Abstract
The invention relates to a treatment method for a horizontal construction joint of concrete walls. The treatment method comprises the steps that (1) when the pre-cast concrete wall is constructed, a split bolt is embedded into the portion 150 mm away from the construction joint to be reserved, and meanwhile, the upper portion of the pre-cast concrete wall is cast to form a concave top surface; (2) a formwork of the pre-cast concrete wall is removed, a line is snapped at the two ends of the concrete concave top surface, the two ends are ground flat through an angle grinder to remove burrs, and double-faced adhesive tape is stuck to the portion, between the horizontal construction joint and the split bolt, of the pre-cast concrete wall; (3) a connecting formwork is installed, the lower half portion of the connecting formwork is fixed to the spit bolt, and a row of split bolts are additionally arranged on the upper half portion, 150 mm away from the horizontal construction joint, of the formwork; (4) a formwork of the post-cast concrete wall is installed above the connecting formwork, and then treatment of the horizontal construction joint of the concrete walls is completed. The method is easy to implement and reasonable in design, saves time and labor and effectively improves the construction quality of concrete.
Description
Technical field
The invention belongs to concrete wall construction field, especially a kind of processing method of concrete wall horizontal construction joint.
Background technology
In building operations, cast-in-place concrete wall is a kind of common member, especially some public buildings are as library, museum, conference and exhibition center etc., it is thick and tall and big that concrete wall often design, and construction quality requires high, when construction, be once difficult to moulding by casting, at this moment just need to stay and establish horizontal construction joint at twice or repeatedly cast.If horizontal construction joint place deals with improperly, when wall construction, there will be the phenomenons such as swollen mould, stream slurry, faulting of slab ends in the above, affect normally carrying out of concrete construction quality and later process.Way be in the past below concrete wall body construction complete after, form removal, install according to a conventional method top wall form, not firm in the reinforcing of horizontal construction joint, cause the problems referred to above.Or below wall form do not remove, continue top template and install and construct, the disposable input amount of template is large like this, cannot have enough to meet the need.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of processing method of concrete wall horizontal construction joint is provided, this processing method is simple to operate, reasonable in design, time saving and energy saving, has effectively improved concrete construction quality.
The present invention solves its technical problem and is achieved through the following technical solutions:
A processing method for concrete wall horizontal construction joint, its processing method comprises the steps:
(1), in the time of the first fluid concrete wall of construction, apart from staying the pre-buried split bolt of the 150mm of constuction joint place of establishing, simultaneously by first fluid concrete wall top cast formation spill end face;
, the template of removing first fluid concrete wall, polish at concrete spill end face two ends snap the line and with angle grinding machine, remove burr, and paste double faced adhesive tape on the first fluid concrete metope between horizontal construction joint and pre-buried split bolt;
, install connect template, template Lower Half and pre-buried split bolt are fixed, the first half adds row's split bolt again, also apart from horizontal construction joint 150mm;
, connect install above template after the template of fluid concrete wall, concrete wall horizontal construction joint is disposed.
Advantage of the present invention and beneficial effect are:
The processing method of these concrete wall horizontal construction joint, (1) its processing method comprise the steps:, in the time of the first fluid concrete wall of construction, apart from staying the pre-buried split bolt of the 150mm of constuction joint place of establishing, the top cast of first fluid concrete wall is formed to spill end face simultaneously; , the template of removing first fluid concrete wall, polish at concrete spill end face two ends snap the line and with angle grinding machine, remove burr, and paste double faced adhesive tape on the first fluid concrete metope between horizontal construction joint and pre-buried split bolt; , install connect template, template Lower Half and pre-buried split bolt are fixed, the first half adds row's split bolt again, also apart from horizontal construction joint 150mm; (4), connecting the template of above template, rear fluid concrete wall being installed, concrete wall horizontal construction joint is disposed, the present invention is mainly by adding double split bolt at constuction joint place, and first fluid concrete face is carried out to thin portion and processed to avoid seam crossing to occur running pulp, faulting of slab ends, uneven phenomenon, the present invention is simple to operate, reasonable in design, time saving and energy saving, effectively improve concrete construction quality.
Brief description of the drawings
Fig. 1 is concrete wall horizontal construction joint construction schematic diagram of the present invention.
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A processing method for concrete wall horizontal construction joint, its processing method comprises the steps:
(1), in the time of the first fluid concrete wall 1 of construction, apart from staying the pre-buried split bolt 2 of the 150mm of constuction joint place of establishing, simultaneously by first fluid concrete wall top cast formation spill end face 6;
, the template of removing first fluid concrete wall, polish at concrete spill end face two ends snap the line and with angle grinding machine, remove burr, and paste double faced adhesive tape 3 on the first fluid concrete metope between horizontal construction joint and pre-buried split bolt; Be conducive to install connect when template tight with the laminating of first cast wall;
, install connect template 4, template Lower Half and pre-buried split bolt are fixed, the first half adds row's split bolt again, also apart from horizontal construction joint 150mm; Connect template and will select the template that rigidity is large to make, with the double split bolt guarantee of work simultaneously template indeformable;
, connect install above template after the template of fluid concrete wall 5, concrete wall horizontal construction joint is disposed.Carry out postorder wall construction.
Claims (1)
1. a processing method for concrete wall horizontal construction joint, is characterized in that: this processing method comprises the steps:
(1), in the time of the first fluid concrete wall of construction, apart from staying the pre-buried split bolt of the 150mm of constuction joint place of establishing, simultaneously by first fluid concrete wall top cast formation spill end face;
, the template of removing first fluid concrete wall, polish at concrete spill end face two ends snap the line and with angle grinding machine, remove burr, and paste double faced adhesive tape on the first fluid concrete metope between horizontal construction joint and pre-buried split bolt;
, install connect template, template Lower Half and pre-buried split bolt are fixed, the first half adds row's split bolt again, also apart from horizontal construction joint 150mm;
, connect install above template after the template of fluid concrete wall, concrete wall horizontal construction joint is disposed.
