Abstract
The invention discloses a formwork support for a cast-in-place concrete plate and relates to formwork engineering of concrete plates. The construction workload of a support system is reduced by adopting a matching tool type bent frame system taking a hybrid structure convenient to assemble in site and locally disassemble as a main framework as the formwork support, hinging combined parts of the hybrid structure by utilizing pre-stress by virtue of a connection structure of a semi-hinge groove, a fixed hinge shaft and a movable sleeve, finely adjusting the lifting of a main structure by using a mechanism frame foundation and adopting the application of strong-stiffness and high-strength support of the hybrid structure to a strong-stiffness large edge. The formwork support is simple in structure, simple and convenient in construction and capable of improving the supporting effect, greatly shortening the operation hour and the time limit of a subentry project and reducing the usage amount of a member material. The formwork support supports local support and early removal of a formwork, and the turnover rates of the formwork and a supporting member are increased. The working reliability of the support system is high, and the fine adjustment for the lifting of the main structure, realized by using the frame foundation, is simple in operation and precise in size, so that the construction quality and safety are ensured.
Description
Technical field
The present invention relates to a kind of constructive engineering template support.
Background technology
The shuttering supporting that architectural engineering at present includes the cast in place concrete plate such as floor, the top board of structures, landing slab is normal
Using full hall steel pipe scaffold system, construct in the way of single rod member dissipates spelling, its assembled and fastening support method is：Use foot
Hand cradle steel pipe and the fastener matching are assembled into full hall scaffold, reserve regulation space on scaffold upright rod top, use leading screw top
Support adjusts concrete slab template height stupefied greatly and flatness.
There are the following problems for this conventional support system：
1. the section mechanical property directly bearing the vertical rod of vertical load is weaker, and the layout density of vertical rod is higher, Er Qiexu
With more than vertical rod quantity horizon bar in length and breadth and diagonal brace fastener forms monolithic stability and vertical rod single pole meets pressure bar stabilization condition

Relative displacement is made and crane seat height degree along its hypotenuse in the top and the bottom of stand, and control plane rigid frame lifts；With scaffolding steel pipe and
Fastener is connected as longitudinal rod and diagonal brace with the linkage connector of the lateral surface at limb post upper, middle and lower position, and longitudinal rod doubles as foot handss
Frame horizon bar, in back timber holder wedging wedge tool, the straight flange of wedge tool is parallel with the stupefied greatly side wall being overlapped on back timber, hypotenuse and holder
Oblique plate parallel contact, each stupefied greatly wedge that each adjacent plane rigid frame is made of wedging connects, by wedging stupefied greatly as bent structure
Top longitudinal rod, constitutes framed bent spatial stability system；The fixing hinge of the external section of back timber of external truss takes seat in back timber half
Hinge notch, the fixing hinge jacking of upper strut cuts with scissors notch in the external section of back timber half, and the fixing hinge tip cutting of lower supporting rod is in limb post
The limb post in portion partly cuts with scissors notch, and the fixing hinge lodge of the pull bar sleeve in limb post middle and upper part partly cuts with scissors notch, between upper lower supporting rod
Angle above this two bar is less than π, between the wedge wedging trapezoidal backing plate of limb post and moving sleeve, the hypotenuse of wedge down with
The hypotenuse of trapezoidal backing plate is parallel to be held out against, and straight flange is parallel with the lower straight flange of movable sleeving barrel to be held out against, tight by the jacking of moving sleeve
Gu the prestressing force applying realizes the fixing hinge of pull bar and sleeve partly cut with scissors groove, the fixing hinge of lower supporting rod and limb post partly cut with scissors groove, on
Hinge between the fixing hinge of strut and the external section of back timber half hinge groove, the fixing hinge of the external section of back timber and back timber half hinge groove is even
Connect, constitute the plane stability system of plane rigid frame and external truss；Back timber external section holder wedging wedge tool, with back timber holder
Identical mode wedge connects each adjacent external truss and overlap joint stupefied greatly, the horizontal direct selling insertion lower supporting rod of side stay thereon
Laterally attached plate pin-and-hole, the other end of side stay is connected triangularity, structure with fastener with the longitudinal rod in the middle part of limb post
Become external truss spatial stability system；Pine moves back back timber external section holder wedge tool successively, the fastener of side stay, limb post move
Wedge under sleeve, deconstructs external truss, and the morning realizing external truss support segment template tears open；Pine moves back back timber holder wedge successively
Have, dismantle longitudinal rod and diagonal brace, given up the throne with the carry leading screw that crank shakes stand, the pressure of pine oil plane rigid frame, destructing
Support system.
2. the shuttering supporting of cast in place concrete plate according to claim 1, is characterized in that：The deformation structure bag of external truss
Include：The angle above this two bar between upper lower supporting rod is more than π, and pull bar is changed into depression bar, the trapezoidal backing plate of corresponding limb post and
The above-below direction of moving sleeve setting is made reversely to change, and trapezoidal backing plate is placed in above moving sleeve, and down, sleeve partly cuts with scissors groove to hypotenuse
Notch down, the fixing hinge jacking of depression bar partly cuts with scissors notch in sleeve, and other components of external truss are constant；Wedging wedge,
Realize the chain connection of external truss each component node by the prestressing force that the top fall fastening of moving sleeve applies.
3. the shuttering supporting of cast in place concrete plate according to claim 1, is characterized in that：Stand mechanism can also independently answer
For include individual struts, joist, bracket, plant bottom case other bear the component of gravity laod or the bearing lifting of base is micro-
Adjust.
