It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 10 together, the cantilever according to the present invention will now be described. The cantilever frame comprises a wall connecting rod 1, a bearing plate 2, an accommodating piece 3, a support frame 6 and a cantilever belt 7.
The wall connecting rod 1 adopts a round rod structure with a round cross section and is used for penetrating through the outer wall of a building perpendicular to the wall surface; it should be noted that the penetrating mentioned here is only to describe the position and connection relationship between the wall connecting rod 1 and the wall surface, and in practical operation, a hole with a diameter larger than the diameter of the cross-section circle of the wall connecting rod 1 can be drilled on the wall surface, and the wall connecting rod 1 can be inserted through the hole to realize the connection mode penetrating through the wall surface.
The wall connecting rod 1 is provided with two ends, after the wall connecting rod 1 is connected with a building, the first end 14 of the wall connecting rod 1 is positioned outside the building, and the second end 15 of the wall connecting rod 1 is positioned inside the building; as shown in FIG. 2, a handle adapted to be manually grasped is attached to the second end 15 of the wall stud 1 to facilitate manual actuation of the wall stud 1 to move circumferentially about itself.
For convenience of description, in the present embodiment, the stud 1 is defined to be axially forward and rearward, and the first end 14 of the stud 1 is forward of the second end 15 of the stud 1.
The bearing plate 2 is used for being connected with the wall connecting rod 1 so as to be initially supported; the primary support mentioned here means that the carrier plate 2 can be released by the operator, but the carrier plate 2 cannot safely support the operator for operation.
The receiving member 3 is provided on the upper surface of the carrier plate 2, and specifically, in the present embodiment, the receiving member 3 is hinge-provided on the upper surface of the carrier plate 2, and the hinge axis is provided in the left-right direction.
The accommodating part 3 is provided with an accommodating cavity 31 and a belt body outlet 32, an extension belt 4 is arranged in the accommodating cavity 31, and the extension belt 4 can extend out of the accommodating part 3 through the belt body outlet 32. As shown in fig. 8, a rotating shaft is provided in the accommodating chamber 31, and the portion of the extension tape 4 in the accommodating chamber 31 is wound around the rotating shaft.
A locking structure 5 for connecting the accommodating part 3 and the extension belt 4 is arranged between the accommodating part 3 and the extension belt 4; in particular, the locking structure 5 has two states of use: firstly, the accommodating part 3 is connected with the extension belt 4, and the length of the extension belt 4 extending out of the accommodating part 3 is limited; secondly, the accommodating member 3 and the extension belt 4 are separated, and the length of the accommodating member 3 extending out of the accommodating member 3 can be adjusted according to the length of the accommodating member 3 extending into/out of the accommodating cavity 31.
The support frame 6 is used for being fixedly arranged on the outer wall of the building and is positioned above the wall connecting rod 1.
The overhanging belt 7 is erected on the support frame 6, wherein one end is fixedly connected with the extending end of the extending belt 4, and the other end is suitable for being connected with the bearing plate 2, so that the bearing plate 2 is fixedly supported. Wherein, the connection mode of encorbelmenting area 7 and extension area 4 is: the extending end of the extension belt 4 is connected with a lock catch 41, and the end surface of the cantilever belt 7, which is suitable for being connected with the extension belt 4, is provided with a connecting port suitable for being connected with the lock catch 41; the structure of the latch 41 is the same as that of the prior art, and is not described herein.
In the embodiment of the application, the bearing plate 2 is primarily supported by connecting the wall connecting rod 1 and the bearing plate 2; then, the extension length of the extension belt 4 is adjusted through the locking structure 5, so that when the overhanging belt 7 is erected on the support frame 6 and is connected with the bearing plate 2, the combined structure of the extension belt 4 and the overhanging belt 7 can be tightened, and the bearing plate 2 is fixedly supported.
In the above process, if the overhanging band 7 is too long, the partial extending band 4 is accommodated back into the accommodating cavity 31 in the accommodating piece 3; if the cantilever strap 7 is too short, part of the extension strap 4 is extended out of the receiving member 3 to ensure that the carrier plate 2 can be fixedly supported.
In summary, compared with the prior art, the cantilever frame provided by this embodiment can ensure that the overhanging belt 7 can make the bearing plate 2 obtain fixed support by adjusting the combined length of the overhanging belt 7 and the extension belt 4, so that the length range of the overhanging belt 7 is increased, the length requirement is reduced, the phenomenon that the bearing plate 2 cannot be smoothly fixed and supported due to the overlong or overlong overhanging belt 7 is avoided, and the installation efficiency of the overhanging belt 7 is ensured.
It should be added that the support frame 6 includes a support rod arranged horizontally and two connecting rods arranged at two ends of the support rod and extending along the front-back direction, the support rod is fixed on the outer wall of the building through the connecting rods, and the support rod and the two connecting rods form a door-shaped frame body structure suitable for hanging the overhanging belt 7.
When the overhanging belt 7 is erected on the support frame 6, the overhanging belt 7 cannot move along the left-right direction; the reasons for this are two reasons: firstly, both ends of the cantilever belt 7 are in a state of being connected with a stable plane, and the surface of the cantilever belt 7 is tightened so as not to move along the left and right directions; secondly, as shown in fig. 1, a plurality of holes are formed in the surface of the supporting rod and are arranged in the vertical direction, the holes are distributed at intervals in the left-right direction, and a limiting rod can be inserted into the holes to clamp the left side surface and the right side surface of the overhanging belt 7, so that the movement of the overhanging belt 7 in the left-right direction is limited.
In some embodiments, the above feature carrying plate 2 can be configured as shown in FIGS. 1 and 6. Referring to fig. 1 and 6, the bearing plate 2 is provided with a plug hole 21 penetrating in the front-rear direction, and the wall connecting rod 1 is adapted to be inserted into the plug hole 21, so that the bearing plate 2 is primarily supported.
By adopting the technical scheme, a worker outside a building can realize the connection of the bearing plate 2 and the wall connecting rod 1 only by aligning the plug-in hole 21 with the wall connecting rod 1 and moving the bearing plate 2 along the front-back direction, so that the bearing plate 2 is initially supported; the whole process is convenient for manual operation, and the installation efficiency of the cantilever frame provided by the embodiment is ensured.
It should be added that, in the foregoing, the diameter of the cross-section circle of the wall connecting rod 1 is smaller than the aperture of the hole previously punched on the wall surface, so that the wall connecting rod 1 can move in the front-back direction; that is, during actual installation, the movement of the bearing plate 2 in the up-down direction is limited, and the wall connecting rod 1 is moved in the front-back direction, so that the technical purpose that the wall connecting rod 1 is inserted into the inserting hole 21 to primarily support the bearing plate 2 can be achieved; in the actual assembly process, the method can be freely selected according to different field environments.
In some embodiments, the above-described features of the wall stud 1 may be configured as shown in fig. 3 and 4. Referring to fig. 3 and 4, a receiving groove 11 is formed on the outer peripheral wall of the first end 14 of the wall connecting rod 1, a swing arm 12 is arranged in the receiving groove 11, and the swing axial direction of the swing arm 12 is perpendicular to the axial direction of the wall connecting rod 1.
The swing arm 12 has a first swing position and a second swing position, as follows:
when the swing arm 12 is in the first swing position, the axial direction of the swing arm 12 is perpendicular to the axial direction of the wall connecting rod 1, the swing arm 12 extends out of the accommodating groove 11, and the extending part is suitable for being abutted against the front end face of the bearing plate 2 so as to limit the wall connecting rod 1 to move towards the rear;
when the swing arm 12 is in the second swing position, the axial direction of the swing arm 12 is parallel to the axial direction of the wall connecting rod 1, and the swing arm 12 is positioned in the accommodating groove 11;
a torsion spring 121 for driving the swing arm 12 to swing from the second swing position to the first swing position is arranged between the swing arm 12 and the wall connecting rod 1.
By adopting the technical scheme, the swing arm 12 can limit the relative movement of the wall connecting rod 1 and the bearing plate 2, so that the structural stability of the device is improved; in addition, the torsion spring 121 can ensure that the swing arm 12 is in the first swing position, which improves the reliability of the device in actual use.
In the process, when the swing arm 12 is in the first swing position, the swing arm 12 can be driven to swing from the first swing position to the second swing position in the process of moving the bearing plate 2 from front to back to connect the plug hole 21 with the wall connecting rod 1; under the same condition, however, the wall connecting rod 1 cannot be inserted into the inserting hole 21 by moving the wall connecting rod 1 from back to front; to address this problem, in some embodiments, the above-described feature of the wall bar 1 may be configured as shown in fig. 4 and 5. Referring to fig. 4 and 5, a threading hole 13 is formed in the end surface of the second end 15 of the wall connecting rod 1, and the threading hole 13 extends axially along the wall connecting rod 1 to be communicated with the accommodating groove 11.
The threading hole 13 is internally provided with a threading wire 131, one end of the threading wire 131 extends into the accommodating groove 11 and is connected with the swing arm 12, and the other end of the threading wire 131 extends out from the end face of the second end 15 of the wall connecting rod 1 through the threading hole 13.
By adopting the technical scheme, the staffs in the building can pull the stay wire 131 from front to back to drive the swing arm 12 to swing from the first swing position to the second swing position, so that the wall connecting rod 1 can be inserted into the insertion hole 21 by moving the wall connecting rod 1 from back to front, and the reliability of the device during assembly is improved.
It should be added that the part of the pulling wire 131 extending out of the end face of the second end 15 of the wall connecting rod 1 is connected with a plate body used for abutting against the end face of the second end 15 of the wall connecting rod 1, when the plate body abuts against the end face of the second end 15 of the wall connecting rod 1, the pulling wire 131 cannot completely enter the threading hole 13, and the structural stability of the device is ensured.
After long-term field work, the inventor finds that a lot of inconvenience still exists in the process of primarily supporting the bearing plate 2; for example, it takes a while for workers inside a building to receive messages and give feedback to workers outside the building, which also reduces the efficiency of the mounting of the cantilever; therefore, after a long time of research and development, the inventor makes further innovation, and the specific content is as follows: in some embodiments, the above feature carrying plate 2 can be configured as shown in FIG. 1. Referring to fig. 1, the carrying floor 2 is slidably provided with a connection portion 22 adapted to be connected to an outer wall of a building.
This connecting portion 22 is movable in the up-and-down direction with respect to the carrier plate 2, has a first relative position and a second relative position, and the first relative position is below the second relative position, specifically:
when the wall connecting rod 1 supports the bearing plate 2, the connecting part 22 can move downwards to a first relative position and is connected with the outer wall of the building;
when the connecting part 22 is in the first relative position and connected with the building, the wall connecting rod 1 can be separated from the bearing plate 2 by moving the wall connecting rod 1 from front to back, so that the bearing plate 2 loses support and moves downwards until the connecting part 22 is in the second relative position, at the moment, the wall connecting rod 1 and the plug hole 21 are in the coaxial position, and the wall connecting rod 1 can be inserted into the plug hole 21 by moving the wall connecting rod 1 from back to front again.
During actual assembly, a worker outside a building firstly places the bearing plate 2 on the wall connecting rod 1, adjusts the connecting part 22 at the moment to enable the connecting part 22 to be in a first relative position, and then connects the connecting part 22 with the outer wall of the building (the seat body is installed on the outer wall of the building, which belongs to the prior art, so that the specific connection mode is not limited herein); afterwards, the staff in the demonstration building pulls even wall pole 1 from the front and back alright make connecting portion 22 lose the support to move to the second relative position from first relative position, then the staff in the building pushes even wall pole 1 from the back and forward can make even wall pole 1 insert spliced eye 21, thereby makes loading board 2 obtain preliminary support, and because connecting portion 22 meets with the building outer wall, therefore this preliminary supporting effect is better.
By adopting the technical scheme, the carrying plate 2 is placed on the wall connecting rod 1 by a worker outside the building, the connecting part 22 is connected with the outer wall of the building, and the rest work can be replaced by the worker inside the building; the process that workers outside the building wait for feedback of the workers inside the building is avoided, and the efficiency of the device in actual use is ensured.
It should be noted that the time for installing the connection portion 22 on the outer wall of the building is short, and the time for connecting the connection portion 22 with the outer wall of the building is substantially negligible compared to the information communication between the inside and the outside of the building.
It should be noted that the surface of the connecting portion 22 facing the bearing plate 2 is provided with a slider, and the bearing plate 2 is provided with a slide rail suitable for embedding the slider; when the connecting part 22 is at the first relative position, the lower surface of the slide block of the connecting part 22 is connected with the lower surface of the slide way; when the connecting part 22 is at the second relative position, the upper surface of the slide block of the connecting part 22 is connected with the upper surface of the slide way; according to this feature, it is ensured that the connecting portion 22 can be moved to the second relative position after the connecting portion 22 loses its support.
In some embodiments, the above feature carrier plate 2 can be configured as shown in FIG. 6. Referring to fig. 6, the bottom surface of the carrier plate 2 is provided with an engagement groove 23, and the engagement groove 23 extends in the front-rear direction to penetrate the front and rear end surfaces of the carrier plate 2.
When the connecting part 22 is in the first relative position, the wall connecting rod 1 engages in the engagement groove 23 and contacts the groove bottom of the engagement groove 23.
Through adopting above-mentioned technical scheme, even behind the scarf groove 23 of wall pole 1 embedding, just can restrict the removal of loading board 2 along left and right sides direction, improved the structural stability of this device.
