Wherein, the middle reinforced square timber is evenly arranged along the width of the single shaping template, and the width is between 10cm and 15 cm. The structure reduces the number of the joints on one hand and is beneficial to increasing the construction speed on the other hand;
as shown in fig. 4, 5 and 6: liang Ce a single block of shaped templates. The width of the Liang Ce single shaping template is designed to be the height of the beam, the thickness of the floor slab and the thickness of the floor slab, namely, the single shaping template on the beam side has no standard width, and the specific width is determined according to the height of the beam and the thickness of the floor slab. The length is equal to the beam design length. The long side reinforced square timber is arranged along the length of the wall body block template. In the long-direction reinforced square timber at the two sides, the square timber at one side contacted with the floor slab template is flush with the edge of the template, and the reinforced square timber at the other side deviating from the floor slab protrudes out of the beam side template by 0.5cm. The short side reinforced square timber is arranged between the long through square timber, and the outer side of the square timber is flush with the edge of the template. The middle reinforced square timber is perpendicular to the beam body in length direction and is uniformly arranged at a distance of 30 cm. The direction of the long side of the reinforced square timber is perpendicular to the template so as to strengthen the moment of inertia of the shaping template;
As shown in fig. 7: and forming a template at the internal corner.

The square timber comprises 001 square timber, 002 square timber, 003 square timber and a plurality of 004 square timber and 005 square timber which are additionally arranged according to the width of the right sides of the cross section of the internal corner shaping template. Wherein, 004 square timber and 005 square timber are evenly arranged according to the distance of 10cm to 15 cm.
Reinforcing templates with the same width as the two sides of the right angle of the cross section of the internal corner shaping template are additionally arranged at two ends of the internal corner shaping template, and reinforcing square timber is arranged at two sides of the right angle of the cross section of the internal corner shaping template along the lower edge of the reinforcing template, so that the integral rigidity of the internal corner shaping template is increased, and the problems of slurry leakage and concrete pouring caused by deformation and warping of the template due to insufficient strength in the construction process are prevented;
the beam bottom shaping template has a structure similar to that of the two-side shaping templates. The device consists of a long-side shaping template and a short-side shaping template. Because the beam width is generally smaller and the cross rod support and the upright post return roof are arranged below the beam bottom template, the middle reinforced square timber is not needed to be additionally arranged.
The concrete construction method comprises the following steps:
the template oil immersion method comprises the following steps: the template approach adopts 1200mm to be x 2400mm to be x 12mm multilayer solid wood paint-free plate, and the front and back of the shaping template is fully coated with engine oil for the first time after the shaping template is processed, so that the engine oil is fully immersed into the template to play a role in enhancing the compactness and rigidity of the shaping template, and play a role in a release agent. And (5) after the engine oil is fully immersed into the shaping template, storing the engine oil in a fixed position for standby. In particular, the reinforced square timber is required to be fully coated with engine oil as the template, so that the template and the square timber are prevented from being deformed differently in the later period, and the using effect of the shaping wood template is prevented from being influenced. Before the shaping template is used, the contact surface of the shaping template and concrete is fully coated with engine oil, the shaping template basically has no concrete attachments after the shaping template is disassembled, and the shaping template can be transported to the next layer for use only by simple cleaning.
The specific working flow is as follows:
1. the construction method of the shear wall shaping wood template comprises the following steps:
step 1, installing a template support;
and 2, installing angle steel and a foam plate. And placing 50mm angle steel according to the shear wall positioning line, wherein one side of the angle steel perpendicular to the wall body is clung to the positioning steel bar. One side of the angle steel is perpendicular to the wall body and clings to the floor, and the other side of the angle steel is parallel and clings to the plate body. A layer of 10mm thick foam board is paved on the angle steel, the bottom of the shaping wall die is tightly pressed on the foam board, and the angle steel and the foam board are combined, so that the effect of effectively preventing slurry leakage can be achieved on one hand. On the other hand, the foam board has certain deformability, and can adjust the height difference caused by floor slab pouring;
and 3, assembling the shear wall shaping template. In the assembly, the shaping template at one side of the shear wall is assembled, and then the shaping template at the opposite side of the shear wall is assembled. And one side of the shear wall is provided with a standard wall single-block shaping template from the end part, and the two sides of the first shaping template at the wall end of the standard wall single-block shaping template are protruded to the outer side of the template by 0.5cm towards the reinforcement square timber. The internal corner uses an internal corner shaping template, and the middle part can properly shrink the size of the single shaping template of the wall body according to actual conditions. The method can enable the non-standard-size wall single-block shaping template to be placed in the middle of the shear wall, and the non-standard-size shear wall single-block shaping template can be tightly connected with the left and right standard-size single-block shaping templates through scientific stress reinforcement measures to generate enough friction force, so that dislocation and deformation of the joints of the wall single-block shaping templates are prevented, and a good pouring effect is achieved.
The shear wall end uses a shear wall end shaping template. The outer side and each side of the square timber are reinforced by 0.5cm beyond the edges of the templates along the long side of the shaping templates at the wall end of the shear wall, and the first shaping templates at the wall end of the standard wall single-block shaping templates are matched with the protruding templates of the square timber along the long side of the adjacent side of the shaping templates at the wall end. In assembly, the wall end shaping template and the wall single shaping template are mutually meshed at the initial position of the wall end of the shear wall (shown in figure 8). And clamping the two templates at the wall end of the shear wall by using step by step, and carrying out preliminary reinforcement.
The single wall body shaping template and the single wall body shaping template, the single wall body shaping template and the shear wall shaping template under the beam, the single wall body shaping template and the shear wall end shaping template, the single wall body shaping template and the internal corner shaping template, and the shear wall end shaping template and the internal corner shaping template are reinforced by steps. The right side of the former single shaping template is reinforced by two buckles at the two ends in a step-by-step manner, the other end is reinforced at the left side of the latter single shaping template, the reinforcement mode is similar, and the step-by-step vertical distance is 50cm (shown in fig. 9). The friction force between the block templates is enough, the splicing is firm, and the deformation between the block templates is prevented, so that the slurry leakage and dislocation of the wall are caused.
After the assembly of the shaping template of the shear wall on one side is completed, the shaping template of the shear wall on the other side is assembled with the shaping template of the wall end of the shear wall;
the junction of the upper part of the beam side die and the slab die of the floor slab is reinforced by nails from the upper part of the slab die, and the lower part of the beam side die is reinforced by steps, so that the beam side die is reinforced and stabilized. And the lower side of the beam side die is reinforced by 0.5cm, the square wood protrudes out of the beam side die plate, and is matched with a Liang Cexiao component, and after the concrete pouring is completed and the side die is removed, the side die can be removed from the position without damaging the whole die plate. On one hand, the concrete curing is facilitated, on the other hand, the cleaning can be timely performed, and slag inclusion caused by the fact that the side mold is mixed in the concrete is prevented.
Because Liang Cemu template position is higher, upper portion and board mould are consolidated with the nail, receive position and reinforcement mode's influence when dismantling, are more liable to damage relative to other positions. To this problem, this patent adopts "house little big-keeping" thinking, carries out simple transformation to beam side form tip. And (3) at two ends of the beam side shaping wood template, respectively inwards shrinking the multi-layer solid wood paint-free boards by 10cm, and enabling 10cm, which does not reach the ends, to exist in the form of beam side small-size components. The length of the beam side mould small component is the same as that of the beam side mould, the width is 10cm, and the used material is a multilayer solid wood paint-free plate with the same integrity. And when the method is used for integral assembly, the control assembly tightness is strictly controlled, so that the influence of quality defects caused by the joint is basically ignored after the later pouring, and the pouring surface is smooth and has no slurry leakage and platform lifting phenomenon.
After the assembly of the splice joint is tight, nails are used for reinforcing every 10cm, the long side direction of the Liang Cexiao component is reinforced by the nails for reinforcing square timber of the beam side shaping template which is in contact with the nails, and at the same time, the number of the nails on each side of the beam side small component is not less than 3 as much as possible, so that the stability of the beam side small component is ensured, and the requirement of main stress is met. The lower end of the beam side die small member is identical to the long-direction reinforcing square wood facing away from the floor direction of the beam side reinforcing square wood, the whole template is protruded by 0.5cm, and the lower end is flush with the long-direction reinforcing square wood. On the one hand, when the small member of the beam side die is stressed, the stressed force can be transmitted to the integral beam side shaping template through the long-direction reinforcing square timber, so that the long-direction reinforcing square timber deviating from the lowest end of the floor slab is prevented from being taken as a main stress point, and the long-direction reinforcing square timber is directly loosened under the action of force, so that the template is damaged. On the other hand, the lower extreme of beam side form small member and the long direction of beam side reinforcement square timber that deviates from the floor direction consolidate square timber parallel and level, also can make the whole standard design effect of beam side reinforcement square timber better, prevent protruding small member and accomplish construction difficulty and potential construction danger.
Under the effect of Liang Cexiao component, when the girder side shaping template was dismantled, both ends were regard Liang Cexiao component as main stress point, make girder side shaping template preliminary not hard up under the effect of main stress point, later regard girder side shaping template to deviate from the protruding 0.5cm of the long direction reinforcement square timber of floor as secondary stress point, carry out final dismantlement with girder side template. The secondary method can basically take the beam side small component as a damage range, in the turnover of the template, if damage occurs, the beam side small component is simply replaced by disassembling the beam side small component, and the template can be reused by brushing engine oil with the whole body before the next use, so that the method is convenient and quick, greatly saves the cost while ensuring the engineering quality, reduces the consumption of materials and manpower, and quickens the construction progress.
Step 4, installing a through-wall bolt and an inner sleeve;
and 5, installing a horizontal double steel pipe. The horizontal double steel pipes are uniformly reinforced along the height direction of the wall, wherein the horizontal double steel pipes are 200mm from the floor, and the distance between the horizontal double steel pipes is 500 mm. The two buckles of the 3-shaped clamp on the split bolt are respectively fixed on the two steel pipes of the double steel pipes, and the lower part of the shear wall is reinforced by the double bolts within 1/3 of the height. And if a corner exists at the end part of the wall body, the split bolt passes through the split bolt after hole forming, and a sleeve is used. The end part of the wall column is reinforced by double steel pipes, the double steel pipes at the end part correspond to the through-length split bolts, the through-length split bolts are placed on the upper parts of the double steel pipes, and 3-shaped buckles on the through-length split bolts are respectively fixed on two sides of the double steel pipes at the end part;
step 6, preliminarily reinforcing the shaping template;
step 7, adjusting the perpendicularity of the shaping template;
and 8, finishing reinforcement.

The height is +300mm, including the lower part protruding floor connects the stubble department 200mm to set up one leak protection and will rise the mould split bolt, upper portion is higher than the floor and pours the face 100mm. The middle main body shaping template is different from a wall single shaping template, and is a whole shaping template, namely, the template in one wall of the elevator shaft is a whole, and the middle main body shaping template is formed by non-later-stage assembly. After the width and the height of the middle shaping template are obtained, the template within the width multiplied by the height is used as a whole to manufacture the shaping template. The manufacturing method is basically the same as that of the single wall shaping template, and the side reinforced square timber in the direction parallel to the floor is generally arranged along the length of the main body shaping template in the middle of the elevator shaft, and the outer side of the square timber is flush with the edge of the template. The side reinforced square timber is arranged between the long through square timber and the floor vertical direction, the outer side of the square timber is parallel and level with the edge of the template, and the reinforcing distance is 15 cm.
The second part is an elevator shaft internal corner shaping template which plays a role in effective connection. The external shape of the internal corner shaping template is the same as that of the shear wall internal corner shaping template, and the difference is that the widths of two right-angle sides of the elevator shaft internal corner shaping template are consistent, and the two right-angle sides cannot have large differences, and are generally set to be 200mm on each side, so that the problem that the two adjacent sides are inconsistent in strength during integral lifting, and the elevator shaft integral shaping template is damaged is avoided. The length is the same as the main body shaping template in the middle of the elevator shaft.
The third part is the elevator shaft shaping template assembling reinforcement. The elevator shaft shaping template assembly reinforcing member is a right-angle triangle template, after the elevator shaft middle main body shaping template is spliced with the elevator shaft internal corner shaping template, four corners at the upper part of the elevator shaft template are reinforced on the shaping template by nails.

The sizes of the No. 1 b side, the No. 2 b side, the No. 3 b side and the No. 4 b side are (the design size of the elevator shaft-500 mm)/2. The size of the assembled reinforcement of the elevator shaft shaping template at the position a and the position a is the same as the design size.
The fourth part is an integral shaping template lifting buckle of the elevator shaft. The setting of the integral shaping template lifting buckle of the elevator shaft is simple and effective. When the main body shaping template in the middle of the elevator shaft is arranged with the reinforced square timber in the vertical direction of the floor, a hole with the diameter of 16mm is drilled on the reinforced square timber in the middle of the template at the position 500mm away from the top of the template, and reinforcing steel bars matched with the hole are inserted into the hole after the hole is drilled, so that the manufacturing is completed. The elevator shaft integral shaping template lifting buckles are arranged in number 3 and are respectively positioned in the middle of number 1 and number 2, in the middle of number 1 and number 3 and in the middle of number 2 and in the middle of number 4.
In order to prevent slurry leakage and dislocation at the upper and lower layers of joints of the elevator shaft, the lower part of the elevator shaft shaping template protrudes 200mm from the joints. And uniformly and pairwise pulling bolt holes at a distance of 450mm from the bottom of the template, and fully pasting foam adhesive tapes on the bottom of the elevator shaft shaping template. Because the two split bolts are added for reinforcement, the adhesion degree between the shaping template and the surrounding walls of the lower elevator shaft is obviously increased, so that the phenomenon of staggering is avoided, and the phenomenon of slurry leakage is obviously improved. The bottom foam adhesive tape is adhered to the walls around the elevator shaft, so that the phenomenon of slurry leakage can be effectively prevented.
During construction, the assembly is carried out according to the assembly structure shown in fig. 12-15. The assembly is completed by pre-assembly, and the method is used for integral hoisting.

In order to strengthen the integrity and rigidity of the elevator shaft shaping template, the elevator shaft shaping template reinforcing members are adopted on the upper parts of the elevator shaft shaping template and the elevator shaft shaping template. Under the dual support of the compression friction force provided by the step-by-step and the stability provided by the reinforcing member of the elevator shaft shaping template, the required integrity of the elevator shaft shaping template can be met. The size of the reinforcing member of the elevator shaft shaping template is subtracted by 500mm to set the lifting buckle of the elevator shaft integral shaping template. During reinforcement, the reinforcement mode of the integral elevator shaft shaping template is the same as that of the shear wall shaping template, the distance between the bottom of the elevator shaft shaping template and the left and right is 500mm, a pair of opposite-pulling bolt holes corresponding to two sides of the wall body are preformed, and whether an inner sleeve is used or not is determined according to drawing requirements. A row of opposite-pull bolt holes are uniformly arranged at an upper-lower interval of 500 mm. The 3-shaped buckle of the split bolt is buckled with two double steel pipes. Reinforcement is performed in this way. And after the concrete pouring is completed, the reinforcing members are removed one by one. Because the excellent performance of this kind of shaping wooden template, the elevator shaft shaping template does not produce obvious adhesion with the wall body all around of elevator shaft, when waiting that the next floor needs to carry out elevator shaft template construction, uses the tower crane, carries out effective connection with the whole shaping template lifting button of 3 elevator shafts that the whole shaping template of elevator shaft set up with tower crane hook, uses the tower crane slowly to hang out the elevator shaft shaping template to the safe position, carries out once full coating machine oil, alright with its lifting according to the service behavior use.
