Abstract
The invention discloses a prestressed tension auxiliary construction stage device used for engineering such as railways, roads, industrial buildings, water conservation, energy and rock and soil anchorage. The prestressed tension auxiliary construction stage device comprises an outer formwork, an inner formwork, an anchor pedestal, a tensioning anchor and a pulley component, the outer formwork and the inner formwork consist of scaffold steel pipes, the inner formwork is placed in the outer formwork, the anchor pedestal is placed on the inner formwork, the tensioning anchor is placed on the anchor pedestal, the pulley component is connected onto the outer formwork, and universal rotating wheels are disposed at the bottom of the outer formwork. The anchor pedestal consists of square timber, a reinforcing mesh and reinforcing guardrails, the reinforcing mesh is placed on the square timer, and the reinforcing guardrails are placed on the reinforcing mesh. The prestressed tension auxiliary construction stage device is simple in structure and convenient to operate, and materials of the prestressed tension auxiliary construction stage device are available easily. In addition, engineering practices show that tensioning speed is fast, construction is safe, and construction expense is lowered after the novel stage device is used.
Description
Technical field
The invention belongs to field of engineering technology such as railway, highway, industrial construction, water conservancy, the energy and ground anchorage, be specially a kind of bench frame apparatus that adopts on-the-spot material, this bench frame apparatus is to use when assisting prestressed stretch-draw.
Background technology
Prestressing technique is through the engineering practice of decades and constantly research; Developed into the engineering of a comparative maturity; Its principle is widely used in the bridge engineering of railway and highway, the building construction of industry; And in the slope anchorage engineering of water conservancy and geotechnical engineering, have vast potential for future development and practical value.
Steel strand are applied the critical process that prestressing force is prestressing technique, so the quality control of prestressed stretch-draw, safety assurance, construction speed just seem particularly important.Generally, during prestressed stretch-draw, be to set up interim steel pipe scaffold construction at the stretch-draw position, remove the intact back of stretch-draw, and whipline carries out operation in case of necessity.Along with the large-area popularization of prestressing technique, this traditional scaffold can not satisfy the demand of construction speed and construction safety.When in high-speed railway, concentrating case beam prefabricated, set up scaffold stretch-draw and can not satisfy construction requirement, crane can not be assisted during the stretch-draw of Cast-in-Situ Continuous Beam serrated slot, and tension ground tackle promotes and in placely all needs to solve than problems such as difficulties; Simultaneously, during the heavy stretch-draw operation of, task tight in the duration, on-the-spot a large amount of constructors and plant equipment operation had simultaneously both caused the construction interference, influenced construction speed, also brought out security incident easily.
Summary of the invention
The objective of the invention is to overcome the weak point of existing tensioning construction framed bent, a kind of simple structure is provided, gathers materials on the spot, easy to operate, construction safety, prestressed stretch-draw auxiliary construction bench frame apparatus that construction cost is low.
Technical scheme of the present invention is: the present gantries device is made up of outer mould bases, interior mould bases, ground tackle pedestal, pulley assembly; Outer mould bases and interior mould bases are made up of scaffolding steel pipe; Internal mold is placed in the outer mould bases, and on the mould bases, tension ground tackle placed on the ground tackle pedestal in the ground tackle pedestal placed; Pulley assembly is connected on the outer mould bases, and outer mould bases bottom is provided with universal moving runner.
The ground tackle pedestal is made up of the lumps of wood, reinforced mesh and reinforcing bar guardrail, and reinforced mesh places on the lumps of wood, and the reinforcing bar guardrail places on the reinforced mesh.
Bench frame apparatus of the present invention can adopt on-the-spot material, simple structure, is convenient to operation, fast, the construction safety of tensioning speed, has saved material, manpower, device resource, has accelerated construction speed, effectively reduces the construction cost of production.

Among the figure, the universal moving runner of 1-, the outer mould bases of 2-, mould bases in the 3-, the 4-lumps of wood, 5-ground tackle pedestal, 6-reinforcing bar guardrail, 7-tension ground tackle, 8-pulley assembly, 9,10,11, the 12-scaffolding steel pipe, 13-jacking, 14-muscle net sheet, 15-steel plate.
The specific embodiment
Like Fig. 1, shown in Figure 2, present gantries device of the present invention is made up of outer mould bases 2, interior mould bases 3, ground tackle pedestal 5, tension ground tackle 7, pulley assembly 8; Outer mould bases 2 is connected to form by scaffolding steel pipe 9,10,11,12 with interior mould bases 3, and interior mould bases is connected with liftable jacking 13, and shown in Fig. 3, chart 4, assembling adopts scaffold clasp to connect; Interior mould bases 3 places in the outer mould bases 2, and the ground tackle pedestal puts 5 on interior mould bases 3, and tension ground tackle 7 places on the ground tackle pedestal 5, and pulley assembly 8 is connected on the outer mould bases, and outer mould bases 2 bottoms are provided with universal moving runner 1, and its connected mode is as shown in Figure 5.
The present invention can adopt on-the-spot scaffolding steel pipe and fastener set to dress up outer mould bases, and universal moving runner is installed at the bottom of the mould bases outside, the recycling of realization stand and mobile; Adopt on-the-spot scaffold tube, jacking and fastener assembling internal mold frame, be installed in interior mould bases in the outer mould bases, realize promoting and the interior mould bases of reduction, realize fine setting up and down through the jacking screw mandrel through the degree of tightness fastener; On the jacking of interior mould bases, lay the lumps of wood and reinforced mesh construction pedestal as tension ground tackle; On the stand top pulley is installed, is realized the fixing and mobile of tension ground tackle; If the stretch-draw place is spacious and comfortable, operator is had a surplus, and can not adorn interior mould bases, directly uses pulley to promote ground tackle.If the stretch-draw place is limited, when outer mould bases can not use, directly universal moving runner is installed and is used, but need anchor point to cooperate the up-down ground tackle with interior mould bases.
Can remove after the completion and be reduced to on-the-spot material, can also break assembling and have enough to meet the need use, practice thrift a large amount of expenses.After a steel Shu Zhangla of place accomplished, stand did not need to remove, and only needed 1 people that stand is moved to next stretch-draw position and can restart stretch-draw, had saved a large amount of scaffolds and had taken material and the manpower of tearing open; Ground tackle interior mould bases capable of using and pulley go up and down simultaneously, have reduced the cooperation of equipment such as crane; And, reduced the site operation interference because required site operation personnel is less.
