Description

A reinforced concrete beam and slab post-cast belt temporary support system

technical field

The utility model relates to a temporary support system in a construction project, in particular to a temporary support system with a post-casting belt of reinforced concrete beams and slabs, which belongs to the technical field of engineering construction.

Background technique

In order to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or uneven settlement, the post-cast belt is a temporary space left in the corresponding positions of the foundation floor, wall and beam according to the requirements of the design or construction specifications. Construction joints. The post-casting belt will cut apart the original continuous structure, so that some beam-slab structures become cantilevered, and the stress conditions have been greatly changed. In order to ensure the force of the reinforced concrete beams and slabs, a temporary support system is usually added at the post-cast belt.

The traditional post-pouring zone temporary support has the following methods: 1. The post-pouring zone support and the rest of the area support form an integral system. After the overall support is removed, the support frame body at the post-pouring zone is supported according to the template support scheme. 2. The support system at the post-casting belt is separated from the overall support system to form an independent support system, and the support system at the post-casting belt is retained when the mold is removed. 3. Pouring reinforced concrete columns under the beams next to the post-casting belt for temporary support. 4. The steel lattice columns are arranged at the corresponding positions on both sides of the post-casting belt. The first method will lead to a large number of chaotic stacking of on-site materials, occupying the site, and the secondary roofing material consumption is large and the cost is high, and the secondary roofing will easily lead to the cracking of the main structure, which has a great potential safety hazard. The second method requires a lot of turnover materials and labor, which leads to higher costs, and is not conducive to the surrounding traffic organization because the support is not removed. The third method not only requires pouring concrete columns, but also requires more time, materials and labor, and the dismantling process after use is more complicated. At the same time, a large amount of construction waste is generated, resulting in waste of construction materials. Although the fourth method solves many disadvantages of the previous methods, the cost of the steel lattice column is relatively high, and its heavy weight makes the transportation, placement and dismantling processes more complicated.

Utility model content

The technical problem to be solved by the utility model is to provide a post-casting belt temporary support system for reinforced concrete beams and slabs, which has a simple structure and is easy to construct.

In order to solve the above problems, the technical scheme adopted by the present utility model is as follows:

A post-casting belt temporary support system for reinforced concrete beams and slabs comprises a post-casting belt and beam bodies located on both sides of the post-casting belt,

The lower part of the beam body supports a plurality of lattice columns that are overlapped by socket-type disc buckle-type steel pipe supports, and the lattice columns are evenly spaced along the length direction of the beam body.

Further, the lattice column includes the socket-type disk buckle vertical rods located at the four corners, the first horizontal tie rod, the second horizontal tie rod and The inclined rod is provided with a top bracket and a bottom bracket on the top and bottom ends of the socket-type disc buckle vertical rod, respectively.

Further, the length of the first horizontal tie rod is 600 mm, the width of the second horizontal tie rod is 300 mm, and the length of the inclined rod is 1000 mm.

Compared with the prior art, the beneficial effects of the present utility model are:

1. The utility model utilizes the lattice column lapped by the socket-type disc buckle-type steel pipe bracket as the temporary support system, and the turnover material used in the project can be used without additional production, which saves the transportation link, facilitates the construction and dismantling, and greatly reduces the cost of transportation. construction costs.

2. After the concrete on both sides of the post-cast belt reaches the formwork strength, the overall formwork support system can be removed, leaving a temporary support lattice column system, which can save a lot of turnover materials and labor.

3. The construction of the utility model is simple and convenient, and all the work can be completed by using the support and erection personnel.

4. After the temporary support system of the present invention is dismantled, no construction waste will be produced, which is green and environmentally friendly.

5. Maintaining a certain distance between lattice columns will not affect the traffic of surrounding construction, and provide space for construction activities.
