[0001] The present application relates to the field of turnover material accessories for formwork engineering in building construction, and specifically to a internal angle back rib connector. Background Art
[0002] During the construction of concrete walls and columns, it's necessary to first construct a casting formwork, which is then reinforced with structures like keels and back ribs to ensure the final concrete pouring effect. In the construction process of existing traditional wooden formwork, the reinforcing back ribs of wall and column casting formwork generally use Ø48 steel pipes, and none of them are equipped with internal corner locking devices for connection. As a result, the quality of the internal corners of walls and columns is difficult to achieve without plastering. A smaller number of wall column reinforcements are made with aluminum formwork, and the internal corners are integrated with the reinforcement back ribs. These reinforcement back ribs only serve the purpose of reinforcing the back ribs, resulting in high amortization fees. Utility Model Content
[0003] In response to the shortcomings of the existing technology, the present application provides a connecting piece for the internal corner back ribs, which can not only ensure the fixation and connection effect of the horizontal back ribs of the combined square tubes, but also greatly ensure that the bearing pressure of the combined square tube back ribs is more than 50% higher than that of the Ф48 steel tube back ribs, and better ensure that the internal corners of the wall columns achieve the quality of no plastering, thereby effectively reducing the construction cost and greatly promoting the development and progress of the industry.

[0006] Preferably, the transverse plate and the longitudinal plate are arranged adjacent to each other and are perpendicular to each other; the width of the transverse plate and the longitudinal plate is the same as the structural width of the overlapping portion extending out from the L-shaped plate head.
[0007] Preferably, the inner limiting edges are arranged on the inner side edges of the transverse plate and the longitudinal plate, and the inner limiting edges on the transverse plate are arranged to face the inner limiting edges on the longitudinal plate.
[0008] Preferably, the outer L-shaped edge is arranged on the outer sides of the transverse plate and the longitudinal plate, and the outer L-shaped edge on the transverse plate is arranged opposite to the outer L-shaped edge on the longitudinal plate.

[0027] Example 1
[0028] like Figure 1-3 As shown, a female angle back rib connector includes two side panels 100 arranged opposite to each other, a U-shaped rib 200 spanning the two side panels 100 and fixed as one with the two side panels 100, and a reinforcing plate 300 respectively arranged on the two side panels 100 and fixed as one with the two side panels 100.
[0029] The side panel 100 is composed of an L-shaped panel head 101, a horizontal panel 102 and a vertical panel 103 respectively arranged on two adjacent long sides of the L-shaped panel head 101, a plurality of fixing holes 104 respectively arranged in rows on the horizontal panel 102 and the vertical panel 103, an inner limit edge 105 respectively arranged on the horizontal panel 102 and the vertical panel 103, and an outer L-shaped edge 106 respectively arranged on the horizontal panel 102 and the vertical panel 103.
[0030] The purpose of setting the fixing holes is to cooperate with the back ribs. When a fixing structure such as a pin is inserted from the fixing hole on one side, passes through the fixing hole of the back rib and then exits from the fixing hole on the other side, the back rib and the product of the present application can be effectively fixed together. When fixing the back ribs, at least one pin that cooperates with the fixing hole on the horizontal plate or vertical plate of the product of the present application needs to be set in the fixing hole at the end of the back rib. As a preference, setting two pins that cooperate with the present application on one back rib can further improve the stability of the back rib fixation and more effectively reduce the probability of deformation of the product.
[0031] The purpose of setting a plurality of fixing holes is to adjust the fixing position of the back rib according to the actual insertion length of the back rib, which effectively improves the flexibility of the back rib product.
[0032] The transverse plate 102 and the longitudinal plate 103 are adjacently arranged and perpendicular to each other; the width of the transverse plate 102 and the longitudinal plate 103 is the same as the structural width of the extended and overlapping portion on the L-shaped plate head 101.
[0033] In order to improve the force-bearing capacity of the product, the transverse plate, longitudinal plate and L-shaped plate head are an integrated structure.
[0034] The inner limiting edges 105 are arranged on the inner sides of the transverse plate 102 and the longitudinal plate 103 , and the inner limiting edges 105 on the transverse plate 102 and the inner limiting edges 105 on the longitudinal plate 103 are arranged to face each other.
[0035] The inner limit edge can effectively fit on the outer edge of the back rib when the back rib is inserted, so as to facilitate the positioning of the back rib. At the same time, it can effectively disperse the interaction force evenly on the outer edge of the back rib, avoiding deformation of the back rib due to excessive concentration of force.
[0036] The outer L-shaped edge 106 is arranged on the outer sides of the transverse plate 102 and the longitudinal plate 103 , and the outer L-shaped edge 106 on the transverse plate 102 is arranged opposite to the outer L-shaped edge 106 on the longitudinal plate 103 .
[0037] There are four U-shaped ribs 200 , two of which span two transverse plates 102 and have their ends inserted into the outer L-shaped edges 106 of the two transverse plates 102 , and two of which span two longitudinal plates 103 and have their ends inserted into the outer L-shaped edges 106 of the two longitudinal plates 103 .
[0038] The setting of the outer L-shaped edge can not only facilitate the positioning and limiting of the U-shaped ribs, but also effectively prevent the U-shaped ribs from being deformed due to external forces during use, further ensuring the force-bearing capacity of the product and improving the use effect of the product.
[0039] The reinforcing plate 300 is composed of an L-shaped reinforcing piece 301 and limiting strips 302 respectively provided on two adjacent long sides of the L-shaped reinforcing piece 301 .
[0040] The size of the L-shaped reinforcing piece 301 is the same as that of the L-shaped plate head 101 , and the width of the limiting strip 302 is the same as that of the transverse plate 102 and the longitudinal plate 103 .
[0041] The L-shaped reinforcement plate can effectively improve the force-bearing capacity at the L-shaped board head position, and the limit strip will extend into the end positions of the horizontal board and the vertical board when set, thereby further improving the load-bearing capacity at the connection position between the L-shaped board head and the horizontal board and the vertical board, better improving the stability of the product and further reducing the chance of product deformation.
[0042] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.
[0043] In addition, the above-mentioned specific embodiments are merely illustrative.

Those skilled in the art should understand that the specification and drawings of this utility model are illustrative and do not constitute limitations of the claims.
