The invention discloses an enclosure structure for building construction. The enclosure structure for building construction comprises a base (1) capable of being fixed on the ground. The two ends of the base (1) are each provided with a positioning rod (2) which is vertically in clearance sliding fit with the base (1). A baffle (3) is arranged on the top surface of the base (1). Positioning seats (4) are arranged near the two ends of the positioning rods (2) correspondingly. An oblique supporting rod (5) is arranged on each positioning seat (4) and matched with the positioning seat (4) in a rotating connection mode. The two sides of the upper portion of the baffle (3) are each provided with a sliding groove (6) corresponding to the oblique supporting rod (5) on the adjacent side. The other end of each oblique supporting rod (5) extends into the corresponding sliding groove (6). The enclosure structure for building construction is simple, convenient to use, capable of freely resisting wind coming from the forward direction and the reverse direction, reliable in supporting structure, meanwhile, flexible in overall protecting structure, smaller in occupied area, and suitable for being popularized in the field.

The invention relates to a special vehicle body for rapid container transportation. The special vehicle body for the rapid container transportation is characterized by comprising an intermediate beam assembly, a pair of side beam assemblies, a central beam, a pair of double-lock beam assemblies, a pair of pillow-posterior monolock supporting structures, a pair of pillow beam assemblies, a pair of end beam assemblies and a pair of pillow-anterior monolock supporting structures. According to the special vehicle body for the rapid container transportation, nutation rotational inertia of a vehicle body structure can be effectively increased under the condition that the requirements of the vehicle length are met and accordingly the dynamic stability of a vehicle during high speed driving is improved; the problem that vertical stiffness of the vehicle body is reduced due to that a vehicle distance is extended is solved; meanwhile the end portions of intermediate beams are provided with lower tool holder structures and accordingly the height requirements of buffer installation of a vehicle coupler can be met; the number of vehicle body loaded containers is matched reasonably, meanwhile loading of multiple types of containers in the same vehicle can be achieved, and accordingly the number of vehicle length effectively loaded containers and the transportation efficiency are improved and waste of the vehicle length space is reduced. The special vehicle body for the rapid container transportation can be widely applied to vehicle manufacturing of the rapid container transportation.

The invention discloses an adjustable gob-side entry retaining wall with initial active and later buffering support and an implementing method thereof. The adjustable gob-side entry retaining wall with initial active and later buffering support and the implementing method thereof are mainly accomplished through the mode of completing prefabricating of components above a well and conducting masonry construction in a lane. Wall components mainly comprise a bedding block of a U-shaped structure, a lifting support block of a T-shaped structure, a friction crush block of a triangular structure, and a contractible crush block. The gob-side entry retaining wall has the advantages of being simple and reasonable in structure, good in supporting effect, adjustable in wall height, convenient to adjust, and strong in a adaptability; the main components used by the wall are all prefabricated above the well, intensity is guaranteed and quality is reliable. The implementing method is simple and convenient in operation, and a single hydraulic prop can be relied on to achieve wall position adjustment and active support can be provided by the single hydraulic prop to help cut off a lane gob side top plate; the wall is contractible so that pressure buffering function can be achieved; the accomplished gob-side entry retaining wall with initial active and later buffering support can adapt to the pressure change law of the gob-side entry retaining top plate.

The invention discloses a family table tennis table, which comprises two ball tables with the same structural size, each table includes a bottom frame and an electric lifting mechanism installed on the bottom frame, the top end of the driving rod of the electric lifting mechanism is fixed There is a top frame, the table is hinged on the top frame, and the top frame and the table have a gas spring to make the table vertical when they are in a natural stretch state; the top frame and the table have compressed gas springs and then lock when the table is horizontal The elastic buckle between the top frame and the table board; there are two male and female buckle devices for fastening at the junction of the two table boards; there are four universal wheels on the bottom frame; the front end of the ring of the male buckle The arc grooves on the fan-shaped block and the female buckle are fitted and locked with the arc bars. The height of this table tennis table is electrically adjustable, and the single-player practice table and double-playing table are convenient and labor-saving; when not in use, the elastic buckles of each table are disengaged so that the table boards of the two tables are in a vertical state to save storage. space.

The invention provides a sunlight greenhouse utilizing solar gas flow to generate electricity, relating to the technical field of renewable energy utilization. The top of the greenhouse is formed by continuous conical greenhouse roofs. An overturning plate is arranged between two adjacent conical greenhouse roofs. One end of the overturning plate is connected to a rotary shaft. One end, connected to the rotary shaft, of each overturning plate is further connected with a counterweight rod, on which a counterweight block is arranged. Each conical greenhouse roof is composed of a dayside and a nightside. The gradient of each nightside is larger than that of each dayside.The sunlight greenhouse utilizing solar gas flow to generate electricity has following beneficial effects: due to the fact that the roof is designed to be a conical surface, snow falling down on the roof can slide down to the overturning plate at the bottom by gravity effect; when snow on the overturning plate is accumulated at certain weight, one end of the overturning plate can be overturned downwards such that accumulated snow drops down into the greenhouse; and by thawing and vaporizing accumulated snow of the greenhouse into vapor, thermal gas flow can be further formed.
