DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

The wall 1 is L-shaped, and a template 2 is supported on the facade of the wall 1. The template 2 is composed of a negative corner template 2-1, a head template 2-2 and a facade template 2-3.

[0030] The inner side of the inner corner template 2-1 of the wall 1 is provided with an inner corner reinforcement positioner 3, which is arranged along the height of the wall and is arranged in three layers. The number of layers of the inner corner reinforcement positioner 3 is determined according to the height of the wall. The inner corner reinforcement positioner 3 is mainly composed of a lower positioning frame 3-1, an upper positioning frame 3-2, an inner corner column 3-3 and a support rod 3-4 ( Figure 3 , Figure 4 As shown), the lower positioning frame 3-1 and the upper positioning frame 3-2 are both right-angled triangles. The right-angled sides of the lower positioning frame 3-1 and the upper positioning frame 3-2 are made of 40mm×40mm×2.5mm square steel with a length of 200mm. The hypotenuse material is 40mm×40mm×2.5mm square steel. The material of the internal angle column 3-3 is 40mm×40mm×2.5mm square steel with a length of 1.2m. The length of the internal angle column 3-3 can be adjusted according to actual construction.

[0031] The lower positioning frame 3-1 and the upper positioning frame 3-2 are arranged in parallel, and three vertical internal corner columns 3-3 are welded between the lower positioning frame 3-1 and the upper positioning frame 3-2. The three internal corner columns 3-3 are respectively located between the three corners of the two positioning frames, and horizontal support rods 3-4 are welded between adjacent internal corner columns 3-3. The support rods 3-4 are located in the middle of the internal corner columns 3-3. The two right-angled sides of the internal corner fixing positioner 3 are close to the internal corner template 2-1. The single-side width of the internal corner fixing positioner 3 is 200mm, and the weight of a single internal corner fixing positioner 3 is 20-30kg, which is convenient for workers to transport.

[0032] The end cap fixing positioner 4 is placed at the end of the end cap template 2-2 at both ends of the wall 1. The end cap fixing positioner 4 is mainly composed of a lower bracket 4-1, an upper bracket 4-2, an end cap column 4-3, a reinforcing rod 4-4 and a vertical rod 4-5 ( Figure 5-Figure 7 As shown). The lower bracket 4-1 and the upper bracket 4-2 are both U-shaped, the bottom rod and the side rod 4-1-1 of the lower bracket 4-1 are made of 40mm×40mm×2.5mm square steel, and the head column 4-3 is made of 40mm×40mm×2.5mm square steel.

[0033] The lower bracket 4-1 and the upper bracket 4-2 are arranged in parallel, and four end columns 4-3 are welded between the corners and ends of the two brackets. Horizontal reinforcing rods 4-4 are welded between adjacent end columns 4-3. The reinforcing rods 4-4 are located in the middle of the end columns 4-3. Vertical rods 4-5 are welded between the reinforcing rods 4-4 and the side rods 4-1-1 of the bracket. The end fixing positioner 4 is a U-shaped frame as a whole to ensure the overall rigidity and stability of the device. The end fixing positioner 4 is covered on the ends of the end templates 2-2 at both ends of the wall 1. The width of both sides of the end fixing positioner 4 is 200-250mm, and the weight of a single component is 20-30kg, which is convenient for workers to transport. The height of the end fixing positioner 4 is equal to the height of the inner corner fixing positioner 3, and the end fixing positioner 4 is arranged in three layers.

[0034] Six layers of horizontal main purlins 5 are arranged between the internal angle reinforcement positioner 3 and the end-cap reinforcement positioners 4 at both ends of the wall 1. The main purlins 5 are double steel pipe structures. The end-cap template 2-2 is provided with six layers of tension bolts 6. The tension bolts 6 penetrate the end-cap template 2-2. After the ends of the tension bolts 6 penetrate the main purlins 5, 3-shaped fasteners 7 are installed. The 3-shaped fasteners 7 are used to position and fix the main purlins 5. The tension bolts 6 on the outside of the 3-shaped fasteners 7 are installed with nuts. The inner ends of the main purlins 5 on the same layer extend into the internal angle reinforcement positioner 3 and overlap. The overlapped main purlins 5 in the internal angle reinforcement positioner 3 are connected by cross fasteners 8. Right-angle fasteners 9 are arranged at the bottom of both ends of the main purlins 5 of each layer. The right-angle fasteners 9 are arranged vertically. The right-angle fasteners 9 are connected to the internal angle columns 3-3 or the end-cap columns 4-3 by bolts. The right-angle fasteners 9 improve the stability of the main purlins 5. A plurality of vertical secondary purlins 10 are installed between the main purlin 5 and the facade formwork 2 - 3 on the inner side of the wall 1 . The secondary purlins 10 are made of square tubes or square steels and are arranged at intervals.

[0035] The construction process of this embodiment is: erect the first layer of internal corner reinforcement positioners 3 and head reinforcement positioners 4, support the first row of main keels 5, install secondary keels 10, insert the secondary keels 10 one by one, and set wooden secondary keels 10 at the vertical joints of the template, and the spacing of the skipped keels 10 meets the spacing requirements of the scheme design. Install the second layer of internal corner reinforcement positioners 3 and head reinforcement positioners 4, install the main keels 5 layer by layer, and the main keels 5 should be inserted into the internal corner reinforcement positioners 3 at the internal corners to ensure that the straight section of the internal corner reinforcement positioners 3 is parallel to the wall 1.

[0036] Install and reinforce the tension bolts 6 layer by layer, and set a row of tension bolts 6 vertically at a distance of 120mm from the end of the wall. The tension bolts 6 are in close contact with the head column 4-3 of the head reinforcement positioner 4 to resist the outward movement of the end components of the wall. Right-angle fasteners 9 are set at the internal angle reinforcement positioner 3 and the head reinforcement positioner 4, and the right-angle fasteners 9 are locked with the internal angle column 3-3 or the head column 4-3 to ensure the purpose of resisting the outward movement of the end components of the wall.

[0037] The height of a single component of the internal angle reinforcement positioner 3 and the head reinforcement positioner 4 of the utility model is set at 1.-1.8m, which is convenient for the construction of walls with a floor height of 2.8-3.1m, and this height can ensure that there are at least two main keels 5 in each section to fix the components, so as to avoid the components being too short and causing only one main keel to be reinforced. The height of a single component is 1-1.8m, the single-side width of the internal angle component is 200mm, the width of both sides of the head reinforcement positioner 4 is 200-250mm, and the weight of a single component is 20-30kg, which is convenient for workers to transport. The height and width of the components can meet the needs of removing the wall formwork in advance when the inner frame is not removed, and removing and transporting the components separately. The components are selected from materials discarded from the on-site keels, so while meeting the requirements of on-site component reinforcement, they have good integrity with the structure due to their consistent size.

[0038] According to the comparison of actual data on site, after the project adopted the internal and external corner template fixing positioner, the problems of wall end mold expansion and internal corner deformation were fundamentally controlled, and the construction quality was improved while achieving the purpose of recycling construction waste, reducing costs and increasing efficiency. The data comparison before and after the use of the internal corner fixing positioner is shown in Table 1, and the data comparison before and after the use of the head fixing positioner is shown in Table 2.
