Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a simple construction mold for waterproof protective layer of pipes on roofs. Background Technology

[0002] The roof-mounted pipes in the roofing sub-project of building construction, such as rainwater and sewage vent pipes and roof exhaust risers, are essential components of roofing projects. They must ensure both aesthetics and leak-proof functionality, which is crucial to the construction quality of roofing projects and is a key and challenging aspect of roofing project construction management.

[0003] If an existing roof project does not have a waterproof protective layer, the waterproof layer and its additional layers are prone to aging and damage, leading to roof leaks and failing to meet the design service life requirements for roof waterproofing. If a wire mesh plastering method is used, it is prone to cracking in a short time due to insufficient strength, affecting the appearance and causing the waterproof layer to be easily damaged and leak, also failing to meet the design service life requirements for roof waterproofing. The operation is cumbersome, labor costs are high, and it is difficult to guarantee the appearance quality. If concrete is poured into disposable sleeves purchased and processed by oneself, the additional cost is high, and the structure, shape, and surrounding gaps need to be treated separately, which is not aesthetically pleasing or practical. If a spray coating method is used, durability, appearance quality, and shape cannot be guaranteed. Therefore, a construction mold is needed to assist in the manufacture of the pipe waterproof protective layer.

[0004] A roof-mounted pipe forming mold disclosed in Chinese patent document CN211143540U includes a base, which is a cuboid with openings at the top and bottom. Four upward-extending arc-shaped steel templates are provided around the four sides of the base, with a square opening at the top. The base and the arc-shaped steel templates are divided into a left half and a right half along their length. Positioning pins are provided on both the left and right half, and a fixing pull ring is provided in the middle of each half. The fixing pull ring sits on the parting surface, half on the left half and the other half on the right half. This utility model uses a roof-mounted pipe forming mold formed by one-time welding, solving problems such as inadequate protection of waterproof membranes for roof-mounted pipes, easy cracking of the protective layer, and low efficiency of brickwork protection in traditional methods. However, the protective layer produced by this roof-mounted pipe forming mold is connected to a horizontal surface, which easily leads to cracking.

[0005] To address the shortcomings of the existing technology, providing a simple construction mold for waterproof protective layers of pipes on roofs is a problem worthy of research. Utility Model Content

[0006] The purpose of this invention is to overcome the drawback that the protective layer is easily cracked when connected to a horizontal surface. It provides a simple construction mold for waterproof protective layer of pipes on the roof, which achieves good molding effect and is not easy to crack.

[0007] The objective of this utility model is achieved through the following technical solution: A simple construction mold for waterproof protective layer of pipes on roof includes a horizontal surface of the building, a pipe passing through the horizontal surface, and two semi-circular molds fitted on the outside of the pipe. It also includes connecting plates set on both sides of the two semi-circular molds and an extension fixedly connected to the bottom of the semi-circular molds.

[0008] The combined shape of the two semicircular molds is a frustum. The minimum inner diameter of the combined semicircular molds is greater than the outer diameter of the pipe to be protected. By setting two combined frustum-shaped semicircular molds and placing them on the outside of the pipe, concrete is poured into the molds to form a frustum-shaped waterproof protective layer, which seals the gap between the building floors and the pipe, thus playing a role in sealing and waterproofing.

[0009] The connecting plates on the two semicircular molds are matched in position and shape. The connecting plates are provided with connecting holes. By setting connecting plates with connecting holes on the two semicircular molds, during construction, the two semicircular molds are combined on the outside of the pipe. Then, bolts or wires are used to pass through the connecting holes to combine the two semicircular molds with connecting plates, so that the two semicircular molds form a frustum space. Concrete is then poured into the frustum space to form a waterproof protective layer.

[0010] The extension surrounds the outer side of the bottom of the semi-circular mold. The inner side of the extension is horizontal, and the outer side of the extension bends upward. By setting the extension on the outer side of the bottom of the semi-circular mold, a separation seam is left between the bottom of the waterproof protective layer and the horizontal surface, separating it from other horizontal surfaces. This avoids the waterproof protective layer from cracking due to thermal expansion and contraction during use, and also makes it more aesthetically pleasing.

[0011] The bottom of the waterproof protective layer inside the semi-circular mold is filled with caulking compound between itself and the horizontal surface, and the top of the waterproof protective layer inside the semi-circular mold is filled with sealant between itself and the pipe. By applying caulking compound between the waterproof protective layer and the horizontal surface, the expansion joint is filled, preventing cracking at the root of the protective layer and improving the sealing performance of the waterproof protective layer.

[0012] Positive and beneficial effects:

[0013] 1. This simple construction mold for waterproof protective layer of roof pipes is simple in design, easy to manufacture, extremely low in cost, and easy to operate, which significantly saves the labor cost of the project. It has good forming effect, uniform appearance quality, and good durability, which greatly ensures the durability and waterproof performance of the joints of the waterproof layer. Moreover, it is also convenient to apply paint decoration later and has a good appearance.

[0014] 2. The simple construction mold for the waterproof protective layer of the roof pipe has an extension on the outer side of the bottom of the semi-circular mold, which leaves a separation joint between the bottom of the waterproof protective layer and the horizontal surface, separating it from other horizontal surfaces. This avoids cracking of the waterproof protective layer due to thermal expansion and contraction during use, and also makes it more aesthetically pleasing.

[0015] 3. The simple construction mold for the waterproof protective layer of the roof pipes is used to apply caulking compound between the waterproof protective layer and the horizontal surface to fill the gap, prevent cracking at the root of the protective layer, and improve the sealing performance of the waterproof protective layer.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0019] like Figures 1 to 4 As shown, a simple construction mold for waterproof protective layer of pipes on the roof includes a horizontal surface 1, a pipe 2 passing through the horizontal surface 1, and two semi-circular molds 3 sleeved on the outside of the pipe. It also includes connecting plates 4 set on both sides of the two semi-circular molds 3, and an extension 5 fixedly connected to the bottom of the semi-circular molds 3.

[0020] like Figure 1 and Figure 2As shown, the combined shape of the two semicircular molds 3 is a frustum. The minimum diameter of the inner side of the combined semicircular molds 3 is greater than the outer diameter of the pipe to be protected. By setting two semicircular molds 3 that are combined into a frustum shape and placing them on the outside of the pipe, concrete is poured into the molds to form a frustum-shaped waterproof protective layer, which seals the gap between the building floors and the pipe, thus playing a role in sealing and waterproofing. Furthermore, the upper and lower diameters of the semi-circular mold forming the frustum are D+100mm and D+200mm respectively, where D is the diameter of the pipe exiting the roof.

[0021] like Figure 1 As shown, the connecting plates 4 on the two semi-circular molds 3 are matched in position and shape. The connecting plates 4 are provided with connecting holes 6. By setting the connecting plates 4 with connecting holes 6 on the two semi-circular molds 3, during construction, the two semi-circular molds 3 are combined on the outside of the pipe 2. Then, bolts or wires are used to pass through the connecting holes 6 to combine the two semi-circular molds 3 with connecting plates 4, so that the two semi-circular molds 3 form a frustum space. Then, concrete is poured into the frustum space to form a waterproof protective layer. The mold is simple in design, easy to manufacture, and extremely low in cost. It is easy to operate, significantly saving on engineering labor costs. It produces good molding results, with uniform appearance quality and good durability, greatly ensuring the durability and waterproof performance of the waterproof layer joints. Furthermore, it is convenient to apply paint decoration later, resulting in a good appearance. Example 2

[0022] like Figures 1 to 3 As shown, the extension 5 surrounds the outer side of the bottom of the semi-circular mold 3. The inner side of the extension 5 is horizontal, and the outer side of the extension 5 is bent upward. By setting the extension on the outer side of the bottom of the semi-circular mold 3, a separation seam is left between the bottom of the waterproof protective layer and the horizontal surface, which is separated from other horizontal surfaces. This avoids the waterproof protective layer from cracking due to thermal expansion and contraction during use, and also makes it more aesthetically pleasing. Furthermore, the width of the horizontal portion of extension 5 is two centimeters, and the height of the bent portion of extension 5 is five centimeters. This limits the width of the partition joint formed by the mold, effectively resists thermal expansion and contraction and drying shrinkage stress, prevents cracking at the root of the protective layer, provides ideal operating space for the filling of flexible sealing material, and ensures the construction quality and durability of the waterproof seal. Example 3

[0023] like Figure 4 As shown, the bottom of the waterproof protective layer inside the semi-circular mold 3 and the horizontal surface 1 are filled with caulking compound 7, and the top of the waterproof protective layer inside the semi-circular mold 3 and the pipe 2 are filled with sealing compound 8. By setting caulking compound 7 between the waterproof protective layer and the horizontal surface 1, the separation joint is filled, preventing cracking at the root of the protective layer and improving the sealing performance of the waterproof protective layer.

[0024] The working principle of this utility model is as follows: S1. During construction, the two semi-circular molds 3 are combined on the outside of the pipe 2; S2. Use bolts or wires to pass through the connecting hole 6 to merge the two semi-circular molds 3 with connecting plates 4, so that the two semi-circular molds 3 form a frustum space. S3. Pour concrete into the space of the truncated cone to form a waterproof protective layer. It has a simple shape, is easy to make, has a very low cost, is easy to operate, and significantly saves on engineering labor costs. S4. After removing the mold, fill the gap between the waterproof protective layer and the horizontal surface 1 with caulking compound 7, and place the sealing compound 8 between the protective layer and the pipe 2 to fill the gap, prevent the root of the protective layer from cracking, and improve the sealing performance of the waterproof protective layer.

[0025] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
