Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a ground-mounted scaffolding support device at an overhanging eaves. Background Art

[0002] During the construction of building structures, eaves are often added near the ground on the first floor of the building. When constructing the upper part of the eaves, scaffolding needs to be set up above the eaves. At this time, the eaves are required to have sufficient bearing capacity to effectively support the upper scaffolding.

[0003] In order to improve the bearing capacity of the eaves, the conventional practice is to lay gray sand bricks under the eaves and fill the gaps in the eaves with templates. However, since the eaves are too close to the outdoor floor and the operating space is small, it is difficult to operate during construction and the construction progress is slow. Therefore, this method has certain limitations. In response to the above problems, some construction sites set up reserved holes on the eaves so that the scaffolding can penetrate the eaves and support the outdoor floor. However, this method requires thick cutting to fill the reserved holes on the eaves with a higher grade of concrete, and there are many filling areas, which is relatively costly. In addition, before setting up the scaffolding, this method requires waterproofing the foundation and installing insulation boards, and then backfilling the soil. The scaffolding must be set up after the backfill is completed and the cushion layer is poured, so the construction requirements are relatively high.

[0004] Based on the above problems, a ground-mounted scaffolding support device for the overhanging eaves is proposed. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a support device for ground scaffolding at the eaves, so as to achieve the technical effect of effectively transferring the load of the ground scaffolding to the ground and reasonably protecting the completed eaves.

[0006] To achieve this technical purpose, the present invention adopts the following scheme:

[0007] A ground scaffolding support device at an overhanging eave comprises an overhanging eave and a support body. The support body comprises a support screw and a support sleeve. The support screw is threadedly connected to the support sleeve, and the support sleeve is in close contact with the lower surface of the overhanging eave.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The present invention provides effective support below the eaves, can effectively transfer the scaffolding load to the ground, and at the same time does not require opening holes in the eaves and subsequent filling of the holes, effectively protects the roots of the eaves, reduces the load borne by the eaves, and reasonably protects the completed eaves.

[0010] Furthermore, the preferred embodiment of the present invention is:

[0011] An adjustment handle is located in the middle of the support screw, with threads on both ends of the handle facing in opposite directions. Each thread segment on the support screw is connected to a corresponding support sleeve. By using the principle of two oppositely threaded segments, the two support sleeves can move independently.

[0012] The two supporting sleeves include an upper supporting sleeve and a lower supporting sleeve. An upper pad is provided on the top of the upper supporting sleeve, and a lower pad is provided on the bottom of the lower supporting sleeve.

[0013] Positioning steel bars are reserved at the center of the upper scaffolding column of the eaves. The positioning steel bars pass through the eaves and both ends of the positioning steel bars extend to the outside of the eaves. A lower positioning hole is opened at the center of the upper support sleeve corresponding to the upper pad, and the lower part of the positioning steel bar is plugged into the lower positioning hole.

[0014] A positioning pad is provided at the bottom of the upper scaffolding column. A through hole is opened on the positioning pad corresponding to the center position of the column, and the through hole is plugged into the upper end of the positioning steel bar.

[0015] The upper scaffolding of the cantilever is aligned with the device up and down to ensure that the load is effectively transferred to the ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments, but the present invention is not limited thereto.

[0019] A ground scaffolding support device at an overhanging eaves, such as Figure 1 As shown, it consists of an overhanging eaves 1 and a supporting body. An upper scaffolding is set up above the overhanging eaves 1, and the supporting body is set below.

[0020] The support body consists of a support screw 4 and a support sleeve. An adjustment handle 10 is provided in the middle of the support screw 4. The threads of the support screw 4 at both ends of the adjustment handle 10 are set in reverse. A support sleeve is threadedly connected to each thread position on the support screw 4.

[0021] In this embodiment, the two support sleeves are an upper support sleeve 5 and a lower support sleeve 6. An upper pad 7 is provided on the top of the upper support sleeve 5, and a lower pad 8 is provided on the top of the lower support sleeve 6. When installed in place, the upper pad 7 is in close contact with the lower surface of the eaves 1, and the lower pad 8 is in close contact with the surface of the outdoor floor.

[0022] A positioning steel bar 3 is reserved at the center position of the eaves 1 corresponding to the upper scaffolding column 2. The positioning steel bar 3 passes through the eaves 1 and both ends of the positioning steel bar 3 extend to the outside of the eaves 1. A positioning hole is opened at the center position of the upper pad 7 corresponding to the upper support sleeve 5, and the lower part of the positioning steel bar 3 is plugged into the positioning hole.

[0023] The bottom of the upper scaffolding column 2 is also fixedly connected with a positioning pad 9, and the positioning pad 9 has a through hole corresponding to the center position of the column, and the through hole is plugged with the upper end of the positioning steel bar 3.

[0024] Before tying up the upper scaffolding of the eaves 1, follow the construction process of the eaves 1: erect the buckle scaffolding - support the template at the eaves 1 - measure and lay out the position of the ground scaffolding and mark it with paint on the eaves 1 template - tie the steel bars at the corresponding eaves 1 position, and reserve positioning steel bars 3 at the corresponding installation position of the ground scaffolding columns when tying - pour concrete - remove the template - install this support device under the eaves 1.

[0025] When installing this support device, place the entire device under the eaves 1, first hold the upper support sleeve 5 with your hand, then turn the adjusting wrench to rotate the support screw 4 and the lower support sleeve 6. When the upper support sleeve 5 is rotated to a certain distance, insert the upper pad 7 into the positioning steel bar 3 and the upper pad 7 contacts the lower surface of the eaves 1, then adjust the lower support sleeve 6 downward until the lower support sleeve 6 contacts the outdoor floor (ground).

[0026] When adjusting this device, you only need to manually tighten it to ensure the load transfer of the upper scaffolding. Do not allow this device to over-reinforce the eaves 1, otherwise it will generate a downward force on the eaves 1 and damage the eaves 1.

[0027] In this embodiment, when pre-embedding the positioning steel bars 3 , the positioning steel bars 3 are attached to the original reinforcement foundation of the eaves 1 by binding and overlapping.

[0028] The apertures of the positioning holes and through holes in this device are only slightly larger than the diameter of the positioning steel bars 3. By plugging the positioning holes and through holes into the positioning steel bars 3 respectively, the upper scaffolding and the support sleeve are aligned vertically, ensuring that the load of the upper scaffolding falls to the ground.

[0029] This device can provide reasonable protection for the completed eaves, provide effective support for the scaffolding above the eaves, reduce the load borne by the eaves, reduce the cracking rate at the root of the eaves and the integrity of the eaves, improve the construction efficiency of the eaves, and this device can also be used in a turnover manner.

[0030] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art may make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered to be within the scope of protection of the present invention.
