Problems solved by technology

[0003] During the installation of the tower-mast structure, it is required that the vertical columns are not only perpendicular to the ground, but also that the top surfaces of multiple columns must be at the same level. At present, the main construction technology uses a total station or establishes a base station, and uses GPS for construction survey; Station instrument measurement technology is limited by height and is not suitable for super high vertical structures; GPS measurement technology can solve the construction problems of vertical structures, but when the weather in the construction area is bad and the temperature difference between day and night changes greatly, it will have a great impact on precision instruments , resulting in a large measurement error

Embodiment 1

[0040] The measurement platform 1 provided in this embodiment includes: a platform body and a positioning hole 6 provided on the platform body.

[0041] Such as figure 1 As shown, the main body of the platform is a regular polygon structure, including: positioning rod 2, auxiliary connecting rod 3, panel 4 and receiving target 5; the positioning rod 2 has four, all adopt channel steel or H-shaped steel, and the two positioning rods The rods 2 are horizontally spaced and arranged in parallel, and the remaining two positioning rods 2 are vertically spaced and arranged in parallel, and the horizontally arranged positioning rods 2 are vertically connected with the vertically arranged positioning rods 2 to form a mesh support frame The auxiliary connecting rods 3 have a plurality of them, which are sequentially connected between the support frames to form a regular octagonal frame, and the center of the regular octagonal frame coincides with the center of the mesh support frame; th...

Embodiment 2

[0046] Such as figure 2 As shown, the tower mast structure in this embodiment is a regular octagonal structure, including eight vertical columns, each of which is provided with a plurality of mounting holes on the top and bottom surfaces of the columns, and each of the mounting holes surrounds The axes of the columns are evenly distributed.

[0047] Utilize the measuring platform 1 that provides in the embodiment one to measure the column of tower mast structure, comprise the following steps:

[0048] Step 1: If figure 2 As shown, three of the columns are divided into the first group, centered on the origin of the construction coordinates, vertically set up respectively and the bottom surface of the first group of columns is temporarily fixed with bolts; wherein, each of the first group of columns Columns are not adjacent to each other.

[0049] Step 2: If image 3 , Figure 4 As shown, correct the position of the first set of uprights: the measurement platform 1 is fixed...

Abstract

The invention provides a measurement and construction method for a tower-mast structure, belonging to the technical field of steel structure construction. The measurement platform comprises: a platform main body with a receiving target in the center; Circumferentially up. The measuring platform of the present invention adjusts the center position of the platform main body by means of the receiving target and the laser plumb instrument, that is, the position coordinates of each positioning hole are determined, and the positioning hole is positioned and connected to the column of the tower-mast structure, so that the center column of the tower-mast structure is connected to the column of the tower-mast structure. The ground is vertical, and each column is at the same level; the measuring platform itself will not be affected by weather, height, etc.

Description

technical field [0001] The invention relates to the technical field of steel structure construction, in particular to a measurement and construction method of a mast structure. Background technique [0002] The tower-mast structure is a vertical polygonal structure built by multiple hoistway columns. It has a large height and a relatively small cross-section. It is a commonly used structure for TV transmission towers, signal towers, and chemical towers. [0003] During the installation of the tower-mast structure, it is required that the vertical columns are not only perpendicular to the ground, but also that the top surfaces of multiple columns must be at the same level. At present, the main construction technology uses a total station or establishes a base station, and uses GPS for construction survey; Station instrument measurement technology is limited by height and is not suitable for super high vertical structures; GPS measurement technology can solve the construction ...
