Example 1
The embodiment provides a method for installing a pipeline shared support, which is used for installing the pipeline shared support in a basement with a floor slab with a slope and comprises the following steps:
determining the elevation of the shared bracket 1 for the head and the tail of the two sections of pipelines in the arrangement direction, and correspondingly installing the shared bracket 1 for the head and the tail of the two sections of pipelines;
a steel wire rope 2 extending along the arrangement direction is connected between the first-section and last-section pipeline shared supports 1, the steel wire rope 2 is provided with two nodes sequentially arranged along the extension direction, the two nodes on the steel wire rope 2 are respectively connected to the same positions of the first-section and last-section pipeline shared supports 1, the steel wire rope 2 is straightened at the position between the two nodes, and the included angle between the position of the steel wire rope 2 between the two nodes and the horizontal plane is consistent with the gradient of the floor slab;
the part between two nodes of the steel wire rope 2 is used as an elevation reference object of the shared support 1 for other pipelines, and the shared support 1 for other pipelines is arranged between the shared supports 1 for the head and the tail of the two pipelines.
Referring to fig. 1, a side view of the present embodiment is shown.
Firstly, it can be understood that, because the ground layer has a slope, the top plate 3 and the bottom plate 4 as the floor slab also have a slope, the elevations of the common supports 1 for all the pipelines are different along the arrangement direction, and the common supports 1 for the first and the last pipelines are in a form of limiting one at a high position and one at a low position.
In the embodiment, a straight steel wire rope 2 is mainly used as a flexible part for connecting the first and the last pipeline shared supports 1, which mainly takes into consideration that: the arrangement span of the pipeline sharing support 1 is large, the linear length of the pipeline sharing support is even more than fifty meters in a partial area, if a common connecting rope with low strength is adopted as a flexible part for connecting the head and tail two pipeline sharing supports 1, the central part of the common connecting rope is very easy to fall, and therefore the steel wire rope 2 with higher strength is correspondingly adopted as the flexible part for connecting the head and tail two pipeline sharing supports 1 in the embodiment.
In addition, regarding determining the elevation of the rest pipeline shared bracket 1 by using the steel wire rope 2 as the elevation reference object of the rest pipeline shared bracket 1, it can be understood by those skilled in the art that:
the height difference between the corresponding position on the steel wire rope and the corresponding shared support of the pipeline to be installed is equal to the height difference between the node and the shared support elevation of the first section/node and the tail section pipeline.
In the preferred embodiment, the common support 1 for the first and last two sections of pipes is provided with a tightening structure for connecting with two nodes of the steel cable 2, and the tightening structure is used for tightening the position between the two nodes of the steel cable 2.
More specifically, referring to fig. 2 and 3, in the present embodiment, the tightening structure includes:
the support 51 is fixedly connected to the cross beam of the pipeline shared support 1;
the steel wire rope 2 is passed through the pulley 52 from the top of the pulley 52, then is threaded into and wound on the storage drum 53, and finally is fixed with the wheel wall of the storage drum 53.
Referring to fig. 2 again, since the steel cable 2 passes through the top of the pulley 52 in the one-side straight structure and passes through the top of the pulley 52 in the other-side straight structure again, and the pulleys 52 on both sides are located at the same point on the common support 1 for the respective pipes, two nodes of the steel cable 2 are defined by the two pulleys 52, that is, the nodes of the steel cable 2 are formed at the positions where the steel cable 2 passes through/out of the tops of the pulleys 52.
The pulley 52 structure can effectively avoid the implementation personnel from carrying out complicated positioning procedures when determining the same point on the common bracket 1 for the head and the tail pipelines, and has good application effect when in actual use.
In specific implementation, an operator can store/wind the steel wire rope 2 by rotating the storage drum 53, so as to tighten the position between two nodes of the steel wire rope 2.
It can be understood that: the storage reel 53 can rotate only when the first and the last sections of pipelines share the support 1, and when the rest of the pipelines share the support 1, the storage reel 53 is in a static state, so that the resistance between the storage reel and the steel wire rope 2 is preferably increased, and the steel wire rope 2 is prevented from being released accidentally.
Therefore, in this embodiment, the wheel wall of the storage drum 53 is provided with anti-slip threads to increase the frictional resistance between the storage drum and the steel wire rope 2.
Further, the storage drum 53 can adjust the length between the two nodes of the wire rope 2, and the operator can select to provide a damping structure on the storage drum 53 to lock the rotation of the storage drum 53.
In the embodiment, the steel cable 2 and the support 51 are locked by a locking structure, so as to fix the steel cable 2.
Specifically, referring to fig. 4, in the present embodiment, the present invention further includes a locking structure disposed between the pulley 52 and the storage drum 53, the locking structure includes a pair of friction plates disposed on the left and right sides of the steel wire rope 2, and the friction plates on the two sides are used for clamping and locking the steel wire rope 2 therebetween. The friction plates on the two sides generate friction force on the steel wire rope 2 between the friction plates and the steel wire rope 2, so that the steel wire rope 2 and the support 51 are in a relatively fixed state.
As described above, the locking structure is disassembled only when the two pipes at the head and the tail share the bracket 1, and the locking structure is locked at the rest of time. Therefore, as a preferred embodiment, in the present embodiment, the friction plates on both sides are a first friction plate 54 and a second friction plate 55, respectively, wherein the first friction plate 54 is fixedly attached to the outer wall of the support 51;
the bolt is characterized by further comprising a first bolt 56, wherein the threaded end of the first bolt penetrates through the second friction plate 55 and the first friction plate 54 in sequence and is inserted into the support 51, the first bolt 56 is in threaded connection with the support 51, and the head of the first bolt is abutted against the second friction plate 55.
The structural style can effectively guarantee the friction force borne by the steel wire rope 2, and when the friction force is insufficient, an operator only needs to screw the first bolt 56, so that the distance between the first friction plate 54 and the second friction plate 55 is reduced, and the friction force borne by the steel wire rope 2 can be adjusted.
More specifically, in the present embodiment, a receiving groove having a shape matched with that of the first friction plate 54 is formed on an outer wall of the support 51, and a first threaded hole for threaded connection with the first bolt 56 is formed in the receiving groove.
In addition, the first friction plate 54 and the second friction plate 55 are made of rubber.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
