Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a jacking device for a slope roof. Background Art

[0002] During the construction of the roof of a large venue, it is usually necessary to build a support frame to support the roof structure. For the main keel of the roof, it is generally necessary to use a top support to support it. However, since the roofs of large venues are mostly irregular curved structures, and the main keel is usually square, during the roof construction process, after the frame is built, in order to ensure that the main keel fits the roof panel, it is necessary to install wooden wedges on the top support to adjust the inclination of the main keel according to the inclination of the roof panel to adapt to the inclination of the roof panel.

[0003] However, this adjustment method will lead to an increase in construction volume and a decrease in construction efficiency, and the subsequent addition of wooden wedges requires high-altitude operations, which poses a major safety hazard. Utility Model Content

[0004] To this end, the utility model provides a jacking device for a sloping roof, which mainly solves the problem that the jacking device of the prior art cannot adapt to the inclination of the roof panel and needs to install wooden wedges, which leads to increased construction workload, reduced construction efficiency and greater safety hazards.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A jacking device for a sloping roof comprises a first supporting column; the top of the first supporting column is threadedly connected to a second supporting column along its axial direction; the top of the second supporting column is hingedly connected to an adjustable placement portion; a U-shaped placement seat is provided on the top of the adjustable placement portion for placing a main keel; and a tightening device is also included for locking or loosening the adjustable placement portion and the second supporting column.

[0007] Optionally, the tensioning device includes a T-shaped tensioning rod; a forward thread is provided on the left outer wall of the tensioning rod, and a reverse thread is provided on the right outer wall; a first clamping portion is provided on the left side of the bottom of the adjustment placement portion, and a second clamping portion is provided on the right side; a clamping groove is formed between the first clamping portion and the second clamping portion; a connecting head adapted to the clamping groove is provided on the top of the second support column; the connecting head is embedded in the clamping groove, and the tensioning rod can movably pass through the connecting head, be connected to the first clamping portion with a forward thread, and be connected to the second clamping portion with a reverse thread, and the tensioning rod is rotated, and under the action of the forward and reverse threads, the first clamping portion and the second clamping portion clamp or loosen the connecting head.

[0008] Preferably, a handle is provided on the left side of the elastic rod.

[0009] Optionally, an internal threaded hole is formed on the top surface of the first support column along its axial direction; an external thread is formed on the outer wall of the second support column; and the second support column is threadedly connected to the internal threaded hole of the first support column.

[0010] Preferably, a raised circular support platform is provided on the top outer wall of the first support column; at least three ribs connected to the outer wall of the first support column are evenly distributed along the radial direction on the top or bottom surface of the circular support platform.

[0011] The utility model has at least the following beneficial effects:

[0012] It is provided with a first support column, the top of the first support column is connected to the second support column by a thread along its axial direction, the top of the second support column is hinged with an adjustable placement part, the top of the adjustable placement part is provided with a placement seat, and a loosening device is also provided to lock or loosen the adjustable placement part and the second support column. In this way, when setting the top support at the desired location, the height required by the pre-designed scheme and the angle of inclination of the main keel can be determined by rotating the first support column and the second support column. Since the first support column and the second support column are threadedly connected, the length between them can be adjusted left and right by the thread to meet the height requirement; at the same time, the adjustable placement part is hinged at the top of the second support column, and the inclination of the placement seat can be adjusted by rotating the adjustable placement part, so that the main keel placed thereon meets the inclination requirement; in this way, it is not necessary to install wooden wedges after the frame is built, which reduces the workload and improves the construction efficiency.

[0013] It can be seen that the jacking device for a sloped roof of the utility model has the advantages of simple structure, easy operation, reduced workload, improved construction efficiency, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0023] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0024] The terms such as "upper", "lower", "left", "right", "middle", etc. used in this application are usually used to facilitate intuitive understanding by comparing with the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.
