And cross operation of installation work of the backdrop system and other civil engineering professions such as scaffold building work is reduced, and construction efficiency is improved. The first supporting rod 421 and the second supporting rod 431 are respectively connected with the internal threaded holes 414 on the two adjacent bolt balls 410 in a threaded manner through a set of positioning threaded pins 231 at two ends, so that the installation work of the awning main body 100 and the supporting main body 400 can be realized, the dismounting is convenient and quick, the fixing effect is good, and the construction efficiency is improved. And after the positioning screw pin 231 is in threaded connection with the internal threaded hole 414, a group of screw pin connecting rods 230 connected with the positioning screw pin 231 are also clamped in the clamping groove 412 at the same time, so that the fixing effect of the bolt ball 410 is further improved. After the screw pin connecting rod 230 is clamped in the clamping groove 412, the friction between the inner wall of the clamping groove 412 and the screw pin connecting rod 230 is increased by utilizing the plurality of groups of anti-slip convex blocks 413 distributed on the inner wall of the clamping groove 412, and the fixity between the first supporting rod 421 or the second supporting rod 431 and the screw bolt ball 410 is increased.
Referring to fig. 10-11, the support anchor is positioned prior to construction and comprises a pre-buried plate 601, an anchor bar 603, a support and a bolt structure. Embedding the support embedded part before pouring and tamping foundation concrete, and after binding the civil engineering steel bars, controlling the embedded part to be embedded by using a positioning template according to the position and the positioning size of a drawing according to the requirements of a design drawing; in order to prevent the embedded part from shifting in the concrete pouring process, the embedded part should be permanently fixed. The concrete method can adopt angle steel L40X3 or steel bars to manufacture a fixed bracket, and the fixed bracket is welded with a steel bar net (preferably a main steel bar); and then the embedded part and the fixed bracket are connected (welded) and fixed. And immediately measuring and rechecking after the embedded part is positioned. And after meeting the requirements of specification and design allowable deviation, the next working procedure can be handed over to perform concrete pouring construction. Before installation, the net frame constructor dispatches experienced constructors for construction, and arranges professional measuring staff for tracking measurement. And rechecking the measurement record of the size of the embedded part of the support, and installing the net rack after meeting the design requirement. The concrete strength meets the design strength, and the structural axis and the support embedded steel plate are required to be accepted and qualified. The embedded part is required to be: the horizontal offset is not more than 15mm, the height difference of adjacent embedded parts is not more than 5mm, the highest and lowest height difference is not more than 30mm, and the inclination of the plate surface is less than 1 degree; after the net frame assembly and roof board installation are completed, the deflection value of the net frame assembly and roof board installation should be measured, and the measured deflection value should not exceed 1.15 times of the corresponding design value. The embedded steel plate of the support surface of the net rack support should be flat, the position and elevation must be accurate, the position deviation is not more than 15mm, the adjacent height difference is not more than 5mm, and the highest and lowest height difference is not more than 15mm.
Although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application.
