Work station number for an overhauling test of the parts of the water supply and drainage system is small and the volumes of the parts are relatively large, so that an electric hoisting trolley is used for finishing the transportation of each part, ascending and descending a worktable and the like; corresponding equipment including the worktable, a test-bed, a control platform, a tool case and the like is arranged on each overhauling and assembling test region, thereby realizing the overhauling work of storing, decomposing, overhauling, assembling, testing and the like of the water supply and drainage system.

The invention discloses a fatigue testing machine capable of applying complex coupling force, which comprises a gantry frame, and a specimen fixing frame is arranged between two vertical arms of the gantry frame; The horizontal slideway mechanism for the distance between the gantry and the specimen fixing frame, the vertical arm of the gantry is equipped with a vertical lifting mechanism, the vertical lifting mechanism is equipped with a fatigue test power mechanism, and the fatigue test power mechanism is equipped with a distance adjustment mechanism ; It also includes the control system for controlling the power mechanism of the fatigue test and the testing machine. The testing machine is small in size and easy to move, and the testing machine can apply the coupling effect of complex loads of different proportions, which can better simulate the complex force in the real bridge Conditions provide an experimental basis for the study of fatigue performance.

The invention discloses a method using aluminum formwork to pour a floor roof. The method has the advantages that by mounting a matched aluminum combined body for manufacturing a conveying hole, the conveying hole can be formed after top floor pouring to allow small-sized building equipment such as aluminum formwork to be conveniently conveyed from a lower layer to an adjacent upper layer, the useof large machinery is avoided, repeated carrying by workers is avoided, worker labor intensity is lowered, and construction efficiency is increased effectively.

A safety device for lithium-ion batteries, including a cabinet body; at least one row of battery compartments are arranged in the cabinet body, the upper end of the battery compartment is open, and the battery compartment is composed of an insulating fireproof layer on the inner layer and a stainless steel layer on the outer layer ; The battery compartments are connected in series through shafts to form a battery compartment row. The two ends of the battery compartment row are respectively provided with rotating shafts, and both ends of the rotating shaft pass through the side wall of the cabinet body; Battery positioning mechanism. The present invention uses a battery compartment with a two-layer structure so that the battery has a good insulation effect from the outside world, and avoids short-circuiting of the battery due to careless operation by personnel or other accidents. The battery compartment with a two-layer structure also has a high explosion-proof capability; by using the structure of the battery compartment's rotating shaft, the battery can be turned over at multiple angles during the static stage (to improve the effect of electrolyte infiltration), avoiding the need for manual handling of the batteries one by one. Flip, the workshop production efficiency is greatly improved.

The invention discloses a formwork assembly structure with an aluminum mold assembly, which comprises a continuously tiled top formwork, the lower part of the top formwork is supported by evenly spaced top support devices, and an aluminum mold assembly is also installed on the top formwork. After the top plate is poured, a material transfer hole can be formed on the top plate of the dismantled aluminum mold assembly; the aluminum mold assembly is welded by aluminum formwork, and the whole is an inverted hollow quadrangular truss structure. By installing the aluminum formwork assembly for making material transfer holes on the top formwork, the material transfer holes are formed after the top floor slab is poured, so as to facilitate the transfer of aluminum formwork and small-volume construction equipment from the lower floor to the adjacent upper floor, avoiding the The intervention of large-scale machinery also avoids the repeated handling of workers, reduces the labor intensity of workers, and effectively improves the construction efficiency.

The invention discloses a BIM building security device which comprises apre-buried frame, a fixing structure, a rotating shaft, a first gear, a supporting rod, a speed reducing structure, a speed reducing belt and a guardrail. The device has the beneficial effects that through the arranged pre-buried frame, the guardrail used for sealing the entrance and exit can be stored underground, meanwhile,the speed reducing belt is arranged at the top end of the pre-buried frame, and therefore the speed reducing belt and the guardrail can be switched according to the requirements of different situations, and when the guardrail is pulled out, the first gear can be rotated to enable the supporting rod fixedly connected with the side face of the first gear to rotate by 90 degrees, so that the bottom of the guardrail is supported through the supporting rod, at the moment, due to the supporting effect of the supporting rod on the guardrail, the guardrail can be kept in a fixed state outside the ground surface, and the function of blocking an entrance and exit is achieved; and when the guardrail is stored, the guardrail can be placed in the pre-buried frame again only by rotating the supporting rod again to abut against the inner side wall of the pre-buried frame, and use is convenient.
