Description
Technical field
The present invention relates to basement big bulk concrete constructing technical field, new formwork is cheated in particularly a kind of hole
System and its construction method.
Background technology
With gradually increasing for skyscraper, the application cheated in Large Concrete Base Plate, ultra-deep super large hole is increasingly
Frequently.The difficulty of construction at hole Zhong Keng positions is big, especially because traditional formwork system is unreasonable, easily cause hole bottom to float,
A series of problems, such as base plate concrete placings leakiness, percolating water being cheated in form bracing system inclination, hole, to ensureing basement bottom board,
Especially the construction quality of elevator and sump position base plate is extremely disadvantageous, and the construction quality problem at hole Zhong Keng positions is urgently solved
Certainly, it is very urgent.
Traditional construction method cheats planar dimension size, height in generally being cheated according to basement in the basement bottom board construction stage
Difference sets the box-shaped template of prefabricated overall back cover, used as the inside formwork at the hole such as elevator, sump Zhong Keng positions, concrete
Trickling to hole bottom is poured from case mould side, air-vent is reserved on bed die or case mould top ballast is used to prevent concrete placings process raising middle flask
The floating of mould, form removal after the completion of concrete placings.This construction method can trigger problems：Bottom absolute altitude is cheated in hole to be difficult to effectively
Control, or even there is case film floating, internal support structure is unstable, and hole bottom ponding, rubbish etc. cannot be cleared up, and base plate is cheated in hole and is poured
Leakiness is built, concrete strength is low, and impression quality is poor, so as to the hidden danger of quality and percolating water risk that cause the position serious.
Therefore, simultaneously its construction method of specification is particularly important for hole formwork system in improving traditional hole, thoroughly to prevent and disappear
Except the position hidden danger of quality.
The content of the invention
To overcome the shortcomings of that conventional construction method is present, cheat new formwork system in being cheated the invention provides one kind and its apply
Work method, efficiently solves and cheat in hole case film and float, cheat that the discrepancy in elevation is not enough in hole, cheating that bottom board concrete cannot be vibrated and receipts face etc. is asked in hole
Topic, not only ensure that elevator and sump construction of bottom plates quality, greatly reduce the quality such as the percolating water in position later stage hidden
Suffer from, meanwhile, hole support system construction technology in hole is simplified, optimize underplate concrete casting method.
To achieve the above object, the technical solution adopted by the present invention is：One kind cheats new formwork system in hole, mainly includes
Case mould and support, described case mould is the box template of upper opening, is made up of side template and end template, and described support includes
Longitudinal bracing and cross-brace, described end template are spliced by the bar template annular of 200mm ~ 300mm wide, form middle part
The hollow end template of opening.
Preferably, described end template is provided with the lumps of wood, and to strengthen the rigidity of end template, described side template is provided with perpendicular
It is inwardly stupefied and stupefied lateral out, the vertical interior stupefied use high-quality lumps of wood, lateral out stupefied use double steel pipe.
Preferably, described support is constituted using steel pipe support, and steel pipe support end is equipped with adjustable jack, when hole in hole
When the discrepancy in elevation or larger size, steel pipe post, enhancing case mould inside support resistance to overturning are set at middle part.
Preferably, described side template has the spacer bar of hole base plate in hole, to ensure the accurate positioning of case mould.
Preferably, triangle reinforcing plate is respectively provided with described case mould inside lock.
The present invention also provides the construction method that new formwork system is cheated in a kind of above-mentioned hole, mainly includes the following steps that：
Step one：Side template and end template are made, and is assembled into case mould, during making, according to the planar dimension and the discrepancy in elevation cheated in hole
Determine each piece of size of template, wherein, the bar template width needed for making end template is 200mm~300mm, after completing assembly
Form the hollow end template of intermediate openings；
Step 2：Case mould is installed, is completed and after concealment acceptance after reinforcing bar colligation is cheated in basement bottom board and position hole, hole is set
Middle hole side wall and base plate spacer bar, case mould is installed in the position according to spacer bar；
Step 3：Support is set, by the interval setting longitudinal bracing and cross-brace of 800mm~1000mm, it is ensured that concrete is poured
When building workman can descend to hole bottom carry out operation, be conducive to concrete effectively vibrate and receipts face work carrying out, support two ends
Adjustable jack is respectively provided with, when cheating planar dimension in hole and being larger, steel pipe post enhancing support system monolithic stability is set at middle part
Property；
Step 4：Casting concrete, placement layer by layer hole Zhong Keng positions concrete, when the height to end template is poured, bar shaped mould
Plate can effectively prevent concrete from running in cartonning mould, and the hollow end template of intermediate openings can avoid floating or the inclination of case mould, no
Only ensure the elevation of bottom cheated in hole, more improve the pouring quality cheated in hole.
Further, in step 4, after the completion of concreting, workman is shaken by being inserted at the intermediate openings on end template
Tamper vibrates to concrete, and carries out the work of receipts face to hole base concrete, is greatly improved the construction of hole concrete in hole
Quality and perception effect.
The beneficial effects of the invention are as follows：New formwork system and its construction method are cheated in a kind of hole that the present invention is provided, is led to
The intermediate openings measure for crossing end template efficiently solves the problems, such as that case mould floats during concreting, eliminates to prevent on case mould
The measure that top sets ballast is floated over, the opening on end template can also in time clear up the rubbish and ponding at hole Zhong Keng positions, and be
Observation hole bottom condition of construction is provided convenience, the positioning bar that side template bottom is set, and can accurately control to cheat base plate in hole
Absolute altitude, supporting base end portion set adjustable jack, can flexibly be adjusted in concreting process hole in cheat side wall deviation,
Ensure planar dimension and the side wall flatness cheated in hole, meanwhile, optimized by supporting, facilitate in being cheated to hole bottom under workman
Cheat concrete vibrating and the work of the face of receipts of base plate, it is ensured that the packing of bottom board concrete is cheated in hole, greatly reduces later stage basement bottom board
Percolating water hidden danger, the construction quality of the deep position that falls such as hole effectively in lifting hole, formwork system of the invention construction is simple, operation
It is easy, safe and reliable, and repeatable utilization, it is economic and environment-friendly.
