Detailed description of the invention
The support of mine of the present invention concrete support engineering and an embodiment of erection method thereof are described below with reference to the accompanying drawings.Those of ordinary skill in the art can recognize, when without departing from the spirit and scope of the present invention, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.In addition, in this manual, identical Reference numeral represents same or analogous part.
The support of mine of the present invention concrete support engineering will be described for mine down-hole ingate below.Ingate is the connection place of vertical shaft and roadway, and likeness in form head of the horse is oblique top formula.Fig. 1 shows the cross section of the support for ingate support engineering described in one embodiment of the present of invention, and Fig. 2 shows the longitudinal section of the support for ingate support engineering described in one embodiment of the present of invention.
As depicted in figs. 1 and 2, the support 100 for ingate 1 support engineering described in one embodiment of the present of invention comprises: post leg 10a and 10b, multiple horizontal support 20, multiple vertical supports 30, two longeron 40a and 40b and multiple bow member 50 that two row are upright.
One colonnade leg 10a and another colonnade leg 10b one_to_one corresponding in order, side and the top of every bar post leg 10a or 10b are equipped with butt joint.Fig. 3 show described in one embodiment of the present of invention for post leg 10a(or 10b in the support 100 of ingate support engineering) schematic diagram.As shown in Fig. 1 to Fig. 3, every bar post leg in one colonnade leg 10a and the side of the corresponding post leg in another colonnade leg 10b are provided with multipair butt joint 11 relative to one another, the side of two post legs adjacent in every colonnade leg 10a or 10b arranges a pair butt joint 12 relative to one another, the top (that is, the upper bottom surface of post leg) of each post leg 10a or 10b is provided with butt joint 13.
Butt joint 11 comprises fixing (such as, by welding) steel plate on post leg side, and this steel plate is formed multiple hole (such as symmetrically arranged 2 or 4 holes).Butt joint 12 is made up of fixing (such as by welding) round steel pipe on post leg side.In another embodiment, butt joint 12 also can form the butt joint similar with butt joint 11.Butt joint 11 and butt joint 12 are all at least a pair, and wherein, butt joint 11 is preferably multipair, and butt joint 12 is preferably a pair.
In the present embodiment, longitudinal section due to ingate 1 is oblique top formula, therefore, as shown in Figure 2, the height of the post leg in each post leg row 10a or 10b in two post leg row 10a and 10b reduces successively, make two longeron 40a with 40b carrying out docking with this two colonnades leg 10a with 10b respectively with identical slope inclination, in addition, as shown in Figure 1, two skewback portion 51a and 51b of each bow member 50 docked with two longeron 40a and 40b are located in the same horizontal plane (in fig. 2 not shown bow member 50).In this case, as shown in Figure 3, the upper bottom surface of post leg is tilt relative to its bottom surface, and butt joint 13 comprises the steel plate be fixed on post leg upper bottom surface (that is, top), this steel plate is formed with multiple hole (such as, symmetrically arranged 4 holes), therefore, the butt joint 13(be fixed on this upper bottom surface is, be formed with the steel plate in multiple hole) be also tilt, to dock with the longeron tilted.
In another embodiment, for general chamber and gallery, its longitudinal section is flat roof type, therefore, the height of each post leg in two colonnade leg 10a with 10b can be identical, and the upper bottom surface of post leg is parallel relative to its bottom surface, therefore, the butt joint 13 be fixed on this upper bottom surface is just parallel to the bottom surface of post leg, so that the longeron of level docks.
Post leg 10a or 10b is made up of one or more section bars in round steel, round steel pipe, square steel, square steel pipe and i iron.In addition, the form that the one or more post legs in two colonnade leg 10a and 10b can be docked by multistage is formed (not shown in Fig. 1 to Fig. 3).The advantage adopting the mode of multistage docking to form post leg is easy standardization, and forms the post leg of various height by the mode of combination, in the supporting for the ingate of various sizes and shape, chamber, gallery.
