Description
Technical field
The present invention relates to a kind of detection method in floor construction supporting template working hour more particularly to a kind of large span templates
The measurement method of arch camber.
Background technique
Currently, in the realm of building construction, concrete floor is mostly used template and is installed, with Architectural Structure Design now
Span it is increasing, also higher and higher to the required precision of supporting module arch camber, for large span template, intermediate position should have
Arch camber, not in place such as arch camber, after casting concrete, floor is likely to occur the downwarp of intermediate position part, influences building structure
Beautiful and safety.It to the detection method of arch camber is used by site operation personnel to template bottom scaffold position in the prior art
Steel ruler is detected, and detection is not easy, and testing result is inaccurate.
Publication No. CN108827232A Chinese invention patent application discloses a kind of longspan structure springing quantum and quickly surveys
Device and method is measured, which includes laser pick-off end, Laser emission end and the level set on shell；
The pedestal and limited block of Sopwith staff are set to scale blade bottom end and top, and sliding block is set to scale blade, and sliding block top surface and side are equipped with
Level and prism, Laser emission receiver are set to tripod.The measurement method is set at longspan structure both ends by tripod
Laser emission receiver is set, Sopwith staff erects the measuring point between two Laser emission receivers, moves sliding block along scale blade, works as cunning
The laser beam that block is moved to the transmitting of two Laser emission receivers passes through the prism of sliding block and terminates the time receiving by other side's laser pick-off,
It reads Sopwith staff scale and records；Successively subsequent each measuring point measurement, finally makes the difference two-by-two, obtains the springing quantum of longspan structure.It should
Apparatus structure is complex and costly, and many and diverse using the arch camber detection method operating process of the device, measurement point is more, computationally intensive,
Influence construction speed.
Summary of the invention
The purpose of the present invention is to provide a kind of measurement method of large span template arch camber, can be used to quickly to detect greatly across
The whether accurate arch camber of plank sheathing is spent, it is convenient to operate.
The present invention is implemented as follows:
A kind of measurement method of large span template arch camber, comprising the following steps:
Step 1: symmetrically installing locating rod in the upper surface of premeasuring template；
Step 2: being drawn between two locating rods and set a horizontal elongated line, elongated line is higher than premeasuring template, elongated
The end of line and the vertical range of premeasuring template upper surface are set as h1；
Step 3: the vertical range at the midpoint and premeasuring template upper surface that measure elongated line is set as h2；
Step 4: calculating springing height S, the calculation formula of springing height S is as follows: S=h1-h2；
Step 5: judging whether arch camber is accurate, if springing height S is equal with default springing height, arch camber is accurate, if rising
Pitch of arch S and default springing height are unequal, then arch camber is inaccurate, is adjusted to arch camber.
Locating rod described in two is vertically arranged in the both ends of premeasuring template.
The length of the locating rod is greater than springing height.
Compared with prior art, the present invention having the following beneficial effects:
Springing height value can be accurately calculated by height on both sides and the difference of intermediate altitude in the present invention, thus quickly
The whether accurate arch camber of large span plank sheathing is detected, convenient for the adjustment to arch camber, measurement operation is convenient, and calculation amount is few and simple, no
Influence the construction period；Locating rod of the invention and usual coil holder is set and convenient disassembly, it is at low cost.
Detailed description of the invention
Fig. 1 is the schematic diagram of the measurement method of large span template arch camber of the present invention.
In figure, 1 locating rod, 2 elongated lines, 3 premeasuring templates.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
Refer to attached drawing 1, a kind of measurement method of large span template arch camber, comprising the following steps:
Step 1: symmetrically installing locating rod 1 in the upper surface of premeasuring template 3.Locating rod 1 described in two is vertically arranged
At the both ends of premeasuring template 3, and the length of the locating rod 1 is greater than springing height.
Step 2: it is drawn between two locating rods 1 and sets a horizontal elongated line 2, elongated line 2 is higher than premeasuring template 3,
The end of elongated line 2 and the vertical range of 3 upper surface of premeasuring template are set as h1.The both ends of elongated line 2 and two locating rods 1
Tie point is located at sustained height, and elongated line 2 is made to be able to maintain horizontal position.
Step 3: the vertical range at the midpoint and 3 upper surface of premeasuring template that measure elongated line 2 is set as h2.
Step 4: calculating springing height S, the calculation formula of springing height S is as follows: S=h1-h2.
Step 5: judging whether arch camber is accurate, if springing height S is equal with default springing height, arch camber is accurate, if rising
Pitch of arch S and default springing height are unequal, then arch camber is inaccurate, is adjusted to arch camber.
The present invention need to only measure the end of elongated line 2 and the vertical range of 3 upper surface of premeasuring template when measuring operation
The vertical range h2 at the midpoint and 3 upper surface of premeasuring template of h1 and the elongated line 2 of measurement, calculating can be counted by h1-h2
Calculation obtains actual springing height and compares with preset springing height, and calculating is convenient, simple, accurate, not easy to make mistakes.
The above is merely preferred embodiments of the present invention, it is not intended to limit the protection scope of invention, it is therefore, all at this
Any modification, equivalent replacement, improvement and so within the spirit and principle of invention, should be included in protection scope of the present invention
Within.
