Description
Technical Field
The utility model relates to a mountain region plank road installation field, concretely relates to column base mounting structure of steel construction plank road.
Background
In mountainous or hilly terrain, it is often necessary to build footpaths or trestles on the mountainous terrain for ease of passage. At present, when a plank road or a footpath is constructed, a concrete structure plank road, a steel structure plank road and a wood structure plank road are mainly used. Concrete structure plank road structural strength is high, but the transport material of not being convenient for, and there is the life weak point in the timber structure plank road, the problem that maintenance cost is high, and based on this, the steel construction plank road is more suitable for in mountain region or hilly land. At present, the steel structure plank road mainly includes the landing stage and follows the many pairs of stands of landing stage length direction interval setting, every pair of stand sets up along landing stage width direction to fix on a cushion cap base. A plurality of embedded bolts are embedded in the bearing platform base, and the stand column is fixed on the bearing platform base through a plurality of bolts after the embedded bolts penetrate through a stand column bottom plate at the lower end of the stand column. The mounting structure of above-mentioned bolt is firm inadequately, and simultaneously, current stand except bearing vertical pressure, in concrete use, still need bear the horizontal thrust that comes from the instrument of communication on the landing stage, can have the fracture phenomenon after long-time the use.
Disclosure of Invention
To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a structure firm, simple to operate's column foot mounting structure of steel construction plank road.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a column base mounting structure of a steel structure plank road comprises a bearing platform base and two stand columns fixed on the bearing platform base at intervals, and is characterized in that a plurality of upper positioning steel bars and lower positioning steel bars are fixed on bearing platform steel bars of the bearing platform base corresponding to mounting positions of the two stand columns, and a plurality of embedded bolts with upper ends extending out of the bearing platform base and lower ends fixed with the lower positioning steel bars are fixed on the upper positioning steel bars; the bottom of each upright post is provided with a bottom plate which is horizontally arranged, the upper end of each embedded bolt penetrates through the bottom plate, and the upper side and the lower side of the bottom plate of each upright post and each embedded bolt are respectively provided with a fastening nut and an adjusting nut. Like this, the last spacer bar that sets up is corresponding with stand mounted position with lower spacer bar mounted position, and during the installation, the mounted position that sets for according to buried bolt in advance comes fixed mounting spacer bar to can play indicative effect to buried bolt in advance mounted position, the installation is more convenient and firm with fixed. Every embedded bolt all has two fixed points with the spacer bar, and colludes on spacer bar down after the lower extreme bends, when concrete placement, also is difficult for shifting. The bottom plate arranged on the stand column can increase the installation area of the stand column and the bearing platform base, and the column base reinforcing plate can effectively improve the strength of the lower end of the stand column, so that better support can be realized when the stand column is subjected to lateral or horizontal thrust, and the phenomenon of fracture cannot occur.
Furthermore, a cast-in-place pile which goes deep into the ground is further arranged in the middle of the bearing platform base and below the bearing platform base, and a reinforcement cage in the cast-in-place pile extends out of the cast-in-place pile and is welded and fixed with a bearing platform reinforcement in the bearing platform base. Therefore, the filling pile arranged below the bearing platform base extends into the ground, so that the bearing platform base has a better connecting foundation and is fixed with the stratum, has better stability and can bear larger external force. Steel reinforcement cage and cushion cap reinforcing bar fixed connection in the bored concrete pile can effectively be connected into a whole with cushion cap base and bored concrete pile, effectively transmits the external force that the plank road received the underground through stand and cushion cap base.

Therefore, the arranged I-steel is embedded in the bearing platform base, a certain shearing effect is achieved, and the connection strength of the stand column and the bearing platform base can be effectively improved.
Furthermore, a concrete reinforcing column which wraps the embedded bolt and the lower end of the stand column is poured on the bearing platform base and at the corresponding position of each stand column. Like this, concrete reinforcement post can effectively form the protection to pre-buried bolt, prevents long-time back of using, and the bolt is rusted, is corroded.
Further, all be equipped with eight inboard column base gusset plates with stand fixed connection, lower extreme and bottom plate fixed connection on every stand, every column base gusset plate all is located the stand corner, and the setting of perpendicular to stand, all is equipped with a mounting hole that is used for wearing to establish buried bolt in advance on the bottom plate between per two adjacent column base gusset plates. Like this, column base gusset plate circumference is equidistant to be set up, separates the stand outside for eight bolt installation spaces, and the bolt also is equidistant around stand circumference for the stand atress is even.
Furthermore, a pressing plate which is horizontally arranged is arranged on each embedded bolt and on the upper side and the lower side of the bottom plate, and the pressing plate is positioned between the fastening nut and the bottom plate and between the adjusting nut and the bottom plate. Therefore, the pressing plate can avoid the direct contact between the nut and the bottom plate, and the nut is effectively protected.
Furthermore, the upper positioning steel bars and the lower positioning steel bars are arranged in a one-to-one correspondence mode, and the bottoms of the embedded bolts are bent and then hooked on the lower positioning steel bars. Like this, after the positioning bar one-to-one, can ensure that the fixed back of buried bolt is vertical setting, fix a position buried bolt in advance, and buried bolt bottom colludes behind on positioning bar down, can further improve buried bolt's pulling force in advance.
