Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a scaffolding installation structure on a slope. Background Technology

[0002] In current scaffolding construction, the foundation materials for scaffolding are generally wooden planks or I-beam blocks, primarily used to stabilize the scaffold structure, especially for projects with slopes less than 30°. However, some projects have very steep slopes with inclination angles exceeding 30°, even reaching 70°. On such slopes, using wooden planks for scaffolding will not provide sufficient stability, potentially leading to accidents. Currently, there are no observed applications of scaffolding erection on such slopes in China.

[0003] During the construction of the pool walls of a large-scale wastewater treatment plant, our company discovered that the slope was extremely steep, reaching 70° in the steepest part. The slope was also very high, and the surface was made of concrete, making it impossible to directly build scaffolding on the slope using pads, which greatly affected the project's construction progress. Utility Model Content

[0004] This utility model provides a scaffolding installation structure on a slope that solves the above-mentioned problems. It is suitable for projects where the slope is a concrete surface or a hard soil surface with an inclination angle greater than 30°-70°. It not only solves the above problems, but also meets the requirements for scaffolding construction safety and construction quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a scaffolding installation structure on a slope, including a slope and scaffolding. The scaffolding is composed of vertical steel pipes and horizontal steel pipes. Multiple supports for installing the vertical steel pipes are cast on the slope. Each support contains four reinforcing bars, which are centrally symmetrically distributed around the vertical steel pipes. The lower ends of the reinforcing bars are inserted into the slope. The vertical steel pipes are inserted into the supports and fixedly connected to the upper ends of the four reinforcing bars by positioning reinforcing bars. They are cast and fixed on the slope together with the supports.

[0006] Preferably, the slope has holes for inserting reinforcing bars, the lower end of which is inserted into the holes and fixed with anchoring adhesive.

[0007] As a preferred option, the aperture size is 26mm and the burial depth is 20d.

[0008] Preferably, the upper ends of the reinforcing bars are all bent toward the vertical steel pipe side and are L-shaped.

[0009] Preferably, the diameter of the reinforcing bar is 22 mm.

[0010] Preferably, the four steel bars are bound with ring-shaped reinforcing bars around their perimeter.

[0011] Preferably, the support is located between two steel bars at a lower horizontal position, and its roots are reinforced with tie bars.

[0012] Preferably, a water platform is provided on the slope for placing vertical steel pipes, and the vertical steel pipes are placed vertically on the water platform.

[0013] Preferably, the support is rectangular in size, measuring 220*240.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] (1) Wide applicability: This utility model can be used to erect scaffolding on concrete surfaces with an inclination angle of 30°-70°, which can solve the adverse effects of such slopes.

[0016] (2) High safety: The support pier is made of C30 concrete and reinforced concrete with a steel bar diameter of 22, which has high compressive strength.

[0024] The present invention will be further described below.

[0025] Example: See Figures 1 to 4A scaffolding installation structure on a slope includes a slope 4 and scaffolding. The scaffolding is composed of vertical steel pipes 2 and horizontal steel pipes. Multiple supports 1 for installing the vertical steel pipes 2 are cast on the slope 4. Each support 1 contains four steel bars 11, which are centrally symmetrically distributed with respect to the vertical steel pipes 2. The lower ends of the steel bars 11 are inserted into the slope 4. The vertical steel pipes 2 are inserted into the supports 1 and are fixedly connected to the upper ends of the four steel bars 11 by positioning steel bars 5. They are cast and fixed on the slope 4 together with the supports 1. This utility model uses a support pier 1 with high structural strength as the installation structure of the scaffold, which greatly improves the safety and stability of the scaffold installation on the steep slope 4. Each support pier 1 uses four steel bars 11 inserted into the slope 4 as a connecting skeleton, which greatly improves the structural stability of the support pier 1 after pouring. The four steel bars 11 and the positioning steel bars 5 are used to connect and fix the vertical steel pipe 2, making the connection between the vertical steel pipe 2 of the scaffold and the slope 4 more stable. Finally, the slope 4, steel bars 11 and vertical steel pipe 2 are cast into a single concrete structure, which further improves the installation stability of the vertical steel pipe 2 on the steep slope 4.

[0026] To facilitate the connection between the reinforcing bar 11 and the slope 4, holes are provided on the slope 4 to facilitate the insertion of the reinforcing bar 11. The lower end of the reinforcing bar 11 is inserted into the hole and fixed with anchoring adhesive, so that the reinforcing bar 11 is tightly fixed to the slope 4.

[0027] The upper ends of the reinforcing bars 11 are all bent toward the vertical steel pipe 2 and are L-shaped, which makes it easy to tie them with the positioning reinforcing bars 5, so that the vertical steel pipe 2 is vertically set between the reinforcing bars 11.

[0028] The four reinforcing bars 11 are bound together with ring bars 12. Between the two lower-lying reinforcing bars 11 within the support pier 1, the roots are reinforced with tie bars 13. The ring bars 12 and tie bars 13 further enhance the structural stability of the steel structure inside the support pier 1.

[0029] A water platform 3 for placing vertical steel pipes is provided on the slope 4. The vertical steel pipes 2 are placed vertically on the water platform 3 to facilitate keeping them vertical during installation.

[0030] As a preferred embodiment, the support pier 1 is rectangular in size, measuring 220*240 mm. The diameter of the reinforcing bar 11 is 22 mm, the hole size is 26 mm, and the embedment depth is 20 d. Under this standard, the requirements for safe construction can be fully met.

[0031] The construction method and steps for this novel support pier are as follows, see below. Figure 5 :

[0032] S1. Clean the concrete surface; use a broom to scrape the concrete surface to remove loose stones and mud, so as to avoid affecting the construction of support 1.

[0033] S2. Conduct layout work to determine the position and size of each support 1; by conducting strength tests on the support 1 test blocks, each support 1 is 220*240 rectangular in size, which meets the construction requirements;

[0034] S3. Drill holes at the designated locations on the concrete surface using a drilling rig and install reinforcing bars. Each support pier 1 contains four 22mm diameter reinforcing bars 11, which are centrally symmetrically distributed around the vertical steel pipe 2. After the lower end of each reinforcing bar 11 is inserted into the hole, it is reinforced and stabilized with anchoring adhesive. The drilled holes are 26mm in size and buried at a depth of 20d. Through testing, it was found that using four 22mm diameter reinforcing bars 11, inserted into holes buried at a depth of 20d, and fixed with anchoring adhesive, can meet the construction needs of the support pier 1. The upper end of each reinforcing bar 11 is bent towards the vertical steel pipe 2 in an L-shape. This serves two purposes: firstly, it prevents the poured concrete from collapsing; secondly, it acts as a connecting and positioning component for the vertical steel pipe 2 of the scaffolding, improving the installation stability of the vertical steel pipe 2.

[0035] S4. The four steel bars 11 are reinforced by binding ring bars 12 around them. By binding the four steel bars 11 with ring bars 12, the structural strength between the four steel bars 11 is improved, making the structure of the support pier 1 more stable. Since the installation height of the steel bars 11 on the slope 4 is not consistent, in order to improve the overall stability of the steel bar 11 skeleton, multiple ring bars 12 can be used to reinforce the upper part of the four steel bars 11, up to the roots of the two steel bars 11 with higher horizontal positions. For the roots of the two steel bars 11 with lower horizontal positions, tie bars 13 can be used to reinforce each other.

[0036] S5. A 10mm*10mm water platform 3 is pre-reserved at the center of the support 1 as the base surface for the vertical steel pipe 2. The vertical steel pipe 2 is placed vertically on the water platform 3 and fixedly connected to four steel bars 11 by four positioning steel bars 5 respectively. In order to ensure the verticality of the vertical steel pipe 2 and facilitate subsequent installation, the installation position of the vertical steel pipe 2 is pre-reserved in this invention, which can greatly improve the safety of the scaffolding system. The water platform 3 can also be opened later, but the horizontality of the water platform 3 must be ensured to ensure that the vertical steel pipe 2 is installed vertically. In addition, four short steel bars 11 with a length of 15mm and a diameter of 10mm are used as positioning steel bars 5 to connect the vertical steel pipe 2 to the horizontal part of the four steel bars 11, so as to ensure the verticality of the vertical steel pipe 2.

[0037] S6. Erect the formwork; Use 14mm thick formwork to erect the support pier 1;

[0038] S7. Pour concrete support 1 and cure it. To meet the design strength, C30 concrete can be used for pouring.

[0039] S8. After the concrete has completely solidified, remove the formwork to complete the construction of support 1. Finally, build scaffolding on the vertical steel pipe 2 to complete the construction of the scaffolding platform.
