Abstract
The invention discloses the thin-walled square chest that a kind of closely knit construction method of cassette ceiling anti-floating and this method use, set in the middle part of thin-walled square chest through upper and lower through-hole, through-hole and closed case inner space seal off；When construction, first bottom muscle drawknot is mounted on the supporting element below template, then places thin-walled square chest, thin-walled square chest bottom and bottom muscle are subjected to drawknot；Zigzag shape lacing wire is placed between the central axis line of adjacent thin-walled square chest, and by drawknot at sinking in the middle part of zigzag shape lacing wire on the muscle of bottom, gluten is bound later, casting concrete in two times after gluten is bound is passed through using vibrating head when pouring every time and carries out vibration compacting in gap between adjacent thin-walled square chest and thin-walled square chest middle through-hole.The present invention not only ensure that the anti-floating effect of thin-walled square chest, but also can effectively prevent its lateral sliding, so that bottom of box concrete is more closely knit, can guarantee floor construction quality while largely saving steel and set-up time.
Description
Technical field
The invention belongs to pouring construction fields, are related to a kind of hollow floor construction technology, and in particular to a kind of cassette ceiling
The thin-walled square chest that the closely knit construction method of anti-floating and this method use.
Background technique
In the thin-walled square chest construction of hollow floor, since square chest itself is hollow design, when concreting, can be generated
Biggish buoyancy and lateral pressure, traditional method are to increase elongated anti-floating bar to fixed square chest on square chest top, and not only waste is big
The reinforcing bar of amount and artificial, it is also bad to the lateral displacement control effect of square chest.And since square chest area is larger, traditional handicraft without
Method is vibrated square chest bottom, and by periphery, vibrated concrete is difficult to fully flow into square chest bottom, and hole, and bottom are easy to appear after demoulding
The adaptation and intensity of portion's concrete not can guarantee yet, therefore are badly in need of the new construction technology of one kind and solve these problems.
Summary of the invention
It is an object of the present invention to provide the thin-walled sides that a kind of closely knit construction method of cassette ceiling anti-floating and this method use
Case stablizes thin-walled square chest installation, will not break away in casting process, in addition also make thin-walled
Square chest lower concrete pours more closely knit.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that：
A kind of closely knit working thin-walled square chest of cassette ceiling anti-floating, it is characterised in that：The thin-walled square chest transversal cross-section is
Regular polygon, longitudinal cross-section are isosceles trapezoid, collectively constitute a up big and down small closed case structure, the closed case structure
Middle part is set through upper and lower through-hole, and through-hole and closed case inner space seal off.
As an improvement, the thin-walled square chest is made of corrosion-resistant and light weight plastics, thin-walled square chest upper and lower surface difference
Equipped with symmetrical reinforcement slot.
As an improvement, the thin-walled square chest bottom is equipped with anti-floating lacing wire, anti-floating lacing wire is equipped with the mounting hole for drawknot.
As an improvement, the thin-walled square chest transversal cross-section is regular quadrangle or octagon.
A kind of closely knit construction method of cassette ceiling anti-floating, which is characterized in that include the following steps：
Step 1: bottom muscle install, above already installed template according to common process install bottom muscle, and by bottom muscle with
Supporting element below template carries out drawknot；
Step 2: placing thin-walled square chest, thin-walled square chest is uniformly placed on the muscle of bottom according to design position, and by thin-walled square chest
Bottom and bottom muscle carry out drawknot.
Step 3: making a few font lacing wires, by straight bar bending, the zigzag shape that the straight intermediate sinking in both ends is made is drawn
Muscle；
Step 4: placing zigzag shape lacing wire between the central axis line of adjacent thin-walled square chest, and by zigzag shape lacing wire
Drawknot is on the muscle of bottom at the sinking of middle part；
Step 5: binding gluten, after thin-walled square chest fixes, binds gluten above thin-walled square chest；
Step 6: concreting, after gluten is bound, concreting is carried out, it is logical using vibrating head in casting process
It crosses between adjacent thin-walled square chest and vibrates in gap and thin-walled square chest middle through-hole, so that concrete compaction.
As an improvement, when placing thin-walled square chest, two thin-walled square chest major parts can be offseted in step 2 and be superimposed fixation
It uses together.
As an improvement, when zigzag shape lacing wire is installed, can use the reinforcement slot in thin-walled square chest in step 4, it will be several
Font lacing wire is stuck in reinforcement slot and is formed to increase stability.
As an improvement, zigzag shape lacing wire is extend at the case face 1/3-1/2 of thin-walled square chest in step 4.
As an improvement, being used between the muscle of bottom at sinking in the middle part of supporting element below bottom muscle and template and zigzag shape lacing wire
Iron wire or Plastic Bandage drawknot.
As an improvement, being poured into for the first time not higher than thin-walled square chest height Step 6: concreting carries out in two times
It at 1/2, after initial set, then completes residual concrete and pours to smash, be poured for the second time, it is adjacent that two-step pouring utilizes vibrating head to pass through
It vibrates in gap and thin-walled square chest middle through-hole between thin-walled square chest, so that concrete compaction.
Present invention has the advantages that：
(1) more traditional thin-walled square chest is compared, increases among thin-walled square chest of the present invention and runs through through-hole, can allow vibrating head insertion side
Bottom portion vibrates, and effectively prevents generating cavity in the bottom of box, reinforces bottom of box concrete strength and adaptation, mention
The high construction quality of entire floor construction.
(2) traditional Anti-floating reinforcing steel bar need to waste a large amount of reinforcing bars and worker binds the time in the elongated arrangement in thin-walled square chest top；This
Invention utilizes zigzag shape lacing wire anti-floating, can save a large amount of reinforcing bar and worker binds point.
(3) conventional method anti-floating bar can only solve buoyancy on square chest top.But in concreting process and process of vibrating
In, there are biggish impact force and lateral pressure, square chest deviation is easily caused to cause the hidden danger of quality such as discontinuity.According to thin-walled
The zigzag shape lacing wire that square chest spacing processes in advance is mounted on square chest side, can effectively block square chest, reaches vertically and horizontally double
To fixation.
