Description
Technical Field
The invention relates to the technical field of building construction, in particular to a construction process for reserving tie bars in a main body wall column structure.
Background
With the progress of human society, the requirements on the building functions are higher and higher, so that the reinforced concrete structure is widely applied to the modern buildings.
In reinforced concrete buildings, secondary structures such as non-masonry bodies are provided in addition to reinforced concrete structures such as load-bearing structures. Quality and potential safety hazards such as easy cracking of joints and the like often exist between a primary reinforced concrete structure and a masonry secondary structure. In order to prevent quality and potential safety hazards such as joint easy cracking often existing between a reinforced concrete structure and a masonry secondary structure, builders propose to bury the tie bar underground in the primary structure, and then lay the tie bar into the masonry wall, so that the connection between the reinforced concrete structure and the masonry secondary structure is firm.
How to solve the problem that how to accurately pre-embed the tie bars during the construction of the reinforced concrete vertical wall column structure is a choice before constructors. The method for pre-embedding the tie bars can be divided into a front-mounted fully-embedded tie bar, a front-mounted semi-embedded tie bar and a rear-mounted tie bar. The preposed fully-embedded tie bar has the advantages that the tie bar is well installed according to the design requirement, the tie bar is tied on a steel bar framework of the vertical wall column by adopting a folding method, and the vertical wall column is removed from a concrete finished product after the concrete pouring of the vertical wall column is finished and the form is removed. The binding tightness control is poor, deviation often occurs due to the influence of concrete blanking and vibration, the surface of a concrete finished product is seriously damaged, and even the tie bar cannot be used due to deviation. The preposed semi-embedded tie bar has the advantages that after the reinforced concrete vertical wall column structure template is erected, holes are drilled on the template according to design requirements, and then a part of tie bar (about 300 mm in length) is installed; and after the concrete pouring is finished and the formwork is removed, welding and lengthening the pre-embedded tie bars to form complete masonry tie bars. Its advantage is that pre-buried drawknot muscle position is accurate, does not damage concrete finished product, and its shortcoming is: the template is easy to damage and increases the cost, and the quality of the concrete is not easily affected because the wood chips are mixed into the vertical reinforced concrete wall column template after drilling and the cleaning is not thorough. The rear-mounted tie bar is characterized in that after concrete pouring and form removal are completed, the position of the tie bar is calibrated according to a design drawing, and then a hand-held electric drill is used for drilling holes and then chemical bar planting operation is carried out. Its advantages are precise locating of the tie bars and difficult control of the quality of bar planting operation.
