Problems solved by technology

This patent mainly detects the wind pressure resistance of the exterior wall by generating wind pressure in the negative pressure box, but the performance of the exterior wall in heat / rain, heat / cold and other environments cannot be tested, so another test is required for detection. Greatly increased the detection cost and cycle, and could not carry out systematic detection against wind pressure and heat / rain, heat / cold and other environments at the same time, making the detection data not comprehensive enough, affecting the development of new exterior wall materials and the improvement of construction technology

Embodiment 1

[0031] Such as Figure 1 to Figure 5 As shown, a weather resistance testing device for exterior wall specimens, such as figure 1 , figure 2 , image 3 As shown, it includes a square-shaped environmental box 111 and a frame 211 for fixing the outer wall test piece. The environmental box 111 is made of polyurethane thin steel plate composite material. The environmental box 111 is also equipped with a door 141. An observation hole 142 is opened on the door 141, and the observation hole 142 is sealed by glass; an inlet 121 is opened on the side of the environmental box 111, and a sealing strip is provided around the inlet 121 on the side of the environmental box 111, and the outer wall test piece can be against the inlet 121 On the sealing strip on the side of the surrounding environment box 111, the frame 211 is connected with a power guide mechanism that can push the frame 211 to abut against the side of the environment box 111 and enable the outer wall test piece on the fram...

Embodiment 2

[0041] The structure and principle of the present embodiment are basically the same as those of the first embodiment, except that the bottom of the environmental chamber 111 is fixed with a number of support feet 131 that can make it stand up, and there are four support feet 131 in the second embodiment, respectively Located at the four corners of the bottom of the environmental box 111, a gap is formed between the bottom of the supporting leg 131 and the bottom of the environmental box 111. The power guiding mechanism includes a guide rail 221, a bottom plate 231, a nut, a screw and a motor, and the guide rail 221 passes through the above-mentioned gap. and the guide rail 221 is perpendicular to the side of the environmental chamber 111 with the inlet 121, the frame 211 is fixed on the bottom plate 231, and the outer wall specimen fixed on the frame 211 is perpendicular to the guide rail 221, and the lower part of the bottom plate 231 is provided with several energy The roller...

Embodiment 3

[0043] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that: Figure 6 As shown, there are two inlets 121 on the environmental box 111, which are respectively opened on the two sides of the environmental box 111. There are also two corresponding frames 211. Both the power guiding mechanism and the locking mechanism are two. The power guiding mechanism and the locking mechanism Same as the power guiding mechanism and locking mechanism in Embodiment 1, there are six fans 361 in Embodiment 3, which are divided into two groups, each group is three, facing two inlets 121 respectively; there are two groups of outlet pipes 432, They are located at two entrances 121 respectively. Setting up two entrances 121 can test two external wall test pieces at the same time, which reduces the product development cycle and saves development costs.

Abstract

The invention provides a weather resistance detection device for an outer wall test piece and belongs to the technical field of measurement. The weather resistance detection device solves the technical problems that existing weather resistance detection devices for the outer wall test piece cannot perform system detection simultaneously on wind pressure resistance and the environment of heat / rain and the like, so that detection data are not comprehensive enough and development of an outer wall is influenced, and the like. The weather resistance detection device for the outer wall test piece comprises an environmental box and a frame for fixing the outer wall test piece. The side of the environmental box is provided with an inlet, a heating system enabling the temperature in the environmental box to rise and a refrigerating system enabling the temperature in the environmental box to be lowered are arranged in the environmental box, a spraying system is further arranged in the environmental box and comprises a plurality of spray heads, water outlets of the spray heads are towards the inlet, and a control system capable of controlling the heating system, the refrigerating system and the spraying system is further arranged at the position of the environmental box. The weather resistance detection device has the advantages that the environmental box can simulate various natural environments through the heating system, the refrigerating system, the spraying system and a fan, and detection is comprehensive.

Description

technical field [0001] The invention belongs to the technical field of measurement, and relates to a detection device for an exterior wall test piece, in particular to a weather resistance detection device for an exterior wall test piece. Background technique [0002] In recent years, with the rapid development of our country's economy, energy has become tense. Under the background of world energy shortage, my country's energy shortage is particularly serious, which has endangered the steady implementation of the social sustainable development strategy. Building energy consumption is a major energy consumer in my country. Relevant experts pointed out that at present, the energy consumption of buildings in China accounts for more than 28% of the total energy consumption of the society (the heating energy consumption in the northern region exceeds 40% of the total energy consumption of the local society). Therefore, building energy saving is undoubtedly an important part of ...
