Embodiment Construction

[0038] See Figure 1 to Figure 6, as an embodiment of the present invention, the module for constructing the pouring cavity to strengthen the strength of the cement column includes an upper placement surface 1, a lower placement surface 2, a pair of end surfaces 3 and 4, wherein 3 is the left end surface , 4 is the right end surface, an inner surface 5, an outer surface 6, the inner surface 5 and the outer surface 6 are coaxial semi-cylindrical arc surfaces. There is a recess 11 in the middle of the upper placement surface 1 and the lower placement surface 2, and two convex parts 12 are symmetrically arranged on both sides of each of the recesses 11, and each of the recesses 11 is in the circumferential direction. The length is the sum of the lengths of the two protrusions 12 in the circumferential direction; the protrusions 12 of adjacent modules are formed in a shape suitable for being embedded in the recess 11 and complementarily engaged. A concave platform 121 along the c...

Abstract

The invention relates to a method for reinforcing the strength of a concrete column and a reinforcing module, wherein the reinforcing method comprises the following steps: a, using a cement module to surround the concrete column so as to assemble a layer of annular shuttering; b, piling up the annular shuttering layer by layer until reaching the preset height so as to form a pouring cavity between the outer surface of the concrete column and the inner surface of the shuttering; c, pouring concrete into the pouring cavity; and d, solidifying the concrete to form an integral body with the annular shuttering and the reinforced concrete column as a part of a bearing structure. Because the reinforcing module finally becomes a part of the bearing structure permanently, the method and the reinforcing module have remarkable reinforcing effect and can repair a telegraph pole with the broken appearance effectively; furthermore, the method and the reinforcing module thoroughly solve the technical problem that in the prior art the reinforcing module is separated from a structure to be reinforced.

Description

technical field [0001] The invention relates to the existing cement column, in particular to a method for strengthening the strength of the cement column and a module used therein. Background technique [0002] In order to strengthen existing structures such as concrete columns and beams to cope with their aging, two methods are used in the prior art, one is to strengthen the hollow part of the concrete structure; Repair and strengthen the surface of concrete columns and beams. [0003] The first method of strengthening the hollow part is disclosed by the invention patent with the publication number CN1438101A, which specifically discloses a method for strengthening concrete utility poles. The utility pole has an annular side wall, an internal hollow structure, and an annular A penetrating opening part formed at a position of the side wall, the method injects filling material into the inner hollow part of the utility pole through the opening part on the side wall of the uti...
