Description

Technical Field

[0001] The invention relates to the technical field of foam concrete construction, and in particular to a sliding assembly template structure used for layered and block casting of foam concrete. Background Art

[0002] Due to its low density, foam concrete is often used in soft soil areas or engineering construction with strict settlement requirements, such as embankment filling in soft soil sections, bridge abutment backfill, road widening and other large-volume foam concrete pouring projects.

[0003] CJJ / T 177-2012 "Technical Specifications for Filling Bubble-Mixed Lightweight Soil" clearly requires that large-volume foam concrete pouring must be carried out in a layered and block-by-block manner, and settlement joints must be set between the blocks. The existing formwork used for layered and block-by-block pouring of foam concrete mainly uses fixed formwork and mobile formwork. Among the mobile formwork, the detachable mobile formwork is more popular with engineering technicians because it is easy to carry after disassembly. For example, the Chinese patent "A Rapid Disassembly and Assembly Formwork for Cast-in-Place Foam Lightweight Soil Roadbed" authorized on February 8, 2022 proposes a formwork that can quickly disassemble and assemble the formwork panel by moving abutting rollers. However, this method still has the following disadvantages:

[0004] (1) The template proposed in this method lacks a device to align with the boundary of the foam concrete block of the lower layer when pouring the foam concrete of the current layer. When affected by human or environmental factors in actual construction, it is difficult to form a settlement joint that connects the upper and lower layers, which poses a hidden danger to the engineering quality.

[0005] (2) The size of the template proposed by this method cannot be adjusted after production, and it cannot be adjusted according to the size of the casting blocks in actual construction, so its applicability is poor; Summary of the Invention

[0006] In order to solve the above technical problems, the present invention proposes a sliding assembly formwork structure suitable for layered and block casting of foam concrete, aiming to improve the applicable range and disassembly efficiency of the formwork casting size, and effectively control the construction quality of the settlement joints.

2. A sliding assembly formwork structure for layered and block casting of foam concrete according to claim 1, characterized in that: A thin rod (19) is installed at each end of the flexible material.

3. The sliding assembly formwork structure for layered and block casting of foam concrete according to claim 1, characterized in that: The vertical rod (1), type I lower cross bar (7), type II lower cross bar (8), type III lower cross bar (9), type I upper cross bar (4), type II upper cross bar (5), type III upper cross bar (6) and the matching type I fasteners (10), type II fasteners (11) and vertical support rods (12) are all series products, that is, they are manufactured in various models to meet the needs of various layered and block casting.

4. The sliding assembly formwork structure for layered and block casting of foam concrete according to claim 1, characterized in that: The sliding assembly template structure further comprises a plurality of type I leak-proofing components (2) and a plurality of type II leak-proofing components (3), wherein the type I leak-proofing components (2) and the type II leak-proofing components (3) are both made of settlement joint filling materials, the type I leak-proofing components (2) have a right-angled cross section with thickness, are installed at the vertex of the rectangular C and cover the area at this position and the adjacent area not covered by the blocking component (13), the type II leak-proofing components (3) are thin plates, are placed at the splicing vertical rods of the non-rectangular C vertex and cover the area at this position and the adjacent area not covered by the blocking component (13), the type I leak-proofing components (2) and the type II leak-proofing components (3) are both closely attached to the inner side of the blocking component (13), and the type I leak-proofing components (2) and the type II leak-proofing components (3) are collectively referred to as leak-proofing components.

5. The sliding assembly formwork structure for layered and block casting of foam concrete according to claim 4, characterized in that: The plugging component is trimmed after the j-th layer of foam concrete (14) is completed, and the top elevation of the trimmed plugging component is lower than the elevation of the top surface of the j-th layer of foam concrete (14) block, j=1, 2, ..., A; The fixing method of the leak-proof component is as follows: When j=1, the lower end of the leak-proof component is closely attached to the bag-blocking component (13) and inserted into the foundation, and the upper end is closely attached to the bag-blocking component (13) and fixed to the upper crossbar through a clamp; When j>1, the lower end of the leak-proof component is closely attached to the pocket member (13) and inserted into the expansion joint of the j-1 layer of foam concrete (14), and is adjacent to the top surface of the trimmed j-1 layer of leak-proof component, and the upper end is closely attached to the pocket member (13) and fixed to the upper crossbar by a clamp.
