Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The control rib device comprises a control plate 1, wherein two ends of the control plate 1 are respectively provided with a tenon 5 and a groove 6, and adjacent control rib devices are spliced together through the tenon 5 and the groove 6. Be equipped with a plurality of arc control grooves 2 on the preceding terminal surface of control panel 1, arc control groove 2 is used for blocking vertical plane reinforcing bar 9, therefore the interval between the arc control groove 2 is the same with the interval between the vertical plane reinforcing bar 9 of design. Preferably, the diameter of the arc control groove 2 is 2-6mm larger than that of the vertical steel bar 9. The control panel 1 is used for being clamped between the vertical surface reinforcing steel bars 9 and the formworks 3, so that the width of the control panel 1 is equal to the distance between the vertical surface reinforcing steel bars 9 and the formworks 3.
The control panel 1 is connected with a clamping groove 7 and a control rib backrest 8 in sequence backwards, and the clamping groove 7 and the control rib backrest 8 are rectangular. The upper surfaces of the control panel 1, the clamping groove 7 and the control rib backrest 8 are on the same horizontal plane, and the connection among the control panel 1, the clamping groove 7 and the control rib backrest 8 can be integrally formed, can also be glued together, or can be fixedly connected together through bolts and the like, but not limited to this.
The notch of the clamping groove 7 is downward, and the notch of the clamping groove 7 is used for clamping the template 3, so that the width of the notch of the preferred clamping groove 7 is 0.3-0.5mm larger than the width of the template 3. Considering the straightness of the upper plane of the formwork 3 in the actual construction process, preferably, when the length of the rib control device is greater than 2m, the groove height of the clamping groove 7 is preferably 1-2cm, that is, the groove depth of the clamping groove 7 is preferably 1-2 cm; when the control rib device of the present invention is less than or equal to 2m, the groove depth of the locking groove 7 is less than 1 cm.
The width of the control rib backrest 8 is equal to the distance between the template 3 and the steel pipe scaffold 12, namely the width of the control rib backrest 8 is equal to the width of the reinforcing square timber 11 between the original template 3 and the steel pipe scaffold 12, so that by using the device, the reinforcing square timber 11 does not need to be added above the template 3, steps are saved, and the efficiency is improved. Preferably, the control rib backrest 8 extends downwards 3-5cm from the bottom end of the clamping groove 7, namely, the control rib backrest 8 is 3-5cm longer than the clamping groove 7, and if the control rib backrest is larger than the clamping groove 7, the control rib backrest is not easy to mount and fix in the actual operation process.
And a plurality of horizontal control holes 4 are also formed in the whole control rib device, and the horizontal control holes 4 penetrate through the whole control rib device and are horizontal holes in the width direction of the control rib device. The horizontal control hole 4 is used for penetrating through a split bolt 10 to fix the control rib devices which are opposite on two sides together.
The use of the device of the invention is briefly described below, the clamping grooves 7 of the control rib device of the invention are clamped on the formworks 3, meanwhile, the vertical steel bars 9 are clamped into the arc-shaped control grooves 2 in the control panel 1 one by one, at the moment, the control panel 1 of the device is clamped between the vertical steel bars 9 and the formworks 3, the formworks 3 are clamped by the clamping grooves 7, the control rib backrest 8 is clamped between the formworks 3 and the steel pipe scaffolds 12, the reinforced square timber 11 is originally clamped between the formworks 3 and the steel pipe scaffolds 12, and the control rib backrest 8 replaces the reinforced square timber 11 at the top of the outer side of the formworks 3, so the process of fixing the reinforced square timber 11 at the top of the outer side of the formworks 3 is omitted. The adjacent control rib devices are spliced together through the tenon 5 and the groove 6, after the control rib devices on the two sides are installed, the control rib devices on the two sides are fixedly connected together through the split bolts 10 by penetrating the split bolts 10 through the horizontal control holes 4 corresponding to the control rib devices on the two sides, then concrete pouring is carried out, the formwork stripping strength is met after the concrete pouring, and the control rib devices can be recycled after being taken out. After the device is used for pouring concrete, the concrete on the upper part can be in a convex shape, the transverse cold joint extension line and the bleeding effect of the joint part are increased, and the secondary pouring quality of the concrete joint part is improved.
