Technical Field

The invention relates to the field of building construction, in particular to a U-shaped adjustable jacking and a construction method.

Background

The jacking is common equipment in building construction, is used in cooperation with a steel pipe and a scaffold in the construction process, plays roles in adjusting the heights of the scaffold and the pipe frame, balancing and supporting heavy objects and bearing, and is used most in the construction process of plane construction commercial concrete pouring. The adjustable jacking utilizes the screw action of the screw rod, and the height of the upper support of the adjustable jacking can be adjusted to meet the height requirement of jacking objects. The adjustable jacking component mainly comprises: the jacking is used for contacting with the supported object and providing jacking force for the supported object; the screw rod is arranged below the upper support, the length of the screw rod is a thread, and the lower part of the screw rod is sleeved in the hollow steel pipe; the regulator is arranged on the lead screw and can rotate up and down along the threads, and the regulator is positioned at the pipe orifice of the hollow steel pipe below and rotates to achieve the adjustable function.

A lot of occasions of current adjustable top support are used for construction scaffold steel pipe or pour template below for support scaffold or template, adjustable top support belongs to hard support, often produces very big vibrations because of the construction on the scaffold, receives vibrations at the top support after, the steel pipe of top produces with the top support easily and slides, if slide seriously, still can take place to push up the consequence that the support drops, seriously influences construction safety. In order to avoid the slippage of the steel pipe above, conventional constructors can bundle the steel pipe and the jacking together by using steel wires, but the method is time-consuming, labor-consuming and low in efficiency. On the other hand, the construction production of steel pipe top is very big strong vibrations can cause the not hard up of distant structure for the steel structure of support distant place through the structure transmission.

Disclosure of Invention

The invention provides a U-shaped adjustable jacking and a construction method; the adjustable jacking can be used for supporting steel pipes, wood ridges or section steel and the like, and has the advantages that the adjustable jacking is not easy to slide when jacking, and supports are not easy to fall off; in addition, vibration on the supporting steel pipe can be partially eliminated, so that the vibration of the structure is smaller, the damage of the vibration to the structure can be prevented, and the construction noise is reduced.

In order to achieve the purpose of the invention, the technical scheme is as follows:

the U-shaped adjustable jacking comprises an upper support, wherein the center of the bottom of the upper support is fixedly connected with a lead screw, the lead screw is sleeved with an adjuster, the upper support is in a groove shape, and the middle parts of two side edges of the groove shape are provided with U-shaped grooves with the same shape; the U-shaped groove can be with the fine spacing of the pipe support steel pipe that the pop-up bore born, prevent that the outward appearance from sliding for columniform steel pipe side to side, even under the condition that the pipe support received very big vibrations, the pipe support steel pipe still can not break away from with the pop-up bore.

The upper section of the screw rod is hollow and tubular, a mandril is arranged in the hollow tube and can move up and down, the upper end of the mandril penetrates out of the screw rod and reaches the upper support, a central jacking block is arranged at the upper end of the mandril, and a pressure spring is arranged in the hollow tube below the mandril; the ejector rod and a pressure spring below the ejector rod are hidden in the hollow structure of the lead screw, the vibration of the pipe frame is transmitted to the ejector rod through the central ejector block, the ejector rod is transmitted to the pressure spring, the pressure spring absorbs the vibration energy, the vibration of the pipe frame can be finally reduced, and the looseness and the failure of a connecting node caused by the vibration of the whole structure of the pipe frame are avoided; in addition, due to the reduction of vibration, construction noise is correspondingly reduced, and the influence of construction on the surrounding environment is reduced.

The top of the central top block is 1-2cm higher than the bottom of the upper supporting U-shaped groove; when the state of relaxing, the pressure spring is in uncompressed state, just can guarantee like this that center kicking block and pipe support steel pipe priority contact when last support and pipe support steel pipe contact, absorbs its vibrations transmission to pressure spring department as far as possible.

The upper surface of the central ejector block is a concave curved surface, and the concave curved surface can increase the contact area between the central ejector block and the pipe frame steel pipe and better absorb the vibration from the pipe frame steel pipe; on the other hand, the central top block can also assist the U-shaped groove in positioning the steel pipe.

The center kicking block is made of rubber or the curved surface of the center kicking block is provided with a rubber cushion layer, the rubber is made of soft materials, the damping effect can be improved, and the contact area between the center kicking block and the pipe frame steel pipe can also be improved.

The construction method of the U-shaped adjustable jacking comprises the following steps:

A. after the pipe frame above the top is built, inserting a lead screw of an adjustable top support into a hollow steel pipe erected below, fixing an adjuster with a pipe orifice of the hollow steel pipe, adjusting the height of the lead screw to a distance which is not contacted with the pipe frame, and rotating the adjustable top support to a direction in which a U-shaped groove can be embedded with the pipe frame;

B. the plate-rotating adjuster lifts the screw rod, the upper support is gradually close to the pipe frame, the central ejector block is aligned to the pipe frame part needing to be supported and is abutted to the lower part of the steel pipe, the central ejector block is abutted to the surface of the steel pipe, and the screw rod is continuously lifted until the outer surface of the pipe frame is embedded into the bottom of the U-shaped groove;

C. when the adjuster rotates to a preset torque force, the rotation is stopped, and the installation of the adjustable jacking is completed;

D. when the construction is finished, the adjuster is reversely twisted, the screw rod is lowered, the upper support and the central jacking block are separated from the pipe frame, and the adjustable jacking can be integrally detached

Compared with the prior art, the invention has the substantive characteristics and the progress that:

1. the U-shaped groove can effectively position the pipe frame steel pipe, prevent the pipe frame steel pipe from sliding left and right, avoid the steel pipe from slipping and ensure the safety of construction.

2. The damping system of the central ejector block, the ejector rod and the pressure spring plays a good damping role on the pipe frame above, prevents the pipe frame from loosening due to construction vibration, reduces the noise of the construction vibration and reduces the influence of construction on the surrounding environment.
