Problems solved by technology

These methods have been applied in engineering practice to a certain extent, and have shown their respective advantages, but these methods all have a common disadvantage, that is, changing the appearance of structural components. For cultural relics, the first principle of repair and reinforcement is not to change The original state of cultural relics, at this time, none of the above reinforcement methods can meet the requirements

Embodiment 1

[0035] Embodiment 1: A three-dimensional frame reinforcement structure in a large-volume masonry column, such as figure 1 with figure 2 , including a number of parallel first fixing holes 11 set in the existing masonry member 1, square steel pipes 12 pierced in each first fixing hole 11, filling the outer wall of the square steel pipe 12 and the first fixing hole 11 The filling layer 121 between the walls and a number of bushing grouting anchors 13 that pass through the existing masonry member 1 and are perpendicular to the length direction of the square steel pipe 12. One end of each bushing grouting anchor 13 passes through the same plane. Each square steel pipe 12 in.

[0036] Such as figure 1 with figure 2, each square steel pipe 12 and each bushing grouting anchor 13 form a three-dimensional space frame, and the bushing grouting anchor 13 passes through the square steel pipe 12, and the volume of the bushing grouting anchor 13 expands after grouting, so that the bush...

Embodiment 2

[0044] Embodiment 2: a kind of construction method based on above-mentioned embodiment 1, as Image 6 , including the following steps, step 1, according to the vertical force and horizontal force borne by the existing masonry member 1 after reinforcement, determine the cross-sectional area and number of steel pipes required for reinforcement, and the spacing of grouting anchor rods 13 with bushings;

[0045] Step 2, determining the drilling distance and drilling position of the first fixing holes 11 on the top surface of the existing masonry member 1;

[0046] Step 3: Determine the drilling position of the side wall of the steel pipe according to the required spacing of the grouting anchor rods 13 with bushings, and drill the second fixing holes 131 alternately on adjacent surfaces;

[0047] Step 4. After the first fixing hole 11 is drilled, place the square steel pipe 12. The center of the square steel pipe 12 coincides with the drilling center of the first fixing hole 11, so...

Abstract

The invention discloses a three-dimensional frame reinforcement structure in a large-volume masonry masonry column and a construction method, relates to the technical field of structural engineering in the civil engineering industry, and aims to improve the vertical bearing capacity and overall seismic performance of existing masonry components. The purpose of reducing the damage to the appearance of masonry components is that the key points of the technical plan are: including a number of parallel first fixing holes opened in the existing masonry components, square steel pipes pierced in each first fixing hole, The filling layer filled between the outer wall of the square steel pipe and the wall of the first fixing hole, and a number of grouted anchor rods with bushings that are installed in the existing masonry member and perpendicular to the length direction of the square steel pipe, each of the grouted anchors with bushes One end of the anchor rod passes through each square steel pipe located in the same plane.

Description

technical field [0001] The invention relates to the technical field of structural engineering in the civil engineering industry, more specifically, it relates to a three-dimensional frame reinforcement structure inside a large-volume masonry masonry column and a construction method. Background technique [0002] Masonry is one of the traditional building materials in my country. In ancient times, masonry structures were widely used in city walls and pagodas. Since the founding of the People's Republic of China, large-volume masonry columns are still used as the main force-bearing components in industrial buildings and traffic bridges. Large-volume masonry columns generally need to be reinforced due to the following reasons: ①Deterioration of material properties, that is, reduced resistance; ②Increased vertical load, such as changes in use functions; ③Increased seismic fortification category or seismic fortification intensity. [0003] The commonly used reinforcement methods...
