Description

Technical Field

[0001] The present invention belongs to the field of building construction, and particularly relates to a hanging basket installation method using post-anchoring connection and installed on a cantilevered flower rack beam on the roof. Background Art

[0002] As the most commonly used equipment for exterior wall construction in the housing construction industry, hanging baskets are mainly used as tools for exterior wall decoration. However, with the development of the construction industry, the styling designs of building roof flower rack beams in more and more high-rise buildings, office buildings, etc. are complex and diverse. If conventional hanging baskets are used to construct the exterior of the flower rack beam, a large amount of materials will be used to build the operation platform, resulting in high material costs due to the long construction period. If the method of increasing the height of the rear legs is adopted, there are also certain requirements for the height. The higher the height, the worse the stability of the rear legs. Moreover, due to the counterweight occupying the roof position, the waterproofing of the roof layer cannot be completed at one time during the placement of the hanging basket. Summary of the Invention

[0003] The present invention is applicable to roofs with cantilevered flower rack beams, where hanging baskets are required for exterior wall construction and conventional hanging basket installation methods cannot be implemented. By means of post-anchoring connection of the flower rack beam, synchronous construction of the roof and the hanging basket is achieved, saving the construction period and cost.

[0004] The present invention is realized through the following technical solutions:

[0005] Each set of hanging basket anchoring brackets of the present invention consists of two brackets. Each bracket includes an upper support, a tensioning rope, front and rear hanging heads, a large beam, a front column, an adjusting rod, a turnbuckle bolt, high-strength bolts, etc., as shown in Figure 1 .

[0006] A method for post-anchoring installation of a cantilevered flower rack beam hanging basket includes the following steps:

[0007] Step 1: Complete the measurement and layout of the positions of the flower rack beam columns.

[0008] Step 2: Weld (fully weld) the front column of the hanging basket to the embedded plate, and fix the embedded plate to the flower rack beam with four M12*160 chemical bolts, as shown in Figure 2 (front view).

[0009] Step 3: Place the large beam in the groove above the front column, with the middle part coinciding with the groove and the upper support base coinciding with the groove, and fasten with two bolts, as shown in Figure 2 (side view).

[0010] Step 4: Fix the rear pull steel wire rope to the lower structural beam, and fix it with an embedded plate, an M20 turnbuckle bolt and four M10 buckles, as shown in Figure 3 .

[0011] Step 5: The tensioning rope is pulled out from the front lifting hook on the construction surface of the flower rack beam, passed through the large-eye pulley above the upper support, and pulled to the rear sling eyebolt connected to the rear hook. The tensioning rope is fastened with a wire rope clip, and then the eyebolt is tightened to completely tension it. See Figure 4 。

[0012] Step 6: The tensioning rope led out from the rear sling is bundled and installed on the flower rack beam. Both ends of the wire rope are fastened with wire rope clips respectively, and the wire rope is tightened with an M20 eyebolt.

[0013] Step 7: Adjust the distance between the two brackets so that the distance between the overhanging endpoints of the front beam is 50 - 100 mm larger than the length of the suspension platform.

[0014] Step 8: When tensioning the strengthening wire rope, make the front beam slightly upturned by 3 - 5 cm to generate prestress and improve the stiffness of the front beam.

[0015] Step 9: When installing the wire rope of the aerial work basket, the U-shaped opening of the wire rope clip is on the opposite side of the end of the wire rope and in the same direction.

[0016] Step 10: The wire rope clips should be clamped successively starting from the hoisting point, and there should be a slight arch in the wire rope between the last wire rope clip and the previous one. See Figure 5 。

[0017] Step 11: When lowering the wire rope of the hanging basket, place the wire rope freely on the floor surface, carefully draw out the rope end and slowly slide it down along the wall. After the wire rope is paid out, the entangled ropes should be carefully separated and pressed down, and the redundant wire rope on the ground should be carefully coiled and tied tightly.

[0018] Step 12: Install the suspension platform, safety lock, hoist, weight, and limit device according to the installation method of a normal standard hanging basket.

[0019] As a preferred solution of the present invention, an inspection and operation scaffold should be erected before implementing Step 1.

[0020] As a preferred solution of the present invention, the bearing capacity of the cantilever beam should be calculated and reviewed before implementing Step 2.

[0021] As a preferred solution of the present invention, after Step 4 is completed, a pull-out test of the post-anchoring embedded plate should be carried out and a qualified test report should be issued by a third party.

[0022] As a preferred solution of the present invention, after Step 12 is completed, a correlation test of the hanging basket is also required, including but not limited to conventional tests such as static load, dynamic load, eccentric load, and ultimate load.

[0023] Advantages of the present invention:

[0024] (1) It is applicable to the construction of the outer facade of the roof cantilever flower rack beam.

[0025] (2) Minimize the auxiliary support materials required for the erection of the hanging basket.

[0026] (3) The construction of the roof layer and the hanging basket construction do not affect each other.

[0027] (4) During the installation of the roof hanging basket, the installation materials do not require the cooperation of a tower crane, and the construction elevator can complete the vertical transportation.

[0028] (5) Through the present invention, not only the problem of difficult construction on the outer facade of the cantilever beam and the flower rack beam is solved, but also the requirements of the roof waterproof construction operation surface are ensured, effectively accelerating the construction efficiency.

[0029] (6) The present invention meets the environmental protection requirements under the national low-carbon background. Brief Description of the Drawings
