The invention discloses an illuminating angle-adjustable illuminating lamp for a construction site. The illuminating lamp comprises a supporting plate, a fixed bracket, a supporting vertical rod, a rotating seat, a first driving gear, an annular rack, fixed vertical plates, an illuminating lamp body and a supporting frame, wherein a supporting sliding block is rotatably arranged in the rotating seat; the bottom end of the supporting vertical rod is fixedly connected with the middle top end of the supporting sliding block; the annular rack which meshes with the first driving gear is fixedly mounted at the top of the supporting plate; the fixed vertical plates are symmetrically and fixedly mounted at the bottom of the supporting plate; supporting rods are rotatably arranged on the fixed vertical plates; the supporting frame is fixedly mounted on the supporting rods; the illuminating lamp body is fixedly arranged on the supporting frame; and a second driving motor used for driving the supporting rods to rotate is fixedly mounted at the left end of the supporting plate. According to the illuminating lamp, the structure is simple and reasonable, mounting is convenient, the illuminatingangle of the illuminating lamp body is convenient to adjust, convenience is brought to the construction site, the utilization effect is good, and the illuminating lamp deserves popularization.

The invention provides a telescopic connection structure for plates. The structure comprises a first plate and a second plate and is characterized in that the first plate is equipped with a first connection end; unfixed connection holes at equal instances in N rows and M lines are arranged at the first connection end, wherein N is larger than or equal to 1 and M is larger than or equal to 2; a second connection end is arranged on the second plate and equipped with connection holes in N rows and P lines, wherein P is larger than or equal to 1 but smaller than or equal to M; the first connectionend and the second connection end are partially overlapped together in order to form an overlap region; each connection hole in the overlap region is aligned at one corresponding unfixed connection hole in order to form a pair of installing holes; and detachable screws penetrate through each pair of installing holes so that the first plate and the second plate are detachably and fixed connected.When the size of the connection structure needs an adjustment, the size of the overlap region is adjusted; therefore, connection holes are aligned at unfixed connection holes in different lines and the first plate and the second plate are detachably and fixedly connected through the detachable screws. Therefore, the connection structure is telescopic.

The invention provides a telescopic side wall assembly and a telescopic lift car. The telescopic side wall assembly comprises four side wall adjusting pieces, three side walls and a door side wall. The four side wall adjusting pieces are the same in structure and are each provided with a first connecting plate and a second connecting plate which are integrally formed and vertically arranged. The first connecting plates and the second connecting plates are each provided with N rows and M columns of equidistant indefinite connecting holes, wherein N is larger than or equal to 1, and M is largerthan or equal to 2. According to the telescopic lift car, the telescopic side wall assembly is arranged to achieve enlargement or reduction of the lift car, the lift car can adapt to shafts of different sizes, multiple purposes are achieved through one lift, building construction is greatly facilitated, the building cost is saved, using and mounting are convenient, and the structure is stable andreliable.

The invention relates to a ceramic tile adhesive with waterproof tile tiling function, which comprises 10-20 parts of Wacker 316 rubber powder, 10-20 parts of Wacker 8031H rubber powder, and 1-5 parts of cellulose ether according to parts by weight , 0.5 to 3 parts of polypropylene fiber, 2 to 8 parts of water repellent, 1 to 5 parts of defoamer, 0.5 to 4.5 parts of water reducing agent, 1 to 3 parts of wood fiber, 400 to 500 parts of Cement, 250-350 parts of high-quality quartz sand of 70-100 mesh, 100-200 parts of high-quality quartz sand of 100-150 mesh, 30-80 parts of high-quality quartz sand of 150-200 mesh and 200-400 parts of water. The present invention integrates various excellent performances and integrates waterproof tiling, which on the one hand saves costs, and on the other hand solves the problems of tile hollowing and brick falling, and is more conducive to building construction. The invention also enables the original product to simultaneously have the functions of tiling and caulking and waterproofing without affecting the construction performance, and improves the strength, elasticity, water resistance and corrosion resistance of the original product.
