Abstract
The invention relates to a construction method of a basement wall without foundation joint bar; the method is characterized in that: step 1, familiarizing the specification and model of the wall steel bar and the longitudinal steel bar spacing; step 2, combining blanking software, optimizing nodes and wall reinforcing bars in the blanking software, and canceling wall joint bars reserved on a foundation and wall longitudinal steel bar joints of a previous floor; blanking according to the blanking list; and (3) binding the steel bars by combining a construction drawing, and taking a lateral temporary fixing measure after the conventional binding operation of the longitudinal steel bars of the wall is finished when the basic reinforcement of the project is a single-layer bidirectional reinforcement. The basement wall steel bar is removed from the foundation joint bar in the construction process of the foundation stage, and the traditional construction method is changed, so that the steel bar joint cost of the foundation joint bar and the wall longitudinal steel bar, such as the steel bar material cost of a binding joint, the steel bar threading labor cost of a straight thread joint and the material cost of a straight thread sleeve, is saved.
Description
Technical Field
The invention relates to the field of civil construction, in particular to a construction method of a basement wall foundation-free dowel.
Background
At present, in basement major structure basic stage work progress, the vertical reinforcing bar of wall body can be according to the specification interval of the vertical reinforcing bar of wall body according to drawing set regulation and conventional construction process in advance to keep somewhere corresponding basic dowel steel in the stage of basic reinforcement. The process of reserving the basic dowel bars has some problems. For example, the cost of producing the foundation reinforcing bars is additionally increased, and a series of costs such as whether the reinforcement joint processing of the foundation reinforcing bars reaches standards, manual spot-checking of the foundation reinforcing bars, and the like are increased.
Disclosure of Invention
The invention aims to overcome the problems and provides a construction method for directly inserting the longitudinal steel bars of the wall body into the foundation without the insertion of the foundation steel bars, so that the cost of the steel bar joint can be saved, and the quality risk caused by the steel bar joint can be avoided.
In order to achieve the above object, the present invention is realized by:
a construction method of a basement wall foundation-free dowel steel comprises the following steps:
step 1, carrying out technical planning in advance, and mastering basic information of basement engineering and specification type longitudinal steel bar spacing of wall steel bars, namely other accessory conditions by familiarizing with drawings;
step 2, combining Guangda, Luban or other computer-assisted blanking software, optimizing nodes and wall reinforcing bars in the blanking software, canceling wall joint bars reserved in a foundation and wall longitudinal reinforcing steel bar joints of the previous floor, and performing accounting and drawing;
step 3, performing bottom crossing on a steel bar operator on a construction site according to a steel bar blanking list, performing blanking according to the bottom crossing or the steel bar material list of a technical manager, and ensuring the accuracy of steel bar blanking;
step 4, combining the construction drawing to perform reinforcement binding operation, and when the foundation reinforcement of the project is a double-layer bidirectional reinforcement, performing conventional binding operation on the wall longitudinal reinforcement in the foundation according to the requirements of the drawing and the drawing; when the basic reinforcement of the project is a single-layer bidirectional reinforcement, a lateral temporary fixing measure is adopted after the conventional binding operation of the longitudinal reinforcement of the wall body is finished.
The construction method provided by the invention eliminates the foundation joint bars in the construction process of the basement wall steel bars in the foundation stage, changes the traditional construction method, and saves the steel bar joint cost of the foundation joint bars and the wall longitudinal steel bars, such as the steel bar material cost of binding joints, the steel bar threading labor cost of straight thread joints and the material cost of straight thread sleeves.

Fig. 3 is a schematic view of a lateral support structure.
Detailed Description
The invention is further illustrated by the following specific examples.
A construction method of a basement wall foundation-free dowel steel comprises the following steps:
step 1, carrying out technical planning in advance, and mastering basic information of basement engineering and specification type longitudinal steel bar spacing of wall steel bars, namely other accessory conditions by familiarizing with drawings;
step 2, as shown in fig. 1, combining Guangda, Luban or other computer-aided blanking software, optimizing nodes and wall reinforcing bars in the blanking software, canceling wall joint bars reserved in a foundation and wall longitudinal steel bar joints of a previous floor, and performing checking and drawing;
step 3, as shown in fig. 2, bottom crossing is performed on steel bar operators on a construction site according to a steel bar blanking list, blanking is performed according to bottom crossing or a steel bar material list of technical managers, and the accuracy of steel bar blanking is guaranteed;
step 4, as shown in fig. 3, performing reinforcement binding operation by combining construction drawings, and performing conventional binding operation on wall longitudinal reinforcements in the foundation according to the requirements of the drawing and the drawing when the engineering foundation reinforcements are double-layer bidirectional reinforcements; when the basic reinforcement of the project is a single-layer bidirectional reinforcement, a lateral temporary fixing measure is adopted after the conventional binding operation of the longitudinal reinforcement of the wall body is finished.
The construction method provided by the invention eliminates the foundation joint bars in the construction process of the basement wall steel bars in the foundation stage, changes the traditional construction method, and saves the steel bar joint cost of the foundation joint bars and the wall longitudinal steel bars, such as the steel bar material cost of binding joints, the steel bar threading labor cost of straight thread joints and the material cost of straight thread sleeves.
