Description

A cast-in-place box girder formwork diagonal bracing device

technical field

The utility model relates to the field of cast-in-place box girder formwork construction and provides a cast-in-place box girder formwork diagonal bracing device.

Background technique

The traditional cast-in-place box girder formwork system is supported by steel trusses, and the web formwork is set in the form of tie rods. It consumes a lot of steel, and the cost of processing, transportation, installation and dismantling is high, and the turnover rate is low; both installation and dismantling require large-scale hoisting equipment to cooperate with the operation, which is extremely inconvenient to install and disassemble; When the stress position conflicts, it is necessary to change the position of the tie rods at any time, resulting in low turnover rate of the formwork and poor appearance of the concrete. After the formwork is removed, the tie rod holes need to be repaired.

Utility model content

The purpose of the utility model is to provide a cast-in-place box girder formwork diagonal bracing device.

The purpose of this utility model can be realized through the following technical solutions:

A cast-in-place box girder formwork diagonal bracing device, including a main back flute, there is a gap between the main back flute and the supporting section, the gap is filled with square timber, and the main back flute is an inclined "[" type bracket, Its interior is supported by three sections of diagonal braces. The three sections of diagonal braces are composed of telescopic diagonal braces and main diagonal braces. The telescopic diagonal braces are installed at both ends of the main diagonal braces. The vertical section is provided with a vertical support seat.

The three-section diagonal brace and the main back flute are connected by bolts.

There are multiple three-section braces with different inclination angles supported in the main back flute.

Beneficial effects of the utility model: the utility model has a simple structure, and solves the problem that the traditional cast-in-place box girder formwork system adopts steel truss support, and the web formwork is provided with tie rods, which consumes a large amount of steel materials, and the cost of processing, transportation, installation and disassembly Both are relatively large, and the disadvantage of low turnover utilization rate saves materials, reduces processing, transportation and installation and disassembly costs, and improves the turnover utilization rate of the support system; improves the turnover utilization rate of formwork and improves the appearance quality of concrete; the weight of the components is small, and no large-scale hoisting is required Equipped with equipment, the installation and disassembly process is simple, easy to operate, safe and reliable.

Description of drawings

Fig. 1 is the structural representation of the utility model.

detailed description

The embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, but the utility model can be implemented in various ways defined and covered by the claims.

As shown in Figure 1, a cast-in-place box girder formwork diagonal bracing device includes a main back flute 1, there is a gap between the main back flute 1 and the supporting section 2, and square timber 8 is filled in the gap, and the main back flute 1 The corrugated 1 is an inclined "["-shaped bracket, and its interior is supported by three-section diagonal braces 5. The three-section diagonal braces 5 are composed of telescopic diagonal braces 3 and main diagonal braces 4. The telescopic diagonal braces 3 are installed The two ends of the main diagonal brace 4 are telescopic, and the vertical section of the main back flute 1 is provided with a vertical support seat 7, and the three sections of the diagonal brace 5 and the main back flute 1 are connected by bolts (6). There are multiple segment braces 5 with different inclination angles supported in the main back flute 1 .

During use, the main diagonal brace 4 (the outer casing of the diagonal brace) with the internal thread is assembled with the telescopic diagonal brace 3 (the diagonal brace adjusting screw), and the length of the diagonal brace system can be adjusted by the main diagonal brace 4 . During the construction of the cast-in-place box girder formwork, the two ends of the diagonal brace system and the main back of the box girder formwork are first connected together by bolts, and then the length of the diagonal brace is adjusted according to the size of the vertical formwork of the box girder and the main diagonal brace 4, and then the formwork system is installed.

The above content is only an example and description of the structure of the utility model. Those skilled in the art make various modifications or supplements to the described specific embodiments or replace them in similar ways, as long as they do not deviate from the utility model. Structures or beyond the scope defined in the claims shall belong to the protection scope of the present utility model.
