Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of prefabricated beam plate manufacturing, in particular to a beam plate end template fixing and clamping device. BACKGROUND

[0002] The so-called T beam is a load-bearing structure, which is combined by the upper flange and beam rib of reinforced concrete. This beam bridge is called T beam because its main beam cross section shape is similar to the English letter "T". In the structural design of T beam, the compression zone of the cross section usually uses concrete with good pressure resistance to make the flange plate, and this flange plate is also used as the bridge deck. As for the tensile zone, it is through the steel bar or prestressed steel bar to bear the tension. The design of T-shaped cross section has certain advantages. With the increase of the width of the wing plate, the height of the compression zone can be reduced accordingly, and the internal force couple arm will increase, which helps to reduce the required tensile steel area, so as to achieve the purpose of optimizing the structure.

[0003] In modern bridge construction, the design and construction technology of T beam are constantly progressing. In order to protect the end of T beam, the end template of T beam will not be removed immediately during the form removal process, but will be clamped and fixed to prevent the end from being damaged or deformed until the maintenance process of T beam is completely finished. In the prior art, in order to prevent the end template from separating from the T beam, a support is usually used to abut against the end template. However, this traditional fixing method has certain limitations, because the end template is arranged obliquely relative to the T beam bottom support and the two side walls of T, and only by abutting can not completely guarantee the stability of the end template, sometimes it will appear loose, resulting in poor fixing and clamping effect. Therefore, there is still room for improvement in this field, and further technical innovation is needed to improve the fixing effect of the end template. UTILITY MODEL CONTENTS
