Description

[0002] Composite slabs of corrugated steel sheets and concrete refer to composite slabs composed of concrete poured on corrugated steel sheets. They can be divided into composite slabs and non-composite slabs based on whether the corrugated steel sheets work together with the concrete. Composite slabs refer to cast-in-place concrete slabs in which the corrugated steel sheets, in addition to being used as a permanent formwork for pouring concrete, also serve as tensile reinforcement at the bottom of the slab. Non-composite slabs refer to cast-in-place concrete slabs in which the corrugated steel sheets serve only as a permanent formwork for the concrete slab and do not participate in structural stress. During construction, temporary supports must be added to the cantilevered areas around the slab during concrete pouring to ensure that the slab deformation requirements are met when the concrete does not reach the design strength.

[0028] The use state of the present invention is as follows: the present invention has a reasonable and simple structure, low production cost and convenient installation. When in use, first place the mounting seat 4 on the fixed beam 1 and make the clamping seat 1 2 and the clamping seat 2 11 respectively located on both sides of the fixed beam 1. The locking mechanism 1 3 and the locking mechanism 2 10 provided here can quickly fix the mounting seat 4 on the fixed beam 1, thereby improving the convenience when in use, and also ensuring the stability and reliability of the support. When locking, first drive the driving gear 32 to rotate through the rotating head 34 and the transmission shaft 33, and the rotation of the driving gear 32 drives the screw 38 to rotate through the driven gear 35, and the rotation of the screw 38 causes the movable block 37 to drive the longitudinal block 39 to move downward, and the downward movement of the longitudinal block 39 causes the locking arm 311 to move downward on the left side through the pressing block 310, and the downward movement of the locking arm 311 causes its right side to move upward and press the fixed beam 1 through the tightening block 315, thereby achieving the purpose of fast fixing and locking.

Here, the centering gear rack mechanism composed of the rack 1 611, the connecting gear 612 and the rack 2 613 ensures that the support seat 67 can only move up and down vertically, which ensures that the template support will not be offset during adjustment, thereby improving the template support effect. In addition, several sliders 7 are provided, which can adjust the positions of several adjustable support mechanisms 6 as needed. After adjustment, tighten the tightening screws 9, and all sliders 7 can be clamped by the stop block 8, thereby ensuring reliability and stability during support.
