Description
Technical Field
The utility model relates to a bridge construction tool's technical field especially relates to a precast beam roof cross slope controlling means.
Background
In highway and municipal bridge engineering, the simply-supported continuous beam is widely applied to bridge engineering due to strong bearing capacity, relatively low dead weight and low manufacturing cost, particularly to a bridge with the span of 20-40 m, the T beam/box beam is an important component of a bridge main body, and if wing plate cross slope control is not strict during prefabrication construction and pre-camber control is not proper during installation construction, beam surface elevation deviation and beam body linearity are poor, and the quality of the whole bridge is not over-closed. Therefore, the quality of the transverse slope and the pre-camber of the wing plate in the beam plate prefabricating process is a key point for construction control, and the quality of the transverse slope and the pre-camber seriously affects the overall quality of bridge engineering and the smooth implementation of projects.
In the process of manufacturing and constructing the precast beam, the conventional method for controlling the cross slope of the top wing plate of the beam is to adjust the heights of the wing plate templates on two sides or use a level gauge for measurement and inspection, but in practical application, the slope rate of the cross slope is adjusted by adjusting the height difference of the two side templates, after the templates are used for a period of time, the steel of the templates can deform, so that the structural size changes, and at the moment, the cross slope is adjusted through the heights of the templates, so that the error is large. And adopting a level gauge to measure and control, at least two sections need to be measured on each section of template, one section needs to measure two points, the elevations of the two points need to be recorded, and the cross slope gradient rate is checked according to the top width of the precast beam after the height difference is calculated. The method generally needs 3 persons to control the transverse slope, one person uses an instrument to measure, one person records and calculates the slope rate, and one person uses a tower ruler to set up a ruler, so that the method is relatively complicated.

Detailed Description
As shown in fig. 1 and 2, the utility model relates to a precast beam roof cross slope controlling means includes control lever 1, and control lever 1 is made for square steel, and its length is longer than the width of precast beam. Threaded hole 2 is seted up to the bottom surface that is close to 1 one end of control lever, and threaded hole 2 wears to be equipped with screw rod 3 apart from 1 tip of control lever 20cm at least in the threaded hole 2, screw rod 3 one end threaded connection in threaded hole 2, and the other end stretches out 1 bottom surface of control lever. The top surface of the control rod 1 is provided with a level ruler 4 for measuring the horizontal state of the control rod 1.
Adjusting screw 3's length of unscrewing during the use, make length of unscrewing and the same cross-section both ends of precast beam because the difference in height that the cross slope produced unanimous, then arrange screw 3 one end in on the side form board, the other end of control lever 1 is arranged in on the other side form board, level bubble like level 4 is placed in the middle, then the cross slope accords with the design requirement, if the bubble slope, then it does not accord with the design requirement to show this section department cross slope, adjustment one side control lever 1 makes the bubble placed in the middle, the interval between 1 bottom of control lever and the precast beam template this moment is exactly the distance that the calibration needs the adjustment.
Furthermore, a plurality of threaded holes 2 are formed in the control rod 1 at intervals along the length direction of the control rod, the distance from the control rod 1 to each threaded hole 2 is the length specification of the precast beam, and therefore the precast beam is suitable for precast beams of different specifications by selecting the threaded holes 2 at different positions, and the applicability is higher.
The level 4 can be placed on the top surface of the control rod 1 and can also be detachably arranged on the top surface of the control rod 1. When control lever 1 demountable installation is at 1 top surface of control lever, embedded first magnet on control lever 1, embedded second magnet with first magnet inter attraction on level bar 4 through magnet inter attraction to make level bar 4 install on control lever 1, stability is good, ann tears the convenience open.
A handle 5 is hinged on the top surface of the control rod 1, the control rod 1 is convenient to carry through the handle 5, and the control rod 1 is convenient to control when the level bubble is adjusted.
The using process is as follows:
adjusting the screwing-out length of the screw rod 3 to enable the screwing-out length to be consistent with the height difference generated by the cross slope at two ends of the same section of the precast beam, placing the screw rod 3 on a template at one side of the precast beam, placing the other end of the control rod 1 on the opposite side template, observing whether the leveling bubble of the leveling rod 4 is centered or not, and if so, indicating that the cross slope at the position meets the design requirement; if the air bubble inclines, the cross slope of the cross section at the position does not accord with the design value, at the moment, the control rod 1 is held by hands, the leveling air bubble is adjusted to be centered, the distance between the bottom of the control rod 1 and the precast beam template is observed, and the distance is the height needing to be calibrated.
The method and the device improve the control efficiency of the site cross slope, reduce the investment of site personnel, reduce the construction cost and have good economic benefit; and adjustable screw rod 3 and adjustable control lever 1 can be suitable for the precast beam of different width specifications and the precast beam of different cross slopes, have improved the suitability of device.
