Abstract
The invention relates to a cavity mold template for carrying out anchor seal to unbonded prestressed end portions, which is characterized in that a template body is in a hopper shape with a big top and a small bottom, an upper opening and the lower bottom surface are both quadrate, and a bundled bar through hole is arranged in the middle of the lower bottom surface. The diameter of the bundled bar through hole is 90mm to 150mm. The cavity mold template is precast in a wall-supporting column when a slip form is constructed on the silo wall to carry out the anchor seal to the end portions of a pilaster of the unbonded prestressed silo wall. Compared with a traditional construction technology, the cavity mold template reduces construction processes and has no need to bind reinforcing ribs and erect and remove templates for sealing positions on the side face of the pilaster. Concrete is directly used for sealing the cavity mold reserved in the slip form construction, thereby being high in construction quality, simple in process, convenient in construction, short in construction period and capable of guaranteeing construction safety. The cavity mold template for carrying out the anchor seal to the unbonded prestressed end portions has simple structure, low cost and strong operability.
Description
Technical field
The present invention relates to sealing off and covering anchorage cave, a kind of prestressing without bondn end mould template.
Technical background
Present most of major diameter silo bulkhead adopts the prestressed concrete construction technology; Buttress unbonded prestressing tendon plug at end part adopts the construction of secondary formwork monobloc cast; To prop up the form removal construction to the reinforcing rib and the high-altitude at colligation shutoff position, pilaster side at every turn; Not only how very loaded down with trivial details again operation is, and cause the outward appearance impression poor, and speed of application is slow, workmanship is poor.
Content of the present invention
The present invention seeks to existing problem, provide a kind of not only construction quality high, and avoid the required formwork of buttress construction sealing off and covering anchorage, formwork reinforcement operation to people; Operation is few; Duration is short, and speed of application is safety again soon, sealing off and covering anchorage cave, the prestressing without bondn end mould template of economical with materials.
The present invention is characterized in that: described template plate body is up big and down small infundibulate, and suitable for reading and bottom surface is square, has tendon perforation in the middle of the bottom surface.
The tendon perforation is directly through being 90～150mm.
Effect of the present invention
Pre-buried cave mould template in buttress when 1, the present invention is employed in the bulkhead sliding formwork; Sealing off and covering anchorage is carried out in non-bonded prestressed silo bulkhead structure pilaster end; Compare with traditional construction technology; Reduced working procedure, need not, prop up form removal the reinforcing rib and the high-altitude at colligation shutoff position, pilaster side as traditional construction technology.It is in the cave mould of in slding form operation, reserving, direct blocking concrete, and therefore not only construction quality is high, and operation is simple, easy construction, duration are short, and has guaranteed the safety of construction.
2, the present invention is simple in structure, and is with low cost, workable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is user mode figure of the present invention.
The specific embodiment
Embodiment 1:
Referring to Fig. 1～2, template plate body 1 of the present invention is up big and down small infundibulate, and suitable for reading 2 are square with bottom surface 3, have tendon perforation 4 in the middle of the bottom surface.The tendon perforation is directly through being 90～150mm.
During the bulkhead slding form operation, pre-buried cave, both sides mould template outside buttress makes presstressed reinforcing steel bundle 5 pass spiral bar 6, paste tight presstressed reinforcing steel anchor plate 7 with exterior sheathing, passes and has tendon perforation and ground tackle 8 under the mould template of cave in the middle of the bottom surface.In time remove cave mould template after the bulkhead sliding formwork rises, note finished product protection during stripping.
Claims (2)
1. sealing off and covering anchorage cave, prestressing without bondn end mould template, it is characterized in that: described template plate body is up big and down small infundibulate, suitable for readingly is square with bottom surface, has tendon perforation in the middle of the bottom surface.
2. sealing off and covering anchorage cave, prestressing without bondn according to claim 1 end mould template is characterized in that: tendon is bored a hole directly through being 90～150mm.
