Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail 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 It is provided with two bracket parts 2.The bracket part of the present embodiment is connected with column by bolt.Two bracket parts are positioned at sustained height, And the opposite sides being distributed in column that two bracket parts are symmetrical.A horizontally disposed crossbeam it is respectively equipped with on two bracket parts 3.Crossbeam is positioned at above bracket part.It is bolted between crossbeam and bracket part.Crossbeam is made up of H profile steel, constitutes the H of crossbeam The wing plate of shaped steel is horizontally disposed with.Crossbeam on two bracket parts is parallel to each other.Any one end of each crossbeam is equal with the spacing of column Identical.
Being respectively arranged at two ends with one and hold out against limit component 4 of crossbeam.Hold out against limit component and be positioned at the top of crossbeam.Hold out against limit It is bolted between position component and crossbeam, specifically, holds out against limit component by bolt and the H profile steel constituting crossbeam Wing plate is connected.The end face holding out against limit component is provided with the upper limit plate 41 extended toward column direction.Upper limit plate and composition horizontal stroke The wing plate of the H profile steel of beam is parallel.Upper limit plate is provided with the bolt mounting holes running through the upper and lower surface of upper limit plate.
Building inner support list column joist system specifically used as follows:
As shown in Figure 3, Figure 4, it is erected on crossbeam between the shaped steel inner support 5 being made up of some shaped steel being arranged side by side.Column It is positioned at the middle part below shaped steel inner support for supporting crossbeam and shaped steel inner support.Shaped steel inner support is positioned at holding out against of crossbeam two ends Between limit component, upper limit plate is positioned between the top of shaped steel inner support, and upper limit plate and shaped steel inner support and can pass through Bolt connects, thus enhances building inner support list column joist system and the stability of shaped steel combination inner support.
Embodiment 2, remaining structure of the present embodiment is with reference to embodiment 1, and its difference is:
As it is shown in figure 5, a kind of inner support list column joist system of building also includes being set on column and can slide along column Body 6 is installed.The bracket part 2 of the present embodiment is arranged on installation body.Bracket part is welded as a whole with installing body.
As shown in Fig. 5, Fig. 6, Fig. 7, the lower surface installing body is provided with installation gap 8, the installation gap of the present embodiment It is two, and the opposite sides being distributed in column that two installation gaps are symmetrical.Unidirectional automatic fastening it is equipped with 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 72 and the telescopic resilience jacking mechanism 73 being arranged in installation gap.The surface of eccentric is provided 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 positioned at the lower section of eccentric.Telescopic resilience jacking mechanism includes being fixedly installed on installation set Vertical guide pin bushing 732 on body, can the vertical guide rod 733 being arranged in vertical guide pin bushing of up and down slideway and being arranged on vertical guide rod The roller 736 of end.Vertically the axis of guide rod is between horizontal rotating shaft and column.Vertically on the lateral surface of guide rod and be positioned at vertically Guide pin bushing be arranged over upper limit position block 735.Vertically on the lateral surface of guide rod and be positioned at the lower section of vertical guide pin bushing and be provided with lower position block 731.Vertically it is arranged with pretension compression spring 734 on the vertical guide rod between guide pin bushing and upper limit position block.Roller is resisted against eccentric Surface on.Eccentric is up pushed away by roller, makes eccentric up rotate around horizontal rotating shaft and be 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 level Axle.
Column top is provided with some column installing holes being equally spaced from top to bottom.Body is installed be provided with and column installing hole Corresponding body installing hole.
This programme can come holder for regulating seat piece and horizontal depth of beam by the height of regulation installation body, so that this enforcement The building inner support list column joist system of example goes for being supported the shaped steel inner support of various differing heights, specifically Operate as follows:
When moving on installing body and needing: operator directly can up move to required height by installing body.
When installing body and needing to move down: first, the lower end of the hand-held vertical guide rod of operator, by vertical guide rod toward drop-down, Roller is made to separate with eccentric.After roller separates with eccentric, eccentric down rotates around horizontal rotating shaft under Gravitative Loads, Eccentric is made to separate with column.Then, operator can move down into desired position by installing body along column.Followed by, behaviour Author discharges vertical guide rod.After operator discharges vertical guide rod, under the effect of pretension compression spring, roller will be against Up push away on the surface of eccentric and by eccentric, make eccentric up rotate around horizontal rotating shaft and be resisted against column lateral surface On.
Owing to the roller acting on vertical guide rod of pretension compression spring is by the surface being resisted against eccentric, make eccentric table Face abuts against on column;And owing to the surface of eccentric is provided with one layer of rubber antiskid layer, eccentric so can be avoided with vertical Produce between post and slide;Thus when installing the pressure that body is subject to down, the eccentric of unidirectional automatic fastening anti-shedding mechanism It is possible to prevent that body is installed to move down, and it is the biggest by pressure down to install body, then the clamping between eccentric and column Power is the biggest, thus ensures that installing body will not move down, and so installing body, bracket part and crossbeam just can support type reliably The vertical load of steel inner support.On the other hand, unidirectional automatic fastening anti-shedding mechanism can realize installing the step-less adjustment of body, And it is easy to adjust.
It addition, in order to be further ensured that the connection reliability installing body with column, it is also possible to by bolt, installation is overlapped Body is arranged on column, i.e. by bolt through body installing hole and corresponding column installing hole, is arranged on vertical by installation body (can need not the step for of installation body being arranged on column of course through bolt, directly by unidirectional the tightest on post Gu anti-shedding mechanism prevent install body move down both can).
