Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to an adjustable beam clamp used in the concrete pouring construction of a bathroom retaining beam. Background Technology

[0002] Bathroom retaining walls are an essential structural element for rigid waterproofing in bathrooms. During actual construction, various factors can influence the process, such as changes in room function requiring additional bathrooms or relocation of the bathroom location. New bathrooms often require the re-casting of concrete retaining walls or the reinforcement and heightening of existing retaining walls. The entire construction process necessitates formwork for the new retaining wall structure. Current formwork construction relies heavily on woodworking, resulting in significant waste and material consumption. Furthermore, the dismantling and construction processes have a substantial environmental impact on the relatively small area of ​​the room, failing to meet the material conservation and environmental protection requirements of green construction.

[0003] To address the aforementioned issues, existing technologies employ steel molds, which avoid dust generation and allow for the reuse of steel formwork, thus meeting the requirements of green construction. However, existing steel formwork fixing methods are less convenient than wooden formwork. They typically use threaded rods to secure the formwork, which is inconvenient to install. Furthermore, bathrooms are prone to dampness, and the reinforcing steel bars left in the concrete waterproof sill are susceptible to rust, posing a risk to the quality of the bathroom waterproof sill. Another method involves fixing the formwork with clamps, but these clamps are relatively simple and limited in specifications, making them unsuitable for construction work on waterproof sill structures of varying widths. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by the adjustable beam clamp of this utility model includes a left adjusting clamp plate, a right fixed clamp plate, and an adjusting pre-tightening mechanism; the left adjusting clamp plate and the right fixed clamp plate are combined to form an adjustable U-shaped bayonet structure, and an adjusting pre-tightening mechanism is installed at the combined installation part to adjust the spacing of the fixed U-shaped bayonet structure; the left adjusting clamp plate is composed of a vertical left clamp plate and a left horizontal telescopic sleeve, forming the L-shaped left part of the U-shaped bayonet structure; the right fixed clamp plate is composed of a vertical left clamp plate and a left horizontal telescopic sleeve, forming the L-shaped left part of the U-shaped bayonet structure; The right clamping plate and the right side transverse telescopic cylinder are fixedly arranged to form the L-shaped right side part of the U-shaped bayonet structure; the left side adjusting clamping plate and the right side fixed clamping plate are fitted into the left side transverse telescopic sleeve through the right side transverse telescopic cylinder to form a structure in which the distance between the vertical left clamping plate and the vertical right clamping plate is adjustable; the adjusting pre-tightening mechanism is provided with a pre-tightening screw, which is installed along the telescopic structure formed by the left side transverse telescopic sleeve and the right side transverse telescopic cylinder. One end is fixedly installed on the right side transverse telescopic cylinder, and the other end extends from the bottom left side of the left side transverse telescopic sleeve and is adjusted and fixedly installed with the left side transverse telescopic sleeve.

[0006] The pre-tightening mechanism is equipped with a fixing bolt and a pre-tightening nut on the pre-tightening screw. The fixing bolt is located at the right end of the pre-tightening screw, and the pre-tightening nut is installed on the left side of the pre-tightening screw. The installation position is adjustable.

[0007] The left side of the adjusting clamp is fixedly equipped with a pre-tightening nut mounting support plate on the left transverse telescopic sleeve, and a hole is opened at the center of the upper edge for the pre-tightening screw to pass through.

[0008] The right-side horizontal telescopic cylinder of the right-side fixed clamp is fixedly equipped with a fixing bolt mounting support plate, and a hole is opened at the center of its upper edge for the pre-tightening screw to pass through.

[0019] As attached Figure 1-3 As shown, the adjustable beam clamp of this utility model includes a left adjusting clamp plate 1, a right fixed clamp plate 2, and an adjusting pre-tightening mechanism 3.

The right fixed clamp plate 2 is composed of a vertical right clamp plate 21 and a right horizontal telescopic sleeve 22. The fixed assembly forms the L-shaped right side portion of the U-shaped bayonet structure; the left adjusting clamp 1 and the right fixed clamp 2 are fitted into the left transverse telescopic sleeve 12 through the right transverse telescopic cylinder 22, forming a structure in which the distance between the vertical left clamp 11 and the vertical right clamp 21 is adjustable; the adjusting pre-tightening mechanism 3 is provided with a pre-tightening screw 31, which is installed along the telescopic structure formed by the left transverse telescopic sleeve 12 and the right transverse telescopic cylinder 22, with one end fixedly installed on the right transverse telescopic cylinder 22, and the other end extending from the bottom left side of the left transverse telescopic sleeve 12, and adjusted and fixedly installed with the left transverse telescopic sleeve 12.

[0020] The pre-tightening mechanism 3 has a fixing bolt 32 and a pre-tightening nut 33 on its pre-tightening screw 31. The fixing bolt 32 is located at the right end of the pre-tightening screw 31, and the pre-tightening nut 33 is installed on the pre-tightening screw 31 along the left side of the pre-tightening screw 31.

[0026] Example 2

[0027] Combined with appendix Figure 1-3 As shown, the construction process and principle of the adjustable beam clamp of this utility model are illustrated.

[0028] 1. Assembly of the adjustable beam clamp: First, insert the pre-tightening screw 31 of the adjusting pre-tightening mechanism 3 from the right side of the right transverse telescopic cylinder 22, and then pass it through the hole of the fixing bolt mounting support plate 221 at the left end of the right transverse telescopic cylinder 22, so that the fixing bolt 32 abuts against the fixing bolt mounting support plate 221. Use the fixing locking sleeve to fix the pre-tightening screw 31 along the fixing bolt 32 to the fixing bolt mounting support plate 221; then, fit the left transverse telescopic sleeve 12 of the left adjusting clamp 1 and the right transverse telescopic cylinder 22 of the right fixing clamp 2 together, so that the pre-tightening screw 31 passes through the right end of the left transverse telescopic sleeve 12 and passes through the hole of the pre-tightening nut mounting support plate 121 at the left end of the left transverse telescopic sleeve 12; finally, install the pre-tightening nut 33 of the adjusting pre-tightening mechanism 3 from the left end of the pre-tightening screw 31 onto the pre-tightening screw 31, and adjust the position to meet the usage requirements.

[0029] 2. After setting up the formwork on both sides of the foundation structure of the backwater sill, install the left adjusting clamp 1 and the right fixing clamp 2 from the left and right sides above the beam opening, respectively, so that they are locked onto the formwork structure on the left and right sides.

[0030] 3. Adjust the position of the right horizontal telescopic cylinder 22 on the left horizontal telescopic sleeve 12 so that the vertical left clamping plate 11 and the vertical right clamping plate 21 are respectively pressed against the template on the left and right sides. At the same time, adjust the installation position of the pre-tightening nut 33 so that it is pressed against the pre-tightening nut mounting support plate 121 at the leftmost end of the left horizontal telescopic sleeve 12. Fix the structure and position of the left adjusting clamping plate 1 and the right fixing clamping plate 2 until the template support strength requirements are met.

[0031] 4. Concrete pouring operation is carried out between the formwork of the anti-water barrier to complete the pouring construction operation of the anti-water barrier.

[0032] 5. After the concrete has solidified, adjust the pre-tightening nut 33 outward along the pre-tightening screw 31 to separate the vertical left clamping plate 11 and the vertical right clamping plate 21 from the templates on the left and right sides respectively.

[0033] 6. Remove the adjusting pre-tightening mechanism 3 from above the beam opening to complete the disassembly of the adjustable beam opening clamp of this utility model. Finally, remove the template from the poured anti-water sill beam.

[0034] In the above process, step 1 can be installed and ready for use; only adjustment is needed during installation, making it convenient and quick. Steps 2 and 3, the formwork support operations, are easy to adjust, the pre-tightening effect is measurable, and the quality is reliable. Steps 5 and 6 complete the adjustment of the pre-tightening mechanism and the disassembly of the formwork, allowing for reuse and reducing construction costs. The entire process generates no waste, achieving green construction requirements.
