Description
Technical field
This utility model relates to Deep Foundation Pit Supporting Project field, is specifically related to a kind of bracing members segmented head.
Background technology
At present, in municipal administration Construction of Deep Excavation Engineering, for ensureing deep basal pit stability, bracing members is in actual applications widely. Bracing members segmented head in traditional design is shown in Figure 1, and it includes two movable ends 1 ' and a fixing end 2 ' and is welded on the transition segment 3 ' on fixing end 2 ', and this segmented head structure is complicated, from great, should not process and assembling and disassembling inconvenience.
The rear end of movable end can be inserted into the inner chamber of fixing end, and can interior external extension. In use, movable end is made to move after first passing through jack pressurization, when putting into gag in space between movable end force bearing plate and fixing bottom bearing plate after moving into place, to keep the position of movable end, finally withdraw jack, but the face that its movable end force bearing plate of current segmented head contacts with gag is plane, when pressure is shored in adjustment, need the quantity increasing or reducing gag to realize the adjustment of displacement, operate cumbersome.
Utility model content
For the defect existed in prior art, the purpose of this utility model is in that to provide the segmented head of a kind of only one of which movable end, simple in construction and need not increase or reduce the bracing members segmented head of gag quantity when adjusting axle power.
For reaching object above, this utility model adopts the technical scheme that: a kind of bracing members segmented head, including,
One fixing end, it includes the first force bearing plate, and is positioned at the receiving space of described first force bearing plate both sides;
Movable end at least partially embedded described receiving space, described movable end can in external extension, it includes end plate, and is fixedly arranged on described end plate and the second force bearing plate arranged that aligns with described first force bearing plate, and described second force bearing plate is lozenges away from one end of described end plate; And
Gag position between described first force bearing plate and the second force bearing plate, is provided with wedge shape gag in described gag position.
On the basis of technique scheme, described end plate being fixedly provided with two guide plates, described second force bearing plate is between two described guide plates, and described guide plate can reciprocate in described receiving space.
On the basis of technique scheme, described gag position is surrounded by described first force bearing plate and the second force bearing plate and guide plate.
On the basis of technique scheme, described end plate is additionally provided with floor of putting more energy into.
Compared with prior art, the utility model has the advantage of:
(1) the bracing members segmented head in this utility model, only includes a movable end, compares traditional segmented head being provided with two movable ends, and its simple in construction, deadweight reduction have been saved cost, and be easily installed and process.
(2) the bracing members segmented head in this utility model, the second force bearing plate on its movable end is lozenges away from one end of end plate, the lozenges of this lozenges and wedge shape gag is fitted, therefore in use have only to one piece of wedge shape gag, when pressure is shored in needs adjustment, the position having only to adjustment wedge shape gag can realize the adjustment of movable end displacement, simple to operation.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Referring to shown in Fig. 2 and Fig. 3, this utility model provides a kind of bracing members segmented head, including fixing end 1, movable end 2 and gag position 3.
Shown in Fig. 5, wherein fixing end 1 includes the first force bearing plate 11, and is positioned at the receiving space of the first force bearing plate 11 both sides.
Referring also to shown in Fig. 4 and Fig. 6, movable end 2 includes end plate 21, and end plate 21 is installed with two guide plates 23 and the second force bearing plate 22 arranged that aligns with the first force bearing plate 11. Second force bearing plate 22 is between two guide plates 23, and it is lozenges away from one end of end plate 21. In order to increase the load ability of movable end 2, it is additionally provided with, at end plate 21, floor 24 of putting more energy into.
Shown in Fig. 6, gag position 3 is surrounded by the first force bearing plate 11 and the second force bearing plate 22 and guide plate 23, is provided with wedge shape gag 31 in it, and lozenges and second force bearing plate 22 of wedge shape gag 31 are fitted, and another horizontal plane and the first force bearing plate 11 are fitted.
Bracing members segmented head in this utility model, only includes a movable end 2, compares traditional segmented head being provided with two movable ends, and its simple in construction, deadweight reduction have been saved cost, and be easily installed and process. In addition the bracing members segmented head in this utility model, the second force bearing plate 22 on its movable end 2 is lozenges away from one end of end plate 21, the lozenges of this lozenges and wedge shape gag 31 is fitted, therefore in use have only to one piece of wedge shape gag 31, when pressure is shored in needs adjustment, jack is utilized to be strutted by movable end 2, then the position having only to adjust wedge shape gag 31 can make in movable end 2 external extension to carry out the adjustment of pressure, after having adjusted, remove jack, the latching characteristics utilizing lozenges forms self-locking, whole simple to operation.Additionally, the angle of inclination of the lozenges of wedge shape gag 31 and the second force bearing plate 22 can need appropriate design according to movable end 2 stroke.
This utility model is not only limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but in its shape or structure, do any change; every have same or like with this utility model like technical scheme, all within its protection domain.
