[0024] Example 1

[0025] Please see Figure 1 , Figure 2 A roof exhaust pipe protection block forming mold includes a mold body 100, the mold body 100 including a hollow receiving chamber 110 through which the exhaust pipe passes, the mold body 100 having a first baffle and a second baffle 120 at one end of the hollow receiving chamber 110 near the roof along the axial direction, the inner sidewall of the first baffle being formed in the hollow receiving chamber 110, the second baffle 120 being arranged radially outside the first baffle along the hollow receiving chamber 110, the first baffle and the second baffle 120 enclosing each other to form an overflow prevention space 300 surrounding the hollow receiving chamber 110.

[0026] In this embodiment, as Figure 1As shown, the mold body 100 is vertically placed on the roof during work, the mold body 100 is a hollow structure including a hollow containing bin 110, and the bottom end of the mold body 100 is provided with a first blocking body and a second blocking body 120, wherein the first blocking body is located on the inner side of the mold body 100, and the second blocking body 120 is located on the outer side of the mold body 100. In use, the mold body 100 is sleeved on the exhaust pipe from above, so that the exhaust pipe passes through the hollow containing bin 110, and one end of the first blocking body and the second blocking body 120 is in contact with the roof. The inner side wall of the first blocking body is located in the hollow containing bin 110, and the second blocking body 120 is arranged around the first blocking body, and there is a gap between the first blocking body and the second blocking body 120. When the first blocking body and the second blocking body 120 are in contact with the roof, the outer side wall of the first blocking body and the inner side wall of the second blocking body 120 form a spill-proof space 300. During pouring work, the concrete or cement mortar is poured into the hollow containing bin 110 through the opening at the upper part of the mold body 100 to wrap the exhaust pipe to form a protective pier. During pouring, the first blocking body and the second blocking body 120 are in contact with the roof, which increases the contact area of the mold body 100 with the roof, and there is a gap between the first blocking body and the second blocking body 120, which improves the support stability of the mold body 100. The impact of the concrete or cement mortar on the inner wall of the mold body 100 during pouring can be effectively reduced, so that the mold body 100 is offset or warped, thereby reducing the overflow of the concrete or cement mortar. In addition, the inner wall of the first blocking body is formed in the hollow containing bin 110, thereby playing a first blocking role to prevent the overflow of the concrete or cement mortar. When the concrete or cement mortar overflows from the first blocking body, it enters the spill-proof space 300, and the second blocking body 120 plays a second blocking role to make the overflowed concrete or cement mortar accumulate in the spill-proof space 300, thereby avoiding the spread of the concrete or cement mortar on the roof. When the strength of the concrete or cement mortar reaches the requirement, the mold is removed, thereby completing the production of the protective pier.

[0027] The above structure sets the first blocking body and the second blocking body 120 at the bottom of the mold body, which increases the contact area with the roof, and there is a gap between the first blocking body and the second blocking body 120, which further improves the support stability of the mold body on the roof. The first blocking body and the second blocking body 120 play a double blocking role, and the existence of the spill-proof space 300 between the first blocking body and the second blocking body 120 effectively prevents the overflow of the concrete or cement mortar from the mold body 100 and spreads on the roof, thereby avoiding the pollution of the roof. In addition, the overflowed concrete or cement mortar accumulates in the spill-proof space 300, which is convenient for cleaning and improves the production efficiency of the protective pier.

The generatrix of the axial section of the mold shell 130 is a curved structure.

[0029] In the embodiment, the outer shape structure of the mold body 100 is a curved structure, and the outer shape structure of the hollow accommodating cavity 110 is also a corresponding curved structure, so that the structure of the protective pier made is beautiful in modeling, in addition, the diameter of the bottom of the hollow accommodating cavity 110 of the mold body 100 is greater than the diameter of the top, so as to ensure the structural strength of the protective pier made, and the annular baffle 210 is connected to the inner wall of the bottom of the mold shell 130, wherein the axial direction of the annular baffle 210 is vertical and consistent with the axial direction of the hollow accommodating cavity 110, one end of the annular baffle 210 is connected with the inner wall of the mold shell 130, the other end extends vertically and contacts with the roof, and the inner wall of the annular baffle 210 forms part of the hollow accommodating cavity 110, so that the bottom of the protective pier made is a cylindrical structure, which improves the aesthetic degree while ensuring the structural strength, and the annular baffle 210 as a first blocking body can block the concrete, the mold shell 130 as a whole is a curved structure, and the edge skirt structure is formed on the mold shell 130 from the connection point of the mold shell 130 with the annular baffle 210 to the edge of the mold shell 130, the edge skirt structure wraps the annular baffle, the edge skirt structure forms a second blocking body 120, the second blocking body 120 and the mold shell 130 are an integral structure, which is convenient for making, wherein, since the mold shell 130 as a whole is a curved structure, in the axial section, the annular baffle 210 and the second blocking body 120 form a triangular spill-proof space 300 structure, which further improves the support stability, at the same time, the second blocking body 120 is a curved structure, which increases the contact area with the roof, and further improves the blocking effect.
