Abstract
A hanging steel bar for cement cast-in-place piles comprises a main bar, an elevation control bar and a bayonet. The elevation control bar is mounted at the upper end of the main bar, the bayonet is disposed at the lower end of the main bar and consists of an upper fixed bayonet and a lower movable bayonet, the lower movable bayonet is connected with the lower end of the main bar via a rotating shaft, the upper fixed bayonet bar is arranged above the lower movable bayonet and fixedly connected with the main bar, clamp rings corresponding to each other are arranged at two ends of the each of the upper fixed bayonet and the lower movable bayonet, and a first pin and a second pin are respectively arranged on the elevation control bar via a first rope and a second rope. As the lower movable bayonet capable of rotating is used in the hanging steel bar for cement cast-in-place piles, the lower movable bayonet can be locked by the first pin so that the lower movable bayonet can bear weight of a reinforcement cage. When the reinforcement cage is located in place, the hanging steel bar can be detached conveniently after the lower movable bayonet is released by means of pulling off the first pin and the second pin. In addition, the hanging steel bar can be reused, thereby saving materials and reducing cost.
Description
Technical field:
The utility model relates to architectural furniture, and particularly the servicing unit during the cement grouting stake specifically is a kind of muscle that hangs that is used for the cement grouting stake.
Background technology:
Extensively use bored pile in the highrise building foundation, need to adopt the skeleton of reinforcing cage as bored pile in bored pile, reinforcing cage need be laid in place in advance.But rising of steel cage or sinking in the engineering filling process, usually occur, cause effective length deficiency or stake top mark height on the low side.In the prior art, the absolute altitude of control reinforcing cage usually adopts " hanging muscle ", and " the hanging muscle " of using on the common engineering not only can't effectively control the come-up or the sinking of reinforcing cage, and all is disposable inputs, and the wasting of resources is big, work efficiency is low.
The utility model content:
The purpose of this utility model is to provide a kind of muscle that hangs that is used for the cement grouting stake, described this hanging muscle and will solving prior art and be used for hanging muscle and can not reusing the technical problem that causes construction cost high of castinplace pile of cement grouting stake that be used for.
The purpose of this utility model is achieved through the following technical solutions: comprise mobile jib, absolute altitude control lever and bayonet socket, described absolute altitude control lever is installed on the upper end of described mobile jib, described bayonet socket is installed on the mobile jib lower end, wherein, described bayonet socket is made of last fixedly bayonet socket and following movable bayonet socket, movable bayonet socket links to each other with the mobile jib lower end by rotating shaft down, upward fixedly bayonet socket is located at down movable bayonet socket top, and fixedly connected with mobile jib, be provided with corresponding collar at last fixedly bayonet socket and following movable bayonet socket two ends, on the absolute altitude control lever, be respectively equipped with first latch and second latch by first rope and second rope.
Mobile jib and absolute altitude control lever are made of reinforcing bar or steel pipe, are provided with nut between mobile jib and the absolute altitude control lever.
Operating principle of the present utility model is: before the descending reinforcing cage, last fixedly bayonet socket and following movable bayonet socket block the reinforcing rib of reinforcing cage, plug first latch and second latch, first latch prevents down that movable bayonet socket rotates, and second latch prevents that reinforcing cage from coming off, reinforcing cage is after design elevation, by second rope second latch is drawn back, draw back first latch then, discharge movable bayonet socket down, movable bayonet socket rotates under action of gravity and is vertical state down, hangs muscle and can extract recycling.Also can control reinforcing cage top mark height by the absolute altitude control lever, can also carry out more closely spaced adjusting, so can accurately determine the position that reinforcing cage is transferred by originally hanging muscle by the nut between absolute altitude control lever and the mobile jib.
The utility model is compared with prior art, and its effect is actively with tangible.Adopt rotating movable bayonet socket down at the muscle that hangs that is used for the cement grouting stake, this activity bayonet socket can be by first latch locking, guarantee to bear the weight of reinforcing cage, when reinforcing cage is put into, draw back first latch and second latch, discharge movable bayonet socket down, can take out easily and hang muscle, can reuse, save material, reduce cost.Mobile jib and absolute altitude control lever are made of reinforcing bar or steel pipe, are provided with nut between mobile jib and the absolute altitude control lever, by adjusting nut, can carry out the adjusting of small distance in the basic enterprising step that the absolute altitude control lever is regulated, and accurately control the position of reinforcing cage.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the utility model is used for the muscle that hangs of cement grouting stake, comprise mobile jib 1, absolute altitude control lever 2 and bayonet socket, described absolute altitude control lever is installed on the upper end of described mobile jib, described bayonet socket is installed on the mobile jib lower end, wherein, described bayonet socket is made of last fixedly bayonet socket 3 and following movable bayonet socket 4, movable bayonet socket 4 links to each other with mobile jib 1 lower end by rotating shaft down, upward fixedly bayonet socket 3 is located at down movable bayonet socket top, and fixedly connected with mobile jib, be provided with corresponding collar at last fixedly bayonet socket 3 and following movable bayonet socket 4 two ends, on absolute altitude control lever 2, be respectively equipped with first latch 7 and second latch 8 by first rope 5 and second rope 6.Mobile jib 1 and absolute altitude control lever 2 are made of reinforcing bar or steel pipe, are provided with nut 9 between mobile jib 1 and the absolute altitude control lever 2.
Each reinforcing cage needs two to hang muscle and hang during concrete the use, hanging muscle is placed on the horizontal steel pipe by the absolute altitude control lever, can control reinforcing cage top mark height by the absolute altitude control lever, can also carry out more closely spaced adjusting by the nut between absolute altitude control lever and the mobile jib, so can accurately determine the position that reinforcing cage is transferred by originally hanging muscle.When being in place, after the perfusion part, treat that reinforcing cage can not float just can draw back latch, take out and hang muscle, reuse.
Claims (2)
1. muscle that hangs that is used for the cement grouting stake, comprise mobile jib, absolute altitude control lever and bayonet socket, described absolute altitude control lever is installed on the upper end of described mobile jib, described bayonet socket is installed on the mobile jib lower end, it is characterized in that: described bayonet socket is made of last fixedly bayonet socket and following movable bayonet socket, movable bayonet socket links to each other with the mobile jib lower end by rotating shaft down, upward fixedly bayonet socket is located at down movable bayonet socket top, and fixedly connected with mobile jib, be provided with corresponding collar at last fixedly bayonet socket and following movable bayonet socket two ends, on the absolute altitude control lever, be respectively equipped with first latch and second latch by first rope and second rope.
2. the muscle that hangs that is used for the cement grouting stake as claimed in claim 1 is characterized in that: mobile jib and absolute altitude control lever are made of reinforcing bar or steel pipe, are provided with nut between mobile jib and the absolute altitude control lever.
