Template installation procedure and requirements
(1) In order to prevent slurry from leaking from the lower opening of the template, before the side die is installed, the bottom die is kept horizontal, and a sponge strip 401 is glued on the top surface of the bottom die at the position where the template is located, so that slurry leakage is reduced; for the template with the suspended bottom, before the template is installed, a template bearing strip or belt (such as a pylon, a double-row frame, a batten and the like) needs to be arranged and is straightened.
(2) When the side die is hoisted, a professional signaler and a professional hitching worker are needed to finish the hoisting operation.
(3) The side die hoisting must be performed with targeted safety technology, and the construction operators must perform signature procedures.
(4) When the side mold is hoisted, the side mold needs to be vertically hoisted, stably hoisted and stably dropped and strictly prohibited to swing to a large extent, and before hoisting, whether the template and the surrounding bag are scraped or not needs to be checked; after unhooking, the tower lifting hook and the steel wire rope must exceed the guardrail of the template platform frame and a rotatable arm behind other obstacles; the ground operator must leave the formwork 2m away when the formwork is lifted.
(5) And after the template is qualified, concrete should be poured in time to prevent the building template from deforming after being exposed to the sun for a long time.
Die assembly casting concrete
(1) The panel is cleaned before the mold is closed, the cleaning panel is preferably brushed by a brush with medium hardness, the panel surface needs to be wiped clean, otherwise, dust on the template can be stained on the surface of the concrete, and the working procedure needs to be ensured to be carried out after the concrete is brushed.
(2) After the stencil is dried, the surface of the stencil is brushed with a release agent (salad oil) using a brush or a clean towel. The paint should not be brushed too much, and the paint should not flow, and should have gloss but no oil mark. Ensuring uniformity and brushing once again after rain.
(3) And (5) checking whether the steel bars conflict with the template pull rod hole and the embedded part system, and adjusting the positions of the steel bars if the steel bars conflict with the template pull rod hole and the embedded part system.
(4) According to the construction measuring point, the positioning support for controlling the space between the templates on the steel bar is firmly welded, and the inner support is made by adding concrete protective layers on two sides of the steel bar.
(5) And (5) mold closing correction. The template edge is corrected for the verticality of the template by an instrument or a line weight, and the angles of the male and female angle templates are adjusted by an angle square to ensure that the verticality and the angles meet the design requirements. Then the sleeve and the pull rod are penetrated, and the nut is screwed. And (5) rechecking the template and adjusting to meet the requirement of casting concrete. Note that the sleeve should not be too long, and preferably extends 20mm beyond the back of the form.
The cautions in the concrete pouring process are as follows:
a. the blanking is uniform and continuous, and the jamming caused by centralized and violent throwing is avoided. The inserted vibrator can be started to assist blanking in a short time at the dense part of the reinforcing steel bar and the pore channel.
b. The concrete mixing quality is checked at any time during the pouring process, and the water cement ratio is strictly controlled to ensure the concrete quality.
Requirement for demolition of formwork
(1) And when the strength of the concrete meets the quality requirement, the form can be removed. When the mold is disassembled, the pull rod nut is disassembled, the pull rod is pulled out, and the pull rod nut is stacked at a proper position. And unloading the core belt, and moving or hanging away the template.
(2) Firstly, the abutted seam template is dismantled, then the arc template is dismantled, and the template is strictly forbidden to be hammered by a sledge hammer or to be pried by a crowbar so as to avoid damaging the surface of the concrete.
(3) And (4) stacking, cleaning and repairing the templates. After the template is dismantled, the board surface and the gap of the template are completely and thoroughly cleaned immediately, and the phenomenon of sticking the template is avoided in the next use. After the template is used, maintenance and cleaning such as template cleaning, deformation correction, template accessory replacement and the like are carried out.
(4) In the process of hoisting the templates, each template needs to be placed on a batten to be stably lifted and stably fallen.
(5) Non-template operators must not enter the template work area at will and must wear safety protection articles. The operation against the regulation and the command against the regulation are not required to be followed by the command of the operation group leader.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
