Problems solved by technology

[0002] At present, the Ministry of Housing and Urban-Rural Development of my country is vigorously promoting tool-type scaffolding and popularizing it in construction projects. Conventional types such as bowl-buckle scaffolding, disc-buckle scaffolding, wheel-buckle scaffolding, and keyway scaffolding are often used. They are in When dealing with irregular or non-modular building structure planes, because of the fixed length and modulus of the horizontal rods, the horizontal and vertical distances of the plane layout are limited, so that the plane coverage of the frame often leaves dead angles and the coverage is not in place.
The usual practice is to use steel pipe scaffolding with fasteners to erect non-modular parts, which results in the mixed erection of different systems, which is prone to safety hazards. At the same time, the applicability design of the frame also consumes labor and affects the construction progress, resulting in a large comprehensive economic loss.

Embodiment 1

[0033] Example 1, such as figure 2 and image 3 As shown, when the multi-stage stepless telescopic horizontal rod is in the first gear state, the outer sleeve, inner sleeve, and straight thread stepless adjustment rod are in the original state, the outer sleeve is outside the inner sleeve, and the fixing pin is set on the left side In the first pin hole of the outer casing and the pin hole of the inner casing, at this time, the length of the multi-stage stepless telescopic horizontal rod in the first gear state is the length of the outer casing or the inner casing, which is 300mm (including 50mm+250mm ); in the state of the first gear, rotate and adjust the length of the straight thread stepless adjustment rod in the inner casing within the range of 0mm-100mm to form the stepless adjustment state of the first gear, in the stepless adjustment state of the first gear At least keep the length of the straight-threaded stepless adjustment rod inserted into the inner sleeve to be ...

Embodiment 2

[0034] Example 2, such as Figure 4 and Figure 5 As shown, when the multi-stage stepless telescopic horizontal rod is in the second gear state, the outer casing is outside the inner casing, and the fixing pin is arranged in the second outer casing pin hole and the inner casing pin hole on the left. , the length of the multi-stage stepless telescopic horizontal bar in the second gear state is the length of the outer casing plus the distance moved by a pin hole of the outer casing, which is 300mm (including 150mm+150mm)+100mm=400mm; in the second gear state , rotate and adjust the length of the straight thread stepless adjustment rod in the inner sleeve to the range of 0mm-100mm to form the second gear stepless adjustment state, and at least keep the straight thread stepless adjustment rod in the second gear stepless adjustment state The length inserted into the inner casing is 20 mm to meet the anchoring strength requirements so that the rods can reach the required working le...

Embodiment 3

[0035] Example 3, such as Figure 6 and Figure 7As shown, when the multi-stage stepless telescopic horizontal rod is in the third gear state, the outer casing is outside the inner casing, and the fixing pin is set in the third outer casing pin hole and the inner casing pin hole on the left. , the length of the multi-stage stepless telescopic horizontal rod in the third gear state is the length of the outer casing plus the distance of two outer casing pin holes, which is 300mm (including 250mm+50mm)+200mm=500mm; in the third gear state, rotate and adjust the length of the straight thread stepless adjustment rod in the inner casing within the range of 0mm-100mm to form the third gear stepless adjustment state, and at least maintain the straight thread stepless adjustment state in the third gear stepless adjustment state The length of the rod inserted into the inner casing is 20 mm to meet the anchoring strength requirements so that the rod reaches the required working length a...

Abstract

The invention discloses a multi-section stepless telescopic horizontal rod and method. The multi-section stepless telescopic horizontal rod comprises an outer sleeve, an inner sleeve, a straight thread stepless adjusting rod and a fixing pin, the outer sleeve and the inner sleeve are the same in length, the inner sleeve is sleeved with the outer sleeve, the inner diameter of the outer sleeve is larger than the outer diameter of the inner sleeve, the length of the inner sleeve is larger than that of the straight thread stepless adjusting rod, internal threads consistent with the thread steplessadjusting rod in length are formed in the inner wall of the inner sleeve and inwards formed from one end of the inner sleeve, external threads are formed in the whole body of the outer wall of the straight thread stepless adjusting rod, and the straight thread stepless adjusting rod is arranged in the inner sleeve in a threaded connection mode; and outer sleeve pin holes are formed in the wall body of the outer sleeve, and fixing pins are arranged on corresponding outer sleeve pin holes and corresponding inner sleeve pin holes. The product can effectively solve the problem of plane arrangement of a scaffold body in time, avoids the technical problem that plane coverage of the scaffold body is not in place, reduces construction cost and construction potential safety hazards, and accelerates construction efficiency.

Description

technical field [0001] The invention relates to the technical field of building construction scaffolding, in particular to a multi-stage stepless telescopic horizontal rod and a method thereof. Background technique [0002] At present, the Ministry of Housing and Urban-Rural Development of my country is vigorously promoting tool-type scaffolding and popularizing it in construction projects. Conventional types such as bowl-buckle scaffolding, disc-buckle scaffolding, wheel-buckle scaffolding, and keyway scaffolding are often used. They are in When dealing with building structure planes with irregular or non-modular bay sizes, because the length and modulus of the horizontal rods are fixed, the horizontal and vertical distances of the plane layout are limited, so that the plane coverage of the frame often leaves dead angles and the coverage is not in place. The usual practice is to use steel pipe scaffolding with fasteners to erect non-modular parts, which results in the mixed ...
