holes 12 for installing fastening bolts.

[0029] A larger prismatic extension plate 13 is fixed on the upper surface of the pier 1, so that it is convenient to hold it by hand for rotation and movement.

[0030] A bottom plate groove 14 is fixed at the lower end of the guard pier 1. If concrete overflows from the concrete baffle 3 during pouring, it can flow into the bottom plate groove 14 for collection and treatment, and will not flow onto the roof arbitrarily to cause unevenness, bulges, etc. Vertical fixing holes 15 are fixed in the bottom plate groove 14 to fix the guard pier 1 when pouring the roof vents. Reinforcement plates 16 are fixed at both ends of the bottom plate groove 14. Reinforcement holes 17 are opened on the reinforcement plates 16. One is to strengthen the overall strength, the second is to facilitate docking, and the third is to lock the left and right guard pier devices by tightening bolts after docking.

[0031] The guard pier can be cast on site to increase the bonding strength with the substrate and prevent water leakage.

[0032] Production process:

[0033] Determine the pier height and side length according to the plan requirements, use Revit or other software to release the mold template, process and cut the angle steel and steel plate template according to the template size, weld the cut angle steel into a hexagon with an electric welder, and grind the weld smooth, select the steel plate template, cut it into 6 trapezoidal steel templates as required, and weld them together. The mold is divided into two sets, the left and right sets, and the two pier protection devices are connected by bolts.

[0034] Working principle:

[0035] Before pouring, apply mold release agent in the pouring hole 2, a leveling layer should be made at the root of the ventilation pipe 4, the ventilation pipe 4 should be located in the center of the pier, and the piers of the same type and similar specifications should be basically the same in height and arranged in rows.

[0036] When constructing the roof ventilation duct, hold the extension plate 13 by hand to place the two left and right pier devices of the present application at the construction position, place them concentrically, align the left and right pier devices, fix the two piers 1 with bolts through the fixing holes 15, and then tighten the docking holes 12 on the locking plate 11, and tighten the reinforcement holes 17 on the reinforcing plate 16, then hold the handle 9 and push it forward, the handle 9 drives the push rod 8 from the tilting device downward to gradually change to a horizontal state, at the same time, the push rod 8 pushes the top rod 7 to move inward, so that the two clamps 5 clamp the ventilation duct 4, and then tighten it with bolts through the locking holes 6, and then pour concrete into the pouring hole 2, the concrete baffle 3 is used to prevent concrete from overflowing, in case of concrete overflow, the overflowed concrete can flow into the bottom plate groove 14, if the ventilation duct 4 of different diameters is constructed next time, the appropriate clamp 5 should be replaced in advance.

[0037] After demoulding, the concrete surface is polished and corrected, waterproof putty is applied, the surface is painted with waterproof paint that is coordinated with the roof decoration, and the joint between the pier 1 and the ventilation pipe 4 is glued.

[0038] The quality standard is that the guard pier 1, the ventilation pipe 4 and the roof should be tightly combined, the joints should be clear, the paint should be evenly applied, the color should be coordinated, and the glue joints should be even and smooth.

[0039] The utility model adopts angle steels for combined assembly to form a standardized mold, which can be used to make casting holes with different side lengths and different diameters. The whole is a hexagonal column, and polygonal concrete piers such as triangles and quadrilaterals can also be constructed.

[0040] The utility model has the advantages of simple overall structure, convenient manufacture, portability, easy operation, detachability, low cost and high working efficiency.

[0041] The utility model can improve the construction quality of the roof air vents through the concrete pier mold, and can conveniently carry out concentric positioning of the ventilation pipe through the clamp. The detachable clamp can facilitate the replacement of clamps of different diameters to adapt to channel pipes of various diameters.
