Meanwhile, the manpower of operators is saved (the prefabricated cushion blocks do not need to be bound), concrete pouring in different periods is avoided, and the quality level of concrete beam operation is improved.
Description
Technical Field
The utility model relates to a scaling-off device, concretely relates to guarantee scaling-off device of cast-in-place concrete structure roof beam side steel bar protection layer thickness.
Background
The outer side surface of the steel bar on the side surface of the concrete structure beam needs to be poured with a protective layer with a specific thickness. The role of the steel bar protection layer mainly has two points: firstly, the anchoring of the bond coat concrete to the stressed steel bar is ensured; and the steel bars are prevented from being corroded due to contact with air. The current construction specifications have strict requirements on the thickness of the protective layer. If the thickness of the protective layer cannot be guaranteed, particularly if the reinforced concrete member is in an acidic or alkaline environment for a long time and the thickness of the protective layer cannot be guaranteed, the reinforcing steel bar can be passivated in the alkaline environment or rusted in the acidic environment, so that the quality of the reinforced concrete member is influenced. Therefore, it is very important to ensure the thickness of the steel bar protection layer by sizing in the construction quality control.
In order to ensure the thickness of the protective layer, the method in the prior art is to prefabricate a concrete strip-shaped cushion block with a specific thickness (the strength grade is the same as that of poured concrete), and when the concrete strip-shaped cushion block is used, the concrete strip-shaped cushion block is bound on a concrete beam stirrup (one binding position is bound according to the distance of 1 meter). The method has the disadvantages that the field construction amount is large, the prefabrication and the binding of the cushion blocks are troublesome, and the bound cushion blocks can fall off when colliding; the cushion blocks are easy to break, and cannot play a role in supporting and positioning after being broken; in addition, the thickness of the protective layer of the concrete can not reach the standard when the reinforcing steel bar is impacted by the concrete; the prefabricated concrete strip-shaped cushion block cannot be reused, and materials are wasted; the concrete cushion block and the cast-in-place concrete belong to casting forming in different periods, and the combination of new concrete and old concrete is difficult, so that the engineering construction quality is difficult to ensure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a but recycle's cast-in-place concrete beam side protective steel bar layer scale device is provided, the scale operation is more convenient, avoids the shaping of different phases concrete placement in order to improve construction quality to scale device can reuse, reaches material saving's purpose.
The technical scheme of the utility model as follows:
a recyclable sizing device for a steel bar protection layer on the side surface of a cast-in-place concrete beam is characterized by comprising a cross beam connected with a lifting handle, wherein two sleeves capable of sliding along the axial direction of the cross beam are mounted on the cross beam, and the two sleeves are connected with a protection layer thickness sizing rod.
Preferably, two ends of the cross beam are respectively and fixedly provided with a plug for preventing the sleeve from slipping.
Preferably, the lower end of the protective layer thickness sizing rod is a flat end.
The utility model has the positive effects that:
adopt the utility model discloses, no longer need prefabricate the cushion in advance to the control of on-the-spot concrete beam side protective layer, save material and construction cost, this device can recycle moreover. Not only the precision control of the thickness of the protective layer is ensured, but also the construction progress is accelerated. Meanwhile, the manpower of operators is saved (the cushion blocks are not required to be bound and prefabricated), the concrete pouring in different periods is avoided, and the quality level of the concrete beam operation is improved.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic view of a usage status of the embodiment of the present invention.
In the drawing, 1, a protective layer thickness sizing rod, 2, a plug, 3, a sleeve, 4, a cross beam, 5, a lifting handle, 6, a concrete beam steel reinforcement framework, 7 and a template.
Detailed Description
The invention will be further described with reference to the following examples and drawings.
Referring to fig. 1, the embodiment of the present invention includes a cross member 4 in the form of a circular tube, a lifting handle 5 is fixedly connected to the cross member 4, and the lifting handle 5 is generally T-shaped. Two sleeves 3 capable of axially sliding along the cross beam 4 are mounted on the cross beam 4, the two sleeves 3 are fixedly connected with a protective layer thickness sizing rod 1, and the thickness of the protective layer thickness sizing rod 1 is used as the sizing thickness of a concrete beam side protective layer.
And two ends of the cross beam 4 are respectively and fixedly provided with a plug 2 for preventing the sleeve 3 from slipping. When the device is collected or left unused in a warehouse, the two protective layer thickness sizing rods 1 cannot slip.
The lower end of the protective layer thickness sizing rod 1 is a flat end, so that the protective layer thickness sizing rod 1 is beneficial to being inserted and pulled out, and occupies a smaller space.
In actual manufacturing, the plug 2 is a galvanized steel pipe sealing plate with the thickness of 5mm, the sleeve 3 is a phi 40 galvanized steel pipe, and the cross beam 4 and the lifting handle 5 are phi 25 galvanized steel pipes. In a factory, a protective layer thickness sizing rod 1 is welded on a sleeve 3 and sleeved on a cross beam 4, and two sides of the cross beam 4 are blocked by plugs 2. The T-shaped lifting handle 5 is welded at the middle position of the cross beam 4.
As shown in fig. 2, at a construction site, a template 7 is supported, after a concrete beam steel reinforcement framework 6 (the concrete beam steel reinforcement framework 6 consists of a beam main reinforcement and a beam stirrup) is installed, the distance between two protective layer thickness sizing rods 1 of the device is adjusted according to the beam width, two sleeves 3 are fixed by holding, then the two protective layer thickness sizing rods 1 are inserted between the template 7 and the concrete beam steel reinforcement framework 6, a plurality of devices are used according to the distance of 1 meter, and then concrete is poured. When the concrete is poured, the concrete is sufficiently vibrated to ensure that the concrete is filled densely, and then the protective layer thickness sizing rod 1 is pulled out of the dense concrete by means of the lifting handle 5. Finally, the concrete surrounding the gap formed by pulling out the protective layer thickness gauge rod 1 is slightly vibrated by a vibrating rod, and the gap is automatically filled with the concrete because the concrete is not completely solidified. And finishing the cast-in-place operation of the concrete beam.
