Abstract
A kind of ruggedized construction of precast slab, the precast slab being intended to overcome rigidity of the prior art uneven is during lifting, easily produce the shortcoming that crack even fractures, the ruggedized construction of a kind of precast slab is provided, including having the precast slab of hollow part, also including reinforcing steel bar, described precast slab is provided with built-in joint on the frame of hollow part, reinforce steel bar and be arranged on the hollow part of precast slab, reinforce that steel bar is detachable with joint to be connected.It is uneven that this utility model overcomes rigidity during lifting, overcomes concentrated stress, it is ensured that product quality, is suitable for when the precast slab that lifting rigidity is uneven using.
Description
Technical field
This utility model relates to building industrialization field, particularly relates to the ruggedized construction of a kind of precast slab.
Background technology
Precast slab is according to the requirement of design, it may appear that the structures such as part hollow out, causes the situation that precast concrete panel stiffness is uneven.The uneven precast slab of rigidity is during lifting, due to deadweight, at rigidity sudden change or the weak position of rigidity can produce concentrated stress, causes this position easily to produce crack in hoisting process and even fractures, it is difficult to ensure product quality.
Utility model content
This utility model overcomes the uneven precast slab of rigidity of the prior art during lifting, easily produces the shortcoming that crack even fractures, it is provided that the ruggedized construction of a kind of precast slab.
This utility model realizes goal of the invention and the technical scheme is that the ruggedized construction of a kind of precast slab, including the precast slab with hollow part, also include reinforcing steel bar, described precast slab is provided with built-in joint on the frame of hollow part, reinforce steel bar and be arranged on the hollow part of precast slab, reinforce that steel bar is detachable with joint to be connected.
Described joint is riffled tube, reinforces steel bar and is threadeded with riffled tube by bolt.
Described reinforcing steel bar is channel-section steel.
The beneficial effects of the utility model are: the hollow part at precast slab sets up reinforcing steel bar, reinforcing steel bar is made to hold together with precast slab, enhance the rigidity of hollow part, make precast concrete panel stiffness uniform, concentrated stress is overcome, it is ensured that product quality during lifting.Meanwhile, reinforce that steel bar is detachable with joint is connected, after lift, dismounting reinforcing steel bar, do not affect the structure of precast slab, the most reusable, beneficially environmental protection.
The utility model will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A direction view of Fig. 1.
In accompanying drawing, 1 for reinforce steel bar, 2 be bolt, 3 for precast slab, 3-1 be frame, 3-2 be joint.
Detailed description of the invention
As shown in drawings, the ruggedized construction of a kind of precast slab of the present embodiment, including having the precast slab 3 of hollow part, also include reinforcing steel bar 1, the reinforcing steel bar 1 of the present embodiment is channel-section steel.The position that hollow part is usually at rigidity sudden change or rigidity is weak, for improving the rigidity at this, precast slab 3 is provided with built-in joint 3-2 on the frame 3-1 of hollow part, and joint 3-2 carries out pre-buried when making precast slab 3, for being connected with reinforcing steel bar 1.Reinforce steel bar 1 and be arranged on the hollow part of precast slab 3, in order to not affect the overall structure of precast slab 3, and consider repeatable utilization, reinforce that steel bar 1 is detachable with joint 3 to be connected.The present embodiment preferred joint 3-2 is riffled tube, reinforces steel bar 1 and is provided with the through hole that bolt 2 passes, and reinforces steel bar 1 and is threadeded with riffled tube by bolt 2.
Before lifting, the two ends reinforcing steel bar 1 are separately fixed on the joint 3-2 of precast slab 3 by bolt 2.Strengthen the rigidity at the position that precast slab 3 is at hollow part i.e. rigidity sudden change or rigidity is weak by reinforcing steel bar 1 so that precast slab 3 rigidity is uniform, during lifting, overcome concentrated stress, it is ensured that product quality.After having lifted, remove and reinforce steel bar 1, do not affect the structure of precast slab 3, the most reusable, beneficially environmental protection.
Claims (3)
1. the ruggedized construction of a precast slab, including the precast slab with hollow part, it is characterized in that, also include reinforcing steel bar (1), described precast slab (3) is provided with built-in joint (3-2) on the frame (3-1) of hollow part, reinforcing steel bar (1) and be arranged on the hollow part of precast slab (3), reinforcing steel bar (1) is detachable with joint (3-2) to be connected.
The ruggedized construction of a kind of precast slab the most according to claim 1, it is characterised in that described joint (3-2) is riffled tube, is reinforced steel bar (1) and is threadeded with riffled tube by bolt (2).
3. according to the ruggedized construction of a kind of precast slab described in claim 1 or 2, it is characterised in that described reinforcing steel bar (1) is channel-section steel.
