Background technology
Concrete in the foundation ditch braced cuts system supports, encloses purlin and other temporary structures or reconstruction structure in demolishing process such as segmentation cutting, mechanical manual work cut; Conventional set up pin hand framed bent under the member waiting to remove; Avoid member in demolishing process, to meet accident dropping, dangerous situation such as inclination, but that this type of support body self is set up is comparatively loaded down with trivial details, notices that artificially node is more; Problem such as wayward safe mass not only; Simultaneously uneconomical again, wasted more material lease and manual work and set up operating cost, and the process of setting up takies the duration of a project.
Summary of the invention
The present invention will solve in the member demolishing process; Replace conventional safety leg hand framed bent; Adopt machine made steel member, be adapted to support member to be removed under the prerequisite of various height satisfied; Form the problem of a stable support system, a kind of scalable fixed support device when being used for concrete component and removing is provided.
Technical scheme of the present invention is: a kind of scalable fixed support device when being used for concrete component and removing; Comprise in length and breadth to load support, scalable vertical rod, in length and breadth to horizontal fixed bar, the spacing bearing of horizon bar, base; In length and breadth to load support be placed on wait remove to support below; Between load support and base, pass through scalable vertical rod support and connection in length and breadth, pass through between the adjacent scalable vertical rod to be fixedly connected to the spacing bearing of horizontal fixed bar and horizon bar in length and breadth.
The scalable vertical rod is made up of canned paragraph and telescopic section; Telescopic section places in the canned paragraph; And be connected with canned paragraph, have one group of spacing adjustment hole on canned paragraph and the telescopic section, be fixedly connected through the shearing resistance latch that inserts in the spacing adjustment hole between canned paragraph and the telescopic section.
The spacing bearing of horizon bar top has the groove that is used to place in length and breadth to horizontal fixed bar 4.
The canned paragraph of scalable vertical rod and telescopic section are 150mm * 150mm by the length of side respectively, and wall thickness is that the 8mm and the length of side are 130mm * 130mm, and wall thickness is that the square steel of 8mm is processed, and canned paragraph is connected with telescopic section at interval, every section 1m.
The invention has the beneficial effects as follows:
The present invention replaces conventional safety leg hand framed bent in the member demolishing process, adopt machine made steel member, is adapted to support member to be removed under the prerequisite of various height satisfied, can form a stable support system.
The present invention can carry out vertical adjusting through the scalable vertical rod according to execute-in-place environment and the height of being torn open member, this mode simple operation, and stress performance is reliable, and applicable scope is wide, and can reuse.

The specific embodiment
Like Fig. 1, shown in 2,3, a kind of scalable fixed support device when being used for concrete component and removing comprises in length and breadth to load support 2, scalable vertical rod 3, in length and breadth to the spacing bearing of horizontal fixed bar 4, horizon bar 5, base 7,
Be placed on to wait to remove to load support 2 in length and breadth and support below 1, between load support 2 and base 7, pass through scalable vertical rod 3 support and connection in length and breadth, pass through between the adjacent scalable vertical rod 3 to be fixedly connected to the spacing bearing 5 of horizontal fixed bar 4 and horizon bar in length and breadth.
(1) wait to remove support 1: before the dismounting, will support 1 and be positioned on the load support, and be close to carriage, and wait to remove support 1 weight and need be controlled between 1 ton to 8 tons, the bottom needs smooth, and global shape is the rectangle cylinder, and the cylinder aspect ratio is less than 5:1.
(2) in length and breadth to load support 2: [28 channel-section steels use high-strength bolt to be connected with scalable vertical rod 3.
(3) the scalable vertical rod 3: being made up of canned paragraph and telescopic section, is 150mm * 150mm by the length of side respectively, and wall thickness is that the 8mm and the length of side are 130mm * 130mm; Wall thickness is that the square steel of 8mm is processed; Two kinds of size intervals connect, and every section 1m is set, and less square steel inserts in the big square steel; And fix with the shearing resistance latch, insert in the spacing hole.
(4) in length and breadth to horizontal fixed bar 4: adopt [22 channel-section steels, the two ends fluting is shelved on the spacing bearing 5 of horizon bar;
(5) the spacing bearing 5:20mm of horizon bar steel plate, 200mm * 200m, the top recessing is in order to place in length and breadth to horizontal fixed bar 4;
(6) spacing adjustment hole 6: opening diameter 32mm, degree of depth 200mm is on setting and the scalable vertical rod 3; Use the high-strength shear-pin of diameter 30mm, two of sides, totally four of both sides; Staggered up and down the insertion is provided with, in the patchhole, in order to fixing, spacing, connection two ends vertical rod up and down.
(7) base 7:50mm is thick, 500mm * 500mm steel plate, and welding and scalable vertical rod 3 bottoms are in order to place the bottom unstability.
As shown in Figure 4; Work progress of the present invention: at first other are also transported outward more than garbage-cleaning with original place inner formword, steel pipe etc., and scattered carrier members is transported to the scene, before removing support, will carry out preparatory assembly unit to horizontal fixed bar, scalable vertical rod, the spacing bearing of horizon bar and base portion in length and breadth; The Support bracket that the form that adopts machinery and a dead lift to combine will be accomplished assembly unit is placed on to wait to remove and supports down; And adjust spacing adjustment hole according to being supported to structure floor (base plate) absolute altitude, carriage withstands it in length and breadth and supports the bottom surface to load support; After the adjustment of band absolute altitude finishes; The dismounting supporting member two ends cutting of adopting machinery to have been withstood by carriage is broken off, the band concrete cutting finish the back adopt the gas electric welding to cut off to support in reinforcing bar, adopt vertical transportation machineries such as mobile crane or tower crane to hang carriage and outward transport at last with the cutting supporting member that finishes; Adopt level to remove the Support Position to next subsequently, repeat the supporting removal process to Transport Machinery or a dead lift carriage.
