Description

Technical Field

[0001] This utility model relates to the field of rolled material edge pressing structure technology, specifically to a fixed edge pressing structure for building roof waterproofing rolled materials. Background Technology

[0002] In building roofing projects, the fixing and pressing structure of waterproof membranes is a crucial component for ensuring roof waterproofing performance, and its construction quality directly affects the safety and service life of the waterproofing system. Currently, existing fixing and pressing structures for building roof waterproof membranes generally have several defects: some structures use ordinary metal strips and bolts, which have poor corrosion resistance and are prone to rusting and damage when exposed to the outdoor environment for extended periods, leading to loosening of the waterproof membrane and subsequent roof leaks; some fixing and pressing structures lack dedicated membrane fixing and installation frames, resulting in insufficient stability of the waterproof layer and a tendency for displacement and warping; furthermore, the sealing treatment of existing structures is incomplete, only sealing the connection between the strip and the membrane, neglecting easily leaking points such as bolt and hole positions, and the connection between the installation frame and polymer mortar, resulting in poor sealing effects. Rainwater can easily seep in through gaps, damaging the concrete structure and shortening the service life of the waterproofing system. Figure 1 As shown, the waterproof material is directly fixed by pressure strips and bolts, and the waterproof material is a single-layer or multi-layer structure.

[0003] In addition, in the existing fixed edge pressing structure, the pressure strip is prone to interference with the positioning column and side plate of the mounting frame, which leads to the mounting frame becoming loose and the positioning column being damaged, further affecting the fixing effect of the waterproof layer and failing to meet the long-term waterproofing requirements of building roofs. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a fixed pressing structure for waterproof membrane for building roofs, which can effectively solve the problems in the existing technology.

[0005] This utility model provides a fixed edge pressing structure for a building roof waterproof membrane, including a reinforced concrete wall and polymer mortar. The polymer mortar is poured on the outside of the reinforced concrete wall, and a waterproof membrane structure is provided at the bottom of the polymer mortar. The waterproof membrane structure is coated on the reinforced concrete wall, and a pressure strip is provided on the outside of the waterproof membrane structure. The pressure strip, the waterproof membrane structure, and the reinforced concrete wall are connected and fixed by locking bolts. The waterproof membrane structure includes a waterproof layer and an installation frame for fixing the waterproof layer. The pressure strip is a special galvanized corrosion-resistant metal pressure strip, and the locking bolts are corrosion-resistant. Asphalt-based sealant is applied to the closing part, and the asphalt-based sealant covers the connection nodes between the pressure strip and the waterproof membrane structure, the reinforced concrete wall, the connection between the locking bolts and related holes, and the joint gap between the installation frame and the polymer mortar.

[0006] Furthermore, the mounting frame is a frame structure without sides, and positioning posts are fixed on both sides. Multiple sets of bottom holes are opened in the middle of the mounting frame, and side plates are fixed at both ends of the mounting frame. The pressure strip does not interfere with the side plates and positioning posts of the mounting frame, does not affect the fixing of the side plates and the structural integrity of the positioning posts, and the pressure strip is tightly fitted to the waterproof membrane structure.

[0007] Furthermore, the side plate at one end of the mounting bracket is fixed in the polymer mortar, and a pressure strip is fixed on the outside of the polymer mortar; the pressure strip is tightly attached to the surface of the waterproof membrane structure without any curling edges or gaps, ensuring the fixing effect on the waterproof membrane structure.

[0008] Furthermore, a circular hole is provided in the middle of the waterproof layer, and the locking bolt passes through the bottom hole and the circular hole to be connected and fixed to the reinforced concrete wall; the circular hole and the bottom hole are precisely aligned, and the locking bolt is firmly connected to the reinforced concrete wall, the bottom hole and the circular hole without loosening, and without damaging the positioning column.

[0009] Furthermore, the reinforced concrete wall, polymer mortar, waterproof membrane structure, pressure strip, and locking bolts all have complete structures without defects such as damage, loosening, or displacement; the positioning column is undamaged and undeformed, and the side plate is firmly connected to the polymer mortar without loosening.

[0010] Furthermore, the fixing status of the pressure strip, the installation accuracy of the locking bolts, the coverage quality of the asphalt-based sealant, the fixing effect of the side plate of the mounting bracket, the integrity of the positioning column, and the alignment accuracy of the round hole of the waterproof layer and the bottom hole of the mounting bracket all meet the design requirements.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by using special galvanized corrosion-resistant metal strips and corrosion-resistant locking bolts, the corrosion resistance of the entire fixed edge structure is significantly improved, effectively avoiding the problem of rust and damage of ordinary metal parts exposed to the outdoor environment for a long time, extending the service life of the waterproof system, and ensuring the fixing reliability of the strips and bolts, preventing the waterproof membrane from loosening.

[0012] This utility model features a dedicated mounting bracket for fixing the waterproof layer. The positioning posts on both sides of the mounting bracket can accurately position the waterproof layer, and the side plates at both ends are fixedly connected with polymer mortar, further improving the fixing stability of the waterproof layer and preventing displacement or lifting of the waterproof layer, thus ensuring the waterproof effect. At the same time, the pressure strip does not interfere with the side plates and positioning posts of the mounting bracket, effectively protecting the structural integrity of the mounting bracket and preventing loosening of the mounting bracket or damage to the positioning posts due to interference.

[0013] This utility model provides an asphalt-based sealant at the joint, which fully covers the connection nodes between the strip and the waterproof membrane structure, the reinforced concrete wall, the connection between the locking bolts and related holes, and the joint between the mounting bracket and the polymer mortar. This achieves all-round sealing, effectively avoids the hidden danger of rainwater seeping into the gaps, protects the concrete structure from damage, and further improves the safety performance of the waterproof system.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example: A fixed edge pressing structure for a building roof waterproof membrane, see attached figure. Figure 2 -Appendix Figure 4A fixed edge pressing structure for a building roof waterproof membrane includes a reinforced concrete wall 1 and a polymer mortar 2. The polymer mortar 2 is poured on the outside of the reinforced concrete wall 1 to protect the reinforced concrete wall 1 and provide a fixed foundation for the installation frame 52. The pouring thickness of the polymer mortar 2 meets the design requirements to ensure that it is tightly bonded to the reinforced concrete wall 1 without hollow areas or cracks.

[0020] A waterproof membrane structure 5 is installed at the bottom of the polymer mortar 2. The waterproof membrane structure 5 is coated on the reinforced concrete wall 1, fully covering the bottom and side joints of the reinforced concrete wall 1. The waterproof membrane structure 5 includes a waterproof layer 51 and an installation frame 52 for fixing the waterproof layer 51. The waterproof layer 51 uses a waterproof membrane that meets the roof waterproofing standards to ensure waterproof performance. The installation frame 52 is used to position and fix the waterproof layer 51 to prevent the waterproof layer 51 from shifting or lifting.

[0021] The mounting bracket 52 is a frame structure without sides, which facilitates its fit and fixation to the waterproof layer 51. Positioning posts 522 are fixed to both sides of the mounting bracket 52, perpendicular to the mounting bracket 52, for precise positioning of the waterproof layer 51 and to prevent displacement during use. Multiple sets of bottom holes 521 are formed in the middle of the mounting bracket 52, the number and spacing of which meet design requirements, for use with locking bolts 4 to achieve installation and fixation. Side plates 523 are fixed to both ends of the mounting bracket 52, perpendicular to the mounting bracket 52. One side plate 523 is fixed within the polymer mortar 2, ensuring the stability of the mounting bracket 52 and thus guaranteeing the fixation effect of the waterproof layer 51.

[0022] A pressure strip 3 is provided on the outer side of the roll waterproof structure 5. The pressure strip 3 is a special galvanized corrosion-resistant metal pressure strip with good corrosion resistance and structural strength, which can adapt to the harsh outdoor environment for a long time. The pressure strip 3 fits tightly with the roll waterproof structure 5 without curling edges or gaps, ensuring the fixation of the roll waterproof structure 5. At the same time, the pressure strip 3 does not interfere with the side plate 523 and positioning post 522 of the mounting frame 52, does not affect the fixation of the side plate 523 to the polymer mortar 2, and will not damage the structural integrity of the positioning post 522.

[0023] The pressure strip 3, the waterproof membrane structure 5, and the reinforced concrete wall 1 are connected and fixed by locking bolts 4. The locking bolts 4 are corrosion-resistant and work in conjunction with the galvanized corrosion-resistant metal pressure strip to further enhance the corrosion resistance of the entire structure. A round hole is opened in the middle of the waterproof layer 51, which is precisely aligned with the bottom hole 521 of the mounting bracket 52. The locking bolts 4 pass through the pressure strip 3, the round hole of the waterproof layer 51, and the bottom hole 521 of the mounting bracket 52 in sequence, and are firmly connected to the reinforced concrete wall 1. The connection is firm and there is no looseness. Moreover, the installation of the locking bolts 4 does not damage the positioning column 522.

[0024] Asphalt-based sealant is applied to the finishing area. Asphalt-based sealant has good sealing performance and adhesion, and can effectively fill various gaps. Its coverage includes the connection nodes between the pressure strip 3 and the waterproof membrane structure 5, the connection nodes between the pressure strip 3 and the reinforced concrete wall 1, the connection between the locking bolt 4 and the bottom hole 521, the round hole, and the joint between the side plate 523 of the mounting bracket 52 and the polymer mortar 2, so as to achieve all-round sealing and prevent rainwater leakage.

[0025] In this embodiment, the reinforced concrete wall 1, polymer mortar 2, waterproof membrane structure 5, pressure strip 3, and locking bolt 4 all have complete structures without defects such as damage, loosening, or displacement; the positioning column 522 is undamaged and undeformed, and the side plate 523 is firmly connected to the polymer mortar 2 without loosening; the fixing status of the pressure strip 3, the installation accuracy of the locking bolt 4, the coverage quality of the asphalt-based sealant, the fixing effect of the side plate 523 of the mounting frame 52, the integrity of the positioning column 522, and the alignment accuracy of the round hole of the waterproof layer 51 and the bottom hole 521 of the mounting frame 52 all meet the design requirements, ensuring that the entire fixed edge structure can play a stable waterproof role for a long time.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
