technical field

The invention relates to the field of concrete frame structure construction, and more particularly to the reinforcement structure of large-span high-rise high-rise scaffolding.

Background technique

At present, the cast-in-place concrete frame structure is widely used in the structure of workshops and commercial complexes. During the construction of the main body of the building, in order to ensure the safety of the construction process and the aesthetics of the entire construction site, it is necessary to set up construction and protection on the outside of the building. Scaffolding structure. Considering the safety and overall stability of the scaffolding body, the anti-overturning ability of the scaffolding body should be as large as possible. In order to meet such conditions, in traditional structures, the frame body is generally reinforced by means of connecting wall parts. However, for the large-span high-rise concrete frame structure system, due to the influence of the excessive span and storey height, it is impossible to set up the connecting wall according to the conventional method, or use additional columns or beams as the connecting point of the connecting wall, which is costly and expensive. complex. Therefore, in this case, it is particularly important to study a scaffolding protection method for long-span high-rise structures that can not only reduce the tie points of connecting wall parts but also meet the safety performance.

There are the following problems in the traditional method of connecting the wall with ordinary steel pipes: ① During the construction process, the workers are easy to remove the set connecting wall, resulting in the frame body is not firmly reinforced; ② The middle part of the construction site with a large span cannot be pressed. The wall-connecting fittings are conventionally set; ③ the setting of the wall-connecting fittings is relatively random, and the adjacent spacing is too large to meet the requirements.

Description of drawings

Figure 1 is a schematic top view of the scaffolding and buttress columns.

Detailed ways

In view of the above technical solutions, preferred embodiments are now given and described in detail with reference to the drawings.

Referring to Figure 1, the scaffolding is constructed by fasteners through scaffolding vertical rods 1, horizontal horizontal rods 2, and vertical horizontal rods 3. The scaffolding is fixedly connected with the connecting wall piece 4 through fasteners.

The buttress column 5, referring to FIG. 1, is shown by the dotted line in the figure, which is the cross-sectional range of the buttress column. The buttresses and scaffolding were erected simultaneously.

The part of the buttress column 5 is inserted between the scaffolding structures, and is fixedly connected to the scaffolding through the vertical rod 51, the horizontal rod 52 and the fastener. The vertical rods 51 and the horizontal rods 52 at the edge of the buttress column in the scaffolding are both vertical rods and horizontal rods of the scaffolding. The part of the buttress column located on the outer side of the scaffold is constructed by the vertical rod 51 and the horizontal rod 52 . The buttress column and the scaffolding have the same height and step distance. The purpose of the steps is the same so that the construction workers can walk between the scaffolding and the buttresses. When erecting the bottom layer of the buttress column, the concrete base of the buttress column needs to be poured separately on the ground, so that the bottom foundation of the buttress column is embedded in the concrete base of the buttress column, and then the vertical rod, horizontal rod and The vertical and horizontal bars of the scaffold are fixedly connected by fasteners. In the position where there is no buttress column, the connecting wall piece 4 is arranged in a conventional manner, and the overall stability of the scaffold is improved through the joint action of the connecting wall piece and the buttress column concrete base.

Design dimensions of buttress columns: the length L of the buttress columns is greater than the longitudinal spacing of the scaffolding, and the width W is not less than the horizontal spacing of the scaffolding. The longitudinal spacing of buttress columns is smaller than that of scaffolding columns, and the horizontal spacing is smaller than that of scaffolding columns; the lateral spacing of buttressing columns is a multiple of the horizontal spacing of scaffolding columns, and the longitudinal spacing is the same as that of scaffolding columns. The longitudinal spacing of the rods is multiplied. That is: the pole density of the buttress column is higher than that of the scaffold. The distance between the two adjacent vertical poles of the buttress column is determined according to the size of the scaffold and the size of the building. The distance between two adjacent buttress columns shall not be greater than the calculated span requirement between two adjacent wall pieces.

The specific erection position and section size of buttress columns can be adjusted according to the size, outline shape of the building on the construction site and the overall arrangement of the construction site, and are suitable for concrete frame structures of various shapes and sizes. The construction materials of the buttress columns are all taken from the existing materials on the construction site, and are consistent with the scaffolding materials. There is no cost for secondary processing and production, which is in line with the concept of green construction.

The reinforcement method of the present invention for reinforcing the scaffold by the buttress columns can effectively reduce the installation density of the connecting wall parts, and by setting the buttress columns, it can be well solved that in the large-span high-rise high-rise frame structure system, the connecting walls cannot be set according to the conventional density. The way of parts improves the stability and reliability of the whole frame.
