Description

Technical Field

[0001] This application relates to the field of hydropower engineering construction technology, and in particular to an integrated device for slope-adhesive concrete construction. Background Technology

[0002] Conventional slope lining concrete construction involves segmented pouring along the slope, using steel formwork and pouring from bottom to top. Concrete is pumped into the formwork using a boom pump. End formwork and corner formwork are assembled from ordinary plywood, secured with reinforcing bars and tie rods. The work platform for formwork erection, concrete pouring, and vibration is erected along the slope from bottom to top using a coupler-type steel pipe scaffold. This conventional method requires erecting scaffolding upwards after each section of concrete is poured, followed by reassembling the formwork and installing secondary and main supports. This process is cumbersome, time-consuming, inefficient, and impacts the project schedule. Furthermore, as the pouring height increases, the scaffolding height also increases, increasing safety risks. Utility Model Content

[0003] To solve or partially solve the problems existing in the related technologies, this application provides an integrated device for slope concrete construction. The device moves up and down after the concrete is poured to serve as a formwork support and construction platform for the next batch of concrete.

[0004] The first aspect of this application provides an integrated device for slope concrete construction, including: a diagonal bracing template, secondary ribs, main ribs, a working platform, and hooks. The diagonal bracing template includes multiple steel templates connected in sequence. Secondary ribs are arranged horizontally and main ribs are arranged vertically on the diagonal bracing template to form an integral whole. The diagonal bracing template is connected to the working platform to form a triangular structure, and the diagonal bracing template is tangent to the slope. Hooks are also symmetrically installed on the upper edge of the diagonal bracing template.

[0005] The diagonal bracing formwork consists of six steel formwork panels arranged in a line. Connection holes are drilled at the joint surfaces of the steel formwork panels, and the panels are connected by bolts and nuts.

[0006] The work platform includes uprights and horizontal and vertical bars that form a rectangular work surface, which are installed on the uprights. The rectangular work surface and the bottom of the uprights are connected to the template.

[0007] Safety nets are installed at the bottom and outside of the work platform.

[0008] The technical solution provided in this application may include the following beneficial effects:

[0009] This application provides an integrated device for slope-facing concrete construction. After each concrete pour is completed, a conventional truck crane is used to move the device upwards to serve as the formwork support and construction platform for the next concrete pour, eliminating the need to rebuild the formwork support and construction platform. This device features a simple structure, high turnover efficiency, optimized construction procedures, and improved construction efficiency. The integrated design reduces the cumbersome installation of formwork support systems and the erection of construction platforms before each concrete pour, optimizing construction procedures, accelerating construction progress, reducing resource input, saving costs, and eliminating the need for conventional scaffolding erected along the slope, thus reducing construction risks.

[0020] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0021] Figure 1 This is a schematic diagram of the integrated device for slope-attached concrete construction shown in the embodiments of this application.

[0022] like Figure 1 , Figure 2The diagram shows an integrated device for slope-supporting concrete construction, comprising: a diagonal bracing formwork 1, secondary ribs 2, main ribs 3, a working platform 4, and hooks 5. Based on the single-section pouring width of the slope-supporting concrete, conventional steel formwork is arranged in a line and connected and tightened using bolts and nuts to form a single diagonal bracing formwork 1. Secondary ribs 2 are arranged horizontally and main ribs 3 are arranged vertically on the diagonal bracing formwork 1 to form a whole. The working platform 4 is constructed using scaffolding steel pipes in a triangular shape and welded and fixed to the main ribs 3 of the formwork. The diagonal bracing formwork 1 is tangent to the slope. Two U-shaped hooks 5 made of round steel are installed on the upper edge of the diagonal bracing formwork 1 as lifting points. A standard crane can be used to achieve integrated formwork support and movement of the construction platform within the section.

[0023] One specific construction method:

[0024] (1) The diagonal bracing template 1 is made of several steel templates with a panel thickness of not less than 5mm connected into a whole by M16 bolts. Q235 steel is selected for the steel template. According to the single-section pouring width of the slope concrete, which is generally 12m, 6 steel templates of 1500mm×1500mm are selected and arranged in a line. Φ18mm holes are drilled on the joint surface of the templates and connected and tightened by M16 bolts and nuts to form a whole diagonal bracing template 1 with a size of 1500mm×12000mm.

[0025] (2) The secondary ribs 2 and main ribs 3 of the template are made of structural steel and welded to the whole steel template. The secondary ribs 2 are arranged with a single 16# channel steel @ 500mm, and the main ribs 3 are arranged with two 16# channel steels @ 500mm. The template and the secondary ribs 2, and the secondary ribs 2 and the main ribs 3 are fully welded together, and the weld height is not less than 10mm.

[0026] (3) The working platform 4 is constructed using common, standard-compliant Q235 seamless steel pipes. The working platform 4 is designed in a triangular shape, including uprights, horizontal bars, and longitudinal bars. The horizontal bars near the concrete end and the bottom end of the uprights are fully welded to the secondary ribs 2 of the formwork. Anti-slip fasteners are used to connect the steel pipe members. The steel pipe diameter is 48.3 mm, the wall thickness is 3.6 mm, and the material properties of the steel pipe should meet the requirements of standard JGJ130.

[0027] (4) The upright extends 1200mm beyond the center line of the horizontal bar and also serves as a guardrail. A wooden board no less than 5cm thick is tied and erected on the horizontal bar to serve as a construction work platform. Safety netting is installed at the bottom and outside of the platform in accordance with safety protection requirements.

[0028] (5) The lifting hook 5 shall be made of Φ20mm round steel welded into a U-shape and welded to the frame of the device. The clear distance between the U-shaped hooks 5 shall not be less than 5cm. The selection of the wire rope and the local compressive strength of the hook 5 shall meet the requirements and shall be verified and checked as follows:

[0029]

[0030] In the formula, —Local compressive stress in hook 5;

[0031] K—Dynamic coefficient, taken as K=1.5;

[0032] Q—Load weight;

[0033] b—Firming width of hook 5;

[0034] —Diameter of the pressure-bearing part of the hook 5;

[0035] —The allowable stress for local bearing capacity of hook 5 is taken as 0.9fc.

[0036] In this scheme, a 12m long single-section concrete block is used as an example for calculation and analysis: Hook 5 is made of Φ20mm round steel, with a local bearing capacity allowable stress of 0.9 * 210 MPa = 189 MPa; the lifting wire rope is 20mm; the U-shaped hook 5 is made of bent 20mm round steel; the load weight, including steel plates, side ribs, main ribs 3, steel pipe scaffolding, etc., is approximately 1.63t. Therefore, according to the above formula:

[0037]

[0038] The device is used in the construction of slope lining concrete. The single-section steel formwork is connected by bolts to form an integral inclined support formwork 1. The entire inclined support formwork 1 can be moved up and down, eliminating the need for formwork assembly work for the lower section of concrete. The secondary ribs 2 and main ribs 3 are made of I-beams and welded to the inclined support formwork 1 to form an integral whole. This results in high strength and improved rigidity of the formwork. The double-backed main ribs 3 also provide support for the formwork tie rods, ensuring safety and reliability.
