Benefits of technology

"The present invention provides an erection unit and method for a building floor slab that can take off the floor slab mould and install the next lower layer after the floor slab is solidified to a certain level. This improves the quality of the floor slab and increases the installation speed. The erection unit includes a load-bearing member for lifting the floor slab and a traction member for pulling or supporting the floor slab. The method involves installing the floor slab mould and reinforced bars, connecting the load-bearing member to the floor slab, placing the floor slab on a height, then pouring concrete, dismantling the floor slab mould and installing the next lower layer after the floor slab is solidified to a certain level, and taking off the traction member after the floor has solidified to a strength enough to support its deadweight. This invention simplifies the installation and transportation of the floor slab mould."

Problems solved by technology

However, this erection method still has two disadvantages which are described as follows: 1) it has to wait for a certain period of time before the floor slab hardens, then the next upper floor slab can be installed.
Furthermore, it is time-consuming since the support frame and the floor slab mould should be assembled and dismantled repeatedly after each floor is completed.
2) It will have a bad effect on the structural strength of the floor slab since the lower floor slab has to bear the weight of the plural upper floor slabs, the support frame and the floor slab mould when multiple floor slabs are installed synchronously, which will likely lead deformation of the floor slab, as shown in FIG. 1.
However, this erection method still has to wait a certain period of time until the floor slab becomes hard enough to support its deadweight, then the floor slab mould can be taken away.

second embodiment

[0038] Referring to FIGS. 8, 9 and 10, which show an erection unit in accordance with the present invention, the traction members 2 in this embodiment are hook-like tension rods. After installation of the floor slab mould 4 and the steel bar, an end of each of the hook-shaped tension rods 2 is inserted in the floor slab 3 and folded to into an angle, and another end of each of the tension rods 2 is folded into a hook and connected to the steel bar 9′ on the wall 9. The tension rod 2 is obliquely arranged.

third embodiment

[0039] Referring to FIGS. 11, 12 and 13, which show an erection unit in accordance with the present invention, wherein a plate 7 is soldered with a connecting rod 14 to create a “T”-shaped mounting member that is to be inserted in the wall 9. A lower end of the connecting rod 14 is formed with threads and protrudes out of the wall 9, and alike, the connection between the traction member 6 and the floor slab 3 is also achieved through the “T”-shaped mounting member formed by the plate 7 and the connecting rod 14. The traction member 6 can be in the form of a sleeve 11 formed with threads.

[0040] The traction member shown in FIGS. 11-13 is a tension rod 2, both ends of the tension rod 2 are connected to the floor slab 3 and the wall 9, respectively, via the plate 7. The plate 7 is threadedly connected to the tension rod 2.

fourth embodiment

[0041] Referring to FIGS. 14-16, which show an erection unit in accordance with the present invention, both ends of the tension rod 2 in this embodiment are folded into a hook and connected to the steel bars 3′ of the floor slab 3 and to the steel bars 9′ on the wall 9, respectively. The tension rod 2 is threadedly connected to the sleeve 11, so that the tension rod 2 can be tensioned or released by rotating the sleeve 11 in different directions.

Abstract

An erection unit for a building floor slab is disclosed, which includes a load-bearing member for lifting the floor slab. Said load-bearing member is higher than a plane where the floor slab lies and fixed in a wall and connected with the floor slab by the aid of a traction member. A method for erecting the floor slab with said erection unit is disclosed, which includes the following processes: installing the floor slab mould; connecting the upper end of the traction member to the load-bearing member above the floor slab; placing the lower end of the traction member on the height where the floor slab is located; then pouring concrete; dismantling the mould and installing the next lower layer after the floor slab has hardened; taking off the traction member after the floor has solidified to a strength enough to support its deadweight.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to an erection unit for a building floor slab and the erection method thereof, and more particularly to an erection unit for multiple floor slabs and the erection method thereof. [0003] 2. Description of the Prior Arts [0004] The floor slab is used to vertically divide the space of a building into plural floors according to customer's requirements. At present, the floor slab of most buildings is made of concrete, as shown in FIG. 1, and the erection method is to install the next upper floor slab after the load-bearing structure (such as concrete structure) for each floor or the load-bearing structure for the whole building has been completed. After the concrete of the lower floor is poured, it needs to wait for a certain period of time until the concrete has hardened enough to bear a certain weight. And then support frame can be installed on this floor slab so as to carry out another installat...
