fig. 2 is a schematic structural view of fig. 1 after the transverse ribs and the vertical ribs are connected.
Detailed Description
The utility model discloses a unilateral is reinforcing apparatus for formwork system's embodiment:
the utility model discloses a concrete structure of reinforcing apparatus for unilateral formwork system is as shown in fig. 1 to fig. 2, including horizontal muscle 1 and perpendicular muscle 2, erect 2 welded fastening of muscle and form cruciform structure on horizontal muscle 1 and after the welding, set up the screw thread on the full length scope of horizontal muscle 1, its outside cover has butterfly buckle 3 and nut 4 in proper order, and butterfly buckle 3 can slide along the length direction of horizontal muscle 1, nut 4 and 1 threaded connection of horizontal muscle.
In this embodiment, the vertical rib 2 is fixed on the horizontal rib 1 through the middle part, that is, the part of the vertical rib 2 above the horizontal rib 1 is equal in length to the part below the horizontal rib 1. Meanwhile, the length of the transverse ribs 1 extending out of the vertical ribs 2 is greater than half of the length of the vertical ribs 2. Specifically speaking, in the cruciform structure that vertical bar 2 welded and formed on horizontal bar 1, vertical bar 2 stretched out horizontal bar 1 and the both ends head length that forms was 4cm, and horizontal bar 1 inwards stretches out vertical bar 2 and the end head length that forms is 6cm. In other embodiments, the four side arms of the cross-shaped structure formed by welding the transverse rib 1 and the vertical rib 2 can have other proportional relationships.
Use the utility model discloses principle when consolidating unilateral formwork system is as follows: firstly, a hole is formed in the template 5, the outer side of the transverse rib 1 penetrates through the template 5, and then the vertical rib 2 abuts against the inner side surface of the template 5 so as to prevent the transverse rib 1 from being separated from the outer side of the template 5; add in proper order in the template 5 outside and establish vertical fixed stupefied 4 and fore-and-aft fixed main stupefied 5, install butterfly buckle 3 and nut 4 in proper order on the horizontal muscle 1 in the outside again, thereby nut 4 drives butterfly buckle 3 and all compresses tightly fixed main stupefied 5 with fixed stupefied 4 on template 5 towards fixed main stupefied 5 motion when screwing up nut 4, accomplishes the reinforcement to unilateral formwork system. After the reinforcement is finished, concrete can be poured on the inner side of the template 5, and after the concrete is solidified, the part of the transverse rib 1 exposed out of the wall surface can be directly cut off in the process of removing the template.
When the template is disassembled, the template can generate acting force on the transverse ribs 1 and the vertical ribs 2 when leaving the concrete wall surface, the smaller the bonding force between the transverse ribs 1 and the vertical ribs 2 and the concrete is, and the easier the acting force is, the transverse ribs 1 and the vertical ribs 2 are pulled off from the concrete wall surface together. In this embodiment, the tip of horizontal muscle 1 is inwards protruding in erecting muscle 2, therefore after the post-cast concrete solidification, horizontal muscle 1 protrusion can produce stronger adhesive force in that part of erecting muscle 2 with the concrete, avoids horizontal muscle 1 and erects muscle 2 and is taken out from the concrete wall when demolising template 5, thereby leaves the waterproof performance of hole structure influence wall body on the wall. And horizontal muscle 1 in this application and perpendicular muscle 2 are made by metal material, and it can not produce adverse effect to the waterproof performance and the intensity of concrete wall in concrete wall to be pour.
In order to ensure the bonding force between the transverse bar 1 and the concrete, the length of the transverse bar 1 extending inwards out of the vertical bar 2 is more than or equal to 5cm. The size of the vertical ribs 2 is matched with that of the transverse ribs 1, and the length of the upper ends and the lower ends of the vertical ribs extending out of the transverse ribs 1 is larger than or equal to 3cm.
Fixed inferior stupefied 4 and fixed main stupefied 5 are used for carrying out the reinforced beam structure to the template, and fixed main stupefied 5 that uses when building formwork is the round steel, consequently choose for use with its profile fit's butterfly buckle 3, the upper and lower both sides of butterfly buckle 3 can compress tightly two fixed main stupefied 5 that have circular cross-section simultaneously under the effect of nut 4.
In this embodiment, the threaded section is provided over the entire length of the transverse rib 1, so that the nut 4 can be fitted from the other end without being affected by which end the vertical rib 2 is welded. This structure has another advantage in that: when the length of the transverse bar 1 is longer, after a part of the transverse bar is buried in the concrete wall, the cut part can still be used as the transverse bar 1 again, and only the bar section matched with the nut 4 can be changed when the transverse bar is used again. It will of course be appreciated that in other embodiments, where only a small section of the transverse web 1 is provided with a threaded section which engages with the nut 4, it may be desirable to make the diameter of the section of the rod outside the threaded section smaller than the internal diameter of the nut 4 so that the nut 4 can be fitted onto the threaded section from the outside.
