Description
Technical field
The invention belongs to construction work safety protection technique field, relate in particular to a kind of high-rise building and reserve the hole means of defence.
Background technology
At present, in high-building construction, still keeping traditional job practices; Be exactly in building, to reserve one or several door openings or window opening; Stop layer as vertical transportation machinery and use, the provisional passage of confession personnel and material turnover is closed with its shutoff after waiting to build up.The existence at this hole brings great potential safety hazard for the construction operation personnel, and unit in charge of construction is in order to remove a hidden danger, and the interim retaining of iron wire rope of taking that has protects; The waste and old wooden form of the employing that has is its shutoff, and the measure that has is simple and crude or let alone to open wide, and these protect measure of performing practically no function not in place; On the one hand, bring inconsistent awkward image to the urbanization construction, on the other hand; Become the main cause of operating personnel's high falling; Particularly in the high-story house building operations,, in building engineering field, occupy the first place because of facing the high falling incident that hole, limit safeguard procedures problem causes always.
Summary of the invention
The object of the invention is exactly the above-mentioned shortcoming that exists to prior art, provides a kind of high-rise building to reserve the hole means of defence, and solution construction floor is reserved the hole is not had the security hidden trouble that closure is brought, and improves the civilized construction overall image.
A kind of high-rise building of the present invention is reserved the hole means of defence and is realized through following technical scheme.
The limit, body of wall outer or the outside ricker steel pipe that utilize each floor of construction work to reserve the hole are laid protective door; Under the effect of spacing outer baffle and returning pull-spring; Make the protective door state that keeps shut, and stop door leaf to be opened outwardly, the operating personnel can only get into from outside to inside; And can not from inside to outside door be pushed open, play and face hole, limit protective action.Get into the building storey hole when the constructor ascends a height through vertical transportation machinery, ecto-entad is pushed protective door open, gets into after the building storey hole, and the pulling force of returning pull-spring impels protective door to close voluntarily.When the constructor utilized go-cart to transport object through door leaf, crashproof backplate can play the effect of protection door leaf, avoided that door leaf is hit deformation effect and used, and the protective screening of protective door plays and stops buildings to fall from the gap location of door.
A kind of high-rise building of the present invention is reserved the hole means of defence, carries out according to the following steps:
1, makes the protection door leaf
The protection door leaf adopts square steel pipe or round steel pipe manufacturing to form, and material specification is: frame structure adopts 35mm * 35mm * 1.2 mm, intermediate support 25mm * 25mm * 1.0 mm, and round steel pipe can be with reference to the square steel pipe specification.Two fans were to equality about the protection door leaf was divided into, and width is decided with the size at hole, highly is not less than 1500 mm; The centre evenly is provided with the 3-5 root post to gain in strength, and stud materials is consistent with the protective door material.Door leaf protective screening and the totally-enclosed welding of doorframe that the protection door leaf adopts gauze wire cloth to do are fallen to prevent that object from exposing from crack between a door and its frame.Middle part at the protection door leaf adds crashproof backplate, and the position is split in the outside that is welded on the protection door leaf respectively, and crashproof backplate adopts the steel plate of appropriate thickness, and its width and length are that 1/3 of protective door is advisable, and available paint indicates the number of plies of floor on the crashproof backplate.Weld the tension spring internal fixation plate respectively in protection position, door leaf top and the bottom then, last extension spring internal fixation plate is positioned at the below 50--80mm of door leaf holder, and the top 50--80mm of door leaf holder was advisable under the tension spring internal fixation plate was positioned at.
2, make the doorframe fixed head
Protection doorframe fixed head adopts the 5-10mm steel plate to make; Be used for attached wall or attach the fixing use of pipe; Bore four holes at the position up and down of protection doorframe fixed head earlier during making, the aperture is slightly larger than expansion bolt or steel pipe U type fixed card external diameter, and pitch-row is had nothing in common with each other; Attach the pipe unit pitch-row and keep 50mm to be advisable, the wall-attaching equipment pitch-row is bigger to be advisable near the edge.Door leaf holder about welding on the protection doorframe fixed head, distance 1250 mm of door leaf holder are advisable.Welding two blocks of extension spring external fixation plates up and down on protection doorframe fixed head, it is corresponding up and down with the extension spring internal fixation plate that upper-lower position keeps, and should take into account the distance of spring stretching, extension and return simultaneously.Spacing outer baffle employing steel plate is made, and is welded on the below of door leaf holder on the doorframe fixed head respectively, and spacing Internal baffle adopts steel plate to make, and is welded on protection door leaf inboard respectively, and corresponding with spacing outer baffle position.
3, test return spring
Size according to different protective doors is selected return spring, and the extension spring of generally adopting the long 100mm of φ 25mm is as returning pull-spring.Spring test is carried out after first door leaf and doorframe fabrication and installation are in place, spring tension and return suitability with steady playback, easily unlatching is advisable, and tests first to be no less than an operation order of classes or grades at school, after the success of the test, confirms the spring specification.
4, make steel pipe U type fixed card
Select φ 12mm, long 180mm plain bars is made the screw thread screw thread at reinforcing bar two ends respectively, and screw thread is that 30mm is long.Center with reinforcing bar is a benchmark, on angle-bender, carries out the U type and makes, and U type radian can surround the 48mm scaffolding steel pipe and get final product.
5, expansion bolt is installed
Wall-attached uses the 8-10mm expansion bolt as the wall-attached fastening devices.The fixed head that will protect doorframe earlier before the installation vertically stands on body of wall, and expansion bolt is consistent in the position of body of wall and the bolt hole of fixed head.On body of wall, hole, expansion bolt is inserted in the hole, it is in place to protect doorframe then, utilizes expansion bolt that doorframe fixed head and body of wall are pre-fixed.
6, protective door is installed
After the doorframe fixed head pre-fixes, carefully proofread doorframe fixed head verticality, verticality is carried out bolton after correcting.With installing about the protective door branch, during installation door leaf is aimed at the door leaf holder, the door leaf rotating shaft is from top to bottom inserted, door leaf and doorframe are connected as one.
7, return spring is installed
After the protective door installation is proofreaied and correct, return spring is installed,,, is corrected test to satisfy the suitability of the self-closing performance of protective door if the loose excessively method of taking to shorten spring is corrected if tension takes the method for iron wire lengthening to correct at the position up and down of two doorframes.
For the integral body that increases this device and night effect, can adhere to protective door and have the fixedly reflectorised paint of colour code of safety.
Advantage compared with prior art of the present invention is that simple structure is pacified and torn open conveniently; Economic and practical, with low cost, can use repeatedly; Suitable high-story house is built to face on hole, limit body of wall or the steel pipe and is installed and used, and floor or building reservation hole are played the security protection effect.
