The invention belongs to the field of cultural relic protection, and particularly relates to oyster ash silt slurry for repairing hollow drums and cracks and anchoring of murals and a preparation method thereof. The invention aims to solve the problem of how to prepare reinforcing slurry more suitable for repairing hollow drums and cracks and anchoring of murals in the prior art. The preparation method is provided and comprises the following steps: roasting oyster shells at 900-1100 DEG C for 2-3 hours, deliquescing, and finely grinding to obtain oyster ash; mixing the oyster ash and silt according to the mass ratio of 1: 3-1: 15, adding water, and stirring until slurry with the fluidity of 200-240 mm is obtained. The slurry disclosed by the invention is wide in raw material source and simple in formula, has relatively large porosity, relatively small contractibility and relatively good anti-aging performance after being solidified, completely meets the reinforcing requirements of hollow drums and cracks and anchoring of murals, and provides a novel material for repairing defective mural cultural relics.

The invention discloses a method and a device for SO files to call external functions. The method comprises the steps of getting memory addresses of the external functions which are needed to be called by the SO files, establishing mapping relations between specified functions and the obtained memory addresses, calling the specified functions from the corresponding memory addresses according to the mapping relations when the SO files need to call the specified functions. According to the technical scheme, when the SO files call the specified external functions, the calling process no longer depends on the memory addresses of the specified external functions provided by a system. The method and device are suitable for the SO files wrapped in a shell and meet the requirement of reinforcing the SO files.

The invention provides a head dragon component used for strengthening the head structure of building formwork, and relates to the technical field of building formwork. The head dragon component includes: an end plate and a head dragon body, and the end plate and the head dragon body are integrally formed and form a right angle to each other The end plate is provided with end plate teeth and end plate connection holes, and the end plate is provided with a plurality of equidistant rectangular connection holes, which can be connected with the end plate connection holes of the same model of the same type of dragon that are opposite to each other; the body of the head dragon is provided with The connecting holes of the template and the teeth of the end plate are provided with equidistant meshing teeth, and the convex and concave teeth have the same shape, and are arranged in dislocation and reverse connection. The two head dragon components can be equipped with reinforcement systems of different head thicknesses at the head formwork, so that the bending moments generated in all directions of the formwork head structure are offset by the head dragon's own structure and assembly system, and the strength of the three sides of the formwork head structure is enhanced. The mechanical synergy of the reinforcement components solves the technical defect of weak reinforcement mechanics at the corners of the formwork head structure existing in the prior art, and significantly improves the forming effect of the concrete components.

The invention belongs to the technical field of building materials, and in particular relates to a structure reinforcing material taking steel slag as aggregate. The material consists of cement, the steel slag, mineral slag powder, fly ash, zeolite powder, latex powder, cellulose ether, an antifoaming agent and a polycarboxylic acid water reducing agent. The steel slag is subjected to hot closed treatment; the problem that the common steel slag easily cause low stability of the material can be solved, and the solid waste in the steelmaking industry, namely the steel slag is recycled and efficiently utilized; the cost of the conventional cement-based reinforcing material can be reduced, and the material has higher construction property, mechanical property and durability; and the material has high compression strength, breaking strength and durability and low shrinkage, and is suitable for the reinforcing engineering of various buildings and bridges.

The invention relates to an external prestressed reinforcing device for a six-four type railway military beam, which includes a triangular bracket, a connecting body and a prestressed cable; Rod connection; prestressed cables include double-ear anchor ends, tension ends and steel strands; connectors include top plates and bottom plates; tension bolts and single ears A are fixedly installed on the top surface of the top plate; tension ends and tension ends The bolts are fixedly connected, and the anchor ends of the double ears are connected with the corresponding upper and lower triangular brackets; the present invention installs the connecting body and the triangular bracket on the upper chord of the six-four beam, and installs the prestressed cable between the connecting body and the triangular bracket, so that Each node of the upper chord is prestressed vertically upward to offset the vertical unfavorable load caused by the self-weight of the six-four beam and the passing of the train, thereby reducing the deflection of the six-four beam and improving the force condition of the vertical bar and other members .
