Detailed Description

The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and functions of the present invention, but the present invention is not limited thereto.

The utility model provides a pair of vertical support device of formwork on reinforcing bar net rack comprises upper cross bracing piece 3, pole setting 2, lower floor's cross bracing piece 1 and horizontal support bar 4 etc. and four extreme points of lower floor's cross bracing piece 1 fixed connection crotch that open side down respectively, as shown in fig. 1. The central connecting point of the lower cross-shaped support rod 1 is fixedly connected with the lower end of the vertical rod 2, the middle part of the vertical rod 2 is fixedly connected with the upper cross-shaped support rod 3, the upper part of the vertical rod 2 is fixedly connected with the horizontal support rod 4, and the height of the horizontal support rod 4 is higher than that of a concrete bottom plate 9 to be poured (300 mm). The radian of the hook is matched with the diameter of the steel bar, so that the hook is ensured to be hung on the steel bar. The cross support rods adopt cross rods with staggered heights or a method for increasing the depth of a hook to adjust the height difference of transverse and longitudinal steel bars in the steel bar net rack.

The first embodiment is as follows: four hooks of lower floor's cross bracing piece 1 hang respectively on bottom plate steel reinforcement net rack bottom reinforcing bar 5, and the length of upper cross bracing piece 3 is greater than 6 net sizes of bottom plate surface course reinforcing bar, and the surface course reinforcing bar 6 of bottom plate steel reinforcement net rack is placed to 3 up ends of upper cross bracing piece, and it is firm with 3 ligatures of upper cross bracing piece with the surface course reinforcing bar 6 with the iron wire. The other parts have the same structure.

Example two: four hooks of lower floor's cross bracing piece 1 hang respectively on bottom plate steel bar net rack bottom reinforcing bar 5, four extreme points of upper cross bracing piece 3 weld opening crotch up respectively, with 6 cards of bottom plate steel bar net rack's surface course reinforcing bar in the hook of upper cross bracing piece 3, as shown in fig. 2, save the ligature link, improved the efficiency of construction, reduced the cost of labor. The other parts have the same structure.

Referring to fig. 3, the vertical scaffold tubes 7 of the formwork support system are sleeved on the upper portions of the vertical rods 2, the vertical scaffold tubes 7 are clamped by the horizontal support rods 4, the vertical scaffold tubes 7 and the horizontal scaffold tubes 8 are fixedly connected and erected with fasteners to form a formwork support frame, and after the formwork support system is erected, concrete is poured on the top plate and the bottom plate at the same time. The formwork system is dismantled after the concrete of the bottom plate and the top plate is maintained simultaneously, the vertical rods 2 and the horizontal supporting rods 4 of the upper surface part of the concrete bottom plate 9 of the device are partially cut off, and the whole pouring construction period is shortened.

This device simple structure, the cost of manufacture is low, and the convenient fast speed of handling installation, the adjusting device position at will, concrete bottom plate 9's roughness precision is high, and the support effect is good.

Finally, it is noted that: the preferred embodiments of the present invention have been shown and described, and it will be understood that modifications and variations may be made by those skilled in the art without departing from the scope of the invention.
