A slope concrete pouring self-elevating formwork comprises side molds, a top mold, rails, walking mechanisms and vibrating mechanisms, the side molds are fixed to the two sides of a concrete pouring slope, the rails are installed on the two sides of the side molds, the top mold is arranged on the tops of the side molds, the walking mechanisms are connected with the top mold and matched with the rails, and the vibrating mechanisms are fixed to the top mold. The walking mechanisms drive the top mold to ascend and descend along the side molds for leveling, the vibrating mechanisms simultaneouslyvibrate and conduct compacting, and the heights of the rails can be adjusted. According to the formwork, the problems that the labor intensity is large, the density is uneven and unevenness is causedduring existing slope concrete pouring are solved. The formwork has the advantages that the structure is simple, multi-layer pouring operation can be carried out by adjusting the heights of the rails,the labor intensity is low, the formwork is compact and uniform, the levelness is convenient to control, and the formwork is simple and convenient to operate.

The invention discloses an electronic incense furnace which can enable temperatures of a furnace body and an illumination module to be lower. The electronic incense furnace comprises a furnace body, a heating module and an illuminating module, wherein a light-transmitting part surrounding the illuminating module is arranged on the furnace body, and the heating module comprises a heat-conducting disk, a heating sheet, a heat-insulating layer and a fixed disk which are sequentially connected from top to bottom; the illuminating module is positioned below the fixed disk and also comprises a heat-insulating plate which is positioned between the fixed disk and the illuminating module, a first ventilating structure which enables air in the illuminating module to flow towards the fixed disk is arranged on the heat-insulating plate, a gap enabling air from the first ventilating structure to flow out exists between the heating module and the furnace body; a heat-insulating column is arranged at the joint of the fixed disk and the furnace body and provided with a through hole enabling a connecting member of the heating module, which is arranged on the furnace, to penetrate through; and the furnace body is provided with a second ventilating structure enabling air to flow into the illuminating module.

The invention discloses a precise locating mounting connecting structure of assembled wall boards and a beam body, and belongs to the field of assembled building connecting structures. A pre-buried C-type steel sliding groove component is arranged on a side bearing table of a reinforced concrete precast beam, and two C-type steel sliding grooves of the pre-buried C-type steel sliding groove component are correspondingly exposed on the upper surface and the lower surface of the side bearing table; adjustable locating connecting pieces are groove type steel pieces, and transverse long-strip oval holes perpendicular to the groove edges are formed in the groove bottom faces of the adjustable locating connecting pieces; the two adjustable locating connecting pieces are connected and located with the C-type steel sliding grooves of the pre-buried C-type steel sliding groove component of the reinforced concrete precast beam respectively; due to the fact that the adjustable locating connecting pieces transversely and longitudinally move relative to the C-type steel sliding grooves, transverse and longitudinal moving adjustment and locating of the adjustable locating connecting pieces on the upper surface and the lower surface of the bearing table of the reinforced concrete precast beam can be achieved, prefabricated wall boards are correspondingly embedded into grooves in two ends of the upper adjustable locating connecting piece and the lower adjustable locating connecting piece respectively, and rapid locating and mounting of the assembled building wall boards in the prefabricated beam can be achieved.

The invention provides a wall panel hoisting tool and method. The wall panel hoisting tool comprises a hoisting fixture and a corner protector; the hoisting fixture comprises a clamping main body anda hoisting ring arranged at the top of the clamping main body; a first clamping groove is formed in the clamping main body; and a second clamping groove is formed in the corner protector. The wall panel hoisting method comprises the steps that the hoisting fixture is fixed to the top of the wall panel, and the corner protectors are mounted at the corners of the two sides of the bottom of the wallpanel correspondingly; the wall panel is erected in the short edge direction and is lifted; after the wall panel is vertically hoisted, the corner protector is dismounted; the wall panel is conveyed to a to-be-mounted position of the wall surface, and the wall panel is mounted on the wall surface; the hoisting clamp is dismounted; and all the steps are repeatedly executed until hoisting of all thewall panels is completed. According to the wall panel hoisting tool and method, the burden of a crane is relieved, the hoisting efficiency of the wall panel is effectively improved, the constructionperiod is shortened, the flatness of the bottom of each wall panel is controlled, and the construction quality is improved.

The invention discloses an external wall neck construction method of the underground cast-in-situ concrete structure, which includes the following steps: (1) arranging reinforced bars, wall body external steel bars and wall body internal steel bars on a bedding course, arranging a first exterior sheathing composed of a multilayer board and a square timber outside the wall body external steel barsin the method of external suspended form supporting formwork; (2) arranging the first exterior sheathing composed of the multilayer board and the square timber inside and fixedly connecting with the wall body internal steel bars, arranging a water-stopping steel plate between the wall body external steel bars and the wall body internal steel bars; (3) casting the concrete and finishing the underground cast-in-situ concrete structure external wall neck construction. The method enables a calendering operation of the upper surface of a foundation plate through surface rolling mechanically or manually, and enables the wall foot of the wall neck to be conveniently rolled to achieve the process requirement of one-step operation of casting and rolling together and the effect of exposed concrete.The method is easy, practical and economic, and the flatness can be controlled.
