Abstract
Provided is a method for erecting a form used for a spherical arch head cover. The concave surfaces of prefabricated blocks of a first circle face downward, and lower openings of the prefabricated blocks are attached to neat cement paste; at the same time, a steel bar hook is hooked on an upper opening of each prefabricated block, and lower foot rods of the steel bar hooks are tightly clamped in reserved steel bar hook holes; the prefabricated blocks of the first circle are sequentially installed; then prefabricated blocks of a second circle are installed, neat cement paste is cemented at the upper opening positions of the prefabricated blocks of the first circle, the concave surfaces of the prefabricated blocks of the second circle face downward as well, lower openings of the prefabricated blocks of the second circle are attached to the neat cement paste of the upper openings of the prefabricated blocks of the first circle, meanwhile, steel bar hooks are hooked on upper openings of the prefabricated blocks of the second circle, and lower foot rods of the steel bar hooks are tightly clamped in steel bar hook clamping grooves formed in the lower openings of the prefabricated blocks of the first circle; the prefabricated blocks of the second circle are sequentially installed; prefabricated blocks of other circles are spliced through the same method. The method has the advantages that no support is needed, meanwhile, the form is integrated with a cast-in-situ concrete layer, and the form does not need to be disassembled.
Description
Technical field
The present invention relates to spherical vault head construction mold method.
Background technology
At present; the general concrete cast-in-situ concrete method cast-in-place or the prefabricated component assembly unit that adopts of round building vault construction is carried out; above-mentioned job practices all must be built bow member below vault; the dress mould; template adopts wooden model or punching block mostly; need after construction is finished mould is removed, this mold method is complex process, cost height, long in time limit not only, and can't realize vault to the round building that big sky is striden.Therefore, be necessary to make improvements.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of spherical vault head construction to use mold method, have without any need for support, and mould is to form unitary whole with the Cast-in-place concrete layer, does not need characteristics such as form removal.
The present invention is achieved in that a kind of spherical vault head construction mold method, adopts following steps:
1) according to spherical vault head diameter and ratio of rise to span, calculates ball collar radius, sagitta, arch arc length, prefabricated height, the arch ring number of plies, prefabricated section thickness and width;
2) according to the data in the step 1), make prefabricated section, and the end opening end of prefabricated section is provided with reinforcing bar hook draw-in groove;
3) prefabricated section of different arch rings is numbered in order;
4) make the reinforcing bar hook;
5) at the cast-in-place collar tie beam in circle bay wall top, and carry out and step on the pin inclined-plane, simultaneously reserved steel bar hook eyelet;
6) beat plain-water slurry stepping on the pin incline position, with the prefabricated section concave surface of first lap down, and the end opening of prefabricated section is fitted on the plain-water slurry; Simultaneously reinforcing bar is hooked in the suitable for reading of prefabricated section, reinforcing bar hook foot lever down tightens at reserved steel bar hook hole intraocular; Order installs the prefabricated section of first lap successively;
7) second prefabricated section that encloses then is installed: the prefabricated section position of upper at first lap is beaten plain-water slurry, with the second same concave surface of prefabricated section that encloses down, and the end opening of prefabricated section is fitted on the prefabricated section of the first lap plain-water slurry suitable for reading, the prefabricated section that simultaneously reinforcing bar is hooked in second circle is suitable for reading, and reinforcing bar hook foot lever down tightens in the reinforcing bar hook draw-in groove of first lap prefabricated section end opening setting; Order installs the prefabricated section of second circle successively;
8) according to step 7), the prefabricated section of other arch rings is installed.
Its width of prefabricated section of installing when arch ring closes up can adopt equipment corrections such as cutting machine.
Whenever install an arch ring, calibration arch radius makes its error be no more than 5mm.
Compared with prior art, the mold method of spherical vault head of the present invention, without any need for support, and mould is to form unitary whole with the Cast-in-place concrete layer, does not need form removal.The invention has the beneficial effects as follows:
1, the Prefabricated block Mold Making is simple, expense is low, and is durable in use;
2, prefabricated section can be concentrated batch production production, but also field fabrication;
3, engineering construction is convenient and simple, and is safe and reliable;
4, save engineering cost, shorten the construction period.
