Description

Technical Field

[0001] This utility model relates to the technical field of support system, specifically to a support system for slopes. Background Technology

[0002] In my country's construction engineering, scaffolding is a commonly used support system, widely applied to the bottom support of various cast-in-place structures. Typically, the foundation of the scaffolding is a flat ground or a reliable structural floor slab. However, in certain construction areas, some cast-in-place components are not situated on flat ground but rather on sloping terrain. Therefore, there is an urgent need to develop a scaffolding support system suitable for slopes, providing a stable foundation for the scaffolding and ensuring construction safety and smooth project progress.

[0003] Taking the Nan'ao Wharf Project (Port of Entry) (located in Dapeng New District, Shenzhen) as an example, its eastern side is adjacent to a slope. According to the design documents, this slope is mainly supported by lattice beams, and the top of the slope also requires the construction of a cast-in-place floor slab structure. This necessitates the construction of a reliable scaffolding support system on the slope to bear the loads of the scaffolding erection and the superstructure.

[0004] Existing technical solutions consider constructing multiple steps in the slope area and pouring a concrete foundation on top as a support base. However, this method has significant drawbacks: firstly, constructing steps will disturb the original slope structure; secondly, after the upper floor slab structure is poured, large equipment will have difficulty entering the area, making the subsequent treatment of the step foundation concrete a construction challenge.

[0005] To address the above technical problems, this utility model proposes a support system for slopes. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a support system for slopes, which provides stable support for scaffolding and superstructure loads, meets the requirements of strength, rigidity and stability, and is easy to install and dismantle, thus reducing construction costs.

[0007] The technical problem solved by this utility model is achieved through the following technical solution: A slope support system includes a slope grid beam, chemical anchors, steel plates, and a steel frame network platform. The chemical anchors are embedded in the slope grid beam, and the steel plates are fixed to the slope grid beam by the chemical anchors. The steel frame network platform is installed on the steel plates and is used to erect disc-lock scaffolding.

[0008] Furthermore, the steel frame network platform is a stepped steel frame network platform, which is composed of several layers of inverted L-shaped steel frame platforms. The inverted L-shaped steel frame platform includes a steel frame network plane and steel frame network columns. The steel frame network plane is formed by welding several I-beams in a crisscross pattern to form a network. The steel frame network columns are formed by welding several I-beams vertically to the lower end of the steel frame network plane.

[0009] Furthermore, several I-beams of the steel frame network columns are vertically welded to a steel plate, and the steel plate is pre-embedded and fixed to the slope grid beam.

[0010] Furthermore, the chemical anchor is an M20×260 chemical anchor.

[0011] Furthermore, the steel plate is a 300×400×12mm steel plate made of Q235B material.

[0012] Furthermore, the I-beam is a 25# I-beam made of Q235B material.

[0013] The advantages and positive effects of this utility model are: 1. This utility model relates to a slope support system, comprising a slope grid beam, chemical anchors, steel plates, and a steel frame network platform. The chemical anchors are embedded in the slope grid beam, and the steel plates are fixed to the slope grid beam by the chemical anchors.

It is economical, efficient, and environmentally friendly.

[0014] 2. The support system for the slope of this utility model has steel plates with dimensions of 300×400×12mm and material of Q235B; the I-beams are 25# I-beams and material of Q235B.

[0019] The steel frame network platform is a stepped steel frame network platform, which consists of several layers of inverted L-shaped steel frame platforms. The inverted L-shaped steel frame platform includes a steel frame network plane and steel frame network columns. The steel frame network plane is formed by welding several I-beams 3 in a crisscross pattern, and the steel frame network columns are formed by welding several I-beams 3 vertically to the lower end of the steel frame network plane.

[0020] Several I-beams 3 of the steel frame network columns are vertically welded onto steel plates 4, and steel plates 4 are pre-embedded and fixed onto slope grid beams 2.

[0021] Chemical anchor 5 is an M20×260 chemical anchor 5.

[0022] Steel plate 4 has dimensions of 300×400×12mm and is made of Q235B material.

[0023] I-beam 3 is 25# I-beam 3, made of Q235B material.

It is specifically designed for slope surfaces, and the overall structure possesses excellent strength, rigidity, and stability, meeting the support requirements.

Construction is convenient, and risks are controllable. Installation and dismantling are convenient and efficient, effectively reducing disturbance to the slope and lowering construction risks.

[0025] The working principle of this utility model: To construct a support system suitable for slopes, chemical anchors 5 are inserted into the upper part of the slope grid beam 2, and steel plates 4 are firmly anchored to the slope grid beam 2 using the chemical anchors 5. A steel frame network platform is installed on the steel plates 4, and the steel frame network platform is used to erect disc-lock scaffolding 6. This is accomplished through the following steps: Step 1, Measurement and Layout: Based on the calculated spacing, measure and lay out the lines on the slope grid beam 2; accurately mark the installation position of each chemical anchor 5; simultaneously mark the design height of the I-beam 3 of the required steel frame network column at the corresponding position to provide a basis for subsequent construction.

[0026] Step 2, Anchoring steel plate 4: Install chemical anchors 5 at the positions marked in step 1; use chemical anchors 5 to firmly anchor steel plate 4 to slope grid beam 2 to ensure reliable connection.

[0027] Step 3: Construct the steel frame network platform: (1) Install steel frame network columns: According to the design height of the I-beam 3 of the steel frame network column marked in step 1 and the actual slope of the slope grid beam 2, cut the bottom of the I-beam 3 of the steel frame network column into a bevel that matches the steel plate 4; fully weld the cut I-beam 3 of the steel frame network column to the embedded steel plate 4 to ensure that the weld quality meets the requirements; (2) Install the steel frame network plane: Weld the I-beams 3 of the steel frame network plane in a crisscross pattern to form a network. Weld the steel frame network plane to the upper end of the steel frame network column to form an inverted L-shaped steel frame platform. Several L-shaped steel frame platforms are constructed to form a stepped steel frame network platform, i.e., the steel frame network platform.

[0028] Step 4: Install the disc-lock scaffolding 6 onto the steel frame network platform.
