Technical Field

[0001] The utility model relates to the technical field of building exterior wall connection equipment, in particular to a building exterior scaffolding wall connection piece. Background Art

[0002] Looking at the wall connecting parts used in the erection of external wall scaffolding in recent years, most of them adopt the form of pre-embedded short steel pipes in the cast-in-place concrete structure, that is, the short steel pipes are vertically embedded in the concrete of the side beam, and part of them are exposed. Then, horizontal connecting rods (scaffolding steel pipes) are added and fasteners are used to connect the external frame uprights with the embedded steel pipes. However, the traditional method has many shortcomings, which has caused many adverse effects on project quality and construction safety.

[0003] The existing construction method has been changed to use small wall ties for connection, but small wall ties also have certain problems during use. Due to the reduced size of the wall ties, their own strength may be reduced. At the same time, when installing the wall ties, the wall ties need to be pre-fixed on the wooden formwork, and then the steel pipes are fixed to the wall ties after pouring. Since the existing wall ties are used separately, when fixing the steel pipes to the wall ties, one steel pipe of the scaffolding is usually fixed to one wall tie. Not only does it have high requirements on the structural strength of the wall ties, but the steel pipes are easy to rotate relative to the wall ties, causing the scaffolding to become unstable, which poses a safety hazard during the construction process.

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 6 The utility model provides a technical solution: a building external scaffolding wall connecting piece, comprising an embedded part 1, the embedded part 1 is used to be embedded in the interior of the supporting wall, and a threaded section is provided in the embedded part 1.

[0026] The first connecting component can be connected to the embedded part 1 and is used to fix the embedded part 1 relative to the wooden formwork 11 so that the embedded part 1 can be embedded in the supporting wall 3 when pouring the supporting wall 3.

[0027] The second connecting assembly includes a connecting portion 2 and a fixing mechanism connecting the embedded portion 1 and the connecting portion 2. The connecting portion 2 is used to fix the scaffolding steel pipe. The fixing mechanisms are symmetrically arranged in groups of two.

[0028] A connecting plate 4 is provided on the outside of the embedded part 1 for connecting adjacent embedded parts 1 . An annular connecting groove 5 is provided on the outer circumferential surface of the embedded part 1 . A clamping groove 6 matching the annular connecting groove 5 is provided on both sides of the connecting plate 4 .

[0029] When in use, the embedded part 1 can be fixed on the wooden formwork 11 through the first connecting component. According to the spacing between the embedded parts 1, a connecting plate 4 of appropriate size is selected, and the card slot 6 on the connecting plate 4 is clamped together with the annular connecting groove 5 on the embedded part 1 to connect adjacent embedded parts 1 together to improve the overall strength. Two annular connecting grooves 5 are provided on the embedded part 1. When in use, the number of embedded parts 1 connected together can be adjusted according to specific circumstances. After the embedded part 1 is fixed on the wooden formwork 11, it is poured. After the pouring is completed, the embedded part 1 remains in the concrete. At this time, the scaffolding steel pipe can be clamped and fixed by the connecting part 2, and the connecting part 2 and the embedded part 1 are fixed together by the fixing mechanism. The fixing mechanism is symmetrically arranged on both sides of the connecting part 2, which is more firm when fixed and reduces the possibility of shaking of the scaffolding steel pipe.

[0030] In this embodiment, as a preferred solution, the threaded section is a square nut 7 , and the square nut 7 is arranged at an end of the embedded part 1 away from the wooden template 11 .

[0031] The square nut 7 is clamped with the inner wall of the embedded part 1. During the process of connecting with the external thread, the outer shell of the embedded part 1 can limit the square nut 7, preventing the square nut 7 from rotating together with the external thread, so that the external thread can be threadedly connected with the square nut 7.

[0032] In this embodiment, as a preferred solution, the first connecting component includes a threaded rod 8, a gasket 9 and a fixing nut 10. The threaded rod 8 penetrates into the interior of the embedded part 1 and is threadedly connected to the square nut 7. The gasket 9 and the fixing nut 10 are both arranged at the end of the threaded rod 8 away from the square nut 7. The fixing nut 10 is threadedly connected to the threaded rod 8. The fixing nut 10 is used to squeeze the wooden formwork 11 relative to the embedded part 1 so that when the supporting wall 3 is cast, the embedded part 1 of the wall connecting member can be fixedly cast in the supporting wall 3.

[0033] When fixing the embedded part 1, the threaded rod 8 is inserted into the embedded part 1, and the threaded rod 8 is threadedly connected to the square nut 7 in the embedded part 1. The length of the threaded rod 8 is greater than the length of the embedded part 1. After the threaded rod 8 and the square nut 7 are threaded together, the other end of the threaded rod 8 will remain outside the embedded part 1, and the fixing nut 10 can be threadedly connected to the threaded rod 8 remaining outside. When in use, the fixing nut 10, the threaded rod 8 and the embedded part 1 cooperate to fix the embedded part 1 on the wooden formwork 11, so that the embedded part 1 is not easy to shake during pouring.

[0034] In this embodiment, as a preferred solution, the fixing mechanism includes a connecting ear 12 arranged on the outer circular surface of the connecting part 2 and a fixing screw 13 passing through the connecting ear 12. The fixing screw 13 is threadedly connected to the square nut 7 to fix the scaffolding steel pipe through the connecting part 2, and one end of the steel pipe is pressed against the surface of the supporting wall 3.

[0035] The fixing screw 13 can also be threadedly connected with the square nut 7. After the embedded part 1 is poured into the concrete and the threaded rod 8 is taken out, the fixing screw 13 can be screwed into the square nut 7 to fix the connecting part 2 to the outside of the embedded part 1. After the connecting part 2 and the steel pipe are fixed, the connecting part 2 and the embedded part 1 are fixed together, so that the steel pipe in the connecting part 2 can be firmly fixed to the wall. At the same time, the fixing mechanism is arranged on both sides of the connecting part 2, which is more stable when fixing to prevent the connecting part 2 from rotating due to the use of a single embedded part 1.

[0036] In this embodiment, as a preferred solution, the connecting part 2 includes a clamping end 14 and a movable end 15, so that the clamping end 14 and the movable end 15 cooperate to tighten the steel pipe, and one end of the fixed end and the movable end 15 are connected by a hinge, and the other end is detachably connected by a bolt.

[0037] The clamping end 14 and the movable end 15 can rotate around a hinge to facilitate clamping the steel pipe. After the steel pipe is clamped, the bolts can be rotated to fix the two together, thereby fixing the position of the internal steel pipe. The clamping end 14 and the movable end 15 can rotate around a hinge to facilitate clamping the steel pipe. After the steel pipe is clamped, the bolts can be rotated to fix the two together, thereby fixing the position of the internal steel pipe.

[0038] In this embodiment, as a preferred solution, protrusions 16 are provided inside the clamping end 14 and the movable end 15 , and the protrusions 16 press against the outer circumferential surface of the steel pipe to clamp the steel pipe.

[0039] The protrusion 16 can press against the outer circumferential surface of the steel pipe, providing greater downward pressure during clamping, so that the connection part 2 and the steel pipe are fixed more firmly and less likely to shake.

[0040] In the present invention, the working steps of the device are as follows:

[0041] 1. When in use, insert the threaded rod 8 into the embedded part 1, and connect the thread at one end to the square nut 7 in the embedded part 1. After the connection is completed, pass the exposed end of the threaded rod 8 through the wooden template 11 and use the fixing nut 10 to fix the position of the embedded part 1;

[0042] 2. Select a connecting plate 4 of appropriate size according to actual needs, buckle the slot 6 at one end of the connecting plate 4 into the annular connecting groove 5 on the embedded part 1, and connect the adjacent embedded parts 1 together. After the connection is completed, pour the embedded parts 1 into the concrete;

[0043] 3. After pouring is completed, remove the fixing nut 10 and the wooden formwork 11, and at the same time take out the internal threaded rod 8, use the connecting part 2 to clamp and fix the steel pipe, after fixing the steel pipe, place one end of the steel pipe against the wall, use the fixing screw 13 to pass through the connecting ears 12 on both sides of the connecting part 2, and insert the fixing screw 13 into the embedded part 1, so that the fixing screw 13 and the square nut 7 are threaded together to fix the position of the steel pipe.
