Abstract
The invention relates to a three-pole steel tube lapping fastener. The fastener consists of three single fasteners which are connected together in a shape of a 'straight line'. Each of the single fasteners comprises a fastener body with a circular arc-shaped notch and a circular arc-shaped clamping ring hinged with the fastener body. The circular arc of the clamping ring is opposite to the circular ring of the notch so that the pole steel tube is held between the clamping ring and the fastener body; one end of the clamping ring is hinged on the fastener body and the other end of the clamping ring is connected with a bolt on the fastener body by a nut; opening directions of various single fasteners are in a cross arrangement when the three single fasteners are connected in the shape of a 'straight line'. The fastener can distribute load on an upper part evenly on two poles on a lower part, which meets compulsory provisions of Technical Specification for Safety of Formworks in Building Construction JGJ162-2008, ensures strength, rigidity and stability of a steel tube formwork, and improves safety of the fastener-type steel tube formwork with adjustable height randomly.
Description
Technical field:
The present invention relates to pole steel tube lapping fastener in a kind of fastener type steel pipe falsework, specifically a kind of fastener of used pole steel tube lapping when setting up the fastener type steel pipe falsework belongs to the architectural engineering construction technique field.
Background technology:
Because the execution of " building operations template technical specification of security " JGJ162-2008, in the past in the construction of construction project, the mode of setting up of the general steel pipe falsework that is adopted, violated the compulsive clause of " building operations template technical specification of security ", shown in Figure 1, it adopts fastener that two vertical rods are overlapped, so that being formed, supports construction formwork, but, this overlapping mode forms the eccentric force of vertical rod, does not reach the axle center load of pole steel tube, and vertical rod rigidity is poor, influence the resistance to overturning and the safety in utilization of falsework, have potential safety hazard; Another kind of overlapping mode is as described below, it adopts fastener that two vertical rods are docking together and supports so that template is formed, but because the height difference of each building, therefore also there is very big-difference in the height of required falsework, and the distance between the vertical rod up and down of above-mentioned butt joint is non-adjustable, can only regulate the height of support by the mode of cutting hypomere steel pipe, but often not be suitable for next building site after steel pipe is cut again, increase construction cost, most of construction parties are unwilling to adopt.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of vertical rod lapping fastener of fastener type steel pipe falsework system, adopt this fastener can guarantee vertical rod uniaxial force load in the entire bracket system, to meet the compulsive clause of " building operations template technical specification of security ", thereby guarantee rigidity, intensity and the stability requirement of falsework, improve safety in utilization; And the height of support can arbitrarily be adjusted.
Technical solution problem of the present invention adopts following technical scheme:
A kind of 3 pole steel tube lapping fasteners, described fastener are " one " font by three unit fasteners and link together, and each unit fastener comprises:
Fastener body with circular arc recess, with a circular arc pressure ring that is articulated on the fastener body, the circular arc of described pressure ring is relative to the circular arc of described recess pole steel tube is held between pressure ring and the fastener body, one end of described pressure ring is hinged on the fastener body, and the other end of pressure ring is connected with bolt on the fastener body by nut; The opening direction of each unit fastener was staggered setting when described three unit fasteners were the connection of " one " font.
The design feature of fastener of the present invention also is:
Described fastener body and pressure ring are made by cast steel.
Described pressure ring is hinged on the fastener body by rivet.
Described bolt is a T type fastening bolt, and bolt and fastener body flexibly connect.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Fastener of the present invention can buckle the support of formation to template with three pole steel tubes that need overlap up and down, the top load can be uniformly distributed in two vertical rods in bottom, the compulsive clause that meets " building operations template technical specification of security " JGJ162-2008, intensity, rigidity and the stability of steel pipe falsework have been guaranteed, improved the safety of fastener type steel pipe falsework, and the height of support can be regulated arbitrarily.
Description of drawings:
The structural representation that Fig. 1 adopts fastener type to connect for existing vertical rod support, vertical rod eccentric force up and down.
Fig. 2 is the structural representation of fastener of the present invention.
Fig. 2 A is the upward view of Fig. 2.
Fig. 3 is the user mode figure of fastener of the present invention.
Number in the figure: 1 fastener body, 2 pressure rings, 3 rivets, 4 nuts, 5 bolts, 6 recesses, 7 leading screws, 8 connect steel pipes, 9,9 ', 9 " vertical rod, 10 horizontal steel tubes, 11 flitches, 12 typified forms, 13 unit fasteners.
Below pass through the specific embodiment, and the invention will be further described in conjunction with the accompanying drawings.
The specific embodiment,
Non-limiting examples is as described below:
Shown in embodiment: Fig. 2, the 2A, 3 pole steel tube lapping fasteners of present embodiment, this fastener can be considered by three unit fasteners be " one " font link together form, each unit fastener comprises:
Fastener body 1 with circular arc recess, with a circular arc pressure ring 2 that is articulated on the fastener body, the circular arc of described pressure ring is relative with the circular arc of described recess, pole steel tube is held between pressure ring and the fastener body, one end of pressure ring 2 is hinged on the fastener body 1 by rivet 3, the other end of pressure ring is connected with bolt 5 on the fastener body by nut 4, and bolt 5 is a T type fastening bolt, is connected with fastener body is active.Shown in Figure 3, three unit fasteners are the whole fastener that " one " font is joined together to form present embodiment, the opening direction of each unit fastener is staggered and is provided with, one end at bolt, nut place is the opening direction of each unit fastener, when nut 4 when bolt 5 unclamps, pressure ring 2 can rotate on fastener body 1 around rivet 3.
In concrete the enforcement, fastener body and pressure ring can be made by cast steel, nut and bolt can be made by carbon steel, during use, shown in Figure 3, the fastener that adopts present embodiment is with three vertical rods 9,9 ', 9 " snap together regularly; the vertical rod 9 that matrix is arranged is joined together to form template holder support to connect steel pipe 8; vertical rod 9 upper ends connect leading screw 7; fixedly connected unit, the upper end of leading screw 7 fastener 13; the unit fastener fastens horizontal steel tube 10 (promptly being commonly called as main stupefied or stupefied greatly) to support flitch 11 (be commonly called as time stupefied) and typified form 12; load that vertical rod 9 is born can be delivered to equably vertical rod 9 ' with vertical rod 9 " on, make vertical rod stressed evenly, load has rationally changed the situation of the steel pipe support for shuttering vertical rod eccentric force that generally uses at present, meets the Compulsory Feature of " building operations template technical specification of security ", guaranteed the intensity of steel pipe falsework, rigidity and stability have improved the safety of building operations operation, reliability.And vertical rod 9 and vertical rod 9 ' and vertical rod 9 " between distance can regulate arbitrarily, to satisfy different story height demands.
