Description
Technical field
The present invention relates to a kind of in steel pipe concrete bracket a kind of sleeve structure for joint steel pipe concrete support nation section steel pipe and end arch section steel pipe, particularly relate to one and allow pressure type base angle sleeve pipe.
Background technology
Base angle sleeve pipe is a kind of sleeve structure for joint steel pipe concrete support nation section steel pipe and end arch section steel pipe in steel pipe concrete bracket.Due to the requirement of coal mine roadway design of section, in steel pipe concrete bracket structured design process, have two nation's section steel pipes unavoidably encircle section steel pipe situation crossing at an angle the end of with, in this case, two nation's sections and the end, encircle between section steel pipe base angle sleeve pipe just must be used to be connected, base angle sleeve pipe should have stronger compliance to the duty of steel pipe concrete bracket, could ensure that support can not produce structural instability because base angle sleeve pipe occurs to destroy.
In prior art, steel pipe concrete bracket is generally applied to the Deep Soft Rock tunnel of complex geologic conditions, and under this geological conditions, steel pipe concrete bracket load is large, and support allows certain distortion occurs.Existing base angle sleeve pipe is generally be welded according to certain angle docking by two of two fixed-calibers sections of steel pipes, this base angle sleeve pipe can not adapt to the rotary deformation that section is encircleed at support two nation and the end, the intensity of weld is also not enough to the moment of flexure produced when resisting deformation of timbering, easily tear at base angle sleeve pipe weld and sleeve opening place, therefore support produces structural instability.
Summary of the invention
The object of this invention is to provide a kind of strong adaptability, structure and allow pressure type base angle sleeve pipe reliably.
The object of the invention is to be achieved through the following technical solutions:
The pressure type base angle sleeve pipe that allows of the present invention, is characterized in that, comprises the bell mouth shape main body steel pipe of two sections of obliques, is provided with built-in boss at the inwall of two sections of bell mouth shape main body steel pipe intersections.
As seen from the above technical solution provided by the invention, what the embodiment of the present invention provided allow pressure type base angle sleeve pipe, is characterized in that, comprise the bell mouth shape main body steel pipe of two sections of obliques, be provided with built-in boss at the inwall of two sections of bell mouth shape main body steel pipe intersections.To the large deformation produced in steel pipe concrete bracket work, high strength, there is better compliance, can effectively prevent steel pipe concrete bracket from destroying at sleeve pipe place, base angle.

Detailed description of the invention
To be described in further detail the embodiment of the present invention below.
The pressure type base angle sleeve pipe that allows of the present invention, its preferably detailed description of the invention be:
Comprise the bell mouth shape main body steel pipe of two sections of obliques, be provided with built-in boss at the inwall of two sections of bell mouth shape main body steel pipe intersections.
Flank and the back of the outer wall two sections of bell mouth shape main body steel pipe intersections longitudinally arrange stiffener respectively.
The bore of described bell mouth shape main body steel pipe increases outward gradually to intersection.
Longitudinal width of described built-in boss reduces to flank gradually from back.
The pressure type base angle sleeve pipe that allows of the present invention, can adapt to the duty of steel pipe concrete bracket in Deep Soft Rock roadway support, can meet following requirement:
(1) encircle the rotary deformation of section Xia Liang nation section and the end in working order to adapt to steel pipe concrete bracket; (2) position of end arch section and two nation's sections is effectively limited; (3) base angle sleeve pipe has higher structural strength.
Specific embodiment:
Base angle sleeve pipe adopts cast steel casting or steel-pipe welding to form, and according to different support outer diameter of steel pipes, determines the caliber size of base angle sleeve pipe and the wall thickness of each component.
As shown in Figure 1, Figure 2, Figure 3 shows, mainly comprise the parts such as bell mouth shape main body steel pipe 1, built-in boss 2, stiffener 3, each several part specifically describes as follows:
(1) main body steel pipe bell mouth shape design:
The design of main body steel pipe bell mouth shape be exactly casing main body steel pipe be horn-like, and more bore is larger the closer to sleeve opening edge for steel pipe, has angle to be the revolution surplus of α after stand steel pipe loading sleeve pipe.Base angle casing main body steel pipe is bell mouth shape, and after stand steel pipe loads base angle sleeve pipe, nation's section and end arch section can be allowed to produce angle when rack bearing is stressed be the revolution of α, effectively can adapt to the large deformation feature in Deep Soft Rock roadway support.
(2) built-in boss design:
Built-in boss arranges built-in boss in sleeve pipe upper and lower two parts main body steel pipe intersection exactly, and built-in boss smoothly can transmit nation's section and the end and encircle active force between section, and can fix nation's section and fragment position is encircleed at the end, can the position of effective location nation section and end arch section.
(3) design strengthened by sleeve pipe:
Sleeve pipe is strengthened design and is arranged stiffener respectively at sleeve pipe flank and back exactly, thickeies process to sleeve pipe mouth of pipe edge steel pipe.Stiffener can improve base angle casing strength, and sleeve opening edge strengthens, and can effectively prevent sleeve opening from tearing.
The operating principle of specific embodiment is:
As shown in Figure 4, when steel pipe concrete bracket be subject to the effect of outer peripheral rock pressure power deform time, support nation section 4 and the end encircle section 6 all can occur in move, because the effect of contraction of section 6 termination is encircleed at base angle sleeve pipe 5 pairs of nation's sections 4 and the end, support nation section 4 and the end, encircle section 6, around base angle sleeve pipe 5, rotary deformation occur.Base angle sleeve pipe 5 adopts bell mouth shape sleeve pipe to can be nation's section 4 and the end to encircle section 6 and provide angle to be the revolution surplus of α, and to encircle the power that section acts on the sleeve pipe of base angle less support nation section and the end in the process.When support be subject to larger power continue to deform time, support nation section 4 and the end, encircle section 6 and namely contact with base angle internal surface of sleeve pipe, the power that support acts on base angle sleeve pipe 5 progressively increases, the effect of being under pressure of base angle sleeve pipe 5 flank, back under tension effect, then base angle sleeve pipe flank stiffener and back stiffener play a role, and add the intensity of base angle sleeve pipe.When sleeve pipe mouth of pipe edge, base angle is subject to support nation section and section active force is encircleed at the end, easily there is tear failure at mouth of pipe place, so thicken process to sleeve pipe mouth of pipe edge.
As shown in Figure 5, be footing sleeve pipe stereogram.
Application the present invention is when steel pipe concrete bracket needs base angle sleeve pipe to connect, base angle of the present invention sleeve pipe has better compliance to the large deformation produced in steel pipe concrete bracket work, high strength, can effectively prevent steel pipe concrete bracket from destroying at sleeve pipe place, base angle.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
