[0018] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection requested by the present application.
[0019] According to GB50007-2011 "Code for Design of Building Foundations", Table 7.3.2 stipulates that the width of settlement joints of buildings above five floors shall not be less than 120mm, and the minimum spacing for formwork reinforcement construction is also 120mm. Therefore, this construction method is suitable for formwork reinforcement in construction joints in narrow spaces (inaccessible to personnel) of buildings with five floors or more.
[0020] like Figure 1-4 As shown: a template reinforcement structure at a construction joint position, which includes wooden strips 1 and fasteners; the wooden strips are longitudinally arranged at intervals on the surface of a template 2, the fasteners are transversely arranged on the upper part of the longitudinal wooden strips, and wooden strips are also transversely arranged at the upper and lower port positions of the template.
[0021] Furthermore, the fastener is a pressure strip arranged on the longitudinal wooden strip.
[0022] Furthermore, the fastener includes two steel bars 3, a tension screw 4 and a mountain-shaped clip 5. The two steel bars are transversely arranged on the upper part of the longitudinal wooden strips. The mountain-shaped clip is fixed on the two steel bars, and fastening is achieved by passing the tension screw through the template.
[0023] Furthermore, it also includes a plurality of reinforcement members, which are vertically welded to two steel bars at intervals for template reinforcement.
[0024] Furthermore, the reinforcement member is a φ10 steel bar.
[0025] Furthermore, steel pipes 7 are welded to both ends of the two steel bars for hanging the formwork and fixing the formwork.
[0026] Furthermore, triangular keys 6 are provided at intervals on the upper parts of the wooden blocks arranged transversely at the upper and lower ends of the template.
[0027] Specifically, the device components used in the present application are composed of a template, a mountain-shaped clip for the tension screw, an ordinary steel pipe, steel bars and nuts.
[0028] The specific construction methods are as follows:
[0029] (1) The first step is preparation. The glued template (915*1830) is molded according to the design drawings.
[0030] (2) The second step is to splice the wood and the formwork. Use 40*90 wood, use the 90mm surface, and arrange it horizontally with a spacing of 200mm to strengthen the formwork. Use horizontal wood at the upper and lower ports to reinforce the formwork.
[0031] (3) The third step is to process the standardized steel pipe fastener. This device consists of two upper and lower φ22 steel bars, a mountain-shaped clip of a φ12 tension screw and a hexagonal nut. The upper and lower points of the concave and convex surface of the mountain-shaped clip are spot welded to the upper and lower two steel bars, and the hexagonal nut 8 is spot welded to the upper and lower straight surface of the mountain-shaped clip 9.
[0032] (4) The fourth step is to fix the fasteners to the formwork. Use the tension screws to tie and fasten the formwork. The fasteners and the formwork must fit tightly without shaking. Use φ10 steel bars and two φ22 steel bars to spot weld vertically for formwork reinforcement. Weld φ48 short steel pipes at the left and right ends for hanging the formwork and fixing the formwork.
[0033] (5) The fifth step is to use a wooden square to process a triangular key at the upper end of the template. The size is determined according to the spacing of the settlement joints, and the horizontal spacing range is 300~500. Function: Make the inner side of the template fit closely with the wall surface 10 and control the verticality of the template.
[0034] (6) The sixth step is to hoist the formwork. Use a tower crane to hoist the processed outer wall formwork to the construction site.
[0035] (7) The seventh step is to tighten the inner screw. On the inner side of the wall construction joint, first use the pre-processed template to close the mold, and then use the tension screw rod to find the outer fasteners from the inside and tighten them.
[0036] The above are only embodiments provided for the present application and are not intended to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
