Description

Technical Field

[0001] The utility model relates to the technical field of slope roof structure construction, in particular to an anti-skid structure for a planting roof with a large slope. Background Art

[0002] In building construction, planting on sloping roofs is a common construction method. When the slope of the planted roof is between 20% and 50%, the construction is usually carried out according to the methods and related requirements of Atlas 14J206 "Planted Roof Building Structures" on pages 2-5. This method requires pre-embedded anti-skid steel bars on the structural plate, and a metal retaining plate perpendicular to the slope direction is set on the waterproof protective layer. The retaining plate is connected to the anti-skid steel bars, and the retaining plates are connected by flat steel tie bands. At the same time, a precast concrete retaining wall or retaining plate is set near the parapet, which is combined with the retaining plate along the slope to play an anti-skid role. The anti-slip steel bars on the plate, perpendicular to the structural surface, need to pass through the waterproof protective layer. During waterproofing construction, holes need to be left at the steel bar positions and reinforcement measures need to be taken, which greatly increases the difficulty of construction and weakens the waterproofing effect. At the same time, it increases the risk of leakage. The upward anti-slip steel bars also increase the construction risk for workers on roofs with steep slopes. The spacing between metal retaining plates is between 1200mm and 1500mm, and may even be less than 1200mm. The flat steel tie strips are 800mm in center and are set along the slope. In order to increase the anti-slip effect, the spacing will be appropriately increased. Compared with concrete retaining walls, the amount of steel used for the same anti-slip effect is relatively large.

[0003] Among the existing technologies and patents, for example, the utility model patent with application number CN201320588426.4 discloses a roof greening anti-skid structure, where multiple sets of anti-skid bases are installed on the roof body, and the anti-skid bases are arranged in a horizontal or staggered manner. The anti-skid bases are below the drainage board and can only serve as anti-skid measures for the construction method below the drainage board, and cannot produce anti-skid effects on the planting soil; there is no drainage measure at the anti-skid base position, which is easy to cause water accumulation, which will penetrate into the lower structural layer through the gaps for a long time, affecting the use function. The invention patent application with application number CN202210622941.3 discloses a multi-slope planting roof structure and its construction method, where the anti-skid facilities are arranged on the roof, and are arranged differently according to the slope grade of the planting roof. The setting method includes anti-skid piers of columnar structures and anti-skid strips of strip structures that are arranged at intervals between the soil layers and connected to the roof; thereby reinforcing and preventing the soil layer and the protective layer and thermal insulation layer arranged on the roof. This method is an inverted roof, and the waterproof layer is set below the insulation layer. Due to the long-term storage of water in the soil, water will seep between the insulation and waterproof layers, and the plant roots will pass through the gaps in the protective layer and penetrate into the insulation layer, which will affect the insulation effect.

[0004] The above-mentioned existing technologies and patents all have certain problems that are difficult to solve to a greater or lesser extent. For this reason, the applicant has proposed an anti-slip structure for a steep-slope planting roof based on the needs of planting on steep-slope roofs, which can solve the above-mentioned problems well, and solve the problems of difficulty in waterproof construction, increased safety hazards in construction operations, and reduced waterproof quality caused by the connection components pre-buried in the structural layer at the existing steep-slope planting roof nodes; solve the problem that the connection components pre-buried in the waterproof protective layer are prone to tearing the waterproof protective layer during use, thereby reducing the anti-slip and waterproof effects; solve the problem that the existing node method uses a large amount of steel; and solve the problem of poor drainage at the concrete retaining wall location.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0035] like Figure 1 As shown, a large slope planting roof anti-skid structure is shown, the structure is provided with a reinforced concrete retaining wall 1, a pebble drainage ditch 2, an L-shaped steel plate 3, a mortar leveling layer 4, a waterproof layer 5, a puncture-resistant waterproof layer 6, a mortar waterproof protective layer 7, a drainage board 8, an isolation layer 9, a planting soil layer 10, an insulation board 11, a reinforced concrete roof panel 12, a fine stone concrete waterproof protective layer 13 and an anti-skid component 16, as shown Figure 1As shown, the anti-skid structure of the steep slope planting roof is set on the steep slope roof of 20°-50°, and a reinforced concrete retaining wall 1 is vertically set on the steep slope roof in a plum blossom structure. The reinforced concrete retaining wall 1 is constructed synchronously with the steep slope roof structure plate to increase the integrity. As shown, after the reinforced concrete retaining wall 1 and the steep slope roof structure plate meet the design strength, the insulation board 11, the reinforced concrete roof panel 12, the mortar leveling layer 4, and the waterproof layer 5 are sequentially installed on the side of the reinforced concrete retaining wall 1 and the outer side of the steep slope roof structure plate. , puncture-resistant waterproof layer 6, fine stone concrete waterproof protective layer 13, drainage board 8, isolation layer 9 and planting soil layer 10 are constructed; as shown, on the top of the reinforced concrete retaining wall 1, the mortar leveling layer 4, waterproof layer 5, puncture-resistant waterproof layer 6, mortar waterproof protective layer 7, drainage board 8, isolation layer 9 and planting soil layer 10 are constructed in sequence; pebble drainage ditches 2 are set on the upper side and both sides of the reinforced concrete retaining wall 1, an L-shaped steel plate 3 is set on the upper side of the reinforced concrete retaining wall 1, and an anti-slip component 16 is set in the planting soil layer 10.

[0036] like Figure 2 As shown, the anti-skid structure of the steep slope planting roof is provided with a reinforced concrete retaining wall 1. The plane size of the reinforced concrete retaining wall 1 is 3000mm×500mm, the height is 100mm higher than the top surface of the adjacent drainage board, the length direction is perpendicular to the slope direction of the steep slope roof, and a plum blossom structure is adopted. The projection of the reinforced concrete retaining wall 1 in the slope direction has neither gaps nor overlaps. The net distance of the reinforced concrete retaining wall 1 in the slope direction is 3000mm, which can be adjusted according to the actual situation of the project, such as the change of parameters such as the covering height and bulk density, and the spacing and size of the retaining walls are adjusted. The pebble drainage ditch 2 is arranged along the reinforced concrete retaining wall 1, and multiple groups are arranged in parallel to form a drainage network, which is conducive to drainage while keeping the planting soil moist. A drainage ditch is arranged at the bottom for organized drainage, such as Figure 3 The figure shows the construction schematic diagram of the overlap between the built-in steel bars of the reinforced concrete retaining wall 1 and the steep roof structure slab. The steel bars are anchored in the steep roof structure slab, and the reinforcement and concrete grades are in accordance with the engineering design requirements.

[0037] like Figure 1 As shown, the anti-skid structure of the steep slope planting roof is provided with an L-shaped steel plate 3. The length of the L-shaped steel plate 3 is the same as the length after the waterproof protective layer of the reinforced concrete retaining wall 1 is completed. The height perpendicular to the edge of the steep slope roof panel is the same as the length parallel to the edge of the steep slope roof panel, both of which are equal to the elevation difference of 10mm from the elevation of the waterproof protective layer of the steep slope roof panel to the elevation below the finished surface of the planting soil layer 10. The inner corner of the L-shaped steel plate 3 is set to be 200mm wide, and the area above the drainage board of the steep slope roof panel to the height range between the waterproof protective layer of the retaining wall is filled with pebbles as a drainage ditch 2.

[0038] like Figure 4-13As shown, the anti-skid structure of the large slope planting roof is provided with an anti-skid component 16, the anti-skid component 16 is provided with an anti-skid grid component 14 and a connecting member 15, the anti-skid grid component 14 is provided with an anti-skid grid 17 and a tie belt 18, the planting soil layer 10 between the reinforced concrete retaining wall 1 along the slope is fully covered with an anti-skid grid 17, the lower end of the anti-skid grid 17 is against the L-shaped steel plate 3, the anti-skid grid 17 is provided in a rhombus or square shape, and the rhombus or square anti-skid grid 17 is provided in a height of 300 mm, and the anti-skid grid 17 is provided in accordance with the reinforced concrete retaining wall 1. A suitable number of net distances between walls 1 are selected, and the walls are arranged in groups. A flat steel tie belt 18 is set in the middle of the anti-slip grid 17 in the slope direction. When the tie belt 18 is set to the pebble drainage ditch 2, the tie belt 18 is appropriately raised in the direction perpendicular to the large slope roof panel to avoid the pebble drainage ditch 2; the connection member 15 is set in the form of a gate-shaped member 19, a cable 20 and a pre-buried joint 22. Different methods are selected to install the connection member 15 according to the installation requirements of the project site. The gate-shaped member 19 is made of angle steel welding. The gate-shaped member 19 is set The door-shaped member 19 is arranged to be aligned with the tie strap 18 of the anti-skid component 16. The door-shaped member 19 is a detachable type, which is convenient for installation and removal. The L-shaped steel plate 3 at the location where the door-shaped member 19 is set is grooved; when the cable 20 is set, the pull ring 21 needs to be embedded in the reinforced concrete retaining wall 1; when the embedded joint 22 is used, it is made of angle steel or flat steel, and is arranged perpendicular to the direction of the large slope roof panel in the middle of the finished surface of the reinforced concrete retaining wall 1 structure and the waterproof protective layer of the large slope panel; after the construction is completed, the downward force of the planting soil layer along the slope is transmitted to the anti-skid grid 17 , the anti-skid grid 17 transmits the force to the L-shaped steel plate 3, and the L-shaped steel plate 3 transmits the force to the reinforced concrete retaining wall 1; the downward force of the building method above the large slope roof panel is transmitted to the reinforced concrete retaining wall; finally, the reinforced concrete retaining wall 1 transmits the force to the large slope roof panel, thereby enhancing the overall anti-slip ability of the entire planting roof; at the same time, the pebble drainage ditch 2 at the inner corner of the L-shaped steel plate 3 can not only play a role in drainage, but also allow the L-shaped steel plate 3 and the reinforced concrete retaining wall 1 to effectively transmit force, and can also prevent the L-shaped steel plate 3 from overturning and meet a higher planting soil height; such as Figure 4 The anti-skid grid 17 shown is of diamond-shaped structure, and the inner angles of the diamond-shaped anti-skid grid 17 are all 90°, or can be adjusted according to the net distance between retaining walls and engineering needs; the diamond-shaped anti-skid grid is conventionally set at 900mm in diagonal length and 300mm in height, conventionally formed into a group of 9 pieces, arranged in 3×3, and a flat steel tie belt 18 is set in the middle of the anti-skid grid 17 in the slope direction.

[0039] like Figure 5As shown, if the tie band 18 is set at the pebble drainage ditch 2, the tie band 18 can be appropriately raised in the direction perpendicular to the roof panel to avoid the pebble drainage ditch 2. The overlapping part of the anti-skid grid 17 and the pebble drainage ditch 2 is cut off to avoid affecting the drainage; when the connecting member 15 is a gate-shaped member 19, it is made of angle steel, and the angle steel is connected by welding. If bolt connection is adopted, bolt welding connection is required to reduce the deformation of the gate-shaped member 19 during use. The size of the gate-shaped member 19 is made according to the size that can be tightly buckled on the reinforced concrete retaining wall 1 after the construction is completed. The gate-shaped member 19 is set at a position aligned with the tie band 18 of the anti-skid component 14.

[0040] like Figure 6-7 As shown, when the connecting member 15 adopts a cable 20, a pull ring 21 needs to be embedded in the reinforced concrete retaining wall 1, one end of the cable 20 is connected to the pull ring 21, and the other end is connected to the anti-slip grid component 14; the pull ring 21 is arranged on the reinforced concrete retaining wall 1 along the slope direction and is aligned with the tie belt 18 of the anti-slip component 14, and the pull ring 21 is arranged perpendicular to the direction of the steep roof panel at the middle position between the structural finished surface of the reinforced concrete retaining wall 1 and the waterproof protective layer of the steep roof panel; the pull ring 21 needs to protrude from the construction practice finished surface of the reinforced concrete retaining wall 1 by a certain height and meet the tie requirements of the cable 20. The arc diameter of the pull ring 21 protruding from the construction practice finished surface of the reinforced concrete retaining wall 1 is generally 100 mm.

[0041] like Figure 8-9 As shown, the pull ring 21 can also be set on the bottom side of the slope of the reinforced concrete retaining wall 1. The advantage of this method is that it avoids the damage of the construction layer of the reinforced concrete retaining wall 1 by the cable 20, and there is no need to groove the L-shaped steel plate 3. The disadvantage is that the embedded position of the pull ring 21 is prone to leakage when pouring concrete, affecting the quality of the reinforced concrete retaining wall. The pull ring 21 is made of round steel, and the specifications are determined according to the engineering design. It can also be embedded in the finished product. It is recommended to use a steel bar model that is easy to obtain on site while meeting the design requirements.

[0042] like Figure 10-11 As shown, when the connecting member 15 adopts the embedded joint 22, the embedded joint 22 is made of angle steel or flat steel, and the embedded joint 22 is arranged on the bottom side of the slope of the reinforced concrete retaining wall 1. The setting requirements are the same as those of the pull ring 21. Compared with the door-shaped connecting member 19 and the cable 20 connecting member, this method has the advantages of saving materials and no need to groove the L-shaped steel plate 3. The disadvantage is that the embedded position is prone to leakage during concrete pouring, which affects the quality of the reinforced concrete retaining wall.

[0043] The connection method between the connecting member 15 and the anti-skid component 14 in the anti-skid structure of the steep planting roof shown is a weld connection. The thinnest part of the planting soil layer 10 is not less than 400mm above the finished surface of the waterproof protective layer on the top of the reinforced concrete retaining wall 1, which meets most landscape greening planting requirements. Construction workers will not step on the anti-skid grid when standing in the anti-skid grid, reducing damage to the anti-skid grid and construction safety hazards. Compared with the existing construction technology, it solves the problems of difficulty in waterproof construction, increased safety hazards in construction operations, and reduced waterproof quality caused by the connecting members pre-buried in the structural layer of the existing steep planting roof nodes; solves the problem that the connecting members pre-buried in the waterproof protective layer are prone to tearing the waterproof protective layer during use, thereby reducing the anti-slip effect and waterproof effect; solves the problem of using a large amount of steel in the existing node method; and solves the problem of poor drainage at the concrete retaining wall position.

[0044] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any modification or equivalent change made based on the technical essence of the present invention still falls within the scope of protection required by the present invention.
