[0004] 2. In the erection of building construction formwork supports, due to the fixed height position of the socket, the bottom form support of components such as beams must be constructed in cooperation with a coupler scaffold. Only using one type of scaffold, the socket-type scaffold, cannot complete the construction of building formwork erection.

Detailed implementation manners

[0039] The following further elaborates on the present invention in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0040] It should be understood that terms such as "having", "including", and "comprising" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0041] Such asFigures 1 - 12 As shown in the figure, the present invention provides an adjustable-height socket device for a socketed scaffolding, comprising: a height-adjusting vertical pipe 1, a height-adjusting socket 2, a connecting cross bar 3, and a pin piece 4; an outer sleeve thread is provided on the outer wall of the height-adjusting vertical pipe 1, an inner sleeve thread is provided on the inner wall of the height-adjusting socket 2, the height-adjusting socket 2 is sleeved on the outer wall of the height-adjusting vertical pipe 1, and the height-adjusting socket 2 is movably connected to the height-adjusting vertical pipe 1 through the cooperation of the inner sleeve thread and the outer sleeve thread. The end of the connecting cross bar 3 is connected to the connecting plate 6 on the outer wall of the height-adjusting socket 2 through the pin piece 4.

[0042] Working principle and beneficial effects of the above technical solution: The present invention achieves the function of adjusting the height of the height-adjusting socket 2 through the cooperation between the outer sleeve thread of the height-adjusting vertical pipe 1 and the inner sleeve thread of the height-adjusting socket 2. After adjusting the relative position of the height-adjusting socket 2 on the height-adjusting vertical pipe 1, the end of the connecting cross bar 3 is inserted into the connecting plate 6 of the height-adjusting socket 2, and then the pin piece 4 is inserted, so that the end of the connecting cross bar 3 is pin-connected to the connecting plate 6.

[0043] Through the design of the above structure, the defect that the height of the height-adjusting socket 2 is fixed is overcome, and the use range of the socketed scaffold is expanded and improved. Furthermore, the disadvantage that the bottom formwork of the beam must be matched with a fastener-type scaffolding in building construction is solved, and the building construction work of formwork support for all bottom plates and bottom beams of the slab can be completed by using only the socketed scaffold alone. At the same time, the construction efficiency of formwork support for the bottom formwork of the beam is improved. The device of the present invention has a simple principle, is easy to process, operate, and has a very high construction application efficiency. And it can also be used in combination with the existing socketed scaffold.

[0044] In one embodiment, connection ends are provided at both the top and bottom of the height-adjusting vertical pipe 1. The top of the height-adjusting vertical pipe 1 is connected to a standard top support member through the connection end, and the bottom of the height-adjusting vertical pipe 1 is connected to a standard vertical pipe through the connection end. The outer sleeve thread of the height-adjusting vertical pipe 1 is adapted to the inner sleeve thread of the height-adjusting socket 2. The outer sleeve thread is an external thread, and the inner sleeve thread is an internal thread.

[0045] The first implementation manner of the height-adjusting socket 2 is: the height-adjusting socket 2 includes the connecting plate 6 and an adjusting pipe 7. The connecting plate 6 is sleeved on the outer wall of the adjusting pipe 7. The inner wall of the adjusting pipe 7 is provided with an inner sleeve thread adapted to the outer sleeve thread of the height-adjusting vertical pipe 1. The adjusting pipe 7 is movably connected to the height-adjusting vertical pipe 1 through the cooperation of the inner sleeve thread and the outer sleeve thread.

[0046] Working principle and beneficial effects of the above technical solution: The outer sleeve thread of the height-adjusting vertical pipe 1 and the inner sleeve thread of the height-adjusting socket 2 can adopt a threaded connection method, that is, the height of the height-adjusting socket 2 can be adjusted through the thread screw. By rotating the height-adjusting socket 2 on the height-adjusting vertical pipe 1, the function of height adjustment can be achieved. Other cooperation methods can also be adopted, such as Figure 5The horizontal lines shown are fixedly connected by inner and outer sleeve threads. In the present invention, two implementation methods of height-adjusting the disc buckle 2 are provided.

[0047] In the first embodiment of the height adjustment disc 2, the height adjustment disc 2 is composed of a connecting disc 6 and an adjusting tube 7. An inner sleeve thread is arranged on the inner wall of the adjusting tube 7. Since the sleeve-type height adjustment disc 2 is adopted, the outer sleeve thread of the height adjustment riser 1 is protruding, so that the inner sleeve thread of the adjusting tube 7 is connected with the outer sleeve thread. Taking the threaded connection as an example, the outer sleeve thread of the height adjustment riser 1 is an outer thread, and the inner sleeve thread of the adjusting tube 7 is an inner thread. After the adjusting tube 7 is sleeved on the height adjustment riser 1, the connecting disc 6 is rotated to move the height adjustment disc 2 up and down for position adjustment. When the height is adjusted to a suitable height, the rotation is stopped. In this way, the height adjustment of the height adjustment disc 2 can be achieved.

[0048] In one embodiment, thread grooves are provided at both ends of the inner wall of the height adjusting disc buckle 2, the thread groove is conical, and the diameter close to the end of the height adjusting disc buckle 2 is larger than the diameter inside the height adjusting disc buckle 2, and an adaptable screw sleeve 5 is provided at the bottom of the height adjusting disc buckle 2, and one end of the adaptable screw sleeve 5 is conical to adapt to the thread groove.

[0049] The first implementation of the adaptable screw sleeve 5 is as follows: an inner thread adapted to the outer thread of the height-adjusting riser 1 is provided on the inner wall of the adaptable screw sleeve 5, the outer wall of the adaptable screw sleeve 5 is threadedly connected to the thread groove, and the adaptable screw sleeve 5 is composed of two adapted half-tubes.

[0050] A second embodiment of the adaptive screw sleeve 5 is as follows: a buckling tube 51 is provided at the other end of the adaptive screw sleeve 5, and a connecting strip 52 is symmetrically provided at the end of the buckling tube 51. The adaptive screw sleeve 5 is connected to the through hole at the bottom of the pin piece 4 through the connecting strip 52, and the half tube includes a threaded section and a buckling section; the connecting strip 52 is provided at the bottom of the buckling section, and the two half tubes are symmetrically buckled to form the adaptive screw sleeve 5.

[0051] The working principle and beneficial effects of the above technical solution: Because the height adjustment standpipe 1 and the height adjustment disc 2 are connected in a movable manner, the weight carried by the connecting crossbar 3 will all act on the outer thread through the inner thread. Taking the threaded connection as an example, the outer thread of the height adjustment standpipe 1 will bear the force from the connecting crossbar 3, and there is a risk of overflowing the buckle during long-term use. This embodiment adds an adaptive screw sleeve 5 on the basis of the invention to reduce the risk of overflowing the buckle and falling off when the height adjustment disc 2 is used for a long time or is overloaded. Taking the first embodiment of the height adjustment disc 2 as an example, conical thread grooves are set at both ends of the inner wall of the adjustment tube 7, and the diameter near the opening is larger than the inner diameter of the adjustment tube 7.

[0052] The first implementation of the adaptive screw sleeve 5 is a split and symmetric design. The adaptive screw sleeve 5 is composed of two half pipes. The two ends of the half pipes are symmetrically arranged thread segments. The inner wall of the half pipe is an inner thread that matches the outer thread. After the two half pipes are buckled together, a thread that is conical at both the top and bottom can be formed. When in use, first move the adjusting pipe 7 to a position slightly above the designated height, then buckle the two half pipes on the height-adjusting vertical pipe 1 to form the adaptive screw sleeve 5, and then move the adjusting pipe 7 downward, so that the adaptive screw sleeve 5 is connected to the thread groove of the adjusting pipe 7. The adaptive screw sleeve 5 is fixed and clamped through the adjusting pipe 7, so that the inner thread of the adaptive screw sleeve 5 is clamped with the outer thread of the height-adjusting vertical pipe 1. When the height-adjusting disc buckle 2 is used for a long time, once the outer thread of the height-adjusting vertical pipe 1 is fatigued and damaged, the conical adaptive screw sleeve 5 can form a clamping connection with the adjusting pipe 7 to prevent the height-adjusting disc buckle 2 from falling off. By setting the adaptive screw sleeve 5, the implementation mode of the outer thread of the height-adjusting vertical pipe 1 can be increased, and it can be ensured that no matter what connection method is adopted between the outer thread of the height-adjusting vertical pipe 1 and the inner thread of the adjusting pipe 7 (such as the outer thread of a horizontal clamping connection), the situation of the height-adjusting disc buckle 2 overflowing and falling off can be effectively avoided.

[0053] The second implementation of the adaptive screw sleeve 5 is a connection strengthening design. One end of the adaptive screw sleeve 5 is connected to the thread groove, and the other end is a buckling pipe 51. The buckling pipe 51 is used to fit the height-adjusting vertical pipe 1, and then is connected to the through hole at the bottom of the pin piece 4 through the connecting strip 51 at its bottom. When in use, the top of the adaptive screw sleeve 5 is still connected to the thread groove through a thread. The connecting strip 52 at the bottom can be directly connected to the through hole of the pin piece 4, or can be wound and strengthened on the buckling pipe 51 and then connected to the through hole of the pin piece 4. When the adjusting pipe 7 overflows and moves downward, it will also be clamped by the adaptive screw sleeve 5. At the same time, the connecting strip 52 is connected to the pin piece 4, so as to ensure the stability of the connection between the pin piece 4 and the height-adjusting disc buckle 2 and the connecting cross bar 3, and prevent the pin piece from being accidentally pulled out and causing the scaffold to collapse. When no accident occurs after long-term use, the adaptive screw sleeve 5 will also slowly move downward and fall off. The connecting strip 52 can prevent the adaptive screw sleeve 5 from falling off. At the same time, the excess connecting strip 52 is wound on the outer wall of the buckling pipe 51, which can also increase the overall connectivity of the adaptive screw sleeve 5 and prevent the split adaptive screw sleeve 5 from splitting and falling off without the clamping force provided by the thread groove.

[0054] The second implementation of the height-adjusting button 2 is as follows: The adjusting pipe 7 includes at least two clamping blocks. An annular groove is provided on the inner wall of the clamping block, and an inner thread adapted to the outer thread of the height-adjusting vertical pipe 1 is provided in the annular groove. A clamping strip 71 is provided on the outer wall of the clamping block, and a clamping groove is provided on the inner wall of the connecting disk 6. The clamping block is connected to the inner wall of the connecting disk 6 through the cooperation of the clamping strip 71 and the clamping groove. The connecting disk 6 includes an upper disk 61, a lower disk 62 and a connecting bolt 63; the upper disk 61 and the lower disk 62 are inserted, and the upper disk 61 and the lower disk 62 are connected by the connecting bolt 63. The upper disk 61 includes a first pressing piece 611 and a first pipe-holding part 612; the first pressing piece 611 is arranged on the outer wall of the first pipe-holding part 612;

[0055] The lower disk 62 includes a second pressing piece 621 and a second pipe-holding part 622; the second pressing piece 621 is arranged on the outer wall of the second pipe-holding part 622, and clamping grooves are provided on the inner walls of both the first pipe-holding part 612 and the second pipe-holding part 622;

[0056] The first pipe-holding part 612 and the second pipe-holding part 622 are inserted, and the first pressing piece 611 and the second pressing piece 621 overlap;

[0057] Through holes are provided on the first pipe-holding part 612 and the second pipe-holding part 622, and the connecting bolt 63 connects the first pipe-holding part 612 and the second pipe-holding part 622 through the through holes. A first slot 613 is provided on the first pressing piece 611, and the first slot 613 is adapted to the second pipe-holding part 622. A second slot 623 is provided on the second pressing piece 621, and the second slot 623 is adapted to the first pipe-holding part 612.

[0058] The working principle and beneficial effects of the above technical solution: The second embodiment of the height-adjusting button 2 is a split-type adjusting structure, which is different from the sleeve-type structure of the first implementation. The second implementation can support more types of outer threads of the height-adjusting vertical pipe 1. Taking the outer thread as an example, in the second embodiment, the major diameter of the outer thread of the height-adjusting vertical pipe 1 can be the same as the diameter of the height-adjusting vertical pipe 1, thereby reducing the processing difficulty of the height-adjusting vertical pipe 1. The thread can be directly processed on the outer wall. Since the major diameter after processing is the same as the diameter, even if the height-adjusting button 2 of the second implementation does not have an adaptor sleeve 5, when it slips off due to over-tightening, it will ultimately be clamped by the connection between the bottom of the outer thread of the height-adjusting vertical pipe 1 and the outer wall. Because the major diameter of the height-adjusting vertical pipe 1 is the same as the outer diameter, and the minor diameter is smaller than the outer diameter, once over-tightening and slipping off occur, the height-adjusting button 2 will ultimately be clamped by the height-adjusting vertical pipe 1 and stopped.

[0059] When the second implementation mode of the height-adjusting buckle 2 is in use, first, the two clamping blocks are clamped at the specified height of the height-adjusting vertical pipe 1 and buckled together to form the adjusting pipe 7. Then, the upper disc 61 and the lower disc 62 are inserted together and fixed by the connecting bolts 63 to form the connecting disc 6. The inner walls of the first pipe-clamping part 612 and the second pipe-clamping part 622 are both provided with clamping grooves connected to the clamping strips 71, so as to realize the connection between the adjusting pipe 7 and the connecting disc 6.

[0060] Also in this implementation mode, a threaded groove for connecting with the adapting sleeve 5 can be arranged on the inner wall of the adjusting pipe 7 (i.e., the inner wall of the clamping block). In this implementation mode, by dividing the height-adjusting buckle 2 into parts, the processing difficulty and processing cost are reduced. For height-adjusting vertical pipes 1 with different diameters, the traditional coping method is to separately manufacture the adapted height-adjusting buckle 2. In this embodiment, only the adjusting pipe 7 needs to be directly replaced, and there is no need to separately manufacture the connecting disc 6. Only the adjusting pipe 7 with the corresponding size needs to be selected according to the diameter of the height-adjusting vertical pipe 1, so that the height-adjusting buckle 2 can be repeatedly used while freely adjusting the height, avoiding the problem that a scaffold needs to be equipped with several different sizes of height-adjusting buckles 2.
