Embodiment Construction
[0023] Examples of lead screw cross locks, such as Figure 1-5 As shown, the lead screw cross lock includes a threaded sleeve 11 and a pressing device arranged outside the screwed sleeve 11 .
[0024] The threaded sleeve 11 is used for thread assembly on the screw rod 12 of the scaffolding support assembly. After being assembled on the screw rod 12, the height position of the screw sleeve can be adjusted by rotating the screw sleeve 11. In this embodiment, the middle section of the screw sleeve 11 The aperture of the hole is larger than the apertures at the two ends, and the threads are arranged at the two ends of the screw sleeve. In order to assemble the pressing device, two mounting seats are also provided on the screw sleeve 11, and the mounting seats are respectively located at the two ends of the screw sleeve and are arranged oppositely. 13 is set on the screw sleeve 11 through the corresponding boss 14, and a through groove is formed between the bosses where the two hi...

The invention relates to the field of building scaffolds, in particular to a lead screw cross-shaped lock catch part and a scaffold jacking assembly with the lock catch part. The lead screw cross-shaped lock catch part comprises thread sleeves used for being assembled on corresponding screws of the scaffold jacking assembly in a threaded mode. Pressing devices used for pressing corresponding scaffold cross bars to the thread sleeves are arranged outside the thread sleeves. Due to the fact that the thread sleeves of the lead screw cross-shaped lock catch part can be used for being assembled on the corresponding screws of the scaffold jacking assembly in the threaded mode and the pressing devices for pressing the corresponding scaffold cross bars to the thread sleeves are arranged outside the thread sleeves, in the using process, the thread sleeves can be assembled on the screws of the scaffold jacking assembly, the scaffold cross bars are arranged between the screws, the distance between a jacking supporting plate and the scaffold cross bar closest to the supporting plate can be adjusted on site according to requirements without changing the length of scaffold supporting steel pipes, and the problem that an existing jacking assembly is inconvenient to use is solved accordingly.
Description
technical field [0001] The invention relates to the field of construction scaffolding, in particular to a lead screw cross lock fastener and a scaffold jacking assembly using the fastener. Background technique [0002] Jacking brackets are often used in the process of building formwork construction, house decoration and decoration. The role of the jacking brackets is to support the supporting keel composed of single steel pipes or double steel pipes. [0003] The Chinese patent with the notification number CN203640322U and the announcement date of June 11, 2014 discloses a supporting jacking bracket, which is a relatively common jacking bracket, which includes a screw rod, a supporting plate and an adjusting nut, and the supporting plate It is fixed on the upper end of the screw rod, and the adjusting nut thread is assembled on the screw rod. When in use, insert the lower end of the screw rod into the corresponding supporting steel pipe, cooperate with the mouth edge of the ...
