Description

The gang form that is used for construction of lift well

Technical field

The utility model relates to a kind of gang form that is used for construction of lift well, belongs to the construction formwork field.Be mainly used in the inner side template formwork construction of building construction of lift well.

Background technology

In the construction of elevator shaft template, adopt wooden form or combined steel template mostly, it is more loaded down with trivial details to construct; Holding time is long, needs material working tool a lot, and workman's amount of labour is big; Transport of materials stack and inconvenience, and material consumption is also bigger; Not economical rationality, and when construction safety of workers also be difficult to ensure, also can influence the duration sometimes.

Summary of the invention

For addressing the above problem, the utility model provides a kind of gang form that is used for construction of lift well.

The utility model is realized with following technical scheme: a kind of gang form that is used for construction of lift well; It comprises four symmetries master module, be connected the master module two ends the lengthening template, with the internal corner formwork that is connected of lengthening template, the extension bar of four symmetries that also comprise upending frame, are connected, be installed in the master module support that is used to support master module on the extension bar with upending frame; Described master module is made up of steel frame and the panel that is installed on the steel frame, steel frame is stupefied by last horizontal stroke, the limit perpendicular stupefied, in erect the horizontal stupefied rectangular frame of forming under stupefied, the crosspiece; It is triangle that described master module supports, stupefied with last horizontal stroke, the down horizontal stupefied integral body that is welded into, and last horizontal stroke is stupefied, horizontal angle between stupefied is 30 ° down--and 45 °; Master module supports with extension bar hinged; Described extension bar is a turnbuckle, and master module supports, all adopt between the upending frame and be articulated and connected; Described upending frame by cross up and down, be fixed on the suspension ring at cross top and be fixed on about between the cross center pillar form.

Its structural principle and method for using are: utilize rod member to be articulated and connected and rotate principle easily, the distance that can regulate template and metope is directly lifted by crane the last layer working face with tower crane.During operation, as long as the cross and the extension bar of upending frame placed the purpose that just can reach supporting template on the horizontal plane.When needing adjustment elevator shaft inner core to touch size, as long as the turnbuckle of adjustment extension bar just can achieve the goal.There is internal corner formwork at the inner corner trim position, when template size during greater than 1.8 meters, increases the lengthening template and can regulate size.

During form removal, as long as unclamp internal corner formwork version and lengthening template, with tower crane upending frame is sling, template and elevator shaft inner core concrete will be thrown off.

The beneficial effect of the utility model is: make things convenient for the installation and removal of elevator shaft template, and simple to operate, be convenient to rapid construction, economical and practical, and can be repeatedly used remarkable in economical benefits.

The specific embodiment

As shown in Figure 1, the gang form that is used for construction of lift well is made up of master module 1, master module support 2, extension bar 3, upending frame 4, lengthening template 5, internal corner formwork 6.Adopt fastener to connect between master module 1, lengthening template 5, the internal corner formwork 6.Master module 1 is made up of panel 1.1 and steel frame.Lengthening template 5 is measures of the lengthening template taked for the size that meets design requirement, and the lengthening template adopts combined steel formwork, and length is 3 meters.Width is respectively 100 millimeters, 150 millimeters, 200 millimeters, 300 millimeters several kinds, can be one during use, also can be polylith.Internal corner formwork 6 adopts the internal corner formwork of combined steel formwork, and width is 150 millimeters, and length is 3 meters.

As shown in Figure 2, steel frame is stupefied 1.2 by last horizontal stroke, the limit perpendicular stupefied 1.3, in perpendicular stupefied 1.4,1.5 times horizontal strokes of crosspiece stupefied 1.6 forms, master module is grown 3 meters, and is wide 1.5 meters.Panel 1.1 is processed by 1-1.5 millimeters thick steel plate, adopts between panel 1.1 and the steel frame to be welded to connect, or connects with self-tapping screw or rivet; Last horizontal stroke stupefied 1.2 with horizontal stupefied 1.6 be to process down with the square steel pipe of 1,5 meter of the length of side 30 millimeters long, and the limit perpendicular stupefied 1.3, in adopt between perpendicular stupefied 1.4 and be welded to connect, and can adopt between the template and be welded to connect, or with self-tapping screw or rivet connection; The perpendicular stupefied 1.3 steel plate bars by the 3-6 millimeters thick in limit are made, and long 3 meters of steel plate bar is wide 40 millimeters, and in the middle of 100 millimeters places apart from both ends and at interval 250-300 millimeter place is useful on the circular hole that is connected usefulness with fastener, 12 millimeters of diameters.In perpendicular stupefied 1.4 be to process with the square steel pipe of 1.5 meters of the length of side 30 millimeters long, and last horizontal stroke is stupefied 1.2, adopt between the horizontal stroke stupefied 1.6 down and be welded to connect.Crosspiece 1.5, spacing 500-600 millimeter, and the limit perpendicular stupefied 1.3, in adopts between perpendicular stupefied 1.4 and is welded to connect, when conflict with stupefied upper fastener connecting hole position, limit in the stupefied position of horizontal stroke, adjust the position of crosspiece.It is 30 millimeters the square steel pipe triangular support that is made by the length of side that master module supports 2, is welded into integral body with last horizontal stroke stupefied 1.2, down horizontal stupefied 1.6, and last horizontal stroke is stupefied 1.2, the angle between horizontal stupefied 1.6 is between 30 °-45 ° down; Between master module support 2 and the extension bar is hinged.

As shown in Figure 3, extension bar 3 is processed by turnbuckle, and master module supports 2, all adopt between the upending frame 4 and be articulated and connected.Upending frame 4 is made up of suspension ring 4.1, cross 4.2, center pillar 4.3; Suspension ring 4.1 are welded into annulus by the reinforcing bar of 30 millimeters of diameters, and internal radius is not less than 200 millimeters; Cross is welded by two long 300 millimeters No. 6 channel-section steels, and top cross 4.2 top center and suspension ring (4.1) are welded to connect; Be welded with the center pillar 4.3 that No. 6 channel-section steels are processed up and down between the cross 4.2.

During work, place horizontal level master module 1 to strut upending frame 4 and extension bar 3, the length of regulating extension bar 3 just can realize the interior cylinder size of elevator shaft of designing requirement.During the tube template formwork, also need internal corner formworks 6 to be installed in the elevator shaft,, between internal corner formwork 6 and master module, be provided with lengthening template 5 because cylinder size is had nothing in common with each other in the elevator shaft at four jiaos.Lengthening template 5 and master module 1, internal corner formwork 6 connect with fastener respectively.

Concrete curing is after the enough intensity during form removal; Earlier internal corner formwork 6 and lengthening template 5 fasteners are unclamped; With lifting appliance suspension ring 4.1 being sling, all is hinged because extension bar 3 supports 2 with upending frame 4 and master module, during lifting; Master module 1 will leave concrete surface, and template is moved on just can be as required.
