The invention discloses an LED (light emitting diode) panel lamp and a frame thereof. The frame is spliced by two first frame section bars and two second frame section bars through four corner joints; the two second frame section bars are arranged oppositely, each corner joint is provided with a first plugging arm and a second plugging arm; the root part of each first plugging arm is connected with the corresponding second plugging arm, the head part of each first plugging arm is inserted into a first jack of the corresponding first frame sections bar, the top of each first plugging arm and the top inner wall of the corresponding first jack are provided with at least three contacts which are not in the same line, and the bottom of each first plugging arm and the bottom inner wall of the corresponding first jack are provided with at least three contacts which are not in the same line; the head part of each second plugging arm is inserted into a second jack of the corresponding second section bar, and is connected with the same method; the root part of each first plugging arm is larger than the head part of the first plugging arm, and the root part of each second plugging arm is larger than the head part of the second plugging arm. The LED panel lamp and the frame thereof adopting the technical scheme have the advantages that the structure is simple and reasonable, the assembly and debugging are convenient, the yield is high, and the productivity is high.

The invention discloses a precast concrete splicing component and a preparation method thereof. The precast concrete splicing component comprises a first splicing part provided with at least one first splicing face, a second splicing part provided with at least one second splicing face, connecting tenons with base bodies fixed into the first splicing part and the ends protruding out of the first splicing faces, isolation boards with one sides connected with anchor bars, and shearing force locking keys installed in first shearing force key installation cavities and second shearing force key installation cavities. No bolt hole or operation hole needs to be formed in the precast concrete splicing component, and the situation that the section of the precast component is weakened by various hole channels required for splicing and connecting construction of the precast concrete splicing component is eliminated. By the adoption of the precast concrete splicing component, under the condition that the section of the precast concrete component is not weakened, the highest splicing speed can be reached. The splicing accuracy of the precast concrete splicing component is high.

The invention provides an environment-friendly concrete composite floor slab. The environment-friendly concrete composite floor slab is characterized in that the environment-friendly concrete composite floor slab comprises a connecting steel bar support, a bottom plate steel bar support, four connecting steel bars, a bottom plate steel bar, a tie steel bar, a top steel bar, anti-shearing keys, anouter frame, positioning steel bars, positioning pipes, stirrups and a bottom plate steel bar casing pipe; outer frame connecting holes are formed in the two ends of the outer frame, outer frame positioning holes are formed in the two sides of the outer frame, and the anti-shearing keys are arranged on the inner sides of the connecting steel bars and the bottom plate steel bar; the bottom plate steel bar and the upper sides and the lower sides of the connecting steel bars are subjected to concrete pouring to form composite floor slab concrete layers; the positioning pipes penetrate into the space between the composite floor slab concrete layers through the positioning steel bars for fixed connection; the stirrups are arranged on the outer sides of the top ends of the four connecting steelbars in an embracing mode and fixedly connected with the connecting steel bars. Distributed bars in the composite floor slab are distributed evenly, the steel bars are aligned accurately, the structure is simple, the manufacturing process is easy and convenient, manufacturing is easy, the structure strength is high, and construction and mounting are easy.

The invention discloses a planter capable of achieving water storage and drainage. The planter comprises base plates and a fence, wherein insertion grooves are formed in the peripheral edges of the upper end of each base plate, the fence is inserted into the insertion grooves, water storage cells distributed in a latticed mode are arranged on each base plate, first through holes are formed in the positions where the water storage cells distributed in the latticed mode on each base plate intersect, the through holes are not lower than the water storage cells, clamps are arranged on the two lateral sides of each base plate, clamping grooves matched with the clamps are formed in the other two lateral sides of each base plate, and in this way, any two base plates can be clamped together through the clamps and clamping grooves. According to the planter, the base plates, the fence and the connecting rods are all designed to be of splicing structures so that the size of the planter can be adjusted freely as needed; furthermore, the clamping and splicing structures are simple and reliable, the water storage cells and through holes of the base plates can meet the requirements of plants for water storage, water drainage and ventilation, and automatic watering can be achieved. The planter is especially suitable for roofs, balconies, yards, streets and the like.

The invention discloses a bolt pin-type crossed tenon tooth precast concrete unit and a preparation method thereof. The bolt pin-type crossed tenon tooth precast concrete unit comprises a first splicing part, a second splicing part, segregation boards and shearing force locking bolt pins. Tenon teeth and mortises are arranged at the splicing ends of the first splicing part and the second splicing part at intervals. Each tenon tooth is a prism with the trapezoidal cross section. The segregation boards are provided with folding structures consistent with the tenon teeth and the mortises of the second splicing part. Bolt pin holes are formed in the positions, corresponding to bolt pin mounting cavities of the second splicing part, of the segregation boards. The shearing force locking bolt pins are mounted in the first bolt pin mounting cavities and the second bolt pin mounting cavities in a penetrating mode. The bolt pin-type crossed tenon tooth precast concrete unit is simple in structure. The precision requirement for formworks is low at the prefabrication stage. After prefabrication is completed, precision of joint cracks between precast parts is high, and no subsequent repairing treatment is required after splicing is completed. In addition, the highest splicing speed can be realized under the condition of not decreasing the cross section of the precast concrete unit.
