Description
Technical Field
The utility model relates to a mining supporting device, especially a concatenation formula T shaped steel area roof beam is strutted to coal road group portion.
Background
The T-shaped steel strip beam is a roadway support material formed by cold pressing of a high-strength alloy plate, and is combined with an anchor rod to form a joint body for common support. The anchor rod has strong integrity and high strength, can enlarge the anchor rod supporting action range, realizes the dispersion of the prestress and the working resistance of the anchor rod, and ensures that the load of a supporting area is uniform.
A front step construction method is often adopted for facilitating roof support in underground coal roadway construction, and the installation method of the original upper T-shaped steel belt beam comprises the following steps: the installation of the upper T-shaped steel belt beam of the roadway side is completed, the anchor rod cap and the tray at the lower end of the upper T-shaped steel belt beam are removed after the construction of the lower roadway is completed, the lower T-shaped steel belt beam is lapped, the side coal damage is easily aggravated due to repeated lapping, the installation process is complex in construction, and therefore a T-shaped steel belt beam lapping structure needs to be innovated.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a concatenation formula T shaped steel area roof beam is strutted to coal road group portion, need not to relapse the overlap joint, reduces the condition that group portion coal body aggravation destroyed.
The technical scheme of the utility model: the utility model provides a concatenation formula T shaped steel belt roof beam is strutted to coal road group portion, includes upper segment T shaped steel belt roof beam and hypomere T shaped steel belt roof beam, its characterized in that: the lap joint of the upper section T-shaped steel belt beam and the lower section T-shaped steel belt beam is movably connected; the anchor rod supporting hole groups are uniformly arranged on the two steel belt beams and used for placing anchor rods, each anchor rod supporting hole group is provided with two holes, one hole is an anchor rod supporting hole, and the other hole is an anchor rod supporting spare hole used for additionally drilling the anchor rods.
The lap joint of the upper section T-shaped steel belt beam and the lower section T-shaped steel belt beam is movably connected, namely, corresponding fixing holes are respectively formed in the joint of the two sections of steel belt beams, and a high-strength bolt is matched with a matched gasket and penetrates into the fixing holes to be fastened and connected through a nut.
The distance between the anchor rod supporting hole and the anchor rod supporting standby hole is 100 mm.
The utility model discloses a concatenation formula T shaped steel band roof beam need not to relapse the overlap joint and causes group's coal body to destroy, only needs to use two steel band roof beams of high-strength bolted connection, forms the overlap joint section that overlap joint intensity is higher than main material intensity, and processing is simple, construction convenience, and the whole supporting effect of tunnel group portion is good.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings:
as shown in FIG. 3, the structure of the upper T-shaped steel belt beam 1 is that the upper T-shaped steel belt beam is 2100mm long, two fixing holes 7 with 20mm diameter are opened at the end, the center distance between the two holes is 70mm, and one hole is 30mm away from the end of the upper T-shaped steel belt beam. Anchor rod support hole 8 has evenly arranged threely according to steel band roof beam length on upper segment T type steel band roof beam 1 to increase an anchor rod support spare hole 9 in each 100mm department apart from former anchor rod support hole, prevent that the anchor rod 3 is unqualified in construction, can mend and beat anchor rod 3.
As shown in fig. 4, in the structure diagram of the lower T-shaped steel strip beam 2, the length of the lower T-shaped steel strip beam 2 is 1730mm, two fixing holes 7 with the diameter of 20mm are formed at the end, the center distance between the two holes is 70mm, and one hole is 30mm away from the end of the lower T-shaped steel strip beam 2. Two anchor rod supporting holes 8 are uniformly arranged according to the length of the lower section T-shaped steel belt beam 2, and a standby anchor rod supporting hole 9 which is used for placing an anchor rod unqualified in construction and can be used for repairing the anchor rod is additionally arranged at the position 100mm away from each anchor rod supporting hole.
As shown in fig. 1, two high-strength bolts 4 with a diameter of 16mm are used to match with matching gaskets 5 to pass through two fixing holes 7 formed in an upper section of the T-shaped steel strip beam 1 and a lower section of the T-shaped steel strip beam 2, and are fastened through nuts 6, and the lap joint structural strength is higher than that of a main material.
The specific construction method comprises the following steps: as shown in fig. 1 and 2, after the upper section T-shaped steel strip beam 1 is installed, when the lower roadway is constructed, two high-strength bolts 4 with the diameter of 16mm are directly used to match with the matching gaskets 5, nuts 6 are connected with the two T-shaped steel strip beams, the lap joint strength is higher than the main material strength, and the overall supporting effect is achieved.
The foregoing is illustrative of the present invention and its embodiments, and the description is not intended to be limiting. The embodiment shown in the drawings is only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is informed by the teaching of the present invention, without departing from the spirit of the present invention, the present invention shall not be limited to the embodiments and structural modes similar to the above technical solutions.
