Embodiment

Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be appreciated that herein Described embodiment is only used for describing and explaining the present invention, and is not intended to limit the present invention.

It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the utility model can To be mutually combined.

In the utility model, in the case where not making conversely explanation, the noun of locality such as " upper and lower, top, bottom " used is usually It is each component mutual alignment either on vertical, vertical or gravity direction for direction shown in the drawings Relationship description word.

The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

As shown in Figure 1, the utility model, which provides a kind of steelframe, shores component, including lower support tube 2 and upper support frame 1, on Supporting rack 1 includes shoring the supporting part of steelframe and the jacking screw 13 extended downwardly, and jacking screw 13 is downwardly into lower support tube 2 Top tube chamber in, be arranged with nut 14 on jacking screw 13, nut 14 is shored can simultaneously surround top on the top of lower support tube 2 Rotated into screw 13 to jack upper support frame 1 upwards.

During operation, the lower support tube 2 that steelframe can be shored to component is vertically placed on flat hard ground.It is rotated down and is arranged In the nut 14 on jacking screw 13, jacking screw 13 moves upwards therewith, and then jacks the steelframe 3 being erected on supporting part, Steelframe shores the elevating movement that component can be by convert rotational motion that is relatively labor-saving and being easily manipulated for 3 in the vertical direction of steelframe, Steelframe 3 is jacked to object height, only needs a people to help steelframe to shore component, other operating personnels can carry out steelframe 3 Connection and reinforcing.Compared with traditional stand, the labour of 2 to 4 operating personnels can be saved by shoring component using steelframe, and by Simple in the structure of supporting part, operating personnel's energy fast accurate, align erection by steelframe 3 securely, improves in work progress Setting support speed, ensured construction security.

Specifically, the internal diameter of the top tube chamber of lower support tube 2 is more than the outside diameter of jacking screw 13.That is, jacking silk One section of the bottom of bar 13 will be downwardly into the top tube chamber of lower support tube 2, it is necessary to meet that the inner diameter of lower support tube 2 is more than The major diameter of thread of jacking screw 13, is inserted under jacking screw 13 in the tube chamber of lower support tube 2 and can do plug rectilinear movement, lower branch Stay tube 2 ensures that steelframe is shored component and can be jacked steelframe 3 to the object height of operation.

Specifically, supporting part is U-shaped frame, and steelframe 3 is sticked in the U-lag of U-shaped frame.

Preferably, U-shaped frame includes two vertical reinforcements 11 and horizontal steel plate 12, and two vertical reinforcements 11 are welded in horizontal steel The both ends of plate 12, the top of jacking screw 13 are welded in the bottom centre of horizontal steel plate 12.Supporting part is arranged to U-shaped, can be more preferable Ground engages steelframe 3, avoids steelframe 3 from occurring situation about deflecting during jacking, operating personnel need to only help the two of steelframe 3 End, just can be not only laborsaving but also safely stablizes jacking by steelframe 3.

Preferably, the thickness of horizontal steel plate 12 is not less than 10cm not less than 10mm and width, and the diameter of vertical reinforcement 11 is not Less than 20mm.U-shaped frame includes two vertical reinforcements 11 and horizontal steel plate 12, processes and obtains in waste and old steel that can be at the construction field (site) Take, construction cost is greatly saved, such as the vertical reinforcement 11 of two a diameter of 25mm of selection and thickness are 15mm, width is The horizontal steel plate 12 of 10cm is welded into U-shaped frame, it is ensured that the U-shaped frame has enough strength and stiffness to engage and consolidates steelframe 3, Improve the security of work progress.

Preferably, the major diameter of thread d of jacking screw 13 meets：28mm≤d≤32mm.The diameter of jacking screw 13 be more than etc. In 28mm, can guarantee that steelframe shores the rigidity and intensity requirement when component meets jacking steelframe 3, avoid the occurrence of jacking screw 13 because Load-bearing capacity deficiency and abrupt bend or fracture, so as to threaten the situation of construction worker's life security.In addition, though jacking The diameter of screw 13 also meets rigidity and intensity requirement when being more than 32mm, but steelframe is shored the quality of component and can therefore be become Greatly, it is unfavorable for light assembly and disassembly and use.

Preferably, rectilinear path of the nut 14 on jacking screw 13 is no less than 100mm.Component is shored due to steelframe pushing up During rising steelframe 3, nut 14 is rotated down relative to jacking screw 13, and the rectilinear path of its in the vertical direction is equal to top The rectilinear path risen into screw, therefore rectilinear path of the nut 14 on jacking screw 13 influences the height that steelframe 3 is jacked, Its rectilinear path is no less than 100mm, then coordinates the length of lower support tube 2, it is ensured that steelframe 3 can be jacked to object height and carried out Connection is fixed.

Specifically, steelframe, which shores component, includes the lower support tube 2 of different lengths specification.Each tunnel construction site builds steel Height during frame 3 is not quite similar, and in different construction sites, steelframe need to only be shored the upper support frame 1 of component under original Extract, be inserted into meeting in another lower support tube 2 of corresponding construction height specification in support tube 2, can be switched fast for Suitable steelframe shores component and carries out constructing tunnel, has saved construction cost and construction time.

Specifically, steelframe shore component include rotation handle 15, rotation handle 15 pars intermedia be fixedly connected nut 14 with Driving nut 14 rotates.

Preferably, nut 14 is six-sided nut, and rotation handle 15 is welded on the symmetrical side of six-sided nut for level Double parallel bar.For example, the spiral that can choose two a diameter of 20mm chooses six-sided nut conduct as rotation handle 15 Two rotation 15 levels of handle are welded on formation double parallel bar on the symmetrical side of nut 14, add rotating mechanism by nut 14 The arm of force, enable operating personnel preferably handle, and more effortless by 14 turn of nut, improve steelframe and shore component Operability.

The preferred embodiment of the utility model, still, the utility model and unlimited are described in detail above in association with attached drawing Detail in the above embodiment, can be to the skill of the utility model in the range of the technology design of the utility model Art scheme carries out a variety of simple variants, these simple variants belong to the scope of protection of the utility model.

It is further to note that each particular technique feature described in above-mentioned embodiment, in not lance In the case of shield, it can be combined by any suitable means, in order to avoid unnecessary repetition, the utility model is to each The possible combination of kind no longer separately illustrates.

In addition, it can also be combined between a variety of embodiments of the utility model, as long as it is not disobeyed The thought of the utility model is carried on the back, it should equally be considered as content disclosed in the utility model.
