1. A processing method after the door and window entrance reservation exceeds standard is characterized by comprising the following steps:

s1, drilling mounting holes on the wall surface with a gap between the concrete wall body and the door and window frame by using electric drills, wherein the mounting holes are respectively arranged in a row at two sides of the door and window frame and are arranged at intervals in the transverse and longitudinal directions;

s2, nailing reinforcing steel bar heads into the mounting holes;

s3, hanging a reinforcing mesh on the reinforcing steel bar head, and firmly binding the reinforcing mesh by using binding wires;

s4: and pressing dry and hard fine stone concrete into the gap between the concrete wall body and the door and window frame until the dry and hard fine stone concrete is flush with the door and window frame, and smearing edges and corners on the edges of the hole.

Technical Field

The invention relates to the related technical field of constructional engineering, in particular to a processing method after the reserved door and window openings exceed the standard.

Background

At present, in the building engineering construction, the required entrance to a cave of installation door and window all is before structural concrete pours, reserves out with the wooden box, and in order to prevent when concreting, the wooden box of concrete extrusion reduces door and window hole reservation size, can do the reservation size greatly usually, and this peripheral certain gap that can leave behind the door and window that just leads to the later stage to install. At present, plastering, filling and embedding ointment or silica gel is generally adopted for treatment, but certain problems generally exist, such as: the plastering layer is too thick and cannot be fixed, and small bricks cannot be built even if gaps are too small; the expansion coefficients of the door and window frame and the mortar material are different, and the problems of cracking, separation and the like of the door and window frame and the wall filling part can be caused when the door and window frame is vibrated by external force.

Disclosure of Invention

The invention aims to solve the problems, and provides a processing method after the door and window opening reservation exceeds the standard, which can well process the gap between the door and the window and the door and window opening, ensure the fixing effect of the door and window frame and avoid the problems of cracking and the like in the later period.

The invention solves the problems and adopts the technical scheme that:

a processing method after the door and window entrance reservation exceeds standard comprises the following steps:

s1, drilling mounting holes on the wall surface with a gap between the concrete wall body and the door and window frame by using electric drills, wherein the mounting holes are respectively arranged in a row at two sides of the door and window frame and are arranged at intervals in the transverse and longitudinal directions;

s2, nailing reinforcing steel bar heads into the mounting holes;

s3, hanging a reinforcing mesh on the reinforcing steel bar head, and firmly binding the reinforcing mesh by using binding wires;

s4: and pressing dry and hard fine stone concrete into the gap between the concrete wall body and the door and window frame until the dry and hard fine stone concrete is flush with the door and window frame, and smearing edges and corners on the edges of the hole.

Compared with the prior art, the invention adopting the technical scheme has the outstanding characteristics that:

through reinforcing bar and reinforcing bar net, make the concrete of packing closely combine with the wall body, guarantee that door and window frame is stable fixes in the door and window entrance to a cave of wall body, the coefficient of expansion of filling part and door and window entrance to a cave is the same, avoids the later stage to appear the fracture scheduling problem.

fig. 2 is a schematic view of the structure of the reinforcing bars and the reinforcing mesh in the embodiment of the present invention.

In the figure: a steel bar head 1; a reinforcing mesh 2; a wall body A; and a door and window frame B.

Detailed Description

The invention will be further illustrated by the following examples, which are intended only for a better understanding of the present invention and therefore do not limit the scope of the invention.

As shown in fig. 1 and 2, a method for processing a gap between a door and window frame and a wall includes:

s1, drilling mounting holes with the diameter of 8mm and the depth of 50mm on the gap wall surface of the concrete wall A and the door and window frame B by using electric drills, wherein the mounting holes are respectively arranged in a row at two sides of the door and window frame B and are arranged at intervals of 120mm in the transverse direction and the longitudinal direction;

s2, nailing the round 6 steel bar heads 1 with the length of 80mm into the mounting holes;

when drilling holes by using the electric drill, the distance between the reinforcing steel bar hole and the edge of the concrete wall body A at the hole opening is required to be not less than 40mm, so that the fixing effect of the reinforcing steel bar head 1 is ensured; reinforcing bar head 1 exposes in the wall 30mm so that ligature reinforcing bar net 2, has also avoided the later stage to appear rusty spot simultaneously, influences pleasing to the eye and installation quality.

S3, hanging round 6mm steel bar net sheets on the steel bar heads 1, and binding the cross-shaped parts of the steel bar nets 2 on the steel bar heads 1 by using binding wires;

s4: and pressing dry and hard fine stone concrete into the gap between the concrete wall A and the door and window frame B until the dry and hard fine stone concrete is flush with the door and window frame, and smearing edges and corners on the edges of the hole.

The method for processing the gap between the door and window frame B and the wall body A avoids infirm fixation of the filled concrete and the wall body B at the door and window opening, ensures that the door and window frame A is stably fixed on the wall body B at the door and window opening, ensures that the filling part has the same expansion coefficient with the door and window opening, avoids the problems of cracking and the like at the later stage, and further improves the door and window installation effect and the installation quality.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, which is defined in the appended claims.
