The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
A kind of structure of on reinforced concrete upright column, setting up bracket, as shown in Figure 1.Comprise concrete column 1, a side of concrete column 1 is provided with old bracket 2, and described old bracket 2 relative concrete column 1 opposite sides are provided with new bracket 3, and new bracket 3 is built with concrete column 1 concrete and is connected; Concrete column 1, old bracket 2 and new bracket 3 outsides are enclosed with carbon cloth 4.New bracket is provided with pre-embedded steel slab 5 in 3 tops.Be provided with cage of reinforcement 6 in the concrete column 1, concrete column 1 is a hair side 7 with the joint face of new bracket 3, and the outer reinforcement of cage of reinforcement 6 is exposed to outside the hair side 7 (see Fig. 2 step 2.), and hair side 7 surfaces scribble the 1:2 cement paste.3. hair side 7 is provided with step that one group of shear reinforcement 8(that arranges along concrete column 1 vertical direction sees Fig. 2) and one group of bracket reinforcing bar 9 of arranging along concrete column 1 horizontal direction, be provided with one group of bracket stirrup 10(sees Fig. 3 to bracket reinforcing bar 9 outward).Described bracket stirrup 10 and 9 welding of bracket reinforcing bar.New bracket 3 is a C35 concreting body.
Concrete implementation step of the present utility model as shown in Figure 2.
1. step among Fig. 3 is available coagulation soil column 1, and a side of concrete column 1 is provided with old bracket 2.
As the step among Fig. 3 2. shown in, cut a hole into hair side 7 with chisel in old bracket 2 relative concrete columns 1 one sides, and cage of reinforcement 6 outer reinforcements in the existing concrete column 1 be exposed to outside the hair side 7; Simultaneously the end face of existing concrete column 1 is also cut a hole 16-20mm, so that bury pre-embedded steel slab 5 underground.Use the bits and the dust of clear water flush away hair side 7 then, brush the cement paste of one 1:2 again at hair side 7.
As the step among Fig. 3 3. shown in, make a call to the pre-buried via hole 11 of shearing resistance muscle of 8 φ 30 and the pre-buried via hole 12 of bracket muscle of 8 φ 25 in concrete column 1 side with Churn drill.8 pre-buried via holes 11 of shearing resistance muscle are arranged by 4 row, 2 row, and hole depth is not less than 160mm, and line space is 90mm, and column pitch is 200mm; 8 pre-buried via holes 12 of bracket muscle are arranged by 2 row, 4 row, and up hole depth is not less than 240mm, and descending hole depth is not less than 100mm, and column pitch is 90mm, and line space is determined according to the spacing at the bracket reinforcing bar two ends of making in advance; In pre-buried via hole 11 of shearing resistance muscle and the pre-buried via hole 12 of bracket muscle, fill the C35 concrete.
As the step among Fig. 3 4. shown in, 4 shear reinforcements 8 are inserted in the pre-buried via hole 11 of shearing resistance muscle, the reinforcing bar of shear reinforcement 8 usefulness φ 20 is bent into U-shaped, its long edge lengths is 400mm, bond length is 200mm, filling is inserted at the two ends of U-shaped shear reinforcement 8 to be had in the pre-buried via hole 11 of the concrete shearing resistance muscle of C35, waits for the C35 concrete setting.
As the step among Fig. 3 5. shown in, 4 bracket reinforcing bars 9 are inserted in the pre-buried via hole 12 of bracket muscle, the shape of bracket reinforcing bar 9 is corresponding with the shape of bracket outer rim, undersized is in the bracket physical dimension; At 8 spaced bracket stirrups 10 of bracket reinforcing bar 9 outsides welding, form the bracket steel bar framework, every bracket stirrup 10 two ends all with existing concrete column 1 in cage of reinforcement 6 outer reinforcements weld together, filling is inserted at bracket reinforcing bar 9 two ends respectively to be had in the pre-buried via hole 12 of the concrete bracket muscle of C35, waits for the C35 concrete setting.Because the step among Fig. 3 is 5. less, in order to see the arrangement architecture of each reinforcing bar clearly, Fig. 4 is a step partial enlarged drawing 5. among Fig. 3.
As the step among Fig. 3 6. shown in, pre-embedded steel slab 5 is placed on the concrete column 1 top good hair side 7 of cutter in advance, the length of pre-embedded steel slab 5 is 400mm, width is 300mm, thickness is 14mm, pre-embedded steel slab 5 end faces are concordant with the end face of old bracket 2, the bottom of pre-embedded steel slab 5 and 9 welding of bracket reinforcing bar; Use the new bracket 3 of C35 concreting moulding then.
Treat concrete setting be dried to design strength 75% after, as shown in Figure 2, stick on new and old bracket surface with three U types of 1 CFS2-3 monolayer carbon cloth.Also can paste multilayer on four sides as required at new and old bracket.
After adopting structure of the present utility model and construction sequence, well solved the connectivity problem that increases bracket and original post newly, the shearing resistance and the compressive property of newly-increased bracket are good, and fastness bonding between the new and old concrete is good, has improved the shock resistance of factory building and the reliability of use.
