Description
Technical field
The utility model is related to a kind of late poured band and installs device, belongs to installing for architectural engineering late poured band
Apparatus field.
Background technology
When high-rise building design has annex, due to the load and stiffness difference of main building and annex it is larger, it will usually cause base
Plinth internal force and Foundation pressure are changed greatly, and excessive differential settlement occurs so as to cause basis.This relative settlement will cause
Larger shearing and moment of flexure, are likely to result under certain condition the even more big destruction of the cracking leak of base plate.
In order to solve the problems, such as settlement difference, movement joint or pouring after settlement are set generally between main building and annex.Typically
For, post-cast strip is referred in cast-in-place integral reinforced concrete structure, the provisional band shape seam only retained in construction period, is risen
To the effect of digestion sedimentation contraction distortion, according to requirement of engineering, after retaining certain hour, then become company with concreting is closely knit
Continue overall structure.
First, the setting of post-cast strip will increase construction workload, and higher requirement is it is also proposed to construction technology.Due to rear
Pour belt construction and be related to secondary operation, not only actually increase the complexity of construction technology, and influence whether to construct into
Degree, increase construction cost expense.
Secondly, with the fast development of national economy, building site an inch of land is an inch of gold, skyscraper is more and more more, and high level is built
During building foundation pit construction, in order to avoid Sand phenomenon during excavation of foundation pit, precipitation will be carried out, but thus be caused peripherally
Lower water level reduces causing adjacent building cracking, subsidence phenomenon to happen occasionally, and stops precipitation in advance and drop to a great extent
The probability that low above-mentioned accident occurs.
The problems such as deforming to solve the relative settlement between main structure body and podium, structure both shrinks deformation and temperature stress,
The mode of indwelling post-cast strip is used widely in architectural engineering.
At present, the device that installs of conventional architectural engineering late poured band mainly has plank sheathing formwork erection device, general
Logical expanded metal lath installs two kinds of device, and both modes deposit respective technological deficiency：
1）Plank sheathing installs device, is installed using plank, flitch steel pipe, inconvenient operation, high material consumption, and precision owes standard
Really, work consuming is time-consuming during form removal.
2）It is to install absolute altitude, position with reinforcing bar, expanded metal lath, steel pipe to be difficult to control to that ordinary steel expanded metals installs device, is especially existed
Mass defect is easily caused with post-cast strip steel plate water-stopping strip junction.
Chinese patent application CN201510032618.0 discloses a kind of post-cast strip exterior wall closure knot with elastic waterstop bar
Structure.It includes outer wall of basement, post-cast strip, wall outer side face, prefabricated cover plate；Described outer wall of basement, post-cast strip outside set
There is prefabricated cover plate, between outer wall of basement and prefabricated cover plate rubber fastening band is provided with；Horizontal steel is provided with inside described post-cast strip
Muscle, longitudinal reinforcement；Described preform lid intralamellar part sets cover plate embedded bar；Described outer wall of basement is with prefabricated cover plate by solid
Determine pull bar connection, and wall outer side face is bonding using waterproof mortar with prefabricated cover plate connection end portion.The patent easy construction, work
Low intensity, high working efficiency, and blocking-proof result is notable, impervious waterproof ability is strong.But patent position in construction is still difficult
To control, especially mass defect is still being easily caused with post-cast strip steel plate water-stopping strip junction.
Utility model content
The utility model aims to provide a kind of late poured band and installs device, and this installs device and can ensure that waterstop position
Put and late poured band size accurately, it is and not swollen mould, indeformable.
To achieve these goals, the technical scheme that the utility model is adopted is：
A kind of late poured band installs device, including be separately fixed at the first concrete body and the second concrete knot
The expanded metals in structure body end portion；Post-cast strip casting area is formed between first concrete body and the second concrete body；
It is structurally characterized in that, many tops are provided between the end of first concrete body and the end of the second concrete body
Bar, one end of every push rod is pressed closer in the end of the first concrete body, and the other end of the push rod is pressed closer in the second coagulation
The end of soil structured body；The end of first concrete body and the end of the second concrete body be embedded with to
A few waterstop, the waterstop is extending at least partially into the post-cast strip casting area；By extremely between adjacent two push rods
A few pull bar is fixedly linked.
Thus, expanded metals is fixed by push rod, then is strained and fixed connected two push rods with pull bar, thus, expanded metals, waterstop with
Concrete body pours integral, does not remove, it is ensured that the size of waterstop position and late poured band is accurate.
According to embodiment of the present utility model, further optimization can also be made to the utility model, below for optimization after
The technical scheme of formation：
Region is installed in order to increase, the end of the push rod and first concrete body or the second xoncrete structure
It is connected by bracketing between body.
Preferably, the waterstop is arranged between adjacent two bracketings.Thus, bracketing is clamped only under the pulling force of pull bar
Water band, it is ensured that the size of waterstop position and late poured band is accurate.
Preferably, two are provided between the end of first concrete body and the end of the second concrete body
Push rod.
Preferably, it is fixedly linked by two pull bars between adjacent two push rods.
Push rod length is adjusted for convenience, various sizes of post-cast strip is adapted to, and the push rod is length-adjustable adjustable
Push rod bolt.
Preferably, the pull bar is length-adjustable stay-bolt.
Preferably, the waterstop is steel plate water stopper.
For raising bonding strength, by pouring between first concrete body and the second concrete body
Build and be connected in the post-cast strip of post-cast strip casting area.Thus, expanded metals, waterstop and concrete body pour it is integral,
Do not remove.
By said structure, expanded metals of the present utility model, steel plate water stopper are not removed after installing, with concreting one
Rise.Bracketing is held out against with adjustable ejector rod screw rod and fix expanded metals, prevent casting and compacting of concrete effect from making expanded metals distending.Drawn with stay-bolt
Tight upper and lower two layers of adjustable ejector rod bolt, clamps steel plate water stopper, it is ensured that steel plate water stopper position and late poured band
Size is accurately, not swollen mould, indeformable.
Compared with prior art, the beneficial effects of the utility model are：The utility model guarantee steel plate water stopper position and
The size of post-cast strip accurately, has the advantages that not swollen mould, indeformable, easy to operate, low cost, safe and reliable, effect are good.
