Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a crane beam leveling layer formwork and elevation control device. Background Art

[0002] The concrete prefabricated crane beam is installed on the concrete bracket. According to the specification requirements, after the crane beam is installed, the top surface is poured with C30 concrete to form a 30~50mm leveling layer. In order to ensure the accuracy of the track installation and the later driving, there are high requirements for the 400mm width range of the bolts on the top surface of the leveling layer, the height difference of the top surface of each bolt within any 6-meter length and along the entire length of the workshop. At the same time, there are also high requirements for the leveling layer elevation under the two tracks under the same driving. The one-way track length of the workshop is about 240 meters, with a total of 60 tracks, and the elevation control is extremely difficult. On the other hand, due to certain deviations in the elevation control of the bracket during concrete pouring, installation of embedded parts, and installation of the crane beam, the thickness of the leveling layer varies greatly, which greatly increases the difficulty of controlling the leveling layer elevation.

[0003] After the installation of the crane beam, the height reaches more than nine meters, with both sides facing the air and one side completely facing the air. It is difficult to support and reinforce the traditional wooden formwork, and the molding quality is difficult to guarantee. At the same time, the labor cost is high. Since the construction of this part is all done at high altitudes, the operation cycle becomes longer, which will also increase the safety risk. The traditional wooden formwork support method is not conducive to construction safety management, material and labor cost management. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to provide a crane beam leveling layer formwork and elevation control device, which can quickly meet the construction requirements of the crane beam leveling layer without multiple elevation measurements and can ensure that the molds are all at a horizontal elevation.

[0005] The present invention is achieved through the following technical solutions:

[0006] A crane beam leveling layer formwork and elevation control device, comprising a concrete column and a crane beam arranged on a concrete column corbel (the above all belong to the prior art); a crane beam leveling layer formwork and elevation control device also includes a leveling support and a side form; the aluminum angle steel leveling support is arranged on both sides of the concrete column and is connected and embraced on the concrete column by a connecting rod. After installation and fixation, it should be ensured that the leveling support of this section is at the same elevation, and the bottom elevation is the leveling layer control elevation, which is the main elevation control device of the entire device, that is, the elevation of other sections is the same as this The elevation of the sections is consistent; the leveling support is provided with strip holes. Due to the difference in the spacing between the crane beam and the column, the support is provided with strip holes to ensure the position of the support and the side form; the side form is arranged on both sides of the upper end of the crane beam, and is fixed to the bottom of the front end of the leveling support by fixing parts; the fixing part is made of angle steel or flat steel to form a "Z" shape, with a bending angle of 90°, and the upper part is connected to the leveling support, and the lower horizontal section plays the main support to the side form, while ensuring that the side form and the leveling support remain parallel, and also serves as a side form elevation control device.

[0007] Beneficial effects of the present invention:

[0008] The invention is easy to manufacture and use, and can simplify the construction time of the leveling layer. The construction process of formwork and elevation control only needs to measure the top elevation of the highest point of the leveling layer. After installation as required using the parallelogram principle, the elevations of the remaining parts are the same as the control elevation. At the same time, after the device is installed, the elevation control is not required during the construction of the leveling layer, which reduces the time of high-altitude operations, can quickly and effectively meet the construction requirements of the leveling layer, avoid labor waste, and ensure the molding quality of the leveling layer.

It should be noted that the terms "include", "comprise" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0017] like Figure 1-Figure 3 The shown device is a crane beam leveling layer formwork and elevation control device, comprising a concrete column 5 and a crane beam 6 arranged on the concrete column 5 (all of the above belong to the prior art); a crane beam leveling layer formwork and elevation control device comprises a leveling support 1 and a side form 3; the leveling support 1 is arranged on both sides of the concrete column 5, and is connected and embraced on the concrete column 5 through a connecting rod 4; the side form 3 is arranged on both sides of the upper end of the crane beam 6, and is fixed to the lower front end of the leveling support 1 through a fixing member 2; the fixing member 2 is made of angle steel or flat steel into a "Z" shape, and the bending angle is 90°, to ensure that the side form 3 fixed by the fixing member 2 is parallel to the leveling support 1.

[0018] Furthermore, in order to have better strength, the leveling support member 1 is an angle steel.

[0019] Furthermore, in order to ensure that the overall weight is reduced and transportation difficulties are reduced, the leveling support member 1 is made of aluminum.

[0020] Furthermore, in order to facilitate the adjustment of the position of the side mold 3 , strip holes are provided on the leveling support member 1 .

[0021] The operating steps of the present invention are:

[0022] S1. Use instruments such as levels and infrared rays to measure and lay out, determine the highest elevation of the coaxial crane beam 6, and determine the top elevation of the leveling layer of the axis accordingly based on the minimum thickness of the leveling layer of 3cm.

[0023] S2. According to the above steps, determine the top elevation of the leveling layer of the other axle of the traveling vehicle, and take the highest value of the leveling layer elevation of the axis lines on both sides of the traveling vehicle as the top elevation of the leveling layer of the crane beam 6 of this span.

[0024] S3 According to the above measurement results, determine the horizontal elevation of the highest leveling support member 1. The bottom elevation is the control elevation of the leveling layer of the axis. Use the connecting rod 4 to form a column-holding effect on the leveling support member 1 and fix it on the cast-in-place structural column 5. When fixing, ensure that the leveling support member 1 is in a horizontal state.

[0025] S4. Connect the side formwork fixing part 2 with the leveling support part 1, put in the side formwork 3, adjust the position of the side formwork fixing part 2, make the upper part of the side formwork 3 close to the leveling support part 1, the side facade close to the crane beam 6, and the lower part close to the side formwork fixing part 2, and tighten the bolts of the side formwork fixing part 2 to make the side formwork 3 parallel to the leveling support part 1. The elevation of the side formwork 3 is the elevation of the entire axis line, and there is no need to re-elevate the elevation for subsequent formwork installation.

[0026] S5 To prevent leakage of concrete during pouring, tape is used to seal the tiny gaps caused by the unevenness of the crane beam.

[0027] S6. After inspection and correction, pour concrete, and the top surface of the concrete pouring should be flush with the top surface of the side form 3.

[0028] S7. After the concrete pouring is completed, the surface is smoothed by using an iron trowel to level the top surface of the side form.

[0029] The protection scope of the present invention is not limited to the technical solutions disclosed in the specific implementation methods. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
