The utility model discloses a I-steel encircles and encloses as supporting, need not to increase other members, utilizes the radial pressurized of circle of encircleing to reach stable in structure, and the dismouting is simple, and the location is accurate, and the structure is reliable, can practice thrift the cost, but reuse is applicable to the construction of small cross section shaft lining.
Description
Technical Field
The utility model relates to a strutting arrangement specifically is a small cross section shaft lining cutting strutting arrangement.
Background
The vertical shaft is generally tunneled from top to bottom, after a preset section of excavation height is excavated, lining concrete is constructed from bottom to top, single-row tunneling and lining operation is carried out, and excavation and lining are alternately carried out. The forms for lining generally include fabricated metal forms, integrally movable metal forms, and hydraulically liftable metal forms.
When the shaft lining adopts the fabricated template, in order to ensure the normal construction of the lining, the template support rod piece needs to have higher strength and rigidity so as to ensure the stability of the template support rod piece. The well-shaped beam or the full scaffold is often adopted for supporting, and the lateral pressure transferred by the template is radial, so that the supporting rod is not stressed in the axis, the requirements on strength and rigidity are high, the rod specifications are multiple, the dismounting and mounting procedures are complicated, and the construction efficiency is low.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a small cross section shaft lining cutting strutting arrangement adopts the I-steel arch ring as the support, and the dismouting is simple, and the location is accurate, and the structure is reliable, can practice thrift the cost, but reuse produces better society and economic benefits.
The technical scheme of the utility model is specifically as follows:
a lining supporting device for a small-section shaft comprises an annular supporting portion, wherein a plurality of layers of I-steel arch rings are arranged on the annular supporting portion, each layer of I-steel arch ring is composed of a plurality of sections of arc-shaped I-steel, connecting plates are arranged at two ends of each section of arc-shaped I-steel, and the plurality of arc-shaped I-steel are connected through the connecting plates.
Further, the connecting plate is provided with a bolt hole.
Furthermore, the connecting plate is vertically arranged at one end of the arc-shaped joist steel or obliquely arranged at one end of the arc-shaped joist steel.
Further, the supporting device is arranged in the small-section shaft lining.
Compared with the prior art, the beneficial effects of the utility model are specifically as follows:
(1) the utility model discloses utilize the I-steel arch ring as the inside lining, utilize the compressive property that steel is good to effectively resist the lateral pressure of newly-poured concrete to realize through the hoop that evenly the pressurized realizes that the structure is from steady, utilize the radial pressurized of arch ring to reach stable in structure in the concrete work progress, can effectively utilize material strength, and need not other member, simple and easy, favourable construction. The size is determined according to the design drawing, so that the template positioning is facilitated, and the deviation is reduced. The middle part can be used for building a construction platform, so that the interference of construction on the template is reduced, and the construction quality is improved.
(2) The utility model discloses a I-steel arch ring comprises a plurality of sections arc I-steel, and the dismouting is nimble, and the equipment is convenient, and arc I-steel both ends are equipped with the connecting plate, set up the connecting plate as required and be perpendicular or slope for the whole atress of arch ring is even.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some examples of the present invention, not all examples. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
Example 1
As shown in fig. 1, the utility model discloses a small cross section shaft lining cutting strutting arrangement, including annular supporting portion 3, be equipped with 2 layers of I-steel arch rings 1 on the annular supporting portion 3, each layer of I-steel arch ring 1 comprises if 4 sections arc I-steel, is A section, B section, C section and D section in proper order, as shown in fig. 2, every section arc I-steel both ends are equipped with connecting plate 2, connect through connecting plate 2 between 4 sections arc I-steel. Annular supporting part 3 can be constructed by the concrete, and the small section shaft lining 4 of outside construction, mid portion can be used to build construction platform, reduces the interference of construction to the template, improves construction quality.
As shown in fig. 5, the connecting plate 2 of the present invention is provided with 4 bolt holes, and one end of the i-steel is disposed on one side of the connecting plate 2. As shown in fig. 3, the connecting plates 2 of the section B and the section C are vertically arranged at two ends of the arc-shaped i-beam, the connecting plate 2 of one end of the section a and the section D is vertically arranged, the connecting plate 2 of the other end of the section a and the section D is obliquely arranged, and the connecting plate 2 of the section a and the connecting plate 2 of the section D are mutually matched, as shown in fig. 4.
The concrete construction steps of the embodiment are as follows:
step 1: as shown in fig. 1, the ABCD segments are sequentially installed, manually lifted and connected to the support part 3 with wire assist, and then the connecting bolts are installed after they are in place.
