Description

Technical Field

[0001] The invention relates to a construction method of a permanent hanging basket suspension device for a roof overhanging eaves, belonging to the field of building construction methods. Background Art

[0002] With the development of construction technology, architectural art has also developed in a diversified manner. Some modern building roofs continue to use the design techniques of ancient buildings, using overhanging roofs to make the roof shape more modern. The overhanging distance of roof eaves is getting longer and longer. The use of conventional hanging basket suspension mechanisms in the decoration and renovation of building facades and roof overhangs and later repair construction will not be able to meet construction needs. The existing technology for the hanging basket suspension mechanism of cast-in-place roof overhang design is temporary. After the construction is completed, the hanging basket cantilever mechanism is dismantled and there is no permanent fixing measure. Later, when the exterior decoration of the building is repaired, the hanging basket suspension mechanism needs to be reinstalled, which increases maintenance costs. In many projects, the suspension mechanism cannot be installed in the later stage, and the hanging basket cannot be used for repair.

[0003] Patent 202010958939.4: A method and installation structure for vertically installing a hanging basket for the construction of an external cantilever gutter on a sloping roof. The cantilever structure is weak in design. Installing a hanging basket suspension mechanism at the cantilever position will cause the cantilever structure itself to fail to meet the bearing capacity requirements. This can easily cause structural cracks at the base of the cantilever structure due to the use of the hanging basket, affecting the safety of the cantilever structure. Moreover, the structural reinforcement measures are temporary. After use, the hanging basket needs to be removed before the upper part of the cantilever can be decorated.

[0004] Patent 202220420900.1: A fixing structure for installing a hanging basket on a sloping roof with overhanging eaves. The hanging mechanism is directly anchored to the roof overhanging eaves structure. Because the anchor bolts and the overhanging eaves structure are fixed with structural adhesive, the hanging basket is subject to vibration loads during use. Under the repeated action of vibration loads, the anchor bolts and the overhanging eaves structure fixing adhesive are easily separated and fail, leading to safety accidents.

[0005] Patent 202122714559.9: A hanging basket suspension device for curtain wall construction. For cantilevered eaves structures with excessive roof cantilevering distances, in order to reduce the deadweight of the concrete structure and ensure the overall design of the roof structure, the design rarely uses solid structures with larger cross-sectional dimensions. This patent is not applicable to cantilevered eaves structures with excessive roof cantilevering distances, so the versatility of this patent is limited. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: to propose a construction method for a permanent hanging basket suspension device for roof eaves. The permanent hanging basket suspension device for roof eaves constructed using this construction method can not only ensure the construction work requirements and safety, but also meet the needs of building facades and roof overhangs under larger overhanging roofs for decoration and later repair construction.

[0007] The construction method of the permanent hanging basket suspension device for roof eaves of the present invention specifically comprises the following steps:

[0008] Step 1: Build the main structure of the eaves and parapet frame, determine the installation position of the hanging basket ring on the main structure of the frame, and install the eaves positioning sleeve and wall positioning sleeve on the main structure of the eaves and parapet frame; the eaves include a horizontal eaves and an inclined support body, and the horizontal eaves, inclined support body and parapet form a triangular structure;

[0009] Step 2: integrally casting the eaves and parapet frame with the building exterior wall;

[0010] Step 3: Make hanging rings;

[0011] Step 4: Insert the vertical tail of the lifting ring into the eaves positioning sleeve and pass it through the top of the inclined support body of the eaves, and the annular head of the lifting ring is stuck under the horizontal eaves; the vertical tail of the lifting ring passes through the backing plate 1 set on the inclined support body, and then is locked and fixed with the locking piece 1;

[0012] Step 5: Place the closed end of the U-shaped frame over the top of the vertical tail of the lifting ring, and secure the closed end of the U-shaped frame to the first pad. Pass the open end of the U-shaped frame through the wall positioning sleeve and secure it to the second locking piece.

[0013] Step 6: Use the construction scaffolding to complete the installation and reservation of the hanging basket wire rope;

[0014] Step 3 is not limited to being performed after step 1 and step 2.

[0015] After the completion of step 2, it is necessary to test the strength of the main structure concrete to 100% of the design strength before the hanging ring can be installed; the horizontal overhanging eaves, the inclined support body and the parapet at the top of the building's outer wall form a hollow triangular stable structure with light weight and strong bearing capacity, which can avoid the hidden dangers of structural cracks in the overhanging eaves structure caused by the use of the hanging basket, which affects the structural quality; the hanging ring includes a ring head and a vertical tail, and its vertical tail part passes through the pad 1; the locking piece 1 is fixed to the vertical tail of the hanging ring by a threaded connection and then spot welded, and the locking piece 2 is fixed to the open end of the U-shaped frame by a threaded connection and then spot welded. The roof overhanging eaves permanent hanging basket suspension device obtained by applying this construction method has high stability and safety, can meet the needs and safety of construction operations, and does not need to be dismantled after construction is completed, will not affect other construction, and can meet the requirements of the cast-in-place roof overhanging eaves permanent hanging basket suspension for the building facade under the larger overhanging roof and the roof overhanging shape decoration and later repair construction.

[0016] Preferably, in the process of making the hanging ring in step three, the whole galvanized round steel is bent into shape to form a ring-shaped head, and the vertical ends on both sides of the ring-shaped head form an overlapping section, which is fixed by welding.

[0017] Preferably, the overlap length is greater than or equal to 200 mm. During use, the galvanized round steel lifting ring will not be damaged under vibration loads and construction loads. The vertical tail end of the lifting ring is threadedly connected to the locking piece and then fixed by spot welding.

[0018] Preferably, a wedge block is added between the locking member 1 and the backing plate 1, and the wedge block is welded and fixed to the backing plate 1 and the locking member 1 respectively. The vertical tail of the lifting ring passes through the wedge block. Before welding, the locking member 1 is tightened first to stabilize the relative positions of the components, and then welding is performed to prevent the locking member 1 from loosening later. Since the inclined support body is inclined, and the vertical tail of the lifting ring vertically passes through the inclined support body, there will still be a gap between the locking member 1 and the backing plate 1 after the locking member 1 is threadedly connected and tightened with the vertical tail. The wedge block compensates for this gap, making the cooperation between the locking member 1 and the vertical tail and the backing plate 1 more reliable. The wedge block is welded and fixed to the backing plate 1 and the locking member 1 respectively.

[0019] Preferably, the U-shaped frame is a U-shaped galvanized round steel, and the diameter of the U-shaped galvanized round steel is greater than 16 mm.

[0020] Preferably, the open end of the U-shaped frame passes vertically through the parapet, ensuring that the U-shaped frame is perpendicular to the second pad and the parapet, and there is no gap caused by tilt between the second pad and the parapet. After the bolts are connected, the components are tightly connected and the stress condition is best.

[0021] Preferably, the arc-shaped closed end of the U-shaped galvanized round steel is welded to the backing plate, and the welding overlap length is preferably 200mm-250mm. The U-shaped galvanized round steel and the backing plate are welded and fixed stably and reliably.

[0022] Preferably, a decorative layer is provided on the top surface of the inclined support body, and the permanent hanging basket suspension device of the roof eaves completed according to this construction method does not need to be dismantled, which will not affect the subsequent decoration and the overall appearance of the building.

[0023] Preferably, before providing the decorative layer, a leveling layer is first constructed to cover the vertical tail of the lifting ring, the first locking piece, the first pad and the U-shaped frame.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] By applying the construction scheme of the present invention, the horizontal overhanging eaves, the inclined support body and the parapet at the top of the outer wall of the building form a hollow triangular stable structure with light dead weight and strong bearing capacity, which can avoid the hidden dangers of structural cracks in the overhanging eaves structure caused by the use of the hanging basket, which affect the structural quality; the whole set of equipment has high stability and safety, can ensure the construction work needs and safety, and does not need to be dismantled after the construction is completed, and will not affect other construction. It can meet the needs of permanent hanging basket suspension of cast-in-place roof overhanging eaves for building facades and roof overhanging decoration and later repair construction under larger overhanging roofs; the hanging basket can be directly hung in later repair construction without damaging the roof decorative layer.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figure 1-Figure 3 The construction method of the permanent hanging basket suspension device for roof eaves of the present invention specifically includes the following steps:

[0032] Step 1: Build the main frame structure of the eaves and parapet 2, determine the installation position of the hanging basket ring 11 on the main frame structure, and install the eaves positioning sleeve and wall positioning sleeve on the main frame structure of the eaves and parapet 2; the eaves include a horizontal eaves 10 and an inclined support body 9, and the horizontal eaves 10, the inclined support body 9 and the parapet 2 form a triangular structure;

[0033] Step 2: integrally casting the eaves and parapet 2 frames with the building exterior wall 1;

[0034] Step 3, making a hanging ring 11;

[0035] Step 4: Insert the vertical tail 14 of the lifting ring 11 into the eaves positioning sleeve and pass it through the top of the inclined support body 9 of the eaves. The annular head 15 of the lifting ring 11 is stuck under the horizontal eaves 10. The vertical tail 14 of the lifting ring 11 passes through the backing plate 8 set on the inclined support body 9 and is then locked and fixed with the locking piece 6.

[0036] Step 5: Place the closed end of the U-shaped frame 5 over the top of the vertical tail 14 of the lifting ring 11, and securely connect the closed end of the U-shaped frame 5 to the backing plate 1 8. Pass the open end of the U-shaped frame 5 through the wall positioning sleeve and secure it to the locking piece 2 3.

[0037] Step 6: Use the construction scaffolding to complete the installation and reservation of the hanging basket wire rope 12;

[0038] Step 3 is not limited to being performed after step 1 and step 2.

[0039] In this embodiment:

[0040] Step 3 is the process of making the suspension ring 11. The whole galvanized round steel is bent into shape to form a ring head 15. The vertical ends on both sides of the ring head 15 form a lap section 16, and the lap section 16 is fixed by welding.

[0041] The length of the overlap section 16 is greater than or equal to 200mm. During the use of the hanging basket 13, the galvanized round steel lifting ring 11 will not be damaged under the action of vibration load and construction load. The vertical tail thread of the lifting ring 11 is first threadedly connected to the locking piece 6 and then fixed by spot welding.

[0042] A wedge block 7 is added between locking piece 6 and pad 8, and is welded to pad 8 and locking piece 6, respectively. The vertical tail 14 of the lifting ring 11 passes through the wedge block 7. Before welding, tighten locking piece 6 to stabilize the relative positions of the components. Then, weld to prevent locking piece 6 from loosening later. Because the inclined support body 9 is inclined and the vertical tail 14 of the lifting ring 11 vertically passes through the inclined support body 9, a gap still exists between locking piece 6 and pad 8 after the locking piece 6 and the vertical tail 14 are threaded and tightened. The wedge block 7 compensates for this gap, ensuring a more secure fit between the locking piece 6, the vertical tail 14, and pad 8. The wedge block 7 is welded to pad 8 and locking piece 6, respectively.

[0043] The U-shaped frame 5 is a U-shaped galvanized round steel, and the diameter of the U-shaped galvanized round steel is greater than 16 mm.

[0044] The open end of the U-shaped frame 5 passes vertically through the parapet 2, ensuring that the U-shaped frame 5 is perpendicular to the pad 2 4 and the parapet 2, and there is no gap caused by tilt between the pad 2 4 and the parapet 2. After the bolts are connected, the various components are tightly connected and the stress condition is best.

[0045] The arc-shaped closed end of the U-shaped galvanized round steel is welded and fixed to the pad 8, and the welding overlap length should be 200mm-250mm. The welding and fixing of the U-shaped galvanized round steel and the pad 8 are stable and reliable.

[0046] A decorative layer 17 is provided on the top surface of the inclined support body 9. The permanent hanging basket suspension device of the roof eaves completed according to this construction method does not need to be removed, which will not affect the later decoration and the overall beauty of the building.

[0047] Before setting the decorative layer 17 , a leveling layer is first constructed to cover the vertical tail 14 of the lifting ring 11 , the locking piece 6 , the pad 8 and the U-shaped frame 5 .

[0048] After the completion of step 2, the main structure concrete strength needs to be tested to ensure that it reaches 100% of the design strength before the hanging ring 11 can be installed. The horizontal eaves 10, the inclined support body 9 and the parapet 2 at the top of the building's outer wall 1 form a hollow triangular stable structure with light weight and strong bearing capacity, which can avoid the hidden dangers of structural cracks in the eaves structure caused by the use of the hanging basket 13, which affect the structural quality. The hanging ring 11 includes a circular head 15 and a vertical tail 14, and its vertical tail 14 part passes through the pad 1 8. The locking piece 1 6 is fixed to the vertical tail 14 of the hanging ring 11 by threading and then spot welded, and the locking piece 2 3 is fixed to the open end of the U-shaped frame 5 by threading and then spot welded. The roof eaves permanent hanging basket suspension device obtained by applying this construction method has high stability and safety, can meet the needs and safety of construction work, and does not need to be dismantled after construction is completed, which will not affect other construction. It can meet the needs of permanent hanging basket suspension of cast-in-place roof eaves for building facades under large overhanging roofs and roof overhanging decoration and later repair construction. A backing plate 4 is provided between the second locking member 3 and the parapet 2 .

[0049] Both the backing plate 1 8 and the backing plate 2 4 can be made of steel plates. The backing plate 1 8 can be made of 150×300×10mm steel plates, and the backing plate 2 4 can be made of 100×200×10mm steel plates. The U-shaped frame 5 and the backing plate 1 8 are fully welded around, and the weld height is not less than 6mm.

[0050] A permanent hanging basket suspension device for the roof eaves is arranged at the top of the building's outer wall 1, and includes a horizontal eaves 10, an inclined support body 9 and a hanging ring 11. The horizontal eaves 10, the inclined support body 9 and the parapet 2 at the top of the building's outer wall 1 form a triangular structure; the annular head 15 of the hanging ring 11 is located below the horizontal eaves 10, and the vertical tail 14 of the hanging ring 11 passes through the horizontal eaves 10 and the inclined support body 9, and is locked and fixed with a locking piece 6 above the inclined support body 9. A pad 8 is provided between the locking piece 6 and the top surface of the inclined support body 9. The pad 8 is fixedly connected to the closed end of the U-shaped frame 5, and the open end of the U-shaped frame 5 passes through the parapet 2 from one side and is fixedly connected to the locking piece 2 3 on the other side of the parapet 2.

[0051] The lifting ring 11 includes a ring head 15 and a vertical tail 14, the vertical tail 14 of which is threaded and partially penetrates the pad 8; the horizontal eaves 10, the inclined support body 9 and the parapet 2 at the top of the outer wall 1 of the building form a hollow triangular stable structure with light weight and strong bearing capacity, which can avoid the hidden dangers of structural cracks in the eaves structure due to the use of the hanging basket 13, which affect the structural quality; the pad 8 is welded to the arc-shaped closed end of the U-shaped frame 5, and the welding lap length is preferably 200mm-250mm, and the open end of the U-shaped frame 5 vertically penetrates the parapet 2; the locking piece 16 is fixed to the vertical tail 14 of the lifting ring 11 by threaded connection and then spot welded, and the locking piece 2 3 is fixed to the open end of the U-shaped frame 5 by threaded connection and then spot welded. The entire system offers high stability and safety, ensuring the safety and reliability of construction operations. It does not need to be dismantled after completion, nor does it affect other construction projects. It can be used to permanently suspend cast-in-place roof overhangs, such as for exterior facade and roof overhangs, decorative decoration, and subsequent renovation work under large overhanging roofs. The lifting ring 11 and U-shaped frame 5 are secured together by an anchor plate. The tension exerted on the lifting ring 11 is transferred to the shear wall through the U-shaped frame 5, effectively reducing the tension on the overhang and significantly preventing cracks in the overhang due to insufficient tensile strength.

[0052] A pad 2 4 is provided between the locking member 2 3 and the parapet 2, and the open end rod of the U-shaped frame 5 passes through the pad 2 4. The functions of the pad 2 4 and the pad 1 8 respectively increase the force-bearing area of the locking member 2 3 and the locking member 1 6, and play the role of an ordinary gasket, making the connection relationship more stable and reliable.

[0053] A wedge block 7 is added between locking piece 6 and backing plate 8. Because the inclined support body 9 is inclined and the vertical tail 14 of the lifting ring 11 vertically penetrates the inclined support body 9, there is still a gap between locking piece 6 and backing plate 8 after the locking piece 6 and the vertical tail 14 are threaded and tightened. The wedge block 7 compensates for this gap, ensuring a more secure fit between the locking piece 6, the vertical tail 14, and the backing plate 8. The wedge block 7 is welded to the backing plate 8 and locking piece 6.

[0054] The lifting ring 11 is formed by bending galvanized round steel. The vertical tail 14 above the annular head 15 has a welded lap section 16. The welded lap section 16 is longer than 200mm, and the vertical tail end is processed with a thread. The vertical tail end of the lifting ring 11 is connected and fixed with a locking piece 6. The lifting ring 11 is formed by bending a whole piece of galvanized round steel to form an annular head 15. The vertical ends on both sides of the annular head 15 form a lap section 16 at one end. The lap section 16 is fixed by welding. The welded lap length is greater than 200mm. During the use of the hanging basket 13, under the action of vibration load and construction load, the galvanized round steel lifting ring 11 will not be damaged. The vertical tail end thread of the lifting ring 11 is first threaded and fixed with the locking piece 6, and then fixed by spot welding.

[0055] The distance between the hanging ring 11 and the building's exterior wall 1 is 1 / 2 the basket width + 250mm, or the distance between the inner side of the hanging basket and the finished decorative surface of the building's exterior wall is at least 250mm. This allows for the decorative decoration and subsequent repair of the building's facade and roof overhangs under large overhanging roofs while ensuring sufficient safety and reliability. A decorative layer 17 is added to the top surface of the inclined support body 9 to conceal the vertical tail 14 of the hanging ring 11, locking member 6, pad 8, and U-shaped frame 5, providing a more aesthetically pleasing appearance. The horizontal overhang 10, inclined support body 9, the top of the building's exterior wall 1, and the parapet 2 are integrally cast, providing high safety and stability.

[0056] The locking piece 1 6 and the locking piece 2 3 can use matching nuts, and the nuts can be double nuts.
