Abstract
The utility model provides a special steel support with the length capable of being adjusted freely, and relates to the technical field of design of tools for building. The special steel support comprises a telescopic rod, an outer support pipe and a rotary block valve; a lower jacking plate is arranged at the lower end of the outer support pipe, an upper jacking plate is arranged at the upper end of the telescopic rod, and a reset adjustment spring is arranged inside the outer support pipe and between the lower end of the telescopic rod and the lower jacking plate; handles are arranged on the outer side of the rotary block valve, and sliding wheels are arranged at the bottom of the rotary block valve; two opposite end faces of the telescopic rod are planes, and another two opposite end faces of the telescopic rod are cambered surfaces protruding outwards; a plurality of grooves are symmetrically and evenly distributed in each cambered surface of the telescopic rod; a pair of protrusions are symmetrically arranged on the inner circumferential wall of the rotary block valve, and a through hole with the same section shape as the body of the telescopic rod is formed inside the rotary block valve. According to the special steel support, the rotary block valve is rotated by 90 degrees, the protrusions are tightly and fixedly meshed with one pair of grooves in the telescopic rod, and therefore a supporting process is finished; labor is saved, operation is convenient, no other auxiliary means are needed in the whole process, and operation is convenient and rapid.
Description
Technical field
The utility model relates to the design field of instrument for building, and particularly a kind of profile iron that can freely adjust length supports.
Background technology
Development along with urban construction, on the ground or underground construction environment also complicated and changeable, the quality of construction, safety are also had higher requirement, existing support system operational sequence is complicated, time-consuming, effort, peace is torn inconvenience open, and the intensity of support system, rigidity, stability, safety are inadequate, cannot extensively apply flexibly the demand in the support systems such as in building field different landforms, geological conditions underbeam, plate, column template, deep foundation pit support.
Utility model content
The utility model object is for above problem, provide a kind of easy to operate, be widely used, the safe profile iron that can freely adjust length supports.
The utility model comprises expansion link, supports outer tube, revotating card valve, and described revotating card valve is arranged on the upper end of supporting outer tube, and described expansion link can be set in support outer tube by up-and-down motion type through revotating card valve; Lower end at described support outer tube arranges lower roof plate, in the upper end of described expansion link, upper plate is set, and in described support outer tube, between the lower end of expansion link and lower roof plate, arranging resets adjusts spring; Outside at described revotating card valve is provided with handle, in the bottom of described revotating card valve, pulley is set; Wherein two relative end faces of described expansion link are plane, another two cambered surfaces that relative end face is outwardly convex; Respectively symmetrical uniform several grooves in two cambered surfaces of described expansion link, described each groove is from top to bottom horizontally disposed with along the expansion link body of rod; On the internal perisporium of described revotating card valve, be symmetrical arranged a pair of projection matching with expansion link two ends groove, in described revotating card valve, be provided with the through hole identical with expansion link body of rod cross sectional shape that the internal perisporium by revotating card valve forms jointly with a pair of projection.
The utility model in use, lower roof plate is entirely placed in to fulcrum one end, revotating card valve regulation and Yi Zhi position, expansion link cross section, the adjustment spring that resets can help expansion link to adjust to applicable length, rotary handle is by revotating card valve half-twist, make the wherein a pair of groove that arranges on the projection of establishing in revotating card valve and expansion link tightly interlock fix, upper plate is close to other end fulcrum, completes whole support process.During dismounting, only need operating grip, by revotating card valve half-twist round about, after reset, abnormity expansion link can freely be retracted, and the pulley that revotating card valve is divided into, helps through rotation, laborsaving convenient again, whole process is without by other aid, simple operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
The specific embodiment
As shown in Figure 1, 2, the utility model comprises expansion link 1, supports outer tube 2, revotating card valve 3, and described revotating card valve 3 is arranged on the upper end of supporting outer tube 2, and described expansion link 1 can be set in support outer tube 2 by up-and-down motion type through revotating card valve 3; In the lower end of supporting outer tube 2, lower roof plate 4 is set, in the upper end of expansion link 1, upper plate 5 is set, in supporting outer tube 2, reset adjustment spring 6 is set between the lower end of expansion link 1 and lower roof plate 4; In the outside of revotating card valve 3, be provided with handle 7, in the bottom of revotating card valve 3, pulley 8 be set; Wherein two relative end faces of expansion link 1 are plane 1-1, another two cambered surface 1-2 that relative end face is outwardly convex; Respectively symmetrical uniform several grooves 9 on two cambered surface 1-2 of expansion link 1, each groove 9 is from top to bottom horizontally disposed with along expansion link 1 body of rod; On the internal perisporium of revotating card valve 3, be symmetrical arranged a pair of projection 10 matching with expansion link 1 two ends groove 9, in revotating card valve 3, be provided with internal perisporium and a pair of protruding 10 through holes 11 identical with expansion link 1 body of rod cross sectional shape that jointly form by revotating card valve 3.
