Description

Technical Field

[0001] The invention belongs to the technical field of construction equipment, and in particular relates to a high-support formwork system interlayer top surface safety laying device and a use method thereof. Background Art

[0002] Engineering construction refers to the activities of measuring, working and inspecting to realize the design intent on the construction site in accordance with the requirements of design drawings and related documents, so as to form the final product of the engineering entity. Construction layout is an indispensable link in the process of engineering construction. Construction layout is a prior inspection of the positioning of the construction project to ensure that the construction project is carried out safely and smoothly in accordance with the requirements of planning approval, while taking into account the improvement of municipal facilities, improving environmental quality, and avoiding infringement on the interests of adjacent property rights. The "Urban and Rural Planning Law of the People's Republic of China" clarifies the relevant matters of issuing "one book and two certificates", but does not make specific provisions for the approval of the commencement and completion of construction projects. As a result, some construction units and construction units lack awareness of the importance of commencement inspection and completion acceptance, and simply regard this as a general administrative inspection. Delays in application for approval often occur. In fact, commencement inspection and completion acceptance are two indispensable administrative licensing links in planning implementation management.

[0003] Most of the existing construction layout devices are traditional: after the corresponding control line is popped out on the ground, the control line of the top surface is drawn by a plumb line, or the control line of the top surface is drawn directly based on visual observation. However, this method has the following disadvantages: 1. The layout is inaccurate and the accuracy is biased; 2. The operation is complicated and the layout efficiency is low, which cannot meet the layout requirements of engineering construction; 3. The distance between buildings is too large and tools such as mobile scaffolding are needed, which increases safety risks.

[0004] Therefore, how to improve the accuracy of engineering layout and complete the layout work safely and efficiently is a problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0005] In order to solve the above technical problems, the inventors have obtained the technical solution of the present invention through practice and summary. The control line can be positioned when the upper floor slab is not constructed, and the position of the control line can be reviewed after the construction is completed. The present invention discloses a high-support formwork system interlayer top surface safety line-laying device, including:

[0006] A base, wherein the base is provided with a supporting section, and the supporting section is provided with a connecting section which can be adjusted up and down;

The line-stretching position is controlled by emitting a linear laser, which greatly improves the accuracy of the line-releasing.

[0008] Further preferably, the plucking member includes a mounting plate arranged on the connecting seat, and a ratchet rotatably mounted on the front end of the mounting plate, wherein the ratchet is located within a circle of ink lines and is close to the upper line.

[0009] Further preferably, a spring button for controlling the rotation of the ratchet is provided on the connecting section.

[0010] Further preferably, the connecting section is provided with a hollow structure, the size of the lower end inside the tube is matched with the supporting section for connection, and a cylinder assembly for lifting is provided between the supporting section and the connecting section.

[0011] Further preferably, a limit block is provided on the support segment, and the limit block is an annular square ring fixed to the outer surface of the support segment.

[0012] Further preferably, the cylinder assembly comprises a cylinder mounted on the top of the square ring, and a telescopic rod connected to the output end of the cylinder, and a free end of the telescopic rod is connected to the bottom of the connecting section.

[0013] Further preferably, a through hole is provided on the connecting section, an adjusting bolt is provided in the through hole, and a plurality of connecting holes matching with the adjusting bolt are provided on the upper end of the supporting section.

[0014] Further preferably, a correction unit is provided on the support section, and the correction unit is a level bubble.

[0015] Further preferably, the base is arranged in a cubic structure with a hollow middle portion, and universal wheels are respectively provided at the four corners of the bottom.

Then, the adjusting bolt is pulled out to release the fixation. The connecting section is driven up by the cylinder assembly. When the top of the connecting seat contacts the top plate, the adjusting bolt is pushed into the connecting hole to fix it. Then, the correction unit is used to correct whether the structure is vertical again.
