A computer cable sorting device includes a base. A plurality of universal wheels are movably mounted on the bottom surface of the base, vertical first lifting bar groups are fixedly installed at the front and rear ends of the base top respectively, each first lifting bar group is composed of two first lifting bars, two first lifting bars in each group of first lifting bars are respectively locatedon both sides of the base, two first lifting bars in each group of first lifting bars are fixedly connected with each other through a horizontal first connecting bar, and vertical third lifting barsare fixedly installed on both sides of the top edge of each first connecting bar. A long strip block and a square block are fixedly connected through a first telescopic bar, so that that square blockcan be prevented from rotate with the screw bar, thereby limiting the angle of the square block. The spring always has a downward thrust force on one end of the support bar, so that the rack can be supported when not in use, the rack dropping is avoided from affecting the movement of the long bar, and thus the device is convenient in use.

The invention discloses a building roof construction process. A construction roof comprises a roof structure plate, a parapet wall and a roof surface layer, wherein the parapet wall is arranged above the roof structure plate, the roof surface layer is paved on the roof structure plate, a roof exhaust system is arranged on the construction roof and comprises a plurality of first horizontal exhaust pipes, the first horizontal exhaust pipes are respectively laid in a slope finding layer or a heat insulation layer in the roof surface layer, two ends of each first horizontal exhaust pipe are respectively connected with a vertical exhaust pipe, and the vertical exhaust pipes are embedded in the side walls of the parapet wall and a discharge flue or the side wall of an exhaust passage. The construction process of a construction roof comprises the steps of 1, surveying and setting out; 2, parapet wall, discharge flue and exhaust passage construction; 3, horizontal exhaust pipe positioning installation; 4, exhaust pipe connection; 5, roof surface layer construction; and 6, rigid protecting layer mesh division and caulking construction. The construction process has the advantages that the steps are simple, the operability is high, the realization is convenient, in addition, the work efficiency is high, the construction effect is good, and the construction quality of the construction forming building roof can be effectively ensured.

The invention belongs to the technical field of engineering technical urban rail transit construction, and particularly relates to an urban railway curved section track panel preparing method. The method comprises the following steps that the state of track panels of a track is restored, sleepers are laid, the stagger amount of track panel rail joints is prefabricated, the curve shortening amount is calculated, the shortening amount between any points of a transition curve is calculated, the transition curve shortening amount is calculated, the curve section total shortening amount is calculated, the stagger amount of track panel rail joints is calculated in a linear state or in a curve state, and the spacing distribution of the sleepers is calculated. Compared with the prior art, the method has the advantages that configuration data of the track panels are accurate, making and assembling of the track panels are convenient, simple and accurate, the problem that rail gaps are large after on-site assembly of the track panels is conducted is avoided, impact damage to railheads conducted by rail cars is reduced, shortened rails made by a factory are not used, the problem that rail sawing is needed in the curve is avoided, the waste of raw materials is reduced, the cost is saved, and the arrangement of the sleepers on the curve is regular, uniform, attractive and free of inclination.

The computer cable arrangement device includes a base, several universal wheels are installed on the bottom surface of the base, and a set of vertical first lifting rod groups are respectively fixed on the front and rear ends of the top of the base, and each group of first lifting rod groups consists of two Composed of first lifting rods, the two first lifting rods in each group of first lifting rods are respectively located on both sides of the base, and the two first lifting rods in each group of first lifting rods pass through a horizontal The first connecting rods are fixedly connected, and the two sides of the top edge of each first connecting rod are respectively fixedly installed with vertical third elevating rods. The long block and the square block are fixedly connected by the first telescopic rod, which can prevent the square block from rotating with the screw rod, thereby limiting the angle of the square block. The spring always has a downward thrust on one end of the support rod, so that the rack can be supported when not in use, so as to prevent the rack from falling and affect the movement of the long bar, which is more convenient in use.
