Description

Clamps for building construction

technical field

The utility model relates to a clamp for building construction.

Background technique

Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. Hoisting refers to the general term for the installation and positioning of equipment by a crane or a lifting mechanism. Hoisting generally requires the cooperation of spreaders (or called slings), which are manufactured by professional manufacturers. Introduce hoisting technology, especially professional websites using crane hoisting technology, such as the home of crane hoisting technology, etc. For the rolling method used in local construction to load and unload mobile equipment, the thickness of the rollers must be consistent, and the annual width should be 50cm longer than the width of the supporting row. It is strictly forbidden to fill the rollers with gloves. When loading and unloading the truck, the slope of the rolling edge shall not be greater than 20°. The raceway shall be set up flat and firm, the joints shall be staggered, and the rolling speed shall not be too fast. A slip rope shall be used if necessary. During the installation process, if any problem is found, measures should be taken in time, and the lifting should be continued after treatment. When hoisting large-scale tower equipment with pick-up poles, multiple winches are operated jointly, and the hoisting speed of each hoist must be roughly the same. It is necessary to ensure that the force on each lifting point on the tower body tends to be roughly uniform, so as to avoid uneven force on the tower body. out of shape. When the tower tank is hoisted by the slewing method or the knocking down method, the hinge installed at the bottom of the tower body must have the ability to resist the horizontal thrust generated during the hoisting process. , let it slowly fall into the foundation to avoid accidents and deformation. When installing equipment on a frame or a building, its strength and stability must meet the requirements of the installation conditions. After the equipment is installed and positioned, it must be connected and fastened or welded according to the requirements of the drawings. The decoupling can only be done after the strength and stability of the design requirements are met, otherwise it must be temporarily fixed. Do not push or pull the joystick violently during the operation. Before starting to lift, check that the clutch lever must be in the disconnected position. The free fall operation can only be used when the hook is lowered or when the suspended load is less than 30% of the allowable load, and emergency braking during free fall is prohibited.

The current existing clamps for hoisting are a tool for clamping, fastening, or hoisting, and are widely used in industries such as metallurgy, transportation, railways, ports, and the like. However, the clamping effect of the existing construction clamps is not good, the structure is not firm, and the application range is not wide.

A compression spring is installed between the outside of the connecting arm and the top of the caliper body.

Preferably, the inner side of the pliers body is provided with anti-slip lines, so that the inner side of the pliers body has an anti-slip function.

Preferably, both ends of the compression spring are respectively welded to the connecting arm and the caliper body to keep the compression spring firmly installed.

Preferably, the screw rod and the vertical rod are vertically arranged, and the vertical rod can conveniently drive the screw rod to rotate and adjust the position of the stopper at the other end of the screw rod.

As a preference, a limiting arm is also installed in the hinge seat through a limiting screw, and the limiting arm can limit the distance between the pliers to prevent the pliers from opening too much.

Preferably, the tops of the limit arms are connected to each other by limit screws, the limit arms can move, and the limit arms can move in the hinge seat.

Preferably, the screw rod is threadedly connected with the pliers body, and threaded holes are drilled at corresponding positions of the pliers body, so that the screw rod can be installed in the threaded holes.

The technical effect of the utility model is mainly reflected in the following aspects: two pliers are provided and the bottoms are horizontally bent inward, so that the pliers can prevent the clamped items from falling, keep the clamping effect good, and compress the spring Make the clamp body in the expanded state, which is convenient for clamping objects; the bottom of the connecting arm is installed in the hinge seat through the limit screw, the bottom of the boom is connected with the connecting arm through the limit screw, and the top of the boom is connected to each other through the limit screw , to keep the structure firm and able to move at the same time; a screw is installed in the middle of the pliers, one end of the screw is welded with a vertical rod, and the other end of the screw is welded with a stopper, turning the screw can adjust the distance between the stopper and the inner side of the pliers. When fixing without clamping with a stopper, five pieces in a bag can be placed inside the pliers body, keeping a wide range of use.
