Description
Technical Field
The utility model relates to an interim support system among the building engineering especially indicates, reinforced concrete roof beam slab post-cast strip interim support system belongs to engineering building technical field.
Background
The post-cast strip is a temporary construction joint reserved at the corresponding position of a foundation slab, a wall and a beam according to the design or construction specification requirement in order to prevent a possibly generated harmful crack of a cast-in-place reinforced concrete structure due to nonuniform self shrinkage or nonuniform settlement in the building construction. The post-cast strip can cut the original continuous structure, so that part of the beam slab structure becomes a cantilever state, and the stress working condition is greatly changed. In order to ensure the stress of the reinforced concrete beam slab, a temporary support system is usually additionally arranged at the post-cast strip.
The conventional post-cast strip temporary support has the following methods: 1. the support at the post-cast strip position and the support at the rest area form an integral system, and the support frame body at the post-cast strip position is erected according to the template support scheme after all the supports are integrally dismantled. 2. And the post-cast strip support system is separated from the integral support system to form an independent support system, and the post-cast strip support system is reserved during the form removal. 3. And pouring small reinforced concrete columns under the beam beside the post-cast strip to serve as temporary supports. 4. And the corresponding positions of the two sides of the post-cast strip are provided with the section steel lattice columns. The first method can cause a large amount of disordered field materials to be stacked, occupies a field, has large using amount of secondary back-jacking materials and high cost, and easily causes cracking of a main body structure due to secondary back jacking, thereby having great potential safety hazard. The second method requires a large amount of turnover material and labor, results in high cost, and is not favorable for surrounding traffic organization because the support is not removed. The third method not only needs to pour the concrete column, and has more time, materials and labor, but also has more complex dismantling process after the concrete column is used up, and simultaneously generates a large amount of construction waste to cause the waste of construction materials. The fourth method solves the disadvantages of the former methods, but the steel lattice column has high cost and heavy weight, which makes the transportation, installation and dismantling processes complicated.

Furthermore, the lattice column comprises socket type plate buckle vertical rods positioned at four corners, a first horizontal pull rod, a second horizontal pull rod and an inclined rod, wherein the first horizontal pull rod, the second horizontal pull rod and the inclined rod are respectively connected with adjacent socket type plate buckle vertical rods in an inclined mode along the length direction and the width direction, and the top end and the bottom end of each socket type plate buckle vertical rod are respectively provided with a top support and a bottom support.
Further, the length of the first horizontal pull rod is 600mm, the width of the second horizontal pull rod is 300mm, and the length of the inclined rod is 1000 mm.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. the utility model discloses utilize socket joint type dish to detain lapped lattice column of steel pipe support as interim support system, the turnover material that usable project used need not to make separately, has saved the transportation link, is convenient for build and demolish, has reduced construction cost by a wide margin.
2. After the concrete on the two sides of the post-cast strip reaches the form removal strength, the whole formwork support system can be removed, a temporary support lattice column system is left, and a large amount of turnover materials and labor force can be saved.
3. The utility model discloses the construction is simple and convenient, utilizes to support and sets up personnel and can accomplish all works.
4. The utility model discloses a can not produce building rubbish, green after interim braced system demolishs.
5. The lattice columns are kept at a certain distance without influencing the traffic of peripheral construction, and a construction activity space is provided.
