Abstract

The wall structure comprises outer and inner walls of brick and reinforced concrete, and it features the filler between outer and inner walls and the built-in steel bars which combine the walls firmly through spot welding. The filler is light flame-retarded foamed plastics. The present invention makes the building light, warm, anti-seismic and low in cost.

Description

The hollow heat-insulating wall structure

The present invention relates to house wall structure in the building field, is a kind of hollow heat-insulating wall structure specifically.

The cold district brick wall reaches the 900-530 millimeters thick at present, adds the hot-water heating facility, and consumptive material is costly.Because of insulation needs, being difficult to of floor height is considerable, and it is many that the room is on average taken up an area of, and wastes a large amount of land resourcess.Structures such as its foundation platform are expensive surprising especially.People carry out all improvement design, design the hollow wall structure the house wall structure of cold district for this reason.Authorized on May 23rd, 90 as Patent Office of the People's Republic of China, the patent No. is 87103460, and name is called combined small board, instant poured netting check and hollow wall body construction process patent.This patent uses the special thin wallboard to cooperate cross section to be H shape, in fix through anchor clamps every building block with holes, cast-in-place post, beam, and with this with the fixed grid frame load bearing hollow body of wall that becomes of wallboard.This technology efficiency of construction improves 4-5 doubly than 24 brick walls, and cost is about standard brick wall 50%, and performances such as its structural strength and insulation, heat insulation, sound insulation, damp proof insulation, antidetonation are all better.

The object of the present invention is to provide that a kind of building is totally light, cold-resistant, antidetonation, shock-resistant, firm safe, improve the building area instream factor, reduce the hollow heat-insulating wall structure of comprehensive cost.

To achieve these goals, the present invention adopts following technical scheme: a kind of hollow heat-insulating wall structure, comprise outer body of wall and interior body of wall, it is characterized in that: inserts is set in the middle of the external and internal wall, and reinforcing bar and the body of wall strong bonded of burying mutual spot welding connection in the body of wall and between body of wall underground are one.

The external and internal wall of hollow heat-insulating wall structure of the present invention can be built into by bat.

In the external and internal wall of hollow heat-insulating wall structure of the present invention, wherein a body of wall can be built into for bat, and another body of wall is an armored concrete slab.

Inserts between hollow heat-insulating wall structure external and internal wall of the present invention is a light flame-retarded foamed plastics.

Good effect of the present invention is:

1, alleviates the building deadweight.Compare, conduct oneself with dignity minimizing 2-4 doubly with the stack pile solid wall, totally feed intake and save more than 38%, enlarge effective area about 18%, comprehensive cost reduces more than 8%.

2, reduce indirect expense and loss.The practical efficiency of building body all has only 81-63% because all kinds of building materials put in place, and in the engineering construction, the building materials input is many at present, and the phase of getting the raw materials ready is long, and the carrying amount is big, and incidentals are many, and loss is big, and the stockyard is huge, and twists and turns are many.And the present invention had both saved material owing to adopt the hollow wall structure, reduced the twists and turns of getting the raw materials ready again.

3, shorten construction period.Engineering construction at present, it is many to feed intake, and outside the phase of getting the raw materials ready was long, the foundation platform engineering quantity was big, and it is various to employ mechanical facility, and construction is complicated, the duration is oversize.Feed intake fewly and implement the present invention, the construction of getting the raw materials ready is all fast, bears the building in the area more than 8 tons in the soil property standard, and commercial and residential building below eight layers does not need basis piling or irritates stake, gets rid of a large amount of basic mechanical execution amounts, has changed construction content.If Construction Plan is tight,, shorten construction period 1/3-2/5 even rainy day low temperature also can continue indoor construction.

4, saving metal material and energy, cold-resistant insulation, building is of high grade.The cold district brick wall has 900,780,530 or 200 millimeters thick concrete wall, and implementing the present invention respectively can 350,200, the millimeters thick body of wall is competent substitutes.

Below in conjunction with drawings and Examples the present invention is elaborated.

Fig. 2 is the A-A rotation generalized section of Fig. 1;

Fig. 3 is the sequence of construction schematic diagram of a preferred embodiment of the present invention;

Fig. 4 is the vertical section structural representation of another preferred embodiment of the present invention;

Fig. 5 is the B-B rotation generalized section of Fig. 4.

Embodiment 1:

Seeing also Fig. 1, Fig. 2 and shown in Figure 3, is a preferred embodiment of the present invention.Outer body of wall 1 and interior body of wall 2 are built into by bat 3, in the middle of the inside and outside brick wall inserts 4 light flame-retarded foamed plastics are set and make insulation layer, bury the reinforcing

bar

5,6,7 that mutual spot welding connects in the brick wall and between brick wall underground.Sequence of construction: the outer bat body of wall 1 of first step hollow wall puts in place, wherein thickness direction reinforcing bar S length is 300～150m/m, it is uniform that the vertical-horizontal spacing is the 350m/m left and right sides, firmly be welded in the wall basis of same level with length direction reinforcing bar 6, spacing 350m/m left and right horizontal is put, and material is that diameter 6.5m/m-diameter 3m/m builds first steel or draw piece unit steel.Length direction reinforcing bar 6 gives and being embedded in the outer half brick wall 1, and is firm with 5 spot welding of thickness direction reinforcing bar.Thickness direction reinforcing bar 5 be exposed at inboard in a row about, level interval is 350m/m.The outer body of wall 1 that can finish whole building this moment earlier whitewashes and decorates.Also can construct synchronously by interior exterior wall 1,2.Second step is at the floor indoor construction, even rainy day, low temperature also can carry out.The unit inserts 4 light flame-retarded foamed plastics insulation layers that are equal to the body of wall geometry, reinforcing bar 5 file leader's of penetration thickness direction, be close on the outer half brick wall 1, expose on the 80-40m/m steel bar end point weld in length direction reinforcing bar 7 in the bat body of wall 2, build be embedded in in the bat body of wall.This moment, the structure of whole hollow wall was all finished.

Embodiment 2:

Seeing also Fig. 4 and Fig. 5, is another preferred embodiment of the present invention.Outer body of wall 30 is to be built into by bat, and interior body of wall 20 is armored concrete slabs, and the centre is provided with inserts 40 insulation layers.Sequence of construction: the outer half brick wall 30 of first step hollow wall puts in place, and its job practices is with first embodiment, so no longer repeat.Second step was implemented interior body of wall 20, the unit inserts 40 light flame-retarded foamed plastics insulation layers that are equal to the body of wall geometry, penetrate at thickness direction reinforcing bar 50 file leader's, be close on the outer half brick wall 30, expose the 80-40m/m reinforcing bar, on exposed steel bar end in the vertical spot welding concrete slab behind the skeleton 100m/m pattern steel mesh reinforcement 60, technology is irritated concrete again and is become interior body of wall 20 routinely.Promptly finish the overall structure of hollow wall.

The present invention also can adopt external and internal wall to be armored concrete slab, middle perfusion heat insulating stuffing structure.The hollow heat-insulating wall structure, optimal job practices is: by hollow requirement forming hollow steady type body of wall.The insulation packing layer of cavity is dashed to fill out by the scene and puts in place, and its speed of application is faster and better.Its moistureproof heat-insulating property is even more ideal.
