Specific implementation mode
Present invention is further described in detail with specific implementation mode below in conjunction with the accompanying drawings:
Embodiment 1:As shown in Figure 1 and Figure 2, a kind of building inner support list column joist system includes a root post 1.Column Top is set there are two bracket part 2.The bracket part of the present embodiment is connected by bolt with column.Two bracket parts are located at same height Degree, and two bracket parts are symmetrically distributed in the opposite sides of column.Be respectively equipped on two bracket parts one it is horizontally disposed Crossbeam 3.Crossbeam is located above bracket part.It is bolted between crossbeam and bracket part.Crossbeam is made of H profile steel, is constituted horizontal The wing plate of the H profile steel of beam is horizontally disposed.Crossbeam on two bracket parts is mutually parallel.Between any one end and column of each crossbeam Away from all same.
The both ends of crossbeam are respectively equipped with one and hold out against limit component 4.Hold out against the top that limit component is located at crossbeam.Hold out against limit It is bolted between position component and crossbeam, specifically, holds out against limit component and pass through bolt and the H profile steel for constituting crossbeam Wing plate is connected.The top surface for holding out against limit component is equipped with the upper limit plate 41 extended toward column direction.Upper limit plate is horizontal with composition The wing plate of the H profile steel of beam is parallel.Upper limit plate, which is equipped with, runs through upper limit plate bolt mounting holes upper and lower surfaces of.
Build the specifically used as follows of inner support list column joist system:
As shown in Figure 3, Figure 4, it is erected on crossbeam between the shaped steel inner support 5 being made of several shaped steel arranged side by side. Column is located at the middle part below shaped steel inner support and is used to support crossbeam and shaped steel inner support.Shaped steel inner support is located at crossbeam both ends Between holding out against limit component, upper limit plate is located at the top of shaped steel inner support, and can be between upper limit plate and shaped steel inner support It is bolted, to enhance the stability of building inner support list column joist system and shaped steel combination inner support.
Embodiment 2, remaining structure reference embodiment 1 of the present embodiment, the difference is that:
As shown in figure 5, a kind of building inner support list column joist system further includes being set on column and being slided along column Dynamic installation body 6.The setting of bracket part 2 of the present embodiment is on installation body.Bracket part is welded as a whole with installation body.
As shown in Fig. 5, Fig. 6, Fig. 7, the lower face for installing body is equipped with installation gap 8, the installation gap of the present embodiment It it is two, and two installation gaps are symmetrically distributed in the opposite sides of column.Unidirectional automatic fastening is equipped in each installation gap Anti-shedding mechanism 7.Unidirectional automatic fastening anti-shedding mechanism includes being rotatably provided in installation gap by horizontal rotating shaft 71 Eccentric wheel 72 and the telescopic resilience jacking mechanism 73 being arranged in installation gap.The surface of eccentric wheel is equipped with one layer of rubber antiskid Layer.The thickness of rubber antiskid layer is 1 millimeter or 0.8 millimeter or 0.5 millimeter.
Telescopic resilience jacking mechanism is located at the lower section of eccentric wheel.Telescopic resilience jacking mechanism includes being fixed at installation set Vertical guide sleeve 732 on body, can up and down slideway the vertical guide rod 733 being arranged in vertical guide sleeve and be arranged on vertical guide rod The idler wheel 736 at end.The axis of vertical guide rod is between horizontal rotating shaft and column.On the lateral surface of vertical guide rod and positioned at vertical The top of guide sleeve is equipped with upper limit position block 735.It is equipped with lower position block on the lateral surface of vertical guide rod and positioned at the lower section of vertical guide sleeve 731.It is arranged on the vertical guide rod between guide sleeve and upper limit position block vertically and pre-tightens compressed spring 734.Idler wheel is resisted against eccentric wheel Surface on.Idler wheel up pushes away eccentric wheel, so that eccentric wheel is up rotated around horizontal rotating shaft and is resisted against on column lateral surface.Partially The surface of heart wheel is resisted against on column lateral surface.Contact position between eccentric surfaces and column lateral surface turns less than horizontal Axis.
Column top is equipped with several column mounting holes being equally spaced from top to bottom.Installation body is equipped with and column mounting holes Corresponding body mounting hole.
This programme can install the height of body come holder for regulating seat piece and horizontal depth of beam, to make this implementation by adjusting The building inner support list column joist system of example can be adapted for being supported the shaped steel inner support of various different heights, specifically Operation is as follows:
When installation body needs to move up:Installation body directly up can be moved to required height i.e. by operator It can.
When installation body needs to move down:First, operator holds the lower end of vertical guide rod, by vertical guide rod toward drop-down, Idler wheel is set to be detached with eccentric wheel.After idler wheel is detached with eccentric wheel, eccentric wheel rotates under Gravitative Loads around horizontal rotating shaft down, Eccentric wheel is set to be detached with column.Then, installation body can be moved down into desired position by operator along column.Followed by behaviour Author discharges vertical guide rod.After operator discharges vertical guide rod, under the action of pre-tightening compressed spring, idler wheel will be against It is up pushed away on the surface of eccentric wheel and by eccentric wheel, eccentric wheel is made up to be rotated around horizontal rotating shaft and is resisted against column lateral surface On.
Since the idler wheel for the vertical guide rod of effect for pre-tightening compressed spring will be resisted against on the surface of eccentric wheel, make eccentric wheel table Face abuts against on column;And since the surface of eccentric wheel is equipped with one layer of rubber antiskid layer, to avoid eccentric wheel and can stand in this way Sliding is generated between column;Thus when installing body by pressure down, the eccentric wheel of unidirectional automatic fastening anti-shedding mechanism It can prevent installation body from moving down, and install that body is bigger by pressure down, then the clamping between eccentric wheel and column Power is also bigger, will not be moved down to ensure to install body, installing body, bracket part and crossbeam in this way can reliable support type The vertical load of steel inner support.On the other hand, the step-less adjustment of installation body may be implemented in unidirectional automatic fastening anti-shedding mechanism, And it is easy to adjust.
In addition, in order to further ensure installing the connection reliability of body and column, it can also be by bolt by installation set Body is mounted on column, i.e., passes through body mounting hole and corresponding column mounting holes by bolt, installation body is mounted on vertical On column(Certainly it can not needed by bolt by the step for body is mounted on column is installed, directly by unidirectional automatic tight Both may be used Gu anti-shedding mechanism prevents installation body from moving down).
