The application provides a brick-concrete complex structure reinforcing method, and belongs to the technical field of building construction. The brick-concrete complex structure reinforcing method comprises the following steps: erecting support in the interior and middle position of the brick-concrete complex structure, excavating the added foundation contour of the brick-concrete complex structure, releasing the foundation cutting line and adding the outer contour line of the foundation, chiseling away the strip foundation and the rubble foundation by using the static cutting mode, installing the design drawing reserved pile hole on the brick-concrete complex structure, fixing and connecting the vertical main reinforcement of the buttress column with the structural reinforcement on the brick-concrete complex structure, opening the shear key hole, fixing and connecting the ring beam ring reinforcement with the original wall body of the brick-concrete complex structure, fixing the buttress column and the beam on the brick-concrete complex structure in sequence, and pouring the concrete. The method can solve the problem that the existing reinforcing method of the brick-concrete complex structure greatly disturbs and damages the wall to be reinforced and does not change the stress mode of the original structure form.

The invention relates to a built-in buttress structure and a construction method, the built-in buttress structure comprises a column body component and a top beam component, the column body component is assembled in the height direction of a wall body, and the top beam component is connected with the column body component and used for being assembled in the width direction of the wall body. The construction method comprises the following steps: determining reinforcing areas of a column body component and a top beam component on a wall body; grooving operation is carried out on the reinforcing area so as to form an assembling groove; popping up an arrangement position line in the reinforcing area; and according to the arrangement position line, arrangement pouring is carried out to form the column body component and the top beam component. According to the built-in buttress structure and the construction method, the wall needing to be repaired is reinforced, the wall is prevented from being damaged in the repairing process, and safety and stability in the repairing process are improved.

The utility model provides a brick-concrete house transformation and reinforcement structure, and belongs to the technical field of brick-concrete structure building transformation and reinforcement. The structure comprises a brickwork outer wall, foundation beams are arranged at the bottoms of the inner side and the outer side of the brickwork outer wall, unloading beams are further arranged at the bottom of the brickwork outer wall, the unloading beams transversely penetrate through the brickwork outer wall and are connected with the foundation beams, and the inner side of the brickwork outer wall is reinforced through a cement mortar surface layer; the structural columns penetrate through the floors and extend to the bottom of the roof panel, and strip-shaped foundations are arranged at the bottoms of the structural columns; the structural beam plates are arranged on all the layers, the ends of the structural beam plates are connected with the structural columns or the masonry outer walls, and buttress columns are arranged at the ends, connected with the masonry outer walls, of the structural beam plates and extend downwards to the foundation beams along the masonry outer walls. On the premise that the external facade of the bare brick wall of an original building is not changed, the bare brick wall is transformed into a reinforced concrete frame structure for stress, and the anti-seismic performance, ductility and integrity of the building structure are improved.

The invention relates to the technical field of building structure reinforcement and transformation, in particular to a supporting structure for brick masonry wall holing and a construction method.The supporting structure comprises a plurality of pilasters vertically arranged on the two sides of a wall and used for being arranged along the two sides of the wall at intervals so as to provide longitudinal supporting; the shoulder beams are located at the holing position of the wall body and attached to the top face of the holing position so as to support the wall body; the supporting beam extends in the length extending direction of the wall body and is connected with the shoulder beam in a matched mode to form a supporting frame, and the end of the supporting beam is fixedly connected with the pilaster. According to the supporting structure, the permanent reinforcing component and the construction process are combined, and the upper load can be continuously and reliably borne and transmitted in the holing construction period and after holing construction is completed. The supporting structure disclosed by the invention is used for guaranteeing the stability and the reliability of the wall body transformation process and the whole transformed structure, not only guarantees the reliability of the wall body structure, but also can improve the construction treatment efficiency, is compatible with hole-opening transformation of various sizes, and is flexible and convenient to support.

This utility model discloses a decorative false column, including a false column body, a concrete structural beam, and connectors. The false column body is connected to the concrete structural beam via connectors. The connectors include sidewall steel plates and bolts, with multiple through holes on the sidewall steel plates. The bolts pass through the through holes and connect to the false column body. When the sidewall steel plates are mounted on the false column body, the connectors can move vertically. The beneficial effect of this utility model is that it can reduce the risk of cracking at the connection node between the top of the false column and the structural beam.

The application discloses a construction method of full-precast assembly side wall door for underground structure, which comprises the following steps: 1, pouring the lower frame beam and reserving the lower groove; 2, setting the rubber waterstop in the lower groove and clamping all the temporary walls of the precast plates; 3, sequentially setting the rubber waterstop and the steel formwork for pouring the upper frame beam at the upper end of all the temporary walls of the precast plates; 4, tightening the gap between the steel formwork and the corresponding temporary wall of the precast plate by the pre-pressing bolt to press the corresponding rubber waterstop; 5, pouring the two side wall columns and the upper frame beam; 6, setting the steel plate which is connected with the corresponding temporary wall of the precast plate, covers the height of the corresponding temporary wall of the precast plate and extends along the width direction of the door frame structure; 7, filling the corresponding gap position with butter; 8, after the excavation of the foundation pit is completed, all the temporary walls of the precast plates are removed and recycled. The application realizes the chiseling-free and convenient dismounting of the side wall door of the underground structure and makes up for the defects of the prior art.

This invention discloses a method for positioning, checking, and installing inclined screws on the foundation of a dome tensioning platform, belonging to the field of building construction. The positioning and checking method employs two coordinate transformations: the coordinate system is transformed to have the center point of the foundation on the dome as the origin, the direction parallel to the central axis of the screw as the H-axis, and the direction perpendicular to the central axis of the buttress column as the B-axis; then, the C-axis direction is determined according to the right-hand rule. Under this coordinate system, the installation position of the screw can be visually judged as qualified. The installation method uses the positioning and checking method of this invention, installing no less than four support rods, two first angle steels and two second angle steels, as well as a reinforcing frame and reinforcing bars on the dome pouring layer to achieve the positioning and installation of the screw. This installation method is simple, reliable, and can quickly, conveniently, and accurately install the screw.
