Description

Technical Field

[0001] This utility model relates to the field of building construction formwork engineering technology, specifically a construction structure for basement walls that does not require drilling. Background Technology

[0002] Basement formwork is widely used in building construction, especially in civil buildings. Wooden formwork is easy to install in basement construction, can be assembled freely regardless of size, and is suitable for pouring concrete structures or components with complex shapes and varying dimensions. The amount of formwork used needs to be optimized based on the basement's floor area, flow section divisions, and the proportion of wall panel formwork. Traditional basement wooden formwork construction typically involves drilling standard holes in the wooden formwork on both sides of the walls to install water-stop tie bolts for fixation. After drilling the holes, when dismantling and reusing the formwork, exposed concrete vibration at the holes can affect the quality and appearance of the concrete. Even if the holes are sealed, it is difficult to achieve a smooth surface when reused. Because the perforated formwork is difficult to use as a whole panel in subsequent structural construction, it is usually cut into smaller panels, resulting in a high formwork breakage rate, which is detrimental to construction cost control and does not conform to the concept of green construction. During reuse, the removal time of the roof slab formwork is limited by the concrete strength, and the use of conventionally perforated wall formwork after removal is restricted. When used on the roof slab formwork, sealing is required, resulting in unnecessary labor and material costs.

[0003] However, existing conventional timber formwork projects still have certain problems during routine construction: In practical use, the following problems still exist: The treatment of water-stop tie rods on both interior and exterior walls requires cutting the exposed rod heads. After the cut is smooth, rust prevention and plastering are performed. After sealing, the plaster surface is higher than the structural surface, and the overall appearance is generally poor due to the varying skill levels of the repair workers. When installing vertical secondary keels, nails need to be temporarily driven into the formwork to fix them. The treatment of these nail holes also results in unnecessary waste during decoration and exterior wall waterproofing.

[0004] To address the aforementioned issues, an innovative design was developed based on the conventional installation of basement wall formwork. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling-free construction structure for wooden formwork of basement walls to solve the fixing problem mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A basement wall wooden formwork construction structure without drilling includes a whole wooden formwork board 1, strips 2, square panels 3, composite panels 4, wing ring bolts 5, water-stop bolts 6, secondary keel 7, main keel 8, mountain-shaped clips 9, and mountain-shaped nuts 10.

[0007] The wall formwork assembly consists of wooden formwork panels 1 and composite panels 4, arranged at intervals. Composite panels 4 are composed of strips 2 and square plates 3, with the square plates 3 positioned to reinforce the water-stop bolts. Composite panels 4 are used to reinforce the water-stop bolts 6 and form the enclosure for the vertical secondary keel 7. The square plates 2 installed on the strips 2 form a groove structure, allowing the bolt heads to be directly filled after the concrete is poured, preventing any protrusion from the surface layer. Winged ring bolts 5 extend from the composite panels 4 in the opposite direction, forming a temporary enclosure structure for the vertical secondary keel 7 with the strips 2, U-shaped clips 9, and U-shaped nuts 10, preventing the secondary keel 7 from lacking a fixing measure before the main keel 8 is installed. Water-stop bolts 6 are installed at the water-stop bolt holes in composite panels 4, forming a wall formwork reinforcement system with the main keel 8, U-shaped clips 9, and U-shaped nuts 10.

[0008] Compared with the prior art, the beneficial effects of this utility model are: Reducing the need for bolt hole sealing and cutting, and using whole-slab casting improves the appearance and quality of the concrete. Simultaneously, eliminating the need for drilling in the formwork increases its reusability and reduces material costs. The temporary secondary joist enclosure structure effectively solves the problem of fixing the formwork without a main joist, avoiding manual nailing of the formwork, effectively enabling pre-control, and extending the formwork's service life.

[0013] 2. Square panels 3 are mass-produced in a woodworking factory using old templates, with panel dimensions of 50mm × 50mm.

[0014] 3. A winged screw 5 is made by welding a standard screw rod and a 3mm thick, M16 hole, and a D50 round washer.

[0015] 4. The square plate 3 is fixed on the strip 2, and the spacing between the center points of the square plate 3 is the spacing of the water-stop tie bolts, forming the composite plate 4.

[0016] 5. Holes are made in the combination plate 4 according to the spacing of the water-stop screws to form the water-stop screw hole positions; and two holes are made separately on both sides of the combination plate 4 to form the wing ring screw 5 hole positions.
