Detailed Description

Ventilating ducts, hydroelectric bridges and the like of modern buildings are mostly required to be installed on floor slabs at the tops of floors. In order to effectively fix these pipes, a fixing bracket is often formed using a hanger bar 1' as shown in fig. 1. Through careful observation and analysis, the inventor found that the risk of safety accidents such as falling off of the hanger rod 1' in the fixing bracket gradually increases with the increase of the usage amount of the fixing bracket. In the practical application process, because constructors do not pay attention to the safety accidents, such as falling of the suspender 1' in the fixed support and the like, and the inspection and acceptance of the whole number cannot be realized due to the inspection and acceptance of a construction site, the safety accidents are happened occasionally.

In addition, because the expansion bolts are fixed on the floor slab, the floor slab bears the load action of air-conditioning air pipes, hydroelectric bridges and the like. The acting force of the loads on the floor slab is long in time and wide in acting range, the floor slab structure is easy to creep, the deformation of the floor slab structure is caused, cracks in the floor slab are enlarged, gravity in the floor slab structure is redistributed, the bearing capacity of the floor slab is weakened finally, and the danger coefficient of the building is increased. The problem of fixed mounting of the fixed bracket is therefore increasingly emphasized.

The inventors have conducted a careful study with respect to the problem of the prior art in which the fixing bracket comes off. It has been found through research that the fixing bracket widely used at present comprises two suspension rods fixed on the floor, and a keel for connecting the two suspension rods. The hanger bar is fixed to the floor by using expansion bolts driven into the floor to provide an adhesive force, and the expansion bolts are perpendicular to the floor. The stress direction of the hanger rod is parallel to the length direction of the expansion bolt and is also vertical to the floor slab. Because expansion bolts mainly rely on the frictional force between bolt and the floor concrete to reach fixed effect, under the effect that exists the load for a long time, even if receive less vibration under long-term atress, also take place to drop when also easy between expansion bolts and the floor. Or when the load on the suspender suddenly increases or an earthquake is met, the risk of falling off of the suspender is also increased.

Based on the analysis content, the inventor provides a scheme capable of improving the adhesion force of the suspender through continuous exploration, and the fixing support implemented by the scheme can avoid the creep phenomenon of a floor slab structure to a greater extent and can ensure that the suspender does not have the risk of falling.

The hanger rod for fixing the pipeline and the ceiling provided by the invention is further described in detail with reference to the attached drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following claims and description. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

The present embodiment provides a suspension rod for a pipe and ceiling fixing bracket, as shown in fig. 2 and 3. Fig. 2 is a schematic view of a boom structure fixed to a frame beam according to this embodiment. Fig. 3 is a schematic structural view of a fixing bracket formed by the suspension rod and the keel provided by the embodiment. This hanger bar 1 comprises a fixing anchor 11 fixed to the side of a frame beam 200 in a building and a rod member 12 in a vertical state. A connecting element 13 is also provided between the rod 12 and the fixing anchor 11 for connecting one end of the rod 12 to the fixing anchor 11, and the rod 12 extends in a direction perpendicular to the fixing anchor 11. Of course, the other end of the rod member 12 is used for connecting the keel 2 in the fixing bracket 100, i.e., the fixing bracket 100 in fig. 2 is formed by the combination of two hanger bars 1 and one keel 2.

Just because the installation position of the hanger rod is transferred to the frame beam from the floor, the influence of the hanger rod on the floor under the stress action is reduced, and the risk of causing the floor to creep is reduced.

In order to more intuitively explain the suspension rod 1 provided in the present embodiment, the present embodiment also provides a preferable, more specific and easily implemented solution to describe the suspension rod 1.

With continued reference to fig. 2 and 3, the rod 1 is a cylindrical straight rod, which is convenient for processing and easy for obtaining materials. The diameter of the rod 12 can be selected from the common sizes such as 8mm and 10mm, and can also be selected according to specific construction requirements. Also because of the threads provided at the other end of the bar 12, the keel 2 can be conveniently secured by means of the threads and nuts. Because the scheme provided by the embodiment mainly relates to the suspension rod 1, the keel 2 used for forming the fixing support can still adopt the existing keel 2 formed by angle steel. Such a keel 2 can be conveniently perforated at both ends thereof to allow the other end of the rod 12 to pass through, and finally the connection of the keel 2 to the rod 12 is achieved by means of threads and nuts.

Next, in order to easily manufacture the connecting member 13 capable of vertically connecting the rod 12 and the fixing anchor 11, the connecting member 13 is manufactured by using angle steel in the present embodiment. The purpose of selecting the angle steel is that the angle steel can meet the functional requirements of the connecting piece 13 on one hand, and the effect of vertically connecting the fixed anchor bolt 11 and the rod piece 12 is achieved; on the other hand, the angle steel material is easy to obtain, low in price and easy to process. And when the rod 12 is also made of steel, the rod 12 and the connecting piece 13 can be quickly connected together by welding, so that the manufacturing efficiency is further improved, and the manufacturing cost is reduced.

When the connecting member 13 is formed of angle steel (for example, ∟ 30 x 3 equal angle steel is used), the portion of the rod member 12 near one end thereof can be fixed to the inner side of the dorsal limb of the connecting member 13 and brought into contact with the plane of the two perpendicular sides of the connecting member 13, as described above, just like the connecting pattern of the connecting member 13 and the rod member 12 in fig. 4, which is formed by welding.

Actually, the connecting member 13 made of angle steel has high strength, so in order to save materials and further reduce the manufacturing cost, the length of the connecting member 13 made of angle steel can be 50mm at the minimum.

Also, in order to facilitate the connection of the connecting member 13 with the rod 12 and to smoothly bring the rod 12 into a perpendicular state with respect to the fixing anchor 11, the extending direction of the rod 12 may be parallel to the extending direction of the connecting member 13. The connection form of the rod 12 and the connecting piece 13 in fig. 4 is reasonable, firm and convenient to manufacture.

The function of the connecting element is to connect the rod 12 and the fixing anchor 11. The connecting element 13 also takes into account how to facilitate the connection of the fixing anchor 11. For this purpose, the embodiment is based on the angle steel and the fixing anchor 11 itself, and a through hole 131 is provided in the connecting part 13, and this through hole 131 can be used to pass through the fixing anchor 11, and this through hole 131 is located on the plane of one of the sides of the angle steel, as shown in fig. 4, in order to finally form the fixing anchor 11 passing through the through hole 131 into a form perpendicular to the rod 12. I.e. in the form of the structure shown in fig. 2.

In order to facilitate the fixing of the fixing anchor 11 to the frame beam of the building, said fixing anchor can be implemented as an expansion bolt. The installation of the anchor bolts 11 on the frame beam 200 can be easily performed by drilling holes in the frame beam 200 and screwing in expansion bolts. Of course, the position of the fixing anchor 11 is not set randomly, and multiple times of stress analysis show that when the distance between the installation position of the fixing anchor 11 and the bottom surface of the frame beam 200 is in the range of one third to two thirds of the height a of the frame beam (see fig. 2), the stress is more balanced and stable, and the influence on the frame beam is less.

It should be noted that the building floor is not covered with the frame beams everywhere, so that in the actual construction process of the fixing bracket 100, the distance between the fixing brackets 200 can be reasonably adjusted and set according to the distribution positions of the frame beams 200, for example, when the diameter or the longest side length of the horizontally installed ventilation pipe is less than 400mm, the distance between the fixing brackets should not be more than 4 m; when the diameter or longest side of the vent pipe is larger than 400mm, the distance between the fixing brackets should not be larger than 3 m. Of course, the distance division can be performed according to other specific construction requirements, and the details are not repeated herein. The purpose of the reasonable distance is to make more suspension rods 1 in the fixing support 100 to be installed by the solution provided by this embodiment. If the position where the fixing bracket is required to be installed is met, but the frame beam 200 is not provided, the installation can be carried out by adopting a common suspender in the prior art appropriately. Thus, the hanger rod 1 mounted on the frame beam 200 and the ordinary hanger rod are mixed for use, and it is easy to understand that although the hanger rod 1 provided in this embodiment is only partially used, the mixed construction scheme can also greatly reduce the falling risk of the fixing bracket 100 and reduce the influence on the floor.

In conclusion, the utility model provides a about jib 1 scheme for pipeline, furred ceiling fixed bolster that this embodiment provided is through the fixed position that changes jib 1 to set up member 12 and fixed crab-bolt 11 in the jib 1 to mutually perpendicular's state, make fixed crab-bolt 11 when receiving vertical direction's external force, can be more firm fix the mounted position, full play self intensity effect has improved jib 1's bearing capacity, has reduced jib 1 to floor structure's influence.
