Description

A kind of self-insulating light wallboard system and installation method
Technical field:
The invention belongs to technical field of building construction, particularly to a kind of self-insulating light wallboard system and installation method.
Background technology:
The light aggregate concrete self-insulating light wallboard of high-strength light, as the novel wall material that country advocates energetically, popularization and application widely should be obtained, but the application of China's current light aggregate concrete self-insulating light wallboard is unsatisfactory, for now, use only accounts for about the 3% of materials for wall total amount.With regard to its reason, mainly self-insulating light wallboard self easily cracks and dry shrinkage brings T and G joint place between wallboard and wallboard also easily to crack, and wallboard and beam-to-column joint place also easily produce crack etc..This is primarily due to existing wallboard and mostly there is following shortcoming: tenon tongue-and-groove form, present wallboard is typically all the tenon tongue-and-groove connected mode adopting concave-convex, body of wall fore-and-aft direction can only be played Stabilization and be easily installed construction by this connected mode, and to there is no pulling force between wallboard;Wallboard adhesive mortar, in order to make wallboard joints place not ftracture, generally use glue and become adhesive mortar with Portland cement mix, but extraneous temperature and humidity change causing expand with heat and contract with cold and self-insulating light wallboard self is dry shrink time, wallboard joints place still can be caused to crack or crack, simultaneously two kinds of composition respectively inorganic material of adhesive mortar and organic material, both are incompatible, time one length will be separated from each other, and adhesive property is substantially reduced, thus causing that crack produces;Mounting technique, install and lack of standardization cause body of wall that another major reason of crackle occurs, the feature of wallboard product is not known about by workmen, mounting process is understood not in place, or for figure easy construction, change construction procedure without authorization, such as there is no the ratio consumption of mortar composition and regulation on request, T and G joint place mortar tamps not full, thus causing the generation that wallboard joints place ftractures, body of wall curing period, does not arrive premature removal timber wedge or body of wall is carried out next step operation after installation is complete simultaneously, as pipeline is slotted, finishing etc., body of wall can there be is direct impact damage, this is also the major reason causing wall crazing.
Summary of the invention:
The present invention is directed to the deficiency that prior art exists, it is provided that a kind of self-insulating light wallboard system and installation method, solve the cracking phenomena occurred after wallboard is installed well.
A kind of self-insulating light wallboard system provided by the present invention includes self-insulating light wallboard, drawknot screw, long nut, expansion bolt, corner brace, bar spacer, special adhesive mortar, grouting material, rubber cushion blocks, timber wedge and frame structure, the position from floor slab tops 120~250mm, the described self-insulating light wallboard upper end is provided with the through hole of horizontal direction, upwards position, the centre of described through hole is provided with grout hole, described self-insulating light wallboard side is the tongue-and-groove of depression, and the opposite side of described self-insulating light wallboard is the tenon protruded.
The installation method of self-insulating light wallboard system of the present invention specifically comprises the following steps that
(1) prepare first block of wallboard is installed: the correspondence position on the both sides of described frame structure Yu described through hole squeezes into expansion bolt respectively, all remove the nut of first wife, change described long nut by installing first piece of self-insulating light wallboard expansion bolt over there and tighten.
(2) first piece of self-insulating light wallboard is installed: hold up first piece of self-insulating light wallboard, four pieces of timber wedge location are squeezed into levelling below first piece of self-insulating light wallboard, timber wedge makes first piece of rubber cushion blocks between self-insulating light wallboard and frame structure hold out against, ensure that the expansion bolt in left side is consistent with the position of through hole simultaneously, at first piece of self-insulating light wallboard lower end right flank, corner brace is installed, is fixed by nailing gun nailing.
(3) drawknot screw is installed: bar spacer on the position card of the 1/5~1/6 of described drawknot screw two ends, stretches into described through hole, find the position of long nut accurately and tighten, and screw on described long nut at the right-hand member of described drawknot screw.
(4) second piece to second from the bottom piece self-insulating light wallboard is installed: smear special adhesive mortar at the tongue-and-groove place of first piece of self-insulating light wallboard, then second piece of self-insulating light wallboard is holded up, tenon is directed at tongue-and-groove and slowly squeezes out special adhesive mortar, position levelling with four pieces of timber wedges again and described corner brace and drawknot screw are installed, being repeated in second piece to second from the bottom piece self-insulating light wallboard is installed.
(5) last block self-insulating light wallboard is installed: after second from the bottom piece of self-insulating light wallboard installs, described drawknot screw is filled in the described through hole of last block self-insulating light wallboard, special adhesive mortar is smeared at the tongue-and-groove place of second from the bottom piece of self-insulating light wallboard, hold up and fix last block self-insulating light wallboard, then find described drawknot screw the position of long nut accurately and tighten, finally described drawknot screw being connected by welding manner with the described expansion bolt on right side.
(6) after whole self-insulating light wallboard installs, the degree of plainness for wall surface of correction self-insulating light wallboard, after stitching special adhesive mortar final set Deng plate, grouting material is poured in grout hole, then between self-insulating light wallboard and beam slab, floor, tamp special adhesive mortar, finally carry out laying anticracking paper tape, glass fiber net between mortar closing in and self-insulating light wallboard, smearing adhesive mortar.
(7) after self-insulating light wallboard installs, must not collide within 24h, next process must not be carried out, the body of wall of self-insulating light wallboard should be taked safeguard procedures, any lateral force must not be born in 7 days, construction ladder, engineering material must not support, push up pressure or lean against on self-insulating light wallboard, after 3 days, bottom self-insulating light wallboard, special adhesive mortar intensity withdraws from timber wedge when reaching more than 5MPa, and the cavity stayed by timber wedge with special adhesive mortar is tamped.
