Embodiment

[0076] Such as figure 1 The procedure shown is used to verify the removal condition of the support frame.

[0077] (1) if figure 2 and image 3 The axial force monitoring system of the ultra-thick floor support frame of the present invention is installed as shown.

[0078] The formwork used for pouring the super-thick floor slab includes a side formwork and a bottom formwork; the side formwork and the bottom formwork form a space for pouring floor concrete. A wooden secondary beam is installed under the bottom formwork, and a 10# I-beam main beam is installed under the wooden secondary beam. Adjustable jacking brackets are installed on top of the 5 support frames below the main beam and in the center of the entire support frame area. The jack is tightly or loosely installed under the adjustable jack; at the same time, the jack is connected to the axial force sensing line, and the axial force sensing line is connected to the data acquisition instrument set outside the supp...

Abstract

The invention relates to an axial force monitoring system of a super-thick floor support frame and a verification method of a dismounting condition of the axial force monitoring system. Specifically,the axial force monitoring system comprises a super-thick floor supporting frame (5) and an axial force monitoring device. The axial force monitoring device is used for monitoring the axial force of the super-thick floor supporting frame. And the axial force monitoring device comprises an adjustable jacking (6), a jack (7), an axial force sensing line (8) and a data acquisition instrument (9). According to the verification method for the dismounting condition of the super-thick floor supporting frame, the axial force monitoring device is installed at the top of the super-thick floor supportingframe, whether the supporting frame bears the pressure of upper-layer floor concrete or not can be accurately judged, so that whether the supporting frame can be dismounted or not can be determined in time, and the cost waste is reduced.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to an axial force monitoring system of an ultra-thick floor support frame and a verification method for demolition conditions. Background technique [0002] During the construction of ultra-thick concrete slabs, due to the volume and self-heaviness of the concrete, the bearing capacity of the concrete formwork support frame is required to be large. In order to meet the requirements of bearing capacity, there are usually two methods. One is to increase the bearing capacity of the frame body by adjusting the spacing of the vertical rods of the frame body and other factors; the other is to pour the super-thick floor slabs in layers. The lower floor is used as a formwork, and the support frame bears the load of the upper floor concrete together, and forms a whole together after the upper floor concrete is poured. When the super-thick concrete floor is poured in layers, ...
