The plywood 4 is bonded with the PVC board 5 through a colloid, and the colloid is resin glue or universal glue.

The size width of the PVC plate 5 is 1-2 mm smaller than that of a single template. The width of the PVC plate 5 is in particular 120mm so that the tightness of the inner interface when the formwork is installed is spread over the PVC plate 5.

The manufacturing method of the pouring mould of the bamboo texture decorative surface concrete wall body comprises the following steps:

1) and manufacturing a single template:

a. vertically and fixedly connecting a plurality of vertical ribs 1 and a plurality of horizontal keels 2 with each other in a crossed manner to form a grid-shaped internal main body, wherein vertical edges on two sides of the internal main body are symmetrically fixedly provided with frames 3, and the end parts of the plurality of horizontal keels 2 are fixedly connected with the frames 3 positioned on the same side;

b. fixing a plywood 4 on one side of the inner body;

2) paving a panel;

a. cleaning the surface of the plywood 4 with the single template manufactured in the step 1), uniformly coating the surface of the plywood 4 with a colloid by using a rubber scraper, and waiting for 10-15 min until the colloid is in a dry film state;

b. blanking a plurality of PVC plates 5 according to the size of a single template, sticking the PVC plates 5 from one side to the other side, and synchronously hammering the PVC plates by a rubber hammer to ensure that the PVC plates are firmly stuck without gas, thereby preventing the PVC plates 5 after sticking from swelling;

3) and mounting the bamboo chip plate 6:

a. processing the bamboo chip board 6: uniformly splitting the bamboo into three equal parts, performing press planing on the split bamboo strips by using a wood press planer, and finally performing press planing on all the bamboo strips uniformly to form the bamboo strips with the thickness of 35 mm;

the bamboo sheet plates 6 are made of moso bamboos or phyllostachys pubescens, the diameter of the bamboo outer opening of each bamboo sheet plate 6 is 10-14 cm, and the deviation of the diameters of the heads and the tails of single round bamboos is not more than 2 cm.

b. The bamboo strip plates 6 are connected: after a plurality of PVC plates 5 are laid, snapping lines on the surface of the plywood 4, marking the arrangement line of each bamboo chip plate 6, arranging and connecting the bamboo chip plates 6 according to the arrangement lines, reserving 35-45 mm spacing gaps between adjacent rows of bamboo chip plates 6, and exposing the PVC plates 5 in the spacing gaps;

c. fixing the bamboo strip plate 6: firstly, adhering double-sided adhesive tape on a section of a bamboo plate 6 on a PVC plate 5 for preliminary fixation, and then fixing the bamboo plate on a plywood 4 by nailing gun embedded nails, wherein nailing points are arranged on two edges of the bamboo plate, and nailing intervals are uniformly distributed;

the connection firmness of the bamboo strip plate 6 after being nailed can meet the use requirement, and the connection strength test can be carried out if necessary.

4) And processing gaps of the bamboo chip boards 6:

after the bamboo strip plate 6 is fixed, sealing the joint between the bamboo strip plate and the PVC plate 5 by using environment-friendly glue or cement gum to prevent slurry leakage during concrete pouring;

5) assembling the template:

a. rechecking a template control line on a base layer before template installation, and making a control elevation;

b. before the single template is assembled, a release agent is coated on the surface of the lining, and the template assembly is carried out according to the pre-assembly serial number, so that the perpendicularity of the splicing seams of the templates and the horizontal circle crossing of the cicada seams of the lining plates are ensured;

c. the two-sided assembled integrated template is erected relatively through hoisting, the lining with the bamboo chip plates 6 is guaranteed to be located on the inner side and is opposite to the inner side, the two-sided integrated template is penetrated through the at least one split screw 7, the two plugs 8 are sleeved in the middle of the split screw 7, the bolt holes in the integrated template are plugged through the plugs 8 to avoid slurry leakage, and the two opposite split screw 7 is worn out to be respectively sleeved with the clamp 9 and screwed down by uniform force application.

The stress of the adjacent counter-pulling screw rods 7 and the stress of the clamp 9 are ensured to be consistent by uniform force application, so that the template is prevented from being deformed unevenly. The reinforcing steel pipe hoop or the channel hoop must have sufficient strength and rigidity while being restricted from bending and deformation.

In the step 3) a, when the bamboo chip boards 6 are processed, the bamboo chip boards are cut at the middle points of adjacent bamboo joints, so that the shapes of the bamboo chip boards 6 are continuously consistent when the bamboo chip boards 6 are connected with the bamboo chip boards 6.

When the same row of bamboo strip plates 6 in the step 3) b are connected, a connection mode of a large-head joint to a large-head joint and a small-head joint to a small-head joint is adopted; the adjacent rows of bamboo chip boards 6 are arranged in a staggered mode in the large head arrangement direction and the small head arrangement direction.

Namely, the big end of the first row of bamboo chips 6 is left, the small end of the second row of bamboo chips 6 is left, and the big end and the small end are repeatedly arranged according to a big end and a small end, so as to avoid the alignment of the long-direction connection points of each row of bamboo chips 6, and the connection lines of the finished surface are less obvious through the staggered arrangement.

And 5) pre-splicing the templates on site before construction in the step 5), checking the surface flatness, the section size, the internal and external angles, the height difference of adjacent plate surfaces and the combined installation condition of the split screws 7 to ensure the quality of the templates, and numbering the back surfaces of the single templates according to the pre-splicing condition so as to meet the installation requirement.

In the step 5) b, when the integrated template is assembled, three seams of a template seam, a PVC (polyvinyl chloride) plate 5 seam and a vertical ridge joint seam are strictly forbidden to be combined into a whole, the three seams are staggered, and an aluminum beam is reinforced and is vertically arranged with the template seam; the vertical abutted seams and the vertical ridge joint seams of the adjacent single template are staggered, the vertical abutted seams and the vertical ridge joint seams are sealed by high-density sponge strips, the sponge strips are stuck to one side close to the template, and the sponge strips are forbidden to expose at one side of the lining plate; and (3) flattening the edges of the templates adjacent to the joints of the single templates by a manual plane, then pasting a double-sided adhesive tape, and splicing after the alignment is ensured.

utilize conventional 4 panels of plywood as the base plate, make interior lining material with PVC board 5 and arc bamboo slab, adopt metal square tube and channel-section steel as the load-bearing bone rib, adopt the composite forms system that traditional screw rod drawknot fixed mounting formed, it is convenient that preparation, installation are demolishd, and the construction speed is fast. 5 PVC plates are arranged between the bamboo chip plates 6 and matched with a release agent for use, so that the demolding is facilitated, and the appearance quality of concrete molding is ensured. The whole large formwork system is adopted, the on-site assembly of the formworks is reduced, the construction quality of the fair-faced concrete of the bamboo formwork veneer can be guaranteed, the decorative layer of a concrete structure can be eliminated, the material cost is low, the construction period is shortened, and the construction cost is saved.
