The joint width of reserved joint pavement shall be in accordance with the design requirements.
4.
Sample setting: in principle, stones with high color saturation shall be used to ensure that they are consistent with the design tone of pavement.
During the pavement construction, tools (such as hanging line and cross flower) shall be used to assist in controlling the joint width, and the ruler difference shall not exceed 1mm; 3.
The water content of dry mortar is low, and the initial strength of mortar is relatively higher than that of ordinary cement mortar.
Material selection: the screening of materials before entering the site is an important measure to control from the source.
When it is unable to meet the application modulus of all plates, 45 ° butt joint or large and small plates can appear in hidden parts such as corners.
Trapezoid Rubber Magnetic Chamfer
Clean the joints and scrub the expansion joints after pointing.
1.
The specifications of large-scale paving plates shall be unified as far as possible to reduce the construction difficulty.
Control the color difference of materials as much as possible to ensure the quality of pavement.
The thickness of the mortar is generally about 3cm-5cm.
Fine sand or dry ash shall be used for joint sweeping, and the elevation of joint sweeping shall be controlled to ensure uniform appearance.
3.
when paving in a large area, the cross control line shall be pulled, and the spacing shall not be greater than 5m.
2.
Processing: control the cutting quality of stone materials, and directly return those with low quality and large color difference.
Proper modulus, half diagonal die opening, no typesetting (wrong) after typesetting, the edge and corner of the whole material track shall be free of broken (correct) 45 ° butt joint pavement treatment, careful typesetting (correct) no typesetting, poor (wrong) effect, standardized edge closing treatment (correct) typesetting is not optimized (wrong) adjustment position, symmetrical (correct) with the left side of the corner, and the seam width shall be controlled.
Recommended by the source manufacturer: 15837776657 sample plate can determine whether various materials are coordinated and unified through the trial laying of the sample plate, and clarify the specific construction technology, such as the specific requirements of the joint width, concave joint depth, joint pointing agent color, effect, etc.
The setting of the expansion joints must be reasonable and beautiful.
The upper and lower butt expansion joints of the expansion joints shall be set at the edge of the corrugated line.
Material selection 1.
The decorative pavement, corrugated line and structural layer shall be considered in a unified manner, and the source shall be reserved: Luban Alliance of construction engineering..
The mortar thickness of the bonding layer is determined according to the stone horizontal line.
During the pavement typesetting of important nodes, the setting out on the drawing shall be combined with the setting out on the spot.
The proportion of dry mortar for the pavement bonding layer shall be well controlled.
The jointing agent coordinated with the stone shall be used for jointing, and the elevation shall be consistent and flat; 4.

How to construct outdoor stone pavement? This paper comprehensively expounds the material selection, template making, construction process, typesetting and setting out, adhesive layer control, joint width control, pointing skills, finished product protection, typesetting control of important nodes and so on.
For stones with high quality requirements, special personnel must be arranged in the stone production area to screen, establish special supply channels, and buy out the same batch of materials from the manufacturer.
Keep the fabricated pavement template as long as possible so that all construction teams entering the site can understand the process requirements and quality requirements at the first time.
Paving: paving workers conduct on-site screening and sort out materials with low quality and large color difference.
The gap of sealing pavement shall not exceed 2mm, During the paving construction, tools (such as iron wire, metal sheet, etc.) are required to assist in controlling the joint width.
The water content must be strictly controlled, which is generally 7-9%.
When paving, the cement mortar of the bonding layer should not be paved too much at one time, and it should be paved at the same time.
(2) setting out and snapping lines: make accurate layout, snap elevation control lines on the surrounding walls, and snap typesetting lines on the base course (3) layout and pre paving (4) paving (5) pointing (6) finished product protection mortar and elevation control.
Construction process of template trial paving Garden Road template (1) cleaning the base course: avoid uneven surface of the base course, leaving mortar, lime soil, garbage, etc.
Before paving, the rough edge of stone shall be swept to reduce the dimensional error; 2.
Control the width of tight joints and openings through cross locators, small wood chips, bamboo chips, etc.
It is strictly prohibited to splash mortar before paving and pointing.
The dry mortar is generally based on taking up and holding the ball and leaving it for flowering.
Before stone paving, the elevation of concrete base course must be retested, The elevation and slope must be ensured to be accurate.
2.
Generally, the proportion of cement and sand is 1:3, the elevation control is wrong, the mortar is too thick (wrong) and the mortar is too dry (wrong) typesetting.
