Combined type channel steel support template rod system and construction method thereof

Abstract

The invention relates to a strengthening part for a highway engineering side ditch, a jet stream trough, a water-power engineering cable trench and a building engineering beam template and a construction technical method thereof, and particularly relates to a combined type channel steel support template rod system and a construction method thereof. The combined type channel steel support template rod system is characterized by comprising an upper cross beam, vertical columns and inclined support rods, wherein the upper cross beam and the two vertical columns are connected through fastening pieces to form a template fixing groove; and one ends of the inclined support rods positioned on two sides of the template fixing groove are connected with the upper cross beam through the fastening pieces, the other ends of the inclined support rods are connected with the vertical columns, and the lengths of the inclined support rods are adjustable. The strengthening part disclosed by the invention is simple in structure and easy to operate in the field, can be adjusted according to different sizes of construction structures, is saved in material by being recyclable and free of influencing the beauty of the structures, can be used for improving the construction efficiency and quality, meets the requirements for demand of environmental friendliness and green construction and is wide in practicability.

[0002] At present, when pouring small concrete walls or ditches with a height of less than 1 meter and a thickness of less than 0.6 meters at construction sites in various industries such as highway engineering, municipal engineering, hydropower engineering, and construction engineering, if figure 1 , 2 The side ditch pouring is shown, and the bottom plate 61 is poured first, and then the mold groove on the pouring side is built on site using a simple formwork. The fixing of the formwork 7: usually the inside is fixed by the supporting steel bar 94 at the bottom, and the outside is made of wooden bars. 90. Vertical rods 91 and square wooden diagonal braces 93 are used as the supporting framework, combined with the reinforcement method of wall-through bolts 92. This mold groove reinforcement system processed on-site is highly random and does not depend on the experience and responsibility of the actual operators. The heart is closely related, the reinforcement process is complicated and takes a long time

Since the middle part needs to be reinforced with wall-through bolts, it is necessary to drill holes in the formwork, and the holes are prone to grout leakage during pouring. In order to reduce costs, the wall-through bolts should be recycled and reused. The hard PVC pipe 95 is used to isolate the concrete, and the wall bolts are recovered when the formwork is removed, so that there will be bolt holes on the surface of the side wall of the side ditch, which will affect the aesthetics

In order to facilitate concrete pouring, the opening above the formwork is in an open state, and the formwork at the upper opening is easily deformed, resulting in uneven construction surface of the ditch wall

If you want to increase the cross bar, you need to fix the cross bar on the formwork with steel nails, which will easily cause damage when removed, which will affect the reuse of the formwork and shorten the service life of the formwork
