Abstract
The utility model discloses an underground powerhouse vault which comprises a steel bar arch rib, wherein the steel bar arch rib comprises a plurality of longitudinal steel bars arranged side by side; the plurality of longitudinal steel bars arranged side by side are connected through a plurality of horizontal steel bars which are perpendicular to the longitudinal steel bars; one steel strip which is parallel to the horizontal steel bars and is fixedly connected with the longitudinal steel bars is arranged between every two adjacent two horizontal steel bars; and one anchor rod is arranged above each steel strip, a connecting steel bar provided with a hook at the bottom is fixed at the bottom of each anchor rod, and the hook at the bottom of the connecting steel bar on each anchor rod hooks the steel strip below the anchor rod. The safety, the reliability and the stability of the steel bar arch rib are improved remarkably, the potential hazard about engineering safety and quality is eliminated, and development of the combined stress effect of the steel bar arch rib and the anchor rods is facilitated.
Description
Technical field
The utility model relates to a kind of underground power house vault.
Background technology
The general choice arrangement of underground power house is in I～II class surrounding rock stratum, but there is part Hydropower Station Underground to limit because of condition, particularly at present pumped storage power plant is often arranged in the load place close to from city greatly, therefore underground power house wall rock condition is often poor, and choice arrangement is in master's stratum at III～IV class surrounding rock, the supporting and protection structure of this class underground power house crown generally adopts the combination supporting pattern of reinforcing bar arch rib+spray steel fibrous concrete+system anchor bolt.Conventional reinforcing bar arch rib is fixing to be connected with system anchor bolt spot welding by the steel plate bar on reinforcing bar arch rib, the fusion length of steel plate bar and anchor pole welding is subject to the restriction of steel width of sheet (40mm), fusion length is narrower, therefore cause not prison welding solid, there is certain engineering safety hidden danger of quality, and be unfavorable for the performance of the coaction effect of reinforcing bar arch rib and anchor pole.
Summary of the invention
Technical problem to be solved in the utility model is, for prior art deficiency, a kind of underground power house vault is provided, make between anchor pole and steel plate bar be connected more fastening, improve safety, the reliability and stability of reinforcing bar arch rib, eliminate engineering safety hidden danger of quality.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of underground power house vault, comprise reinforcing bar arch rib, described reinforcing bar arch rib comprises the many longitudinal reinforcements that are arranged side by side, the described many longitudinal reinforcements that are arranged side by side are connected by the many transverse reinforcements vertical with described longitudinal reinforcement, between two adjacent transverse reinforcements, be provided with steel plate bar parallel with described transverse reinforcement and that be fixedly connected with described longitudinal reinforcement, each block plate bar top is provided with an anchor pole, every anchor pole bottom is all fixed with the connecting reinforcement of a root bottom part with hook, and the hook of the bottom of the connecting reinforcement on every anchor pole hooks the steel plate bar of this anchor pole below.
Described connecting reinforcement top and described anchor pole bottom lap length are 10 times of described connecting reinforcement diameter, further increase the structural strength between anchor pole and steel plate bar.
Compared with prior art, the beneficial effect that the utility model has is: the utility model easy construction, quick, owing to having increased connecting reinforcement, make between anchor pole and steel plate bar be connected more fastening, thereby safety, the reliability and stability of reinforcing bar arch rib have been significantly improved, eliminate engineering safety hidden danger of quality, and be conducive to the performance of the coaction effect of reinforcing bar arch rib and anchor pole.
Accompanying drawing explanation
Fig. 1 is the utility model one embodiment front view;
Fig. 2 is the utility model one embodiment lateral view;
Fig. 3 is the utility model one embodiment connecting reinforcement and steel plate bar connection diagram.
The specific embodiment
As shown in Figure 1-Figure 3, the utility model one embodiment comprises reinforcing bar arch rib 2, described reinforcing bar arch rib 2 comprises the many longitudinal reinforcements that are arranged side by side 3, the described many longitudinal reinforcements that are arranged side by side 3 are connected by the many transverse reinforcements 4 vertical with described longitudinal reinforcement 3, between two adjacent transverse reinforcements 4, be provided with steel plate bar 5 parallel with described transverse reinforcement 4 and that be fixedly connected with described longitudinal reinforcement 3, each block plate bar 5 top is provided with an anchor pole 1, every anchor pole 1 bottom is all fixed with the connecting reinforcement 6 of a root bottom part with hook 7, and the hook 7 of connecting reinforcement 6 bottoms on every anchor pole 1 hooks the steel plate bar 5 of this anchor pole 1 below.
As shown in Figure 1, connecting reinforcement 6 top single-sided weldings are in anchor pole 1 bottom, and in the present embodiment, connecting reinforcement 6 tops and anchor pole 1 bottom lap length are 10 times of connecting reinforcement 6 diameters.
During use, first anchor pole 1 is inserted in underground power house country rock, then with the hook 7 of connecting reinforcement 6 bottoms, hook the steel plate bar 5 of this anchor pole 1 below, until after reinforcing bar arch rib 2 contacts with country rock wall, then anchor pole 1 and connecting reinforcement 6 are welded.Excavation sideline 8 in Fig. 1 is the position that reinforcing bar arch rib 2 contacts with country rock wall, thereby reinforcing bar arch rib is fixed on country rock.
