Description
Technical Field
The utility model relates to a construction technical field particularly, relates to a wall post template axis position and straightness detector that hangs down.
Background
In a conventional cast-in-place frame and frame-shear wall structure system, wall and column formworks are generally installed and reinforced by adopting a steel-wood combined formwork, a combined steel formwork or a sizing aluminum film process, and the formwork system is formed by combining a formwork panel, primary and secondary keels, split bolts and inclined supports. After the wall and column templates are installed and reinforced, according to the construction quality acceptance standard requirements, the actual measurement and inspection are carried out on the template axis position, the perpendicularity, the elevation size, the surface flatness and other items. In the prior art, the axis position and the verticality of the wall and column template are generally detected by the following 4 methods:
(1) and (3) line drop detection method: the clearance gauge made of wood strips is clamped between a main keel at the upper part of a template and the template, a line drop is hung downwards on the clearance gauge, the vertical point of the line drop aligns to a control line which is 200-300 mm away from the side line of the template, the distance between the hanging line and the template is measured by dividing an upper, a middle and a lower three points by a measuring tape, the lower distance is used as a base number, the axis position and the verticality of the template are compared through the self-verticality performance of the line drop, and a schematic diagram of detecting the verticality by a line drop method is shown.
The detection method needs at least two persons to operate, detection personnel on the upper portion need to climb a ladder or climb a formwork to perform climbing operation, the number of detection points determines the climbing times, the working strength is high, the movement is inconvenient, the detection speed is low, the working efficiency is low, and potential safety hazards of climbing and falling exist at the same time. In addition, in the open-air operation environment, the verticality of the suspension wire is greatly interfered by wind power, the stability is insufficient, the influence of human factors is obvious, the detection result is inaccurate directly, the size deviation of the formed component is overlarge, and the quality of the cast-in-place structural engineering is influenced.
(2) A guiding rule detection method comprises the following steps: adopt 2m or 3m guiding rule to detect, but the perpendicular pointer graduation apparatus of utilizing guiding rule itself can directly read the straightness numerical value that hangs down, but is used for detecting the template straightness that hangs down of establishing and then the effect is bad, because of the restriction of template vertical and horizontal fossil fragments, the unable direct contact template surface of guiding rule detects. The improved method that the upper transverse rod and the lower transverse rod are additionally arranged at the two ends of the guiding rule and the template is indirectly contacted is also available on the site, but the method can only detect the verticality of the template and cannot have the function of checking the axis position, the length of the guiding rule is fixed, the guiding rule is difficult to be universal for templates with various layer heights, and meanwhile, the guiding rule does not have the detection capability and needs manual ascending matching for any height in the middle of the template, so that the defects of labor cost, low speed and low work efficiency and potential safety hazards exist. The schematic diagram of the detection of the verticality by the running rule method is shown in figure 2.
(3) Theodolite detection method: the template axis position and perpendicularity are detected through a theodolite by adopting a parallel projection method, a template center point A, B is firstly released on a base layer, an ink line is popped up, then parallel lines A1B1 of AB are measured, the distance between the parallel lines A1B1 is 1-1.5 m, the theodolite is placed at a B1 point and is aligned with the A1, a staff for detecting holds a wooden ruler above the template to be horizontally placed, the ruler zero point is aligned with the center position between side molds, the theodolite looks up the wooden ruler to observe the reading, the difference between the reading and the distance between the two points A, A1 is the template perpendicularity and axis position deviation value, and a schematic diagram for detecting the perpendiculari.
The detection method is most complicated, needs to erect the theodolite for multiple times, and also needs manual ascending matching. In addition, the site operation conditions are complex and various, and are influenced by the top plate support and the inclined strut, so that the theodolite cannot always look through completely, and the actual effect of quality detection cannot be achieved. The method integrates various defects of a line drop method and a running rule method, has an unsatisfactory detection effect, and is not generally adopted on site.
(4) Infrared detection method: the laser demarcation device is arranged at the end part of the template for leveling and centering, a vertical line is aligned to a control line which is 200-300 mm away from the side line of the template, a closed vertical infrared ray is projected after the device is started, the rotating device adjusts the infrared ray to be parallel to the central line of the template, the measuring tapes are used for respectively measuring the distance from each part of the template to the infrared ray, and the axis position and the vertical degree of the template are detected by utilizing the line weight principle.
When the laser demarcation device is used for an indoor environment or a wide space constructed at night, the laser demarcation device has the advantages of intuition, convenience and quickness, but under an outdoor operation environment, particularly when the laser demarcation device is used in sufficient sunshine, the defects of difficulty in light visibility, unclear infrared rays and the like exist, the infrared ray path width is increased along with the lengthening of the sight distance, and the accuracy of a detection result is influenced. Meanwhile, when the verticality of the template is measured, if the upper, middle and lower 3 measuring points at the same position are not on a vertical line, the detection result will be deviated. In addition, although the detection speed is improved, the problem that the detection personnel frequently climb up and climb cannot be solved.
