Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a structure for preventing misalignment at a joint of a composite plate. Background Art

[0002] In today's prefabricated buildings, prefabricated PC components (i.e., composite slabs) are often used on floors. After the wall, column, and beam slabs are installed, the composite slabs are hoisted and placed on the slab surface. The steel bars extending from the wall, column, beam, and composite slabs are then staggered and anchored before grouting. However, the design of the nodes between composite slabs and between composite slabs and cast-in-place structures must refer to national standard drawings and take into account the operability of on-site construction to ensure construction quality while avoiding difficulties in on-site construction caused by complex connection nodes.

[0003] According to the existing technology, the lower end of the cast-in-place connection belt at the intersection of the composite slabs is flat, and the bottom surface structure of the composite slabs is also flat. The disadvantages are: ① During the pouring process, due to mechanical shaking or uneven installation, the cast-in-place connection belt will bulge and need to be polished later. It is difficult to operate and the cost is high; ② The cast-in-place connection belt at the intersection of the composite slabs is prone to cracking, which requires later repairs. In order to solve this problem, we have developed a new type of grooved glue plate method for prefabricated composite slabs to prevent cracking based on the original composite slabs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical defects and provide an anti-misalignment structure at the joints of the composite panels, thereby avoiding the problems that the original composite panels are difficult to position, difficult to install, and difficult to ensure the flatness of the panel surfaces at the joints, reducing the construction difficulty, and making it easier to ensure the construction quality, making the aluminum mold construction more reasonable and economical, and improving the construction quality without affecting the construction period or causing later chiseling and patching.

[0005] In order to solve the above problems, the technical solution of the utility model is: a structure for preventing misalignment at the joint of a composite plate, comprising a composite plate, a casting connection belt is provided between two composite plates, a steel bar is provided inside the casting connection belt, and a groove is provided at the bottom of one end of the composite plate close to the casting connection belt;

[0006] An aluminum template is fixedly connected to the composite plate.

[0007] Furthermore, a rubber pressing plate is provided at the upper end of the aluminum template, and the rubber pressing plate is clamped at the bottom end of the composite plate.

[0008] Furthermore, the groove width is centimeters, and the groove thickness is centimeters.

[0009] Furthermore, after casting, the casting connecting belt forms a groove belt with the composite plate, and a mesh cloth is provided inside the groove belt.

[0010] Furthermore, a support column is provided inside the aluminum template.

[0011] The advantages of the utility model compared with the existing technology are:

[0012] (1) The utility model avoids the problems of the original composite panels being difficult to position, difficult to install, and difficult to ensure the flatness of the panel surface at the joints, thereby reducing the construction difficulty, making the construction quality more easily guaranteed, making the aluminum mold construction more reasonable and economical, and improving the construction quality without affecting the construction period or causing the need for chiseling or patching in the later stage.
