Supporting device

Abstract

The invention provides a supporting device, which includes a bearing unit, several jacking units and support rods, the bearing unit includes a main frame, a number of first keels and a number of second keels, and the main frame includes two parallel first frames bar and two parallel second frame bars, the two ends of the second frame bar are vertically connected to the first frame bar respectively, the first keel is located between the two first frame bars, and the first keel The two ends of the second keel are respectively vertically connected to the second frame bar, the second keel is located between the two second frame bars, the two ends of the second keel are vertically connected to the first frame bar, and the second keel is vertically connected to the first frame bar. A keel intersects with a second keel and is fixed to each other at the intersection; the jacking unit is fixed on the first keel and / or the second keel; and the supporting rod is pressed against the jacking unit. Compared with the related art, the invention has the beneficial effects of fewer supporting parts, lower cost, high assembly and disassembly efficiency, good structural stability and high strength.

Description

【Technical field】 [0001] The invention relates to the technical field of construction, in particular to a supporting device. 【Background technique】 [0002] Prefabricated concrete not only has the advantages of factory production and standardization in construction, but also has the advantages of fast construction efficiency, low cost, and environmental protection, so it is widely used in the construction field. However, the support system required for prefabricated concrete in the process of floor slab construction is relatively complicated. For example, there are many supporting parts, including supporting rods, horizontal rods, inclined rods, etc., and the connecting parts used for connection also increase accordingly; at the same time, the arrangement density of supporting parts is high, resulting in reduced working space, which is not conducive to disassembly; The wooden formwork used to carry the floor prefabricated parts in the support system is fixed to several supp...

Problems solved by technology

However, the support system required for prefabricated concrete in the process of floor slab construction is relatively complicated.

For example, there are many supporting parts, including supporting rods, horizontal rods, inclined rods, etc., and the connecting parts used for connection also increase accordingly; at the same time, the arrangement density of supporting parts is high, resulting in reduced working space, which is not conducive to disassembly; In the support system, the wooden formwork used to carry the prefabricated parts of the floor is fixed to several support rods through the lap joint of the middle piece. Due to the influence of installation accuracy and bearing strength, the structural stability and strength of the entire support system are weak

Therefore, the support system of the related art has the disadvantages of many supports, high cost, low disassembly efficiency, poor structural stability and low strength
