Description
Technical Field
The utility model relates to a permafrost region engineering field especially relates to a heat preservation template suitable for overhead structure.
Background
In the permafrost region, in order to prevent that the heat of building self from transmitting to the underground through the earth's surface and leading to the permafrost to melt, thereby lead to the ground bearing layer to change, finally produce harm to the ground, consequently many buildings all adopt cast-in-place bottom plate and earth's surface to break away from and form built on stilts hollow structure, this kind of built on stilts hollow structure ventiduct can promote the heat dissipation of permafrost, have heat preservation thermal-insulated and sunshade effect simultaneously, can effectively reduce the earth's surface temperature, avoid the building to melt to the thermal interference of permafrost, thereby guarantee the stability of pile foundation.
Because the permafrost region has low environmental temperature, in order to improve the heat preservation effect and reduce the heating cost, the bottom plate heat preservation needs to be made, the distance between the overhead floor and the bottom plate is usually lower, the construction space for the bottom plate heat preservation is small, the difficulty is high, the heat preservation under the cast-in-place bottom plate is increased after the construction of the cast-in-place bottom plate is completed, the construction is inconvenient, the heat preservation material and the cast-in-place bottom plate are firm and difficult to stick together, and the subsequent maintenance work.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a heat preservation template suitable for overhead structure that effectively solves bottom plate heat preservation construction difficulty, later maintenance work load is big is provided.
In order to solve the problem, a heat preservation template suitable for overhead structure, including arranging the reinforcing bar in the cast-in-place bottom plate of house main part bottom, its characterized in that: the bottom of the cast-in-place bottom plate is provided with a heat insulation material, and hard anticorrosive materials are laid on the upper surface and the lower surface of the heat insulation material; the steel bars and the heat insulation material are connected together through fixing bolts.
And a male and female clamping groove is formed at the joint of the heat insulation material and the hard anticorrosive material.
Compared with the prior art, the utility model has the following advantage:
1. the utility model discloses well insulation material is equipped with the public female draw-in groove with stereoplasm anticorrosive material's department of meeting, realizes zonulae occludens and does not keep the gap.
2. The utility model discloses the bottom of well cast-in-place bottom plate is equipped with insulation material, stereoplasm anticorrosive material is all laid to this insulation material's upper and lower surface, and reinforcing bar in the cast-in-place bottom plate passes through fixing bolt with insulation material and links together, not only replace traditional template work in the construction, and once only accomplish cast-in-place bottom plate heat preservation construction when a formwork pours, need not to demolish the template, increase the heat retaining secondary construction of bottom plate after having avoided cast-in-place bottom plate to accomplish again, it is difficult to have effectively solved bottom plate heat preservation construction, the later maintenance work load is big, also can show simultaneously and reduce engineering cost.
3. The utility model discloses the construction is simple, engineering efficiency is high.
Drawings
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partial a enlarged view of the present invention.
In the figure: 1-permafrost layer; 2, pile foundation; 3, the earth surface; 4, hollow in the air; 5, a house main body; 6, casting a bottom plate in situ; 7-hard anticorrosive material; 8, a heat insulation material; 9-fixing the bolt; and 10, reinforcing steel bars.
Detailed Description
As shown in figures 1-2, the heat-insulating template applicable to the overhead structure comprises a steel bar 10 arranged in a cast-in-place bottom plate 6 at the bottom of a house main body 5. The bottom of the cast-in-place bottom plate 6 is provided with a heat insulation material 8, and hard anticorrosive materials 7 are laid on the upper surface and the lower surface of the heat insulation material 8; the reinforcing steel bars 10 and the heat insulating material 8 are connected together through fixing bolts 9.
Wherein: and a male and female clamping groove is formed at the joint of the heat insulation material 8 and the hard anticorrosive material 7.
The hard anticorrosive material 7 is a plastic steel material, has anticorrosive property and certain rigidity strength.
A construction method of a heat preservation template suitable for an overhead structure comprises the following steps:
⑴ constructing the pile foundation 2 on the permafrost layer 1 and forming an overhead hollow 4 on the ground surface 3;
⑵ supporting the template bracket;
⑶ sandwiching a high-density heat-insulating material 8 between two layers of hard anticorrosive materials 7, and leaving a male and female clamping groove at the interface to obtain a novel heat-insulating template;
⑷ placing the new heat preservation template on the template bracket, laying pre-embedded steel bars 10 on the new heat preservation template, and connecting together by a plurality of fixing bolts 9;
⑸ constructing a cast-in-place bottom plate 6 supporting template at the bottom of the house main body 5;
⑹ pouring concrete to complete the construction of the cast-in-situ bottom plate 6;
⑺ when the strength of the concrete of the cast-in-situ soleplate 6 reaches the design requirement, the template bracket is removed, at this time, the cast-in-situ soleplate 6 forms a heat preservation layer and an anticorrosive layer, an overhead sunshade structure is formed between the building and the earth surface 3, the heat transfer from the building to the foundation is effectively isolated, the ventilation structure layer also promotes the heat dissipation of the earth surface, and simultaneously the heating effect of the solar radiation to the earth surface is blocked.
The embodiment is that a research station for frozen soil engineering and environmental comprehensive observation of the north foot river of the Tibet plateau of the academy of sciences of China (located in the abdominal region of the Tibet plateau, 34 degrees of north latitude 51.2', 92 degrees of east longitude 56.4', and 4628 meters of altitude) is located in a permafrost region. The area of the bottom plate of the house built in 2017 is 600m2Above, the bottom plate mode of keeping warm adopts the heat preservation template in the above-mentioned utility model, and the back heat preservation effect on probation is better. Meanwhile, the thickness of the insulation board is assumed to be 0.1m according to the field situation, and the density is 50kg/m3Coefficient of thermal conductivity 0.028W/(m).DEG C) and specific heat capacity of 1500J/(kg).deg.C); the concrete bottom plate has a thickness of 0.15m and a density of 2400 kg/m3Thermal conductivity coefficient of 1.74W/(m).Temperature is lower than that of the molten steel, and the specific heat capacity is 970J/(kg).deg.C); simulating the bottom temperature of the heat-insulating plate according to the field monitoring resultAre synthesized into
In the formulatAs a matter of time, the time is,φis the initial phase. Both initial temperatures were 5 ℃. The finite element software is used for simulating the temperature difference, and the result shows that the temperature difference between two sides of the current year in 11 months can reach 2 ℃, and the temperature difference between two sides of the current year in 12 months can reach 1.5 ℃. Therefore, the method has better heat preservation effect.
