Technical Field

[0001] The embodiments of the utility model belong to the technical field of waterproof and heat-insulating sloping roofs, and more specifically, relate to an anti-slip structure for sloping roofs. Background Art

[0002] At present, during the construction of sloping roofs, due to the large inclination of the sloping roofs and the certain gravity of the structure itself, the waterproof layer, insulation layer or tile roof of the sloping roof building may experience overall slippage and fall off to varying degrees during long-term use. This makes the sloping roof prone to the risk of sliding, so certain anti-slip measures need to be adopted.

However, in this application, the steel bar penetrates the waterproof layer, the waterproof coil is damaged, and rainwater easily penetrates; and the steel plate is used as a pressure plate, and the construction efficiency is low. Utility Model Content

[0005] In view of the above defects or improvement needs of the prior art, the utility model provides an anti-slip structure for a sloping roof. By setting anti-slip steps with a certain spacing and height on the sloping roof, the insulation board and the fine stone concrete protective layer are effectively prevented from sliding off due to their own weight, which not only improves the safety and service life of the insulation board, but also reduces the extra costs and inconvenience caused by repairing and replacing insulation materials.

[0006] In order to achieve the above-mentioned object, the utility model provides an anti-skid structure for a sloping roof, comprising a sloping roof, a cement mortar leveling layer laid on the sloping roof, a waterproof coiled material laid on the cement mortar leveling layer, an insulation board laid on the waterproof coiled material, and a fine stone concrete protective layer poured on the insulation board;

[0007] Starting from the eaves of the sloping roof, upward and parallel to the ridge, an anti-skid step is set every three insulation boards. The anti-skid step is cast integrally with the sloping roof to prevent the insulation board from sliding down due to gravity.

[0008] In one embodiment of the utility model, the cement mortar leveling layer is arranged between the sloping roof and the waterproof membrane, and the insulation board is laid between the waterproof membrane and the fine stone concrete protective layer.

[0009] In one embodiment of the utility model, the insulation board is fixed on the sloping roof by an anti-slip step. Through the support and fixation of the anti-slip step, the insulation board can be firmly fixed on the sloping roof.

[0010] The fine stone concrete protective layer is arranged on the uppermost layer of the sloping roof.

[0011] In one embodiment of the utility model, the height of the anti-slip step is 20 mm lower than the total thickness of the cement mortar leveling layer, the waterproof membrane, the insulation board, and the fine stone concrete protective layer.

[0012] In an embodiment of the present invention, the adjacent anti-slip steps have the same height and the same spacing.

[0013] In one embodiment of the present invention, the anti-slip step is arranged perpendicular to the sloping roof.

[0014] In one embodiment of the present invention, the waterproof coiled material is made of chlorinated polyethylene.

[0015] In one embodiment of the present invention, a sealing material is provided between the waterproof coiled material and the anti-slip step, and the sealing material is a sealing tape.

[0016] In general, the above technical solutions conceived by the utility model can achieve the following beneficial effects compared with the prior art:

[0017] (1) The anti-skid structure of the sloping roof of the utility model effectively prevents the insulation board and the fine stone concrete protective layer from sliding down due to their own weight by setting anti-skid steps at a certain distance and a certain height on the sloping roof, which not only improves the safety and service life of the insulation board, but also reduces the additional costs and inconvenience caused by the maintenance and replacement of insulation materials.

[0018] (2) The anti-skid structure of the sloping roof of the utility model ensures the close connection and overall strength of the anti-skid step and the sloping roof by integrally casting the anti-skid step and the sloping roof. Since the anti-skid step and the sloping roof are integrally formed, no additional formwork is required for fixing, which greatly simplifies the construction process and improves the construction efficiency. At the same time, the integral casting also ensures that the connection between the anti-skid step and the sloping roof is vibrated and compacted, avoiding quality problems such as hollowing and cracking. It avoids the problems of difficult formwork reinforcement, loose vibration, and uneven dimensions and lines in traditional construction.

[0019] (3) The anti-skid structure of the sloping roof of the utility model prevents the waterproof membrane from being penetrated during paving by means of a cast-in-place anti-skid step, thereby ensuring the anti-skid performance and waterproof effect of the sloping roof structure.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0027] In this patent, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0028] The embodiment of the utility model provides an anti-skid structure for a sloping roof, comprising a sloping roof 1, a cement mortar leveling layer 3 laid on the sloping roof 1, a waterproof membrane 4 laid on the cement mortar leveling layer 3, an insulation board 5 laid on the waterproof membrane 4, a fine stone concrete protective layer 6 cast on the insulation board 5, and an anti-skid step 2 cast away from the eaves of the sloping roof 1. This embodiment effectively prevents the insulation board 5 and the fine stone concrete protective layer 6 from sliding down due to their own weight by arranging anti-skid steps 2 with a certain interval and a certain height on the sloping roof 1, which not only improves the safety and service life of the insulation board 5, but also reduces the additional cost and inconvenience caused by repairing and replacing insulation materials.

[0029] Starting from the eaves of the sloping roof 1, upward and parallel to the ridge, an anti-skid step 2 is set every three insulation boards 5. The anti-skid step 2 is 100 mm wide and 20 mm lower than the total thickness of the cement mortar leveling layer 3, the waterproof membrane 4, the insulation board 5, and the fine stone concrete protective layer 6. This ensures that the waterproof membrane has a minimum protective layer thickness and a smooth transition between the anti-skid step and the surrounding structure, avoiding safety hazards caused by excessive height difference and effectively preventing the insulation board and the fine stone concrete protective layer from sliding down due to gravity.

[0030] Optionally, when the distance between the anti-slip step 2 and the roof ridge does not meet the setting requirements, it may not be set.

[0031] The anti-skid step 2 and the sloping roof 1 are supported together with a formwork to pour concrete, thereby forming an integral structure to ensure the stability and integrity of the structure.

[0032] Optionally, the anti-skid step 2 is cast vertically on the sloping roof.

[0033] Optionally, the waterproof coiled material 6 is made of chlorinated polyethylene.

[0034] In the embodiment of the utility model, the anti-skid step 2 and the sloping roof 1 are integrally cast in situ to ensure the close combination and overall strength of the two. Since the anti-skid step 2 and the sloping roof 1 are integrally formed, no additional template is required for fixing, which greatly simplifies the construction process and improves the construction efficiency. At the same time, the integral cast-in-situ also ensures that the connection between the anti-skid step 2 and the sloping roof 1 is vibrated and compacted, avoiding quality problems such as hollowing and cracking. It avoids the problems of difficult template reinforcement, loose vibration, and uneven size and lines in traditional construction.

[0035] The cement mortar leveling layer 3 is arranged between the sloping roof 1 and the waterproof membrane 4. The cement mortar leveling layer 3 plays the role of leveling the base layer, thereby facilitating the smooth laying of the waterproof membrane 4. The leveling base layer not only helps to improve the laying efficiency of the waterproof membrane 4, but also ensures the close fit between the waterproof membrane 4 and the base layer, thereby enhancing the integrity and sealing of the waterproof layer.

[0036] The waterproof membrane 4 is laid flatly and tightly along the cement mortar leveling layer 3 and the anti-skid step to prevent rainwater from penetrating due to gaps in the later stage.

[0037] The insulation board 5 is laid between the waterproof membrane 4 and the fine stone concrete protective layer 6, and the insulation board is fixed on the sloping roof by the anti-slip step 2. Through the support and fixation of the anti-slip step 2, the insulation board 5 can be firmly fixed on the sloping roof, effectively preventing the sliding phenomenon caused by its own weight or other external forces.

[0038] The fine stone concrete protective layer 6 is arranged on the uppermost layer of the sloping roof to protect the internal structure of the sloping roof 1 and prevent external factors such as weather changes, hail and other physical impacts from causing damage to the internal structure.

[0039] Optionally, a steel mesh is provided inside the fine stone concrete protective layer 6 to enhance the strength and service life of the protective layer.

[0040] The utility model provides a construction method for an anti-skid structure of a sloping roof, comprising:

[0041] Step S100: First, a formwork is set up on the base of the sloping roof 1 according to a predetermined position and size, and then a non-slip step 2 of a certain height and width is cast; watering and curing are performed 10 hours after the casting is completed, and when the strength reaches the designed allowable strength, the formwork is removed;

[0042] Step S200: Laying a cement mortar leveling layer 3 on the sloping roof 1: Thoroughly clean and inspect the sloping roof 1 to ensure that the base layer is free of defects such as oil stains, loose objects, and cracks. Subsequently, calculate the required mix ratio of cement mortar according to the actual situation and requirements of the sloping roof 1, and mix and stir strictly according to the proportion. Finally, use professional construction tools to evenly lay the cement mortar on the sloping roof, and use special tools to compact and smooth it until the flatness and smoothness required by the design are achieved. When a certain strength is reached, use cement mortar to round the corners of the anti-slip step 2.

[0043] It should be noted that after the cement mortar leveling layer 3 is laid, it needs to be fully cured to ensure its strength and stability. During the curing period, any form of stepping and heavy pressure on the leveling layer should be avoided to avoid affecting its quality.

[0044] Step S300: Laying the waterproof membrane 4: After the cement mortar leveling layer is completely dry and reaches the designed strength, the waterproof membrane 4 can be laid; apply a layer of cold primer, first lay the detailed structures such as the corners, and then lay the rest from the eaves upwards.

[0045] Optionally, the waterproof membrane 4 may be laid by overlapping and sealed by using the overlapping seams, and the sealing material may be a sealing paste or a sealing tape.

[0046] It should be noted that the laying of waterproofing membrane 4 should be carried out in strict accordance with the construction specifications to ensure that there are no bubbles, wrinkles, hollows and other defects between the membrane and the leveling layer. At the same time, special waterproof glue should be used for pasting and sealing at the joints of the membrane to enhance the integrity and sealing of the waterproof layer. In addition, waterproofing membrane 4 should be laid on sunny days and not on rainy days.

[0047] Step S400: Lay the insulation board 5 to make the joints tight

[0048] Step S500: Laying a protective layer of fine stone concrete 6: Binding a bidirectional steel mesh, placing a cement mortar finished pad at the bottom, leaving a separation joint as required, pouring fine stone concrete, and completing the construction.

[0049] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
