Description
Technical Field
The utility model relates to a construction technical field especially relates to a be used for rectangular concrete floor to strike off rail set.
Background
Currently, flatness control is one of the key quality parameters of concrete floors. The strickling of cast-in-place concrete is a key construction step for controlling flatness, and the current common method comprises the following steps: the manual work utilizes wooden scraper blade or aluminum alloy chi to strickle off, and the control measure is comparatively extensive. The main structure of a certain project is a semi-buried water pool with the length of 400 meters, the width of 18 meters and the depth of 10.3 meters, concrete on the bottom plate of the deep water towing water pool is divided into 9 blocks and poured in stages according to expansion joints, and the concrete volume of the maximum block bottom plate is about 1392m3。
If the traditional method is adopted, after the concrete is slightly watered after about 2 hours after the concrete is tamped (before the concrete is initially set), the iron roller is used for compacting two sides longitudinally and transversely and repeatedly, the long scraping ruler is used for scraping again, then the artificial wooden crab is used for leveling, the field workload is large, the labor intensity of workers is high, the efficiency is low, the flatness of the bottom of the pool is difficult to control, and in addition, the reinforcing steel bar grids laid on the cushion layer are embedded during pouring, which also brings inconvenience to the workers.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the present embodiment provides a track set for screeding a long concrete floor, which comprises strickle tracks respectively positioned on two sides of the upper surface of a concrete cushion layer 1, wherein the strickle tracks comprise a trapezoidal pipe track 2, an elevation saddle 3 and a countersunk head screw 4, the section of the trapezoid pipe track 2 is in an equilateral trapezoid shape, the upper trapezoid bottom of the trapezoid pipe track 2 is positioned at the bottom, the lower trapezoid bottom is positioned at the top, the trapezoid pipe track 2 is provided with a countersunk screw hole from the top to the bottom, the elevation saddle 3 comprises a screw 31 and a square table 32 fixed on the screw 31 in a T shape, the top of the square platform 32 is provided with an internal thread hole, the screw 31 is fixed in the concrete cushion 1, countersunk screw 4 passes through countersunk screw hole and the fixed trapezoidal pipe track of internal thread hole 2 and elevation saddle 3, be fixed with the reinforcing bar net piece 5 that has the support between the strickle off the track of both sides.
Firstly, pouring a concrete cushion layer 1, after the concrete cushion layer is hardened, then, paying off along the edge of the ground surface, and drawing two parallel positioning lines on the concrete cushion layer 1. One side of the leveling track is installed, an elevation saddle is installed along a positioning line, the elevation saddle 3 is fixed on the concrete cushion 1 through external threads of a screw, a specified elevation is guaranteed, and the elevation saddle is fixed through a check bolt; the side die 6 is clamped and fixed on the upper part of the screw rod through a buckle; the trapezoid pipe track 2 is fixedly connected with the elevation supporting platform 3 through a countersunk head screw until the installation of the leveling track on one side is finished. Then, the mesh with the bracket is placed. The other side of the scraping rail is installed in the same way.
The workman scrapes the operation through the scraper blade along two equal altitude strickles the track and scrapes, and the original subjective method of judging concrete ground flatness of effectual solution guarantees that ground is level.
Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
