Description

Technical Field

[0001] The present invention relates to the technical field of building doors and windows, and in particular to a cantilever awning and an installation method thereof. Background Art

[0002] An awning is a building assembly provided above the entrance or top balcony of a building to shield from rain and wind and protect the outer door from rain erosion. According to its scale and structure, it can be divided into three forms: 1. Small awning, such as cantilever awning and suspended awning; 2. Large awning, such as wall or column supported awning; 3. New assembled awning.

[0003] Among them, for a cantilever awning, the main beam of the steel structure keel is first welded and fixed to the wall embedded parts, then the secondary beam of the steel structure keel is welded to the main beam, and finally the panel is laid and fixed on the steel structure keel. Through long-term use practice, we found that the current cantilever awnings generally have the following problems:

[0004] 1. The end of the main beam is welded to the embedded parts. When the cantilever awning is too large, other strengthening measures such as tie rods need to be appropriately increased, which requires on-site welding. The on-site welding is difficult, and the weld quality cannot be effectively guaranteed; at the same time, the construction period of the awning is slow.

[0005] 2. It is often necessary to set up a scaffold outside the main structure to install the steel structure keel, which is time-consuming and laborious. And in some projects, due to site restrictions, it is impossible to set up a scaffold, resulting in the inability to implement the cantilever awning of the above structure, and it is difficult to promote.

[0006] 3. The levelness of the steel structure keel cannot be guaranteed during on-site welding and fabrication, resulting in unevenness of each panel on the steel structure keel, insufficient flatness, and easy to cause serious local water accumulation. Summary of the Invention

[0007] The purpose of the present invention is to provide a cantilever awning with fast assembly and good flatness and an installation method thereof in view of the deficiencies of the prior art.

[0008] The cantilever awning provided by the present invention includes a steel structure keel installed on wall embedded parts. The wall embedded parts include main embedded parts and auxiliary embedded parts arranged below the main embedded parts. A main ear plate and an auxiliary ear plate extending out of the wall are fixedly connected to the main embedded parts and the auxiliary embedded parts respectively. The steel structure keel is formed by inserting and connecting a number of keel units arranged in sequence in the left - right direction along the wall. The keel unit includes a front beam, a number of main beams vertically welded to the rear side of the front beam, a number of secondary beams vertically welded to the main beams, and a number of struts vertically welded to the bottom of the front beam. The rear end of the main beam bends upward and is detachably connected to the main ear plate on the main embedded part, and the rear end of the strut bends downward and is detachably connected to the auxiliary ear plate on the auxiliary embedded part. A sleeve core with adjustable up - and - down position is detachably connected to the end of the front beam and is used for inserting and connecting with the front beam in the adjacent keel unit.

[0009] To further increase the bearing strength, the main beam and the strut are arranged in a one - to - one corresponding up - and - down manner on the front beam.

[0010] To further increase the bearing strength, the keel unit further includes a number of reinforcing bars vertically welded between adjacent struts.

[0011] To further reduce the horizontal error, an insert core for inserting and connecting with the secondary beam in the adjacent keel unit is welded on one side of the main beam.

[0012] To further improve the drainage performance, a cantilever beam is vertically welded on the front side of the front beam, and a steel through - pipe parallel to the front beam is welded at the front end of the cantilever beam. A drainage trough is installed in the area surrounded by the front beam, the cantilever beam and the steel through - pipe.

[0013] To further reduce the installation difficulty caused by construction errors, a first long hole arranged vertically is opened at one end of the sleeve core. The sleeve core is detachably connected to the end of the front beam through a bolt connection assembly passing through the first long hole, and the up - and - down position of the sleeve core on the front beam is adjusted through the first long hole.

[0014] To further reduce the installation difficulty caused by construction errors, a second long hole arranged vertically is opened on the auxiliary ear plate. The auxiliary ear plate is detachably connected to the rear end of the strut through a stainless - steel pin shaft passing through the second long hole, and the up - and - down position of the strut on the auxiliary ear plate is adjusted through the second long hole.

[0015] The installation method of the present invention for the cantilever awning includes the following steps:

[0016] S1. According to the size of the panel in the cantilever awning, divide the steel structure keel into n keel units in the left - right direction along the wall, where n is a positive integer; design and determine the manufacturing parameters of the main beam and the strut in the keel unit according to the horizontal distance between adjacent main embedded parts and the vertical distance between the upper - lower adjacent main embedded parts and auxiliary embedded parts.

[0017] S2. According to the manufacturing parameters in step S1, process or prepare the keel units in the factory;

[0018] S3. Determine the installation sequence of the keel units in the left-to-right or right-to-left manner. Stack the corresponding keel units on the lift from top to bottom according to this installation sequence, and lift the keel units and the panel to the installation position through the lift;

[0019] S4. Fix the first keel unit to the corresponding main embedment and secondary embedment through the bolt connection assembly;

[0020] S5. Assemble the corresponding panels on the first keel unit in sequence from top to bottom or from bottom to top;

[0021] S6. Move the second keel unit to the installation position through the lift, horizontally push the second keel unit, so that the second keel unit is inserted and connected to the first keel unit, adjust the left and right positions of the second keel unit to ensure that the second keel unit is butted left and right with the corresponding main embedment and secondary embedment, and fix and connect the second keel unit to the corresponding main embedment and secondary embedment through the bolt connection assembly;

[0022] S7. Assemble the corresponding panels on the second keel unit in sequence according to the method in step S5;

[0023] S8. Repeat steps S6 and S7 to complete the installation of all keel units and panels;

[0024] S9. Set foam rods and sealant between adjacent panels and between the panel and the wall surface.

[0025] In the above step S9, the setting of the foam rod needs to be carried out on cloudy or sunny days when the temperature is between 5°C and 35°C.

[0026] In the above step S2, the keel units processed in the factory need to be inspected first, and large-scale processing and production can be carried out after passing the inspection requirements.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. Decompose the steel structure keel into several keel units, which is convenient for the keel units to be processed and completed in the factory, helps to realize factoryization, can not only reduce the workload of on-site welding construction, speed up the construction speed, but also reduce the errors brought by on-site welding construction, further ensure the flatness of the steel structure keel, and is beneficial to the unity after the panel is laid.

[0029] 2. Use the insertion connection method to complete the assembly between the keel units, with fewer welding places at the construction site, which can not only avoid the difficulty brought by welding construction, but also avoid the insecurity brought by welding construction, and is more environmentally friendly.

[0030] 3. Applying an upward supporting force to the front-end beam and the main beam using a support pole can effectively reduce the reaction force on the main embedded parts, resulting in better safety.

[0031] 4. The main beam adopts a form that bends upward at the rear end, and the panel will be arranged obliquely on the main beam. Under the guiding action of the panel, rainwater will be guided outside the canopy, thereby reducing the occurrence of water accumulation and facilitating the elimination of rainwater penetration at the joint of the panel.

[0032] The present invention can further solve the problems of water accumulation and slow construction of the cantilevered canopy, and is more suitable for use in prefabricated houses. Description of the Drawings

[0044] The wall embedded parts include a main embedded part 1 and a secondary embedded part 2 arranged below the main embedded part 1. A hot-dip galvanized steel pipe extending out of the wall is vertically welded on the main embedded part 1, and a main ear plate 11 is welded at the bottom of the hot-dip galvanized steel pipe; a steel pipe extending out of the wall is vertically welded on the secondary embedded part 2, and a secondary ear plate 21 is welded at the front end of the steel pipe. A vertically arranged second long hole 211 is opened on the secondary ear plate 21;

[0045] The steel structure keel includes a number of keel units 3. Each keel unit 3 includes a front-end beam 31, a main beam 32, a secondary beam 33, a strut 34 and a sleeve core 35. There are at least two main beams 32. Each main beam 32 is bent with the front end lower and the rear end higher. The front end of each main beam 32 is perpendicularly welded and connected to the rear end face of the front-end beam 31. The rear end of each main beam 32 is detachably connected to the main ear plate 11 on the corresponding main embedded part 1 through a stainless steel pin shaft. The main beams 32 are evenly distributed on the front-end beam 31;

[0046] There are at least two secondary beams 33. Each secondary beam 33 is perpendicularly welded between adjacent main beams 32. The secondary beams 33 are evenly distributed on the main beams 32;

[0047] There are at least two struts 34. Each strut 34 is bent with the front end higher and the rear end lower. The front end of each strut 34 is perpendicularly welded and connected to the bottom of the front-end beam 31. The rear end of each strut 34 is detachably connected to the secondary ear plate 21 on the corresponding secondary embedded part 2 through a stainless steel pin shaft passing through the second long hole 211. The strut 34 is adjusted up and down on the secondary ear plate 21 through the second long hole 211;

Vertically arranged first long holes 351 are penetrated on the front and rear side surfaces of the sleeve core 35 inside the front-end beam 31. The sleeve core 35 is detachably connected to the end of the front-end beam 31 through a bolt connection assembly passing through the first long holes 351. The sleeve core 35 is adjusted up and down on the front-end beam 31 through the first long holes 351;

[0050] Each keel unit 3 is sequentially connected in the left-right direction of the wall to the corresponding main embedded part 1 and secondary embedded part 2.

The insertion core 37 is coaxially arranged with the secondary beam 33 in the adjacent keel unit 3 on the right. The outer diameter of the insertion core 37 is smaller than the inner diameter of the secondary beam 33 in the adjacent keel unit 3 on the right. The vertical positions of the main beam 32 and the secondary beam 33 in two adjacent left and right keel units 3 are defined by the insertion core 37.
