Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to an adjustable clamp for a temporary bracket attached to a wall. Background Art

[0002] In the process of inspection and monitoring of civil air defense projects and other large facilities, it is often necessary to work in large spaces or at heights in order to install and debug related monitoring equipment. In order to ensure the safety of workers, a device called a safety ladder box is usually used to provide a safe access. When installing the wall-mounted rods in the existing safety ladder box, welding technology is generally used. Specifically, a steel plate is welded on the steel pipe, and then the steel plate is connected to the steel plate on the safety ladder by bolts. However, this method has significant defects in practical applications.

[0003] First, under the action of external forces such as wind loads, the ladder box rods will be subjected to tension. Since the node parts are connected by welding, these tensions are mainly borne by bolts. This connection method not only concentrates the force on the bolts and welding points, but also easily causes local points to be weak and unevenly stressed, thus affecting the stability of the overall structure. Secondly, the use of welded steel plates also increases the difficulty of steel pipe turnover. Once the steel pipe is welded to the steel plate, its scope of use is greatly limited, and it can basically only be used for specific ladder boxes. This not only reduces the versatility and flexibility of the steel pipe, but also increases the cost of storage and management. In addition, the residual stress generated during the welding process will have a negative impact on the stress performance of the steel. After long-term use, the steel in the welded part may experience performance degradation or even potential hazards, thereby threatening the safety of the operators. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0020] like Figure 1-Figure 4 As shown, a temporary bracket wall-attached adjustable fixture includes a center frame 1, the center frame includes a mounting plate 11, side plates 12 are provided on both sides of the mounting plate, a central connecting plate 13 is formed in the middle of the mounting plate, the central connecting plate is connected with a left clamp, and the left clamp is connected with a right clamp 2 through a first bolt 23 and a first nut 24. The detachable connection between the left clamp and the right clamp facilitates installation and disassembly, and improves the convenience of use. Two sets of clamping components are slidably matched on the center frame, and the steel beam of the safety ladder cage is clamped between the two sets of clamping components.

[0021] In at least one embodiment, the clamping assembly includes a moving plate 33, the moving plate is connected to a sliding rod 31, the end of the sliding rod is provided with a limit plate 32, the moving plate is fixedly connected to a clamping steel plate clamp, and in cooperation with it, the mounting plate is provided with a slide groove 111, the sliding rod is slidably matched in the slide groove, the side plate is provided with a threaded hole, the moving plate is rotatably connected to a guide rod 35, and the guide rod is locked and fixed by a butterfly screw 36 after passing through the threaded hole. This design allows the clamping assembly to be flexibly moved and fixed, so as to adapt to safety ladder cage steel beams of different sizes, and improve the adaptability and adjustability of the clamp.

[0022] Furthermore, the hoop steel plate clamp includes a side clamp 34, and the side clamp is connected with a bending plate 37. The design of the side clamp and the bending plate increases the contact area between the clamp and the steel beam of the safety ladder cage, and improves the stability and reliability of the clamp.

[0023] In at least one embodiment, the mounting plate is provided with a longitudinal limiting mechanism 4, such as Figure 3 As shown, the longitudinal limiting mechanism includes a threaded rod 42, a threaded hole is provided on the mounting plate, a threaded rod is threadedly connected in the threaded hole, a pressing plate 41 is provided at the end of the threaded rod, and a clamping nut 43 is installed on the threaded rod. The longitudinal limiting mechanism can achieve longitudinal limiting of the steel beam of the safety ladder cage through the cooperation of the threaded rod and the clamping nut, further enhancing the stability and safety of the fixture.

[0024] Further, the left clamp includes a left arc plate 14, on which a left connecting plate 15 is provided, and the right clamp includes a right arc plate 21, on which a right connecting plate 22 is provided, and the left connecting plate and the right connecting plate are locked and fixed by a first bolt 23 and a first nut 24. The arc plate design of the left clamp and the right clamp can better adapt to the shape of the steel pipe, thereby improving the clamping effect and stability of the clamp.

[0025] The solution is refined, and a steel pipe is clamped between the left arc plate and the right arc plate.

[0026] Furthermore, the left curved plate and the right curved plate are both provided with a rubber shock-absorbing layer. The rubber shock-absorbing layer can consume a part of the load under high wind load or repetitive wind load conditions, and change the node into an elastic-plastic node, thereby reducing the force of the load on the ladder box and improving the seismic performance and safety of the fixture.

[0027] Working method: Install rubber shock-absorbing layers on the left and right clamps to increase the friction between the clamps and the steel pipe, while reducing the vibration and noise that may be generated during installation and use. The left and right clamps are locked and fixed by the first bolt and the first nut to ensure that the steel pipe is firmly clamped between the left and right clamps. Pass the guide rod through the through hole on the side plate, and adjust the movable plate to move to the appropriate position along the slide groove on the mounting plate. At this time, the butterfly screw should remain loose so that the movable plate can move freely. Fix the clamp steel plate clip on the movable plate to ensure that the clip can be firmly attached to the steel beam of the safety ladder cage. Install the longitudinal limit mechanism, adjust the position of the pressure plate by rotating the threaded rod so that it is pressed against the steel beam of the safety ladder cage, and then tighten the clamping nut to fix the threaded rod.

[0028] The steel pipe clamp of the present invention is used to fix two vertical steel pipes between the steel beams of two safety ladder cages. Horizontal transverse scaffolding rods are installed on the fixed steel pipes to construct a stable scaffolding structure. Wall attachment rods are installed to attach the scaffolding structure to the tunnel wall to enhance the stability and bearing capacity of the entire structure.

[0029] Through the above steps, a stable and reliable scaffolding system can be quickly built to provide a safe and convenient working environment for construction workers. At the same time, the clamp design of the present invention is flexible and adjustable, suitable for safety ladder cage steel beams of different sizes and shapes, and has high practicality and adaptability.
