Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Example (b):

as shown in fig. 1, an arch bridge stone arch coupon fixing structure comprises an arch coupon template 1, wherein the arch coupon template 1 is used for guiding the setting shape and position of a stone arch coupon, the dislocation or dislocation phenomenon easily generated in the subsequent arch coupon block material 2 splicing process is avoided, and the structural integrity of a construction product is guaranteed. The arch coupon template 1 is made of wood plates or bamboo plates, so that materials are convenient to obtain, recycling is convenient, and rapid construction is facilitated. The upper portion concatenation of arch coupon template 1 has laid arch coupon bulk 2, and the quantity of arch coupon bulk 2 is a plurality of, and is decided according to actual construction conditions, for the ease of quick location and concatenation, can carry out corresponding serial number and classification to arch coupon bulk 2 according to the design drawing.

As shown in fig. 1 and 2, a buckle reserved hole 3 is obliquely arranged in one side of each arch coupon block 2, and is used for embedding a corresponding steel bar buckle 6. One side that the arch coupon bulk material 2 deviates from arch coupon template 1 is provided with reinforced concrete arch ring 4, and reinforced concrete arch ring 4 includes framework of steel reinforcement and concrete (structure as an organic whole in the picture, do not draw both respectively), pours concrete shaping promptly behind the framework of steel reinforcement ligature overlap joint in the work progress. The steel bar framework comprises a connecting medium steel bar 5, the connecting medium steel bar 5 is used for sleeving a steel bar buckle 6, the distance between the connecting medium steel bar 5 and the bottom end of the reinforced concrete arch ring 4 is 40-50 mm, the optimal stable supporting strength is guaranteed, and the reinforced concrete arch ring 4 can not be separated.
