Abstract
The invention discloses a non-destructive removing method of a temporary support in continuous beam construction. A non-destructive removing structure comprises a temporary support, a jack, an upper wedge, a middle wedge and a lower wedge. The upper wedge, the middle wedge and the lower wedge are sequentially stacked between the temporary support and a continuous beam. A notch with an opening facing outwardly is formed between the upper wedge and the lower wedge. The middle wedge is inserted into the notch. An L-shaped steel plate which extends outwardly and bends downwardly is embedded in the middle wedge to form a counter-force seat. When the temporary support needs to be removed, the jack is mounted between the L-shaped steel plate and the temporary support, and the temporary support can be disconnected from the continuous beam by hoisting the jack. By the non-destructive removing method, the temporary support can be used repeatedly, social resource waste is reduced, no environmental pollution is caused, fast mounting and removing of the temporary support are achieved, construction efficiency is improved, industrialization of temporary supports is achieved, and average construction cost is lowered greatly.
Description
Technical field
The present invention relates generally to the construction of continuous beam utilization temporary support, relates in particular to a kind of harmless method for dismounting of temporary support being applied in Construction of continuous beam.
Background technology
In Construction of continuous beam, temporary support often adopts concrete or steel reinforced concrete integrated structure form, uses mechanical breaking or adopt the mode of acetylene cutting to remove in demolishing process, and demolishing process is that violence is removed, and temporary support is damaged, and can not have enough to meet the need use.At present, mainly there is following problem in traditional temporary support method for designing:
1, temporary support is disposable input, can not have enough to meet the need use, causes social resources waste, and pollutes local environment.
2, temporary support adopts concrete structure, when construction cost, takes a lot of work.
3, temporary support adopts concrete structure, after construction, must abolish, and indirectly increases construction cost.
Summary of the invention
The present invention seeks to for fear of the existing deficiency of above-mentioned prior art, a kind of harmless method for dismounting of temporary support being applied in Construction of continuous beam is provided, so that temporary support can have enough to meet the need use, convenient and quick construction, has reduced construction cost simultaneously.
The present invention is achieved by the following technical solutions:
The harmless dismounting structure of a kind of temporary support, includes temporary support, jack and upper, middle and lower wedge, it is characterized in that: temporary support adopts shaped steel assembly welding to form, and can have enough to meet the need use.Between described temporary support and continuous beam, be stacked with successively upper, middle and lower wedge, be formed with the breach of an outward opening between described upper and lower wedge, described middle wedge inserts in breach.Described upper, middle and lower wedge is concrete structure, and the upper and lower surface of the soffit of described upper wedge, the upper surface of lower wedge and middle wedge is respectively equipped with steel plate, reduces the frictional force between voussoir with this.
The L shaped steel plate that is embedded with protruding and downward bending in described middle wedge forms counter-force seat, and the bending end of described L shaped steel plate is welded with triangle stiffened panel, strengthens the non-deformability of L shaped steel plate with this.
When carrying out temporary support while removing, between the bending end of L shaped steel plate and temporary support sidewall, add jack.By jack, middle wedge is separated with upper and lower wedge, thereby make on the bearing of continuous beam whereabouts, and separate with temporary support.
Advantage of the present invention is:
1, in the present invention, temporary support can reuse, and reduces social resources waste, and does not pollute local environment;
2, the present invention has realized temporary support quick-assembling and dismounting, improves efficiency of construction;
3, the present invention has realized temporary support commercialization, greatly reduces the input of average construction cost.
Accompanying drawing explanation
Fig. 1 is side schematic view of the present invention;
Fig. 2 is demolishing process schematic diagram of the present invention;
Fig. 3 is the schematic top plan view of wedge in the present invention, L shaped steel plate and triangle stiffener.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of temporary support can't harm dismounting structure, includes temporary support 2, jack 9 and upper, middle and lower wedge 4,5,6, it is characterized in that: temporary support 2 adopts shaped steel assembly welding to form, and is directly installed on pier shaft 1.Between described temporary support 2 and continuous beam 3, be stacked with successively upper, middle and lower wedge 4,5,6, be formed with the breach 7 of an outward opening between described upper and lower wedge 4,6, described middle wedge 5 inserts in breach 7.Described upper, middle and lower wedge 4,5,6 is concrete structure, and the upper and lower surface of the soffit of described upper wedge 4, the upper surface of lower wedge 6 and middle wedge 5 is respectively equipped with steel plate 10, to reduce the frictional force between voussoir, and the separation between being convenient to.The L shaped steel plate 8 that is embedded with protruding and downward bending in described middle wedge 5 forms counter-force seat, and the bending end of described L shaped steel plate 8 is welded with triangle stiffened panel 11.When carrying out temporary support 2 while removing, between the bending end of L shaped steel plate 8 and temporary support 2 sidewalls, add jack 9.By jack 9, middle wedge 5 is separated with upper and lower wedge 4,6, thereby continuous beam 3 is separated with temporary support 2.
Claims (2)
1. the harmless dismounting structure of temporary support, include temporary support, jack and upper, middle and lower wedge, it is characterized in that: temporary support adopts shaped steel assembly welding to form, between described temporary support and continuous beam, be stacked with successively upper, middle and lower wedge, between described upper and lower wedge, be formed with the breach of an outward opening, described middle wedge inserts in breach; Described upper, middle and lower wedge is concrete structure, and the upper and lower surface of the soffit of described upper wedge, the upper surface of lower wedge and middle wedge is respectively equipped with steel plate; The L shaped steel plate that is embedded with protruding and downward bending in described middle wedge forms counter-force seat, and the bending end of described L shaped steel plate is welded with triangle stiffened panel.
2. the method for dismounting of the harmless dismounting structure of temporary support according to claim 1, it is characterized in that: in the time carrying out temporary support dismounting, between the bending end of L shaped steel plate and temporary support sidewall, add jack, pass through jack, middle wedge is separated with upper and lower wedge, thereby continuous beam is separated with temporary support.
